    日本語, 研究論文(学術雑誌), We report a case of testicular cancer after kidney transplantation in a 29-year-old man. Twenty-two years after the surgery, computed tomography (CT) showed a retroperitoneal mass 3 cm in diameter. Positron emission tomography (PET) -CT revealed high FDG uptake in both the right testis and retroperitoneal mass. Regarding serum tumor markers, α fetoprotein (AFP) was slightly elevated to 12.5 ng/ml. He underwent right radical orchiectomy, and pathological examination revealed pure seminoma. After surgery, the serum AFP level remained high (12. 9 ng/ml), and we initially considered this nonseminoma patient to have a good prognosis according to International Germ Cell Consensus Classification. During three cycles of a combination regimen including bleomycin, etoposide, and cisplatin (BEP), we performed adjustment of immunosuppressive therapy, treatment for Cytomegalovirus infection (valganciclovir hydrochloride), and that for other adverse events associated with systemic chemotherapy. The chemotherapy schedule was delayed, and bleomycin (third course, day 15) was skipped due to adverse effects. After 3 cycles of BEP, the retroperitoneal lymph node metastasis shrunk from 3.0 to 1.5 cm in diameter. In contrast to the good radiological response, the serum AFP level gradually increased during the treatment to 102.6 ng/ml. Therefore, we did not consider the AFP elevation to have derived from residual cancer, and decided to perform close follow-up. During the 3-year follow-up, AFP decreased to around 20 ng/ml, and PET-CT did not show any uptake in the retroperitoneal mass or other sites.

    研究論文(学術雑誌), Abstract

    Background

    The Banff Working Group has updated the histological classification of BK virus nephropathy (BKVN), highlighting the importance of early detection. However, an early detection strategy for BKVN using biopsy has not yet been established. Our investigation aimed to assess the efficacy of protocol biopsy for the diagnosis of BKVN.

    Methods

    We performed a retrospective cohort study of 314 patients who had undergone kidney transplantation between 2006 and 2021. Kidney allograft biopsies were performed as part of a protocol biopsy at 3 months and 1 year post‐transplantation. Following the diagnosis of BKVN, the immunosuppressant dose was reduced.

    Results

    Twelve patients (3.8%) were diagnosed with BKVN by biopsy. Most diagnoses are established during the early stages of BKVN (polyomavirus nephropathy class 1 in six, class 2 in five, and class 3 in one). Following the reduction in immunosuppressant dose, kidney allograft function did not deteriorate in any patients. Additionally, test for BK virus DNA in the blood was negative. All but one patient demonstrated histological resolution of BKVN, and the other had a very slight positivity for the simian virus 40 large T antigen. The median follow‐up time after BKVN diagnosis was 6 years. One patient developed de novo donor‐specific antibody and subclinical acute antibody‐mediated rejection that was successfully cured.

    Conclusions

    Our analysis indicates that protocol biopsy may enable the early detection of BKVN, resulting in the preservation of kidney function.image

    研究論文(学術雑誌), This study developed and validated a surgical instrument motion measurement system for skill evaluation during practical laparoscopic surgery training. Owing to the various advantages of laparoscopic surgery including minimal invasiveness, this technique has been widely used. However, expert surgeons have insufficient time for providing training to beginners due to the shortage of surgeons and limited working hours. Skill transfer efficiency has to be improved for which there is an urgent need to develop objective surgical skill evaluation methods. Therefore, a simple motion capture–based surgical instrument motion measurement system that could be easily installed in an operating room for skill assessment during practical surgical training was developed. The tip positions and orientations of the instruments were calculated based on the marker positions attached to the root of the instrument. Because the patterns of these markers are individual, this system can track multiple instruments simultaneously and detect exchanges. However due to the many obstacles in the operating room, the measurement data included noise and outliers. In this study, the effect of this decrease in measurement accuracy on feature calculation was determined. Accuracy verification experiments were conducted during wet-lab training to demonstrate the capability of this system to measure the motion of surgical instruments with practical accuracy. A surgical training experiment on a cadaver was conducted, and the motions of six surgical instruments were measured in 36 cases of laparoscopic radical nephrectomy. Outlier removal and smoothing methods were also developed and applied to remove the noise and outliers in the obtained data. The questionnaire survey conducted during the experiment confirmed that the measurement system did not interfere with the surgical operation. Thus, the proposed system was capable of making reliable measurements with minimal impact on surgery. The system will facilitate surgical education by enabling the evaluation of skill transfer of surgical skills.

    International journal of urology : official journal of the Japanese Urological Association, 2024年01月19日, [国際誌]
    英語, 研究論文(学術雑誌), OBJECTIVES: Previous studies suggested that living kidney donors do not have a higher risk of death or kidney failure than the general population. However, living kidney donor risk is controversial. Furthermore, only a few studies have evaluated long-term kidney function after kidney donation. METHODS: This study evaluated Japanese kidney donor' long-term outcomes, including mortality and kidney function. From 1965 to 2015, 230 donors (76 males, 154 females, and a median age of 54) were enrolled in this study. The median observation period was 11.0 (range, 0.3-41.0) years. RESULTS: In total, 215 donors were still alive, and 15 had died. Causes of death included malignancies, cardiovascular disease, pneumonia, suicide, gastrointestinal bleeding, and kidney failure. Actual donor survival rates at 10, 20, and 30 years were 95.3%, 90.7%, and 80.9%, respectively. These values were comparable to age- and gender-matched expected survival. Long-term kidney function after donation was evaluated in 211 donors with serum creatinine data. Two donors developed kidney failure 24 and 26 years post-donation, respectively. The percentage of donors whose estimated glomerular filtration rate (eGFR) remained ≥45 mL/min/1.73 m2 at 10, 20, and 30 years after donation were 84.2%, 73.0%, and 63.9%, respectively. Survival rates of donors with eGFR <45 mL/min/1.73 m2 were comparable to those in persons with eGFR >45 mL/min/1.73 m2 . CONCLUSION: Our findings revealed that kidney donors did not have a higher long-term risk of death than the general population. Although some donors showed decreased kidney function after donation, kidney function did not impact their survival.

    英語, 研究論文(学術雑誌), INTRODUCTION: Calcineurin inhibitor (CNI)-induced nephrotoxicity (CNI-T) is a post-transplantation complication that leads to graft dysfunction. Older-donor kidney grafts may be susceptible to chronic CNI exposure because of long-term arteriolar damage. The primary aim of this study was to examine the CNI-T incidence and time-course changes in the graft function according to donor age. METHODS: We included 334 kidney transplant recipients. CNI-T was defined by Banff arteriolar hyaline thickening scores of ≥2 based on allograft protocol biopsy. Depending on donor age, participants were divided into the D > 70 (≥70 years), D60 (60-69 years), D50 (50-59 years), and D < 49: (≤49 years) groups. We investigated the extent to which CNI-T affected the transplanted kidney function. Patients who did not develop CNI-T during the study period were included in the non-CNI-T group; the remaining were grouped into the CNI-T group. RESULTS: The CNI-T incidence was higher in donors aged >50 years. Compared to D < 49, the CNI-T risk was 1.86 times higher in D50 and 2.9 times higher in D > 70. Furthermore, the CNI-T group exhibited a significantly lower graft function 10 years after transplantation. CONCLUSION: CNI-T incidence increases in donors aged ≥50 years and affects renal function after 10 years.

