ABSTRACT
BACKGROUND AND AIMS: No medication has been found to reduce liver-related events. We evaluated the effect of sodium-glucose cotransporter-2 inhibitor (SGLT2i) on liver-related outcomes. APPROACH AND RESULTS: Single nucleotide polymorphisms associated with SGLT2 inhibition were identified, and a genetic risk score (GRS) was computed using the UK Biobank data (n=337,138). Two-sample Mendelian randomization (MR) was conducted using the FinnGen (n=218,792) database and the UK Biobank data. In parallel, a nationwide population-based study using the Korean National Health Insurance Service (NHIS) database was conducted. The development of liver-related complications (ie, hepatic decompensation, HCC, liver transplantation, and death) was compared between individuals with type 2 diabetes mellitus and steatotic liver diseases treated with SGLT2i (n=13,208) and propensity score-matched individuals treated with dipeptidyl peptidase-4 inhibitor (n=70,342). After computing GRS with 6 single nucleotide polymorphisms (rs4488457, rs80577326, rs11865835, rs9930811, rs34497199, and rs35445454), GRS-based MR showed that SGLT2 inhibition (per 1 SD increase of GRS, 0.1% lowering of HbA1c) was negatively associated with cirrhosis development (adjusted odds ratio=0.83, 95% CI=0.70-0.98, p =0.03) and this was consistent in the 2-sample MR (OR=0.73, 95% CI=0.60-0.90, p =0.003). In the Korean NHIS database, the risk of liver-related complications was significantly lower in the SGLT2i group than in the dipeptidyl peptidase-4 inhibitor group (adjusted hazard ratio=0.88, 95% CI=0.79-0.97, p =0.01), and this difference remained significant (adjusted hazard ratio=0.72-0.89, all p <0.05) across various sensitivity analyses. CONCLUSIONS: Both MRs using 2 European cohorts and a Korean nationwide population-based cohort study suggest that SGLT2 inhibition is associated with a lower risk of liver-related events.
ABSTRACT
BACKGROUND: Gut microbial dysbiosis is implicated in chronic liver disease and hepatocellular carcinoma (HCC), but the role of microbiomes from various body sites remains unexplored. We assessed disease-specific alterations in the urinary microbiome in HCC patients, investigating their potential as diagnostic biomarkers. METHODS: We performed cross-sectional analyses of urine samples from 471 HCC patients and 397 healthy controls and validated the results in an independent cohort of 164 HCC patients and 164 healthy controls. Urinary microbiomes were analyzed by 16S rRNA gene sequencing. A microbial marker-based model distinguishing HCC from controls was built based on logistic regression, and its performance was tested. RESULTS: Microbial diversity was significantly reduced in the HCC patients compared with the controls. There were significant differences in the abundances of various bacteria correlated with HCC, thus defining a urinary microbiome-derived signature of HCC. We developed nine HCC-associated genera-based models with robust diagnostic accuracy (area under the curve [AUC], 0.89; balanced accuracy, 81.2%). In the validation, this model detected HCC with an AUC of 0.94 and an accuracy of 88.4%. CONCLUSIONS: The urinary microbiome might be a potential biomarker for the detection of HCC. Further clinical testing and validation of these results are needed in prospective studies.

