The relationship between the helicobacter pylori seropositivity with systemic and local oxidative status and hyperemesis gravidarum: a pilot study

Abstract

Objectives: The aim of study was to determine the helicobacter pylori (HP) seropositivity and oxidative parameters in serum and saliva of pregnant women with poor oral hygiene and hyperemesis gravidarum (HG).

Methods: A case-control study was conducted involving 50 pregnant women in their first trimester of pregnancy. Twenty-five subjects had a diagnosis of HG, and remaining 25 were healthy pregnant women who served as control subjects were included. The groups were adjusted for age, parity and gestational week. All patients were subjected to the measurement of total oxidant status (TOS) and total antioxidant status in serum and saliva. Also HP seropositivity was investigated.

Results: Serum TAS and TOS values were similar, although oxidative burden in saliva of women with HG were significantly higher than controls. HP seropositivity was found to be 24% in women with HG and 4% of controls.

Conclusions: Our results suggest that significantly increased oxidative burden and slightly decreased antioxidative capacity of saliva may be involved in the pathogenesis of HG and this condition may be the result of HP infection which was found to be significantly more common in women with poor oral hygiene and HG.
