Bleeding symptoms in 27 Iranian patients with the combined deficiency of factor V and factor VIII

Inherited deficiency of factors V and VIII is the most frequent combined coagulation defect, The cases reported so far are mostly single cases or small series from different centres, making it difficult to evaluate the overall pattern of clinical manifestations of the combined defect. We examined at a single institution 27 Iranian patients. Mucocutaneous and post-surgical bleeding were the most frequent clinical manifestations. The presence of two defects did not make the severity of breeding greater than that expected in patients with single coagulation defects of similar degrees.
