Abstract

Objective/Background: To investigate the characteristics of vomiting in pediatric migraineurs and the relationship of vomiting with other migraine-related parameters. Methods: The cohort included children and adolescents with migraine attending a headache clinic of a tertiary pediatric medical center from 2010 to 2016. Patients were identified by a retrospective database search. Data were collected from medical files. The presence of vomiting was associated with background and headache-related parameters. Results: The study group included 453 patients, 210 boys (46.4%) and 243 girls (53.6%), of mean age 11.3 ± 3.7 years. Vomiting was reported by 161 patients (35.5%). On comparison of patients with and without vomiting, vomiting was found to be significantly associated with male gender (54% vs 42.1%, P <.018), younger age at migraine onset (8.0 ± 3. years vs 9.6 ± 3.7 years, P <.001), younger age at clinic admission (10.5 ± 3. years vs 11.6 ± 3.6 years, P =.002), higher rate of awakening headache (64.1% vs 38.7%, P <.001), lower headache frequency (10.5 ± 10.3 headaches/month vs 15.0 ± 11.7 headaches/month, P <.001), higher rate of episodic vs chronic migraine (67% vs 58.7%, P <.001), and higher rates of paternal migraine (24.1% vs 10.1%, P <.001), migraine in both parents (9.3% vs 3.1%, P =.007), and migraine in either parent (57.5% vs 45.5%, P =.02). Conclusions: The higher rate of vomiting in the younger patients and the patients with awakening pain may be explained by a common underlying pathogenetic mechanism of vomiting and migraine involving autonomic nerve dysfunction/immaturity. The association of vomiting with parental migraine points to a genetic component of vomiting and migraine. It should be noted that some of the findings may simply reflect referral patterns in the tertiary clinic.
