  • Serum hepatitis is still recognized as a major public health problem in many countries. The most common etiologies are acute viral hepatitis A and B, and hepatitis B virus (HBV) was known as the pathogen of serum hepatitis. since the HBV causes chronic hepatitis. HBV infection is hyperendemic in Korea. It is known that 8% and 1% of the Korean population is chronic carriers of HBV. The total number of 487 serum specimen (old people's home 190, causal ward-Daegu hope village 297) were collected at the laboratory of Department of Clinical Pathology of Daegu medical center. The laboratory tested the specimen to detect for hepatitis B surface antigen (HBsAg) and anti-HBs using reverse passive hemag-glutination (RPHA) and passive hemagglutination (PHA) method between April, 2011 and June, 2011. In one-step test, HBsAg and anti-HBs of Humasis were used. The positive rate for HBsAg was 6.80% (33/487), and the rate in male was 6.93% (19/274) higher than that of female 6.57% (14/213). In the positive rate of HBsAg by age group, the highest positive rate group was in the group of 40-49 years in male (12.0%), and 50-59 years in female (17.65 %). The overall positive rate for anti-HBs was 42.70% (208/487), showing the higher positive rate of 43.80% in male (120/274) than that of 41.30% (88/213) in female. The highest positive rate of anti-HBs in age group was the 40-49 years group in male (52.00%) and the group of under 29 in female (66.67%).

  • 목 적: 비-가족형, 비-대사성, 비-A, B, C형 바이러스성 신생아 간염은 양호한 경과를 취한다고 알려져 있지만, 장기적인 경과 관찰에 대한 연구가 부족하다. 연자들은 이 질환의 임상적 특징을 연구하여 임상 경과 및 예후 예측에 도움을 얻고자 하였다. 방 법: 1998년 1월부터 2004년 1월까지 생후 3개월 이내에 부산대학교병원에서 신생아 간염으로 진단되었던 환자 중 임상 소견 및 생화학적 검사의 이상 소견이 6개월 이상 지속되었던 34명을 대상(A, B, C형 바이러스성, 대사성, 유전성 신생아 간염은 제외)으로 하여 임상적 소견, 검사실 소견 및 조직학적 소견을 병력지와 조직 슬라이드 분석을 통해 후향적으로 연구를 시행하였다. 결 과: 성비는 2.4 : 1로 남아가 많았고, 진단 시 연령은 생후 1~2개월 사이가 가장 많았다. 혈청 ALT의 최고치의 범위는 광범위(100~1,000 IU/L)하였으나, 300 IU/L 미만이 41%였다. 혈청 직접형 빌리루빈의 최고치는 50%에서 1.0~5.0 mg/dL 사이였다. CMV에 대한 IgM 항체 검사 또는 PCR 검사에서 34%가 양성이었다. 추적 기간의 조건을 충족한 29명 중 11명(37.9%)의 환자가 1년 이내에 ALT 수치가 정상화되었고, 1년 이상 ALT 수치가 증가된 환자 13명 중에서는 2년 이내에 정상화된 경우가 9명(69.2%), 2년 이상 지속적으로 상승된 경우가 4명(30.7%)였다. 2년 이상 지속적으로 ALT 수치의 상승이 있었던 경우 간 조직 검사에서 간문맥 주변 섬유화, 간문맥 염증 및 간소엽 염증 등의 변화가 2년 이내에 회복된 경우보다 심했으나 통계학적인 의미는 없었다. 결 론: 비-가족형, 비-대사성, 비-A, B, C형 바이러스성 신생아 간염은 비교적 예후가 양호하지만 혈청 ALT 수치의 상승이 1년 이상 지속 시 간 손상의 정도에 대한 평가와 만성 간질환에 대한 주의 깊은 관찰이 필요하다.

