Prevalence of ataxia in children. Kristin E. Musselman, Cristina T. Stoyanov, Rhul Marasigan, Mary E. Jenkins, Jürgen Konczak, Susanne M. Morton, and Amy J. Bastian; Neurology January 7, 2014 vol. 82 no. 1 80-89, doi: 10.1212/01.wnl.0000438224.25600.6c
The prevalence of childhood ataxias in Europe was estimated to be ∼26/100,000 children and likely reflects a minimum prevalence worldwide. The findings show that ataxia is a common childhood motor disorder with a higher prevalence than previously assumed.

If rhEpo or its analogues improve(s) the muscle and mitochondrial function it would help improve the cardiac function. However, none of these studies and clinical trials mentioned the long-term effect of rhEpo on the heart of FRDA. Thus, an effort designing a clinical trial involving treatments a long term in FRDA patients are strongly recommended.

Pacients i científics s’alien per combatre l’Atàxia de Friedreich
·
Afectats i
familiars units en una plataforma, dues associacions de pacients i dos centres
de recerca biomèdica s’uneixen en la lluita contra aquesta malaltia neurològica
hereditària que a dia d’avui no té cura.
·
Científics del
Centre de Biologia Molecular Severo Ochoa de Madrid i de l’IRB Barcelona desenvoluparan
un projecte de teràpia gènica consistent en introduir a les cèl·lules del cos una
còpia correcta del gen defectuós que causa la malaltia.
·
L’Atàxia de
Friedreich afecta a dues persones per cada 100.000 habitants de mitjana,
únicament d’origen europeu (caucasians). A Espanya la incidència és més gran: s’estima
en 4,7 casos per cada 100.000 individus.
Barcelona, dijous
14 de novembre de 2013.- La Federació
d’Atàxies d’Espanya (FEDAES) en representació de la plataforma GENEFA per a la
cura de l’Atàxia de Friedreich, l’associació Babel Family per a la investigació
biomèdica de l’Atàxia de Friedreich, el Centre de Biologia Molecular Severo
Ochoa (CMBSO) i l’Institut de Recerca Biomèdica (IRB Barcelona) han signat un conveni
a través del qual aquestes associacions de pacients i afectats finançaran amb
donacions i durant tres anys un projecte de recerca per lluitar contra l’Atàxia
de Friedreich.
L’Ataxia de Friedreich és una malaltia degenerativa rara del
sistema nerviós que afecta a la coordinació, equilibri i moviment. És una malaltia
monogènica, és a dir, causada per la deficiència d’un únic gen. Els afectats han
heretat d’ambdós progenitors el gen de la frataxina alterat. L’objectiu del projecte
és obtenir eines moleculars per transportar fins les cèl·lules del cos i en especial a un tipus de neurones que
pateixen degeneració i causen la malaltia, una còpia correcta del gen defectuós
per restaurar els nivells normals de frataxina i detenir els símptomes
degeneratius de la malaltia.
La Plataforma GENEFA lidera la recaptació dels 300.000
euros necessaris per desenvolupar aquest projecte basat en la teràpia gènica.
Juan Carlos Baiges, en representació de FEDAES/GENEFA i Babel Family per a aquest
projecte, expressa la seva il·lusió “perquè és el primer pas cap a l’obtenció
d’un tractament eficaç basat en coneixement científic bàsic molt sòlid”. I afegeix,
“tenim un projecte esperançador per endavant que pot apropar-nos a la promesa
d’una teràpia”.
Ernest Giralt de l’IRB i Javier Díaz-Nido del CBMSO, co-líders
científics del projecte subratllen que “és infreqüent que els investigadors
bàsics entrin en un diàleg directe amb els pacients i aquest projecte és
magnífic perquè des de l’inici ens recorda que les respostes a les malalties sorgeixen
des de la recerca bàsica, el pilar de tota aplicació futura”.