    英語, 研究論文(学術雑誌), BACKGROUND: Thrombotic microangiopathy (TMA) after kidney transplantation (KTx), particularly early onset de novo (dn) TMA, requires immediate interventions to prevent irreversible organ damage. This multicenter study was performed to investigate the allogeneic clinical factors and complement genetic background of dnTMA after KTx. METHODS: Perioperative dnTMA after KTx within 1 week after KTx were diagnosed based on pathological or/and hematological criteria at each center, and their immunological backgrounds were researched. Twelve aHUS-related gene variants were examined in dnTMA cases. RESULTS: Seventeen recipients (15 donors) were enrolled, and all dnTMA cases were onset within 72-h of KTx, and 16 of 17 cases were ABO incompatible. The implementation rate of pre-transplant plasmaphereses therapies were low, including cases with high titers of anti-A/anti-B antibodies. Examination of aHUS-related gene variants revealed some deletions and variants with minor allele frequency (MAF) in Japan or East Asian genome databases in genes encoding alternative pathways and complement regulatory factors. These variants was positive in 8 cases, 6 of which were positive in both recipient and donor, but only in one graft loss case. CONCLUSIONS: Although some immunological risks were found for dnTMA after KTx, only a few cases developed into TMA. The characteristic variations revealed in the present study may be novel candidates related to dnTMA in Japanese or Asian patients, but not pathogenic variants of aHUS. Future studies on genetic and antigenic factors are needed to identify factors contributing to dnTMA after KTx.

  • Use of Mixed Lymphocyte Reaction Assay to Evaluate Immune Tolerance before Kidney Transplantation with an Immunosuppression-Free Protocol following Hematopoietic Stem Cell Transplantation from the Same Donor.

    英語, Several cases of kidney transplantation after hematopoietic stem cell transplantation (HSCT) from the same donor for end-stage renal disease have been reported. In those cases, immunosuppressive drugs were discontinued since immune tolerance was supposed to be induced. Theoretically, the recipient's immune system recognizes the kidney allograft as its own tissue with the same human leukocyte antigen (HLA) profile, and the kidney allograft will not be rejected, even without the use of immunosuppressive agents. However, almost all recipients receive immunosuppressants in the early stages after kidney transplantation owing to concerns of acute rejection. Here, we report a successful case of post-HSCT kidney transplantation without the use of immunosuppressive drugs, in which a mixed lymphocyte reaction (MLR) assay was used to evaluate immune tolerance before kidney transplantation. The patient was a 25-year-old woman. Five years prior, she developed acute myeloid leukemia and underwent HLA-half-matched peripheral blood stem cell transplantation. Thereafter, she was in remission of the acute myeloid leukemia, but 1 year later, she developed renal graft-versus-host disease. Subsequently, the patient's renal function gradually deteriorated to end-stage renal failure, and she underwent kidney transplantation with the previous stem cell donor: her mother. HLA typing of donor and recipient showed a complete chimerism in the peripheral blood. The pretransplantation complement-dependent cytotoxic crossmatch and flow cytometric T-cell crossmatch results were both negative, and HLA antibody measurements were all negative. The MLR assay revealed no T-lymphocyte reaction to the donor; therefore, immunosuppressants were not used. Two years after transplantation, the patient's serum creatinine concentration was around 0.8 mg/dL (down from 4 mg/dL before transplantation). No abnormalities were observed in a renal biopsy performed after 3 months. Our study, along with others, indicates that immune tolerance to a donor develops in post-HSCT kidney transplantation from the same donor.

    英語, 研究論文(学術雑誌), Donor-specific antibodies (DSAs) are the main cause of graft loss over time. The direct pathway of alloantigen recognition is important in the pathogenesis of acute rejection. Recent studies have suggested that the direct pathway also contributes to the pathogenesis of chronic injury. Nevertheless, there are no reports on T-cell alloantigen response via the direct pathway in kidney recipients with DSAs. We analyzed the T-cell alloantigen response via the direct pathway in kidney recipients with DSAs (DSA+) or without DSAs (DSA-). A mixed lymphocyte reaction assay was implemented to assess the direct pathway response. DSA+ patients showed significantly higher CD8+ and CD4+ T cell responses to donor cells than DSA- patients. Furthermore, proliferating CD4+ T cells showed a marked increase in Th1 and Th17 responses in DSA+ patients than in DSA- patients. In a comparison between anti-donor and third-party responses, the anti-donor CD8+ and CD4+ T cell response was significantly lower than the anti-third-party response. In contrast, the donor-specific hyporesponsiveness was absent in DSA+ patients. Our study demonstrated that DSA+ recipients have a greater potential for developing immune responses against the donor tissues via the direct alloantigen recognition pathway. These data contribute to an understanding of DSAs pathogenicity during kidney transplantation.

    英語, 研究論文(学術雑誌), During the last four decades, development of effective immunosuppressants has significantly improved short-term results of organ transplantation. However, long-term results have not been satisfactory due to chronic rejection or complications caused by immunosuppressive drugs. Therefore, induction of immunological tolerance of the transplanted organ is considered essential to improve the long-term results. Despite numerous tolerance strategies that have been successful in murine models, inducing hematopoietic chimerism through donor hematopoietic stem cell transplantation is the only method that reproducibly induces kidney allograft tolerance in nonhuman primates or humans. Combining kidney and hematopoietic stem cell transplantation to achieve allograft tolerance has now been attempted with different chimerism strategies. This review summarizes the status of current clinical trials on the induction of allograft tolerance. We also summarize recent studies to extend the chimerism approach to deceased donor transplant recipients.

    研究論文(学術雑誌), Background

    To seek insights into the pathogenesis of chronic active antibody–mediated rejection (CAMR), we performed mRNA analysis and correlated transcripts with pathologic component scores and graft outcomes.

    Methods

    We utilized the NanoString nCounter platform and the Banff Human Organ Transplant gene panel to quantify transcripts on 326 archived renal allograft biopsy samples. This system allowed correlation of transcripts with Banff pathology scores from the same tissue block and correlation with long-term outcomes.

    Results

    The only pathology score that correlated with AMR pathways in CAMR was peritubular capillaritis (ptc). C4d, cg, g, v, i, t, or ci scores did not correlate. DSA-negative CAMR had lower AMR pathway scores than DSA-positive CAMR. Transcript analysis in non-CAMR biopsies yielded evidence of increased risk of later CAMR. Among 108 patients without histologic CAMR, 23 developed overt biopsy-documented CAMR within 5 years and as a group had higher AMR pathway scores (P=3.4 × 10–5). Random forest analysis correlated 3-year graft loss with elevated damage, innate immunity, and macrophage pathway scores in CAMR and TCMR. Graft failure in CAMR was associated with TCMR transcripts but not with AMR transcripts, and graft failure in TCMR was associated with AMR transcripts but not with TCMR transcripts.

    Conclusions

    Peritubular capillary inflammation and DSA are the primary drivers of AMR transcript elevation. Transcripts revealed subpathological evidence of AMR, which often preceded histologic CAMR and subpathological evidence of TCMR that predicted graft loss in CAMR.

