Clinical Trial Summary

This study investigates whether there is an immune response directed against gut microbes or food and parts of the body in severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients.


Description:

Severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients will be identified by Epsom and St Helier CFS Service and the Clinical Research Network Eastern. Information sheets will be posted by health professionals to eligible patients. Interested patients are asked to arrange a telephone call with the research team to receive more information about the study. Volunteers still interested after the 72 hour consideration period arrange a home visit to be taken through the consenting process.

Household controls will be recruited through patients participating in the study. Patients invited will be provided with information about household controls. The patient identifies and informs potential household controls of the study using information sheets provided by their health professional. Household controls willing to participate in the study will be taken through an eligibility questionnaire with GCP trained researchers.

Six stool and blood samples will be collected over the three year study period. Stool and blood samples need to be collected within 24 hours of each other, during home visits. 48 hour food diaries will be completed prior to each stool sample collection.

The study is based at the Quadram Institute and the University of East Anglia (UEA). The research is funded by the UEA and Invest in ME Research UK.

Outcome

Type Measure Description Time frame Safety issue
Primary Measurement of antibody levels Measurement of serum antibodies that are reactive with intestinal microbes or foods. Antibody levels will reflect the presence of an immune response directed against gut microbes in severe ME/CFS patients. 3 years
Primary Measurement of cellular immune responses Measurement of memory T and memory B cells (from peripheral blood mononuclear cells in the blood) specific to gut microbes (from stool sample). The presence of memory T and B cells will indicate a systemic (whole body) immune response directed against gut microbes in severe ME/CFS patients. 3 years
Primary Expression of microbial and viral DNA/RNA To identify the bacterial, fungal and virus populations in stool samples. 3 years
Secondary Measurement of autoimmunity Measurement of serum antibodies and immune cells that are reactive with human cells, such as cells of the central nervous system. The presence of an immune response against human cells and human cell proteins is indicative of the presence of autoimmunity. 3 years
