2. 22 Topics  Universal Screening  Directed Screening  Clinical Donor Evaluation  Communication  Time Course  Epidemiology http://optn.transplant.hrsa.gov

3. 3 Required Screening for Deceased Donors  Hepatitis B core antibody  Hepatitis C serology, including  Hepatitis C nucleic acid amplification testing (NAT) (all donors)  HIV antibody  HIV NAT or 4th generation EIA (PHS increased risk)  Syphilis  Cytomegalovirus serology (CMV)  Epstein-Barr virus serology (EBV)  Blood culture  Urine culture

4. 44 NAT testing shortens the window period

7. 77  Site specific protocols are used  West Nile virus nucleic acid amplification testing  During periods of increased mosquito activity or known outbreaks  Trypansoma cruzi (serology)  At-risk donors  Coccidiomycosis (serology)  Southwestern states  Strongyloides (serology)  Human T-cell lymphotropic virus (HTLV-1) (serology)  At-risk donors Donor Screening Tests for Selected Situations

8. 8 Considerations when Evaluating Organs from Donors with Possible Infection  Has the infection been identified, and is effective treatment available?  Pneumococcal meningitis  Is the cause of presumed infection unknown?  Encephalitis of unknown cause  Is it a multidrug resistant organism?  Toxicity and poor efficacy of available treatment options  What is the extent of the infection?  Septic shock with multiple organ involvement

9. 99 Case  Potential donor: male with injection drug use  MRSA bacteremia  Septic emboli to brain  Afebrile, on antibiotics for more than 48 hours  Recipient critically ill  End stage pulmonary fibrosis  Mechanical ventilation in ICU  Should organs from this donor be transplanted? MRSA: Methicillin-resistant Staphylococcus aureus ICU: Intensive care unit. Wendt JM, et al. Am J Transplant, 2014

10. 10  Both doing well, without infection more than one year after transplant Outcome of Recipients of MRSA Endocarditis Donor  Lungs, liver, kidneys, and pancreas transplanted  Prophylaxis given to all recipients  Liver and lung recipient with recurrent MRSA MRSA: Methicillin-resistant Staphylococcus aureus

11. 11 Donors with bacteremia or endocarditis  About 5% of donors have bacteremia at procurement  Outcomes good  Recipient and donor treated  Not an MDR organism  Typically treat recipients for 7 days  Donors with endocarditis  One publication with 5 donors with good outcomes  4/5 with coagulase negative staph, one with enterococcus  MRSA and other more virulent organisms; exercise caution American Journal of Transplantation 2005; 5: 781–787

12. 12 Case  Healthy man with nausea/paresthesia/emesis after fishing trip  ED febrile/seizures/dysphagia  LP with 9 wbc, HIV/CMV/VZV/HSV/Crypto all negative  MRI no abnormalities  Deteriorated brain dead 17 days later  Presumed diagnosis was ciguatera toxin poisoning  Should this donor be used?

22. 22 Summary  Unexpected donor derived disease remains uncommon  NAT + serological testing will prevent transmission of most hepatitis B, C and HIV  Selected testing based on seasonal and other geographic exposures  Donor evaluation caution  Meningoencephalitis of unknown cuse  MDR organisms  Robust communication
