The global burden of chronic liver disease (CLD) is substantial. Due to the limited indication of and accessibility to antiviral therapy in viral hepatitis and lack of effective pharmacological treatment in nonalcoholic fatty liver disease, the beneficial effects of antidiabetics and non–antidiabetics in clinical practice have been continuously investigated in patients with CLD. In this narrative review, we focused on non-antidiabetic drugs, including ursodeoxycholic acid, silymarin, dimethyl4,4’-dimethoxy-5,6,5’,6’-dimethylenedixoybiphenyl-2,2’-dicarboxylate, L-ornithine L-aspartate, branched chain amino acids, statin, probiotics, vitamin E, and aspirin, and summarized their beneficial effects in CLD. Based on the antioxidant, anti-inflammatory properties, and regulatory functions in glucose or lipid metabolism, several non–antidiabetic drugs have shown beneficial effects in improving liver histology, aminotransferase level, and metabolic parameters and reducing risks of hepatocellular carcinoma and mortality, without significant safety concerns, in patients with CLD. Although the effect as the centerpiece management in patients with CLD is not robust, the use of these non-antidiabetic drugs might be potentially beneficial as an adjuvant or combined treatment strategy.

Viral hepatitis

Current status and strategies for hepatitis B control in Korea
Eun Ju Cho, Sung Eun Kim, Ki Tae Suk, Jihyun An, Soung Won Jeong, Woo Jin Chung, Yoon Jun Kim
Clin Mol Hepatol 2017;23(3):205-211.

Hepatitis B virus (HBV) infection is the most common cause of chronic liver diseases in Korea. After the introduction of the universal HBV vaccination program, the prevalence of hepatitis B surface antigen was markedly reduced, and Korea is now classified as an area of intermediate endemicity for HBV. However, there are still hurdles for elimination of hepatitis B, such as immunoprophylaxis failure against vertical transmission, occurrence of acute hepatitis B among peoples who did not have vaccination at younger age, and rapid increase of immigrant populations from HBV endemic areas. To achieve the World Health Organization goal of viral hepatitis elimination by 2030 in Korea, we suggest comprehensive policies for more effective control of hepatitis B as following: i) insurance coverage for antiviral prophylaxis in mothers with high viremia, ii) screening for hepatitis B seromarkers and catch-up HBV vaccinations of susceptible persons with hepatitis B, iii) establishment of an independent 'viral hepatitis sector' in Centers for Disease Control & Prevention to organize and execute comprehensive strategy for management of viral hepatitis, iv) encourage of management of HBV infection in immigrant populations, v) national campaign to promote awareness of hepatitis B.

Clin Mol Hepatol 2017;23(3):189-195.

Viral hepatitis is one of major global health challenges with increasing disease burden worldwide. Hepatitis B virus and hepatitis C virus infections are major causes of chronic liver diseases. They can lead to cirrhosis, hepatocellular carcinoma, and death in significant portion of affected people. Transmission of hepatitis B virus can be blocked by vaccination. Progression of hepatitis B virus-related liver diseases can be prevented by long-term viral suppression with effective drugs. Although vaccine for hepatitis C virus is currently unavailable, hepatitis C virus infection can be eradicated by oral direct antiviral agents. To eliminate viral hepatitis, World Health Organization (WHO) has urged countries to develop national goals and targets through reducing 90% of new infections and providing universal access to key treatment services up to 80%. This can lead to 65% reduction of viral hepatitis-related mortality. Here, we discuss some key features of viral hepatitis, strategies to control viral hepatitis suggested by WHO, and current status and strategies for viral hepatitis control in South Korea. To achieve the goal of viral hepatitis elimination by 2030 in South Korea, an independent 'viral hepatitis sector' in Centers for Disease Control & Prevention (CDC) needs to be established to organize and execute comprehensive strategy for the management of viral hepatitis in South Korea.

