Sarcopenia evaluated by EASL/AASLD computed tomography-based criteria predicts mortality in patients with cirrhosis: A systematic review and meta-analysis.

Background & Aims: Sarcopenia is associated with increased morbidity and mortality in patients with cirrhosis, but its definition in current literature is very heterogeneous. We performed a systematic review and meta-analysis to assess the association between mortality and sarcopenia evaluated by computed tomography (CT) in patients with cirrhosis, both overall and stratified for the criteria used to define sarcopenia. Methods: Medline, Embase, Scopus, and Cochrane Library were searched up to January 2023. We included studies assessing sarcopenia presence with CT scans and providing data on the risk of mortality. Adjusted hazard ratios (HRs) and 95% CIs were pooled using a random-effects model. Results: Thirty-nine studies comprising 12,827 patients were included in the meta-analysis. The summary prevalence of sarcopenia was 44% (95% CI 38-50%). The presence of sarcopenia (any definition) was an independent predictor of mortality with an adjusted HR of 2.07 (95% CI 1.81-2.36), and the result was consistent in all subgroup analyses. The prognostic role of the EASL/AASLD criteria was confirmed for the first time with an HR of 1.86 (95% CI 1.53-2.26) (n = 14 studies). The cut-offs used to define sarcopenia based on psoas muscle parameters varied among studies, thus, a subgroup analysis was not feasible. There was no substantial heterogeneity for the main estimates and no significant risk of publication bias. Conclusions: Sarcopenia on CT is associated with a 2-fold higher risk of mortality in patients with cirrhosis. The cut-offs proposed by EASL/AASLD are prognostically relevant and should be the recommended criteria used to define sarcopenia in clinical practice. Impact and implications: Sarcopenia assessed by the reference standard (computed tomography scan) is an independent predictor of mortality in patients with cirrhosis, with a 2-fold increase in the risk of death in all sensitivity analyses. This finding is particularly valid in patients from Europe and North America, and in transplant candidates. Stratifying for the parameters and cut-offs used, we confirmed for the first time the prognostic impact of the definition proposed by EASL/AASLD, supporting their use in clinical practice. Psoas muscle assessment is promising, but data are still limited and too heterogeneous to recommend its routine use at present.

Hepatic Venous Pressure Gradient: Measurement and Pitfalls.

Measurement of hepatic venous pressure gradient (HVPG) effectively mirrors the severity of portal hypertension (PH) and offers valuable insights into prognosis of liver disease, including the risk of decompensation and mortality. Additionally, HVPG offers crucial information about treatment response to nonselective beta-blockers and other medications, with its utility demonstrated in clinical trials in patients with PH. Despite the widespread dissemination and validation of noninvasive tests, HVPG still holds a significant role in hepatology. Physicians treating patients with liver diseases should comprehend the HVPG measurement procedure, its applications, and how to interpret the results and potential pitfalls.

Improving primary prophylaxis of variceal bleeding by adapting therapy to the clinical stage of cirrhosis. A competing-risk meta-analysis of individual participant data.

BACKGROUND & AIMS: Non-selective ß-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis. METHODS: By systematic review, we identified RCTs comparing NSBBs vs EVL, in monotherapy or combined, for primary bleeding prevention. We performed a competing-risk, time-to-event meta-analysis, using individual patient data (IPD) obtained from principal investigators of RCTs. Analyses were stratified according to previous decompensation of cirrhosis. RESULTS: Of 25 RCTs eligible, 14 failed to provide IPD and 11 were included, comprising 1400 patients (656 compensated, 744 decompensated), treated with NSBBs (N = 625), EVL (N = 546) or NSBB+EVL (N = 229). Baseline characteristics were similar between groups. Overall, mortality risk was similar with EVL vs. NSBBs (subdistribution hazard-ratio (sHR) = 1.05, 95% CI = 0.75-1.49) and with EVL + NSBBs vs either monotherapy, with low heterogeneity (I2 = 28.7%). In compensated patients, mortality risk was higher with EVL vs NSBBs (sHR = 1.76, 95% CI = 1.11-2.77) and not significantly lower with NSBBs+EVL vs NSBBs, without heterogeneity (I2 = 0%). In decompensated patients, mortality risk was similar with EVL vs. NSBBs and with NSBBs+EVL vs. either monotherapy. CONCLUSIONS: In patients with compensated cirrhosis and high-risk varices on primary prophylaxis, NSBBs significantly improved survival vs EVL, with no additional benefit noted adding EVL to NSBBs. In decompensated patients, survival was similar with both therapies. The study suggests that NSBBs are preferable when advising preventive therapy in compensated patients.

