Malnutrition in Hepatorenal Syndrome Associated with Liver Cirrhosis

Abstract

Malnutrition is a prevalent and significant comorbidity among individuals diagnosed with liver cirrhosis, often exacerbated by the onset of hepatorenal syndrome. The objective of this narrative literature review is to explore the complex relationship between malnutrition, liver cirrhosis, and hepatorenal syndrome, highlighting the factors that contribute to malnutrition, its effects on the pathophysiology of hepatorenal syndrome, and the implications for clinical practice. The review highlights the high prevalence of malnutrition among patients with liver cirrhosis, particularly those who develop hepatorenal syndrome. It identifies key characteristics of malnutrition in this population, including sarcopenia, depleted protein stores, and micronutrient deficiencies. These nutritional deficits significantly impair immune function, increase susceptibility to infections, and adversely affect both renal and liver function. The paper also notes that the inflammatory response associated with cirrhosis and renal dysfunction exacerbates catabolic processes, worsening nutritional deficiencies and underscoring the need for targeted nutritional interventions in this vulnerable patient group. Additionally, malnutrition adversely affects the efficacy of therapeutic interventions and increases the risk of complications, including infections and elevated mortality rates. Emerging evidence suggests that while implementing targeted nutritional support in the context of hepatorenal syndrome presents challenges, it is essential for improving patient outcomes. Therefore, the early identification of malnutrition and the proactive application of nutritional strategies are critical for enhancing the management of renal impairment in patients with liver cirrhosis.
