A 588-gene microarray analysis of the peripheral blood mononuclear cells of spondyloarthropathy patients
OBJECTIVES: To identify genes which are more highly expressed in the peripheral blood mononuclear cells (PBMC) of patients with spondyloarthropathy (SpA), rheumatoid arthritis (RA) and psoriatic arthritis (PsA), in comparison to normal subjects. METHODS: A 588-gene microarray was used as a screening tool to select a panel of such genes from PBMC of these subjects and of normal subjects. Results were then validated by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: The following genes were more highly expressed in arthritis patients than in normal subjects: macrophage differentiation marker MNDA (myeloid nuclear differentiation antigen), MRP8 and MRP14 (migratory inhibitor…
P124 The impact of the new American college of cardiology/american heart association (ACC/AHA) definition of hypertension on atherosclerotic vascular events in systemic lupus erythematosus
Background The 2017 ACC/AHA guidelines define hypertension as ≥130/80 mmHg instead of ≥140/90 mmHg. Studies in systemic autoimmune diseases, where blood pressure (BP) is fluctuating over time, were not considered. Our aim was to assess the impact of the new definition on the prevalence and incidence of atherosclerotic vascular events (AVEs) in systemic lupus erythematosus (SLE). Patients-Methods SLE patients with at least two years of follow-up and no previous AVEs were divided in three groups (≥140/90 mmHg, 130–139/80–89 mmHg and Results 1532 patients satisfied the inclusion criteria (88.1% females, mean age at baseline 36.2±14.3 years, mean disease duration 6.1±6.3 years). The prevalence …
