BioSEND banks biospecimens related to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) available for analysis by approved Investigators.

ME/CFS

BioSEND banks a wide range of biospecimen types from a ME/CFS-related study. Samples were collected through a study sponsored by the Chronic Fatigue Initiative (CFI). CFI’s goal was to disseminate its research findings to better equip the broader research community to work on mechanisms of ME/CFS and associated diagnostics, treatment, and prevention. The CFI study has resulted in a cohort of both case and control subjects with clinical data and the below specimen types.

Study Details

Chronic Fatigue Initiative (CFI) Study

The CFI study was a multicenter cross-sectional observational study, with the objective of establishing a well-characterized cohort of participants diagnosed with ME/CFS and controls with both clinical data and biologic specimens. The CFI was created and funded by the Hutchins Family Foundation and the clinical data and biospecimens were transferred to the National Institute of Neurological Disorders and Stroke. Investigators who request access to the CFI resource will be required to comply with the BioSEND Biospecimens User Agreement and/or the Data Use Agreement and to adhere to the Publication Policy.

Study Subjects

201 ME/CFS cases and 200 controls.

Available Data

Demographic and lifestyle data are currently available, in addition to questionnaire data to aid in characterizing ME/CFS. The questionnaires administered to the CFI study participants include the Pittsburgh Sleep Quality Index, Short Form Survey (SF-36), DePaul Symptom Questionnaire, Multidimensional Fatigue Inventory, Brief Pain Inventory, Beck Anxiety Inventory, and Depression Inventory. All data are de-identified to protect participant privacy.