Transjugular intrahepatic portosystemic shunt in patients with hepatocellular carcinoma: A systematic review.

BACKGROUND/AIMS: Transjugular intrahepatic portosystemic shunts (TIPS) in patients with hepatocellular carcinoma (HCC) may improve access to curative therapies, treat portal hypertension (PH)-related complications without worsening liver function, and increase overall survival. Data on the efficacy and safety of TIPS to treat PH complications in HCC patients, as well as the HCC treatment response, were evaluated. METHODS: Studies reporting efficacy in controlling bleeding/ascites or response to HCC therapy, safety, and survival in patients with HCC and TIPS were searched systematically on PubMed and Embase. An extraction of articles using predefined data fields and quality indicators was used. RESULTS: We selected 19 studies and found 937 patients treated for ascites/bleeding and 177 evaluating HCC treatment response. Over half were under 5 cm and solitary lesions, and most studies included tumours with portal vein thrombosis. Regarding PH studies, TIPS resolved bleeding/ascites in >60% of patients, more effective for bleeding. There were no lethal complications reported and procedural bleeding occurred in <5%. Hepatic encephalopathy occurred in 15%-30% within three months. In the HCC treatment-response studies, major complication rates were low with no mortality. In the studies that evaluated the response to transarterial chemoembolization, complete response rate of patients with TIPS varied from 16% to 75%. Liver transplantation rate varied from 8% to 80%, with >40% rate in half of the studies. CONCLUSIONS: In the published studies, TIPS is effective in treating PH complications in patients with HCC. Prospective studies on TIPS placement in patients with HCC are urgently needed to evaluate the efficacy and safety of TIPS in this setting.

Non-invasive tools for compensated advanced chronic liver disease and portal hypertension after Baveno VII - an update.

Non-invasive tests (NITs) and liver stiffness measurement (LSM) in particular, have entered clinical practice over 20 years ago as point-of-care tests to diagnose liver fibrosis in patients with compensated chronic liver disease. Since then, NITs use has evolved thanks to a large number of studies in all major etiologies of liver disease, and they have become important tools to stratify the risk of portal hypertension and liver-related events. The Baveno VII consensus workshop provided several novel recommendations regarding the use of well-established and novel NITs in the specific setting of portal hypertension screening, diagnosis and follow-up. The Baveno VII expert panels paid special attention to summarizing the existing data into simple clinical rules able to guide clinicians in their practice. The "rule of five" for LSM is a tool to stratify the risk of liver-related events, and LSM alone or in combination with platelet count, can be used now to rule-in and rule-out compensated advanced chronic liver disease (cACLD) and clinically significant portal hypertension, as well as to rule-out high-risk varices. Use of NITs in obese subjects with non-alcoholic fatty liver disease (NAFLD) and patients with viral hepatitis C that has been successfully treated, require specific knowledge. This review will update the reader on these aspects.

Mycophenolate mofetil as second line treatment in autoimmune hepatitis - A retrospective single center analysis.

Background: Most patients with autoimmune hepatitis respond to standard treatment with steroids and azathioprine. While the disease is usually fatal if untreated, patients who respond well to therapy have an excellent prognosis. Nevertheless, second-line treatment is necessary in approximately 20% of patients, due to either intolerance or insufficient response to first line treatment.While data for mycophenolate mofetil (MMF) in patients intolerant to azathioprine is encouraging, MMF seems of less benefit in patients with insufficient response to first line treatment, but analyzed data on this issue is limited. Aim: To evaluate the efficacy and safety of MMF as a second-line therapy in patients with AIH. Methods: Retrospective analysis of a monocentric database of AIH patients who received medical care from 2000 to 2022. Clinical, immunological and biochemical parameters were assessed at different time points including last follow-up. Results: Overall, 144 patients with AIH were identified. Fifty out of 144 (35%) AIH patients received MMF. Forty (80%) received MMF due to first line treatment intolerance, while ten (20%) due to insufficient response to first line treatment.Remission with MMF monotherapy was 81.5% in the intolerance group versus 30% in the insufficient response group. Patients switched to MMF because of an insufficient response, more often needed additional prednisolone doses higher than 5 mg/day, a switch to third-line treatment or combination regiments, to achieve disease control. Conclusions: Patients treated with MMF because of intolerance to first line treatment show a good disease control under MMF in the majority of cases. Efficacy is considerably lower in the patients switched to MMF because of an insufficient response to first line treatment.

