저자들은 급성간염 39예, 만성간염 79예, 간경변증 30예, 원발성간암 16예, 보유자 14예 및 비교군 129예의 모두 307명을 대상으로 하여 SGOT, SGPT 및 HBV 표식자를 조사하여 다음의 결과를 얻었다. 1. HBsAg의 발현율은 급성간염의 66.7%, 만성간염의 63.3%, 간경변증의 36.7%, 원발성간암의 81.3% 및 비교군에서 27.1%인 것으로 나타났다. 2. AntiHBc의 발현율은 급성간염의 0%, 만성간염의 21.5%, 간경변증의 36.7%, 원발성간암의 31.3%, 보유자의 0% 및 비교군에서 44.2%로 나타났다. 3. HBeAg은 만성간질환중 만성간염에서 45.6%로 가장 높게 나타났고 AntiHBe는 원발성간암에서 56.3%로 가장 높았다. 4. AntiHBc는 각종 간질환, 보유자 및 비교군에서 높게 나타났으며 이는 AntiHBc자체는 간질환에 직접 관계가 없는 감염의 흔적으로 생각된다. 5. HBsAg 보유자 14명중 6명(42.3%)에서 혈청 GOT, SPT 치의 이상 상승이 있었다. 6. HBV에 감염된 혈청학적 증거가 있으면서 간기능에 이상이 있을 때, HBV 이외에 non-A, non-B 바이러스, Delta agent 또는 타 바이러스나 관련된 다른 요인과의 관계가 있을 수 있는 점을 고려하여야 할 것으로 생각된다. HBV의 5 가지 표식 자가 모두 음성으로 나타난 환자는 급성간염의 5.1%, 만성간염의 5.1%에 달했으며, 이것은 HBV 이외의 다른 원인이 병인이 될 수 있음을 시사하며 비교군 중 SGOT, SGPT치의 증가를 보인 군에서는 17.6%, 정상 SGOT, SGPT치를 나타낸 군에서는 12.8%에서 모든 HBV 표식자가 음성으로 나타났다.

B형 간염 표면항원(HBsAg)의 4가지 주요 아형 조사를 통해 HBsAg과 B형 간염표면항체가 모두 양성인 환자에서 항원과 항체의 아형이 다름을 밝힘으로 항원-항체 공존을 이해하게 되었으며, 감염경로를 추적하는 역학적 조사, 인구이동양상의 지표에 유용하게 사용될 수 있다. 현재까지 우리나라의 HBV 아형에 관한 연구는 전체적인 빈도의 조사나 HBsAg과 anti-HBs가 공존하는 경우에서 아형이 가지는 의미에 대한 것이 전부였다. 본 연구에서는 영남대학교 의과대학 부속병원에서 만성 간질환으로 진단받고 경과추적중인 HBsAg 양성인 환자 214명을 대상으로 혈청에 존재하는 HBsAg 아형을 단세포군 항체를 이용한 혈청학적 방법으로 조사하였다. 214명의 검체중 206명(93.9%)에서 adr, 6명(2.8%)에서 adw, 2명(0.9%)에서 ayr, 2명(0.9%)에서 ar, 3명(1.4%)에서 adwr로 나타났으며 ayw는 한 례에서도 발견되지 않았다. 아형과 질환의 중증도 사이에는 유의한 연관성은 발견되지 않았다. 결론적으로 만성 간질환 환자에서 adr이 가장 많고 질환의 중증도와 아형간에 유의한 연관성은 발견되지 않았지만, 아형이 만성 B형 바이러스 간염의 간경변증이나 간세포암으로의 진행과 예후에 영향을 미치는지 밝히기 위해서는 좀 더 연구를 진행하여야 할 것이다.

