BackgroundAcute cutaneous sarcoidosis is generally spontaneously regressive but persistent chronic cutaneous lesions are esthetically prejudicial. There have been several case reports on thalidomide efficacy but long-term outcome is unknown. We report results in 10 cases of cutaneous sarcoidosis treated with thalidomide.Patients And MethodsData from ten patients with sarcoidosis treated with thalidomide between January 1998 and March 1999 were collected from delivery authorizations and analyzed. All ten patients had chronic cutaneous sarcoidosis resistant to conventional therapy. Six patients had an associated visceral localization and disease duration of 2 to 18 years (median 6 years). We considered that regression was complete when erythema and infiltration had totally disappeared, that regression was incomplete when cutaneous signs remained, and that treatment had failed when no effect was observed or when the disease worsened.ResultsDisease regression was noted in 7 patients for a daily dose of 1.84 mg/kg for 2.8 months. Skin lesions totally regressed in 3 patients, an incompletely in 4. Treatment failed in 3 patients. Patients were treated for 10 months (2 to 21 months). The daily dose of thalidomide was gradually reduced in 5 of 7 patients for whom treatment was effective. Three of these 5 patients relapsed and thalidomide was again given and was effective again at the same dose and after the same delay. We observed improved kidney function in one patient, improvement in nasal infiltration in one other and complete regression in 3 patients who achieved long lasting reduction in angiotensin convertase level. When treatment failed, the daily dose was 1.15 mg/kg and the treatment had to be stopped for 2 patients. Side effects were minor, excepting 2 cases of neuropathy.DiscussionThis open study of 10 patients treated with thalidomide showed the efficacy of a 1.84 mg/kg daily dose in 7 out of 10, but complete regression of the lesions was obtained in only 3 patients. Thalidomiide appears to suspend the disease, with relapse when the drug is discontinued and efficacy at re-introduction. This would argue against a placebo effect. The mode of action could involve immunomodulating and antiinflammatory mechanisms.
