[Familial incidence of post-streptococcal glomerulonephritis].

The investigation on siblings of AGN patients has shown a streptococcus carrier evidence of 45%, while glomerulonephritis incidence was 15%. These data allowed us to classify our population as highly susceptible to bacterial dissemination and to the development of non-suppurative complications. Renal compromise was clinical and histologically classified. Subclinical forms showed glomerular lesions of mesangial localization, while clinical forms exhibited variable degrees of cellular proliferation. All patients recovered except one who died of a rapidly progressive form.
