Inclusion Criteria: - severe ME/CFS patients: men or women aged 18 to 70 years with a clinical diagnosis of severe ME/CFS patients - household controls: men or women aged 18 to 70 years, no current or on-going medical conditions. Has to be either related/non-related, living in the same household or in close proximity to, or providing care to the severe ME/CFS patient they are paired with. Exclusion Criteria: - severe ME/CFS patients: the presence of significant anxiety or depression. Have received probiotics or antibiotics up to six weeks before joining the study. - Household controls: The presence of long term medical conditions, in particular, affecting the stomach or bowel. Previously diagnosed with autoimmune diseases, for example, systemic lupus erythematous or rheumatoid arthritis. Suffer from significant anxiety or depression. In recipient of immunomodulatory drugs, statins, beta blocker or steroids. Have received probiotics or antibiotics up to six weeks before joining the study. |

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 |
