Update on the Role of Polymethylmethacrylate Membrane Hemofilter in Acute and Chronic Renal Dysfunction.

Despite recent technical advances in dialysis care over the past decades, the mortality rate of critically ill patients with acute kidney injury (AKI) requiring dialysis and of chronic kidney disease (CKD) remains unacceptably high. Several preclinical studies have increased our knowledge of the principal mechanisms involved in the pathophysiology of AKI and CKD. Additionally, the development of efficient and specific compensatory sorbent systems in renal replacement therapy to remove unwanted compounds has created the possibility to treat renal diseases and their underlying pathological triggers. Recently, several biomedical blood purification materials have been developed to improve the removal of waste and inflammatory compounds, improve the quality of treatment, and reduce the duration of treatment. This chapter is focused on the principal mechanisms involved in AKI and CKD and the current state of the art for blood purification strategies to identify the most feasible solution to reduce immunological dysfunction and waste compound clearance. In this regard, the current literature underlines the high efficacy of polymethyl methacrylate membrane hemofilters to overcome the shortcomings in the efficiency of current methodologies in removing the excess of metabolic waste and inflammatory mediators from blood. The purpose of this chapter is therefore to enhance physicians' knowledge about PMMA.
