Objectives
Systemic rheumatic diseases (SRDs) are a group of inflammatory disorders that can need intensive care unit (ICU) admission during a flare-up, requiring administration of immunosuppressants. We undertook this study to determine the frequency, outcome, and occurrence associated factors of infections in flare-up SRD patients receiving immunosuppressant.
Methods
Monocenter, a retrospective study including SRD patients admitted to ICU for a flare-up requiring immunosuppressant from 2004 to 2019. The primary endpoint was in-ICU-acquired infections.
Results
Ninety-eight patients (female/male ratio: 1.6; mean age at admission: 39.5 ± 17.4 years) were admitted to the ICU for a SRD flare-up, inaugural in 61.2% cases. A specific treatment was given to every patient: corticosteroids 100%, cyclophosphamide 45.9%, plasma exchange 46.9%. Ninety-five infections occurred in 35 (36%) patients mainly pneumonias. The overall in-hospital mortality was 17.3%, and 46% of patients with a nosocomial infection died during their ICU stay. The logistic regression multivariable model retained renal replacement therapy and mechanical ventilation as independent predictors of infection.
Conclusion
In-ICU-acquired infection in SRD flare-up is a frequent event associated with organ failures but not with in-ICU use of immunosuppressants. These data suggest that the fear of infection should not withhold a careful in-ICU use of immunosuppressive drugs.
Key Points • In-ICU infections are frequent in flare-up systemic rheumatic disease patients. • Infections are associated with increased mortality. • Cyclophosphamide given in ICU was not independently associated with infection. • Severe neutropenia occurred in 27% of patients receiving cyclophosphamide in ICU. |
