RESUMEN

BACKGROUND: Effective treatments for patients with primary biliary cholangitis are limited. Seladelpar, a peroxisome proliferator-activated receptor delta agonist, has potential benefits. METHODS: In this phase 3, 12-month, double-blind, placebo-controlled trial, we randomly assigned (in a 2:1 ratio) patients who had had an inadequate response to or who had a history of unacceptable side effects with ursodeoxycholic acid to receive oral seladelpar at a dose of 10 mg daily or placebo. The primary end point was a biochemical response, which was defined as an alkaline phosphatase level less than 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level at month 12. Key secondary end points were normalization of the alkaline phosphatase level at month 12 and a change in the score on the pruritus numerical rating scale (range, 0 [no itch] to 10 [worst itch imaginable]) from baseline to month 6 among patients with a baseline score of at least 4 (indicating moderate-to-severe pruritus). RESULTS: Of the 193 patients who underwent randomization and treatment, 93.8% received ursodeoxycholic acid as standard-of-care background therapy. A greater percentage of the patients in the seladelpar group than in the placebo group had a biochemical response (61.7% vs. 20.0%; difference, 41.7 percentage points; 95% confidence interval [CI], 27.7 to 53.4, P<0.001). Normalization of the alkaline phosphatase level also occurred in a greater percentage of patients who received seladelpar than of those who received placebo (25.0% vs. 0%; difference, 25.0 percentage points; 95% CI, 18.3 to 33.2, P<0.001). Seladelpar resulted in a greater reduction in the score on the pruritus numerical rating scale than placebo (least-squares mean change from baseline, -3.2 vs. -1.7; least-squares mean difference, -1.5; 95% CI, -2.5 to -0.5, P = 0.005). Adverse events were reported in 86.7% of the patients in the seladelpar group and in 84.6% in the placebo group, and serious adverse events in 7.0% and 6.2%, respectively. CONCLUSIONS: In this trial involving patients with primary biliary cholangitis, the percentage of patients who had a biochemical response and alkaline phosphatase normalization was significantly greater with seladelpar than with placebo. Seladelpar also significantly reduced pruritus among patients who had moderate-to-severe pruritus at baseline. The incidence and severity of adverse events were similar in the two groups.

RESUMEN

BACKGROUND AND AIMS: Antifibrotic trials rely on conventional pathology despite recognized limitations. We compared single-fiber digital image analysis with conventional pathology to quantify the antifibrotic effect of Aramchol, a stearoyl-CoA desaturase 1 inhibitor in development for metabolic dysfunction-associated steatohepatitis. APPROACH AND RESULTS: Fifty-one patients with metabolic dysfunction-associated steatohepatitis enrolled in the open-label part of the ARMOR trial received Aramchol 300 mg BID and had paired pre-post treatment liver biopsies scored by consensus among 3 hepatopathologists, and separately assessed by a digital image analysis platform (PharmaNest) that generates a continuous phenotypic Fibrosis Composite Severity (Ph-FCS) score. Fibrosis improvement was defined as: ≥1 NASH Clinical Research Network (NASH-CRN) stage reduction; "improved" by ranked pair assessment; reduction in Ph-FCS ("any" for ≥0.3 absolute reduction and "substantial" for ≥25% relative reduction). Fibrosis improved in 31% of patients (NASH-CRN), 51% (ranked pair assessment), 74.5% (any Ph-FCS reduction), and 41% (substantial Ph-FCS reduction). Most patients with stable fibrosis by NASH-CRN or ranked pair assessment had a Ph-FCS reduction (a third with substantial reduction). Fibrosis improvement increased with treatment duration: 25% for <48 weeks versus 39% for ≥48 weeks by NASH-CRN; 43% versus 61% by ranked pair assessment, mean Ph-FCS reduction -0.54 (SD: 1.22) versus -1.72 (SD: 1.02); Ph-FCS reduction (any in 54% vs. 100%, substantial in 21% vs. 65%). The antifibrotic effect of Aramchol was corroborated by reductions in liver stiffness, Pro-C3, and enhanced liver fibrosis. Changes in Ph-FCS were positively correlated with changes in liver stiffness. CONCLUSIONS: Continuous fibrosis scores generated in antifibrotic trials by digital image analysis quantify antifibrotic effects with greater sensitivity and a larger dynamic range than conventional pathology.

