Bacterial infections or even slight imbalances can be damaging at many difference locations in the human body. One that should be taken seriously in bacterial vaginosis, which is an infection in females where a healthy bacterial balance is taken over by bacteria such as Gardnerella vaginalis, Ureaplasma urealyticum, and Mycoplasma hominis to name a few. Meanwhile, the presence of Lactobacillus crispatus and Lactobacilus iners would be characteristic of a normal vaginal microbiome. In a study out of Philidelphia, Pa that was recently published by Maternal and Child Health Journal, researchers inspected a possible connection between bacterial vaginosis and pregnancy miscarriages.
A total of 418 pregnant women were included in the study. 65% of the women were African American, 27% were Hispanic, and 4% were Caucasian. Women were eligible if they were seeking treatment prior to 14 days of gestation, if they were not pregnant with multiples, and if there were no issues in terms of ectopic or molar pregnancy. Swabs were collected from the women and analyzed. During this study, 74 women experienced a miscarriage, while 344 delivered at term.
It was found that the group of women who had miscarriages were older than those who did not. Women with high concentrations of Bacterial Vaginosis-Associated Bacterium 3 (BVAB3) before 2 weeks gestation had a 20% increased chance of miscarriage. On the other hand, for each one unit increase in Leptotrichia/Sneathia species concentration, risk of miscarriage decreased by 20%, and for that of Megasphaera phylotype 1-like species risk decreased by 19%. The implications of this type of research could be very beneficial to women everywhere. More knowledge like this could hopefully one day lead doctors towards even better care for pregnant women. Ideally, with more research into this area, the prevalence of miscarriages could be lowered.