목적: 본 연구의 목적은 치료제를 복용하는 만성 B형간염환자의 혈청에서 seroconversion되는 과정 중에 불안정하게 나타나는 HBeAg과 HBeAb 사례를 연구하여, 검사자가 검사결과에 대한 정확한 이해를 하는데 도움을 주고자 하는 것이다. 방법: 만성 B형간염 환자로 진단을 받고 치료제를 복용하고 HBeAg 검사와 HBeAb검사를 시행한 3명을 대상으로 하였다. HBeAg과 HBeAb검사는 Radioimmunoassay법과 Immunoradiometric assay법으로 실시되었다. 결과: HBeAg이 음성화되는 과정에서 결과가 양성에서 음성으로, 다시 양성으로 불안정한 결과를 보였다. HBeAb가 양성화되는 과정에서 결과가 음성에서 양성으로, 다시 음성으로 변하는 불안정한 결과를 보였다. 결론: 이번 사례는 seroconversion 유도를 위해 약물치료중인 만성 B형간염 환자에서 볼 수 있는 불안정한 HBeAg과 HBeAb 혈액 결과이다. 불안정한 HBeAg과 HBeAb 검사 결과를 통하여 검사자는 환자가 바이러스 치료제를 복용하여 seroconversion되는 과정 중에 있을 수 있다는 것과 불안정한 결과는 치료제에 의해 일어나는 자연스러운 현상임을 알 수 있다.

Background: The aims of this study were to evaluate the diagnostic and prognostic roles of serum osteopontin (OPN) and single nucleotide polymorphisms (SNPs) in the OPN promoter in patients with hepatitis B-related hepatocellular carcinoma (HCC). Materials and Methods: Four groups were studied, which included 157 patients with HCC, 73 with liver cirrhosis (LC) and 97 with chronic hepatitis (CH), along with 80 healthy subjects. Serum OPN and alpha-fetoprotein (AFP) levels were measured. The SNPs -66 T/G, -156 G/${\Delta}G$ and -433 C/T within the OPN promoter were determined by direct sequencing. Results: Serum OPN levels were significantly higher in patients with HCC than in the other groups. Area under receiver operating characteristics curves in distinguishing HCC from chronic liver disease (CLD; CH and LC) were 0.782 (95% CI; 0.729-0.834) for OPN and 0.888 (95% CI; 0.850-0.927) for AFP. Using the optimal cut-off value (70 ng/mL), OPN had sensitivity and specificity of 72% and 71%, respectively. Serum OPN was superior to AFP in detecting early-stage HCC (68% vs. 46%). A combination of both markers yielded an improved sensitivity for detecting early HCC to 82%. A high OPN level was significantly correlated with advanced BCLC stage and was an independent prognostic factor for HCC. The SNPs -156 and -443 were associated with susceptibility to HCC, but were not related to overall survival. Conclusions: Serum OPN is a useful diagnostic and prognostic marker for HCC. The combined use of serum OPN and AFP improved the diagnosis of early HCC. Genetic variation in the OPN promoter is associated with the risk, but not the prognosis of HCC.

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.

Purpose: The aim of this study was to examine patients with Chronic Hepatitis B (CHB) and their level of knowledge of their disease, uncertainty, stress and health behaviors and to identify factors influencing their health behavior. Methods: A cross-sectional, descriptive design was used. The sample included 136 patients in a gastroenterology outpatient department at one hospital located in Seoul. The mean age of the subjects was 41 and 77.2% were male. Data were collected using a structured questionnaire from April to June 2009. The collected data were analyzed using SPSS/WIN 15.0. Results: The reported scores for knowledge of the disease, uncertainty, stress, and health behaviors were 14.43, 81.50, 26.50, 52.11, respectively. There were statistically difference between health behaviors and gender, age, marital status and antivirus treatment. A positive correlation existed between knowledge of disease and health behaviors (r=.199, p=.020). In contrast, there was a negative correlation between uncertainty and health behaviors (r=-.250, p=.003). The factors influencing health behaviors were knowledge of disease, gender, age, uncertainty, antivirus treatment, and marital status ($R^2$=.267, p<.001). Conclusion: These findings support that strategies for enhancing knowledge of disease and reducing uncertainty are needed to promote health behavior in patients with CHB.

