Mepolizumab in the Treatment of Patients With Severe Uncontrolled CRSwNP: a Multicentric Real Life Observational Study

MEPOREAL
Start date: February 5, 2024
Phase:
Study type: Observational

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a complex chronic inflammatory disease of the nasosinusal mucosa that has a significant negative impact on patients' quality of life. In CRSwNP, chronic inflammation is primarily driven by type 2 pro-inflammatory interleukins (ILs )such as IL-5, IL-4, and IL-13 along- side high levels of eosinophils in the surrounding tissue. Mepolizumab is a targeted, humanized anti-IL-5 antibody that prevents IL-5 from binding to its receptor on eosinophils and selectively inhibits eosinophilic inflammation. So far, randomized clinical trials have assessed efficacy and safety of Mepolizumab in a large number of patients, whereas evidences in real life clinical practice are limited to few monocentric series. Herewith, we present a multicenter, observational, prospective/retrospective nationwide real-life study with the aim to confirm the effectiveness and the safety of Mepolizumab over the first year of treatment in a real life setting. The primary objective of this study is to evaluate the reduction of dimension of nasal polyps and the improvement of quality of life in the patient measured through symptomatologic questionnaires. The secondary objective is to evaluate improvements in terms of smell dysfunction, comorbidities, biomarkers (nasal cytology and blood eosinophilia), need of surgery or systemic steroids.

Correlation Between the Microbiome and Type 2 Inflammatory Diseases of CRSwNP

Start date: January 22, 2024
Phase:
Study type: Observational

Nasal microorganisms, exfoliated cells, nasal secretions, fetal microorganisms and blood were collected from patients with chronic sinusitis with nasal polyps before medication. Nasal polyp tissues of the patients were clamped for pathologic biopsy in the outpatient clinic. Methylprednisolone was then administered to the patients for 17 days, and the nasal microbial changes were observed after the administration of the drug. Patients underwent surgical treatment after the administration of the drug, and postoperative patients were followed up for a long period of time until polyp recurrence. During the follow-up, the microorganisms in the patients' postoperative nasal cavities were collected and the postoperative microbial changes were recorded

Proof of Concept of Remote Management of Chronic Inflammatory Airway Diseases for Patient Empowerment

PRECISION
Start date: February 2024
Phase: N/A
Study type: Interventional

Chronic rhinosinusitis (CRS) is a multifactorial disease characterized by persistent symptomatic inflammation of the mucosa of the nose and paranasal sinuses, with (CRSwNP) or without (CRSsNP) the presence of nasal polyps. It affects 5 to 12% of the general population. CRS is often associated with asthma, which has a prevalence of 4% in the general population, reaching 30%-70% among patients with CRS. The current standard clinical evaluation of patients for both diseases has two main components: a subjective one (self-assessment provided by the patient), based mainly on the PROMs (Patient-Reported Outcome Measures) questionnaire, and an objective one (formulated by the clinician). Questionnaires present accuracy and response rate problems that have been investigated in the literature, finding that short questionnaires, incentives, personalization of questionnaires as well as repeat sending strategies or telephone reminders have a beneficial impact on the quantity and quality of responses. Today there are many new channels provided by technology. Among them, AI chatbots have been used in a variety of healthcare domains such as medical consultations, disease diagnosis, mental health support and, more recently, risk communications for the COVID-19 pandemic, and can offer a better way to collect questionnaires. At the same time, the recent technical solution of new non-invasive techniques for RFID radio frequency identification devices allows subjective reports to be accompanied with objective reports. The PRECISION project aims to evaluate systems for home monitoring of chronic rhinosinusitis (CRS) and asthma, two highly prevalent chronic diseases. The frequent association between the two pathological conditions is a further argument in support of the rationality of a common approach. As regards the collection of PROMs, three acquisition channels will be compared: i) AI Chatbots; ii) PhoneBot; iii) Mobile application. Data will be analyzed in relation to patient profiles to define the quality and quality of response. Regarding objective evaluation, the project will investigate the efficiency of objective remote airflow measurements for both upper (CRS) and lower (asthma) airways using dedicated non-invasive systems based on RFID technology.

