Dengue fever is an acute febrile disease caused by the dengue virus, which belongs to the flaviviridae family, and this virus is transmitted by the bite of the mosquito Aedes aegypti. It occurs in the tropical climates of the South Pacific, Southeast Asia, India, Africa and the subtropical zone of America. Imported cases of Dengue fever and Dengue hemorrhagic fever are rapidly increasing as many Koreans are now traveling abroad. Liver injury is usually detected by laboratory investigation according to a surveillance protocol. Although liver injury by dengue virus has been described in Asia and the Pacific islands, the pathogenic mechanisms are not yet fully clarified. It is usually expressed in a self-limiting pattern and the patient has a complete recovery. We report here on a case of a young woman who presented with general weakness, nausea and significant elevation of the aminotransferase levels, and she was diagnosed with dengue fever.

Acute viral hepatitis in human can be caused by a large number of viruses with a wide range of clinical manifestations and laboratory findings. EBV is a rare causative agent of an acute hepatitis, during the course of infectious mononucleosis. Hepatic manifestations of EBV are usually mild and resolve without serious complications. EBV is rather uncommonly confirmed as an etiologic agent in acute viral hepatitis of adults and it rarely causes cholestatic hepatitis. We report a case of EBV hepatitis with cholestatic feature that was verified through serum viral marker and liver biopsy.

BACKGROUND/AIMS: Minimal hepatic encephalopthy in patients with clinically asymptomatic chronic progressive liver disease may have adverse effects on daily activity. We evaluated the differences in the cognitive function of patients with chronic hepatitis and liver cirrhosis group according to the Child-Pugh classification. METHODS: We enrolled 61 consecutive chronic liver disease patients. We used the following study instruments: visual continuous performance test, a spatial memory test, the Wisconsin card-sorting test chosen from Neuroscan and STIM system (Study of the Usefulness of Computerized Neuropsychological Test, Neurosoft company, New York, NY, USA), a global-local processing test and an electroencephalogram (EEG). RESULTS: A significant correlation was found between neurologic abnormalities and the degree of liver disease. The result of the neuropsychological test and the EEG showed that cognitive function decreased according to the severity of chronic liver disease, especially in liver cirrhosis. Cirrhotic patients, especially in Child-Pugh C group, exhibited selective deficits in complex attention and fine motor skills as well as visual spatial perception, with preservation of memory. CONCLUSIONS: The STIM and EEG are simple, subjective and reproducible methods and may be used as early detection methods of minimal hepatic encephalopthy.

BACKGROUND/AIMS: Liver biopsy is a standard method for diagnosis of liver cirrhosis in patients with chronic hepatitis. Because liver biopsy is an invasive method, non-invasive methods have been used for diagnosis of compensated liver cirrhosis in patients with chronic hepatitis. The current study was designed to evaluate the usefulness of ultrasonography and routine blood tests for diagnosis of compensated liver cirrhosis in patients with chronic viral hepatitis. METHODS: Two hundred three patients with chronic viral hepatitis who underwent liver biopsy were included in this study and ultrasonography and routine blood tests were analyzed retrospectively. Ultrasonographic findings, including surface nodularity, parenchyma echogenecity, and spleen size, were evaluated. The diagnostic accuracy of ultrasonography and routine blood tests were examined. RESULTS: Discriminant analysis with forward stepwise selection of variables showed that liver surface nodularity, platelet count, and albumin level were independently associated with compensated liver cirrhosis (p<0.05). Cross-tabulation revealed that the following 4 variables had >95% specificity: platelet count <100,000 /uL; albumin level <3.5 g/dL; INR >1.3; and surface nodularity. If at least one of the four variables exists in a patient with chronic viral hepatitis, we can predict liver cirrhosis with 90% specificity and 61% sensitivity. CONCLUSIONS: These results suggest that four variables (platelet count <100,000 /uL, albumin level <3.5 g/dL, INR >1.3, and surface nodularity) can be used for identification of liver cirrhosis in patients with chronic viral hepatitis with high specificity.

OBJECTIVETo study the nosocomial fungal infections in the patient with severe hepatitis and analyze of risk factor.

METHODSAll 115 severe hepatitis with fungal infections inpatients was studied prospectively.

RESULTSWe identified 115 cases with fungal infections, the mean age of patients was 37.2+/-21.5 years, male: 49 cases, female 66 cases. Infection of abdominal cavity accounted for 40.9%, infectious rate in respiratory tract and digestive tract were 26.9%, 21.8%, respectively. Candida albicans accounted for 67.6%. Use of broad-spectrum antibiotic and corticosteroids, neutropenia, severity of liver disease, improper medical manipulations as significant risk factors for fungal infection. Death rate of study group and control group was 59.1%, 34.8%, respectively (x2=36.0). In multivariate analysis, neutropenia, disseminated infection and severity of liver diseases were independent prognostic factors.

CONCLUSIONIdentification of risk factors and predictors of a poor outcome in patients with severe hepatitis with fungal infections, it suggested that implications in prophylaxis of fungal infection, early diagnosis and appropriate therapy would be important for these patients.

Cytomegaloviral hepatitis is an infantile liver disease commonly encountered in China, which could be differentiated into 4 patterns with different clinical conditions. Along with the progress of laboratory diagnostic techniques, multiple diagnostic approaches are available for this disease, but accurate diagnosis can only be made when individual patients' realities are taken into consideration. Clinical treatments are various, and the Western medicine used is mainly anti-viral agents such as Ganciclovir, and so far no unified therapeutic program has been formed. More and more ways of regarding Chinese medicine treatment of cytomegaloviral hepatitis have been published increasingly in recent years, though further research to seek preferable treatment programs is still expected.

BACKGROUND/AIMS: Liver stiffness (LS) measurement by transient elastography can estimate the degrees of liver fibrosis in patients with chronic liver disease. However, longitudinal data of LS after recovery of acute viral hepatitis are still lacking. In the present study, we aimed to evaluate among LS of patients at various stages of viral hepatitis and normal control. METHODS: Patients who had admitted at Korea University Ansan Hospital between January 2006 and January 2007 due to acute viral hepatitis and recovered were recruited (group A, n=22). We compared the liver biochmistry and LS of group A with those of healthy control group (group B, n=23), current acute viral hepatitis group (group C, n=49), and chronic viral hepatitis group (group D, n=66). RESULTS: Mean ALT, total bilirubin, and LS level of group A were not different from group B (p=0.318, p=0.116, p=0.125, respectively). However, group A had lower ALT, total bilirubin, and LS values compared to group C (all p<0.001), and lower ALT and LS values compared to group D (p=0.007, p<0.001). The mean total bilirubin was not significantly different from group D (p=0.117). CONCLUSIONS: Our data suggest that liver fibrosis is a long-term sequela of chronic hepatitis, and not developed in patients who recovered from acute viral hepatitis.
