Can patient-reported outcomes and inflammatory markers define endotype 2 in chronic rhinosinusitis without nasal polyps?
Background - Chronic rhinosinusitis (CRS) is a heterogeneous disease at the clinical phenotype level (without nasal polyp [CRSsNP] vs with nasal polyp [CRSwNP]) and at the underlying inflammatory endotype level (type 2 vs non-type 2). Whether the endotype is associated with clinical presentation in...

| Summary: | Background - Chronic rhinosinusitis (CRS) is a heterogeneous disease at the clinical phenotype level (without nasal polyp [CRSsNP] vs with nasal polyp [CRSwNP]) and at the underlying inflammatory endotype level (type 2 vs non-type 2). Whether the endotype is associated with clinical presentation in patients with CRSsNP has yet to be explored in detail. - Objective - To identify associations between endotypes and their clinical significance in patients with CRSsNP based on tissue interleukin-5 levels. - Methods - A total of 104 patients with CRSsNP who underwent functional endoscopic sinus surgery between 2013 and 2017 were endotyped. We collected immunologic and clinical parameters and evaluated whether there were associations between the endotype and clinical features using Visual Analog Scale (VAS), Sino-Nasal Outcome Test—22 (SNOT-22), Sniffin’ Sticks test, Lund-Mackay CT score, and nasal endoscopy. - Results - Mean tissue interleukin-5 levels were used to identify type 2 inflammation (non-type 2: 3.37 vs type 2: 191.98 pg/g tissue; P < .001). There were no significant clinical differences measured by patient-reported outcome measures between patients with type 2 CRSsNP and those with non-type 2 CRSsNP preoperatively. Type 2 and non-type 2 CRSsNP did not differentiate in CT score, Sniffin’ Sticks test, and nasal endoscopy. Postoperative SNOT-22 and VAS scores correlated well with each other (r = 0.75; P < .01). Postoperative VAS scores were in both groups significantly lower than before the operation (type 2: 5.07 vs 2.99; P < .01; non-type 2: 5.74 vs 3.22; P < .01), but not associated to the inflammatory subtype. - Conclusion - The type of inflammation does not affect the symptoms, the computed tomography scan, or the postoperative results in CRSsNP in contrast to former findings in CRSwNP. - Trial Registration - Belgian registration number (B.U.N.) No. B6702020000097. |
