Current treatment of severe epistaxis in patients with hereditary hemorrhagic telangiectasia is not durable in reducing the frequency and severity of bleeds. Recent reports have demonstrated marked improvement of epistaxis with administration of either intravenous or topical bevacizumab. We present the long-term outcome of a patient who received repeated treatments of intravenous bevacizumab followed by maintenance intranasal bevacizumab. We demonstrate durable control of epistaxis with intranasal bevacizumab. This allows delivery of bevacizumab effectively, reduces cost, and obviates the risk of systemic adverse effects related to bevacizumab.

Unlabelled: Treatment of nosebleeds in Osler-Weber-Rendu disease (OWRD) is a therapeutic challenge. Intranasal anti-angiogenic sprays are a promising solution, requiring scientific validation, leading us to conduct the present study.
Objective: The main objective was to determine the minimum effective dose of bevacizumab by intranasal spray to treat epistaxis in OWRD: i.

Glioblastoma is one of the rapidly spreading cancers, with its potent malignancy often linked to pronounced angiogenesis within tumors. To mitigate this vascularization profile, bevacizumab (Avastin®), a monoclonal antibody, has been utilized for its antiangiogenic activity. However, its effectiveness is hindered by challenges in crossing the blood-brain barrier and the risk of off-target organ toxicity.

Previous studies have demonstrated that vascular endothelial growth factor (VEGF) is upregulated in patients with hereditary hemorrhagic telangiectasia (HHT). The use of Bevacizumab as an anti-angiogenic treatment agent seems promising. The purpose of the present study was to determine the efficacy and potential toxicity levels of bevacizumab on cell proliferation and VEGF concentrations in endothelial cells of HHT patients.

To evaluate the antitumor efficacy of bevacizumab-functionalized nanocapsules in a rat glioblastoma model after the pretreatment with nanocapsules functionalized with a peptide-specific to the epidermal growth factor receptor variant III. Nanocapsules were prepared, physicochemical characterized and intranasally administered to rats. Parameters such as tumor size, histopathological characteristics and infiltration of CD8 T lymphocytes were evaluated.

Vascular endothelial growth factor (VEGF) is a prime regulator of vascular permeability. Acute lung injury (ALI) is characterized by high-permeability pulmonary edema in addition to refractory hypoxemia and diffuse pulmonary infiltrates. In this study, we examined whether VEGF can be implicated as a pulmonary vascular permeability factor in sepsis-associated ALI.
