BACKGROUND: A link between IgA nephropathy and Crohn's disease has recently been reported. Other researchers hypothesize that intestine-derived IgA complexes deposit in glomerular mesangial cells, eliciting IgA nephropathy. Intestinal mucosal plasma cells mainly secrete IgA2. Nevertheless, IgA1 deposition is strongly implicated as being the primary cause of IgA nephropathy. CASE PRESENTATION: A 46-year-old Japanese man developed IgA nephropathy 29 years ago, following tonsillectomy. As a result, a normal urinalysis was obtained. The patient previously suffered Crohn's disease followed by urinary occult blood and proteinuria six years ago. Exacerbation of IgA nephropathy was highly suspected. Therefore a renal biopsy was performed. A diagnosis of exacerbation of IgA nephropathy with mesangial cell proliferation and fibrotic cellular crescent was based upon the pathological findings. The patient exhibited a positive clinical course and eventually achieved a remission with immunosuppressive therapy including prednisolone treatment. Immunostaining for the detection of IgA subtypes was performed on both of his kidney and excised ileum. The results revealed IgA1 and IgA2 deposition by submucosal cells in intestine. Furthermore, IgA1 deposition of mesangial areas in the patient's kidney, indicated an association of IgA1 with the exacerbation of IgA nephropathy. CONCLUSION: This case represents the possibility that the intestine-derived IgA1 can be the origin of galactose-deficient IgA which is known to cause IgA nephropathy exacerbation.

OBJECTIVE: Angiotensin II (AngII) infusion profoundly increases activity of calpains, calcium-dependent neutral cysteine proteases, in mice. Pharmacological inhibition of calpains attenuates AngII-induced aortic medial macrophage accumulation, atherosclerosis, and abdominal aortic aneurysm in mice. However, the precise functional contribution of leukocyte-derived calpains in AngII-induced vascular pathologies has not been determined. The purpose of this study was to determine whether calpains expressed in bone marrow (BM)-derived cells contribute to AngII-induced atherosclerosis and aortic aneurysms in hypercholesterolemic mice. APPROACH AND RESULTS: To study whether leukocyte calpains contributed to AngII-induced aortic pathologies, irradiated male low-density lipoprotein receptor(-/-) mice were repopulated with BM-derived cells that were either wild-type or overexpressed calpastatin, the endogenous inhibitor of calpains. Mice were fed a fat-enriched diet and infused with AngII (1000 ng/kg per minute) for 4 weeks. Overexpression of calpastatin in BM-derived cells significantly attenuated AngII-induced atherosclerotic lesion formation in aortic arches, but had no effect on aneurysm formation. Using either BM-derived cells from calpain-1-deficient mice or mice with leukocyte-specific calpain-2 deficiency generated using cre-loxP recombination technology, further studies demonstrated that independent deficiency of either calpain-1 or -2 in leukocytes modestly attenuated AngII-induced atherosclerosis. Calpastatin overexpression significantly attenuated AngII-induced inflammatory responses in macrophages and spleen. Furthermore, calpain inhibition suppressed migration and adhesion of macrophages to endothelial cells in vitro. Calpain inhibition also significantly decreased hypercholesterolemia-induced atherosclerosis in the absence of AngII. CONCLUSIONS: The present study demonstrates a pivotal role for BM-derived calpains in mediating AngII-induced atherosclerosis by influencing macrophage function.

BMJ case reports 2016 10.1136/bcr-2016-214491 2016年4月

記述言語：英語掲載種別：研究論文（学術雑誌）

We report a case of a 20-year-old man presenting with acute painful blue fingers. All physical findings, including an Allen test, were normal, and systematic symptoms frequently seen in collagen diseases were absent. Although we performed a wide variety of investigations including medical imaging, no specific abnormal findings were observed. Skin biopsy pathology was an important reference. The patient's symptoms gradually improved and were completely resolved without specific treatment. Based on the clinical presentation and course, we gave a diagnosis of Achenbach's syndrome, developed in a young male. Achenbach's syndrome is rare, but still may be encountered in clinical practice. The symptoms can be startling to the patient, eliciting fear of something terrible when, in fact, the syndrome is relatively benign and has a good prognosis. Recognising this disease quickly after presentation helps to eliminate the anxiety of the patient, as well as reducing excessively invasive investigations. We present a case report to enlighten Achenbach's syndrome.

