To determine the efficacy of tacrolimus in the management of NS(nephrotic syndrome) , the investigators designed this prospective study. The investigators will enroll 100 children with NS(frequent relapse steroid dependent NS, steroid resistance NS) who will be treated with tacrolimus (0.1-0.2 mg/kg/day in two divided doses over 12 h adjusted to a trough level between 5 and 10 ng/ml) for 12 months in combination with low-dose steroids. Other therapies will be included angiotensin-converting enzyme inhibitors, antihypertensive drugs, multivitamins and lipid-lowering agents.

Follow-up is every second week for the first 4 weeks, then monthly. After initiation of tacrolimus therapy, blood was drawn each visit to determine tacrolimus trough levels.

Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tacrolimus
Drug: Tacrolimus
