ABSTRACT
The association between SLE and composite stroke, ischaemic stroke and haemorrhagic stroke remains incompletely understood. This meta-analysis aims to assess the risk of stroke in patients with SLE.
METHODS: Data sources included PubMed, Embase, the Cochrane Library and reference lists of included studies. This meta-analysis included cohort studies evaluating whether stroke risk is associated with SLE. The risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). Risk ratios (RRs) with 95% CIs were pooled using a random-effects model, and publication bias was assessed with funnel plots and Egger's test.
RESULTS: A total of 25 cohort studies involving 5 220 837 individuals were included in this meta-analysis, which were published between 2001 and 2026. The pooled analysis demonstrated a significantly increased risk of stroke in patients with SLE (RR of 2.60, 95% CI 2.21 to 3.05, I²=97.9%, p<0.001). The risk of composite stroke (RR of 2.83, 95% CI 2.25 to 3.57, I²=98.0%, p<0.001), ischaemic stroke (RR of 2.34, 95% CI 1.75 to 3.12, I²=97.6%, p<0.001) and haemorrhagic stroke (RR of 2.66, 95% CI 1.57 to 4.49, I²=96.2%, p<0.001) was also increased in SLE. Despite the large heterogeneity, the sensitivity analysis indicated that the results were robust, and there was little evidence of publication bias.
CONCLUSION: The risk of composite stroke, ischaemic stroke and haemorrhagic stroke is increased in SLE.
