Plasmapheresis collections provide source plasma, including plasma
with specific antibodies, for fractionation into medicinal products.
In some Countries plasma for transfusion referred to as Fresh Frozen
Plasma (FFP) is also collected by apheresis donation.
The volume of plasma collection by apheresis per 1,000 inhabitants
reflects the volume of the national plasmapheresis programs.
In 30 reporting Countries on average 2.5 litres (range 0-14) of plasma
per 1,000 inhabitants is collected by plasmapheresis.
Apparently Austria, Bulgaria, Germany and The Netherlands stand out
as Countries with a considerbly more extensive plasmapheresis
programmes, with about 10 L or more of plasmapheresis plasma per
1,000 inhabitants/year.

Fresh Frozen Plasma (FFP) has been available
since 1941 and at first was used as volume
replacement.
After the introduction of plasmaderivatives
and hydroxyethyl starch the use of FFP has
been reconsidered and its use was indicated in
case of bleeding, or to prevent bleeding, in
patients with altered coagulation tests.

IL PLASMA FRESCO CONGELATO E’ INDICATO
– Nella fase acuta della coagulazione intravascolare disseminata
(DIC), in presenza di diatesi emorragica. In assenza di emorragia
l’impiego del plasma non è indicato. Non esiste evidenza che l’uso
profilattico possa prevenire la DIC o ridurre il fabbisogno trasfusionale.
– Nel trattamento della porpora trombotica trombocitopenica (P.T.T.) come liquido
sostitutivo nelle procedure di plasma-exchange e/o per infusione endovenosa.
– Nei deficit congeniti o acquisiti di singoli fattori della coagulazione, in presenza di
emorragia, quando non siano disponibili i concentrati dei singoli fattori.
– Come antagonista degli anticoagulanti orali, in presenza di manifestazioni
emorragiche o in previsione di un intervento chirurgico urgente o manovre invasive ad
alto rischio emorragico, una volta espletati gli altri provvedimenti terapeutici necessari
(ad esempio, la somministrazione di vitamina K)

Plasma for fractionation
• In 31 reporting Countries, an average yield of 7.2 L (range
0-26 L) per 1,000 inhabitants is found of plasma for
fractionation into medicinal products.
• However, 6 of 31 (19%) reporting Countries deliver 15 L or
more plasma per 1,000 inhabitants.
• In Europe, the main supply of plasma for fractionation is
recovered plasma: in 18 reporting MS, on average 70% of
the plasma for fractionation is from recovered plasma
(range 0-100%).

• The needs in the future
• Some ethical aspects
24
Future demand for plasmaderivatives will
be influenced by:
• Demographics and health services improvements
in emerging countries, growing acceptance,
awareness and funding
• New therapeutic indications
• Pricing pressure
• Increased competition from new manufacturers,
promotional and educational activities
• Plasma procurement and processing capacity

The EBA-IPFA position
Section 2.11 must continue to make explicit reference to agreed international
definitions for VNRBD (eg CoE, WHO, FDA, ISBT). i.e.CoE
• ‘Voluntary unpaid donation shall mean the donation of blood or blood
components by a person of his/her free will and without receiving payment in
cash or in kind in return which could be considered a substitute for money.
This also includes time off work other than that reasonably required for
donation and travel. Small tokens, gratuities, refreshments and the
reimbursement of direct costs and direct travel expenses are compatible with
the voluntary and unpaid donation of blood.’
• FDA Status of monetary incentives’
• ‘Cash or cash equivalent Tickets or events where markets for resale exists;
• transferable discounts-coupons convertible to cash; music media where
market for resale exists; vouchers for free medical tests; Scholarships paid
directly to students.’

Final considerations (1)
Homogeneous assessment of clinical needs is not yet reached: is patient
under-transfused in Spain or over-transfused in Germany, Greece
and Poland?
EU has not yet achieved self-sufficiency in plasma and plasma
derivatives.
About plasmaderivatives, demand, use and needs for patients should be
distinguished (WHO 2010)
Wide variations in per capita use of PDMP in developed countries eg
IVIg use are observed: former EU excluding UK 2007: 55 g/1000,
North America: 120 g/1000.
No evidence that clinical needs are not fulfilled in countries which have
developed robust therapeutic evidence based systems to optimal use
(eg Germany: 36 g per 1000).
32
Final considerations (2)
Europe is close to self reliance with VNRBD plasma:
IVIg use 2007 for 13 countries of the former EU with a total of 3.6
million L of plasma collected from European VNRBD, the level of
sufficiency achieved is in the range of 80 to 86%. Getting closer to 100%
sufficiency from VNRBD plasma should be further developed.
Potential negative impact of paid donations are to be considered:
On the donor health: plasma pools from paid US high-frequency, highvolume plasmapheresis donors showed significantly lower protein
content (eg total IgG: - 24%), than pools from unpaid EU or US WB or
plasmapheresis donors (R Laub et al Vox Sang 2010).
On the blood system: paying donors has been shown as a potential threat
to the wider supply of blood products, as many patients need both labile
blood products and PDMPs.
33
Final considerations (3)
EBA and IPFA continue their advocacy for developing VNRBD
with coordinated blood and plasma programmes which would
better meet all patients’ needs and comply with the donor health
requirements and the European commitment on ethical issues
and unpaid donations.
Some ethical issues have to be clarified: the anti-D paradox.
The USA – EU challenge is open!
