Polyomavirus BK reactivation is common in renal transplant recipients and may cause nephropathy with significant graft dysfunction. The induction of anti-double stranded DNA (anti-dsDNA) antibodies by BKV has been described in experimental animals and during primary infection, and has been implicated in the pathogenesis of systemic lupus erythematosus. This study evaluated the occurrence of ant...
BK virus (BKV) may cause nephropathy in renal transplant recipients receiving immunosuppressive therapy, resulting in renal dysfunction and, possibly graft loss. However, the positive and negative predictive values of BK viral load are still controversial. In this prospective, single-center study, BKV DNA was measured 1, 3 and 6 months after transplantation. The viral load in urine and plasma w...
PURPOSE OF REVIEW Polyomavirus nephropathy (PVN) mainly caused by BK virus (BKV) remains the most common productive viral infection of the kidney. Over the past decade, clinical interest often focused on BK viremia and viruria as the diagnostic mainstays of patient management. The purpose of this review is to discuss viral nephropathy in the context of BK viremia and viruria and new strategies ...
In addition to the previously characterized viruses BK and JC, three new human polyomaviruses (Pys) have been recently identified: KIV, WUV, and Merkel Cell Py (MCV). Using an ELISA employing recombinant VP1 capsid proteins, we have determined the seroprevalence of KIV, WUV, and MCV, along with BKV and JCV, and the monkey viruses SV40 and LPV. Soluble VP1 proteins were used to assess crossreact...
Objective: The objective is to establish the presence of JC and/or BK polyomavirus in HIV patients with symptoms of encephalitis and/or meningitis. Methodology: From September 2009 to December 2011, a prospective study was conducted. 34 HIV patients with symptoms consistent with encephalitis and/or meningitis were included. The work was conducted in 3 hospitals in the city of Monteria. Viral DN...
To assess the stability of polyomavirus antibodies in serial samples over time and the incidence and age-specific prevalence of polyomavirus infections, we established enzyme immunoassays (EIAs) using purified yeast-expressed virus-like particles (VLPs) containing the VP1 major capsid proteins of JC virus (JCV) and the AS and SB strains of BK virus (BKV). A random subsample of 150 Finnish women...
Background: The role of infectious agents in prostate cancer development has been considered for many years. Polyomaviruses are suspected to be related to human malignancies and they have been frequently detected from various human cancers. Aim: This study was performed to investigate presence of large t antigen encoded by Merkel Cell polyomavirus (MCV), JC polyomavirus (JCV), BK polyomavirus (...
Viral infections represent significant morbidity and mortality factors in kidney transplant recipients, with CMV, EBV, and BKV infections being most common. Desensitization (DES) with IVIg and rituximab with/without plasma exchange followed by kidney transplantation with alemtuzumab induction increased successful transplant rates in HLA-sensitized patients but may represent an increased risk fo...
