Abstract

Human cytomegalovirus (HCMV) reactivation is a common complication after liver transplantation (LT). Here, we investigated whether human leukocyte antigen (HLA)-matching was related to HCMV infection and subsequent graft failure after LT for hepatitis B virus cirrhosis. This retrospective study reviewed 91 LT recipients. All the patients were grouped according to HLA-A, HLA-B, and HLA-DR locus matching. Clinical data were collected, including complete HLA-typing, HCMV viremia, graft failure, and the time of HCMV viremia. HLA typing was performed using a sequence-specific primer-polymerase chain reaction kit. HCMV was detected by pp65 antigenemia using a commercial kit. The incidence of HCMV infection post-LT was 81.32%. Graft failure was observed in 16 of 91 (17.6%) patients during the 4-year study. The incidence of HCMV viremia was 100% (5/5), 91.4% (32/35), and 72.5% (37/51) in HLA-A two locus, one locus, and zero locus compatibility, respectively. Nevertheless, the degree of the HLA-A, HLA-B, or HLA-DR match did not influence the time of HCMV viremia, graft failure, or the time of graft failure after a diagnosis of HCMV viremia (all P > 0.05). An interesting discovery was that the risk of HCMV viremia tended to be higher in patients with better HLA-A compatibility. Graft failure, time of HCMV viremia, and graft failure after a diagnosis of HCMV viremia appear to be independent of HLA allele compatibility.
