Community-Acquired Pneumonia (CAP)

  • Study of microbial etiology and resistances of community-acquired pneumonia (CAP)
  • Study of the inflammatory response and biomarkers of CAP for diagnosis and outcome
  • Study of nonantibiotic therapy to reduce mortality of severe CAP
Projects in Progress
  • Efficacy of intravenous corticosteroids in severe CAP Microbiology of CAP according to severity scores
  • New inflammatory markers in CAP
