Chromosomally integrated human herpesvirus 6 (ciHHV-6) is a condition in which the complete HHV-6 genome is integrated into the host germ line genome and is vertically transmitted in a Mendelian manner. The condition is found in less than 1% of controls in the USA and UK, but has been found at a somewhat higher prevalence in transplant recipients and other(More)
OBJECTIVE To study the role of cytomegalovirus (CMV) in the etiology of rheumatoid arthritis (RA). METHODS Polymerase chain reaction (PCR), immunoperoxidase staining for CMV specific antigens, virus isolation and antibody assays were applied to study samples from patients with RA of less than one year's duration. RESULTS By PCR, CMV DNA was detected in(More)
Human herpesvirus-6 (HHV-6), which comprises of HHV-6A and HHV-6B, is a common infection after solid organ transplantation. The rate of HHV-6 reactivation is high, although clinical disease is not common. Only 1% of transplant recipients will develop clinical illness associated with HHV-6 infection, and most are ascribable to HHV-6B. Fever,(More)
BACKGROUND Human herpesvirus (HHV)-6 has recently been reported in liver transplant patients. It infects and causes dysfunction in hepatic transplants, which provides serious differential diagnostic problems between allograft rejection and viral infection. The diagnosis of posttransplantation HHV-6 infection is usually based on serology or on polymerase(More)
BACKGROUND Quantification of cytomegalovirus (CMV) load is central to the management of CMV infections in immunocompromised patients, but quantitative results currently differ significantly across methods and laboratories. METHODS The COBAS AmpliPrep/COBAS TaqMan CMV Test (CAP/CTM CMV test), developed using the first World Health Organization CMV standard(More)
Cardiac allograft vasculopathy is a major limiting factor of the long-term survival of heart transplant patients. An association of cytomegalovirus infection and cardiac allograft vasculopathy has been described. We analyzed 104 endomyocardial biopsy specimens obtained from 53 heart transplant recipients and correlated the histologic findings with 115(More)
BACKGROUND Cytomegalovirus (CMV) infection is suggested to be a risk factor for chronic rejection. We have recently shown that rat CMV (RCMV) increases the inflammatory response and accelerates chronic rejection in a model of rat kidney allograft. In this study, the early inflammatory response and time-related expression of intercellular adhesion molecule-1(More)
Immunodetection of Pneumocystis carinii, based on immunofluorescence and use of a monoclonal antibody specific for an antigen located within the cyst wall and detectable after trypsin digestion only, was compared with a methenamine silver stain in 553 bronchoalveolar lavage specimens from immunosuppressed patients. P. carinii was found by immunofluorescence(More)
Congenital nephrotic syndrome of the Finnish type (CNF) is an autosomal recessively inherited disease manifesting as massive proteinuria, edema and ascites in the neonatal period. The disease is believed to be limited to the kidneys and recurrences after renal transplantation have not been reported. At our center 29 transplantations have been performed on(More)
BACKGROUND Betaherpesviruses human herpesvirus-6 and -7 (HHV-6, HHV-7), which are closely related to cytomegalovirus (CMV), have been reported in transplant patients. In this retrospective study, we investigated the occurrence of HHV-6 and HHV-7 antigenemia in relation to symptomatic CMV infection after liver transplantation. METHODS Sample material from(More)
