4. Case 1: Something Rare?
• 54 yo WM with HBV/HCV/HCC
• Day 5: Fever to 102.4, mild frontal HA since Tx
• IS: ATG, Tacrolimus, Azathioprine
• Abx: Pip-Tazo, HBIg, 3TC, Famciclovir, TMP-SMX
• SH: Suburbs, Iron worker
• PE: Non-focal except for a tender RUE
peripheral IV catheter
5. Case 1: Something Rare?
• Continued with fever, LFTs increased
• Seizure (? Hypoxemic)
• Progressive “sepsis” with elevated
LFTs and renal dysfunction
• Call from another Transplant ID
doctor: “how is your recipient doing?”
7. Case 2: Something Common?
• Patient is a 56 yo WM
• Underwent OHT November 2005
Toxo D+/R–, CMV D+/R–
Pyramethamine-Sulfadiazine
Valganciclovir
• 9 Days Post-Transplant
Donor has + blood cultures drawn the day prior to donation
Positive for Pseudomonas aeruginosa
• What Went Right? What Went Wrong?
Took several days to convey results to recipient centers
Patient was receiving ciprofloxacin for a probable UTI, which
covered the bacteria with no serious sequellae
8. Case 3: Refocusing on Risk
• One recipient was identified with post-transplant
HCV & HIV infection with no obvious risk factors
and negative pre-transplant testing
• Reported to OPO, UNOS, and CDC
• Donor – Lookback Assessment
Negative serology for HIV & HCV
Appropriately labeled as “high risk” by PHS
Guidelines
Subsequent testing of post-transfusion serum was +
for HIV and HCV by PCR
• All other recipients tested + for HIV & HCV
Ison et al. Am J Transplant. 2011; 11: 1218–1225
9. Case 4: Living Donors Are Not Immune
MMWR. 2011; 60: 297-301.
10. Unique Features of Organ Procurement
• Restricted timeline (typically 24 hours)
• Different Screening Paradigm - Not “Zero Risk”
• Donor History
Second Hand Story
Lack of Standardization
Incomplete Data Collection
• Serology-based Screening
• Variable NAT capacity and practice

11. A Significant Organ Shortage Exists
2009 DATA
Organ Transplants 28,465
Waitlist Candidates 105,567
Deaths on Waitlist 9,848
*Waiting list deaths includes removals for death, too sick to transplant, and those non-transplanted removals identified to have died within
seven days of removal from linkage to SSDMF data. Based on OPTN data as of April 16, 2010.
13. Current US Donor-Derived Disease Policy
• Policy 2: Focused on Donor Screening
Review of donor medical/social history
Defines donors at increased risk of transmitting infections
Defines required donor screening (serologic)
• Policy 4: Focused on recognizing and reporting
disease transmission
Requirement to inform recipients of new data relative to risk
„When a transplant program is informed that an organ recipient at that
program is confirmed positive for or has died from a transmissible
disease or medical condition for which there is substantial concern that
it could be from donor origin, the transplant program must notify by
phone and provide available documentation, as soon as possible and
not to exceed one complete working day, to the procuring OPO‟
Patient Safety Contact (required for each OPO and TC)

14. Disease Transmission Advisory Committee
• Workflow
Report made to Patient Safety Staff
o Prepare summary of event
o Redact identifiers
o Upload key materials to SharePoint Server
E-mail based discussion
o Initial e-mail sent to all members
o Ongoing electronic discussion
Day 45 Follow-up Reports submitted
Special Cases
o Reportable Diseases: Inform CDC
o Event-Specific Conference Calls
Monthly Conference Calls & Bi-Annual Meetings

22. Lessons Learned: DTAC Data
• Bacterial Transmissions
Likely under-recognized & under-reported
Often involves resistant bacteria
Follow-up of outstanding culture data
• Fungi
Endemic mycoses & Cryptococcus increasing
High morbidity and mortality
• Mycobacteria
• Parasites
Increase in Strongyloides, Chagas, & Amoeba
• Viral Transmissions
Increased recognition of PB19, LCMV
Need to use NAT to diagnose transmission, esp for HCV

23. Lessons Learned: DTAC Data
• Communications
Inefficient systems in place
Delays are common
• Poor systems for recognizing DDD
No cluster analysis
Severe outcomes not recognized by all recipient teams
Variable recognition and report
Management of positive cultures/result information locally
• Increased risk donors
Variable definitions used
Variable understanding of risk
Variable follow-up of recipients
• Living donors
