Pingree G, Bentan M, Fitzpatrick T, Schuman T. Impact of elexacaftor/tezacaftor/ivacaftor CFTR modulator therapy on rates of endoscopic sinus surgery in cystic fibrosis. Int Forum Allergy Rhinol 2024. [PMID: 38958588 DOI: 10.1002/alr.23400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 05/24/2024] [Accepted: 06/14/2024] [Indexed: 07/04/2024]
Abstract
BACKGROUND Elexacaftor/tezacaftor/ivacaftor (ETI), a combination cystic fibrosis transmembrane receptor (CFTR) modulator, has demonstrated improved pulmonary outcomes in individuals with cystic fibrosis (CF). However, ETI's impact on functional endoscopic sinus surgery (FESS) remains unclear. METHODS The TriNetX Analytics Research Network, consisting of 120 million global de-identified electronic medical records, was queried from 2012 to 2023 for subjects with CF who underwent sinus surgery.1 Patients on ETI prior to FESS (n = 6,056) were propensity score matched to control individuals with CF not on CFTR modulators (n = 37,906) and those on other FDA-approved CFTR modulators (tezacaftor/ivacaftor, lumacaftor/ivacaftor, and ivacaftor) (n = 2437) based on relevant factors. The primary outcome was the absolute risk reduction (ARR) of undergoing FESS. Secondary outcomes included ARR of CF-related pulmonary exacerbations and hospital admission from 0 to 6, 6 to 12, and 12 to 24 months following FESS. RESULTS ETI use demonstrated a significant ARR for FESS when compared to CF patients not on CFTR modulators (2.12%; 95% confidence interval [CI] 1.5-2.75; p-value < 0.0001) and those on other CFTR modulators (4.7%; 95% CI 3.54-5.85; p-value < 0.0001). No significant differences occurred in secondary outcomes between ETI and non-CFTR modulator groups, except for reduced CF-related pulmonary exacerbations from 0 to 6 months post-FESS. Additionally, a significant reduction in pulmonary exacerbations was observed at all time points and hospital admissions within 6 months following FESS compared to those using other CFTR modulators. CONCLUSIONS In a large dataset, CF patients on ETI demonstrated significantly reduced risk of FESS, pulmonary exacerbations, and hospital admission compared to patients not on CFTR modulators or those on other CFTR modulators, suggesting improved sinonasal disease and overall health status in CF.

Glutathione and bicarbonate nanoparticles improve mucociliary transport in cystic fibrosis epithelia. Int Forum Allergy Rhinol 2024; 14:1026-1035. [PMID: 37975554 PMCID: PMC11098968 DOI: 10.1002/alr.23301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 10/16/2023] [Accepted: 10/31/2023] [Indexed: 11/19/2023]
Abstract
INTRODUCTION Cystic fibrosis (CF) airway disease is characterized by thick mucus and impaired mucociliary transport (MCT). Loss of functional cystic fibrosis transmembrane receptor (CFTR) leads to acidification and oxidation of airway surface mucus. Replacing bicarbonate (HCO3 -) topically fails due to rapid reabsorption and neutralization, while the scavenging antioxidant, glutathione sulfhydryl (GSH), is also rapidly degraded. The objective of this study is to investigate GSH/NaHCO3 nanoparticles as novel strategy for CF airway disease. METHODS GSH/NaHCO3 poly (lactic-co-glycolic acid) nanoparticles were tested on primary CF (F508del/F508del) epithelial cultures to evaluate dose-release curves, surface pH, toxicity, and MCT indices using micro-optical coherence tomography. In vivo tests were performed in three rabbits to assess safety and toxicity. After 1 week of daily injections, histopathology, computed tomography (CT), and blood chemistries were performed and compared to three controls. Fluorescent nanoparticles were injected into a rabbit with maxillary sinusitis and explants visualized with confocal microscopy. RESULTS Sustained release of GSH and HCO3 - with no cellular toxicity was observed over 2 weeks. Apical surface pH gradually increased from 6.54 ± 0.13 (baseline) to 7.07 ± 0.10 (24 h) (p < 0.001) and 6.87 ± 0.05 at 14 days (p < 0.001). MCT, ciliary beat frequency, and periciliary liquid were significantly increased. When injected into the maxillary sinuses of rabbits, there were no changes to histology, CT, or blood chemistries. Nanoparticles penetrated rabbit sinusitis mucus on confocal microscopy. CONCLUSION Findings suggest that GSH/NaHCO3 - nanoparticles are a promising treatment option for viscous mucus in CF and other respiratory diseases of mucus obstruction such as chronic rhinosinusitis.

