The primary nephrotic syndrome in children at Ramathibodi Hospital: clinical and clinicopathological study

Mesangial proliferative glomerulonephritis (MesPGN) is the most common histopathological finding of primary nephrotic syndrome in Thai children. Prediction of glomerular morphology is possible by the clinical characteristics: the age at onset older than 6 years old, occurring mostly in males, with or without hematuria, no hypertension, normal serum creatinine level, response to initial corticosteroid therapy but frequent relapses. Epidemiological study pertaining to associated environmental factors and immunological response of Thai children is needed.