Different antiviral treatments for chronic hepatitis B (CHB) have been known to have different metabolic effects. This study aimed to reveal whether tenofovir alafenamide (TAF)-induced dyslipidemia and its associated outcomes are significant. This study utilized 15-year historical cohort including patients with CHB in Korea and consisted of two parts: the single-antiviral and switch-antiviral cohorts. In the single-antiviral cohort, patients were divided into four groups (entecavir [ETV]-only, tenofovir disoproxil fumarate [TDF]-only, TAF-only, and non-antiviral). Propensity score matching (PSM) and linear regression model were sequentially applied to compare metabolic profiles and estimated atherosclerotic cardiovascular disease (ASCVD) risks longitudinally. In the switch-antiviral cohort, pairwise analyses were conducted in patients who switched NAs to TAF or from TAF. In the single-antiviral cohort, body weight and statin use showed significant differences between groups before PSM, but well-balanced after PSM. Changes in total cholesterol were significantly different between groups (-2.57 mg/dL/year in the TDF-only group and +2.88 mg/dL/year in the TAF-only group; p = 0.002 and p = 0.02, respectively). In the TDF-only group, HDL cholesterol decreased as well (-0.55 mg/dL/year; p < 0.001). The TAF-only group had the greatest increase in ASCVD risk, followed by the TDF-only group and the non-antiviral group. In the switch-antiviral cohort, patients who switched from TDF to TAF had a higher total cholesterol after switching (+9.4 mg/dL/year) than before switching (-1.0 mg/dL/year; p = 0.047). Sensitivity analysis on data with an observation period set to a maximum of 3 years for NA treatment showed consistent results on total cholesterol (-2.96 mg/dL/year in the TDF-only group and +3.09 mg/dL/year in the TAF-only group; p = 0.001 and p = 0.005, respectively). Another sensitivity analysis conducted on statin-treated patients revealed no significant change in cholesterol and ASCVD risk. TAF was associated with increased total cholesterol, whereas TDF was associated with decreased total and HDL cholesterol. Both TAF and TDF were associated with increased ASCVD risks, and statin use might mitigate these risks.

BACKGROUND AND AIMS: Metabolic dysfunction-associated fatty liver disease (MAFLD) encompasses heterogeneous fatty liver diseases associated with metabolic disorders. We aimed to evaluate the association between MAFLD and extrahepatic malignancies based on MAFLD subtypes. METHODS: This nationwide cohort study included 9 298 497 patients who participated in a health-screening programme of the National Health Insurance Service of Korea in 2009. Patients were further classified into four subgroups: non-MAFLD, diabetes mellitus (DM)-MAFLD, overweight/obese-MAFLD and lean-MAFLD. The primary outcome was the development of any primary extrahepatic malignancy, while death, decompensated liver cirrhosis and liver transplantation were considered competing events. The secondary outcomes included all-cause and extrahepatic malignancy-related mortality. RESULTS: In total, 2 500 080 patients were diagnosed with MAFLD. During a median follow-up of 10.3 years, 447 880 patients (6.0%) with extrahepatic malignancies were identified. The DM-MAFLD (adjusted subdistribution hazard ratio [aSHR] = 1.13; 95% confidence interval [CI] = 1.11-1.14; p < .001) and the lean-MAFLD (aSHR = 1.12; 95% CI = 1.10-1.14; p < .001) groups were associated with higher risks of extrahepatic malignancy than the non-MAFLD group. However, the overweight/obese-MAFLD group exhibited a similar risk of extrahepatic malignancy compared to the non-MAFLD group (aSHR = 1.00; 95% CI = .99-1.00; p = .42). These findings were reproduced in several sensitivity analyses. The DM-MAFLD was an independent risk factor for all-cause mortality (adjusted hazard ratio [aHR] = 1.41; 95% CI = 1.40-1.43; p < .001) and extrahepatic malignancy-related mortality (aHR = 1.20; 95% CI = 1.17-1.23; p < .001). CONCLUSION: The diabetic or lean subtype of MAFLD was associated with a higher risk of extrahepatic malignancy than non-MAFLD. As MAFLD comprises a heterogeneous population, appropriate risk stratification and management based on the MAFLD subtypes are required.

