The global, regional, and national burden of cirrhosis by cause in 195 countries and territories, 1990-2017: a systematic analysis for the Global Burden of Disease Study 2017

Acute Kidney Injury in Patients with Chronic Liver Disease: A Review

Introduction

Acute kidney injury (AKI) is a frequent complication of chronic liver disease (CLD) contributing to high morbidity and mortality worldwide. While liver transplantation (LT) has shown favorable outcomes, early identification and management of AKI is imperative for survival. This review aims to highlight the epidemiology, pathophysiology, management, and prognosis of AKI in CLD.

Methods

An extensive literature search was performed using PubMed, Medline, and Google Scholar to identify literature related to epidemiology, burden, clinical presentations, prognosis, and management of AKI in CLD.

Results

The identified studies highlighted a wide range of prevalence of AKI in hospitalized patients with CLD. The etiology and pathophysiology are multifactorial and include prerenal AKI, acute tubular injury, sepsis, gastrointestinal bleeding, bacterial translocation from the gut, and hepatorenal syndrome (HRS). AKI is associated with a higher risk of morbidity and mortality and progression to chronic kidney disease following LT. Management of AKI in CLD varies based on the underlying etiology. While vasoconstrictors like terlipressin have shown great potential in the treatment of HRS-AKI and is widely used in Europe and United States, LT remains the definitive therapy of choice. In most cases, kidney replacement therapy serves as a bridge to liver transplant.

Conclusion

AKI is a serious complication of CLD and early identification is essential. Diagnosis and management, particularly HRS is challenging and requires a high index of suspicion. More research is required to identify novel therapies to improve outcomes of AKI in patients with CLD.

The landscape of liver transplantation for patients with alcohol-associated liver disease in the United States

Indications for liver transplants have expanded to include patients with alcohol-associated liver disease (ALD) over the last decade. Concurrently, the liver allocation policy was updated in February 2020 replacing the Donor Service Area with Acuity Circles (ACs). The aim is to compare the transplantation rate, waitlist outcomes, and posttransplant survival of candidates with ALD to non-ALD and assess differences in that effect after the implementation of the AC policy. Scientific Registry for Transplant Recipients data for adult candidates for liver transplant were reviewed from the post-AC era (February 4, 2020-March 1, 2022) and compared with an equivalent length of time before ACs were implemented. The adjusted transplant rates were significantly higher for those with ALD before AC, and this difference increased after AC implementation (transplant rate ratio comparing ALD to non-ALD = 1.20, 1.13, 1.61, and 1.32 for the Model for End-Stage Liver Disease categories 37-40, 33-36, 29-32, and 25-28, respectively, in the post-AC era, p < 0.05 for all). The adjusted likelihood of death/removal from the waitlist was lower for patients with ALD across all lower Model for End-Stage Liver Disease categories (adjusted subdistribution hazard ratio = 0.70, 0.81, 0.84, and 0.70 for the Model for End-Stage Liver Disease categories 25-28, 20-24, 15-19, 6-14, respectively, p < 0.05). Adjusted posttransplant survival was better for those with ALD (adjusted hazard ratio = 0.81, p < 0.05). Waiting list and posttransplant mortality tended to improve more for those with ALD since the implementation of AC but not significantly. ALD is a growing indication for liver transplantation. Although patients with ALD continue to have excellent posttransplant outcomes and lower waitlist mortality, candidates with ALD have higher adjusted transplant rates, and these differences have increased after AC implementation.

Species differences of fatty liver diseases: comparisons between human and feline

Nonalcoholic fatty liver disease (NAFLD) has emerged as the most widespread chronic liver disease that poses significant threats to public health due to changes in dietary habits and lifestyle patterns. The transition from simple steatosis to nonalcoholic steatohepatitis (NASH) markedly increases the risk of developing cirrhosis, hepatocellular carcinoma, and liver failure in patients. However, there is only one Food and Drug Administration-approved therapeutic drug in the world, and the clinical demand is huge. There is significant clinical heterogeneity among patients with NAFLD, and it is challenging to fully understand human NAFLD using only a single animal model. Interestingly, felines, like humans, are particularly prone to spontaneous fatty liver disease. This review summarized and compared the etiology, clinical features, pathological characteristics, and molecular pathogenesis between human fatty liver and feline hepatic lipidosis (FHL). We analyzed the key similarities and differences between those two species, aiming to provide theoretical foundations for developing effective strategies for the treatment of NAFLD in clinics.

Understanding and using Animal Models of Hepatotoxicity

Hepatotoxicity is a critical health hazard, primarily contributing to the increased incidence of deaths globally. The liver is one of the major and extremely vital organs of the human body. Autoimmune diseases, viruses, exposure to toxicants such as carcinogens, and changes in eating habits can all cause liver problems, among other things. Free radical generation, together with raised enzyme levels including SGOT, SGPT, and total bilirubin, are among the pathological changes set off by liver injury. Hepatotoxicity causes changes in cells, such as eosinophilic cytoplasm, nuclear pyknosis, fatty degeneration, too many liver lesions, and hepatic centrilobular necrosis due to lipid peroxidation. Researchers have used animal models to investigate liver diseases and toxicities. Drugs such as azathioprine, alcoholism, paracetamol intoxication, and anti-tuberculosis drugs are some of the most common causes of liver toxicity. These toxins cause calcium ions (Ca2+), reactive oxygen species (ROS), and inflammatory mediators to be released inside cells. This activates immune cells like NK cells, NKT cells, and Kupffer cells. These signaling pathways also play roles in hepatotoxicity. Due to its pathogenesis, no effective drug is currently available for hepatotoxicity due to a lack of understanding related to the signaling factors involved in it. The paper primarily examines different experimental models of hepatotoxicity, including non-invasive and invasive methods, as well as genetic models. As such, these models are crucial tools in advancing our understanding of hepatotoxicity, thus paving the way for new therapeutic interventions.

Clostridioides difficile infection increases in-hospital mortality, length of stay, and hospital cost but not 30-day mortality in cirrhotic patients

BACKGROUND AND AIM

Clostridioides difficile infection (CDI) is a leading cause of nosocomial infection and is associated with both higher morbidity and mortality. Cirrhotic patients are more susceptible to CDI because of impaired gut immune response, use of proton pump inhibitor, and frequent hospitalization. We aim to investigate the impact of CDI on cirrhotic patients' in-hospital and 30-day mortality, length of stay, and hospital cost.

METHODS

Potentially eligible studies were identified from Embase, Medline, and Web of Sciences databases.

RESULTS

A total of 2320 articles were identified. After reviewing, nine studies reporting in-hospital mortality and three reporting 30-day mortality of cirrhotic patients with CDI versus those without CDI were included. The meta-analysis of nine studies, consisting of 7 746 126 patients, revealed a significant association between CDI and in-hospital mortality in cirrhotic patients with the pooled OR of 1.68 (95% CI 1.29-1.85, I2 94%). Length of stay and hospital cost were also higher in the CDI group (pooled MD of 6.56 days [95% CI 5.75-7.36, I2 94%] and 27.85 (×$1000) [95% CI 10.41-45.29, I2 100%], respectively). The funnel plots for the meta-analysis of the association between CDI and in-hospital mortality, length of stay, and hospitalization cost were not suggestive of publication bias. From three studies consisting of 3694 patients, we found that CDI was not associated with 30-day mortality in cirrhotic patients (pooled OR 1.20, 95% CI 0.75-2.24, I2 74%).

CONCLUSION

CDI is associated with increased in-hospital mortality, length of stay, and hospital costs, but not with 30-day mortality in cirrhotic patients.

The role of noninvasive biomarkers for monitoring cell injury in advanced liver fibrosis

INTRODUCTION

Accurate and reliable diagnosis and monitoring of hepatic fibrosis is increasingly important given the variable natural history in chronic liver disease (CLD) and expanding antifibrotic therapeutic options targeting reversibility of early-stage cirrhosis. This highlights the need to develop more refined and effective noninvasive techniques for the dynamic assessment of fibrogenesis and fibrolysis.

AREAS COVERED

We conducted a literature review on PubMed, from 1 December 1970, to 1 November 2024, to evaluate and compare available blood-based and imaging-based noninvasive tools for hepatic fibrosis diagnosis and monitoring. Simple scores such as FIB-4 and NAFLD fibrosis score are suitable for excluding significant or advanced fibrosis, while tertiary centers should adopt complex scores and liver stiffness measurement as part of a secondary diagnostic and more comprehensive evaluation. Moreover, the advent of multiomics for high-resolution molecular profiling, and integration of artificial intelligence for noninvasive diagnostics holds promise for revolutionizing fibrosis monitoring and treatment through novel biomarker discovery and predictive omics-based algorithms.

EXPERT OPINION

The increased shift toward noninvasive diagnostics for liver fibrosis needs to align with personalized medicine, enabling more effective, tailored management strategies for patients with liver disease in the future.

Machine-learning-based plasma metabolomic profiles for predicting long-term complications of cirrhosis

BACKGROUND AND AIMS

The complications of liver cirrhosis occur after long asymptomatic stages of progressive fibrosis and are generally diagnosed late. We aimed to develop a plasma metabolomic-based score tool to predict these events.

