Resistance exercise in combination with aerobic exercise reduces the incidence of serious events in patients with liver cirrhosis: a meta-analysis of randomized controlled trials

BACKGROUND

Exercise, particularly resistance exercise, is beneficial for sarcopenia in patients with liver cirrhosis. However, the effects of exercise on events remain unclear. We aimed to examine the effects of exercise on serious events in patients with liver cirrhosis using a meta-analysis of randomized controlled trials (RCTs).

METHODS

A literature search was conducted in 2022. Eleven RCTs were selected for the meta-analysis (exercise group, n = 232; control group, n = 193). Serious events were defined as death or serious complications according to the original articles. A meta-analysis was performed using a random-effects model. The primary outcome was the incidence of serious events.

RESULTS

In the 11 RCTs, the incidence of serious events was 5.6% (13/232) and 12.3% (24/193) in the exercise and control groups, respectively. However, a meta-analysis demonstrated no significant difference in the incidence of serious events between the two groups (risk difference [RD] - 0.03, 95% confidence intervals (CI) - 0.07 to 0.02). In a stratification analysis based on a combination of aerobic and resistance exercise, five RCTs (n = 185) were enrolled. The incidence of serious events was 6.25% (7/112) and 24.7% (18/73) in the combination exercise and control groups, respectively. A meta-analysis demonstrated a significant reduction in the incidence of serious events in the combination exercise group compared with the control group (RD - 0.12; 95% CI - 0.21 to - 0.03).

CONCLUSIONS

Resistance exercise in combination with aerobic exercise reduces serious events in patients with liver cirrhosis. A combination of aerobic and resistance exercise may be beneficial to improve the prognosis of patients with liver cirrhosis.

A survey questionnaire evaluating physical activity patterns and determinants in patients with chronic liver disease

BACKGROUND

Physical activity can reduce the risk of morbidity and mortality in patients with chronic liver disease (CLD), whereas physical inactivity adversely affects clinical outcomes. Since data on physical activity in CLD are scarce, we conducted a questionnaire survey to assess the physical activity patterns and determinants in patients with CLD.

METHODS

We surveyed 437 patients from outpatient clinics at Gifu University Hospital about their physical activity patterns and determinants in 2022 using a validated questionnaire. The primary objective was to examine the proportion of patients who exercised and the clinical characteristics of patients who achieved high levels of physical activity. The secondary objectives were to explore the types, motivations, barriers, and preferences for physical activity.

RESULTS

Among the 397 eligible patients (median age 68 years; 51% men; and median Model for End-Stage Liver Disease score 6), 55.4% reported performing physical activity less than once a week. Physical activity frequency was not associated with sex, body mass index, comorbidities, or hepatic reserve. Among the respondents, 60.4% expressed concern regarding physical strength, and 80.6% expressed concern regarding physical inactivity. The main barriers to physical activity were work, household chores, and health problems. However, many respondents expressed their willingness to increase their physical activity frequency with some promotional policies. Walking was the most common physical activity practiced in the past year and the activity most respondents wanted to try in the future.

CONCLUSIONS

Patients with CLD are insufficiently active and need physical activity interventions, especially regarding walking.

Real-world efficacy of antibiotic prophylaxis for upper gastrointestinal bleeding in cirrhotic patients in Japan

BACKGROUND AND AIMS

Antibiotic prophylaxis is recommended for cirrhotic patients with upper gastrointestinal bleeding (UGIB). However, the frequency of bacterial infection in such patients has remarkably decreased over the decades, which has reduced the necessity for prophylaxis. Therefore, here we investigated the real-world adherence and effectiveness of antibiotic prophylaxis in cirrhotic patients with UGIB in Japan.

METHODS

This population-based study was conducted with a Japanese real-world database of the Health, Clinic, and Education Information Evaluation Institute. We enrolled cirrhotic patients who were hospitalized for UGIB between April 2010 and March 2020. After those who died within 24 h and who had aspiration pneumonia at admission were excluded, 1232 patients were analyzed. Rates of 6-week mortality, in-hospital bacterial infection, 30-day readmission, and length of hospital stay were evaluated.

