Abstract:
Objective To analyze the clinical characteristics of children with cyclic vomiting syndrome (CVS), summarize the clinical experience, and improve the awareness,diagnosis and treatment level of CVS.Methods The clinical data and results of long-term follow-up of the children with CVS were collected and analyzed from 1995 to 2009 in our department.Results Forty-six children were enrolled in the study, including 22 boys and 24 girls.Mean onset age was 4.5 years(ranged from 1 to 11 years)and the mean age at final diagnosis was 8.5 years (ranged from 4.5 to 14.5 years).Sixty-six and seventy-four percent of patients had family history of migraine and motional sickness respectively,whereas 83% patients had triggers.The clinical manifestation of CVS was severe episodic vomiting.The episodes had a rapid onset and sudden ending,persisted for several hours to days,and were separated by symptom-free intervals.The incidental symptoms were pallor, lethargy,intractable nausea,abdominal pain,headache,photophobia and dizzy.Twenty-nine patients diagnosed were followed up for 5 years at average.Five patients were treated with valproate,4 with cyproheptadine, 5 with cyproheptadine and valproate,5 with amitriptyline,cyprohep tadine and valproate,and 3 with cyproheptadine and flunarizine.All treated patients recovered mean 10 months(1.5 months to 2 years) years later and displayed the reduced number of episodes or the severity of episodes except 3 patients.Twenty-eight percent (8/29) of patients progressed to migraine headaches.Conclusion CVS is a relatively common disease in children and awareness of the condition should be increased.CVS should be considered when patients had recurrent vomitting and were completely healthy between the two episodes after excluding other pathological conditions.
