Background. In 1997, the Clinic for Nephrotic Syndrome was established at the Hospital de Pediatría, Centro Médico Nacional Siglo XXI, Instituto Mexicano del Seguro Social (Mexico City); 30-50% of children with steroid-resistant nephrotic syndrome develop chronic renal failure and 60-80% achieve remission with cyclosporine. The objective of the study was to report treatment response and prognosis using the described scheme in a group of patients with steroid-resistant nephrotic syndrome. Methods. Retrospective study in children with steroid-resistant nephrotic syndrome was done. Remission frequency and renal survival were measured. Results. One-hundred fifty seven patients were studied; 66.7% were male. Mean age at diagnosis was 5.9 ± 4.2 years. Biopsies showed 33 results (21.9%) with minimal changes (MC), 74 (49%) with diffuse mesangial proliferation (DMP) and 44 (29.1%) with focal segmental glomerulosclerosis (FSGS). Mean follow-up time was 59.3 months (minimum 3 months, maximum 178 months); 59% were on cyclosporine and 17.3% cyclophosphamide. Twenty six patients received both treatments and six patients received all three medications; 78.2% entered remission, 5.8% were on dialysis and 1.9% died. Five-year renal survival was 92.9% and 10-year survival was 80%. Remission in patients with MC and DMP was 79.8% and 86.5%, respectively and in FSGS was 59.1%. Chronic renal failure was found more often in FSGS (20.4%). Risk of developing renal failure with FSGS compared with DMP was 4.7 times and FSGS compared with MC risk was 8.7 times greater. Conclusions. Similar rates of remission and better renal survival were found compared with the literature.
