Interrelationship between physical activity and depression in nonalcoholic fatty liver disease

Factors Associated With Motivation to Reduce Alcohol Use Among Patients With Chronic Liver Disease

BACKGROUND AND AIMS

Alcohol use is prevalent among hepatology clinic patients with chronic liver disease (CLD). We explored factors associated with the importance and confidence dimensions of motivation to reduce drinking.

METHODS

Participants (N = 121) with unhealthy alcohol use (i.e., over NIH guidelines) receiving care in hepatology clinics from a safety-net hospital (SN, N = 54) and two Veterans Affairs Healthcare Systems (VA, N = 67) were enrolled in an alcohol intervention trial from March 2022 through October 2023. Baseline assessments included Generalised Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-8), Alcohol Use Disorders Identification Test (AUDIT), COVID-19 stress; and measures of importance and confidence to decrease alcohol use (readiness rulers, scales of 1-10). Liver disease aetiology and severity were extracted from electronic health records. We performed multivariable linear regression models with forward selection to assess pre-specified variables' associations with importance and confidence.

RESULTS

The sample was 84% male, 40% Latino, 31% White, 18% Black and 11% other races; median age was 61 years. Median (Q1-Q3) AUDIT score was 16 (12-24), importance was 9 (6-10) and confidence was 8 (5-9). On multivariable analysis, VA site (vs. SN) participants had a 0.97-point lower importance score (p = 0.02); higher symptoms of depression (PHQ-8 score ≥ 10 vs. < 10) and AUDIT scores (for each point increase) were associated with higher importance score (estimates 1.2 and 0.08, p < 0.05, respectively). Liver disease aetiology and severity were not significantly associated with outcomes.

CONCLUSIONS

Depression, alcohol problem severity and treatment site may influence motivation to reduce alcohol use and could inform future hepatology-based interventions.

A comprehensive review of patient-reported outcomes in metabolic dysfunction-associated steatotic liver disease

The global prevalence of obesity and type 2 diabetes has increased, contributing to an increased worldwide prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD). Currently, one in three adults is affected by MASLD and/or its progressive form, metabolic dysfunction-associated steatohepatitis (MASH), making this liver disease a significant public health challenge. Along with MASH-related cirrhosis, these conditions are poised to become the leading causes of chronic liver disease and liver transplants in the near future. Given the growing burden of MASLD and MASH, it is crucial to understand their impact from the patients’ perspective. One way to do this is by assessing patient-reported outcomes (PROs), including health-related quality of life (HRQL). HRQL can be assessed using generic instruments like the short form 36 version (SF-36) and the European quality of life-5 dimensions questionnaire (EQ-5D), or disease-specific tools such as the chronic liver disease questionnaire for nonalcoholic steatohepatitis (CLDQ-NASH). Given the limitations of each instrument, the best approach generally involves using both generic and disease-specific instruments. Evidence indicates that HRQL scores are significantly lower in individuals with MASLD, especially in areas assessing physical activity and the ability to perform daily living tasks. Fatigue and impaired work productivity are also important PROs for those with MASLD/MASH. These decrements in PROs worsen with disease progression but appear to improve with disease regression, including improvements linked to treatment. In this context, measuring PROs enhances the assessment of other patient-centric outcomes and provides insights for the healthcare community to develop interventions that could improve both clinical and humanistic outcomes for individuals living with MASLD/MASH.

Anxiety and depression in metabolic-associated steatotic liver disease: relation with socio-demographic features and liver disease severity

PURPOSE

We aimed to evaluate the prevalence of anxiety and depression traits in Italian patients with metabolic dysfunction-associated steatotic liver disease (MASLD), and the possible relation with the severity of liver disease.

METHODS

Demographic, anthropometric, clinical and laboratory parameters were collected in patients referred to a metabolic unit for a comprehensive evaluation of possible liver disease. Hepatic steatosis and fibrosis were evaluated by surrogate biomarkers. Imaging (controlled attenuation parameter-CAP and vibration-controlled transient elastography-VCTE). Beck depression inventory (BDI) and state-trait anxiety inventory-Y (STAI-Y) were used to define depressive/anxiety states; calorie intake and lifestyle were self-assessed by questionnaires.

