Estudian biomarcadores biológicos en SFC pediátrico

Mensaje por elipoarch » 20 Ago 2015, 12:38



En Australia inician un estudio para encontrar biomarcadores para el SFC pediátrico. Todos sabemos cómo es de difícil asegurarse de que un niño tiene SFC, a no ser que esté extremadamente grave y encamado, así que éste grupo de investigadores ha iniciado un estudio (25 adolescentes enfermos y 25 controles sanos) mediante pruebas de neuroimagen [supongo que hablan de SPECT] para determinar si un niño o adolescente sufre SFC/EM o no. Para ello, harán una prueba basal (en reposo) y otra prueba tras 90 minutos de actividades y ejercicios similares a los que se realizan en la escuela. De este modo, pueden apreciarse diferencias en el cerebro tras el esfuerzo mental. Es la misma prueba que hace el Dr. Alegre (y supongo que García Quintana también) para reforzar el caso ante los tribunales.
Por supuesto, éste estudio será pagado por una asociación de enfermos, en este caso, ME Research, UK, del Reino Unido. Está claro que si los enfermos no nos movemos, aquí no se mueve nadie :evil:



[t]Neurological biomarkers in paediatric ME/CFS[/t]

Principal Investigators
Dr Sarah Knight and colleagues
Institution
Murdoch Children’s Research Institute, The Royal Children’s Hospital, University of Melbourne, Melbourne, Australia
Funding
ME Research UK

Background and aim
There are few, if any, good estimates of the numbers of children affected by ME/CFS. Assuming rough prevalence figures of 60 to 70 cases per 100,000, however, it is likely that around 9,000 people under the age of 16 in the UK have this diagnosis. As the report to the Chief Medical Officer in 2002 made clear, this illness “represents a substantial problem in the young” and “potentially threatens physical, emotional, and intellectual development of children and young people, and can disrupt education and social and family life, at a particularly vulnerable time of life”. For these reasons, scientific investigations of ME/CFS in young people are urgently needed, and may well result in important findings. ME Research UK-funded researchers at the University of Dundee, for example, have found biomedical anomalies in children with ME/CFS — increased oxidative stress and increased white blood cell apoptosis — similar to those seen in adults with the illness, and have shown that the quality of life of these children is profoundly reduced compared with their healthy counterparts.

There is now very good evidence of difficulties with memory, concentration/attention, and information processing in adults with ME/CFS. The memory problems include difficulties with visual & verbal memory, short-term and long-term recall, and mental clouding (“brain fog”). These have significant effects on daily functioning at home or work, as most patients know. Much less is known about these neurocognitive difficulties in youngsters, particularly the role of mental exertion in worsening these symptoms. In fact, advanced structural and functional neuroimaging techniques have only rarely been applied to understanding the impact of ME/CFS on the function of the developing brain. For this reason, ME Research UK has awarded funding to Dr Sarah Knight and colleagues of the Murdoch Children’s Research Institute in Melbourne to examine how the brain and its underlying functioning responds to mental exertion in adolescents with ME/CFS, using a variety of neuroimaging techniques.

Dr Knight and colleagues lead a growing paediatric ME/CFS clinical research program – the only program of its kind in Australia, and one of the very few in the world – which is dedicated to improving the lives of these children and adolescents. For this study, 25 adolescents diagnosed using the Canadian Clinical Criteria adapted for paediatricians and 25 matched healthy controls will have baseline functional neuroimaging, followed by 90 minutes of structured effortful thinking and learning activities similar to school work or home work, after which another brain scan will take place. The aim is to combine sophisticated brain imaging techniques with cognitive assessments to examine underlying brain function in these adolescent patients who are suffering from ME/CFS at a critical time in their development and are at risk of significant long-term consequences affecting their academic and social activities.

Gracias Eli! Muy interesante :thumbup:

Es importante que se hagan este tipo de estudios y que se visibilice a l@s pacientes más jóvenes. Yo enfermé siendo adolescente y creo que es un grupo especialmente vulnerable. Es muy duro crecer con esto y ver tu vida pasar, sin haber podido ni siquiera forjar una base laboral.

Creo también que la estimulación de 90 minutos con actividades similares a las del colegio, es muy adecuada. El Spect estimulado que me hice con la Dra. Quintana fue muy flojo ( al menos en mi caso). Fueron apenas 15 minutos de ejercicios muy sencillitos. Aún así me salió una hipoperfusión leve pero sólo escribiendo este mensaje ya estoy realizando mayor esfuerzo cognitivo.

Me parece fundamental en este tipo de pruebas intentar recrear las condiciones fisiológicas a las que nos exponemos diariamente para poder pillar las anomalías "in fraganti".
