Muscle alterations (myosteatosis and sarcopenia) are frequent in cirrhosis and related to some complications including overt hepatic encephalopathy (HE). The aim of our study was to investigate the relationship between muscle alterations and minimal HE (MHE) and their role in the risk of overt HE. Sixty-four patients with cirrhosis were administered the Psychometric Hepatic Encephalopathy Score and animal naming test to detect MHE. Computed tomography was used to analyze the skeletal muscle index and attenuation. The incidence of the first episode of HE, taking into account the competing risk nature of the data, was estimated. Myosteatosis was observed in 24 patients (37.5%), sarcopenia in 37 (58%), and MHE in 32 (50%). Both myosteatosis (62.5% versus 12.5%, P < 0.001) and sarcopenia (84% versus 31%, P < 0.001) were more frequent in patients with MHE. The variables independently associated with the presence of MHE were sarcopenia, previous overt HE, and myosteatosis. Thirty-one (48%) patients developed overt HE over 16.1 ± 13 months; myosteatosis was detected in 68% and sarcopenia in 84% of them. Sarcopenia and myosteatosis were also independently associated with the development of overt HE. Venous ammonia was significantly higher in patients with sarcopenia (62.6 ± 17.7 versus 41.4 ± 16.1 μg/dL, P < 0.001) and in patients with myosteatosis (65.2 ± 19.2 versus 46.7 ± 17.1 μg/dL, P < 0.001) and inversely correlated to both parameters. Survival was significantly lower in malnourished patients compared to patients without myosteatosis or sarcopenia (P < 0.001). Conclusion: Myosteatosis and sarcopenia, probably by reducing the handling of ammonia in the muscle, are independently associated with MHE and the risk of overt HE in patients with cirrhosis; in malnourished patients, the amelioration of nutritional status may be a goal to decrease both the prevalence of MHE and the incidence of overt HE.

Early diagnosis and appropriate treatment of infections in cirrhosis are crucial because of their high morbidity and mortality. Multidrug-resistant (MDR) infections are on the increase in health care settings. Health-care–associated (HCA) infections are still frequently treated as community-acquired with a detrimental effect on survival. We aimed to prospectively evaluate in a randomized trial the effectiveness of a broad spectrum antibiotic treatment in patients with cirrhosis with HCA infections. Consecutive patients with cirrhosis hospitalized with HCA infections were enrolled. After culture sampling, patients were promptly randomized to receive a standard or a broad spectrum antibiotic treatment (NCT01820026). The primary endpoint was in-hospital mortality. Efficacy, side effects, and the length of hospitalization were considered. Treatment failure was followed by a change in antibiotic therapy. Ninety-six patients were randomized and 94 were included. The two groups were similar for demographic, clinical, and microbiological characteristics. The prevalence of MDR pathogens was 40% in the standard versus 46% in the broad spectrum group. In-hospital mortality showed a substantial reduction in the broad spectrum versus standard group (6% vs. 25%; P = 0.01). In a post-hoc analysis, reduction of mortality was more evident in patients with sepsis. The broad spectrum showed a lower rate of treatment failure than the standard therapy (18% vs. 51%; P = 0.001). Length of hospitalization was shorter in the broad spectrum (12.3 ± 7 days) versus standard group (18 ± 15 days; P = 0.03). Five patients in each group developed a second infection during hospitalization with a similar prevalence of MDR (50% broad spectrum vs. 60% standard). Conclusions: A broad spectrum antibiotic therapy as empirical treatment in HCA infections improves survival in cirrhosis. This treatment was significantly effective, safe, and cost saving.
