Cutaneous Allodynia and Its Risk Factors in Korean Patients with Migraine: A Survey of Two Tertiary Care Hospitals
Kim, Sun-Young / Park, Sung-Pa
Aims: To measure the prevalence of cutaneous allodynia in Korean patients with migraine and to characterize the differential risks of migraine-associated factors and psychiatric disorders in its development.
Methods: The study included consecutive patients with migraine who visited headache clinics at two tertiary care hospitals. Questionnaires including the 12-item Allodynia Symptom Checklist (ASC-12) and the Migraine Disability Assessment (MIDAS) were administered to the patients. The Mini International Neuropsychiatric Interview-Plus, Version 5.0.0 (MINI), was performed to diagnose current major depressive disorder (MDD) and current generalized anxiety disorder (GAD). To determine the predictive factors of cutaneous allodynia, a two-step logistic regression model was used.
Results: A total of 332 patients were eligible for the study. Chronic migraine (CM) was present in 140 patients (42.2%). Current MDD and current GAD were identified in 73 (21.9%) and 59 patients (17.7%), respectively. Cutaneous allodynia was present in 48 patients (14.5%). Univariate analyses indicated that cutaneous allodynia was associated with female gender, CM, medication overuse headache, headache intensity, photophobia, phonophobia, MIDAS grade, current MDD, and current GAD. Multivariate analyses revealed that current MDD was the strongest risk factor for cutaneous allodynia (adjusted odds ratio [AOR] = 4.552; 95% confidence intervals [CI] = 2.300-9.007; P = .000), followed by CM (AOR = 3.666; 95% CI = 1.787-7.521; P = .000) and photophobia (AOR = 2.707; 95% CI = 1.340-5.469; P = .005).
Conclusion: Korean patients with migraine have a low prevalence of cutaneous allodynia. Both depression and migraine-associated features are important factors in the occurrence of cutaneous allodynia.
