Peripheral eosinophilia and eosinophilic colitis during long‐term azole therapy for pulmonary aspergillosis
Abstract
Introduction:
Voriconazole and posaconazole are often used to treat invasive Aspergillus infections. We describe a patient with chronic pulmonary aspergillosis (CPA) who experienced peripheral eosinophilia and eosinophilic colitis while on voriconazole, and also experienced gastrointestinal symptoms and recurrent eosinophilia while on subsequent posaconazole therapy.
Case presentation:
A 75‐year‐old female with recurrent pulmonary mucus plugs due to CPA was treated with long‐term oral voriconazole. The patient had no clinical evidence of CPA exacerbations while on such antifungal treatment but developed peripheral eosinophilia, diarrhoea and eosinophilic colitis after >5 years of voriconazole therapy that resolved after cessation of azole therapy. Due to a CPA exacerbation after stopping voriconazole, the patient was started on posaconazole as an alternative CPA therapy. However, after 15 months, the patient developed a recurrence of peripheral eosinophilia and diarrhoea while on posaconazole.
Conclusion:
Long‐term use of voriconazole and posaconazole can be used successfully to reduce the incidence of CPA exacerbations. However, such antifungal therapy may also lead to peripheral eosinophilia, diarrhoea and eosinophilic colitis.
