Abstract

Background: BK virus-associated nephropathy (BKVAN), caused by infection with or reactivation of BK virus, remains a challenge in kidney transplantation. Screening is recommended for all kidney transplant recipients. For those with clinically significant infection, reduction of immunosuppression is the cornerstone of management. There is no specific antiviral or immunomodulatory therapy sufficiently effective for routine use.

Objectives: This review aimed to examine the benefits and harms of interventions for BK virus infection in kidney transplant recipients.

Search methods: We searched the Cochrane Kidney and Transplant Register of Studies up to 5 September 2024 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

Selection criteria: All randomised controlled trials (RCTs) and cohort studies investigating any intervention for the treatment or prevention of BKVAN for kidney transplant recipients.

Data collection and analysis: Two authors independently assessed the study quality and extracted data. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes and mean difference (MD) and 95% CI for continuous…