APPROACH AND RESULTS

We enrolled 64,005 UK biobank participants with metabolomic profiles. Participants were randomly divided into the training (n=43,734) and validation cohorts (n=20,271). Liver cirrhosis complications were defined as hospitalization for liver cirrhosis or presentation with HCC. An interpretable machine-learning framework was applied to learn the metabolomic states extracted from 168 circulating metabolites in the training cohort. An integrated nomogram was developed and compared to conventional and genetic risk scores. We created 3 groups: low-risk, middle-risk, and high-risk through selected cutoffs of the nomogram. The predictive performance was validated through the area under a time-dependent receiver operating characteristic curve (time-dependent AUC), calibration curves, and decision curve analysis. The metabolomic state model could accurately predict the 10-year risk of liver cirrhosis complications in the training cohort (time-dependent AUC: 0.84 [95% CI: 0.82-0.86]), and outperform the fibrosis-4 index (time-dependent AUC difference: 0.06 [0.03-0.10]) and polygenic risk score (0.25 [0.21-0.29]). The nomogram, integrating metabolomic state, aspartate aminotransferase, platelet count, waist/hip ratio, and smoking status showed a time-dependent AUC of 0.930 at 3 years, 0.889 at 5 years, and 0.861 at 10 years in the validation cohort, respectively. The HR in the high-risk group was 43.58 (95% CI: 27.08-70.12) compared with the low-risk group.

CONCLUSIONS

We developed a metabolomic state-integrated nomogram, which enables risk stratification and personalized administration of liver-related events.

Cirrhosis in primary practice: many patients remain potentially undiagnosed and are not receiving liver cancer surveillance

BACKGROUND AND AIM

Most patients with cirrhosis have compensated disease and are cared for in primary care; however, the exact epidemiology within Australia remains largely unknown. The aim of this study was to assess cirrhosis care in an Australian primary care setting by evaluating rates of cirrhosis diagnosis, appropriate hepatocellular carcinoma (HCC) surveillance and specialist communication.

METHODS

Electronic medical records in consenting general practices were reviewed using the "Liver Toolkit" to identify patients with an existing cirrhosis diagnosis. Individual cases were reviewed to identify outcomes of interest.

RESULTS

One hundred seventy-one patients with confirmed cirrhosis across nine general practices were identified (74% male, mean age: 61.2 years). There was significant variation in the rate of cirrhosis diagnosis between practices (range 31.7-637.9 per 100 000 patients, P < 0.0001). Patients with cirrhosis had predominately compensated disease (75% Child-Pugh A) and common etiologies of cirrhosis were alcohol (49%), hepatitis C (47%), and metabolic dysfunction-associated steatotic liver disease (29%). Forty-two patients (25%) had received appropriate HCC surveillance. Predictors of inadequate HCC surveillance were time from last specialist correspondence (odds ratio [OR] = 1.06 per month increase, 95% confidence interval [CI]: 1.02-1.10, P = 0.002) and hepatitis B (OR = 0.24, 95% CI: 0.06-0.98, P = 0.047). Specialist correspondence with primary care was older than 2 years or absent in 37% of cases.

CONCLUSIONS

There was a 20-fold difference in the rate of cirrhosis diagnosis between general practices within Sydney, suggesting a large proportion of patients remain undiagnosed. Three quarters of patients with diagnosed cirrhosis are not receiving appropriate HCC surveillance.

The effect and application of adiponectin in hepatic fibrosis

Hepatic fibrosis, a degenerative liver lesion, significantly contributes to the deterioration and mortality among patients with chronic liver diseases. The condition arises from various factors including toxins, such as alcohol, infections like different types of viral hepatitis, and metabolic diseases. Currently, there are no effective treatments available for liver fibrosis. Recent research has shown that adiponectin (ADPN) exhibits inhibitory effects on hepatic fibrosis. ADPN, an adipocytokine secreted by mature adipocytes, features receptors that are widely distributed across multiple tissues, especially the liver. In the liver, direct effects of ADPN on liver fibrosis include reducing inflammation and regulating hepatic stellate cell proliferation and migration. And its indirect effects include alleviating hepatic endoplasmic reticulum stress and reducing inflammation in hepatic lobules, thereby mitigating hepatic fibrosis. This review aims to elucidate the regulatory role of ADPN in liver fibrosis, explore how ADPN and its receptors alleviate endoplasmic reticulum stress, summarize ADPN detection methods, and discuss its potential as a novel marker and therapeutic agent in combating hepatic fibrosis.

Leukocyte telomere length decreased the risk of mortality in patients with alcohol-associated liver disease

Background

It is necessary to find latent indicators to predict the survival of alcohol-associated liver disease (ALD) patients. Leukocyte telomere length (LTL) was regarded as an indicator of prognosis in several diseases. However, the relationships between LTL and survival as well as cause-specific mortality in ALD patients were still unknown.

Objective

This study aimed at exploring the underlying link between LTL and the risk of mortality in patients with ALD.

Methods

The LTL and survival data were gathered from the National Health and Nutrition Examination Survey (NHANES) 1999-2002. The connection between LTL and mortality was assessed by Cox regression models and stratified analyses. The non-linear relationship was explored by restricted cubic spline (RCS) analysis. Sensitivity analyses were used to evaluate the robustness of our findings.

Results

LTL was a negative factor for all-cause mortality (all p-value < 0.05). The risk of cardiovascular disease (CVD)-related death was decreased in Q3 (p < 0.001) and Q4 levels of LTL (p < 0.001) compared with the Q1 group. Shorter LTL resulted in higher cancer-caused mortality (p = 0.03) in the Q2 group. Longer LTL improved survival especially for elder patients (p for trend < 0.001) or men (p for trend = 0.001). Moreover, there were L-shaped correlations between LTL and all-cause mortality (p for non-linearity = 0.02), as well as cancer-related mortality (p for non-linearity < 0.001). Four sensitivity analyses proved the robustness of our findings.

Conclusion

Our research found that longer LTL improved survival in patients with ALD and decreased CVD and cancer-related mortality. LTL decreased all-cause mortality especially for patients older than 65 years or men. LTL might be a useful biomarker for prognosis among patients with ALD. More prospective studies are needed to assess the relevance between LTL and mortality and explore the underlying mechanisms between them.

High-throughput platform for label-free sorting of 3D spheroids using deep learning

End-stage liver diseases have an increasing impact worldwide, exacerbated by the shortage of transplantable organs. Recognized as one of the promising solutions, tissue engineering aims at recreating functional tissues and organs in vitro. The integration of bioprinting technologies with biological 3D models, such as multi-cellular spheroids, has enabled the fabrication of tissue constructs that better mimic complex structures and in vivo functionality of organs. However, the lack of methods for large-scale production of homogeneous spheroids has hindered the upscaling of tissue fabrication. In this work, we introduce a fully automated platform, designed for high-throughput sorting of 3D spheroids based on label-free analysis of brightfield images. The compact platform is compatible with standard biosafety cabinets and includes a custom-made microscope and two fluidic systems that optimize single spheroid handling to enhance sorting speed. We use machine learning to classify spheroids based on their bioprinting compatibility. This approach enables complex morphological analysis, including assessing spheroid viability, without relying on invasive fluorescent labels. Furthermore, we demonstrate the efficacy of transfer learning for biological applications, for which acquiring large datasets remains challenging. Utilizing this platform, we efficiently sort mono-cellular and multi-cellular liver spheroids, the latter being used in bioprinting applications, and confirm that the sorting process preserves viability and functionality of the spheroids. By ensuring spheroid homogeneity, our sorting platform paves the way for standardized and scalable tissue fabrication, advancing regenerative medicine applications.

Systems of care that improve outcomes for people with hepatic encephalopathy

Hepatic encephalopathy (HE) is a critical neuropsychiatric complication of liver cirrhosis with a significant impact on patient quality of life and survival. The global prevalence of cirrhosis and associated HE necessitates a comprehensive understanding of the condition and effective systems of care to optimize outcomes. This review addresses the epidemiology, classification, diagnosis, and management of HE, with an emphasis on systems of care that improve outcomes for people with HE. Current diagnostic challenges include differentiating cognitive deficits attributable to HE from those caused by other etiologies, highlighting the need for accurate diagnostic methods. Traditional psychometric tests, while valuable for diagnosing covert HE (CHE), are limited in their ability to predict overt HE (OHE) due to various confounding factors. As a result, non-psychometric tools have been developed to provide outcome-based predictions aligned with the clinical course of HE. The management of HE includes addressing precipitating factors, pharmacologic interventions to reduce ammonia levels, and supportive care, with lactulose and rifaximin playing a central role. Preventive strategies with the use of remote monitoring in the outpatient management of HE, integrating technology for real-time tracking of therapy compliance and symptom evolution, could contribute to reducing hospital readmissions and improving patient care.

Global, Regional, and National Trends in Liver Disease-Related Mortality Across 112 Countries From 1990 to 2021, With Projections to 2050: Comprehensive Analysis of the WHO Mortality Database

BACKGROUND

Liver disease causes over two million deaths annually worldwide, comprising approximately 4% of all global fatalities. We aimed to analyze liver disease-related mortality trends from 1990 to 2021 using the World Health Organization (WHO) Mortality Database and forecast global liver disease-related mortality rates up to 2050.

METHODS

This study examined age-standardized liver disease-related death rates from 1990 to 2021, employing data from the WHO Mortality Database across 112 countries across five continents. The rates over time were calculated using a locally weighted scatter plot smoother curve, with weights assigned based on the population of each country. Furthermore, this study projected liver disease-related mortality rates up to 2050 using a Bayesian age-period-cohort (BAPC) model. Additionally, a decomposition analysis was conducted to discern influencing factors such as population growth, aging, and epidemiological changes.

RESULTS

The estimated global age-standardized liver disease-related mortality rates surged significantly from 1990 to 2021 across 112 countries, rising from 103.4 deaths per 1,000,000 people (95% confidence interval [CI], 88.16, 118.74) in 1990 to 173.0 deaths per 1,000,000 people (95% CI, 155.15, 190.95) in 2021. This upward trend was particularly pronounced in low- and middle-income countries, in Africa, and in populations aged 65 years and older. Moreover, age-standardized liver disease-related mortality rates were correlated with a lower Human Development Index (P < 0.001) and sociodemographic index (P = 0.001). According to the BAPC model, the projected trend indicated a sustained and substantial decline in liver disease-related mortality rates, with an estimated decrease from 185.08 deaths per 1,000,000 people (95% CI, 179.79, 190.63) in 2021 to 156.29 (112.32, 214.77) in 2050. From 1990 to 2021, age-standardized liver disease-related deaths surged primarily due to epidemiological changes, whereas from 1990 to 2050, the impact of population aging and growth became the primary contributing factors to the overall increase.

