Abstract

AbstractBackground

To assess the risk of incident cardiovascular disease in patients with primary Sjögren's syndrome, overall and stratified by Ro/SSA and La/SSB autoantibody status.

Methods

A cohort of patients with primary Sjögren's syndrome in Sweden (n = 960) and matched controls from the general population (n = 9035) were included, and data extracted from the National Patient Register to identify events of myocardial infarction, cerebral infarction and venous thromboembolism. Hazard ratios were estimated using cox proportional hazard regressions.

Results

During a median follow‐up of 9.5 years, the overall hazard ratio (HR) was 1.6 (95% CI 1.2–2.1) for myocardial infarction, 1.2 (95% CI 0.9–1.7) for cerebral infarction and 2.1 (95% CI 1.6–2.9) for venous thromboembolism. Patients positive for both Ro/SSA and La/SSB autoantibodies had a substantially higher risk of cerebral infarction (HR 1.7, 95% CI 1.0–2.9) and venous thromboembolism (HR 3.1, 95% CI 1.9–4.8) than the general population. These risks were not significantly increased in Ro/SSA‐ and La/SSB‐negative patients. Among autoantibody‐positive patients, the highest HR of cerebral infarction was seen after ≥10 years disease duration (HR 2.8, 95% CI 1.4–5.4), while the HR for venous thromboembolism was highest 0–5 years after disease diagnosis (HR 4.7, 95% CI 2.3–9.3) and remained high throughout disease duration.

Conclusions

Primary Sjögren's syndrome is associated with a markedly increased risk of cardiovascular disease and the presence of Ro/SSA and La/SSB autoantibodies identify the subgroup of patients carrying the highest risk. These findings suggest that monitoring and prevention of cardiovascular disease in this patient group should be considered.

<title>Background</title>
<p>To assess the risk of incident cardiovascular disease in patients with primary Sjögren's syndrome, overall and stratified by Ro/

<sec id="joim12941-sec-0002">
<title>Methods</title>
<p>A cohort of patients with primary Sjögren's syndrome in Sweden (
<italic>n</italic>
 = 960) and matched controls from the general population (
<italic>n</italic>
 = 9035) were included, and data extracted from the National Patient Register to identify events of myocardial infarction, cerebral infarction and venous thromboembolism. Hazard ratios were estimated using cox proportional hazard regressions.</p>
</sec>
<sec id="joim12941-sec-0003">
<title>Results</title>
<p>During a median follow‐up of 9.5 years, the overall hazard ratio (
<styled-content style="fixed-case" toggle="no">HR</styled-content>
) was 1.6 (95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
1.2–2.1) for myocardial infarction, 1.2 (95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
0.9–1.7) for cerebral infarction and 2.1 (95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
1.6–2.9) for venous thromboembolism. Patients positive for both Ro/
<styled-content style="fixed-case" toggle="no">SSA</styled-content>
and La/
<styled-content style="fixed-case" toggle="no">SSB</styled-content>
autoantibodies had a substantially higher risk of cerebral infarction (
<styled-content style="fixed-case" toggle="no">HR</styled-content>
1.7, 95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
1.0–2.9) and venous thromboembolism (
<styled-content style="fixed-case" toggle="no">HR</styled-content>
3.1, 95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
1.9–4.8) than the general population. These risks were not significantly increased in Ro/
<styled-content style="fixed-case" toggle="no">SSA</styled-content>
‐ and La/
<styled-content style="fixed-case" toggle="no">SSB</styled-content>
‐negative patients. Among autoantibody‐positive patients, the highest
<styled-content style="fixed-case" toggle="no">HR</styled-content>
of cerebral infarction was seen after ≥10 years disease duration (
<styled-content style="fixed-case" toggle="no">HR</styled-content>
2.8, 95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
1.4–5.4), while the
<styled-content style="fixed-case" toggle="no">HR</styled-content>
for venous thromboembolism was highest 0–5 years after disease diagnosis (
<styled-content style="fixed-case" toggle="no">HR</styled-content>
4.7, 95%
<styled-content style="fixed-case" toggle="no">CI</styled-content>
2.3–9.3) and remained high throughout disease duration.</p>

<title>Conclusions</title>
<p>Primary Sjögren's syndrome is associated with a markedly increased risk of cardiovascular disease and the presence of Ro/
<styled-content style="fixed-case" toggle="no">SSA</styled-content>
and La/
<styled-content style="fixed-case" toggle="no">SSB</styled-content>
autoantibodies identify the subgroup of patients carrying the highest risk. These findings suggest that monitoring and prevention of cardiovascular disease in this patient group should be considered.</p>