RESUMEN

BACKGROUND & AIMS: Patients with fatty liver disease may experience stigma from the disease or comorbidities. In this cross-sectional study, we aimed to understand stigma among patients with nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH) and healthcare providers. METHODS: Members of the Global NASH Council created two surveys about experiences/attitudes toward NAFLD and related diagnostic terms: a 68-item patient and a 41-item provider survey. RESULTS: Surveys were completed by 1,976 patients with NAFLD across 23 countries (51% Middle East/North Africa [MENA], 19% Europe, 17% USA, 8% Southeast Asia, 5% South Asia) and 825 healthcare providers (67% gastroenterologists/hepatologists) across 25 countries (39% MENA, 28% Southeast Asia, 22% USA, 6% South Asia, 3% Europe). Of all patients, 48% ever disclosed having NAFLD/NASH to family/friends; the most commonly used term was "fatty liver" (88% at least sometimes); "metabolic disease" or "MAFLD" were rarely used (never by >84%). Regarding various perceptions of diagnostic terms by patients, there were no substantial differences between "NAFLD", "fatty liver disease (FLD)", "NASH", or "MAFLD". The most popular response was being neither comfortable nor uncomfortable with either term (56%-71%), with slightly greater discomfort with "FLD" among the US and South Asian patients (47-52% uncomfortable). Although 26% of patients reported stigma related to overweight/obesity, only 8% reported a history of stigmatization or discrimination due to NAFLD. Among providers, 38% believed that the term "fatty" was stigmatizing, while 34% believed that "nonalcoholic" was stigmatizing, more commonly in MENA (43%); 42% providers (gastroenterologists/hepatologists 45% vs. 37% other specialties, p = 0.03) believed that the name change to metabolic dysfunction-associated steatotic liver disease (or MASLD) might reduce stigma. Regarding the new nomenclature, the percentage of providers reporting "steatotic liver disease" as stigmatizing was low (14%). CONCLUSIONS: The perception of NAFLD stigma varies among patients, providers, geographic locations and sub-specialties. IMPACT AND IMPLICATIONS: Over the past decades, efforts have been made to change the nomenclature of nonalcoholic fatty liver disease (NAFLD) to better align with its underlying pathogenetic pathways and remove any potential stigma associated with the name. Given the paucity of data related to stigma in NAFLD, we undertook this global comprehensive survey to assess stigma in NAFLD among patients and providers from around the world. We found there is a disconnect between physicians and patients related to stigma and related nomenclature. With this knowledge, educational programs can be developed to better target stigma in NAFLD among all stakeholders and to provide a better opportunity for the new nomenclature to address the issues of stigma.

RESUMEN

Patients with chronic liver disease (CLD) experience health-related quality of life (HRQoL) and patient-reported outcomes (PROs) impairments. We assessed and identified predictors of HRQoL and PROs in CLD patients from Saudi Arabia (SA), Turkey and Egypt. Patients enrolled in Global Liver Registry™ with chronic hepatitis B (CHB), chronic hepatitis C (CHC) and non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH) were included. Clinical data and PRO questionnaires (FACIT-F, CLDQ and WPAI) were compared across countries. Linear regression identified PRO predictors. Of the 4014 included patients, 26.9% had CHB, 26.9% CHC and 46.1% NAFLD/NASH; 19.2% advanced fibrosis. Compared across countries, CHB patients were younger in Egypt (mean age [years] 41.2 ± 11.4 vs. 45.0 ± 10.3 SA, 46.1 ± 12.0 Turkey), most often employed in SA (64.8% vs. 53.2% Turkey) and had the lowest prevalence of obesity in Turkey (26.7% vs. 37.8% SA, 38.5% Egypt). In SA, CHB patients had lowest prevalence of fibrosis and comorbidities (all p < .01). There was a higher frequency of males with NAFLD/NASH in SA (70.0% vs. 49.6% Turkey, and 35.5% Egypt). Among NAFLD/NASH patients, CLDQ-NAFLD/NASH scores were highest in SA (mean total score: 5.3 ± 1.2 vs. 4.8 ± 1.2 Turkey, 4.1 ± 0.9 Egypt, p < .01). Independent predictors of worse PROs included younger age, female sex, advanced fibrosis, non-hepatic comorbidities and lack of regular exercise (all p < .05). Clinical presentation and PRO scores of CLD patients vary across SA, Turkey and Egypt. Impairment of HRQoL is associated with demographic factors, lack of regular exercise, advanced fibrosis and non-hepatic comorbidities.