CONCLUSION

Global age-standardized liver disease-related mortality has increased significantly and continues to emerge as a crucial global public health issue. Further investigation into liver disease-related mortality rates in Africa is needed, and updating policies is necessary to effectively manage the global burden of liver disease.

Alcohol-associated liver cancer

Heavy alcohol intake induces a wide spectrum of liver diseases ranging from steatosis, steatohepatitis, cirrhosis, and HCC. Although alcohol consumption is a well-known risk factor for the development, morbidity, and mortality of HCC globally, alcohol-associated hepatocellular carcinoma (A-HCC) is poorly characterized compared to viral hepatitis-associated HCC. Most A-HCCs develop after alcohol-associated cirrhosis (AC), but the direct carcinogenesis from ethanol and its metabolites to A-HCC remains obscure. The differences between A-HCC and HCCs caused by other etiologies have not been well investigated in terms of clinical prognosis, genetic or epigenetic landscape, molecular mechanisms, and heterogeneity. Moreover, there is a huge gap between basic research and clinical practice due to the lack of preclinical models of A-HCC. In the current review, we discuss the pathogenesis, heterogeneity, preclinical approaches, epigenetic, and genetic profiles of A-HCC, and discuss the current insights into and the prospects for future research on A-HCC. The potential effect of alcohol on cholangiocarcinoma and liver metastasis is also discussed.

Follow-up post-HCV virological response to DAA in advanced chronic liver disease

Direct-acting antivirals (DAA) achieve high virological response rates with minimal side effects for many patients. Despite their significant impact on the progression and epidemiology of hepatitis C virus (HCV) associated liver disease, the global annual incidence of chronic infections is expected to remain relatively constant, averaging 1.42 million new cases each year until 2030. Furthermore, by 2030, there will be a 14-17% increase in end-stage liver disease outcomes such as liver-related deaths, hepatocellular carcinoma (HCC), and decompensated cirrhosis in adults aged 18 years and over. Although reductions in liver decompensation, HCC occurrence, and mortality have been shown in patients with advanced liver disease who achieved sustained virological response (SVR) with DAA, these benefits may be less significant in those with decompensated liver cirrhosis. This review aims to summarise the impact of the virological response to DAA on liver disease progression and outcomes in patients with advanced chronic liver disease, which appears to be crucial for defining patient-specific follow-up.

Prevalence, trends, and distribution of hepatitis C virus among the general population in sub-Saharan Africa: A systematic review and meta-analysis

BACKGROUND AND AIMS

Although the evidence is uncertain, existing estimates for hepatitis C virus (HCV) in sub-Saharan Africa (SSA) indicate a high burden. We estimated HCV seroprevalence and viraemic prevalence among the general population in SSA.

METHODS

We searched Medline, Embase, Web of Science, APA PsycINFO, and World Health Organization Africa Index Medicus for community-based studies. Study quality was assessed using the Joanna Briggs Institute critical appraisal tool, and heterogeneity using the index of heterogeneity (I2). Two approaches were deployed. First, we used random-effects meta-analysis to pool prevalence. Second, to derive representative estimates, we weighted each country's HCV seroprevalence using 2021 United Nations country population sizes.

RESULTS

We synthesized 130 studies. Overall, SSA HCV seroprevalence from the random-effects model was 4.17% (95% confidence interval [CI]: 3.71-4.66, I2 = 99.30%). There were no differences between males (4.31%) and females (4.03%). Seroprevalence was 2.25%, 3.31%, and 16.23% for ages ≤20, 21-64, and ≥65 years, respectively, and was higher in rural (6.63%) versus urban (2.93%). There was indication of decrement overtime from 5.74% to 4.35% to 3.03% in the years 1984-2000, 2001-2014, and 2015-2023, respectively. The weighted overall SSA HCV seroprevalence was estimated to be 2.30% (95% CI: 1.59-3.00) with regional variation: Africa-Southern (.79%), Africa-Central (1.47%), Africa-Eastern (2.71%), and Africa-Western (2.88%). HCV viremia among HCV seropositives was 54.77% (95% CI: 47.80-61.66).

CONCLUSIONS

HCV seroprevalence in SSA remains high. Populations aged ≥65 years, rural communities, Africa-Western, and some countries in Africa-Central and Africa-Eastern appear disproportionately affected. These results underline the need for governmental commitment to achieve the 2030 global HCV elimination targets.

Utility of Quantitative Assessment of Tc-99m-diethylenetriamine-penta-acetic acid-galactosyl Human Serum Albumin SPECT/CT in the Identification of Severe Liver Fibrosis: Its Complementary Diagnostic Value with Other Liver Function Indices

PURPOSE

To evaluate the value of Tc-99m-diethylenetriamine-penta-acetic acid-galactosyl human serum albumin (99mTc-GSA) single photon emission computed tomography (SPECT) for assessing liver fibrosis, and to assess its complementary value to other liver function indices such as fibrosis-4 (FIB-4) index and indocyanine green (ICG) clearance test parameters (ICG-R15 and ICG-K).

PROCEDURES

Seventy-eight patients with chronic liver disease and hepatocellular carcinoma who underwent 99mTc-GSA scintigraphy and other liver function tests including ICG test and FIB-4 index prior to hepatectomy were studied. 99mTc-GSA imaging was performed with SPECT/CT scanner (Discovery NM/CT 670). Immediately after injection of 99mTc-GSA, dynamic imaging was performed for 20 min, followed by SPECT data acquisition for 6 min. LHL15 which is a conventional index by 99mTc-GSA planar images, and liver uptake ration (LUR) was measured from 99mTc-GSA SPECT images. From the liver resection specimens, the degree of liver fibrosis was graded according to the Ludwig scale (F0-4).

RESULTS

Significant differences in LUR, LHL15, ICG-R15, ICG-K, platelet count and FIB-4 index were found between the F0-3 and F4 liver fibrosis patient groups (P < 0.05). Multivariate logistic regression analysis revealed that LUR and ICG-K were independent factors for identifying severe liver fibrosis (F4). Area under the curve of receiver operating curve analysis for the logistic regression model using LUR and ICG-K was 0.83. In the patient group with higher FIB-4 (≥ 3.16), the diagnostic performance of LUR for detecting severe liver fibrosis was significantly better than LHL15 (AUC: 0.83 vs. 0.75, P = 0.048). In the high FIB-4 index group, the sensitivity and specificity for identifying F4 was 88% and 85%, respectively, with LUR cutoff value of 41.2%.

CONCLUSIONS

LUR, measured by 99mTc-GSA SPECT, is a useful indicator for identifying sever liver fibrosis. Particularly in patients with high FIB-4 index (≥ 3.16), LUR can be a valuable indicator to identify severe liver fibrosis with high diagnostic accuracy.

Alcohol-associated liver disease-Global epidemiology

Alcohol-associated liver disease (ALD), as highlighted in this narrative review, is a major public health concern, increasingly impacting global disease burden and premature mortality. In 2019, ALD accounted for the loss of 11 million life-years worldwide. The rising number of deaths and disability-adjusted life-years attributed to ALD, particularly pronounced in the United States, are alarming. Projections suggest that the economic impact of ALD, as seen in the United States, could potentially double by 2040. ALD is increasingly prevalent among younger adults (20-45 y) and has become the leading cause of liver transplantation in both United States and Europe. During the COVID-19 pandemic, the existing trend was further amplified as high-risk drinking patterns coincided with a rise in hospital admissions for alcohol-associated hepatitis and increased ALD-related mortality. The prevalence of ALD is estimated at 3.5% in the general population, 26.0% among hazardous drinkers, and 55.1% among those with alcohol use disorders. Alarmingly, 5-year mortality rates for patients with ALD exceed 50%, with even higher rates in more advanced disease stages. Methodological challenges, such as underreporting, diagnostic difficulties, and variability in registry data quality, complicate the accurate assessment of the impact of ALD. Additionally, the contribution of alcohol to the progression of other liver diseases is often under acknowledged in health care registries, leading to a significant underestimation of its broader implications for liver health. Addressing the growing ALD concern requires robust public health initiatives, heightened awareness, refined diagnostic techniques, and comprehensive epidemiological studies. These measures are vital to tackle the increasing prevalence of ALD and mitigate its extensive impact on individuals and health care systems.

Global burden of liver cirrhosis 1990-2019 and 20 years forecast: results from the global burden of disease study 2019

BACKGROUND

Cirrhosis is a disease that imposes a heavy burden worldwide, but its incidence varies widely by region. Therefore, we analysed data on the incidence and mortality of cirrhosis in 204 countries and territories from 1990-2019 and projected the disease development from 2019-2039.

METHODS

Data on the incidence and mortality of liver cirrhosis from 1990 to 2019 were acquired from the public Global Burden of Disease (GBD) study. In addition, the average annual percentage change (AAPC) and estimated annual percentage change (EAPC) of the age-standardized rate (ASR) of cirrhosis in different regions were calculated. The estimates of risk factor exposure were summarized, and the proportion of causes and risk factors of liver cirrhosis and their relationship with the human development index (HDI) and socio-demographic index (SDI) were analysed. Trends in the incidence of cirrhosis in 2019-2039 were predicted using Nordpred and BAPC models.

