Overwhelming pneumococcal bacteraemia in systemic lupus erythematosus
Annals of the Rheumatic Diseases
|April 1, 1989
Summary
A young woman with undiagnosed systemic lupus erythematosus (SLE) died from pneumococcal infection. This case highlights severe immune dysfunction in SLE, even without immunosuppressive treatment, and discusses Fc receptor dysfunction.
Area of Science:
- Immunology
- Infectious Diseases
- Rheumatology
Background:
- Encapsulated bacterial infections, such as pneumococcal disease, can be severe in individuals with compromised immune systems.
- Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organ systems and impair immune function.
Observation:
- An 18-year-old woman presented with fulminant pneumococcal bacteraemia, leading to multisystem organ failure and death.
- Pre-existing conditions predisposing to overwhelming bacterial infections were investigated and found negative, except for newly diagnosed systemic lupus erythematosus (SLE).
Findings:
- The case underscores the potential severity of immune system dysfunction in SLE patients, irrespective of immunosuppressive therapy.
- Fc receptor dysfunction is proposed as a potential mechanism linking SLE and increased susceptibility to pneumococcal bacteraemia.
Implications:
- This case emphasizes the critical need for early diagnosis and management of SLE to prevent severe infectious complications.
- Further research into Fc receptor function in SLE may reveal novel therapeutic targets for preventing invasive bacterial infections.
