Background/Aims@#Many patients uses the internet to obtain information about their diseases. However, there is increasing concern regarding the quality of internet information. Thus, we aimed to systematically evaluate the quality of websites containing educational information about non-alcoholic fatty liver disease (NAFLD) in Korea. @*Methods@#Naver, Daum, and Google search engines were searched using the term “non-alcoholic fatty liver disease” in Korean. Two reviewers independently evaluated website quality using the quality evaluation instrument (QEI), which awarded websites scores for specific information on various aspects of NAFLD, as well as a five-point Likert scale (1–5), the DISCERN instrument, and a global quality scale (GQS). @*Results@#Forty-seven websites met the inclusion criteria. We found that the quality of the internet information about NAFLD is generally poor. The mean QEI score with standard deviation was 10.31 ± 5.09 (range, 4 to 22), with only 17% of websites scoring higher than 10 points. The median GQS of the websites was 2.0, with no website achieving a score of 4 or 5. The QEI score was highly associated with the GQS score (r = 0.74, p < 0.01). For each DISCERN question from question 1 to question 15, the mean score was less than 3. @*Conclusions@#Overall, the internet health information for patients regarding NAFLD is poor and in need of much improvement. There is a need for institutional support, qualitative regulation of internet information, and development of an accreditation system to provide patients with internet health information of appropriate quality.

Background/Aims@#Recent data indicate the presence of liver enzyme abnormalities in patients with coronavirus disease 2019 (COVID-19). We aimed to evaluate the clinical features and treatment outcomes of COVID-19 patients with abnormal liver enzymes. @*Methods@#We performed a retrospective, multicenter study of 874 COVID-19 patients admitted to five tertiary hospitals from February 20 to April 14, 2020. Data on clinical features, laboratory parameters, medications, and treatment outcomes were collected until April 30, 2020, and compared between patients with normal and abnormal aminotransferases. @*Results@#Abnormal aminotransferase levels were observed in 362 patients (41.1%), of which 94 out of 130 (72.3%) and 268 out of 744 (36.0%) belonged to the severe and non-severe COVID-19 categories, respectively. The odds ratios (95% confidence interval) for male patients, patients with a higher body mass index, patients with severe COVID-19 status, and patients with lower platelet counts were 1.500 (1.029 to 2.184, p=0.035), 1.097 (1.012 to 1.189, p=0.024), 2.377 (1.458 to 3.875, p=0.001), and 0.995 (0.993 to 0.998, p>0.001), respectively, indicating an independent association of these variables with elevated aminotransferase levels. Lopinavir/ ritonavir and antibiotic use increased the odds ratio of abnormal aminotransferase levels after admission (1.832 and 2.646, respectively, both p<0.05). The median time to release from quarantine was longer (22 days vs 26 days, p=0.001) and the mortality rate was higher (13.0% vs 2.9%, p<0.001) in patients with abnormal aminotransferase levels. @*Conclusions@#Abnormal aminotransferase levels are common in COVID-19 patients and are associated with poor clinical outcomes. Multivariate analysis of patients with normal aminotransferase levels on admission showed that the use of lopinavir/ritonavir and antibiotics was associated with abnormal aminotransferase levels; thus, careful monitoring is needed.

Background@#Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. @*Methods@#We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. @*Results@#A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. @*Conclusion@#In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.

Background/Aims@#Although coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, the implication of pre-existing liver disease on the outcome of COVID-19 remains unresolved. @*Methods@#A total of 1,005 patients who were admitted to five tertiary hospitals in South Korea with laboratory-confirmed COVID-19 were included in this study. Clinical outcomes in COVID-19 patients with coexisting liver disease as well as the predictors of disease severity and mortality of COVID-19 were assessed. @*Results@#Of the 47 patients (4.7%) who had liver-related comorbidities, 14 patients (1.4%) had liver cirrhosis. Liver cirrhosis was more common in COVID-19 patients with severe pneumonia than in those with non-severe pneumonia (4.5% vs. 0.9%, P=0.006). Compared to patients without liver cirrhosis, a higher proportion of patients with liver cirrhosis required oxygen therapy; were admitted to the intensive care unit; had septic shock, acute respiratory distress syndrome, or acute kidney injury; and died (P @*Conclusions@#This study suggests liver cirrhosis is a significant risk factor for COVID-19. Stronger personal protection and more intensive treatment for COVID-19 are recommended in these patients.

