The outcome of acute poststreptococcal glomerulonephritis (APSGN) is still controversial. Whereas many studies show a good prognosis, particularly in children, late morphologic and functional renal abnormalities have been described. To verify this latter finding, we evaluated the sodium handling of the kidney several years after APSGN. Eleven subjects (9 children and adolescents and 2 adults) were studied 2 to 3 years after APSGN. At the time of the study all patients were well, without pathologic urinary findings and with normal blood pressures. Five healthy subjects (3 adults and 2 children) served as controls. Following two control periods of 30 min, an i.v. saline load (2.5% NaCl, 1 l/1.73 m2 body surface area) was administered over 45 min. Sodium excretion was measured during the control and salt-loading periods, and during four additional 30-min collection periods. No exaggerated natriuresis was found. We therefore conclude that epidemic APSGN in Israel carries not only an excellent clinical but also a good renal functional prognosis.
