2. Adjunct therapy of nephrotic syndrome: Each patient will remain on his or her baseline therapy immunosuppressive therapy with cyclosporine, tacrolimus or mycophenolate mofetil. Steroids dose will be tapered to 0.5mg/kg, to a maximum of 40 mg, every other day at the time of starting galactose. If patient achieves remission, as indicated by negative first morning urine for protein for 3 consecutive days, alternate day steroid therapy will be tapered by 0.12mg/kg/dose or by 10 mg/dose, once per week. If patient has sustained remission for 1 month, and is off prednisone, the dose of immunosuppressive drugs will be lowered by 25% per month until off. BP will be controlled to below 95th percentile for height. If patient is on ACE inhibitors or ARBs, the dose will stay unchanged during the duration of galactose administration unless patient is experiencing side effects of therapy. If additional therapies for control of hypertension are needed, they would be chosen from the antihypertensive drugs other than ACE inhibitors and ARBs. Diuretics will be prescribed as needed for the symptomatic relief of edema. Adjunct therapy medications described in this section are standard of care and are not for research purposes.
