Home therapy of venous thrombosis with long-term LMWH versus usual care: patient satisfaction and post-thrombotic syndrome.

Purpose: Home-LITE compared long-term treatment at home with tinzaparin or usual care in terms of efficacy, safety, patients' treatment satisfaction, incidence of post-thrombotic syndrome, and associated venous leg ulcers.

Methods: This multicenter, randomized, controlled trial enrolled 480 patients with documented, acute, proximal deep vein thrombosis. Patients received tinzaparin 175 IU/kg subcutaneously once daily for 12 weeks, or tinzaparin for >or=5 days plus oral warfarin, commenced on day 1, international normalized ratio-adjusted, and continued for >or=12 weeks ("usual care").

Self-managed long-term low-molecular-weight heparin therapy: the balance of benefits and harms.

Purpose: A substantial clinical need exists for an alternate to vitamin K antagonists for treating deep vein thrombosis in many patients. Long-term low-molecular-weight heparin (LMWH), body-weight adjusted, avoids anticoagulant monitoring and may be associated with less bleeding. We evaluated the effectiveness and safety of long-term LMWH compared with vitamin K antagonist therapy in a broad spectrum of patients with proximal vein thrombosis.

Long-term low-molecular-weight heparin versus usual care in proximal-vein thrombosis patients with cancer.

Purpose: A substantial clinical need exists for an alternative to vitamin K antagonists for treating deep-vein thrombosis in cancer patients who are at high risk of both recurrent venous thromboembolism and bleeding. Low-molecular-weight heparin, body-weight adjusted, avoids anticoagulant monitoring and has been shown to be more effective than vitamin-K-antagonist therapy.

Subjects And Methods: Subjects were patients with cancer and acute symptomatic proximal-vein thrombosis.

Role of alpha/beta interferons in the attenuation and immunogenicity of recombinant bovine respiratory syncytial viruses lacking NS proteins.

Alpha/beta interferons (IFN-alpha/beta) are not only a powerful first line of defense against pathogens but also have potent immunomodulatory activities. Many viruses have developed mechanisms of subverting the IFN system to enhance their virulence. Previous studies have demonstrated that the nonstructural (NS) genes of bovine respiratory syncytial virus (BRSV) counteract the antiviral effects of IFN-alpha/beta.

Recognition of bovine respiratory syncytial virus proteins by bovine CD8+ T lymphocytes.

CD8+ T lymphocytes play a major role in the clearance of bovine respiratory syncytial virus (BRSV), an important respiratory pathogen of young calves that shares many of the epidemiological and pathological features of human respiratory syncytial virus (HRSV) in infants. Recombinant vaccinia virus (rVV) and recombinant fowlpox virus (rFPV), expressing individual BRSV proteins, were used to demonstrate that the F, N and M2 proteins were the major antigens recognized by bovine CD8+ T cells in major histocompatibility complex (MHC)-defined cattle. BRSV protein recognition by CD8+ T cells was analysed using cytotoxic T lymphocyte (CTL) assays or by the production of interferon-gamma (IFN-gamma) following restimulation with BRSV proteins.
