摘要

Gulf War Illness (GWI) affects 32% of Veterans from the 1990–1991 Gulf War. It is characterized by fatigue, mood disturbances, pain and cognitive decrements, with no FDA-approved treatment. This exploratory randomized, double-blind, placebo-controlled trial evaluated the safety and efficacy of oleoylethanolamide (OEA) supplementation in 52 Veterans with GWI (mean age 59 ± 5 SD, 94% males and 79% White). Participants received 200 mg of OEA twice daily or a matching placebo for 10 weeks, followed by a 5-week open-label OEA extension. Outcomes included the Multidimensional Fatigue Inventory (MFI-20), abbreviated Profile of Mood States (POMS), Short-Form McGill Pain Questionnaire, Veterans RAND 36-Item Health Survey (SF-36 V), Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and CNS Vital Signs Test, administered at baseline and 10- and 15-weeks. A main effect of OEA for reducing fatigue (MFI-20, p ≤ 0.05) and improving the total mood disturbances score (POMS, p ≤ 0.05) was observed. Participants on OEA reported increased energy, emotional well-being, and social functioning (SF-36 V, p ≤ 0.05). No changes were seen in cognitive performance or pain. Oleoylethanolamide was well-tolerated with no serious adverse events. In summary, OEA was safe and improved fatigue and mood in Veterans with GWI. Larger trials are needed to confirm these benefits.
