Study of some immunological indicators in women infected with toxoplasma gondii in mesan province

Toxoplasma gondii is an obligate intracellular parasite capable of infecting humans. In the vast majority of cases in healthy adults, toxoplasmosis is typically not accompanied by any symptoms. However, the infection has the potential for serious consequences in immunocompromised people and pregnant women. Unplanned pregnancies, stillbirths and birth abnormalities are possible consequences of foetal toxoplasmosis, especially in early pregnancy. Infected babies may not develop any disease, but depending on the gestational age of the baby, serious damage to the brain and eyes may occur to a certain extent. The immune system is responsible for destroying bradyzoites, which are hidden cysts released from the tissue, as well as preventing the parasites from multiplying. On the other hand, if a woman becomes infected with tachyzoites during pregnancy, the tachyzoites can cross the placenta and cause disease in the foetus. There are a number of variables that influence the progression of an infection and the symptoms it causes. These include implantation factors, the virulence of the specific microbe, the stage of pregnancy at the time of infection, genetic characteristics and the immunological status of both mother and foetus. It is important that pro-inflammatory T-helper 1 cytokines are present throughout the early stages of normal pregnancies to stimulate vasculo-genesis, which is crucial for successful implantation of the embryo. On the other hand, continuous exposure to T-helper 1 cytokines can result in a cell-mediated immune response that is detrimental to the foetus and can lead to pregnancy loss. Therefore, a switch to anti-inflammatory T helper 2 immunity is often seen in the final stages of successful pregnancies. The correct homeostatic balance of T helper 1 and 2 cytokines is extremely important when it comes to the stable maintenance of pregnancy and other reproductive events. It has been discovered that pregnancies that are considered normal are generally accompanied by higher expression of T helper 2 cytokines, whereas pregnancies associated with unfavourable outcomes are usually associated with higher T helper 1 cytokine production. Serological diagnosis is the most commonly used method to determine the stage of a current, new or previous infection. The findings of these tests can be ambiguous, although they have a high degree of sensitivity. Molecular direction is crucial for finding T. gondii DNA with the B1 repetitive motif, which has been shown to be more sensitive than other iv targets. This is likely to be due to B1 being a DNA sequence that is repeated and has a higher copy number. This study involved 180 female participants who were divided into two groups. The first group consisted of 90 women diagnosed with Toxoplasmosis infection, while the second group consisted of 90 apparently healthy and age-matched women. About 5 mL of venous whole blood was collected from each participant and divided into two parts. Up to 2 mL was poured into a tube containing anticoagulant factor, while the remaining 3 mL was poured into a tube without anticoagulant factor. Anti Toxoplasma IgM and Anti-Toxoplasma IgM, interleukin-10, interleukin-23 and tumour necrosis factor-α were measured using immunoassay technique. Nested polymerase chain reaction was used to detect T. gondii B1 gene. The age range was 17-40 years. Anti Toxoplasma IgG and IgM antibodies, interleukin-10, interleukin-23 and tumour necrosis factor-α serum levels were higher in women with toxoplasmosis compared to healthy women and significant differences (p value <0.001) were found between both groups. B1 gene was positive in 32 women (35.56%) and negative in 58 women (64.44%). A significant difference was found in serum Anti-Toxoplasma IgG antibody according to B1 gene (p value <0.001), while no significant difference was found in Anti-Toxoplasma IgM antibody (p value 0.910). Furthermore, there was a positive correlation between serum Anti-Toxoplasma IgG antibody and interleukin-10 (r=290). Toxoplasmosis can develop at any age; however, according to our study, young women are more susceptible to infection. The high levels of Anti-Toxoplasma suggest that antibodies play an important role in defence against acute and reactivated infections. High levels of interleukin-10, interleukin-23 and tumour necrosis factor-α among infected women suggest that toxoplasmosis may stimulate an adaptive immune response in both anti- and pro-inflammatory diseases to protect and prevent immunological effects on host tissues. The positive correlation between Anti-Toxoplasma IgG antibody and interleukin-10 indicated that these markers play an important role in clearing the infection and limiting immune response effects on host tissues.
