BACKGROUND/AIMS: The genotype of hepatitis B virus (HBV) has been suggested to correlate with the clinical outcome of HBV infection. We analyzed the distribution of HBV genotypes according to the clinical outcomes of HBV infection in Jeju island. METHODS: A total of 145 HBsAg-positive samples were enrolled. To identify specific patterns of HBV genotypes, we performed restriction fragment length polymorphism (RFLP). In the case that typical restriction pattern of RFLP was not determined, phylogenetic analysis was performed. RESULTS: RFLP analysis was possible in 65 patients. Clinical diagnoses of the 65 patients with chronic liver disease were as follows: HBeAg-positive healthy carrier (HBeAg+, anti-HBe, HBV DNA+, transaminase normal; n=20); Inactive HBsAg carrier (n=12); chronic hepatitis B (n=14); liver cirrhosis (n=9); hepatocellular carcinoma (n=10). Sixty-two patients showed a typical restriction pattern by HinfI. However, 3 patients showed a unique restriction pattern by HinfI, which were not reported in the literature. When phylogenetic analysis was performed to classify the genotype of these 3 patients, they were also genotype C. However, all 65 patients showed typical restriction patterns by Tsp509I, which were reported in genotype C. CONCLUSIONS: All chronic HBV infections are genotype C in Jeju island regardless of clinical outcomes.

OBJECTIVETo investigate the distribution of hepatitis B virus genotype in Hubei province (China) and its clinical significance.
METHODSSerum samples from 190 HBV DNA positive patients with chronic HBV infection,including 52 asymptomatic HBV carriers (ASC), 56 chronic hepatitis (CH), 32 fulminant hepatic failure (FHF), 22 liver cirrhosis (LC), and 28 hepatocellular carcinoma (HCC) patients were collected and tested for HBV genotypes by type-specific primers.
RESULTSA simple and precise genotyping system based on PCR using type-specific primers was developed for the determination of genotypes of hepatitis B virus (HBV). Of the 190 patients, 140 (73.7%) were genotype B and 42 (22.1%) were genotype C. Genotype B was more prevalent in the FHF and HCC patients than in the ASC patients; the ALT value was significantly higher in genotype B than in genotype C patients. The rate of anti-HBe was significantly higher in genotype B than in genotype C except in the patients of the ASC group.
CONCLUSIONThe system we used seems to be a useful tool for the molecular diagnosis of HBV infection and for large-scale surveys. Genotype B, genotype C and BC combination exist in Hubei province, and genotype B is the major genotype in this area especially in FHF and HCC patients.

5.Prevalence and Clinical Significance of Diabetes Mellitus in Patients with Liver Cirrhosis.
The Korean Journal of Hepatology 2003;9(3):205-211
BACKGROUND/AIMS: Impaired glucose tolerance and overt diabetes mellitus (DM) frequently occurs in patients with chronic liver disease. Hyperinsulinaemia and peripheral insulin resistance contribute to the development of DM in these patients. The clinical relevance, however, of DM to their clinical course was not determined. We investigated the prevalence of DM in patients with liver cirrhosis and their clinical characteristics and prognosis. METHODS: A total of 606 consecutive cirrhotic patients were enrolled for 5 years. We reviewed all laboratory findings, clinical courses, and mortality, retrospectively. The cirrhotic patients were divided into two groups according to the presence of DM, and their clinical characteristics and mortality were compared. DM was diagnosed in accordance with National Diabetes Data Group criteria. RESULTS: Among the total of 606 cirrhotic patients (M:F, 482:124), 346 (57.1%) had HBV related disease and 60 (10%) had HCV related disease. Forty-five percent of the patients had a history of habitual drinking. DM was observed in 22.4% of the cirrhotic patients. In the diabetic group, the frequency of HCV infection was significantly greater. DM did not affect survival. The DM group, however, appeared to have higher mortality in the patients with Child-Pugh class A cirrhosis during long-term follow up. Only 20.6% of the diabetic patients had normal range blood glucose levels even though most of them received medical therapy. The cases with well controlled blood glucose showed higher survival than poorly controlled cases n the DM group. CONCLUSIONS: Cirrhotic patients have a high prevalence of DM, and more frequently are associated with HCV infection. The strict control of blood glucose and the control of infection could be important in prolonging the survival in compensated cirrhotic patients with DM.

