The Status of Thrombophilic Defects and Non-O Blood Group as Risk Factors for Gestational Vascular Complications among Tunisian Women.
Summary of "The Status of Thrombophilic Defects and Non-O Blood Group as Risk Factors for Gestational Vascular Complications among Tunisian Women."
Aims: Our objectives were to assess inherited thrombophilia and non-O blood group for the risk of gestational vascular complications among the Tunisian population. Methods: This study comprised 203 test subjects with adverse pregnancy outcomes including recurrent pregnancy loss, intra-uterine growth retardation, pre-eclampsia and placental abruption. Each subgroup was matched with 100 controls and analyzed separately. All patients were evaluated for factor V Leiden, factor II G20210A mutations and for non-O blood group. Protein S, protein C and antithrombin levels were determined and deficiencies noted. Results: The factor V Leiden mutation, non-O blood group and protein C deficiency had the highest incidences among patients both as a whole and in the 4 subgroups. The factor II G20210A mutation, protein S and antithrombin deficiencies were not statistically significant risk factors. Conclusion: Our results provide evidence for a significant association between the factor V mutation and placental abruption. Furthermore, we found that this and the non-O blood group independently increased the risk for intra-uterine growth retardation in our population.

Lewis Blood-group System
A group of dominantly and independently inherited antigens associated with the ABO blood factors. They are glycolipids present in plasma and secretions that may adhere to the erythrocytes. The phenotype Le(b) is the result of the interaction of the Le gene Le(a) with the genes for the ABO blood groups.
The relating of causes to the effects they produce. Causes are termed necessary when they must always precede an effect and sufficient when they initiate or produce an effect. Any of several factors may be associated with the potential disease causation or outcome, including predisposing factors, enabling factors, precipitating factors, reinforcing factors, and risk factors.
Pregnancy in which the mother and/or FETUS are at greater than normal risk of MORBIDITY or MORTALITY. Causes include inadequate PRENATAL CARE, previous obstetrical history (ABORTION, SPONTANEOUS), pre-existing maternal disease, pregnancy-induced disease (GESTATIONAL HYPERTENSION), and MULTIPLE PREGNANCY, as well as advanced maternal age above 35.
The procedure established to evaluate the health status and risk factors of the potential DONORS of biological materials. Donors are selected based on the principles that their health will not be compromised in the process, and the donated materials, such as TISSUES or organs, are safe for reuse in the recipients.
Agents that cause agglutination of red blood cells. They include antibodies, blood group antigens, lectins, autoimmune factors, bacterial, viral, or parasitic blood agglutinins, etc.
