A Case of Acinetobacter junii Cavitary Pneumonia With Bacteremia in a Patient With Systemic Lupus Erythematosus

Acinetobacter genus includes multiple species, most notably A. baumanii that constitutes a common cause of nosocomial infections worldwide, particularly in patients with underlying immunodeficiency and risk factors (e.g., prior broad-spectrum antibiotic therapy, central venous catheter, mechanical ventilation). A. junii is a very rare human pathogen that is particularly associated with outbreaks of sepsis in immunocompromised neonates and pediatric oncology patients and rarely in immunocompromised adults. To our knowledge, this is the first case report of cavitary pneumonia with bacteremia secondary to A. junii in a patient with systemic lupus erythematosus (SLE).
