Treatment of the cutaneous lesions of systemic lupus erythematosus with thalidomide.

Twenty three patients with SLE and cutaneous lesions not responsive to chloroquine, photoprotectors and corticosteroid in doses < 0.5 mg/kg/day were treated with thalidomide 300 mg/day. Three patients presented side effects and had to discontinue treatment. Eighteen of the remaining 20 patients (90%) had complete remission of the cutaneous lesions and 2 had partial improvement. Another important parameter of improvement was a reduction in the average prednisone dose required from 40.5 mg/day to 17.4 mg/day. The most frequent side effects were drowsiness in 52% of cases and abdominal distention in 22%. These symptoms were reversed by dose reductions in all but one patient. Thalidomide was shown to be efficient in the treatment of cutaneous lesions unresponsive to more usual treatments.
