RESUMEN

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD) recurrence after liver transplantation (LT) seems unavoidable and gradual. We aimed to evaluate the diagnostic accuracy in the post-LT setting of patients transplanted for metabolic dysfunction-associated steatohepatitis (MASH) of recurrent hepatic steatosis and fibrosis identified with FibroScan, compared to biopsy findings. METHODS: This prospective cohort study included adults transplanted for MASH between 2010 and 2022 in three LT centres in Spain who underwent FibroScan and biopsy at least 1-year after LT. RESULTS: In total, 44 patients transplanted for MASH after LT were included. The median time from LT to biopsy and FibroScan was 24.5 (interquartile range [IQR]:16-46) and 26.0 (IQR: 16.8-41.5) months, respectively. The median time between biopsy and FibroScan was 2.0 (IQR: 0-5) months. On FibroScan, significant steatosis was diagnosed in about half of the patients (n = 21, 47.7%), yet advanced fibrosis in only two cases (4.6%). On biopsy, a quarter of biopsied patients (n = 11, 25%) had a MASH diagnosis, two (4.6%) with significant fibrosis and one (2.3%) with cirrhosis. All patients with liver stiffness measurement (LSM) values <8 kPa (n = 35, 79.5%) had a fibrosis stage ≤F1 (negative predictive value = 100%). The combination of post-LT hypertension (odds ratio [OR]: 12.0, 95% confidence interval [CI]: 1.8-80.4, p = .010) and post-LT dyslipidaemia (OR: 7.9, 95% CI: 1.3-47.1, p = .024) with LSM (OR: 1.7, 95% CI: 1.1-2.8, p = .030) was independently associated with MASLD. CONCLUSIONS: Although biopsy remains the gold standard for detecting fibrosis, our results suggest that LSM values <8 kPa after LT for MASH are strongly correlated with absence of significant/advanced fibrosis.

RESUMEN

PURPOSE OF REVIEW: To critically summarize evidence on the potential role of osteokines in the pathogenesis and progression of nonalcoholic fatty liver disease (NAFLD). RECENT FINDINGS: There are emerging data supporting that certain osteokines, which are specific bone-derived proteins, may beneficially or adversely affect hepatic metabolism, and their alterations in the setting of osteoporosis or other bone metabolic diseases may possibly contribute to the development and progression of NAFLD. There is evidence showing a potential bidirectional association between NAFLD and bone metabolism, which may imply the existence of a liver-bone axis. In this regard, osteocalcin, osteoprotegerin, bone morphogenic protein 4 (BMP4) and BMP6 appear to have a positive impact on the liver, thus possibly alleviating NAFLD, whereas osteopontin, receptor activator of nuclear factor kappa Β ligand (RANKL), sclerostin, periostin, BMP8B, and fibroblast growth factor 23 (FGF23) appear to have a negative impact on the liver, thus possibly exacerbating NAFLD. The potential implication of osteokines in NAFLD warrants further animal and clinical research in the field that may possibly result in novel therapeutic targets for NAFLD in the future.

RESUMEN

BACKGROUND: Previous studies have reported an association between metabolic dysfunction-associated steatotic liver disease (MASLD) and the risk of serious bacterial infections. However, the magnitude of the risk and whether this risk varies with the severity of MASLD remains uncertain. We performed a meta-analysis of observational studies to quantify the association between MASLD and serious bacterial infections requiring hospital admission. METHODS: We systematically searched PubMed, Scopus, Web of Science and Embase from database inception to 1 April 2024, using predefined keywords to identify studies examining the risk of serious bacterial infections among individuals with and without MASLD. MASLD was diagnosed using liver biopsy, imaging or International Classification of Diseases codes. Meta-analysis was performed using random-effects modelling. RESULTS: We identified six cross-sectional and two prospective cohort studies with aggregate data on ~26.6 million individuals. MASLD was significantly associated with higher odds of serious bacterial infections (pooled random-effects odds ratio 1.93, 95% confidence interval [CI] 1.44-2.58; I2 = 93%). Meta-analysis of prospective cohort studies showed that MAFLD was associated with an increased risk of developing serious bacterial infections (pooled random-effects hazard ratio 1.80, 95% CI 1.62-2.0; I2 = 89%). This risk further increased across the severity of MASLD, especially the severity of fibrosis (pooled random-effects hazard ratio 2.42, 95% CI 1.89-2.29; I2 = 92%). These results remained significant after adjusting for age, sex, obesity, diabetes and other potential confounders. Sensitivity analyses did not modify these findings. The funnel plot did not reveal any significant publication bias. CONCLUSIONS: This meta-analysis shows a significant association between MASLD and an increased risk of serious bacterial infections requiring hospital admission.

