The novel drug PX20606 activates the bile acid receptor FXR and shows beneficial effects in experimental liver cirrhosis: In the liver, it reduces scarring and inflammation, and also widens blood vessels. Thus, PX20606 leads to an improved blood flow through the liver and decreases hypertension of the portal vein. Additionally, PX20606 improves the altered intestinal barrier and decreases bacterial migration from the gut.

About two-thirds of male patients with cirrhosis show erectile dysfunction. Severity of liver dysfunction, portal hypertension, arterial hypertension and diabetes were identified as risk factors for erectile dysfunction.

Fat-based and glucose-based EN influence glucose homeostasis and insulin demand similarly, yet diet-induced thermogenesis was substantially higher in critically ill patients receiving fat-based enteral nutrition.

Aims: Endocrinological abnormalities, including low testosterone levels, are prevalent in cirrhosis. We assessed sexual hormone status in regard to hemodynamic abnormalities and its impact on hepatic decompensation and survival.Methods: Males with cirrhosis were prospectively included in this study since 2010. Sexual hormones including bioavailable testosterone, total testosterone, luteinizing hormone, folliclestimulating hormone, prolactin, and sex hormone-binding globulin as well as Child-Pugh score, Model for End-stage Liver Disease (MELD) score, and hepatic venous pressure gradient were recorded. Sarcopenia was also assessed in patients with available computed tomography scans. Clinical follow-up for hepatic decompensation, liver transplantation, and death was recorded until May 2017.Results: One hundred fourteen male cirrhotic patients were included: age 55 ± 9.4 years, MELD 13.5 (range, 7-20.7). Etiologies were alcoholic liver disease in 61(53.5%) patients, viral in 30 (26.3%) patients, and other in 23 (20.2%). Child-Pugh scores were A in 32 (28.1%) patients, B in 48 (42.1%), and C in 34 (29.8%). Levels of bioavailable testosterone and total testosterone decreased with advanced Child-Pugh score (P < 0.001 and P < 0.001) whereas prolactin increased (P = 0.002). Median bioavailable testosterone (0.8 ng/mL [0.1-2] vs. 1.68 ng/mL [0.07-2.65]; P = 0.004) and total testosterone (2.7 ng/mL [0.23-12.34] vs. 7 ng/mL [0.25-10]; P = 0.041) levels were lower in patients with severe portal hypertension (hepatic venous pressure gradient >12 mmHg). Median bioavailable testosterone (0.25 ng/mL [0.07-1.7] vs. 0.97 ng/mL [0.15-2.74)]; P = 0.017) and total testosterone levels (1.28 ng/mL [0.25-7.32] vs. 4.32 ng/mL [0.43-13.47]; P = 0.031) were significantly lower in sarcopenic patients. Median follow-up was 13 months (0.2-75 months) and liverrelated events were recorded in 46 patients (40.4%; death, 31 [27.2%]). Low total testosterone was associated with an increased risk for hepatic decompensation and/or death, even after adjusting for Child-Pugh score, MELD, and other relevant factors (Child-Pugh score model: hazard ratio 2.503, 95% confidence interval, 1.214-5.157, P = 0.013; MELD model: hazard ratio 3.065, 95% confidence interval, 1.523-6.169, P = 0.002).Conclusion: In parallel to increasing severity of cirrhosis, levels of testosterone decline whereas prolactin levels increase. However, low testosterone levels are independently associated with a higher risk for hepatic decompensation and mortality.