AIM: Antiviral treatment reduces the risk of developing hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. However, there is a lack of high-quality evidence regarding the preventive effects of tenofovir alafenamide (TAF) on HCC. We evaluated the impact of TAF use after curative treatment on HCC recurrence. METHODS: Patients who underwent surgery or radiofrequency ablation as a curative treatment for HCC were selected. Those patients who continued antiviral treatment with nucleos(t)ide analogs (NAs; entecavir [ETV] or tenofovir disoproxil fumarate [TDF]) or switched to TAF were included. The primary outcome was HCC recurrence, and the time-varying effect of NA use on HCC recurrence was analyzed using various statistical methods. RESULTS: Among 2794 consecutive patients with chronic hepatitis B who received curative treatment for HCC, 199 subsequently switched from ETV or TDF to TAF. After a median of 3.0 years, 1303 patients (46.6%) experienced HCC recurrence. After propensity score matching (ratio 1:10), switching to TAF was not associated with an increased HCC recurrence (HR 1.00, 95% CI 0.68-1.47; p = 1.00) by time-varying Cox analysis. Switching to TAF was not associated with HCC recurrence in subgroups of NA (HR 1.06, 95% CI 0.67-1.67; p = 0.81 for TDF, and HR 1.09, 95% CI 0.51-2.33; p = 0.82 for ETV). Kaplan-Meier analysis showed comparable HCC recurrence-free survival between patients who switched to TAF and those who continued with their NA (p = 0.08). Time-varying Cox analyses in various subgroups confirmed the primary findings. CONCLUSIONS: TAF is as effective as TDF and ETV in preventing HCC recurrence after curative treatment.
ABSTRACT
To address the shortcomings of current hepatocellular carcinoma (HCC) surveillance tests, we set out to find HCC-specific methylation markers and develop a highly sensitive polymerase chain reaction (PCR)-based method to detect them in circulating cell-free DNA (cfDNA). The analysis of large methylome data revealed that Ring Finger Protein 135 (RNF135) and Lactate Dehydrogenase B (LDHB) are universally applicable HCC methylation markers with no discernible methylation level detected in any other tissue types. These markers were used to develop Methylation Sensitive High-Resolution Analysis (MS-HRM), and their diagnostic accuracy was tested using cfDNA from healthy, at-risk, and HCC patients. The combined MS-HRM RNF135 and LDHB analysis detected 57% of HCC, outperforming the alpha-fetoprotein (AFP) test's sensitivity of 45% at comparable specificity. Furthermore, when used with the AFP test, the methylation assay can detect 70% of HCC. Our findings suggest that the cfDNA methylation assay could be used for HCC liquid biopsy.

BACKGROUND: Alcohol and diabetes are known risk factors for hepatocellular carcinoma (HCC); however, it is unclear whether the association between alcohol consumption and HCC risk differs by fasting serum glucose level and diabetes. We investigated the dose-response relationship between alcohol consumption and the risk of HCC according to glycemic status. METHODS AND FINDINGS: This population-based observational cohort study included patients who underwent general health checkups in 2009 using the Korean National Health Insurance Service Database. The primary outcome was HCC incidence, and Cox proportional hazard regression analysis was performed to estimate the relationship between alcohol consumption and HCC risk according to glycemic status. A total of 34,321 patients newly diagnosed with HCC were observed in the median follow-up period of 8.3 years. In the multivariable model, we adjusted for age, sex, smoking, regular exercise, income, hypertension, dyslipidemia, and body mass index. Mild-to-moderate alcohol consumption increased the risk of HCC in all glycemic statuses (normoglycemia: hazard ratio [HR], 1.06; 95% confidence interval [CI], 1.02 to 1.10; prediabetes: HR, 1.19; 95% CI, 1.14 to 1.24; and diabetes: HR, 2.02; 95% CI, 1.93 to 2.11) compared to normoglycemic nondrinking. Heavy alcohol consumption also increased the risk of HCC in all glycemic statuses (normoglycemia: HR, 1.39; 95% CI, 1.32 to 1.46; prediabetes: HR, 1.67; 95% CI, 1.58 to 1.77; and diabetes: HR, 3.29; 95% CI, 3.11 to 3.49) compared to normoglycemic nondrinking. Since alcohol consumption information in this study was based on a self-administered questionnaire, there may be a possibility of underestimation. Although we excluded patients with a history of viral hepatitis using diagnosis codes, we could not obtain information on hepatitis B or hepatitis C serum markers. CONCLUSIONS: Both mild-to-moderate and heavy alcohol consumption was associated with an increased risk of HCC in all glycemic statuses. The increased risk of HCC according to alcohol consumption was the highest in the diabetes group, suggesting that more intensive alcohol abstinence is required for patients with diabetes.

