Materials and Methods:

This was a descriptive and observational study. Patients under 16 years of age diagnosed with post-infectious glomerulonephritis were included. We excluded patients with unknown C3, previous renal disease or secondary nephritic syndrome. Variables: sociodemographic factors, season of the year, type of previous infection, creatinine clearance, dialysis requirement.. Data were analyzed using the SPSS program.


We enrolled 160 patients, 68.1% of them were male with an M / F ratio of 2.2 to 1. The most affected age group was 6 to 12 years (65%). 60% of the patients came from the rural area, with parents who only a primary-level education and lived in overcrowded conditions. The most frequent clinical form was acute nephritic syndrome (97.5%) and the most prevalent preceding infection was pyoderma (52%). Alteration of renal function was observed in 51.25%, pulmonary edema in 40% and hypertensive encephalopathy in 17%. No patient died.
