Invasive fungal infections in patients with systemic lupus erythematosus: experience from affiliated hospitals of Catholic University of Korea.
The purpose of study was to determine the nature, outcomes and associated risk factors of invasive fungal infection (IFI) in patients with systemic lupus erythematosus (SLE), and compare the incidence of IFI in patients with rheumatoid arthritis (RA). A total of 1155 patients with SLE and 2004 patients with RA were retrospectively reviewed between 1992 and 2007. Twelve cases of IFI patients were identified in SLE patients (6 Aspergillus spp.; 5 Cryptococcus spp.; 1 Candida spp.). The incidence of IFI was significantly higher in patients with SLE than RA (1.04 vs. 0.15%). Among 12 patients with SLE, 10 had high Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores (>or=8). The most commonly involved organ was the lung (n = 6), followed by the meninges (n = 4). Most of SLE patients with IFI (91.7%) had taken steroids prior to IFI. Three SLE patients resulted in death. Notably, these patients were all infected with Aspergillus spp. The mortality was associated with the presence of leukopenia, high anti-DNA antibodies and high SLEDAI. Collectively, IFI is more common in patients with SLE than in patients with RA. High disease activity in patients with SLE might contribute to increased risk of IFI. In addition, mortality was associated with aspergillus infection, leukopenia and high anti-DNA antibodies.
