Abstract:

Objective

To provide a meta-analysis of the risk factors of BKV activation after kidney transplantation basing on the related published reports and to provide reference for the prevention and treatment of BKV nephropathy.

Methods

The published papers related to BKV activation after kidney transplantation in the PubMed database, the Chinese journal full-text database, the Wanfang database, and the Chinese biomedical database from the establishment of the database to the July 2019 were systematically searched, and the references of the papers were manually searched for supplemental papers. The quality of each study was evaluated using the Newcastle-Ottawa scale. The data of the risk factors were extracted and meta-analysed by RevMan 5.3 statistical software.

Results

A total of 22 studies were included, 15 of which were English literatures and 7 were Chinese literatures. The results showed that the risk factors of BKV detected in the blood were rejection (OR=1.91, 95%CI: 1.30-2.80), delayed graft function (OR=1.51, 95%CI: 0.99-2.31), taking tacrolimus (OR=1.50, 95%CI: 1.22-1.84), using antithymocyte globulin(ATG) induction (OR: 1.75, 95%CI: 1.02-2.98), using ureteral stent (OR=1.98, 95%CI: 1.19-3.30) and those with CMV infection (OR=2.23, 95%CI: 1.61-3.09); the risk factor of BKV detected in the urine was continuous use of glucocorticoid (OR=1.49, 95%CI: 1.09-2.04).

Conclusions

Kidney transplant recipients taking tacrolimus, co-infection with CMV, using ureteral stent, and using ATG after kidney transplantation have a higher risk of BK viremia, and kidney transplant patients who have taken hormones for a long time have a higher risk of BK viruria.
