BACKGROUND: Health care officials and legislators need accurate data on prevalence and numbers of individuals with bleeding disorders in order to plan and allot their budgets; the manufacturers of coagulation factors also need these data to estimate the amount of factors required to prevent scarcity of these products. MATERIALS AND METHODS: We surveyed the prevalence of haemophilia A, haemophilia B, von Willebrand's disease and rare bleeding disorders in North-Eastern Iran. The survey was done in the period from September 2009 to March 2011. Information was collected from the medical records in three major hospitals and a haemophilia centre; the patients' updated data were obtained by telephone. RESULTS: Overall in the current survey 552 patients with inherited coagulation disorders were identified and their medical records obtained. Of these, 429 (77.5%) had common bleeding disorders (haemophilia A, haemophilia B, von Willebrand's disease), 85 (15.6%) had rare bleeding disorders (deficiency of coagulation factors V, VII, X, XIII, I, XI, combined factor V and VIII deficiency) and 38 (6.9%) had platelet disorders.The commonest bleeding disorders were haemophilia A (n=287, 51.9%), haemophilia B (n=92, 16.6%), von Willebrand's disease (n=50, 9%), factor V deficiency (n=21, 3.8%), factor VII deficiency (n=19, 3.4%), factor X deficiency (n=2, 0.36%), combined factor V and VIII deficiency (n=28, 5.8%), factor XIII deficiency (n=11, 1.99%), factor XI deficiency (n=2, 0.4%), afibrinogenaemia (n=2, 0.36%) and platelet disorders (n=38, 6.9%). DISCUSSION: There is notable population of individuals with bleeding disorders in North-Eastern Iran.
