Meta-Analysis
BACKGROUND & AIMS
Whether non-selective β-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; I = 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; I = 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; I = 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.

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 β-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 β-blocker) is associated with a reduced risk of decompensating events and improved survival in patients with cirrhosis and portal hypertension.

BACKGROUND AND AIM
Alagille syndrome (ALGS) is an inherited multisystem disorder typically manifesting as cholestasis, and potentially leading to end-stage liver disease and death. The aim of the study was to perform the first systematic review of the epidemiology, natural history, and burden of ALGS with a focus on the liver component.
METHODS
Electronic databases and proceedings from key congresses were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 guidelines. This analysis included publications reporting epidemiology, natural history, economic burden or health-related quality of life (HRQoL) outcomes in patients with ALGS.
RESULTS
Of 525 screened publications, 20 met the inclusion criteria. Liver-related features included cholestasis (87%-100% of patients), jaundice (66%-85%), and cirrhosis (44%-95%). Between 15% and 47% of patients underwent liver transplantation and 4% to 14% received partial biliary diversion. Pruritus affected the majority of patients (59%-88%, of whom up to 45% had severe pruritus) and manifested during the first 10 years of life. Children with ALGS had significantly impaired HRQoL compared with healthy controls and those with other diseases. Itching was the symptom that most affected children with ALGS. No study assessed the economic burden of ALGS.
CONCLUSIONS
Our findings consolidate information on the clinical course of ALGS, and highlight gaps in knowledge, most notably the absence of any research on the economic consequences of the disease. Further research is needed to establish the incidence of genetically confirmed ALGS. Disease-specific tools are also needed to improve the measurement of symptoms, such as itching, and better understand the impact of ALGS on HRQoL.

BACKGROUND
Bile duct injury (BDI) is a devastating complication following cholecystectomy. After initial management of BDI, patients stay at risk for late complications including anastomotic strictures, recurrent cholangitis, and secondary biliary cirrhosis.
METHODS
We provide a comprehensive overview of current literature on the long-term outcome of BDI. Considering the availability of only limited data regarding treatment of anastomotic strictures in literature, we also retrospectively analyzed patients with anastomotic strictures following a hepaticojejunostomy (HJ) from a prospectively maintained database of 836 BDI patients.
RESULTS
Although clinical outcomes of endoscopic, radiologic, and surgical treatment of BDI are good with success rates of around 90%, quality of life (QoL) may be impaired even after "clinically successful" treatment. Following surgical treatment, the incidence of anastomotic strictures varies from 5 to 69%, with most studies reporting incidences around 10-20%. The median time to stricture formation varies between 11 and 30 months. Long-term BDI-related mortality varies between 1.8 and 4.6%. Of 91 patients treated in our center for anastomotic strictures after HJ, 81 (89%) were treated by percutaneous balloon dilatation, with a long-term success rate of 77%. Twenty-four patients primarily or secondarily underwent surgical revision, with recurrent strictures occurring in 21%.
CONCLUSIONS
The long-term impact of BDI is considerable, both in terms of clinical outcomes and QoL. Treatment should be performed in tertiary expert centers to optimize outcomes. Patients require a long-term follow-up to detect anastomotic strictures. Strictures should initially be managed by percutaneous dilatation, with surgical revision as a next step in treatment.

Meta-Analysis
BACKGROUNDS & AIMS
Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intrahepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology. We undertook the largest GWMA of PBC to date, aiming to identify additional risk loci and prioritise candidate genes for in silico drug efficacy screening.
METHODS
We combined new and existing genotype data for 10,516 cases and 20,772 controls from 5 European and 2 East Asian cohorts.
RESULTS
We identified 56 genome-wide significant loci (20 novel) including 46 in European, 13 in Asian, and 41 in combined cohorts; and a 57 genome-wide significant locus (also novel) in conditional analysis of the European cohorts. Candidate genes at newly identified loci include FCRL3, INAVA, PRDM1, IRF7, CCR6, CD226, and IL12RB1, which each play key roles in immunity. Pathway analysis reiterated the likely importance of pattern recognition receptor and TNF signalling, JAK-STAT signalling, and differentiation of T helper (T)1 and T17 cells in the pathogenesis of this disease. Drug efficacy screening identified several medications predicted to be therapeutic in PBC, some of which are well-established in the treatment of other autoimmune disorders.
CONCLUSIONS
This study has identified additional risk loci for PBC, provided a hierarchy of agents that could be trialled in this condition, and emphasised the value of genetic and genomic approaches to drug discovery in complex disorders.
LAY SUMMARY
Primary biliary cholangitis (PBC) is a chronic liver disease that eventually leads to cirrhosis. In this study, we analysed genetic information from 10,516 people with PBC and 20,772 healthy individuals recruited in Canada, China, Italy, Japan, the UK, or the USA. We identified several genetic regions associated with PBC. Each of these regions contains several genes. For each region, we used diverse sources of evidence to help us choose the gene most likely to be involved in causing PBC. We used these 'candidate genes' to help us identify medications that are currently used for treatment of other conditions, which might also be useful for treatment of PBC.