    英語, This paper describes details of the development of skill evaluation system for laparoscopic surgical procedure. The measurement experiment was conducted for 70 surgeons, and the participants perform 2 tasks: tissue dissection around the aorta and renal parenchymal suturing/knotting using porcine cadaver. In the experiments, the movement of surgical instruments were recorded by motion capture (MoCap) system, and the motion indices were calculated. The participants grouped into three classes (novices, intermediates, and experts) according to their level of experience. Three classification algorithms: support vector machine (SVM), principal component based SVM (PCA-SVM), gradient boosting decision tree (GBDT) were utilized for developing the model of classifier. The accuracy of each model was assessed by nested and repeated k-fold cross validation. Regarding 3-class classification, the GBDT method resulted highest accuracy (the median of the accuracy is A_med = 68.6 %) in the dissection tasks. In the suturing/knotting tasks, PCA-SVM resulted highest accuracy (A_med = 58.4 %). Regarding 2-class classification (experts vs. intermediates/novices), the GBDT method resulted A_med = 72.9 % in the dissection task, and the PCA-SVM method resulted A_med = 69.2 % in the suturing task. This result shows the MoCap based skill evaluation system in wet-lab training could be a practical way to objectively assess trainees' surgical competence.

    英語, 研究論文(学術雑誌), OBJECTIVES: The impact of vesicoureteral reflux post-kidney transplantation on graft survival remains unclear, and guidelines on appropriate vesicoureteral reflux management post-kidney transplantation are lacking. For this reason, we conducted a retrospective study on the impact of vesicoureteral reflux and its treatment on graft survival. METHODS: We evaluated 347 consecutive kidney transplantation recipients, who also underwent a ureteroneocystostomy, between 1996 and 2012. RESULTS: Vesicoureteral reflux was diagnosed in 55 cases (15.9%), with a median post-kidney transplantation duration of 50 months (range 0-172 months). Among these, 22 were monitored, 17 underwent transurethral collagen injections, and 16 received a ureteroneocystostomy. The 10-year graft survival rate was significantly lower in recipients with vesicoureteral reflux (68.9%) than in those without vesicoureteral reflux (84.4%) (P = 0.0165). Moreover, among the vesicoureteral reflux recipients, the 10-year graft survival rate was significantly higher in those whose vesicoureteral reflux was cured (80.1%) than in those whose vesicoureteral reflux persisted (53.6%) (P = 0.0062). Multivariate analysis showed that vesicoureteral reflux was significantly associated with both overall and death-censored graft loss (odds ratio 3.737 and 3.685; P = 0.0015 and P = 0.0052, respectively). Lastly, the incidence of interstitial fibrosis and tubular atrophy was higher in recipients with vesicoureteral reflux than in those without vesicoureteral reflux (P = 0.0009). CONCLUSIONS: Post-kidney transplantation vesicoureteral reflux has a negative impact on long-term graft survival, and that treatment prevents graft deterioration. From the perspective of maintaining long-term graft function in kidney recipients, vesicoureteral reflux may be one of the most important complications to be addressed.

    日本語, 研究論文(学術雑誌), We report a case of bladder cancer in a 54-year-old woman who underwent renal transplantation for chronic renal failure. Six years after the transplantation, she was diagnosed with muscle-invasive bladder cancer with multiple lung metastases. She received gemcitabine/cisplatin therapy for Stage IV bladder cancer, and the dose of the immunosuppressants was reduced to prevent adverse effects. Since lung metastatic lesions disappeared after four courses of chemotherapy and no new lesions were found, we performed radical cystectomy and right nephroureterectomy with ileal conduit construction. Although she was followed closely without therapy, multiple lung metastases appeared 6 months after the radical cystectomy. Gemcitabine/carboplatin therapy was administered, and the lung metastasis improved slightly until the end of the 4th course, but aggressive growth was observed after the 5th course. She switched to palliative treatment without requesting additional treatment and died of cancer 1 year and 9 months after total cystectomy.There is no evidence-based treatment strategy for advanced bladder cancer after kidney transplantation. It is necessary to recognize that the patient had renal dysfunction and was in an immunosuppressed state. Thus, it is crucial to select appropriate drug and surgical treatments for each patient.

    英語, 研究論文(学術雑誌), Isohemagglutinin assays employing red blood cells (RBCs) are the most common assays used to measure antibody titer in ABO-incompatible kidney transplantation (ABOi KTx). However, ABO antigens expressed on RBCs are not identical to those of kidney and antibody titers do not always correlate with clinical outcome. We previously reported that CD31 was the main protein linked to ABO antigens on kidney endothelial cells (KECs), which was different from those on RBCs. We developed a new method to measure antibody titer using a microarray of recombinant CD31 (rCD31) linked to ABO antigens (CD31-ABO microarray). Mass spectrometry analysis suggested that rCD31 and native CD31 purified from human kidney had similar ABO glycan. To confirm clinical use of CD31-ABO microarray, a total of 252 plasma samples including volunteers, hemodialysis patients, and transplant recipients were examined. In transplant recipients, any initial IgG or IgM antibody intensity >30,000 against the donor blood type in the CD31-ABO microarray showed higher sensitivity, specificity, positive predictive value, and negative predictive value of AABMR, compared to isohemagglutinin assays. Use of a CD31-ABO microarray to determine antibody titer specifically against ABO antigens expressed on KECs will contribute to precisely predicting AABMR or preventing over immunosuppression following ABOi KTx.

    英語, 研究論文(学術雑誌), The purpose of this study was to characterize the motion features of surgical devices associated with laparoscopic surgical competency and build an automatic skill-credential system in porcine cadaver organ simulation training. Participants performed tissue dissection around the aorta, dividing vascular pedicles after applying Hem-o-lok (tissue dissection task) and parenchymal closure of the kidney (suturing task). Movements of surgical devices were tracked by a motion capture (Mocap) system, and Mocap-metrics were compared according to the level of surgical experience (experts: ≥50 laparoscopic surgeries, intermediates: 10-49, novices: 0-9), using the Kruskal-Wallis test and principal component analysis (PCA). Three machine-learning algorithms: support vector machine (SVM), PCA-SVM, and gradient boosting decision tree (GBDT), were utilized for discrimination of the surgical experience level. The accuracy of each model was evaluated by nested and repeated k-fold cross-validation. A total of 32 experts, 18 intermediates, and 20 novices participated in the present study. PCA revealed that efficiency-related metrics (e.g., path length) significantly contributed to PC 1 in both tasks. Regarding PC 2, speed-related metrics (e.g., velocity, acceleration, jerk) of right-hand devices largely contributed to the tissue dissection task, while those of left-hand devices did in the suturing task. Regarding the three-group discrimination, in the tissue dissection task, the GBDT method was superior to the other methods (median accuracy: 68.6%). In the suturing task, SVM and PCA-SVM methods were superior to the GBDT method (57.4 and 58.4%, respectively). Regarding the two-group discrimination (experts vs. intermediates/novices), the GBDT method resulted in a median accuracy of 72.9% in the tissue dissection task, and, in the suturing task, the PCA-SVM method resulted in a median accuracy of 69.2%. Overall, the mocap-based credential system using machine-learning classifiers provides a correct judgment rate of around 70% (two-group discrimination). Together with motion analysis and wet-lab training, simulation training could be a practical method for objectively assessing the surgical competence of trainees.

