Molecular Respiratory Pathogen Panels in Lung Transplantation.

Area of Science:

• Clinical microbiology and infectious diseases
• Transplant medicine and surgery
• Molecular diagnostics and genomics

Background:

• Lung transplant recipients face high rates of respiratory infections, often caused by multidrug-resistant organisms.
• Rapid and accurate diagnostics are crucial for timely antimicrobial therapy in this vulnerable population.
• Molecular respiratory pathogen panels (MRPPs) represent an advancement in pathogen detection.

Purpose of the Study:

• To review the current literature on the application of molecular respiratory pathogen panels in lung transplant recipients.
• To evaluate the benefits and limitations of MRPPs in this specific clinical context.
• To discuss the potential role of MRPPs in optimizing antimicrobial stewardship and perioperative care.

Main Methods:

• Systematic review of published studies on MRPPs in lung transplant recipients.
• Analysis of data regarding diagnostic speed, accuracy, and impact on clinical decision-making.
• Evaluation of the role of MRPPs in antimicrobial prophylaxis and stewardship.

Main Results:

• MRPPs provide faster results compared to conventional microbiology, aiding in quicker diagnosis and treatment decisions.
• These panels can effectively confirm or rule out infections, supporting clinical management.
• MRPPs have limitations, including the inability to detect fungi or uncommon bacteria and the potential to misinterpret colonizing flora.

Conclusions:

• MRPPs are a valuable adjunct to traditional diagnostics in lung transplant recipients but cannot replace them.
• Integration into structured workflows and diagnostic stewardship principles is essential for optimal use.
• Further research is needed to assess cost-effectiveness and identify specific patient groups benefiting most from MRPPs.
