INTRODUCTION: This study aims to analyse the clinico-epidemiological characteristics of Asian patients diagnosed with livedo vasculopathy (LV). MATERIALS AND METHODS: We performed a retrospective analysis of all patients diagnosed with LV from 1997 to 2007 at our centre. RESULTS: Seventy patients were diagnosed with LV with a mean age of 39 years, female: male ratio of 3:1 and no racial predilection. Most cases remained purely cutaneous, presenting with painful leg ulcers and atrophie blanche. Peripheral neuropathy was the only extra-cutaneous complication (9%). In patients who were screened, associations included hepatitis B (7%) and hepatitis C (4%), positive anti-nuclear antibody (14%), positive anti-myeloperoxidase antibody (5%), positive anti-cardiolipin antibodies (7%) and positive lupus anticoagulant (2%). In 49 patients who achieved remission, 55% required combination therapy, most commonly with colchicine, pentoxifylline and prednisolone. In those treated successfully with monotherapy, colchicine was effective in 59% followed by prednisolone (17.5%), pentoxifylline (17.5%) and aspirin (6%). Mean follow-up period was 50 months. CONCLUSION: LV in Asian patients is a high morbidity, chronic relapsing ulcerative skin condition. Most patients require induction combination therapy for remission. As further evidence emerges to support a procoagulant pathogenesis, a standardised protocol is needed to investigate for prothrombotic disorders during diagnosis.
