Guidance for Recognizing Central
Nervous System Infections in Potential
Deceased Organ Donors:
What to Consider During Donor
Evaluation and Organ Offers
Ad Hoc Disease Transmission
Advisory Committee
Dr. Emily Blumberg, Chair
June 25, 2012
Background

CNS infection/Meningoencephalitis (ME) is not always
recognized in donors

associated with high rates of transmission to organ recipients with
subsequent morbidity and mortality

transmission can occur in the absence of clearly recognizable donor
disease

some proven transmissions have involved donors with CNS
syndromes that were not initially attributed to infection

of great concern due to the absence of effective treatments for most
of these pathogens
DTAC Findings

Reviewed aggregate data on potential donor-derived
disease transmission reports for potential flags
regarding meningoencephalitis (ME):







Donor age and cause of brain death?
Co-morbidities that may support stroke/CVA diagnosis ?
Fever at presentation of illness/admission?
Altered mental status and/or seizures part of the presentation?
CT /MRI of head or lumbar puncture consistent with infectious process?
Was the donor an immunosuppressed host?
Any potential environmental exposures associated with organisms causing
ME?
Document Development

2011 ATC abstract for oral presentation

Encephalitis Subcommittee discussed the data and
developed a draft guidance document

Draft guidance document sent to organ specific and
OPO committee leadership for feedback/discussion


Considerable feedback received from both OPO and Thoracic Organ
Transplantation Committees
Modifications made as a result of this feedback to soften the language to be
less prescriptive
Summary of Guidance

All donors with fever (without another obvious cause) at or soon
after presentation of illness and/or otherwise unexplained
altered mental status should be considered for further
evaluation to rule out ME.

The potential donor should be discussed with the OPO’s Medical
Director and, if possible, with Infectious Diseases and Neurology
consultants.

Consideration should be given to performing a LP to look for
evidence of ME, including non-bacterial pathogens.

Additional testing based on geographic and/or demographic
factors may be considered as these results may guide posttransplant recipient management if the organs are utilized.
Summary of Guidance

If evidence suggests unsuspected or untreated CNS
infection, caution should be considered in proceeding
with allocation and acceptance of the organs for
transplantation.



If ME is suspected and the suspected pathogen is one for which there are no
treatment options (viral pathogens), extreme caution is urged before using
any organs for transplant.
The risk must be balanced with risk of poor recipient outcome if this donor
is not used.
Appropriate information should accompany the informed consent process.
Where relevant, issues relating to these concerns should be discussed with
the potential recipients.
If approved…

Guidance document will be posted on the OPTN
website as a professional resource

Will be highlighted in UNOS Update and DTAC News enewsletter
Unanimous DTAC Support for BOD
Consideration
***RESOLVED, that the guidance document “Guidance
for Recognizing Central Nervous System Infections in
Potential Deceased Organ Donors: What to Consider
During Donor Evaluation and Organ Offers”
developed by the Ad Hoc Disease Transmission
Advisory Committee is hereby approved, effective