UN SOL GEN ALTERAT
El metge alemany Nicholas Friedreich la va descriure per
primera vegada cap el 1860. L’Atàxia de Friedreich és una malaltia del sistema
nerviós per a la quual no existeixen ni cura ni tractaments específics. Encara
que és el tipus d’atàxia més majoritària, és una malaltia rara. Afecta,
aproximadament, a dues de cada 100.000 persones únicament entre poblacions d’origen
europeu (caucasians). A Espanya i França els números estimatius d’incidència són
més grans, amb una prevalença de 4,7 casos per 100.000 habitants, el que suggeriria
que probablement l’afectació es va iniciar en l’àrea geogràfica de la serralada
Cantàbrica.
L’Atàxia de Friedreich se sol manifestar en una franja que va dels 5 als 25 anys, amb pèrdua progressiva d’equilibri, coordinació i moviment. Uns deu
anys després els primers símptomes, els afectats acostumen a necessitar cadira
de rodes. L’esperança de vida es veu greument afectada, sobretot
si hi ha complicacions secundàries sèries, com ara la cardiomiopatia progressiva.
RESTABLIR EL GEN DE LA FRATAXINA AMB TERÀPIA GÈNICA
EL 1996, un grup internacional de científics va
identificar la causa de l’Atàxia de Friedreich com un defecte en el gen que codifica per a la proteïna
frataxina, situat en el cromosoma 9. Una de les
vies més prometedores per corregir els baixos nivells d’aquesta proteïna en les
cèl·lules és la teràpia gènica, és a dir, introduir en el nucli de les
cèl·lules la còpia correcta del gen.
“Tenim el gen complet aïllat, empaquetat en vectors o
“vehicles” transportadors i hem testat l’eficàcia en cèl·lules in vitro de
pacients. Ara hem de millorar el transport cap a les cèl·lules del sistema
nerviós i testar l’eficiència en ratolins amb atàxia” assenyala Javier Díaz-Nido,
líder del grup “Reparació neuronal i teràpia molecular en neurodegeneració.
Atàxies espinocerebeloses”, del Centre de
Biologia Molecular Severo Ochoa, centre mixt de la Universitat Autònoma de
Madrid i del CSIC, i que també pertany al Centre de Recerca Biomèdica en Xarxa sobre Malalties Rares
(CIBERER, en castellà).
El doctor Díaz-Nido és un dels màxims experts mundials en
atàxies, fa més de deu anys que estudia en concret l’Atàxia de Friedreich a
nivell molecular i desenvolupa tècniques per convertir la teràpia gènica en una realitat
més pròxima. “En els deu darrers anys s’han fet grans avançaments en teràpia gènica
gràcies a la contribució de centenars de científics de tot el món. Falta un
últim esforç perquè sigui una realitat clínica però ja comencem a entreveure
que la teràpia gènica serà una opció per tractar aquestes malalties d’origen
genètic”, sosté Díaz-Nido.
SUPERAR LA
BARRERA DEL CERVELL
El cervell està protegit per la barrera hematoencefàlica.
Aquesta barrera dificulta l’entrada al cervell de substàncies tòxiques però
també és un mur per als fàrmacs. És en aquesta àrea de coneixement on és
crucial la col·laboració amb Ernest Giralt en el projecte. El doctor Giralt és
líder del grup “Disseny, síntesi i estructura de pèptids i proteïnes” i coordinador
del programa de Química i Farmacologia Molecular de l’IRB Barcelona, amb una llarga
experiència i reconeixement internacional sobre la química de pèptids i
sistemes d’administració de fàrmacs. En el seu laboratori han generat i provat
satisfactòriament una sèrie de pèptids “llançadora” capaços de creuar la
barrera hematoencefàlica. “La nostra principal missió és adaptar les nostres “llançadores”
als vectors carregats amb el gen de la frataxina perquè puguin franquejar primer la barrera
hematoencefàlica i introduir-se després en el nucli de les cèl·lules del
sistema nerviós”, indica Meritxell Teixidó, investigadora associada de l’IRB i
responsable d’aquesta línia de recerca.
El treball conjunt s’inicia aquest novembre de 2013 amb
un termini de tres anys. En aquest temps, l’equip de científics espera tenir enllestida
la prova de concepte que permeti saltar
de la ciència bàsica de laboratori a proves pre-clíniques amb models animals més
sofisticats i avançar cap a una teràpia gènica per a l’Atàxia de Friedreich.