Predictors of Sinonasal Improvement After Highly Effective Modulator Therapy in Adults with Cystic Fibrosis. Laryngoscope 2024.

Abstract
OBJECTIVES The 22-question SinoNasal Outcome Test (SNOT-22) assesses chronic rhinosinusitis (CRS) severity. We aimed to identify predictors of SNOT-22 score improvement following highly effective modulator therapy (HEMT) initiation and to corroborate the SNOT-22 minimal clinically important difference (MCID) in adults with cystic fibrosis (CF). METHODS Prospective observational data was pooled from four studies across 10 US centers investigating people with CF (PwCF) and CRS. Three studies evaluated HEMT's impact on CRS. For participants enrolled prior to HEMT initiation, SNOT-22 scores were obtained at baseline and after 3-6 months of HEMT. Multivariate regression identified predictors of improvement. Cronbach's alpha and four distribution-based methods were used to assess internal consistency and calculate the MCID of the SNOT-22. RESULTS A total of 184 PwCF participated with mean baseline SNOT-22 scores ranging from 18.1 to 56.7. Cronbach's alpha was ≥0.90 across sites. Participants at sites with pre- and post-HEMT data reported improvement in SNOT-22 scores after initiating HEMT (all p < 0.05). Worse baseline SNOT-22 score (odds ratio (OR): 1.05, p < 0.001, 95% CI: 1.02-1.08), F508del homozygosity (OR: 4.30, p = 0.040, 95% CI: 1.14-18.99), and absence of prior modulator therapy (OR: 4.99, p = 0.017, 95% CI: 1.39-20.11) were associated with greater SNOT-22 improvement. The mean MCID calculated via distribution-based methods was 8.5. CONCLUSION Worse baseline sinonasal symptoms, F508del homozygosity, and absence of prior modulator therapy predicted greater improvement after HEMT initiation. The mean MCID for SNOT-22 in PwCF is 8.5 points, similar to non-CF individuals with CRS, and provides a threshold specifically for PwCF. The SNOT-22 has strong internal consistency in PwCF.

Abstract
BACKGROUND Comorbid chronic rhinosinusitis (CRS) remains unresolved for many people with cystic fibrosis (PwCF). While highly effective modulator therapy improves quality-of-life and symptom severity, the impact of this intervention and other factors associated with pursuing endoscopic sinus surgery (ESS) remains understudied. METHODS Adult PwCF + CRS were enrolled into a prospective, observational, multi-institutional study. Participants completed validated outcome measures to evaluate respiratory symptom severity, depression, headache, and sleep quality, as well as nasal endoscopy, sinus computed tomography (CT), and olfactory testing. Bivariate comparisons and regression modeling evaluated treatment cofactors, disease characteristics, and outcome measures associated with pursuing ESS. RESULTS Sixty PwCF were analyzed, including 24 (40%) who elected ESS. Pursuing ESS was associated with worse SinoNasal Outcome Test (SNOT-22) total, rhinologic, psychological, and sleep dysfunction domain scores; worse Patient Health Questionnaire-9-Revised depression scores; worse Pittsburgh Sleep Quality Index total scores; worse weight, role, emotion, and eating domain scores on the Cystic Fibrosis Questionnaire-Revised; more severe disease on nasal endoscopy; and lack of modulator therapy (all p < 0.050). Multivariable regression identified that worse SNOT-22 total score was associated with electing ESS (odds ratio [OR] 1.09, 95% confidence interval [CI] 1.02-1.16, p = 0.015) and elexacaftor/tezacaftor/ivacaftor (ETI) treatment (OR 0.04, 95% CI 0.004-0.34, p = 0.004) was associated with pursing medical therapy. CONCLUSIONS Worse sinonasal symptom burden, lack of ETI treatment, sleep quality, depression, and nasal endoscopy scores were associated with electing ESS, while lung disease severity and sinus CT scores were not. ETI use was associated with lower odds of pursuing ESS independent of sinonasal symptom burden.

