[Impact of Toxoplasma gondii infection on pregnancy outcomes in early pregnant women].

OBJECTIVE

To explore the impact of Toxoplasma gondii infection on pregnancy outcomes in early pregnancy women.

METHODS

Toxoplasma gondii IgM and IgG antibodies in the peripheral blood of 2 993 early pregnant women were detected by using enzyme-linked immunosorbent assay (ELISA). According to the test results, the infected ones were divided into an acute infection group, a previous infection group, and an active infection group, and 200 pregnant women without Toxoplasma infection were randomly chosen as a control group, and the pregnancy outcomes of the four groups were followed up and the results were compared.

RESULTS

There were 286 women infected with Toxoplasma gondii, with the infection rate of 9.56% (286/2 993), in which 43 cases were diagnosed as acute infection, 156 were previous cases, and the other 87 were active infection ones. The incidences of adverse pregnancy outcomes in the above 3 groups and the control group were 13.95% (6/43), 1.92% (3/156), 5.75% (5/87) and 1.50% (3/200), respectively. The incidences of adverse pregnancy outcomes in the acute infection group and active infection group were both higher than that in the control group, the differences were statistically significant (both P < 0.05), while there was no significant difference between the previous infection group and control group (P > 0.05).

CONCLUSION

Acute and active Toxoplasma gondii infections are closely associated with the occurrence of adverse pregnancy outcomes in early pregnant women; therefore, Toxoplasma gondii IgM antibody should be included in the routine inspection items of the pre-pregnancy physical examination for child-bearing age women.
