Predictive factors for decompensating events in patients with cirrhosis with primary biliary cholangitis under different lines of therapy.

BACKGROUND AND AIMS: The landscape in primary biliary cholangitis (PBC) has changed with the advent of second-line treatments. However, the use of obeticholic acid (OCA) and fibrates in PBC-related cirrhosis is challenging. We assessed the impact of receiving a second-line therapy as a risk factor for decompensated cirrhosis in a real-world population with cirrhosis and PBC, and identify the predictive factors for decompensated cirrhosis in these patients. APPROACH AND RESULTS: Multicenter study enrolling 388 patients with PBC-cirrhosis from the Spanish ColHai registry. Biopsy (20%), ultrasound (59%), or transient elastography (21%) defined cirrhosis, and the presence of varices and splenomegaly defined clinically significant portal hypertension (CSPH). Paris-II and PBC OCA international study of efficacy criteria determined the response to ursodeoxycholic acid (UDCA), fibrates (n=93), and OCA (n=104). The incidence of decompensated cirrhosis decreased for UDCA versus OCA or fibrates in the real-world population, but they were similar considering the propensity score-matched cohort (UDCA 3.77 vs. second-line therapy 4.5 100 persons-year, respectively), as patients on second-line therapy exhibited advanced liver disease. Consequently, GGT, albumin, platelets, clinically significant portal hypertension, and UDCA response were associated with a decompensating event. OCA response (achieved in 52% of patients) was associated with bilirubin (OR 0.21 [95% CI: 0.06-0.73]) and AST (OR 0.97 [95% CI: 0.95-0.99]), while fibrate response (achieved in 55% of patients) with AST [OR 0.96 (95% CI: 0.95-0.98]). In patients treated with OCA, drug response (sHR 0.23 [95% CI: 0.08-0.64]), diabetes (sHR 5.62 [95% CI: 2.02-15.68]), albumin (sHR 0.34 [95% CI: 0.13-0.89]), and platelets (sHR 0.99 [95% CI: 0.98-1.00]) were related to decompensation. In patients treated with fibrate, drug response (sHR 0.36 (95% CI: 0.14-0.95]), albumin (sHR 0.36 (95% CI: 0.16-0.81]), and clinically significant portal hypertension (sHR 3.70 (95% CI: 1.17-11.70]) were associated with decompensated cirrhosis. CONCLUSIONS: Advanced PBC, rather than OCA and fibrates, was found to be associated with decompensating events. Therefore, biochemical and clinical variables should be considered when making decisions about the management of these drugs. Moreover, a positive response to OCA and fibrates reduced the risk of decompensation.

Further decompensation in cirrhosis: Results of a large multicenter cohort study supporting Baveno VII statements.

BACKGROUND AND AIMS: The prognostic weight of further decompensation in cirrhosis is still unclear. We investigated the incidence of further decompensation and its effect on mortality in patients with cirrhosis. APPROACH AND RESULTS: Multicenter cohort study. The cumulative incidence of further decompensation (development of a second event or complication of a decompensating event) was assessed using competing risks analysis in 2028 patients. A 4-state model was built: first decompensation, further decompensation, liver transplant, and death. A cause-specific Cox model was used to assess the adjusted effect of further decompensation on mortality. Sensitivity analyses were performed for patients included before or after 1999. In a mean follow-up of 43 months, 1192 patients developed further decompensation and 649 died. Corresponding 5-year cumulative incidences were 52% and 35%, respectively. The cumulative incidences of death and liver transplant after further decompensation were 55% and 9.7%, respectively. The most common further decompensating event was ascites/complications of ascites. Five-year probabilities of state occupation were 24% alive with first decompensation, 21% alive with further decompensation, 7% alive with a liver transplant, 16% dead after first decompensation without further decompensation, 31% dead after further decompensation, and <1% dead after liver transplant. The HR for death after further decompensation, adjusted for known prognostic indicators, was 1.46 (95% CI: 1.23-1.71) ( p <0.001). The significant impact of further decompensation on survival was confirmed in patients included before or after 1999. CONCLUSIONS: In cirrhosis, further decompensation occurs in ~60% of patients, significantly increases mortality, and should be considered a more advanced stage of decompensated cirrhosis.

Development, validation, and prognostic evaluation of a risk score for long-term liver-related outcomes in the general population: a multicohort study.

