Sixty two children were included in a collaborative study to determine the prognosis for lupus nephritis. Renal involvement was confirmed by histologic study of renal biopsy specimens which were classified into five categories: minimal lesions (11 cases, 18%); focal segmental glomerulonephritis (15, 24%); diffuse proliferative glomerulonephritis (30, 48%); membranous nephropathy (5, 8%); and gl...

Grave’s disease is a common form of autoimmune thyroiditis which has been successfully treated with anti-thyroid drugs for more than half a century. However, these drugs may cause major complications including agranulocytosis, hepatotoxicity and immunological disturbances such as lupus erythematosus syndrome. Anti myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) mediated crescenti...

A 67-year-old man was evaluated for haematuria, with a rising creatinine level from 88 to 906 µmol/L and positive c-anti-neutrophil cytoplasm antibody (ANCA)/anti-proteinase 3 (anti-PR3). A kidney biopsy revealed necrotizing glomerulonephritis with a 'full-house' pattern on immunofluorescence microscopy. Echocardiography and blood cultures growing Gemella sanguinis diagnosed endocarditis. Dialy...

The contribution of individual molecular aberrations to the pathogenesis of systemic lupus erythematosus (SLE), an autoimmune disease that affects multiple organs, is often difficult to evaluate because of the presence of abundant confounding factors. To assess the effect of increased expression of the phosphatase protein phosphatase 2A (PP2A) in T cells, as recorded in SLE patients, we generat...

objectives this report describes the indication, histopathological patterns, and epidemiology of renal diseases in children in india. patients and methods this is a single-center study on renal biopsies performed between january 2008 and december 2013 in 346 children (age ≤ 14 years). results eleven (3.17%) biopsies were inadequate, and 335 biopsies were considered for analysis. the mean age wa...

Renal involvement in systemic lupus erythematosus (SLE) is usually immune complex mediated and may have multiple different presentations. Pauci-immune necrotizing and crescentic glomerulonephritis (NCGN) refers to extensive glomerular inflammation with few or no immune deposits that may result in rapid decline in renal function. We report a case of a 79-year-old Hispanic male with a history of ...

MicroRNAs contribute to the pathogenesis of certain diseases and may serve as biomarkers. We analyzed glomerular microRNA expression in B6.MRLc1, which serve as a mouse model of autoimmune glomerulonephritis. We found that miR-26a was the most abundantly expressed microRNA in the glomerulus of normal C57BL/6 and that its glomerular expression in B6.MRLc1 was significantly lower than that in C57...

T cell-specific adaptor protein (TSAd) is a T lineage-restricted signaling adaptor molecule that is thought to participate in the assembly of intracellular signaling complexes in T cells. Previous studies of TSAd-deficient mice have revealed a role for TSAd in the induction of T cell interleukin 2 secretion and proliferation. We now show that TSAd-deficient mice are susceptible to lupus-like au...

The New Zealand Black (NZB) Lbw2 locus (lupus NZB x New Zealand White (NZW) 2 locus) was previously linked to mortality and glomerulonephritis, but not to IgG autoantibodies, suggesting that it played a role in a later disease stage. To define its contribution, (NZB x NZW)F1 hybrids (BWF1) containing two, one, or no copies of this locus were generated. Lack of the NZB Lbw2 indeed reduced mortal...

BACKGROUND Although Indigenous Australians, New Zealand Maori and Pacific Island people comprise an unduly high proportion of patients treated for end-stage renal disease (ESRD) in the two countries, no population-based age- and disease-specific rates have been published. METHODS From data provided to the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA), truncated age- and...
