Genotyping and evaluation of interleukin-10 and soluble HLA-G in abortion due to toxoplasmosis and HSV-2 infections.

Abortion is a condition that occurs due to one of the pathological injuries, often one of the members of the TORCH is the real cause. The current study aimed to investigate the impact of toxoplasmosis, HSV-2 infections with abortion, and also, the identification of immunogenetics marker (interleukin-10) that may be associated with abortion. Anti-Toxoplasma IgG, IgM, Herpes simplex virus-2 IgM, human soluble leukocyte antigen class I-G and interleukin-10 were estimated by ELISA technique, while the expression of IL-10 gene was investigated by using the real-time PCR. The results showed that among aborted women the rate of anti-Toxoplasma and HSV-2 IgM antibodies occurred within the age groups (21-30) years and (31-40) years 32(100.0%) and 36(100.0% ), respectively. A significant relationship was found between IL-10 and cases with a P=0.005. The pattern of distribution of HLA-G in the studied groups showed that there was a significant relationship between HLA-G and cases with a P=0.005. Regarding the IL-10 rs gene, the results revealed an amplified product of 377 bp and there was a high Ct value for patients and controls with a high Ct value of templates, preoperational to the gene concentration. We concluded that there was a significant relationship between human leukocyte antigen-G and the cases. It was found that there was a high Ct value for patients and controls with a high Ct value for templates.
