Scientists at the University of Dundee study found abnormalities in the white blood cells of children with ME/CFS, suggesting they had been fighting off infection.
About 150,000 people in the UK have ME/CFS, 15,000 of whom are children.
The condition is characterised by physical and mental exhaustion following normal activities. Symptoms can include muscle pain, sore throat, tender lymph nodes, multi-joint pain and headaches.
In the study, funded by ME Research UK and The Young ME Sufferers (Tymes) Trust, 25 children aged between seven and 14 with ME/CFS were assessed, along with 23 children of a similar age in a control group.
The report, published in the Archives of Paediatrics and Adolescent Medicine, said abnormalities were found in the blood of all the children with ME/CFS.
The results were similar to those previously identified in adults with the condition.
Samples taken from youngsters with ME/CFS contained higher than normal levels of free radicals - molecules that can damage cells, tissues and organs.
The above was reported in the BBC News see here
Below is from the original study see here
Conclusions Biomedical anomalies seen in adults with CFS/ME—increased oxidative stress and increased white blood cell apoptosis—can also be observed in children with clinically diagnosed CFS/ME compared with matched controls. Unlike in their adult counterparts, however, arterial stiffness remained within the reference range in these pediatric patients.
Discussions on the BBC Breakfast news this morning revolve around this indicating a virus - I could be wrong but the study does not differentiate as to the cause of infection so assumption that is viral rather than bacterial would appear premature.
How many of these children were tested thoroughly for such as Lyme Disease and the many known co infections that are being found to go hand in hand with Tick Borne illness.
Nevertheless it is excellent to see this research that takes us one step closer to finding the cause of ME/CFS in some patients what a pity the media didn't pay as much attention to the research findings of XMRV and MLV's .
