RESUMEN
BACKGROUND: Research on the immune mechanism behind chronic rhinosinusitis (CRS) has revealed various new endotypes, leading to targeted therapies, especially for severe uncontrolled CRS. Biologics are novel therapeutic strategies providing targeted treatment for the difficult-to-treat recalcitrant CRSwNP patients. Dupilumab is a fully human-derived monoclonal antibody that binds to IL4Rα, inhibiting the signalling of both IL-4 and IL-13. In Hungary, it is approved for the treatment of uncontrolled CRSwNP according to criteria based on the EPOS2020 and the Hungarian guidelines. METHODOLOGY: This study aimed to collect and evaluate real-world therapeutic data of CRSwNP patients treated with dupilumab. One hundred thirty-five patients from eight different referral centres have been enrolled in this study, who received dupilumab since 2020. All subjects were adult patients (over 18 years) with uncontrolled CRSwNP. Baseline data collection included demographics, medical history, previous surgeries, related comorbidities, total endoscopic nasal polyp score (NPS), SNOT22, nasal congestion parameters measured with visual analogue scale (VAS) and nasal obstruction evaluation scale (NOSE), loss of smell score (LSS) and eosinophil count. 300 mg dupilumab was administered subcutaneously every second week. Follow up visits were performed after 6 and 12 months. RESULTS: After 6 and 12 months of treatment significant improvement was detected in all clinical parameters. Safety was proved, no severe side effects occurred, and no rescue treatment was necessary. CONCLUSIONS: Our real-life findings show that continuous dupilumab treatment is effective and safe in daily clinical practice in CRSwNP and other type 2 comorbidities such as bronchial asthma and NERD.
RESUMEN
PURPOSE: Our aim was to determine whether perioperatively administered corticosteroid treatment has any beneficial effect on the outcome of stapes surgery, with special regard to the audiological results and early postoperative morbidity. METHODS: 84 CO2 laser stapedotomies performed in our institute between 2013 and 2018 were included in our investigation. All cases underwent preoperative and mid-term postoperative pure-tone audiometric evaluation. Vestibular complications were also evaluated. The cases were subdivided into two groups, 23 patients received perioperative i.v. methylprednisolone treatment ("S") while the other 61 patients ("nS") did not receive any adjuvant pharmacological therapy. The data were analyzed retrospectively using IBM SPSS Statistics. RESULTS: CO2 laser stapedotomy proved to be a successful intervention with a significant improvement in ABG and AC thresholds as well. Long-term BC levels were significantly better compared to preoperative ones in the S group; however, in the nS group, no difference could be shown. Hearing and ABG gain were significantly superior in group S [28.1 dB (SD11.2) vs. 18.1 dB (SD 10.9) and 23.9 dB(SD 9.8) vs. 17.2 dB (SD 9.5), respectively]. CONCLUSION: No significant inner ear damage was detectable in the results of our CO2 laser stapedotomy method; however, the positive effect of corticosteroid treatment could be demonstrated through the postoperative hearing levels. We found no statistical difference in early postoperative morbidity. According to our data, the routine administration of corticosteroids during stapes surgery could be an issue worthy of consideration. The effects of perioperative treatment vs that on the first day after surgery, and topical vs. systemic treatment could be the subject of further investigation in a prospective manner.