RESULTS

Prophylactic antibiotics were prescribed in 142 (11.5%) patients. Multivariate analysis revealed that antibiotic prophylaxis was not significantly associated with either 6-week mortality or bacterial infection. After propensity score matching, the rates of 6-week mortality (7.2% vs. 8.4%, P = 0.810), bacterial infection (9.6% vs. 4.2%, P = 0.082), and 30-day unexpected readmission (7.2% vs. 7.8%, P = 1.000) were similar in patients with and without prophylaxis, whereas the median length of hospital stay was significantly longer in patients with prophylaxis (17 days vs. 13 days, P = 0.013).

CONCLUSIONS

Under current real-world circumstances in Japan, prophylactic antibiotics were prescribed in only 11.5% of cirrhotic patients with UGIB and were not associated with better clinical outcomes.

Branched chain amino acids in hepatic encephalopathy and sarcopenia in liver cirrhosis: Evidence and uncertainties

Liver cirrhosis is commonly associated with nutritional alterations, reported in 20% of patients with compensated disease and over 60% of patients with decompensated cirrhosis. Nutritional disturbances are associated with a worse prognosis and increased risk of complication. Serum levels of branched-chain amino acids (BCAAs) are decreased in patients with liver cirrhosis. The imbalance of amino acids levels has been suggested to be associated with the development of complications, such as hepatic encephalopathy and sarcopenia, and to affect the clinical presentation and prognosis of these patients. Several studies investigated the efficacy of BCAAs supplementation as a therapeutic option in liver cirrhosis, but uncertainties remain about the real efficacy, the best route of administration, and dosage.

Prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis

Background and Aim

Polypharmacy and sarcopenia are increasing public health problems worldwide. However, data on the prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis are limited.

Methods

Polypharmacy and sarcopenia were assessed in 239 patients with liver cirrhosis. Polypharmacy was defined as the daily use of six or more medications, and sarcopenia was diagnosed based on muscle strength and mass evaluated on computed tomography. The association between polypharmacy and sarcopenia and their effects on mortality were analyzed using logistic regression and Cox proportional hazards models.

Results

Among the 239 patients, 52% were men, the median age was 68 years, and the number of medications used per patient was 6. Further, 53% and 29% patients had polypharmacy and sarcopenia, respectively. The number of medications used and the prevalence of sarcopenia increased with age. Patients with polypharmacy and sarcopenia had similar characteristics, such as older age, increased medication use, advanced liver disease, and decreased muscle strength and mass. After adjusting for confounders, polypharmacy was significantly associated with sarcopenia (odds ratio, 2.11; 95% confidence interval [CI], 1.07-4.17). During the median follow-up of 2.2 years, 62 (26%) patients died. Polypharmacy (hazard ratio [HR], 1.83; 95% CI, 1.01-3.37) and sarcopenia (HR, 2.00; 95% CI, 1.12-3.50) independently predicted mortality. The prognostic significance of polypharmacy was more prominent in older adults than in younger adults (HR, 2.31; 95% CI, 1.01-5.67).

Conclusion

Polypharmacy and sarcopenia are interrelated and associated with poor prognosis in patients with cirrhosis. Further large, prospective, population-based studies are required to validate these findings.

Effects of Rifaximin on Circulating Albumin Structures and Serum Ammonia Levels in Patients with Liver Cirrhosis: A Preliminary Study

Circulating albumin structures, including their oxidized and reduced forms, are involved in hepatic encephalopathy (HE) development. However, the effects of rifaximin, a key drug in HE treatment, on the circulating albumin structure in patients with liver cirrhosis remain unclear. In this multicenter prospective study, eight patients with hyperammonemia (≥80 μg/dL) were enrolled. The circulating albumin structure was evaluated using the ratio of oxidized albumin (human nonmercaptalbumin, HNA). Patients were administered 400 mg rifaximin 3 times/day for 3 months, and laboratory data were assessed at baseline and during observation. Among the eight patients, three were men; the median age and body mass index were 70 years and 26.4 kg/m², respectively. The median HNA and serum ammonia levels at baseline were 41% and 143 μg/dL, respectively. After rifaximin therapy, HNA showed a decreasing tendency (median; from 41% to 36%, p = 0.321), but serum albumin levels showed no significant change (from 3.5 g/dL to 3.5 g/dL, p = 1.00); serum ammonia levels significantly reduced (median: 143 μg/dL to 76 μg/dL, p = 0.015). Thus, rifaximin reduces serum ammonia levels and may improve circulating albumin structure in patients with cirrhosis. Further large-scale studies are required to confirm these preliminary results.