Viral hepatitis

Management of viral hepatitis in liver transplant recipients
Soung Won Jeong, YoungRok Choi, Jin-Wook Kim
Clin Mol Hepatol 2014;20(4):338-344.
Published online December 24, 2014
DOI: https://doi.org/10.3350/cmh.2014.20.4.338

Recurrence of viral hepatitis after liver transplantation (LT) can progress to graft failure and lead to a decrease in long-term survival. Recently, there have been remarkable improvement in the treatment of chronic hepatitis B (CHB) using potent antiviral agents. Combination of hepatitis B immunoglobulin and potent antiviral therapy has brought marked advances in the management of CHB for liver transplant recipients. Post-transplant antiviral therapy for hepatitis C virus infection is generally reserved for patients showing progressive disease. Acheiving a sustained virological response in patients with LT greatly ameliorates graft and overall survival, however this only occurs in 30% of transplant recipient using pegylated interferon and ribavirin (RBV). Direct acting antivirals such as protease inhibitors, polymerase or other non-structural proteins inhibitors are anticipated to establish the new standard of care for transplant recipients. In liver transplant recipients, hepatitis E virus infection is an uncommon disease. However, it can lead to chronic hepatitis and cirrhosis and may require retransplantation. Recently, 3-month course of RBV monotherapy has been reported as an effective treatment. This review focuses on the recent management and therapeutic approaches of viral hepatitis in liver transplant recipient.

Socioeconomic costs of liver disease in Korea
Sunmi Lee, Woojin Chung, Kyung-Rae Hyun
Korean J Hepatol 2011;17(4):274-291.
Published online December 26, 2011
DOI: https://doi.org/10.3350/kjhep.2011.17.4.274
Background/Aims

This study analyzed the scale and trends of the social and economic costs of liver disease in Korea for the past 5 years.

Methods

The social aspects of socioeconomic costs were projected for viral hepatitis (B15-B19), liver cirrhosis, malignant neoplasm of the liver (C22) and other liver diseases (K70-K76), as representative diseases by dividing costs into direct and indirect from 2004 to 2008. Direct costs include hospitalization, outpatient, and pharmacy costs in the health-care sector, and transportation and caregiver costs. Indirect costs include the future income loss due to premature death and the loss of productivity resulting from absence from work.

Results

The social and economic costs of liver disease were projected to be KRW 5,858 billion in 2004, KRW 5,572 billion in 2005, KRW 8,104 billion in 2006, KRW 6,095 billion in 2007, and KRW 5,689 billion in 2008. The future income loss resulting from premature death is thus greatest, from 73.9% to 86.1%, followed by the direct medical costs, from 9.0% to 18.1%. The productivity loss resulting from absence from work accounts for 3.3-5.5%, followed by the direct nonmedical costs such as transportation and caregiver costs, at 1.5-2.5%.

Conclusions

Among the socioeconomic costs of liver disease in Korea, the future income loss resulting from premature death is showing a decreasing trend, whereas direct medical costs are increasing dramatically.

Published online December 31, 2009
DOI: https://doi.org/10.3350/kjhep.2009.15.4.464
Background/Aims
Transient elastography is a new noninvasive tool for measuring liver stiffness that accurately predicts significant fibrosis and cirrhosis. However, several studies have indicated that liver stiffness can be significantly influenced by major changes in aminotransferase in patients with chronic viral hepatitis. The aim of this study was to determine the factors influencing liver stiffness in patients with chronic liver disease. Methods: We studied 158 patients with chronic liver disease who underwent transient elastography and liver biopsy sampling. Histologic findings on fibrosis and necroinflammatory activity in the biopsy specimens were evaluated according to the Korean Society of Pathologists Scoring System. Routine biochemical tests were performed according to standard methods. Results: Liver stiffness was strongly correlated with liver fibrosis stage (Spearman coefficient=0.636, P<0.001), lobular activity (Spearman coefficient=0.359, P<0.001), and portoperiportal activity grade (Spearman coefficient=0.448, P<0.001). Liver stiffness was significantly associated with serum levels of total bilirubin (P=0.025), direct bilirubin (P=0.049), gamma-glutamyl transpeptidase (P=0.014), platelet count (P=0.004), albumin (P<0.001), and international normalized ratio (P<0.001). Multivariate analysis showed that fibrosis stage (B 3.50, P=0.009) and lobular activity grade (B 3.25, P=0.047) were independently associated with liver stiffness. Conclusions: Liver stiffness as measured by transient elastography is associated with the grade of necroinflammatory activity and the stage of fibrosis, irrespective of serum ALT levels.

