Prevalence and Risk Factors of Sarcopenia in Patients with Cirrhosis: an Observational Study.

Objective:To identify the prevalence and predictors of sarcopenia in cirrhotic patients.METHODS:This observational, cross-sectional study was conducted at the National Institute of Liver and Gastrointestinal Diseases, Karachi, from January 30 to July 31, 2021, and comprised cirrhotic patients of either gender between aged 18-60 years. Clinical and laboratory data was recorded for each patient. Body weight was adjusted for ascites. Sarcopenia was determined based on the Asian Working Group for Sarcopenia-2019 guideline via hand grip strength and chair standing. Independent predictors for sarcopenia were identified. Data was analysed using SPSS 26.RESULTS:Out of 434 cirrhotic patients assessed, 386(89%) were enrolled. Of them, 237(61.4%) were males, 149(38.6%) were females, 327(84.7%) were aged >45 years and 201(52.1%) had moderate professional activity. Sarcopenia was detected in 314(81.3%) patients; 185(59%) males and 129(41%) females. Age, chair exercise and hand grip scores as well as haemoglobin, albumin and potassium levels were significantly associated with sarcopenia (p<0.05).Conclusion:Sarcopenia was found to be very common in patients with cirrhosis. Increasing age, concomitant comorbidities, and presence of liver decompensation increased the risk of sarcopenia.
