[New manifestation of a type 2-inflammation in the upper respiratory tract with nasal polyposis under treatment with an asthma biologic].

Introduction: For 7 years we gained experience of how asthma and chronic rhinosinusitis with nasal polyposis respond to biologics. In contrast, it is much less known, how ASA/NSAID intolerance (Widal's disease) behaves under biologicals. We therefore describe the case of a patient with both clinical conditions who reacted with a severe intolerance reaction under perioperative metamizole administration.
