Henci (and any others they may be able to shed light)-
I am a doula currently working on my bachelor's in nursing to eventually become a CNM and attend homebirths after my indentured servitude is up. I would like to know if there is any valid data (studies or clinical trials) that show that probiotic supplementation through the diet or using probiotic preparations directly on or in the vagina will prevent GBS colonization. I read blogs about stillbirth often because it is what I most fear about becoming a midwife and there seems to be some evidence that 4-10 percent of unexplained stillbirth may actually be caused by intrauterine infections caused by GBS.
In my reading of these blogs I came across a particularly well educated woman with a science background of some kind that was pregnant after stillbirth. An intrauterine GBS infection with an intact bag of waters played a role in the death of her baby and she and her doctor had layed out a plan to do monthly GBS tests throughout the pregnancy, treating with antibiotics anytime GBS was detected. Another person commented that the antibiotics may cause the GBS colonization to worsen and suggested a daily intake of probiotic foods and/or a probiotic supplement to prevent colonization.
To this suggestion the pregnant woman replied that there was no evidence that probiotics could help suppress GBS colonization and that the commenter was mistaken. The commenter posted back with a few different Pubmed abstracts that related to GBS suppression with different applications of probiotics. I will post a link to this whole discussion (I found it interesting). What I'm wondering is if it is yet known scientifically whether or not probiotics will actually prevent or suppress GBS colonization. The pregnant woman with a science background did not seem to think that any of the studies showed probiotics could be beneficial in this application. Here is a link to the site where I read about all of this. I thank anyone who can shed some light on this for me. I will suggest daily probiotic use to all my pregnant clients if this is the case.