RESUMEN

NAFLD has become a major public health problem for more than 2 decades with a growing prevalence in parallel with the epidemic of obesity and type 2 diabetes (T2D). The disease burden of NAFLD differs across geographical regions and ethnicities. Variations in prevalence of metabolic diseases, extent of urban-rural divide, dietary habits, lifestyles, and the prevalence of NAFLD risk and protective alleles can contribute to such differences. The rise in NAFLD has led to a remarkable increase in the number of cases of cirrhosis, hepatocellular carcinoma, hepatic decompensation, and liver-related mortality related to NAFLD. Moreover, NAFLD is associated with multiple extrahepatic manifestations. Most of them are risk factors for the progression of liver fibrosis and thus worsen the prognosis of NAFLD. All these comorbidities and complications affect the quality of life in subjects with NAFLD. Given the huge and growing size of the population with NAFLD, it is expected that patients, healthcare systems, and the economy will suffer from the ongoing burden related to NAFLD. In this review, we examine the disease burden of NAFLD across geographical areas and ethnicities, together with the distribution of some well-known genetic variants for NAFLD. We also describe some special populations including patients with T2D, lean patients, the pediatric population, and patients with concomitant liver diseases. We discuss extrahepatic outcomes, patient-reported outcomes, and economic burden related to NAFLD.

RESUMEN

BACKGROUND AND AIMS: With distinct mechanisms of action, the combination of tropifexor (TXR) and cenicriviroc (CVC) may provide an effective treatment for NASH. This randomized, multicenter, double-blind, phase 2b study assessed the safety and efficacy of TXR and CVC combination, compared with respective monotherapies. APPROACH AND RESULTS: Patients (N = 193) were randomized 1:1:1:1 to once-daily TXR 140 µg (TXR 140 ), CVC 150 mg (CVC), TXR 140 µg + CVC 150 mg (TXR 140 + CVC), or TXR 90 µg + CVC 150 mg (TXR 90 + CVC) for 48 weeks. The primary and secondary end points were safety and histological improvement, respectively. Rates of adverse events (AEs) were similar across treatment groups. Pruritus was the most frequently experienced AE, with highest incidence in the TXR 140 group (40.0%). In TXR and combination groups, alanine aminotransferase (ALT) decreased from baseline to 48 weeks (geometric mean change: -21%, TXR 140 ; -16%, TXR 140 + CVC; -13%, TXR 90 + CVC; and +17%, CVC). Reductions in body weight observed at week 24 (mean changes from baseline: TXR 140 , -2.5 kg; TXR 140 + CVC, -1.7 kg; TXR 90 + CVC, -1.0 kg; and CVC, -0.1 kg) were sustained to week 48. At least 1-point improvement in fibrosis stage/steatohepatitis resolution without worsening of fibrosis was observed in 32.3%/25.8%, 31.6%/15.8%, 29.7%/13.5%, and 32.5%/22.5% of patients in the TXR 140 , CVC, TXR 140 + CVC, and TXR 90 + CVC groups, respectively. CONCLUSIONS: The safety profile of TXR + CVC combination was similar to respective monotherapies, with no new signals. TXR monotherapy showed sustained ALT and body weight decreases. No substantial incremental efficacy was observed with TXR + CVC combination on ALT, body weight, or in histological end points compared with monotherapy.

