Abstract

Abstract Purpose A case of BK nephropathy in a kidney transplant recipient who received an organ from a hepatitis C virus (HCV)–positive donor is reported. Summary A 66-year-old male negative for HCV with chronic kidney disease secondary to diabetic glomerulosclerosis received a kidney transplant from an HCV-viremic donor. His initial postoperative course was uncomplicated, and HCV treatment with glecaprevir/pibrentasvir was initiated after discharge. On postoperative day (POD) 60, the patient developed BK viremia and his mycophenolate mofetil dose was decreased. Over the next few months, the BK viral load increased, with mycophenolate mofetil stopped and the tacrolimus goal lowered in response. On POD 130, the patient was admitted for a hypertensive crisis and found to have decreased renal function. During this hospitalization, the patient received a course of intravenous immune globulin (IVIG). Despite an initial response to the modification of immunosuppression therapy and several courses of IVIG over the following months, the patient’s renal function continued to decline. At 18 months after transplantation, the patient was restarted on dialysis and taken off all immunosuppression. Conclusion Utilization of organs from HCV-positive donors in HCV-negative recipients allows for expansion of the donor pool and facilitates shorter times on the waitlist. Although initial data in HCV-discordant transplantation did not find an increased risk for opportunistic infections, more recent studies have shown that such risk may be present. This case report describes a patient who developed BK viremia and eventual allograft failure after an HCV-discordant transplantation.
