A Practical Clinical Protocol for Monitoring Patients with Severe Uncontrolled Chronic Rhinosinusitis with Nasal Polyposis Treated with Biologics.

OBJECTIVES: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a pathological condition which leads to high healthcare-related costs and low quality of life for patients. The introduction of new biological therapies (monoclonal antibodies, MAbs) in CRSwNP patients has allowed new therapeutic options for non-responders to conventional therapies and Dupilumab represents the first approved biological agent. The aim of this paper is to provide a practical clinical multidisciplinary protocol which might help clinicians involved in this field to monitor the clinical outcomes. METHODS: Our centre of Rhinology and Rhino-Allergology has developed a dedicated collection form to observe the outcomes of patients treated with Dupilumab. Our research started from the indications given in EPOS 2020 as main reference. We then implemented these references in an electronic database trying to apply Evidence Based Medicine (EBM) in current clinical practice. RESULTS: The result consists of three parts: an anamnestic collection data, a clinician reported outcome and two patient reported outcomes (PROMs) questionnaire, the visual analogue scale (VAS) and the Sino-Nasal Outcome Test-22 (SNOT-22). The tables we propose should provide an adequate correlation with the patients' adherence to therapy and their treatment outcomes. Such periodical evaluation (after a month, after 3 months, after 6 months and at one year) should quickly allow to monitor if the patient is correctly assuming the therapy and the eventual objective improvements. CONCLUSIONS: We propose a practical monitoring protocol formulated to analyse both objective and subjective aspects of patients with severe uncontrolled CRSwNP treated with MAbs, thus helping to define in future a better comparison between the clinical results of different institutes.

Latex allergy desensitization by exposure protocol: five case reports.

UNLABELLED: Two clinical reports dealing with subcutaneous desensitization to latex are available, but these treatments were reported to have significant side effects. To investigate an alternative method for latex desensitization, we present five cases of immunoglobulin E-mediated latex allergy in which a specific desensitization was successfully performed by means of an original exposure protocol. Five female patients with proven latex allergy underwent an original contact desensitization by wearing latex gloves daily, progressively increasing exposure to latex. All patients reached a final latex exposure time of 60 min in both hands. The desensitization protocol was completely successful in all patients. Twelve months after the beginning of the desensitization program, all the treated subjects were able to wear latex gloves daily without any clinical manifestations. This study provides evidence that a successful contact desensitization to latex is possible with no side effects. The adopted exposure protocol seems to be completely safe and effective. However, further studies in larger groups of subjects are necessary to fully confirm these preliminary results. IMPLICATIONS: We present five patients with latex allergy who underwent desensitization by a new cutaneous exposure protocol. This study provides evidence that a safe therapeutic approach to latex allergy is possible.
