Case Report
Cardiogenic shock, asthma, and hypereosinophilia Abstract Eosinophilic granulomatosis with polyangiitis (EGPA) (formerly Churg-Strauss) is a multisystem syndrome associating asthma, hypereosinophilia, and signs of peripheral vasculitis. We report the case of a 21-year-old man admitted for cardiogenic shock revealing a severe left and right ventricular dysfunction. Hypereosinophilia, history of asthma, and peripheral neuropathy strongly suggested the diagnosis of EGPA. Cardiac magnetic resonance imaging confirmed heart involvement with a diffuse subendocardial late gadolinium enhancement. The patient was successfully treated with systemic corticosteroids, intravenous cyclophosphamide, and inotropes. At 6-month follow-up, the patient is doing well. Cardiac involvement is rare in EGPA and often carries poor prognosis. Specific early steroid therapy may improve hemodynamic at short term, allowing postponing the need for circulatory mechanical support or heart transplantation. A 21-year-old male patient was referred to our intensive care unit for cardiogenic shock. Transthoracic echocardiography displayed severe left ventricular (LV) and right ventricular (RV) dysfunctions (Video 1). Brain natriuretic peptide levels rose to 2072 ng/L and leukocyte count to 13 100/mm 3 with 4470/mm 3 (34.1%) eosinophil cells. Cardiac magnetic resonance imaging showed depressed LV and RV ejection fractions (EFs, 15% and 20%, respectively) with extensive biventricular subendocardial late gadolinium enhancement (LGE) and bilateral ventricular thrombi (Fig. 1A-C; Video 2). The patient was diagnosed with asthma 4 years ago and suffered for 1 month from
progressive painful mononeuropathy of the right peroneal nerve proved by electromyography. The association of asthma, hypereosinophilia, peripheral axonal neuropathy, and heart failure (HF) led to the diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) (formerly Churg-Strauss). Antineutrophil cytoplasmic antibodies (ANCAs) were negative. Patient's condition rapidly improved with high doses of corticosteroids (15 mg/kg per day for 3 days followed by 1 mg/kg per day) associated to intravenous cyclophosphamide (0.6 g/m2 at days 0, 15, and 30 followed by 0.7 g/m2 every 4 weeks for 4 months), allowing weaning inotropic support within 1 week. Cardiac magnetic resonance imaging performed at 1 month showed an improvement in LVEF (35%) and RVEF (37%), along with the disappearance of cardiac thrombi (Fig. 2 A-C; Video 3). At 6-month follow-up, the patient is doing well with a complete relief of neuropathic pain; LVEF is at 40% on transthoracic echocardiography (Video 4). The diagnosis of EGPA should be evoked in acute HF particularly when associated with recent asthma and hypereosinophilia, whereas histologic evidence of necrotizing vasculitis on tissue biopsies may be conclusive. The prevalence of this vasculitis is 7 to 13 cases per million inhabitants [1]. Circulating ANCAs with specificity for myeloperoxidase are of great interest for the diagnosis but are negative in almost 50% of cases. Heart involvement occurs in approximately 8% to 20% of EGPA patients and is more frequent in ANCA-negative patients (almost30% of patients with HF are ANCA positive). It often carries a poor prognosis [2]. Specific early steroid therapy may improve hemodynamic in the short term, allowing postponing the need for circulatory mechanical support or heart transplantation. For patients with refractory forms of EGPA, heart
