BACKGROUND:
Hepatitis B is a viral infection that attacks the liver and can cause both potentially life-threatening acute and chronic liver disease. China has the world's largest burden of hepatitis B and is considered to be a major contributor toward the goal of World Health Organization (WHO) of eliminating hepatitis B virus (HBV) as a global health threat by 2030. This study aimed to analyze data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to determine the trends in mortality of liver disease due to hepatitis B in China between 1990 and 2019 and the gap with the WHO's goal.
METHODS:
Annual deaths and age-standardized mortality rates (ASMRs) of liver disease due to hepatitis B in China between 1990 and 2019 were collected from GBD 2019. We calculated the percentage changes in deaths and estimated annual percentage changes (EAPCs) of ASMRs of liver disease due to hepatitis B.
RESULTS:
In China, deaths of total liver disease due to hepatitis B decreased by 29.13% from 229 thousand in 2016 to 162 thousand in 2019, and ASMR decreased by an average of 4.92% (95% confidence interval [CI]: 4.45-5.39%) per year in this period. For the spectrum of liver disease due to hepatitis B, deaths decreased by 74.83%, 34.71%, and 23.34% for acute hepatitis, cirrhosis and other chronic liver diseases, and liver cancer from 1990 to 2019, respectively, and ASMRs of acute hepatitis (EAPC = -7.63; 95% CI: -8.25, -7.00), cirrhosis and other chronic liver diseases (EAPC = -4.15; 95% CI: -4.66, -3.65), and liver cancer (EAPC = -5.17; 95% CI: -6.00, -4.33) decreased between 1990 and 2019. The proportions of older adults aged ≥70 years among all deaths of the spectrum of liver disease due to hepatitis B increased from 1990 to 2019. Deaths of liver cancer due to hepatitis B increased by 7.05% from 2015 to 2019.
CONCLUSIONS
Although a favorable trend in the mortality of liver disease due to hepatitis B was observed between 1990 and 2019, China still faces challenges in achieving the WHO's goal of eliminating HBV as a public threat by 2030. Therefore, efforts to increase the coverage of diagnosis and treatment of liver disease due to hepatitis B, especially of liver cancer due to hepatitis B, are warranted in China.

Hepatitis D virus (HDV) infection causes the most severe form of viral hepatitis with rapid progression to cirrhosis, hepatic decompensation, and hepatocellular carcinoma. Although discovered > 40 years ago, little attention has been paid to this pathogen from both scientific and public communities. However, effectively combating hepatitis D requires advanced scientific knowledge and joint efforts from multi-stakeholders. In this review, we emphasized the recent advances in HDV virology, epidemiology, clinical feature, treatment, and prevention. We not only highlighted the remaining challenges but also the opportunities that can move the field forward.

<b>BACKGROUNDb>Unhygienic blood collection in the early 1990s led to blood-borne infections in Central China. This study aimed to estimate human immunodeficiency virus (HIV) co-infection with hepatitis C and B viruses (HCV and HBV) and their risk factors in a rural area of Shanxi Province with a history of commercial blood donation.
<b>METHODSb>A cross-sectional study was conducted in 2004. All adult residents in the target area were invited to participate in the study. Face-to-face interviews were completed and blood specimens were tested for HIV, HCV, and HBV surface antigen (HBsAg).
<b>RESULTSb>Prevalence rates of HIV, HCV, and HBsAg were 1.3% (40/3 062), 12.7% (389/3 062), and 3.5% (103/2982), respectively. Of the 40 HIV-positive specimens, 85% were HCV positive and 2.5% were HBsAg positive. The history of commercial blood donation was positively associated with HIV, HCV, and HIV/HCV co-infections, but was negatively associated with HBsAg seropositivity. Migration for employment in the last 5 years was positively related to HIV, HBsAg, and HIV/HCV co-infections. Univariate logistic analysis showed that illegal drug use, number of sex partners, extramarital sex behavior, commercial sex behavior, and condom use rate were not related to anti-HIV, anti-HCV, HBsAg seropositivity or their co-infections.
<b>CONCLUSIONb>The history of commercial blood donation was the main risk factor for HIV, HCV, and HIV/HCV co-infections in this former commercial blood donation area. HIV and HCV prevention and treatment interventions are important in this area.

