Toxoplasmosis and habitual abortion

We set out to determine the role of toxoplasmosis, detected by serological tests, in habitual abortion. A total of 280 pregnant women aged 15-46 years with parity ranged from 0-9 were studied prospectively between January 2000 and May 2001 at King Hussein Medical Center. Analyses for IgG and IgM anti-toxoplasma were carried out using indirect fluorescent antibody assay (IFAT) and enzyme-linked immunosorbent assay (ELISA). Titres of the order of 1:16-1:2048 were considered positive. According to the results, women were divided into two groups; seropositive (n=132) and seronegative (n=148). One hundred and thirty-two (47.1%) pregnant women showed seropositivity to IgG anti-toxoplasma; of them, two (1.5%) developed IgM anti-toxoplasma during the second trimester. A statistically significant increase in the rate of seropositivity to toxoplasma with increasing age and parity was found (P<0.05). There was no significant difference in the rate of habitual abortion between seropositive and seronegative women. The seropositivity was higher among women living in rural areas (P<0.02), who are using rainwater to drink (P<0.02), ingesting undercooked meat (P<0.001) and who have contact with soil (P<0.02). Toxoplasma antibodies detected by positive serological tests tend to be higher with increased age and parity. It seems that they have no role in habitual abortion.
