|Brief Title ICMJE||Exercise and Behavioral Therapy Trial (EBT).|
|Official Title ICMJE||CSP#470 - A Randomized, Multi-Center, Controlled Trial of Multi-Modal Therapy in Veterans With Gulf War Illnesses|
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 primary hypothesis is that both aerobic exercise and cognitive behavioral therapy (CBT) will significantly improve physical function (as measured by the Physical Component Summary Scale of the SF-36V) in veterans with Gulf War Veterans' Illnesses (GWVI), and the combination of cognitive behavioral therapy and aerobic exercise will be more beneficial than either therapy alone.
Primary Outcomes: Improvement on the Physical Component Summary Scale of the SF-36V of more than 7 units at one year relative to baseline.
Interventions: Twelve one-hour weekly sessions of Cognitive behavioral therapy, aerobic exercise, the combination of the two therapies (12 one-hour sessions of CBT and 12 one-hour sessions of aerobic exercise) and a control group that receives usual and customary care.
Study Abstract: This trial was a study of Gulf War era veterans who have unexplained chronic medical symptoms such as pain, fatigue, and/or cognitive difficulties. All Gulf War veterans who were deployed to the South West Asia theater of operations between August 1990 and August 1991 were eligible for the study if they had at least two of the following three symptoms that began after August of 1990, lasting for more than six months and occurring up to present: 1. fatigue that limits usual activities (work, recreation, or social), 2. musculoskeletal pain involving two or more regions of the body, and neuro-cognitive dysfunction (self-reported difficulties in memory, concentration, or attention). Veterans who met enrollment criteria were randomized to one of four treatment arms: 1. CBT plus aerobic exercise, 2. aerobic exercise alone, 3. CBT alone, and 4. usual and customary care. Treatment was given for three months in group format. The CBT and exercise groups met for one hour, once a week for 12 weeks for a total of 12 hourly sessions. The interventions were standardized and all investigators were trained in the use of these methods prior to start up of the trial. The target sample size was 1064 veterans with GWVI to be accrued from 20 Medical Centers (18 VA and 2 DOD). All veterans were followed for one year and outcomes measured at 3 months (immediately following the end of treatment), 6 months and 12 months after enrollment.
The study was kicked-off in April 1999 and enrollment ended on September 5, 2000, during which 1092 veterans were randomized. Patient follow-up concluded on September 30, 2001 and the final DSMB meeting was held on November 28, 2001. The major finding was that there were no significant differences in the proportion of veterans who reported an improvement in physical function at one year among the treatment groups (11.5% for usual care, 11.7% for exercise, 18.4% for CBT and 18.5% for CBT + exercise). However, statistically significant improvements in fatigue, cognitive symptoms, distress, and mental health functioning were observed with exercise alone and with exercise plus CBT compared to usual care. CBT alone had a statistically significant effect on cognitive symptoms and in mental health functioning. Except for affective pain, which improved with CBT alone or with exercise, neither treatment had a significant effect on the other three measures of pain. In summary, neither exercise nor CBT had a significant impact on physical function for veterans with GWVI but both treatments, especially exercise, resulted in improvement in fatigue, cognitive symptoms, distress and mental health functioning.
