Project description:ObjectiveChronic rhinosinusitis with nasal polyps (CRSwNP) is a common and heterogeneous inflammatory condition, for which the drivers of the underlying inflammation are not yet fully understood. The use of biologic therapies to target specifically relevant effector cells or cytokines in CRSwNP is a growing field of interest. The objectives of this review are to provide an update on the existing studies of biologics in CRSwNP and to identify potential future areas for further research.Data sourcesAn initial literature review of biologic therapies in CRS was performed through publications gathered from a PubMed search for title/abstract containing "biologic" and "chronic rhinosinusitis." Further manuscripts describing scientific premise for each biologic were then reviewed.Study selectionsA detailed review of all studies describing biologic therapies targeting inflammation in CRSwNP was performed.ResultsBiologic therapies targeting interleukin (IL)-4Rα, IL-5, IL-5Rα, IL-33, immunoglobulin (Ig)E, and thymic stromal lymphopoietin (TSLP) have all been developed and have been investigated for treatment in CRSwNP, or current research suggests that they may have utility in this area. Only dupilumab, which inhibits IL-4Rα, has gained Food and Drug Administration approval for the treatment of adults with inadequately controlled CRSwNP.ConclusionRecent advances in our understanding of the fundamental drivers of the chronic respiratory inflammation in CRSwNP has led to the identification of several potential therapeutic targets for this disease. Future clinical success will rely on the availability of biomarker-based endotyping and responder analyses so that clinicians can precisely match each patient to the appropriate biologic, thereby optimizing the proper treatment strategy.

Project description:Persistent mucosal inflammation and microbial infection are characteristic of Chronic Rhinosinusitis (CRS). Though mucosal microbiota dysbiosis is a characteristic feature of other chronic inflammatory diseases, the relationship between sinus microbiota composition and CRS is unknown. Here we demonstrate, using comparative microbiome profiling of a cohort of CRS patients and healthy subjects, that the sinus microbiota of CRS patients exhibit significantly reduced bacterial diversity. Characteristic of this community collapse is the depletion of multiple, phylogenetically distinct, Lactic Acid Bacteria and the concomitant increase in relative abundance of a single species, Corynebacterium tuberculostearicum. Recapitulating the conditions observed in our human cohort in a murine model confirmed the pathogenic potential of C. tuberculostearicum and the critical necessity for a replete mucosal microbiota to protect against this species. Moreover, we provide evidence that Lactobacillus sakei, identified from our comparative microbiome analyses as a potentially protective species, affords defense against C. tuberculostearicum sinus infection, even in the context of a depleted sinus bacterial community. These studies demonstrate that sinus mucosal health is highly dependent on the composition of the resident microbiota, and identifies a new sino-pathogen and a strong bacterial candidate for therapeutic intervention. A total of 14 samples were profiled for microbiome composition: 7 from non-sinusitis patients, and 7 from patients with clinically diagnosed chronic sinusitis.

Project description:Chronic rhinosinusitis (CRS) with nasal polyps is a particularly challenging form of chronic rhinosinusitis in several ways. Patients have significantly more severe symptom burden and worse quality of life than patients with chronic rhinosinusitis without nasal polyps. Many patients return to the health care providers with persistent symptoms after repeated medical and surgical treatment. Patients have usually tried several different types of treatments, ranging from less invasive procedures to extensive surgical treatment. The surgical treatment is often repeated several times. The most common surgical treatment is functional endoscopic sinus surgery, another established procedure is Vidian neurectomy.
The main object of this pilot study is to investigate the safety of onabotulinumtoxin A towards the sphenopalatine ganglion (SPG) in CRS patients with nasal polyps. Efficacy data will also be collected to provide indication on whether future placebo-controlled studies should be performed.
Onabotulinumtoxin A inhibits the secretion of acetylcholine, blocking the parasympathetic reflex cascade in the SPG. As a result, the investigators expect less mucosal swelling, secretion and nasal polyps. The duration of such a blockade is believed to last for 3-9 months and will not lead to damage of the nerve.
This study opens up for improved treatment with less complications.

Project description:Purpose of reviewChronic rhinosinusitis with nasal polyposis (CRSwNP) is a phenotypic designation of the broader condition of chronic rhinosinusitis. The advent of targeted biologics has shown promise in targeting different aspects of the inflammatory pathway, yet there remains a lack of consensus on the correct timing and use of these medications. This review seeks to provide a concise update of the available literature on the pathophysiology of CRSwNP, the evolution and cost utility of biologics as it pertains to management of patients with CRSwNP, and evidence for each available biologic and its use in CRSwNP.Recent findingsThere are two biologics with FDA approval for use in CRSwNP: dupilumab and omalizumab. Recent clinical trials of other biologic therapies targeting type 2 inflammatory pathways have also demonstrated efficacy both in symptom scores and nasal polyp reduction. However, studies have questioned the cost utility of these medications compared to other interventions. Furthermore, timing of use with respect to other interventions including surgery remains challenging.

Project description:Patients with chronic rhinosinusitis (CRS) have abnormal immune responses triggered by a variety of infectious agents, airborne toxins and fungi. Respiratory epithelial cells serve as relay stations capable of amplifying or augmenting cues received from external stimuli to nearby immune cells located in the sinus mucosa. Previous studies have identified increases in complement components and complement gene expression in the mucosa of patients with atopic CRS with nasal polyps (CRSwNP). As part of a larger study, we used shotgun proteomics to quantify changes in mucus proteins between patients with and without nasal polyps.

Project description:The study should create data for the selection of a clinically relevant primary endpoint to assess the efficacy and safety of Buparid/PARI SINUS as compared to Budes Nasal Spray in the therapy of chronic rhinosinusitis (CRS) with polyposis nasi in adult patients. Ideally, the selected parameter should allow a correlation between an objective methodology and the clinical outcome of the study patients.

Project description:IntroductionFew studies assess biologicals such as, omalizumab, mepolizumab, benralizumab, and dupilumab in patients suffering from chronic rhinosinusitis with nasal polyposis (CRSwNP). The reported success rate in these studies differ, and it remains uncertain if there are any biomarkers to predict successful therapy. Our aim was to analyze the therapeutic outcome in a real life setting and to identify predictive biomarkers for successful treatment.MethodsData from patients with CRSwNP treated with a monoclonal antibody between November 2014 and January 2020 were analyzed retrospectively. Improvement in the polyp score and clinical symptoms like nasal obstruction, sense of smell, nasal discharge, and facial pain were evaluated. Other characteristics, including use of nasal or systemic steroids, comorbidities, previous history of sinus surgery, eosinophilia tissue, blood values (eosinophils, total immunoglobulin E, eosinophilic cationic protein, and interleukin 5), and allergic sensitization in serum were also investigated to identify possible predictive biomarkers.ResultsForty-eight treatments in 29 patients (m/f = 15/14) aged 27-70 years were reviewed. Treatments with mepolizumab showed the best success rates (78.9%), followed by omalizumab (50%) and benralizumab treatments (50%). However, a correlation between biomarkers and treatment success could not be found.Discussion/conclusionTreatment of CRSwNP with biologicals is a promising option for severe cases not responding to conventional therapy, including difficult-to-treat patients. Predictive biomarkers for a successful treatment could not be identified, but the reduction of eosinophilic cationic protein was linked with the response.
