Title : A Rare Presentation of Acinetobacter Baumannii Hospital-Acquired Pneumonia Post- Liposuction in a Previously Healthy Patient

Abstract:

A common complication of post-surgical procedures is the development of hospital-acquired pneumonia, typically occurring 72 hours after hospital admission. Hospital-acquired pneumonia (HAP) is among the most prevalent healthcare-associated diseases. One causal organism of HAP is the gram-negative coccobacillus Acinetobacter Baumannii. This pathogen is a causal agent of bloodstream infections, urinary tract infections, and HAP, specifically in critically ill patients. The clinical presentation, treatment, and management of Acinetobacter baumannii infections are further complicated by widespread resistance to many classes of antimicrobials. Due to its ability to colonize the skin, respiratory tract, and gastrointestinal tract, distinguishing between colonization and true infection can be challenging, particularly in patients with multiple comorbidities and points of entry. However, this bacterium rarely infiltrates the immune systems of previously healthy individuals. This case report specifically highlights a previous healthy 59-year-old African American female patient who underwent liposuction of the bilateral arms, inner thighs, abdomen, and back who became critically ill following the development of complications of plastic surgery. She was then admitted to the hospital where she developed sepsis and was found to have a bowel perforation on CT scan of the abdomen and pelvis, further increasing her risk for infection. Subsequently, this patient developed respiratory failure and sputum cultures resulted in a carbapenem-resistant Acinetobacter baumannii infection. In this paper, we aim to identify a potential source of infection in a patient with Acinetobacter baumannii who was not immunocompromised. Furthermore, we highlight the management and treatment of complex Acinetobacter baumannii infections in previously healthy patients who develop HAP. This approach to treatment differs from that in patients with multidrug resistance and previous comorbidities.

Biography:

Dan Erdman and Ashley Smith are both incoming fourthyear medical students from St. George’s University who completed that Internal Medicine Core rotation this past year at Larkin Community Hospital. Eager to learn more about the complexities of the intensive care unit (ICU), they both worked with diverse patient populations with long-term complications from various surgical cases. With the help of the ICU medical team, they diligently worked to assess the development of Acinetobacter Baumannii Hospital Acquired Pneumonia and develop a case report to better understand its development, treatment options, and complex medical outcomes.
