RESUMO
Clinical and hematological data of 9 cases with factor XIII deficiency is highlighted. The age at first bleed ranged from 3 days of life to 1 year. Seven of these 9 cases had bleeding from the umbilicus, 3 had recurrent subcutaneous and muscle hematomas, while 4 cases had CNS bleeds of which 3 expired. Routine coagulogram was normal, while clot solubility in 5 molar urea solution was abnormal in all cases. Factor XIII assay was not done in any. Patients were treated with plasma transfusion during episodes of bleeding. No patient received plasma transfusion as prophylactic therapy. The cumulative Indian data so far documented, inclusive of this series, shows a very high incidence of CNS bleeds (33%) in patients with this inherited coagulation disorder.
