Abstract
Over the past few years, medical care has dramatically improved knowledge of the pathogenic mechanisms of diseases, leading to more effective therapies as well as improved technologies, yielded to enhance survival for diseases that, just a few decades ago, would have been considered lethal. Unfortunately, not all diseases can be completely defeated. In many circumstances, therapies may delay the progression of the disease, leading to improved survival but bringing new issues to light. Of particular interest are nutritional and metabolic alterations due to both prolonged clinical course of disease and long-term therapies. Anorexia–cachexia syndrome often complicates the course of chronic illnesses. Anorexia (i.e., loss of appetite) and cachexia (i.e., loss of weight due to lean body mass and fat-mass wasting) are both associated with a number of diseases. The aim of this article is to highlight the clinical impact of the anorexia–cachexia syndrome and to review current and future etiologic therapeutic approaches.
