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 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. Hospitalized and outpatients (CHUM’s Liver Unit in Montreal, Canada) with liver cirrhosis of different etiologies and 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). 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 (13A, 9B, 5C and 6N/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. Furthermore, cirrhotic malnourished patients show decreased HRQOL compared to well-nourished cirrhotic patients (p<0.01). Cirrhotic patients, when compared to controls, displayed a lower score in physical functioning (p=0.03) and general health (p=0.03). CHESS analysis revealed none of the cirrhotic patients had HE while 21% of them had an HE diagnosis in medical chart, suggesting CHESS would not be sensible enough to screen HE. Our preliminary results suggest that nutritional status does influence particular domains of HRQOL in cirrhotic patients irrespective 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.
