Abstract
AIM: To investigate clinical and computed tomography (CT) findings of invasive pulmonary aspergillosis (IPA) in patients with systemic lupus erythematosus (SLE) and to explore the relationships of CT findings with clinical characteristics and outcomes. MATERIALS AND METHODS: Clinical and CT findings of 14 SLE patients with proven (n=4) and probable (n=10) IPA between January 2006 and April 2013 were reviewed retrospectively and related to patients' outcomes. RESULTS: All patients (mean age, 42.3 ± 15.1 years; 11 women, three men) had active SLE, prior corticosteroid, and/or immunosuppressive therapy. Dominant CT findings performed within 10 days of the clinical onset consisted of nodules/masses (100%, 14/14), consolidations (92.9%, 13/14), and ground-glass opacity (85.7%, 12/14). Bilateral, multilobar, and upper-lobe involvement was common. Regardless of dominant patterns, the halo, reversed halo, air-crescent, hypodense, and feeding vessel signs were found in 12 (85.7%), one (7.1%), three (21.3%), seven (50%), and seven (50%) patients, respectively. There was no significant difference in CT findings between the IPA alone (n=5) and co-infection (n=9) groups and between survived (n=4) and non-survived (n=10) patients. The IPA-alone group more frequently had alcohol consumption (p=0.018), haemoptysis (p=0.023), and disseminated aspergillosis (p=0.027) than did the co-infection group. Non-survived patients tended to be older and have a history of recent hospitalisation. CONCLUSIONS: IPA is a rare, life-threatening disease affecting SLE patients in the early course of disease with high disease activity requiring corticosteroid and/or immunosuppressive therapy. Dominant CT findings are characteristics of angio-invasive form with a high frequency of the halo sign and bilateral, multilobar, and upper-lobe involvement.
