Features of the local cytokine profile of patients with bullous keratopathy by using personalized therapy with cellular technologies

Abstract

Background. Today we have active development of ophthalmic surgery, but the role of cytokines in the pathogenesis of bullous keratopathy of the cornea remains insufficiently studied at present.The aim. To study the dynamics of the local cytokine profile in bullous keratopathy by using personalized treatment with suspension of autologous blood mononuclears.Material and methods. Two groups of patients with bullous keratopathy were formed: the main group (30 people, 30 eyes), who received an intrastromal injection of a suspension of autologous blood mononuclears and comparison (28 people, 28 eyes), who received a course of pharmacotherapy. The level of interleukins (IL) – IL-10, IL-4, IL-6, IL-1ß, transforming growth factor beta-2 (TGF-β2), tumor necrosis factor alpha (TNF-α) was determined in the lacrimal fluid of the patient’s eye by enzyme immunoassay.Results. All patients before treatment showed an increase of IL-1ß in the lacrimal fluid by 3.3 times, IL-6 – by 4.2 times, TNF-α – by 2.0 times (p < 0.05); an increase in the level of IL-4, IL-10 and TGF-β2 by 1.1 times (p > ˂ 0.05). In the main group, after treatment, there was a decrease in IL-1ß by 2.0 times, IL-6 – by 2.1 times and TNF-α – by 1.8 times, and an increase in IL-10 by 1.5 times, IL-4 – by 1.9 times, TGF-β2 – by 1.4 times (p < 0.05), persisting for 12 months. There was a short-term decrease of IL-1ß by 1.7 times, IL-6 and TNF-α – by 1.2 times and an increase of IL-10, IL-4, TGF-β2 by 1.2 times (p >< 0.05) in the comparison group which then reached the initial values. Conclusion. There is an imbalance in the system of pro- and anti-inflammatory cytokines in bullous keratopathy in the lacrimal fluid. Injection of autologous mononuclear cells in the stroma of the cornea reduces the severity of the imbalance of the local cytokine system compared to the course of pharmacotherapy.