Surgical and medical management of chronic rhinosinusitis in pediatric cystic fibrosis patients: Impact on olfactory symptoms. Int J Pediatr Otorhinolaryngol 2024; 179:111898. [PMID: 38452513 DOI: 10.1016/j.ijporl.2024.111898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 01/13/2024] [Accepted: 02/16/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND AND PURPOSE Olfactory dysfunction (OD) commonly occurs in patients with sinonasal dysfunction, but the prevalence and severity of olfactory issues in adolescents with cystic fibrosis (AwCF) is unclear. OD may contribute to dietary deficiencies and exacerbate nutritional challenges. We sought to review literature on the effectiveness of medical and surgical management of sinonasal symptoms in AwCF and the associated impact on olfactory function. METHODS We performed a systematic literature search of PubMed, Embase, Web of Science, and Ebsco CINAHL from 1980 to 2022 per PRISMA-ScR protocols to conduct a scoping review in an effort to compile data on study design, patient demographics, clinical characteristics and outcomes, along with risk of bias. RESULTS Of 368 abstracts, 3 articles exclusively evaluated AwCF for a total of 34 patients. Two studies evaluated endoscopic sinus surgery (ESS) and dornase alfa. An additional 6 articles were included for mixed pediatric and adult CF populations totaling 313 patients. Interventions included ESS, elexacaftor-tezacaftor-ivacaftor (ETI), ivacaftor, saline, dornase alfa, hyaluronic acid, and hyaluronic acid-tobramycin combination. Outcome measures included subjective assessment of OD using non-validated (4/9) and validated (4/9) surveys, and psychophysical (1/9) smell testing. Studies evaluating ESS, FESS, dornase alfa, ivacaftor, and both hypertonic and isotonic saline reported statistically significant improvement in OD, whereas ETI failed to improve OD despite improvement in other quality of life measures. CONCLUSIONS There is limited data regarding the impact of medical and surgical interventions on olfaction for AwCF. Assessment of olfaction was often limited to subjective and qualitative self-report. We suggest that tracking of olfactory outcomes with psychophysical testing is critical in this population with dietary challenges and weight management issues.

Abstract
Chronic rhinosinusitis is a common manifestation of CF that is associated with impaired quality of life and can be difficult to treat. CFTR modulator therapy has resulted in significant improvements in lower respiratory and nutritional outcomes for people with CF however their impact on chronic rhinosinusitis has received less attention. We review the literature in relation to chronic rhinosinusitis in CF and examine the impact of CFTR modulator therapy on symptoms, imaging, endoscopic appearances, and olfactory outcomes in the treatment of chronic rhinosinusitis. While an overall improvement in symptoms, imaging and endoscopic appearances is seen in response to treatment, limited impact is documented on olfaction. Outcome measures employed were heterogenous, limiting comparison of findings. There is a need for well powered prospective real-world studies with standardised outcome measures.

