[Tolerance of bevacizumab therapy in systemic sclerosis-associated pulmonary arterial hypertension: A case report]. / Tolérance du bévacizumab au cours de l'hypertension artérielle pulmonaire associée à la sclérodermie systémique : à propos d'une observation.

ABSTRACT

INTRODUCTION: No data is available regarding the safety of bevacizumab, an anti-vascular endothelial growth factor-A (VEGF-A) antibody, in patients with pulmonary arterial hypertension (PAH), a condition in which VEGF seems to play a significant and probably protective role. CASE REPORT We report a patient with a history of systemic sclerosis-associated PAH, stable under bosentan therapy. She was diagnosed with metastatic cervical epidermoid carcinoma and treated by two successive cytotoxic chemotherapy regimens. As these treatments failed to control disease progression, she was started on anti-angiogenic therapy 3 infusions of bevacizumab 15 mg/kg were administered. Over the course of this treatment, no change in the clinical status or echocardiography parameters was noted. CONCLUSION: This observation suggests that, under careful clinical and echocardiographic follow-up, bevacizumab therapy can be well tolerated in case of stable and moderate PAH. Decision of treatment should be taken cautiously, as the possibility of PAH worsening is not excluded.