    英語, 研究論文(学術雑誌), Long-term calcineurin inhibitor (CNI) administration causes irreversible nephrotoxicity. Therefore, early CNI-induced nephrotoxicity detection is necessary for patients who will need long-term CNI administration. There is no pathological indicator for early CNI-induced nephrotoxicity. Here, serial protocol kidney biopsy specimens from five kidney-transplant patients with severe CNI-induced nephrotoxicity were examined. We observed that the increase in CD44 expression in glomerular parietal epithelial cells (PECs) preceded the chronic pathological changes of CNI-induced nephrotoxicity such as tubular atrophy/interstitial fibrosis, arterial hyaline thickening, and focal segmental glomerulosclerosis (FSGS). This result suggests that CD44-positive PECs have pivotal roles in FSGS development in human CNI-induced nephrotoxicity as well as rodent models. CD44 could be useful as a pathological marker for early CNI-induced nephrotoxicity detection post kidney transplantation.

    英語, INTRODUCTION: We report a rare case of primary renal leiomyosarcoma with a tumor thrombus in the inferior vena cava. CASE PRESENTATION: A 54-year-old woman presented with right flank pain and abdominal distension. Physical examination findings were unremarkable. Abdominal computed tomography revealed a heterogeneously enhancing right solid renal mass with a thrombus in the renal vein extending into the inferior vena cava. Magnetic resonance imaging demonstrated a renal tumor with a thrombus about 4 cm below the hepatic vein. Chest computed tomography and bone scintigraphy were negative. The patient underwent right radical nephrectomy and vena cava thrombectomy. Histophathologic evaluation of the resected tumor confirmed the diagnosis of leiomyosarcoma. She underwent no adjuvant therapy. Seven months after surgery, the patient died following a 2-month history of multiple pulmonary and hepatic metastases. CONCLUSION: This report highlights the importance of considering the possibility of renal leiomyosarcoma invasion to the inferior vena cava, similar to renal cell carcinoma.

    英語, Background: A positive flow-cytometry T cell crossmatch (FTXM) has important prognostic implications, even when the complement-dependent cytotoxicity crossmatch is negative. Recent studies have shown that ABO incompatibility is associated with positive FTXM, but the underlying mechanism remains poorly understood. Cases: In five ABO blood type O recipients of kidneys from wives with type B, FTXM was positive but complement-dependent cytotoxicity crossmatch was negative. Application of a solid-phase technique (LABScreen) revealed no case with antibodies to donor-specific human leukocyte antigen. After removal of type B antibodies from patient sera, FTXM was negative for all five patients. In one tested case, the eluate prepared from the donor's T lymphocyte agglutinated only type B red blood cells, implying the existence of blood type B substances on donor T lymphocytes. Discussion: False-positive FTXM reflects blood type B substrates bound to T lymphocytes. Repeat FTXM after incubation with donor-type red blood cells (to adsorb anti-ABO antibodies) was negative. This phenomenon explains the discrepancy between FTXM and solid-phase bead assays. Demonstration of type B substances on donor T lymphocytes is necessary before absolute test validity is confirmed. Conclusion: False-positive FTXM may be associated with type B antibodies bound to T lymphocytes when a blood type O recipient receives tissue from a type B donor. This phenomenon explains the false-positive FTXM observed in the setting of ABO-incompatible kidney transplantation.

    英語, 研究論文(学術雑誌), BACKGROUND: Our aim was to characterize the motions of multiple laparoscopic surgical instruments among participants with different levels of surgical experience in a series of wet-lab training drills, in which participants need to perform a range of surgical procedures including grasping tissue, tissue traction and dissection, applying a Hem-o-lok clip, and suturing/knotting, and digitize the level of surgical competency. METHODS: Participants performed tissue dissection around the aorta, dividing encountered vessels after applying a Hem-o-lok (Task 1), and renal parenchymal closure (Task 2: suturing, Task 3: suturing and knot-tying), using swine cadaveric organs placed in a box trainer under a motion capture (Mocap) system. Motion-related metrics were compared according to participants' level of surgical experience (experts: 50 ≤ laparoscopic surgeries, intermediates: 10-49, novices: 0-9), using the Kruskal-Wallis test, and significant metrics were subjected to principal component analysis (PCA). RESULTS: A total of 15 experts, 12 intermediates, and 18 novices participated in the training. In Task 1, a shorter path length and faster velocity/acceleration/jerk were observed using both scissors and a Hem-o-lok applier in the experts, and Hem-o-lok-related metrics markedly contributed to the 1st principal component on PCA analysis, followed by scissors-related metrics. Higher-level skills including a shorter path length and faster velocity were observed in both hands of the experts also in tasks 2 and 3. Sub-analysis showed that, in experts with 100 ≤  cases, scissors moved more frequently in the "close zone (0  ≤ to < 2.0 cm from aorta)" than those with 50-99 cases. CONCLUSION: Our novel Mocap system recognized significant differences in several metrics in multiple instruments according to the level of surgical experience. "Applying a Hem-o-lok clip on a pedicle" strongly reflected the level of surgical experience, and zone-metrics may be a promising tool to assess surgical expertise. Our next challenge is to give completely objective feedback to trainees on-site in the wet-lab.

    英語, 研究論文(学術雑誌), BACKGROUND: Recurrence of SRNS is a major challenge in KT. Several clinical factors, including initial steroid sensitivity, have been associated with increased post-transplant SRNS recurrence risk. However, conflicting data have been reported, possibly due to the heterogeneous pathophysiology of SRNS and the lack of genetic testing of SRNS patients. Furthermore, the response to immunosuppressive therapies has not been evaluated. METHODS: Seventy patients aged 1-15 years at SRNS onset who underwent KT between 2002 and 2018 were enrolled. Patients with secondary, familial, syndromic, and genetic forms of SRNS and those who were not treated with steroid were excluded. This study aimed to assess the risk factors for post-transplant recurrence, including treatment responses to initial steroid therapy and additional therapies with immunosuppressive agents, rituximab, plasmapheresis, and/or LDL-A. RESULTS: Data from 36 kidney transplant recipients were analyzed. Twenty-two (61%) patients experienced post-transplant SRNS recurrence, while 14 patients did not. The proportion of patients who achieved complete or partial remission with initial steroid therapy and/or additional therapies with immunosuppressive agents, rituximab, plasmapheresis, and/or LDL-A was significantly higher in the SRNS recurrence group (19/22, 86%) than in the group without SRNS recurrence (6/14, 43%; p = .01). CONCLUSION: This study suggests that the response to steroid treatment, other immunosuppressive agents, rituximab, plasmapheresis, and/or LDL-A may predict post-transplant SRNS recurrence.

