Nephropaty IgA

Flávia Lara Barcelos, Tânia Maria de Souza Fontes
INTRODUCTION: The antineutrophil cytoplasmatic antibody (ANCA) is usually associated with pauci-immune crescentic glomerulonephritis (CrGN). However, the literature show an incidence unexpected high of ANCA in immunocomplex CrNP. The crescent IgA nephropaty is one of CrGN that associated with ANCAObjective:To relate an IgA nephropaty ANCA positive and sign of worse prognosis that improved with immunossupression. METHOD: 38-year-old pacient with arterial hypertension, renal impairment (CKD-EPI 37 ml/min/1,73 m2), non-nephrotic proteinuria and hematuria...

UNLABELLED: Glomerular protein handling mechanisms have received much attention in studies of nephrotic syndrome. Histopathological findings in renal biopsies from severely proteinuric patients support the likelihood of protein endocytosis by podocytes. ClC-5 is involved in the endocytosis of albumin in the proximal tubule. AIM: To investigate whether ClC-5 is expressed in the glomerular compartment and whether it has a role in proteinuric nephropathies. ClC-5 expression was studied using Real-time PCR in manually- and laser-microdissected biopsies from patients with type 2 diabetes (n 37) and IgA nephropathy (n 10); in biopsies of membranous glomerulopathy (MG) (n 14) immunohistochemistry for ClC-5 (with morphometric analysis) and for WT1 was done...

Immunoglobulin A nephropathy (N.IgA) is the world most common glomerular disease; 15-50% of patients develop loss of renal function in 10-20 years, and the rest remission or mild proteinuria/ hematuria. The optimal treatment is uncertain. Our aim was to develop evidence-based recommendations through research in Medline, Embasse, Lilacs and Cochrane Central Register of Controlled Trials. The study-quality was independently assessed by the reviewers following the Cochrane Renal Group checklist: randomization, blinding, intention-to-treat analysis and follow-up period...

UNLABELLED: HIV nephropathy (HIVAN) is the most frequent cause of chronic renal failure in HIV-infected black patients. However, the prevalence of other glomerulopathies mediated by immunocomplexes has increased in the last years. We report on the glomerular diseases observed in HIV patients in our Hospital. METHODS: A retrospective study of all patients with HIV infection and glomerular diseases diagnosed by renal biopsy. RESULTS: We found 27 patients with the following glomerular diseases: membranoproliferative glomerulonephritis (MPGN) in 8 patients, non-collapsing focal segmental glomerulosclerosis (FSGS) in 7, IgA nephropaty (IgA N) in 6, collapsing glomerulosclerosis in 4 (HIVAN, and membranous nephropaty (MN) in 2...

Few data are now avalable concerning renal pathology in black African. That is why we under took this study as a contribution to the better knowlege of pathological aspects of kidney disease in Dakar by analysing our 6 years's experience. It was a retrospective study concerning all the patients who underwent renal biopsyfrom January 1993 to December 1998. The samples were studied on light microscopy and immunoflorescence at the nephrology unit of Necker Hospital in Paris. We performed 115 renal biopsies during this period conceming 64 males and 51 females from 5 to 60 years old (mean age 28 years)...

IgA nephropathy is a primitive cronic idiopatic glomerulonephritis, characterized by diffuse depositis of IgA in the glomeruler mesangium. Familial cases are also descripted. IgA nephropaty is more frequent in males and in white rase. In Italy it's the most frequently recognized glomerulonephritis in renal biopsia (20%), especially in patients with dismorfic micro or macroematuria and nephrotic proteinuria. Clinical presentation is often in association with respiratory tract or gastrointestinal disorders. The most relevant pathogenetic hypothesis suggest an IgA abnormal glycosilation, with mesangial IgA aggregation, increased mesangial reactivity and release of inflammatory mediators and fibrotic agents...

This series of articles on the management of glomerulonephritis (GN) has been prepared by a team of experts in the evidence-based format consistent with peer review of published data. Each author was asked to review the literature for his assigned histological type, with emphasis on therapy and limited to adult studies. The age limit was not considered for minimal change disease and focal segmental glomerulosclerosis, because of the high prevalence of these glomerulopathies in children. The particular treatment recommendations for each type of glomerular disease were graded by each author according to the amount of evidence provided in these reviewed studies...