BACKGROUND: Metabolic-associated fatty liver disease (MAFLD) encompasses diverse disease groups with potentially heterogeneous clinical outcomes. We investigated the risk of all-cause and disease-specific mortality in MAFLD subgroups. METHODS: Using the Korean National Health Insurance Service database, participants were divided into four subgroups: no MAFLD, MAFLD-diabetes, MAFLD-overweight/obese, and MAFLD-lean. Hazard ratios (HRs) and 95% confidence interval (CI) values for all-cause and disease-specific mortality according to MAFLD subgroups were analyzed using Cox proportional hazards models. RESULTS: Among 9,935,314 participants, those with MAFLD-diabetes showed the highest risk of all-cause and disease-specific mortality. The HRs (95% CI) for all-cause mortality were 1.61 (1.59-1.63), 1.36 (1.34-1.38), and 1.19 (1.18-1.20) in the MAFLD-diabetes, MAFLD-lean, and MAFLD-overweight/obese groups, respectively. The magnitude of cardiovascular disease and cancer-related risk showed the same pattern. The risk of liver-related mortality in the MAFLD-lean group (HR: 2.84, 95% CI: 2.72-2.97) was comparable with that in the MAFLD-diabetes group (HR: 2.85, 95% CI: 2.75-2.95). When stratified by body mass index, liver-related mortality was the highest in MAFLD-lean individuals in the underweight group (HR, 5.03, 95% CI: 4.23-5.97). CONCLUSIONS: The MAFLD-lean and MAFLD-diabetes groups had a higher risk of all-cause and disease-specific mortality than did the MAFLD-overweight/obese group. Classifying MAFLD subgroups based on metabolic phenotypes might help risk stratification of patients with MAFLD.

BACKGROUND AND AIMS: Studies on differential effect of aspirin therapy on HCC risk across the spectrum of liver diseases are lacking. We investigated the association between aspirin use and risks of HCC, liver-associated death, and major bleeding in chronic hepatitis B (CHB) patients with or without cirrhosis. APPROACH AND RESULTS: We identified 329,635 eligible adults with CHB from 2007 through 2017, using the Korean National Health Insurance Service database, including patients who received aspirin for ≥90 consecutive days (n = 20,200) and patients who never received antiplatelet therapy (n = 309,435). Risks of HCC, liver-associated mortality, and major bleeding were estimated in a propensity-score-matched cohort (19,003 pairs), accounting for competing risks. With a median follow-up of 6.7 years, 10-year cumulative incidence of HCC was 9.5% in the aspirin-treated group and 11.3% in the untreated group (adjusted subdistribution hazard ratio [aSHR], 0.85; 95% CI, 0.78-0.92). However, among patients with cirrhosis (2479 pairs), an association of aspirin use with HCC risk was not evident (aSHR, 1.00; 95% CI, 0.85-1.18). Cirrhosis status had a significant effect on the association between aspirin use and HCC risk (pinteraction , n = 0.04). Aspirin use was also associated with lower liver-associated mortality (aSHR, 0.80; 95% CI, 0.71-0.90). Moreover, aspirin use was not associated with major bleeding risk (aSHR, 1.09; 95% CI, 0.99-1.21). CONCLUSIONS: Aspirin use was associated with reduced risks of HCC and liver-associated mortality in adults with CHB. Cirrhosis status had a substantial effect on the association between aspirin use and HCC risk.

Three-dimensional (3D) cell cultures have recently gained popularity in the biomedical sciences because of their similarity to the in vivo environment. SH-SY5Y cells, which are neuronal cells and are commonly used to investigate neurodegenerative diseases, have particularly been reported to be differentiated as neuron-like cells expressing neuron-specific markers of mature neurons in static 3D culture environments when compared to static 2D environments, and those in perfusion environments have not yet been investigated. Microfluidic technology has provided perfusion environment which has more similarity to in vivo through mimicking vascular transportation of nutrients, but air bubbles entering into microchannels drastically increase instability of the flow. Furthermore, static incubation commonly used is incompatible with perfusion setup due to its air conditions, which is a critical huddle to the biologists. In the present study, we developed a novel microfluidic perfusion 3D cell culture system that overcomes the disturbance from air bubbles and intuitionally sets the incubation with the perfusion 3D culture. The system is capable of generating concentration gradients between 5 and 95% and air bubble traps were included to increase stability during incubation by collecting air bubbles. To evaluate the perfusion 3D culture, SH-SY5Y differentiation was examined in static 2D, static 3D, and perfusion 3D cultures. Our system supported significantly increased clustering of SH-SY5Y compared to static 2D and 3D methods, as well as increasing neurite growth rate. This novel system therefore supports differentiation of SH-SY5Y and can be used to more accurately model the in vivo environment during cell culture experiments.

