Interleukin (IL)-6 has become a major target for clinical intervention in various autoimmune conditions. Here, drugs including the humanized anti-IL-6 receptor (IL-6R) antibody tocilizumab emphasize the clinical importance of IL-6 in driving disease and poor patient outcomes. During the course of this review, we will outline the biology surrounding IL-6 and discuss the impact of IL-6 in renal disease and the clinical complications associated with renal replacement therapies and transplantation. We will also consider the merit of IL-6 measurement as a prognostic indicator and provide a clinical perspective on IL-6-blocking therapies in renal disease.
Keywords: cytokines; interleukin-6; renal disease; therapy.
