The symptoms and risk factors of ME\/CFS share features of accelerated aging implicated in several diseases. Using<a href=\"https:\/\/en.wikipedia.org\/wiki\/Telomere\" target=\"_blank\" rel=\"noopener\"> telomere<\/a> length as a marker, this study was performed to test the hypothesis that ME\/CFS is associated with accelerated aging.<\/p>\n<p><strong>Methods:<\/strong><\/p>\n<p>Participant (n=639) data came from the follow-up time point of the Georgia CFS surveillance study. Using the 1994 CFS Research Case Definition with questionnaire-based subscale thresholds for fatigue, function, and symptoms, participants were classified into four illness groups: CFS if all criteria were met (n=64), CFS-X if CFS with exclusionary conditions (n=77), ISF (insufficient symptoms\/fatigue) if only some criteria were met regardless of exclusionary conditions (n=302), and NF (non-fatigued) if no criteria and no exclusionary conditions (n=196).<\/p>\n<p>Relative telomere length (T\/S ratio) was measured using DNA from whole blood and real-time PCR. General linear models were used to estimate the association of illness groups or T\/S ratio with demographics, biological measures and covariates with significance set at p&lt;0.05.<\/p>\n<p><strong>Results:<\/strong><\/p>\n<p>The mean T\/S ratio differed significantly by illness group (p=0.0017); the T\/S ratios in CFS (0.90 p\/m 0.03) and ISF (0.94 p\/m 0.02) were each significantly lower than in NF (1.06 p\/m 0.04). Differences in T\/S ratio by illness groups remained significant after adjustment for covariates of age, sex, body mass index, waist-hip ratio, post-exertional malaise and education attainment.<\/p>\n<p>Telomere length was shorter by 635, 254 and 424 base pairs in CFS, CFS-X and ISF, respectively, compared to NF. This shorter telomere length translates to roughly 10.1-20.5, 4.0-8.2 and 6.6-13.7 years of additional aging in CFS, CFS-X and ISF compared to NF respectively. Further, stratified analyses based on age and sex demonstrated that the association of ME\/CFS with short telomeres is largely moderated by female subjects&lt;45 years old.<\/p>\n<p><strong>Conclusions:<\/strong><\/p>\n<p>This study found a significant association of ME\/CFS with premature telomere attrition that is largely moderated by female subjects&lt;45 years old. Our results indicate that ME\/CFS could be included in the list of conditions associated with accelerated aging. Further work is needed to evaluate the functional significance of accelerated aging in ME\/CFS.<\/p>\n<p><strong>More info<\/strong>: <a href=\"https:\/\/solvecfs.org\/association-chronic-fatigue-syndrome-premature-telomere-attrition\/\" target=\"_blank\" rel=\"noopener\">The association of Chronic Fatigue Syndrome with premature telomere attrition<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research abstract: Association of chronic fatigue syndrome with premature telomere attrition, by Mangalathu S.
