Background: Helicobacter pylori and Chlamydia trachomatis infections are associated with many complications of pregnancy including preeclampsia. The association between H. pylori and C. trachomatis with preeclampsia needs to be further explored.Methods: A case-control study was conducted at Saad Abualila Hospital, Khartoum, Sudan during the period of February to August 2015 to investigate the association between H. pylori or C. trachomatis with preeclampsia. The cases were women with preeclampsia and healthy pregnant women were the controls. The obstetrics and clinical history were gathered using questionnaires. Weight and height were measured and were used to compute body mass index (BMI). H. pylori and C. trachomatis antibodies (IgG) were determined by their specific enzyme-linked immunosorbent assays (ELISAs), respectively.Results: There was no significant difference in the age, parity, gestational age, BMI, and hemoglobin between the two groups (93 women in each arm). In all, 31 and 62 cases were severe and mild preeclampsia, respectively. H. pylori seropositivity (IgG) was significantly higher in the preeclamptic women compared with their respective controls (80/93 [86.0%] versus 52/93 [55.9%], p < 0.001). In binary logistic regression, H. pylori seropositivity (adjusted odds ratio [AOR] = 4.933, 95% confidence interval [CI] = 2.082-11.692) was associated with preeclampsia. No C. trachomatis seropositive women were detected in the studied subjects.Conclusion: The current study confirmed that H. pylori, but not C. trachomatis, is associated with preeclampsia.
