Summary
Severe community-acquired pneumonia etiology was identified in over half of patients, with Streptococcus pneumoniae being the primary pathogen. Most isolates were susceptible to benzylpenicillin, indicating its utility in empirical therapy.
Area of Science:
- Microbiology
- Immunology
- Pulmonology
Context:
- Severe community-acquired pneumonia (CAP) poses a significant public health challenge.
- Accurate etiological diagnosis is crucial for effective treatment strategies.
- This study focused on male patients with high-risk CAP (classes III-V).
Purpose:
- To determine the etiological agents of severe CAP in male patients.
- To assess the antimicrobial susceptibility of isolated pathogens, particularly Streptococcus pneumoniae.
- To inform the development of regional empirical antibacterial therapy guidelines.
Summary:
- Microbiological and immunological analyses were performed on 40 male patients with severe CAP.
- The etiology was identified in 52.5% of cases, with Streptococcus pneumoniae being the predominant pathogen (61.6%).
- Staphylococcus aureus and Klebsiella pneumoniae were also identified. Legionnaires' disease was not detected.
- Most Streptococcus pneumoniae isolates were susceptible to benzylpenicillin, with one case of moderate resistance noted, but susceptibility to ceftriaxone was maintained.
Impact:
- Provides crucial etiological data for severe CAP in the studied population.
- Highlights the continued effectiveness of benzylpenicillin against most Streptococcus pneumoniae isolates.
- Informs the development of evidence-based national or regional empirical antibacterial therapy programs for severe CAP.
