Abstract
Background: Livedoid vasculitis is characterized clinically by smooth or depressed ivory-white scars surrounded by hyperpigmentation and telangiectasia with or without preceding purpuric infiltrated papules and plaques and histologically by intravascular deposition of fibrin. Its etiology remains obscure and therapy very difficult. Objective: Our purpose was to test the efficacy of low-dose danazol in the treatment of livedoid vasculitis. Methods: Seven patients with active lesions of livedoid vasculitis were treated with low-dose danazol (200 mg, orally, daily). Laboratory coagulation and fibrinolysis parameters, including antithrombin III, protein C, protein S, tissue plasminogen activator, plasminogen, α2-antiplasmin and fibrinogen, were evaluated before and during the therapy. Results: Six of the 7 patients completed the treatment. After the therapy, all 6 patients had rapid cessation of new lesion formation, prompt reduction in their pain and healing of ulcers. A significant elevation of plasminogen and a decrease in fibrinogen levels were noted 1 month after initiation of the therapy (p = 0.028). The level of fibrinogen seemed to parallel the disease activity in individual patients. In addition, in most of these patients, the levels of antithrombin III, protein C, protein S and α2-antiplasmin tended to increase after the treatment. However, the differences were not statistically significant. Abnormalities of tissue plasminogen activator levels were less consistent. Low-dose danazol was well tolerated without major side effects. Conclusion: We concluded that low-dose danazol was effective in the treatment of livedoid vasculitis, without unacceptable side effects. ? 1997 S. Karger AG, Basel.
