Frailty as tested by the Liver Frailty Index in out-patient patients with cirrhosis in China: a cross-sectional study

The prevalence and characteristics of frailty in cirrhosis patients: a meta-analysis and systematic review

Objectives

This study aimed to assess the prevalence of frailty in cirrhosis patients and the distribution of age, sex, and body mass index (BMI) in cirrhotic patients with frailty.

Methods

We performed a thorough literature search using PubMed, Embase, Web of Science, and the Cochrane Library from inception to 29 February 2024. The estimated prevalence with a 95% confidence interval (CI) was calculated with a random effect model. Subgroup analysis and sensitivity analysis were performed to assess the heterogeneity and characterize the distribution of age, sex, and body mass index (BMI) in cirrhotic patients. Publication bias was assessed by the funnel plot, Begg's test, and Egger's test.

Results

The 16 included studies, which were all observational, reported a prevalence of frailty in 8,406 cirrhosis patients ranging from 9 to 65%, and the overall estimated prevalence was 27% (95% CI: 21-33%; I2 = 97.7%, P < 0.001). This meta-analysis indicated that the estimated prevalence of frailty in cirrhosis patients was high, and compared to the non-frail cohort, the frail cohort tended to have a higher mean age, with a mean age of 63.3 (95% CI: 59.9, 66.7; Z = 36.48; P < 0.001), and a larger proportion of male patients with worse liver function, with a mean of 73.5% (95% CI: 71.4, 75.5%; Z = 7.65; P < 0.001), ND in the frail cohort, 54.8% (95% CI: 43.1, 66.5%; P < 0.001) and 23.4% (95% CI: 13.2, 33.7%; P < 0.001) were classified into Child-Pugh B and C, respectively. Meanwhile, the patients in the non-frail cohort are more likely to have a higher BMI, with a mean of 28.4 (95% CI: 24.1, 32.7; Z = 13.07; P < 0.001).

Conclusion

The current study suggests that cirrhosis patients have a high prevalence of frailty. Compared with the non-frail cohort, the frail patients tend to be male, older, and have a lower BMI with worse liver function.

Association of frailty with activity levels and sedentary behaviours in patients with hepatitis B cirrhosis: A cross-sectional study

BACKGROUND AND AIMS

Research on the association between activity levels and sedentary behaviour with frailty in patients affected by hepatitis B cirrhosis is sparse. This study aimed to explore the association of frailty with activity levels and sedentary behaviours in patients with hepatitis B cirrhosis.

DESIGN

This cross-sectional study followed the STROBE checklist.

METHODS

This study was conducted in Guangzhou, China, between August 2021 and October 2022. The frailty condition of patients with hepatitis B cirrhosis was assessed using the liver frailty index (LFI). Their physical activity levels and sedentary time were assessed using the International Questionnaire of Physical Activity. Pearson correlation and binary logistic regression were used to analyse the data.

RESULTS

Among the 503 patients with hepatitis B cirrhosis in the final analysis, 107 (21.3%) were identified as frail. Frailty was negatively correlated with walking time (r = -0.174, p < 0.001), moderate-intensity activity time (r = -0.185, p < 0.001), high-intensity activity time (r = -0.243, p < 0.001) and total activity time (r = -0.256, p < 0.001). Patients with insufficient activity (<150 min/week) and sedentary behaviour (≥420 min/day) were found to have 2.829 times higher risk of frailty than those with sufficient activity (≥150 min/week) and no sedentary behaviour (<420 min/day) (95% CI: 1.380, 5.799).

CONCLUSION

Patients with hepatitis B cirrhosis who exhibited frailty demonstrated limited physical activity and engaged in sedentary behaviours.

NO PATIENT OR PUBLIC CONTRIBUTION

Patients with hepatitis B cirrhosis contributed their data to the study.

Frailty in end-stage liver disease: Understanding pathophysiology, tools for assessment, and strategies for management

Frailty and sarcopenia are frequently observed in patients with end-stage liver disease. Frailty is a complex condition that arises from deteriorations across various physiological systems, including the musculoskeletal, cardiovascular, and immune systems, resulting in a reduced ability of the body to withstand stressors. This condition is associated with declined resilience and increased vulnerability to negative outcomes, including disability, hospitalization, and mortality. In cirrhotic patients, frailty is influenced by multiple factors, such as hyperammonemia, hormonal imbalance, malnutrition, ascites, hepatic encephalopathy, and alcohol intake. Assessing frailty is crucial in predicting morbidity and mortality in cirrhotic patients. It can aid in making critical decisions regarding patients' eligibility for critical care and transplantation. This, in turn, can guide the development of an individualized treatment plan for each patient with cirrhosis, with a focus on prioritizing exercise, proper nutrition, and appropriate treatment of hepatic complications as the primary lines of treatment. In this review, we aim to explore the topic of frailty in liver diseases, with a particular emphasis on pathophysiology, clinical assessment, and discuss strategies for preventing frailty through effective treatment of hepatic complications. Furthermore, we explore novel assessment and management strategies that have emerged in recent years, including the use of wearable technology and telemedicine.
