Researchers report an exaggerated immune response can trigger chronic fatigue syndrome. The study reveals levels of Il-10 were higher in those who developed lasting fatigue, suggesting the immune system may have been primed to over respond.
Some cases of chronic fatigue syndrome could be caused by Human Herpesvirus 6, a new study suggests.
Contrary to previous findings, new research finds no link between chronic fatigue syndrome and the viruses XMRV (xenotropic murine leukemia virus-related virus) and pMLV (polytropic murine leukemia virus). A study reveals that research that reported patients with chronic fatigue syndrome carried these two viruses was wrong and that there is still no evidence for an infectious cause behind chronic fatigue syndrome.
