Pulmonary embolism and deep vein thrombosis in eosinophilic granulomatosis with polyangiitis successfully treated with rivaroxaban

Publication date: 2018 Source:Respiratory Medicine Case Reports, Volume 25 Author(s): Tomoyuki Naito, Hiroki Hayashi, Takeru Kashiwada, Yoshinobu Saito, Shinji Abe, Kaoru Kubota, Akihiko Gemma A 41-year-old woman presented complaining of cough and purpura for one month. On her first visit, a blood test demonstrated peripheral blood eosinophilia, but chest radiography showed no abnormalities. However, 2 days after the first visit, she went to the emergency room because of fever and right-sided chest pain. Contrast-enhanced computed tomography of the chest showed pulmonary embolism and air space consolidation. Thrombosis was present in the popliteal vein. Bronchoscopy revealed alveolar hemorrhage and increased eosinophils in the bronchoalveolar lavage fluid, and a skin biopsy demonstrated a perivascular eosinophilic infiltrate. The patient was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). We started steroid therapy and low-molecular-weight heparin (LMWH). The chest pain and fever disappeared, and the peripheral eosinophil count normalized. However, the thrombosis in the leg worsened. It was dramatically improved by changing from LMWH to oral rivaroxaban. The thrombogenic risk of eosinophilia should be recognized. This case suggests that oral rivaroxaban is useful when thrombosis is uncontrolled by LMWH in a patient with EGPA.
