BACKGROUND Cytomegalovirus infection and disease is associated with poor prognosis and steroid refractoriness in inflammatory bowel disease patients. The unfavourable effect of steroids and immunosuppressive therapy on CMV infection is well known but few data are available concerning anti-TNFalpha therapy (Infliximab). Aim of the study was to evaluate the(More)
Kaposis's sarcoma associated herpesvirus (KSHV) has been reported to infect, among others, monocytes and dendritic cells DCs impairing their function. However, the underlying mechanisms remain not completely elucidated yet. Here we show that DC exposure to active or UV-inactivated KSHV resulted in STAT3 phosphorylation. This effect, partially dependent on(More)
BACKGROUND Changes of HHV-8 antibody reactivity and intermittent detection of HHV-8 DNA have been observed in subjects with Kaposis's Sarcoma and/or HIV infection. Little is known about the longitudinal dynamics of HHV-8 DNA and antibody response in allografted stem cell transplant (SCT) patients without Kaposis's Sarcoma. OBJECTIVES To report the natural(More)
To determine the prevalence of human herpesvirus 8 (HHV-8) infection, the rate of HHV-8 seroconversion, and the presence of serum HHV-8 DNA after bone marrow transplantation (BMT), we evaluated sera from 187 Italian BMT donor-recipient pairs. Antibodies to lytic and latent HHV-8 antigens were detected by immunofluorescence. Sera of donor-recipient pairs who(More)
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(More)
We verified whether a clinical score system developed for renal transplant patients predicts the severity and outcome of cytomegalovirus interstitial pneumonia (CMV IP) in allogeneic bone marrow (BMT) recipients. The score system was retrospectively applied to 20 patients at the estimated date of onset of IP and 10-14 days later. Seven patients received(More)
Little is known about the incidence and clinical impact of cytomegalovirus (CMV) infection in patients with acute myeloid leukemia at the time of diagnosis and during chemotherapy. The aims of the present study were to assess prospectively the incidence of active CMV infection in 69 consecutive patients with acute myeloid leukemia and to describe the(More)
Aim of the study was to correlate the clinical outcome of eighteen patients who have undergone an allogeneic stem cell transplant (SCT) with the concentration in the peripheral blood (PB) of lymphocyte subpopulations evaluated at 1 year from transplant. The occurrence of acute GVHD and CMV infection correlated with the concentration of Tregs in the PB; CMV(More)
