The use of tacrolimus in NS(nephrotic syndrome) has been reported in single and small series case reports. To determine the efficacy of tacrolimus in the management of NS, 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. Subsequently , monthly measurements were made until stable levels of tacrolimus were achieved. Urine was analyzed for proteinuria at each visit. Serum creatinine, glucose, albumin and alanine aminotransferase were measured and complete blood counts were obtained at each visit during the study.
