Idiopathic Nephrotic Syndrome (INS) was defined as combination of a nephrotic syndrome and non-specific histological abnormalities of the kidney. Among these abnormalities, minimal change nephrotic syndrome (MCNS) is the most common. We report our experience with MCNS; its clinical course, treatments and outcomes. One-hundred twenty children (66 male, 54 female) with MCNS, admitted to Nephrology Department between 1987–2009 was assessed. Their clinical presentations, treatment and disease courses were reviewed. The mean duration of follow-up was 11.5 ± 1.9 years. Initially, all patients given prednisone 2 mg/kg/ day single dose per four weeks a followed by eight weeks of the same daily dose given every other day. After week 12, prednisone was progressively tapered off at the rate of 0.5 mg/kg per 15 daily intervals until complete discontinuation had been achieved by week 16. Steroid resistance was accepted as no achievement of remission following four weeks of prednisone 2 mg/kg/day followed by three intravenous pulses of corticosteroids. At the end of the initial steroid treatment, 106 (88.3%) patients were determinate steroid responsive while 14 (11.7%) patients were steroid resistance. Thirty-eight patients underwent biopsy. At the end of study recovery rate was increased from 88.3% to 94.1%. In conclusion, most of patients entered remission by our therapy end of follow up time. With the support of our satisfactory results among the whole study group, long-term prednisolone treatment still remains valid. [ABSTRACT FROM AUTHOR]
