The bill would have made the RAC an independent organization within the VA, require that a majority of the RACs members be appointed by Congress instead of the VA, and authorized the RAC to release its reports without needing prior approval from the VA Secretary. The RAC is responsible for investigating Gulf War illness, a chronic multisymptom disorder affecting returning military veterans of the 1990–91 Gulf War.In the year prior to the consideration of this bill, the VA and the RAC were at odds with one another. The VA replaced all but one of the members of the RAC, removed some of their supervisory tasks, tried to influence the board to decide that stress, rather than biology was the cause of Gulf War illness, and told the RAC that it could not publish reports without permission. The RAC was created after Congress decided that the VAs research into the issue was flawed, and focused on psychological causes, while mostly ignoring biological ones.The RAC was first authorized under the Veterans Programs Enhancement Act of 1998 (Section 104 of Public Law 105–368, enacted November 11, 1998, and now codified as 38 U.S.C. § 527 note). While the law directing its creation mandated that it be established not later than January 1, 1999, the RACs first charter was not issued until January 23, 2002, by VA Secretary Anthony Principi. The RAC convened for its first meetings on April 11–12, 2002.
Current studies funded by the GWIRP and the VA are also investigating yoga as a treatment for GWI. An amino acid supplement containing L-carnosine was found to reduce irritable bowel syndrome-associated diarrhea in a randomized, controlled GWIRP-funded trial in GW Veterans (Baraniuk, 2013). Veterans receiving L-carnosine showed a significant improvement in performance in a cognitive task, but no improvement in fatigue, pain, hyperalgesia, or activity levels. Results from a 26 week GWIRP-funded trial comparing standard care to nasal irrigation with either saline or a xylitol solution revealed that both irrigation protocols reduced GWI respiratory (chronic rhinosinusitis) and fatigue symptoms (Hayer, 2015). Administration of the glucocorticoid receptor antagonist mifepristone to GW Veterans in a GWIRP-funded randomized trial resulted in an improvement in verbal learning, but no improvement in self-reported physical health or other self-reported measures of mental health (Golier, 2016).Ongoing Intervention Studies
The GWIRP is currently funding many early-phase clinical trials aimed at GWI. Interventions include direct electrical nerve stimulation, repurposing FDA-approved pharmaceuticals, and dietary protocols and/or nutraceuticals. Both ongoing and closed GWIRP-supported clinical treatment trials and pilot studies can be found at [1]. A Clinical Consortium Award was offered [in FY2017] to support a group of institutions, coordinated through an Operations Center that will conceive, design, develop, and conduct collaborative Phase I and II clinical evaluations of promising therapeutic agents for the management or treatment of GWI. These mechanisms were designed to build on the achievements of the previously established consortia and to further promote collaboration and resource sharing.
