Elexacaftor/Tezacaftor/Ivacaftor use in Pediatric Cystic Fibrosis Patients with Advanced Liver Disease.

BACKGROUND: Cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy extends the life expectancy of people with cystic fibrosis (PwCF). However, CFTR modulators have not been well studied in patients with cystic fibrosis liver disease (CFLD), specifically those with advanced liver disease with portal hypertension. The purpose of this report is to describe the use of elexacaftor/tezacaftor/ivacaftor (ETI) in pediatric CF patients with advanced CFLD. METHODS: This retrospective case series included PwCF < 18 years old with baseline advanced CFLD initiated on ETI. RESULTS: Eleven PwCF and advanced CFLD were treated with ETI; six started a reduced dose regimen. No patient required treatment interruption and four patients received dose changes related to increase in transaminase and/or bilirubin elevations. Mean (SD) change in ppFEV1 from prior to ETI to highest value during therapy was 14.27 % (4.25) (p = 0.007). When evaluating the group as whole, AST decreased from baseline to last reported -15.18 (23.23) units/L (p = 0.054) and ALT slightly increased 0.73 (39.13) units/L (p = 0.96). Bilirubin increased minimally overall for patients with mean change from baseline of 0.83 (1.33) mg/dL [range -0.5-3] (p = 0.17). A model for time on ETI showed a significant decrease in AST over time of 0.955 per month of ETI but no other liver biochemistries were significant. No patient experienced decompensation of CFLD. CONCLUSION: ETI therapy in pediatric CF patients with advanced CFLD can be beneficial in improving pulmonary and nutritional outcomes without negative impact on liver biochemistries or hepatic outcomes. Close monitoring is recommended to ensure safety and tolerability.

Hepatofugal portal flow is highly predictive of acute-on-chronic liver failure: A new hemodynamic patho-physiological hypothesis.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is a severe complication of advanced liver disease. A significant number of ACLF patients have not clear precipitating factors. The aim of the study was to investigate the role of alterations in porto-hepatic hemodynamics, especially non-forward portal flow (NFPF), in ACLF and liver-related mortality. METHODS: 233 cirrhotic patients were included in the study with a median follow-up of 24 months. Color-Doppler ultrasound was used to assess portal vein patency, flow direction and significant porto-systemic collaterals (>8 mm). Patients with active cancer, both at baseline and during follow-up and severe non liver-related comorbidities were excluded. ACLF and liver-related mortality were recorded during follow-up. RESULTS: Fifty-six patients (24%) developed ACLF; 24 (10,3%) had baseline NFPF. In survival analysis, NFPF, but not portal vein thrombosis, was independently associated with ACLF development (HR 2.85 95% C.I. [1.49-5.42], p = 0.001) and liver-related mortality (HR 2.24 95% C.I. [1.16-4.28], p = 0.015), even after adjustment for liver disease severity scores, age and etiology of liver disease. CONCLUSION: NFPF is independently associated with ACLF development and liver-related mortality, regardless of etiology, severity disease scores and portal vein thrombosis. Although there is no specific measure to reverse NFPF, patients with NFPF should receive prompt intensive management and urgent prioritization for liver transplantation.

Introduction: Liver diseases are a prevalent problem worldwide. To date, liver biopsy has been the gold standard for assessing the degree of fibrosis; however, with the advent of new non-invasive, cost-effective methods for the healthcare system, we are resorting to it less and less. Shear wave elastography with biplanar imaging was recently introduced in our setting, which implies a learning curve for technicians. Objective: To assess the association of the degrees of liver fibrosis determined by shear wave elastography with biplanar imaging (2D-SWE) and the APRI score in patients with liver disease treated in the hepatology service of the Pasteur Hospital. Methodology: Patients with liver disease of any etiology, attended between 01/10/21 and 08/31/22, over 15 years of age, of both sexes and who have been evaluated with shear wave elastography with biplanar image were included. (2D-SWE) and blood analysis performed by the medical team of the aforementioned service in the last 6 months. Results: 158 patients were included. A higher prevalence of liver disease was found in women, with a predominance of the etiology of nonalcoholic fatty liver disease (NAFLD) and hepatitis C virus (HCV) infection. A positive association was evident between elastography (2D-SWE) and the APRI score for the diagnosis or exclusion of advanced liver disease, with no statistically significant difference between the two hepatologists. Conclusions: There is an association between SWE elastography and the APRI score for the diagnosis of advanced liver disease in the general population and by etiology.