6.Current Status and Clinical Course of Hepatitis C Virus in Korea.
The Korean Journal of Gastroenterology 2008;51(6):360-367
The mortality due to chronic liver disease, including liver cirrhosis and hepatocellular carcinoma (HCC), ranks as one of the highest in Korea. The prevalence rates of hepatitis C virus (HCV) and hepatitis B virus (HBV) infections in the general Korean population are approximately 1 and 5%, respectively. Blood transfusion was the strongest risk factor for the transmission of HCV infection. Therefore, the evaluation of risk factors for HCV infection including blood transfusion, intravenous drug user, hemophilia, and hemodialysis, is important. The most prevalent HCV genotype is 1b followed by 2a. The annual incidence of HCC among HCV-related liver cirrhosis has been estimated at 5%, and approximately 12% of HCC is attributable to HCV and 68% to HBV in Korea. HCV infection is more closely associated with HCC in elderly patients than HBV-related HCC. Even though the prevalence of anti-HCV in Korea has been reduced and the risk of HCV transmission through blood transfusion has markedly decreased, public-health programs to prevent de novo infections should be developed. This review describes the HCV prevalence and risk factors among the general population, and the distribution of HCV genotypes as well as the clinical course of HCV in Korea.

PURPOSE: Spontaneous bacterial peritonitis (SBP) frequently develops in patients with liver cirrhosis; however, there is little data to suggest whether the acquisition site of infection influences the prognosis. This study compared the bacteriology, clinical characteristics and treatment outcomes of community-acquired SBP (CA-SBP) and nosocomial SBP (N-SBP). MATERIALS AND METHODS: The medical records of 130 patients with hepatitis B virus (HBV)-related liver cirrhosis, who had experienced a first episode of SBP between January 1999 and December 2008, were reviewed. RESULTS: The study population included 111 (85.4%) patients with CA-SBP and 19 (14.6%) patients with N-SBP. Baseline and microbiological characteristics as well as clinical course, including in-hospital mortality, did not differ between patients with CA-SBP and those with N-SBP (all p>0.05). The median survival time was 6.5 months, and 117 (90.0%) patients died during the follow-up period. Patients with CA-SBP and N-SBP survived for median periods of 6.6 and 6.2 months, respectively, without significant difference (p=0.569). Time to recurrence did not differ between patients with CA-SBP and N-SBP (4.7 vs. 3.6 months, p=0.925). CONCLUSION: The acquisition site of infection did not affect clinical outcomes for patients with HBV-related liver cirrhosis who had experienced their first episode of SBP. Third-generation cephalosporins may be effective in empirically treating these patients, regardless of the acquisition site of the infection.

OBJECTIVETo understand the influence of HIV infection on hepatitis C progress in patients co-infected with HIV and hepatitis C virus (HCV) and related immune mechanism.
METHODSTwenty eight patients co-infected with HIV/HCV and 12 patients with simplex HCV infection were enrolled. The liver function and hepatic fibrosis progress were evaluated by detecting peripheral blood and with Fibro-Scan. The viral load of HCV was detected by using real time quantitative PCR. And the percentage of Treg/CD4⁺ T lymphocyte cell was tested by using flow cytometry.
RESULTSThe levels of ALT and ALP in HIV/HCV co-infection group were (76.16 ± 81.248) U/L, (24.507 1 ± 8.194) g/L respectively, higher than those of simplex HCV infection group [(27.475 0 ± 13.985) U/L, (16.966 7 ± 7.189) g/L], the differences were statistical significant. P value was 0.012 and 0.009 respectively. The liver fibrosis index in HIV/HCV co-infection group was 5.950 0-5.825 0 Kpa, higher than that in simplex HIV infection group (5.150 0-1.050 0 Kpa), and the difference was nearly statistical significant (P = 0.077). The HCV viral load in HIV/HCV co-infection group was (6.476 8-5.343 4) lg copy/ml, higher than that in simplex HCV infection group [(1.699 0-2.681 5) lg copy/ml], and the rate of HCV clearance in HIV/HCV co-infection group was 32.14%, lower than that in simplex HCV infection group (75.00%). P value was 0.012 and 0.032 respectively. The percentage of Treg/CD4⁺ T lymphocyte cell in HIV/HCV co-infection group was (7.460 0%-2.287 5%), higher than that in simplex HCV infection group (5.965 0%-2.105 0%), and the difference was significant (P = 0.032). The percentage of Treg/CD4⁺ T lymphocyte cell was significantly related with HCV viral load (ρ = 0.350, P = 0.027), and HCV viral load was significantly related with the liver fibrosis index (ρ = 0.487, P = 0.001).
CONCLUSIONHIV infection could accelerate the progress of hepatitis C, and Treg cells were involved in this progress.
