Dr. John K. S. Chia is an infectious disease doctor with a medical practice in Torrance, California. Dr. Chia became heavily involved in research and clinical care of myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) patients after his son, Andrew Chia, became ill with CFS in 1997. He has published several papers[1] on infectious causes of ME and CFS, including evidence of involvement of enteroviruses such as coxsackie B and echovirus, other viruses such as parvovirus B19, as well as bacteria such as Chlamydia pneumoniae. In addition to his clinical work, he runs his own enterovirus research laboratory[2] and is on the board of directors of the Enterovirus Foundation.

Dr. Chia has performed clinical trials[3] in an attempt to find treatment for patients with ME and CFS. His treatment attempts have focused on the use of antiviral compounds such as amantadine, ribavirin, and lamivudine in addition to immune modulators such as interferon and the plant compound oxymatrine. Towards this end, he and his son, a pharmacist, have developed his own proprietary herbal preparation containing oxymatrine and other plant compounds, called Equilibrant.

International Consensus Criteria[edit | edit source]

Dr. Chia co-authored the 2011 case definition, International Consensus Criteria.[4]


Open Letter to The Lancet[edit | edit source]

Three open letters to the editor of The Lancet urged the editor to commission a fully independent review of the PACE trial, which the journal had published in 2011. In 2016, Dr. Chia, along with 41 colleagues in the ME/CFS field, signed the second letter. In 2018, Dr. Chia was joined with over 100 signatories.

Myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.

Antibody - Antibodies or immunoglobulin refers to any of a large number of specific proteins produced by B cells that act against an antigen in an immune response.

Chronic fatigue (CF) - Persistent and abnormal fatigue is a symptom, not an illness. It may be caused by depression, multiple sclerosis, fibromyalgia, chronic fatigue syndrome or many other illnesses. The term "chronic fatigue" should never be confused with the disease chronic fatigue syndrome.

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.
