Seroprevalence of Anti-Toxoplasma gondii Antibodies and Associated Factors Among Pregnant Women Attending Antenatal Care at Debre Markos Referral Hospital, Northwest Ethiopia.

Abstract

BACKGROUND:

Toxoplasma gondii is an obligate intracellular protozoan parasite that causes a zoonotic disease called toxoplasmosis. If the infection acquired during pregnancy is not detected and treated early, the parasite can be transmitted transplacentally to the fetus, resulting in congenital toxoplasmosis, which likely leads to serious consequences in the fetus. Toxoplasmosis constitutes a major public health problem particularly in low- and middle-income countries including Ethiopia. This study aimed to determine the seroprevalence and to assess the potential risk factors of toxoplasmosis among pregnant women attending antenatal care at Debre Markos Referral Hospital, Northwest Ethiopia.

METHODS:

In this cross-sectional study, data on the sociodemographic and potential obstetric and behavioral risk factors were gathered through pretested structured questionnaires, and 3 mL of venous blood was also drawn from each of randomly selected 233 study subjects. The serum samples were separated from the blood samples and tested for anti-Toxoplasma antibody using Toxo-latex slide agglutination test. Logistic regression analysis was used to examine the association between risk factors considered and T gondii infection.

RESULTS:

The overall prevalence of T gondii infection was 67.8%, indicating a high prevalence of toxoplasmosis in the study area. In multivariate analysis, keeping domestic cat at home was found to be the only explanatory variable of toxoplasmosis (adjusted odds ratio = 2.449, 95% confidence interval = 1.183-5.070, P = .016). All sociodemographic variables and most of the potential obstetric and behavioral risk factors were not statistically significant explanatory variables of T gondii infection.

CONCLUSION:

The prevalence of toxoplasmosis is high in the study area. Thus, pregnant women should be aware of the potential risk of the disease when keeping cats at home and management of their litter. Inclusion of serologic screening for T gondii infection at antenatal care is warranted for prevention of congenital toxoplasmosis.