Korean J Hepatol 1996;2(1):47-53.
Background/Aims
As one of biological modifiers of immune reaction, thymomodulin is known to be peptide derivatives of thyrnic acid. Lysate, and thymomodulin can stimulate antibody formations by increasmg the functions of B and T tymphocytes. Furthermore, GM-CSF and TNF can be released by thymomodulin resulting in relief from bone marrow suppression. And these actions of thymomodulin affer a new therapeutic modality in chronic diseases ot the liver as well as chronic hronchitis. Although interferons are frequently under trials for chronic viral hepatitis B. anothersome of side etTec ts and cost effectiveness is often refractory to be used. Herein, this study was intended to estimate the effectiveness and side effects of per oral thymomodulin. Methods:Forty one patients with chronic viral hepatitis showing positivity of HBsAg over 6 months were treated with per oral !hymomodulin (15mlAmg/ml, h vice daily, over 6 months ), Clinical data of preand post-trial states were prospectively investigated, Results as a result, negative conversion of HBV DNA izvealed 20.6% out ol 34 patients showed HBsAg positivity. HBeAg was isappeared in 10.4 % among the 29 cases. Only two cases were shown the clearance of HBsAg. However. These data are statistically insignificant in comparison to the control group (p>0.05, chi-square test). The desirable effects were noticed as disappearance of acne in 5 cases, and amelioration of menstrual abnormalities in 3 cases. Undesirable side effects were only mild nausea in 3 cases, and indigestion in 2 cases. Conclusions:On thc basis of these data, it is suggested that oral thymomodulin is an easy and safe therapeutic approach in chronic viral hepatitis B but remains to be heralded by long-term clinical trials.

Korean J Hepatol 2000;6(3):301-310.
Background/Aims
This study was conducted to determine the effect of novel long-term maintenance treatment with lamivudine by gradual lengthening of the medication interval in patients with chronic active viral hepatitis B. Method: All patients were non-responder, relapsed or intolerable patients to previous interferon therapy. Patients were divided into a drug-interval changing study and a daily continual medication control group. Drug-interval changing protocol with gradual lengthening of the medication interval after conversion to undetectable HBV-DNA in serum and reduction of serum aminotransferase to normal level was monitored monthly. Results: Before treatment, 15 patients of the drug-interval change group and 11 patients of the daily medication group were similar in laboratory and pathologic findings. Mean follow-up periods were 12.8 moths and 11.4 months respectively. HBeAg seroconversion rate was higher in patients in the daily medication group (86.7% vs. 40.0%, p<0.05). The odds of loss of HBeAg, development of anti-HBe, and suppression of HBV-DNA are about 11 times, 7 times, and 8 times higher in the drug-interval change group compared with the daily medication group, respectively (p<0.05). Conclusion: Drug-interval lengthening method was effective in long-term suppression of viral replication with low cost.

