Results of personalized biological therapy in patients with chronic rhinosinusitis with nasal polyps and severe uncontrolled bronchial asthma – real-life study

Le résumé fourni par la source

Introduction: Severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) are frequently comorbid diseases caused by type 2 inflammation. The complete etiology of these forms still remains unexplained, which makes causal and fully effective therapeutic management impossible. New therapeutic options using the knowledge of Th2 inflammatory endotype are based on anti-IL5 (mepolizumab, reslizumab), anti-IL5R (benralizumab), anti-IgE (omalizumab), and anti-IL4/IL13 (dupilumab) monoclonal antibodies. Recently, biological therapy has provided a new personalized therapeutic option for patients with CRSw NP.Aim: The aim of the study was to evaluate the efficacy of mepolizumab, benralizumab, omalizumab, and dupilumab in the reduction of rhinological symptoms in severe asthmatic patients with chronic rhinosinusitis with nasal polyps.Materials and methods: In 32 (9 male, 18%) patients with CRSwNP and severe bronchial asthma treated with biologics - mepolizumab (19, 59%), omalizumab (5, 15%), benralizumab (6, 19%), and dupilumab (2, 6%) for 6 months, a subjective evaluation of rhinologic symptoms was conducted (TNSS, SNOT, smell evaluation).Results: In all analyzed groups, 6-month treatment with mepolizumab, omalizumab, and benralizumab resulted in significant improvement in rhinitis symptoms assessed by TNSS and SNOT scales as well as in the sense of smell. Due to the small group of patients treated with dupilumab, statistical analysis in this group was not performed.Conclusions: Our real-life observation confirmed that biological therapy based on phenotyping enables achieving optimal therapeutic effects for patients with CRSwNP and severe bronchial asthma. Biological therapy should be conducted through a collaborative and multidisciplinary approach.
