RESUMEN
OBJECTIVE: Migraine is a chronic condition with complex pathophysiology. Although immunologic disturbances have been linked to migraine, only few attempts have been made to assess the possibility of allergic rhinitis as a worsening factor of migraine in adults. This survey aimed to compare migraine disability between adult migraineurs with and without current allergic rhinitis. METHODS: This cross-sectional study comprised 118 adult migraineurs who were consecutively assisted at an outpatient clinic. After ordinary neurological evaluation, participants were evaluated for headache disability using the Migraine Disability Assessment (MIDAS). The presence of current allergic rhinitis, allergic rhinoconjunctivitis and seasonal allergic rhinitis was scored for each participant according to the International Study of Asthma and Allergies in questionnaire. RESULTS: There was no significant difference between the MIDAS scores of those with current allergic rhinitis, allergic rhinoconjunctivitis, or seasonal allergic rhinitis and nonatopic migraineurs. The disability caused by allergic symptoms also did not influence the MIDAS scores of patients with allergic rhinitis. The frequency of headache days during the last three months was higher in the subset of patients without allergic rhinitis (median and interquartile range 12 [8-19.2] vs. 8 [4-14]; p = 0.03). CONCLUSIONS: Our results suggest that current allergic rhinitis, allergic rhinoconjunctivitis, and seasonal allergic rhinitis are not related to headache disability in adults with episodic migraine.

RESUMO A migrânea é uma condição dolorosa crônica com fisiopatologia complexa. Apesar de disfunções imunológicas já terem sido ligadas à migrânea, poucas foram as tentativas, na literatura, de se avaliar a possibilidade da rinite alérgica como um fator agravante da migrânea em adultos, tornando a questão ainda não esclarecida. Objetivo Esta pesquisa visou comparar a incapacidade da migrânea em adultos com e sem rinite alérgica. Métodos Este estudo transversal incluiu 118 adultos com migrânea consecutivamente atendidos em uma clínica ambulatorial. Após o exame neurológico usual, os participantes foram avaliados com relação à incapacidade gerada pela cefaleia com o Migraine Disability Assessment (MIDAS), assim como para a presença atual de rinite alérgica, rinoconjuntivite alérgica e rinite alérgica sazonal de acordo com o questionário do International Study of Asthma and Allergies in Childhood (ISAAC). Resultados Não houve diferença nos escores do MIDAS entre migranosos com e sem alérgica, rinoconjuntivite alérgica e rinite alérgica sazonal. A incapacidade causada pelos sintomas alérgicos também não influenciou os escores do MIDAS dos pacientes com rinite alérgica. A frequência de dias com cefaleia durante os últimos 3 meses foi maior no subgrupo de pacientes sem rinite alérgica (mediana e intervalo interquartil 12 [8-19,2] vs. 8 [4-14]; p = 0,03). Conclusões Os resultados sugerem que rinite alérgica, rinoconjuntivite alérgica e rinite alérgica sazonal não estão relacionadas à incapacidade por cefaleia em pacientes adultos com migrânea episódica.