RESULTS

Globally, the ASR of cirrhosis incidence decreased by 0.05% per year from 25.7/100,000 in 1990 to 25.3/100,000 in 2019. The mortality risk associated with cirrhosis is notably lower in females than in males (13 per 100,000 vs 25 per 100,000). The leading cause of cirrhosis shifted from hepatitis B to C. Globally, alcohol use increased by 14%. In line, alcohol use contributed to 49.3% of disability-adjusted life years (DALYs) and 48.4% of global deaths from liver cirrhosis. Countries with a low ASR in 1990 experienced a faster increase in cirrhosis, whereas in 2019, the opposite was observed. In countries with high SDI, the ASR of cirrhosis is generally lower. Finally, projections indicate that the number and incidence of cirrhosis will persistently rise from 2019-2039.

CONCLUSIONS

Cirrhosis poses an increasing health burden. Given the changing etiology, there is an imperative to strengthen the prevention of hepatitis C and alcohol consumption, to achieve early reduce the incidence of cirrhosis.

Liver transplantation for alcohol-associated liver disease

Alcohol-associated liver disease (ALD) is a major cause of morbidity and mortality worldwide, and a leading indication for liver transplantation (LT) in many countries, including the United States. However, LT for ALD is a complex and evolving field with ethical, social, and medical challenges. Thus, it requires a multidisciplinary approach and individualized decision-making. Short-term and long-term patient and graft survival of patients undergoing LT for ALD are comparable to other indications, but there is a continued need to develop better tools to identify patients who may benefit from LT, improve the pretransplant and posttransplant management of ALD, and evaluate the impact of LT for ALD on the organ donation and transplantation systems. In this review, we summarize the current evidence on LT for ALD, from alcohol-associated hepatitis to decompensated alcohol-associated cirrhosis. We discuss the indications, criteria, outcomes, and controversies of LT for these conditions and highlight the knowledge gaps and research priorities in this field.

Resting energy expenditure in patients with liver cirrhosis: Indirect calorimetry vs. predictive equations

BACKGROUND AND OBJECTIVES

The objective of our study was to explore the accuracy of previously published prediction equations in predicting resting energy expenditure (REE) in patients with liver cirrhosis (LC). We also aimed to develop a novel equation to estimate REE for Chinese patients with LC.

METHODS AND STUDY DESIGN

In 90 patients with LC, the agreement between REE measured by Indirect calorimetry (IC) and predictive equations was quantified using paired T-test and visualized using a Bland-Altman Plot. Pearson correlation coefficient (R) was used to measure a linear correlation between REE measured by IC and different predictive equations. Stepwise multiple regression analysis was used to create a new REE equation.

RESULTS

The estimated REEs of previous equations were underestimated against REE measured by IC (1610 ± 334 kcal). Lean body mass (LBM) was positively correlated with REE measured by IC (r = 0.723, p < 0.01). The newly derived estimation equation for REE (kcal) was 1274.3 - 209.0 * sex - 5.73 * age + 3.69 * waist circumference + 22.89 * LBM. The newly derived estimation equation was found to have a Pearson-r value of 0.765 compared with REE measured by IC.

CONCLUSIONS

REE in liver cirrhosis was underestimated by using predictive equations. The new predictive equation developed by using age, sex, waist circumference, and LBM may help estimate REE in Chinese patients with LC accurately and easily.

Shared genetic architecture of non-viral cirrhosis with several pleiotropic traits: A nested case-control study in the UK Biobank

Background & Aims

Cirrhosis is a leading cause of liver-related mortality and a multifactorial disease. To date, the complex genetic architecture of non-viral cirrhosis has not been fully explored. Cross-trait genetic correlations can elucidate the common genetic etiology of genetically correlated phenotypes. This study aims to identify polygenic and pleiotropic traits associated with cirrhosis using the linkage disequilibrium score regression analysis.

Methods

We conducted genome-wide association analysis of 9,622,842 imputed SNPs on 3,368 non-viral cirrhosis cases and 258,258 controls, and cross-trait analysis between non-viral cirrhosis and various polygenic and pleiotropic traits using the UK Biobank cohort study. We further performed sensitivity analyses by removing genomic regions of alcohol intake, smoking behaviors, and obesity. We observed multiple traits showing robust genetic correlations (rg) with non-viral cirrhosis.

Results

We found strong genetic correlations between the genetic architectures of non-viral cirrhosis and clinical/physiologic factors, including BMI (rg=0.82), alanine aminotransferase (0.71), diabetes (0.70), number of cigarettes currently smoked daily (0.67), amount of alcohol drunk on a typical drinking day (0.60), insomnia (0.59), gout (0.57), depression (0.50), apoliprotein-A (-0.33), HDL cholesterol (-0.49). Exclusion of genomic regions associated with alcohol intake, smoking behaviors, and obesity demonstrated consistent directions and persistent associations in genetic patterns. The inheritability of cirrhosis on the observed scale showed 0.56%.

Conclusions

This study provides a comprehensive assessment of the shared genetic architecture of non-viral cirrhosis predisposition and numerous polygenic and pleiotropic traits, most notably BMI, alanine aminotransferase, and diabetes. These findings provide new information on underlying comorbid conditions that can increase the non-viral cirrhosis risk.

Top-Down Proteomics Identifies Plasma Proteoform Signatures of Liver Cirrhosis Progression

Cirrhosis, advanced liver disease, affects 2 to 5 million Americans. While most patients have compensated cirrhosis and may be fairly asymptomatic, many decompensate and experience life-threatening complications such as gastrointestinal bleeding, confusion (hepatic encephalopathy), and ascites, reducing life expectancy from 12 to less than 2 years. Among patients with compensated cirrhosis, identifying patients at high risk of decompensation is critical to optimize care and reduce morbidity and mortality. Therefore, it is important to preferentially direct them towards specialty care which cannot be provided to all patients with cirrhosis. We used discovery top-down proteomics to identify differentially expressed proteoforms (DEPs) in the plasma of patients with progressive stages of liver cirrhosis with the ultimate goal to identify candidate biomarkers of disease progression. In this pilot study, we identified 209 DEPs across three stages of cirrhosis (compensated, compensated with portal hypertension, and decompensated), of which 115 derived from proteins enriched in the liver at a transcriptional level and discriminated the three stages of cirrhosis. Enrichment analyses demonstrated DEPs are involved in several metabolic and immunological processes known to be impacted by cirrhosis progression. We have preliminarily defined the plasma proteoform signatures of cirrhosis patients, setting the stage for ongoing discovery and validation of biomarkers for early diagnosis, risk stratification, and disease monitoring.

Modulation of brain energy metabolism in hepatic encephalopathy: impact of glucose metabolic dysfunction

Cerebral function is linked to a high level of metabolic activity and relies on glucose as its primary energy source. Glucose aids in the maintenance of physiological brain activities; as a result, a disruption in metabolism has a significant impact on brain function, launching a chain of events that leads to neuronal death. This metabolic insufficiency has been observed in a variety of brain diseases and neuroexcitotoxicity disorders, including hepatic encephalopathy. It is a significant neurological complication that develops in people with liver disease, ranging from asymptomatic abnormalities to coma. Hyperammonemia is the main neurotoxic villain in the development of hepatic encephalopathy and induces a wide range of complications in the brain. The neurotoxic effects of ammonia on brain function are thought to be mediated by impaired glucose metabolism. Accordingly, in this review, we provide an understanding of deranged brain energy metabolism, emphasizing the role of glucose metabolic dysfunction in the pathogenesis of hepatic encephalopathy. We also highlighted the differential metabolic profiles of brain cells and the status of metabolic cooperation between them. The major metabolic pathways that have been explored are glycolysis, glycogen metabolism, lactate metabolism, the pentose phosphate pathway, and the Krebs cycle. Furthermore, the lack of efficacy in current hepatic encephalopathy treatment methods highlights the need to investigate potential therapeutic targets for hepatic encephalopathy, with regulating deficient bioenergetics being a viable alternative in this case. This review also demonstrates the importance of the development of glucose metabolism-focused disease diagnostics and treatments, which are now being pursued for many ailments.

The association between alcohol consumption and cardiometabolic factors and liver fibrosis in metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction and alcohol-associated liver disease

BACKGROUND

The relationships between alcohol consumption, cardiometabolic factors, and liver fibrosis in patients with metabolic dysfunction-associated steatotic liver disease and those with metabolic dysfunction and alcohol-associated liver disease remain unclear.

AIMS

To investigate the longitudinal associations among alcohol consumption, cardiometabolic factors, and liver fibrosis in patients with these two liver diseases.

METHODS

This observational cohort study included 1866 patients with metabolic dysfunction-associated steatotic liver disease and 521 patients with metabolic dysfunction and alcohol-associated liver disease who underwent > two health checkups over >2 years. The associations of both liver diseases with worsening non-invasive liver fibrosis scores were assessed using the Cox regression analysis.

RESULTS

Both liver diseases independently worsened liver fibrosis in both sexes. However, the hazard ratio for worsening liver fibrosis in females was significantly higher with metabolic dysfunction and alcohol-associated liver disease than with metabolic dysfunction-associated steatotic liver disease. Worsening liver fibrosis was not associated with alcohol consumption. Among males with metabolic dysfunction-associated steatotic liver disease, the hazard ratio for worsening liver fibrosis was significantly higher in those with multiple cardiometabolic factors compared to those with a single cardiometabolic factor.

CONCLUSIONS

Although both metabolic steatotic liver disease and metabolic alcohol-associated liver disease were correlated with liver fibrosis progression in both sexes, the impact of alcohol consumption and cardiometabolic factors on fibrosis progression differed by sex. Cardiometabolic factors may have a stronger impact on liver fibrosis than alcohol consumption in males with metabolic dysfunction-associated steatotic liver disease.

