Summary Background The safety of non‐selective β‐blockers in patients with advanced cirrhosis has been questioned in recent years. It was hypothesised that there is a particular therapeutic window. However, the specific limits still need to be determined. Aim To evaluate potential limits of the therapeutic window of non‐selective β‐blocker therapy in patients with cirrhosis and ascites Methods The impact of non‐selective β‐blockers on 28‐day transplant‐free survival was analysed in a cohort of 624 consecutive patients with decompensated cirrhosis and ascites. Three potential limits were investigated: spontaneous bacterial peritonitis, acute‐on‐chronic liver failure, mean arterial blood pressure ≤ 82 and < 65 mm Hg. Results Treatment with non‐selective β‐blockers was associated with a higher 28‐day transplant‐free survival in the overall cohort (hazard ratio: 0.621; P = .035) as well as in patients with acute‐on‐chronic liver failure (hazard ratio: 0.578; P = .031) and those with spontaneous bacterial peritonitis (hazard ratio: 0.594; P = .073). In contrast, survival benefits were markedly attenuated in patients with a mean arterial blood pressure ≤ 82 mm Hg and completely lost in those with mean arterial blood pressure < 65 mm Hg (P = .536). In spontaneous bacterial peritonitis patients with a mean arterial blood pressure < 65 mm Hg non‐selective β‐blocker treatment was associated with renal impairment. Of note, among those with a mean arterial blood pressure ≥ 65 mm Hg non‐selective β‐blocker intake was consistently associated with superior transplant‐free survival (hazard ratio: 0.582; P = .029) irrespective of the presence of spontaneous bacterial peritonitis (hazard ratio: 0.435; P = .028) or acute‐on‐chronic liver failure (hazard ratio: 0.480 P = .034). Conclusions Ascites, acute‐on‐chronic liver failure and spontaneous bacterial peritonitis do not limit the safe use of non‐selective β‐blockers in patients with cirrhosis. Mean arterial blood pressure might represent a better indicator to determine the therapeutic window of non‐selective β‐blocker treatment.

High dosages of proton pump inhibitors are associated with an adverse outcome in patients with spontaneous bacterial peritonitis. Thus, indication for high-dosage proton pump inhibitors therapy should be evaluated carefully in these patients.

IntroductionType 2 diabetes mellitus (DM) is a frequent comorbidity among patients with liver cirrhosis. However, data regarding the impact of DM on spontaneous bacterial peritonitis (SBP) are quite limited. Our aim was to analyze the impact of DM and HbA1c values on the incidence of SBP and mortality in patients with liver cirrhosis and ascites.MethodsA number of 475 consecutive patients with liver cirrhosis and ascites were analyzed. Presence of DM as well as HbA1c was assessed at the time of the first paracentesis. Patients were followed up for a mean of 266 days. Primary endpoints were SBP development and mortality.ResultsOverall, 118 (25%) patients were diagnosed with DM. DM patients had an increased risk for developing a SBP during follow-up (HR: 1.51; p = 0.03). SBP incidence was particularly high in DM patients with HbA1c values ≥6.4%, significantly higher than in DM patients with HbA1c values <6.4% (HR: 4.21; p = 0.0002). Of note, DM patients with HbA1c <6.4% at baseline had a similar risk for SBP as those without DM (HR: 0.93; p = 0.78, respectively). After excluding all patients who were eligible for secondary antibiotic prophylaxis, HbA1c ≥6.4% but neither bilirubin nor ascites protein level were associated with primary SBP development in the multivariate analysis (p = 0.003).ConclusionsIndividuals with liver cirrhosis and concomitant DM have a higher risk for developing a SBP. HbA1c values may be useful to further stratify the risk for SBP among DM patients, which may help to identify those who benefit from antibiotic prophylaxis.

