Ecotoxicological studies of surface and groundwater in the adjacent territories of the Shuakhevi HPP (Adjara AR)

Abstract

In the pathogenesis of autoimmune diseases, including immune thrombocytopenia (ITP), maintenance of inflammation and the loss of immune tolerance is essential. Transforming growth factor-beta (TGF-β) is a regulatory cytokine with pleiotropic function. TGF-β inhibits differentiation of T helper (Th1, Th2) cells and promotes the development of peripheral Tregs. The aim of our study was to explore the plasma levels of TGF-β and to perform its correlative analyses with peripheral blood biomarkers of systemic inflammation (NLR, PLR, PMR, SII, dNLR) in patients with ITP who did not respond to the first line treatment and had splenectomy as a second line therapy. The concentrations of TGF-β in plasma was quantified using ELISA kits by eBioscience. Statistical analyses was performed using Graph Pad Prism - Mann Whitney U test; for the correlation analyses we used spearman rank correlation by SPSS program. Our study revealed that the level of TGF-β in patients with refractory ITP is significantly diminished compared to the healthy subjects or patients undergoing splenectomy for other reasons than autoimmune or malignant hematological pathologies. There was no correlation observed between the plasma concentrations of TGF-β and the peripheral blood biomarkers of systemic inflammation.
