Despite the well-proven, safe and effective therapies for hepatitis B infection, delivery of treatment remains a significant challenge in resource-poor settings. Geopolitical and economic restrictions present additional difficulties in providing care in North Korea. However, treatment of patients with chronic hepatitis B remains a top priority for both the North Korean Ministry of Public Health and international agencies working in North Korean hepatitis healthcare facilities. Working in partnership, a path was created to institute this much-needed program. A consortium of United States and Australian humanitarian non-governmental organizations along with generous individual and corporate donors working in concert with local and national health authorities have succeeded in establishing the first hepatitis B treatment program in North Korea. The essential elements of this program include renovation of existing hepatitis hospitals, access to antiviral medications, establishment of laboratory facilities, creation of medical documentation and record-keeping, training of local health care professionals, and quarterly visits by international volunteer physicians and laboratory experts. Management and treatment decisions are made bilaterally. To date, nearly 1,500 patients have been evaluated, and over 800 have been started on long-term antiviral therapy. It is envisioned that this program will eventually be managed and funded by the Democratic People's Republic of Korea Ministry of Public Health. This program's success demonstrates a potential model for delivery of antiviral therapy for patients suffering from hepatitis B in other developing countries.

Objectives: Hepatitis A is a typical acute hepatitis caused by hepatovirus, and then most patients recover easily without progression to chronic condition. However, certain cases have the risk of severe symptoms or even death. This case report presented a hepatitis A accompanied with pancreatitis, which had been completely recovered in a Korean medicine hospital. Case presentation: A 38-year woman had felt the malaise, mild chilling, muscle pain and abdominal discomfort for 10 days, which led her visit doctors and took anti-pyretic analgesics and digestants. The symptoms, especially epigastric pain and fatigue, became worse, and then she hospitalized in a Korean medicine hospital. Based on the drastic elevations of hepatic enzymes (aspartate transaminase 1,604 IU/L and alanine transaminase 2,825IU/L) with an anti-HAV IgM positive, she was diagnosed with hepatitis A. After bed rest and herbal drug treatment (CGX and Innae-Tang) for 5 days, the laboratory abnormalities and subjective symptoms had been improved gradually, except the upper gastric discomfort and pain. Those symptoms had anticipated the comorbidity with HAV-induced pancreatitis, supported by the high level of serum lipase release. Another 5-day hospitalized treatment improved all subjective symptoms and then the laboratory results were completely normalized including detection of anti-HAV IgG within 15 days after discharge. Conclusion: This study presented a typical hepatitis A accompanied with pancreatitis, which should be considered in diagnosis and management of hepatitis A.

By radioimmunoassay, serologic markers of Hepatitis B Virus were studied in 44 patients with acute viral hepatitis, 10 patients with chronic persistent hepatitis, 10 patients with chronic active hepatitis, 44 patients with liver cirrhosis and 25 patients with primary hepato cellular carcinoma. The results were follows: 1) HBsAg was present in 77.2% of AVH, 40% of CPH, 80% of CAH, 55.1% of LC and 68 % of PHC. In this HBsAg positive groups, all but one in liver cirrhosis had Anti-HBc. 2) Anti-HBs was most commonly detected in CPR and accompanied by Anti-HBc except one case in AVH. 3) Anti-HBc was the only marker detected in 11.4% of AVH, 20% of CPH, 20% of CAH, 16.3% of LC and 8% of PHC. 4) HBeAg was most commonly found in HBsAg-positive CPH but Anti-HBe was most frequently detected in PHC. 5) The absence of HBV markers was noted in 2.3% of AVH, 10% of CPH, 8% of PHC except CAH and LC.

Background: Acute alcoholic intoxication patients (AAIP) are a common public health problem. The aim of this study was to perform a comprehensive laboratory analysis for these patients to investigate the co-morbid medical problem. Methods: We retrospectively reviewed laboratory findings of AAIP who were transferred to the emergency department (ED) from January 2017 to June 2017. Results: A total of 160 male patients were enrolled. Sixteen patients (16/160, 10.0%) and three patients (3/160, 1.9%) had macrocytic anemia and microcytic anemia, respectively. A total of 33 patients (33/160, 20.6%) showed thrombocytopenia ($<150{\times}10^9/L$). Twelve patients (12/159, 7.5%) showed low serum albumin level (<3.5 g/dL). Three patients (3/160, 1.9%) had chronic kidney disease stages 3-4 based on estimated glomerular filtration rate. Six patients (6/27, 22.2%) had high hemoglobin A1c (HbA1c) level (>7.0%). Positive rates of hepatitis B surface antigen and antiHBs antibody (anti-HBs Ab) were 3.5% (5/141) and 49.0% (68/141), respectively. Conclusion: Patients with AAIP who were transferred to ED had various laboratory abnormalities (anemia, thrombocytopenia, high HbA1c). They had low positive rate of anti-HBs Ab. This might be a public health problem, suggesting the need of hepatitis B virus vaccination program for AAIP. Our data suggest the need of further nationwide studies.

