Abstrakt:	Objective: To evaluate transforming growth factor beta (TGF-β) in patients with cervical artery dissection (CeAD). Material and Methods: TGF-β was studied by enzyme immunoassay in 74 of 336 patients with CeAD observed at the Research Center of Neurology (Moscow) from 2000 to 2021. The average patient's age at the time of TGF-β study was 41.6±9.8 years; the proportion of women was 51%. TGF-β was studied in the first month of the disease ( n =9), for 2-3 months ( n =12) and at a later period (mean - 4.3±5.03 years) ( n =53). The control group consisted of 20 healthy volunteers, matched for age and sex. Dissection occurred in internal carotid artery (ICA) ( n =42), vertebral artery (VA) ( n =29), ICA+VA ( n =3) and involved 1 artery ( n =58) or 2-3 arteries ( n =16). Clinical manifestations included ischemic stroke (IS) ( n =49), isolated cervical-cephalic headache ( n =23), lower cranial nerve palsy ( n =2). Pathological CeAD tortuosity was detected by angiography in 13 patients, and a dissecting aneurysm in 15 patients. Results: TGF-β1 and TGF-β2 were elevated in patients with CeAD patients compared with the control: TGF-β1 - 4990 [3950; 7900] pg/ml vs. 3645 [3230; 4250] pg/ml, p =0.001; TGF-β2 - 6120 [4680; 7900] pg/ml vs. 3155 [2605; 4605] pg/ml, p =0.001. The highest TGF-β1 and TGF-β2 levels were noted at 2-3 months of the disease. There was no correlation between the TGF-β level and various clinical and angiographic parameters. Conclusion: Increased TGF-β level confirms that CeAD patients have connective tissue disorder that underlies the arterial wall weakness. A higher TGF-β level at 2-3 months of CeAD seems to be connected with an active reparative process in arterial wall after dissection. TGF-β can be used as a biomarker of connective tissue dysplasia in patients with CeAD.