Background: Chronic infection with hepatitis B virus (HBV) affects about 350 million people worldwide, which have a high risk of development of cirrhosis and hepatocellular carcinoma. Treatment of chronic HBV infection relies on IFN-${\alpha}$ or lamivudine. However, interferon-${\alpha}$ is effective in only about 30% of patients. Also, the occurrence of escape mutations limits the usage of lamivudine. Therefore, the development and evaluation of new compounds or approaches are urgent. Methods: We comparatively evaluated DNA and adenoviral vaccines expressing HBV antigens, either alone or in combined regimens, for their ability to elicit Th1-type immune responses in Balb / c mice which are believed to be suited to resolve HBV infection. The vaccines were tested with or without a genetically engineered IL-12 (mIL-12 N220L) which was shown to enhance sustained Th1-type immune responses in HCV E2 DNA vaccine. Results: Considering the Th1-type cytokine secretion and the IgG2a titers, the strongest Th1-type immune response was elicited by the DNA prime-adenovirus boost regimen in the presence of mIL-12 N220L. In addition, the codelivery of mIL-12 N220L modulated differentially the immune responses by different vaccination regimens. Conclusion: Our results suggest that the DNA prime-adenovirus boost regimen in the presence of mIL-12 N220L may be the best candidate for HBV vaccine therapy of the regimens tested in this study and will be worthwhile being evaluated in chronic HBV patients.

Background: Hepatocellular carcinoma (HCC) is one of the most common cancers in men and the third most common cancer in woman in Thailand. This retrospective study was designed to assess the prevalence, clinical manifestations, treatment outcomes and prognosis of HCC in the central region of Thailand. Materials and Methods: The authors retrospectively reviewed all HCC patients aged more than 15 years old in Thammasat university hospital (TUH) during the period from January 2007 to December 2012. Clinical information, biochemical tests and radiologic findings were collected from review of medical records. Results: There were 308 patients with HCC, which accounted for the prevalence of 5.19% of all cancers diagnosed in TUH during the study period. Of these, 125 (40.5%) had complete information retrievable from their medical records and met the inclusion criteria, 99 (79.2%) were males. The mean age was 57.4 years. A quarter of HCC patients in this study presented without any symptom before diagnosis. The common clinical presentations in the remaining patients were hepatomegaly 64/125 (51.2%), abdominal pain 56/125 (44.8%) and ascites 16/125 (20.8%). Cirrhosis was seen in almost all patients (92.8%). The most common causes of HCC in this study were chronic hepatitis B (49.6%) and C (19.2%). Based on Barcelona Clinic Liver Cancer staging, 75.4% presented at intermediate or late stage. Patients receiving curative therapy with either surgical treatment or radiofrequency ablation had significantly longer survival time after the HCC diagnosis than the palliative therapy group (11.0 months vs 4.0 months, p value= 0.004). The mean survival time after the HCC diagnosis was 10.5 months. Conclusions: The common causes of HCC in central region of Thailand were chronic hepatitis B and C. Surgical therapy or RFA seemed to provide better outcomes than other treatments but only in patients with early stage lesions. Most of the patients in this study presented with advanced diseases and had grave prognosis. Appropriate screening patients at risk for HCC might be an appropriate way to achieve early diagnosis and improve the treatment outcome.

Purpose: The purpose of this study was to explore the experiences of people with chronic hepatitis B (CHB) in Korea. The specific aim was to identify major problems that people with CHB face and strategies that they are dealing with. Methods: A grounded theory method was utilized. The data were collected by individual in-depth interviews from 12 CHB patients from one of the major hospitals in Korea. Results: After constant comparative analysis, a core category emerged as "illness management with self-reliance and will." Seven major strategies that were identified in dealing with the illness were maintaining receptive and positive attitudes; restraining excessive work and greed; searching for information; controlling illness information; adhering to practices for not spreading the viral disease; abstaining from alcohol and smoking and maintaining healthy eating habits; nd using alternative therapies. The outcomes that result from employing these strategies were identified as burden, depression and helplessness, stress for maintaining compliance, and dispirited interpersonal relationships. Conclusion: The results of this study suggest that most people with CHB in Korea have problems in psychosocial area. Thus health professionals need to provide not only informational support but also emotional one to improve quality of life of the people with CHB.