BACKGROUND: Liver cirrhosis is a major cause of death worldwide. Cirrhosis develops after a long asymptomatic period of fibrosis progression, with the diagnosis frequently occurring late, when major complications or cancer develop. Few reliable tools exist for timely identification of individuals at risk of cirrhosis to allow for early intervention. We aimed to develop a novel score to identify individuals at risk for future liver-related outcomes. METHODS: We derived the LiverRisk score from an international prospective cohort of individuals from six countries without known liver disease from the general population, who underwent liver fibrosis assessment by transient elastography. The score included age, sex, and six standard laboratory variables. We created four groups: minimal risk, low risk, medium risk, and high risk according to selected cutoff values of the LiverRisk score (6, 10, and 15). The model's discriminatory accuracy and calibration were externally validated in two prospective cohorts from the general population. Moreover, we ascertained the prognostic value of the score in the prediction of liver-related outcomes in participants without known liver disease with median follow-up of 12 years (UK Biobank cohort). FINDINGS: We included 14 726 participants: 6357 (43·2%) in the derivation cohort, 4370 (29·7%) in the first external validation cohort, and 3999 (27·2%) in the second external validation cohort. The score accurately predicted liver stiffness in the development and external validation cohorts, and was superior to conventional serum biomarkers of fibrosis, as measured by area under the receiver-operating characteristics curve (AUC; 0·83 [95% CI [0·78-0·89]) versus the fibrosis-4 index (FIB-4; 0·68 [0·61-0·75] at 10 kPa). The score was effective in identifying individuals at risk of liver-related mortality, liver-related hospitalisation, and liver cancer, thereby allowing stratification to different risk groups for liver-related outcomes. The hazard ratio for liver-related mortality in the high-risk group was 471 (95% CI 347-641) compared with the minimal risk group, and the overall AUC of the score in predicting 10-year liver-related mortality was 0·90 (0·88-0·91) versus 0.84 (0·82-0·86) for FIB-4. INTERPRETATION: The LiverRisk score, based on simple parameters, predicted liver fibrosis and future development of liver-related outcomes in the general population. The score might allow for stratification of individuals according to liver risk and thus guide preventive care.

Budesonide as first-line treatment in patients with autoimmune hepatitis seems inferior to standard predniso(lo)ne administration.

BACKGROUND AND AIMS: In patients with non-severe acute or chronic autoimmune hepatitis (AIH) without cirrhosis, clinical practice guidelines recommend indistinct use of prednisone or budesonide. However, budesonide is infrequently used in clinical practice. We aimed to describe its use and compare its efficacy and safety with prednisone as first-line options. APPROACH AND RESULTS: This was a retrospective, multicenter study of 105 naive AIH patients treated with budesonide as the first-line drug. The control group included 276 patients treated with prednisone. Efficacy was assessed using logistic regression and validated using inverse probability of treatment weighting propensity score. The median time to biochemical response (BR) was 3.1 months in patients treated with budesonide and 4.9 months in those with prednisone. The BR rate was significantly higher in patients treated with prednisone (87% vs. 49% of patients with budesonide, p < 0.001). The probability of achieving BR, assessed using the inverse probability of treatment weighting propensity score, was significantly lower in the budesonide group (OR = 0.20; 95% CI: 0.11-0.38) at any time during follow-up, and at 6 (OR = 0.51; 95% CI: 0.29-0.89) and 12 months after starting treatment (0.41; 95% CI: 0.23-0.73). In patients with transaminases <2 × upper limit of normal, BR was similar in both treatment groups. Prednisone treatment was significantly associated with a higher risk of adverse events (24.2% vs. 15.9%, p = 0.047). CONCLUSIONS: In the real-life setting, the use of budesonide as first-line treatment is low, and it is generally prescribed to patients with perceived less disease activity. Budesonide was inferior to prednisone as a first-line drug but was associated with fewer side effects.

Population screening for liver fibrosis: Toward early diagnosis and intervention for chronic liver diseases.