Introdução: As doenças hepáticas são um problema prevalente em todo o mundo.

Conclusões: Existe associação entre a elastografia SWE e o escore APRI para o diagnóstico de doença hepática avançada na população geral e por etiologia.

Safety and Efficacy of Immune Checkpoint Inhibitors in Patients with Cancer and Viral Hepatitis: The MD Anderson Cancer Center Experience.

BACKGROUND: Despite the clinical benefit of immune checkpoint inhibitors (ICIs), patients with a viral hepatitis have been excluded from clinical trials because of safety concerns. The purpose of this study was to determine the incidence rate of adverse events (AEs) in patients with viral hepatitis who received ICIs for cancer treatment. MATERIALS AND METHODS: We conducted a retrospective study in patients with cancer and concurrent hepatitis B or C, who had undergone treatment with ICI at MD Anderson Cancer Center from January 1, 2010 to December 31, 2019. RESULTS: Of the 1076 patients screened, we identified 33 with concurrent hepatitis. All 10 patients with HBV underwent concomitant antiviral therapy during ICI treatment. Sixteen of the 23 patients with HCV received it before the initiation of ICI. The median follow-up time was 33 months (95% CI, 23-45) and the median duration of ICI therapy was 3 months (IQR, 1.9-6.6). Of the 33 patients, 12 (39%) experienced irAEs (immune-related adverse events) of any grade, with 2 (6%) having grade 3 or higher. None of the patients developed hepatitis toxicities. CONCLUSION: ICIs may be a therapeutic option with an acceptable safety profile in patients with cancer and advanced liver disease.

Magnitude and genotype of hepatitis delta virus among chronic hepatitis B carriers with a spectrum of liver diseases in Ethiopia.

INTRODUCTION AND OBJECTIVES: Chronic hepatitis D infection contributes substantially to the progression of chronic liver disease, especially in most low and middle-income countries, where hepatitis B virus-related chronic liver disease is endemic. Therefore, this study aimed to determine the magnitude and genotype of hepatitis delta virus (HDV) among patients with chronic hepatitis B (CHB)-related liver diseases in Ethiopia. PATIENTS AND METHODS: In this cross-sectional study, 323 known HBsAg positive individuals comprising 220 patients with CHB-related liver diseases [121 advanced liver diseases (hepatocellular carcinoma /HCC/ and non-HCC) and 99 chronic hepatitis (CH)], and 103 symptomless blood donors (BD) were enrolled. An ELISA kit was employed to determine HDV infection, and quantitative real-time PCR was used to detect HDV RNA. In addition, a non-coding genomic RNA region was sequenced for genotyping and phylogenetic analysis. RESULTS: Irrespective of the stage of liver disease, the overall magnitude of HDV was 7.7% (25/323). The frequency of anti-HDV increases with the severity of liver disease, 1.9%, 4%, 10%, and 21.3% among BD, CH, non-HCC, and HCC patients, respectively. HDV RNA has been detected in 1.54 %(5/323) cases with a mean viral load of 4,010,360 IU/ml. All isolates were found to be HDV genotype 1. CONCLUSIONS: The magnitude of HDV infection increased with the severity of liver disease, indicating HDV infection is more common among patients with CHB-related liver diseases in Ethiopia.

Bicyclol ameliorates advanced liver diseases in murine models via inhibiting the IL-6/STAT3 signaling pathway.

