Area of Science:

  • Nephrology
  • Clinical Nutrition

Background:

  • Maintenance hemodialysis patients exhibit a high risk of malnutrition, linked to reduced life expectancy and increased cardiovascular and infectious complications.
  • Factors contributing to malnutrition include reduced protein-energy intake, anorexia, altered taste, intercurrent illnesses, and hospitalizations.

Purpose of the Study:

  • To review the multifactorial causes of malnutrition in hemodialysis patients.
  • To discuss the association between malnutrition and adverse outcomes in this population.
  • To highlight monitoring and therapeutic strategies for managing malnutrition.

Main Methods:

  • Cross-sectional and longitudinal studies were reviewed.
  • Factors contributing to malnutrition were analyzed.
  • Therapeutic interventions and emerging strategies were discussed.

Main Results:

  • Malnutrition is prevalent in hemodialysis patients and associated with poorer prognosis.
  • Causes are multifactorial, including dietary issues, catabolism, inflammation, and nutrient losses during dialysis.
  • Effective management requires careful monitoring and interventions like nutritional support and optimized dialysis.

Conclusions:

  • Malnutrition is a serious complication in hemodialysis patients, necessitating proactive monitoring and management.
  • Optimizing dialysis, addressing catabolism, and providing nutritional support are key to improving outcomes.
  • Emerging therapies offer new avenues for combating malnutrition in this vulnerable group.
