William Reeves

William C. Reeves, MD, MS (27 March 1943 - 3 Aug 2012) was an epidemiologist and former CFS Research Chief of the Centers for Disease Control & Prevention from 1992 to 2010. He was criticized for promoting psychological causal factors for ME/CFS, as well as for his department misspending funds appropriated for ME/CFS.

In 2010, he was removed from the CFS program and reassigned as Senior Advisor for Mental Health Surveillance in the Public Health Surveillance Program Office within the CDC. He died at his home in Atlanta on Aug. 3, 2012. He was 69.

Wichita Clinical Study
From December 2002 to July 2003 in Wichita, Kansas, USA, a 2-day in-hospital clinical assessment study was conducted by Reeves and his CDC department. It was named the Wichita Clinical Study. The complete data set is available on the CDC Wichita Clinical Study Data Access website. The study enrolled 227 people and classified them into five study groups, one with CFS patients as defined by the 1994 CDC Fukuda criteria case definition, one non-fatigued control group and three other groups reporting ongoing fatigue. The main objective of the study was to characterize the physiologic status of subjects with CFS, and to apply the 1994 CFS criteria to standardized reproducible criteria.

The conclusion of the Wichita Clinical Study published in 2005 stated: "The empirical definition includes all aspects of CFS specified in the 1994 case definition and identifies persons with CFS in a precise manner that can be readily reproduced by both investigators and clinicians."

In 2006, Reeves spoke at The National Press Club as part of a Chronic Fatigue Syndrome Awareness Campaign. Using results from the Wichita Clinical Study, he stated: "When we completed the medical workups of people in Wichita to confirm that they had CFS, we found that only half of those with the illness had consulted a physician for the illness. We found that only 16 percent had been diagnosed and treated for CFS...We found that a quarter of the people with CFS are either unemployed or receiving disability...We’ve documented, as have others, that the level of functional impairment in people who suffer from CFS is comparable to multiple sclerosis, AIDS, end-stage renal failure, [or] chronic obstructive pulmonary disease. The disability is equivalent to that of some well-known, very severe medical conditions.”

Case Definition
In 2005, the CDC published a paper outlining the Wichita Clinical Study which stated that the 1994 CDC case definition of CFS (called the empirical definition or the Fukuda criteria) was an accurate case definition. The study has garnered much criticism for not being specific enough to exclude patients which other illnesses. In particular, there is no mention of post-exertional malaise, instead they use the symptom "post-exertional fatigue." Since the study was led by Reeves, the case definition is sometimes referred to as the Reeves criteria although it has no distinction from the 1994 CDC case definition of CFS.

Prospective cohort study following patients from the time of acute infection with Epstein-Barr virus (glandular fever), Coxiella burnetii (Q fever), or Ross River virus (epidemic polyarthritis). The region surrounding the township of Dubbo in rural Australia, encompassing a 200 km geographical radius and 104,400 residents. 253 patients enrolled and followed at regular intervals over 12 months by self report, structured interview, and clinical assessment. Detailed medical, psychiatric, and laboratory evaluations at six months to apply diagnostic criteria for chronic fatigue syndrome. Premorbid and intercurrent illness characteristics recorded to define risk factors for chronic fatigue syndrome. Self reported illness phenotypes compared between infective groups. Prolonged illness characterised by disabling fatigue, musculoskeletal pain, neurocognitive difficulties, and mood disturbance was evident in 29 (12%) of 253 participants at six months, of whom 28 (11%) met the diagnostic criteria for chronic fatigue syndrome. This post-infective fatigue syndrome phenotype was stereotyped and occurred at a similar incidence after each infection. The syndrome was predicted largely by the severity of the acute illness rather than by demographic, psychological, or microbiological factors. A relatively uniform post-infective fatigue syndrome persists in a significant minority of patients for six months or more after clinical infection with several different viral and non-viral micro-organisms. Post-infective fatigue syndrome is a valid illness model for investigating one pathophysiological pathway to chronic fatigue syndrome.'"

In CFS patients with significant mental fatigue, sustained attention performance was impaired only in the final stages of the test, indicating greater cognitive fatigability in these patients.'"