  • 목 적: Transfusion-transmitted virus는 간염과의 연관성이 아직 명확하지 않지만 특정 유전형이 원인불명의 간염 병원체로 작용하거나 다른 간염 바이러스와 중복 감염되어 임상 경과에 영향을 줄 가능성에 대한 연구가 필요하다. 본 연구는 국내 소아 B형 간염, C형 간염 및 원인 불명의 간염 환자의 TTV DNA 양성률과 유전형의 분포를 알아보기 위해 시행하였다. 방 법: 간 기능이 정상인 소아 88명을 대조군으로 하였으며 B형 간염 환자 14명, C형 간염 환아 12명, 2001년 6월부터 2004년 6월까지 인제의대 상계백병원을 방문한 원인 불명의 간염 환자 25명을 대상으로 하였다. 환아의 혈청 검체를 대상으로 N22 시발체를 이용한 PCR과 5'NCR 시발체를 이용한 PCR을 시행하였다. 또한 TLMV DNA 검출을 위한 seminested PCR을 시행 하였다. N22 primer를 이용한 PCR 양성 산물을 대상으로 염기서열의 직접 분석이 시행되었다. 결 과: 1) N22 시발체를 이용한 TTV DNA 양성률은 대조군에서 11.3%, 간염군에서 19.6%였다(p=0.105). B형 간염의 28.5%, C형 간염의 25%, 원인 불명의 간염 24%에서 TTV DNA가 양성이었으며 대조군에 비해 유의한 차이는 없었다. 2) 5'NCR 부위 시발체를 이용한 TTV DNA 양성률은 대조군에서 32.9%, 간염군에서 54.9%였다. B형 간염의 71.4%, C형 간염의 50%, 원인 불명의 간염 48%에서 TTV DNA가 양성이었다. B형 간염 환자군에서 양성률이 대조군에 비해 높았다(p=0.008). 3) 5'NCR 부위 시발체를 이용한 TLMV DNA양성률은 간염 환자군과 정상 대조군에서 각각 29.4% (15/51명), 48.9% (43/88명)였다. B형 간염 21.4% (3/14), C형 간염 16.6% (2/12), 원인 불명의 간염 환자에서 40% (10/25)였다. 4) 염기 서열 분석: N22 시발체를 이용해서 PCR 반응 산물 중 총 29예(간염 환자 8명, 대조군 11명)의 염기서열을 분석한 결과 G1 유전형은 10예(52%)였고 이 중 G1a형이 7예였다. G2 유전형은 3예, G3 유전형은 2예였으며 나머지는 정확한 분류가 되지 않았다. 결 론: 국내 소아에 감염된 TTV 유전형 중 가장 흔한 것은 G1형이었다. TTV DNA 양성률은 대조군과 원인 불명의 간염군 간에 차이는 없었으며, B형 간염군에서 대조군에 비해 높았다.

  • Interferon-${\gamma}$-inducible protein 10 (IP-10), also known as chemokine C-X-C motif ligand (CXCL) 10, is closely associated with antiviral immunity and the progression of chronic hepatitis B (CHB). However, the value of baseline serological and histological IP-10 expression levels in predicting the efficacy of the antiviral response to nucleoside/nucleotide analogues (NAs) is still unknown. In our research, intrahepatic and peripheral IP-10 expression levels were systemically examined before and after treatment with entecavir (ETV). Baseline serological and histological IP-10 expression levels were significantly increased in patients with CHB, particularly in patients with higher degrees of liver inflammation and liver fibrosis. Moreover, higher baseline intrahepatic IP-10 levels indicated better prognoses in patients with CHB after entecavir therapy. The baseline IP-10 level was also positively associated with several clinical parameters, including baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis B virus (HBV) DNA, and hepatitis B surface antigen (HBsAg), and with the decrease in HBsAg levels after treatment. In addition, monocyte-derived IP-10 was expressed at higher levels in patients with CHB than in patients with liver cirrhosis (LC) and healthy controls (HC). According to the results of our in vitro experiments, IP-10 directly promoted hepatocyte apoptosis. Based on these findings, baseline serological and histological IP-10 levels might predict CHB severity and the decrease in HBsAg levels after entecavir therapy.

