Background
Primary nephrotic syndrome (PNS) in children is a common problem worldwide. The pathological pattern of PNS differs between countries. However, data on the pathological pattern of PNS in Egyptian children are scant. This study was conducted to determine indications and results of renal biopsy in Egyptian children with PNS from a single tertiary children’s hospital.
Methods
Medical records of all children with PNS aged 3 months–18 years who underwent renal biopsy from 1998 to 2012 at Mansoura University Children’s Hospital were retrospectively reviewed.
Results
A total of 741 patients (441 males, 300 females) underwent 798 biopsies of which only four specimens were insufficient. Mean age at time of biopsy was 7.4 ± 3.6 years. The main indication for biopsy was steroid resistance (n = 354, 44.4 %) followed by atypical PNS (n = 234, 29.3 %) of which gross hematuria was the most common cause. Minimal change disease (MCD) and its variants were the most frequent pathology (n = 431, 54.3 %) irrespective of biopsy indication, and incidence of focal segmental glomerulosclerosis was observed to be increasing over the years.
Conclusion
This is the first large study on the pathological pattern of PNS in children from Egypt, and it shows that MCD is the most frequent underlying pathology and steroid resistance is the most frequent indication for biopsy.
