ABSTRACT
Recurrent pregnancy loss is [RPL] a heterogeneous condition. While the role of acquired thrombophilia has been accepted as an etiology for RPL, the contribution of specific inherited thrombophilic gene polymorphisms to the disorder has been remained controversial. One hundred women with a history of two or more consecutive abortions and 100 women with at least two live births and no miscarriages were included in the study and evaluated for the presence of 11 thrombophilic gene polymorphisms [Factor V LEIDEN, Factor V 4070 A/G, Factor V 5279 A/G, Factor XIII 103 G/T, Factor XIII 614 A/T, Factor XIII 1694 C/T, PAI-1-675 4G/5G, ITGB3 1565 T/C, ?-Fibrinogen-455G/A, MTHFR 677 C/T, MTHFR 1298 A/C] using PCR-RFLP technique. The data were statistically analyzed using Mann-Whitney test and logistic regression model. There was no relation between factor XIII 103G/T gene polymorphism with increased risk of RPL. However, the other 10 gene polymorphisms were found to be associated with increased/decreased risk of RPL. Multiple logistic regression model for analyzing the simultaneous effects of these polymorphisms on the risk of RPL showed that six of these 11 polymorphisms [Factor V 1691G/A, Factor V 5279A/G, Factor XIII 614A/T, ?-Fibrinogen-455G/A, ITGB3 1565T/C, and MTHFR 1298A/C] were associated with RPL. It is possible to calculate the risk of abortion in a patient with RPL by determining only six of the 10 polymorphisms that are individually associated with RPL
ABSTRACT
Systemic lupus erythemathosus is an autoimmune disease that affected many various types of tissues in 10% of world population and over 30 genes has associated with it. Nouroimmunoendocrynology concepts have shown that immune system could be affected by neuron system and vice versa, 5-hydroxytryptamine receptor a [5HT3Ra] was studied as a main receptor in these relations. In this study, peripheral blood sample were collected from [SLE] patient and normal individuals. The total cellular RNAs were extracted and the cDNAs were synthesized. This process was followed by real-time PCR using specific primers for 5HT3Ra gene and beta-actin gene as internal control. Eventually PCR products have been sequenced. Results of this study suggested that this special receptor expressed in polymorpho-nuclear cells. We found over expression of 5HT3Ra in patients in comparison with healthy individuals group. Interestingly, some nucleotide changes have been found in 5HT3Ra gene in patients but not found sequential nucleotide changes in healthy individuals group. This study supposed that over expression of 5HT3Ra gene in SLE patients lead to over activation of immune cells that derived from over stimulation of them from serotonin blood serum that finally lead to autoimmune reactions that terminated in SLE
