  • We here document discovery of expression profile of myeloid derived suppressor cells (MDSCs) in chronic hepatitis B (CHB) patients and changes in the course of disease. The study population was composed of 75 outpatient HBV cases and 15 healthy control cases. Peripheral blood samples were collected for separation of mononuclear cells. Levels of MDSCs labeled with Lin-DR-CD11b+CD33+ obtained from peripheral blood mononuclear cells (PBMC), were revealed to have significant differences between the CHB and other groups. They were 0.414% for health control cases and 0.226% for CHB cases (Z=-2.356, p=0.0189). It also observed that the group of HBeAg positive cases had significant difference in MDSCs/PBMC median ($X^2=11.877$, p=0.003), compared with group of HBeAg negative cases and the healthy control group. It suggested considerable MDSCs might be involved in HBeAg immune tolerance. In addition, negative correlations between MDSCs/PBMC and parameters of ALT, AST and TBil, while positive correlation between MDSCs/PBMC and ALB parameter were found. Multiple comparisons between the four phases and health control phase again, there was a statistically sifnificant difference ($X^2=17.198$, p=0.002). Taken together, these findings may provide a new immunotherapy strategy for reduced the expression levels of MDSCs in CHB patients, through induction of an autoimmune response to virus removal.

  • 목 적: 만성 B형 간염 환자의 치료에 interferon alfa는 효과가 있는 것으로 알려지고 있지만 연구자에 따라 차이가 있으며 소아에서의 치료 후의 조직학적 변화에 대한 연구는 거의 없는 실정이다. 저자들은 소아 만성 B형 간염에서 interferon alfa의 치료 효과와 추적 생검이 가능했던 환자에서의 조직학적 변화에 대해 알아보고자 하였다. 대상 및 방법: 1995년 3월부터 1997년 8월까지 서울대학교병원 소아과에서 6개월 이상 HBsAg과 HBeAg 및 HBV DNA가 양성이었으며 간 조직검사상 만성 간염으로 확진된 환자 35명을 대상으로 recombinant interferon alfa 3~6 MU(평균 $3.4\;MU/m^2$)를 주 3회씩 6개월간 피하주사 하였다. 치료 시작 12개월 이상 혈청학적 변화를 추적 관찰하였다. interferon에 반응이 있는 환자 중 18명에서 치료후 간생검을 실시하여 조직학적 변화를 분석하였다. 결 과: 1) 치료 환자 35명 중 17명(49%)에서 인터페론 치료 시작 6개월에 HBV DNA의 감소가 있었고, 12개월째에 22명(63%)에서 HBeAg 및 HBV DNA의 음전이 생겼으며 18개월까지는 25명(71%)에서 관찰되었다. 반응군에서 혈청 ALT치는 모두 정상화되었고, HBsAg의 음전은 1명에서 관찰되었다. 2) 어머니가 HBsAg 보유자가 아닌 수평감염, 치료전 ALT가 정상의 2배 이상, 간조직의 심한 괴사와 염증이 interferon에 대한 반응이 좋은 예측인자이었다. 3) 치료 후 반응군의 간조직 소견에서 간맥주위괴사, 소엽내 활성도, 간맥내 염증, 간섬유화, total HAI가 유의하게 감소하였다. 결 론: 소아 만성 B형 간염에서 interferon alfa 치료 후 63%에서 반응을 보였으며, 혈청학적 변화는 조직학적 소견의 호전과 연관이 있다. 소아 만성B형 간염 환아에서 interferon 치료는 혈청학적, 생화학적, 조직학적 관해를 유도하는 효과적이고 안전한 치료방법이다.

