BACKGROUND Cytomegalovirus (CMV) infection in immunocompromised patients can lead to viremia associated with morbidity and mortality. Monitoring of viral loads in blood is critical for initiating and monitoring antiviral treatment. OBJECTIVES Validate quantitative real-time PCR assay targeting the US17 and UL54 regions of the CMV genome for automated DNA(More)
Respiratory viral infections are one of the leading causes of morbidity and mortality, particularly in children, the elderly and immunocompromised persons. Rapid identification of viral etiology is critical in ruling out non-viral infections, initiating antiviral treatment and limiting the spread of the infection. Multiplex assays of more than one viral(More)
Human cytomegalovirus (CMV) continues to be a significant cause of morbidity and mortality among transplant recipients. Molecular assays have been developed for the detection and quantification of CMV nucleic acid. In evaluating the clinical utility of these assays, correlations with clinical outcome are essential. The Amplicor CMV Monitor and NucliSens CMV(More)
Human metapneumovirus (hMPV) is a recently discovered paramyxovirus that is known to cause respiratory tract infections in children and immunocompromised individuals. Given the difficulties of identifying hMPV by conventional culture, molecular techniques could improve the detection of this virus in clinical specimens. In this study, we developed a(More)
Sodium heparin, an anticoagulant used widely for blood collection, has been known to inhibit DNA polymerase activity in polymerase chain reaction (PCR) assays. However, all cryopreserved plasma samples collected in the 1980s and early 1990s at the Multicenter AIDS Cohort Study were from heparin-treated blood, which poses a problem in quantifying the target(More)
BACKGROUND Respiratory tract infections are a major cause of outpatient visits, yet only a portion is tested to determine the etiologic organism. Multiplex reverse transcriptase polymerase chain reaction (MRT-PCR) assays for detection of multiple viruses are being used increasingly in clinical settings. METHODS During January-April 2012, outpatients with(More)
UNLABELLED Kaposi's sarcoma (KS) is an unusual neoplasia wherein the tumor consists primarily of endothelial cells infected with human herpesvirus 8 (HHV-8; Kaposi's sarcoma-associated herpesvirus) that are not fully transformed but are instead driven to excess proliferation by inflammatory and angiogenic factors. This oncogenic process has been postulated(More)
BACKGROUND While it is known that acute respiratory illness (ARI) is caused by an array of viruses, less is known about co-detections and the resultant comparative symptoms and illness burden. This study examined the co-detections, the distribution of viruses, symptoms, and illness burden associated with ARI between December 2012 and March 2013. METHODS(More)
Rapid, accurate, and cost-effective methods to identify the cause of respiratory tract infections are needed to maximize clinical benefit. Outpatients with acute respiratory illness were tested for influenza using a singleplex reverse transcriptase polymerase chain reaction (SRT-PCR) method. A multiplex RT-PCR (MRT-PCR) method tested for influenza and 17(More)
BACKGROUND Cytomegalovirus (CMV) infection can cause severe disease in immunocompromised individuals, with CMV pneumonia, most commonly seen in lung or bone marrow transplant recipients, carrying a particularly high fatality rate. Early and accurate diagnosis of CMV pneumonia is therefore critical. OBJECTIVES Current diagnostic tests for CMV pneumonia in(More)
