Chronic Eosinophilic Pneumonia as the Initial Manifestation of Rheumatoid Arthritis: A Case Report
Abstract
Chronic eosinophilic pneumonia (CEP) is a rare disorder characterized by peripheral blood eosinophilia, increased eosinophils in bronchoalveolar lavage fluid, and eosinophilic infiltration of lung alveoli and interstitia. While only a handful of cases of CEP have been reported in rheumatoid arthritis (RA), CEP as the initial presenting manifestation of RA is extremely rare. We report a 28-year-old woman who was diagnosed with CEP in association with newly diagnosed RA, who responded to corticosteroid therapy but relapsed on steroid taper. She was later treated with mepolizumab as a steroid-sparing agent while being tapered off steroids.
