Background: Hyperemesis gravidarum (HG) starts between four and seven weeks after the first day of the last period, and ends at twenty weeks of pregnancy. The etiology of HG, is unknown. Recent studies worldwide show the Helicobacter pylori (H. pylori) infection as a possible cause of the severe nausea and vomiting in pregnancy, recent studies showed H. pylori to have a role in occurrence of it during pregnancy. The current study assessed the immunoglobulin G (IgG) and immunoglobulin M (IgM) titer to H. pylori in pregnant women with HG. Methods: This is a case-control study of the pregnant patients of a gynecologist's office in the Marvdasht city from April to September 2013. One hundred and twenty three patients were randomly chosen based on their conditions and were divided into two groups (case n1= sixty three and control n0= sixty). The IgG and IgM titers against H. pylori were measured by ELISA method. Data analysis was performed using Chi-square test, Mann-Whitney U-test, and T-test in SPSS software, version 20 (SPSS, Inc., Chicago, IL, USA). The significant level of the test was considered (P= 0.05). Results: Totally, 123 pregnant women were evaluated 63 women with hypermesis gravidarum and 60 without HG. Forty nine women out of 63 in HG group and 48 women in the control group were IgG positive for H. pylori. Also, mean serum level of IgG was 51.6 in the HG group (P= 0.685). Twelve women out of 63 in HG group and 20 women in the control group were IgM positive for HP. Also, mean serum level of IgM was 27.7 in the HG group (P= 0.675) Except for the mother's blood type, there were no other statistically significant differences found between the two types of antibodies against H. pylori. Conclusion: There is no relationship between helicobacter pylori and hyperemesis gravidarum in pregnant woman. Considering the high prevalence of H. pylori infection in our country, there is a need for studies with more samples and more diagnostic methods.