BACKGROUND: Rituximab occasionally induces reactivation of hepatitis B virus (HBV) in patients with resolved HBV, at times with fatal consequences. The optimal duration of prophylactic antiviral therapy in this situation is unclear. We aimed to investigate the difference in HBV reactivation according to the duration of prophylactic tenofovir disoproxil fumarate (TDF) in patients with resolved HBV and receiving rituximab. METHODS: A multicenter, randomized, open-label, prospective study was conducted in hepatitis B surface antigen-negative and anti-HBc-positive non-Hodgkin's lymphoma patients treated with rituximab-based chemotherapy. A total of 90 patients were randomized and received prophylactic TDF from the initiation of rituximab until 6 months (the 6-month group) or 12 months (the 12-month group) after the completion of rituximab. The primary outcome was the difference in HBV reactivation and the secondary outcomes were the difference in hepatitis flare and adverse events between the two groups. RESULTS: In an intention to treat (ITT) analysis, HBV reactivation occurred in 1 of 43 patients (2.3%; 95% confidence interval [CI], 0.41-12%) at a median of 13.3 months in the 6-month group and 2 of 41 patients (4.9%; 95% CI, 1.4-16%) at a median of 13.7 months in the 12-month group. In a per protocol (PP) analysis, HBV reactivation occurred in 1 of 18 patients (5.6%; 95% CI, 0.99-26%) at 13.3 months in the 6-month group and 1 of 13 patients (7.7%; 95% CI, 1.4-33%) at 9.7 months in the 12-month group. The cumulative incidence of HBV reactivation was not significantly different between the two groups in ITT and PP analyses (P = 0.502 and 0.795, respectively). The occurrence of adverse events was not significantly different between the two groups in ITT (9.3% in the 6-month group, 22.0% in the 12-month group, P = 0.193) and PP analyses (5.6% in the 6-month group, 7.7% in the 12-month group, P > 0.999). CONCLUSION: Prophylactic TDF up to 6 months after completion of rituximab-based chemotherapy is sufficient in terms of the efficacy and safety of reducing HBV reactivation in patients with resolved HBV. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02585947.

Alzheimer's disease (AD) is a neurodegenerative disease, associated with progressive cognitive impairment and memory loss. In the present study, we examined the protective effects of paeoniflorin against memory loss and cognitive decline in lipopolysaccharide (LPS)-induced mice. Treatment with paeoniflorin alleviated LPS-induced neurobehavioral dysfunction, as confirmed by behavioral tests, including the T-maze test, novel-object recognition test, and Morris water maze test. LPS stimulated the amyloidogenic pathway-related proteins (amyloid precursor protein, APP; ß-site APP cleavage enzyme, BACE; presenilin1, PS1; presenilin2, PS2) expression in the brain. However, paeoniflorin decreased APP, BACE, PS1, and PS2 protein levels. Therefore, paeoniflorin reverses LPS-induced cognitive impairment via inhibition of the amyloidogenic pathway in mice, which suggests that paeoniflorin may be useful in the prevention of neuroinflammation related to AD.

