About

Primitive kidney disease IgA, represented by Berger's disease and rheumatoid purpura nephropathy, are the first cause of kidney failure from chronic glomerulonephritis: changes in 20 years to end-stage renal failure is described in 10 to 30 % of cases in Berger's disease and in 15 to 20% of cases in nephropathy HSP. These two pathological entities share biological and histological characteristics, as well as common pathophysiological mechanisms, particularly the production of abnormally glycosylated IgA1 promoting their proliferation in the mesangium. Tonsils part of Iga abnormal production sites that would be associated with an infectious stimulus, tonsillectomy has been studied as a possible treatment in primitive IgA nephropathy. The benefit of tonsillectomy is controversial: many Japanese studies demonstrate its effectiveness in terms of reduction of proteinuria, improved renal function in the long term regression of histological lesions and reduced risk of relapse following clinical remission whereas European studies do not suggest its effectiveness in treating IgA nephropathy. In this context, the aim of our study is to describe the scope of practice of tonsillectomy in the treatment of primary renal disease in IgA child in the inter East region and describe the short renal become Strasbourg end of the cohort that received this treatment.
