Human cytomegalovirus (CMV) infection represents a major threat for heart transplant recipients (HTXs). CMV-specific T cells effectively control virus infection, and thus, assessment of antiviral immune recovery may have clinical utility in identifying HTXs at risk of infection. In this study, 10 CMV-seropositive (R(+)) pretransplant patients and 48(More)
BACKGROUND AND OBJECTIVE Approximately 15% of patients with cancer will experience a thrombotic episode at some time. Some patients are at particularly high risk depending on the histology of the malignant disease. The aim of the study was to determine the actual prevalence of thrombotic episodes in oncohematologic patients. DESIGN AND METHODS We(More)
Intravenous ganciclovir is the standard treatment for cytomegalovirus disease in solid organ transplant recipients. Oral valganciclovir is a more convenient alternative. In a randomized, international trial, recipients with cytomegalovirus disease were treated with either 900 mg oral valganciclovir or 5 mg/kg i.v. ganciclovir twice daily for 21 days,(More)
BACKGROUND Cytomegalovirus (CMV) infection of solid organ transplant (SOT) recipients causes both ''direct'' and ''indirect'' effects including allograft rejection, decreased graft and patient survival, and predisposition to opportunistic infections and malignancies. Options for CMV prevention include pre-emptive therapy, whereby anti-CMV agents are(More)
Few studies have been performed on the prevalence of Torque Teno Virus (TTV) infection in liver transplant (LT) recipients. The aim of this study was to assess the prevalence, viremia and genogroup pattern of TTV among LT patients and to ascertain whether TTV causes liver damage in liver transplanted patients with biochemical and histological changes of(More)
Platelet-derived growth factor (PDGF) is thought to take part in the genesis of bone marrow fibrosis that can be found in patients with myeloproliferative diseases. We evaluated platelet mitogenic activity as the difference between serum and plasma activity in 8 patients with myeloproliferative disease. We observed a trend of lower values in 2 cases of(More)
BACKGROUND The ultimate goal of organ transplantation is the reestablishment of organ function and the restoration of a solid immunity to prevent the assault of potentially deadly pathogens. T cell immunity is crucial in controlling cytomegalovirus (CMV) infection. It is still unknown how preexisting antiviral T cell levels, prophylaxis, or preemptive(More)
Assessing cytomegalovirus (CMV)-specific cell-mediated immunity (CMI) represents an appealing strategy for identifying transplant recipients at risk of infection. In this study, we compared two gamma interferon-releasing assays (IGRAs), Quantiferon-CMV and CMV enzyme-linked immunosorbent spot (ELISPOT), to determine the ability of each test to predict(More)
ated with hypoxia, edema, or other unknown processes. However, the patient had no history of hypotensive episodes, hypoxemia, abnormal metabolic and toxic processes, and other infectious disease. In conclusion, IAAE with pandemic (H1N1) 2009 may be caused by direct viral infection of the CNS and, although its pathogenesis is not clear, physicians should(More)
BACKGROUND Neopterin is an intermediate in the pathway of pteridines released in vitro from non proliferating activated cells such as macrophages stimulated with interferons. Increased urinary excretion of neopterin has been described in conditions of cell-mediated immune activation and in neoplastic diseases, including haemopoietic tumours. METHODS We(More)
