Ohanian D, Brown A, Sunnquist M, Furst J, Nicholson L, Klebek L, Jason LA. Identifying Key Symptoms Differentiating Myalgic Encephalomyelitis and Chronic Fatigue Syndrome from Multiple Sclerosis. Neurology (ECronicon). 2016;4(2):41-45. PMID: 28066845
The current study compared self-report symptom data of patients with ME or CFS with those with MS. The best discriminating symptoms were from the immune domain (i.e., flu-like symptoms and tender lymph nodes), and the trees correctly categorized MS from ME or CFS 81.2% of the time, with those with ME or CFS having more severe symptoms.
Johnston SC, Staines DR, Marshall-Gradisnik SM. Epidemiological characteristics of chronic fatigue syndrome/myalgic encephalomyelitis in Australian patients. Clin Epidemiol. 2016 May 17;8:97-107. PMID: 27279748
A cross-sectional survey on the medical history of patients enrolled in an Australian CFS/ME research database between April 2013 and April 2015. Participants were classified according to Fukuda criteria and International Consensus Criteria. Within those meeting CFS/ME criteria, the most common events prior to illness included cold or flu, gastrointestinal illness, and periods of undue stress. Of the 60 symptoms surveyed, fatigue, cognitive, and short-term memory symptoms, headaches, muscle and joint pain, unrefreshed sleep, sensory disturbances, muscle weakness, and intolerance to extremes of temperature were the most commonly occurring symptoms (reported by more than two-thirds of patients).
Chen Y, Liu W, Zhang L, Yan M, Zeng Y. Hybrid facial image feature extraction and recognition for non-invasive chronic fatigue syndrome diagnosis. Comput Biol Med. 2015 Sep;64:30-9. PMID: 26117650
Individuals with CFS were found to have specific identifiable facial features, including vertical striped wrinkles on the forehead, puffiness of the lower eyelid, the skin colour of the cheeks, nose and lips, and the shape of the mouth corner.
Ravindran M, Adewuyi O, Zheng Y, Rayhan RU, Le U, Timbol C, Merck S, Esteitie R, Read C, Cooney M, Baraniuk J. Dyspnea in Chronic Fatigue Syndrome (CFS): comparison of two prospective cross-sectional studies. Glob J Health Sci. 2012 Dec 12;5(2):94-110. PMID: 23445698
This study showed that a much higher percentage of CFS patients than healthy controls significant dyspnea (shortness of breath).
Maloney EM, Boneva RS, Lin JM, Reeves WC. Chronic fatigue syndrome is associated with metabolic syndrome: results from a case-control study in Georgia. Metabolism. 2010 Sep;59(9):1351-7. PMID: 20102774
CFS was associated with metabolic syndrome, which further exacerbated fatigue.
Meeus M, Nijs J, Huybrechts S, Truijen S. Evidence for generalized hyperalgesia in chronic fatigue syndrome: a case control study. Clin Rheumatol. 2010 Apr;29(4):393-8. PMID: 20077123
CFS patients exhibited more generalized hyperalgesia than controls.
Fisher MM, Rose M. Anaesthesia for patients with idiopathic environmental intolerance and chronic fatigue syndrome. Br J Anaesth. 2008 Oct;101(4):486-91. PMID: 18782886
Anaesthesia is likely to be associated with adverse effects in CFS patients but the effects are not likely to be severe.
Wyller VB, Godang K, Mørkrid L, Saul JP, Thaulow E, Walløe L. Abnormal thermoregulatory responses in adolescents with chronic fatigue syndrome: relation to clinical symptoms. Pediatrics. 2007 Jul;120(1):e129-37. PMID: 17606539
Adolescent patients with chronic fatigue syndrome have abnormal catecholaminergic-dependent thermoregulatory responses, suggesting sympathetic dysfunction and possibly.
Nijs J, Aerts A, De Meirleir K. Generalized joint hypermobility is more common in chronic fatigue syndrome than in healthy control subjects. J Manipulative Physiol Ther. 2006 Jan;29(1):32-9. PMID: 16396727
CFS patients were more likely than controls to have joint hypermobility.
van de Putte EM, Uiterwaal CS, Bots ML, Kuis W, Kimpen JL, Engelbert RH. Is chronic fatigue syndrome a connective tissue disorder? A cross-sectional study in adolescents. Pediatrics. 2005 Apr;115(4):e415-22. PMID: 15805343
Patients with CFS had lower blood pressure, stiffer arteries and more extensible skin, but did not have joint hypermobiity.
Shee CD. Phantom lymphadenopathy. An association with chronic fatigue syndrome. Postgrad Med J. 2003 Jan;79(927):59-60. PMID: 12566557
Phantom lymphadenopathy may be a symptom in some people with CFS.
Jason LA, Torres-Harding SR, Carrico AW, Taylor RR. Symptom occurrence in persons with chronic fatigue syndrome. Biol Psychol. 2002 Feb;59(1):15-27. PMID: 11790441
Headaches, lymph node pain, sore throat, joint pain, muscle pain, muscle weakness at multiple sites differentiate CFS patients from controls. The disease includes many cardiopulmonary, neurological, and other symptoms not included in the CDC case definition.
Barron DF, Cohen BA, Geraghty MT, Violand R, Rowe PC. Joint hypermobility is more common in children with chronic fatigue syndrome than in healthy controls. J Pediatr. 2002 Sep;141(3):421-5. PMID: 12219066
Joint hypermobility is more common in patients with CFS than in otherwise healthy children with common skin disorders.
