Study of Covalently Closed Circular DNA (cccDNA) in Liver Transplant Patients With B Virus Markers

Completed
Conditions
Liver Transplantation
Interventions
Biological: cccDNA assay on liver biopsy
Registration Number
NCT02602847
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

The aim of this study is to validate in the context of liver transplantation, the interest of the cccDNA assay technique developed by the team of Professor Zoulim (INSERM U1052) on liver biopsy and correlate this assay cccDNA in hepatitis B virus (HBV) viral load and serum liver through several groups of patients at transplantation (on graft and native liver explant) and after transplantation.

Primary Outcome Measures
NameTimeMethod
cccDNA rate on native explant and liver transplant during transplantation and on liver biopsy1 year after transplantation

cccDNA rate will be assessed on native explant and liver transplant during transplantation and on liver biopsy (between M1 to M3 and 12 months (M12) after transplantation) to study the colonization of new hepatocytes by HBV

Secondary Outcome Measures
NameTimeMethod
Correlation between cccDNA rate and virologic status1 year after transplantation

Correlation of cccDNA assay with serologic and virologic status (AgHBe, HBV DNA, ...) will be assessed at the moment of the transplantation and during post-transplantation period and HBV recurrence

Correlation between cccDNA rate and serologic status1 year after transplantation

Correlation of cccDNA rate with serologic and virologic status (AgHBe, HBV DNA, ...) at the moment of the transplantation and during post-transplantation period and HBV recurrence

Correlation between cccDNA rate and patient's treatment1 year after transplantation

Correlation of cccDNA rate with patients' treatments will be assessed at the moment of the transplantation and during post-transplantation period and HBV recurrence
