Summary
Thyroid autoimmunity and elevated thyroid peroxidase antibody (TPOAb) levels are linked to spontaneous cervicocranial arterial dissection (SCCAD). TPOAb also shows a specific association with dissection location in the vertebral artery segments.
Area of Science:
- Neurology
- Immunology
- Vascular Medicine
Background:
- Immune-mediated mechanisms are implicated in spontaneous cervicocranial arterial dissection (SCCAD).
- The link between thyroid autoimmunity and SCCAD is debated, and its effect on dissection location is unevaluated.
Purpose of the Study:
- To investigate the association between thyroid autoimmunity and SCCAD.
- To evaluate the correlation between thyroid autoimmunity and the anatomical distribution of dissections in SCCAD patients.
Main Methods:
- Retrospective case-control study (164 SCCAD patients, 164 controls).
- Multivariate logistic regression, propensity score matching, and sensitivity analyses were used.
- Examined the impact of thyroid autoantibodies and TPOAb levels on SCCAD and dissection location.
Main Results:
- SCCAD patients had significantly higher rates of thyroid autoimmunity positivity (OR 6.715) and elevated TPOAb levels (OR 5.999) compared to controls.
- Elevated TPOAb levels were positively associated with V4 segment involvement (OR 7.663) and inversely associated with V3 segment involvement (OR 0.065).
- Sensitivity analyses confirmed these segment-specific associations.
Conclusions:
- Thyroid autoimmunity and elevated TPOAb are independently associated with SCCAD.
- TPOAb levels show a novel segment-specific association with vertebral artery dissections (V4 positive, V3 inverse).
