Background: Malnutrition is an important prognostic factor potentially influencing clinical outcome of patients suffering from chronic liver disease (cirrhosis; CLD). Malnutrition may increase the risk of developing other complications including hepatic encephalopathy (HE). Malnutrition in cirrhosis may also affect patient’s functional status and wellbeing or health-related quality of life (HRQOL). Management strategies focussing on nutritional status in relation to complications of cirrhosis are an unmet clinical need. We hypothesize sub-optimal nutritional status in cirrhotic patients increases the risk of developing HE and decreases HRQOL. Methods: 33 patients (outpatients and hospitalized; CHUM’s Liver Unit in Montreal, Canada) with liver cirrhosis of different etiologies and 13 healthy controls were assessed for 1) Nutritional status (Subjective Global Assessment (SGA)); 2) HE (Clinical HE Staging Scale (CHESS)); 3) HRQOL (Short-Form-36 (SF-36) questionnaire). Results: This on-going prospective study included 33 cirrhotic patients (58% men) of various etiologies (30% alcohol, 33 % virus, 27% NASH and 33% others), Child-Pugh A/B/C (13A, 9B, 5C and 6 N/A), mean age 55,7±12,9 as well as 13 healthy controls (46% men, mean age 49,4±14,9). SGA analysis revealed that 27% of cirrhotic patients were malnourished in which 22% of them malnourished showed signs of HE as assessed by CHESS. Cirrhotic patients, when compared to controls, displayed a lower score in physical functioning (p=0.03) and general health (p=0.03), both part of the physical health domain of SF-36. Furthermore, cirrhotic malnourished patients show decreased physical aspects of HRQOL compared to well-nourished cirrhotic patients (p<0.01). Conclusion: Our preliminary results suggest that nutritional status does influence particular domains of HRQOL in cirrhotic patients irrelevant of their etiology. Further patients are required to statistically confirm the impact of nutritional status on HE and HRQOL in cirrhotic patients. Identifying factors associated with nutritional status, HRQOL and HE in cirrhotic patients may help improve patient care and guide future research.
