DCP therapy comprises an intravenous infusion of 100 mg dexamethasone in 500 ml of 5% glucose over 1–1½ hours on 3 consecutive days along with cyclophosphamide 500 mg in the same drip on the first day. This was repeated at 4-week intervals till 9 months after all the lesions cleared. In between the DCP therapy she was given 50 mg cyclophosphamide orally daily. Results: The skin lesions cleared with 11 DCP therapies. There was no relapse 24 months after stopping all treatment. Conclusion: DCP therapy appears to put SLE into prolonged remission.
