53 in Case Group (given montelukast 5mg at bed time). All patients were induced with prednisolone 2mg/kg single morning dose with breakfast for total 4 weeks. Patients who did not achieve remission after 4 weeks' full dose were labeled steroid resistant nephrotic syndrome (SRNS). Children with steroid sensitive nephrotic syndrome SSNS were further treated by prednisolone 1.5 mg/kg single morning dose with breakfast every other day for the next 4 weeks. Prednisolone was then tapered by reducing 25% dose fortnightly and completely stopped in 8 weeks. Patients in the Case Group continued taking montelukast after stopping steroids. All patients were followed up every 4-8 weeks for a minimum of 12 months to look for response to treatment, side effects of medications, other co-morbidities, and the number of relapses. Relapses were treated with repeat prednisolone doses according to the protocol of treatment for relapse.

We wanted to know the role of leukotriene receptor antagonist (LTRA) montelukast in preventing relapses in idiopathic childhood nephrotic syndrome (NS)

Relapse was labeled as recurrence of proteinuria 3+ or more for 3 consecutive days with or without edema