Cirrhosis, highly prevalent worldwide, develops after years of hepatic inflammation triggering progressive fibrosis. Currently, the main etiologies of cirrhosis are non-alcoholic fatty liver disease and alcohol-related liver disease, although chronic hepatitis B and C infections are still major etiological factors in some areas of the world. Recent studies have shown that liver fibrosis can be assessed with relatively high accuracy noninvasively by serological tests, transient elastography, and radiological methods. These modalities may be utilized for screening for liver fibrosis in at-risk populations. Thus far, a limited number of population-based studies using noninvasive tests in different areas of the world indicate that a significant percentage of subjects without known liver disease (around 5% in general populations and a higher rate -18% to 27%-in populations with risk factors for liver disease) have significant undetected liver fibrosis or established cirrhosis. Larger international studies are required to show the harms and benefits before concluding that screening for liver fibrosis should be applied to populations at risk for chronic liver diseases. Screening for liver fibrosis has the potential for changing the current approach from diagnosing chronic liver diseases late when patients have already developed complications of cirrhosis to diagnosing liver fibrosis in asymptomatic subjects providing the opportunity of preventing disease progression.

Tenofovir Disoproxil Fumarate Reduces the Severity of COVID-19 in Patients with Chronic Hepatitis B.

BACKGROUND AND AIMS: HIV-positive patients on tenofovir hydroxyl fumarate (TDF)/emtricitabine have a lower risk of COVID-19 and hospitalization than those given other treatments. Our aim was to analyze the severity of COVID-19 in patients with chronic hepatitis B (CHB) on TDF or entecavir (ETV). METHODS: Spanish hospital databases (n = 28) including information regarding adult CHB patients on TDF or ETV for the period February 1st to November 30th 2020 were searched for COVID-19, defined as a positive SARS-CoV-2 polymerase chain reaction, and for severe COVID-19. RESULTS: Of 4736 patients, 117 had COVID-19 (2.5%), 67 on TDF and 50 on ETV. Compared to patients on TDF, those on ETV showed (p < 0.05) greater rates of obesity, diabetes, ischemic cardiopathy, and hypertension. COVID-19 incidence was similar in both groups (2.3 vs. 2.6%). Compared to TDF, patients on ETV more often (p < 0.01) had severe COVID-19 (36 vs. 6%), required intensive care unit (ICU) (10% vs. 0) or ventilatory support (20 vs. 3%), were hospitalized for longer (10.8 ± 19 vs. 3.1 ± 7 days) or died (10 vs. 1.5%, p = 0.08). In an IPTW propensity score analysis adjusted for age, sex, obesity, comorbidities, and fibrosis stage, TDF was associated with a sixfold reduction in severe COVID-19 risk (adjusted-IPTW-OR 0.17, 95%CI 0.04-0.67, p = 0.01). CONCLUSION: Compared to ETV, TDF seems to play a protective role in CHB patients with SARS-CoV-2 whereby the risk of severe COVID-19 is lowered.

Follow-up evaluation of patients with liver test abnormalities detected during SARS-CoV2 infection.

Abnormal liver function tests (A-LFTs) during admission for coronavirus disease-19 (COVID-19) are frequent, but its evolution after COVID-19 resolution remains unexplored. We evaluated factors related to A-LFTs during COVID-19 and assessed the liver outcome after patients' discharge. This is a observational study including: (1) retrospective analysis of variables related to A-LFTs during COVID-19; and (2) follow-up evaluation with blood test, transient elastography and liver biopsy in those with persistent A-LFTs. A-LFTs were defined according to CTCAEv4.0. Among 595 patients, 366 (61.5%) showed A-LFTs. The ratio of partial pressure of oxygen and inspired oxygen fraction (P/F) below 200, ferritin ≥1000 ng/mL, male gender and antibiotic and immunomodulatory treatments were related to A-LFTs. Follow-up evaluation was performed in 153 individuals. Persistent A-LFTs at follow-up was similar in patients with/without A-LFTs during admission (14.1% vs. 4.9%, p = 0.104). Fifteen (93%) and 58 (39%) patients with/without A-LFTs at follow-up showed metabolic fatty liver disease criteria (p < 0.001), which were histologically confirmed. In conclusion, A-LFTs during COVID-19 were related to infection severity. Abnormalities remitted at follow-up in >80% of patients, and no correlation between A-LFTs at admission and at follow-up was found. Most patients with A-LFTs at follow-up had non-invasive and histologically proven fatty liver disease.

Effect of rifaximin on infections, acute-on-chronic liver failure and mortality in alcoholic hepatitis: A pilot study (RIFA-AH).

