Background: This study aimed to explore the risk factors for BK virus (BKV) infection in renal transplant recipients (RTRs) routinely treated with tacrolimus.
Methods: Forty-two cases with BKV infections and 51 patients without BKV infections were enrolled in the study. Eighty-seven healthy individuals and 77 patients undergoing dialysis were randomly included as controls. A logistic regression model was used to analyze potential variables in order to evaluate factors related to BKV infection in the renal transplant recipients.
Results: The number of individuals with acute rejection in BKV positive RTRs is significantly higher than that in BKV negative RTRs. Hemoglobin levels in BKV positive RTRs were significantly lower than those in BKV negative RTRs (109.61 ± 20.11 vs. 130.16 ± 26.297, p < 0.001). There was a positive correlation between tacrolimus levels and hemoglobin concentration in RTRs (r = 0.329, p = 0.023). The results of a multivariate regression analysis indicated that a history of acute rejection (OR = 4.157, p = 0.031) and low hemoglobin (OR = 0.963, p < 0.001) were risk factors for BKV infection.
Conclusions: Acute rejection and low hemoglobin were risk factors for BKV infection after renal transplantation.
