Background:
Exposure to Migraine may be one of the risk factors for the onset of rheumatoid arthritis (RA), while the relationship between the two is debatable. In this study, the connection between migraine and the risk of RA was investigated using a systematic review and meta-analysis of the pertinent literature.
Methods:
Up to July 2022, the PubMed, EMBASE, Web of Science (WOS), and scopus databases were employed to search for observational studies on the risk of RA in migraineurs. The effect sizes were pooled using a random-effects model or a fixed-effects model.
Results:
Out of 2345 records, 5 studies (3 case and control studies and 2 cohort studies) were identified and included in the meta-analysis. According to a pooled analysis, migraine sufferers had a higher chance of developing RA (pooled adjusted effect estimate: 1.94, 95% confidence interval: 1.74-2.17; p < 0.01).
Conclusions:
Migraine can be legitimately regarded as a risk factor for RA since this study demonstrated a relationship between migraine and RA. This conclusion should be treated with caution due to low power and precision. Rigorous design and larger sample sizes of studies are needed to verify the findings.
Insights
Migraine may increase the risk of developing rheumatoid arthritis (RA). This meta-analysis found migraine sufferers have a higher chance of RA onset, but more research is needed for confirmation.
Area of Science:
- Rheumatology
- Neurology
- Epidemiology
Background:
- The potential link between migraine and rheumatoid arthritis (RA) risk is debated.
- Investigating migraine as a risk factor for RA onset is crucial for understanding disease etiology.
Purpose of the Study:
- To systematically review and meta-analyze existing literature to determine the association between migraine and the risk of developing rheumatoid arthritis (RA).
Main Methods:
- A comprehensive literature search was conducted across PubMed, EMBASE, Web of Science, and Scopus databases up to July 2022.
- Included observational studies were analyzed using a random-effects or fixed-effects model for pooled effect size estimation.
Main Results:
- Five studies, including 3 case-control and 2 cohort studies, were identified from 2345 records.
- Migraineurs demonstrated a significantly increased risk of developing RA, with a pooled adjusted effect estimate of 1.94 (95% CI: 1.74-2.17; p < 0.01).
Conclusions:
- Migraine is suggested as a potential risk factor for rheumatoid arthritis (RA).
- The findings indicate a statistically significant association, but require cautious interpretation due to study limitations.
- Further rigorous research with larger sample sizes is recommended to validate these findings and clarify the relationship.
