Infections in systemic lupus erythematosus
Abstract:
A prospective study was carried out on the occurrence of infections in 28 hospitalised systemic lupus erythematosus (SLE) patients. In 38 episodes of infections, 23 were bacterial (60.5%), 4 were viral (10.6%) and culture negative infections were present in 10 (26.3%). The most common isolated organisms were Staphylococcus aureus (30.4%), Salmonella species (21.7%), Pseudomonas species (13.0%), and Klebsiella species (13.0%). The care rate was 94.7%. Death occurred in 2 patients. Lupus activity, impaired renal function, and cytotoxic therapy did not predispose to infection.
Insights
Bacterial infections are common in hospitalized systemic lupus erythematosus (SLE) patients, with Staphylococcus aureus being a frequent cause. However, lupus activity or treatments did not increase infection risk.
Area of Science:
- Infectious Diseases
- Rheumatology
- Clinical Microbiology
Background:
- Systemic lupus erythematosus (SLE) is an autoimmune disease associated with increased infection risk.
- Understanding infection patterns in hospitalized SLE patients is crucial for effective management.
Purpose of the Study:
- To investigate the incidence and types of infections in hospitalized patients with systemic lupus erythematosus.
- To identify common pathogens and assess risk factors for infection in this population.
Main Methods:
- Prospective study design.
- Inclusion of 28 hospitalized systemic lupus erythematosus patients.
- Detailed monitoring of infection episodes, pathogen identification, and clinical outcomes.
Main Results:
- 23 bacterial, 4 viral, and 10 culture-negative infections occurred in 38 episodes.
- Staphylococcus aureus, Salmonella, Pseudomonas, and Klebsiella were the most common pathogens.
- A high care rate of 94.7% was observed, with 2 deaths.
Conclusions:
- Bacterial infections are predominant in hospitalized SLE patients.
- Lupus activity, renal impairment, and cytotoxic therapy were not found to be predisposing factors for infection in this cohort.
