Combination Biologic Therapy with Mepolizumab and Dupilumab for Severe Eosinophilic Granulomatosis with Polyangiitis and Chronic Rhinosinusitis with Nasal Polyp.

We report the case of a 55-year-old female with eosinophilic granulomatosis with polyangiitis and chronic rhinosinusitis with nasal polyp. Rhinosinusitis recurred 6 months after full-house endoscopic sinus surgery. Although conventional treatment with azathioprine and mepolizumab with steroids was given, it was difficult to simultaneously control both rhinosinusitis and eosinophilic granulomatosis with polyangiitis. Clinical examinations showed polyps in the olfactory cleft, and the patient's anosmia gradually became persistent. Even after administering mepolizumab for a certain period of time, symptoms did not improve, but when the biologic agent was switched to dupilumab, an improvement in recalcitrant chronic rhinosinusitis with nasal polyp was observed. While dupilumab was administered intermittently for refractory chronic rhinosinusitis with nasal polyp, the rhinosinusitis improved and symptoms such as worsening of eosinophilic granulomatosis with polyangiitis paresthesia were observed. Both symptoms gradually subsided 19 months after starting intermittent administration, leading to the discontinuation of dupilumab administration. Rhinosinusitis in the setting of eosinophilic granulomatosis with polyangiitis may be refractory in some cases, and this case provides findings demonstrating the strong effect of dupilumab on eosinophilic inflammation.

Invasive Fungal Rhinosinusitis with Orbital Apex Syndrome Leading to Brain Abscess in a Patient with Ulcerative Colitis.

We report the case of a 65-year-old male who presented with a 1-week history of right periorbital pain and progressive visual loss. He had a history of ulcerative colitis and was taking oral corticosteroids and mesalazine. Neurological and radiological examination demonstrated a rare case of invasive fungal rhinosinusitis that began with orbital apex syndrome. Initial endoscopic sinus surgery was performed and fungal culture identified Aspergillus fumigatus. Although antifungal treatment was started empirically before the operation, the patient had improved orbital pain but continued to have decreased right vision. Five months after the first surgical procedure, his condition deteriorated, including loss of consciousness, and a right temporal lobe abscess was found and surgically drained. Since then, the patient received antifungal treatment for 4 years without recurrence. Invasive fungal rhinosinusitis with orbital apex syndrome should be treated with long-term postoperative antifungal medication. It should be noted that even in immunosuppressive individuals such as ulcerative colitis, fungal rhinosinusitis with orbital apex syndrome may become severe.

Effect of fexofenadine/pseudoephedrine combination tablet on nasal obstruction in patients with allergic rhinitis using rhinomanometry: A randomized controlled trial.

BACKGROUND: A fexofenadine/pseudoephedrine combination tablet (F/P) is an optimal product for nasal obstruction. It contains fexofenadine hydrochloride, a histamine H1-receptor antagonist for sneezing and rhinorrhea and pseudoephedrine hydrochloride, an α-adrenergic agonist. The effect of an antihistamine-decongestant on nasal obstruction has been demonstrated in previous studies, but onset of action and efficacy data on nasal obstruction are limited. OBJECTIVE: We estimated the efficacy of F/P on nasal obstruction in patients with house dust mite-induced allergic rhinitis (AR) versus fexofenadine (F) using objective methods. METHODS: In this single-center, single-dose, prospective, randomized, parallel-group study, 24 adult patients with a history of at least 2 years of AR and nasal obstruction were randomized to receive F/P or F. The effect on nasal obstruction was evaluated using nasal airflow and visual analog scale (VAS) score measured at 30-minute intervals before and for 8 hours after dosing. The primary end point was onset of action, based on a comparison of absolute change from baseline in nasal airflow between F/P and F. The protocol was registered in a clinical trial registry as UMIN 000041845. RESULTS: The onset of action for F/P was 30 minutes based on nasal airflow and 60 minutes based on VAS. F/P maintained a significant beneficial effect after onset of effect, while F showed no significant change during the test period. CONCLUSIONS: We found F/P had a clear effect on nasal obstruction associated with perennial AR when compared with F. There was a time lag in nasal airflow improvement and nasal obstruction relief.
