cyclosporin treatment at 7.5 mg/kg/day for 6 weeks and then 4 mg/kg/day for on year and methotrexate 5 mg/kg/day for one year.
Drug: cyclosporin and methotrexate
cyclosporin 7.5 mg/kg/day for 6 weeks and then 4 mg/kg/day for one year and methotrexate 5 mg/kg/day for one year. After 6 weeks, cyclosporin doses will adjusted to maintain blood cyclo levels to 100-200 ng/ml.
Objective: Although high doses of cyclosporin (cyclo) inhibits the development of type 1 diabetes mellitus, its usefulness is limited by its toxicity. Since methotrexate (mtx) and cyclo synergistically inhibit other disease processes, we hypothesized that low dose cyclo and mtx therapy could safely induce remission.
Research Design and Methods: In an open pilot study, insulin dose and glycemic control will be compared in children with new onset Type 1 diabetes administered cyclo at 7.5 mg/kg/day for 6 weeks and then 4 mg/kg/day and mtx 5 mg/kg/day for one year with control children. After 6 weeks, doses were adjusted to maintain blood cyclo levels to 100-200 ng/ml.
