In this study, we evaluated a set of micro-RNAs as diagnostic biomarkers of pain intensity in adolescents with chronic fatigue syndrome (CFS). We then correlated the expression of these microRNAs with the levels of inflammatory markers and pain-related comorbidities in adolescents with CSF and healthy controls (HCs).<\/p>\n<p>METHODS:<\/p>\n<p>A total of 150 adolescents, aged 12-18 years, participated in this study between April 2016 and April 2017. The participants were classified into two groups: adolescents with CFS (n=100) and HCs (n=50). RT-PCR was used to evaluate the expression of miR-558, miR-146a, miR-150, miR-124, and miR-143. Immunoassay analysis was used to assess the levels of immune inflammatory markers IL-6, TNF-\u03b1, and COX-2.<\/p>\n<p>RESULTS:<\/p>\n<p>Adolescents with CFS showed significantly higher pain thresholds than comparable non-fatigued HCs. Also, enjoy of life and relation to others as the life domains, showed lower pain interference in CFS patients. Differential expression of miR-558, miR-146a, miR-150, miR-124, and miR-143 was significantly down regulated and notably interfered with pain intensity and frequency in patients with CFS. Also, the expression of these miRNAs was significantly correlated with that of IL-6, TNF-\u03b1, and COX-2, which have been shown to mediate pain intensity in patients with CFS.<\/p>\n<p>Girls with CSF showed significantly decreased expression levels of these miRNAs compared with the levels of boys with CSF. Girls with CSF also showed increased expression of inflammatory pain-related markers IL-6, TNF-\u03b1, and COX-2, compared with the levels of boys with CSF<\/p>\n<p>CONCLUSIONS:<\/p>\n<p>The intensity and consequences of pain were influenced by differential expression of miR-558, miR-146a, miR-150, miR-124, and miR-143, which was directly, associated with higher expression of immune inflammatory related genes TNF\u03b1, IL-6, and COX-2 in adolescences with CFS. Further studies of larger patient cohorts will help clarify the role of miRNAs in the pathogenesis of CFS.<\/p>\n<p><a href=\"http:\/\/sci-hub.tw\/https:\/\/doi.org\/10.1111\/papr.12817\" target=\"_blank\" rel=\"noopener noreferrer\">Read full paper<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>MicroRNAs as biomarkers of pain intensity in patients with chronic fatigue syndrome, by Hadeel A Al\u2010Rawaf, Ahmad H Alghadir, Sami A Gabr in Pain Pract. 2019 Jul 8. doi: 10.1111\/papr.12817.
