| description | In accordance with Clinical Guidelines of the Russian Society of Dermatovenerologists and Cosmetologists, atopic dermatitis is a chronic allergic genetically determined dermatosis of a multifactorial nature. There are, however, some aspects that challenge the allergic nature of dermatosis. For example, according to literature data, not all the patients have increased synthesis of immunoglobulin E, some of them are torpid to antihistamine treatment, and, when examining the skin of some patients with atopic dermatitis, an absolute polymorphism of rashes is revealed, thus being not typical to the reagin-type allergic reactions. According to modern data, autoimmune theory is assumed for the mechanisms of atopic dermatitis. However, objective proofs of this theory have not been presented, thus drawing our attention to the studies of this issue. The aim of this study was to identify autoimmune pathogenetic mechanisms of atopic dermatitis. The study included 40 adolescents and 40 adult patients with limited and extended forms of atopic dermatitis. The patients were evaluated during the period of exacerbation and remission of the disease. Blood and skin exudates samples were taken from all the patients. The control group consisted of 30 practically healthy volunteers in whom skin exudate was obtained by the “skin window” technique as proposed by Klimov V.V. et al. “A method for assessing minimal inflammatory activity of skin in atopic dermatitis in remission”. Concentrations of IgG autoantibodies to collagen types I and III were determined in blood serum and skin exudate samples applying ELISA techniques with ready-made panels AEA571Hu ELISA Kit for Anti-Collagen Type I Antibody (USA), AEA176Hu ELISA Kit for Anti-Collagen Type III Antibody (USA), according to the manufacturer’s protocols. For the first time, the contents of autoantibodies to skin collagen types I and III in the patients with atopic dermatitis we studied in parallel, i.e., at systemic level and in affected skin. If compared to the group of healthy volunteers, the concentration of autoantibodies to collagen types I and III was found to be increased in all the patients with atopic dermatitis, both during exacerbation and in remission of the disease. The maximal values of autoantibodies to collagen types I and III were recorded in blood serum upon development of clinical symptoms of dermatosis, along with low contents of these antibodies detectable in their skin exudates. Permanently high concentrations of autoantibodies to collagen types I and III in blood serum at exacerbation and remission of atopic dermatitis, and their low level in their skin exudate suggest emergence of circulating and precipitating immune complexes, thus allowing us to consider atopic dermatitis as an autoimmune process. |
