Official title
Biological Signature and Safety of an Immunomodulatory Probiotic Intervention for Veterans With PTSD
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Exaggerated inflammation in the body and brain is thought to play a role in the vulnerability to and aggravation and perpetuation of adverse consequences among those with posttraumatic stress disorder (PTSD). The proposed study begins the process of investigating the use of a natural immunoregulatory/anti-inflammatory probiotic, Lactobacillus rhamnosus GG (LGG; ATCC53103), to treat chronic symptoms associated with PTSD among Veterans. By looking at the impact of probiotic supplementation on biological signatures of increased inflammation, as reflected by biomarkers of inflammation, gut microbiota composition, intestinal permeability, stress response, decision making, and PTSD symptoms, this study may identify a novel intervention for the treatment of symptoms associated with this frequently occurring condition.
