Study Notes
Ventilator-Associated Pneumonia (VAP)
- VAP is the most prevalent hospital-acquired infection in the ICU, resulting in significant morbidity and mortality.
- 9-27% of all VAP etiology involves S.maltophilia, particularly in patients with severe diseases.
Stenotrophomonas maltophilia (S.maltophilia)
- S.maltophilia is a virulent opportunistic pathogen that leads to pneumonia in populations with depleted immunity or serious chronic diseases.
- The use of mechanical ventilation is an important risk factor for colonization, which exacerbates pneumonia.
Treatment and Mortality Rate
- The serious broad-spectrum resistance of S.maltophilia to antibiotics has led to a difficult treatment of VAP due to S.maltophilia.
- Mortality rate of patients infected with multidrug-resistant isolates was 60-71.4%, much higher than the 37-50% mortality rate found in the antibiotic-sensitive group.
Clinical Management of VAP due to S.maltophilia
- There is a need for better management recommendations for VAP due to S.maltophilia, a fatal pathogen.
- There is a lack of new antimicrobial resistance management studies on VAP with multiple drug-resistant S.maltophilia.
