摘要
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.