Abstract
BACKGROUND Cystic fibrosis (CF) is a complex systemic disease involving numerous organ systems. With improved treatment options and increasing life expectancy of persons with CF (PwCF), extrapulmonary manifestations are coming increasingly into the focus. From birth, almost all PwCF have radiologically detectable pathologies in the upper airways attributable to CF-associated chronic rhinosinusitis (CF-CRS). OBJECTIVE The aim of this work is to provide an up-to-date overview of CF-CRS from the otorhinolaryngology perspective and to provide the reader with background knowledge and current developments. PATHOPHYSIOLOGY The cystic fibrosis transmembrane conductance regulator (CFTR) gene defect leads to increased viscosity of sinonasal secretions and reduced mucociliary clearance, causing chronic infection and inflammation in the upper airway segment and, consequently, to CF-CRS. CLINICAL PICTURE AND DIAGNOSTICS The clinical picture of CF-CRS comprises a wide spectrum from asymptomatic to symptomatic courses. CF-CRS is diagnosed clinically and radiologically. THERAPY Sinonasal saline irrigation is recommended as a conservative treatment measure. Topical corticosteroids are also commonly used. Surgical therapy is reserved for highly symptomatic treatment-refractory patients without a sufficient response to conservative treatment including CFTR modulator (CFTRm) therapies. Depending on the CFTR mutation, CFTRm therapies are the treatment of choice. They not only improve the pulmonary and gastrointestinal manifestations in PwCF, but also have positive effects on CF-CRS. CONCLUSION The ENT specialist is part of the interdisciplinary team caring for PwCF. Depending on symptom burden and treatment responsiveness, CF-CRS should be treated conservatively and/or surgically. Modern CFTRm have a positive effect on the clinical course of CF-CRS.

Aminoglycoside-induced sensorineural hearing loss in pediatric cystic fibrosis patients: A retrospective cohort study. Heliyon 2024; 10:e25190. [PMID: 38333844 PMCID: PMC10850907 DOI: 10.1016/j.heliyon.2024.e25190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 01/21/2024] [Accepted: 01/22/2024] [Indexed: 02/10/2024] Open
Abstract
Background Pulmonary infections by gram-negative organisms are important in cystic fibrosis (CF). Aminoglycosides (AG) are often part of the treatment regimen. However, they are a well-known cause of ototoxicity. Even minimal hearing impairment in children could have a future impact on functional well-being.We aimed to investigate the progression of sensorineural hearing loss (SNHL) over several years in pediatric CF patients, and to identify risk factors, such as the use of AG, including both intravenous (IV) and inhaled AG. Methods Retrospective analyses of patient records from children and adolescents followed up at the CF clinic of the Antwerp University Hospital, Belgium, were performed. We collected data on age, sex, pure-tone audiometry, and the use of AG. Descriptive and binary logistic regression analyses, and if indicated generalized estimating equations (GEE) analyses were performed. Results Forty pediatric patients were enrolled in the study taking part from 2013 to 2020. Pure-tone audiometry revealed an important rate of SNHL over several years, with a prevalence of 29 % for high-frequency SNHL (i.e. 8 kHz). Increasing age was identified as a significant risk factor for the development of SNHL at 8 kHz if 5 or more IV AG courses (p = 0.01) were reported or when IV AG were combined with inhaled AG (p = 0.002). Conclusions Age combined with the use of IV AG (≥5 courses or in combination with inhaled AG) are predictive for developing high-frequency SNHL (i.e. 8 kHz). We suggest routine annual hearing screening (incl. high-frequency thresholds) in CF patients, starting from childhood.

Abstract
OBJECTIVE This study investigates the effect of pre-operative cluster care nursing on patient compliance during preoperative isolation of pediatric patients from their family members before cochlear implant surgery. STUDY METHODS A total of 350 pediatric patients who underwent cochlear implant surgery at Sichuan Rehabilitation Hospital from January 2021 to December 2022 were enrolled. The children were divided into two groups:Experimental group (group E) consisted of 182 children who received pre-operative cluster care nursing, and control group (group C) consisted of 168 children who received pre-operative routine nursing. The compliance scores of the two groups of patients when separated from their families before entering the operating room and the number of patients requiring intravenous injection of midazolam were recorded. RESULTS The compliance scores of group E were significantly lower than those of group C (t = 4.141, P < 0.001). The percentage of patients requiring intravenous injection of midazolam was recorded: it was 21.98% (40/182) in group E and 42.26% (71/168) in group C. Notably, the injection rate of midazolam in group E was significantly lower than that in group C (χ2 = 16.597, P < 0.001). CONCLUSION Pre-operative cluster care nursing can improve patient compliance and reduce the use of sedative drugs during preoperative isolation of pediatric patients from their family members for cochlear implant surgery.