RESUMEN

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD), in the context of autoimmune hepatitis (AIH) among liver transplantation (LT) candidates or recipients remains poorly understood. This study compares waitlist and post-LT outcomes in patients with MASLD/AIH to MASLD and AIH alone. METHODS: Using the united network organ sharing database (2002-2022), we compared waitlist outcomes and post-LT survival among patients with MASLD/AIH (n = 282), AIH (n = 5812), and MASLD (n = 33 331). Competing risk, Kaplan Meier estimates and Cox proportional hazard analyses were performed. RESULTS: MASLD/AIH group had the highest rates of encephalopathy and ascites, and highest MELD scores. MASLD/AIH patients had higher transplantation incidence (adjusted subdistribution hazard ratio [aSHR] 1.64, 95% CI 1.44-1.85; p < .001) and lower waitlist removal risk (aSHR .30, 95% CI .20-.44; p < .001) compared to MASLD alone. One-year post-LT survival favoured MASLD compared to AIH (patient: 92% vs. 91%, p < .001; graft: 89% vs. 88%, p < .001) and MASLD/AIH (patient: 92% vs. 90%, p = .008; graft: 89% vs. 88%, p = .023). Recipients with MASLD/AIH showed no significant difference in survival at 10-year post-LT compared to MASLD (patient: 63% vs. 61%, p = .68; graft 60% vs. 59%, p = .83) and AIH (patient: 63% vs. 70%, p = .07; graft: 60% vs. 64%, p = .42). CONCLUSIONS: Our study showed that MASLD/AIH patients demonstrate higher LT incidence and lower dropout rates. Long-term post-LT outcomes did not significantly differ between groups. Further prospective multicenter studies are needed to validate these findings.

RESUMEN

Background: The controlled attenuation parameter (CAP) enables the noninvasive assessment of liver steatosis. We performed a systematic review and meta-analysis to evaluate the diagnostic accuracy of CAP for identifying liver steatosis in patients at risk for metabolic dysfunction-associated steatotic liver disease (MASLD), using magnetic resonance imaging proton density fat fraction (MRI-PDFF) as the reference standard. Methods: We searched Medline, Embase, Cochrane Library and gray literature sources up to March 2024. We defined MASLD as MRI-PDFF ≥5%. We also assessed the accuracy of CAP for identifying patients with MRI-PDFF ≥10%. We calculated pooled sensitivity and specificity estimates using hierarchical random-effects models. We assessed the risk of bias using the Quality Assessment of Diagnostic Accuracy Studies 2 tool, and the certainty in meta-analysis estimates using the Grading of Recommendations Assessment, Development and Evaluation framework. Results: We included 8 studies with 1116 participants. The prevalence of MASLD ranged from 65.2-93.9%. Pooled sensitivity and specificity of CAP for MRI-PDFF ≥5% were 0.84 (95% confidence interval [CI] 0.79-0.88) and 0.77 (95%CI 0.68-0.84), respectively, with an area under the receiver operating characteristic curve (AUROC) of 0.88. The pooled sensitivity and specificity for MRI-PDFF ≥10% were 0.83 (95%CI 0.80-0.87) and 0.72 (95%CI 0.59-0.82), with an AUROC of 0.85. The certainty in our estimates was low to very low because of the high risk of bias, inconsistency and imprecision. Conclusions: CAP has acceptable diagnostic accuracy for both MRI-PDFF ≥5% and MRI-PDFF ≥10%. Adequately powered and rigorously conducted diagnostic accuracy studies are warranted to establish the optimal CAP thresholds.