Hepatitis B viral infection which affect about 10% of Korean population manifests asymptomatic carrier, chronic hepatitis and liver cirrhosis and even associates with hepatocellular carcinoma. Clinical manifestations induced by hepatitis B virus vary depending on the degree of immune response by cytotoxic T cells against viral epitope-presenting liver cells. Since hepatitis B virus presents high rate of mutaton that might change the presented epitope and eventually alter immune response, viral mutations, especially in promoters and enhancers, have an important implication in hepatic inflammation and viral replication. To identify mutations related to the hepatic inflammation, we investigated sequence variations of hepatitis B viral promotor regions in the presence or absence of symptoms in hepatitis B carriers. For this, sera from persistently hepatitis B virus-infected mother-child pairs were collected. After PCR amplifiation of all hepatitis B viral promoters (C promoter, S1 promoter, S2/S promoter, X promoter) using serum DNA from each pair, viral promotors were sequenced by automatic sequencer and then sequence data were analyzed by ClustalW. In most cases, the dominant type of maternal virus was transmitted to the child. However, in some children, some new host specific viral variants could be observed in Cp, S1p and S2/Sp. The mutations in C promoter did not seem to be vertically transmitted but arose in new host independently after the wild type had been transmitted. Enhancer I containing X promoter revealed high host specific variations as has been reported before. Two S promoters, S1p and S2/Sp, have shown some point mutations in children, but no deletion mutations were detected as in chronic hepatitis patients in whom deletion mutations are frequently found. In conclusion, the children with the vertically transmitted hepatitis B virus mostly retain the dominant type virus that had been transmitted. However, host specific variants tended to accumulate over time, possibly as clinical symptoms develop.

Over 100 million people worldwide are chronic carriers of hepatitis C virus (HCV)(1). Chronic viral infections of the liver can prouess to cirrhosis, which may ultimately lead to hepatic failure or the development of hepatocellular carcinoma. There are a limited number of antiviral drugs on the market approved fur clinical management of chronic HCV infections; interferon-alpha (IFN$\alpha$) and the nucleoside analog ribavirin. However, whether used as monotherapy or in combination, adverse side-effects are associated with each drug and better therapeutic regimens are needed. (omitted)

Background : The prevalence of chronic hepatitis C virus (HCV) tends to be higher in the elderly. Pegylated interferon and ribavirin therapy (Peg-IFN/RBV) was recommended as the first-line treatment in the past decades, but this regimen showed unsatisfactory results in terms of safety and efficacy especially in elderly patients. Recently, it was demonstrated that dual therapy with daclatasvir and asunaprevir was well tolerated and led to high sustained virological response (SVR) rates, irrespective of age. We conducted a study to evaluate the efficacy and safety of daclatasvir plus asunaprevir by involving elderly patients aged above 65 years. Methods : We retrospectively analyzed clinical data from chronic hepatitis C virus (HCV) genotype 1b patients treated with daclatasvir plus asunaprevir from September 2015 to December 2016 at Seoul St. Mary's hospital. The patients were divided into two groups as elderly patients (older than 65 years) and non-elderly patients (younger than 65 years) and compared the efficacy and safety. Results : A total of 112 patients were treated with daclatasvir plus asunaprevir for chronic hepatitis C. Among them, 101 patients completed the whole treatment, and in 88 patients the amount of HCV RNA was measured after 12 weeks of treatment. There was no significant difference in SVR at 12 weeks between both the groups (p=0.68). Typically, 91.4%(32/35) of elderly patients and 94.3%(50/53) of non-elderly patients achieved SVR12. Common adverse events included elevation in transaminase level, headache, and gastrointestinal disorders. There was no statistical difference in the symptoms between the two groups. Conclusions : The combination therapy with daclatasvir plus asunaprevir exhibited similar rates of SVR12 in HCV elderly patients without leading to further adverse events compared to non-elderly patients. Therefore, it is proposed that daclatasvir plus asunaprevir therapy could be considered as an effective and safe treatment, even in patients aged over 65 years.

The age-specific anti-hepatitis A virus (HAV) seroprevalence rates in South Korea have changed markedly since the last 2030 years with an improvement in the socio-economic, housing, and environmental-sanitation conditions. These changes are characterized by very low anti-HAV seropositive rates among individuals less than 30 years of age; however, nowadays, most adolescents and young adults at an increased risk of developing symptomatic HAV infections. The Korea Center for Disease Control Sentinel Surveillance System has recently revealed an increase in the incidence of hepatitis A infection since 2001 and has revealed a potential endemic nature of the hepatitis A infection. Hepatitis A vaccines that were introduced in 1997 in Korea have made the current anti-HAV IgG positive rates in children (less than 10 years of age) approximately 50% of the rates observed in Seoul in 2006. However, in the same year, a few children were diagnosed as having anti-HAV IgG antibodies in Busan. This suggests the presence of some difference in the vaccination policy among doctors practicing in Seoul and Busan. Thus, the current recommendation of vaccinating 12-year-old child with HAV vaccination should be emphasized and a new strategy should be developed for the vaccination program to cater to the adolescents and young adults who are not immune, as well as for persons who are at a high risk for hepatitis A viral infection such as military personnel and hospital and day care center employees. Further, urgent hepatitis A vaccinations are also needed in patients with chronic liver diseases.

Viral hepatitis is the inflammation of liver cells caused by viruses, and still one of the major health-care problems worldwide. A number of viruses to cause hepatitis are type A, B, C, D, E or G. Among these viruses leading to hepatitis, B and C are more troublesome being more prone to chronic illness which can cause the potentially fatal conditions of hepatocellular carcinoma (HCC) and/or liver failure. If immediate treatment is not initiated, liver transplant is the only option left. Over the past few decades there has been remarkable progress in diagnose and monitor all hepatitis virus infections for treatment and prevention. Nonetheless, important challenges remain to develop more effective and safe vaccines for prevention as well as antiviral agents to reduce viremia/viral load by inhibiting viral replication. The development and evaluation of antiviral agents through carefully designed clinical trials over the last 25 years has heralded a new dawn in the treatment of patients chronically infected with the hepatitis B and C viruses, but not so for the D virus. The introduction of Direct Acting Antivirals (DDAs) for the treatment of HBV carriers has permitted the long term use of these compounds for the continuous suppression of viral replication. This review aims to summarize the current status and development approaches of antiviral drugs for the treatment of viral hepatitis and future perspectives.