Bicyclol, a synthetic hepatoprotective and anti-inflammatory agent approved in China, was widely used to treat various hepatitis accompanied by elevated serum aminotransferases. However, the pharmacological effects and mechanisms of bicyclol on advanced liver diseases, such as fibrosis/cirrhosis and hepatocellular carcinoma (HCC), remain to be explored. Here, we revealed that bicyclol prevents from formatting severe fibrosis, slows the progression of moderate liver fibrosis, accelerates the regression of moderate liver fibrosis, decreases the malignancy of HCC in rat models induced by diethylnitrosamine (DEN), and also blocks steatohepatitis to HCC in mice induced by western diet plus carbon tetrachloride and DEN. The detailed pharmacological mechanism showed that bicyclol alleviates chronic progressive liver diseases by inhibiting the levels of IL-6 and subsequent phosphorylated STAT3. Conclusion: Bicyclol plays significant protective roles in multiply stages of fibrosis/cirrhosis-HCC and nonalcoholic fatty liver disease-related HCC via inhibiting IL-6/STAT3 signaling pathway. Therefore, bicyclol might be a promising therapeutic strategy for treating advanced liver diseases.

Co-infections, comorbidities, and alcohol or other substances abuses in chronic hepatitis C-related hospitalisations in Spain.

BACKGROUND: The Strategic Plan for Tackling Hepatitis C launched in 2015 in Spain has led to an important nationwide decrease in hepatitis C related hospitalisation rates. However, patients' infection progression during decades could increase their health status complexity and challenge patient's prognosis after hepatitis C eradication. METHODS: We carried out an observational retrospective study evaluating the prevalence of the main co-infections, comorbidities (risk factors and extrahepatic manifestations), and alcohol or other substances abuses in chronic hepatitis C related hospitalised patients in Spain. Data were obtained from the National Hospitalisation Registry discharges from January 1st of 2012 to December 31st of 2019. RESULTS: Between 2012 and 2019 there were 356,197 chronic hepatitis C-related hospitalisations. In-hospital deaths occurred in 11,558 (4.6%) non-advanced liver disease and in 10,873 (10.4%) advanced liver disease-related hospitalisations. Compared to 2012-2015, in 2016-2019 the proportion of hospitalisations related to non-advanced liver disease increased from 69.4% to 72.4%, while the advanced disease-related hospitalisations decreased from 30.6% to 27.6% (P<.001). In spite of the decrease in severe cases among hospitalisations, all comorbidities evaluated, and alcohol abuse increased in 2016-2019 compared to 2012-2015, while co-infections and other substances abuses decreased in the same period. In the latest period (2016-2019): 28,679 (18.3%) of the hospitalised patients had a HIV, 6928 (4.4%) a hepatitis B, and 972 (.6%) a tuberculosis co-infection. Most frequent comorbidities were diabetes (N=33,622; 21.5%); moderate to severe renal disease (N=28,042; 17.9%), chronic obstructive pulmonary disease and asthma (N=25,559; 16.3%), and malignant neoplasms (excluding hepatocellular carcinoma) (N=19,873; 12.7%). Alcohol or substances abuse was reported in 48,506 (31.0%) hospitalisations: 30,782 (19.7%) with alcohol; 29,388 (18.8%) with other substances; and 11,664 (7.5%) with both, alcohol and other substances, abuses. CONCLUSIONS: Despite the reduction in advanced liver disease hepatitis C-related hospitalisations due to prioritisation of treatment to the more severe cases, high and increasing prevalence of comorbidities and risks factors among hepatitis C-related hospitalisations have been found.

Liver cancer risk after HCV cure in patients with advanced liver disease without non-characterized nodules.

