Continuation of the Rituximab trial in Norway. The modest increase in serum BAFF levels at baseline may indicate an activated B-lymphocyte system in a subgroup of ME/CFS patients.
CFS individuals analyzed in this study show no differences in B-cell compartment, skewed NK cells and poorly responsive T cells.
The observed immunological defaults do not provide any causative link to the illness, but could explain some of the symptoms and in particular the poor control of viral infections reported in these individuals. Some of these biomarkers may be useful for the characterization of CFS. (But you have to distinguiesh between ME, CFS ,or both).
Positive autoimmune reactions against serotonin were significantly higher in CFIDS patients than controls.
Patients with serotonin( 5-HT ) autoimmune activity displayed higher TNFα, IL-1 and neopterin and increased IgA responses against LPS of commensal bacteria than those without 5-HT autoimmune activity. Anti-5-HT antibody positivity was significantly associated with increased scores on hyperalgesia, fatigue, neurocognitive and autonomic symptoms, sadness and a flu-like malaise.
