Abstract

Objective: To assess the effects of depression and anxiety on serum cytokine levels in patients with chronic hepatitis B (CHB) infection. Methods: In this cross-sectional study, 60 healthy control individuals and 60 patients with CHB participated after filling out standard questionnaires. We examined their serum interleukin (IL)–6, IL-8, tumor necrosis factor (TNF)–α, and TGF-β levels using enzyme-linked immunosorbent assay (ELISA) techniques. Results: In patients with CHB compared with healthy controls, serum levels of IL-8 were significantly increased, whereas IL-6 and TGF-β levels were significantly decreased. Serum levels of TGF-β were significantly decreased in the patients with CHB who had mild depression, compared with patients with CHB without depression and with moderate and severe depression. Conclusions: Downregulation of IL-8 and TGF-β, respectively, is a corresponding mechanism for induction of chronic inflammation in patients with CHB. Depression also seems to induce inflammation via downregulation of TGF-β in these patients. © American Society for Clinical Pathology 2017. All rights reserved.
