Approach to suspected donor-derived infections

Area of Science:

• Transplantation immunology
• Infectious disease transmission
• Pediatric critical care

Background:

• Donor-derived infections pose a significant risk to pediatric solid organ transplant (SOT) recipients.
• Existing guidelines address anticipated transmissions (HIV, HBV, HCV) but unanticipated infections remain a challenge.
• Judicious risk-benefit assessment is essential for preventing donor-derived diseases.

Purpose of the Study:

• To define and differentiate anticipated versus unanticipated disease transmission risks in pediatric SOT.
• To identify donor characteristics associated with a higher risk of transmitting unexpected infections.
• To propose a decision-making matrix for donor acceptance and discuss future directions in donor screening.

Main Methods:

• Review of existing literature on donor-derived infections in pediatric SOT.
• Analysis of donor risk factors and clinical presentations associated with unanticipated disease transmission.
• Development of a conceptual matrix for evaluating donor acceptance based on risk stratification.

Main Results:

• Distinguishes between predictable (e.g., HIV, HBV, HCV) and unpredictable infection transmission risks.
• Highlights specific donor presentations that increase the likelihood of unanticipated disease transmission.
• Emphasizes the need for a comprehensive approach beyond standard screening protocols.

Conclusions:

• While SOT inherently carries infection transmission risks, a multifaceted strategy can mitigate significant disease transmission events.
• Comprehensive donor assessment, recipient need consideration, vigilant post-transplant monitoring, and prompt intervention are key.
• Improved donor screening and risk assessment are vital for enhancing safety in pediatric SOT.
