[Malnutrition in patients on chronic hemodialysis: prevalence, pathogenesis, and treatment]. / La malnutrizione nel paziente in emodialisi cronica: prevalenza, patogenesi, terapia.

ABSTRACT

Malnutrition is common in patients on hemodialysis and is a strong predicor of morbidity and mortality. Much progress has been made in recent years in identifying the causes and pathogenesis of malnutrition in hemodialysis patients as well as in recognizing the link between malnutrition and morbidity and mortality. Nevertheless, there is no consensus concerning its management. Conventional interventions such as nutritional counseling, oral nutritional supplements and intradialytic parenteral nutrition and novel preventive and therapeutic strategies such as appetite stimulants, growth hormone, androgenic anabolic steroids, and antiinflammatory drugs have been tested with contradictory and inconclusive results. Malnutrition still remains an important challenge for the nephrologist in the third millennium.
