Helicobacter pylori infection and platelet counts during pregnancy

To investigate whether there is any correlation between Helicobacter pylori infection and platelet counts during pregnancy. One hundred and twenty pregnant women without any complications were evaluated. Platelet counts were determined during pregnancy and postpartum. H. pylori infection was assessed by the detection of serum antibodies at the 3rd day postpartum. Statistically significant differences of platelet count between H. pylori-positive and -negative patients were determined. H. pylori infection was found in 29 of 120 (24.2%). Platelet counts in the 3rd trimester were 22.7±4.7×10 3/μl in H. pylori-positive group and 22.8±5.6×10 3/μl in negative group ( p=0.98). Platelet count in the 3rd trimester in positive and negative patients were 93±17% and 94±20%, respectively, of that of the 1st trimester ( p=0.92). The incidence of hyperemesis gravidarum in both groups was not significant ( p=0.28). A correlation between H. pylori infection and thrombocytopenia during pregnancy was not found in this study.
