Chronic rhinosinusitis with nasal polyps management in the biologic therapy era: an international YO-IFOS survey

Real-world outcomes on quality-of-life improvement in patients with nasal polyposis treated with mepolizumab. RINOSUR study

Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by nasal obstruction, reduced sense of smell, rhinorrhea, and facial pain for more than 12 weeks, significantly affecting quality of life (QoL), especially in patients with NSAID-exacerbated respiratory disease (NERD). Initial treatment includes intranasal corticosteroids and nasal irrigations, followed by systemic corticosteroids (SC) in severe cases, as well as endoscopic sinus surgery (ESS) and biological agents. Mepolizumab, a monoclonal antibody against IL-5, has been shown to reduce eosinophilic inflammation in CRSwNP. This study evaluates the improvement in quality of life of patients with CRSwNP treated with mepolizumab before December 2023, recorded by the RINOSUR group. A retrospective observational multicenter cohort study is presented in adult patients with severe asthma and concomitant CRSwNP, treated with mepolizumab 100 mg. Variables such as sex, asthma, allergies, NERD, corticosteroid dependence, and serum eosinophil count were recorded. All patients underwent nasal endoscopy and completed the SNOT22 questionnaire. Therapeutic response was evaluated at 12 months. Out of 143 patients recruited, only 28.6% had the necessary data. 61% were women with a mean age of 55 years. All were corticosteroid-dependent and had required at least one ESS. A 22% reduction in SC cycles was observed, and no patient required revision surgery in the 12 months following treatment. The SNOT22 score was reduced by 53 points, and serum eosinophilia also showed a significant decrease. Mepolizumab is effective in treating severe uncontrolled CRSwNP, improving QoL and reducing dependence on systemic corticosteroids. Its activity is monitored by peripheral blood eosinophilia. Consistency in data collection is crucial to evaluate efficacy and manage the disease.

Prescribing Practices and Barriers of Biologics for Chronic Rhinosinusitis Amongst Otolaryngologists

OBJECTIVE(S)

Biologics for chronic rhinosinusitis with nasal polyposis (CRSwNP) are an evolving therapeutic option, but there are limited data on physician experiences in prescribing them. The goal of this study was to gain a better understanding of these experiences including prescribing practices, patient factors which guide prescriber decision, and physician and patient-reported issues which might limit cost-effectiveness of these therapies.

METHODS

A survey was distributed to attending otolaryngologists using the Canadian Society of Otolaryngology (CSOHNS) email distribution and eSurvey program. Responses were tabulated for the entire cohort and compared between rhinologists and non-rhinologists where appropriate. Frequencies and proportions were expressed as a percentage of total respondents. Fisher's exact test was used for statistical analysis between groups.

RESULTS

Seventy-nine total survey responses were recorded representing a response rate of 43%. Significantly more rhinologists reported prescribing biologic medications on their own (100% vs. 50%; p < 0.001) and a higher proportion (1 to 10% vs. <1%) of their patients were on biologics compared with non-rhinologists (p = 0.023). Rhinologists were more likely to consider poor response to medical therapies, need for rescue steroids, and comorbid type 2 conditions in their decision to pursue biologics than non-rhinologists, but they also experienced poorer assistance from patient support programs and less availability to medications.

CONCLUSION

Rhinologists are more comfortable with prescribing and managing biologics for CRSwNP compared with non-rhinologist colleagues. Clinicians prescribing biologic medications for CRSwNP should be familiar with guidelines, indications, and potential adverse events.

Is generative pre-trained transformer artificial intelligence (Chat-GPT) a reliable tool for guidelines synthesis? A preliminary evaluation for biologic CRSwNP therapy

INTRODUCTION

Biologic therapies for Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) have emerged as an auspicious treatment alternative. However, the ideal patient population, dosage, and treatment duration are yet to be well-defined. Moreover, biologic therapy has disadvantages, such as high costs and limited access. The proposal of a novel Artificial Intelligence (AI) algorithm offers an intriguing solution for optimizing decision-making protocols.

METHODS

The AI algorithm was initially programmed to conduct a systematic literature review searching for the current primary guidelines on biologics' clinical efficacy and safety in treating CRSwNP. The review included a total of 12 studies: 6 systematic reviews, 4 expert consensus guidelines, and 2 surveys. Simultaneously, two independent human researchers conducted a literature search to compare the results. Subsequently, the AI was tasked to critically analyze the identified papers, highlighting strengths and weaknesses, thereby creating a decision-making algorithm and pyramid flow chart.

RESULTS

The studies evaluated various biologics, including monoclonal antibodies targeting Interleukin-5 (IL-5), IL-4, IL-13, and Immunoglobulin E (IgE), assessing their effectiveness in different patient populations, such as those with comorbid asthma or refractory CRSwNP. Dupilumab, a monoclonal antibody targeting the IL-4 receptor alpha subunit, demonstrated significant improvement in nasal symptoms and quality of life in patients with CRSwNP in several randomized controlled trials and systematic reviews. Similarly, mepolizumab and reslizumab, which target IL-5, have also shown efficacy in reducing nasal polyp burden and improving symptoms in patients with CRSwNP, particularly those with comorbid asthma. However, additional studies are required to confirm the long-term efficacy and safety of these biologics in treating CRSwNP.

