RESUMEN
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.
RESUMEN
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.
RESUMEN
INTRODUCTION: Many studies have reported a poor prognosis for eosinophilic granulomatosis with polyangiitis (EGPA) patients with cardiac involvement. CASE STUDY: A woman developed EGPA at 37 years of age, with weight loss, numbness in the right upper and lower extremities, muscle weakness, skin rash, abdominal pain, chest pain, an increased peripheral blood eosinophil count (4165/µL), and necrotizing vasculitis on peroneal nerve biopsy. The patient was treated with prednisolone, immunosuppressants, intravenous immune globulin, and mepolizumab, but she experienced many relapses, with chest pain, abdominal pain, numbness, and paralysis, over a long period. The patient died from aspiration pneumonia at 71 years of age after undergoing left total hip arthroplasty for left hip neck fracture. RESULTS: Autopsy showed bronchopneumonia in the lower lung lobes on both sides, as well as infiltration of inflammatory cells, including neutrophils and lymphocytes. There was no evidence of active vasculitis in either the lung or colon. At autopsy the heart showed predominantly subendocardial fibrosis and fatty infiltration, but no active vasculitis or eosinophilic infiltration. CONCLUSION: To our knowledge, there have been no autopsy reports of EGPA patients who have survived for 34 years with recurrent cardiac lesions. In this case, the cardiac involvement (active vasculitis and eosinophilic infiltration) had improved by the time of death.