Meta-Analysis Review
BACKGROUND
Non-selective beta-blockers are recommended for the prevention of bleeding in people with cirrhosis, portal hypertension and gastroesophageal varices. Carvedilol is a non-selective beta-blocker with additional intrinsic alpha-blocking effects, which may be superior to traditional, non-selective beta-blockers in reducing portal pressure and, therefore, in reducing the risk of upper gastrointestinal bleeding.
OBJECTIVES
To assess the beneficial and harmful effects of carvedilol compared with traditional, non-selective beta-blockers for adults with cirrhosis and gastroesophageal varices.
SEARCH METHODS
We combined searches in the Cochrane Hepato-Biliary's Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, LILACS, and Science Citation Index with manual searches. The last search update was 08 May 2018.
SELECTION CRITERIA
We included randomised clinical trials comparing carvedilol versus traditional, non-selective beta-blockers, irrespective of publication status, blinding, or language. We included trials evaluating both primary and secondary prevention of upper gastrointestinal bleeding in adults with cirrhosis and verified gastroesophageal varices.
DATA COLLECTION AND ANALYSIS
Three review authors (AZ, RJ and LH), independently extracted data. The primary outcome measures were mortality, upper gastrointestinal bleeding and serious adverse events. We undertook meta-analyses and presented results using risk ratios (RR) or mean differences (MD), both with 95% confidence intervals (CIs), and I values as a marker of heterogeneity. We assessed bias control using the Cochrane Hepato-Biliary domains and the quality of the evidence with GRADE.
MAIN RESULTS
Eleven trials fulfilled our inclusion criteria. One trial did not report clinical outcomes. We included the remaining 10 randomised clinical trials, involving 810 participants with cirrhosis and oesophageal varices, in our analyses. The intervention comparisons were carvedilol versus propranolol (nine trials), or nadolol (one trial). Six trials were of short duration (mean 6 (range 1 to 12) weeks), while four were of longer duration (13.5 (6 to 30) months). Three trials evaluated primary prevention; three evaluated secondary prevention; while four evaluated both primary and secondary prevention. We classified all trials as at 'high risk of bias'. We gathered mortality data from seven trials involving 507 participants; no events occurred in four of these. Sixteen of 254 participants receiving carvedilol and 19 of 253 participants receiving propranolol or nadolol died (RR 0.86, 95% CI 0.48 to 1.53; I = 0%, low-quality evidence). There appeared to be no differences between carvedilol versus traditional, non-selective beta-blockers and the risks of upper gastrointestinal bleeding (RR 0.77, 95% CI 0.43 to 1.37; 810 participants; 10 trials; I = 45%, very low-quality evidence) and serious adverse events (RR 0.97, 95% CI 0.67 to 1.42; 810 participants; 10 trials; I = 14%, low-quality evidence). Significantly more deaths, episodes of upper gastrointestinal bleeding and serious adverse events occurred in the long-term trials but there was not enough information to determine whether there were differences between carvedilol and traditional, non-selective beta-blockers, by trial duration. There was also insufficient information to detect differences in the effects of these interventions in trials evaluating primary or secondary prevention. There appeared to be no differences in the risk of non-serious adverse events between carvedilol versus its comparators (RR 0.55, 95% CI 0.23 to 1.29; 596 participants; 6 trials; I = 88%; very low-quality evidence). Use of carvedilol was associated with a greater reduction in hepatic venous pressure gradient than traditional, non-selective beta-blockers both in absolute (MD -1.75 mmHg, 95% CI -2.60 to -0.89; 368 participants; 6 trials; I = 0%; low-quality evidence) and percentage terms (MD -8.02%, 95% CI -11.49% to -4.55%; 368 participants; 6 trials; I = 0%; low-quality evidence). However, we did not observe a concomitant reduction in the number of participants who failed to achieve a sufficient haemodynamic response (RR 0.76, 95% CI 0.57 to 1.02; 368 participants; 6 trials; I = 42%; very low-quality evidence) or in clinical outcomes.
AUTHORS' CONCLUSIONS
We found no clear beneficial or harmful effects of carvedilol versus traditional, non-selective beta-blockers on mortality, upper gastrointestinal bleeding, serious or non-serious adverse events despite the fact that carvedilol was more effective at reducing the hepatic venous pressure gradient. However, the evidence was of low or very low quality, and hence the findings are uncertain. Additional evidence is required from adequately powered, long-term, double-blind, randomised clinical trials, which evaluate both clinical and haemodynamic outcomes.