RESUMEN

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease associated with metabolic dysfunction, ranging from hepatic steatosis with or without mild inflammation to nonalcoholic steatohepatitis, which can rapidly progress to liver fibrosis and even liver cancer. In 2023, after several rounds of Delphi surveys, a new consensus recommended renaming NAFLD as metabolic dysfunction-associated steatotic liver disease (MASLD). Ninety-nine percent of NAFLD patients meet the new MASLD criteria related to metabolic cardiovascular risk factors under the "multiple parallel hits" of lipotoxicity, insulin resistance (IR), a proinflammatory diet, and an intestinal microbiota disorder, and previous research on NAFLD remains valid. The NLRP3 inflammasome, a well-known member of the pattern recognition receptor (PRR) family, can be activated by danger signals transmitted by pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), as well as cytokines involved in immune and inflammatory responses. The activation of the NLRP3 inflammasome pathway by MASLD triggers the production of the inflammatory cytokines IL-1ß and IL-18. In MASLD, while changes in the composition and metabolites of the intestinal microbiota occur, the disrupted intestinal microbiota can also generate the inflammatory cytokines IL-1ß and IL-18 by damaging the intestinal barrier, negatively regulating the liver on the gut-liver axis, and further aggravating MASLD. Therefore, modulating the gut-microbiota-liver axis through the NLRP3 inflammasome may emerge as a novel therapeutic approach for MASLD patients. In this article, we review the evidence regarding the functions of the NLRP3 inflammasome and the intestinal microbiota in MASLD, as well as their interactions in this disease.

RESUMEN

Optimal non-invasive biomarkers for metabolic dysfunction-associated steatotic liver disease (MASLD) remain elusive, especially in the detection of early stages. This study tested in an asymptomatic cohort of 171 men (49.2 ± 8.6 years) and 131 women (51.8 ± 8.5 years) whether waist circumference (WC) and circulating levels of insulin-like growth factor-binding protein 2 (IGFBP-2) could identify individuals with liver fat >5% as assessed by magnetic resonance spectroscopy. Participants with high WC (> 85 or 90 cm for women and men, respectively) and low IGFBP-2 (< 260 or 230 ng/mL for women and men, respectively) were characterized by a higher risk of having MASLD (46.3%, p < 0.0001). Among the 68 individuals with MASLD, 73.5% fell into the subgroup with high WC and low IGFBP-2 concentrations (p < 0.0001). When combined, these markers reached a sensitivity of 73.5% and specificity of 75.2% for MASLD. Thus, WC and plasma IGFBP-2 levels might be useful as a novel, simple, and non-invasive index to support existing tools in the identification of individuals at risk of early-stage MASLD.

RESUMEN

BACKGROUND & AIMS: The mechanisms underlying the regulation of hepatocyte non-receptor tyrosine kinases in metabolic dysfunction-associated steatohepatitis (MASH) remain largely unclear. METHODS: Hepatocyte-specific overexpression or deletion and anti-protein tyrosine kinase 2 beta (PYK2) or anti-TRAF6-binding protein (T6BP) crosslinking were utilised to study fatty liver protection by T6BP. P-PTC, a peptide-proteolysis targeting chimaera, degrades PYK2 to block MASH progression. RESULTS: Since PYK2 activation is promoter signalling in steatohepatitis development, we find that T6BP is a novel and critical suppressor of PYK2 that reduces hepatic lipid accumulation, pro-inflammatory factor release, and pro-fibrosis production by ubiquitin ligase CBL to degrade PYK2. Mechanistic evidence suggests that T6BP directly targets PYK2 and prevents its N-terminal FERM domain-triggered dimerization, disrupting downstream PYK2-JNK signalling hyperactivation. Additionally, T6BP favourably recruits CBL, a particular E3 ubiquitin ligase targeting PYK2, to form a complex and degrade PYK2. T6BP (F1), a core fragment of T6BP, directly blocks N-terminal FERM domain-associated dimerization of PYK2, followed by T6BP-recruiting CBL-mediated PYK2 degradation in a typical T6BP-dependent manner when the tiny fragment is specifically expressed using thyroxine binding globulin (TBG)-ground vectors. This inhibits the progression of MASH, metabolic dysfunction-associated steatotic liver disease (MASLD)-related HCC (MASH-HCC), and metabolic syndrome in dietary rodent models. First-ever peptide-proteolysis targeting chimaera (P-PTC) based on the core segment of T6BP as a ligand for targeted recruitment of CBL targeting metabolic disorders like MASH has been devised and validated in animal models. CONCLUSIONS: Our study revealed a previously unknown mechanism: identification of T6BP as a key eliminator of fatty liver strongly contributes to the development of promising therapeutic targets, and the discovery of crucial fragments of T6BP-based pharmacon that interrupt PYK2 dimerization are novel and viable treatments for fatty liver and its advanced symptoms and complications. IMPACT AND IMPLICATIONS: Excessive high-energy diet ingestion is critical in driving steatohepatitis via regulation of hepatocyte non-receptor tyrosine kinases. The mechanisms under lying the regulation of hepatocyte PYK2 in metabolic dysfunction-associated steatohepatitis (MASH) remain largely unclear. Here, we found that T6BP as a critical fatty liver eliminator has a significant impact on the development of promising therapeutic targets. Additionally, vital T6BP-based pharmacon fragments that impede PYK2 dimerization have been found, offering new and effective treatments for advanced fatty liver symptoms and complications.