To date, there are limited data and little consensus on treatment strategies for huge hepatocellular carcinoma (HCC). Surgical resection provides significantly better survival than other modalities for single large HCC regardless of tumor stage. Recently, with technological advances in radiation therapy, stereotactic body radiation therapy (SBRT) is considered an alternative treatment option for HCC. Herein, we present a case of huge HCC that was successfully managed by SBRT. Transarterial embolization, previously performed in Russia, was incomplete. It was also not suitable for resection and transarterial chemoembolization. Although the rationale for radiotherapy in huge HCC was insufficient, SBRT was performed because no other treatment options were available. Additional radiofrequency ablation was performed for small HCC in a different segment, and radiological complete response (CR) was achieved. The CR was maintained over 4 years. Therefore, SBRT may be an alternative treatment option for large HCC that is not suitable for curative treatment.

BACKGROUND/AIMS@#Previous studies have reported a high rate of sustained virologic response (SVR) and a low rate of serious adverse events with the use of daclatasvir (DCV) and asunaprevir (ASV) combination therapy. We evaluated the efficacy and safety of DCV and ASV combination therapy for patients with chronic hepatitis C virus (HCV) genotype 1b infection in real world.@*METHODS@#We enrolled 278 patients (184 treatment-naïve patients) from five hospitals in Daegu and Gyeongsangbuk-do. We evaluated the rates of rapid virologic response (RVR), end-of-treatment response (ETR), and SVR at 12 weeks after completion of treatment (SVR12). Furthermore, we investigated the rate of adverse events and predictive factors of SVR12 failure.@*RESULTS@#The mean age of patients was 59.5 ± 10.6 years, and 140 patients (50.2%) were men. Seventy-seven patients had cirrhosis. Baseline information regarding nonstructural protein 5A (NS5A) sequences was available in 268 patients. Six patients presented with pretreatment NS5A resistance-associated variants. The RVR and the ETR rates were 96.6% (258/267) and 95.2% (223/232), respectively. The overall SVR12 rate was 91.6% (197/215). Adverse events occurred in 17 patients (7.9%). Six patients discontinued treatment because of liver enzyme elevation (n = 4) and severe nausea (n = 2). Among these, four achieved SVR12. Other adverse events observed were fatigue, headache, diarrhea, dizziness, loss of appetite, skin rash, and dyspnea. Univariate analysis did not show significant predictive factors of SVR12 failure.@*CONCLUSIONS@#DCV and ASV combination therapy showed high rates of RVR, ETR, and SVR12 in chronic HCV genotype 1b-infected patients in real world and was well tolerated without serious adverse events.

Radiofrequency ablation (RFA) is a minimally invasive local therapy for hepatocellular carcinoma (HCC). Even though RFA is considered to be a safe treatment modality, a variety of complications have been reported. Recently, we encountered a case of refractory fistula between a liver abscess and the gallbladder after RFA. A 64-year-old woman diagnosed with HCC associated with chronic hepatitis B was treated by RFA. After RFA, she experienced abdominal pain, and abdominal computed tomography (CT) revealed a liver abscess complicated by a previous treatment of HCC, she was treated with intravenous antibiotics and percutaneous abscess drainage. Follow-up abdominal CT revealed a fistula between the liver abscess and gallbladder, which was successfully treated with percutaneous transcatheter n-butyl-2-cyanoacrylate (NBCA) embolization. We herein report the rare case of a refractory fistula between a liver abscess and the gallbladder after RFA in a patient treated with NBCA embolization.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) has been widely accepted as a method of treatment of early gastric tumor. This study aimed to identify the incidence and characteristics of multiple gastric tumors after ESD. METHODS: Patients with early gastric tumors who were treated by ESD from January 2004 to June 2012 and followed up with endoscopic examination periodically for at least 1 year were enrolled. All multiple gastric lesions were subsequently treated with ESD and the medical records of the patients were retrospectively reviewed. RESULTS: In total, 643 patients were included. The mean duration of endoscopic follow-up was 45.27±27.59 (range, 12–148) months. Overall, 144 patients (22.4%) showed multiple gastric tumors during the follow-up period (44 synchronous [6.8%] and 100 metachronous [15.5%]). The cumulative incidence rate steadily increased during the follow-up period. More than 50% of the tumors that developed at the same longitudinal location of the stomach were of the same macroscopic and histological type as the primary lesions. CONCLUSIONS: Because synchronous and/or metachronous gastric tumors are common, considerable attention should be paid to detect multiple gastric lesions after ESD of early gastric neoplasm.

