Rapid molecular testing for antimicrobial stewardship and solid organ transplantation

Area of Science:

• Infectious Diseases
• Transplant Medicine
• Clinical Microbiology

Background:

• Molecular platforms enable early detection of infectious pathogens.
• Solid organ transplant (SOT) recipients are a vulnerable population requiring timely diagnostics.
• Rapid diagnostic tests (RDTs) offer potential advantages for managing infections in SOT patients.

Purpose of the Study:

• To review clinical outcomes associated with RDT use in SOT patients.
• To identify benefits and drawbacks of RDTs in the SOT population.
• To summarize current literature on RDT efficacy in SOT recipients.

Main Methods:

• Conducted a PubMed search for RDTs and SOT studies.
• Included studies with at least one SOT patient.
• Reviewed full-text, English-language, peer-reviewed publications.

Main Results:

• RDTs integrated with antimicrobial stewardship programs (ASPs) led to faster identification, optimal therapy, reduced hospital stay, and lower mortality.
• Potential drawbacks include overdiagnosis (e.g., Clostridium difficile) and reduced yield for certain pathogens (e.g., Aspergillus).
• Eleven studies were included in the review.

Conclusions:

• Current data suggests RDTs improve SOT patient outcomes and reduce antimicrobial misuse when used with ASPs.
• Further research is needed on clinical outcomes specifically in SOT patients.
• Optimizing RDT use with traditional microbiology methods is crucial for SOT care.