RESUMEN

BACKGROUND AND AIMS: We evaluated the diagnostic accuracy of simple, noninvasive tests (NITs) in NAFLD patients with type 2 diabetes (T2D). METHODS AND RESULTS: This was an individual patient data meta-analysis of 1780 patients with biopsy-proven NAFLD and T2D. The index tests of interest were FIB-4, NAFLD Fibrosis Score (NFS), aspartate aminotransferase-to-platelet ratio index, liver stiffness measurement (LSM) by vibration-controlled transient elastography, and AGILE 3+. The target conditions were advanced fibrosis, NASH, and fibrotic NASH(NASH plus F2-F4 fibrosis). The diagnostic performance of noninvasive tests. individually or in sequential combination, was assessed by area under the receiver operating characteristic curve and by decision curve analysis. Comparison with 2278 NAFLD patients without T2D was also made. In NAFLD with T2D LSM and AGILE 3+ outperformed, both NFS and FIB-4 for advanced fibrosis (area under the receiver operating characteristic curve:LSM 0.82, AGILE 3+ 0.82, NFS 0.72, FIB-4 0.75, aspartate aminotransferase-to-platelet ratio index 0.68; p < 0.001 of LSM-based versus simple serum tests), with an uncertainty area of 12%-20%. The combination of serum-based with LSM-based tests for advanced fibrosis led to a reduction of 40%-60% in necessary LSM tests. Decision curve analysis showed that all scores had a modest net benefit for ruling out advanced fibrosis at the risk threshold of 5%-10% of missing advanced fibrosis. LSM and AGILE 3+ outperformed both NFS and FIB-4 for fibrotic NASH (area under the receiver operating characteristic curve:LSM 0.79, AGILE 3+ 0.77, NFS 0.71, FIB-4 0.71; p < 0.001 of LSM-based versus simple serum tests). All noninvasive scores were suboptimal for diagnosing NASH. CONCLUSIONS: LSM and AGILE 3+ individually or in low availability settings in sequential combination after FIB-4 or NFS have a similar good diagnostic accuracy for advanced fibrosis and an acceptable diagnostic accuracy for fibrotic NASH in NAFLD patients with T2D.

RESUMEN

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favor of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panelists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms "nonalcoholic" and "fatty" were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction-associated steatotic liver disease. There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction-associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction-associated steatotic liver disease, who consume greater amounts of alcohol per week (140-350 g/wk and 210-420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and nonstigmatising, and can improve awareness and patient identification.

RESUMEN

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), is common and closely associated with type 2 diabetes (T2D). We assessed the prevalence of NAFLD/MASLD in the general population and among patients with T2D in the Middle East and North Africa (MENA) region. METHODS: We searched PubMed and Embase for English-language articles published between 1990 and 2023 according to PRISMA. Each country's NAFLD/MASLD prevalence in the general population and in T2D patients was predicted by using a multivariable meta regression model. Input data were extracted from our systematic review, GBD and NCD Risk Factor Collaboration. Confidence intervals were constructed by using prediction intervals with the delta method. RESULTS: Meta-analytic pooling estimated the prevalence of NAFLD/MASLD as 39.43% in the general population and 68.71% among T2D patients. NAFLD/MASLD prevalence has increased from 35.42% (2008-2016) to 46.20% (2017-2020). Using GBD-2019 dataset, it was predicted that there are 141.51 million cases of NAFLD/MASLD in the MENA region. The highest number of NAFLD/MASLD cases were expected in Egypt (25.71 million), followed by Türkiye (23.33 million) and Iran (19.85 million). Estimated NAFLD prevalence exceeded 40% in 10 of 21 countries with the top countries being Kuwait (45.37%), Egypt (45.0%), Qatar (44.4%), and Jordan (43.3%). Furthermore, it was predicted that there are 24.96 million cases of NAFLD/MASLD with T2D in the MENA region. CONCLUSIONS: In the MENA region, prevalence of NAFLD/MASLD is very high and growing, necessitating an urgent need for regional public policy to deal with this growing burden.

