Allergies, Author Interviews, ENT / 07.10.2020 Interview with: Brent A. Senior, MD, FACS, FARS Professor of Otolaryngology/Neurosurgery Vice Chairman for Clinical Affairs Nathaniel and Sheila Harris Distinguished Professor Chief, Division of Rhinology, Allergy, and Endoscopic Skull Base Surgery Department of Otolaryngology-Head and Neck Surgery University of North Carolina at Chapel Hill Chapel Hill, NC What is the background for this study? How common is the problem of chronic rhinosinusitis with nasal polyps? Response: Chronic rhinosinusitis (CRS) is a very common illness in the United States and around the world, estimated to impact 2-14% of the US population. Chronic rhinosinusitis with polyps is a particularly challenging form of the disease marked by significant impact on quality of life, and being challenging to treat with significant recurrences of symptoms despite standard medical and surgical treatment. Inhaled intranasal steroids are standard therapy for patients with CRS including those with nasal polyps. However, many patients continue to have significant nasal symptoms despite treatment with these medications. This study was designed to answer the question of whether patients who had been receiving treatment with inhaled intranasal steroids and failed were improved by using EDS-FLU. Results were obtained by pooling data from two previous studies of the use of EDS-FLU in patients with CRS, called Navigate 1 and 2.   (more…)
Author Interviews, CDC, Infections, JAMA / 26.03.2018 Interview with: Dr. Katherine Fleming-Dutra, MD, senior author Deputy Director Office of Antibiotic Stewardship CDC What is the background for this study? What are the main findings? Response: As noted in a previous study, antibiotics are prescribed more for sinus infections than any other illness in the United States. We found that almost 70% of antibiotic prescriptions were for 10 days or longer, whereas 5-7 days is recommended for most patients when antibiotics are needed. In addition, more than 20% of antibiotic prescriptions for sinus infections were for 5 days of azithromycin, even though guidelines recommend against prescribing azithromycin for sinus infections.

Allergies, Asthma, Author Interviews, JAMA / 04.02.2016 Interview with: Prof Dr. Dr. h.c. Claus Bachert Head Upper Airways Research Laboratory (URL) Chief of Clinics ENT-Department University Hospital Ghent Ghent, Belgium Medical Research: What is the background for this study? What are the main findings? Prof. Bachert: Chronic sinusitis with nasal polyposis represents mucosal inflammation, and polyps in the nasal cavity and sinuses, which result in long-term symptoms of nasal obstruction and congestion, reduction in or loss of sense of smell, and loss of quality of life. Patients with nasal obstruction or congestion have a two-fold higher risk of sleep dysfunction, increased fatigue, and decreased work productivity. About 40 percent of chronic sinusitis with nasal polyps patients develop asthma, which often is non-allergic late-onset disease. Treatment options consist of nasal and systemic glucocorticosteroids; long-term or repeated treatment with oral GCS carries a great risk of side effects in these patients. Surgery of the sinuses is another option, but recurrence of polyps is frequent. Further treatment options are highly needed. About 85% of nasal polyps represent a type 2 inflammation, with increased eosinophils and IgE formation. Dupilumab is an investigational therapy that inhibits signaling of IL-4 and IL-13, two key cytokines required for type 2 (Th2) immune responses. Dupilumab has been successfully administered in patients with asthma and atopic dermatitis. The current randomized, double-blind, placebo-controlled group study enrolled 60 adult patients with chronic sinusitis with nasal polyposis refractory to intranasal corticosteroids at 13 sites in the United States and Europe. Following four weeks of mometasone furoate nasal spray (MFNS) run-in, patients in the study received 300 milligrams (mg) of dupilumab or placebo once per week subcutaneously for 16 weeks, after an initial loading dose of 600 mg. All patients in the study continued to receive daily MFNS. Eligible patients had bilateral nasal polyposis and showed chronic symptoms of sinusitis, despite treatment with an intranasal corticosteroid for at least two months. Fifty-eight percent of patients in the study had received prior nasal surgery for their condition.  ​ We found that dupilumab treatment was associated with significant improvements in endoscopic, clinical, radiographic, and pharmacodynamic end points after 16 weeks. Significant improvements in quality of life and in major symptoms, such as sense of smell, nasal congestion, and nocturnal awakenings,were reported. In those patients with asthma, also lung function and asthma control were significantly better with Dupilumab compared to placebo. Dupilumab was generally well tolerated, and no serious adverse events were considered to be related to dupilumab.​ (more…)

Vijay R. Ramakrishnan, MD Assistant Professor University of Colorado Department of Otolaryngology Aurora, CO Interview with: Vijay R. Ramakrishnan, MD Assistant Professor University of Colorado Department of Otolaryngology Aurora, CO 80045 Medical Research: What is the background for this study? What are the main findings? Dr. Ramakrishnan: Chronic rhinosinusitis (CRS) is an extremely common problem, associated with major quality of life alterations and financial burden. Bacteria are thought to play a role in the initiation or sustenance of the disease, at least in a subset of CRS patients. Chronic rhinosinusitis is probably a group of heterogeneous diseases with different pathways that result in the same endpoint. Here, we study the bacterial microbiome of a large group of CRS and healthy sinuses, and discover that a few clinical subtypes display unique bacterial microbiome profiles and that the microbiome may predict outcomes from severe Chronic rhinosinusitis patients electing to undergo surgery.
