UNASSIGNED: Metabolic-associated fatty liver disease (MAFLD) is a leading cause of chronic liver disease. Nowadays, the prevalence of MAFLD in Mexico is unknown with no screening point-of-care tools. We aimed to estimate the prevalence of MAFLD in Mexico and to develop a score for MAFLD screening.
UNASSIGNED: We conducted a cross-sectional study in 5 Mexican states, including adult subjects evaluated in checkup campaigns. Subjects underwent a liver ultrasound to look for hepatic steatosis. Based on the most clinically relevant variables associated with MAFLD, we developed the MAFLD-screening score (MAFLD-S). Discrimination and calibration of the score were evaluated using the area under the ROC curve and observed vs predicted plots, respectively.
UNASSIGNED: We included 3357 participants (60% female, mean age 47 ± 12 years). Fifty-two percent had hepatic steatosis, and 47% met MAFLD criteria. Subjects with MAFLD were older (48 ± 11 vs 45 ± 13 years, P < .001), were more frequently males (43% vs 36%, P < .001), and had a higher body mass index (31.6 + 4.9 vs 25.6 + 3.8 kg/m2, P < .001) than subjects without MAFLD. The MAFLD-S includes age, body mass index, gender, diabetes, hypertension, and dyslipidemia and has an area under the curve of 0.852, 95% CI = 0.828-0.877, with a sensitivity of 78.8% and a specificity of 82.8% for the optimal cutoff. Using data from the National Health and Nutrition Survey 2018-2019, we predicted a MAFLD national prevalence of 49.6%.
UNASSIGNED: Nearly half of the Mexican population has MAFLD, representing a present and future challenge. With external validation, the MAFLD-S could be a valuable and practical screening tool.

Since the start of the pandemic, considerable advancements have been made in our understanding of the effects of SARS-CoV-2 infection and the associated COVID-19 on the hepatic system. There is a broad range of clinical symptoms for COVID-19. It affects multiple systems and has a dominant lung illness depending on complications. The progression of COVID-19 in people with pre-existing chronic liver disease (CLD) has also been studied in large multinational groups. Notably, SARS-CoV-2 infection is associated with a higher risk of hepatic decompensation and death in patients with cirrhosis. In this review, the source, composition, mechanisms, transmission characteristics, clinical characteristics, therapy, and prevention of SARS-CoV-2 were clarified and discussed, as well as the evolution and variations of the virus. This review briefly discusses the causes and effects of SARS-CoV-2 infection in patients with CLD. As part of COVID-19, In addition, we assess the potential of liver biochemistry as a diagnostic tool examine the data on direct viral infection of liver cells, and investigate potential pathways driving SARS-CoV-2-related liver damage. Finally, we explore how the pandemic has had a significant impact on patient behaviors and hepatology services, which may increase the prevalence and severity of liver disease in the future. The topics encompassed in this review encompass the intricate relationships between SARS-CoV-2, liver health, and broader health management strategies, providing valuable insights for both current clinical practice and future research directions.

Objectives: Congestive hepatopathy is a significant complication for children suffering from right-sided heart disease (RHD). We hypothesize that hospitalized pediatric patients with ascites will have congestive hepatopathy leading to advanced liver disease if their cardiac condition is RHD versus non-right-sided heart disease (NRHD). Methods: This is a retrospective cohort study of pediatric patients who presented with an ascites diagnosis (ICD-10 R18) and at least one cardiac diagnosis. Patient demographics, past medical history, laboratory values, imaging results, calculated clinical scores (e.g., APRI, FIB-4), treatment, length of stay (LOS), and death at hospital discharge were analyzed. Results: Of the 136 patients with ascites, 21 patients presented with a primary cardiac disease (12 in RHD and 9 in NRHD). Of these patients, eight (38%) were female, and nine (43%) were White, seven (33%) were Black, and five (24%) were unknown. The RHD group had a mean age of 5.1 Y (vs. 9.5 Y in NRHD). The mean APRI score in RHD patients was 2.87, and it was 0.85 in NRDH. Treatments were similar, with most patients requiring diuretics (11 RHD (92%) vs. 8 NRDH (89%)); 5 RHD (42%) vs. 4 NRDH (44%) required inotropic support. RHD patients had a longer LOS, with an average of 92 days vs. 52 days for NRDH patients. Overall, each group had one death at discharge (8% RHD vs. 11% NRDH). Conclusions: In the realm of children with ascites, the subset grappling with congestive heart disease paints a unique picture. In this context, ascites stands as an elusive predictor of liver decompensation, defying conventional diagnostic pathways.