In 2014, an analysis was conducted to evaluate the hepatitis C virus (HCV) epidemiology and disease burden in Germany. Since then, there have been considerable developments in HCV management such as the implementation of direct acting antivirals.The aim of this analysis was to assess the recent data available for Germany, establish an updated 2020 HCV prevalence and cascade of care and evaluate the impact of what-if scenarios on the future burden of disease using modelling analysis. A dynamic Markov model was used to forecast the HCV disease burden in Germany. Model inputs were retrieved through literature review, unpublished sources and expert input.Next, three "what-if" scenarios were developed to evaluate the status quo, COVID-19 pandemic, and steps needed to achieve the WHO targets for elimination. At the beginning of 2020, there were 189,000 (95% UI: 76,700-295,000) viremic infections in Germany, a decline of more than 85,000 viremic infections since 2012. Annual treatment starts went down since 2015. Compared with 2019, the COVID-19 pandemic resulted in a further 11% decline in 2020. If this continues for two years, it could result in 110 excess HCC cases and 200 excess liver related deaths by 2030. To achieve the

Summary Background Onset of refractory ascites is the hallmark of end‐stage liver disease. If liver transplantation (LTx) is not available and contraindications for a transjugular portosystemic shunt (TIPS) are present, repeated paracentesis remains the standard of care (SOC). Home‐based, tunnelled peritoneal catheters (PeCa) have been suggested as an alternative treatment option. However, data on patients with cirrhosis are scarce. Aim To evaluate the safety of PeCa in these patients compared to SOC. Methods Overall, 223 patients with cirrhosis, a contraindication for TIPS and refractory ascites were included in this retrospective study. PeCa implant was performed in 152 patients, whereas 71 were treated with SOC. Analysed end points included device explant‐free survival, mortality, acute kidney injury (AKI) and hyponatraemia. In the second approach, propensity score matching (PPSM) was performed to adjust for confounding factors. Results In patients with PeCa, median device explant‐free survival was 74 days and 52 explants were recorded within the first 90 days. Within 90 days, patients with PeCa had lower mortality than SOC (p = 0.11), and spontaneous bacterial peritonitis (SBP) incidence did not differ (p = 0.82). Regarding AKI and hyponatraemia, there was a trend towards a higher incidence in the PeCa group (p = 0.13 and p = 0.08), and the risk for rehospitalisation was higher in those with a PeCa (HR: 2.11, p = 0.04). After PPSM, mortality was lower in the PeCa group (HR:0.40; p = 0.03), whereas the incidence of SBP and hyponatraemia was comparable (p = 0.80 and p = 0.28) and AKI was more frequent in those with a PeCa (p = 0.08). Conclusion The implant of PeCa allows home‐based therapy of patients with cirrhosis and refractory ascites and a contraindication for TIPS. However, the risk for complications has to be considered and prospective studies are needed.

Background & aims Bacterial infections, in particular a spontaneous bacterial peritonitis (SBP), are a major threat in patients with liver cirrhosis. Recently, it has been shown that the impact on mortality might be underestimated by established risk-scores. Onset of infection was suggested to define a distinct stage of cirrhosis. However, it remains unclear whether all stages of decompensated cirrhosis are equally affected. Moreover, if there is such a distinct stage, it must be determined whether it is reversible after the infection has resolved. In this study we aimed to further analyze the impact of a current as well as a resolved SBP in different stages of decompensated liver cirrhosis. Methods A number of 579 patients with liver cirrhosis and ascites were included. MELD-score was used to determine the stage of liver disease. Low (<15), intermediate (15–25) and high (>25) MELD-groups were compared. Patients were followed up for 90 days. Primary endpoint was overall mortality. Statistical analyses were performed using the log-rank test, Cox regression and competing risk analysis. Results Mortality was significantly higher in patients with nosocomial-acquired SBP (nSBP) compared to patients without SBP (p<0.001;HR = 2.05). However, the most prominent difference in mortality was documented in the intermediate MELD-group (nSBP: p = 0.02;HR = 2.10). Importantly, mortality in nSBP patients remained increased even after the initial nSBP episode had resolved (p<0.01;HR = 1.90). Again, this was only significant in those with intermediate MELD-scores (p = 0.02;HR = 2.28). While a current as well as a resolved nSBP were significantly linked to a higher mortality, neither of them did increase the likelihood for liver transplantation. Conclusions Development of nSBP is independently associated with increased mortality supporting the concept of a distinct status of cirrhosis. Importantly, the prognosis remains unfavorable even after resolution of nSBP. This could be particularly relevant for patients with intermediate MELD-scores, who have limited chances for a donor liver.
