Introduction: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and aspirin-exacerbated respiratory disease (AERD) have more severe sinus disease than those without AERD. CRSwNP associated with type 2 inflammation and AERD can be difficult to control with standard medical therapy and sinus surgery., Case Study: 74-year-old Japanese woman with chronic sinusitis since age 50 and asthma since age 60. At age 64, she began to experience asthma exacerbations and was started on short-term corticosteroid therapy with prednisolone. At age 70, she experienced urticaria, nasal congestion, and wheezing after taking an NSAID; based on an NSAID provocation test, we diagnosed the patient with AERD and CRSwNP. A diagnosis of severe eosinophilic chronic rhinosinusitis was also made based on the scoring system and algorithm used in the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis., Results: Treatment with benralizumab (30 mg), formoterol-fluticasone combination via pressurized metered inhaler (1000 μg), and leukotriene receptor antagonist improved the asthma symptoms and exacerbations so the short-term prednisolone was stopped; however, nasal congestion and olfactory dysfunction (hyposmia) persisted, and peripheral blood eosinophil count (peak, 1500 cells/μL) and fractional exhaled nitric oxide (peak, 42 ppb) became elevated. Swapping the benralizumab for monthly tezepelumab (210 mg) improved not only the asthma symptoms but also the nasal congestion, olfactory dysfunction, eosinophil count (<300 cells/μL), and fractional exhaled nitric oxide level [8ppb]., Conclusion: Changing from benralizumab to tezepelumab improved asthma symptoms, nasal obstruction, and olfactory dysfunction in elderly, female, Japanese patient with AERD and CRSwNP., Competing Interests: Have no conflicts of interest to disclose about this study., (© 2024 The Authors.)

Treating ocular involvement in eosinophilic granulomatosis with polyangiitis (EGPA) can be challenging. We present the case of a 37-year-old woman with EGPA who had severe bilateral visual field defects. Laboratory results showed leukocytosis (17,500 WBC/μL, 25.8 % eosinophils), negative MPO-ANCA titer, and elevated PR3-ANCA level (33.2 IU/mL). Diffusion-weighted MRI revealed bilateral hyperintense occipital lesions, which were more prominent on the left. Her therapy initially included a steroid pulse, followed by daily prednisolone, but her visual field defects remained refractory. The addition of intravenous cyclophosphamide (5 courses) and intravenous immunoglobulin decreased her optic neuropathy and resolved her visual field defects., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)
