Содержание иммуноглобулинов A, M, G в слезной жидкости у больных первичной открытоугольной глаукомой

Abstract

PURPOSE: To define changes of immunoglobulins A, M, G in the tear fluid of patients with primary open-angle glaucoma (POAG). METHODS: We investigated the content of serum immunoglobulins and secretory immunoglobulin A in the tear fluid of patients with POAG and people with risk of its development. RESULTS: The level of IgG, which is the main immunoglobulin of the secondary immune response, was slightly elevated. Investigation of IgA concentration in the serum of patients with POAG showed an increase. Serum IgA concentration in the risk group almost did not differ from the control group. CONCLUSION: The study of immunoglobulin G, M and A in the serum of patients with POAG showed a slight increase Conflicts of Interest and Source of Funding: none declared. in their concentrations, indicating the activation of humoral mechanisms of immunopathogenesis in patients with POAG. Concentrations of secretory immunoglobulin A (sIgA) in the tear fluid was increased both in patients with POAG and in the risk group. It gives reason to consider the local humoral mechanisms an important link in the development of immune inflammation in primary open-angle glaucoma. Selective accumulation of sIgA in the tear fluid indicates an increase in the protective function of the mucous in response to any antigen, toxin, autoantigen, and the aim to limit the development of the pathological process
