Comparative study on the effect of factor V leiden and prothrombin gene polymorphism in preeclampsic cases

To identify polymorphism of Factor V Leiden and Prothrombin gene in women suffering from preeclampsia. From 142 pregnant women we identified 92 women suffering from preeclampsia and 50 healthy controls with normal pregnancy matched for age and socioeconomic status, preeclampsic patient classified as mild preeclampsia 42[45.7%] and severe preeclampsia 50[54.3%]. Blood samples were tested for DNA polymorphism affecting thrombophilia Factor V Leiden and Prothrombin gene polymorphism. Heterozygous AG genotype showed a significant high frequency among preeclampsic patients [20.7%] compared to controls [4.0%], [OR 6.2, P= 0.006] regarding to Prothrombin gene but: Factor V Leiden, AG genotype showed [8.7%] of preeclampsic patients which was absent in any of the controls

Comparative study on the effect of C667T and A1298C polymorphism in preeclampsic cases

To identify polymorphism of methylenetetrahydrofolate reductase gene in women suffering from preeclampsia. From 142 pregnant women we identify 92 women suffer from preeclampsia and 50 healthy controls with normal pregnancy matched for age and socioeconomic status, preeclampsic patient classified as mild preeclampsia 42[45.7%] and severe preeclampsia 50[54.3%]. Blood samples were tested for DNA polymorphism affecting thrombophilia methylenetetrahydrofolate reductase C677T and A1298C. Homozygous TT genotype, T allele of C677T polymorphism has a significantly higher frequency among preeclampsic cases compared to healthy controls [OR=21.7, 1.46, respectively]. Thus TT genotype and T allele may be considered as genetic risk factors for preeclampsic cases. On the other hand, non significant association in either genotype among preeclampsic cases compared to controls regarding to A1298C

PCR detection of Toxoplasma gondii DNA versus serological diagnosis in women suffering from repeated abortion

This study was conducted to test the utility of polymerase chain reaction [PCR] assay to detect recent infections with Toxoplasma in pregnant women. T.gondii DNA was detected by using B1 gene as a target for amplification which is highly specific for T.gondii and is well conserved among all of the tested strains. This study revealed the following findings:[l] PCR was positive in 63 subjects, including 58 high risk cases [77.3%] and 5 of controls [12.5%].[2] 17 high risk cases [24.6%] had false positive IgM and 5 of controls [12.5%] had false negative result for IgM. [3] 17 high risk cases [32.7%] had false positive IgG and 5 of controls [12.5%] had false negative IgG. [4] No significant association between eating raw meat or contact with cats and positive ELISA for PCR but there is highly significant association between women with contact with soil and positive PCR. [5] No significant relation between residency and either ELISA or PCR. [6] Significant negative correlation between the age of the studied women and positivity of PCR. this study highlights the need for a confirmatory test to detect primary acute toxoplasmosis in pregnant women. It demonstrates the possibility of defining and selecting the high-risk cases for mother-to-child transmission of infection by combining specific serology and PCR tests to formulate a specific approach
