HIV type 1 (HIV-1) not only directly kills infected CD4(+) T cells but also induces immunosuppression of uninfected T cells. Two immunosuppressive proteins, interferon alpha (IFNalpha) and extracellular Tat, mediate this process because specific antibodies against these proteins prevent generation of suppressor cells in HIV-1-infected peripheral blood(More)
Congenital afibrinogenemia is a rare auto-somal recessive disorder characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and plate-let fibrinogen. Although several mutations in the fibrinogen genes associated with dysfibrinogenemia and hypofibrino-genemia have been described, the genetic defects(More)
Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by the complete absence of plasma fibrinogen and by a bleeding tendency ranging from mild to moderately severe. Beside a deletion of the almost entire Aalpha-chain gene, only 2 missense mutations in the C-terminal domain of the Bbeta-chain have been very recently described as(More)
A recombinant fusion protein linking coagulation factor IX (FIX) with human albumin (rIX-FP) has been developed to facilitate hemophilia B treatment by less frequent FIX dosing. This first-in-human dose-escalation trial in 25 previously treated subjects with hemophilia B (FIX ≤ 2 IU/dL) examined the safety and pharmacokinetics of 25, 50, and 75 IU/kg(More)
In persons with hemophilia, life expectancy is now approaching that of the general male population, at least in countries that can afford regular replacement therapy with coagulation factor concentrates. The new challenges for comprehensive treatment centers are thus to provide optimal health care for this aging population of patients, who often present not(More)
Factor V (FV) deficiency is a rare bleeding disorder whose genetic basis has been described in a relatively small number of cases. Among a total of 12 genetic defects reported in severely or moderately severe deficient patients, 3 were missense mutations and in no case was the mechanism underlying the deficiency explored at the molecular level. In this(More)
Severe factor V (FV) deficiency is a rare bleeding disorder, whose genetic bases have been characterized only in a limited number of cases. We investigated 6 unrelated patients with extremely reduced plasma FV levels, associated with a bleeding tendency ranging from moderately severe to severe. Clinical manifestations were substantially concordant with the(More)
Melanocortins are proopiomelanocortin-derived peptides that include adrenocorticotropic hormone [ACTH (1-39)], alpha-melanocyte-stimulating hormone [alpha-MSH (1-13)], and related amino acid sequences. Melanocortin peptides have potent antiinflammatory/anticytokine activity. Because cytokines such as interleukin 1 (IL-1) and tumor necrosis factor (TNF) can(More)
Despite advances in the management of HIV infection with the introduction of combination antiretroviral therapy, it is well known that HIV can directly infect the central nervous system and, as a result of such infection, neuropsychological impairments can be manifested. In this study, we tried to determine whether seropositivity was associated with a poor(More)
BACKGROUND The high mutational heterogeneity of hemophilia A is a challenge for the provision of genetic services. We plan to identify the mutation in patients with hemophilia A in order to create a confidential national database of mutations for the optimization of genetic services in Italy. DESIGN AND METHODS The factor VIII gene (F8) was analyzed in(More)