Low-to-moderate alcohol consumption is associated with increased fibrosis in individuals with metabolic dysfunction-associated steatotic liver disease

BACKGROUND & AIMS

Both metabolic dysfunction and alcohol consumption cause steatotic liver disease (SLD). The distinction between metabolic dysfunction-associated SLD (MASLD) and MetALD categories is based on arbitrary thresholds of alcohol intake. Thus, we assessed the impact of different levels of alcohol consumption on SLD severity and their interaction with metabolic comorbidities.

METHODS

We performed a population-based study with transient elastography (FibroScan®) data from participants in Spain (derivation cohort) and the US (validation cohort). A controlled attenuation parameter ≥275 dB/m was used to define SLD. At least one cardiometabolic risk factor was required to define MASLD. Among patients with MASLD, low alcohol consumption was defined as an average of 5-9 drinks/week, moderate consumption as 10-13 drinks/week for females and 10-20 drinks/week for males, and increased alcohol intake (MetALD) as 14-35 drinks/week for females and 21-42 drinks/week for males. Significant fibrosis was defined as a liver stiffness measurement ≥8 kPa and at-risk metabolic dysfunction-associated steatohepatitis (MASH) as a FAST score ≥0.35.

RESULTS

The derivation cohort included 2,227 individuals with MASLD (9% reported low, 14% moderate alcohol consumption) and 76 cases with MetALD. Overall prevalences of significant fibrosis and at-risk MASH were 7.6% and 14.8%, respectively. In the multivariable analysis, alcohol consumption was independently associated with significant fibrosis and at-risk MASH. A dose-dependent increase in the prevalence of significant fibrosis and at-risk MASH was observed between the number of drinks/week and the number of cardiometabolic factors. The validation cohort included 1,732 participants with MASLD, of whom 17% had significant fibrosis and 13% at-risk MASH. This cohort validated the association between moderate intake and MASLD at risk of progression (odds ratio 1.69, 95% CI 1.06-2.71).

CONCLUSIONS

Moderate alcohol intake is commonly seen in MASLD and increases the risk of advanced disease to a level similar to that observed in MetALD.

IMPACT AND IMPLICATIONS

Metabolic risk factors such as overweight, diabetes or dyslipidemia, and alcohol consumption can cause liver disease. These factors frequently coexist, but their joint effects on liver fibrosis remain uncertain. In this study, we have analyzed individuals from the general population with MASLD (metabolic dysfunction-associated steatotic liver disease) enrolled in Spain and the US. We show that moderate alcohol consumption has a supra-additive effect with metabolic risk factors, exponentially increasing the risk of liver fibrosis. These results suggest that there are no safe limits of daily alcohol intake in patients with unhealthy metabolic status and MASLD.

An analysis of the burden of liver cirrhosis: Differences between the global, China, the United States and India

BACKGROUND

Cirrhosis continues to be the most common cause of chronic liver disease-related deaths globally, which puts significant strain on global health. This report aims to investigate the patterns of cirrhosis in China, the United States, India and worldwide from 1990 to 2019 through an epidemiological analysis of the disease utilizing data from the Global Burden of Disease Study (GBD) 2019 database.

METHODS

Download the GBD database's statistics on liver cirrhosis deaths and Disability-Adjusted Life Years for the years 1990-2019 worldwide as well as for China, the United States and India. Utilize techniques like age-period-cohort interaction, decomposition analysis, study of health inequities, Joinpoint model and Bayesian Average Annual Percentage Change model to process the data.

RESULTS

The main age group affected by cirrhosis disease, according to the results, is 50-69 years old. According to the Joinpoint model, there has been a negative worldwide Average Annual Percent Change (AAPC) in the burden of cirrhosis between 1990 and 2019. Only the USA's AAPC is positive out of the three nations that were evaluated (albeit its 95% confidence interval spans 0). These are China, India and the United States. Forecasting models indicate that the prevalence of cirrhosis will keep rising in the absence of government action. According to decomposition analysis, the main factors contributing to the rising burden of cirrhosis are population ageing and size, whereas changes in the disease's epidemiology slow the disease's growth. Research on health disparities indicates that, between 1990 and 2019, there was a downward trend in health disparities between various locations.

CONCLUSION

Health organizations across different areas should take aggressive measures to address the worrisome prevalence of cirrhosis.

Telemedicine in the tertiary liver unit: A feasibility study

Aim of the study

Chronic liver disease is a global cause of morbidity and mortality. Slovakia has a high prevalence but an inadequate hepatology network. The COVID-19 pandemic catalysed telemedicine (TM) as a potential solution, which we aimed to investigate.

Material and methods

We conducted a retrospective cohort study to evaluate the feasibility and benefits of TM for liver cirrhosis and posttransplant patients, consisting of two phases, TM1 and TM2. The main outcomes were 1) cumulative endpoint of feasibility, uptake/acceptance, adherence (TM1), and fidelity (TM1, TM2), 2) the potential to reduce the length of hospital stay, avert unnecessary hospital admissions, and expedite the search/recall process in case of serious signals mediated by TM. Although not analysed in this study, we have recorded variables necessary for investigating associations of TM use with clinical outcomes and healthcare expenditure.

Results

The study included 95 patients. The adherence documented by the termination of monitoring at the designated time was higher in TM2 (81.7% vs. 58.3%). The proportion of patients terminated due to death or the physician's decision decreased (16.9% vs. 29.2%) and was based on their discretion, unrelated to any health complications (1.4% vs. 12.5%). The clinical impact was reflected in the hospitalization rate, particularly shortened hospitalization in 11.3%, averted/prevented hospital admissions in 14.1%, and accelerated rehospitalization in 11.3% in the subsequent phase with alert-based interventions.

Conclusions

This study showed that adherence to TM was high and integrating TM helps to reduce hospitalization rates. Despite the identified limitations, TM has the potential to improve the quality and substantially reduce the cost of care.

Type-I interferon shapes peritoneal immunity in cirrhosis and drives caspase-5-mediated progranulin release upon infection

BACKGROUND & AIMS

Gut bacterial translocation contributes to immune dysfunction and spontaneous bacterial peritonitis (SBP) in cirrhosis. We hypothesized that exposure of peritoneal macrophages (PMs) to bacterial DNA results in type-I interferon (IFN) production, shaping subsequent immune responses, inflammasome activation, and the release of damage-associated molecular patterns (DAMPs).

METHODS

PMs from patients with cirrhosis were stimulated with E. coli single-stranded DNA (ssDNA), lipopolysaccharide and IFN, or infected with E. coli, S. aureus, and Group B streptococcus in vitro. Cytokine release, inflammasome activation, and DAMP release were quantified by quantitative-PCR, ELISA, western blots, and reporter cells employing primary PMs, monocytes, and caspase-deficient THP-1 macrophages. Serum progranulin concentration was correlated with transplant-free survival in 77 patients with SBP.

RESULTS

E. coli ssDNA induced strong type-I IFN activity in PMs and monocytes, priming them for enhanced lipopolysaccharide-mediated tumor necrosis factor production without inducing toll-like receptor 4 tolerance. During in vitro macrophage bacterial infection, type-I IFN release aligned with upregulated expression of IFN-regulatory factors (IRF)1/2 and guanylate binding proteins (GBP)2/5. PMs upregulated inflammasome-associated proteins and type-I IFN upon E. coli ssDNA exposure and released interleukin-1β upon bacterial infection. Proteomic screening in mouse macrophages revealed progranulin release as being caspase-11-dependent during E. coli infection. PMs and THP-1 macrophages released significant amounts of progranulin when infected with S. aureus or E. coli via gasdermin D in a type-I IFN- and caspase-5-dependent manner. During SBP, PMs upregulated IRF1, GBP2/5 and caspase-5 and higher serum progranulin concentrations were indicative of lower 90-day transplant-free survival after SBP.

CONCLUSIONS

Type-I IFN shapes peritoneal immune responses and regulates caspase-5-mediated progranulin release during SBP.

IMPACT AND IMPLICATIONS

Patients with cirrhosis exhibit impaired immune responses and increased susceptibility to bacterial infections. This study reveals that type-I interferon responses, triggered by pathogen-associated molecular patterns, are crucial in regulating macrophage activation and priming them for inflammatory responses. Additionally, we elucidate the mechanisms by which type-I interferons promote the release of progranulin from macrophages during spontaneous bacterial peritonitis. Our findings enhance understanding of how bacterial translocation affects immune responses, identify novel biomarkers for inflammasome activation during infections, and point to potential therapeutic targets.

Liver diseases and hepatocellular carcinoma in the Asia-Pacific region: burden, trends, challenges and future directions

Globally, nearly half of deaths from cirrhosis and chronic liver diseases (CLD) and three-quarters of deaths from hepatocellular carcinoma (HCC) occur in the Asia-Pacific region. Chronic hepatitis B is responsible for the vast majority of liver-related deaths in the region. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common form of CLD, affecting an estimated 30% of the adult population. Compared with people of European descent, people from the Asia-Pacific region carry more genetic variants associated with MASLD and its progression. Alcohol is a fast-growing cause of CLD and HCC in Asia as a result of the rising per-capita consumption of alcohol. Drug-induced liver injury is under-recognized and probably has a high prevalence in this region. The epidemiological and outcome data of acute-on-chronic liver failure are heterogeneous, and non-unified definitions across regions contribute to this heterogeneity. CLDs are severely underdiagnosed, and effective treatments and vaccinations are underutilized. In this Review, we highlight trends in the burden of CLD and HCC in the Asia-Pacific region and discuss the rapidly changing aetiologies of liver disease. We examine the multiple gaps in the care cascade and propose mitigating strategies and future directions.