This study aims to investigate the protective effects and mechanisms of pectolinarin against oxidative stress-induced cell damage in SH-SY5Y cells. Neurodegenerative diseases-such as Alzheimer's disease-are potentially associated with oxidative stress, which causes excessive production of reactive oxygen species (ROS) that damage DNA and proteins in neuronal cells. The results of this study demonstrate that pectolinarin can scavenge hydroxyl and nitric oxide radicals in a concentration-dependent manner. Moreover, pectolinarin significantly increased cell viability while reducing ROS production and LDH release in the hydrogen peroxide (H2O2)-induced control group. Additionally, Pectolinarin recovered protein expression from H2O2-altered levels back to close-to-normal SH-SY5Y cell levels for components of the oxidative stress, inflammation, and apoptosis pathways-such as nuclear factor erythroid 2-related factor 2 (Nrf2), kelch-like ECH-associated protein (Keap1), anti-heme oxygenase 1 (HO-1), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-1ß (IL-1ß), B-cell lympho-ma-2 (Bcl-2) protein, and Bcl-2-associated X protein (Bax). These findings suggest that pectolinarin has the potential to be used as a plant material for functional foods to be applied in the treatment of neurodegenerative diseases, such as Alzheimer's disease, by mitigating oxidative stress-induced damage to neuronal cells.

PURPOSE: This concept analysis clarified "uncertainty in people with mental disabilities". METHODS: The research was conducted using Walker & Avant's conceptual analysis methodology. RESULTS: Uncertainty in people with mental disabilities showed the defining attributes of "ambiguity," "unpredictability," "distrust," and "lack of insight into illness," of which "distrust" and "lack of insight" were unique to people with mental disabilities. Accordingly, it was defined as a state in which it is difficult to determine the treatment's timing because (1) the disease process is often too ambiguous to make a decision; (2) abnormal behavior can recur at any time while the patients are under treatment and in recovery; and (3) patients struggle to accept the illness, tend to distrust healthcare professionals and family, and show lack of knowledge, making them miss their treatment's timing and even making the expectation for recovery vague. CONCLUSION: The attributes of uncertainty in people with mental disabilities identified in this study confirmed that mental health professionals should proactively intervene to treat patients at an appropriate time and continuously manage them to prevent recurrence. PRACTICE IMPLICATION: The study findings can be utilized in mental health research and in developing interventions to reduce uncertainty in people with mental disabilities, helping them recover and integrate into the community.

BACKGROUND AND AIMS: Long-term antiviral therapy can effectively suppress viral replication and improve clinical outcomes in patients with chronic hepatitis B (CHB), but it cannot eliminate risk of HCC. We investigated the association of metabolic risk factors with the risks of cancer and all-cause mortality in patients with CHB. APPROACH AND RESULTS: This nationwide population-based study from the Korean National Health Insurance Service database consisted of adults with CHB who underwent health examinations from 2007 through 2012. We collected baseline data on metabolic risk factors, including obesity, high blood pressure, hypercholesterolemia, and diabetes. The risks of developing HCC, non-HCC cancer, and overall death were analyzed according to the metabolic risk profile. The study population composed of 317,856 patients (median age, 46 years [interquartile range, 37-54 years]; 219,418 men [69.0%]) had 2,609,523.8 person-years of follow-up. A total of 18,850 HCCs, 22,164 non-HCC cancers, and 15,768 deaths were observed during a median follow-up period of 8.5 years. The metabolic risk factor burden was positively associated with the risks of HCC, non-HCC cancer, and all-cause mortality (all P < 0.0001 for trend). Patients with ≥3 metabolic risk factors, compared with those without metabolic risk factors, showed adjusted hazard ratios of 1.23 (95% CI, 1.16-1.31) for HCC, 1.34 (95% CI, 1.27-1.41) for non-HCC cancer, and 1.31 (95% CI, 1.23-1.39) for all-cause mortality. Among patients receiving antiviral therapy for over 5 years, the risk-increasing association of the sum of metabolic risk factors with the risks of HCC and overall death was consistent. CONCLUSION: The metabolic risk factor burden was associated with increased risks of HCC, non-HCC cancer, and all-cause mortality in patients with CHB.

