Objective:
In this study, it was aimed to retrospectively evaluate the anti-Toxoplasma IgG, IgM and avidity index results of patients who were requested for Toxoplasma serology in our hospital between 01.01.2017 and 31.12.2021.
Methods:
Anti-Toxoplasma antibodies are studied with Abbott Architect İ2000 SR device that using the chemiluminescent microparticle immunoassay method (CMIA), according to the company's recommendations. The age, gender, nationality, sending clinic/polyclinic, and pregnancy status information of patients were scanned from the hospital system.
Results:
In the five-year period between 2017 and 2021, 29.58% of anti-Toxoplasma IgG tests requested from 12694 patients and 0.94% of anti-Toxoplasma IgM tests sent from 12546 patients were found positive. It is striking that the number of test requests is higher in women. IgG positivity is highest in women in the age group of 30-39 (9.97%), and in men in the age group of 60-69 (6.97%). IgM positivity is higher in both women and men in the 20-29 age group (0.48% and 0.38%, respectively). Anti-Toxoplasma IgG was positive in 27.78% and IgM in 0.64% of the pregnant women. IgG positivity in Turkish and Syrian pregnant women were determined as 25.88%; 47.10% and IgM positivity as 0.49% and 1.83%, respectively, and the difference was statistically significant (p<0.001).
Conclusion:
Our anti-Toxoplasma antibody positivity was found to be compatible with studies conducted in different centers in our country. The fact that IgM positivity in women is high in the 20-29 age group, which is the childbearing age, emphasizes the importance of screening before and during pregnancy. Consistent with other studies in the literature, the rate of seropositivity in Syrian pregnant women was found to be higher than Turkish. This is important in terms of showing the effect of socio-cultural behaviors on prevalence.
