Abstract
OBJECTIVES: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a highly prevalent and challenging disease to manage. Several systematic reviews (SRs) have been carried out to evaluate the efficacy and safety of biologic therapies. We aimed to evaluate the current and available evidence of the biologics in treating CRSwNP. DATA SOURCE: Systematic Review of three electronic databases. REVIEW METHODS: Following the PRISMA Statement, the authors explored three main databases through February 2020 for pertinent SRs and meta-analyses (MAs) as well as experimental and observational studies. A Measurement Tool to Assess Systematic Reviews Version-2 (AMSTAR-2), was employed to evaluate the quality of methodology of SRs and MAs. RESULTS: A Total of five SRs were included in this overview. The AMSTAR-2 final summary was moderate to critically low. Although conflicting findings were reported, anti-immunoglobulin E (Anti-IgE) and anti-interleukin-4 (Anti-IL-4) were superior to placebo for improving total nasal polyp (NP) score, particularly in patients with asthma. Findings of the included reviews revealed that both sinus opacification and the Lund-Mackay (LMK) total scores significantly improved after biologics use. Subjective quality-of-life (QoL) assessment provided by general and specific questionnaires illustrated favorable results of biologics for CRSwNP, whereas no significant adverse events were reported. CONCLUSION: The current findings support the use of biologics for CRSwNP patients. However, the evidence for their use in such patients should be cautiously adopted because of the questionable evidence.
