ABSTRACT
This study was performed to evaluate the level of anti-toxoplasma antibodies among patients with miscarriage due to different causes as compared to un-complicated pregnant controls. It was carried out on 70 female patients with a history of complicated pregnancies and 30 ones with normal pregnancy as a control were selected, among those referred from Obstetrics and Gynaecology out-patient clinics and in-patient departments, AL-Azhar University Hospitals. Their ages ranged from 19 to 34 years . They were all Rh positive and free from brucellosis, syphilis and malignancy. Results showed that all controls [uncomplicated pregnancy] were IHA-IgG and ELISA-IgM negative. However, three of the controls [10%] were ELISA. IgG positive. As to the women with complicated pregnancy 59% were IHAT positive. When using ELISA, 57% were IgG positive and 43% were IgM positive. The results revealed a significant difference between the complicated cases and controls. The diagnosis of abortion, stillbirth, premature labour, or neonatal death due to toxoplasma infection needs careful and laborious evaluation. ELISA [IgG and IgM] is more sensitive and specific than IHAT. All premature born babies showed no signs of congenital toxoplasmosis. All these subjects were living in the same geographical area with more or less similar social and economical standard
