DONORMO
Advances and
achievements of DONORMO
ACHIEVEMENTS
Until 2005, 40 unrelated
transplants have been practiced on Mexican patients using
unrelated donors or umbilical chord cells units, most of
them provided by the NY Blood Center and others by BACECU
and 7 with unrelated donors from DONORMO. On November 2005,
one of our couriers carried an unrelated stem cell unit for
a patient in Europe. The patient received the transplant 48
hours after the extraction of the blood stem cells from the
donor in Mexico.
We have participated since
1989 in over 400 of the 1500 bone marrow transplants
performed in Mexico. The first bone marrow transplant with
an unrelated donor from DONORMO performed in Mexico,
occurred in May 2001 at the Ángeles de Las Lomas Hospital.
Four more have been done and 6 with partially
compatible parents used as donors. Every time DONORMO and the
Dept. of Inmunogenetics, InDRE, have handled all technical
issues related with the
selection, molecular typing, cryopreservation, delivery of
the unit to the transplant center and
molecular follow up of the graft.
2,066 searches have been
performed for Mexican, Hispanic and other patients
worldwide, with ethnically distinct composition .
We enforce technical and
scientific growth trough international meetings supported by
the National Academy of Medicine, The National
University in Mexico, UNAM and the Secretary of Health.
International didiactic and practical courses in Histocompatibility
and Molecular Genetics are yearly academically sposnsored by the American Board of Histocompatibility and Inmunogenetics,
The Graduate Division of the Faculty of Medicine, UNAM, the American Society for Histocompatibility and Immunogenetics
(ASHI) and the Secretary of Health.
We have the only Mexican
Laboratory internationally certified by ASHI for
clinical work, one out of the only two in
Latin America.
CURRENT SITUATION
Day after day, in the
whole world the number of people who are affected with
hematological diseases increases and so the tragedy for
thousands of families. Each year more than 30,000
people are diagnosed with life threatening diseases like
leukemia, severe aplastic anemia and other blood related
diseases of genetic origin for which bone marrow
transplantation can be its only life alternative.
In Mexico there are
almost 6000
patients/year who awaits for a bone marrow transplant.
One of the most important
limitations to receive a transplant is compatibility
of the HLA complex; therefore, the
first option is to find a donor within the family of the
patient. Only 35% of patients will
find an identical donor within the family; for the others,
their only hope of survival will be to find an unrelated
compatible donor. Therefore, bone marrow unrelated
registries were created.
The International Bone
Marrow Transplant Register (IBMTR) collects information from
492 sites and indicates that up to 2004 115,000 allogeneic
BMT ( related and unrelated donor -
recipient ) have been performed; of these, 15,000 where
performed in 2000 alone.
75 unrelated bone marrow
donor registries exist in 41 countries around the world and
33 Umbilical cord stem cell registers in 21 countries. The
official numbers were 9,580,536 unrelated donors and 198,000
Umbilical cord units up to September, 2005.
In Mexico our DONORMO has
only 5,100 (Dec. 2005) registered donors and theres 6000
cases/year awaiting for a bone marrow transplant. The closer the ethnical
background between donor and recipient is, the greater the
probability of finding an HLA match.
The NMDP (National Marrow Donor Program)
in USA, has over 5 million registered donors, 73% Caucasian, 9%
African-American, 8% Hispanic, 7% Oriental and 2%
Native-American.
This calls our attention
since it is relevant to increase the efforts in Mexico
and other countries that represent ethnical groups
other than Caucasians all over the world, so a
compatible donor can be found to help survive patients
of different ethnical composition. Another source for stem cells
is as already mentioned, the UC which is
disposed after delivery.
There's more than 150,000
Umbilical Cord Units in several Altruistic Banks all over
the world. In Mexico, The recently
created umbilical cord blood
bank (BACECU) has only 75 available units (Feb 2006) to offer to
patients. Cost will be reduced by 40% with the
presence of Public Umbilical Cord Cells
Banks, since units are also available for the international
transplant centers at the
international cost. This will make BACECU financially
self suffcient at mid term, creating an important
social benefit for low income patients. BACECU will be able
to donate units for low resources children. Only with
great team effort, education, financial support of the
society and an intense dedication, a bigger number
of patients will be cured with this procedures.