RESUMEN

AIM: To examine the associations of healthy lifestyles with risk of all-cause and cause-specific mortality among adults with metabolic dysfunction-associated steatotic liver disease (MASLD), and whether the association was mediated by systemic immune-inflammatory biomarkers (SIIBs). METHODS: The study included 10,347 subjects with MASLD, who were enrolled in the Dongfeng-Tongji cohort study. The healthy lifestyles referred to non-smoking, being physically active (≥7.5 metabolic equivalents-hours/week), low-risk alcohol consumption (1-14 g/day for women and 1-28 g/day for men), and optimal sleep duration (≥6 to ≤8 h/day). Cox proportional hazard models were used to examine the relationship between each lifestyle and SIIBs with the risk of all-cause and cause-specific mortality. A mediation analysis was conducted to investigate the role of SIIBs on the association between healthy lifestyles and mortality. RESULTS: There were 418 MASLD subjects dead till the follow-up of 2018, including 259 deaths from cardiovascular disease (CVD). Compared to MASLD participants with 0-1 healthy lifestyle score (HLS), those with 3-4 HLS had the lowest risk of all-cause mortality [hazard ratio (HR), 0.46; 95% CI, (0.36-0.60)], and CVD mortality [HR (95%CI), 0.41 (0.29-0.58)]. Mediation analyses indicated that SIIBs mediated the association between healthy lifestyles and mortality, with proportions ranging from 2.5% to 6.1%. CONCLUSIONS: These findings suggest that adherence to healthy lifestyles can significantly reduce mortality for MASLD patients, and the decreased SIIBs may partially explain the protection mechanism of healthy lifestyles.

RESUMEN

Metabolic dysfunction-associated steatotic liver disease (MASLD)-and its worse form, metabolic-associated steatohepatitis (MASH), characterised by inflammation and liver damage-corresponds to the liver's involvement in metabolic syndrome, which constitutes an economic burden for healthcare systems. However, the biomolecular pathways that contribute to steatotic liver disease are not completely clear. Abnormalities of bone metabolism are frequent in people affected by metabolic liver disease, with reduced bone density and an increased risk of fracture. Receptor activator of NF-κB (RANK), receptor activator of NF-κB ligand (RANKL), and osteoprotegerin(OPG) are critical regulators of bone metabolism, performing pleiotropic effects, and may have potential involvement in metabolic disorders like MASLD, resulting in a topic of great interest and intrigue. This narrative review aims to investigate this potential role and its implications in MASLD development and progression and in hepatocellular carcinoma, which represents its worst complication.