BACKGROUND/AIMS: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a common medical emergency that can be life threatening. This study evaluated predictive factors of 30-day mortality in patients with this condition. METHODS: A prospective observational study was conducted at a single hospital between April 2010 and November 2012, and 336 patients with symptoms and signs of gastrointestinal bleeding were consecutively enrolled. Clinical characteristics and endoscopic findings were reviewed to identify potential factors associated with 30-day mortality. RESULTS: Overall, 184 patients were included in the study (men, 79.3%; mean age, 59.81 years), and 16 patients died within 30 days (8.7%). Multivariate analyses revealed that comorbidity of diabetes mellitus (DM) or metastatic malignancy, age > or = 65 years, and hypotension (systolic pressure or = 65 years, and hemodynamic instability during hospitalization were predictors of 30-day mortality in patients with NVUGIB. These results will help guide the management of patients with this condition.

BACKGROUND/AIMS: Treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) remains controversial. We compared the outcomes of hepatic resection (HR), transarterial chemoembolization (TACE), and sorafenib therapy as treatments for HCC with PVTT. METHODS: Patients diagnosed as HCC with PVTT between January 2000 and December 2011 who received treatment with sorafenib, HR, or TACE were included. Patients with main PVTT, superior mesenteric vein tumor thrombosis, or Child-Turcotte-Pugh (CTP) class C were excluded. The records of 172 patients were analyzed retrospectively. HR, TACE, and sorafenib treatment were performed is 40, 80, and 52 patients respectively. PVTT was classified as either involving the segmental branch (type I) or extending to involve the right or left portal vein (type II). RESULTS: The median survival time was significantly longer in the HR group (19.9 months) than in the TACE and sorafenib groups (6.6 and 6.2 months, respectively; both p<0.001), and did not differ significantly between the latter two groups (p=0.698). Among patients with CTP class A, type I PVTT or unilobar-involved HCC, the median survival time was longer in the HR group than in the TACE and sorafenib groups (p=0.006). In univariate analyses, the initial treatment method, tumor size, PVTT type, involved lobe, CTP class, and presence of cirrhosis or ascites were correlated with overall survival. The significant prognostic factors for overall survival in Cox proportional-hazards regression analysis were initial treatment method (HR vs. TACE: hazard ratio=1.750, p=0.036; HR vs. sorafenib: hazard ratio=2.262, p=0.006), involved lobe (hazard ratio=1.705, p=0.008), PVTT type (hazard ratio=1.617, p=0.013), and CTP class (hazard ratio=1.712, p=0.012). CONCLUSIONS: Compared with TACE or sorafenib, HR may prolong the survival of patients with HCC in cases of CTP class A, type I PVTT or unilobar-involved HCC.

