Bladder malignancy in the kidney transplant recipient is rare and compared with the general population tends to be of high grade and have an aggressive clinical course. In this report, we describe a case of urothelial carcinoma developing in a kidney transplant recipient 6 years after the diagnosis of polyomavirus nephropathy (PVN). BK virus (BKV) DNA was identified in urine and serum by PCR. T...
The infection by the BK Polyomavirus (BKV) is an emerging problem in kidney transplants that contributes to a chronic loss of kidney grafts, and in which immunosuppression plays a decisive role. Understanding its risk factors and strictly monitoring urine and serological markers of the infection could mitigate the undesirable effects of this disease. In this review, we investigate the clinical ...
Viral infections have been associated with increased risk of non-Hodgkin's lymphoma (NHL). We conducted a nested case-control study to investigate the association between prediagnostic serum antibodies to the human polyomaviruses, JC (JCV) and BK (BKV), and subsequent risk of NHL. Two research serum banks were established in Washington County, Maryland, in 1974 and 1989, with the collection of ...
BACKGROUND BK virus-associated nephropathy (BKVAN) is one of the most common viral diseases affecting renal allografts. Screening for viral replication may allow for earlier intervention with reduced allograft loss. A plasma viral load >10(4) copies/mL of BKV DNA is recommended for a presumed diagnosis of BKVAN. METHODS We monitored BKV load on serum and urine samples by Real-Time TaqMan PCR ...
BACKGROUND BK virus is a polyoma virus causing renal allograft nephropathy. Reduction of immunosuppression with the early recognition of significant BK viral loads in urine and plasma can effectively prevent BKV associated nephropathy (BKVN), however the optimal compartment and frequency of BK viral load measurement post renal transplantation are undetermined. Our purpose was to examine time to...
Primary BK virus (BKV) infections acquired mainly during childhood are usually asymptomatic. Several studies revealed its seroprevalence in adult population as high as 90% worldwide. Following primary infection, virus persists as latent infection in the urogenital tract. In renal transplant recipients, primary infection and reactivations affect 10% of patients and without treatment, more than h...
BK virus-associated nephropathy (BKVAN) is one of the major causes of allograft dysfunction in kidney transplant (KT) patients. We compared BKVAN combined with acute rejection (BKVAN/AR) with BKVAN alone in KT patients. We retrospectively analyzed biopsy-proven BKVAN in KT patients from 2000 to 2011 at Seoul National University Hospital. Among 414 biopsies from 951 patients, biopsy-proven BKVAN...
