The goal of this observational study is to learn more about the real-world efficacy of biologics in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). All patients who are 18 years or older, who have CRSwNP and are eligible for reimbursement of a biological for the indication of CRSwNP can be included. The main question is the efficacy of biologics in real life after 24 weeks. The main focus are patient reported outcomes measured via several questionnaires and the nasal polyp score, scored with nasal endoscopy.
Chronic rhinosinusitis with nasal polyps (CRSwNP) has a prevalence of 5-10% in adults. It is often associated with other comorbidities, such as asthma (30-70% of CRSwNP patients) and aspirin exacerbated respiratory disease (AERD) (16% of CRSwNP patients) leading to a significant reduced quality of life (QoL). CRSwNP is diagnosed in patients with nasal polyps who have 2 or more of the following symptoms for more than 12 weeks: * Nasal blockage or nasal congestion * Runny nose or postnasal drip * Impaired sense of smell * Facial pain/pressure. Nasal rinses, intranasal or systemic corticosteroids, long-term antibiotics, and sinus surgery are the current standard of care. However, many patients fail to achieve complete therapeutic benefit and relapse after time, even after surgery. Moreover, oral corticosteroids are associated with significant side effects, and repeated sino-nasal surgery becomes progressively more complex with higher risk of complications. Patients with CRSwNP and most patients with asthma share a common type 2 inflammatory response, characterised by elevated levels of interleukin (IL)-4, IL-5, IL-13, eosinophils, T helper 2 (Th2)cells, and type 2 innate lymphoid cells. In addition, locally produced immunoglobulin E (IgE) is able to activate mast cells and induce local inflammation in CRSwNP. Biologicals are a specific kind of treatment with recombinant DNA-derived humanized monoclonal antibody that selectively binds specific targets in the inflammatory cascade which contributes to the pathophysiology of CRSwNP. Different biologicals have already been reimbursement for the treatment of Asthma for years, slowly these biologicals start to get their approval and reimbursement for CRSwNP. In Belgium (omalizumab (Xolair®), mepolizumab (Nucala®) and dupilumab (Dupixent ®) are reimbursed for patients with CRSwNP. Their efficacy has been demonstrated through large double-blind placebo-controlled clinical studies. However, until now only very limited reports on real-world data regarding this therapy have been published. This real-world data is important because it enables us to go beyond data gathered throughout a traditional randomised controlled trial (RCT). Traditional RCTs gather data from a controlled sample population with limited comorbidities and concomitant medications, who are likely to be compliant with the study requirements, whereas in real life patients might have poorer performance status and compliance and consist of a higher proportion of elderly patients. Therefore, this real-world data study aims to investigate how clinical outcomes of biologic therapy in real-world application (real-world efficacy) corresponds to outcomes in clinical trials (efficacy) and to look into factors that might explain an efficacy gap.

RECRUITINGTo evaluate the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the nasal congestion score (NCS).
Nasal congestion is scored from 0 ("No symptoms") to 3 ("Severe symptoms"). Higher scores denote greater symptom severity. Changes from baseline in NCS will be measured at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab).
Time frame: From enrollment until 3 years of treatment
To evaluate the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the nasal polyp score (NPS).
The total nasal polyp score (NPS) is an endoscopic nasal polyp scoring system to quantify nasal polyps with endoscopy. The higher the score, the more polyps are present in the nose. A unilateral score from 0 (absence of polyps) to 4 is given. The total nasal polyp score is the sum of the scores for both nostrils, thus ranging from 0 to 8, and is based on the continuous extension of nasal polyps beyond clear landmarks such as the upper and lower borders of the middle and inferior turbinate. This implies that a score can only be attributed if the criteria of the lower scores are met. E.g. a unilateral score of 3 cannot be given without nasal polyps also meeting the criteria for a score of 2, and similarly, a score of 4 cannot be given without having a score of 3. Changes from baseline in NPS will be measured at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological.
Time frame: From enrollment until 3 years of treatment
To evaluate the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the Visual analogue scale (VAS).
The rhinosinusitis severity VAS is used to evaluate the overall severity of the rhinosinusitis. It is a recommended scale to determine the patient's disease severity and to guide the treatment for CRS. The participant is asked to answer the following question: "How troublesome are your symptoms of your rhinosinusitis" on a 10-cm VAS from 0 ('not troublesome') to 10 ('worst thinkable troublesome'). Based on their score on the VAS, the severity of rhinosinusitis can be divided into 3 categories as follows: * Mild = VAS 0 to 3 * Moderate = VAS \>3 to 7 * Severe = VAS \>7 to 10 In this study, changes from baseline in VAS-scores at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab) will be measured.
Time frame: From enrollment until 3 years of treatment
To evaluate the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the Sino-Nasal Outcome Test-22 items (SNOT-22).
The SNOT-22 is a questionnaire designed to assess the impact of chronic rhinosinusitis on the patients' QoL. It has 22 items covering symptoms, social/emotional impact, productivity, and sleep consequences of CRS. Each item is rated on a 6-point Likert scale response option, ranging from 0 ('No problem') to 5 ('Problem as bad as it can be'). A global score ranging from 0 to 110 is calculated by summing the responses to all items; higher score indicates greater rhinosinusitis-related health burden. This study investigates changes from baseline in SNOT-22 at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab).
Time frame: From enrollment until 3 years of treatment
To compare the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the asthma control questionnaires 5-item version(ACQ-5).
The ACQ-5 was designed to measure both the adequacy of asthma control and change in asthma control. The participants are asked to recall how their asthma has been during the previous week and to respond to 5 questions on a 7-point scale (0 = no impairment, 6 = maximum impairment). A global score is calculated as follows: the questions are equally weighted, and the ACQ-5 score is the mean of the 5 questions and, therefore, falls between 0 (totally controlled) and 6 (severely uncontrolled). A higher score indicates lower asthma control. This study evaluates changes from baseline in ACQ-5 at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab).
Time frame: From enrollment until 3 years of treatment
To compare the effect of biologicals (omalizumab, mepolizumab and dupilumab) on the asthma quality of life questionnaire (AQLQ).
The AQLQ is comprised of 32 items, each rated on a 7-point Likert scale from 1 to 7. A higher score indicates better quality of life. This study evaluates changes from baseline in AQLQ at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab).
Time frame: From enrollment until 3 years of treatment
To compare the effect of omalizumab, mepolizumab and dupilumab on the sense of smell with the short questionnaire of olfactory disorders: negative statements (sQOD-NS).
sQOD-NS patient-reported outcome questionnaire includes social, eating, annoyance, and anxiety questions. Items are rated on a scale of 0-3, with higher scores reflecting the better olfactory-specific quality of life (QOL). The total score ranges from 0 (severe impact on QoL) to 21 (no impact on QoL). This study evaluates changes from baseline in sQOD-NS at 1, 3 and 6 months and 1, 1.5, 2 and 3 years for every biological (mepolizumab, omalizumab and dupilumab).
Time frame: From enrollment until 3 years of treatment
