Active clinical trials for "Persian Gulf Syndrome"

Low Dose Naltrexone (LDN) has been reported anecdotally to reduce the symptoms of Fibromyalgia, a Chronic Multisystem Illness. The drug may work by regulating natural pain-reducing systems. In this study, we will administer both LDN and placebo to a small group of individuals with Fibromyalgia and Gulf War Syndrome, both Chronic Multisymptom Illnesses, to assess the drug's efficacy in treating the condition.

This unblinded Phase II clinical trial tested the effects of individualized acupuncture treatments offered in extant acupuncture practices in the community; practitioners had at least 5 years of experience plus additional training provided by the study. Veterans with diagnosed symptoms of Gulf War Illness were randomized to either six months of biweekly acupuncture treatments (group 1, n=52) or 2 months of waitlist followed by weekly acupuncture treatments (group 2, n=52). Measurements were taken at baseline, 2, 4 and 6 months. The primary outcome is the SF-36 physical component scale score (SF-36P).

This study will provide symptomatic veterans with acupressure treatment and determine its effectiveness in fatigue relief and pain management for Gulf War Illness (GWI). Investigators plan to recruit patients reporting symptoms of GWI through the Department of Veterans Affairs (VA), and randomize them into acupressure group (to receive acupressure treatment) and control group (to receive Reiki treatment). The acupressure treatment, twice per week for 6 weeks, will be offered by a licensed acupressure practitioner. Evaluations will be made before and after treatment (at 6 weeks). Clinical outcomes will be compared between groups (acupressure group vs. control group) and between different timepoints (before treatment vs. after treatment) within the same group. The results of this study may provide useful information to develop more effective treatment for veterans with GWI disease. Since acupressure treatment is of Asian origin and has shown excellent promise within its Eastern traditions, if successful, this study has the potential to produce a paradigm shift in clinical practice to more effectively relieve the symptoms of veterans with GWI disease. Meanwhile, as a non-invasive therapeutic massage, acupressure may lend to better patient acceptance and ultimately, greater clinical accessibility. Hypotheses Acupressure besides routine clinical care will produce a more complete fatigue relief and pain alleviation in veterans with GWI versus routine clinical care plus reiki treatment. EEG measures will exhibit a positive change when fatigue is relieved and pain is alleviated for symptomatic veterans after effective treatment.

This trial is a study of Gulf War era veterans who have unexplained chronic medical symptoms such as pain, fatigue, and/or cognitive difficulties. The treatments to be studied, cognitive behavior therapy (CBT) and aerobic exercise, have been shown to be effective in alleviating symptoms in individuals with other similar types of illnesses, such as chronic fatigue syndrome and fibromyalgia. This is a Phase 3, 2X2 factorial designed study. All study participants are assigned to one of four treatment groups - CBT and aerobic exercise, aerobic exercise alone, CBT alone or usual and customary care. This study durations is 28 months; 1092 participants were enrolled and will be followed in clinic at 3, 6 and 12 months after enrollment.

The objective of the proposed research is to examine whether dietary exposure to food additives containing glutamate may be contributing to symptoms in Gulf War Illness (GWI). The rationale for proposed study comes from data in the fibromyalgia field which suggests that reducing the consumption of dietary glutamate can reduce over-excitation in the nervous system, leading to symptom improvement. In prior research, a low-glutamate diet (restricting food additive consumption) was tested in fibromyalgia patients. After one-month on the diet, 84% of patients had >30% of their symptoms go away (with 11 symptoms remitting on average), and 8 subjects had complete remission of all symptoms. Subjects then had a significant return of symptoms upon challenge with monosodium glutamate (MSG) as compared to placebo. Since there is almost complete symptom overlap between fibromyalgia and GWI, it is of utmost importance to test this diet as a low-cost treatment option in GWI patients. The findings from this research will ultimately be applicable to all GWI patients and potentially to other veterans with a similar symptom profile as well. The ultimate impact of this research could be quite profound, as it has the potential to impact all of the symptoms of GWI, as opposed to being a proposed treatment for only one of the symptoms. This dietary treatment has been shown to dramatically affect symptoms like fatigue, cognitive dysfunction, and pain; and thus, has the potential to dramatically improve quality of life for these individuals. Potential benefits of the treatment are great, and risks are minimal, as the treatment involves shifting the diet to a healthier, whole-food approach. First, the study will confirm or negate the idea that abnormal glutamate signaling in the nervous system could be causing symptoms in GWI. Second, if found to be successful, then this will provide a low-cost, easy-to-implement treatment option for the many veterans suffering from this multi-symptom illness. Third, this research could lead to future studies to identify potential causes of this abnormal neurotransmission, to help prevent future illness onset.

