简要总结
The aim of this study is to characterize the microbiome of patients undergoing post-acute residential neurorehabilitation compared to community controls and to determine if a dietary fiber, Inulin, can create a shift in the microbiome leading to changes in fatigue and cognition.
详细描述
The investigative research team previously described Brain Injury Associated Fatigue and Altered Cognition (BIAFAC) as a treatable syndrome that occurs in a subset of patients following traumatic brain injury (TBI). In addition to fatigue and brain fog, BIAFAC patients have altered growth hormone (GH) secretion, reduced serum amino acid levels, and an altered (dysbiotic) gut microbiome. GH treatment dramatically improves patient symptoms but is not curative; symptoms return when GH treatment ends and the associated gut dysbiosis is not corrected. In preliminary work with mouse models created using human fecal transplants from clinical BIAFAC subjects, transplanting the dysbiotic gut bacteria from BIAFAC patients alone caused fatigue, altered cognition, and dysregulated GH secretion without any trauma or head injury. These mouse models indicate that gut dysbiosis has a causative role in the development of BIAFAC by triggering both altered GH secretion and neurologic symptoms. In this clinical trial a dietary fiber, Inulin, will be administered to patients undergoing neurorehabilitation after brain injury to create a shift in their microbiome.
Specific Aims
Aim 1. Identify differences in blood and fecal microbiome biomarkers of neurorehabilitation patients.
Specific Aim 1a. Identify differences in blood and fecal microbiome biomarkers between patients entering an inpatient post-acute neurorehabilitation program and community controls.
Specific Aim 1b. Identify correlations between biomarkers (blood and fecal microbiome), demographics (e.g. age, sex), and clinical factors (e.g. medical history) of post-acute neurorehabilitation patients.
