Helicobacter pylori infection, gestational diabetes mellitus and insulin resistance among pregnant Sudanese women

Abstract

Abstract Objectives To assess the association between Helicobacter pylori (H. pylori) infection and insulin resistance among pregnant Sudanese women attending Saad Abuelela hospital (Khartoum). A cross-sectional study was conducted from 1st July 2017 to 31st January 2018. One hundred and sixty-six women were enrolled and underwent testing for H. pylori IgG antibodies using specific ELISA kits. The Quantitative insulin sensitivity check index (QUICKI) was computed from the fasting insulin and glucose levels. Results Median age, gravidity and gestational age were 27 years, 2 and 26 weeks, respectively. Twenty (12%) women were found to have gestational diabetes mellitus (GDM). H. pylori IgG seroprevalence was 66.0% among the study population. Univariate analysis showed that H. pylori-seropositivity was significantly higher among women who have GDM while Log (Homeostatic Model Assessment-β) HOMA-B% was lower (P value = 0.038, and 0.028) respectively. There was no difference between the GDM group and the other group in terms of demographics, body mass index, haemoglobin and QUICKI index results. In multivariate analysis, a higher prevalence of H. pylori was associated with GDM (OR = 2.8, 95% CI 1.1–7.5, P = 0.036). The current study concludes that an increased prevalence of H. pylori is a risk factor for the development of GDM.