Early-onset Dupilumab Effects in CRSwNP

Start date: January 1, 2024
Phase: Phase 4
Study type: Interventional

While we know that Dupilumab has profound effects in patients with CRSwNP, these are often seen months later after treatment initiation; however, in practice, patients often endorse feeling significantly better within days of their first injection. No studies have investigated the molecular basis for such an acute change. This study proposes that specific cytokine changes in phenotype in addition to microbiome and oscillometry effects play a synergistic role in producing this effect.

NCT ID: NCT06182982 Not yet recruiting - Anesthesia Clinical Trials

Auriculotherapy for Intraoperative Blood Pressure Control

AuriFESS
Start date: June 15, 2024
Phase: N/A
Study type: Interventional

The endoscopic surgery of the paranasal sinuses (FESS) requires careful control of arterial pressure to prevent bleeding of the nasal mucosa that may lead to a reduction in the visual field. However, controlled reversible hypotension has been associated with phenomena of peripheral hypoperfusion with possible organ damage on an ischemic basis. Based on the data available in the literature, a mean arterial pressure (MAP) target between 50 and 65 mmHg is considered acceptable. Although blood pressure control is generally ensured through intravenous pharmacological approaches, there is evidence of efficacy with the use of Auriculotherapy medical devices (stimulation of specific points in the ear through the application of Magnetic ball plasters). Proposed pharmacological choices to achieve this result have been multiple, although totally intravenous anesthesia with propofol and opioids seems to be more effective than balanced anesthesia with halogenated agents and opioids. However, this fundamental option requires the administration of antihypertensive drugs to achieve the blood pressure target. Despite common contraindications to individual pharmacological classes, various active principles have been compared. Among these, continuous low-dose nitroglycerin infusion has proven effective due to titratability linked to its short half-life, perioperative complications, and better conditions of peripheral perfusion compared to beta-blockers such as labetalol or esmolol. Based on existing literature data, in our hospital, general anesthesia is typically conducted with intravenous techniques and the continuous administration of low doses of nitroglycerin in continuous infusion (0.01-2 mcg/kg/min). Despite the low dosages, this drug can be burdened with dosage-dependent adverse effects such as orthostatic hypotension, tachycardia, or headache. To reduce the dosage of nitroglycerin, we have borrowed from different contexts hypotensive auriculotherapy techniques (stimulation of specific ear points through the application of magnetic ball plasters), which have proven effective in managing systemic pressure in patients with essential hypertension. These non-pharmacological techniques, already used during general anesthesia for the management of nausea and pain, could prove promising in reducing the use of antihypertensive drugs even in the intraoperative context. The primary hypothesis of our study is that the use of Auriculotherapy medical devices is effective in achieving a hypotensive effect in patients undergoing general anesthesia during FESS surgery.

3D Printing to Improve Nasal Irrigation Outcome

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

Three-dimensional (3D) printing has been an emerging technology with uses in a wide array of fields. This research aims to use 3D printing as a tool to provide personalized education to maximize treatment efficacy based on the patient's individual anatomy. With increased irrigation to the sinuses, we hypothesize there will be improved patient satisfaction and higher quality of life. The outcomes of this research could lead to a new option for patients who live with chronic rhinosinusitis are not candidates for surgery or are interested in less invasive options. The 3D printed nasal replica is not something that would be implanted, rather it is a hand-held device used specifically for participants to better understand their nasal anatomy.

th2 Modulation CRSwNP

Start date: January 1, 2024
Phase: Phase 4
Study type: Interventional

Chronic rhinosinusitis (CRS) is a condition of persistent sinonasal mucosal inflammation which affects 11.9% of the US population. Mepolizumab is newly approved to treat chronic rhinosinusitis with nasal polyps (CRSwNP, the spaces inside nose and head are swollen and inflamed) and acts booking interleukin-5 (IL-5) a protein implicated in the inflammatory process. We aim to use Single-cell RNA sequencing (RNA-Seq, a method of genetically 'barcoding' cells to allow gene expression to be profiled at the level of individual cells) to study the effects of IL-5 blockade on the generation and maintenance of nasal adaptive immune responses, in CRS subjects.
