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

A pilot clinical trial of exercise program for elderly patients with cirrhosis and frailty: comprehensive exercise rehabilitation intervention

BACKGROUND AND AIM

Comprehensive exercise rehabilitation has the potential to increase muscle mass and performance by stimulating protein synthesis and accelerating muscle catabolism. We developed the comprehensive exercise rehabilitation intervention (CERI) for elderly patients with cirrhosis, and we aimed to evaluate the safety and efficacy of CERI.

METHODS

Eligible were elderly patients with cirrhosis and frailty. Patients were randomized 1 : 1 to 12 weeks of CERI. Physical function were assessed using the gait speed, grip strength, 5 Sit-down Tests, and Balance Test, respectively.

RESULTS

Finally, 58 and 58 completed the study in CERI and SOC arms, respectively. The age range is 60-73. After 12 weeks, gait speed improved from 0.89 to 1.06 in CERI participants (Δgait speed 0.17) and 0.87-0.91 (Δgait speed 0.04) in SOC arm ( P  = 0.001 for Δgait speed difference). Grip strength improved from 15.44 to 15.94 in CERI participants (Δgrip strength 0.50) and 15.52-15.16 (Δgrip strength -0.36) in SOC arm ( P  = 0.044 for Δgrip strength difference). 5 Sit-down Tests Score improved from 16.17 to 15.46 in CERI participants (Δ5 Sit-down Tests 0.71) and 16.78-16.61 (Δ5 Sit-down Tests 0.17) in SOC arm ( P  = 0.037 for Δ5 Sit-down Tests difference). Median Balance Test score improved from 26.11 to 28.82 in CERI participants (ΔBalance Test 2.71) and 25.94-26.13 (ΔBalance Test 0.19) in SOC arm ( P  < 0.001 for ΔBalance Test difference); 92% of CERI participants adhered to the study for 12 weeks. No adverse events were reported by CERI participants.

CONCLUSION

CERI was safely administered at pilot randomized clinical trial, while all participants showed minimal improvement in gait speed, grip strength, 5 Sit-down Tests, and Balance Test. But multicenter, larger sample clinical trials are needed to track the effects of CERI.

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.

Assessment of gnostic and stereognostic functions in patients with liver cirrhosis: A comparative study with healthy controls

BACKGROUND

Individuals diagnosed with liver cirrhosis typically experience a variety of symptoms. Decompensation, a critical stage in the disease's progression, is characterized by the emergence of prominent clinical signs. These signs typically include ascites, bleeding tendencies, hepatic encephalopathy, and jaundice. Furthermore, it is noteworthy that regions in the sensorimotor cortex responsible for practical and gnostic functions are closely situated within the parieto-occipital part of the cortex. Liver cirrhosis may also have an impact on this aspect of human motor function.

OBJECTIVES

The main objective of the study is to compare the gnostic function and stereognostic function in individuals with liver cirrhosis and those in a healthy population.

METHODS

The patients included in our registry, known as RH7, were enrolled in our study. The first group consisted of 74 liver cirrhosis patients (including 25 women and 49 men). The control group consisted of a 63 healthy population (including 23 women and 40 and men). Both groups underwent both the Petrie and kinaesthesia tests.

RESULTS

The results of the Petrie test, which compared healthy participants with those with liver cirrhosis, indicate that the healthy population achieved a significant difference in both right and left upper limb compared to those with liver cirrhosis patients (p< 0.05). The healthy population showed a significant difference compared to liver cirrhosis patients in the kinesthesia test (p< 0.05), except for the second attempt with the left upper limb (p= 0.267). According to the LFI, there was no significant difference in either upper limb during both the initial and second attempts of Petrie test (p> 0.05).

CONCLUSION

Patients with liver cirrhosis exhibited significantly poorer gnostic functions compared to the healthy population. This condition also leads to notable impairments in motor functions, affecting both the precision and coordination of movements. Despite these deficits, frailty alone does not appear to be an indicator of worsened gnostic or stereognostic functions. Therefore, while liver cirrhosis has a clear negative impact on motor and cognitive abilities, the presence of frailty does not necessarily exacerbate these specific cognitive deficits. This distinction is crucial for clinical assessments and interventions targeting motor and cognitive rehabilitation in patients with liver cirrhosis.

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.
