Conditions

Hereditary Hemorrhagic Telangiectasia, Rendu Osler Disease

Keywords

epistaxis, hemorrhage, anticoagulant therapy, antiplatelet therapy

Brief summary

The goal of this clinical trial is to evaluate in real life, in patients with Hereditary Hemorrhagic Telangiectasia (HHT), the tolerance of the strategy of use of anticoagulant and/or antiplatelet, by comparing a new exposure period (first trimester of treatment) to a period of reference non-exposure (last trimester before start of treatment).

Detailed description

Currently there are no recommendations on the use of anticoagulant and/or antiplatelet treatment in patients with Rendu-Osler Disease. The main question this study aims to answer is: • to better determine which anticoagulant and/or antiplatelet therapy are best tolerated or if they are equivalent in Rendu-Osler disease because this type of treatment is often used in urgent and/or vital situations. Participants will have a 2-year follow-up with biological monitoring of ferritin and hemoglobin level and ESS (Epistaxis Severity Score) and QoL-HHT (Quality of Life Hereditary Hemorrhagic Telangiectasia) questionnaires.

Interventions

OTHERmonitoring the use of anticoagulant and/or antiplatelet therapy in patients with osler rendering disease

Monitoring: * hemoglobin and ferritin levels * transfusion or intravenous iron * hospitalization for bleeding or thrombose * digestive bleeding and/or another haemorrhagic accident * severity of epistaxis * quality of life