Meta-Analysis Review
BACKGROUND AND AIM
Ursodeoxycholic acid (UDCA) is the standard treatment for primary biliary cirrhosis (PBC), but not all cases respond well. Evidence has shown that combination therapy of UDCA with bezafibrate significantly improved liver function. A meta-analysis was performed to assess the efficacy and safety of UDCA and bezafibrate combination therapy in the treatment of PBC.
RESULTS
Nine trials, with a total of 269 patients, were included in the analysis. The bias risk of these trials was high. Compared with UDCA alone, the combination with bezafibrate improved the Mayo risk score (mean difference [MD], 0.60; 95% confidence interval [CI], 0.25-0.95; P=0.0008) and liver biochemistry: alkaline phosphatase (MD, -238.21 IU/L; 95% CI, -280.83 to -195.60; P<0.00001); gamma-glutamyltransferase (MD, -38.23 IU/L; 95% CI, -50.16 to -25.85; P<0.00001); immunoglobulin M (MD, -128.63 IU/L; 95% CI, -151.55 to -105.71; P<0.00001); bilirubin (MD, -0.20 mg/dL; 95% CI, -0.33 to -0.07; P=0.002); triglycerides (MD, -26.84 mg/dL; 95% CI, -36.51 to -17.17; P<0.0001); total cholesterol (MD, -21.58 mg/dL; 95% CI, -30.81 to -12.34; P<0.0001), and serum alanine aminotransferase (MD, -10.24 IU/L; 95% CI, -12.65 to -78.5; P<0.00001). However, combination therapy showed no significant differences in the incidence of all-cause mortality or pruritus, and may have resulted in more adverse events (risk ratio [RR], 0.22; 95% CI, 0.07-0.67; P=0.008).
CONCLUSION
Combination therapy improved liver biochemistry and the prognosis of PBC, but did not improve clinical symptoms or incidence of death. Attention should be paid to adverse events when using bezafibrate.

Meta-Analysis Review
BACKGROUND & AIMS
Nonalcoholic fatty liver disease (NAFLD) may be a risk factor for hepatocellular carcinoma (HCC), but the extent of this association still needs to be addressed. Pooled incidence rates of HCC across the disease spectrum of NAFLD have never been estimated by meta-analysis.
METHODS
In this systematic review, we searched Web of Science, Embase, PubMed, and the Cochrane Library from January 1, 1950 through July 30, 2020. We included studies reporting on HCC incidence in patients with NAFLD. The main outcomes were pooled HCC incidences in patients with NAFLD at distinct severity stages. Summary estimates were calculated with random-effects models. Sensitivity analyses and meta-regression analyses were carried out to address heterogeneity.
RESULTS
We included 18 studies involving 470,404 patients. In patients with NAFLD at a stage earlier than cirrhosis, the incidence rate of HCC was 0.03 per 100 person-years (95% confidence interval [CI], 0.01-0.07; I = 98%). In patients with cirrhosis, the incidence rate was 3.78 per 100 person-years (95% CI, 2.47-5.78; I = 93%). Patients with cirrhosis undergoing regular screening for HCC had an incidence rate of 4.62 per 100 person-years (95% CI, 2.77-7.72; I = 77%).
CONCLUSIONS
Patients with NAFLD-related cirrhosis have a risk of developing HCC similar to that reported for patients with cirrhosis from other etiologies. Evidence documenting the risk in patients with nonalcoholic steatohepatitis or simple steatosis is limited, but the incidence of HCC in these populations may lie below thresholds used to recommend a screening. Well-designed prospective studies in these subpopulations are needed. The protocol for this systematic review is registered in the Prospero database (registration number CRD42018092861).

