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