Abstract
Objective
We aimed to identify the predictive factors of hospital-acquired bacterial infections in patients with systemic lupus erythematosus (SLE).
Methods
This chart review study included patients with SLE who were hospitalized between 2009 and 2020 for reasons other than infection. The outcome was defined as any infection confirmed using any bacterial isolation method or diagnosed by treating physicians and required treatment with intravenous antibiotics. For statistical analysis, logistic regression analyses were performed.
Results
In total, 1678 patients (87.6% women) were included. The median age was 33 years (interquartile range, 24–47 years). The incidence of hospital-acquired infections was 13.9% (233 infections). Age, Systemic Lupus Erythematosus Disease Activity Index score, Systemic Lupus International Collaborating Clinics damage score, blood urea nitrogen and C-reactive protein levels, dosage of steroid in the previous month, recent use of 1 or more immunosuppressants, admission with a central venous catheter (or dialysis catheter), and use of central venous catheter or bladder catheter in the first 5 days were the predictive factors of nosocomial infections.
Conclusion
The patients' infection risk profile should be assessed to accurately determine the risk-benefit balance of any therapeutic intervention, minimize exposure to steroids and immunosuppressants, and maintain a low threshold for the early diagnosis of infections. Further studies should assess whether the modification of some identified factors could reduce the incidence of nosocomial infections.