The purpose of this study is to determine whether nasal irrigation with Xylitol or saline are effective in the treatment of chronic rhinosinusitis and fatigue symptoms associated with Gulf War Illness.

The purpose of this study is to investigate clinical benefits of a novel sleep-focused mind-body program on Gulf War Illness (GWI) symptoms.

The purpose of this study is to perform a randomized double-blind, placebo-controlled, 12 week study of the effects of carnosine on cognitive, psychometric, autonomic, and muscle strength outcomes in 100 GWI subjects.

Up to one third of the 700,000 U.S. military veterans of the 1990-91 Gulf War have Gulf War Illness (GWI), a symptom complex characterized by a combination of chronic pain, cognitive impairment, debilitating fatigue, gastrointestinal complications, and other persistent symptoms. Epidemiologic studies of 1990-1991 Gulf War veterans have identified the short but intense combined exposure to insecticides (e.g., organophosphates, DEET, permethrin), pills with anti-nerve gas agent pyridostigmine bromide (PB), and low-level chemical nerve agents as likely candidates of GWI. Animal models have shown that these neurotoxicants could induce neuroinflammation which is marked by enhanced inflammatory cytokines, and activated microglia and astrocytes. Inflammation has been linked to GWI. Secondary effects of neuroinflammation and glia activation could be excessive glutamate-mediated neuronal activation. There is currently no treatment for symptoms of GWI. Ketamine is an N-methyl-D-aspartate receptor (NMDAR) antagonist. Besides blocking activation of NMDARs, a sub-anesthetic dose (0.5 mg/kg over 40 minutes) of ketamine could be an anti-inflammatory agent, and could protect microglia and astrocytes from being activated by inflammatory agents. This low dose of ketamine has also been shown to improve fatigue within 24 hours after a single infusion, and to improve inflammatory pain. This makes ketamine a feasible candidate for the treatment of inflammation-associated symptoms of GWI. This pilot study will examine if GWI is related to NMDAR functioning, testing effects of a single 40-minute intravenous infusion of 0.5 mg/kg of ketamine on GWI symptom severity in 21 veterans of the 1990-1991 Gulf War who meet Kansas case definition criteria of GWI.

This research project is a follow-up to the prior VA-funded study that found that chronic fatigue reported by many Gulf War veterans may be a symptom of dysfunctional cardiovascular stress response regulation. Specifically, ill veterans had diminished autonomic responses during demanding psychosocial tasks involving high level cognitive processing and emotional stress. There was a close relationship between clinical status of ill veterans and their inability to mount an appropriate physiological response under stress. The main objective of the present investigation is to determine the specific mechanism through which this abnormality may contribute to Gulf War-related chronic fatigue. We also observed that Gulf veterans with posttraumatic stress disorder (PTSD) had the most dampened autonomic activation to stressors involving higher brain activities. The second major focus of this study is to explore the role of a psychiatric disorder, specifically PTSD, as a factor in abnormalities in stress response regulation. This aspect of the study may also provide pertinent information as to the role of stress of military deployment as a contributing factor in post-Gulf War illnesses.