BACKGROUND & AIMS: Alcoholic hepatitis (AH) is associated with a high incidence of infection and mortality. Rifaximin reduces bacterial overgrowth and translocation. We aimed to study whether the administration of rifaximin as an adjuvant treatment to corticosteroids decreases the number of bacterial infections at 90 days in patients with severe AH compared to a control cohort. METHODS: This was a multicentre, open, comparative pilot study of the addition of rifaximin (1200 mg/day/90 days) to the standard treatment for severe AH. The results were compared with a carefully matched historical cohort of patients treated with standard therapy and matching by age and model of end-stage liver disease (MELD). We evaluated bacterial infections, liver-related complications, mortality and liver function tests after 90 days. RESULTS: Twenty-one and 42 patients were included in the rifaximin and control groups respectively. No significant baseline differences were found between groups. The mean number of infections per patient was 0.29 and 0.62 in the rifaximin and control groups, respectively (p = .049), with a lower incidence of acute-on-chronic liver failure (ACLF) linked to infections within the treatment group. Liver-related complications were lower within the rifaximin group (0.43 vs. 1.26 complications/patient respectively) (p = .01). Mortality was lower in the treated versus the control groups (14.2% vs. 30.9, p = .15) without significant differences. No serious adverse events were associated with rifaximin treatment. CONCLUSIONS: Rifaximin is safe in severe AH with a significant reduction in clinical complications. A lower number of infections and a trend towards a lower ACLF and mortality favours its use in these patients.

LiverScreen project: study protocol for screening for liver fibrosis in the general population in European countries.

BACKGROUND: The development of liver cirrhosis is usually an asymptomatic process until late stages when complications occur. The potential reversibility of the disease is dependent on early diagnosis of liver fibrosis and timely targeted treatment. Recently, the use of non-invasive tools has been suggested for screening of liver fibrosis, especially in subjects with risk factors for chronic liver disease. Nevertheless, large population-based studies with cost-effectiveness analyses are still lacking to support the widespread use of such tools. The aim of this study is to investigate whether non-invasive liver stiffness measurement in the general population is useful to identify subjects with asymptomatic, advanced chronic liver disease. METHODS: This study aims to include 30,000 subjects from eight European countries. Subjects from the general population aged ≥ 40 years without known liver disease will be invited to participate in the study either through phone calls/letters or through their primary care center. In the first study visit, subjects will undergo bloodwork as well as hepatic fat quantification and liver stiffness measurement (LSM) by vibration-controlled transient elastography. If LSM is ≥ 8 kPa and/or if ALT levels are ≥1.5 x upper limit of normal, subjects will be referred to hospital for further evaluation and consideration of liver biopsy. The primary outcome is the percentage of subjects with LSM ≥ 8kPa. In addition, a health economic evaluation will be performed to assess the cost-effectiveness and budget impact of such an intervention. The project is funded by the European Commission H2020 program. DISCUSSION: This study comes at an especially important time, as the burden of chronic liver diseases is expected to increase in the coming years. There is consequently an urgent need to change our current approach, from diagnosing the disease late when the impact of interventions may be limited to diagnosing the disease earlier, when the patient is asymptomatic and free of complications, and the disease potentially reversible. Ultimately, the LiverScreen study will serve as a basis from which diagnostic pathways can be developed and adapted to the specific socio-economic and healthcare conditions in each country. TRIAL REGISTRATION: This study is registered on Clinicaltrials.gov ( NCT03789825 ).

Presentation and Outcomes of Pregnancy in Patients With Autoimmune Hepatitis.

Autoimmune hepatitis (AIH) frequently affects women of childbearing age in whom the desire to have a family raises the question regarding the potential risks for the fetus and the mother. The information on AIH in pregnant patients is scarce.1 The aims of this study were (1) to identify the risk factors associated with flares in pregnant patients diagnosed with AIH, (2) to determine the course of AIH in patients with pregnancy-related flares, and (3) to describe the outcome of AIH diagnosed in the postpartum period.

Impact of anthropometric features on the applicability and accuracy of FibroScan® (M and XL) in overweight/obese patients.

