Update on Donor Screening
for TSEs
Melissa A. Greenwald, MD
Division of Human Tissues
Office of Cellular, Tissue and Gene Therapies
AATB 29th Annual Meeting
Hollywood, Florida
Council of Accredited Tissue Banks
Tuesday 20 September 2005
Today’s talk will focus on:
• What are Transmissible Spongiform
Encephalopathies (TSEs)?
• Background on CJD/vCJD Draft
Guidance
• Specific recommended deferral criteria
• Allow time for discussion and
questions
What are TSEs?
• Human Transmissible Spongiform
Encephalopathies (TSEs) include
Creutzfeldt Jakob Disease (CJD) and
variant Creutzfeldt Jakob Disease
(vCJD)
• CJD has been a known agent, but
vCJD has only been identified in the
recent past—is a human form of
Bovine Spongiform Encephalopathy
(BSE), known as “mad cow disease”
What are TSEs? (cont.)
• The TSE agent is a prion–a poorly
understood agent; is an abnormal
protein that causes a degenerative
disease of the central nervous
system (CNS) that is not curable and
invariably leads to the death of the
person with the disease
• The agent is very difficult to destroy
and would not be inactivated by
current tissue processing technology
What are TSEs? (cont.)
• Blood from some animals
experimentally infected with TSE
agents, including the BSE agent,
contains low levels of infectivity
• Several TSE agents, including BSE,
have been experimentally
transmitted by transfusion
• Agent for vCJD is ingested, so it is
likely that the agent has a bloodborne
phase in humans (the
specifics of the pathology in humans
is poorly understood)
What are TSEs? (cont.)
• There are no published studies
showing transmission of the BSE
agent via HCT/Ps; however
• vCJD agent is present in lymph
nodes and tonsils of infected
patients
• vCJD has been transmitted via blood
transfusion in the UK
• Transmission of CJD via cornea and
dura mater has already been
demonstrated in humans
What are TSEs? (cont.)
• Because of studies showing blood
infectivity of TSE agents, it is a
theoretical risk that HCT/Ps have the
potential to transmit TSEs
• Because of this theoretical risk, FDA
is concerned about the potential for
transmission of TSEs via HCT/Ps
and therefore considers TSEs a
RCDAD and requires donor
screening for these agents
CJD/vCJD draft guidance
• Deferral of tissue donors for risk
factors for “classic” (sporadic)
CJD—already recommended in the
1997 guidance for industry
• The draft guidance for CJD/vCJD
incorporated those deferrals, and in
addition recommends deferrals for
risk factors for variant CJD—travel or
residence in BSE-affected countries
• The draft guidance published June
2002
• There was a 6 month comment
CJD/vCJD draft guidance
• Draft guidance was modeled after the
guidance for industry for blood
donors, issued August 2001
• Recommends the same countries,
dates, and lengths of
travel/residence as does the
guidance for blood donors
• Permits an exception for the
collection and storage of
hematopoietic stem cells from
donors who live in or travel to a BSEaffected
country (for urgent medical
CJD/vCJD draft guidance
• Comments reviewed at CBER
• Final recommendations for
CJD/vCJD screening will be
incorporated into the final Donor
Eligibility guidance when published
• As of May 25, 2005 Transmissible
Spongiform Encephalopathy (CJD
and vCJD) is a relevant
communicable disease agent or
disease (RCDAD) and establishments
must screen for CJD/vCJD
CJD/vCJD draft guidance
• Specific deferral criteria in the draft
guidance are an indication of FDA’s
current thinking about how to
adequately and appropriately reduce
the risk of infectious disease
transmission by this agent
• Until a final guidance is issued,
establishments would not
necessarily have to “adopt” the
recommended deferral criteria but
the regulations do require some
screening for TSEs (including CJD
and vCJD)
CJD/vCJD draft guidance
• May use alternate screening criteria as long
as the screening criteria are at least as strict
as those recommended by FDA (i.e., are as
effective to adequately and appropriately
reduce the risk of infectious disease
transmission)
• No testing recommendations made—there
are no FDA approved tests for humans
CJD/vCJD Risks for Donor
Screening
• Persons who have been diagnosed
with vCJD or any other form of CJD
• Persons who have been diagnosed
with dementia or any degenerative or
demyelinating disease of the CNS or
other neurological disease of
unknown etiology [Possible that
FDA may make a distinction between
dementia and acute delirium (e.g.,
delirium caused by toxic/metabolic
disease or recent head trauma)]
Donor Screening (cont.)
• Persons who are at increased risk for CJD
– Receipt of human dura mater transplant
– Receipt of human pituitary-derived growth
hormone
– One or more blood relatives diagnosed with
CJD
• Persons who spent three months or more
cumulatively in the U.K. from the
beginning of 1980 through the end of 1996
Donor Screening (cont.)
• Persons who are current or former
U.S. military members, civilian
military employees, or dependents of
a military member or civilian
employee who resided at U.S.
military bases in Northern Europe for
6 months or more from 1980 through
1990, or elsewhere in Europe for 6
months or more from 1980 through
1996
Donor Screening (cont.)
• Persons who lived cumulatively for 5
years or more in Europe between
1980 and the present
• Persons who received any
transfusion of blood or blood
components in the U.K. between
1980 and the present
• NOTE—If the person being
interviewed is not familiar with the
term CJD, you may take that as a
negative response
The UK
• For the guidance, the UK includes
– England
– Northern Ireland
– Scotland
– Wales
– Isle of Man
– Channel Islands
– Gibraltar
– the Falkland Islands.
Military Bases
• In Northern Europe includes
– Germany, UK, Belgium, Netherlands
– Deferral from 1980-1990
• In Southern Europe includes
– Greece, Turkey, Spain, Portugal, Italy
– Deferral from 1980-1996
Family History of CJD
• Would be ineligible UNLESS:
– the diagnosis of CJD was subsequently found
to be an incorrect diagnosis;
– the CJD was iatrogenic; or
– laboratory testing (gene sequencing) shows
that the donor does not have a mutation
associated with familial CJD
