[Baseline characterization of a cohort of colombian patients with chronic rhinosinusitis with nasal polyps].

OBJECTIVE

To present the baseline clinical and demographic characteristics of CRSwNP patients over the age of 18 enrolled in a Patient Support Program (PSP) prior to biologic treatment.

METHODS

Descriptive, cross-sectional study performed in a Colombian CRSwNP asthma PSP sponsored by Sanofi from Aug-2021 to Jul-2022. Data was collected from CRSwNP patients, prior to the start of Dupilumab treatment, who consented to the use of their data. The following information was reported: Age, reporting city, treating medical specialty, comorbidities, and persistence of treatment.

RESULTS

339 patients were included, 171 (50,4%) were women and 168 (49,6%) were men. The mean age at Dupilumab treatment initiation was 52,4 years. 62,8% began treatment during adulthood (26-59y), while 34.1% started at elderly (+60y) and 3.1% were young adults (18-25y). Most cases (29,7%) were included in Bogotá, followed by Antioquia (19%), Valle del Cauca (7,3%) and the remaining 44% nationwide. Comorbidities were present in 67,1% of the patients, with diagnosis of allergic rhinitis, atopic dermatitis, asthma, and other non-type 2 inflammatory diseases. Nasal surgical history was present in 89,6% of the patients, most of them with one to three previous surgeries. Continuous treatment was observed in 70,3% of patients for 6 to 12 months, in 21,3% for more than 12 months and in 8,4% for less than six months. The most frequently treating medical specialty was otorhinolaryngology (79,6%), followed by allergology (16%) and other medical professionals (4,4%).

CONCLUSIONS

There is concordance with the literature on a higher presentation of the disease in women than in men. There is a large proportion of patients with nasal surgical history and type 2 inflammatory comorbidities by the moment of biologic treatment initiation. The care and identification of CRSwNP colombian patients is mainly provided by otorhinolaryngologists, followed by allergologists.
