Migraine, triptans, and the risk of developing rosacea : A population-based study within the United Kingdom - 17/08/13
Abstract |
Background |
Rosacea is a common skin disease, involving neurogenic inflammation and neurovascular dysregulation. Migraine has been associated with vascular changes and sterile inflammation. The 2 diseases have been associated over decades, but evidence is scarce. Triptans have vasoconstricting and antiinflammatory properties, but a potential impact of this drug class on rosacea remains uninvestigated.
Objective |
We sought to analyze the association between migraine or triptan exposure and the risk of developing rosacea within the United Kingdom.
Methods |
We conducted a case-control study using the United Kingdom–based General Practice Research Database. We identified patients with incident rosacea between 1995 and 2009 (cases), and matched 1 rosacea-free control subject to each case. We compared the prevalence of diagnosed migraine and exposure to triptans before the first-time rosacea diagnosis between cases and controls using multivariate conditional logistic regression.
Results |
Among 53,927 cases and 53,927 controls, we observed a small overall association between rosacea and migraine in women (adjusted odds ratio 1.22, 95% confidence interval 1.16-1.29), but not in men. This effect was somewhat more distinct in female migraineurs aged 50 to 59 years (odds ratio 1.36, 95% confidence interval 1.21-1.53). Female triptan users also revealed slightly increasing risk estimates with increasing age, with the highest odds ratio of 1.66 (95% confidence interval 1.30-2.10) in women aged 60 years or older.
Limitations |
This is a retrospective case-control study, for which a certain degree of bias and confounding cannot be ruled out.
Conclusions |
We observed a slightly increased risk for female migraineurs to develop rosacea, particularly in women with severe migraine aged 50 years or older.
