Retrospective analysis of 1312 patients with haemophilia and related disorders in a single Chinese institute.

Abstract

With 1.3 billion people, China has the largest population in the world, and therefore has the largest population of persons with haemophilia (PWH). As there is no national registry for haemophilia, it is difficult to ascertain how many PWH have actually been diagnosed. Between January 1983 and June 2002, 1312 patients with coagulation disorders were referred to our hospital, and 1190 patients were evaluable. Among them, 1069 (89.8%) patients had haemophilia, 68 had vWD, 20 had factor XI deficiency, 10 had acquired factor VIII inhibitor and 23 had other coagulation disorders. Of the 1069 PWH, 14.7% were unclassified, 38.4% severe, 35.7% moderate and 11.1% mild. If the unclassified cases were excluded, 45.1% were severe, 41.9% moderate and 13.0% mild. Twenty-nine of the 68 vWD patients had vWF:Ag <5%, and subcategorized as type 3 vWD. Because vWF multimer analysis was not performed in our centre, the remaining vWD patients were not subdivided.