    英語, 研究論文(学術雑誌), BACKGROUND: Simultaneous pancreas and kidney transplantation (SPK) is a treatment option for patients with end-stage renal disease due to type 1 diabetes mellitus. We report a patient with a refractory fistula due to leakage from the duodenal stump of the pancreas graft after an SPK with bladder drainage who was successfully treated with a percutaneous direct injection of N-butyl-2-cyanoacrylate (NBCA). CASE PRESENTATION: A 60-year-old female with a 33-year history of type 1 diabetes mellitus and a 10-year history of renal replacement therapy underwent an SPK in 2015. At the time of transplantation, an abdominal aortic aneurysm with a high risk of rupture was treated by a Y-graft replacement prior to the SPK. Bladder drainage of the pancreas graft was chosen to avoid a vessel graft infection. The patient's postoperative course was uneventful. The patient was discharged on postoperative day 93 with good-functioning pancreas and kidney grafts. One and a half years after the operation, the patient was found to have acute graft pancreatitis and a leak from the duodenal stump of the pancreas graft due to a paralytic neurogenic bladder. The insertion of an indwelling catheter into the bladder and the endoscopic-guided insertion of a catheter into the graft pancreatic duct through the duodenum/bladder anastomosis did not result in the closure of the fistula. Therefore, NBCA was injected at the site of the leak point using CT-guided technique. The fistula was completely closed immediately after the injection, with no recurrences of leaks. CONCLUSIONS: A percutaneous direct injection of NBCA is one of the treatment options to treat intractable fistulas.

    英語, 研究論文(学術雑誌), BACKGROUND: Introduction of rituximab in the desensitization protocols for ABO-incompatible (ABOI) kidney transplantation (KTX) has afforded excellent results. However, the acceptability of minimal dosage of rituximab in these protocols remains to be defined. METHODS: Sixty-three patients who underwent ABOI KTX were included in this study. The desensitization protocol consisted of plasmapheresis, tacrolimus, mycophenolate mofetil, methylprednisolone, intravenous immunoglobulin, basiliximab, and low-dose rituximab (100 mg/body). We evaluated the efficacy, safety, and long-term outcome of this protocol (group R, n = 39) and compared them with those of patients who underwent splenectomy (group S, n = 24). RESULTS: Graft and patient survival at 10 years after KTX were comparable between the groups (94.4% [group R] vs 95.4% [group S] and 94.6% [group R] vs 95.8% [group S], respectively). The incidence of acute antibody-mediated rejection (AAMR) was similar in the 2 groups (10.2% vs 12.5%). There were no significant differences in the incidence of chronic active antibody-mediated rejection. Of the patients, 7 developed AAMR and 3 of these patients (1 in group R and 2 in group S) lost their grafts. There were no significant differences in the incidence of chronic active antibody-mediated rejection. The incidence of postoperative cytomegalovirus infection in group R was significantly lower than that in group S. Furthermore, the incidence of postoperative late-onset neutropenia was low in group R. CONCLUSIONS: A low-dose rituximab regimen for ABOI KTX is acceptable for preventing AAMR with a low incidence of delayed adverse events.

    Pediatric transplantation, 25, 5, e13971, 2021年01月20日, [国際誌]
    英語, BACKGROUND: ILNEB constitute an autosomal recessive disorder caused by homozygous or compound heterozygous mutation of the gene for the ITGA3. To date, 8 ILNEB patients have been reported, but all 6 neonatal-onset ILNEB patients suffered early death within 2 years. The most common cause of death among previously reported ILNEB patients was exacerbation of the respiratory condition. METHODS: In this study, we describe a case of ILNEB with neonatal onset in a female patient and the genetic and histopathological testing performed. RESULTS: Our patient had a compound heterozygous mutation in ITGA3. Compared to previously reported patients, this patient exhibited milder clinical and histopathological characteristics. After experiencing a life-threatening respiratory infection at 8 months old, the patient started periodic subcutaneous immunoglobulin treatment once every 1-2 weeks for nephrotic-range proteinuria-induced secondary hypogammaglobulinemia. At the age of 3 years, proteinuria gradually increased with severe edema despite strict internal management. Therefore, our patient underwent unilateral nephrectomy and insertion of a peritoneal dialysis catheter followed by another unilateral nephrectomy. One month later, she underwent an ABO-compatible living-donor kidney transplantation at the age of 4 years. CONCLUSIONS: Our patient is a neonatal-onset ILNEB patient who survived for more than 2 years and underwent successful kidney transplantation.

    英語, Introduction: Femoral nerve palsy is a rare but serious complication of kidney transplantation. We report a case of femoral nerve palsy following kidney transplantation and conduct a review of the literature on this complication. Case presentation: A 35-year-old woman with end-stage kidney disease, underwent kidney transplantation in the right iliac fossa. The day after the transplantation, she could not straighten her right leg. Physical examination revealed a paresis of her right quadriceps muscle. The patient's sensation of her right thigh was also impaired. We diagnosed her with femoral nerve palsy caused by inappropriate compression from a self-retaining retractor. Rehabilitation was started immediately. The patient's motor weakness gradually improved, and the patient became able to walk independently 4 weeks later. However, the patient's neuropathic pain sustained 6 months after her kidney transplantation. Conclusion: The improper use of self-retaining retractors can lead to femoral nerve palsy in patients undergoing kidney transplantation.

    英語, 研究論文(学術雑誌), OBJECTIVES: To develop a wet laboratory training model for learning core laparoscopic surgical skills and evaluating learners' competency level outside the operating room. METHODS: Participants completed three tasks (task 1: tissue dissection around the aorta; task 2: tissue dissection and division of the renal artery; task 3: renal parenchymal closure). Each performance was video recorded and subsequently evaluated by two experts, according to the Global Operative Assessment of Laparoscopic Skills and task-specific metrics that we developed (Assessment Sheet of Laparoscopic Skills in Wet Lab score). Mean scores were used for analyses. The subjective mental workload was also assessed (NASA Task Load Index). RESULTS: The 54 participants included 32 urologists, eight young trainees and 14 medical students. A total of 13 participants were categorized as experts (≥50 laparoscopic surgeries), eight as intermediates (10-49) and 33 as novices (0-9). There were significant differences in the Global Operative Assessment of Laparoscopic Skills and Assessment Sheet of Laparoscopic Skills in Wet Lab scores among the three groups in all three tasks. Higher NASA Task Load Index scores were observed in novices, and there were significant differences in tasks 1 (Kruskal-Wallis test, P = 0.0004) and 2 (P = 0.0002), and marginal differences in task 3 (P = 0.0745) among the three groups. CONCLUSIONS: Our training model has good construct validity, and differences in the NASA Task Load Index score reflect previous laparoscopic surgical experiences. Our findings show the ability to assess both laparoscopic surgical skills and mental workloads, which could help educators comprehend trainees' level outside the operating room. Given the decreasing opportunity to carry out pure laparoscopic surgeries because of the dissemination of robotic surgery, especially in urology, our model can offer practical training opportunities.
  • Increased urinary exosomal SYT17 levels in chronic active antibody-mediated rejection after kidney transplantation via the IL-6 amplifier.

    英語, 研究論文(学術雑誌), Chronic active antibody-mediated rejection (CAAMR) is a particular problem in kidney transplantation (KTx), and ~25% of grafts are lost by CAAMR. Further, the pathogenesis remains unclear, and there is no effective cure or marker. We previously found that a hyper NFκB-activating mechanism in non-immune cells, called the IL-6 amplifier, is induced by the co-activation of NFκB and STAT3, and that this activation can develop various chronic inflammatory diseases. Here, we show that synaptotagmin-17 (SYT17) is increased in an exosomal fraction of the urine from CAAMR patients, and that this increase is associated with activation of the IL-6 amplifier. Immunohistochemistry showed that SYT17 protein expression was increased in renal tubule cells of the CAAMR group. While SYT17 protein was not detectable in whole-urine samples by western blotting, urinary exosomal SYT17 levels were significantly elevated in the CAAMR group compared to three other histology groups (normal, interstitial fibrosis and tubular atrophy, and calcineurin inhibitors toxicity) after KTx. On the other hand, current clinical laboratory data could not differentiate the CAAMR group from these groups. These data suggest that urinary exosomal SYT17 is a potential diagnostic marker for CAAMR.