RESULTS

The whole sample comprised 286 patients (61.9% females; mean age 52.0 years; BMI, 34.6 kg/m2); 223 fulfilled MASLD criteria. BDI and trait anxiety scores were lower in the MASLD cohort, and the prevalence of both moderate/severe depression and severe trait anxiety was reduced compared with non-MASLD cases, despite VCTE-diagnosed fibrosis F3-F4 present in over 15% of cases. However, after correction for demographic and anthropometric confounders, MASLD was not associated with a lower risk of moderate/severe depression or severe anxiety trait (odds ratio, 0.34; 95% confidence interval, 0.12-1.01 and 0.79, 0.27-2.34). Additional adjustment for the severity of fibrosis did not change the results. No differences in state anxiety were observed.

CONCLUSION

The risk of anxiety and depression in MASLD is not different from that generated by diabetes and obesity per se. MASLD patients do not perceive liver disease as a specific source of psychological distress, possibly as a consequence of the unawareness of progressive liver disease.

Understanding the Burden of Nonalcoholic Fatty Liver Disease: Time for Action

The prevalence of nonalcoholic fatty liver disease (NAFLD) in the United States is 38%, having increased by 50% within the past 3 decades. The estimated NAFLD prevalence among people with type 2 diabetes is 55-70%. The presence of type 2 diabetes is associated with a higher likelihood of progression of NAFLD to fibrosis development, liver transplant, and death. Cardiovascular disease is the main cause of mortality among people with NAFLD, and the risk of death is significantly higher in people with both NAFLD and type 2 diabetes. NAFLD carries high patient and economic burdens but low awareness among both the general public and health care providers. This article reviews the epidemiology of NAFLD and discusses the need for appropriate risk stratification, referral for specialty care, management of cardiometabolic risk factors, and treatment of the disease. The authors present a call to action to raise awareness of NAFLD and address its increasing burden in a systematic and efficient manner.

Hypertension is prevalent in non-alcoholic fatty liver disease and increases all-cause and cardiovascular mortality

Background and aims

Hypertension (HTN) is a common comorbidity in non-alcoholic fatty liver disease (NAFLD) affecting up to 40% of individuals. However, the impact of HTN and its control on outcomes in NAFLD remains unclear. Therefore, we aimed to examine the impact of HTN on survival outcomes in a longitudinal cohort of NAFLD patients.

Methods

The analysis consisted of adults in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018 with data on socio-demographic characteristics and comorbidities. NAFLD was diagnosed with fatty liver index (FLI) and United States-FLI at a cut-off of 60 and 30, respectively in the substantial absence of alcohol use. A multivariate regression analysis was conducted to adjust for confounders.

Results

A total of 45,302 adults were included, and 27.83% were identified to have NAFLD. Overall, 45.65 and 35.12% of patients with NAFLD had HTN and uncontrolled HTN, respectively. A multivariate analysis with confounders demonstrated that hypertensive NAFLD had a significantly increased risk of all-cause mortality (HR: 1.39, CI: 1.14-1.68, p < 0.01) and cardiovascular disease (CVD) mortality (HR: 1.85, CI: 1.06-3.21, p = 0.03). Untreated HTN remained to have a significantly increased risk in all-cause (HR: 1.59, CI: 1.28-1.96, p < 0.01) and CVD mortality (HR: 2.36, CI: 1.36-4.10, p < 0.01) while treated HTN had a non-significant increased risk of CVD mortality (HR: 1.51, CI: 0.87-2.63, p = 0.14) and a lower magnitude of increase in the risk of all-cause mortality (HR: 1.26, CI: 1.03-1.55, p = 0.03).

Conclusion

Despite the significant burden of HTN in NAFLD, up to a fifth of patients have adequate control, and the lack thereof significantly increases the mortality risk. With the significant association of HTN in NAFLD, patients with NAFLD should be managed with a multidisciplinary team to improve longitudinal outcomes.