Red ginseng aqueous extract improves mucociliary transport dysfunction and histopathology in CF rat airways. J Cyst Fibros 2023; 22:1113-1119.

Abstract
BACKGROUND We previously discovered that Korean red ginseng aqueous extract (RGAE) potentiates the TMEM16A channel, improved mucociliary transport (MCT) parameters in CF nasal epithelia in vitro, and thus could serve as a therapeutic strategy to rescue the MCT defect in cystic fibrosis (CF) airways. The hypothesis of this study is that RGAE can improve epithelial Cl- secretion, MCT, and histopathology in an in-vivo CF rat model. METHODS Seventeen 4-month old CFTR-/- rats were randomly assigned to receive daily oral control (saline, n = 9) or RGAE (Ginsenosides 0.4mg/kg/daily, n = 8) for 4 weeks. Outcomes included nasal Cl- secretion measured with the nasal potential difference (NPD), functional microanatomy of the trachea using micro-optical coherence tomography, histopathology, and immunohistochemical staining for TMEM16a. RESULTS RGAE-treated CF rats had greater mean NPD polarization with UTP (control = -5.48 +/- 2.87 mV, RGAE = -9.49 +/- 2.99 mV, p < 0.05), indicating, at least in part, potentiation of UTP-mediated Cl- secretion through TMEM16A. All measured tracheal MCT parameters (airway surface liquid, periciliary liquid, ciliary beat frequency, MCT) were significantly increased in RGAE-treated CF rats with MCT exhibiting a 3-fold increase (control, 0.45+/-0.31 vs. RGAE, 1.45+/-0.66 mm/min, p < 0.01). Maxillary mucosa histopathology was markedly improved in RGAE-treated cohort (reduced intracellular mucus, goblet cells with no distention, and shorter epithelial height). TMEM16A expression was similar between groups. CONCLUSION RGAE improves TMEM16A-mediated transepithelial Cl- secretion, functional microanatomy, and histopathology in CF rats. Therapeutic strategies utilizing TMEM16A potentiators to treat CF airway disease are appropriate and provide a new avenue for mutation-independent therapies.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is comprised of a diverse group of endotypes that cause significant morbidity for afflicted patients. While endoscopic sinus surgery helps ameliorate the disease, polyps frequently recur. Newer strategies are intended to provide access for topical steroid irrigations in attempts to improve the disease process and quality of life, and decrease overall recurrence of polyps. OBJECTIVE To review the current literature examining the latest surgical approaches for CRSwNP. METHODS Review article. RESULTS In dealing with the recalcitrant nature of CRSwNP, surgical techniques have simultaneously become more nuanced and aggressive. Bony resection in anatomically unfavorable areas such as the frontal, maxillary, and sphenoid outflow regions, replacing diseased or denuded mucosa with healthy grafts or flaps at the neo-ostia, and introducing drug-eluting biomaterials to newly opened sinus outflow tracts are highlights in the recent advancements in sinus surgery for CRSwNP. The Draf 3 or modified endoscopic Lothrop procedure has become a standard technique and demonstrated to improve quality of life and decrease polyp recurrence. A number of mucosal grafting or mucosal flap techniques have been described that cover exposed bone of the neo-ostium and evidence shows that this improves healing and diameter of the Draf 3. Partial middle turbinectomy, while controversial, appears to help decrease polyp recurrence in long-term follow-up studies. Modified endoscopic medial maxillectomy improves access to the maxillary sinus mucosa, facilitates debridement and, particularly, in the cystic fibrosis nasal polyp patient, improves overall management of the disease. Sphenoid drill-out procedure provides wider access for topical steroid irrigations and also may improve management of CRSwNP. CONCLUSION Surgical intervention remains a mainstay of therapy for CRSwNP. Newer techniques revolve around improving access for topical steroid therapy.

