Association of autoimmunity and cicatricial pemphigoid: is there an immunogenetic basis?

A group of 34 patients with cicatricial pemphigoid was investigated for the presence of autoimmune disorders. Thirty-two percent of patients had autoimmune disease compared with 7% in the control population, a highly significant difference (p less than 0.002). Circulating autoantibodies were also significantly more common in patients (p less than 0.05). Twenty-four patients with cicatricial pemphigoid were typed for HLA. A statistically significant increase in the frequency of DR4 and DQw3 antigens was observed in these patients. These findings suggest a possible genetic basis for the autoimmune association and predisposition for development of cicatricial pemphigoid.
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
