Articles were grouped into four categories to facilitate a rapid overview. First regarding the definition of acute renal failure ARF the RIFLE criteria risk injury failure loss ESKD end-stage kidney disease for diagnosis of ARF were defined by the Acute Dialysis Quality Initiative workgroup and applied in clinical practice by some authors. The second category is acid-base disorders in ARF the Stewart-Figge quantitative approach to acidosis in critically ill patients has been utilized by two groups of researchers with similar results but different conclusions. In the third category - blood markers during ARF - cystatin C as an early marker of ARF and procalcitonin as a sepsis marker during continuous venovenous haemofiltration were examined. Finally in the extracorporeal treatment of ARF the ability of two types of high cutoff haemofilters to influence blood levels of middle- and high-molecular-weight toxins showed promise. Introduction During 2004 Critical Care accepted and published original research articles focused on nephrology and renal replacement therapy RRT . These studies included reports on various aspects of acute renal failure ARF acid-base approach and treatment and RRT insights into