Investigational drugs in early clinical development for portal hypertension.

INTRODUCTION: Advanced chronic liver disease is considered a reversible condition after removal of the primary etiological factor. This has led to a paradigm shift in which portal hypertension (PH) is a reversible complication of cirrhosis. The pharmacologic management of PH is centered on finding targets to modify the natural history of cirrhosis and PH. AREAS COVERED: This paper offers an overview of the use of pharmacological strategies in early clinical development that modify PH. Papers included were selected from searching clinical trial sites and PubMed from the last 10 years. EXPERT OPINION: A paradigm shift has generated a new concept of PH in cirrhosis as a reversible complication of a potentially curable disease. Decreasing portal pressure to prevent decompensation and further complications of cirrhosis that may lead liver transplantation or death is a goal. Therapeutic strategies also aspire achieve total or partial regression of fibrosis, thus eliminating the need for treatment or screening of PH.

Carvedilol reduces the risk of decompensation and mortality in patients with compensated cirrhosis in a competing-risk meta-analysis.

BACKGROUND & AIMS: Whether non-selective ß-blockers can prevent decompensation of cirrhosis warrants clarification. Carvedilol might be particularly effective since its intrinsic vasodilatory activity may ameliorate hepatic vascular resistance, a major mechanism of portal hypertension in early cirrhosis. We assessed whether carvedilol may prevent decompensation and improve survival in patients with compensated cirrhosis and clinically significant portal hypertension (CSPH). METHODS: By systematic review we identified randomized-controlled trials (RCTs) comparing carvedilol vs. control therapy (no-active treatment or endoscopic variceal ligation [EVL]) in patients with cirrhosis and CSPH without previous bleeding. We performed a competing-risk time-to-event meta-analysis using individual patient data (IPD) obtained from principal investigators of RCTs. Only compensated patients were included. Primary outcomes were prevention of decompensation (liver transplantation and death were competing events) and death (liver transplantation was a competing event). Models were adjusted using propensity scores for baseline covariates with the inverse probability of treatment weighting (IPTW) approach. RESULTS: Among 125 full-text studies evaluated, 4 RCTs were eligible. The 4 provided IPD and were included, comprising 352 patients with compensated cirrhosis, 181 treated with carvedilol and 171 controls (79 received EVL and 92 placebo). Baseline characteristics were similar between groups. Standardized differences were <10% by IPTW. The risk of developing decompensation of cirrhosis was lower with carvedilol than in controls (subdistribution hazard ratio [SHR] 0.506; 95% CI 0.289-0.887; p = 0.017; I2 = 0.0%, Q-statistic-p = 0.880), mainly due to a reduced risk of ascites (SHR 0.491; 95% CI 0.247-0.974; p = 0.042; I2 = 0.0%, Q-statistic-p = 0.384). The risk of death was also lower with carvedilol (SHR 0.417; 95% CI 0.194-0.896; p = 0.025; I2 = 0.0%, Q-statistic-p = 0.989). CONCLUSIONS: Long-term carvedilol therapy reduced decompensation of cirrhosis and significantly improved survival in compensated patients with CSPH. This suggests that screening patients with compensated cirrhosis for CSPH to enable the prompt initiation of carvedilol could improve outcomes. PROSPERO REGISTRATION NUMBER: CRD42019144786. LAY SUMMARY: The transition from compensated cirrhosis to decompensated cirrhosis is associated with markedly reduced life expectancy. Therefore, preventing decompensation in patients with compensated cirrhosis would be associated with greatly improved patient outcomes. There has been controversy regarding the use of non-selective ß-blockers (portal pressure-lowering medications) in patients with cirrhosis and elevated portal blood pressure (portal hypertension). Herein, using a competing-risk meta-analysis to optimize sample size and properly investigate cirrhosis as a multistate disease and outcomes as time-dependent events, we show that carvedilol (a non-selective ß-blocker) is associated with a reduced risk of decompensating events and improved survival in patients with cirrhosis and portal hypertension.

Current treatment options of refractory ascites in liver cirrhosis - A systematic review and meta-analysis.