BACKGROUND & AIMS: Recognition of non-characterized liver nodules (NCLN) prior to direct-acting antivirals (DAAs) is associated with increased hepatocellular carcinoma (HCC) risk in patients with HCV. The risk of HCC has not been defined in F3/F4 patients in whom NCLN have been ruled-out before starting DAAs and at sustained virological response (SVR). This study aimed to estimate HCC incidence in this population. METHODS: We performed a prospective study including HCV-infected patients with F3/F4 fibrosis, without a history of HCC, and who achieved SVR after DAAs. Patients were only included if they had undergone ultrasound imaging that excluded the presence of HCC/NCLN within 30 days after SVR. All patients were evaluated every 6 months until developing primary liver cancer, death or withdrawal of informed consent. HCC incidence was expressed per 100 patient-years (/100PY). Adherence to screening program was calculated every 6 months for the first 48 months. RESULTS: A total of 185 patients (63/122, F3/F4) were included. Among those with cirrhosis, 92% were Child-Pugh A and 42.7% had clinically significant portal hypertension (CSPH). Albumin-bilirubin score was 1 in 84.9% and 2 in 15.1% of patients, respectively. The median clinical and radiologic follow-up was 52.4 months and 48 months, respectively. Ten patients developed HCC: HCC incidence was 1.46/100PY (95% CI 0.79-2.71) in the whole cohort, 2.24/100PY (95% CI 1.21-4.17) in F4 only and 3.63/100PY (95% CI 1.95-6.74) in patients with CSPH. No HCC was registered in patients with F3. Median time between SVR and HCC occurrence was 28.1 months; 12 non-primary liver cancers were also identified. CONCLUSIONS: Patients with cirrhosis without NCLN at SVR remain at risk of HCC development. The absence of HCC in patients with F3 reinforces their marginal cancer risk, but prospective studies are needed to exclude them from screening programs. LAY SUMMARY: Patients with HCV-related cirrhosis, without non-characterized liver nodules at sustained virologic response, remain at risk of hepatocellular carcinoma despite viral cure. However, the cancer risk after successful direct-acting antiviral treatment is marginal in patients with F3 fibrosis without non-characterized liver nodules. If confirmed in larger prospective studies, current screening recommendations may need to be revisited in this group of patients.

Prevalence and Clinical Significance of Occult Hepatitis B Infection in The Gambia, West Africa.

BACKGROUND: Prevalence and clinical outcomes of occult hepatitis B infection (OBI) have been poorly studied in Africa. METHODS: Using the PROLIFICA cohort, we compared the prevalence of OBI between hepatitis B surface antigen (HBsAg)-negative healthy adults screened from the general population (controls) and HBsAg-negative patients with advanced liver disease (cases), and estimated the population attributable fraction for the effect of OBI on advanced liver disease. RESULTS: OBI prevalence was significantly higher among cases (15/82, 18.3%) than controls (31/330, 9.4%, P = .03). After adjusting for age, sex, and anti-hepatitis C virus (HCV) serology, OBI was significantly associated with advanced liver disease (odds ratio, 2.8; 95% confidence interval [CI], 1.3-6.0; P = .006). In HBsAg-negative people, the proportions of advanced liver disease cases attributable to OBI and HCV were estimated at 12.9% (95% CI, 7.5%-18.1%) and 16.9% (95% CI, 15.2%-18.6%), respectively. CONCLUSIONS: OBI is endemic and an independent risk factor for advanced liver disease in The Gambia, West Africa. This implies that HBsAg-negative people with liver disease should be systematically screened for OBI. Moreover, the impact of infant hepatitis B immunization to prevent end-stage liver disease might be higher than previous estimates based solely on HBsAg positivity.

Incidence of liver-related morbidity and mortality in a population cohort of non-alcoholic fatty liver disease.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) increases morbidity and mortality. However, patients in biopsy-based cohorts are highly selected and the absolute risks of liver- and non-liver outcomes in NAFLD in population remains undefined. We analysed both liver-related and non-liver-related outcomes in Finnish population cohorts of NAFLD. METHODS: We included 10 993 individuals (6707 men, mean age 53.3 ± 12.6 years) with NAFLD (fatty liver index ≥60) from the Finnish population-based FINRISK and Health 2000 studies. Liver fibrosis was assessed by the dAAR score, and genetic risk by a recent polygenic risk score (PRS-5). Incident liver-related outcomes, cardiovascular disease (CVD), cancer and chronic kidney disease (CKD) were identified through linkage with national registries. RESULTS: Mean follow-up was 12.1 years (1128 069 person-years). The crude incidence rate of liver-related outcomes in NAFLD was 0.97/1000 person-years. The cumulative incidence increased with age, being respectively 2.4% and 1.5% at 20 years in men and women aged 60 years at baseline, while the relative risks for CVD and cancer were 9-16 times higher. The risk of CKD exceeded that of liver outcomes at a baseline age around 50 years. 20-year cumulative incidence of liver-related outcomes was 4.3% in the high, and 1.5% in the low PRS-5 group. The dAAR score associated with liver outcomes, but not with extra-hepatic outcomes. CONCLUSION: The absolute risk of liver-related outcomes in NAFLD is low, with much higher risk of CVD and cancer, emphasizing the need for more individualized and holistic risk-stratification in NAFLD.

