    Modern Rheumatology Case Reports 2022年08月09日 
    ABSTRACT Symptomatic vitamin C deficiency, scurvy, is a relatively rare disease in developed countries, but it has been reported in patients with autism spectrum disorder or developmental delay who tend to have selective diets. Patients with scurvy often demonstrate musculoskeletal manifestations with unknown pathophysiology. Herein, we report a case of scurvy in an 11-year-old boy who presented with iron-deficiency anaemia, systemic osteomyelitis, myositis predominantly in the lower extremities, and right ventricular volume overload with mild pulmonary hypertension and was diagnosed with scurvy. He had a mild developmental disorder and a selective diet, which resulted in severe vitamin C deficiency. He received intravenous and oral vitamin C supplementation, which relieved his arthralgia and muscle pain in a week. Following 4 months of vitamin C supplementation, he demonstrated no abnormal manifestations on laboratory or imaging examination and recovered without sequelae. Inflammatory cytokine and chemokine evaluations demonstrated elevated levels of interleukin (IL)-6, IL-17A, and IL-23, which are associated with T-helper (Th) 17 cell activation. This study is the first to suggest the association between the inflammation seen in scurvy, rheumatic manifestations in the patient, and Th17 cell activation. Further analysis of the association between the inflammation and vitamin C supplementation may contribute to new insights for the comprehension and treatment of other inflammatory diseases, such as rheumatic diseases.

    Abstract Background: Fibroblast growth factor 23 (FGF23) decreases serum phosphate levels by inhibiting proximal tubular phosphate reabsorption and intestinal phosphate absorption by decreasing serum 1,25-dihydroxyvitamin D level, thereby regulating phosphate metabolism. Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused by FGF23 overproduction by tumor tissue. Resecting the responsible tumor is a radical treatment for TIO. When the responsible tumor is undetectable, phosphate and active vitamin D administration is recommended. However, supplementation alone is frequently insufficient to maintain phosphate levels and it is difficult to prevent the complications associated with medical therapy, including hypercalciuria and nephrocalcinosis. Recently, burosumab, a human monoclonal anti-FGF23 antibody, has been approved in Japan as a therapeutic agent for FGF23-related hypophosphatemia. Here, we present a patient with TIO effectively treated with burosumab in the absence of identification of tumour location. Clinical case: A 47-year-old female developed pain and edema of the feet; however, the cause could not be determined at local hospitals. Afterwards, she developed marked bone atrophy in the feet and was referred to our hospital. Her age at symptom onset, hypophosphatemia (serum P, 1.9 mg/dl, 2.7 mg/dl < n < 4.6 mg/dl), high serum FGF23 level (630 pg/ml, 16 pg/ml < n < 69 pg/ml), and decreased 1,25-dihydroxyvitamin D level (12.9 pg/ml, 20 pg/ml < n < 60 pg/ml) indicated FGF23-related osteomalacia. She was not having any medication at the time of diagnosis, including saccharified iron oxide or iron polymaltose. Urinary phosphate excretion increased without renal tubular defect; therefore, hypophosphatemic osteomalacia was diagnosed. MRI showed high signal intensity in the talus, sacral, and L5 vertebral regions, indicating multiple pseudofractures. Comprehensive imaging studies, including systemic CT scan and 111In-pentetreotide scintigraphy, did not reveal any tumors despite the suspicion of TIO. Next, we performed systemic venous sampling, which revealed high FGF23 level in the left external iliac vein. Second venous sampling limited to the left lower limb exhibited high FGF23 level in the posterior tibial vein. However, an additional imaging study limited to the left foot could not identify any tumors. Genetic variation was negative for potentially responsible genes, including PHEX and FGF23. We decided to administer burosumab to normalize serum phosphate level without phosphate supplementation. Within 2 months, pain was relieved and the visual analog scale scores also improved from 10 to 6. Moreover, bone MRI showed improved pseudofractures. Conclusion: Burosumab administration was effective for TIO of unknown origin, and it improved not only laboratory findings but also clinical symptoms in this case.

    OBJECTIVE: Rapidly progressive interstitial lung disease (RPILD) is a major cause of death in patients with DM. Although clinically amyopathic DM (CADM) represents risk for RPILD, the incidence rate of RPILD in patients with CADM varies widely. Whole-body (WB) MRI can reveal involvement of systemic muscle and myofascia. The objective of this study was to explore the risk factors for RPILD in patients with DM using WB-MRI. METHODS: This retrospective study comprised 41 patients with DM who underwent WB-MRI before the initiation of treatment in our hospital. Muscular and myofascial signals were scored on 42 muscular groups. The myofascia/muscle ratio was calculated and used to define the relevance of myofascia-dominant involvement. RPILD was defined as worsening of dyspnoea, hypoxaemia and radiographic ILD/fibrosis within 3 months from the onset of respiratory symptoms. RESULTS: Among the 41 patients, 17 had CADM and 30 had ILD, including 10 patients with RPILD. All patients including those with CADM showed abnormal signal intensity in both muscle and myofascia (median score: 15 and 23, respectively). Muscle signal scores positively correlated with the serum creatine kinase level (r = 0.714; P< 0.001). Patients with RPILD showed a significantly higher myofascia/muscle ratio than those without RPILD (1.929 vs 1.200; P= 0.027). Logistic regression analysis identified higher myofascia/muscle ratio as independent risk factors for developing RPILD. CONCLUSION: Myofascia-dominant involvement was defined and appreciated in patients with DM using WB-MRI. This may be one of the risk factors for RPILD.

