Background It remains unclear how much chronic rhinosinusitis (CRS) patients with bacterial biofilms can benefit from functional endoscopic sinus surgery (FESS). We aimed to evaluate whether biofilm-forming bacteria was associated with quality of life (QOL) improvement after FESS. Methods This retrospective cohort study included adult CRS patients who underwent FESS from 2008 to 2011. Sinus samples were taken to evaluate for biofilm-formation in vitro using a modified Calgary Biofilm Detection Assay. QOL was measured before FESS, and 1-month, 3-month, and 6-month after FESS using 22-item Sino-Nasal Outcome Test (SNOT-22) scores. Patients' characteristics and medications were collected. Clinical significant QOL change was defined as a difference of at least 0.5 standard deviation (SD) of baseline SNOT-22 score in the reference group. Results A total of 156 patients had complete data, and 15% had biofilm-forming bacteria (n = 24). Patients with biofilm-forming bacteria had significantly worse preoperative SNOT-22 scores compared to patients without biofilm-forming bacteria (48 ± 20 vs 38 ± 23, p = 0.048). Both groups had clinically significant QOL improvement after FESS, and the differences in their 1-month (23 ± 19 vs 17 ± 20) and 3-month (27 ± 18 vs 18 ± 19) post-FESS SNOT-22 scores were not significant. However, patients with biofilm-forming bacteria demonstrated significantly less QOL improvement than patients without biofilm-forming bacteria from pre-FESS to 6-month post-FESS visits after adjusting for clinical factors (35 ± 25 vs 14 ± 15; β-coefficient = 0.71; 95% confidence interval [CI], 0.13 to 1.28; p = 0.016). Conclusion CRS patients with biofilm-forming bacteria demonstrated clinically significant QOL improvement following FESS, but the degree of improvement was decreased overtime and became significantly worse than patients without biofilm-forming bacteria by 6-month follow-up. This QOL worsening was independent of other risk factors for CRS. [ABSTRACT FROM AUTHOR]

Background It is unclear whether chronic rhinosinusitis (CRS) patients with both nasal polyps and asthma have different quality of life (QOL) improvement after functional endoscopic sinus surgery (FESS). We aimed to determine whether CRS patients with asthma and nasal polyps had a greater QOL improvement after FESS compared to patients without asthma or polyps. Methods This retrospective analysis included adult CRS patients who underwent FESS between 2007 and 2011. QOL was measured using the 22-item Sino-Nasal Outcome Test (SNOT-22). Variables collected included baseline demographics, clinical factors, SNOT-22 scores before FESS, and 1 month, 3 months, and 6 months post-FESS. Groups tested were asthma alone, polyps alone, asthma and polyps, and no asthma or polyps. Linear mixed-effects regression model was performed to calculate β-coefficients, which represent the adjusted mean QOL differences. Results Among the 376 patients included, 40.16% had both asthma and polyps (n = 151), 14.36% had asthma alone (n = 54), 19.45% had polyps alone (n = 75), and 25.53% had no asthma or polyps (n = 96). After adjusting for all factors, there were significantly more QOL improvements in patients with both asthma and nasal polyps from baseline to 1-month (β-coefficient = −10.05; 95% CI, −15.86 to −4.23; p = 0.001) and 3-month follow-up (β-coefficient = −8.27; 95% CI, −14.98 to −1.56; p = 0.016), and patients with asthma alone from baseline to 6-month follow-up (β-coefficient = −8.78; 95% CI, −17.45 to −0.11; p = 0.047), when compared to patients without asthma or nasal polyps. Conclusion CRS patients with both asthma and nasal polyps or asthma alone experience a larger QOL benefit from FESS immediately after FESS compared to CRS patients without asthma or polyps.

Background Patients with diabetes mellitus (DM) are known to be prone to infection. However, the association between diabetes and chronic rhinosinusitis (CRS) has not been well studied. We sought to determine the effects of DM on CRS culture results and quality of life (QOL) after functional endoscopic sinus surgery (FESS). Methods We conducted a retrospective cohort study. Adult CRS patients undergoing FESS were recruited from October 1, 2007 to December 31, 2011. Patient demographics, comorbidities, medication use, and Lund-Mackay CT scores were collected prior to FESS. Intraoperative culture was obtained. Preoperative and 1-month, 3-month, and 6-month postoperative QOL was measured by scores on the 22-item Sinonasal Outcome Test (SNOT-22). A mixed effects model was performed for analysis. Results Among the 376 CRS patients included, 19 patients (5.05%) had DM. Compared to non-DM patients, DM patients were significantly more likely to have Pseudomonas aeruginosa (26.32% vs 7.56%; p = 0.004) and Gram-negative rods (26.32% vs 8.96%; p = 0.013), but there was no significant difference in the prevalence of Staphylococcus aureus; DM patients were also significantly more likely to have nasal polyps and gastroesophageal reflux disease. Additionally, DM patients had significantly less improvement of postoperative SNOT-22 scores from baseline to 6-month follow-up than non-DM patients (adjusted mean = 11.14, 95% CI (0.14, 22.15), p = 0.047) after adjusting for all the other risk factors for CRS. Conclusion DM patients may be prone to Gram-negative bacterial sinus infections, and have significantly worse short-term postoperative QOL. Special postoperative care may need to be considered in CRS patients with DM. [ABSTRACT FROM AUTHOR]

All patients on CFTR modulators before ELX/TEZ/IVA were DF508 homozygotes on either TEZ/IVA or LUM/IVA. In summary, the novel highly-effective CFTR modulator ELX/TEZ/IVA leads to significantly improved sinonasal QoL in CF adults as measured by the SNOT-22 questionnaire. [Extracted from the article]

Background Despite their widespread use, antibiotics have not been shown to improve chronic rhinosinusitis (CRS) outcomes. We aimed to determine whether culture-inappropriate postoperative antibiotic therapy was associated with less quality-of-life (QOL) improvement following functional endoscopic sinus surgery (FESS). Methods This retrospective cohort study recruited 376 adult CRS patients undergoing FESS between October 1, 2007 to December 31, 2011. Patient demographics, comorbidities and medications were collected at baseline. Trimethoprim-sulfamethoxazole and clindamycin were administered for 2 weeks postoperatively. The antibiotic appropriateness was determined based on bacterial resistance profile of organisms identified during intraoperative culture. The QOL outcome was defined as change of 22-item Sinonasal Outcome Test scores from preoperative visit to 1-month, 3-month, and 6-month post-FESS. Clinically significant difference was defined as at least 0.5 standard deviations (SD) of baseline QOL score in the reference group. Mixed-effects regression models were performed. Results Seven percent of patients (n = 27) had culture-inappropriate antibiotic therapy, and additional 5% (n = 19) had culture-specific antibiotic adjustment. Compared to patients with culture-appropriate antibiotics, patients with culture-inappropriate antibiotics had significantly less improvement of QOL from baseline to postoperative 1-month and 3-month follow-up where the difference became clinically significant; patients with antibiotic adjustment had more QOL improvement from baseline to 1-month follow-up, but their QOL worsened at 3-month follow-up, and these changes were not clinically significant. However, all effects washed out at 6-month follow-up with no significant differences. Conclusion Culture-inappropriate postoperative antibiotic therapy decreased short-term QOL improvement to a clinically meaningful level after FESS. Culture guided selection of antibiotics may improve short-term FESS outcome. [ABSTRACT FROM AUTHOR]
