[Seroprevalence rates of Toxoplasma gondii, rubella, cytomegalovirus, syphilis, and hepatitis B, seroprevalences rate in the pregnant population in İstanbul].

Objective: We retrospectively evaluated the rate of Toxoplasma gondii, rubella, syphilis, cytomegalovirus, and hepatitis B in Istanbul to compare these results with those of other literature and to contribute to the national screening program.

Methods: The study was conducted in 2011 with women in the first trimester of pregnancy, with ages ranging between 16 and 48 years, in Bakırköy Training and Research Hospital's outpatient pregnancy clinic between January 2008 and January 2013. The mean age of pregnant women was 28.12±5.53, and the mean gravidity was 1.76+0.84.The seropositivities of T. gondii IgM and IgG, cytomegalovirus IgM and IgG, rubella IgM and IgG, VDRL (syphilis), HbsAg, anti-HBsAg were evaluated by ELISA method and evaluated in relation with age and parity.

Results: The seropositivity rates were as follows: T. gondii IgM: 0.8%, T. gondii IgG: 31.4%, cytomegalovirus IgM: 0.8%, cytomegalovirus IgG: 99.3%, rubella IgM: 0.2%, rubella IgG: 95.7%, VDRL: 0%, HbsAg: 1.2%, and anti-HbsAg: 26.3%. Also, pregnant women with T. gondii IgG(+) were older than pregnant women with T. gondii IgG(-), and this was statistically significant (p<0.005). Pregnant women with anti-HbsAg(+) were older than pregnant women with anti-HbsAg IgG(-), and this was statistically significant (p<0.005). Also, pregnant women with anti-HbsAg(+) had higher gravidity rates than pregnant women with anti-HbsAg(-), and this was statistically significant (p<0.005).

Conclusion: To protect from perinatally transmitted diseases, vaccination programs against rubella and hepatitis B should be extended, and educational programs including the whole country should be arranged. Screening of high-risk pregnant women will be more appropriate when considering the financial charges of screening programs performed for early detection of perinatal infections and for protecting the fetus.
