OBJECTIVE: To evaluate the biochemical and vascular aspects of pediatric chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME).

DESIGN: Cross-sectional clinical study.

SETTING: Tayside, Scotland, United Kingdom.

PARTICIPANTS: Twenty-five children with CFS/ME and 23 healthy children recruited from throughout the United Kingdom.

INTERVENTIONS: Participants underwent a full clinical examination to establish a diagnosis of CFS/ME and were asked to describe and score their CFS/ME symptoms. Biochemical markers were measured. Arterial wave reflection was estimated to assess systemic arterial stiffness.

MAIN OUTCOME MEASURES: Markers of oxidative stress and free radicals, C-reactive protein level, white blood cell apoptosis, and arterial wave reflection.

RESULTS: Children with CFS/ME had increased oxidative stress compared with control individuals (isoprostanes: 252.30 vs 215.60 pg/mL, P = .007; vitamin C, mean [SD]: 0.84 [0.26] vs 1.15 [0.28] mg/dL, P < .001; vitamin E, 8.72 [2.39] vs 10.94 [3.46] microg/mL, P = .01) and increased white blood cell apoptosis (neutrophils: 53.7% vs 35.7%, P = .005; lymphocytes: 40.1% vs 24.6%, P = .009). Arterial stiffness variables did not differ significantly between groups (mean augmentation index, -0.57% vs -0.47%, P = .09); however, the derived variables significantly correlated with total (r = 0.543, P = .02) and low-density lipoprotein (r = 0.631, P = .004) cholesterol in patients with CFS/ME but not in controls.

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.

Comments are most welcome! But please:

- No SPAM whatsoever, no supplements, no pharmaceuticals, no herbs or any other advertisements

- Absolutely no quack-doctors pushing their quack-BS websites (and if you are a quack, I will call you out)

- Be critical if you want to, but try to be coherent

Comments are moderated, because I am tired of Gerwyn-V99-The-Idiot and his moronic sockpuppets, and tired of the story of the two dogs, but I will try to publish everything else.

If you are not Gerwyn (and want to tell me something other than the story of the two dogs), then relax and write something! :-)