RESUMEN

BACKGROUND & AIMS: There is a need to reduce the screen failure rate (SFR) in metabolic dysfunction-associated steatohepatitis (MASH) clinical trials (MASH+F2-3; MASH+F4) and identify people with high-risk MASH (MASH+F2-4) in clinical practice. We aimed to evaluate non-invasive tests (NITs) screening approaches for these target conditions. METHODS: This was an individual participant data meta-analysis for the performance of NITs against liver biopsy for MASH+F2-4, MASH+F2-3 and MASH+F4. Index tests were the FibroScan-AST (FAST) score, liver stiffness measured using vibration-controlled transient elastography (LSM-VCTE), the fibrosis-4 score (FIB-4) and the NAFLD fibrosis score (NFS). Area under the receiver operating characteristics curve (AUROC) and thresholds including those that achieved 34% SFR were reported. RESULTS: We included 2281 unique cases. The prevalence of MASH+F2-4, MASH+F2-3 and MASH+F4 was 31%, 24% and 7%, respectively. Area under the receiver operating characteristics curves for MASH+F2-4 were .78, .75, .68 and .57 for FAST, LSM-VCTE, FIB-4 and NFS. Area under the receiver operating characteristics curves for MASH+F2-3 were .73, .67, .60, .58 for FAST, LSM-VCTE, FIB-4 and NFS. Area under the receiver operating characteristics curves for MASH+F4 were .79, .84, .81, .76 for FAST, LSM-VCTE, FIB-4 and NFS. The sequential combination of FIB-4 and LSM-VCTE for the detection of MASH+F2-3 with threshold of .7 and 3.48, and 5.9 and 20 kPa achieved SFR of 67% and sensitivity of 60%, detecting 15 true positive cases from a theoretical group of 100 participants at the prevalence of 24%. CONCLUSIONS: Sequential combinations of NITs do not compromise diagnostic performance and may reduce resource utilisation through the need of fewer LSM-VCTE examinations.

RESUMEN

INTRODUCTION AND OBJECTIVES: Given the substantial burden of metabolic dysfunction-associated steatotic liver disease (MASLD), there is an urgent need to assess knowledge and awareness levels among physicians. We assessed MASLD knowledge among healthcare providers from Saudi Arabia, Egypt, and Türkiye. MATERIALS AND METHODS: Two global surveys containing 54-59 items assessed awareness and knowledge of MASLD/NAFLD- one was for hepatologists and gastroenterologists, and the second was for non-specialists (e.g. endocrinologists, primary care providers [PCPs], and other healthcare professionals). Data were collected using an electronic data collection form. Knowledge scores and variables associated with higher knowledge scores were compared across all specialties. RESULTS: A total of 584 physicians completed the survey (126 hepatologists, 178 gastroenterologists (GEs), 38 endocrinologists, 242 PCPs/others). Practice guidelines were the primary source for knowledge across all specialties (43-51%), then conferences (24-31%) except PCPs/others who selected the internet as the second common source (25%). Adherence to societal guidelines varied by specialty (81-84% of specialists vs 38-51% of non-specialists). Hepatologists and GEs showed similar mean knowledge scores (51-72% correct answers across three knowledge domains, p > 0.05); endocrinologists outperformed PCPs/others in knowledge scores in all knowledge domains, including Epidemiology/Pathogenesis (72% vs. 60%), Diagnostics (73% vs. 67%), and Treatment (78% vs. 67%) (all p < 0.01). Hospital-based practice and seeing a greater number of patients with MASLD/NAFLD were identified as independent predictors of higher knowledge scores among specialists (both p < 0.05). CONCLUSIONS: A knowledge gap in the identification, diagnosis, and management of MASLD/NAFLD was found despite the growing burden of MASLD/NAFLD in Saudi Arabia, Egypt, and Türkiye. Education to increase awareness is needed.