UNASSIGNED: Abnormal liver biochemistry (ALB) is common among patients with COVID-19 infection due to various factors. It is uncertain if it persists after the acute infection. We aimed to investigate this.
UNASSIGNED: A multicenter study of adult patients hospitalized for COVID-19 infection, with at least a single abnormal liver function test, was conducted. Detailed laboratory and imaging tests, including transabdominal ultrasound and FibroScan, were performed at assessment and at 6-month follow-up after hospital discharge.
UNASSIGNED: From an initial cohort of 1246 patients who were hospitalized, 731 (58.7%) had ALB. A total of 174/731 patients fulfilled the inclusion criteria with the following characteristics: 48.9% patients had severe COVID-19; 62.1% had chronic liver disease (CLD); and 56.9% had metabolic-associated fatty liver disease (MAFLD). ALB was predominantly of a mixed pattern (67.8%). Among those (55.2%) who had liver injury (aspartate aminotransferase/alanine aminotransferase >3 times the upper limit of normal, or alkaline phosphatase/γ-glutamyl transferase/bilirubin >2 times the upper limit of normal), a mixed pattern was similarly predominant. Approximately 52.3% had normalization of the liver lunction test in the 6-month period post discharge. Patients with persistent ALB had significantly higher mean body mass index (BMI) and serum low-density lipoprotein (LDL), higher rates of MAFLD and CLD, higher mean liver stiffness measurement and continuous attenuated parameter score on FibroScan, and higher rates of liver injury on univariate analysis. Multivariate analysis was not statistically significant.
UNASSIGNED: Approximately 47.7% of COVID-19 patients were found to have persistent ALB up to 6 months following the acute infection, and it was associated with raised BMI, elevated serum LDL, increased rates of MAFLD and CLD, and higher rates of liver injury on univariate analysis, but not on multivariate analysis.

Introduction Chronic liver disease progression leads to liver fibrosis/cirrhosis. Transient Elastography is used for staging liver fibrosis but ascites, obesity, and operator experience limit its applicability. In this study, we compared various non-invasive serum indices in predicting fibrosis in chronic liver disease patients. Materials and methods A total of 142 cases of confirmed Chronic Liver Disease were included. Quantitative determination of liver stiffness by Transient Elastography and relevant blood investigations was done. We compared the liver stiffness measurement by Transient Elastography and fibrosis indices, i.e., Aspartate Transaminase (AST) to Alanine Transaminase (ALT) Ratio (AAR), AST to Platelet Ratio Index (APRI), Fibrosis Index (FI), Fibrosis-4 (FIB-4) Index, Age-Platelet Index (API), Pohl score, and Fibrosis Cirrhosis Index (FCI) with Novel Fibrosis Index (NFI), to predict liver fibrosis stages. Results The optimum cutoff of NFI for the F4 stage was ≥ 6670 with a sensitivity of 75.8% and specificity of 81.8%, for the F3 stage was ≥ 2112 with a sensitivity of 63.6% and specificity of 72.7%, and for the F2 stage was ≥ 1334 with a sensitivity of 100% and specificity of 56.3%. The NFI had the maximum area under the curve compared to other indices in predicting fibrosis stages. Conclusion The Novel Fibrosis Index was the best in predicting fibrosis stages in Chronic Liver Disease patients, with good performance in predicting the F4 stage.

UNASSIGNED: To assess economic and social issues faced by cirrhotic patients & its financial burden for developing nations like Pakistan.
UNASSIGNED: This cross-sectional study was carried out at the Department of Gastroenterology & Hepatology, Shaikh Zayed Hospital, Lahore, Pakistan during the period between July & December 2019. Patients with liver cirrhosis were recruited and information regarding disease, financial status, treatment expenses & dependency was recorded.
UNASSIGNED: A total of 450 patients were recruited, 272 (60%) were males & 178 (40%) were females, with mean age 55.4±6.2 years. HCV was cause of cirrhosis in 86% of cases, 65% were diagnosed incidentally and 39.6% were illiterate. About 82.7% were urban while only 28.7% own their own home. Co-morbid conditions including diabetes, hypertension & ischemic heart disease were present in 54% of cases. Monthly income was UNASSIGNED: Our study shows the financial difficulties & dependency faced by patients with liver cirrhosis. Aggressive national screening is required to discover infected patients before cirrhosis develops.

Patients with liver cirrhosis, due to their weakened innate and adaptive immunity, are more prone to frequent and severe vaccine-preventable infections. Moreover, impaired adaptive immunity results in a limited antibody response to vaccines. Despite this suboptimal antibody response, vaccines have proven to be very effective in reducing severe outcomes and deaths in these patients. In the Western world, regulatory authorities and scientific liver societies (e.g., AASLD and EASL) have recommended vaccinations for cirrhotic patients. However, despite these strong recommendations, vaccine coverage remains suboptimal. Improving vaccine effectiveness and safety information, providing comprehensive counseling to patients, fact-checking to combat fake news and disinformation and removing barriers to vaccination for disadvantaged individuals may help overcome the low coverage rate. In view of this, vaccines should be administered early in the course of chronic liver diseases, as their efficacy declines with the increasing severity of the disease.

