David Bell

David S. Bell, MD, is a retired American doctor who had a practice in General Medicine and Pediatrics. He was at the center of the 1985 Lyndonville outbreak of the disease in upper New York state in the United States. Dr. Bell serves on the Scientific Advisory Board of the Open Medicine Foundation.

He is one of the authors of the 2011 case definition, International Consensus Criteria.

Notable studies

 * 2012, Understanding long-term outcomes of chronic fatigue syndrome. Abstract: In a follow-up study "of the 25 participants diagnosed with CFS 25 years ago, 5 self-reported that they maintained a diagnosis of CFS, while 20 reported no longer having a CFS diagnosis...Those who remitted from CFS showed significantly more impairment on 21 out of 23 outcomes compared with controls,...suggest[ing] that over time many individuals will not maintain a CFS diagnosis but will not return to their premorbid level of functioning."
 * 2009, Severe versus Moderate criteria for the new pediatric case definition for ME/CFS. The study analyzed the Canadian Consensus Criteria when applied to pediatric patients and concluded: "Findings indicate that the Pediatric Case Definition for ME/CFS can distinguish between those with this illness and controls, and between those with Severe versus Moderate manifestations of the illness."
 * 2003, Predictive immunophenotypes: Disease-related profile in chronic fatigue syndrome
 * 2000, The roles of orthostatic hypotension, orthostatic tachycardia, and subnormal erythrocyte volume in the pathogenesis of the chronic fatigue syndrome. Method: "Fifteen patients were randomly selected from a large population of patients with chronic fatigue syndrome, studied, and observed for several years (by DSB). Blood pressure (BP) and heart rate (HR) measured with Dinamap every minute for 30 minutes supine and 60 minutes standing were compared with these findings in 15 healthy age- and gender-matched control subjects and later during lower body compression with military antishock trousers (MAST). Plasma catecholamines and circulating erythrocyte and plasma volumes were also measured by isotopic dilution methods." Results: "Abnormal findings in the patients included excessive orthostatic reductions in systolic (P < 0.001) and diastolic BP (P < 0.001) and excessive orthostatic tachycardia (P < 0.01), together with presyncopal symptoms in 11 of the 15 patients and in none of the control subjects after standing for 60 min. Lower body compression with the MAST restored all orthostatic measurements to normal and overcame presyncopal symptoms within 10 min. Circulating erythrocyte but not plasma volumes were subnormal in the 12 women (P < 0.01) and plasma norepinephrine concentration rose excessively after standing for 10 min."

Open Letter to The Lancet
Two 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. Bell, along with 41 colleagues in the ME/CFS field, signed the second letter.