Liver-related mortality in homeless-experienced adults over a 16-year period

Homeless-experienced adults have higher liver-related mortality than the general population. The objective of our study was to examine temporal liver-related mortality trends and assess cause-specific liver-related mortality disparities in a large cohort of homeless-experienced adults. We linked a cohort of 60,092 adults who received care at Boston Health Care for the Homeless Program (BHCHP) from 2003-2017 to Massachusetts death occurrence files spanning 2003-2018. We evaluated temporal trends in age-standardized liver-related mortality rates in comparison to the MA population. We identified the leading causes of liver-related death aggregated across the study period and compared these cause-specific mortality rates to the general population, reporting standardized mortality rate ratios (SRRs). Of the 7,130 deaths in the cohort, 652 (9.1%) were liver-related. Among liver-related decedents, the mean age at death was 55.7 years (SD 8.3); 517 (79.2%) were male and 399 (61.2%) were White. Liver-related mortality decreased on average 3.5% annually (95% CI: -6.6%, -0.3%), though remained significantly higher than the MA population throughout the study period. Leading causes of liver-related death were cirrhosis (n=157, SRR 3.2 [95% CI: 3.2, 3.3]), liver cancer (n=148, SRR 2.4 [95% CI: 2.4, 2.5]), alcohol-related liver disease (n=140, SRR 4.4 [95% CI: 4.3, 4.6]), and viral hepatitis (n=99, SRR 7.2 [95% CI: 6.9, 7.6]).Liver-related deaths are an important contributor to excess mortality among homeless-experienced adults. Efforts to reduce this disparity should address alcohol use disorder and viral hepatitis given their substantial contribution to the disparity of mortality in this population.

A Case Report on Management of Liver Cirrhosis Using Ayurveda and Integrative Approach of Treatment

Background: Liver cirrhosis is an advanced stage of abnormal fibrogenesis of tissues that causes liver injuries. Though cirrhosis can be managed by etiological parameters, its long-term reversal is still a question. Ayurveda system of medicine diagnoses liver disease under "Kamala" and "Udara" with promising outcomes of treatment. This case series discusses three cases of liver cirrhosis where internal Ayurvedic medications and external therapies including "Panchakarma" (a treatment approach of detoxifying and rejuvenating) resulted in effective management of the disease. Case Presentation: Three cases of decompensated liver cirrhosis were treated at an Ayurveda hospital. Relevant examinations and investigations were done, and patients were monitored at regular intervals. Patients were treated with Ayurvedic therapies and were monitored for changes using standardized tools of assessment. Conclusion: In all three patients, there was an improvement in quality of life and a reduction in symptoms such as abdominal pain, transpyloric diameter, pedal oedema, and fatigue, as well as a significant reduction in liver function test parameters. Decompensated liver cirrhosis can be managed with an Ayurvedic treatment regimen that includes Ayurvedic medications, Panchakarma, along with a proper diet regimen with salt and fluid restrictions. This case series concludes that while cirrhosis is not completely reversible, fibrosis could be reversed. The support of modern medicine for monitoring and emergency care remains paramount. Furthermore, proper documentation of all the observations can help in assessing the outcomes of Ayurveda therapies and aid in developing integrative protocols for the management of liver cirrhosis in the future.

Spleen stiffness measurements during recompensation in patients with acutely decompensated liver cirrhosis: preliminary findings of a pilot study

Background

Acute decompensation (AD) in patients with liver cirrhosis is associated with a dramatic deterioration in prognosis. Immediate initiation of appropriate recompensation measures is essential to improve patient's outcome, although objective parameters for evaluating the success of recompensation are still lacking. Spleen stiffness measurements (SSM) have emerged as promising non-invasive tool to assess clinically significant portal hypertension (CSPH), which is the main driver of acute decompensation. However, while SSM accurately predicts CSPH and its complication, currently no data are available on its diagnostic performance during recompensation. This pilot-study aimed at evaluating changes in spleen stiffness following the initiation of recompensation measures in cirrhotic patients hospitalized due to AD.

Methods

In this prospective pilot-study, 60 patients with cirrhosis showing AD were included. Liver stiffness measurements (LSM) and SSM were performed on admission and repetitive SSM on day 3 and 5, respectivele, during recompensation measures. A cohort of patients (n = 10) with compensated cirrhosis served as control.

Results

A total of 36 data sets from the originally enrolled 60 patients were eligible for final analysis. On admission, patients with AD revealed a significantly increased spleen stiffness compared to the control group (70.51 vs. 29.06 kPa, p < 0.0001). Following the initiation of recompensation measures SSM revealed a significant reduction in spleen stiffness compared to the baseline assessment on day 3 (-18.5 kPa, -21.53%; p = 0.0002) with no further decrease on day 5 (-17.63 kPa, -21.23%; p = 0.0326).

Conclusion

Repetitive SSM seems to be a useful non-invasive clinical marker to assess the effectiveness of recompensation measures in cirrhotic patients with AD.

Metabolic factors for liver cirrhosis: A Mendelian randomization study

Liver cirrhosis is a chronic disease caused by long-term inflammation and fibrosis of the liver. Early identification and intervention in liver cirrhosis have become an important goal for researchers to explore the influence of some metabolic factors on the risk of liver cirrhosis in terms of genetic susceptibility. Data from genome-wide association studies (GWASs) of fourteen metabolic factors and liver cirrhosis were obtained from publicly available databases. To make the results more credible, we selected 2 GWASs for liver cirrhosis to be validated separately. The causal effect of metabolic factors on liver cirrhosis was assessed separately using 2-sample Mendelian Randomization (MR). The inverse variance weighted (IVW) method was used as the main analysis method. The present MR analysis confirmed that fasting insulin level (IVW-OR = 2.89, 95% CI: 1.36-6.15, P = .006) and ALT (IVW-OR = 1.42, 95% CI: 1.11-1.80, P = .004) were positively causally associated with the risk of liver cirrhosis, and there was a negative causal relationship between hypertension and the risk of liver cirrhosis (IVW-OR = 0.40, 95% CI: 0.23-0.72, P = .002) in 1 liver cirrhosis GWAS. In replication analysis, our MR proved the positive causal effect between ALT (IVW-OR = 2.09, 95% CI: 1.61-2.72, P < .001) and BMI (IVW-OR = 1.44, 95% CI: 1.17-1.77, P < .001) and the risk of liver cirrhosis. A causal relationship between other metabolic factors and the risk of liver cirrhosis could not be established in the current selection of data. Our MR study revealed a causal and positive association between ALT and the risk of liver cirrhosis, suggesting an important role of effective control of ALT in liver cirrhosis prevention. The causal relationship between thirteen other metabolic factors and the risk of liver cirrhosis remains to be further verified.

Ficus hirta Vahl. ameliorates liver fibrosis by triggering hepatic stellate cell ferroptosis through GSH/GPX4 pathway

ETHNOPHARMACOLOGICAL RELEVANCE

Ficus hirta Vahl., a traditional Chinese medicine commonly used in the Lingnan region, has been extensively used for liver disease treatment in China. Its notable antioxidant and anti-inflammatory properties have been reported in previous studies. However, its potential effect and underlying mechanism on liver fibrosis remains unclear.

AIM OF STUDY

This study was aimed to investigate the effect and its underlying mechanism of Ficus hirta Vahl on liver fibrosis in vitro and in vivo.

MATERIALS AND METHODS

The main components of Ficus hirta Vahl in blood were investigated by using UPLC-Q/TOF-MS/MS. Two animal models of liver fibrosis, the CCl4 and MCD induced mice, were used to assess the efficacy of Ficus hirta Vahl on liver fibrosis. Metabolomics was used to detect the level of metabolites in the serum of liver fibrosis mice after Ficus hirta Vahl treatment. Furthermore, the mechanism was validated in vitro using the human liver stellate cell line LX-2. The binding affinities of the active ingredients of Ficus hirta Vahl to the main targets of liver fibrosis were also determined. Finally, we identified the key active ingredients responsible for the treatment of liver fibrosis in vivo.

RESULTS

Fibrosis and inflammatory markers were significant down-regulation in both CCl4 and MCD induced liver fibrosis mice after Ficus hirta Vahl administration in a dose-dependent manner. We found that Ficus hirta Vahl may primarily exert its effect on liver fibrosis through the glutathione metabolic pathway. Importantly, the glutathione metabolic pathway is closely associated with ferroptosis, and our subsequent in vitro experiments provided evidence supporting this association. Ficus hirta Vahl was found to modulate the GSH/GPX4 pathway, ultimately leading to the amelioration of liver fibrosis. Moreover, using serum pharmacochemistry and molecular docking, we successfully identified apigenin as a probable efficacious monomer for the management of liver fibrosis and subsequently validated its efficacy in mice with CCl4-induced hepatic fibrosis.

CONCLUSION

Ficus hirta Vahl triggered the ferroptosis of hepatic stellate cell by regulating the GSH/GPX4 pathway, thereby alleviating liver fibrosis in mice. Moreover, apigenin is a key compound in Ficus hirta Vahl responsible for the effective treatment of liver fibrosis.

Qualitative service evaluation of a multimodal pilot service for early detection of liver disease in high-risk groups: 'Alright My Liver?'

OBJECTIVE

Liver disease is a growing cause of premature death in the UK. The National Health Service in England (NHS England) has funded regional early detection programmes through Community Liver Health Check pilots. 'Alright My Liver?' is Bristol and Severn's pilot service offering early detection of liver disease through screening events serving populations at risk, including people with a history of drug or alcohol use, type 2 diabetes and obesity. The service offers point-of-care testing for liver disease and a supported follow-up process.

METHODS

Semistructured interviews were conducted with 14 service users and six service providers over a 6-month period using diversity sampling. Topic guides encouraged discussion of experiences of the service as well as barriers and facilitators to accessing the service. Data were analysed using thematic analysis, and positive and negative comments pertaining to the service were collated in a 'table of changes' to inform optimisation.