BACKGROUND AND AIM: Transient elastography is the reference method for liver stiffness measurement (LSM) in the general population, having lower applicability in obese patients. We evaluated the applicability and diagnostic accuracy of the M and XL probes in overweight/obese patients to establish the most appropriate approach. METHODS: From May 2013 to March 2015, we evaluated patients with a body mass index (BMI) ≥ 28 kg/m2 . We constructed an algorithm with variables independently related to unreliable LSM with the M probe. RESULTS: A total of 1084 patients were evaluated. M and XL probe applicability was 88.8% and 98%, respectively. Waist circumference (WC) (OR; 95% CI; P) (0.97; 0.94-0.99; P < 0.001) and skin-capsule distance (SCD) (0.83; 0.79-0.87; P < 0.001) were independently related to unreliable LSM (M probe). The SCD was > 25 mm in 5.5% of individuals with a BMI ≤ 35 kg/m2 and a WC ≤ 117 cm, with LSM (M probe) applicability rising to 94.3%. In contrast, 36.9% of patients with a BMI > 35 kg/m2 and/or a WC > 117 cm presented an SCD > 25 mm, with M probe applicability being 73.1%. The diagnostic accuracy (area under the receiver operator characteristic) using the M probe to identify significant steatosis (0.76), fibrosis (0.89), and cirrhosis (0.96) was very high in patients with a BMI ≤ 35 kg/m2 and a WC ≤ 117 cm. CONCLUSIONS: The applicability and accuracy of the FibroScan® M probe to identify fibrosis and steatosis was excellent in overweight and obesity grade I (BMI ≤ 35 kg/m2 ) with a WC ≤ 117 cm. The XL probe increased the applicability of transient elastography in obesity grade II-III (BMI > 35 kg/m2 ).

Association Between Severe Portal Hypertension and Risk of Liver Decompensation in Patients With Hepatitis C, Regardless of Response to Antiviral Therapy.

BACKGROUND & AIMS: Hepatic venous pressure gradient (HVPG) is associated with a risk of liver events in patients with chronic hepatitis C. Antiviral therapies that lead to a sustained virologic response (SVR) reduce portal pressure and prevent liver disease progression. However, it is not clear to what extent the progression of hepatitis C is modified once patients develop cirrhosis with severe portal hypertension (CSPH) (HVPG ≥ 10 mm Hg). We assessed the effects of HVPG and SVR on the risk of liver decompensation, hepatocellular carcinoma, and/or death in patients with hepatitis C-related cirrhosis. METHODS: We collected data from 100 patients with hepatitis C and compensated cirrhosis who underwent HVPG measurement 3 months or less before (baseline) and 24 weeks after therapy with pegylated interferon alfa-2a and ribavirin at 4 hospitals in Spain, from 2001 through 2009. SVR was defined as undetectable serum HCV RNA level 24 weeks after treatment ended. Clinical data were collected until death, liver transplantation, or December 2012 (median, 5 y; interquartile range, 1.4-7 y). RESULTS: Seventy-four patients had CSPH at baseline and 35% of patients achieved an SVR. During the follow-up period, 19 patients developed liver decompensation (ascites, variceal bleeding, or encephalopathy). The actuarial probability values for liver decompensation at 1, 5, and 7 years were 3%, 19% and 22%, respectively. The baseline level of HVPG, but not SVR, was associated independently with the risk of liver decompensation. CONCLUSIONS: Patients with CSPH, regardless of an SVR to therapy for hepatitis C, remain at risk for liver decompensation within the first 5 years after treatment; they should be monitored closely.

Drug-drug interactions of telaprevir and boceprevir in HCV-monoinfected and HIV/HCV-coinfected patients can modify the adherence.

BACKGROUND & AIMS: The first generation protease inhibitors, boceprevir (BOC) and telaprevir (TVR), are both CYP3A4 inhibitors, which predispose drug-drug interactions (DDIs). The aim of this study was to evaluate the prevalence of potential DDIs, the management of outpatient medication and its impact on adherence and efficacy to antiviral treatment in hepatitis C virus (HCV)-monoinfected and human immunodeficiency virus (HIV)/HCV-coinfected patients receiving BOC and TVR. METHODS: The usual medication starting with BOC or TVR was screened by the pharmacist of the multidisciplinary support programme (MSP) for potential DDIs. Recommendations were made to avoid significant DDIs, and changes in the baseline medication were recorded. Adherence to antiviral treatment was considered as 80/80/95% of total doses. Sustained virological response was assessed at week 12 (SVR12). RESULTS: At least one potential DDI was found in 70 (64.8%) patients, 45 (54.2%) being HCV-monoinfected and 25 (100%) HIV/HCV-coinfected (P < 0.01). Baseline treatment modifications were required in 38 (35.2%) patients. Adherence and SVR12 were higher in patients without DDIs (86.8%) and (67.6%) compared to those with DDIs (62.8%) (P = 0.021) and (47.2%) (P = 0.097) respectively. CONCLUSIONS: More than half of the patients were at risk of presenting DDIs, leading to changes in the baseline medication in one-third of the patients. Drug interactions are frequent in patients with lower adherence.

