Overview
The most common cause of cirrhosis in the United States is chronic and heavy alcohol use, while the most common cause of cirrhosis worldwide is the hepatitis virus. Cirrhosis and chronic liver disease is the 12th leading cause of death in United States.
Epidemiology and Demographics
Prevalence
- In 2015, the prevalence of cirrhosis is approximately 270 per 100,000 individuals in the United States.
- Currently, approximately seventy percent of cirrhotic individuals are unaware of having liver disease and go undiagnosed.
- The prevalence of cirrhosis is higher in:
- Non-Hispanic blacks
- Individuals below the poverty line
- Mexican Americans
- Areas with high illiteracy rates
- Viral hepatitis (mainly hepatitis C) is responsible for more than half of the cases of cirrhosis in the United States.
- The cost of cirrhosis in terms of human suffering, hospital costs, and lost productivity is high.
- The rate of developing hepatocellular carcinoma in cirrhotic patients is approximately 1%-4% per year.[1]
- Alcoholic cirrhosis:
- Alcoholic cirrhosis develops in 15% of individuals who drink heavily for more than a decade.
- There is great variability in the amount of alcohol needed to cause cirrhosis (as little as 3-4 drinks a day in some men and 2-3 in some women).
- Chronic hepatitis B:
- Chronic hepatitis B is the most common cause of cirrhosis worldwide, especially South-East Asia, but is less common in the United States.
- Primary biliary cirrhosis:
- In some areas of the US and UK, the prevalence is as high as 1 in 4000.
- Non alcoholic fatty liver disease: [2][3][4]
- Alpha 1-antitrypsin deficiency:
- Approximately 40 percent of adults with homozygosity of PIZZ have histologically significant liver injury and cirrhosis.[5]
- Hepatopulmonary syndrome:
- Hepatopulmonary syndrome has a prevalence of 4-47% in cirrhotic patients.
- Portopulmonary hypertension:
- The prevalence of portopulmonary hypertension is 2% in patients with cirrhosis.
- Cirrhotic cardiomyopathy:
- The prevalence of cirrhotic cardiomyopathy is 50% in cirrhotic patients.
Case-fatality rate/Mortality rate
- The 10 year-mortality rate of cirrhosis is approximately 34- 66 percent, largely dependent on the cause of cirrhosis.
- In 2001, cirrhosis was the tenth leading cause of death amongst men and the twelfth leading cause of death amongst women in the United States.[6]
- In 2006, cirrhosis was the twelfth leading cause of all deaths in United States.[7]
Age
- Cirrhosis is infrequently seen in young adults.
- The incidence of cirrhosis increases with age; the median age at diagnosis of cirrhosis due to alcoholic liver disease is 52 years.
- The median age at diagnosis of cryptogenic/NAFLD/NASH cirrhosis is 60 years.
- The median age at diagnosis of autoimmune cirrhosis is 43 years.
Race
- The prevalence of cirrhosis is higher in: [3]
- Non-Hispanic blacks
- Individuals below the poverty line
- Mexican Americans
- Areas with high illiteracy rates
- Hispanics with hepatitis C infection
Gender
- The gender that is most commonly affected by cirrhosis varies, depending on the underlying etiology.
- Primary biliary cirrhosis:
- Primary biliary cirrhosis is more common in women.
- Chronic Hepatitis C:
- The risk of cirrhosis after 20 years is estimated to be approximately 10%-15% for men and 1-5% for women.[1]
- Non alcoholic fatty liver disease:
- Non-alcoholic fatty liver disease is more common among men than women in all age groups until age 60.
- At 60 years of age, the prevalence of cirrhosis in males and females equalizes, due to absence of the protective nature of estrogen.[8]
- Autoimmune hepatitis:
- Autoimmune hepatitis usually occurs in women in seventy percent of cases between the ages of 15 and 40.
- Alpha1 antitrypsin deficiency:
Developed Countries
- Viral hepatitis (mainly hepatitis C) is responsible for more than half of the cases of cirrhosis in the United States.
Developing Countries
- Chronic hepatitis B is the most common cause of cirrhosis worldwide, especially South-East Asia, but is less common in the United States.
