Özet

Aim: Toxoplasmosis in pregnancy may cause ophthalmologic and neurological sequelae in the fetus. However, this screening is not clearly included in routine screening protocols in our country. Therefore, there is no general information about the exact prevalence of the disease. In this study, it was aimed to evaluate the toxoplasmosis seroprevalence studies conducted in Turkey during pregnancy using the pool analysis method and to highlight the difference in disease seroprevalence between regions. Material and Method: Published literature in English and Turkish language on toxoplasmosis seroprevalence in pregnancy from Turkey in last 30 years were elavuated. Four international databaseses were scanned by using the keywords "Toxoplasmosis" OR "Toxoplasma gondii" OR "TORCH" and "seroprevalence" OR "IG G" and"pregnant women" OR "pregnancy" OR "pregnant" and ''Turkey'' or 'Turkish'. The publications were evaluated in terms of the general frequency, city, region, year, sample size, diagnostic method. Conference papers were not included in the study. Studies involving refugee women in the sample group were excluded. Results: A total number of 58 studies and 256612 test results were included. ELISA (n=22) was the most preferred laboratory diagnostic method. The average Anti-Toxo IgG seroprevalence rate in the pregnant population in Turkey was found to be 36.76%. And the average of Anti-Toxo IgM rate was found to be 2.91%. As a result of our study, the highest Anti-Toxo IgG test results were; It was found in studies conducted in Southeastern Anatolia (59.43%), Mediterranean (43.95%) and Eastern Anatolia (40.89%). The regions with the lowest Anti-Toxo IgG test results are respectively; Aegean Region (30.25%), Marmara Region (31.21%) and Black Sea Region (31.80%). Anti-Toxo IgM ratios are highest respectively; It was detected in Aegean Region (5.65%), Mediterranean Region (2.77%) and Southeastern Anatolia (2.21%). Conclusion: It has been determined that western Turkey (Aegean Region) is riskier in terms of congenital toxoplasmosis due to its high susceptibility to Toxoplasma infection associated with low toxoplasma seroprevalence compared to the east, and it is considered important to perform at least region-based prenatal toxoplasma screening to prevent this
