Objectives : The purpose of this study was to determine correlation between coping strategies to disease and quality of life in chrome viral B hepatitis patients ; to investigate difference of coping strategies to disease and quality in life between chronic viral B hepatitis patients and normal persons ; and to identify major variables related to quality in life of chronic viral B hepatitis patients. Methods: The authors used Weisman coping strategy scale for measuring coping ability and efficacies, and the questionnaire for measuring quality of life including physical, psychological, social and economical aspects and satisfaction of sexual life was made by authors based on related literatures. Data were collected through questionnaire survey over a period from Sep 15, 1994 to Nov 11, 1994. Subjects served for this study consisted of 94 chronic viral B hepatitis patients visited to department of internal medicine at one general hospital and 100 normal persons visited to one general hospital for routine check up of health. The collected data were analyzed by SAS and the statistical methods for analysis were Chisquare, t-test and multiple regression analysis. Results : 1) It was revealed that coping strategies to disease significantly correlated to individual's quality of life. 2) There was no significant difference in coping strategies to disease between chronic viral B hepatitis patients and normal persons. However, chronic viral B hepatitis patients showed the lower scroes of quality of life in physical, psychological and economical aspects. 3) The most important variables which were influenced upon quality of life were coping strategies to disease and satisfaction of sexual life. That is, the more active coping strategies to diseases and the higher satisfaction of sexual life, consequently the higher quality of life was. Especially male patient group or normal persons showed each other the higher scores of quality of life in physical and psychological area than female group or patient group. 4) No statistically significant difference in coping strategies to disease and quality of life was found between HBeAg positive group and HBeAg negative group. Conclusions : The authors suggest that chronic viral B hepatitis patients may show the lower score of quality of life than normal person. Therefore, quality of life assessment should become an integral part of all clinical area that seek to assess the effectiveness of treatment. Also, through the interdisciplinary approach, a comprehensive paradigm that can better account for the effects of chronic disease on the individual' s quality of life should be developed.

In the past, hepatitis B virus (HBV) infection was endemic in the general Korean population. The association of HBV infection with the occurrence of liver cancer has been well demonstrated in several epidemiologic studies. While the mortality rates of liver cancer in Korea have decreased steadily over the last decade, the presence of hepatitis B surface antigen (HBsAg) in mothers remains high at 3-4%, and 25.5% of these HBsAg positive mothers are positive for hepatitis B e antigen (HBeAg). HBV infection caused almost a quarter of hepatocellular carcinoma (HCC) cases and one-third of deaths from HCC. These aspects of HBV infection prompted the Korean government to create a vaccination program against HBV in the early 1980s. In 1995, the Communicable Disease Prevention Act (CDPA) was reformed, and the government increased the number of HBV vaccines in the National Immunization Program (NIP), driving the vaccination rate up to 95%. In 2000, the National Health Insurance Act (NHIA) was enacted, which provided increased resources for the prevention of perinatal HBV infection. Then in 2002, the Korean government, in conjunction with the Korean Medical Association (KMA), launched an HBV perinatal transmission prevention program. The prevalence of HBsAg in children had been high (4-5%) in the early 1980s, but had dropped to below 1% in 1995, and finally reached 0.2% in 2006 after the NIP had been implemented. After the success of the NIP, Korea finally obtained its first certification of achievement from the Western Pacific Regional Office of the World Health Organization (WPRO-WHO) for reaching its goal for HBV control. An age-period-cohort analysis showed a significant reduction in the liver cancer mortality rate in children and adolescents after the NIP had been implemented. In addition to its vaccination efforts, Korea launched the National Cancer Screening Program (NCSP) for 5 leading sites of cancer, including the liver, in 1999. As a consequence of this program, the 5-year liver cancer survival rate increased from 13.2% (1996-2000) to 23.3% (2003-2008). The development of both the primary and secondary prevention for liver cancer including HBV immunization and cancer screening has been of critical importance.

Adefovir dipivoxil which was originally developed by Gilead Sciences has been used as treatments of HIV and HBV, especially a therapeutics for HBeAg positive and negative chronic patients. We developed highly efficient purification method using reverse phase column chromatography for mass production and a stable amorphous Adefovir dipivoxil using solid dispersion method. Reverse phase column chromatography led to highly pure product, more than 99.7% by HPLC and can be used for mass production compared with normal column chromatography. Solid dispersion method containing watersoluble polymer and Isomalt showed improved stability of amorphous Adefovir dipivoxil against heat and moisture.

