Human glomerular diseases can be caused by several different diseases, many of which include mesangial expansion and/or proliferation followed by glomerulosclerosis. However, molecular mechanisms underlying the pathologic mesangial changes remain poorly understood. Here, we investigated the role of the mammalian target of rapamycin complex 1 (mTORC1)-S6 kinase pathway in mesangial expansion and/or proliferation by ablating an upstream negative regulator, tuberous sclerosis complex 1 (TSC1), using tamoxifen-induced Foxd1-Cre mice [Foxd1ER(+) TSC1 mice]...

BACKGROUND: The prevalence of chronic kidney disease (CKD) is increasing, leading to significant morbidity and mortality. Kidney biopsy remains the gold standard for diagnosing the underlying etiology of CKD, but the procedure carries complication risks. The aim of this study was to identify novel noninvasive biomarkers correlating with kidney function and histopathology in biopsy-proven CKD patients. METHODS: We profiled 2402 urinary microRNAs (miRNAs) to identify and confirm differentially expressed miRNAs associated with kidney function and histopathology in patients with diabetic nephropathy (n = 58) or lupus nephritis (n = 89), important etiologies of CKD, compared with healthy controls (n = 93 and 119, respectively)...

  In systemic lupus erythematosus (SLE), lupus nephritis (LN) is an important complication as an intractable condition and considered to be a prognostic factor. Based on the past reports that explain immunological functions of OPN and its relationship with autoimmune diseases such as LN or IgA nephropathy, we measured OPN full and OPN N-half in serum and urine of SLE patients and examined the possibility as a disease biomarker. OPN N-half is known as a more physiologically active form than OPN full. As a result, OPN N-half in urine was higher in LN than in healthy control, and also higher than in diabetic nephropathy that is a non-inflammatory nephropathy...

Background: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by multiple organ involvement. Lupus nephritis (LN) is a common manifestation with a wide variety of histological appearances. Matrix metalloproteinases (MMP) 2 and 9 are gelatinases capable of degrading glomerular basement membrane type IV collagen, which have been associated with LN. We examine the expression of MMP2 and MMP9 in different classes of LN. Methods: MMP2 and MMP9 expression was detected by immunohistochemistry in sections from renal biopsy specimens with class III, class IV and class V LN (total n = 31), crescentic immunoglobulin A nephropathy (n = 6), pauci-immune glomerulonephritis (n = 7), minimal change disease (n = 2), mesangiocapillary glomerulonephritis (n = 7), diabetic nephropathy (n = 12) and histologically normal controls (n = 8)...

BACKGROUND Sjögren's syndrome is an autoimmune disorder caused by the infiltration of monocytes in epithelial glandular and extra-glandular tissues. Hallmark presentations include mouth and eye dryness. Although renal involvement is uncommon in primary Sjögren's syndrome (pSS), patients may experience renal tubular acidosis type I (RTA I), tubulointerstitial nephritis, diabetes insipidus (DI), nephrolithiasis, and Fanconi syndrome. However, it is atypical to see more than 1 of these manifestations in a single patient...

Evaluation of hypoglycemia in a patient with known diabetes mellitus, although usually straightforward, can at times be challenging. We present the case of an 8 year-old Latina girl initially diagnosed with type 1 diabetes mellitus in the setting of multiple autoimmune disorders, including dermatomyositis and lupus nephritis. She subsequently developed signs of insulin resistance and severe hypoglycemia, which was found to be due to insulin-receptor autoantibodies. This condition, known as type B insulin resistance, is a rare, heterogeneous metabolic disease that may feature hypoglycemia in the setting of extreme insulin resistance and hyperinsulinemia and, in this case, masqueraded as type 1 diabetes mellitus...

During pregnancy, CKD increases both maternal and fetal risk. Adverse maternal outcomes include progression of underlying renal dysfunction, worsening of urine protein, and hypertension, whereas adverse fetal outcomes include fetal loss, intrauterine growth restriction, and preterm delivery. As such, pregnancy in young women with CKD is anxiety provoking for both the patient and the clinician providing care, and because the heterogeneous group of glomerular diseases often affects young women, this is an area of heightened concern...

REVIEW
Hua Su, Chun-Tao Lei, Chun Zhang
Interleukin-6 (IL-6) is a pleiotropic cytokine that not only regulates the immune and inflammatory response but also affects hematopoiesis, metabolism, and organ development. IL-6 can simultaneously elicit distinct or even contradictory physiopathological processes, which is likely discriminated by the cascades of signaling pathway, termed classic and trans-signaling. Besides playing several important physiological roles, dysregulated IL-6 has been demonstrated to underlie a number of autoimmune and inflammatory diseases, metabolic abnormalities, and malignancies...