Management of NAFLD patients with advanced fibrosis.

The prevalence of non alcoholic fatty liver disease (NAFLD) has increased to 25% in the general population and could double by 2030. Liver fibrosis is the main indicator of morbidity and mortality and recent estimations suggest a substantial number of individuals with undiagnosed advanced liver disease. Strategies to monitor advanced fibrosis are essential for early detection, referral, diagnosis and treatment in primary care and endocrine units, where NAFLD and consequently liver fibrosis are more prevalent. Blood-based non-invasive methods could be used to stratify patients according to the risk of the progression of fibrosis and combined with imaging techniques to improve stratification. Powerful new diagnostic tools such as MRE and PDFF are emerging and might prevent the need for liver biopsy in the near future. The current therapeutic landscape of NAFLD is rapidly evolving with an increasing number of molecules that treat key factors involved in its progression, but that still have a limited or no ability to effectively reverse fibrosis. Management of this disease will probably require a combination of sequential and personalized treatments as a result of its complex and dynamic pathophysiology. Lifestyle interventions are still the most effective therapeutic option and should be better integrated into patient management together with specific programs of bariatric endoscopy/surgery for morbidly obese patients.

Prevalence of COVID-19 in patients with autoimmune liver disease in Europe: A patient-oriented online survey.

BACKGROUND: During the current SARS-CoV-2 pandemic it is important to identify risk factors for COVID-19. Registry studies are providing growing evidence on the elevated risk of mortality from COVID-19 in patients with chronic liver disease, especially in advanced stages. Results may, however, have a selection bias towards severe cases. Limited data is available on COVID-19 in patients with autoimmune liver disease (AILD). AIM: To perform an online survey to capture the prevalence of COVID-19 and the state of medical care of patients with AILD in Europe during the pandemic. METHODS: Data was collected via an anonymous patient-oriented, online survey, which was available on the EUSurvey platform in nine European languages between 24th June 2020 and 14th October 2020. Of 1834 contributions, 51 were excluded because participants did not name an underlying AILD, and four were excluded because of duplicate data entry. RESULTS: Of 1,779 participants, 1,752 resided in 20 different countries of the European Union and the United Kingdom (UK). The five countries with the highest numbers of contributions were France (n = 450), Germany (n = 318), the Netherlands (n = 267), Spain (n = 225), and the UK (n = 183). 2.2% of participants (39/1779) had been diagnosed with COVID-19. There were no differences regarding age, sex, AILD, the status of liver cirrhosis, or status post liver transplantation between COVID-19 and non-COVID-19 cases. Of the 39 COVID-19 cases, five patients were admitted to a regular ward, one patient was admitted to ICU and required ventilation. CONCLUSION: In our Europe-wide, patient-oriented survey on COVID-19 in patients with AILD, we detected a low rate of COVID-19, comparable to the period prevalence of the general population. These results suggest that patients with AILD are not at elevated risk of COVID-19.

Factors influencing the failure of interferon-free therapy for chronic hepatitis C: Data from the Polish EpiTer-2 cohort study.

