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.

OBJECTIVETo study the clinical characteristics of patients with alcoholic liver disease (ALD).

METHODSThe records of the 302 Hospital of People's Liberation Army (Beijing, China) were searched to identify patients diagnosed with liver disease for retrospective analysis of ALD. Measurement data was summarized as mean +/- standard deviation and intergroup comparisons were made using ANOVA; count data was assessed using the chi-square test.

RESULTSAmong the total 4132 ALD cases, 97.68% were male and 2.32% were female; ages ranged from 18 to 95 years-old,with the average age being 48.11+/-10.58 years and the range of 40 to 60 years-old being the most frequently represented.Considering all patients with liver disease from 2003 to 2012,ALD cases increased over time (from 2.00% in 2003 to 5.05% in 2012). The overall ALD cases were represented by alcoholic cirrhosis (70.35%), alcoholic hepatitis (19.26%), alcoholic fatty liver (6.29%), and alcoholic liver failure (4.09%). Among the ALD patients between 40 and 60 years of age, 73.81% had cirrhosis,compared to 50.42% of ALD patients less than 40 years-old (P less than 0.001). Comparison of ALD cases in 5-year increments showed increasing trends in rates of alcoholic cirrhosis and alcoholic hepatic failure;moreover, there was an increasing annual trend in the percentage of alcoholic liver failure cases among the total cases of liver failure in our hospital.

CONCLUSIONFrom 2003 to 2012,our hospital admissions increased for patients with alcoholic liver disease, and the patients were primarily in the age range of 40-60 years-old. In general, incidences of alcoholic liver failure and cirrhosis increased in recent years, and cirrhosis has been common among the elderly patients with ALD.

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.

Alcohol consumption has increased over the past 40 years in Korea concomitantly with the country's rapid socioeconomic development. As a result, alcohol-related deaths and mortality continue to increase in Korea. This review will summarize the recent epidemiology of alcoholic liver disease in Korea.

OBJECTIVETo describe the brief survey of alcohol intake and the incidence of alcohol liver disease in Zhejiang province.

METHODS18,237 requested persons aged over 18 years were selected by multi-stage stratified cluster sampling in Zhejiang province. Questionnaire about alcohol consumption, hepatic ultrasonic scan and detection of hepatic enzymes and markers of HBV and HCV were carried out. Daily alcohol intake more than 40g (including equal to 40g/d) was essential for the diagnosis of alcoholic liver disease.

RESULTSAmong the 18,237 persons (male 12,042, female 6195), the average daily alcohol intake was (17.7 +/- 27.2) g. The incidence of alcoholic liver disease in Zhejiang province was 4.34% (male 6.36%, female 0.36%) in the whole population. Four subtypes were separated as alcoholic cirrhosis, alcoholic fat liver, alcoholic hepatitis and mild alcoholic injury in liver with the corresponding incidence of 0.68%, 0.94%, 1.51% and 1.21% separately.

CONCLUSIONAlcoholic liver disease is found to be a common disease in Zhejiang province, indicating an urgent need for the public education on alcohol abuse and the treatment on related health problems

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.