RESULTS

Three main themes were identified: (1) motivations for engagement, (2) experience of the service and (3) health impacts. Key motivations for engagement were screening as a novel opportunity, a response to immediate health concerns or as reassurance. Service users commented on its convenience and that staff interactions were warm and informative. Some felt that follow-up could be more intensive. Impacts varied depending on perceived risk factors and screening results but generally involved stating a commitment to healthy lifestyle changes, including reducing alcohol use.

CONCLUSION

Targeted screening for liver disease in high-risk groups through this pilot service was deemed an appropriate and accessible intervention, with important optimisations identified.

Inflammasomes in chronic liver disease: Hepatic injury, fibrosis progression and systemic inflammation

Chronic liver disease leads to hepatocellular injury that triggers a pro-inflammatory state in several parenchymal and non-parenchymal hepatic cell types, ultimately resulting in liver fibrosis, cirrhosis, portal hypertension and liver failure. Thus, an improved understanding of inflammasomes - as key molecular drivers of liver injury - may result in the development of novel diagnostic or prognostic biomarkers and effective therapeutics. In liver disease, innate immune cells respond to hepatic insults by activating cell-intrinsic inflammasomes via toll-like receptors and NF-κB, and by releasing pro-inflammatory cytokines (such as IL-1β, IL-18, TNF-α and IL-6). Subsequently, cells of the adaptive immune system are recruited to fuel hepatic inflammation and hepatic parenchymal cells may undergo gasdermin D-mediated programmed cell death, termed pyroptosis. With liver disease progression, there is a shift towards a type 2 inflammatory response, which promotes tissue repair but also fibrogenesis. Inflammasome activation may also occur at extrahepatic sites, such as the white adipose tissue in MASH (metabolic dysfunction-associated steatohepatitis). In end-stage liver disease, flares of inflammation (e.g., in severe alcohol-related hepatitis) that spark on a dysfunctional immune system, contribute to inflammasome-mediated liver injury and potentially result in organ dysfunction/failure, as seen in ACLF (acute-on-chronic liver failure). This review provides an overview of current concepts regarding inflammasome activation in liver disease progression, with a focus on related biomarkers and therapeutic approaches that are being developed for patients with liver disease.

Gut Bacteria in Alcohol-Associated Liver Disease

Alcohol-associated liver disease (ALD) poses a significant global public health challenge, with high patient mortality rates and economic burden. The gut microbiome plays an important role in the onset and progression of alcohol-associated liver disease. Excessive alcohol consumption disrupts the intestinal barrier, facilitating the entry of harmful microbes and their products into the liver, exacerbating liver damage. Dysbiosis, marked by imbalance in gut bacteria, correlates with ALD severity. Promising microbiota-centered therapies include probiotics, phages, and fecal microbiota transplantation. Clinical trials demonstrate the potential of these interventions to improve liver function and patient outcomes, offering a new frontier in ALD treatment.

Tobacco is a Leading Risk Factor for Liver and Extrahepatic Cancers in Patients With Liver Cirrhosis: A Prospective Cohort Study

Background & aims

This study aims to assess the incidence and characteristics of all cancers, hepatocellular carcinoma (HCC), and extrahepatic cancers in patients with cirrhosis of various etiologies.

Methods

Prospective cohort study in patients with cirrhosis but no cancer, followed every 6-9 months through the HCC early detection program. Cancer incidence was compared with Spanish population data to calculate standardized incidence ratios (SIR), and cumulative incidence was calculated separately for cancer and competing events. Longitudinal outcomes were assessed with multivariate Fine-Gray and Cox regression models.

Results

A total of 215 patients (68.4% male, median age 61 years) were included. Cirrhotic etiology was alcohol (38%), hepatitis B or C virus infection (36%), alcohol plus hepatitis B or C virus infection (9%), and other causes (17%). Sixty percent were current or former smokers. Thirty-nine cancers were observed (56% liver cancer), while 3.3 were expected (SIR 11.7; 95% confidence interval [CI] 8.6-16.1). Ten (4.6%) patients were censored for liver transplantation and 34 (15.8%) for death, constituting relevant competing risks. Smoking was significantly associated with overall cancer incidence (smokers: subdistribution hazard ratio [SHR] 3.14, 95% CI 1.33-7.38; former smokers: SHR 2.54, 95% CI 1.08-5.98). In the multivariable regression analysis, viral etiology, Child-Pugh score (B or C versus A), and smoking were associated with liver cancer, and smoking with extrahepatic cancer.

Conclusions

Patients with cirrhosis have an 11-fold risk of cancer compared to the general population. Risk is increased in liver and non-liver cancers. Active surveillance of any type of cancer and smoking cessation interventions are needed in these patients.

Clinical Outcomes of Transjugular Intrahepatic Portosystemic Shunt Among Cirrhosis Patients With Recurrent Esophageal Variceal Bleeding

Background Transjugular intrahepatic portosystemic shunt (TIPS) has been shown to reduce the risk of rebleeding among patients with recurrent esophageal variceal bleeding. However, the impact of TIPS on survival remains uncertain. This study took on this challenge to determine if TIPS has any impact on all-cause inpatient mortality during the hospitalization in which it is performed and if it impacts all-cause 30-day readmission rates when compared to patients who only undergo esophageal variceal banding (EVB) for recurrent esophageal variceal bleeding. Methods This was a retrospective cohort study using the Healthcare Cost and Utilization Project - National Readmission Database 2019. All adult patients who had a diagnosis of cirrhosis, were hospitalized once for esophageal variceal bleeding requiring EVB in 2019, and then were hospitalized again later in the year for recurrent esophageal variceal bleeding requiring either TIPS or EVB were included. This second hospitalization in which patients either received TIPS or EVB only was considered as the index hospitalization. Patients with missing data and patients who were discharged in December were excluded. The primary outcome was all-cause 30-day readmission rates among patients who either received TIPS or EVB only. The secondary outcomes included: (i) incidence of all-cause inpatient mortality; and (ii) length of hospital stay during index hospitalization. Patients who underwent TIPS were matched with patients who underwent EVB only on age, sex, and baseline comorbidities. After propensity score matching, survival analysis was performed to compare the all-cause 30-day readmission rates after the index hospitalization, between patients who either received TIPS or EVB only during the index hospitalization. χ2 test was used to compare the inpatient mortality. As the data did not have a normal distribution, the Wilcoxon signed-rank test was used to compare the length of index hospitalization between patients who either received TIPS or EVB only. The alpha criterion was set at 0.05 for all statistical tests. Results This study found no difference in all-cause 30-day readmission rates between patients who underwent either TIPS or EVB only for recurrent esophageal variceal bleeding (hazard ratio: 1.24, 95%CI: 0.73-2.12, P = 0.4). In the exploratory analysis, it was noted that the rate of recurrent esophageal variceal bleeding, among patients who were readmitted within 30 days was lower in the TIPS group (13.3%) when compared to the EVB group (50%) with a risk ratio of 0.27 (95%CI: 0.10-0.72, P = 0.003). Although it was not statistically significant, the inpatient mortality rate during the index hospitalization appeared to be lower in the TIPS group when compared to the EVB group (4.2% vs 10.08%, respectively). Patients who underwent TIPS were hospitalized three days longer than patients who underwent EVB only. Conclusion TIPS does not reduce all-cause 30-day readmission rates but is associated with reduced 30-day readmission rates secondary to recurrent esophageal variceal bleeding. TIPS shows a modest survival advantage during index hospitalization when compared to EVB only.

Prognostic impact of age on outcomes of hepatic decompensation in patients with compensated cirrhosis (CHESS2102): an international, multicenter cohort study

Baveno VII criteria (B7C) and Baveno VI criteria (B6C) have been widely used to estimate the risk of hepatic decompensation. However, the impact of age on these criteria warrants further investigation. The international, multicenter cohort study included 1138 patients with compensated cirrhosis (median follow-up of 40.6 months), aiming to evaluate the value of age in predicting hepatic decompensation. We identified age as an independent predictor of hepatic decompensation, with 60 years determined as the optimal cut-off value. The occurrence of decompensation was 18.7% and 6.7% in the older (age ≥60 years) and younger (age <60 years) groups, respectively (p < 0.001). We subsequently integrated age into the existing Baveno criteria. In patients not meeting Baveno criteria (defined as not meeting B6C or B7C), the older group exhibited a significantly elevated risk of decompensation compared to the younger group (p < 0.05). However, no significant difference was observed between the older and younger groups in patients meeting Baveno criteria (p > 0.05). In conclusion, our study demonstrated that integrating age into the Baveno criteria could enhance the assessment of hepatic decompensation. Age should be considered before discharging patients with compensated cirrhosis from the surveillance of hepatic decompensation.

Epidemiology of Alcohol-Associated Liver Disease Including Increasing Burden in Young Adults and Females Especially Since Covid-19 Pandemic

Alcohol-associated liver disease (ALD) was already on the rise globally when the advent of coronavirus disease 2019 further accelerated this trend. ALD has emerged as the leading cause for liver transplantation in the United States. The pandemic has not only intensified the prevalence of ALD but has also highlighted significant disparities in its impact, particularly, among young adults and women. This review aims to dissect the complex landscape of ALD, focusing on gender, race, and emerging risk factors in the context of the current global health crisis.

Integrated Multidisciplinary Care Model to Manage the Dual Pathology of Alcohol Use Disorder and of Liver Disease

Alcohol-associated liver disease (ALD) is the most common cause of liver disease and an indication for liver transplantation. Identification of ALD at an earlier stage and treatment of concomitant alcohol use disorder (AUD) could potentially prevent or delay the progression to advanced stages of ALD like alcohol-associated cirrhosis and alcohol-associated hepatitis. However, screening for alcohol use is often not performed and treatment of AUD is rarely administered in ALD patients, due to several barriers at the level of patients, clinicians, and administrative levels.

