Filter by:Bevacizumab is widely prescribed for the treatment of severe bleeding related to epistaxis or gastrointestinal bleeding in HHT. We studied the efficacy of bevacizumab on severe bleeding in HHT patients in a randomized study recently published (NCT03227263, J Int Med 2023). In this study, 24 patients were included, 12 patients received bevacizumab and 12 patients received placebo. The duration of patient participation was 6 months, including the 2.5-month treatment period and 3.5 month follow-up after treatment. We describe the evolution of the number of RBC transfused in HHT patients who received bevacizumab during the year after the end of the study.
A long-term follow-up cohort study of patients that were assigned in two previous studies to compare the clinical results of sclerotherapy of telangiectasias and reticular veins of lower limbs using 0.2% polidocanol diluted in 70% hypertonic glucose (PDHG) vs 75% hypertonic glucose (HG) alone. All women, previously treated as aforementioned, were invited to be reevaluated regarding late maintenance and pigmentation over two years of follow-up. No new treatments were applied to the cohort.
The goal of this interventional study is to determine the incidence of depression, anxiety, sleep disturbances and resilience in a sample of subjects affected by Hereditary Hemorrhagic Telangiectasia. The study is declined through the evaluation of some outcome parameters at the time of enrollment (T0), during the counseling intervention (T1 and T2) and at the end (T3) of the subjects who will have carried out an individual counseling intervention.
Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu syndrome patients are carriers of a heterozygous mutation of the activin receptor-like kinase 1 (ACVRL1), Endoglin (ENG) or Mothers against decapentaplegic homolog 4 (SMAD4) gene. HHT involves the Bone Morphogenetic Protein 9 (BMP9)/Activin receptor-Like Kinase 1 (ALK1)-endoglin signalling pathway. BMP9 is a growth factor that binds to ALK1 receptor and to endoglin its co-receptors and physiologically activates Smad signaling pathway. Endothelial cells in HHT patients display half expression of functional ALK1 receptors or endoglin co-receptors or of the transcription factor SMAD4, which should lead to effects on the functions of these cells. The identification of differences in gene expression between endothelial cells from HHT patients and healthy donors will allow the identification of new functions or new target pathways for therapy. Circulating endothelial cells are rare in the bloodstream in adults, but are present in greater quantities in cord blood.
Ataxia-telangiectasia (A-T) is a multisystem auto-somal recessive disorder linked to the A-T mutated gene (ATM) on chromosome 11q22-23, and characterized by progressive neural degeneration, immunodeficiency, and progressive ocular motor dysfunction. In previous studies, the quantitative description of the ocular motor deficits from clinical examination was limited to various defects in saccade and gaze control, dysmetric saccades, impairments of smooth pursuit, gaze holding, convergence, vestibular and optokinetic nystagmus slow phases, and cancellation of the vestibulo-ocular reflex. The aim of our research is to add existing findings with quantitative description of oculomotor patterns in A-T patients using videooculography (VOG).
Ataxia Telangiectasia (A-T) is an inherited disorder characterised by cerebellar neurodegeneration, immunodeficiency and respiratory disease. People with A-T have abnormal DNA repair and consequently have an increased risk of cancer. Despite this, current guidelines for management of children and young people with A-T do not include cancer surveillance. Improvements in MRI technology have allowed whole-body MRI (WB-MRI) scanning with relatively short acquisition times. Currently, WB-MRI protocols are used for diagnosing and monitoring some primary and secondary cancers, including cancer surveillance in people with the Li-Fraumeni syndrome, which is another genetic cancer predisposition syndrome. Therefore, the research team believe that whole-body MRI provides a safe method for cancer surveillance in children and young people with A-T. However, the investigators do not know whether cancer surveillance in children and young people with A-T using whole-body MRI is feasible and desirable. The research team proposes a feasibility study of MRI-based cancer surveillance with qualitative evaluation of participant experience with the primary aim to establish: - feasibility of whole-body MRI for cancer surveillance in children and young people with A-T - views of, and psychological impact on, participants and families / carers participating in whole-body MRI for cancer surveillance. - feasibility of conducting a formal screening trial in terms of statistical design, sample size, screening interval, comparator arms and international collaboration Completion of this study will provide us with evidence of technical feasibility, very strong evidence of child / family views, a viable formal screening trial design and an engaged international research community, allowing us to proceed to a formal trial establishing the efficacy of a cancer surveillance programme for children and young people with A-T.
This single-center, prospective, open-label, quasi-experimental, intra-individual comparative study will include a consecutive cohort of 21 patients with diffuse or limited, minimally active scleroderma with 3 to 30 years of evolution. Patients will have 4 sessions of pulsed dye laser 595 nm spaced 8 weeks apart. The final quadruple evaluation by several evaluators will be 2 months after the last session, on the following criteria: evolution of the number of telangiectasia; subjective improvement score (LINKERT scale); impact on quality of life (SKINDEX score); visual analog pain scale (VAS); adverse events (AEs), including discontinuation of treatment due to post-session purpura (AT-PPS); patient satisfaction (yes or no).
1. Facial telangiectasia is one of the common skin vascular lesions characterized by dilated cutaneous vasculatures in the skin surface or mucous membranes. Lesions are generally sensitive to exposure of cold, heat and sun. Those distinct small dilated blood vessels are cosmetically disfiguring for patients which require an effective solution. The traditional management options for facial telangiectasia include cryotherapy, CO2 laser, topical agent, oral estrogens, electrosurgery, and radioactive treatment. However, inadequate outcomes and severe adversaries are the major concerns to patients and physicians. 2. Pulsed dye laser (PDL) is effective for vasodilatory diseases, especially for the superficial to middle layers of the dermis. The intense pulsed light source is an alternative or supplement to the already existing laser devices that are part of the laser surgeon's repertoire. The broad wavelength spectrum and variable pulse duration allow greater penetration depths to be reached without damaging surrounding tissue and thus enhance the versatility of this system. 3. This study aims to compare the clearance efficacy of facial telangiectasia using PDL (595nm) with IPL configured by various wavelength bands, including M22 vascular filter (530-650nm and 900-1200nm), M22 560 (560-1200nm), M22 590 (590-1200nm) .
This is a multi-center, open-label, 6-month study to evaluate the safety of bilateral CNTF implants in participants with Macular Telangiectasia Type 2.