Sang Woo Lee,Seung Won Seo,Heyng Woong Yang,Jae Kyu Seong,Seung Min Lee,Byung Seok Lee,Nam Jae Kim,Heon Young Lee
Korean J Hepatol 2000;6(3):350-359.
Background
/Aim: It is not easy to differentiate Salmonella from acute viral hepatitis (AVH), especially in the case of jaundice. Therefore we analyzed the differences between Salmonella hepatitis and AVH- B.
Method
Our study was performed retrospectively on 11 patients with acute hepatitis who had positive blood culture for Salmonella typhi and 11 patients with AVH- B as controls. Result: The greater proportion of patients with Salmonella experienced fever, headache, diarrhea, relative bradycardia and hepatomegaly in contrast to the patients with AVH- B (p<0.05). But jaundice was detected more frequently in patients with AVH- B. The laboratory findings that were noted more in Salmonella patients than AVH- B patients were: left shift of leukocyte, anemia, thrombocytopenia, hypoproteinemia, hypoalbuminemia, lower peak levels of aminotrans ferase and total bilirubin, a trend toward a higher peak level of serum LDH and lower ratio of ALT/LDH expressed as a multiple of the upper limit of normal level on admission (p< 0.05). Acute cholecystitis was complicated in 2 patients with Salmonella. One was resolved by cholecystostomy and the other had surgical intervention. The other 9 patients recovered with appropriate administration of antibiotics. Conclus ion: The clues that raise the poss ibility of Salmonella over AVH- B include: high fever, headache, diarrhea, relative bradycardia, hepatmegaly, left shift of leukocyte, anemia, thrombocytopenia, hypoproteinemia, hypoalbuminemia, a markedly elevated serum level of LDH and lower ALT/LDH ratio (less than 4) on admission. Of these, ALT/LDH ratio is the best discriminator between Salmonella and AVH- B. Early diagnos is and appropriate administration of antibiotics are necessary for the successful treatment of Salmonella.

Sang Wook Choi,Don Hyun Jo,Sung Soo Kim,Jin Mo Yang,Byung Min An,Nam Ik Han,Chang Don Lee,Gyu Won Jung,Hee Sik Sun
Korean J Hepatol 2000;6(4):448-455.
Backgrounds/Aims
This study focuses on the pathogenesis of inflammatory reaction and cell necrosis in patients with chronic viral hepatitis and examines the possible effects of follicular dendritic cells, HLA-DR and CD8+ presenting lymphocytes by analyzing their expression and the histological activity index (HAI) in liver tissues. Methods: Liver biopsy specimens were obtained from 59 patients with chronic hepatitis B and from 26 patients with chronic hepatitis C. The expressions of dendritic cells, HLA-DR and CD8+ presenting lymphocytes were determined by immunohistochemical stain. Results: The incidence of lymphoid follicle and/or lymphoid aggregates in portal tracts of the liver was higher in chronic hepatitis C than it was in chronic hepatitis B (84.6% vs. 15.3%, p=0.000). Follicular dendritic cells were exclusively expressed within lymphoid follicles and/or lymphocyte aggregates in portal areas. HLA-DR restricted cells were mainly observed in portal and periportal areas as well as in the area of piecemeal necrosis. CD8+ lymphocytes were diffusely expressed in portal and periportal areas and within intralobular parenchymal sinusoids. The expression of dendritic cell and HLA-DR was more frequently observed in moderate chronic hepatitis than in mild chronic hepatitis. While that of CD8+ lymphocyte expression was more frequent in severe chronic hepatitis with a high HAI score. Conclusions: The follicular dendritic cells may trap viral antigens in intraportal lymphoid follicle and present them to HLA-DR and CD8+ presenting lymphocytes. It is suggested that the associated expression of dendritic cells, HLA-DR and CD8+ presenting lymphocytes in liver tissues may play one of the biological role in immune injury in chronic viral hepatitis.