  • 목적: 소아 만성 B형 간염 환아들에게 라미부딘으로 치료 시작 후 그 치료 효과를 평가하고 소아에서 라미부딘 장기 치료의 지속성과 안정성에 대해 검증하고자 하였다. 대상 및 방법: 1999년 3월부터 경북대학교병원 소아과에서 만성 B형 간염으로 라미부딘 치료를 시작한 후 2004년 9월 현재까지 최소 6개월 이상 치료한 48명(남 31, 여 17명, 1~18세, 평균 8세)을 대상으로 29개월(8~66개월) 추적 관찰하면서 연구를 시행하였다. 치료에 대한 효과는 치료 시작 후 혈청 ALT 치의 정상화와 HBV DNA의 음전 및 HBeAg/anti-HBe로의 혈청전환을 모두 만족할 때 치료반응이 있다고 정의하였다. Kaplan-Meier법을 이용한 누적 HBeAg 혈청전환율을 치료 시작 0.5, 1, 1.5, 2, 2.5, 3년에서 구하였다. 결과: 라미부딘으로 치료 시작 후 0.5년이 경과한 48명 중 치료 반응은 29명(60%)에서 보였고 9명(19%)에서는 HBsAg의 소실도 일어났다. 치료 시작 1년째 ALT치가 정상화된 환아는 94%, HBV DNA치가 음전된 환아는 94%, HBeAg 혈청전환까지 되어 치료 반응이 있던 환아는 34%였다. Kaplan-Meier법에 의한 누적 HBeAg 혈청전환율은 0.5, 1, 1.5, 2, 2.5, 3년째에 각각 13, 34, 50, 68, 79, 90%로 계산되었다. 특히 7세 미만의 소아 22명 중에서는 HBsAg의 소실이 8명(36%)에서 일어나 7세 이상에서 치료를 시작하는 것에 비하여 탁월한 성적을 보여주었다(p=0.002). 결론: 한국의 소아 만성 B형 간염 환아에서 라미부딘의 장기 치료는 HBeAg 혈청전환을 가속화 시키며 3년 동안 추적 관찰 결과 장기적으로 치료 반응이 지속되었다. 소아 만성 간염의 경과 관찰 중 면역제거기에 들어서면 라미부딘으로 장기간 적극적인 치료를 시도하는 것이 좋을 것으로 생각한다.

  • Toxicity study of recombinant hepatitis B vaccine (LBD-008), a newly developed drug for acute and chronic hepatitis, was investigated in mice and guinea pigs. 1. Mice showed no production of antibodies against LBD-008 inoculated with aluminum hydroxide gel (Alum) as an adjuvant, judged by the heterologous anaphylaxis (PCA) test using rats. On the other hand, antibodies against ovalbumin (OVA) inoculated with alum were definitely detected. 2. In the studies with guinea pigs, both the inoculation of LBD-008 only and of LBD-008 with complete Freund's adjuvant (CFA) as an adjuvant did not produce positive reactions in any of homologous active systemic anaphylaxis (ASA). On the other hand, the inoculation of ovalbumin with complete Freund's adjuvant (CFA) produced positive reaction in both of PCA and ASA. 3. These findings suggested that LBD-008 has no antigenic potential in mice or guinea pigs.

  • Hepatocellular carcinoma (HCC) is major health problem with high mortality rates, especially in patients with hepatitis B virus (HBV) infection. Telomerase function is one of common mechanisms affecting genome stability and cancer development. Recent studies demonstrated that genetic polymorphisms of telomerase associated genes such as telomerase associated protein 1 (TEP1) rs1713449 and PIN2/TERF1-interacting telomerase inhibitor 1 (PINX1) rs1469557 may be associated with risk of HCC and other cancers. In this study, 325 patients with HCC and 539 non-HCC groups [193 healthy controls, 80 patients with HBV-related liver cirrhosis (LC) and 266 patients with HBV-related chronic hepatitis (CH)] were enrolled to explore genetic polymorphisms of both SNPs using the allelic discrimination method based on MGB probe TaqMan real time PCR. We demonstrated that all genotypes of both genes were in Hardy-Wienberg equilibrium (P>0.05). Moreover, there was no significant association between rs1713449 genotypes and HCC risk, HCC progression and overall survival (P>0.05). Interestingly, we observed positive association of rs1469557 with risk of HCC when compared with the LC group under dominant (CC versus CT+TT, OR=1.89, 95% CI= 1.06-3.40, P=0.031) and allelic (C versus T alleles, OR=1.75, 95% CI=1.04-2.94, P=0.033) models, respectively. Moreover, overall survival of HCC patients with CC genotype of rs1469557 was significantly higher than non-CC genotype (Log-rank P=0.015). These findings suggest that PINX1 rs1469557 but not TEP1 rs1469557 might play a role in HCC progression in Thai patients with LC and be used as the prognosis marker to predict overall survival in HCC patients.

