Physical exercise for people with cirrhosis

Area of Science:

• Hepatology and Gastroenterology
• Exercise Physiology
• Clinical Trials Research

Background:

• Cirrhosis frequently leads to muscle mass loss and weakness, increasing patient morbidity and mortality.
• Physical exercise is a potential intervention to mitigate these complications in individuals with cirrhosis.

Purpose of the Study:

• To evaluate the efficacy and safety of physical exercise interventions compared to sham exercise or no intervention in patients with cirrhosis.
• To assess the impact of exercise on mortality, morbidity, quality of life, and physical fitness in cirrhosis patients.

Main Methods:

• A systematic review and meta-analysis of randomized clinical trials were conducted.
• Searches included major databases (Cochrane, MEDLINE, Embase) and trial registers up to February 2018.
• Data from six trials involving 173 participants with Child-Pugh stage A or B cirrhosis were analyzed.

Main Results:

• Physical exercise interventions (8-14 weeks) did not significantly affect mortality (RR 0.19, 95% CI 0.01 to 3.73) or serious adverse events (RR 0.61, 95% CI 0.19 to 1.94).
• No clear benefits were observed for health-related quality of life, peak exercise oxygen uptake, or Six-Minute Walk Test performance.
• While mid-thigh circumference showed no change, a significant increase in mid-arm circumference was noted with physical exercise.

Conclusions:

• Current evidence suggests no definitive beneficial or detrimental effects of physical exercise on key clinical outcomes in cirrhosis patients.
• Further high-quality randomized clinical trials are necessary to establish the role of exercise in managing cirrhosis complications.
