Does severe nutcracker phenomenon cause pediatric chronic fatigue?
BACKGROUND
In the past five years we experienced 9 fatigued disabled children who were intermittently or persistently absent from school.


METHODS
They had been suspected to be burdened with psychosomatic disorders, having orthostatic hypotension, postural tachycardia, or other autonomic dysfunction symptoms.


RESULTS
Investigating the cause of moderate orthostatic proteinuria in some of them, we found by chance severe typical nutcracker phenomenon (NC), which was present in all 9 children complaining of chronic fatigue.


CONCLUSIONS
Their symptoms filled the criteria of chronic fatigue syndrome or idiopathic chronic fatigue (CFS/CF). An association between severe NC and autonomic dysfunction symptoms in children with CFS/CF has been presented.