BACKGROUND: Type 2 diabetes and non-alcoholic fatty liver disease (NAFLD) commonly coexist. However, NAFLD's effect on mortality in Asian patients with type 2 diabetes awaits full elucidation. Therefore, we examined NAFLD-related all-cause and cause-specific mortality in a nationwide Asian population with type 2 diabetes. METHODS: We included patients who had undergone general health checkups between 2009 and 2012 using the National Health Insurance Service database linked to death-certificate data. Hepatic steatosis was defined as a fatty liver index (FLI) ≥ 60, and advanced hepatic fibrosis was determined using the BARD score. FINDINGS: During the follow-up period of 8.1 years, 222,242 deaths occurred, with a mortality rate of 14.3/1000 person-years. An FLI ≥ 60 was significantly associated with increased risks of all-cause and cause-specific mortality including cardiovascular disease (CVD)-, cancer-, and liver disease (FLI ≥ 60: hazard ratio [HR] = 1.02, 95% confidence interval [CI] 1.01-1.03 for all-cause; 1.07, 1.04-1.10 for CVD; 1.12, 1.09-1.14 for cancer; and 2.63, 2.50-2.77 for liver disease). Those with an FLI ≥ 60 and fibrosis (BARD ≥ 2) exhibited increased risks of all-cause (HR, 95% CI 1.11, 1.10-1.12), CVD- (HR, 95% CI 1.11, 1.09-1.14), cancer- (HR, 95% CI 1.17, 1.15-1.19), and liver disease-related (HR, 95% CI 2.38, 2.29-2.49) mortality. CONCLUSION: Hepatic steatosis and advanced fibrosis were significantly associated with risks of overall and cause-specific mortality in patients with type 2 diabetes. Our results provide evidence that determining the presence of hepatic steatosis and/or fibrosis potentially plays a role in risk stratification of mortality outcomes in patients with type 2 diabetes mellitus.

BACKGROUND & AIMS: This multicenter cohort study aimed to compare the real-world biochemical response rates during tenofovir alafenamide (TAF), tenofovir disoproxil fumarate (TDF), and entecavir (ETV) treatment in chronic hepatitis B virus (HBV) infection patients. METHODS: Overall, 1282 treatment-naïve patients with CHB who commenced TAF (n = 270), TDF (n = 617), or ETV (n = 395) were analysed for biochemical response rates during the antiviral treatment using a time-dependent Cox proportional hazard model after the inverse probability of treatment weighting (IPTW). RESULTS: Patients treated with ETV were older (55.1 ± 11.5 years) than TAF or TDF (P < .0001). ETV was more frequently prescribed to patients with diabetes mellitus (DM, P = .003), hypertension (P < .0001), chronic kidney disease (P < .0001), and negative e-antigen (P < .0001). Cumulative biochemical response rate was independently lower in patients with radiologic fatty liver (HR, 0.75; 95% CI, 0.61-0.94) and obese patients without DM (HR, 0.85; 95% CI, 0.68-0.98) according to multivariable Cox analyses based on time-dependent variables after IPTW for age, sex, liver cirrhosis, baseline e-antigen, ALT, and HBV DNA levels. ETV treated patients (HR, 1.38; 95% CI, 1.13-1.68) showed higher biochemical response rates compared with TAF- or TDF-treated patients after adjusting for similar parameters. CONCLUSIONS: In real-world practice, ETV was preferable for older, hepatitis B e-antigen negative patients with underlying comorbidities. Biochemical responses in patients treated with ETV, TAF, and TDF were significantly affected by metabolic factors such as fatty liver, obesity, and DM. However, the mechanism behind the higher biochemical response rate in patients treated with ETV should be investigated further.

AIM: To investigate the relationship between nonalcoholic fatty liver disease (NAFLD) and cardiovascular events among a nationally representative sample of young adults in Korea. METHODS AND RESULTS: This population-based cohort study from the Korean National Health Insurance Service included adults who were aged 20 to 39 years when they underwent a health examination between 2009 and 2012. NAFLD was defined as a fatty liver index (FLI) ≥60, and participants were divided into three groups according to FLI (<30, 30-59 and ≥60) to investigate the dose-dependent effect of FLI score. Among 5 324 410 participants, 9.8% had an FLI ≥60. There were 13 051 myocardial infarctions (MIs; 0.39%) and 8573 strokes (0.26%) during a median follow-up of 8.4 years. In multivariable analysis, NAFLD was associated with a higher risk of MI and stroke (hazard ratio [HR] 1.69, 95% confidence interval [CI] 1.61-1.77 and HR 1.73, 95% CI 1.63-1.84, respectively). MI and stroke had dose-dependent relationships with FLI (HR 1.28 in participants with FLI 30-59 and 1.73 in those with FLI ≥60 for MI and HR 1.18 in participants with FLI 30-59 and 1.41 in those with FLI ≥60 for stroke, respectively). CONCLUSIONS: Nonalcholic fatty liver disease was an independent predictor of MI and stroke in young adults. These results suggest that primary prevention of cardiovascular disease should be emphasized in young adults with NAFLD.