Meta-Analysis
BACKGROUND
Antibiotic prophylaxis seems to decrease the incidence of bacterial infections in patients with cirrhosis and upper gastrointestinal bleeding and is considered standard of care. However, there is no updated information regarding the effects of this intervention.
AIM
To assess the benefits and harms of antibiotic prophylaxis in cirrhotic patients with gastrointestinal bleeding by performing a systematic review of randomised trials.
METHODS
We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials in The Cochrane Library, MEDLINE, EMBASE and Science Citation Index EXPANDED until June 2010. We statistically combined data calculating relative risk (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes.
RESULTS
Twelve trials (1241 patients) evaluating antibiotic prophylaxis against placebo or no antibiotic prophylaxis were included. Antibiotic prophylaxis was associated with reduced mortality (RR 0.79, 95% CI 0.63-0.98), mortality from bacterial infections (RR 0.43, 95% CI 0.19-0.97), bacterial infections (RR 0.35, 95% CI 0.26-0.47), rebleeding (RR 0.53, 95% CI 0.38-0.74) and days of hospitalisation (MD -1.91, 95% CI -3.80-0.02). Trials analysing rebleeding rate and hospitalisation length are still scarce, thus, caution should be exerted when interpreting the results.
CONCLUSIONS
Antibiotic prophylaxis in patients with cirrhosis and upper gastrointestinal bleeding significantly reduced bacterial infections, and reduce all-cause mortality, bacterial infection mortality, rebleeding events and hospitalisation length. Novel clinically significant outcomes were included in this meta-analysis. Some benefits are biased and the risks are not yet properly assessed, this encourages future research in this field.

Review
OBJECTIVE
Studies on the epidemiology of primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) show variable outcome. We aimed at systematically reviewing the incidence and prevalence rates, as well as geographical distribution and temporal trends of PSC and PBC.
DATA SOURCES
A systematic search of literature was performed in Medline and EMBASE (search last conducted January 10th, 2011).
STUDY SELECTION
Population-based epidemiological studies reporting incidence and/or prevalence rates for PSC or PBC in a defined geographical area of at least 100,000 adult inhabitants were considered relevant.
DATA EXTRACTION
Study area, study period, number of patients, number of inhabitants, incidence per 100,000 inhabitants per year, prevalence per 100,000 inhabitants, method of case-finding, method of case-ascertainment, male/female ratio and in case of PSC, occurrence of inflammatory bowel diseases (IBD) were extracted from retrieved articles.
RESULTS
The literature search yielded 2286 abstracts of which 31 articles fulfilled all inclusion criteria. Studies varied in size from 10 to 770 patients in catchment areas from 100,312 to 19,230,000 inhabitants. The incidence and prevalence rates for PSC range from 0 to 1.3 per 100,000 inhabitants/year and 0-16.2 per 100,000 inhabitants, respectively. PBC incidence rates range from 0.33 to 5.8 per 100,000 inhabitants/year and prevalence rates range from 1.91 to 40.2 per 100,000 inhabitants; prevalence rates are increasing in time.
CONCLUSIONS
Incidence and prevalence rates of both PSC and PBC vary widely and seem to be increasing. True population-based studies are scarce and therefore large population-based studies combining meticulous case-finding and case-ascertainment strategies are necessary.

Meta-Analysis Review
OBJECTIVE
Most comprehensive treatments for PBC include UDCA, combination of methotrexate (MTX), corticosteroids (COT), colchicine (COC) or bezafibrate (BEF), cyclosporin A (CYP), D-penicillamine (DPM), methotrexate (MTX), or azathioprine (AZP). Since the optimum treatment regimen remains inconclusive, we aimed to compare these therapies in terms of patient mortality or liver transplantation (MOLT) and adverse event (AE).
METHODS
We searched PubMed, Embase, Scopus and the Cochrane Library for randomized controlled trials until August 2014. We estimated HRs for MOLT and ORs for AE. The sensitivity analysis based on dose of UDCA was also performed.
RESULTS
The search identified 49 studies involving 12 different treatment regimens and 4182 patients. Although no statistical significance can be found in MOLT, COT plus UDCA was ranked highest for efficacy outcome amongst all the treatment regimes. While for AEs, compared with OBS or UDCA, monotherapy with COC (OR 5.6, P < 0.001; OR 5.89, P < 0.001), CYP (OR 3.24, P < 0.001; OR 3.42, P < 0.001), DPM (OR 8.00, P < 0.001; OR 8.45, P < 0.001) and MTX (OR 5.31, P < 0.001; OR 5.61, P < 0.001) were associated with statistically significant increased risk of AEs. No significant differences were found for other combination regimes. Effect estimates from indirect comparisons matched closely to estimates derived from pairwise comparisons. Consistently, in the sensitivity analysis, results closely resembled our primary analysis.
CONCLUSIONS
COT plus UDCA was the most efficacious among treatment regimens both for MOLT and AEs.
