Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pharmacology

Background:

  • Antimicrobial agents are essential for managing acute, severe, persistent, or progressive infectious diseases.
  • Treatment efficacy hinges on accurate infection diagnosis and selecting appropriate antimicrobial agents for the causative microorganism.
  • Many disease manifestations, like fever and organ dysfunction, are nonspecific and may not stem from infections.

Purpose of the Study:

  • To review antimicrobial agents for treating human diseases caused by bacterial, fungal, viral, mycobacterial, parasitic, and chlamydial microorganisms.
  • To discuss diagnostic approaches for limiting etiologic possibilities in infectious diseases.
  • To highlight the role of empiric broad-spectrum antimicrobial treatment in serious, undiagnosed infections.

Main Methods:

  • Review of antimicrobial agents targeting a spectrum of human pathogens.
  • Clinical assessment including history, physical examination, and laboratory tests for diagnosis.
  • Evaluation of treatment trial results to guide antimicrobial selection.

Main Results:

  • Etiologic possibilities in infectious diseases can often be narrowed through clinical and laboratory assessments.
  • Noninfectious, inflammatory, or unknown mechanisms can mimic infectious disease presentations.
  • Empiric broad-spectrum antimicrobial therapy is often appropriate for serious, clinically apparent infections where the causative agent is not yet identified.

Conclusions:

  • The appropriate use of antimicrobial agents is vital for combating infectious diseases.
  • Accurate diagnosis and pathogen identification are critical for optimizing antimicrobial therapy.
  • Empiric treatment strategies are necessary and effective in managing severe infectious conditions, especially when definitive diagnosis is pending.
