“…31 Deviations from the T-cell cytokine balance [32][33][34] and low plasma vitamin D concentrations [35][36][37] are related to cardiovascular events 34,37 as well as altered immunocompetence during infections 32,35 and vaccinations. 33,36 Serum parathyroid hormone (PTH) levels are dependent on serum vitamin D concentrations, 38 and T cells are implicated in the mechanism of the PTH action in the bone. 39 We aimed to check a frequency distribution of polymorphic variants of the genes encoding cytokines/ILs related to Th1 and Th2 cells (IL18 rs360719, IL13 rs20541, IL4R rs1805015, IL12A rs568408, IL12B rs3212227, IL28B rs8099917, IL28B rs12979860, and MCP1 rs1024611) as well as polymorphisms of the vitamin D pathway genes (the vitamin D-binding protein gene, also referred to as the group-specific component gene: GC rs2298849, GC rs1155563, GC rs7041; vitamin D receptor gene: VDR rs2228570, VDR rs1544410; and retinoid X receptor alpha gene: RXRA rs10 776 909, RXRA rs10881578, and RXRA rs749759) in relation to survival probability of patients with ESRD requiring renal replacement therapy (RRT).…”
