Relationship between Helicobacter pylori seropositivity and hyperemesis gravidarum with the use of questionnaire.

Aim. The aim of the present study was to investigate the relationship between Helicobacter pylori (HP) infection and Hyperemesis gravidarum (HG) by using a questionnaire. Methods. Twenty-five pregnant women with HG and 85 asymptomatic pregnant women (aged 14-40) of matching gestational age were enrolled between October 2004 and January 2006. Anti-HP immunoglobin G (IgG) serum antibody was tested to establish seropositivity. In our study we used a multi variable questionnaire (name, age, gravida, number of vomits daily etc.). The results were analyzed using Χ 2 and Mann-Whitney U- test. Results. The prevalence of HP infection was 56% (14 of 25) among patients with Hyperemesis gravidarum and 48.2% (41 of 85) among control subjects (P>0.05, Χ 2 test). In the same study the HP seropositivity is not related to age of the woman (50%, 55 of 110 were HP positive, P>0.05 Χ 2 test) but there was a significantly association between number of deliveries and HP seropositivity (primigravida [+] 34.2% versus 65.8%, multigravida [+] 6.1% versus 38.9%, P 0.05, Mann-Whitney U- test). Finally there was no relativity between the number of vomits daily and the HP seropositivity (48.2% with HP [+] and 0-3 vomits daily versus 56% with HP [+] and 4-8 vomits daily, P>0.05 Χ 2 ). Conclusions. Our findings do not support any direct correlation between HP seropositivity and Hyperemesis gravidarum, number of vomits daily, age of woman, history for gastrointestinal problems but only with the number of deliveries.