BACKGROUND: Refractory ascites is a severe complication of liver cirrhosis and treatment options consist in large volume paracentesis, transjugular intrahepatic portosystemic shunt, alfapump®, peritoneovenous shunt and permanent indwelling peritoneal catheter. AIM: Our aim was to assess the efficacy, mortality and complications of each treatment. METHODS: We performed a systematic review using Pubmed and Embase. Frequencies were summarized with Comprehensive Meta-Analysis Software. RESULTS: Seventy-seven studies were included. In patients with transjugular intrahepatic portosystemic shunt, 1-year mortality was 33% (95% CI 0.29-0.39, I2=82.1; τ2 = 0.37; p<0.001) with lower mortality in newer studies (26% vs. 44%). At 6 months, mortality in patients with alfapump® was 24% (95% CI 0.16-0.33, I2=0.00; τ2 = 0.00; p = 0.83), 31% developed acute kidney injury (95% CI 0.18-0.48, I2=44.0; τ2 = 0.22; p = 0.15). Mortality at 12 months was 44% (95% CI 32%-58%, I2=76.7, τ2 = 0.44, p<0.001) in peritoneovenous shunts and 45% (95% CI 38%-53%, I2=61.4, τ2 = 0.18, p = 0.003) in large volume paracentesis, respectively. Overall mortality in patients with permanent indwelling catheters was 66% (95% CI 33%-89%, I2=82.5, τ2 = 1.57, p = 0.001). DISCUSSION: Mortality in patients with transjugular intrahepatic portosystemic shunt was lower in newer studies, probably due to a better patient selection. Acute kidney injury was frequent in patients with alfapump®. Permanent indwelling catheters seemed to be a good option in a palliative setting.

Inflammatory activity affects the accuracy of liver stiffness measurement by transient elastography but not by two-dimensional shear wave elastography in non-alcoholic fatty liver disease.

BACKGROUND: In patients with non-alcoholic fatty liver disease (NAFLD), the impact of the severity of steatosis and inflammatory activity on the accuracy of liver stiffness measurement (LSM) by transient elastography (TE) and by two-dimensional shear wave elastography (2D-SWE) in staging liver fibrosis is still debated and scarce. We aimed to focus on this aspect. METHODS: We prospectively studied 104 patients requiring biopsy for the assessment of NAFLD. We used ordinary least squares regression to test for differences in the association between fibrosis and LSM by TE and 2D-SWE when other factors (steatosis and inflammatory activity) are considered. RESULTS: Among 104 patients, 102 had reliable LSM by TE, and 88 had valid LSM by 2D-SWE. The association between fibrosis based on histology and LSM was significantly stronger when 2D-SWE assessed LSM compared to TE (Spearman's correlation coefficient of .71; P < .001 vs .51, P < .001; Z = 2.21, P = .027). Inflammatory activity was an independent predictor of LSM by TE but not of LSM by 2D-SWE. After controlling for fibrosis, age, sex and body mass index, the inflammatory activity and the interaction between inflammatory activity and fibrosis independently explained 11% and 13% of variance in LSM by TE respectively. Steatosis did not affect the association of fibrosis and LSM by either method. CONCLUSION: Inflammatory activity on histology significantly affects LSM by TE, but not LSM by 2D-SWE in NAFLD. LSM by 2D-SWE reflects liver fibrosis more accurately than LSM by TE. Furthermore, the severity of steatosis on histology did not influence the association of LSM and fibrosis by either elastography method.

Noninvasive Diagnosis of Portal Hypertension in Patients With Compensated Advanced Chronic Liver Disease.

INTRODUCTION: We aimed to explore the prevalence of portal hypertension in the most common etiologies of patients with compensated advanced chronic liver disease (cACLD) and develop classification rules, based on liver stiffness measurement (LSM), that could be readily used to diagnose or exclude clinically significant portal hypertension (CSPH) in clinical practice. METHODS: This is an international cohort study including patients with paired LSM/hepatic venous pressure gradient (HVPG), LSM ≥10 kPa, and no previous decompensation. Portal hypertension was defined by an HVPG >5 mm Hg. A positive predictive value ≥90% was considered to validate LSM cutoffs for CSPH (HVPG ≥10 mm Hg), whereas a negative predictive value ≥90% ruled out CSPH. RESULTS: A total of 836 patients with hepatitis C (n = 358), nonalcoholic steatohepatitis (NASH, n = 248), alcohol use (n = 203), and hepatitis B (n = 27) were evaluated. Portal hypertension prevalence was >90% in all cACLD etiologies, except for patients with NASH (60.9%), being even lower in obese patients with NASH (53.3%); these lower prevalences of portal hypertension in patients with NASH were maintained across different strata of LSM values. LSM ≥25 kPa was the best cutoff to rule in CSPH in alcoholic liver disease, chronic hepatitis B, chronic hepatitis C, and nonobese patients with NASH, whereas in obese NASH patients, the positive predictive value was only 62.8%. A new model for patients with NASH (ANTICIPATE-NASH model) to predict CSPH considering body mass index, LSM, and platelet count was developed, and a nomogram was constructed. LSM ≤15 kPa plus platelets ≥150 × 10/L ruled out CSPH in most etiologies. DISCUSSION: Patients with cACLD of NASH etiology, especially obese patients with NASH, present lower prevalences of portal hypertension compared with other cACLD etiologies. LSM ≥25 kPa is sufficient to rule in CSPH in most etiologies, including nonobese patients with NASH, but not in obese patients with NASH.