BACKGROUND AND AIMS: Chronic kidney disease (CKD) and diabetes mellitus (DM) are considered as risk factors for cardiovascular diseases. The purpose of this study was to clarify the relationship of CKD and DM with the presence of abdominal aortic aneurysm (AAA). METHODS: We enrolled 261 patients with AAA (AAA+) and age-and-sex matched 261 patients without AAA (AAA-) at two hospitals between 2008 and 2014, and examined the association between the risk factors and the presence of AAA. Furthermore, in order to investigate the prevalence of AAA in each group, we enrolled 1126 patients with CKD and 400 patients with DM. RESULTS: The presence of CKD in patients with AAA+ was significantly higher than that in patients with AAA- (AAA+; 65%, AAA-; 52%, P = 0.004). The presence of DM in patients with AAA+ was significantly lower than that in patients with AAA- (AAA+; 17%, AAA-; 35%, P < 0.001). A multivariate logistic regression analysis demonstrated that hypertension, ischemic heart disease and CKD were independent determinants, whereas, DM was a negatively independent determinant, for the presence of AAA. The prevalence of AAA in patients with CKD 65 years old and above was 5.1%, whereas, that in patients with DM 65 years old and above was only 0.6%. CONCLUSION: CKD is a positively associated with the presence of AAA. In contrast, DM is a negatively associated with the presence of AAA in Japanese population.

It has been reported that cyclosporine A (CsA) treatment may be associated with posterior reversible encephalopathy syndrome. We report a 16-year-old man who exhibited nephrotic syndrome and posterior reversible encephalopathy syndrome. Intensive antihypertensive therapy restored him to consciousness. Renal biopsy revealed that he suffered from focal segmental glomerulosclerosis. Although he was treated with prednisolone and low-density lipoprotein apheresis therapy, his proteinuria remained at high level. Then, mycophenolate mofetil (MMF) with less influence on vessel endothelium compared with CsA and tacrolimus was administered. Soon after, he reached remission of nephrotic syndrome without recurrence of posterior reversible encephalopathy syndrome. This is the first case that a young patient of focal segmental glomerulosclerosis with posterior reversible encephalopathy syndrome achieved a complete remission by MMF treatment without recurrence of posterior reversible encephalopathy syndrome. MMF may be effective for young patients of focal segmental glomerulosclerosis especially with clinical condition of vascular endothelial damage such as posterior reversible encephalopathy syndrome.

BACKGROUND: Vascular calcification contributes to cardiovascular disease in hemodialysis (HD) patients with diabetes. The randomized controlled trial reported here compared the effects of lanthanum carbonate (LC) and calcium carbonate (CC) on vascular stiffness assessed using brachial-ankle pulse wave velocity (ba-PWV), intima-media thickness (IMT), bone mineral density (BMD), and serum markers of chronic kidney disease - mineral and bone disorder in such patients. METHODS: Ba-PWV, IMT, BMD, and the biomarkers osteocalcin (OC) and bone alkaline phosphatase (BAP) were examined in 43 type 2 diabetes HD patients treated with LC (n=21) or CC (n=22) for 2 years. RESULTS: Forty-one patients completed the study (19, LC; 22, CC). The mean ba-PWV significantly increased only in the CC group (median: 2,280.5 to 2,402.5 cm/s, P<0.05), after 24-month treatment; it remained unchanged in the LC group (median: 1,830.5 to 2,018.3 cm/s). However, the difference between the groups did not reach statistical significance. Changes in IMT and BMD were not different between the two groups. Changes in serum phosphorus, corrected calcium, and intact parathyroid hormone levels were similar between the groups. The incidence of fracture was 0% (0/19) in the LC group, and 13.6% (3/22) in the CC group (P=0.2478). The OC/BAP ratio increased significantly in the LC group (median: 0.83 to 2.47), compared with in the CC group (median: 0.77 to 1.40) (P=0.036). CONCLUSION: From this study, in Japanese type 2 diabetes HD patients, we conclude that 2-year treatment with LC might have slowed the progression of ba-PWV; however, it did not cause a difference in ba-PWV, IMT, BMD, or fracture, compared with CC. Further, LC increased the OC/BAP ratio to a greater extent than CC.

A 71-year-old woman presented with a high-grade fever, neck pain, anemia and thrombocytopenia. After performing further examinations, we concluded that she had simultaneously developed large vessel vasculitis and myelodysplastic syndrome (MDS). Although glucocorticoid administration improved her clinical symptoms, the MDS transformed into acute myeloid leukemia and she died one year after receiving the diagnosis. The occurrence of immune-mediated disorders in patients with MDS is a well-known phenomenon; however, large vessel vasculitis is a rare complication of MDS. Our case suggests that the association between systemic vasculitis and MDS may result in poor outcomes.
