Chronic fatigue syndrome and Gulf War veterans

14.05.2004


Chronic Fatigue Syndrome (CFS) is nearly four times as common in veterans of the first Persian Gulf War as in nonveterans, according to a new study. The study, to be published May 14, 2004 in the online edition of Muscle & Nerve, examined the possibility that genetic factors may play a role in developing the disease. The full study will be available via Wiley InterScience .



Fatigue that has no known medical cause, lasts more than six months, produces a substantial decrease of activity and is accompanied by symptoms associated with infection, as well as rheumatological, and neuropsychiatric symptoms, is known as CFS; idiopathic chronic fatigue (ICF) is fatigue without other symptoms or identifiable cause. CFS/ICF sometimes occurs in an almost epidemic fashion, such as in Gulf War veterans, but its cause is unknown. Genetic factors appear to play a role in both Gulf War veterans and civilian populations. Partial defects in one or more genes combined with environmental factors can result in conditions that include fatigue as a prominent feature. Previous studies have shown that mutations in the myoadenylate deaminase gene (AMPD1) and the carnitine palmitoyltransferase II (CPT2) gene can produce pain, stiffness, cramps or fatigue following strenuous exercise, while a genetic variant known as the insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme or ACE (DCP1) gene may impact performance and endurance in trained athletes and army recruits.

In this new study, Drs.Georgirene Vladutiu of the State University of New York at Buffalo and Benjamin Natelson of UMDNJ-New Jersey Medical School evaluated DNA from blood samples collected from 49 Gulf War veterans and 61 nonveterans with CFS/IFS and 30 veterans and 45 nonveterans who were healthy. Blood samples were analyzed for mutations in the AMPD1, DCP1, and CPT2 genes. No significant differences were found in variations of the AMPD1 and CPT2 genes in any of the four groups. However, Gulf War veterans with CFS/ICF showed a higher prevalence of the D variant in the DCP1 gene. Veterans with the DD genotype (which has been associated with alcoholism and cardiac disease) were 8 times more likely to develop CFS or ICF than those with the lower prevalence II genotype.


These results suggest that there may be an interaction between these genetic variants and some factor unique to deployment to the Persian Gulf. If they are supported by future research examining veterans of different wars and war zones, it may be that variants of the ACE gene could be a biological marker for increased risk of war-related illness.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
