Immuglobulin A (IgA) is an antibody that plays a crucial role in mucosal immunity.
It is the main immunoglobulin found in mucous secretions including the gastrointestinal tract.
Chronic fatigue syndrome[edit | edit source]
A study of 128 ME/CFS patients found significantly increased IgA response to lipopolysaccharides (LPS) from the cell walls of commensal bacteria. Increased IgA response was associated with increased serum IL-1, TNFα, neopterin and elastase. The study concluded that increased translocation of commensal bacteria may be responsible for the disease activity in some ME/CFS patients.[1]
Another study found elevated serum concentrations of both IgA and IgM to LPS of gram-negative bacteria. Serum IgA levels correlated with illness severity as measured by the FibroFatigue scale[2]
