          Abstract

          Common side effects of dabigatran are bleeding, bruising, nausea, diarrhea, and abdomen discomfort. Skin reactions were not often noted (<0.1%). We report a case of 70-year-old male who developed dabigatran related skin reaction resistant to usual therapy. Skin biopsy revealed leukocytoclastic vasculitis.

          Systemic vasculitis in adults in northwestern Spain, 1988-1997. Clinical and epidemiologic aspects.

          The vasculitides constitute a heterogeneous group of diseases characterized by blood vessel inflammation and necrosis with different but frequently overlapping clinical and pathologic manifestations. The incidence of these conditions is frequently controversial. To further investigate the incidence and clinical manifestations of vasculitides, we reviewed the spectrum of these diseases in an unselected population of adults (age > 20 years) from northwestern Spain during a 10-year period. From January 1988 through December 1997, 267 adults were diagnosed as having vasculitis. The overall average annual incidence rate of vasculitis in the region of Lugo, Spain, between 1988 and 1997 for the population older than 20 years was 141.54/million. Primary vasculitis (115.04/million for the population older than 20 years; 81.3%), especially giant cell arteritis (GCA) was the most common group. Small vessel primary vasculitis (hypersensitivity vasculitis and Henoch-Schönlein purpura) was the second most common group. Both GCA and small vessel primary vasculitis had a good outcome. However, although less common, patients with medium and small vessel primary vasculitis, in particular those with polyarteritis nodosa, had a high mortality related to the systemic manifestations of the disease or to the immunosuppressive therapy. Among the group of adults with secondary vasculitis (26.51/million; 18.7%), rheumatic diseases and specifically those occurring in the context of rheumatoid arthritis were the most common group. Patients with secondary vasculitis had clinical or laboratory data that may suggest the presence of an underlying disease. In summary, systemic vasculitides are somewhat more common than previously considered. As in other western countries, GCA constitutes the most common type of vasculitis in northwestern Spain. Better physician awareness may contribute to the progressive increase in the recognition of these conditions.

            Colchicine in the treatment of cutaneous leukocytoclastic vasculitis. Results of a prospective, randomized controlled trial.

            Cutaneous leukocytoclastic vasculitis is an inflammatory vascular disease with a variable course. There is no defined therapy for this entity. Contradictory data on the effect of colchicine have been reported. To determine the efficacy of colchicine in cutaneous leukocytoclastic vasculitis, 41 patients were randomly selected to receive oral colchicine, 0.5 mg twice daily, or topical emollients. Response to treatment was judged according to the reduction in the number of lesions. After 1 month, in those patients in whom a complete or no response was achieved, therapy was withdrawn; in those with a partial response, treatment was maintained for the following 2 months. At the end of 3 months, treatment was continued only in those patients in whom a relapse occurred. Twenty patients in each group completed 1 month of treatment. One patient taking colchicine dropped out because of diarrhea. At the end of the first month of the study, five patients in the control group and four in the colchicine group achieved a complete response. Nine patients who had a partial response (four in the colchicine group and five in the control group) continued to receive treatment for the following 2 months. Three patients in the colchicine group suffered a relapse after discontinuing therapy but experienced remission with reinstitution of therapy. At the end of the 3 month period, 12 patients in the colchicine group and 10 patients in the control group showed no significant response. Complete response was achieved in five patients in the colchicine group and in seven in the control group. At the 1-year follow-up, 10 patients in each group had no clinical evidence of cutaneous vasculitis. Colchicine had no significant therapeutic effect in this controlled study. However, the finding that relapse occurred on cessation of colchicine therapy in three complete responders suggests that colchicine can be effective in some patients, despite our negative results.