A multidisciplinary support programme increases the efficiency of pegylated interferon alfa-2a and ribavirin in hepatitis C.

BACKGROUND & AIMS: Adherence to antiviral treatment is important to achieve sustained virological response (SVR) in chronic hepatitis C (CHC). We evaluated the efficiency of a multidisciplinary support programme (MSP), based on published HIV treatment experience, to increase patient adherence and the efficacy of pegylated interferon alfa-2a and ribavirin in CHC. METHODS: 447 patients receiving antiviral treatment were distributed into 3 groups: control group (2003-2004, n=147), MSP group (2005-2006, n=131), and MSP-validation group (2007-2009, n=169). The MSP group included two hepatologists, two nurses, one pharmacist, one psychologist, one administrative assistant, and one psychiatrist. Cost-effectiveness analysis was performed using a Markov model. RESULTS: Adherence and SVR rates were higher in the MSP (94.6% and 77.1%) and MSP-validation (91.7% and 74.6%) groups compared to controls (78.9% and 61.9%) (p<0.05 in all cases). SVR was higher in genotypes 1 or 4 followed by the MSP group vs. controls (67.7% vs. 48.9%, p=0.02) compared with genotypes 2 or 3 (87.7% vs. 81.4%, p=n.s.). The MSP was the main predictive factor of SVR in patients with genotype 1. The rate of adherence in patients with psychiatric disorders was higher in the MSP groups (n=95, 90.5%) compared to controls (n=28, 75.7%) (p=0.02). The cost per patient was € 13,319 in the MSP group and € 16,184 in the control group. The MSP group achieved more quality-adjusted life years (QALYs) (16.317 QALYs) than controls (15.814 QALYs) and was dominant in all genotypes. CONCLUSIONS: MSP improves patient compliance and increases the efficiency of antiviral treatment in CHC, being cost-effective.

Development and implementation of a continuing medical education program on non-alcoholic fatty liver disease for primary care practitioners in Europe.

Background: Primary care has a crucial role to play in the prevention, early detection, referral, and risk factor management of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NAFLD/NASH). In 2021, a team of European collaborators developed a continuing medical education (CME) program on NAFLD/NASH that consolidates evidence and clinical best practices tailored to the primary care setting. This article reports on the methodology used to design and develop the CME and the results of a feasibility study. Methods: An expert advisory group representing both European specialists and general practitioners supported the design of the CME to be implemented in three European settings (Greece, Spain, and Netherlands). The CME features four training modules and problem-based learning using clinical case studies. The CME was tested regarding feasibility and acceptability among a sample of primary care providers (PCPs) in Greece (n = 28) with measurements occurring before, immediately after, and 1 month following the training. Outcome measures included satisfaction with the CME, changes in PCPs' knowledge, attitudes, confidence, and self-reported clinical practices related to NAFLD/NASH. Results: The CME is available as an open-access e-learning course on the European Society for Primary Care Gastroenterology education platform in English, Greek, Spanish, and Dutch. The feasibility study documented high levels of satisfaction, with 96% of PCPs reporting they were extremely or very satisfied with the overall training. Statistically significant increases in PCPs' confidence in NAFLD/NASH-related clinical practices were documented between the pre- and post-assessments. At the follow-up, 62% of GPs reported that the CME had changed their clinical practices related to NAFLD/NASH to a great extent. Conclusion: This CME intervention developed by experts and tailored to PCPs in European settings may serve as an asset for increasing knowledge, confidence, and practice behaviors related to NAFLD/NASH.

Prevalence and characteristics of hepatitis C virus-related hepatocellular carcinoma in a Spanish university hospital.

