Opportunities over 40 yrs In TRANSFUSION MEDICINE (1978- 2017) Pearl Toy M.D. Professor Emeritus
I have no relevant financial relationships to disclose.
LEARNING OBJECTIVES • State one problem that led to advancement in these Transfusion Medicine related issues since 1978: • Human Immunodeficiency Virus • Hepatitis B Virus • Transfusion Related Acute Lung Injury
Bilateral infiltrates on CXR? Yes/No Ruled out TACO? Yes/N0 Ruled out septic transfusion reaction? Yes/No Alternate ARDS risk factor present? Yes/no a. If Yes, name the ARDS risk factor______ b. What was the lung status before or during the transfusion? ____ Stable or improving (as in TRALI) ____ Worsening (as in Transfused ARDS) Evaluation of hypoxia (P/F<300) during or <6 hrs after transfusion

No test for HIV in the blood supply: 1981-1985 HOSPITAL (ACADEMIC) Assistant Professor, UCSF SF General Hospital Increasing numbers of AIDS patients DONOR CENTER (COMMUNITY) Director, ARC, San Jose Increasing numbers of reports of AIDS, associated with transfusion
Before HIV testing was available in 1985: 12,000 – 25,000 cases of Transfusion-Associated HIV ( CDC)
San Jose ARC Director Hat (1983 – 1984) DONOR QUESTIONING DONOR TESTING What? How? Where? Did the donor understand the information? 1984: Surrogate test 1985: HIV test
Positive Effect: Birth of “Transfusion Medicine” NIH Coined the NEW term “TRANSFUSION MEDICINE” NIH Started the TRANSFUSION MEDICINE ACADEMIC AWARDS in 1983, and funding FOR Transfusion medicine research Transfusion Medicine community Improved responses transfusion-associated infections

Surprise in 2002:TRALI patient……dies Received cognate anti-HLA in a plateletpheresis unit BUT: Other recipients of cognate anti-HLA from the same donor did not get TRALI NEED for MORE RESEARCH: NIH WORKING GROUP, CHAIR Definition presented at Canadian Consensus Conference
TRALI Definition Toy P et al (Crit Care Med 2005;33:721-6) Kleinman SH et al (Transfusion 2004; 44;1774-89) TRALI is new ARDS during or <6 hr after transfusion TRALI is new ARDS during or <6 hr after transfusion Possible TRALI: temporally related to another ARDS risk factor present
ARDS: Plasma leaks into air spaces Platelet-neutrophil aggregates in blood Megakaryoctes in lungs make platelets.
Most common conditions that can cause ARDS, without transfusion • Pneumonia • Aspiration • Sepsis • Shock • Trauma • - both lungs • - multiple fractures
>60 Conditions can cause ARDS, without transfusion • Examples: • Lung transplant, graft failure • Hematopoietic stem cell transplant, chemoradiation • Cardiopulmonary bypass • Many drugs • Genetic mutation of surfactant protein-B
Cause of ARDS, no Tx: Sepsis Toxic granulations Plasma leaks out of blood
Cause of ARDS: TRALI or known ARDS risk factor? • PROBLEM: ARDS transfusion in a patient who already has one of >60 ARDS risk factors: • Pneumonia • Aspiration • Sepsis • Severe Trauma • Lung transplant, graft failure • Hematopoietic stem cell transplant, chemoradiation • Cardiopulmonary bypass, lung surgery • Many drugs • Genetic mutation of surfactant protein-B • Other
Possible TRALI • Definition in our study: • ARDS in a patient with a • ARDS risk factor and related • Worseninglung function • <12 hrsBEFORE transfusion
