| description | Objective – to investigate cerebrovascular reactivity (CVR) depending on rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity in hypertensive patients with rheumatoid arthritis (RA).Subjects and methods. A single cross-sectional study included 61 patients (mean age 59.8±7.7 years; 6 men and 55 women) with combined RA and grade 1–2 hypertension (HTN). The duration of RA was 11.2±7.4 years. The duration of HTN was 12.1±8.6 years. All patients were treated with methotrexate. RA patients were categorized into RF/ACPA seronegative and RF/ACPA seropositive subgroups. CVR was evaluated by bilateral transcranial Doppler sonography of the middle cerebral arteries (MCA) in a hyperoxic test (O2 CVR) and in a hypercapnic test (CO2 CVR). We measured MCA mean blood flow velocity (Vmn), time average maximal blood flow velocity (TAMX), peak systolic velocity (Vps) at baseline, within 2 minutes of 100% oxygen inhalation and within 3 minutes of recovery phase (hyperoxic test). We calculated the following indicators for assessing CVR: index changes of flow velocity mean (IFVm), speed modification of velocity (SMFVm) and normalized answer of reserve (NAR). Then, according to the same scheme, we performed a hypercapnic test with the inhalation of a 4% mixture of carbon dioxide with air. Values are presented as Me [Q1 ; Q3 ].Results and discussion. Hypertensive patients with RA had a decrease in response power of MCA blood flow to hyperoxia. RF-seropositive RA patients had a more pronounced decrease in the power of the response to hyperoxia compared with RF-seronegative RA patients. The values of IFVm in the hyperoxic test were –13.4 [–19.9; –0.9] versus –16.2 [–22.7; –13.4]% (р=0.0453), respectively. ACPA-seropositive RA patients had not only a more pronounced decrease in the power of the response of MCA blood flow to hyperoxia, but also a more pronounced slowdown in the response velocity of MCA blood flow to hyperoxia compared with ACPA-seronegative RA patients. The values of IFVm in the hyperoxic test were –9.74 [–15.9; 2.84] versus –20.9 [–25.0; –14.7]% (р=0.0062), the values of SMFVm were –0.05 [–0.09; 0.02] versus –0.09 [–0.20; –0.05] sm/s2 (р=0.0488) respectively. Combined RA and HTN patients had a decrease in response power of MCA blood flow to hypercapnia. However, no statistical differences were found in the state of CO2 CVR between patients with seropositive RA and seronegative RA.Conclusion. Hypertensive patients with seropositive RA have a more pronounced O2 CVR disorder in compared to seronegative RA patients. |