Although there have been many studies investigating possible associations between the C1653T mutation and risk of HCC, the results have been inconsistent. We conducted searches of the published literature in Pubmed and Embase databases up to January 2013. Seventeen studies with a total of 1,085 HCC cases and 1,365 healthy controls were retrieved. We found a significant association between the C1653T mutation and HCC risk (OR = 2.01, 95%CI= 1.49-2.70). In the subgroup analysis by ethnicity, a significant association was also found in Asians (OR = 2.07, 95%CI= 1.71-2.51). In subgroup analysis by HBV genotype, B and C were linked with development of HCC (B:OR = 2.21, 95%CI= 1.13-4.34; C:OR = 2.26, 95%CI= 1.61-3.16). However, no significant association was found between the C1653T mutation and HCC risk in HBeAg positive cases. In conclusion, this meta-analysis suggests that the C1653T mutation may be associated with susceptibility to HCC.

목적 : 1998년 한국인 성인에서의 혈청 HBsAg의 양성률을 추정하는 것을 일차적 목적으로 하며, HBsAg 양성률의 연령별로 분포, 지역적 차이, 과거 간질환력, 만성간질환 가족력 및 예방접종과의 관련성을 파악하며 또한 양성자를 6개월간 추적후 재검사 하여 B형 간염의 만성보균율을 파악하고자 하는 것을 이차적 목적으로 하였다. 방법 : 1998년 전국 10개 지역에서 의료보험관리공단의 정기건강검진 수진자를 대상으로 하여 HBsAg의 혈청유병률을 조사하였다. HBsAg 양성인 사람들을 대상으로 6개월 이상 추적조사하여 B형간염 만성보균율을 파악하였다. 총 1,816명에 대한 혈청과 설문서가 수집되었다. HBsAg는 RIA로 측정하였다. 결과 : HBsAg의 혈청유병률은 5.5%(95% CI-4.5-6.6)였으며 남자에서 7.4%(95% CI=5.8-9.4), 여자에서 3.6%(95% CI=2.5-5.0)로 나타났다. 급성간질환 과거력과 만성간질환 가족력을 HBsAg 혈청검사결과와 비교한 결과 유의한 관련성이 있는 것으로 나타났다. HBsAg 양성자에서 6개월 후에 음성으로 전환한 사람은 3.2%(95% CI=0.1-16.7)였으며 따라서 B형간염의 만성보균율은 5.3%(95% CI=3.7-6.6)로 추정되었다. 결론 : 본 연구결과에서는 HBsAg의 양성률이 1980년대의 연구결과들에 비하여 비교적 낮게 추정되었으며 이는 특히 여성과 젊은 연령층에서 두드러지게 나타났다. 그러나 우리나라에서의 간암 및 만성간질환의 공중보건학적 중요성을 고려하면 지속적인 간염발생의 예방대책이 필요하다고 할 수 있다.

연구배경: 감염증의 발생여부는 장기이식환자의 예후에 중요한 영향을 미친다. 국내와 같이 결핵의 유병률이 높은 지역에서는 장기이식후 기회감염으로 결핵 발병의 위험성이 높을 것으로 추정되나 아직 간 또는 심장이식환자에서의 결핵의 발병률 및 임상양상에 대한 보고가 부족하거나 없다. 방 법: 1992년 1월 부터 2004년 7월까지 서울아산병원에서 간 또는 심장이식을 받은 840명(간이식 730 예, 심장이식 110예)을 대상으로 의무기록을 후향적으로 분석하였다. 결 과: 국내의 한 대학병원에서 간이식 후 결핵의 발생률은 1.5% (추적 $26.6{\pm}19.8$개월), 심장이식은 2.7% (추적 $59.7{\pm}33.3$개월)였다. 이것은 과거 보고된 국내 신장이식 환자들에서의 결핵 유병률보다는 낮은 것으로 추정된다. 폐외결핵이 35% (속립성 결핵 14%)를 차지하여 기존의 보고들과 같이 폐외결핵의 발병률이 높았다. 간이식 환자에서 결핵발병의 위험인자는 단변수 분석에서 이식 후 당뇨, 낮은 이식 전 백혈구 수치, 만성거부반응이었고, HBeAg 양성은 경계수준의 유의성을 보였다. 대부분의 이식환자에서 결핵 예방 치료가 시행되지 않았고, 결핵이 발생한 대다수의 환자는 리팜핀을 포함한 1차 약제로 치료하였고, 항결핵치료와 연관된 급성 거부반응은 2예에서 관찰되었다. 결 론: 국내의 한 대학병원에서 간 또는 심장이식 후 결핵의 발생률은 각각 1.5%, 2.7%로 결핵의 유병률이 낮은 국가에서의 이식 후 결핵 발병률 보다 높았으며 폐외결핵이 많았다.