Noninvasive Detection of Clinically Significant Portal Hypertension in Compensated Advanced Chronic Liver Disease.

Patients with compensated advanced chronic liver disease have different prognoses depending on the presence of portal hypertension. Current non-invasive diagnostic methods allow identification of clinically significant portal hypertension. Portosystemic collaterals on imaging or liver stiffness of more than 20 to 25 kPa by using transient elastography identifies patients with clinically significant portal hypertension. Patients with liver stiffness of less than 20 kPa and platelet count of greater than 150 g/L can avoid endoscopy. This rule could be expanded using spleen stiffness. Methods to risk stratify for portal hypertension in compensated advanced chronic liver disease and successfully treated chronic hepatitis C and B are subject of research.

Malnutrition and Alcohol in Patients Presenting with Severe Complications of Cirrhosis After Laparoscopic Bariatric Surgery.

Factors and outcomes associated with decompensation of liver disease and liver failure in obese patients who underwent modern bariatric surgery are unclear. We present here a cohort of seventeen consecutive patients referred because of decompensation of liver disease following laparoscopic bariatric surgery. All patients showed signs of malnutrition (sarcopenia in 76.5%). In ten (58.8%), decompensation was associated with alcohol ingestion, which started after bariatric surgery in six patients. One patient died and three patients required liver transplantation, in one case preceded by transjugular intrahepatic portosystemic shunt (TIPS). However, thirteen patients achieved stabilization or full re-compensation with medical therapy and nutritional support. Our cases underline the risk of alcohol intake and malnutrition after laparoscopic bariatric surgery as causes of severe liver decompensation and underline the need for careful interdisciplinary care of these patients after surgery to early identify and treat alcohol misuse, malnutrition, and liver disease.

Royal Free Hospital-estimated glomerular filtration rate for prognostic stratification of first acute kidney injury in cirrhosis.

BACKGROUND & AIMS: Renal function is a major determinant of prognosis in patients with cirrhosis. Current guidelines only contemplate serum creatinine (sCr) to assess kidney injury. However, there are formulas to estimate glomerular filtration rate (eGFR) which better measure renal function in patients listed for liver transplantation. There is no data available on whether these formulas predict prognosis in patients with acute kidney injury (AKI). METHODS: In 143 patients presenting with a first episode of AKI, we compared the prognostic value of renal function estimated using sCr or eGFR assessed with Modification of Diet in Renal Disease (MDRD-6), chronic kidney disease epidemiology (CKD-EPI) and Royal Free Hospital (RFH) for renal replacement therapy (RRT) within 30 days of AKI, and 30- and 90-day transplant-free survival. RESULTS: eGFR was calculated on values obtained before and at admission, at presentation of AKI (D0) and 48 hours after AKI (D2).15% of patients (more commonly in alcohol + metabolic etiology; P = .049 vs other) required RRT. Transplant-free survival at 30-and 90-day were 77% and 63%. Among sCr, MDRD-6, CKD-EPI and RFH-eGFR, the latter predicted best RRT (HR 0.937 95% CI 0.893-0.982, P = .007), 30-d (HR 0.936 95% CI 0.901-0.972, P = .001) and 90-d (HR 0.934 95% CI 0.908-0.972, P < .001) mortality/OLT. CONCLUSIONS: Renal function estimated using the RFH-eGFR calculated at D2 after AKI diagnosis is a strong predictor of RRT and of 30-d and 90-d transplant-free survival. Results suggest that in cirrhosis, RFH-eGFR may be a better indicator of prognosis in AKI than sCr.

Effect of poorly absorbable antibiotics on hepatic venous pressure gradient in cirrhosis: A systematic review and meta-analysis.