The Effect of Lamivudine Therapy for Chronic Liver Disease due to Hepatitis B Virus Infection
Neung Hwa Park,Kwang Ro Joo,Do Ha Kim
Korean J Hepatol 2001;7(1):77-89.
Background/Aims
Lamivudine, an oral nucleoside analogue, effectively suppresses HBV replication and improves liver enzymes as well as liver histology. Long-term lamivudine therapy can induce the emergence of drug resistant HBV strains in some patients. The aim of this study was to evaluate the effects of lamivudine, the breakthrough rate, and the relapse rate of discontinuing therapy after HBeAg loss. Methods: A total of 190 patients with HBeAg and HBV DNA positive showing abnormal serum levels of aminotransferases for at least 6 months received 100 mg of lamivudine once daily. The duration of lamivudine therapy was from 6-36 months (mean 14 months). Responder was defined as the ALT normalization with sustained suppression of HBV DNA and HBeAg loss. Therapy was to be stopped after HBeAg loss. Post-treatment monitoring continued for 1-21 months (mean 6 months). Results: The cumulative HBeAg loss rates at 12 months and 18 months were 35% and 43%, respectively. Pretreatment serum HBeAg quantitation, and the duration of lamivudine therapy were independent predictive factors for HBeAg loss. The cumulative breakthrough rates at 18 and 24 months were 38% and 57%, respectively. Pretreatment HBV DNA level was the only predictable factor for breakthrough. Therapy was discontinued after HBeAg loss in 52 patients. Most episodes of relapse (15/16) occurred within 6 months after cessation of lamivudine. The cumulative relapse rates at 3 months and 6 months were 21% and 50%, respectively. A predictive factor for post-treatment relapse after HBeAg loss was the duration of lamivudine therapy. Conclusions: These results suggested the pretreatment quantitative HBeAg in serum and duration of lamivudine therapy are independent predictive factors for HBeAg loss. The HBeAg response of lamivudine-induced HBeAg loss was not durable after discontinuing therapy.(Korean J Hepatol 2001;7:77-89)

Special Oromucosal Cytokine Therapy : Mechanism(s) of Action
Michael G. Tovey
Korean J Hepatol 2002;8(2):125-131.
Oromucosal cytokine therapy allows large amounts of cytokines to be administered with improved outcome and without dose limiting toxicity. Orally administered cytokines exert their effects by a novel two pronged mechanism of action. Firstly, specific populations of immuno-competent effector cells are activated in the oral cavity and migrate to the site of virus replication. Secondly, chemokines produced in the lymphoid tissue of the oral cavity enter the peripheral circulation and redirect activated lymphocytes to eliminate virus infected cells. Oromucosal IFN therapy constitutes an alternative and improved means of therapy for diseases such as chronic viral hepatitis which are currently treated parenterally with IFNα. The oral route also has obvious advantages for ease of administration and improved patient compliance. Furthermore, the availability of a well tolerated form of IFN therapy will also allow Type I IFNs to be used for the treatment of diseases such as upper respiratory tract virus infections, for which parenteral IFN therapy is currently precluded due to unacceptable toxicity.(Korean J Hepatol 2002;8:125-131)

Jong Ho Park, M.D., Neung Hwa Park, M.D., Jung Woo Shin, M.D., Sung-Jo Bang, M.D., Dae-Hyun Kim, M.D., Kwang Ro Joo, M.D. and Do Ha Kim, M.D.
Korean J Hepatol 2003;9(3):188-197.
Background/Aims
The post-treatment relapse patterns and efficacy of lamivudine re-treatment for relapsed patients have not been clarified. The aims of this study were to evaluate the relapse patterns after discontinuing therapy and the effects of lamivudine re-treatment for relapsed patients after HBeAg seroconversion. Methods: Therapy was discontinued after HBeAg seroconversion in 121 patients. Sixty-six patients were relapsed and included in this study. The duration of lamivudine re-treatment therapy was from 6-35 (mean: 16) months. Post-retreatment monitoring continued for 1-40 (mean: 8,9) months. Results: Among the relapsed 66 patients, 50 (75.8%) had HBeAg reappearance while 16 (24.2%) remained HBeAg negative and anti-HBe positive, The cumulative relapse rates at 3, 6, 12 and 24 months were 27%, 47%, 60% and 66%, respectively, Forty-two relapsers received lamivudine re-treatment, Among them, 33 were HBeAg positive and 9 were HBeAg negative and anti-HBe positive, Response was achieved in 31 of the 42 patients (73.8%). The cumulative response rates at 6, 9 and 12 months were 62%, 69% and 72%, respectively. Six patients (14.3%) developed viral breakthrough, All patients were HBeAg positive chronic hepatitis B. The duration of lamivudine re-treatment was the only predictable factor for response of lamivudine re-treatment. Therapy was discontinued after response in 21 patients, Eleven patients were relapsed, including 6 who were HBeAg positive and 5 who were HBeAg negative. Predictive factors for post-retreatment relapse were age and the duration of additional lamivudine therapy after response, Conclusions: The response rate of lamivudine re-treatment was significantly higher than in initial lamivudine treatments. The response rate of lamivudine re-treatment was significantly higher than in initial lamivudine treatments. The breakthrough and relapse rates, however, were similar in both initial and retreated lamivudine therapy.(Korean J Hepatol 2003;9:188-197)

