Septic shock secondary to an acute necrotizing community-acquired pneumonia with bacteremia due to Pseudomonas aeruginosa. (2019) - Riviere, P.
Highlights: Necrotizing acute community-acquired pneumonia due to Pseudomonas aeruginosa are rare. Second description of a septic shock secondary to a necrotizing CAP with bacteremia due to P. aeruginosa for which pulmonary origin was proven by bronchoalveolar lavage fluid on a patient who survived. Anti-pseudomonal monotherapy may be may be a better option for older patients Despite risk factors related to the host or to the bacteria, the evolution remains unpredictable. Abstract: Pseudomonas aeruginosa is an uncommon cause of necrotizing acute community-acquired pneumonia (CAP). Only thirteen cases have been previously reported in the literature. In this article, we describe a case of previously healthy 80-year-old male patient, who presented in septic shock caused by necrotizing CAP. Despite inadequate empiric antimicrobial treatment, the patient survived and was able to return to his home after three weeks of hospitalization. To the best of our knowledge, this is the second case of septic shock secondary to P. aeruginosa necrotizing CAP and bacteremia, with optimal clinical outcome. We highlight the evolution of this pathology remains unpredictable, despite the factors related to the host and the bacterium.