RESUMEN

INTRODUCTION: Patients with type 2 diabetes (T2D), particularly those from historically marginalized racial and ethnic groups, are at high risk of poor outcomes from metabolic dysfunction-associated steatotic liver disease (MASLD). Evidence-based management (EBM) of MASLD can prevent its progression to cirrhosis and poor outcomes, yet rates of EBM of MASLD are low in T2D. METHODS: In this pilot study of ten participants, we examined the feasibility and acceptability of a telehealth intervention that delivered EBM of MASLD in Latino/a and Black patients with T2D in the Duke Healthcare System. The intervention included: (a) MASLD education; (b) diet/lifestyle counseling; (c) T2D medication adjustment (i.e., to promote liver health) and (d) ordering of clinically indicated tests and referrals. This 3-month intervention was delivered by an endocrinologist over three virtual study visits. Phone interviews were conducted at study conclusion. We examined rates of recruitment, retention, T2D medication adjustment, and ordering of clinically indicated tests/referrals. RESULTS: The median age of our cohort was 54.0 (44.0, 59.0); six and four participants self-identified as Latino/a ethnicity and Black race, respectively. Retention rate in this study was 100% (n = 10/10), and all scheduled visits were completed (n = 30/30). Recruitment occurred over one month, and the rate was 25.8% (n = 8/31) by telephone call and 10% (n = 2/20) by electronic health record message. The intervention was highly acceptable based on a median Treatment Acceptability and Preferences score of 4.0 (4.0, 4.0). In exit interviews, all participants reported improved understanding of MASLD and its link to diabetes. All participants received T2D medication adjustment (n = 5/10) and/or clinically indicated testing/referral (n = 10/10) for the purpose of improving MASLD. CONCLUSIONS: We demonstrated that a telehealth intervention designed to proactively deliver EBM of MASLD was feasible and acceptable in a cohort of Latino/a and Black patients with T2D. Opportunities existed to better align each participants' care with guideline-based care of MASLD.

RESUMEN

Metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed as a new name for the previous non-alcoholic fatty liver disease (NAFLD). There are some differences between MASLD and NAFLD, e.g., diagnostic criteria. MASLD is a hepatic steatosis without harmful alcohol consumption and is caused by metabolic factors. The prevalence of MASLD varies amongst different populations. The change in lifestyle plays a fundamental role in MASLD management, while there is no registered pharmacotherapy in this indication. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have been suggested to have a beneficial effect on hepatic steatosis, hence, they have been widely investigated as potential therapeutics in MASLD. In this review, we aimed to thoroughly summarize current evidence from original research about the effects of SGLT2i use on MASLD. Almost all discussed studies advocate using SGLT2i in MASLD because of their beneficial effects. It includes the loss of body weight, which is beneficial per se, and the improvement in hepatic parameters. Most importantly, steatosis reduction has been observed in patients using SGLT2i. We highly recommend further research in this field, which we believe will eventually lead to a new indication for SGLT2i, i.e., MASLD.

RESUMEN

Background: The hepatic steatosis and fibrosis related to metabolic dysfunction-associated steatotic liver disease (MASLD) are important factors in the progression. The Multi echo three-dimensional (3D) Dixon sequence can obtain a single breath hold scan for a fat fraction map and an R2* map. The R2* value is usually used to evaluate iron deposition. Whether the change in R2* value is related to liver fibrosis after injection of gadolinium disulfide (Gd) should be noted. This study evaluates the value of enhanced magnetic relaxation time in the risk stratification of liver fibrosis by analyzing the changes in R2* before and after Gd enhancement, and explores the potential application of Multi echo 3D Dixon sequence in one-stop evaluation of MASLD. Methods: This retrospective study included 138 MASLD patients who underwent Gadolinum ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) magnetic resonance imaging (MRI) examination in The First Affiliated Hospital of Chongqing Medical University from June 2020 to December 2021. Finally, 90 subjects were divided into moderate and high-risk fibrosis group and low-risk fibrosis group by two-step assessment of liver fibrosis. Multi-echo 3D chemical shift imaging sequence (Q-Dixon) sequences and gradient-echo T1WI (Vibe-Dixon) sequence were performed during the non-enhanced phase and hepatobiliary phase, respectively, and then the signal-intensity enhancement (SE) and magnetic relaxation-time enhancement (RE) values were calculated. The interobserver correlation coefficient was used to evaluate the consistency between observers. Univariate t-test was used to analyze the differences in RE and SE of liver fibrosis among different risk levels. Delong analysis was performed on receiver operating characteristic (ROC) curve to evaluate the difference in diagnostic efficacy between RE and SE in differentiating the risk level of liver fibrosis. Results: Among the 90 patients, 55 (61.1%) belonged to the low-risk group and 35 (38.9%) belonged to the medium-to-high-risk group. The average RE and SE values were 1.23±0.15 and 1.57±0.23 in the low-risk group and 0.99±0.09 and 1.38±0.21 in both the medium-to-high-risk group (P<0.01). The ROC curve showed that the area under the curve (AUC) value of RE was 0.922, with a corresponding optimal threshold of 0.713, sensitivity of 0.852, and specificity of 0.861. The AUC value of SE was 0.724, with a corresponding optimal threshold of 0.352, sensitivity of 0.519, and specificity of 0.833. The AUC difference between RE and SE for the predictive value of different risk assessments was 0.198, and the 95% confidence interval of the difference was 0.084-0.312. The Delong test showed that the difference was significant (P<0.01). Conclusions: Magnetic RE had high effectiveness for distinguishing between liver-fibrosis risk levels. The combination of the Q-Dixon sequence and Gd-EOB-DTPA has the potential of one-stop evaluation of MASLD.

