Factor XIII deficiency in Pakistan

ABSTRACT

Patients with undiagnosed haemostatic defects seen at the Aga Khan Hospital and Fatimid Blood Transfusion Centre during the period of 7 years [1985-1992] were screened with routine tests including bleeding time [BT], whole blood clotting time [CT], platelet count, activated partial thromboplastin time [APTT], prothrombin time [PT] and 5 molar urea test. Nine patients had a positive 5 molar urea test indicating factor XIII deficiency. Rest of the screening tests were normal in these patients. High incidence of consanguinity was observed in affected families. Clinical features included excessive bleeding from umbilical stump, bruising, post-traumatic bleeding, epistaxis, melaena and intracerebral bleeding. All the patients were treated with fresh frozen plasma and cryoprecipitate
