However, while even minor renal dysfunction is an independent predictor of adverse cardiovascular prognosis, PEW becomes clinically manifest at an advanced stage, early before or during the dialytic stage. Mechanisms causing loss of muscle protein and fat are complex and not always associated with anorexia, but are linked to several abnormalities that stimulate protein degradation and\/or decrease protein synthesis. In addition, data from experimental CKD indicate that uremia specifically blunts the regenerative potential in skeletal muscle, by acting on muscle stem cells. In this discussion recent findings regarding the mechanisms responsible for malnutrition and the increase in cardiovascular risk in CKD patients are discussed. During the course of CKD, the loss of kidney excretory and metabolic functions proceed together with the activation of pathways of endothelial damage, inflammation, acidosis, alterations in insulin signaling and anorexia which are likely to orchestrate net protein catabolism and the PEW syndrome.<\/jats:p>","DOI":"10.3390\/ijerph8051631","type":"journal-article","created":{"date-parts":[[2011,5,19]],"date-time":"2011-05-19T11:15:27Z","timestamp":1305803727000},"page":"1631-1654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":101,"title":["Protein-Energy Wasting and Mortality in Chronic Kidney Disease"],"prefix":"10.3390","volume":"8","author":[{"given":"Alice","family":"Bonanni","sequence":"first","affiliation":[{"name":"Division of Nephrology, Dialysis and Transplantation, Department of Internal Medicine, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Viale Benedetto XV 6, Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irene","family":"Mannucci","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Dialysis and Transplantation, Department of Internal Medicine, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Viale Benedetto XV 6, Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Verzola","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Dialysis and Transplantation, Department of Internal Medicine, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Viale Benedetto XV 6, Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonella","family":"Sofia","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Dialysis and Transplantation, Department of Internal Medicine, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Viale Benedetto XV 6, Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Saffioti","sequence":"additional","affiliation":[{"name":"Division of Nephrology, Dialysis and Transplantation, Department of Internal Medicine, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Viale Benedetto XV 6, Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ezio","family":"Gianetta","sequence":"additional","affiliation":[{"name":"Department of Surgery, Azienda Ospedale Universit\u00e0 San Martino, Genoa University, Largo R.