Diabetes risk reduction diet and risk of liver cancer and chronic liver disease mortality: A prospective cohort study

BACKGROUND

We aimed to prospectively evaluate the association between a diabetes risk reduction diet (DRRD) score and the risk of liver cancer development and chronic liver disease-specific mortality.

METHODS

We included 98,786 postmenopausal women from the Women's Health Initiative-Observational Study and the usual diet arm of the Diet Modification trial. The DRRD score was derived from eight factors: high intakes of dietary fiber, coffee, nuts, polyunsaturated fatty acids, low intakes of red and processed meat, foods with high glycemic index, sugar-sweetened beverages (SSBs), and trans fat based on a validated Food-Frequency Questionnaire administered at baseline (1993-1998). Multivariable hazard ratios (HRs) and 95% confidence intervals (CIs) for liver cancer incidence and chronic liver disease mortality were estimated using Cox proportional hazards regression models.

RESULTS AND CONCLUSION

After a median follow-up of 22.0 years, 216 incident liver cancer cases and 153 chronic liver disease deaths were confirmed. A higher DRRD score was significantly associated with a reduced risk of developing liver cancer (HRTertile 3 vs. Tertile 1 = 0.69; 95% CI: 0.49-0.97; Ptrend = 0.03) and chronic liver disease mortality (HRT3 vs. T1 = 0.54; 95% CI: 0.35-0.82; Ptrend = 0.003). We further found inverse associations with dietary fiber and coffee, and positive associations with dietary glycemic index, SSBs, and trans fat. A higher DRRD score was associated with reduced risk of developing liver cancer and chronic liver disease mortality among postmenopausal women.

Spatiotemporal trends of Type 2 diabetes due to low physical activity from 1990 to 2019 and forecasted prevalence in 2050: A Global Burden of Disease Study 2019

BACKGROUND

Type 2 diabetes mellitus (T2DM) poses a major global health burden, yet epidemiological research on low physical activity's (LPA) impact is limited. This study examines LPA's global effect on T2DM.

METHODS

Analyzing Global Burden of Disease Database (GBD) 2019, we explored LPA-attributable T2DM deaths and Disability-Adjusted Life Years (DALYs) from 1990 to 2019, stratified by year, gender, country, and SDI regions. Estimated Annual Percentage Change (EAPC) assessed trends, and Bayesian models predicted future patterns.

RESULTS

In 2019, LPA accounted for a substantial 8.5% of T2DM deaths and 6.9% of DALYs, representing a noticeable rise since 1990. Age-standardized mortality rates (ASMR) and disability-adjusted life years rates (ASDR) increased globally, particularly in low Socio-Demographic Index (SDI) regions. High and high-middle SDI regions saw a decrease in ASMR, while all regions generally saw an upward trend in ASDR. Projections for 2050 suggest a declining ASMR but an increasing ASDR, indicating a continuing burden of T2DM despite potential mortality reductions.

CONCLUSION

LPA significantly impacts T2DM, particularly in low SDI regions. Promotion of physical activity is crucial to reduce this burden, particularly in regions where the disease's impact is most severe.

New insights into potential biomarkers and their roles in biological processes associated with hepatitis C-related liver cirrhosis by hepatic RNA-seq-based transcriptome profiling

Chronic hepatitis C virus infection is a major cause of mortality due to liver cirrhosis globally. Despite the advances in recent therapeutic strategies, there is yet a high burden of HCV-related cirrhosis worldwide concerning low coverage of newly developed antiviral therapies, insufficient validity of the current diagnostic methods for cirrhosis, and incomplete understanding of the pathogenesis in this stage of liver disease. Hence we aimed to clarify the molecular events in HCV-related cirrhosis and identify a liver-specific gene signature to potentially improve diagnosis and prognosis of the disease. Through RNA-seq transcriptome profiling of liver samples of Iranian patients with HCV-related cirrhosis, the differentially expressed genes (DEGs) were identified and subjected to functional annotation including biological process (BP) and molecular function (MF) analysis and also KEGG pathway enrichment analysis. Furthermore, the validation of RNA-seq data was investigated for seven candidate genes using qRT-PCR. Moreover, the diagnostic and prognostic power of validated DEGs were analyzed in both forms of individual DEG and combined biomarkers through receiver operating characteristic (ROC) analysis. Finally, we explored the pair-wise correlation of these six validated DEGs in a new approach. We identified 838 significant DEGs (padj ˂0.05) enriching 375 and 15 significant terms subjected to BP and MF, respectively (false discovery rate ˂ 0.01) and 46 significant pathways (p-value ˂ 0.05). Most of these biological processes and pathways were related to inflammation, immune responses, and cellular processes participating somewhat in the pathogenesis of liver disease. Interestingly, some neurological-associated genes and pathways were involved in HCV cirrhosis-related neuropsychiatric disorders. Out of seven candidate genes, six DEGs, including inflammation-related genes ISLR, LTB, ZAP70, KLRB1, and neuronal-related genes MOXD1 and Slitrk3 were significantly confirmed by qRT-PCR. There was a close agreement in the expression change results between RNA-seq and qRT-PCR for our candidate genes except for SAA2-SAA4 (P= 0.8). High validity and reproducibility of six novel DEGs as diagnostic and prognostic biomarkers were observed. We also found several pair-wise correlations between validated DEGs. Our findings indicate that the six genes LTB, ZAP70, KLRB1, ISLR, MOXD1, and Slitrk3 could stand as promising biomarkers for diagnosing of HCV-related cirrhosis. However, further studies are recommended to validate the diagnostic potential of these biomarkers and evaluate their capability as targets for the prevention and treatment of cirrhosis disease.

Changing global epidemiology of chronic hepatitis C virus-related outcomes from 2010 to 2019: cirrhosis is the growing burden of hepatitis C virus-related disease

BACKGROUND

Chronic infection with hepatitis C virus (HCV) has a long-term impact on hepatic consequences. A comprehensive evaluation of the global burden of HCV-related health outcomes can help to develop a global HCV prevention and treatment program.

METHODS

We used the 2019 Global Burden of Disease (GBD) Study to comprehensively investigate burden and temporal trends in incidence, mortality and disability-adjusted life-years (DALYs) of HCV-related diseases, including liver cancer and cirrhosis and other liver diseases across 264 countries and territories from 2010 to 2019.

RESULTS

Globally, there were 152 225 incident cases, 141 811 deaths and approximately 2.9 million DALYs because of HCV-related liver cancer, and 551 668 incident cases, 395 022 deaths and about 12.2 million DALYs because of HCV-related cirrhosis in 2019. Worldwide, during the 2010-2019 period, liver cancer incidence declined, however, there was a 62% increase in cirrhosis incidence. In 2019, the Eastern Mediterranean was the region with the highest rates of incidence and mortality of both liver cancer and cirrhosis. Africa was the region with the fastest-growing trend of incidence of cirrhosis in the 2010-2019 period [annual percentage change (APC) = 2.09, 95% confidence interval (CI): 1.93-2.25], followed by the Western Pacific region (APC = 1.17, 95% CI: 1.09-1.22). Americas were the only region observing increased trends in liver cancer and cirrhosis mortality (APC = 0.70 and 0.12, respectively). We identified three patterns of temporal trends of mortality rates of liver cancer and cirrhosis in countries that reported HCV treatment rates.

CONCLUSION

Urgent measures are required for diagnosis, treatment and research on HCV-related cirrhosis at global, regional and country levels, particularly in Africa, the Western Pacific and the Eastern Mediterranean.

The burden of cirrhosis and other chronic liver disease in the middle east and North Africa (MENA) region over three decades

BACKGROUND

Cirrhosis comprises a significant health challenge in the Middle East and North African (MENA) region impacting healthcare systems and communities. This study sought to investigate trends in the burden of cirrhosis and other chronic liver disease, different etiologies, deaths, and the disability burden utilizing data from the Global Burden of Disease (GBD) database.

METHODS

Analyzing epidemiological trends from 1990 to 2021 across 21 MENA countries, this research utilized data on age-standardized incidence rates (ASIR), age-standardized death rates, and age-standardized disability-adjusted life years (DALYs) to evaluate the burden of cirrhosis and other chronic liver disease. The study also examined national variations and sociodemographic relationships.

RESULTS

The study identified a 114.9% increase in cirrhosis and other chronic liver disease incidence within the MENA region between 1990 and 2021, with 7,344,030 incident cases reported in 2021. The ASIR showed a steeper rise in females (9.6%) compared to males (7.0%). Etiology-specific analysis revealed an increase in the ASIR for MASLD related cirrhosis and other chronic liver disease by 22.2%, while those due to alcohol as well as hepatitis B and C decreased by 28.1%, 59.3%, and 30%, respectively. Despite the rising incidence, overall age-standardized death rates across all etiologies decreased by 54.3%, with DALYs showing a 51.4% decrease during the same period. Country-specific trends varied significantly, with Oman recording the highest annual ASIR increase (0.64%), and Qatar observing the most substantial annual reduction in age-standardized death rates (-2.88%).

CONCLUSION

The study highlights evolving trends in cirrhosis and other chronic liver disease within the MENA region, emphasizing the necessity for comprehensive, etiology, and gender-specific interventions. Despite an increasing incidence, the observed improvements in mortality rates and age-standardized disability burden indicate progress in public health efforts to mitigate cirrhosis's impact. These findings point to the complex nature of cirrhosis outcomes and the urgent need for tailored strategies to manage its increasing burden effectively.
