We report on 21 children with poststreptococcal glomerulonephritis (PSGN). The diagnosis was based on clinical and laboratory criteria. 19/21 had a clinically apparent throat infection initially, but only 6 received antibiotic treatment. Initial symptoms were: macrohematuria (20/21), edema (10/21), arterial hypertension (6/21), reduced creatinine-clearance (11/21), and proteinuria (18/21). No Patient was dialyzed. After an interval of 0.3 to 25 months 19 children are asymptomatic. All patients have normal creatinine-clearances; none is hypertensive. The present data show that PSGN has not disappeared in Mid-Europe. Remarkable acute disturbances occurred, which healed in almost all cases. The importance of accurate bacteriologic diagnosis and adequate therapy is emphasized.