Abstract
PURPOSE Sinunasal symptoms and chronic rhinusinutitis are common in patients with cystic fibrosis. Cystic fibrosis transmembrane regulator (CFTR) modulators have led to dramatic improvements of respiratory symptoms and quality of life in patients with cystic fibrosis. This study aims to evaluate subjective and objective sinunasal symptoms after start of CFTR-modulator triple therapy. METHODS 43 patients (n = 6 < 18 years), treated with highly effective CFTR-modulator therapy with elexacaftor-tezacaftor-ivacaftor (ELX/TEZ/IVA) were included, as were 20 controls with cystic fibrosis but without CFTR-modulator therapy (n = 6 < 18 years). All assessed their sinunasal symptoms retrospectively and the intervention group at a mean of 9.3 (2-16) months after start of ELX/TEZ/IVA. RESULTS Improvements in SNOT-22 overall score from m = 32.7 to m = 15.7 points (p < 0.0001) as well in the nasal, emotional, otologic, and sleep subdomains could be demonstrated in the intervention group. No changes were found in the control group. Children showed lower SNOT-22 scores than adults and a reduction of SNOT-22 total score from m = 9.4 to m = 2.2 (p = 0.25) was found. 8 patients were evaluated by an otorhinolaryngologist before and after start of ELX/TEZ/IVA and showed pronounced objective clinical improvement. CONCLUSIONS Highly effective CFTR-modulator therapy has a significant positive impact on both subjective and objective sinunasal symptoms in patients with CF and some improvement could be demonstrated in children < 18 years as well.

Abstract
Chronic rhinosinusitis (CRS) is a common, yet underreported and understudied manifestation of upper respiratory disease in people with cystic fibrosis (CF). Recently developed standard of care guidelines for the management of CF CRS suggest treatment of upper airway disease may ameliorate lower airway disease. We sought to determine whether changes to sinus microbial community diversity and specific taxa known to cause CF lung disease are associated with increased respiratory disease and inflammation. We performed 16S rRNA gene sequencing, supplemented with cytokine analyses, microscopy, and bacterial culturing, on samples from the sinuses of 27 adults with CF CRS. At each study visit, participants underwent endoscopic paranasal sinus sampling and clinical evaluation. We identified key drivers of microbial community composition and evaluated relationships between diversity and taxa with disease outcomes and inflammation. Sinus community diversity was low, and the composition was unstable, with many participants exhibiting alternating dominance between Pseudomonas aeruginosa and staphylococci over time. Despite a tendency for dominance by these two taxa, communities were highly individualized and shifted composition during exacerbation of sinus disease symptoms. Exacerbations were also associated with communities dominated by Staphylococcus spp. Reduced microbial community diversity was linked to worse sinus disease and the inflammatory status of the sinuses (including increased interleukin-1β [IL-1β]). Increased IL-1β was also linked to worse sinus endoscopic appearance, and other cytokines were linked to microbial community dynamics. Our work revealed previously unknown instability of sinus microbial communities and a link between inflammation, lack of microbial community diversity, and worse sinus disease. IMPORTANCE Together with prior sinus microbiota studies of adults with CF chronic rhinosinusitis, our study underscores similarities between sinus and lower respiratory tract microbial community structures in CF. We show how community structure tracks with inflammation and several disease measures. This work strongly suggests that clinical management of CRS could be leveraged to improve overall respiratory health in CF. Our work implicates elevated IL-1β in reduced microbiota diversity and worse sinus disease in CF CRS, suggesting applications for existing therapies targeting IL-1β. Finally, the widespread use of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy has led to less frequent availability of spontaneous expectorated sputum for microbiological surveillance of lung infections. A better understanding of CF sinus microbiology could provide a much-needed alternative site for monitoring respiratory infection status by important CF pathogens.