BACKGROUND/AIMS: Alcohol and the hepatitis B virus (HBV) exert synergistic effects in hepatocelluar carcinogenesis. We aimed to elucidate the clinical significance of the antibody to hepatitis B core antigen (anti-HBc) and occult HBV infection on the development of hepatocellular carcinoma (HCC) in patients with alcoholic liver cirrhosis (LC). METHODS: Patients with alcoholic LC alone (n=193) or combined with HCC (n=36), who did not have HBsAg or antibody to hepatitis C virus were enrolled. Clinical data and laboratory data including anti-HBc were investigated at enrollment. The polymerase chain reaction was applied to HBV DNA using sera of patients with HCC or LC after age and sex matching. RESULTS: Patients with HCC were older (60+/-11 years vs. 53+/-10 years, mean+/-SD, P<0.001), more likely to be male (100% vs. 89%, P=0.03), and had a higher positive rate of anti-HBc (91.2% vs. 77.3%, P=0.067), and a higher alcohol intake (739+/-448 kg vs. 603+/-409 kg, P=0.076) than those with LC. Age was the only significant risk factor for HCC revealed by multiple logistic regression analysis (odds ratio, 1.056; P=0.003). The positive rate of anti-HBc and alcohol intake did not differ in age- and sex-matched subjects between the LC (n=32) and HCC (n=31) groups. However, the detection rate of serum HBV DNA was higher in the HCC group (48.4%) than in the LC group (0%, P<0.001). CONCLUSIONS: Anti-HBc positivity is not a risk factor for HCC. However, occult HBV infection may be a risk factor for HCC in patients with alcoholic LC.

<b>OBJECTIVEb>To explore the potential risk factors of intrahepatic cholangiocarcinoma (ICC) in China.
<b>METHODb>A case-control study including 317 patients with pathologically confirmed ICC and 634 healthy individuals was conducted. The cases and controls were matched in age, sex and inhabitancy. Data were statistically analyzed by Chi-square test and conditional logistic regression.
<b>RESULTSb>Univariate analysis showed significant difference in HBsAg seropositivity, liver cirrhosis, hepatolithiasis, choledocholithiasis and schistosomiasis between ICC patients and healthy controls (P < 0.05). Multivariate analysis confirmed that HBsAg seropositivity, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis were associated with ICC, and their adjusted odds ratio (95% confidence interval) were 10.265 (6.676-15.783), 13.101 (5.265-32.604), 18.242 (3.580-92.958), 18.435 (1.930-176.082), 15.102 (4.607-49.499) and 11.820 (3.522-39.668), respectively. The incidence of hepatic cyst, cholecystolithiasis, hepatic hemangioma, fatty liver, diabetes mellitus, smoking and drinking were not significantly different between ICC patients and controls.
<b>CONCLUSIONSb>The HBV infection, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis may be the risk factors for ICC in China.

BACKGROUND AND AIMS: The etiology of acute viral hepatitis in Korea has been dynamically changing during the recent years. The aim of this study was to investigate the recent etiology and the clinical features of acute viral hepatitis in a single center of Korea. METHODS: We performed a retrospective analysis of a prospective cohort of 55 patients who were diagnosed with acute viral hepatitis A to E during the period from May 2005 to August 2006. In addition to the clinically acute manifestations, the confirmatory serological tests were performed for the diagnosis of acute hepatitis A, B, C and E. RESULTS: The proportion of patients with acute viral hepatitis A, B, C, E and others were 56.4% (n=31), 12.7% (n=7), 18.2% (n=10), 9.1% (n=5) and 3.6% (n=2), respectively. The mean age of the patients with acute hepatitis A, B, C and E were 29.1+/-4.38, 38.7+/-11.72, 45.3+/-17.62 and 32.4+/-6.58 years, respectively. There was no fatal case. All cases of acute hepatitis B and six out of ten cases of acute hepatitis C recovered spontaneously. Four out of the five patients with acute hepatitis E had no history of travel to endemic area. CONCLUSIONS: The most common etiology of acute viral hepatitis in Korea is hepatitis A virus, and hepatitis C and B virus were the next most common causes. The sporadic cases of acute hepatitis E were not rare, and coinfection of HAV and HEV was observed. A multicenter, prospective study is warranted in the future.

