Condition

Herpes virus causing glandular fever (infectious mononucleosis).

Individual at risk

Recipient (and ?donor)


Guidance at RECRUITMENT

ACCEPTABLE


Guidance at CT

ACCEPTABLE


Guidance at Work-up

The following serological tests should be obtained

• VCA-IgM

• VCA-IgG

• (EBNA-IgG)


Outcomes and recommended actions based on EBV serology and PCR:

Potential serology/PCR combinations:


1) VCA-IgM neg AND VCA-IgG pos or neg.

''Donor can be cleared - transplant centre should be informed for serological/PCR status

2) VCA-IgM-pos AND VCA-IgG and/or EBNA positive

Inform the TC and proceed donation without EBV-DNA PCR


3)VCA-IgM-pos AND VCA-IgG and/or EBNA weak or negative

Request EBV-DNA PCR

a) If EBV-DNA PCR negative--> inform the TC and proceed donation

b) If EBV-DNA PCR positive --> inform the TC, donation will have to be postponed and EBV serology repeated after 1 month.

Justification for guidance

Primary EBV infection or reactivation in a transplant recipient is associated with post-transplant lymphoproliferative disease, amongst other morbidity.
