Toxoplasma gondii seropositivity and co-infection with TORCH pathogens in high-risk patients from Qatar

Author(s): Abu-Madi, MA (Abu-Madi, Marawan A.); Behnke, JM (Behnke, Jerzy M.); Dabritz, HA (Dabritz, Haydee A.)

Testing of patients who are deemed to be at high risk for TORCH pathogens, e.g., pregnant women, their fetuses, neonates, and acquired immunodeficiency syndrome (AIDS) patients, is important so that specific treatment can be initiated. This study included 1,857 such patients between 2005 and 2008. Logistic regression was used to evaluate factors associated with Toxoplasma gondii seropositivity. Among 823 women of childbearing age, 35.1% and 5.2% tested positive for T gondii IgG and IgM, respectively. Three infants 6 months of age (0.8% of 353) were congenitally infected. Factors associated with T gondii IgG seropositivity included older age, East Mediterranean or African nationality, positive cytomegalovirus (CMV) and herpes simplex virus (HSV)-1 serostatus, and negative rubella IgG results. The decreasing prevalence of IgM antibodies between 2005 and 2008 suggested that exposure to T gondii from food or environmental sources declined over this period in Qatar. Population-based studies of newborns would be helpful to accurately estimate incidence of congenital toxoplasmosis.
