Session Time: 9:00AM-11:00AM
Background/Purpose: Rheumatologists need to develop primary prevention strategies for cardiovascular disease (CVD) in rheumatoid arthritis (RA) patients. We reported tofacitinib (Tofa) plus methotrexate improved left ventricular mass index (LVMI) in patients with rheumatoid arthritis. How about tofacitinib monotherapy? To study the effect of Tofa monotherapy (MTX) on LV morphology and function in conventional DMARDs resistant active RA patients, in a cohort study design.
Methods: RA patients were eligible if they had active disease despite treatment with conventional DMARDs. Consecutive 21 patients with moderate to severe active RA patients (DAS28>3.2) despite conventional DMARDs were received Tofa monotherapy. LV morphology and function was assessed with cardio-MRI at baseline and 24 weeks follow-up. Cardiovascular risk factors and clinical data were collected at regular visits.
Results: 19 patients completed 24 weeks. Left ventricular mass index (LVMI) was attenuated significantly by Tofa (week 0-week24, −10.02±4.8 g/m2; p=0.02). Cardiac output (CO) was attenuated significantly by Tofa (week 0-week24,-0.65 ± 0.9l/min). DAS28 and CRP improved significantly by Tofa (week 0-week24; DAS28: -2.16±0.95; CRP: 15.1±5.7 mg/l) (p<0.05). Surprisingly, the change of disease activity (DAS 28 and CRP) is no correlation with the change of LVMI or CO in this study. Observationally, 2 cases significantly improved right ventricular mass as well as left ventricular mass (20 % improved right ventricular mass index from baseline).
Conclusion: Tofa monotherapy improved LVMI and CO in active RA despite MTX. Tofa monotherapy improves LVMI and CO independently of its effects on disease activity. Tofa might be improved right ventricular mass. JAK-STAT pathway might be an important role of LV hypertrophy. Tofa, JAK-STAT pathway blocking, may prevent cardiovascular morbidity and mortality in RA.
