Systematic literature review of the epidemiology and clinical burden of chronic rhinosinusitis with nasal polyposis.

Conclusions: CRSwNP is fairly prevalent in the general population. Despite the significant efficacy of existing treatments, several unmet needs remain. The high burden of uncontrolled symptoms, frequent recurrence of nasal polyps after surgery, and long-term adverse effects of oral corticosteroids indicate that new therapies addressing these unmet needs should be developed. Although data on biologics from randomized controlled trials look promising, the efficacy of biologics in the real world has yet to be established.The SLR of the epidemiology and clinical burden of CRSwNP revealed key gaps in the literature. There was a paucity of prevalence data across many geographic areas, and no prevalence projections could be determined. Studies showed varying efficacy of non-biologics and no studies directly compared biologics for efficacy. Data regarding clinical efficacy of agents for eCRSwNP or severe CRSwNP were lacking, and these patient populations would be served by more trials. PMID: 32847417 [PubMed - as supplied by publisher]

Abstract BACKGROUND: Nasal nitric oxide(nNO) is considered a biomarker of nasal inflammation. OBJECTIVE: To perform a systematic review with meta-analysis and meta-regressions on the association between nNO levels and allergic rhinitis (AR). METHODS: PubMed, Web of Science, Scopus and EMBASE databases were systematically searched. Differences between cases and controls were expressed as standardized mean difference (SMD) with 95% confidence intervals (95%CI). RESULTS: Thirty nine articles were selected: 30 containing data on nNO measured by nasal aspiration (1,881 AR patients and 1,337 controls), an...

This article reviews the similarities and differences between pediatric and adult CRS.Recent FindingsRhinosinusitis is an inflammatory disease of the nose and the paranasal sinuses. In adults, inflammation in CRS without polyps (CRSsNP) mainly manifests with T-helper 1 lymphocytes while in CRS with polyps (CRSwNP) manifests with T-helper 2 lymphocytes and eosinophilic inflammation. In children, CRS inflammation manifests with neutrophils, macrophages, and lymphocytes. The associations between the ostiomeatal complex occlusion and CRS are revealed in adults but are not so evident in children. Although the relationship betwe...

Severe asthma is a high-burden disease. Real-world data on mepolizumab in patients with severe eosinophilic asthma is needed to assess whether the data from randomised controlled trials are applicable in a broader population. The Australian Mepolizumab Registry (AMR) was established with an aim to assess the use, effectiveness and safety of mepolizumab for severe eosinophilic asthma in Australia. Patients (n=309) with severe eosinophilic asthma (median age 60 years, 58% female) commenced mepolizumab. They had poor symptom control (median Asthma Control Questionnaire (ACQ)-5 score of 3.4), frequent exacerbations (media...

Atopic dermatitis (AD) is a chronic inflammatory skin disease commonly associated with other atopic conditions such as allergic rhinitis (AR). Dupilumab is approved in the USA for adults and adolescents with inadequately controlled moderate-to-severe AD; as an add-on maintenance treatment for adults and adolescents with inadequately controlled eosinophilic/oral corticosteroid-dependent asthma; and as an add-on maintenance treatment in adults with inadequately controlled chronic rhinosinusitis with nasal polyps.

ConclusionEosinophilic CRSwNP, which was previously a minor subtype in East Asians, has increased remarkably in incidence to become the predominant CRSwNP subtype in Beijing, China, indicating that rhinologists should place greater emphasis on its diagnosis and treatment.

AbstractPurpose of ReviewExogenously administered corticosteroids are widely used today in the field of rhinology. Allergic rhinitis (AR), non-allergic rhinitis (NAR), acute rhinosinusitis (ARS), chronic rhinosinusitis with (CRSwNP) and without (CRSsNP) nasal polyps, and autoimmune disorders with nasal manifestations are common diseases treated effectively with intranasal and oral glucocorticoids. We focus on physiological pathways, therapeutic benefits, indications, contra-indications, and side effects of glucocorticoid utilization in the treatment of rhinologic disorders such as AR, NAR, ARS, CRSsNP, and CRSwNP.Recent Fi...

Abstract Leukotrienes (LTs) are a family of inflammatory mediators including LTA4, LTB4, LTC4, LTD4, and LTE4. By competitive binding to the cysteinyl LT1 (CysLT1) receptor, LT receptor antagonist drugs, such as montelukast, zafirlukast, and pranlukast, block the effects of CysLTs, improving the symptoms of some chronic respiratory diseases, particularly bronchial asthma and allergic rhinitis. We reviewed the efficacy of antileukotrienes in upper airway inflammatory diseases. An update on the use of antileukotrienes in upper airway diseases in children and adults is presented with a detailed literature survey. Da...

CONCLUSIONS: NP is a chronic inflammatory disease that generates considerable use of health care resources. The close association with atopy, asthma, and NSAID hypersensitivity highlights the usefulness of an allergy workup in all patients with NP. Analysis of the clinical management of NP by allergists in Spain revealed a high degree of compliance with EPOS diagnostic and therapeutic recommendations. PMID: 26310042 [PubMed - in process]