La Ataxia de
Friedreich afecta a dos personas por cada 100.000 habitantes de media,
únicamente de origen europeo (caucasianos). En España la incidencia es mayor: se
estima en 4,6 casos por cada 100.000 individuos.
Barcelona,
jueves 14 de noviembre de 2013.- La
Federación de Ataxias de España (FEDAES) en representación de la plataforma
GENEFA para la cura de la Ataxia de Friedreich, la asociación Babel Family para
la investigación biomédica de la Ataxia de Friedreich, el Centro de Biología
Molecular Severo Ochoa (CMBSO) y el Instituto de Investigación Biomédica (IRB
Barcelona) han firmado un convenio a través del cual dichas asociaciones de
pacientes y afectados financiarán con donaciones y durante tres años un
proyecto de investigación para atajar la Ataxia de Friedreich.
La Ataxia de Friedreich es una enfermedad
degenerativa rara del sistema nervioso que afecta a la coordinación, equilibrio
y movimiento. Es una enfermedad monogénica, es decir, causada por la deficiencia
de un único gen. Los afectados han heredado de ambos progenitores el gen de la
frataxina alterado. El objetivo del proyecto es obtener herramientas
moleculares para transportar hasta las células del cuerpo y en especial a un
tipo de neuronas que sufren degeneración y causan la enfermedad, una copia correcta
del gen defectuoso para restaurar los niveles normales de frataxina y detener
los síntomas degenerativos de la enfermedad.
La Plataforma GENEFA lidera la recaudación de los
300.000 euros necesarios para desarrollar este proyecto basado en la terapia
génica. Juan Carlos Baiges, en representación de FEDAES/GENEFA y Babel Family
para este proyecto expresa su ilusión “porque es el primer paso hacia la
obtención de un tratamiento eficaz basado en conocimiento científico básico muy
sólido”. Y añade, “tenemos un proyecto esperanzador por delante que puede
acercarnos a la promesa de una terapia”.
Ernest Giralt del IRB y Javier Díaz-Nido del CBMSO,
colíderes científicos del proyecto subrayan que “es infrecuente que los
investigadores básicos entren en un diálogo directo con los pacientes y este
proyecto es magnífico porque desde el inicio nos recuerda que las respuestas a
las enfermedades surgen desde la investigación básica, el pilar de toda
aplicación futura”.
UN SÓLO GEN
ALTERADO
El médico alemán Nicholas Friedreich la describió
por primera vez hacia 1860. La Ataxia de Friedreich es una enfermedad del
sistema nervioso para la cual no existen ni cura ni tratamientos específicos. Aún
siendo la más común de todos los tipos de ataxia, es una enfermedad rara. Afecta,
aproximadamente, a dos de cada 100.000 personas únicamente entre poblaciones de
origen europeo (caucasianos). En España y Francia los números estimativos de
incidencia son mayores, con una prevalencia de 4,7 casos por 100.000 habitantes,
lo que sugeriría que probablemente la afectación se inició en el área
geográfica de la cordillera Cantábrica.
La Ataxia de Friedreich se manifiesta normalmente entre los 5 y los 25 años de edad, con pérdida progresiva de equilibrio, coordinación y movimiento.
Unos diez años después de los primeros síntomas, los afectados suelen precisar
silla de ruedas. La esperanza
de vida se ve gravemente afectada, sobre todo si hay complicaciones secundarias
serias, como la cardiomiopatía progresiva.
RESTABLECER EL GEN DE LA FRATAXINA CON TERAPIA
GÉNICA
En 1996, un grupo internacional de científicos
identificó la causa de la Ataxia de Friedreich como un defecto en el gen que codifica para la
proteína frataxina, situado en el cromosoma 9. Una de las vías más prometedoras para corregir los bajos niveles de
esta proteína en las células es la terapia génica, tratando de introducir en el
núcleo de las células la copia correcta del gen.
