Peri-conception Nematode Parasitosis Is an Ecological Problem but Solely Is Not a Risk for Complicated Pregnancy

Background: Nematodes represent a continuous worldwide challenge with formidable burden on health and economics. Objective: The study aimed to assess the prevalence of nematodes parasitosis (NP) among pregnant women and its relation to the pregnancy-associated complications (PACs). Patients and Methods : In the current study 792 pregnant women were clinically evaluated and gave blood samples and three stool specimens per woman for parasitological evaluation. All women attended the follow-up visits and gave labor at the hospital. The frequency of PACs was determined and its relation to NP was examined statistically. Results: Multiple nematode species were detected in 185 specimens with A. lumbricoides, E. vermicularis, and T. trichiura represented 76.2% of the detected parasites in varied combinations, while T. spiralis was the least and was detected using human anti-trichinella spiralis IgG ELISA kit. The incidence of PACs was significantly higher among infected women with anemia was the commonest. The frequency of low hemoglobin concentration (HBC) was significantly higher, the average HBC was significantly lower, and the frequency of moderate and severe anemia was significantly higher among the infected women. The number of women who had instrumentally aided vaginal delivery or operative delivery was significantly higher among infected women. Conclusion : Nematode parasitosis is an ecological problem and is frequent among pregnant women especially those dependent on outdoor food staffs. Multiple-families NP is significant predictor for upcoming PACs. NP in obese pregnant women especially older ones has more deleterious impact on pregnancy.
