Ito Y, Hino T, Honda A, Kurokawa M. Fluoroquinolones for BK viral complication after transplantation: Meta-analysis. Transpl Infect Dis 2020; 22:e13433. [PMID: 32744404 DOI: 10.1111/tid.13433] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 07/24/2020] [Accepted: 07/24/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVES BK polyomavirus (BKV) causes two distinct complications after transplantation, hemorrhagic cystitis (BKV-HC) after hematopoietic stem cell transplantation (HSCT), and BKV-associated nephropathy (BKVAN) after kidney transplantation (KT). Although fluoroquinolones show efficacy against BKV proliferation in vitro, the clinical effect remains uncertain; thus, we performed meta-analysis to assess its efficacy in the prophylaxis. METHODS Articles published before March 2020 were searched from PubMed, the Cochrane Library, ISRCTN registry, and ClinicalTrials.gov. Primary outcomes were BKV-HC after HSCT and BKVAN after KT. Secondary outcomes were BK viremia, viruria after KT, and fluoroquinolone-related adverse events. RESULTS Three trials with 281 patients post-HSCT and 11 trials with 1882 patients post KT were included as for prophylaxis. Fluoroquinolone prophylaxis did not show effects on BKV-HC (OR 0.54, 95% CI 0.13-2.25), BKVAN (OR 0.74, 95% CI 0.35-1.55), and BK viremia (OR 0.79, 95% CI 0.49-1.28), but significantly decreased BK viruria (OR 0.64, 95% CI 0.45-0.91). Fluoroquinolone prophylaxis was associated with the higher percentage of fluoroquinolone-resistant infection among identified bacteria (OR 2.38, 95% CI 1.16-4.88), but the incidence of fluoroquinolone-resistant infection was similar (OR 1.15, 95% CI 0.71-1.86), due to the decrease of infection itself (OR 0.52, 95% CI 0.34-0.81). CONCLUSIONS This meta-analysis showed that fluoroquinolones did not prevent BKV-HC after HSCT or BKVAN after KT, although the effect against BKV-HC should be further investigated by randomized controlled trials. Fluoroquinolones could reduce the rate of BK viruria to some extent but may not have clinically sufficient effects.

Abstract
In the context of transplantation with the use of immunosuppressive drugs, BK virus infection has become the main cause of BK virus nephropathy(BKVN) in renal transplant recipients(KTRs). More importantly, BKVN may cause further allograft dysfunction and loss. However, the role of the immune microenvironment in the pathogenesis of BKVN remains unknown. Therefore, we collected microarray data of KTRs to elucidate the immune characteristics of BKVN. Via the CIBERSORT, we found that BKVN had relatively more activated memory CD4 T cells. Immunostaining showed that CD4+ and CD8+cells were significantly different between BKVN and stable allografts(STAs). In addition, the expression of immune-related genes(antigen presentation, cytotoxicity, and inflammation) was significantly higher in BKVN than in STAs. The results of gene set enrichment analysis(GSEA) and single-sample GSEA(ssGSEA) indicated that immune cell-,cytokine-,chemokine-, and inflammation-related pathways were significantly activated in BKVN, while metabolism- and renal development-related pathways were significantly downregulated in BKVN. In addition, the immune microenvironments of the peripheral blood in patients with BK viremia(BKV) or transplant kidney biopsy(TKB) with BKVN may be different. Overall, the immune microenvironment may play important roles in the occurrence and development of BKVN and provide a theoretical basis for preventing the occurrence of BKVN and finding novel treatments.

Ciprofloxacin for BK viremia prophylaxis in kidney transplant recipients: Results of a prospective, double-blind, randomized, placebo-controlled trial. Am J Transplant 2019; 19:1831-1837. [PMID: 30811872 DOI: 10.1111/ajt.15328] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 01/18/2019] [Accepted: 02/06/2019] [Indexed: 01/25/2023]
Abstract
In kidney transplantation, BK virus infection has historically resulted in high rates of graft dysfunction and graft loss. Unlike other opportunistic infections, no therapies have been shown to prevent BK. The purpose of the current study was to evaluate the safety and efficacy of ciprofloxacin for the prevention of BK viremia in kidney transplant recipients. Two hundred kidney transplant recipients were enrolled in a prospective, randomized, double-blind, placebo-controlled trial comparing a 3-month course of ciprofloxacin (n = 133) vs placebo (n = 67) for the prevention of BK viremia. The primary endpoint of BK viremia at month 6 posttransplant occurred in 25 (18.8%) patients in the ciprofloxacin group and 5 (7.5%) in the placebo group (P = .03). Higher rates of BK viremia (23.3% vs 11.9%; P = .06) and BK nephropathy (5.8% vs 1.5%; P = .26) remained at 12 months in the ciprofloxacin group. Ciprofloxacin use was associated with a significantly higher rate of fluoroquinolone-resistant gram-negative infections (83.3% vs 50%; P = .04). A 3-month course of ciprofloxacin was ineffective at preventing BK viremia in kidney transplant recipients and was associated with an increased risk of fluoroquinolone-resistant infections. Clinical trial registration number: NCT01789203.