Hepatic tuberculosis (TB) is usually associated with pulmonary or miliary TB, but primary hepatic TB is rare less than 1% of all cases of TB. Because hepatic TB lacks typical clinical manifestations as well as typical imaging findings, it is difficult to differentiate TB from the malignancies such as hepatic metastasis, intrahepatic cholangiocarcinoma and hepatocellular carcinoma. A 76-year-old woman was presented with single liver mass detected on routine examination. She was clinically diagnosed with hepatocellular carcinoma and underwent surgical excision of the lesion. However, histologic examination revealed caseous necrotizing granuloma and the PCR test for Myco-bacterium tuberculosis was positive. The final diagnosis was primary hepatic TB. Here we report the case with primary hepatic TB who was initially misdiagnosed with hepatocellular carcinoma and underwent surgical excision.

Hepatocellular carcinoma (HCC) have relatively well known causative factors such as chronic hepatitis B, chronic hepatitis C, alcoholic liver disease, Non-alcoholic fatty liver disease (NAFLD), liver cirrhosis and so on. Recently, interesting reports that HCC in the absence of cirrhosis or other chronic liver disease and HCC associated with NAFLD and metabolic syndrome are increasing in USA. So far, there is no report about these issues in Korea. We present a 65 year-old obesity male who had no preceding chronic liver disease history. He was diagnosed as primary HCC and the mass was removed completely. However, HCC recurred shortly after operation. Multiple recurred HCC were treated with transcatheter arterial chemoembolization.

BACKGROUND/AIMS: Hepatic angiosarcoma, a rare and aggressive liver malignancy, is difficult to diagnose because of a lack of specific clinical features. The clinical and radiological features of patients with histologically confirmed hepatic angiosarcoma were examined. METHODS: Among 2,336 patients diagnosed with primary hepatic carcinoma at Keimyung University Dongsan Medical Center (Daegu, Korea) between May 2002 and February 2012, eight (0.03%) with histologically confirmed primary hepatic angiosarcoma were included. The patterns of disease diagnosis, tumor characteristics, treatment responses, and prognoses were reviewed retrospectively. RESULTS: Median age was 66 years-old (range, 41-80 years). Four patients were male. Five patients were compulsive drinkers. All patients had no HBsAg and anti-HCV. Initial radiologic diagnoses revealed primary hepatic angiosarcoma (n=2), hepatocellular carcinoma (n=2), hemangioma (n=2), and hepatic metastatic carcinoma (n=2). Definitive diagnoses were made by percutaneous needle biopsies in seven patients and surgical resection in one patient. At the time of the initial diagnosis, extrahepatic metastases were detected in three patients (37.5%). Metastatic sites included the spleen and lung, pericardium, and bone, in one patient each. Two patients underwent conservative treatments. The remaining patients underwent surgical resection (n=1), transcatheter arterial chemoembolization (n=1), and systemic chemotherapy (n=4). The median survival period was 214 days (range, 21-431 days). CONCLUSIONS: Hepatic angiosarcoma is a highly progressive disease with a poor prognosis. Detailed studies including histological examinations are essential to facilitate early diagnosis of the disease.

Gastric variceal bleeding has relatively low incidence rate compared to esophageal variceal bleeding. However, gastric variceal bleeding tends to lead to a massive bleeding and rebleeding which in turn leads to high mortality rate. In cases where endoscopic approach is limited, Ballon-occluded retrograde transvenous obliteration (BRTO) could be considered as a next modality of seizing acute bleeding. Venous catheterization should be preceded to perform venous embolization, however, in cases of hypovolemic shock status, alternative approaches are required. We are reporting a case of 60-year old female with hypovolemic status due to a massive hematemesis, who went through a percutaneous transhepatic glue embolization to control gastric variceal bleeding.

