Efficacy and safety of intragastric balloon for obesity in Korea.

Background/aims: Intragastric balloon (IGB) is the only available endoscopic bariatric and metabolic therapy in Korea. End-ball (Endalis) has the longest history of clinical use among the IGBs available in Korea. However, little clinical data on this system have been reported.

Increased heat shock protein 70 expression attenuates pancreatic fibrosis induced by dibutyltin dichloride.

Objectives: Heat shock protein (HSP) 70 performs a chaperoning function and protects cells against injury. Although the effect of HSPs against acute inflammatory change has been proven, the relationship between HSP70 and chronic pancreatitis remains unclear. This study aimed to investigate the protective effect of increased HSP70 expression induced by thermal stress against pancreatic fibrosis in experimental chronic pancreatitis.

Virologic response is not durable after adefovir discontinuation in lamivudine-resistant chronic hepatitis B patients.

Background/aims: We investigated the durability of the biochemical and virologic responses after adefovir (ADV) discontinuation in lamivudine-resistant (LMV-R) chronic hepatitis B (CHB) patients, and the outcomes of ADV discontinuation compared to that of ADV maintenance.

Methods: The indication for ADV treatment cessation was an undetectable level of hepatitis B virus (HBV) DNA documented on two occasions at least 6 months apart. All patients received additional ADV for at least 12 months after the confirmation of undetectable HBV DNA (Cobas TaqMan PCR assay, <70 copies/mL).

Clinical significance of the detection of antinuclear antibodies in patients with acute hepatitis a.

Background/aims: The findings of several recent studies suggest that antinuclear antibodies (ANAs) are frequently detected in patients with acute hepatitis A (AHA). However, the clinical significance of a positive ANA test remains uncertain. This study was performed to evaluate the clinical significance of ANAs in AHA patients.

Recurrence rates and factors for recurrence after radiofrequency ablation combined with transarterial chemoembolization for hepatocellular carcinoma: a retrospective cohort study.

Purpose: There have been reports that radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) is as equally effective as surgical resection for the treatment of hepatocellular carcinoma (HCC). This study aimed to evaluate recurrence rate and risk factor of recurrence after RFA combined with TACE for early stage HCC.

Methods: We reviewed the medical records of the patients who were diagnosed with early stage HCC between March 2006 and August 2008 at Korea University Medical Center and treated with RFA combined with TACE for curative intent (n = 65).

Serum aminotransferase levels instead of etiology affects the accuracy of transient elastography in chronic viral hepatitis patients.

Background And Aim: It is still uncertain whether the accuracy of transient elastography (TE) in predicting the fibrosis stage is similar in chronic hepatitis B (CHB) and chronic hepatitis C (CHC). The present study was carried out to evaluate whether the underlying cause of chronic viral hepatitis affects the predictive accuracy of TE.

Methods: Patients with CHB or CHC who were admitted for a liver biopsy were enrolled.

Healthy range for serum ALT and the clinical significance of "unhealthy" normal ALT levels in the Korean population.

Background And Aims: It remains unclear whether the currently-used normal range for serum alanine aminotransferase (ALT) levels really reflects a healthy liver. The present study was conducted to evaluate the healthy range of serum ALT in the Korean adult population and to determine the clinical significance of unhealthy levels.

Methods: We reviewed the medical records, including questionnaires and the results of laboratory and radiological tests conducted at the Health Promotion Center at Korea University Anam Hospital between March 2005 and February 2007.

Liver cirrhosis induced by porphyria cutanea tarda: a case report and review.

Porphyria cutanea tarda (PCT) is a metabolic disorder that results in a decrease in uroporphyrinogen decarboxylase activity. It is characterized by photosensitivity, bullae formation, and skin pigmentation. There are four types of PCT: acquired, familial, toxic, and hepatoerythropoietic.

Terlipressin-induced hyponatremic seizure.

Terlipressin is a splanchnic constrictor that is used to control variceal bleeding and is considered to have a very good safety profile compared to vasopressin. However, side effects such as hyponatremia and seizure, although very rare, can occur. Recently, the authors have experienced a case of hyponatremia induced by infusion of terlipressin which resulted in generalized seizure.

Dynamic changes in liver stiffness during the course of acute hepatitis A.

Objective: Several recent studies have suggested that hepatic necroinflammation can alter the results of liver stiffness measurements (LSMs) obtained using the FibroScan device. However, the precise relationship between acute hepatic inflammation and LSMs remains unclear. The aim of this study was therefore to evaluate the dynamic changes in LSMs during the course of acute hepatic inflammation.

[A case of acute cholestatic hepatitis induced by Corydalis speciosa Max].

Herbs are widely used as treatments for various symptoms. However, several herbs have been reported to be inducers of liver injury. We report herein a case of hepatotoxicity induced by Corydalis speciosa Max.

Usefulness of non-invasive markers for predicting liver cirrhosis in patients with chronic hepatitis B.

Background And Aim: Recently, various non-invasive blood markers and indices have been studied to overcome the limitations of liver biopsy, such as its invasiveness and sampling errors. However, the majority of these studies have focused on patients with chronic hepatitis C. Accordingly, this study was performed to evaluate the significances of various non-invasive serum markers in terms of predicting the presence of liver cirrhosis in chronic hepatitis B.

Pancreatic tuberculosis masquerading as pancreatic serous cystadenoma.

Solitary pancreatic involvement of tuberculosis is rare, especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms. Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques. However, they are composed of a variety of neoplasms with a wide range of malignant potential, and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms.