Abstract
BK virus (BKV) can cause graft dysfunction or failure in kidney transplant recipients and hemorrhagic cystitis in allogeneic hematopoietic stem cell transplant patients. BKV-associated nephropathy (BKVAN) emerged as a common complication in the late 1990s, probably due to the introduction of potent immunosuppressive agents. BKVAN occurred in up to 5% of kidney transplant recipients, with graft failure in up to 70%. Since universal implementation of effective screening and treatment strategies, BKV is no longer a common cause of graft failure; reported graft loss is only 0% to 5%. This article briefly describes BK virology, epidemiology, diagnosis, and management.

Impact of donor BK polyomavirus replication on recipient infections in living donor transplantation. Transpl Infect Dis 2018; 20:e12917.

Abstract
BACKGROUND Multiple risk factors for BK polyomavirus (BKPyV) replication after kidney transplantation have been described. Here, we investigated the impact of living donors' urinary BKPyV shedding and recipients' BKPyV antibody status pre-transplant on BKPyV replication during the first year post-transplantation. METHODS We assessed a cohort of living kidney donors and their paired recipients (n = 121). All donors were tested before transplantation, and recipients were tested before and after transplantation for BKPyV viruria and viremia. BKPyV-specific serology was assessed in all recipients at transplantation. RESULTS Ten of 121 donors (8.3%) had urinary BKPyV shedding pre-transplant, none had viremia. Overall, 33 (27.3%) recipients developed viruria after transplantation: 7 had received a kidney from a donor with BK viruria (7/10 positive donors) and 26 had received a kidney from a donor without BK viruria (26/111 negative donors; P = .0015). Fifteen (12.4%) recipients developed BK viremia after transplantation: 3 received a kidney from a donor with viruria (3/10 positive donors, 30%) and 12 received a kidney from a donor without viruria (12/111 negative donors, 11%; P = .08). One patient developed proven nephropathy. Ninety-one percent of recipients were seropositive for BKPyV. No relationship between recipients' sero-reactivity at transplantation and post-transplant BKPyV replication was observed. Pre-transplant donor urinary shedding was an independent risk factor for post-transplant BKPyV replication. CONCLUSION Screening living kidney donors for BKPyV can identify recipients at higher risk for BKPyV replication after transplantation who may benefit from intensified post-transplant screening and treatment strategies.

Abstract
PURPOSE OF REVIEW BK virus is a significant risk factor for kidney allograft dysfunction and loss among renal transplant recipients. Currently, there is no proven effective treatment except for the reduction of immunosuppression. In this review, we discuss diagnostic challenges and current treatment options for BK in kidney transplant recipients. RECENT FINDINGS Antiviral and antibiotic therapies have been employed for BK viraemia with variable efficacy. In addition, novel therapeutic regimens such as adoptive transfer of targeted T cells have been described as possible treatment options for recipients with BK nephropathy. BK can also be seen in the native kidneys of pancreas, heart, lung and liver transplant recipients, suggesting that BK screening measures should be employed to other solid organ transplant recipients. SUMMARY Early screening for BK combined with reduction of immunosuppression remains the mainstay of treatment for BK viraemia. New therapeutic advances demonstrate promise in vitro; however, the in-vivo efficacy will be demonstrated by future studies.

Abstract
BK polyomavirus (BKV) is a challenging problem for the transplant nephrologist. Various strategies have been used to prevent or treat BK virus nephropathy (BKVN). These include reduction in immunosuppression, intravenous immune globulin, cidofovir, leflunomide, and the fluoroquinolone antibiotics. All these agents have their own toxicities. Great interest was shown to use fluoroquinolones to prevent BKVN after its useful experience was reported in bone marrow transplant. Fluoroquinolones being cheap and easily available, attracted nephrologists to use it, for prevention of BKVN. These agents have been shown in vitro studies to be effective. However, there are mixed results about their effectiveness in prevention of BKVN in clinical setting. This review will focus the evidence available for using fluoroquinolones in prevention of BKVN and its usefulness. Furthermore, a way forward to use these agents or not for prevention of BKVN will also be discussed.

Abstract
BK polyomavirus (BKV) causes frequent infections during childhood and establishes persistent infections within renal tubular cells and the uroepithelium, with minimal clinical implications. However, reactivation of BKV in immunocompromised individuals following renal or hematopoietic stem cell transplantation may cause serious complications, including BKV-associated nephropathy (BKVAN), ureteric stenosis, or hemorrhagic cystitis. Implementation of more potent immunosuppression and increased posttransplant surveillance has resulted in a higher incidence of BKVAN. Antiviral immunity plays a crucial role in controlling BKV replication, and our increasing knowledge about host-virus interactions has led to the development of improved diagnostic tools and clinical management strategies. Currently, there are no effective antiviral agents for BKV infection, and the mainstay of managing reactivation is reduction of immunosuppression. Development of immune-based therapies to combat BKV may provide new and exciting opportunities for the successful treatment of BKV-associated complications.