BACKGROUND/AIM: In a randomized controlled trial, lenvatinib was non-inferior to sorafenib in overall survival (OS) of patients with unresectable hepatocellular carcinoma (uHCC). This study aimed to compare the effects of sorafenib and lenvatinib as first-line systemic therapy against uHCC with real-world data in chronic hepatitis B patients. METHODS: This retrospective single-center study involved 132 patients with HBV-related uHCC. Propensity score matching (PSM) was used to balance the baseline characteristics, including age, sex, serum alpha-fetoprotein levels, Child-Pugh class, tumor size, and tumor stage. The primary endpoint was overall survival (OS), and the secondary endpoints included progression-free survival (PFS), time to progression (TTP), and tumor response. RESULTS: After PSM, the final analysis included 44 patients treated with lenvatinib and 88 with sorafenib. The OS (7.0 vs 9.2 months, p = 0.070) and PFS (4.6 vs 2.4 months, p = 0.134) were comparable between the two drugs. Multivariable analysis showed that lenvatinib and sorafenib were not independent prognostic factors of OS (adjusted hazard ratio = 1.41, 95% confidence interval = 0.96-2.08, p = 0.077) after adjustment for baseline alpha-fetoprotein levels, total bilirubin levels, alanine aminotransferase level, performance status, tumor stage, and tumor size. However, the lenvatinib group had a significantly prolonged TTP (5.2 vs 2.5 months, p = 0.018) and a higher objective response rate (18.2% vs 4.5%, p = 0.020) and disease control rate (77.3% vs 47.7%, p = 0.001) than the sorafenib group. CONCLUSIONS: Our study demonstrated that lenvatinib had a comparable OS and PFS but longer TTP and better tumor response compared to sorafenib in patients with HBV-related uHCC.

BACKGROUND/AIM: Lenvatinib and sorafenib are currently available to treat patients with advanced hepatocellular carcinoma (HCC). However, since the clinical trials evaluating the efficacy of lenvatinib and sorafenib included only patients with Child-Pugh class A, little is known about the effectiveness of the treatments in patients with hepatic decompensation. We compared the effectiveness of lenvatinib and sorafenib in decompensated patients with unresectable HCC. METHODS: Consecutive patients who were classified as Child-Pugh class B or C and received lenvatinib or sorafenib as first-line systemic therapy for unresectable HCC between November 2018 and April 2020 at a tertiary referral center were included in this retrospective study. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS), time-to-progression, best overall tumor response, and safety profiles. RESULTS: Among 94 patients, 34 received lenvatinib and 60 received sorafenib. The median OS was 4.1 months (95% confidence interval [CI], 2.9-5.2): 4.2 months (95% CI, 2.9-5.3) for lenvatinib and 4.1 months (95% CI, 2.7-6.4) for sorafenib. The treatment regimen was not associated with significant improvement in OS after adjusting for covariables (adjusted hazard ratio [aHR], 0.92; 95% CI, 0.54-1.54; P = 0.74). The treatment regimen was not an independent predictor of PFS (lenvatinib vs. sorafenib; aHR, 0.77; 95% CI, 0.48-1.24; P = 0.28). HRs were maintained even after balancing with the inverse probability treatment weighting method. Objective response rates were 11.8% and 6.7% in patients receiving lenvatinib and sorafenib, respectively (P = 0.45). Ten patients in both groups (five in the lenvatinib group and five in the sorafenib group) underwent dose modification due to adverse events, and significant difference was not observed between the treatment groups (P = 0.49). CONCLUSION: The effectiveness of lenvatinib and sorafenib was comparable for the treatment of unresectable HCC in decompensated patients.
