Exploring the Biological Basis of Chronic Fatigue Syndrome

DxTerity Diagnostics380 enrolled

Overview

To collect blood and urine samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and SEID (Systemic Exertion Intolerance Syndrome) and controls for genomic, viral and metabolomic testing.

To analyze gene expression (genomic) and viral analysis data from patients diagnosed with ME/CFS, the study will collect blood samples (finger stick) and information from up to 500 subjects for analysis. In addition, urine will be collected for all subjects to evaluate the study subject's metabolomics. All participants will complete a single Study Collection event consisting of at least one MCD (2nd sample is optional) and one urine collection from home: 10% of each group (ME/CFS and Control) will complete a second Study Collection event approximately 1 to 2 weeks after the initial Study Collection. The second collection is to compare data between two collections from the same participants to observe any time-related changes in the results.

Outcomes

Primary Outcomes

Collect blood samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for genomic testing.

To enable research focused on discriminating differentiated symptoms of various sources of CFS from other autoimmune and viral pathogenesis of disease which could prove valuable in researching for inflammation and immunity related therapeutics.

Time frame: 3 months

Collect blood samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for viral testing.

Time frame: 3 months

Collect urine samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and Systemic Exertion Intolerance Syndrome (SEID), and controls for metabolomic testing.