BACKGROUND: Hepatocellular Carcinoma (HCC) arises in chronic liver diseases, particularly caused by hepatitis C virus (HCV) and alcohol in Europe. We aimed at evaluating the characteristics and mortality of patients with HCV-related HCC as compared to other HCC etiologies. METHODS: We retrospectively evaluated data from 887 patients with HCC identified through the Hospital del Mar Cancer Registry (Barcelona, Spain), during the 2001-2020 period. We estimated crude and adjusted hazard ratios (aHR) of dying and its 95% confidence interval (95%CI). RESULTS: Among 887 patients with HCC, 617 (69.6%) were HCV-infected. Underlying cirrhosis was more frequent in HCV-related HCC compared to other etiologies (97% vs. 89%, p < 0.001). The prevalence of HCV-related HCC decreased from 79% in 2001-2005 to 55% in 2015-2020 (p < 0.001). HCV infection did not increase the hazard of death [aHR 0.95 (CI95% 0.81-1.13)]. Mortality was independently related to age > 75 years, advanced BCLC stage at diagnosis, and diagnosis before 2010. CONCLUSION: In our cohort, HCV-related HCC frequently occurred in a cirrhotic background, but showed similar clinical characteristics and mortality as compared to other HCC etiologies.

On-therapy HBsAg kinetics can predict HBsAg loss after nucleos(t)ide analogues interruption in HBeAg-negative patients. The cup is half full and half empty.

BACKGROUND: Nucleos(t)ide analogues withdrawal may improve HBsAg loss rates. However, conditions to select patients are not well established. AIMS: to evaluate the impact of HBsAg kinetics before treatment interruption on post-treatment response. METHODS: Longitudinal, ambispective study in non-cirrhotic chronic hepatitis B HBeAg-negative patients, analysing on-treatment and post-treatment HBsAg kinetics. On-treatment HBsAg kinetics diagnostic accuracy (AUROC) to identify HBsAg loss was evaluated. RESULTS: 52 HBeAg-negative patients stopped treatment after 8.2 years, and 6 (11.5%) achieved HBsAg loss one year after withdrawal. Multivariate analysis showed that on-treatment HBsAg kinetics was related to HBsAg loss (OR=0.10; 95%CI=0.016-0.632; p = 0.014) with a high diagnostic accuracy (AUROC=0.935). A significant HBsAg decline ≥1 log10 IU/mL showed a positive and negative predictive value of 50% and of 97.6%, respectively. After treatment interruption, HBsAg decline speed (log10 IU/mL/year) accelerated in patients treated >6 years (from -0.06 to -0.20, p<0.05) and remained stable in treated <6 years (from -0.12 to -0.12 p=ns). CONCLUSIONS: On-treatment HBsAg kinetics can predict post-treatment HBsAg loss rate. Half of patients with a significant HBsAg decline can eliminate HBsAg the first year after withdrawal. Post-treatment HBsAg decline is faster not only in patients who lost the HBsAg but also in those who remain HBsAg-positive.

Worse outcome and distinct mutational pattern in follicular lymphoma with anti-HBc positivity.

Epidemiological studies have demonstrated the association between hepatitis B virus (HBV) infection and B-cell non-Hodgkin lymphoma (NHL), mainly for diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL). We studied a cohort of 121 patients with FL for HBV infection status, clinical features, and gene mutational profile. Anti-HBc was detectable in 16 patients (13.2%), although all had undetectable HBV DNA. Anti-HBcore+ (anti-HBc+) cases presented with older age at diagnosis than anti-HBc- cases (68.1 vs 57.2 years; P = .007) and higher ß2-microglobulin (56.3% vs 28.9%; P = .04). All patients included in the study fulfilled criteria for treatment and received therapy with rituximab or rituximab-containing chemotherapy. There were no episodes of HBV reactivation or HBV hepatitis during treatment and/or maintenance. Remarkably, anti-HBc+ patients had significantly lower 10-year progression-free survival (PFS; 12.9% vs 58.3%; P < .0001) and overall survival (OS; 22.0% vs 86.2%; P < .0001), that remained at multivariate analysis. Gene mutational profiling of all cases showed that anti-HBc+ cases had higher incidence of ARID1A mutations and absence of EP300 mutations, 2 key epigenetic regulators in FL. Overall, our study shows that FL patients with resolved HBV infection have a worse outcome independently of other well-known clinical risk factors and a distinct gene mutational profile.
