Nutritional therapy for patients undergoing hemodialysis

Area of Science:

• Nephrology
• Nutritional Science
• Cardiovascular Medicine

Background:

• Protein energy malnutrition (PEM) is a known risk factor for morbidity and mortality in hemodialysis (HD) patients.
• Inflammation may link PEM to cardiovascular events in HD patients.
• The cardiovascular and mortality implications of over-nutrition in HD patients are not well understood.

Purpose of the Study:

• To investigate the role of over-nutrition as a risk factor for cardiovascular diseases and mortality in HD patients.
• To explore metabolic abnormalities and adiponectin levels in over-nourished HD patients.
• To determine the necessity of nutritional interventions for both PEM and over-nutrition in HD patients.

Main Methods:

• Review of recent studies on nutritional status, inflammation, and cardiovascular outcomes in hemodialysis patients.
• Analysis of metabolic abnormalities (hypertriglyceridemia, low HDL, glucose intolerance, visceral fat) in over-nourished HD patients.
• Examination of the correlation between plasma adiponectin, visceral fat mass, and cardiovascular events/mortality in HD patients.

Main Results:

• While obesity may not directly correlate with mortality, over-nutrition in HD patients is associated with adverse metabolic profiles.
• Low plasma adiponectin, inversely correlated with visceral fat, is linked to increased cardiovascular risk and mortality in HD patients.
• Both PEM and over-nutrition present significant nutritional challenges in the HD population.

Conclusions:

• Nutritional status, encompassing both PEM and over-nutrition, significantly impacts HD patient health.
• Metabolic derangements and low adiponectin in over-nourished HD patients highlight potential cardiovascular risks.
• Tailored nutritional therapy is essential for managing both under-nutrition and over-nutrition in hemodialysis patients to mitigate morbidity and mortality.