BACKGROUND: The introduction of direct-acting antiviral drugs into clinical practice has revolutionized the treatment of chronic hepatitis C, making it highly effective and safe for patients. However, few researchers have analyzed the factors causing therapy failure in some patients. AIM: To analyze factors influencing the failure of direct antiviral drugs in the large, multicenter EpiTer-2 cohort in a real-world setting. METHODS: The study cohort consisted of patients with chronic hepatitis C treated at 22 Polish centers from 2016-2020. Data collected from the online EpiTer-2 database included the following: hepatitis C virus (HCV) genotype, stage of fibrosis, hematology and liver function parameters, Child-Turcotte-Pugh and Model for End-stage Liver Disease scores, prior antiviral therapy, concomitant diseases, and drugs used in relation to hepatitis B virus (HBV) and/or human immunodeficiency virus (HIV) coinfections. Adverse events observed during the treatment and follow-up period were reported. Both standard and machine learning methods were used for statistical analysis. RESULTS: During analysis, 12614 patients with chronic hepatitis C were registered, of which 11938 (mean age: 52 years) had available sustained virologic response (SVR) data [11629 (97%) achieved SVR and 309 (3%) did not]. Most patients (78.1%) were infected with HCV genotype 1b. Liver cirrhosis was diagnosed in 2974 patients, while advanced fibrosis (F3) was diagnosed in 1717 patients. We included patients with features of hepatic failure at baseline [ascites in 142 (1.2%) and encephalopathy in 68 (0.6%) patients]. The most important host factors negatively influencing treatment efficacy were liver cirrhosis, clinical and laboratory features of liver failure, history of hepatocellular carcinoma, and higher body mass index. Among viral factors, genotype 3 and viral load also exerted an influence on treatment efficacy. Classical statistical analysis revealed that treatment ineffectiveness seemed to be influenced by the male sex, which was not confirmed by the multivariate analysis using the machine learning algorithm (random forest). Coinfection with HBV (including patients with on-treatment reactivation of HBV infection) or HIV, extrahepatic manifestations, and renal failure did not significantly affect the treatment efficacy. CONCLUSION: In patients with advanced liver disease, individualized therapy (testing for resistance-associated variants and response-guided treatment) should be considered to maximize the chance of achieving SVR.

Creating Effective Models for Delivering Palliative Care in Advanced Liver Disease.

PURPOSE OF REVIEW: The current healthcare system is not fully equipped to provide comprehensive support for patients with advanced liver disease (ALD) and their caregivers resulting in concomitant suffering and reduced quality of life (QoL). Integration of palliative care (PC) within routine care has demonstrated benefits in improving symptoms and QoL and reducing healthcare utilization for other serious illnesses but has been underutilized or delayed for ALD care. The purpose of this article is to outline the domains and benefits of PC and discuss the misconceptions and barriers for PC integration, and healthcare delivery models supporting PC integration within ALD care. RECENT FINDINGS: PC has eight key domains related to physical and mental health, goals for future care, and care of the caregivers. PC offers benefits to improve health outcomes and patient satisfaction and reduce healthcare utilization. To date there have been successful models of PC that are primarily hospital- or community-based; successful models have been PC specialist- or primary/generalist-led. SUMMARY: Concurrent PC within oncology has formed the basis for most evidence-based guidelines. PC integration within ALD care is still in its infancy. While amassing evidence in ALD, hepatology organizations can promote consensus-based integrated PC models that can guide research and practice efforts to increase supportive care for these patients in need and their family caregivers.

Low serum vitamin D level associated with incident advanced liver disease in the general population - a prospective study.

BACKGROUND: Vitamin D deficiency is a common finding in chronic liver disease. It has also been linked to the pathogenesis of non-alcoholic fatty liver disease, hepatic fibrogenesis, decompensation and hepatocellular carcinoma. AIMS: We analyzed whether serum vitamin D is associated with incident advanced liver disease in the general population. METHODS: Serum 25-hydroxyvitamin D was measured in 13807 individuals participating in the Finnish population-based health examination surveys FINRISK 1997 and Health 2000. Data were linked with incident advanced liver disease (hospitalization, cancer or death related to liver disease). During a follow-up of 201444 person-years 148 severe liver events occurred. Analyses were performed using multivariable Cox regression analyses. RESULTS: Vitamin D level associated with incident advanced liver disease with the hazard ratio of 0.972 (95% confidence interval 0.943-0.976, p < .001), when adjusted for age, sex, blood sampling season and stratified by cohort.The association remained robust and significant in multiple different adjustment models adjusting sequentially for 22 potential confounders. CONCLUSION: Low vitamin D level is linked to incident advanced liver disease at population level.

