Methylprednisolone Pulse Therapy in Adult-Onset Minimal Change Nephrotic Syndrome / 대한신장학회지

ABSTRACT

PURPOSE: The incidence of complete remission is lower and the relapse is more frequent in adult-onset minimal change nephrotic syndrome (MCNS) are observed especially when compared with those in children. This study was designed to examine the effect of methylprednisolone pulse therapy in adultonset MCNS comparing to oral steroid as an initial therapeutic modality. METHODS: We have retrospectively reviewed the clinical data of 25 adult-onset MCNS patients. Twelve patients were treated with three intravenous pulses of methylprednisolone (1 g daily) followed by oral prednisolone 1 mg/kg daily for 4-8 weeks and also by low doses of oral prednisolone for 4-6 months (MP group) Thirteen patients were initially treated with oral prednisolone 1 mg/kg daily for 4-8 weeks and then with low doses of oral prednisolone (PD group). RESULTS: The response to therapy was similar between MP and PD group, with a complete remission obtained in 83.3% and 84.6%, respectively. No statistically significant difference between the two groups was observed in the rate of response at 8 weeks (58.3% versus 69.2%). The mean time to response was not different between MP group (37.9+/-28.0 days) and PD group (45.5+/-40.2 days). No difference was recognized between the two groups with respect to relapse rate. CONCLUSION: These data suggest that a short course of methylprednisolone pulse therapy followed by oral prednisolone is not superior to oral prednisolone therapy as an initial therapeutic modality in adult-onset MCNS.
