Inflammatory rhinitis is a side effect observed in patients treated with biotherapies in the context of chronic bowel disease (IBD) or spondylartrhopathy (SPA). This damage is still poorly described in the literature. It can occur in isolation or in association with a fold pustulose table, which differs from the classic fold pustulose described by Cribier et al in autoimmune diseases by the presence of staphylococcus aureus in the pustules. Some authors also describe associated paradoxical psoriasiform reactions or an impetigo. In our experience, this condition is more frequently found in patients treated for IBD or SPA and has a clinically characteristic fissure appearance. Thus, the semiology but also the epidemiology of this crusty rhinitis is still poorly described.~The objective of this study is to study the associated characteristics of crustal rhinitis in a cohort of patients treated with biotherapy for chronic inflammatory disease (IBD, SPA, psoriasis).~Patient recruitment will take place over a one-year period, in a multi-centre manner (Angers and Nantes University Hospital) with prospective data collection in the form of a questionnaire and clinical evaluation during a dermatology consultation planned in the traditional care pathway for the follow-up of patients with skin manifestations during biotherapy treatment.