RESUMEN

PURPOSE: Planning intraoperative fluid therapy in patients undergoing major abdominal surgery is important. It was aimed to define the difference between fluid therapy protocols for renal function, bleeding and postoperative service follow-ups. MATERIALS AND METHODS: This is an observational case-controlled prospective study. Sixty patients aged 18-65 years who had undergone pancreatic surgery between December 2023- February 2023 were included in the study. Liberal (Group 1; n = 30) and targeted fluid therapies (Group 2; n = 30) were administered to the patients. Liberal fluid therapy was planned with 8-10 ml/kg/h crystalloid infusion. The targeted fluid therapy (TFT) group (Group 2; n = 30) began with a 2 ml/kg/h crystalloid infusion at the baseline. Additional fluid boluses were given in 250 ml of colloid infused over 10 min if PVI was > 13% for at least five minutes. The patients were staged using the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. The amount of bleeding during surgery was recorded for both groups. RESULTS: No significant difference was observed in postoperative renal function. A significant difference was observed in the amount of intraoperative bleeding. The amount of bleeding was greater in patients managed with liberal fluid therapy. No significant difference was observed between the groups in the oral intake (hour), drain withdrawal (hour) mobilization (hour) and discharge (day) times and there isn't any statistically significant differance between groups in cost effectivity (p>0.05). CONCLUSION: Kidney function was preserved during individualized targeted fluid therapy using non-invasive haemodynamic monitoring parameters.

RESUMEN

BACKGROUND: Premature ventricular contractions (PVCs) are common arrhythmias with diverse clinical implications. This retrospective study aimed to evaluate the efficacy of medical treatments using various clinical, imaging, and electrocardiographic parameters in patients with idiopathic PVCs. METHODS: A total of 1051 patients with idiopathic PVCs were retrospectively analyzed. Patients were categorized into three groups based on treatment response: beta-blocker (BB) responders (479 patients), calcium-channel blocker (CCB) responders (335 patients), and class 1c antiarrhythmic (AA) responders (237 patients). Clinical, imaging, and electrocardiographic data were collected and analyzed to assess the factors influencing treatment response. RESULTS: Age, left ventricular ejection fraction (LVEF), PVC QRS duration, CI variability, and multiple PVC morphologies were identified as significant factors affecting treatment response. Older age and lower LVEF were associated with better response to BB treatment, whereas CCB responders showed narrower QRS complexes. BB responders also exhibited higher CI variability, possibly linked to automaticity mechanisms. Moreover, the BB responder group had a higher frequency of multiple PVC morphologies. CONCLUSION: These findings emphasize the importance of tailored treatment approaches based on individual patient characteristics.

RESUMEN

PURPOSE: The aim of the study was to investigate the corneal and anterior segment characteristics in pseudoexfoliation syndrome (PXS), depending on the severity of the disease. MATERIALS AND METHODS: This cross-sectional study was conducted at a tertiary care hospital, in the ophthalmology department, in Turkey. Pseudoexfoliation syndrome group was classified into three groups. Pseudoexfoliative material on the part of the pupillary border was classified as group 1, on the entire pupillary border was classified as group 2, and pseudoexfoliative material on the entire pupillary border and iris surface was classified as group 3. The control group was composed of age and gender-matched individuals who had undergone a completely normal ophthalmologic examination. Scheimpflug tomography was performed to record tomographical data. RESULTS: The PXS groups 1, 2, and 3, along with the control group, consist of 29, 32, 33, and 42 participants, respectively. There was no significant difference in age-gender distribution between patients and the control group ( P >0.05). Group 3 showed significant differences in central corneal thickness compared with the control group ( P =0.001). In addition, anterior chamber angle was found to be significantly lower in group 3 than the control group ( P <0.001). In corneal densitometry (CD) values, significant increases compared with the control group were observed in groups 2 and 3 across all anterior annuli ( P <0.001). In group 1, significant increases observed in the anterior 6-10 mm and 10-12 mm annuli ( P <0.001). In the middle 6-10 mm annuluses, only group 3 showed a significant increase compared with the control group ( P <0.001). In the posterior 0-2, 2-6, and 6-10 mm annuli, significant increases compared with the control were observed only in groups 2 and 3 ( P =0.001, P =0.001, P <0.001, respectively). CONCLUSIONS: Corneal densitometry values, even without an increase in intraocular pressure, have a tendency to increase in PXS depending on the severity of the disease. While minimal changes were observed in the middle layer, it was particularly noted that the effects of the disease were more prominent in the peripheral cornea.