    英語, 研究論文(学術雑誌), BACKGROUND: Cytomegalovirus (CMV) infection is one of the major factors that affect morbidity and mortality in kidney transplant (KTx) patients. The rate of CMV seropositivity in children before KTx is lower than that in adults; therefore, pediatric KTx patients have a higher risk of CMV infection. In Japanese pediatric KTx patients, preemptive therapy for CMV infection is a main conventional therapy. This study investigated whether this preemptive treatment would affect kidney function at 2 years post-KTx. METHODS: A total of 163 patients, that is approximately half of the Japanese pediatric KTx patients nationwide, were recruited to participate in our study. We compared the values of the sequential estimated glomerular filtration rate (eGFR) at two years post-KTx and other influencing factors in CMV viremia, CMV disease, and no-infection groups. RESULTS: Cytomegalovirus infection after KTx occurred in 75 patients (46.0%), 38.7% of whom developed CMV disease. The sequential eGFR values post-KTx did not differ significantly between the three groups. CMV infection was not significantly correlated with other factors, other infections (including Epstein-Barr [EB] virus infection), acute rejection (AR), or adverse events. Only prolonged duration of total hospitalization was significantly associated with CMV infection (P = .002). In the multivariate analysis, younger age, CMV infection, and adverse effects were independently significantly related to prolonged total hospitalization. CONCLUSION: Preemptive therapy for CMV infection evidenced by viremia and disease did not significantly influence kidney function in Japanese pediatric KTx patients at two years after the operation.

One reason is that current diagnostics and therapeutics for chronic allograft rejection are very limited. We here show that enhanced NFκB signaling in kidney grafts contributes to chronic active antibody-mediated rejection (CAAMR), which is a major pathology of chronic kidney allograft rejections. Moreover, we found that urinary orosomucoid 1 (ORM1) is a candidate marker molecule and therapeutic target for CAAMR. Indeed, urinary ORM1 concentration was significantly higher in kidney transplant recipients pathologically diagnosed with CAAMR than in kidney transplant recipients with normal histology, calcineurin inhibitor toxicity, or interstitial fibrosis and tubular atrophy. Additionally, we found that kidney biopsy samples with CAAMR expressed more ORM1 and had higher NFκB and STAT3 activation in tubular cells than samples from non-CAAMR samples. Consistently, ORM1 production was induced after cytokine-mediated NFκB and STAT3 activation in primary kidney tubular cells. The loss- and gain-of-function of ORM1 suppressed and promoted NFκB activation, respectively. Finally, ORM1-enhanced NFκB-mediated inflammation development in vivo. These results suggest that an enhanced NFκB-dependent pathway following NFκB and STAT3 activation in the grafts is involved in the development of chronic allograft rejection after kidney transplantation and that ORM1 is a non-invasive candidate biomarker and possible therapeutic target for chronic kidney allograft rejection.

    英語, 研究論文(学術雑誌), Background: Virtual reality simulators allow trainees to perform repeated practice and provide objective dexterity metrics regarding their performance, which means that virtual reality-based surgical training is becoming a vital part of initial learning of basic laparoscopic surgical skills. However, its educational role in learning advanced procedures remains undetermined. We evaluated the validity of the laparoscopic radical nephrectomy module of the LapVision virtual reality simulator. Methods: Urologists, medical students, and a junior resident voluntarily participated in the present study, and they performed training with a laparoscopic left radical nephrectomy module. For construct validation, dexterity metrics calculated in the simulator and the mean score of Global Operative Assessment of Laparoscopic Skills evaluated by 2 experts' video review were compared according to the certification of Japanese Endoscopic Surgical Skill Qualification or previous surgical experience. Results: Ten experts (≥ 50 laparoscopic surgeries), 9 intermediates (11-49), and 14 novices (0-10) voluntarily participated in the present study. Regarding the construct validity, there was a significant difference in the total number of errors, blood loss, and Global Operative Assessment of Laparoscopic Skills score among the groups for both the Endoscopic Surgical Skill Qualification status and previous surgical experience. Conclusion: The present study demonstrated good construct validity for the LapVision nephrectomy module. Furthermore, global skill assessment was possible by experts' reviews, which indicates the usefulness of the virtual reality procedural module as a skill assessment tool. Virtual reality-based procedural simulation has marked potential to become a vital part of integrated laparoscopic training programs.

    Transplantation proceedings, 51, 5, 1382, 1386, 2019年06月, [査読有り], [国際誌]
    英語, BACKGROUND: Rituximab (RIT) is effective as a part of the desensitization therapy before ABO-incompatible kidney transplantation (ABOi-KTx), and a single dose of RIT at 375 mg/m2 or less is recommended. However, adequate RIT dose recommendations have not yet been established for individual recipients. Therefore, we evaluated the relationship between the proportion of B cells in peripheral blood and acute antibody-mediated rejection (AAMR). METHODS: Forty-four consecutive ABOi-KTx recipients were enrolled in this retrospective study. Before transplantation, subjects were treated with RIT at various doses, ranging from 65 to 400 mg/body (46-263 mg/m2), followed by plasmapheresis and intravenous immunoglobulin as a desensitization therapy. The percentage of CD19+ cells in the total peripheral blood lymphocytes population (%CD19) was determined the day before transplantation. Transplant recipients were divided into 2 groups according to pretransplant %CD19, as follows: low %CD19 group, ≤ 1.2% (n = 35) and high %CD19 group, > 1.2% (n = 9). The relationship between %CD19 and incidence of AAMR was evaluated, and the predicting factors for AAMR incidence were determined by univariate and multivariate analyses. RESULTS: The incidence of AAMR was significantly higher in the high %CD19 group than in the low %CD19 group (44.4% vs 5.7%, P = .006). Furthermore, multivariate analysis showed that %CD19 > 1.2% was the only independent factor to predict AAMR, with an odds ratio of 14.31 (P = .038). CONCLUSION: High %CD19 values after rituximab administration in ABOi-KTx recipients implies insufficient depletion of B cells, which can lead to AAMR.