RESUMEN

The matrix metalloproteinase MMP14 is a ubiquitously expressed, membrane-bound, secreted endopeptidase that proteolyzes substrates to regulate development, signaling, and metabolism. However, the spatial and contextual events inciting MMP14 activation and its metabolic sequelae are not fully understood. Here, we introduce an inducible, hepatocyte-specific MMP14-deficient model (MMP14LKO mice) to elucidate cell-intrinsic and systemic MMP14 function. We show that hepatocyte MMP14 mediates diet-induced body weight gain, peripheral adiposity, and impaired glucose homeostasis and drives diet-induced liver triglyceride accumulation and induction of hepatic inflammatory and fibrotic gene expression. Single-nucleus RNA sequencing revealed that hepatocyte MMP14 mediates Kupffer cell and T-cell accumulation and promotes diet-induced hepatocellular subpopulation shifts toward protection against lipid absorption. MMP14 co-immunoprecipitation and proteomic analyses revealed MMP14 substrate binding across both inflammatory and cytokine signaling, as well as metabolic pathways. Strikingly, hepatocyte MMP14 loss-of-function suppressed skeletal muscle and adipose inflammation in vivo, and in a reductionist adipose-hepatocyte co-culture model. Finally, we reveal that trehalose-type glucose transporter inhibitors decrease hepatocyte MMP14 gene expression and nominate these inhibitors as translatable therapeutic metabolic agents. We conclude that hepatocyte MMP14 drives liver and inter-organ inflammatory and metabolic sequelae of obesogenic dietary insult. Modulating MMP14 activation and blockade thus represents a targetable node in the pathogenesis of hepatic inflammation.

RESUMEN

Background: Fatty liver index (FLI) and hepatic steatosis index (HSI) are serologic scores used to detect liver steatosis. However, their diagnostic performance in people with HIV (PWH) remains unclear. We performed an external validation of FLI and HSI in the Swiss HIV Cohort Study. Methods: We systematically performed vibration-controlled transient elastography (VCTE) among Swiss HIV Cohort Study participants at Bern University Hospital between November 2019 and August 2021. Individuals with viral hepatitis and pregnant women were excluded. We defined liver steatosis as controlled attenuation parameter ≥248 dB/m using VCTE. Model discrimination was assessed with the C-index and model calibration with calibration plots. A decision curve analysis was performed to compare the clinical usefulness of both scores. Results: Of 321 participants, 91 (28.4%) were female, the median age was 51.4 years (IQR, 42-59), 230 (71.7%) were Caucasian, and 164 (51.1%) had a body mass index >25 kg/m2. VCTE-confirmed liver steatosis was present in 158 (49.2%). Overall, 125 (38.9%) had an FLI ≥60, and 128 (39.9%) had an HSI ≥36. At these cutoffs, the C-index to diagnose liver steatosis was 0.85 for FLI (95% CI, .80-.89) and 0.78 for HSI (95% CI, .73-.83). Whereas FLI was well calibrated, HSI overestimated the risk for steatosis. Both models showed a positive net benefit, with FLI having a greater net benefit when compared with HSI. Conclusions: FLI and HSI are valid tools to detect liver steatosis in PWH. FLI should be the preferred score, given its better performance and greater clinical usefulness.