CONCLUSIONS

Biologic therapies have surfaced as a promising treatment option for patients with severe or refractory CRSwNP; however, the optimal patient population, dosage, and treatment duration are yet to be defined. The application of AI in decision-making protocols and the creation of therapeutic algorithms for biologic drug selection, could offer fascinating future prospects in the management of CRSwNP.

Expert consensus on the use of systemic glucocorticoids for managing eosinophil-related diseases

Eosinophil-related diseases represent a group of pathologic conditions with highly heterogeneous clinical presentation and symptoms ranging from mild to critical. Both systemic and localized forms of disease are typically treated with glucocorticoids. The approval of novel biologic therapies targeting the interleukin-5 pathway can help reduce the use of systemic glucocorticoids (SGC) in eosinophilic diseases and reduce the risk of SGC-related adverse effects (AEs). In this article, a panel of experts from different medical specialties reviewed current evidence on the use of SGC in two systemic eosinophilic diseases: Eosinophilic Granulomatosis with PolyAngiitis (EGPA) and HyperEosinophilic Syndrome (HES); and in two single-organ (respiratory) eosinophilic diseases: Chronic RhinoSinusitis with Nasal Polyps (CRSwNP) and Severe Asthma with Eosinophil Phenotype (SA-EP), and contrasted it with their experience in clinical practice. Using nominal group technique, they reached consensus on key aspects related to the dose and tapering of SGC as well as on the initiation of biologics as SGC-sparing agents. Early treatment with biologics could help prevent AEs associated with medium and long-term use of SGC.

Management of patients with chronic rhinosinusitis with nasal polyps in Spain: learnings from a nationwide survey of otorhinolaryngologists

PURPOSE

To describe the self-reported practices on the diagnosis, treatment, and follow-up of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) by ear, nose, and throat (ENT) specialists in Spain to identify potential areas for management optimization.

METHODS

A cross-sectional online survey with 16 questions was carried out. Recruitment was performed by emailing registered ENT specialists in the Spanish Society of Otorhinolaryngology and Head and Neck Surgery (SEORL-CCC).

RESULTS

In total, 127 ENT specialists completed the survey. Fifty-one percent of respondents combined clinical criteria and objective evidence of mucosal inflammation to diagnose CRSwNP. Patient interview and, to a lower degree, a visual analogue scale were the most employed diagnostic tools to quantify symptom severity. Less than half (45%) routinely used the 22-item sino-nasal outcomes test (SNOT-22) to assess the impact of CRSwNP disease in quality of life. The use of patient-reported outcomes and other clinical evaluation tools showed a larger uptake among ENT specialists that worked at an ENT department with an available rhinology unit. Almost all the specialists surveyed (95%) recommended biological treatment, particularly in patients with uncontrolled CRSwNP with respiratory comorbidities (76%), as well as in candidates for revision surgery (66%).

CONCLUSION

Spanish otorhinolaryngologists showed a trend toward incorporating CRSwNP guideline recommendations in their clinical practice. The observed low uptake of patient-reported outcomes and objective clinical evaluation tools in routine clinical practise have been identified as areas for optimizing the management of patients with CRSwNP.

Orally administered Chinese herbal therapy to assist post-surgical recovery for chronic rhinosinusitis-A systematic review and meta-analysis

This systematic review and meta-analysis aims to: assess the effectiveness and safety of orally administered Chinese herbal medicines (CHMs) as adjuncts to the post-surgical management of chronic rhinosinusitis (CRS); inform clinicians of the current evidence; identify the best available evidence; and suggest directions for further research. Randomised controlled trials (RCTs) were identified from searches of nine databases plus clinical trial registries. Participants were adults and/or children diagnosed with sinusitis or rhinosinusitis, with or without nasal polyps, who had received surgery. Interventions were CHMs used orally following surgery for CRS as additions to conventional post-surgical management. Controls received conventional post-surgical management without CHMs. Studies reported results for Sino-Nasal Outcome Test (SNOT), visual analogue scales (VAS), Lund-Mackay computed tomography score (LM), Lund-Kennedy endoscopic score (LK), mucociliary transport time (MTT), mucociliary transport rate (MTR), mucociliary clearance (MC) or quality of life (QoL). Twenty-one RCTs were included. All used oral CHMs following functional endoscopic sinus surgery (FESS). The pooled results showed no significant difference between groups for SNOT-20 at the end of treatment (EoT) but there was a significant difference at follow up (FU) in favour of additional CHMs. The VAS for total nasal symptoms (VAS-TNS) showed greater improvements in the CHM groups at EoT and FU. Only FU data were reported for LM which showed greater improvement in the CHM groups. LK showed greater improvements at EoT and FU. The measures of mucociliary transport (MTT, MTR, and MC) each showed significantly greater improvement at EoT in the group that received additional CHMs. No study reported QoL. Adverse events were not serious, but reporting was incomplete. The meta-analyses suggested the addition of oral CHMs to conventional management following FESS may improve recovery. However, most studies were not blinded, and substantial heterogeneity was evident in some meta-analyses. Blinded studies are required to further investigate the roles of oral CHMs in post-surgical recovery. Systematic review registration number: The protocol was registered in PROSPERO (CRD42019119586).
