BACKGROUND/AIMS: The aim of this study was to describe the types and causes of liver disease in patients from a single community hospital in Korea between April 2005 and May 2010. METHODS: A cohort of patients who visited the liver clinic of the hospital during the aforementioned time period were consecutively enrolled (n=6,307). Consistent diagnostic criteria for each liver disease were set by a single, experienced hepatologist, and the diagnosis of all of the enrolled patients was confirmed by retrospective review of their medical records. RESULTS: Among the 6,307 patients, 528 (8.4%) were classified as acute hepatitis, 3,957 (62.7%) as chronic hepatitis, 767 (12.2%) as liver cirrhosis, 509 (8.1%) as primary liver cancer, and 546 (8.7%) as a benign liver mass or other diseases. The etiologies in the acute hepatitis group in decreasing order of prevalence were hepatitis A (44.3%), toxic hepatitis (32.4%), other hepatitis viruses (13.8%), and cryptogenic hepatitis (9.1%). In the chronic hepatitis group, 51.2% of cases were attributed to viral hepatitis, 33.3% to nonalcoholic fatty liver disease, and 13.0% to alcoholic liver disease (ALD). Of the cirrhoses, 73.4% were attributable to viral causes and 18.1% to alcohol. Of the hepatocellular carcinoma cases, 86.6% were attributed to viral hepatitis and 11.6% to ALD. Among the benign tumors, hemangioma comprised 52.2% and cystic liver disease comprised 33.7%. CONCLUSIONS: Knowledge of the current status of the type and cause of liver disease in Korea may be valuable as a basis for evaluating changing trends in liver disease in that country.

OBJECTIVETo study the relationship between nonalcoholic fatty liver disease (NAFLD) and the development of cardiovascular disease (CVD) in children with obesity.

METHODSTwo hundred and thirty-one obese children and 24 non-obese children as control were enrolled. Body mass index (BMI), serum triglyceride, blood pressure, liver function, and carotid artery intima-media thickness (IMT) were examined. The obese children were classified into two subgroups according to the diagnosis criteria: group 1 without liver disorder (OCWLD group, n=75) and group 2 with NAFLD (NAFLD group, n=156). The incidences of hyperlipidemia and hypertension, carotid artery intima-media thickness (IMT) and biochemical indicators were compared in the three groups.

RESULTSThe NAFLD group showed significantly greater carotid IMT (0.066+/-0.021 cm) than the OCWLD (0.060+/-0.011 cm) and control groups (0.037+/-0.007 cm) (P<0.05). The OCWLD group had also thicker IMT than the control group (P<0.05). The incidences of hyperlipidemia and hypertension were 39.7% and 40.4%, respectively in the NAFLD group, which were significantly higher than those in the OCWLD (22.7% and 29.3% respectively)and control groups (4.2% and 12.6% respectively) (P<0.05). The liner stepwise regression analysis showed that the IMT was positively correlated with BMI, NAFLD and ALT (adjusted R2=0.316, P<0.01).

CONCLUSIONSNAFLD may be not only an early marker but also an early state of CVD in obese children. Early diagnosis and treatment of NAFLD is crucial for the prevention of the occurrence and development of CVD.

BACKGROUND/AIMS: The red-blood-cell distribution width (RDW) is a newly recognized risk marker in patients with cardiovascular disease, but its role in nonalcoholic fatty liver disease (NAFLD) has not been well defined. The aim of the present study was to determine the association between RDW values and the level of fibrosis in NAFLD according to BARD and FIB-4 scores. METHODS: This study included 24,547 subjects who had been diagnosed with NAFLD based on abdominal ultrasonography and questionnaires about alcohol consumption. The degree of liver fibrosis was determined according to BARD and FIB-4 scores. The association between RDW values and the degree of fibrosis in NAFLD was analyzed retrospectively. RESULTS: After adjusting for age, hemoglobin level, mean corpuscular volume, history of hypertension, history of diabetes, and high-sensitivity C-reactive protein, the RDW values were 12.61+/-0.41% (mean+/-SD), 12.70+/-0.70%, 12.77+/-0.62%, 12.87+/-0.82%, and 13.25+/-0.90% for those with BARD scores of 0, 1, 2, 3, and 4, respectively, and 12.71+/-0.72%, 12.79+/-0.66%, and 13.23+/-1.52% for those with FIB-4 scores of <1.30, 1.31-2.66, and > or =2.67, respectively (P<0.05). The prevalence of advanced fibrosis (BARD score of 24 and FIB-4 score of > or =1.3) increased with the RDW [BARD score: 51.1% in quartile 1 (Q1) vs. 63.6% in Q4; FIB-4 score: 6.9% in Q1 vs. 10.5% in Q4; P<0.001]. After adjustments, the odds ratio of having advanced fibrosis for those in Q4 compared to Q1 were 1.76 (95%CI=1.55-2.00, P<0.001) relative to BARD score and 1.69 (95%CI=1.52-1.98, P<0.001) relative to FIB-4 score. CONCLUSIONS: Elevated RDW is independently associated with advanced fibrosis in NAFLD.

OBJECTIVETo explore clinical and pathological features of chronic hepatitis B (CHB) with hepatic steatosis.

METHODSRetrospective analysis of hepatic steatosis in patients with liver biopsy-proven CHB between January 2005 and June 2008. Detailed clinical, laboratory and pathological data of CHB patients with steatosis were compared with those in sex-, age- matched CHB patients without steatosis. Patients co-infected hepatitis C virus or HIV or suffering from liver diseases of other causes were excluded.

RESULTSHistological hepatic steatosis was found in 33.4% of the 1263 CHB patients. The prevalence of steatosis was increased with time in the study period (20.3%, 28.2%, 32.6%, 65.4%, in trend analysis, P values less than 0.05). Body mass index, fasting plasma glucose, serum triglyceride and total cholesterol level in CHB patients with hepatic steatosis (n = 114) were significantly higher than those in 113 patients without steatosis (t values were 6.811, 2.733, 3.063, 2.340, respectively, P values less than 0.01 or 0.05). Compared to patients without steatosis, serum hepatitis B virus DNA titer in patients with steatosis was significantly lower (x2 = 6.154, P less than 0.05) and reduced sharply with the increased degree of hepatic steatosis (x2 = 4.941, P less than 0.05). There were no differences in liver biochemical test (t values were 0.744, 1.390, -0.029, -1.175, 1.393, respectively, P values more than 0.05), hepatic inflammation grade and fibrosis stage between CHB patients with and without steatosis (x2 = 1.434, 0.106, respectively, P more than 0.05), and these parameters were not associated with different degree of hepatic steatosis (x2 = 2.447, 2.911, respectively, P more than 0.05).

CONCLUSIONSHepatic steatosis is common in patients with CHB, and is related to metabolic disorders. Hepatic steatosis does not affect the severity of CHB. The reverse association of hepatitis B virus titer with the degree of hepatic steatosis needs further investigation.
