Vitamin D and pro-inflammatory cytokine IFN-γ and the anti-inflammatory cytokines IL-4 and IL-10 in Peritoneal Dialysis Patients

Abstract
Several clinical trials in patients with chronic disease have found that active vitamin D usage lowers pro-inflammatory cytokines. The aim of this study was evaluate whether supplementation of cholecalciferol in peritoneal dialysis patients with vitamin D deficiency would lead any chance in the pro-inflammatory cytokine IFN-γ and the anti-inflammatory cytokines IL-4 and IL-10, and pentraxin 3 and peripheral blood mononuclear cell subpopulations (CD3, CD4, CD8, CD45)and CD4/CD8 ratio. We analyzed fasting blood samples from 31 continuous peritoneal dialysis patients (14 males, 16 females, mean age 48,6±14,8 yrs) for serum 25-hydroxyvitamin D [25(OH)D)] and specific plasma cytokine concentrations (interferon-gamma [IFN-γ], interleukin [IL]-4, and IL-10), pentraxine 3, CD3, CD4, CD8 and CD45 before and after cholecalciferol replacement. Before and after cholecalciferol replacement mean 25 (OH) level was 6,1±2,1 ng/dL and 39,7±10,9 ng/dL respectively (p