Leukocytes, Systemic Inflammation and Immunopathology in Acute-on-Chronic Liver Failure.

Acute-on-chronic liver failure (ACLF) is a complex syndrome that develops in patients with cirrhosis and is characterized by acute decompensation, organ failure(s) and high short-term mortality. ACLF frequently occurs in close temporal relationship to a precipitating event, such as acute alcoholic, drug-induced or viral hepatitis or bacterial infection and, in cases without precipitating events, probably related to intestinal translocation of bacterial products. Dysbalanced immune function is central to its pathogenesis and outcome with an initial excessive systemic inflammatory response that drives organ failure and mortality. This hyperinflammatory state ultimately impairs the host defensive mechanisms of immune cells, rendering ACLF patients immunocompromised and more vulnerable to secondary infections, and therefore to higher organ dysfunction and mortality. In this review, we describe the prevailing characteristics of the hyperinflammatory state in patients with acutely decompensated cirrhosis developing ACLF, with special emphasis on cells of the innate immune system (i.e., monocytes and neutrophils), their triggers (pathogen- and damage-associated molecular patterns [PAMPs and DAMPs]), their effector molecules (cytokines, chemokines, growth factors and bioactive lipid mediators) and the consequences on tissue immunopathology. In addition, this review includes a chapter discussing new emerging therapies based on the modulation of leukocyte function by the administration of pleiotropic proteins such as albumin, Toll-like receptor 4 antagonists, interleukin-22 or stem cell therapy. Finally, the importance of finding an appropriate intervention that reduces inflammation without inducing immunosuppression is highlighted as one of the main therapeutic challenges in cirrhosis.

Polypharmacy and drug interactions amongst cirrhotic patients discharged from a tertiary center: Results from a national quality improvement audit.

BACKGROUND AND STUDY AIMS: Auditing of polypharmacy is particularly essential in patients with cirrhosis because of the crucial role of liver in drug metabolism. The aim of this study was to audit the drug prescribed in this group of patients and analyzed the quantity and severity of potential drug-drug interaction. PATIENTS AND METHODS: In this cross-sectional study we analyzed the last prescription as recorded in the Electronic Medical Record at the time of discharge for cirrhotic patients who were hospitalized during 24-months study period. Data were also collected for age, gender, and diagnoses. The drugs were analyzed for cross interactions using the Lexicomp-online e-formulary. The drug interactions are classified as: class A: no known interaction, class B: no action needed, Class C: monitor therapy, class D: consider therapy modification, and Class X: the drug should be avoided. RESULTS: A total of 333 patients with cirrhosis were audited, whereas complete and relevant data were available for 181 patients (134 males, 74%) with a mean age ± SD 59.7 ± 10.1. Out of these, 168 (92.8%) patients were using at least one medicine and the total number of medications used was 808 drugs. The observed average of utilization was 7.8 ± 3.1 drugs (range = 1-17) and 102 (56.3%) patients used polypharmacy. A total of 198 (24.5%) consumed drugs were related to cirrhosis and its complications. Six (3.3%), 30 (16.6%) and 65 (35.9%) patients had Class-X, Class D, and Class C, respectively. Utilization of polypharmacy was statistical significant in patients with class X (83.3%, p = 0.03), class D (16.6%, p = 0.01), and class C (35.9%, p = 0.02). CONCLUSION: The findings highlight the importance of auditing for polypharmacy to recognize and prevent potential drug-related problems in patients with cirrhosis. Implementation of strategies to optimize medication use in patients with cirrhosis should be considered necessary as it can have a bearing on length of stay and morbidity.