    英語, 研究論文(学術雑誌), BACKGROUND: Multiple renal arteries are found in approximately 20% of living donor kidneys. We have been using an accessory artery cutoff diameter of 2 mm on preoperative computed tomography angiography to determine whether to sacrifice or reconstruct the artery. In this study, we assessed the validity and feasibility of this cutoff value. METHODS: Living related kidney recipients from 2005 to 2013 were enrolled in this retrospective study. The diameter of the accessory artery and adverse events were evaluated. The lost parenchymal volume (%) due to vascular obstruction or branch ligation was calculated by computed tomography volumetry. RESULTS: Among 128 kidney transplants, 30 donor kidneys had multiple arteries. Accessory arteries were reconstructed in 18 cases and intentionally ligated in 12 cases (mean diameter of accessory arteries, 3.10 [SD, 0.75] mm and 1.81 [SD, 0.28] mm, respectively). The mean estimated glomerular filtration rate at 1 or 12 months after transplant was not significantly different between the groups. Among reconstructed cases, 14 cases (77.8%) had good patency in the reconstructed arteries whereas the other 4 had vascular complications. The percentage of lost parenchymal volume due to ligation or occlusion of the reconstructed artery (calculated in 16 cases) was predictable with the following formula: lost volume (%) = 9.09 × diameter (mm) - 10.5 (P= .03, rs= 0.533 by Spearman rank correlation coefficient). This formula indicated that ligation of a 2-mm accessory artery leads to 7.68% loss of the renal parenchyma. CONCLUSIONS: Reconstruction using a cutoff diameter of 2 mm is worth attempting in terms of the success rate and graft function. Sacrifice of a 2-mm accessory artery leads to parenchymal loss of <8%.

    英語, 研究論文(学術雑誌), BACKGROUND: We recently reported anti-CD40 monoclonal antibody and rapamycin (aCD40/rapa) to be a reliable, nontoxic, immunosuppressive regimen for combined islet and kidney transplantation (CIKTx) in nonhuman primates. In the current study, we attempted to induce allograft tolerance through the mixed chimerism approach using a conditioning regimen with aCD40 and belatacept (Bela). METHODS: Five CIKTx or kidney transplant alone recipients were treated with aCD40/rapa for 4 months. All recipients then received a conditioning regimen including horse antithymocyte globulin and aCD40/Bela. The results were compared with previous reports of recipients treated with Bela-based regimens. RESULTS: All 3 CIKTx recipients developed mixed chimerism, which was significantly superior to that observed in the previous Bela-based studies. Nevertheless, all CIKTx recipients in this study lost their islet and renal allografts as a result of cellular and humoral rejection on days 140, 89, and 84. The 2 kidney transplant-alone recipients were treated with the same conditioning regimen and suffered rejection on days 127 and 116, despite the development of excellent chimerism. B lymphocyte reconstitution dominated by memory phenotypes was associated with early development of donor-specific antibodies in 4 of 5 recipients. In vitro assays showed no donor-specific regulatory T cell expansion, which has been consistently observed in tolerant recipients with our mixed chimerism approach. CONCLUSIONS: Despite displaying excellent immunosuppressive efficacy, costimulatory blockade with anti-CD40 monoclonal antibody (2C10R4) may inhibit the induction of renal or islet allograft tolerance via a mixed chimerism approach.

    英語, 研究論文(学術雑誌), INTRODUCTION: Laparoscopic surgery has been a standard procedure of living donor nephrectomy (LDN). Transperitoneal hand-assisted laparoscopic LDN (HALDN) has been commonly reported by many centers with excellent outcome. However, there are few studies reporting retroperitoneoscopic LDN (RPLDN). MATERIALS AND METHODS: Four hundred four consecutive kidney donors (124 men, 280 women) were enrolled in this study. Age of the donors was 55.0 ± 10.7 years. RPLDN was performed for 294 donors, and HALDN for 110 donors. We compared perioperative donor outcome and early complication rates between RPLDN and HALDN to evaluate the safety and efficacy of RPLDN. RESULTS: Intraoperative blood loss was significantly less in RPLDN than in HALDN (p < 0.05). The conversion rate to open surgery was similar between the two groups. The intraoperative complication rate was 1.0% (two vascular injuries and one bowel injury) in RPLDN and 0.9% (one vascular injury) in HALDN. The postoperative complication rate was 3.4% (six surgical site infections, two postoperative bleeding, one colon perforation, one ileus, one rhabdomyolysis) in RPLDN and 1.8% (two surgical site infections) in HALDN. Although warm ischemic time was significantly longer in RPLDN than in HALDN (p < 0.01), the incidence of delayed graft function was similar between the two groups. Furthermore, there was no difference in 1-year graft survival between the two groups. CONCLUSIONS: Both RPLDN and HALDN procedures were well tolerated with minimal complication rates, and both procedures showed similar impact on recipient graft function. These results suggest that RPLDN could be a feasible option for LDN as well as HALDN.

    英語, 研究論文(学術雑誌), BACKGROUND: We have previously reported successful induction of renal allograft tolerance in nonhuman primates (NHP) after an initial posttransplant period of conventional immunosuppression (delayed tolerance) using a nonmyeloablative conditioning regimen consisting of anti-CD154 and anti-CD8 mAbs plus equine antithymocyte globulin (Atgam) and donor bone marrow transplantation (DBMT). Because these reagents are not currently clinically available, the protocol was revised to be applicable to human recipients of deceased donor allografts. METHOD: Four cynomolgus monkeys received major histocompatibility complex-mismatched kidney allografts with conventional immunosuppression for 4 months. The recipients were then treated with a nonmyeloablative conditioning regimen consisting of thymoglobulin, belatacept, and DBMT. The results were compared with recipients treated with conditioning regimen consisting of Atgam and anti-CD154 mAb, with and without anti-CD8 mAb. RESULTS: In 4 consecutive NHP recipients treated with the modified conditioning regimen, homeostatic recovery of CD8 TEM was delayed until after day 20 and multilineage chimerism was successfully induced. Three of the 4 recipients achieved long-term allograft survival (>728, >540, >449 days) without ongoing maintenance immunosuppression. Posttransplant MLR showed loss of antidonor CD8 T cell and CD4 IFNγ responses with expansion of CD4FOXP3 regulatory T cells. However, the late development of donor-specific antibody in NHP recipients confirms the need for additional anti-B-cell depletion with agents, such as rituximab, as has been shown in our clinical trials. CONCLUSIONS: This study provides proof of principle that induction of mixed chimerism and long-term renal allograft survival without immunosuppression after delayed DBMT is possible with clinically available reagents.

    英語, 研究論文(学術雑誌), Successful induction of allograft tolerance has been achieved in nonhuman primates (NHPs) and humans via induction of transient hematopoietic chimerism. Since allograft tolerance was achieved in these recipients without durable chimerism, peripheral mechanisms are postulated to play a major role. Here, we report our studies of T cell immunity in NHP recipients that achieved long-term tolerance versus those that rejected the allograft (AR). All kidney, heart, and lung transplant recipients underwent simultaneous or delayed donor bone marrow transplantation (DBMT) following conditioning with a nonmyeloablative regimen. After DBMT, mixed lymphocyte culture with CFSE consistently revealed donor-specific loss of CD8+ T cell responses in tolerant (TOL) recipients, while marked CD4+ T cell proliferation in response to donor antigens was found to persist. Interestingly, a significant proportion of the proliferated CD4+ cells were FOXP3+ in TOL recipients, but not in AR or naive NHPs. In TOL recipients, CD4+FOXP3+ cell proliferation against donor antigens was greater than that observed against third-party antigens. Finally, the expanded Tregs appeared to be induced Tregs (iTregs) that were converted from non-Tregs. These data provide support for the hypothesis that specific induction of iTregs by donor antigens is key to long-term allograft tolerance induced by transient mixed chimerism.

