Idiopathic Nephrotic Syndrome

Brief summary

This study will compare a short-term course (12 week) glucocorticoid regimen with the Conventional 24-week regimen as originally proposed by KDIGO. The purpose of the study is to determine a short-term course (12 week) of glucocorticoid decreases the time to first relapse in adults presenting with steroid sensitive nephrotic syndrome.

Interventions

DRUGConventional 24-week glucocorticoid regimen

Weeks 1 - 4, Prednisolone 1mg/kg/day (max 80mg); Weeks 5 - 6: Prednisolone 0.8mg/kg/day (max 60mg); Weeks 7 - 8: Prednisolone 0.6mg/kg/day (max 50mg); Weeks 9 - 10: Prednisolone 0.5mg/kg/day (max 40mg); Weeks 11 - 12: Prednisolone 0.4mg/kg/day (max 30mg); Weeks 13 - 16: Prednisolone 0.3mg/kg/day (max 25mg); Weeks 17 - 20: Prednisolone 0.2mg/kg/day (max 15 Weeks 21 - 24: Prednisolone 0.1mg/kg/day (max 10mg).

DRUGshort-term course (12 week) glucocorticoid regimen

Weeks 1 - 4, Prednisolone 1mg/kg/day (max 80mg); Weeks 5-8: Prednisolone 1mg/kg/day (max 80mg) on alternate days; 9-12: Prednisolone 0.5mg/kg/day (max 40mg) on alternate days