Thrombocytopenia in Chronic Liver Disease: New Management Strategies.

Thrombocytopenia is common in advanced liver disease, and such patients frequently need invasive procedures. Numerous mechanisms for thrombocytopenia exist, including splenic sequestration and reduction of levels of the platelet growth factor thrombopoietin. Traditionally, platelet transfusions have been used to increase platelet counts before elective procedures, usually to a threshold of greater than or equal to 50,000/µL, but levels vary by provider, procedure, and specific patient. Recently, the thrombopoietin receptor agonists avatrombopag and lusutrombopag were studied and found efficacious for increasing platelet count in the outpatient setting for select patients with advanced liver disease who need a procedure.

Advanced liver disease outcomes after hepatitis C eradication by human immunodeficiency virus infection in PITER cohort.

BACKGROUND: Liver disease progression after Hepatitis C Virus (HCV) eradication following direct-acting antiviral (DAA) treatment in the real-life setting according to Human Immunodeficiency Virus (HIV) coinfection was evaluated. METHODS: Patients consecutively enrolled in PITER between April 2014 and June 2019 and with at least 12-weeks follow-up following treatment were analysed. Cox regression analysis were used to evaluate HIV coinfection and factors independently associated with liver disease outcomes following viral eradication in DAA treated patients with pre-treatment liver cirrhosis. RESULTS: 93 HIV/HCV coinfected and 1109 HCV monoinfected patients were evaluated during a median follow-up of 26.7 (range 6-44.6) and 24.6 (range 6.8-47.3) months, respectively. No difference in the cumulative HCC incidence and hepatic decompensation was observed between coinfected and monoinfected patients. Age (Hazard Ratio [HR] = 1.08; 95% CI 1.04-1.13), male sex (HR = 2.76; 95% CI 1.28-5.96), lower albumin levels (HR = 3.94; 95% CI 1.81-8.58), genotype 3 (HR = 5.05; 95% CI 1.75-14.57) and serum anti-HBc positivity (HR = 1.99, 95% CI 1.01-3.95) were independently associated with HCC incidence. Older age (HR = 1.03; 95% CI 1.00-1.07), male sex (HR = 2.13; 95% CI 1.06-4.26) and lower albumin levels (HR = 3.75; 95% CI 1.89-7.46) were independently associated with the appearance of a decompensating event after viral eradication. CONCLUSION: Different demographic, clinical and genotype distribution between HIV coinfected vs those monoinfected, was observed in a representative cohort of HCV infected patients in Italy. Once liver cirrhosis is established the disease progression is decreased, but still persists regardless of viral eradication in both coinfected and monoinfected patients. In patients with cirrhosis, HIV coinfection was not associated with a higher probability of liver complications, after viral eradication.

Association Between HBx Variations and Development of Severe Liver Disease Among Indonesian Patients.

Multi-site mutations in the hepatitis B virus (HBV) X gene are often found in patients with advanced liver diseases such as liver cirrhosis and hepatocellular carcinoma. It has been reported that modifications in the X protein play crucial roles in the development of HBV-related severe liver disease. However, the prevalence of genetic variations in Indonesian strains has not been systematically assessed. In this study, we sought to investigate the profile of nonsynonymous mutations in the X gene. Overall, 114 Indonesian HBV strains, including 12 in-house samples, were retrieved from GenBank. The mutation frequency in the X gene was compared among strains obtained from patients with chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The mutation frequencies of the domain and basal core promoter regions were significantly greater in advanced liver diseases compared with chronic hepatitis. In addition, the double mutation K130M/V131I and the triple mutation N88V/K130M/V131I were associated with a 2.5 times higher risk of advanced liver disease. However, the roles of two novel X gene mutations (A12S/T and L16F/P) on hepatocarcinogenesis are unclear relative to wild-type X gene. In conclusion, the development of multi-site mutations in the X gene may represent a strategy by which HBV can escape immune surveillance and thus contribute to hepatocarcinogenesis, even though the biological roles of some variants remain unclear.
