Case series: Fulminant community-acquired Acinetobacter pneumonia

Area of Science:

• Medicine
• Infectious Diseases
• Pulmonology

Background:

• Acinetobacter infections are typically hospital-acquired, with drug-resistant strains posing a significant threat.
• Community-acquired Acinetobacter pneumonia is an infrequent but potentially severe clinical presentation.

Observation:

• Three cases of community-acquired Acinetobacter pneumonia are presented.
• All patients had a history of regular home-brewed alcohol consumption.
• Patients presented with severe acute respiratory distress requiring mechanical ventilation and exhibited leukopenia.

Findings:

• Blood or endotracheal aspirate cultures confirmed Acinetobacter species in all cases.
• The identified Acinetobacter strains were sensitive only to high-dose sulbactam.
• The patients had a high mortality rate, succumbing within 2 to 10 days of admission.

Implications:

• This case series highlights the critical need for early recognition of community-acquired Acinetobacter pneumonia.
• Prompt and appropriate antibiotic therapy, specifically high-dose sulbactam, may improve patient outcomes.
• Further research into risk factors, such as alcohol consumption, and treatment strategies for this rare infection is warranted.
