Post-streptococcal acute glomerulonephritis: a clinical, bacteriological and serological study.

Eight hundred and sixty four children were admitted with Acute post-streptococcal glomerulonephritis (APSGN) at the Institute for Child Health, Madras, during the period January 1981 to January 1983. Majority of the cases followed infected scabies or impetigo. 135 children were investigated and followed up for a period of 1-2 years. The disease had an excellent prognosis in these children. None of those examined 2 years after discharge had proteinuria or hypertension. Group A beta hemolytic streptococcus (BHS) was isolated in 13.4% of patients and 11.25% of skin infection controls. Eight different T types were identified in patients and 6 T types in pyoderma cases. All patients and 87% of skin infection controls had elevated anti-D Nase B titres, while ASO titres were not significantly raised.
