Comment on: Chronic fatigue syndrome: a joint paediatric-psychiatric approach. [Arch Dis Child. 1992]
SIR,-While agreeing that physical, psychological, and social factors must all be taken into account in the management of this complex and controversial syndrome I would disagree with Dr Margaret Vereker’s statement that no organic pathology can be detected to account for any of the symptoms. This conclusion has been made without reference to a number of research papers describing persisting viral infection, neuromuscular abnormalities in both structure and function, and immune system dysfunction.
Gow et al using polymerase chain reaction techniques, have been able to demonstrate the presence of enteroviral genome in muscle biopsies from a significant number of patients (53%) compared with controls (15%). None of the healthy control group in this study had evidence of viral particles in their muscle, this was only found in those with colonic or breast malignancies. Precisely what cytopathological effect this intracellular virus is having within muscle remains open to debate. However, Behan et al have published electron microscopic evidence of structural damage to the muscle mitochondria along with type II fibre atrophy; this is a finding which is not normally considered to be consistent with simple disuse.