“Tenemos el gen completo aislado, empaquetado en
vectores o “vehículos” transportadores y hemos testado la eficacia en células in
vitro de pacientes. Ahora debemos mejorar el transporte hacia las células del
sistema nervioso y testar la eficiencia en ratones con ataxia” señala Javier
Díaz-Nido, líder del grupo “Reparación neuronal y terapia
molecular en neurodegeneración. Ataxias espinocerebelosas”, del Centro de Biología Molecular Severo Ochoa, centro
mixto de la Universidad Autónoma de Madrid y del CSIC, que también pertenece al
Centro de Investigación Biomédica en Red sobre Enfermedades Raras (CIBERER).
El doctor Díaz-Nido es uno de los máximos expertos
mundiales en ataxias, lleva más de diez años estudiando en concreto la Ataxia
de Friedreich a nivel molecular y desarrollando técnicas para convertir la
terapia génica en una realidad más próxima. “En los diez últimos años se han
hecho grandes avances en terapia génica gracias a la contribución a nivel
mundial de cientos de científicos. Falta un último esfuerzo para que sea una
realidad clínica pero empezamos a vislumbrar ya que la terapia génica será una
opción para el tratamiento de estas enfermedades de origen genético”, sostiene Díaz-Nido.

SUPERAR LA
BARRERA DEL CEREBRO
El cerebro está protegido por la barrera
hematoencefálica. Dicha barrera dificulta la entrada en el cerebro de
sustancias tóxicas pero también es un muro para los fármacos. Es en esta área
de conocimiento donde es crucial la colaboración con Ernest Giralt en el
proyecto. El doctor Giralt es líder del grupo “Diseño, síntesis y estructura de
péptidos y proteínas” y Coordinador del programa de Química y Farmacología
Molecular del IRB Barcelona, con una larga experiencia y reconocimiento
internacional sobre la química de péptidos y sistemas de administración de
fármacos. En su laboratorio han generado y probado satisfactoriamente una serie
de péptidos “lanzadera” capaces de cruzar la barrera hematoencefálica. “Nuestra
principal misión es adaptar nuestras “lanzaderas” a los vectores cargados con
el gen de la frataxina para que puedan franquear primero la barrera
hematoencefálica e introducirse después en el núcleo de las células del sistema
nervioso”, indica Meritxell Teixidó, investigadora asociada del IRB y
responsable de esta línea de investigación.
El trabajo conjunto se inicia este noviembre de 2013
con un plazo de tres años. En este tiempo, el equipo de científicos espera
tener lista la prueba de concepto que permita saltar de la ciencia básica de
laboratorio a pruebas pre-clínicas con modelos animales más sofisticados y
avanzar hacia una terapia génica para la Ataxia de Friedreich.

Patients and scientists join forces to tackle Friedreich’s Ataxia
Patients and scientists join forces to tackle Friedreich’s Ataxia
• Patients and their families united in a single platform, two patients’ associations, and two biomedical research centres join forces in the fight against this hereditary neurological disease for which there is still has no cure.
• Scientists at the “Centro de Biología Molecular Severo Ochoa” in Madrid and IRB Barcelona develop a gene therapy project that involves introducing into the body’s cells a correct copy of the defective gene that causes the disease.
• Friedreich’s Ataxia affects approximately 2 in every 100,000 people of European origin (Caucasians). In Spain the incidence of this disease is higher, with an estimated 4.7 cases per 100,000 population.
Barcelona, Thursday 14 November 2013.- The Spanish Federation of Ataxia (FEDAES)—in representation of the GENEFA Platform for a Friedreich's Ataxia cure—, the Babel Family association for biomedical research into Friedreich’s Ataxia, the “Centro de Biología Molecular Severo Ochoa” (CMBSO), and the Institute for Research in Biomedicine (IRB Barcelona) have signed an agreement through which these patients’ associations will fund, by means of donations, a 3-year research project addressing Friedreich’s Ataxia.
Friedreich’s Ataxia is a rare degenerative disease of the nervous system that affects coordination, balance and movement. It is a monogenic disease, that is to say, it is caused by a defect in only one gene. Those affected by this disorder have inherited an altered frataxin gene from both parents. The project aims to develop molecular tools to transport a correct copy of the defective gene to all the cells of the body and particularly to a kind of neuron that undergoes degeneration and causes the disease. This approach seeks to restore the normal levels of frataxin and to stop the manifestation of the degenerative symptoms of the disease.
