Helicobacter pylori Seropositivity and Stool Antigen in Patients With Hyperemesis Gravidarum

Abstract

The objective of this paper is to investigate whether Helicobacter pylori is an etiologic factor in hyperemesis gravidarum. Thirty one patients with hyperemesis gravidarum and twenty nine pregnant controls without hyperemesis gravidarum were included in this prospective study. All pregnant women were examined both for Helicobacter pylori serum immunoglobulin G antibodies (HpIgG Ab), showing chronic infection, and Helicobacter pylori stool antigens (HpSA), showing active gastrointestinal colonization. Chi-square and Studentttests were used accordingly for statistical analysis. Helicobacter pylori seropositivity was67.7%in the patients with hyperemesis gravidarum and79.3%in the control group(χ2=1.02,P=.31). HpSA was detected in22.6%of patients with hyperemesis gravidarum, whereas6.9%of patients in the control group. The difference was not statistically significant(χ2=2.89,P=.08). In this study, no relation was found between Helicobacter pylori and hyperemesis gravidarum. The low social status of women in both groups could be one of the reasons for the high prevalence of Hp infection.
