BACKGROUND/AIMS: This study introduces methods for estimating the cost of liver disease and presents useful and reliable sources of data. The available evidence on the costs associated with liver disease is also discussed. METHODS: Costing methodology can be used to identify, measure, and value relevant resources incurred during the care of patients with liver diseases. It adjusts for discounting, skewed distribution, and missing or censored cost data. The human capital approach for productivity cost assumes that deceased patients would have lived to a normal expected life expectancy, and have earned a salary in line with the current age profile of wages, in order to measure potential earnings lost due to premature death or job loss. EVIDENCE: The number of deaths due to liver cancer (C22) increased from 6,384 in 1983 to 11,405 in 2013, while deaths due to other liver diseases (K70-K76) increased from 12,563 in 1983 to 13,458 in 1995, and then declined to 6,665 in 2013. According to the Global Burden of Disease study conducted by the World Health Organization, liver cancer caused 325,815 disability-adjusted life years (DALYs), and cirrhosis of the liver caused 206,917 DALYs in 2012. The total cost of liver disease was estimated at 1,941 billion Korean won in 2001 and 5,689 billion Korean won in 2008. Much of this cost is attributable to productivity cost, and especially that of economically active men. CONCLUSIONS: The economic burden of liver disease is immense because of the associated high mortality and morbidity, especially among the economically active population. This indicates the need to prioritize the development of appropriate health interventions.

BACKGROUND/AIMS: Chronic liver disease is closely associated with lifestyle, and public enlightenment of the lifestyle factors is important in reducing prevalence of chronic liver disease. The KASL (Korean Association for the Study of the Liver) conducted a survey of basic information and epidemiological data regarding chronic liver diseases. METHODS: A survey of chronic liver disease involving a total of 2,794 respondents was conducted. The respondents included patients and their guardians, visitors for health check-ups, and online pollees who completed a questionnaire on the awareness of fatty liver or chronic liver disease. RESULTS: Of the entire cohort, 854 (39.7%) said they have had or still have fatty liver or an elevated transaminase level (>40 IU/L), but only 23.4% of the respondents had visited a hospital. It was found that 35% of healthy subjects and 45% of patients and their guardians misunderstood hepatitis B as the hereditary disesase. Furthermore, 26% of the subjects responded that patients with inactive hepatitis B do not require regular follow-up. While 17.9% answered that it is not too late to test for liver cancer when symptoms arise, 38.8% believed that liver transplant in liver cancer patients has a low success rate and is thus not recommended. CONCLUSIONS: Despite the inundation of information and widespread media advertising, the awareness of chronic liver disease is unsatisfactory among Korean adults. Systematic nationwide studies are needed to obtain data and information regarding the prevalence of chronic liver disease and patterns of use of the health-care system.

The study of the epidemiology of toxic liver injury has been limited in Korea. The number of hospitalizations for toxic liver injury has been estimated to be 2,400 persons per year. About 30~40% of fulminant hepatitis was attributed to toxic hepatitis. The frequent causative agents of toxic hepatitis in Korea are herbal medicines (34~40%), folk remedies (23~34%), and prescribed medicines (24~55%). However, the most common agents causing severe liver injury including fulminant hepatitis are herbal medicine and folk remedies. Antituberculosis drugs and acetaminophen are two common causes of fulminant hepatitis among prescribed drugs. Alcohol is one of the leading causes of chronic liver disease in Korea. No nationwide study on the epidemiology of alcoholic liver disease (ALD) has been carried out, but 7~31% of cirrhosis has been reported to be alcoholic in a few single-center studies. Alcohol could be a risk factor for the development of hepatocellular carcinoma (HCC) in chronic viral hepatitis. Several studies have shown that alcohol increased the risk of HCC in liver cirrhosis with HBsAg or anti-HCV. Furthermore, alcoholic cirrhosis with occult hepatitis B virus infection increased the risk of HCC.

With the economic development and living standards improvement, various chronic viral liver diseases in children is decreasing year by year, and the liver diseases related to heredity, environment and living habits is increasing. Although liver disease in children is relatively rare and is not the main cause of childhood mortality, chronic liver disease cannot be ignored for its effect on children's growth and development, mental health, quality of life and the economic burden to family or society. Therefore, more attention should be paid to the early screening, diagnosis and treatment of pediatric liver diseases, in order to delay or prevent its progression efficiently.

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease seen in patients with obesity, diabetes, and metabolic syndrome. Metabolic syndrome is an important predictor of the severe form of NAFLD, nonalcoholic steatohepatitis (NASH), and NASH patients with diabetes have an increased risk of liver cirrhosis and hepatocellular carcinoma. With the prevalence of obesity and diabetes around the world, NAFLD has become a global public health problem. NAFLD is not only one of the most important causes of liver-related disability and mortality, but also associated with the increasing incidence of diabetes and cardiovascular disease. The effective prevention and treatment of NAFLD is expected to reduce the burden of liver disease and cardiovascular disease. Therefore, this article overviews the advances in the diagnosis, prevention, and treatment of NAFLD.

OBJECTIVETo study the epidemiological characteristics of liver diseases in a rural population in Southern Guangxi, China.

METHODSThe enzyme immunoassays was used to detect of HBsAg and AFP. AFP positive serum samples were further examined for concentration of AFP by using a radio immunoassays. Liver morphological changes were measured with ultrasonography of type B.

RESULTSThe positive rates of HBsAg in the studied population was 17.8% (2800/15,701). The prevalence rates of viral hepatitis B, cirrhosis, primary liver cancer, clonorchiasis, fatty liver disease, alcoholic liver disease were 1.1% (173/15,701), 0.4% (63/15,701), 299.3 per 100,000 (47/15,701), 6.6% (1036/15,701), 4.8% (754/15,701) and 0.3% (47/15,701), respectively. The positive rates of HBsAg and the prevalence rates of viral hepatitis B, cirrhosis, primary liver cancer, clonorchiasis, fatty liver disease in male were significantly higher as compared with those in female (5.98 < or = chi(2) < or = 394.78, P < 0.01). No difference was observed in the prevalence rates of liver cavernous hemangioma and hepatic cysts between male and female. The prevalence rates of intrahepatic bile duct stones was significantly higher in female than in male (chi(2) = 30.80, P < 0.01). The positive rates of HBsAg and the prevalence rates of viral hepatitis B and clonorchiasis were decreased with age. But the prevalence rates of cirrhosis, primary liver cancer, fatty liver disease, alcoholic liver disease, liver cavernous hemangioma, hepatic cysts and intrahepatic bile duct stones were increased with age.

CONCLUSIONThe rural areas in the southern Guangxi are high prevalence regions of liver illness, and the male resident are even at high risk.
