[Glomerulonephritis with transient C3 hypoclompimentemia and endotheliomesangial glomerulonephritis in childhood. A long-term experience].
62 children (20 girls and 42 boys, ranging in age between 3 and 15 years), presenting with acute hypocomplementemic glomerulonephritis or morphologically confirmed endotheliomesangial glomerulonephritis, were admitted to the University Children's Hospital, Berne from 1970 to 1991. The annual incidence of cases of acute hypocomplementemic glomerulonephritis was stable during the study period. The site of the antecedent infection was the throat in 26 patients, upper respiratory tract in 15, the skin in 9, and unknown in 10. The latent period ranged from 0.5 to 3.5 weeks. 41 patients developed hypertension and 17 renal failure. Hypertensive complications were observed in 6 patients and remitted completely in 5 cases. A nephrotic syndrome (edema, proteinuria of 40 mg/[m2.h], albuminemia < 25 g/l) was observed in 11 patients. Microscopic hematuria persisted in many patients for one year or more. Proteinuria remitted in all but one patient, who was found to have Alport syndrome. This study shows the stable frequency of hypocomplementemic glomerulonephritis since 1970, its good prognosis, and the importance of the measurement of C3-complementemia in children presenting with acute glomerulonephritis.
