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

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

Metabolic (dysfunction)-associated fatty liver disease has taken importance during the last two years, given the new criteria for diagnosis compared to the previous criteria used to define non-alcoholic fatty liver disease. Multiple studies have also shown that this definition better adjusts to the pathogenesis and patient characteristics with fatty liver.

RESUMEN

BACKGROUND AND AIM: DNA methylation plays a critical role in the control of important cellular processes. The present study assessed the impact of promoter methylation (PM) of some genes on the antiviral response to antiviral therapy and it's relation to the presence of fibrosis in HCV-4 infected patients from Egypt. MATERIAL AND METHODS: Clinical, laboratory and histopathological data of 53 HCV-4 infected patients who were subjected to combined antiviral therapy were collected; patients were classified according to their response to treatment and the fibrosis status. The methylation profiles of the studied groups were determined using the following genes: APC, P14ARF, P73, DAPK, RASSF1A, and O6MGMT in patients' plasma. RESULTS: O6MGMT and P73 showed the highest methylation frequencies (64.2 and 50.9%) while P14 showed the lowest frequency (34%). Sustained virological response (SVR) was 54.7%with no significant difference in clinico-pathological or laboratory features between the studied groups. PM of O6MGM was significantly higher in non-responders (p value 0.045) while DAPK showed high methylation levels in responders with no significance (p value: 0.09) andPM of RASSF1A was significantly related to mild fibrosis (p value: 0.019). No significant relations were reported between PM of any of the studied genes and patients' features. CONCLUSION: PM of some Tumor Suppressor genes increases in chronic active HCV-4. However, only 06MGMT can be used as a predictor of antiviral response and RASSF1A as a marker of marked fibrosis in this small set of patients. An extended study, including more patients is required to validate the results of this preliminary study.

RESUMEN

UNLABELLED: BACKGROUND AND RATIONALE FOR THE STUDY: Chronic HCV is a major cause of HCC development. Caspase Recruitment Domains (CARD) is protein modules that regulate apoptosis and play an important role in various carcinogenesis processes, our aim is to assess the possible role of CARD9, CARD10 and Caspase only protein (COP) in progression of liver fibrosis and pathogenesis of HCC in Egyptian chronic HCV patients. MATERIAL AND METHODS: 130 patients were recruited and classified into 4 groups; I: chronic HCV, II: chronic active hepatitis, III: liver cirrhosis, IV: HCV related HCC. Biochemical, virological studies, abdominal ultrasonography and liver biopsy were performed. Quantitative estimation of mRNA of CARD9, CARD10 and COP gene expression was performed by RT- PCR in liver biopsy from all patients. RESULTS: In HCC patients; age, AFP and liver profile were significantly higher, HB and platelets were significantly lower (p value <0.01). The expression levels of mRNA of CARD9, CARD10 and COP in liver biopsies of HCC were significantly higher than other groups with direct correlation with age and no correlation with AFP, viral load, liver fibrosis or necroinflammatory activity. On differentiation between HCC and non HCC patients each CARD was assessed separately and combined, on combing the 3 CARDs, the sensitivity was 100%, specificity was 48%, positive predictive value 47% and negative predictive value 100%. CONCLUSIONS: CARD9, CARD10 and COP had no role in liver fibrosis but may be involved in hepatic carcinogenesis and they could be used as markers for HCC diagnosis and candid genes for molecular target therapy.