BACKGROUND: The effects of poorly/non-absorbable antibiotics on hepatic venous pressure gradient (HVPG) are debated. AIM: To analyze the effects of rifaximin or norfloxacin on HVPG and on markers of bacterial translocation and proinflammatory cytokines. METHODS: We performed a systematic search of randomized clinical trials (RCTs) involving patients with cirrhosis and portal hypertension, assessing the effect of rifaximin or norfloxacin vs control on HVPG. Pooled analyses were based on random-effects models, heterogeneity was assessed by Cochran's Q, I2 statistic and subgroup analyses. RESULTS: Five studies (215 patients) were included. Risk of bias was high in three. We found no significant differences using antibiotics versus control. The summary mean difference in HVPG was of -0.55 mmHg (95%CI:-1.52, 0.42; P = 0.27), with moderate heterogeneity (P = 0.15; I2 = 40%). RCTs with longer therapy (60-90 days) used non-selective-beta-blockers (NSBB) in both antibiotics and control arms. Subgroup analysis showed a significantly greater reduction in HVPG in the combination arm over controls (mean difference -1.46 mmHg [95%CI: -2.63, -0.28; P = 0.01]) with no heterogeneity (P = 0.46; I2 = 0%). Serum lipopolysaccharide-binding protein (LBP) significantly decreased with antibiotics, but with high heterogeneity (P < 0.001; I2 = 92%). CONCLUSIONS: Rifaximin or norfloxacin did not significantly reduce HVPG in patients with cirrhosis and portal hypertension. Studies using antibiotic for longer periods on top of NSBB showed a significant decrease in HVPG.

Transjugular intrahepatic portosystemic shunt and alfapump® system for refractory ascites in liver cirrhosis: Outcomes and complications.

BACKGROUND: Treatment of refractory ascites in liver cirrhosis is challenging. Transjugular intrahepatic portosystemic shunt and alfapump® have been proposed for the management, but few data comparing both exist. AIMS: The aim of this study was to evaluate the characteristics and outcomes of patients treated with transjugular intrahepatic portosystemic shunt and alfapump® for refractory ascites at our centre. METHODS: All consecutive patients were retrospectively reviewed for baseline characteristics, efficacy of treatment, complications and survival. RESULTS: In total, 19 patients with transjugular intrahepatic portosystemic shunt and 40 patients with alfapump® were included. Patients with transjugular intrahepatic portosystemic shunt had better liver function and less hepatic encephalopathy at baseline. Fifty-eight per cent of patients developed hepatic encephalopathy in the first six months after transjugular intrahepatic portosystemic shunt. In patients with alfapump®, renal function decreased and 58% developed prerenal impairment and 43% hepatorenal syndrome in the first six months. Alfapump® patients with new catheters required less reinterventions (26% versus 57% with old catheters, p = 0.049). Transplant-free survival at 1 year was 25% in alfapump® and 65% in transjugular intrahepatic portosystemic shunt. Hepatic encephalopathy predicted transplant-free survival in patients with alfapump® (hazard ratio 2.00, 95% confidence interval 0.99-4.02, p = 0.05). In a sensitivity analysis comparing patients with similar liver function, the rate of hepatorenal syndrome and prerenal impairment was higher in patients with alfapump® and these patients were hospitalised more frequently, whereas the rate of hepatic encephalopathy was similar in both treatment groups. CONCLUSIONS: Both transjugular intrahepatic portosystemic shunt and alfapump® were effective treatments for refractory ascites in cirrhosis. Patients treated with transjugular intrahepatic portosystemic shunt had a better one-year transplant-free survival but had less negative prognostic factors at baseline. Selecting patients without hepatic encephalopathy prior to implantation of an alfapump® might improve transplant-free survival.

Beta-blockers in cirrhosis: Evidence-based indications and limitations.

Non-selective beta-blockers (NSBBs) are the mainstay of treatment for portal hypertension in the setting of liver cirrhosis. Randomised controlled trials demonstrated their efficacy in preventing initial variceal bleeding and subsequent rebleeding. Recent evidence indicates that NSBBs could prevent liver decompensation in patients with compensated cirrhosis. Despite solid data favouring NSBB use in cirrhosis, some studies have highlighted relevant safety issues in patients with end-stage liver disease, particularly with refractory ascites and infection. This review summarises the evidence supporting current recommendations and restrictions of NSBB use in patients with cirrhosis.
