Chia J, Chia A, Voeller M, Lee T, Chang R. Acute enterovirus infection followed by myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and viral persistence. J Clin Pathol. 2010 Feb;63(2):165-8. PMID: 19828908

Three representative patients with different manifestations of acute enterovirus infections progressed to have chronic symptoms of ME/CFS. Persistent viral infection was demonstrated in the antrum years later. Chronic enterovirus infection in an immunocompetent host may be an example of a stalemate between attenuated, intracellular viruses and an ineffective immune response.

Chia JK, Chia AY. Chronic fatigue syndrome is associated with chronic enterovirus infection of the stomach. J Clin Pathol. 2008 Jan;61(1):43-8. PMID: 17872383

Enterovirus VP1, RNA and non-cytopathic viruses were detected in the stomach biopsy specimens of CFS patients with chronic abdominal complaints.

Chia JK. The role of enterovirus in chronic fatigue syndrome. J Clin Pathol. 2005 Nov;58(11):1126-32. PMID: 16254097

Enteroviruses may play a role in CFS.

Nairn C, Galbraith DN, Clements GB. Comparison of coxsackie B neutralisation and enteroviral PCR in chronic fatigue patients. J Med Virol. 1995 Aug;46(4):310-3. PMID: 7595406

More CFS patients than controls had evidence of enterovirus on a PCR assay.

Galbraith DN, Nairn C, Clements GB. Phylogenetic analysis of short enteroviral sequences from patients with chronic fatigue syndrome. J Gen Virol. 1995 Jul;76 ( Pt 7):1701-7. PMID: 9049375

The research results suggest there is persistence of enterovirus infection in some CFS patients and indicate the presence of distinct novel enterovirus sequences.

Clements GB, McGarry F, Nairn C, Galbraith DN. Detection of enterovirus-specific RNA in serum: the relationship to chronic fatigue. J Med Virol. 1995 Feb;45(2):156-61. PMID: 7775934

Enteroviral specific sequences were detected in 36 of 88 serum samples from chronic fatigue patients and 3 of 126 healthy individuals.

Bowles NE, Bayston TA, Zhang HY, Doyle D, Lane RJ, Cunningham L, Archard LC. Persistence of enterovirus RNA in muscle biopsy samples suggests that some cases of chronic fatigue syndrome result from a previous, inflammatory viral myopathy. J Med. 1993;24(2-3):145-60. PMID: 8409778

CFS may be a sequela of a previous inflammatory viral myopathy.

An increase in the number and size of muscle mitochondria was found in 70% of postviral fatigue cases cases, suggesting an abnormality in metabolic function. Evidence of hypothalamic dysfunction was present, particularly involving 5-hydroxytryptamine metabolism.

Gow JW, Behan WM. Amplification and identification of enteroviral sequences in the postviral fatigue syndrome. Br Med Bull. 1991 Oct;47(4):872-85. PMID: 1665380

A highly significant number of muscle biopsies from CFS patients were positive for enteroviral sequences.

Gow JW, Behan WM, Clements GB, Woodall C, Riding M, Behan PO. Enteroviral RNA sequences detected by polymerase chain reaction in muscle of patients with postviral fatigue syndrome. BMJ. 1991 Mar 23;302(6778):692-6. PMID: 1850635

Persistent enteroviral infection of muscle may occur in some patients with postviral fatigue syndrome.

Cunningham L, Bowles NE, Lane RJ, Dubowitz V, Archard LC. Persistence of enteroviral RNA in chronic fatigue syndrome is associated with the abnormal production of equal amounts of positive and negative strands of enteroviral RNA. J Gen Virol. 1990 Jun;71 ( Pt 6):1399-402. PMID: 2161907

This study suggests that enterovirus persistence in muscle is due to a defect in control of viral RNA synthesis.