The GENEFA Platform heads the money-raising campaign to collect the 300,000 euros required to develop this gene therapy project. Juan Carlos Baiges, in representation of FEDAES/GENEFA and the Babel Family for this project, expresses his enthusiasm, “it is the first step towards achieving an effective treatment based on solid basic research knowledge”, and adds, “we have a motivating project ahead that may lead us closer to a treatment.”
Ernest Giralt, at IRB Barcelona, and Javier Díaz-Nido, at CBMSO, scientific co-leaders of the project, stress that, “it is uncommon for basic researchers to have direct contact with patients and this project is fantastic because it reminds us that the solutions to diseases derive from basic research, the cornerstone of future applications.”
A SINGLE ALTERED GENE
The German physician Nicholas Friedreich described the disease for the first time around 1860. Friedreich’s Ataxia is a disease that affects the nervous system and for which there is no cure or specific treatments. Although Friedreich’s Ataxia is the most common kind of ataxia, it is a rare condition. It affects approximately 2 in every 100,000 people of European origin (Caucasians). In Spain and France the incidence of this disease is higher, with a prevalence of 4.7 cases per 100,000 population, suggesting that this disease probably originated in the geographic area of the Cantabrian mountain range.
Friedreich’s Ataxia normally appears before the ages of 5 and 25, causing progressive loss of balance, coordination and movement. About ten years after the onset of the first symptoms, those affected usually become wheelchair-bound. Life expectancy is severely reduced, above all when there are serious secondary complications, such as progressive cardiomyopathy.
RESTORING THE FRATAXIN GENE THROUGH GENE THERAPY
In 1996, an international group of scientists identified the cause of Friedreich’s Ataxia as a defect in a gene that codes for the protein frataxin, located in chromosome 9. One of the most promising strategies to correct the low cellular levels of this protein is through gene therapy, by attempting to introduce a correct copy of the gene into cell nuclei.
“We have fully isolated the gene and packaged it in transport vectors or “vehicles” and we have tested its efficiency in patient cells in vitro. Now we have to improve transport to the cells of the nervous system and test the efficiency in mice with ataxia,” explains Javier Díaz-Nido, head of the group “Neuronal repair and molecular therapy in neurodegeneration. Spinocerebellar Ataxias” at the CBMSO, a centre comprising the “Universidad Autónoma de Madrid” and the CSIC, and that is also a member of the Centre for Biomedical Network Research on Rare Diseases (CIBERER).
The physician Díaz-Nido is a world authority on ataxias, having devoted more than ten years to studying Friedreich’s Ataxia at the molecular level and developing techniques to make gene therapy a reality. “The last ten years have witnessed great advances in gene therapy thanks to the contributions of hundreds of scientists worldwide. The last step is still pending for it to become a clinical option, but we are beginning to envisage that gene therapy will be possible for the treatment of such diseases of genetic origin,” maintains Díaz-Nido.
OVERCOMING THE BRAIN BARRIER
The brain is protected by the blood-brain barrier. This barrier serves to prevent toxic substances from entering the brain but it also obstructs the entry of therapeutic drugs. In this regard, collaboration with Ernest Giralt is critical. Prof. Giralt, head of the group “Design, synthesis and structure of peptides and proteins” and coordinator of the Chemistry and Molecular Pharmacology Programme at IRB Barcelona, has extensive experience and his expertise in peptide chemistry and drug delivery systems is internationally recognised. His laboratory has generated and satisfactorily tested a set of shuttle peptides able to cross the blood-brain barrier. “Our main goal is to adapt our shuttles to the vectors carrying the frataxin gene to enable them to cross the blood-brain barrier and then enter the nuclei of the cells of the nervous system,” explains Meritxell Teixidó, associate researcher at IRB Barcelona and responsible for this research line.
The joint research project begins in November 2013 and will last for three years. During this time, the team of scientists hopes to prepare the proof-of-concept that will allow the leap from basic lab research to preclinical trials in more sophisticated animal models and advancement towards a gene therapy for Friedreich’s Ataxia.
