Abstract

Helicobacter pylori (H. Pylori) is a gram-negative, flagellated and spiral-shaped bacterial pathogen that impacts approximately 46% among pregnant women globally and has been associated with various maternal-fetal complications. Iron deficiency anemia, fetal growth restriction, cardiovascular diseases, and insufficient nutrient absorption can be observed in pregnant women, as well as miscarriages and pregnancy-specific hypertensive disease, such as pre-eclampsia. Thus, the evidence supports the influence of H. pylori infection on fetal implantation/placentation failure, and positive strains of the cytotoxin-associated gene A of H. Pylori were reported as the most prevalent in these conditions. However, current knowledge indicates a relationship between this infection and the occurrence of hyperemesis gravidarum, characterized by frequent nausea and vomiting. Regarding the diagnosis of this bacterial infection, non-invasive approaches such as stool antigen test, urea breath test, and serological tests are more accepted during pregnancy, as they are easy to carry out and cost-effective. Finally, the bacteria eradication therapy should consider the risks and benefits for the pregnant woman and her child, with pharmacological intervention depending on the clinical presentation.

Core Tip:Helicobacter pylori infection during pregnancy is related to the development of disorders that may pose risks to maternal life and affect the proper development of the child. This bacterium has been associated with various complications such as hyperemesis gravidarum, iron deficiency anemia, pregnancy-specific hypertensive disease like pre-eclampsia, fetal growth restriction, and miscarriage. Therefore, this review provides a comprehensive overview of this condition, as well as its diagnosis and treatment, bringing together the most up-to-date information on the subject.
