Primary human cytomegalovirus (HCMV) infection occurring in pregnant women within 3 months before (preconceptional) or within 4 weeks after (periconceptional) the last menstrual period represents an as-yet-undefined risk to the fetus. One (9.1%) of 11 newborns born to 12 women with preconceptional infection was subclinically infected (1 aborted fetus was(More)
The risk of vertical transmission of human cytomegalovirus (HCMV) was investigated in 14 women who had primary HCMV infection 2-18 weeks before their last menstrual period during 2001-2004. One (8.3%) of 12 newborns examined at birth was found to be subclinically infected. Preconceptional primary HCMV infection has a transmission rate that is significantly(More)
A quantitative PCR assay was used to quantitate human cytomegalovirus DNA in amniotic fluid of mothers of 21 fetuses with congenital infection. Seven fetuses presented ultrasound abnormalities or were born with symptoms, whereas 14 fetuses were subclinically infected. Although the median DNA level was higher in symptomatic fetuses, the difference was not(More)
During the winter-spring season 2006-2007, 38 influenza virus strains were identified in patients admitted to hospital with an acute respiratory tract infection. Infections were diagnosed in parallel by direct fluorescent antibody (DFA) staining using type-specific monoclonal antibodies and real-time reverse transcription (RT)-PCR targeting the gene M (nt(More)
Human cytomegalovirus (HCMV) was investigated in peripheral blood leukocytes (PBL) of 52 immunocompetent patients (40 pregnant women) with primary HCMV infection by quantitative determination of pp65 antigenemia, viremia, and leukoDNAemia. pp65 antigenemia was detected in 12 (57.1%) of 21, 4 (25%) of 16, and 0 of 10 patients examined 1, 2, and 3 months(More)
BACKGROUND Diagnosis of congenital human cytomegalovirus (HCMV) infection relies on virus isolation from urine collected in the first 3 weeks of life. However, very little is known about the presence, levels and duration of HCMV pp65 antigenemia, viremia and DNAemia in congenitally infected newborns. OBJECTIVES To investigate the diagnostic and prognostic(More)
BACKGROUND The burden of congenital human cytomegalovirus (HCMV) infection is well recognized. However, screening for maternal infection remains controversial in view of diagnostic challenges, counseling difficulties, and absence of medical treatment. OBJECTIVE To assess the role of prenatal diagnosis and counseling in the management of pregnancy(More)
BACKGROUND The T cell-mediated immune response to human cytomegalovirus (HCMV) after primary infection, as well as the determinants of intrauterine transmission, are poorly understood. METHODS Sequential peripheral blood leukocyte samples from 74 pregnant women and 29 nonpregnant individuals with primary infection were examined for HCMV-specific CD4+ T(More)
The pattern of HIV-1 reverse transcriptase and protease mutations conferring resistance to antiretroviral drugs was studied in five treatment-naive patients and five HIV-infected patients receiving HAART [two reverse transcriptase inhibitors + one protease inhibitor] for > or = 1 year. Direct sequencing was performed on plasma HIV RNA, HIV DNA from(More)
Human cytomegalovirus (HCMV) viremia in peripheral blood polymorphonuclear leukocytes (PMNLs) from 187 immunosuppressed patients (79 heart transplant recipients and 108 patients with acquired immunodeficiency syndrome [AIDS]) was investigated. Five mouse monoclonal antibodies (MAbs), one specifically reactive to HCMV immediate-early antigen (IEA) in PMNLs,(More)
