Brief Summary

The efficacy of anti-VEGF treatments such as Bevacizumab in cases of HHT can be considered because of the molecular mechanisms implied in angiogenesis and HHT, as well as the mechanisms of action of this type of treatment. Two articles that have recently reported spectacular improvement thanks to Bevacizumab in patients with HHT complicated with severe liver involvement and cardiac effects support us in this sense.

Up to now, the only treatment recommended in the severe hepatic forms of HHT is a liver transplant, the disadvantages of which are both multiple and well known: long waiting lists, surgical morbidity and mortality, immunosuppressive treatment for life. Furthermore, treatment with Bevacizumab is not a contraindication, should the drug be ineffective, for a subsequent liver transplant if necessary.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • General criteria:

    • Age ≥ 18 years and < 70 years
    • Subjects must have given their free and enlightened consent and have signed the consent form.
  • HHT related criteria

    • Patients monitored for clinically confirmed HHT disease.
    • Patients with severe liver involvement in relationship with the HHT disease
    • Patients with a high cardiac output on ultrasound.
  • Associated disease related criteria

    • Blood: neutrophil ≥ 1.0x109 / L and platelets ≥ 100x109 / L.
    • INR (International Normalized Ratio) ≤ 1.5 (except for patients on anticoagulants) and TCA ≤ 1.5 x upper limit of the standard laboratory
    • Renal function: creatinine ≤ 1.25 x upper limit of the standard laboratory. Patients who proteinuria to strip ≥ 2 + will have control of the Proteinuria of 24 hours to be ≤ 1g / 24 hours

Exclusion Criteria:

  • • General criteria
  • Women who are pregnant or liable to become pregnant in the course of the trial.
  • Patients who have reached their majority but who are protected by the terms of the law (French public health code).