RESUMEN

Background and Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common cause of chronic liver disease worldwide. The current and projected cost of treating individuals with MASLD in Canada remains unknown. Our objective was to calculate the projected liver-specific and total health-care costs for people living with MASLD in Canada from 2020 to 2050. Methods: The health-care usage of a cohort of patients diagnosed with MASLD in Calgary, Alberta was calculated using administrative data. Liver-specific encounters were identified and the average costs per year per patient were calculated. Projected costs were calculated by multiplying the average cost per patient within each health state by the projected prevalence of each health state. Results: There were 6358 patients in the cohort. The annual average liver-specific cost per patient was $7.02 for F0/F1, $35.30 for F2, $60.46 for F3, and $72.55 for F4. The projected Canada-wide liver-specific cost was $85.5 million in 2020 and was expected to increase by $51 million by 2050. The average annual total health-care cost per patient was $397.90 for F0/F1, $781.53 for F2, $2881.84 for F3, and $1598.82 for F4. Thus, the projected Canada-wide total health-care cost was $3.76 billion in 2020 and was expected to increase by almost $2 billion by 2050. Conclusion: These estimates underscore the need for a MASLD framework that focuses on both prevention and innovative care models to change the predicted trajectory of health-care costs.

RESUMEN

Introduction: Following the introduction of metabolic dysfunction-associated steatotic liver disease (MASLD) as a replacement term for nonalcoholic fatty liver disease, the relationship between MASLD and cannabis use has yet to be established. With the global rise in cannabis consumption, understanding its impact on MASLD is critical for clinical guidance. Our study investigated the association between cannabis use, MASLD, and clinically significant fibrosis (CSF) among U.S. adults. Methods: Data were collected from the National Health and Nutrition Examination Survey for the period 2017 to 2018 to conduct a cross-sectional analysis. The diagnosis of hepatic steatosis and CSF was based on median values of the controlled attenuation parameter and liver stiffness measurement, with thresholds of 285 dB/m and 8.6 kPa, respectively. Information on cannabis use was obtained through self-report questionnaires. Multinomial logistic regression models and subgroup analyses were used to investigate the association between cannabis use and MASLD with CSF. Results: Our study assessed data from 2,756 U.S. adults (51.1% female; 32.2% white; mean age 39.41 ± 11.83 years), who had complete information on liver stiffness measurements through transient elastography alongside reported cannabis use. Results indicated that cannabis use overall was not associated with liver stiffness in patients with MASLD. However, among females, cannabis use was associated with MASLD accompanied by CSF, with an adjusted odds ratio (OR) of 0.47 (95% confidence interval [CI]: 0.24-0.91). Heavy cannabis use (9 to 30 times per month) was associated with MASLD accompanied by CSF among female participants, with an adjusted OR of 0.12 (95% CI: 0.02-0.88). Conclusion: In our study, cannabis use did not show a significant association with liver stiffness in patients diagnosed with MASLD. However, heavy cannabis consumption in women was associated with MASLD accompanied by CSF. These findings suggest that the effects of cannabis on liver health may differ based on gender and frequency of cannabis use, emphasizing the need for further research in this area.

RESUMEN

BACKGROUND: Currently, there remains ongoing controversy about the selection of postoperative antiviral drugs for hepatocellular carcinoma (HCC) patients with concurrent metabolic dysfunction-associated steatotic liver disease (MASLD) and hepatitis B virus (HBV) infection (HPMH) who underwent hepatectomy. METHOD: A multivariate Cox proportional hazards model and a propensity score matching (PSM) analysis were implemented to ensure equal baseline characteristics. The Kaplan‒Meier survival curves were employed for prognosis comparison between the two groups. RESULTS: This study included 225 HPMH who all received post-hepatectomy antiviral therapy; with 107 in the tenofovir disoproxil fumarate (TDF) group and 118 in the entecavir (ETV) group. In the entire cohort, according to the multivariate analysis, patients in the TDF group showed better recurrence-free survival (RFS) (HR = 0.78; 95% CI, 0.55-0.95; p = 0.030) and overall survival (OS) (HR = 0.52; 95% CI, 0.30-0.97; p = 0.021) than those in the ETV group. After executing a PSM analysis, Kaplan‒Meier survival curve analysis disclosed significant differences for both RFS and OS between the two groups (p = 0.03 and p = 0.01, respectively). CONCLUSIONS: In summary, our study suggests a more significant association of TDF in improving RFS and OS than ETV in HPMH who underwent hepatectomy through multivariate and PSM analysis. These findings indicate that the choice of antiviral drugs in HPHM holds crucial significance in guiding patient long-term prognosis.