    PURPOSE: To evaluate heterogeneity of myocardial contraction in relation to extensive late gadolinium enhancement (LGE) in hypertrophic cardiomyopathy (HCM) patients with preserved left ventricular ejection fraction, using fast strain-encoded magnetic resonance imaging. MATERIALS AND METHODS: Twenty-two HCM patients and 24 age-matched control subjects were included in this retrospective study. The regional and global peak values of longitudinal and circumferential strain (LSregional, LSglobal, CSregional, CSglobal), and their regional heterogeneities were evaluated using coefficients of variation (LSCoV, CSCoV) in relation to LGE. Receiver operating characteristic curve analysis was performed to identify patients with a total left ventricular myocardial LGE ≥ 15%. RESULTS: LSglobal in HCM patients was significantly decreased compared to that in controls (- 14.4 ± 2.4% vs - 17.2 ± 2.0%; p = 0.0004), while CSglobal was not (p = 1.0). Negative LGE segments demonstrated decreased LSregional in HCM patients compared to in controls (p < 0.0001), while CSregional was not decreased. CSCoV demonstrated the largest area under the curve (AUC) (0.91), with high sensitivity (83%) and specificity (94%) for detection of HCM patients with extensive LGE, while the AUC of LSCoV was low (0.49). CONCLUSION: The heterogeneity in CSregional has a high diagnostic value for detection of HCM patients with extensive LGE.

    Objectives: To evaluate the scoring of whole-body magnetic resonance imaging (WBMRI) for efficacy assessment in rheumatoid arthritis (RA) patients receiving biological disease-modifying anti-rheumatic drugs (bDMARDs).Methods: Thirty consecutive RA patients receiving bDMARDs were included in this retrospective study. Contrast WBMRI was performed before and 1 year after bDMARDs initiation.Results: At baseline, mean age was 57.1 years and mean disease duration was 3.0 years. Median disease activity score in 28 joints improved from 5.1 to 2.1. Treatment with bDMARDs improved mean whole-body synovitis score from 31.2 to 23.2 and median whole-body bone-edema score from 11 to 3. Whole-body bone-erosion score improved in seven patients and deteriorated in 17 patients. Logistic regression analysis identified whole-body synovitis score as a poor prognostic factor for whole-body bone-erosion progression. Bone-edema score in individual bones was identified as a poor prognostic factor for the progression of bone-erosion. Changes in hand synovitis score correlated with those of other joints, but neither changes in bone-edema nor erosion score of hands correlated with those of other joints in WBMRI.Conclusions: WBMRI scoring may be a novel useful tool to evaluate the efficacy of anti-rheumatic drugs, as well as a potential predictor of joint prognosis, in patients with RA.

    Background:Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) is an ideal procedure in selected patients with benign or low-grade malignant tumors in the body/tail of the pancreas. We describe our procedure and experience with splenic vessel-preserving LSPDP (SVP-LSPDP) in a retrospective case series.Methods:Six consecutive patients underwent SVP-LSPDP from January 2011 to September 2013. We evaluated the courses of the splenic artery by preoperative computed tomography and applied an individualized approach (the superior approach or inferior approach) to the splenic artery.Results:All of the operations were successful. The median surgical duration was 249 minutes. The median blood loss was 0 mL. Pathologic examination revealed 4 cases of insulinoma, 1 case of solid pseudopapillary tumor, and 1 case of pancreatic metastasis from renal carcinoma.Conclusions:In performing SVP-LSPDP, it is effective to make a strategic choice between 2 different approaches according to the course of splenic artery.

    To determine whether the preoperative pancreatic apparent diffusion coefficient (ADC) can be used to predict the development of postoperative pancreatic anastomotic failure (PAF). We retrospectively examined the cases of 79 patients who underwent pancreatic head resection between January 2010 and October 2013. The patients underwent 1.5-T MR imaging including diffusion-weighted imaging before surgery. The main pancreatic duct diameter (MPD), the pancreatic parenchymal thickness (PT), and the ADC of the pancreatic remnant parenchyma were measured. Two radiologists blinded to the patients' outcomes performed the measurements. The imaging parameters were compared between the patients who developed PAF and those who did not. The cut-off ADC for the development of PAF was calculated with a receiver operating characteristic analysis. The imaging parameters were highly correlated between the two observers. The MPD and PT did not differ significantly among the patients. The mean pancreatic ADCs were significantly higher in the patients with PAF than in those without PAF. An ADC higher than 1.50 x 10(-3) mm(2)/s (Az = 0.719, observer-1) or 1.35 x 10(-3) mm(2)/s (Az = 0.752, observer-2) was optimal for predicting the development of postoperative PAF. Measuring the preoperative non-tumorous pancreatic ADC may be useful for the prediction of a postoperative PAF.