    英語, 研究論文(学術雑誌), Mixed chimerism discovered in Freemartin cattle by Ray Owen 70 years ago paved the way for research on immune tolerance. Since his discovery, significant progress has been made in the effort to induce allograft tolerance via mixed chimerism in various murine models. However, induction of persistent mixed chimerism has proved to be extremely difficult in major histocompatibility complex mismatched humans. Chimerism induced in humans tends to either disappear or convert to full donor chimerism, depending on the intensity of the conditioning regimen. Nevertheless, our studies in both NHPs and humans have clearly demonstrated that renal allograft tolerance can be induced by transient mixed chimerism. Our studies have shown that solid organ allograft tolerance via transient mixed chimerism 1) requires induction of multilineage hematologic chimerism, 2) depends on peripheral regulatory mechanisms, rather than thymic deletion, for long-term maintenance, 3) is organ specific (kidney and lung but not heart allograft tolerance are feasible). A major advantage of tolerance induction via transient mixed chimerism is exclusion of the risk of graft-versus-host disease. Our ongoing studies are directed toward improving the consistency of tolerance induction, reducing the morbidity of the conditioning regimen, substituting clinically available agents, such as Belatacept for the now unavailable anti-CD2 monoclonal antibody, and extending the protocol to recipients of deceased donor allografts.

    英語, 研究論文(学術雑誌), BACKGROUNDS: The deep inferior epigastric artery (DIEA), which feeds the lower rectus abdominis muscle (lower RAM), is usually transected in kidney transplantation. In this study, we investigated whether preservation of DIEA can prevent lower RAM atrophy. METHODS: Two hundred and forty-five kidney transplant recipients (150 men and 95 women) were enrolled in the study (mean age 39.9 years) and were divided into two groups according to whether DIEA was transected (group A, n = 175) or preserved (group B, n = 70). The extent of lower RAM atrophy calculated in computed tomography (performed 1 year after transplantation) and incidence of lower RAM atrophy were compared between the two groups. The most predictive factors for lower RAM atrophy were assessed using a multivariate logistic regression model. RESULTS: The extent of lower RAM atrophy was significantly lower in group B (15.0 ± 18.5%) than that in group A (38.9 ± 25.4%, P = 0.003). The incidence of lower RAM atrophy was less prevalent in group B (20.0%) compared with that in group A (62.9%, P < 0.001). The sacrifice of DIEA was the only independent predictive factor for lower RAM atrophy (P < 0.001). CONCLUSIONS: Preservation of DIEA during kidney transplant can prevent lower RAM atrophy.

    腎移植後の長期成績の向上にはカルシニューリン阻害薬(CNI)による慢性腎毒性の克服が必要である。これまでのCNI腎毒性の概念は腎細動脈の中膜平滑筋の硝子様変化による血管毒性とされており、これにより腎の間質線維化や尿細管委縮が始まり移植腎機能低下を起こすと考えられていた。この動脈硝子化に代表される血管内皮細胞変化が慢性腎毒性のマーカーとされてきたが、尿細管や間質の上皮細胞系に注目したマーカーが必要である。
    近年CNIによる炎症性サイトカインの産生の誘導が指摘されており、慢性炎症のメカニズムのひとつであるNF-κB経路とSTAT3経路の活性化が相乗的に起こる炎症増幅回路の活性化が関与している可能性がある。一方で、免疫抑制剤の一つであるステロイドには抗炎症作用があり、CNIよる炎症性サイトカイン産生誘導を抑制している可能性がある。よって本研究の目的は尿細管間質においてCNI腎毒性をステロイドが軽減しているかを検索し、さらに新規バイオマーカーの開発に取り組むことである。
    まずステロイドがCNIによる腎毒性に良い影響を及ぼすかを臨床データおよび経時的な移植腎組織より解析した。当院の腎移植患者でステロイドが継続されている群と、ステロイドを早期に中止した群で、移植腎サンプルの見直しを行った。Periodic acid-Schiff stain(PAS)染色を用いて、これらの細動脈の硝子化を国際基準であるBanff分類のAlternate quantitative scoring for Hyaline Arteriolar Thickening(aahスコア)で3段階に分けて評価した。現段階でステロイド中止群においてCNI毒性が有意に高い結果がでている。この結果はステロイドが慢性腎毒性を抑制する可能性を示す重要な知見である。

    腎移植の短期成績は飛躍的に向上しているが、長期的にはドナー特異的抗体による慢性抗体関連型拒絶反応(CAAMR)により移植腎機能廃絶となる症例が多く、この克服が長期成績の向上に必要不可欠である。しかし、CAAMRに対する有効な治療法は未だ確立していない。当研究の目的は、CAAMRとなりうる患者を早期に発見する診断法を開発することである。当研究は3つからなり令和3年度の研究実績は以下の通りである。
    1. パラフィン移植腎生検標本を用いたCAAMR関連遺伝子の検索:腎機能が正常である患者において移植後1年目、2年目に行ったプロトコール移植腎生検を用いて遺伝子解析した。結果炎症に関連する数種類の遺伝子の発現を組み合わせることにより5年目にCAAMRに至る症例と至らない症例との区別がつく可能性を見いだせた。
    2.CAAMR早期診断のための尿中バイオマーカーの検索:過去に報告した尿中ORM1とSYT17の他に数種類の遺伝子候補について解析中である。
    3.末梢血リンパ球反応による早期診断法の開発: 200症例につきCFSE/MLR assayを行った結果、腎機能が正常で病理学的にも問題ない患者においてはドナーに対するCD8陽性T細胞の反応は認めないが、CAAMRの患者ではドナーに対するCD8陽性T細胞の強い反応が認めた。また、CD4に関しても同様の所見を認めたが、その中でもTh1,Th17細胞の反応が強く見られた。また、抗ドナー抗体が陽性で腎生検で拒絶を認めない、前CAMR状態の患者においてもCAMRの患者と同様の反応を認めた。CFSE/MLR assayによりCAAMRが未然に診断できる可能性を見いだせた。

    腎移植の短期成績は飛躍的に向上しているが、長期的にはドナー特異的抗体による慢性抗体関連型拒絶反応(CAAMR)により移植腎機能廃絶となる症例が多く、この克服が長期成績の向上に必要不可欠である。しかし、CAAMRに対する有効な治療法は未だ確立していない。当研究では、CAAMRとなりうる患者を早期に発見する診断法を開発することを目的とした。
    混合リンパ球反応試験(MLR)はT細胞のドナーに対する反応を測定する方法で、急性拒絶反応をモニタリングする方法として報告されてきた。本研究では、はじめてCAAMRをモニタリングし、CAAMR発症を予測できる可能性を持つMLRを開発できた。

    本研究においてはMM eplet数の多寡のみでは移植腎予後に明らかな影響を認められず、その理由としては十分な症例数が集まらなかったこと、観察期間が十分でなかったこと、両施設ともに免疫抑制プロトコールが年代によって変遷しており同じ条件での比較ができていないことにあると思われた。また、日本人という比較的HLA多様性の少ない国民ではMM eplet数の多様性も少なく、これのみで差が出づらい可能性も考えられた。
    今後は、諸家の報告によるMM eplet数のリスク評価を元にしてCAMRのリスク階層化を行い、それに従った免疫抑制プロトコールの使い分けを行い、前向き研究を立ち上げるべく研究の準備を行っている。
