BACKGROUND Low levels of Cytomegalovirus (CMV) viral load are frequently detected following allogeneic stem cell transplantation (SCT) and CMV disease may still develop in some allogeneic SCT patients who have negative pp65-antigenemia (pp65-Ag) or undetectable DNA. Pp65Ag is a sensitive method to diagnose CMV infection. Quantitative CMV-DNA PCR assay in plasma has been proposed to monitor CMV ...

BACKGROUND Very low birth weight (VLBW) and premature infants are at risk for developing postnatal cytomegalovirus (CMV) disease, including CMV-related sepsis-like syndrome (CMV-SLS) for which estimates [corrected] in the United States are lacking. METHODS We performed a systematic review and meta-analysis to estimate the pooled proportions (and 95% confidence intervals) of VLBW and premature...

Background. The duration of anti-CMV after LT varies widely among transplant centers. Because CMV is associated with poor outcome, some centers have extended prophylaxis to reduce the rates of CMV disease. We aimed to assess the epidemiology and outcome of CMV infection in high-risk LT recipients receiving extended (and for some, lifelong) prophylaxis. Methods. This is a retrospective review of...

Late occurrence of cytomegalovirus (CMV) disease after day 100 after bone marrow transplantation has become an increasing problem; whether a quantitative measurement of CMV DNA in plasma by polymerase chain reaction (P-PCR) could be predictive of such disease was investigated. In a prospective study, 117 subjects undergoing allogeneic marrow transplantation were followed for 120 days with weekl...

The mechanisms of inhibition of cytomegalovirus (CMV) infection by human CD13 (aminopeptidase N)-specific antibodies were studied. These antibodies protect CD13-negative and -positive cells from CMV infection only if incubated with the virus inoculum, suggesting they bind to CMV virions. The association of a CD13-like molecule with virions was further supported by the transfer of CD13 immunorea...

Human cytomegalovirus (CMV) continues to be a major threat against solid-organ transplant recipients despite significant advancements in its prophylaxis and therapy. Primary CMV infection or reactivation of latent CMV in the transplant recipients may cause CMV diseases such as flu-like viral syndrome and tissue-invasive CMV disease. In addition, CMV infection in the recipients is associated wit...

BACKGROUND AND OBJECTIVES Cytomegalovirus (CMV) disease remains an important complication of allogeneic stem cell transplantation (SCT). We studied viral load kinetics and correlated the viral load and other transplant factors with the development of CMV disease. DESIGN AND METHODS We studied 162 consecutive patients who were CMV seropositive or had CMV seropositive donors. Quantification of ...

OBJECTIVES Restoration of Cytomegalovirus-specific-CD4 T cell (CMV-Sp-CD4) responses partly accounts for the reduction of CMV-disease with antiretroviral-therapy (ART), but CMV-Sp-CD4 may also drive immune activation and immunosenescence. This study characterized the dynamics of CMV-Sp-CD4 after ART initiation and explored associations with CD4 T cell recovery as well as frequency of naïve CD4 ...

Ganciclovir effectively prevents cytomegalovirus (CMV) disease in the first 100 days after allogeneic hematopoietic stem cell transplantation (HSCT), but late-onset CMV disease is increasingly observed. We designed a prospective cohort study to define the incidence and risk factors for late CMV infection in patients who undergo HSCT. CMV-seropositive patients were studied prospectively for CMV ...

OBJECTIVES To establish a sensitive and specific real-time PCR for quantitation of cytomegalovirus (CMV) DNA in clinical specimens. SUBJECTS AND METHODS In a prospective study, CMV DNA was quantified in blood samples of 255 kidney recipients with and without CMV-related symptoms between the years 2000 and 2005 in Kuwait. In a selected group of patients, the effect of anti-CMV chemotherapy was...