BACKGROUND/AIMS: Azathioprine (AZA) has been widely used in the therapy of inflammatory bowel disease (IBD) and autoimmune hepatitis (AIH). However, studies evaluating the adverse effects of AZA in these two diseases are lacking. The aim of this study was to compare the adverse effects of AZA in Korean IBD and AIH patients. METHODS: Patients with IBD or AIH who were treated with AZA at Keimyung University Dongsan Medical Center (Daegu, Korea) between January 2002 and March 2011 were enrolled. Their medical records were reviewed retrospectively in terms of clinical characteristics and adverse effects of AZA. RESULTS: A total of 139 IBD patients and 55 AIH patients were finally enrolled. Thirty IBD patients (21.6%) and eight AIH patients (14.5%) experienced adverse effects of AZA. In particular, the prevalence of leukopenia was significantly higher in the IBD group than in the AIH group (p=0.026). T474C mutation was observed in three of 10 patients who were assessed for thiopurine methyltransferase (TPMT) genotype. CONCLUSIONS: IBD patients are at increased risk for the adverse effects of AZA compared with AIH patients, of which leukopenia was the most commonly observed. Therefore, IBD patients receiving AZA therapy should be carefully monitored.

Only a few studies have evaluated the population-adjusted prevalence of gallbladder polyps (GBP). This study aimed to evaluate the changes in GBP prevalence and risk factors at a single health screening center in Korea from 2002 to 2012. Of 48,591 adults who underwent health screening between 2002 and 2012, 14,250 age- and gender-matched subjects were randomly selected to evaluate prevalence. Risk factors were analyzed between the GBP-positive and GBP-negative groups during 2002-2004 (Period A) and 2010-2012 (Period B). The annual prevalence of GBP over the 11-yr period was 5.4%. Annual prevalence increased from 3.8% in Period A to 7.1% in Period B. Male gender and obesity were independent risk factors for GBP in both periods. Hepatitis B virus surface antigen (HBsAg) positivity was a risk factor for GBP in Period A but not in Period B. The risk factors for GBP changed from HBsAg positivity to lipid profile abnormalities. Other variables including age, hypertension, diabetes, impaired fasting glucose, chronic hepatitis C virus infection, and liver function tests did not correlate with GBP. In conclusion, GBP prevalence is increasing and risk factors for GBP have changed in Korea. More attention should be paid to this issue in the future.

BACKGROUND/AIMS: Given the characteristic procedures involved in the endoscopy unit, the spread of pathogens is much more frequent in this unit than in other environments. However, there is a lack of data elucidating the existence of pathogens in the endoscopy unit. The aim of this study was to detect the presence of possible pathogens in the endoscopy unit. METHODS: We performed environmental culture using samples from the endoscopy rooms of 2 tertiary hospitals. We used sterile cotton-tipped swabs moistened with sterile saline to swab the surfaces of 197 samples. Then, we cultured the swab in blood agar plate. Samples from the colonoscopy room were placed in thioglycollate broth to detect the presence of anaerobes. After 2 weeks of culture period, we counted the colony numbers. RESULTS: The most commonly contaminated spots were the doctor's keyboard, nurse's cart, and nurse's mouse. The common organisms found were non-pathogenic bacterial microorganisms Staphylococcus, Micrococcus, and Streptococcus spp.. No definite anaerobe organism was detected in the colonoscopy room. CONCLUSIONS: Although the organisms detected in the endoscopy unit were mainly non-pathogenic organisms, they might cause opportunistic infections in immunocompromised patients. Therefore, the environment of the endoscopy room should be managed appropriately; moreover, individual hand hygiene is important for preventing possible hospital-acquired infections.

BACKGROUND/AIMS: Adefovir dipivoxil (ADV) is a nucleotide analogue that is effective against lamivudine-resistant hepatitis B virus (HBV). The aim of this study was to determine the long-term clinical outcomes after ADV rescue therapy in decompensated patients infected with lamivudine-resistant HBV. METHODS: In total, 128 patients with a decompensated state and lamivudine-resistant HBV were treated with ADV at a dosage of 10 mg/day for a median of 33 months in this multicenter cohort study. RESULTS: Following ADV treatment, 86 (72.3%) of 119 patients experienced a decrease in Child-Pugh score of at least 2 points, and the overall end-stage liver disease score decreased from 16+/-5 to 14+/-10 (mean +/- SD, P or =2 points; P=0.001) and high mortality following ADV rescue therapy (P=0.012). CONCLUSIONS: Three years of ADV treatment was effective and safe in decompensated patients with lamivudine-resistant HBV.
