Abstract
Background/purpose
Cytomegalovirus (CMV) infection remains a challenge following liver transplantation. Preemptive treatment is an effective strategy for CMV infection. However, how long preemptive treatment should be applied is not defined.
Methods
Clinical records of preemptive treatment for CMV infection in patients who underwent liver transplantation were collected. CMV antigenemia (pp65) was monitored weekly during hospital stay and subsequently on follow up whenever indicated clinically. Antiviral treatment was administered based on positive antigenemia (>1 positive cell per 500,000 leukocytes) and discontinued when antigenemia became negative.
Results
CMV infection was diagnosed in 58 (43.9%) of 132 liver transplantation patients. All 58 patients were seropositive for CMV before transplantation. CMV infection was first diagnosed at a median time of 20 days (interquartile range [IQR] 15.3–26) after transplantation. Twelve (20.7%) patients developed repeated infections. Only one of 58 patients (1.7%) was suspected to have invasive disease. The median (IQR) duration of antiviral treatment was 7 (7–12) days. Of these patients with CMV infection, 14 (24.1%) patients developed acute rejection peri-anti-CMV treatment and 36 (62.1%) developed other infectious complications.
Conclusion
Preemptive treatment is an effective way to halt the progression of asymptomatic CMV infection. A brief course of antiviral treatment is enough for seropositive patients with CMV infection after liver transplantation.
