Tt Virus Infection Among Renal Transplant Recipients.
Hepatology Research(1998)
摘要
To clarify the prevalence of TT virus (TTV) infection in renal transplant recipients and to estimate the role of TTV in patients with post-transplant liver function abnormalities, TTV-DNA of 47 renal transplant recipients was screened by polymerase chain reaction (PCR) according to a method described by Okamoto et al. before and after the renal transplantation. One of them was positive for hepatitis B surface antigen (HBsAg), one was positive for anti-hepatitis C virus (HCV) and other 45 were negative for both HBsAg and anti-HCV. TTV-DNA was detected in 22 of 47 patients before renal transplantation, and nine became positive after transplantation. All 47 patients showed a normal level of ALT before transplantation. Three of nine (33%) who became positive for TTV-DNA after transplantation and three of 16 (19%) who were negative for TTV-DNA before and after transplantation showed transient elevation of ALT. These results indicate that TTV was highly prevalent among renal transplant recipients, but a clear association between TTV and post-transplant liver function abnormality was not found.
