[The most frequent forms of acute glomerulonephritis in children. Epidemiology and prognosis].

Acute poststreptococcal-(PSGN), idiopathic mesangial Ig-A-(IgAGN) and Henoch-Schönlein-glomerulonephritis (HSGN) have been selected for this review article as most frequent types of GN in children. Consequent to inapparent forms, the incidence of all three types is unknown. Age and sex distribution seem to be similar in IgAGN and HSGN. Active inflammatory parenchymal lesions are self limited in PSGN. However, in some children with HSGN and in very few with IgAGN progression to renal failure occurs. The longer the observation times, the better are the results of studies on prognosis in children with PSGN, whereas the frequency of renal failure in IgA- and particularly in HSGN increases with time.
