Long versus standard initial prednisolone therapy in children with idiopathic nephrotic syndrome

Area of Science:

• Pediatric Nephrology
• Clinical Pharmacology

Background:

• Idiopathic nephrotic syndrome (INS) is a common kidney disorder in children.
• Steroid therapy, particularly prednisolone, is the mainstay treatment for INS.
• Optimal duration of initial prednisolone courses for steroid-sensitive INS remains debated.

Purpose of the Study:

• To compare the efficacy of a prolonged initial prednisolone regimen versus a standard regimen in preventing relapses of INS in children.
• To assess the impact of extended initial prednisolone therapy on relapse rates and adverse effects over a one-year follow-up period.

Main Methods:

• A randomized controlled trial involving children with newly diagnosed, steroid-sensitive INS.
• Patients received either a long regimen (6 weeks daily, 6 weeks alternate-day prednisolone) or a standard regimen (4 weeks daily, 4 weeks alternate-day prednisolone).
• Primary outcome was relapse within one year; adverse effects were also monitored.

Main Results:

• Relapse rates within one year were 73.2% in the long regimen group and 64.5% in the standard group (Odds Ratio: 0.80; 95% CI: 0.22, 2.05; p=0.696).
• No statistically significant difference in relapse rates or adverse effects was observed between the two groups.
• A total of 72 children completed the study (41 long group, 31 standard group).

Conclusions:

• Prolonging the initial prednisolone course for steroid-sensitive INS does not appear to offer a significant benefit in reducing relapse rates within the subsequent year.
• The findings suggest that standard prednisolone regimens are sufficient for the initial treatment of steroid-sensitive INS.
• Further research may explore other factors influencing relapse in INS.