RESUMEN

BACKGROUND & AIMS: Currently available non-invasive tests, including fibrosis-4 index (FIB-4) and liver stiffness measurement (LSM by VCTE), are highly effective at excluding advanced fibrosis (AF) (F ≥3) or cirrhosis in people with non-alcoholic fatty liver disease (NAFLD), but only have moderate ability to rule-in these conditions. Our objective was to develop and validate two new scores (Agile 4 and Agile 3+) to identify cirrhosis or AF, respectively, with optimized positive predictive value and fewer indeterminate results, in individuals with NAFLD attending liver clinics. METHODS: This international study included seven adult cohorts with suspected NAFLD who underwent liver biopsy, LSM and blood sampling during routine clinical practice or screening for trials. The population was randomly divided into a training set and an internal validation set, on which the best-fitting logistic regression model was built, and performance and goodness of fit were assessed, respectively. Furthermore, both scores were externally validated on two large cohorts. Cut-offs for high sensitivity and specificity were derived in the training set to rule-out and rule-in cirrhosis or AF and then tested in the validation set and compared to FIB-4 and LSM. RESULTS: Each score combined LSM, AST/ALT ratio, platelets, sex and diabetes status, as well as age for Agile 3+. Calibration plots for Agile 4 and Agile 3+ indicated satisfactory to excellent goodness of fit. Agile 4 and Agile 3+ outperformed FIB-4 and LSM in terms of AUROC, percentage of patients with indeterminate results and positive predictive value to rule-in cirrhosis or AF. CONCLUSIONS: The two novel non-invasive scores improve identification of cirrhosis or AF among individuals with NAFLD attending liver clinics and reduce the need for liver biopsy in this population. IMPACT AND IMPLICATIONS: Non-invasive tests currently used to identify patients with advanced fibrosis or cirrhosis, such as fibrosis-4 index and liver stiffness measurement by vibration-controlled transient elastography, have high negative predictive values but high false positive rates, while results are indeterminate for a large number of cases. This study provides scores that will help the clinician diagnose advanced fibrosis or cirrhosis. These new easy-to-implement scores will help liver specialists to better identify (1) patients who need more intensive follow-up, (2) patients who should be referred for inclusion in therapeutic trials, and (3) which patients should be treated with pharmacological agents when effective therapies are approved.

RESUMEN

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favour of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panellists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms "nonalcoholic" and "fatty" were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction-associated steatotic liver disease (MASLD). There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction-associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction-associated steatotic liver disease, who consume greater amounts of alcohol per week (140-350 g/wk and 210-420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and non-stigmatising, and can improve awareness and patient identification.

RESUMEN

Chronic hepatitis B (CHB) infection is one of the most common causes of cirrhosis and liver cancer worldwide. Our aim was to assess clinical and patient-reported outcome (PRO) profile of CHB patients from different regions of the world using the Global Liver Registry. The CHB patients seen in real-world practices are being enrolled in the Global Liver Registry. Clinical and PRO (FACIT-F, CLDQ, WPAI) data were collected and compared to baseline data from CHB controls from clinical trials. The study included 1818 HBV subjects (48 ± 13 years, 58% male, 14% advanced fibrosis, 7% cirrhosis) from 15 countries in 6/7 Global Burden of Disease super-regions. The rates of advanced fibrosis varied (3-24%). The lowest PRO scores across multiple domains were in HBV subjects from the Middle East/North Africa (MENA), the highest - Southeast/East and South Asia. Subjects with advanced fibrosis had PRO impairment in 3 CLDQ domains, Activity of WPAI (p < 0.05). HBV subjects with superimposed fatty liver had more PRO impairments. In multivariate analysis adjusted for location, predictors of PRO impairment in CHB included female sex, advanced fibrosis, and non-hepatic comorbidities (p < 0.05). In comparison to Global Liver Registry patients, 242 controls from clinical trials had better PRO scores (Abdominal, Emotional, and Systemic scores of CLDQ, all domains of WPAI) (p < 0.05). In multivariate analysis with adjustment for location and clinicodemographic parameters, the associations of PROs with the enrollment setting (real-life Global Liver Registry vs. clinical trials) were no longer significant (all p > 0.10). The clinico-demographic portrait of CHB patients varies across regions of the world and enrollment settings. Advanced fibrosis and non-hepatic comorbidities are independently associated with PRO impairment in CHB patients.