Background: Liver cirrhosis presents significant challenges in the pediatric population due to a complex interplay of etiological factors, clinical manifestations, and limited therapeutic options. The leading contributors to cirrhosis among pediatric patients are chronic cholestasis, metabolic disorders present from birth, and long-term hepatitis. Materials and method: Our narrative review aimed to synthesize literature data on the etiology, clinical picture, diagnostic techniques, optimal management of complications, and timely transplantation. Results: The epidemiology of liver cirrhosis in pediatric patients is evolving. The introduction of a universal vaccination and effective long-term viral suppression in viral hepatitis have significantly decreased complications rates. Liver transplantation programs worldwide have also improved the management of cirrhosis complications. Conclusions: Early diagnosis, comprehensive management strategies, and advancements in treatment modalities are critical for improving outcomes. Understanding these differences is crucial in providing age-appropriate care and support for those affected by cirrhosis.

BACKGROUND: Liver fibrosis has been recognized as a long-term morbidity associated with Fontan circulation (Fontan-associated liver disease, FALD). The pathophysiology of FALD is not completely understood and abnormal flow dynamics may be associated with this condition. Liver hemodynamics can be quantitatively evaluated with four-dimensional phase-contrast flow magnetic resonance imaging (4D PC flow MRI). The study aimed to evaluate suitability of liver 4D PC flow MRI in Fontan patients and relate flow measurements to normal values and FALD severity.
METHODS: Twenty-two Fontan patients were examined by 4D PC flow MRI at 1.5 Tesla to assess mesenteric, portal, splenic, and hepatic venous blood flow. Severity of FALD was graded based on routine screening, including abdominal ultrasound and laboratory tests.
RESULTS: Median age was 18.5 (interquartile range, IQR 15.5-20.2) years. FALD was graded as \"none or mild\" in 16 and as \"moderate to severe\" in six cases. Ten patients presented at least one feature of portal hypertension (ascites, splenomegaly, or thrombocytopenia). For the entire cohort, blood flow in the superior mesenteric, splenic, and portal vein was lower than reported in the literature. No significant differences were observed in relation to FALD severity. Features of portal hypertension were associated with a higher splenic vein blood flow (0.34 ± 0.17 vs. 0.20 ± 0.07 l/min, p = 0.046). Splenic vein blood flow was negatively correlated to platelet count (r = -0.590, p = 0.005).
CONCLUSIONS: 4D PC flow MRI appears suitable to assess liver hemodynamics in Fontan patients and integration into clinical follow-up might help to improve our understanding of FALD.

UNASSIGNED: It is unclear to what extent lifestyle and genetic factors affect the incidence of chronic liver disease (CLD) in the general population and if lifestyle affects CLD independently of underlying cardiometabolic perturbations and genetic predisposition.
UNASSIGNED: We examined 27,991 men and women aged 44-73 years from the Malmö Diet and Cancer Study recruited between 1991-1996 and followed until the end of 2020 using registry linkage (median follow-up time 25.1 years; 382 incident first-time CLD events). Associations between cardiometabolic factors, polygenic risk scores (PRSs), and lifestyle factors in relation to CLD were examined using multivariable Cox proportional hazards regression models.
UNASSIGNED: The incidence of CLD increased with number of cardiometabolic risk factors (the hazard ratio per each additional cardiometabolic risk factor was 1.33; 95% CI 1.21-1.45; p = 5.1 x 10-10). Two novel PRSs for metabolic dysfunction-associated steatotic liver disease and a PRS for cirrhosis were associated with higher risk of CLD but provided marginal predictive utility on top of other risk factors and compared to the PNPLA3 rs738409 genetic variant. An unhealthy lifestyle (high alcohol intake, current smoking, physical inactivity and unhealthy diet) markedly increased the risk of CLD (hazard ratio 3.97, 95% CI 2.59-6.10). Observed associations between examined lifestyle factors and CLD were largely independent of cardiometabolic perturbations and polygenic risk.
UNASSIGNED: We confirmed the importance of cardiometabolic dysfunction in relation to risk of CLD in the general population. Lifestyle risk factors were shown to be independently associated with CLD and added predictive information on top of cardiometabolic risk factors. Information on the polygenic risk of liver disease does not currently improve the prediction of CLD in the general population.
UNASSIGNED: This large population-based prospective study suggests largely independent roles of cardiometabolic, lifestyle, and genetic risk factors in the development of chronic liver disease. Findings strengthen the evidence base for a beneficial effect of modification of high-risk lifestyle behaviors in the primary prevention of chronic liver disease in the general population.