  • 목 적: 인터페론은 소아 만성 B형 간염의 치료에 널리 쓰이고 있으나 50% 이상의 환자에서 인터페론 치료에 반응이 없어 추가적인 다른 치료가 필요하다. 라미부딘은 B형 간염 바이러스 복제의 억제제로 B형 간염 치료제로 널리 쓰이고 있으나, 인터페론 치료에 반응이 없었던 B형 간염 환자에 대한 라미부딘의 치료 효과에 대한 연구가 많지 않다. 방 법: 2000년 1월부터 2007년 12월까지 부산대학교병원 소아청소년과에서 만성 B형 간염으로 진단되어 인터페론(interferon ${\alpha}$-2b, 10 $MU/m^2$ 또는 pegylated interferon $1.5{\mu}g/kg$)으로 6개월 간 치료를 받은 33명 중 치료에 반응이 없어 치료 종결 후 6~12개월 뒤부터 라미부딘(3 mg/kg/일, 최고 100 mg/일)으로 치료를 한 8명(남 6명, 여 2명)을 대상으로 라미부딘의 치료 효과를 분석하였다. 임상적 소견에 대해 의무기록지를 후향적으로 검토하였다. 결 과: 인터페론 치료 시작 시 나이는 4.9${\pm}$3.1세, 라미부딘 치료 시작 시 나이는 6.1${\pm}$3.2세였다. 인터페론 치료 전 혈청 ALT는 148.1${\pm}$105.8 IU/L였고, HBV-DNA PCR log값은 6.95${\pm}$0.70 copies/mL였다. 인터페론 치료 후 ALT는 143.1${\pm}$90.4 IU/L였고, DNA PCR log값은 6.46${\pm}$2.08 copies/mL로 치료 전과 차이가 없었고(p> 0.05), 2명에서 HBeAg 음전이 있었다. 모든 환자에서 라미부딘 치료 후 7.4${\pm}$2.1개월에 ALT가 정상화되고, 이미 HBeAg이 음전된 2명을 제외한 6명에서 7.9${\pm}$2.1개월에 HBeAg 혈청전환이 있었다. HBV DNA는 2.4${\pm}$2.8개월에 7명(87.5%)에서 음성화되었다. 2명은 라미부딘치료 종결 후 3년 이상 재발이 없으며, 5명은 완전 반응상태로 24.4${\pm}$9.1개월간 복용 중이다. 1명은 12개월간 라미부딘을 복용하여 혈청 ALT가 정상화되고 HBeAg 혈청전환이 있었으나 바이러스 돌파현상이 발생하여 치료를 중단하였다. 결 론: 연구 대상 환자 수가 적었지만 인터페론 치료에 반응이 없었던 만성 B형 간염 환자에서 라미부딘의 치료는 매우 효과적이었다.

  • 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.

  • Hepatitis B virus (HBV) infection is contagious with transmissiobn vertically or horizontally by blood products and body secretions. Over 50% of Iranian carriers contracted the infection prenatally, making this the most likely route of transmission of HBV in Iran. To evaluate the resistance to adefovir (ADV) therapy in patients with chronic hepatitis B infection, a study was conducted on 70 patients (63 males and 7 females), who had received in first line lamivudine and second line adefovir. All were tested for the presence of hepatitis B surface antigen (HBsAg), hepatitis B envelope antigen (HBeAg), serum alanine amino transferase (ALT) level and HBV DNA load before and after treatment with ADV. In all samples, resistance to lamivudine and ADV was tested with real time PCR. Among seventy patients with chronic hepatitis B infection, 18 (25.7%) were resistant to LAM and 8 (11.4%) were resistant to ADV. Only one patient was negative for the presence of HBS-Ag (5.6%) and two were negative for HBe-Ag (11.1%). In this study we used a new method (ALLGIO probe assay) that has high sensitivity in detection of adefovir resistance mutants, which we recommend to other researchers. Mutant strains of the YMDD motif of HBV polymerase can be found in some patients under treatment with lamivudine and ADV. ADV has been demonstrated to be efficient in patients with lamivudine resistant HBV.

  • HBV infection is contagious and may be transmitted vertically or horizontally by blood products and body secretions. Over 50% of Iranian carriers have contracted the infection prenatally, making this the most likely route of transmission of HBV in Iran. This study assesses the resistance to Lamivudine in patients with chronic hepatitis B infection using a new ZNA probe Real Time PCR method. To evaluate the effectiveness of Lamivudine therapy for chronic hepatitis B infection, a study was conducted on 70 patients (63 men and 7women), who had received the drug first line. All patients were tested for the presence of HBsAg and HBeAg, the serum ALT level and the HBV DNA load before and after treatment. In all samples resistance to Lamivudine was tested with the ZNA Probe. Our results showed that ZNA Probe Real Time PCR method could detect wild type,YMDD, and its mutants, tyrosine-isoleucine-aspartate-aspartate and tyrosine-valine-aspartate-Aspartate. Among an estimated seventy patients with chronic hepatitis B infection, 18 (25.7%) were resistant to lamivudine. Only one patient was negative for presence of HBS-Ag (5.6%) and two patients were negative for HBe-Ag (11.1%). Real-time PCR with Zip nucleic acid probes is a sensitive, specific and rapid detection method for mutations in the YMDD motif, which will be essential for monitoring patients undergoing Lamivudine antiviral therapy.

  • The purpose of this study was to provide basic data on hepatitis B infection control in the community through the results of the hepatitis B surface antigen and antibody tests conducted at the Cheongyang-County Health Medical Center. From 2012 to 2020, we retrospectively analyzed the HBsAg, HBsAb, HBeAg, HBeAb, and HBV DNA results of 7,329 hepatitis B-related testers. Among 7,329 subjects, the HBsAg positivity rate was 1.7%, and the positivity rate according to age was the highest at 4.4% in their 30s, 4.2% in their 40s, 4.1% in their 50s, 2.0% in their 60s, 1.9% in their 70s and over, and 10 it was shown in the order of 0.3% from less than large. The HBsAb positivity rate was 43.1% for men, 38.2% for men, and 46.7% for women (P<0.001). To summarize the above results, for infection control of hepatitis B in Cheongyang-County, hepatitis surface antigen proton management is required for those in their 30s or older, and it is thought that efforts to acquire immunity are necessary for those in their 20s or younger.
