Main Causes and Prevalence of Cirrhosis
Cirrhosis, affecting over 2 million Americans, is commonly caused by non-alcoholic fatty liver disease (NAFLD) and alcohol-related liver disease (ALD). Although hepatitis C used to be a leading cause, increased screening and effective treatment have reduced its prevalence.
Diagnosing Cirrhosis
Physical examination findings like spider angiomas, palmar erythema, and dilated veins on the abdominal wall can indicate advanced cirrhosis, but these signs may not be sensitive. Additional blood-based and imaging-based tests are necessary to confirm cirrhosis, including the use of tests like the Fibrosis 4 index and elastography to assess liver fibrosis.
Managing and Treating Cirrhosis Complications
Controlling underlying liver diseases, such as NAFLD, viral hepatitis, and alcohol use disorder, can improve outcomes in patients with compensated cirrhosis. Regular screening for liver cancer using ultrasound and alpha-fetoprotein is recommended to facilitate early detection. Treating symptoms of cirrhosis includes using lactulose and rifaximin for hepatic encephalopathy, aldosterone antagonists and diuretics for ascites, and non-selective beta blockers like carvedilol for the prevention of variceal bleeding.
Cirrhosis affects approximately 2.2 million adults in the US, and the annual age-adjusted mortality of cirrhosis has increased from 2010 to 2021. JAMA Senior Editor Karen E. Lasser, MD, MPH, and Elliot B. Tapper, MD, from the University of Michigan, discuss the diagnostic workup and evidence-based therapies for cirrhosis. Related Content:
