BACKGROUND: Hereditary haemorrhagic telangiectasia (HHT) remains a difficult disease for the ENT specialist to manage. Affected patients often report recurrent epistaxis as the most debilitating symptom. The pathogenesis of the disease is due to genetic mutations affecting angiogenesis. For this reason, the anti-angiogenic therapy bevacizumab has gained popularity in the local treatment of epistaxis in patients with HHT.
OBJECTIVE: A systematic review of the efficacy of bevacizumab in local treatment of epistaxis in patients with HHT based on epistaxis duration, frequency, severity and impact on quality of life.
METHODS: A systematic search was performed using the PubMed, MEDLINE and EMBASE databases. The Preferred Items for Systematic Reviews and Meta-Analyses guidelines were followed. Studies that measured the efficacy of intranasal bevacizumab treatment of epistaxis in patients with HHT were included for qualitative analysis.
RESULTS: Thirteen studies (four randomised controlled trials, three prospective studies, three retrospective studies, one case series and two case reports) with a total of 357 patients were included. Local administration (either by submucosal injection or topically) did not have a significant impact on epistaxis duration, frequency, severity or quality of life compared to placebo or other local treatments.
CONCLUSIONS: The available evidence suggests that intranasal bevacizumab treatment does not have a significant effect on epistaxis in patients with HHT. There are several limitations that require further investigation to confidently rule out local bevacizumab as an effective therapy in HHT related epistaxis.
