Discrepancies between rapid3 and das28 in rheumatoid arthritis patients in remission or low disease activity receiving tnf inhibitors: what is the role of the inflammation biomarkers?

Background: Patients with rheumatoid arthritis (RA) have been associated to higher morbidity and mortality due to cardiovascular events. The impact of atorvastatin and colchicine in reducing these complications has been evaluated without comparative studies of these drugs in RA patients. We assess whether atorvastatin is superior to colchicine in cardiovascular risk markers (high-sensitivity troponin I (hs-cTnI), echocardiographic abnormalities and inflammatory cytokine) in patients with RA Objectives: The primary objective was to compare the initial and final levels of hs-cTnI with both treatments. Secondary objectives: Describe initial echocardiographic abnormalities, compare changes in these alterations with treatment, evaluate factors associated with a higher level of hs-cTnI and echocardiographic abnormalities, compare changes in serum levels of inflammatory cytokines (TNF, IL 8, IL 1β, IL 6, IL 10, IL 12p70) and values of lipid profile Methods: Prospective randomized pilot study, blinded for cardiologist and rheumatologist, with patients with RA and severe disease activity (DAS 28\u003e 5.1), without known heart disease, kidney disease or previous use of atorvastatin and / or colchicine. Patients were assigned according to randomization in two groups: atorvastatin 40 mg/day or colchicine with an initial dose of 0.75 mg/day titled according to tolerance up to a maximum dose of 1.5 mg/day, both were received for four weeks. NCT04056039 Results: Recruitment of September 2018 to August 2019, 60 participants had undergone randomization (30 in each group) with a median age 48. The duration of follow-up from randomization was 28 days in each group. Participants were followed by weekly telephone contact to assess of adherence treatment. A detected value of hs-cTnI was found in all patients, initial value in the atorvastatin group: Median 1ng /L, IQR 1-2 and final: Median 1ng /L, IQR 1-3 vs initial value in the colchicine group: 1ng /L, IQR 1-2 and final: 1ng /L, IQR1-2 p = 0.67. Echocardiographic abnormalities in 46 patients (76.66%); 63.33% diastolic dysfunction, 15% tricuspid regurgitation and 11.66% left ventricular hypertrophy. There were changes in initial and final diastolic dysfunction in the atorvastatin group from 19 to 9 vs colchicine 19 to 12 p = 0.05, 95% CI 0.49-0.82. Correlation of initial hs-cTnI with age p Conclusion: We do not observe substantial differences in decrease in hs-cTnI with atorvastatin and colchicine, a prospective study of 222 patients is required to avoid β-type error. Echocardiographic abnormalities in 76% of patients showed a greater decrease in diastolic dysfunction in the atorvastatin group, as well as lower cholesterol and LDL-cholesterol levels, thus, as a tendency to falling of TNF and IL 1β in this group References: [1]Liao KP, Solomon DH.
