dc.description.abstractBecause of the very short half-life of factor VII, prophylaxis in factor VII deficiency is considered a difficult endeavor. The clinical efficacy and safety of prophylactic regimens, and indications for their use, were evaluated in factor VII-deficient patients in the Seven Treatment Evaluation Registry. Prophylaxis data (38 courses) were analyzed from 34 patients with severe factor VII deficiency (<1-45 years of age, 21 female). Severest phenotypes (central nervous system, gastrointestinal, joint bleeding episodes) were highly prevalent. Twenty-one patients received recombinant activated factor VII (24 courses), four received plasma-derived factor VII, and ten received fresh-frozen plasma. Prophylactic schedules clustered into frequent courses (three times weekly, n=23) and infrequent courses (<= 2 times weekly, n=15). Excluding courses for menorrhagia, frequent and infrequent courses produced 18/23 (78%) and 5/12 (41%) excellent outcomes, respectively; relative risk, 1.88; 95% confidence interval, 0.93-3.79; P=0.079. Long-term prophylaxis lasted from 1 to >10 years. No thrombosis or new inhibitors occurred. In conclusion, a subset of patients with factor VII deficiency needed prophylaxis because of severe bleeding. Recombinant activated factor VII schedules based on frequent administrations (three times weekly) and a 90 mu g/kg total weekly dose were effective. These data provide a rationale for long-term, safe prophylaxis in factor VII deficiency.en_US
