Recurrent miscarriage can be defined as two or more consequence unsuccessful clinical pregnancies and confirmed by ultrasonography or histopathological examination and consider the most common clinical complications reproduction, and it affects (2%–5%) of reproduction couple. The present study included 140 women who were already diagnosed with recurrent miscarriage. Following complete clinical workup, including history, examination and investigations, enrolled women were classified into two main subgroups, explained group ( n = 85) and unexplained group ( n = 55). In this study, the result showed no significant difference found between the two subgroups explained and unexplained regarding age and the body mass index. In the obstetric history characteristics of women enrolled in the current study, there is no significant difference between the explained and unexplained group according to gravity, parity, and the number of abortions. Additionally, no significant difference according to gestational age and types of abortion but found significant in the type of complete abortion between the explained and unexplained group. Results showed that recurrent miscarriage rates increased in women with positive anti-phospholipids, in addition, a significant difference in the type of complete abortion between the explained and unexplained group of recurrent miscarriage women.
Background: Recurrent miscarriage and infertility are intriguing problems with growing clinical concern.Among the causes of thrombophilia; elevated plasma VIII:C activity level emerges with a rising concern as a possible risk factor of repeated miscarriage and subsequent infertility.Factor VIII is activated in the intrinsic pathway of coagulation cascade of secondary hemostasis. Objective: To evaluate plasma VIII: C activity level in females with repeated miscarriage and primary unexplained infertility in order to determine if Factor VIII:C over-activity is a probable cause of such conditions. Patients, Materials and Methods: This study was performed on strictly selected90 females, aged 20-45 year. The females wereassignedinto three groups (34 females with unexplained primary infertility, 41 females with history of repeated miscarriage(after exclusion of other gynecological and obstetrical causes) and 15 healthy age-matched females were selected as a control group. Plasma VIII:C functional activity was assayed.Blood samples for general hematological studies (Packed cell volume PCV, Prothrombin time PT, and activated partial thromboplastin time APTT) were obtained manually for all included females. C-reactive protein assayed in all samples to exclude the inflammatory causes of elevated factor VIII, which is regarded as an acute phase protein. Results: Factor VIII data were expressed as a mean of percentage of activity (±SD). A significant (*p=0.009) higher plasma activity level of factor VIII:C was demonstrated in infertile females(111.29%±31.66) and females with recurrent abortions (118.63%±39.54); Compared with the healthy control females (80.23%± 22.23), PCV, PT and PTT measurements demonstrated no statistical significance in infertile and recurrent abortion groups when compared to the control group (p>0.05). There was no statistically significant difference between the three groups regarding the PCV, PT and PTT measurement. Conclusions: Plasma Factor VIII:C activity level was higher in females with unexplained primary infertility and those with history of recurrent abortion. This elevation suggested of being independent risk factor of such conditions; after exclusion of other multiple causes leading to thrombophilia, abortion and infertility.
