Therapie der chronischen Rhinosinusitis mit Polyposis nasi (CRScNP) mit monoklonalen Antikörpern (Biologika): S2k-Leitlinie der Deutschen Gesellschaft für Hals-Nasen-Ohren-Heilkunde, Kopf- und Hals-Chirurgie (DGHNO-KHC) und der Deutschen Gesellschaft für Allgemeinmedizin und Familienmedizin (DEGAM)

Monoclonal antibodies (so-called biologics) can be prescribed for chronic rhinosinusitis with nasal polyps (CRSwNP) within the scope of their market authorization. However, their prescription is limited to severe CRSwNP without disease control, whereby certain requirements must be met. Dupilumab, omalizumab, and mepolizumab have currently gained market authorization, with adequate evidence for their efficacy and safety available in the literature. It can be assumed that other biologics will be approved for this indication in the future. The severity of disease and the efficacy of treatment should be assessed objectively and subjectively before treatment initiation and after an appropriate duration, respectively. The documentation sheet proposed in this guideline chapter can be used for the assessments. In the presence of relative contraindications, a treatment should only be initiated after differentiated consideration by an experienced physician in the sense of a case-by-case decision. In summary, this guideline chapter aims to contribute to high-quality care of adult patients with these therapies in view of the increasing evidence for treatment with these substances and the increasing number of market authorizations of different biologics.
