P3407Genetic predisposition and QRISK3 algorithm are promising cardiovascular risk scoring tools in young patients with axial spondyloarthritis (Bechterew's disease)
Abstract Introduction Major cardiovascular events (CVE) are frequently registered in patients with axial spondyloarthritis (axSpA) at age 35–55 years old. However, assessment of cardiovascular risk (CVR) in these age is complicated, as in pts <40 years conventional CVR scales (SCORE, ets.) are not recommended. Aim of the study To show capability of QRISK3 in assessment of CVR in young pts with axSpA and its association with gene polymorphisms, responsible for the inflammation and neoangiogenesis. Materials and methods The study included 46 pts 25–40 years old with axSpA (ASAS criteria 2009), achieved inactive disease on TNF-α inhibitors. AxSpA activity was assessed with ASDAS and BASDAI, CVR with QRISK3 (https://qrisk.org/three/). Gene polymorphisms to cytokines, responsible for inflammation and neoangiogenesis were measured (IL17A-197, IL17F7 His/Arg, IL17F-11139 c/g, TNF-863, TNF-308, TNF-238, IL1B-31, IL4–590, IL6–174, IL10–1082, IL10–592, VEGF-2578, VEGF936, MMP2–1306, MMP3–5A6A, and MMP9–1562). Results Mean age of axSpA pts was 32.5±3.87 years, 36 (78.3%) pts were male, axSpA duration 8.71±4.72 years, duration of the treatment 3.1±2.4 years, ASDAS 1.95±1.23, BASDAI 1.4±0.8, QRISK3 score 1.18±1.64%. 34 (75.6%) of the pts had a low CVR and 11 (23.9%) had increased CVR. All the patients with increased CVR had strong associations with some alleles of TNFα, IL17F and IL6, p<0.ehz745.0282 for all the correlations (table 1). Interrelations of CVR with another gene polymorphisms were not significant (R<0.25, p≥0.05, data are not present).

Similar gene polymorphisms in IL-6, IL17F, and TNF-α are strongly associated with increased CVR. QRISK3 and gene polymorphisms could be promising tools in CVR assessment in axSpA, acceptable in any age. Conflict of interests Not declared.
