Antiphospholipid antibodies in migraine
Abstract:
We studied the presence of serum antiphospholipid antibodies (APA) in 35 patients with migraine and 75 controls. None of the controls showed APA, while we found these antibodies in five patients out of the 35 studied (p = 0.003). The clinical features of migraineurs with APA were similar to those of patients without them. After a follow-up of one to two years, no patient suffered any neurological complications or developed any clinical features that would suggest the presence of autoimmune disease. Our results suggest that APA are not prominent in the pathogenesis of migraine attacks, or significant in the course of otherwise healthy migraine patients.
Insights
Antiphospholipid antibodies (APA) were found in 14% of migraine patients but not in controls. These antibodies did not appear to influence migraine clinical features or long-term outcomes.
Area of Science:
- Neurology
- Immunology
- Rheumatology
Background:
- Migraine is a common neurological disorder.
- Antiphospholipid antibodies (APA) are associated with autoimmune conditions and thrombosis.
- The role of APA in migraine pathogenesis is not well understood.
Purpose of the Study:
- To investigate the prevalence of serum APA in migraine patients.
- To compare APA levels between migraine patients and healthy controls.
- To evaluate the clinical significance of APA in migraine.
Main Methods:
- Serum samples were collected from 35 migraine patients and 75 controls.
- Antiphospholipid antibodies (APA) were measured using serological assays.
- Clinical features and follow-up data were collected for all participants.
Main Results:
- APA were detected in 5 out of 35 migraine patients (p = 0.003).
- No APA were found in the 75 controls.
- Clinical characteristics and one-to-two-year follow-up showed no significant differences or complications related to APA presence.
Conclusions:
- APA are present in a subset of migraine patients.
- APA do not appear to be a significant factor in the pathogenesis or long-term course of migraine in otherwise healthy individuals.
- Further research may be needed to clarify the specific role, if any, of APA in certain migraine subtypes.
