Background: Primary infection with BK virus (BKV) is occurred during childhood and usually asymptomatic, but after initial infection, BKV may persist lifelong in the kidney and genitourinary tract. Reactivation may occur in individuals with compromised immunity such as renal transplant recipients. Due to the role of BKV in BK virus-associated nephropathy (BKVAN) and po...
BACKGROUND AND OBJECTIVES The objective was to study the long-term impact of transient versus persistent BK viremia on kidney transplant outcomes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In total, 609 recipients who underwent kidney transplant from 2007 to 2011 were screened at months 1-12 for the occurrence of polyomavirus BK viremia; 130 patients (21.7%) developed BK viremia during th...
Background/Aim. Quantitative hepatitis B surface antigen (qHBsAg) has become increasingly widespread in the last few years both diagnostic and therapeutic protocols for chronic HBV infection. Numerous studies have proposed it as a surrogate marker covalently closed circular DNA (cccDNA). Our study aimed to examine correlation between qHBsAg viremia untreated patients. Methods. The included 112 ...
There are limited data regarding intermediate-term outcomes in patients with persistent BK viremia. Other viral infections have been implicated in the development of allosensitization through heterologous immunity, but the relationship between BK viremia and donor-specific antibodies (DSAs) is unexplored. In 2008, we initiated routine post-transplant BK viremia and DSA screening at our center; ...
We describe the magnitude and kinetics of plasma viremia and nonstructural protein 1 (sNS1) levels in sequential samples from 167 children with acute dengue, enrolled early in a community study in Vietnam. All children recovered fully, and only 5 required hospitalization. Among those with dengue virus type 1 (DENV-1), plasma viremia was significantly greater in primary (49) than secondary (44) ...
Changes in the BK virus archetypal noncoding control region (NCCR) have been associated with BK-virus-associated nephropathy (BKVAN). Whether sustained viremia, a surrogate for BKVAN, is associated with significant changes in the BK-NCCR is unknown. We performed PCR amplification and sequencing of (1) stored urine and (2) plasma samples from the time of peak viremia from 11 patients with sustai...
Human herpesvirus 6 (HHV-6) infection was studied in 82 bone marrow transplant (BMT) recipients (72 allogeneic, 10 autologous). All recipients and 30 donors were seropositive for HHV-6 antibody at the time of bone marrow transplantation. Thirty-one recipients (37.8%) had HHV-6 viremia 2-4 weeks after transplantation. The incidence of HHV-6 viremia was significantly higher among allogeneic BMT r...
Infectious complications, particularly viral infections, remain a significant cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (alloHCT). Only a handful of studies in children have analyzed the risks for and impact of viremia on alloHCT-related outcomes. We conducted a retrospective study of 140 pediatric patients undergoing alloHCT to investigate the inciden...
Background: : With HAART being used extensively ,transiently detectable viremia, usually 50400 copies/ml, has been found to be a common phenomenon, occurring in about one-quarter of HIV/AIDS patients who had achieved viral suppression below the limits of quantification while remaining on the same antiretroviral regimen. Though measurable viremia may be a harbinger of drug resistance and treatme...