Park Neunghwa , Sin Jeongu , Park Jongho , Bang Seongjo , Kim Daehyeon , Ju Gwanglo , Kim Doha
Korean J Hepatol 2003;9(4):293-303.
Background/Aims
Long-term treatment with lamivudine causes breakthrough, but the clinical course after lamivudine breakthrough is not well known. The aims of this study were to evaluate the clinical course in lamivudine after breakthrough, and to identify predictive factors of breakthrough. Methods: 124 patients with chronic hepatitis B infection, who represented viral breakthrough during lamivudine therapy, were included. The mean duration of lamivudine therapy and additional lamivudine therapy after breakthrough was 30.5 months and 12.5 months, respectively. Results: The cumulative breakthrough rates at 12, 18, 24 and 36 months were 8, 24, 36 and 52%, respectively. After viral breakthrough, only 4 patients maintained normal ALT levels. 120 patients showed ALT elevation. The number of patients with ALT levels greater than 5 times, and greater than 10 times, the upper normal limit were 67 (56%) and 29 (24%), respectively. While still on lamivudine therapy after breakthrough, 98 patients presented ALT elevation. Only 22 had normalized ALT levels. Hepatic decompensation developed in 2 patients. HBeAg seroconversion after breakthrough occurred in 10 patients. The changing pattern of quantitative HBeAg levels during lamivudine therapy was the only predictive factor associated with viral breakthrough. The mean time of turning points in decrescendo-crescendo patterns of HBeAg levels during lamivudine therapy was earlier than viral breakthrough (9 months vs. 17 months). Conclusions: These results suggested that deterioration of hepatic function can usually be observed after breakthrough. The serial monitoring of serum quantitative HBeAg levels may allow an early recognition of viral breakthrough.(Korean J Hepatol 2003;9:293-303)

Korean J Hepatol 2005;11(3):227-242.
Background/Aims
The therapeutic strategies of applying adefovir for treating lamivudine resistant HBV mutants are controversial. Thus, we observed the clinical outcomes after discontinuation of lamivudine to establish the timing to initiate adefovir therapy. Methods: Fifty chronic hepatitis B (CHB) patients with lamivudine resistant HBV mutants who had received lamivudine for more than 12 months were included in the study. We investigated the clinical outcomes at 6 months after the end of treatment (EOT). We compared the serial clinical outcomes among respective groups based on serum ALT at the EOT and the clinical characteristics of patients with or without acute exacerbation (AE) and the HBeAg loss. We also investigated the predictive parameters of AE and HBeAg loss. Results: Fifteen patients (30%) had experienced AE at 6 months after the EOT. Four patients received antiviral agents because of their hepatic decompensation. Patients with AE had higher serum ALT values and lower HBV DNA titers at EOT compared with those patients without AE. Serum ALT at the EOT was the predictive parameter of AE. Eight patients (21.6%) had newly developed HBeAg loss at 6 months after EOT. The total bilirubin at EOT was the predictive parameter of HBeAg loss. Conclusions: CHB patients with lamivudine resistant HBV mutants had favorable clinical outcomes at 6 months after EOT. Therefore, we can consider observing the clinical courses after discontinuation of lamivudine and it is not always required to overlap the adefovir for treating lamivudine resistant HBV mutants except for the treatment of patients with a high risk of developing decompensation.
