RESUMO
Chronic rhinosinusitis with nasal polyps (CRSwNP) associated with type 2 inflammation and non-steroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) can be difficult to control with standard medical therapy and sinus surgery. In this group, biologicals are potentially promising treatment options. The phase III clinical trials for omalizumab, dupilumab, mepolizumab and benralizumab in CRSwNP have demonstrated favourable outcomes. Moving forward, direct comparisons among biologicals, refining patient selection criteria for specific biologicals, determining optimal treatment duration and monitoring long-term outcomes are areas of emerging interest. This review summarizes the clinical evidence from the recent 2 years on the role of biologicals in severe CRSwNP and N-ERD, and proposes an approach towards decision-making in their use.
