Abstract
In this study, the clinical, laboratory and histopathological features of 50 children with membranoproliferative glomerulonephritis are reviewed. Age distribution varied from 5 to 15 years. The clinical presentation in the patients was nephrotic syndrome (24%), acute nephritic syndrome (20%) and nephritic/nephrotic syndrome (56%). Hypertension, macroscopic hematuria and hypocomplementemia were present in 40 percent, 58 percent and 34 percent of the patients, respectively. Light microscopic findings were as follows: glomerular lobulation (36%), mesangial sclerosis (20%), tubulointerstitial findings (36%), and crescents (26%). C3 (93%) was the most common immunofluorescence and IgM (86%), the most frequently encountered immunoglobulin. Response to treatment could not be anticipated by the initial clinical and laboratory features. Patients who did not have tubulointerstitial changes tended to have a greater response to therapy.
