초록

배경: TT virus (TV)는 건강인에서 매우 높은 빈도로 검출되는 바이러스로서 B형 간염 바이러스 (HBV) 및 C형 간염 바이러스(HCV)에 감염된 환자에서도 빈번하게 발견된다 . 이 연구에서는 국내 건강 성인과 HBV 및 HCV 감염자를 대상으로 여러 가지 시발체에 따른 TTV DNA의 양성률을 조사하고자 하였다 . 방법: 건강 성인 69예, HBV 감염자 59예, HCV 감염자 34예의 혈청 검체를 대상으로 하였다 . 이중중합효소연쇄반응(nested PCR)법으로 TTV DNA를 검사하였고, 각각 TTV의 N22 유전자 부위, 5 untranslated region (UTR), 3 UTR을 증폭시키는 3가지 시발체 조합을 사용하였다 . 결과: 전체적인 TTV 양성률은 N22 유전자 부위의 시발체를 사용한 경우 43%, 5 UTR 시발체를 사용한 경우 69%, 3 UTR 시발체를 사용한 경우 64% 였다. 각각의 시발체에 따른 TTV 양성률은 건강 성인군과 HBV 및 HCV 감염자군 사이에 유의한 차이를 보이지 않았다 . 결론: TTV 양성률은 5’ UTR과 3’ UTR 시발체를 사용한 경우가 N22 유전자 부위의 시발체를 사용한 경우보다 높았고, 건강 성인군과 HBV 및 HCV 감염자군 사이에 차이를 보이지 않았다.

Abstract

Background: TT virus (TTV) infection is highly prevalent in the general population and in the patients infected with hepatitis B virus (HBV) or hepatitis C vius (HCV). The aim of the present study was to assess the positive rates of TTV DNA using different PCR primer sets in healthy and HBV or HCV-infected individuals in Korea. Methods: TTV DNA was investigated in serum samples of 69 healthy individuals and 59 HBV-infected and 34 HCV-infected individuals by nested PCR assays using primers from N22 region, 5'-untranslated region (UTR), and 3' UTR of viral genome. Results: TTV DNA was detected in 43% of total study populations using N22 primers, in 69% using 5' UTR primers and, in 64% using 3' UTR primers. No significant difference was observed in the positive rates of TTV DNA between healthy and HBV or HCV-infected individuals. Conclusion: The PCR assays for TTV DNA using 5' UTR primers and 3' UTR primers exhibited higher positive rates than that of the assay using N22 primers without any significant difference between healthy and HBV or HCV-infected individuals.
