Abstract
IntroductionOur purpose was to determine the bleeding risk of obligate and potential carriers, highlight the prophylactic applications before interventions for families and physicians. MethodForty-six sisters who had at least one family member with hemophilia A or B were included. Laboratory parameters were tested.Bleeding tendency interrogated by a detailed questionnaire.The results were compared with 43 healthy female controls. ResultsMean factor activity levels were significantly lower in sisters than control subjects (p = 0,004). Bleeding score was higher in sisters than controls (p = 0.001). Prolonged bleeding after minor injury was significantly higher in the sisters than control subjects (p = 0.008). Requiring further treatment due to prolonged bleeding after tooth extraction was significantly higher in sisters (p = 0.001). Sisters had postpartum hemorrhage lasting longer than 6 weeks than controls (p = 0.025). Menstrual period lasted longer in the sisters than controls (p < 0.001). Spontaneous epistaxis, oral and gingival bleeding were more frequently observed in sisters whose factor activity levels were 60 % or below (p = 0.014 and p = 0.047, respectively). There was no statistically significant difference between the severity of hemophilia in the affected family member and the factor levels in the sisters (p = 0.398).Spontaneous epistaxis has found to be significantly associated with the hemophilia severity in the family (p = 0.004). ConclusionClotting factor levels were found to be lower in the sisters and associated with spontaneous epistaxis, oral and gingival bleeding.Also, regardless of clotting factor levels, sisters significantly experienced more bleeding problems.Our study demonstrated the importance of taking precautions for prolonged bleeding in cases where medical interventions are inevitable in these patients.