  • MicroRNAs directly and indirectly influence many biological processes such as apoptosis, cell maintenance, and immune responses, impacting on tumor genesis and metastasis. They modulate gene expression at the posttranscriptional level and are associated with progression of liver disease. Hepatocellular carcinoma (HCC) is a cancer which mostly occurs in males. There are many factors affect HCC development, for example, hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV), co-infection, environmental factors including alcohol, aflatoxin consumption and host-related factors such as age, gender immune response, microRNA and single nucleotide polymorphisms (SNPs). Chronic infection with the hepatitis B virus is the major factor leading to HCC progression since it causes the liver injury. At present, there are many reports regarding the association of SNPs on miRNAs and the HCC progression. In this research, we investigated the role of miR-149 (rs2292832) and miR-101-1 (rs7536540) with HCC progression in Thai population. The study included 289 Thai subjects including 104 HCC patients, 90 patients with chronic hepatitis B virus infection (CHB) and 95 healthy control subjects. The allele and genotype of rs2292832 and rs7536540 polymorphisms were determined by TaqMan real-time PCR assay. Our results revealed no significant association between miR-149 (rs2292832) and miR-101-1 (rs7536540) and the risk of HCC in our Thai population. However, this research is the first study of miR-149 (rs2292832) and miR-101-1 (rs7536540) in HCC in Thai populations and the results need to be confirmed with a larger population.

  • In this study, we investigated the correlation between the administration of various antiviral agents and the alternation of specific biomarkers induced by the hepatitis B virus (HBV). Eligible subjects diagnosed with chronic hepatitis B were prescribed with antiviral drugs at the Gastroenterology Internal Medicine Department of E University Hospital in Daejeon between May 2004 and September 2009. Lamivudine was prescribed to 66 out of 100 patients. Of the 12 patients, 6 (50.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 39 patients, 23 (59.0%) showed higher than 40 IU/L alanine aminotransferase (ALT). Of the 65 patients, 41 (63.1%) showed HBV DNA decrease of 1 log, and were prescribed with Lamivudine. Adefovir was prescribed to 3 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative, and was prescribed with Adefovir. Entecavir was prescribed to 19 (19.0%) out of 100 patients. Of the 12 patients, 3 (25.0%) showed a change from being HBe-antigen-positive to being HBe-antigen-negative. Of the 12 patients, 3 (125.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 14 (21.5%) showed HBV DNA decrease of 1 log, and were prescribed with Entecavir. Clavudine was prescribed to 7 out of 100 patients. Of the 12 patients, 1 (8.3%) showed a change from positive HBe antigen to negative HBe antigen. Of the 39 patients, 5 (12.8%) showed higher than 40 IU/L ALT. Of the 65 patients, 6 (9.2%) showed HBV decrease of 1 log, and were prescribed with Clavudine. These results do not show a statistically significant correlation between drugs and biomarkers. Data on combination therapy using Lamivudine and Adefovir show no statistically significant difference between drugs and biomarkers. Medications for periodic inspection was not correlated to HBe-antigen-negative conversion, ALT, and HBV DNA. HBV DNA was significantly reduced in patients with high levels of AST(aspartic acid aminotransferase) and ALT before treatment. In addition, the decrease of HBV DNA after 12 months of treatment was less frequently observed in patients treated with Lamivudine compared with other drugs. This result is associated with Lamivudine resistance. Although the association of drugs with diagnostic markers and the correct choice of treatment is difficult to determine, these results may be useful for further research on diagnosis and treatment of the hepatitis B virus.