7.Multicenter report on dialysis and transplantation in Korea, 1986: Korean Society of Nephrology.
Journal of Korean Medical Science 1988;3(4):135-141
Since 1981, the Korean Society of Nephrology began annual report on renal replacement therapy in Korea. The annual number of new patients receiving dialysis treatment in 1986 increased to 957 patients (23.3 per million population) from 825 patients (20.4 per million population) in 1985. And the total number of patients on replacement therapy increased from 1,508 patients (37.3 per million population) to 2,534 patients (61.7 per million population). 1,340 patients (32.6 per million population) of these patients were on hemodialysis, 573 patients (13.9 per million population) on continuous ambulatory peritoneal dialysis (CAPD) and 621 patients (15.1 per million population) on functioning renal graft as of December 31, 1986. The common causes of renal failure of new patients were chronic glomerulonephritis (41.6%) followed by diabetic nephropathy (12.6%), nypertensive nephrosclerosis (7.8%), chronic pyelonephritis (2.5%) and others. The annual mortality rate decreased from 21.9% in 1981 to 13.5 in 1986. The common causes of death in patients on dialysis therapy were cardiac (32.8%), vascular (14.7%), infective (14.7%) and social problems (11.2%) in the order of frequency. Recently, the number of patients requiring dialysis is rapidly increasing due to expanded medical insurance support for dialysis and improved economic status of our country. Therefore, it is necessary to draw up counterplan for a rapid growth of the number of new patients.

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) has been characterized by a wide spectrum of liver damages that span from steatosis to cryptogenic liver cirrhosis and even to hepatocellular carcinoma (HCC). The aims of this study were to determine whether the prevalence of HCC arising from cryptogenic cirrhosis has increased during the last ten years and to characterize the clinical features of cryptogenic HCC in Korea. METHODS: A retrospective and hospital-based analysis of the clinical data was done in 1,145 HCC patients; group A (Jan. 1993-Dec. 1995), group B (Jan. 2000-Dec. 2002). The etiologies of HCC with liver cirrhosis in group A and group B were analyzed. The risk factors of NAFLD such as obesity, type 2 diabetes mellitus, hypertriglyceridemia and hypertension between cryptogenic HCC and HCC with well-defined etiologies were compared. RESULTS: The major leading causes of HCC in each group were hepatitis B virus infection, followed by alcohol, hepatitis C virus and cryptogenic. There was a significant increase in the proportion of cryptogenic HCC in group B (A: 2.3%, B: 5.4%, p<0.05). In the case of HCV, it was 5.3% in group A and 9.9% in group B (p<0.05). Although the prevalence of cyptogenic HCC was significantly increased at an interval of seven years apart, there was no significant difference in the proportions of risk factors of NAFLD between cryptogenic HCC group and well-defined etiology group. CONCLUSIONS: The prevalence of cryptogenic HCC was significantly increased in Korea during the last decade. Although statistically insignifcant, there was a trend toward the higher proportion of risk factors with NAFLD in patients with cryptogenic HCC. This suggests that increased proportion of risk factors associated for NAFLD may have contributed to the development of cryptogenic HCC.

BACKGROUND/AIMS: We investigated factors associated with the disease progression and development of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients during long-term oral nucleos(t)ide analog (NA) therapy. METHODS: This retrospective study included 524 naive CHB patients who received oral NA therapy for more than 48 weeks between January 2003 and December 2007. The primary outcome was 5-year cumulative probability of disease progression and HCC development. Disease progression was defined as cirrhosis development, cirrhotic complications, HCC or liver-related mortality. RESULTS: For the 524 patients, the cumulative probabilities of disease progression and HCC development at 1, 2, 3, 4 and 5 years were 1.1%, 6.3%, 9.0%, 11.6%, and 16.2% and 0.2%, 1.8%, 3.6%, 5.8%, and 9.3%, respectively. In multivariate analysis, age >50 years (hazard ratio [HR], 1.05) and cirrhosis (HR, 2.95) were significant factors for disease progression. Similarly, age >50 years (HR, 1.05), family history of HCC (HR, 5.48), and cirrhosis (HR, 17.16) were significant factors for HCC development. Importantly, longer duration (>12 months) of maintained virological response (<20 IU/mL) reduced the risks of disease progression (HR, 0.19) and HCC development (HR, 0.09). CONCLUSIONS: Longer duration of maintained virological response significantly reduces the risk of disease progression or HCC development in CHB patients undergoing long-term oral NA therapy.
