Polenakovic Preface The book Renal Failure – The Facts consists of some facts about diagnosis, etiopathogenis and treatment of acute and chronic renal failure. Acute, as well as chronic renal failure is great medical problems and their treatment is a burden for the budget of each government. Acute kidney injury (AKI), previously termed acute renal failure, is a frequent clinical condition in critically ill patients especially, in intensive care units (ICU). Its incidence varies from 1-7 % of all hospitalized patients to 30-50 % of patients in ICU. Irrespective of the progress being made in the understanding of the pathophysiology of AKI and its underlying processes and the advances in critical care medicine, mortality rate associated with AKI remains high especially in ICU patients at more than 50 %. In addition, a significant proportion of surviving patients (20 %) develops CKD and end-stage renal disease, requiring chronic renal replacement therapy. Long-term outcome is worse for patients after recovery from AKI, further impacting health care cost and quality of life. In developing countries, AKI is more common in young and pediatric patients, while in developed countries elderly patients are predominant. In critically ill patients the most common cause of AKI is sepsis, accounting for 50 % of all cases. Chronic kidney disease (CKD) is a long-term condition which can arise from the damage to the kidneys from a variety of diseases. Patients with CKD are frequently asymptomatic until the disease is advanced. In 2002 the K/DOQI Clinical Practice Guidelines provided a definition of CKD which is now widely used around the world. Generally, cross-sectional population studies in a number of countries suggests an overall prevalence of CKD 1-5 of >10%. CKD appears to be an independent and significant risk factor for progressive cardio vascular disease (CVD). CVD accounts for ≈ 50% of the death in patients with CKD. The purpose of the chapters is to present some important issues of diagnosis and causes of AKI, as well as caused by snakes and arthropods, after cardiac surgery, as well as some therapeutic achievements in AKI. Well presented are the psychological condition in patients on haemodialysis, as well as the treatment of diabetic uremics. X Preface The book is aimed at clinicians with a special interest in nephrology (including consultants and specialist trainees in nephrology), but it should also prove to be a valuable resource for any generalists who encounter a nephrological problems in their day-to-day practice.
