Impact of cytomegalovirus reactivation just before liver transplantation: A prospective cohort study

BACKGROUND

Cytomegalovirus (CMV) is the most common viral pathogen after liver transplantation (LT). Although reactivation of CMV infection is generally described in the context of immunosuppression, it has also been described in critically ill immunocompetent patients including cirrhotic patients.

AIM

To determine the incidence of reactivated CMV prior to LT.

METHODS

This was a prospective cohort study evaluating adult patients who underwent LT between 2014 and 2016. A plasma sample was obtained from all patients for CMV quantitative real-time PCR testing right before transplantation. Patients were followed for at least 1 year to assess the following outcomes: Incidence of CMV infection, organ rejection and overall mortality.

RESULTS

A total of 72 patients were enrolled. Four patients died before transplantation, thus 68 patients were followed up for a median of 44 mo (20-50 mo). In 23/72 patients (31.9%) CMV was reactivated before transplantation. Post-transplantation, 16/68 (23.5%) patients had CMV infection and that was significantly associated with the recipient being CMV negative and a CMV-positive donor. Pre-transplant CMV reactivation was not associated with overall mortality (log rank: 0.9).

CONCLUSION

This study shows that CMV infection is common in patients with chronic liver disease just before LT, but the clinical impact of this infection seems to be negligible.

Duct-enterostomy as a treatment of pancreatic fistula in a bladder-drained pancreas transplant

A case of combined pancreaticoduodeno-renal transplant with good graft function was complicated by recurrent episodes of graft pancreatitis treated by vesical catheter drainage. Four months after transplantation, a fistula from the pancreatic body associated with ascitis was identified. Anastomosis between pancreatic fistula and an individualized jejunal loop was performed. The duodenocystostomy was not disconnected. A splint placed inside the wirsung was exteriorized percutaneously through the jejunal loop and removed 30 days after the operation. Both kidney and pancreas grafts are functioning normally 2 years after transplantation.
