Clinically, extranodal natural killer/T-cell lymphoma (ENKTL) patients frequently had a history of chronic rhinosinusitis (CRS) before onset, and the correlation between the two diseases has not been systematically reported at present. In this study, we applied the method-retrospective analysis-to explore the relationship between CRS and ENKTL. We collected clinical data and the length of CRS history before onset in 214 patients diagnosed with ENKTL and found that the length of CRS history was correlated with the stage of 182 ENKTL patients whose primary sites were upper aerodigestive tract (UAT) (  = 21.317, = 0.046, = 182); the Spearman correlation coefficient was 0.162 ( = 0.029). There was no significant difference in stage of the non-UAT-ENKTL patients ( = 18.910, = 0.091, = 32). The COX multivariate regression analysis showed that CRS history was an independent prognostic predictor for PFS of the UAT-ENKTL patients ( = 0.004), and patients without CRS had significantly better PFS than the more than 15 years CRS history group ( = 0.001). Our findings suggested that we should not ignore the existence of chronic inflammation of the nasal cavity in ENKTL patients. It is better to treat CRS as soon as possible in clinical practice to reduce the possibility of the occurrence or progression of UAT-ENKTL.

Background: Although randomized controlled trials (RCT) have demonstrated the efficacy of mepolizumab for asthma, they have excluded certain patient subgroups. To bridge the gap between RCT and real-world practice, the effectiveness of mepolizumab in a diverse population, including those potentially excluded from RCT, was assessed. Its effects on imaging findings and symptoms of chronic rhinosinusitis (CRS) with asthma were also assessed.

The Association of TSLP and IL-4 with Patient-Reported Outcome Measures in Chronic Rhinosinusitis with Nasal Polyps.

Am J Rhinol Allergy

Division of Otolaryngology - Head & Neck Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Background: Thymic stromal lymphopoietin (TSLP) plays an important role in mediating the type-2-inflammatory response. This study examined how TSLP and interleukin (IL)-4 levels in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) correlated with clinical and postoperative outcomes.

Methods: Solid-phase sandwich ELISA was used to analyze TSLP and IL-4 levels in mucus (n = 47), plasma (n = 17), polyp (n = 30), inferior (n = 25), and middle (n = 26) turbinate tissue collected during functional endoscopic sinus surgery (FESS) in CRSwNP patients (n = 76) and controls (n = 11).

Background: The present study explores the effect of sociodemographics and comorbidities on the calculated minimal clinically important difference (MCID) for 22-item Sinonasal Outcome Test (SNOT-22) scores in patients with medically treated chronic rhinosinusitis (CRS). The importance of delineating a threshold to indicate clinically meaningful changes perceived by a patient is well acknowledged, yet the influence of patient-specific factors on MCID has not been fully elucidated.

Methods: Patients with CRS (n = 221) presenting to a tertiary care practice reported their change in disease burden with anchor questions following CRS-directed medical treatment.
