BACKGROUND: The prognostic factors, the outcome and the most favorable treatment regimen are not entirely known for children with membranoproliferative glomerulonephritis (MPGN). MPGN is a rarely observed disease more prevalent in adolescents, so we aimed to review the clinical and histological properties, treatments and the outcome of our patients who were diagnosed as MPGN.
METHODS: Fifty-one children - diagnosed with MPGN - were selected from biopsy records in Dr. Sami Ulus Maternity and Children's Hospital Pediatric Nephrology Department from January 1999 to January 2011. A retrospective analysis was made of 33 regularly followed children.
RESULTS: Thirty-three patients were identified, 13 female and 20 male. Their age groups at presentation ranged from 4 to 15 years. The following duration was 26-144 months (mean 74). Following the initial treatment, 20 (60%) patients achieved complete remission. Six patients with nephrotic syndrome and one with non-nephrotic proteinuria showed partial remission. The condition of one patient with nephrotic syndrome was unchanged with the persisting symptoms. The one patient with nephrotic syndrome and four others with non-nephrotic proteinuria did not respond to initial treatment as their renal functions decreased gradually.
CONCLUSION: We concluded that only degree of tubulointerstitial damage on the initial biopsy is determinative for prognosis of childhood MPGN. If the patient receives high doses of steroid therapy in the early stages, their treatment is more likely to be successful. The effect of immunosuppressive treatment on MPGN is not clear.
