Seroprevalence of toxoplasmosis in diabetic pregnant women in southwestern of Iran.

To investigate anti-Toxoplasma gondii IgG and IgM antibodies in diabetic pregnant women in Ahvaz, southwest of Iran this experiment was performed. In current study the sera of 110 diabetic pregnant women as well as 110 non diabetic pregnant women referred to the hospitals affiliated with the Ahvaz Jundishapur University of Medical Sciences were assessed for anti-T. gondii IgG and IgM antibodies by ELISA and IFA methods. The ELISA assessments showed that 47 (42.7 %) and 3 (2.7 %) of diabetic women were positive for IgG and IgM antibodies, respectively. However, in the control group, 24 individuals (21.81 %) were positive for IgG antibody but no detection for IgM antibody. According to IFA method, 46 (41.8 %) and 3 (2.7 %) of diabetic women were positive for IgG and IgM antibodies, respectively, while in control group, 21 individuals (19.09 %) were positive for IgG antibody. In this method, IgM antibody was negative for all samples of control group (0 %). In both methods, the values obtained in the case group were significantly higher than those in the control group (p < 0.05). Prevalence of anti-Toxoplasma IgG and IgM antibodies in diabetic pregnant women was higher than that in non-diabetic pregnant women. It seems that screening tests for seeking patients and teaching the transmission routes should be considered as prenatal cares for diabetic women.
