The most common finding related to nonalcoholic steatohepatitis is obesity, but a status of severe malnutrition can also induce the steatohepatitis. The authors report a rare case of steatohepatitis leading to hepatic decompensation caused by malnutrition after pancreaticoduodenectomy. A 68-year-old female patient who had been previously diagnosed with pancreatic cancer and had undergone pancreaticoduodenectomy 5 months previously presented with abdominal distension. Routine CT performed 3 months after the surgery revealed severe fatty liver without evidence of tumor recurrence. After undergoing pancreaticoduodenectomy her food intake had reduced, and as a result she had lost 7 kg of body weight over 2 months. At this admission, CT revealed moderate amounts of ascites without tumor recurrence. Furthermore, her albumin and lipid profile levels were markedly decreased, and she had a flapping tremor and slurred speech suggestive of hepatic encephalopathy. Her liver biopsy findings were consistent with steatohepatitis and disclosed macrovesicular steatosis without definite fibrosis. After careful nutritional control, her symptoms disappeared and her laboratory findings improved.

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.

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.

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) may be one of the important causes of cryptogenic hepatocellular carcinoma (HCC). The aim of this study was to evaluate whether patients with cryptogenic HCC share clinical features similar to that of NAFLD. METHODS: Cryptogenic HCC was defined as HCC that occurs in patients with the following conditions: HBsAg(-), anti-HCV(-), and alcohol ingestion of less than 20 g/day. All patients diagnosed with cryptogenic HCC from 2005 to 2012 (cryptogenic HCC group), and all patients diagnosed with HBV associated HCC between 2008 and 2012 (HBV-HCC group) were enrolled in the present study. Clinical features, BMI, lipid profiles, presence of diabetes mellitus, hypertension, and metabolic syndrome were compared between the two groups. RESULTS: Cryptogenic HCC group was composed of 35 patients (19 males and 16 females) with a mean age of 70+/-11 years. HBV-HCC group was composed of 406 patients (318 males and 88 females) with a mean age of 56+/-7 years. Patients in the cryptogenic HCC group were older (p=0.001) and female dominant (p=0.042) than those in the HBV-HCC group. There were no differences in the laboratory test results including lipid profiles and Child-Turcotte-Pugh class between the two groups. Patients in the cryptogenic HCC group had higher prevalence of diabetes (37% vs. 17%, p=0.015), hypertension (49% vs. 27%, p=0.051), metabolic syndrome (37% vs. 16%, p=0.001), and higher BMI (25.3 kg/m2 vs. 24.1 kg/m2, p=0.042) than those in the HBV-HCC group. The tumor stage was more advanced (stage III and IV) at diagnosis in the cryptogenic HCC group than in the HBV-HCC group (60% vs. 37%, p=0.007). CONCLUSIONS: Cryptogenic HCC has clinical features similar to that of NAFLD and is diagnosed at a more advanced tumor stage.

BACKGROUND/AIMS: Non-alcoholic fatty liver disease (NAFLD) is closely associated with abdominal obesity, dyslipidemia, hypertension, and Type 2 diabetes, which are all features of the metabolic syndrome. The aim of the present study was to elucidate whether NAFLD is associated with carotid atherosclerosis. METHODS: The study population comprised 659 subjects without hepatitis B and C infections and who did not consume alcohol. Fatty infiltrations of liver were detected by abdominal ultrasonography, and intima-media thickness (IMT) and plaque prevalence were estimated by carotid ultrasonography. RESULTS: The mean values of systolic and diastolic pressures, body mass index (BMI), aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, uric acid, total cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol, fasting glucose, fasting insulin, homeostasis model of assessment (HOMA) index, hemoglobin A1c, and plasminogen activator inhibitor-1 differed significantly between patients with NAFLD (n=314) and normal controls (n=345). The carotid IMT was 0.817+/-0.212 (mean+/-SD) mm in patients with NAFLD and 0.757+/-0.198 mm in normal controls (p<0.001). The prevalence of carotid plaques was higher in patients with NAFLD (26.4%) than in normal controls (15.9%) (p<0.001). This association persisted significantly after adjusting for age, sex, BMI, HOMA index and individual factors of metabolic syndrome by multiple logistic regression analysis. CONCLUSIONS: Patients with NAFLD are at a high risk of carotid atherosclerosis regardless of metabolic syndrome and classical cardiovascular risk factors. Therefore, the detection of NAFLD should alert to the existence of an increased cardiovascular risk. Moreover, NAFLD might be an independent risk factor for cardiovascular disease.
