Background: Recently, a panel of multi-society experts proposed steatotic liver disease (SLD) as an alternative terminology for metabolic dysfunction-associated fatty liver disease (MAFLD) or nonalcoholic fatty liver disease (NAFLD)., Aims: We compared the impact of SLD, subtype of SLD, MAFLD and NAFLD on all-cause and cause-specific mortality., Methods: A total of 7811 individuals in the third National Health and Nutrition Examination Survey and linked mortality through 2019 were analysed. SLD was defined based on ultrasonographic hepatic steatosis. SLD, subtype of SLD and MAFLD were defined using the proposed definitions. The Cox proportional hazard model assessed all-cause/cause-specific mortality., Results: During a median follow-up of 27.1 years, individuals with SLD and MAFLD experienced approximately 13%-23% higher risk of all-cause mortality (hazard ratio [HR]: 1.15, 95% confidence interval [CI]: 1.02-1.29 for SLD; HR: 1.23, 95% CI: 1.09-1.38 for MAFLD; HR: 1.13, 95% CI: 1.01-1.27 for metabolic dysfunction-associated steatotic liver disease [MASLD]). Individuals with MetALD demonstrated a higher risk of all-cause (HR: 1.68, 95% CI: 1.10-2.57) and cancer-related mortality (HR: 2.40, 95% CI: 1.23-4.66). MASLD with advanced fibrosis had an increased risk of all-cause mortality compared to MASLD without advanced fibrosis., Conclusions: SLD, especially MASLD and MetALD, is associated with increased all-cause mortality among adults in the US. Given this significant association between SLD or subtype of SLD (MASLD and MetALD) and all-cause mortality, adopting the proposed SLD criteria may help identify a sub-group of individuals with SLD who are at an increased risk for all-cause mortality., (© 2024 John Wiley & Sons Ltd.)

Background & Aims: The cost‐effectiveness to screen hepatic fibrosis in at‐risk population as recommended by several professional societies has been limited. This study aimed to investigate the cost‐effectiveness of this screening strategy in the expanded at‐risk population recently proposed by several societies. Methods: A combined model of the decision tree and Markov models was developed to compare expected costs, quality‐adjusted life‐years (QALYs) and incremental cost‐effectiveness ratio (ICER) between screening and no screening groups. The model included liver disease‐related health states and cardiovascular disease (CVD) states as a base‐case analysis. Screening strategy consisted of fibrosis‐4 index (FIB‐4) followed by vibration‐controlled transient elastography (VCTE) and intensive lifestyle intervention (ILI) as a treatment for diagnosed patients. Results: Cost‐effectiveness analysis showed that screening the at‐risk population entailed $298 incremental costs and an additional 0.0199 QALY per patient compared to no screening (ICER $14 949/QALY). Screening was cost‐effective based on the implicit ICER threshold of $25 000/QALY in Korea. When the effects of ILI on CVD and extrahepatic malignancy were incorporated into the cost‐effectiveness model, the ICER decreased by 0.85 times from the base‐case analysis (ICER $12 749/QALY). In contrast, when only the effects of liver disease were considered in the model, excluding cardiovascular disease effects, ICER increased from the baseline case analysis to $16 305. Even when replacing with medical costs in Japan and U.S., it remained cost‐effective with the estimate below the countries' ICER threshold. Conclusions: Our study provides compelling evidence supporting the cost‐effectiveness of FIB‐4‐based screening the at‐risk population for advanced hepatic fibrosis. [ABSTRACT FROM AUTHOR]

Background and Aims: Sex steroid hormones and sex hormone-binding globulin (SHBG) have a role in predisposing individuals to nonalcoholic fatty liver disease (NAFLD), but their effects are known to differ between men and women. The testosterone- to-estradiol ratio (T/E2 ratio) and free androgen index (FAI) were known biomarkers for the hormonal milieu. We investigated whether sex steroid hormones, T/E2 ratio, FAI, and SHBG were associated with NAFLD in US adults. Methods: A cross-sectional analysis using the 2013--2016 National Health and Nutrition Examination Survey (NHANES) was performed. NAFLD was defined by utilizing the Hepatic Steatosis Index (HSI) and the US fatty liver index (USFLI) without other causes of chronic liver disease. Results: Out of 8687 subjects (49.5% male), low total testosterone levels were associated with progressively higher odds of NAFLD in men. Increasing T/E2 ratio was inversely associated with higher odds of NAFLD in men. Low serum SHBG levels were independently associated with an increased risk of NAFLD regardless of sex and menopausal status. Increasing FAI was independently associated with NAFLD. When we additionally adjusted for SHBG, T/E2 ratio, not total testosterone, was inversely associated with NAFLD in a dose-dependent manner. Increasing FAI was associated with higher odds of NAFLD in premenopausal women and marginally associated with NAFLD in postmenopausal women. Conclusion: The T/E2 ratio and SHBG were inversely associated with an increased risk of NAFLD in men. In women, increasing FAI was associated with NAFLD, whereas SHBG was inversely associated with NAFLD. [ABSTRACT FROM AUTHOR]

Background: Depression has been associated with nonalcoholic fatty liver disease (NAFLD). Data addressing the impact of depression on NAFLD‐related mortality are evolving. We aim to study the association of depression in NAFLD and all‐cause/cause‐specific mortality in the United States. Methods: A total of 11,877 individuals with NAFLD in the 2007–2016 National Health and Nutrition Examination Survey with the availability of linked mortality through 2019 were analysed. NAFLD was defined by utilizing the hepatic steatosis index in the absence of known causes of chronic liver disease. Depression and functional impairment due to depression were assessed using the Patient Health Questionnaire. Results: During the median follow‐up of 7.6 years, individuals with depression among individuals with NAFLD had a 35% higher all‐cause mortality than those without depression (hazard ratio [HR]: 1.35, 95% confidence interval [CI]: 1.03–1.75) after adjusting for demographic, lifestyle and clinical risk factors. NAFLD with functional impairment due to depression had a 62% higher all‐cause mortality than NAFLD without functional impairment (HR: 1.62, 95% CI: 1.10–2.39). Depression in NAFLD was associated with an approximately 50% increase in the risk for cardiovascular mortality, with a 2‐fold higher cardiovascular mortality in those with functional impairment compared to those without (HR: 2.07, 95% CI: 1.30–3.30). However, there was no significant difference in cancer‐ and accident‐related mortalities in NAFLD with or without depression. Conclusions: Depression among individuals with NAFLD was associated with a higher risk for all‐cause and cardiovascular mortality in the United States. [ABSTRACT FROM AUTHOR]
