Updates on current evidence for biologies in chronic rhinosinusitis

摘要

Purpose of review The purpose of this review is to present the most important recent developments concerning biologies as a therapeutic option for chronic rhinosinusitis (CRS). Recent findings mAb anti-IL-4 receptor a (Dupilumab) was recently approved by Food and Drug Administration (FDA) for patients with CRSwNP and four other biologies are under investigation, with promising preliminary results. Summary CRS is a disease associated with a significant symptom burden and high-indirect costs. Despite recent advances in combined approaches, persistent symptoms or recurrences are not uncommon. Monoclonal antibodies, used mainly to treat asthma, have recently been shown to have a positive impact on controlling the symptoms of CRS and reducing the need for endoscopic sinus surgery. Dupilumab, mepolizumab, reslizumab, benralizumab and omalizumab are discussed and their mechanism of action, risk and current evidence on efficacy are presented. Preliminary studies show encouraging results with relatively few side effects. Once the high cost of such therapies is addressed, they could prove an important adjuvant therapy for patients with CRS. Large-scale clinical trials designed to evaluate them are called for.