RESUMEN

BACKGROUND: Inflammatory bowel disease (IBD), which is an umbrella term used for ulcerative colitis (UC) and Crohn's disease (CD), is associated with an increased risk for atherosclerotic cardiovascular disease (CVD). We aimed to investigate the association of local and systemic biomarkers of inflammation and gut microbiota-derived metabolite trimethylamine N-oxide (TMAO) with endothelial and coronary microvascular dysfunction in IBD. METHODS: A total of 56 patients with IBD (20 with UC and 36 with CD) and 34 age and gender matched controls were included. For all participants, samples were collected to analyze faecal calprotectin, and TMAO concentrations. Ultrasound-based examinations were done to measure flow-mediated vasodilatation (FMD) and coronary flow velocity reserve (CFVR). RESULTS: Patients with IBD had lower CFVR (2.07 (1.82-2.40)) and FMD (8.7 ± 3.7) as compared to controls (2.30 (2.07-2.74), p = 0.005 and 11.9 ± 6.8, p = 0.03). In patients with IBD, TMAO concentration (r = -0.30, p = 0.03), C-reactive protein (r = -0.29, p = 0.03) and WBC count (r = -0.37, p = 0.006) had a significant negative correlation with CFVR, and TMAO (ß = -0.27, 95 % CI: -0.23 to -0.02) and WBC count (ß = -0.31, 95 % CI: -0.56 to -0.06) were significant predictors of CFVR after multivariate adjustment. None of the biomarkers of inflammation or TMAO showed significant correlations with FMD. In patients with UC, TMAO showed a significant correlation with both CFVR (r = -0.55, p = 0.01) and FMD (r = -0.60, p = 0.005) while only WBC count had a statistically significant correlation with CFVR (r = -0.49, p = 0.004) in patients with CD. CONCLUSIONS: Gut microbiota-derived metabolite TMAO and biomarkers of systemic inflammation are associated with measures of endothelial/coronary microvascular dysfunction in patients with IBD.

RESUMEN

INTRODUCTION: While poor oral hygiene has been previously associated with an increased risk of nonalcoholic fatty liver disease (NAFLD), its association with hepatic fibrosis remains unclear. Here, we sought to analyze if toothbrushing frequency, an easy-to-assess indicator of oral health habits, would be associated with liver stiffness measurement (LSM) by transient elastography (TE) in patients with an established diagnosis of NAFLD. METHODS: In this registry-based study, LSM was measured in 1,156 patients with NAFLD and analyzed in relation to the self-reported daily frequency of toothbrushing. LSM values ≥12 kPa were considered indicative of cirrhosis. RESULTS: A trend toward a stepwise decrease (cross-sectional p = 0.13) in LSM was found in patients who reported having their teeth brushed more frequently: less than once a day (10.6 ± 8.6 kPa; 13% of the study sample), once a day (9.95 ± 8.40 kPa; 40%), twice a day (9.21 ± 7.63 kPa; 43%), and after every meal (8.91 ± 5.30 kPa; 4%). Patients who brushed their teeth less than once a day had a significantly higher prevalence of LSM values ≥12 kPa (p < 0.05). In multivariable logistic regression analysis, the association of LSM values ≥12 kPa with toothbrushing habits remained statistically significant for less than once a day (odds ratio = 1.69, 95% confidence interval = 1.07-2.66, p = 0.02) with reference to twice a day or after every meal. CONCLUSION: Among patients with NAFLD, there is an independent association between brushing teeth less than once a day and TE-established cirrhosis.
