Nasal polyps impact in severe asthma patients: evidences from the SANI

Relief of Airflow Limitation and Airway Inflammation by Endoscopic Sinus Surgery in a Patient with Severe Asthma with Eosinophilic Chronic Rhinosinusitis

Although endoscopic sinus surgery (ESS) is beneficial in improving asthma symptoms, its impact on the lung function in patients with asthma and chronic rhinosinusitis remains unclear. We herein report a case of severe asthma with eosinophilic chronic rhinosinusitis, in which ESS substantially improved airflow limitation and concomitantly reduced fractional exhaled nitric oxide and blood eosinophil counts. ESS likely relieved airflow limitation by suppressing type 2 inflammatory pathways. This case highlights ESS as a promising strategy for achieving clinical remission in patients with severe asthma and chronic rhinosinusitis.

Practical recommendations for managing severe chronic rhinosinusitis with nasal polyps in the era of biologics

Objective

We conducted a national survey to understand how rhinology practice has changed with the advent of biologics and how this affected patients with uncontrolled, severe chronic rhinosinusitis with nasal polyps (CRSwNP). We aimed to analyse the results of the survey and infer practical recommendations for clinical practice.

Methods

A group of ear, nose, and throat specialists (ENTs) experienced in the management of CRSwNP developed a 74-question survey. ENTs from rhinology centres authorised to prescribe biologics in the context of the national health system were invited to answer it between 01/05/2022 and 31/07/2022. The responses underwent descriptive analyses, and the authors discussed the results and derived practical recommendations for clinical practice.

Results

ENTs working in rhinology centres changed their practices coinciding with the advent of biologics. CRSwNP evaluations have become more complex because they involve diagnostic confirmation, determining the patients' immunologic profile, and other factors. We observed heterogenous behaviours in practice that may be conditioned by the novelty of the topic. The results of the survey were used to develop practical recommendations for ENTs and are summarised herein.

Conclusions

Clinical practice in rhinology outpatient clinics has changed profoundly in the era of biologics. Our practical recommendations for clinicians working in rhinology centres are expected to help standardise practice and improve care.

Uso de glucocorticoides sistémicos para el tratamiento del asma grave: Consenso multidisciplinar español

Background and aim

Since their effectiveness was initially demonstrated, oral corticosteroids (OCS) have been routinely used to treat asthma. We now know that their usage is linked to the development of side effects such osteoporosis and adrenal insufficiency. This is an observational study based on Delphi methodology. The questionnaire was divided into 4 sections: OCS generalities, maintenance treatment, short-term treatment, and adverse events.

Materials and methods

Two rounds of a 68-item questionnaire were completed by a panel of 48 allergists and pneumologists.

Results

Definitions were agreed upon, as was the proper use of OCS in the treatment of severe asthma. The experts agreed that the use of OCS should be minimized as much as possible and that in the event of maintenance treatments, a slow and progressive tapering strategy should be used. They also emphasized the importance of standardizing the technique for measuring the amount of SCG delivered in both cases.

Conclusions

This consensus document attempts to bring together scientifically supported suggestions from specialists in the management of asthma to reduce the use of OCS in Spain.

Healthcare utilisation and health-related quality of life of severe asthma patients in Singapore

BackgroundNotwithstanding unequivocal consensus on the disproportionate effect of severe asthma (SA) on asthma morbidity, healthcare utilisation, quality of life, work impairment and socioeconomic burden, the burden of SA patients in Singapore has not been appraised.ObjectivesTo determine the burden of disease and extent of quality of life impairment in SA patients in Singapore.MethodsA cross-sectional analysis of SA patients seen in Singapore General Hospital (2020-2021) to investigate emergency healthcare utilization, oral corticosteroid (OCS) burden and health-related quality of life (HRQoL) with primary endpoint EuroQoL-5 Dimension three-level (EQ-5D-3L) scores. The empirical measurement properties of the EQ-5D utility index in SA were comprehensively assessed through multivariate regression analyses.ResultsA total of 336 SA patients were recruited, 51.2% of SA patients had at least one acute healthcare resource utilization during the previous year, with 25.6% of patients having an emergency healthcare visit to the hospital. Overall mean (SD) EQ-5D-3L and EQ-5D-3L utility scores in SA patients were 6.22 (1.51) and 0.77 (0.30), respectively. EQ-5D utility scores were 0.14 lower in uncontrolled vs controlled asthma and 0.09 lower in the presence of severe exacerbation, whereas barely changed by maintenance OCS dose and airflow limitation.ConclusionSA patients were found to have high disease burden, high healthcare resource utilization and OCS use, low biologics usage, poor HRQoL and utility in comparison with other chronic diseases.

Biologics for severe uncontrolled chronic rhinosinusitis with nasal polyps: a change management approach. Consensus of the Joint Committee of Italian Society of Otorhinolaryngology on biologics in rhinology

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous inflammatory condition of nasal mucosa and paranasal sinuses, predominantly mediated by type 2 inflammation and often associated with comorbid asthma and/or Exacerbated Respiratory Disease (N-ERD). The standard of care involves local and systemic corticosteroids and/or sinonasal surgery, although these options may be associated with recurrences and patients may require revision surgery. Difficult-to-treat patients, in fact, have a more severe disease requiring high systemic corticosteroid use and/or multiple sinonasal surgeries. Literature data suggests that biologic agents targeting specific key effectors of type 2 inflammation may offer supplemental therapy for patients with severe and uncontrolled CRSwNP, leading to significant improvement in several outcomes. For these reasons, over the years the endotyping of the disease has become increasingly important. Herein, we provide not only an update on the existing studies about the most promising biologics in CRSwNP, but also critical discussion on controversies about the use of biologics in severe uncontrolled CRSwNP. We finally provide consensus on strategic issues gathered among experts of the Joint Committee of Italian Society of Otorhinolaryngology on biologics in order to offer the best care for difficult to treat patients.
