Disease-modifying antirheumatic drug use and the risk of incident hyperlipidemia in patients with early rheumatoid arthritis: a retrospective cohort study.

ABSTRACT: To compare the risk of incident hyperlipidemia in early rheumatoid arthritis (RA) patients after initiation of various disease-modifying antirheumatic drugs (DMARDs).We conducted a cohort study using insurance claims data (2001-2012) in early RA patients. Early RA was defined by the absence of any RA diagnosis or DMARD prescriptions for 12 months. Four mutually exclusive groups were defined based on DMARD initiation: tumor necrosis factor ? (TNF?) inhibitors ± nonbiologic (nb) DMARDs, methotrexate (MTX) ± nonhydroxycholorquine nbDMARDs, hydroxychloroquine ± non-MTX nbDMARDs, and other nbDMARDs only. The primary outcome was incident hyperlipidemia, defined by a diagnosis and a prescription for a lipid-lowering agent. For the subgroup of patients with laboratory results available, change in lipid levels was assessed. Multivariable Cox proportional hazard models and propensity score (PS) decile stratification with asymmetric trimming were used to control for confounding.Of the 17,145 early RA patients included in the study, 364 developed incident hyperlipidemia. The adjusted hazard ratios (HRs; 95% confidence intervals [95% CIs]) for hyperlipidemia were 1.41 (95% CI 0.99, 2.00) for TNF? inhibitors, 0.81 (95% CI 0.63, 1.04) for hydroxychloroquine, and 1.33 (95% CI 0.95, 1.84) for other nbDMARDs compared with MTX in the full cohort, while HRs for the PS trimmed cohort were 1.18 (95% CI 0.80, 1.73), 0.75 (95% CI 0.58, 0.98), and 1.41 (95% CI 1.01, 1.98), respectively. In the subgroup analysis, hydroxychloroquine use showed significant reduction in low-density lipoprotein (-8.9 mg/dl, 95% CI -15.8, -2.0), total cholesterol (-12.3 mg/dl, 95% CI -19.8, -4.8) and triglyceride levels (-19.5 mg/dl, 95% CI -38.7, -0.3) from baseline compared with MTX.Use of hydroxychloroquine may be associated with a lower risk of hyperlipidemia among early RA patients.

Project description:OBJECTIVES:To determine whether patients with early rheumatoid arthritis (ERA) have cardiovascular disease (CVD) that is modifiable with disease-modifying antirheumatic drug (DMARD) therapy, comparing first-line etanercept (ETN) + methotrexate (MTX) with MTX strategy. METHODS:Patients from a phase IV ERA trial randomised to ETN+MTX or MTX strategy±month 6 escalation to ETN+MTX, and with no CVD and maximum one traditional risk factor underwent cardiovascular magnetic resonance (CMR) at baseline, years 1 and 2. Thirty matched controls underwent CMR. Primary outcome measure was aortic distensibility (AD) between controls and ERA, and baseline to year 1 AD change in ERA. Secondary analyses between and within ERA groups performed. Additional outcome measures included left ventricular (LV) mass and myocardial extracellular volume (ECV). RESULTS:Eighty-one patients recruited. In ERA versus controls, respectively, baseline (geometric mean, 95% CI) AD was significantly lower (3.0×10-3 mm Hg-1 (2.7-3.3) vs 4.4×10-3 mm Hg-1 (3.7-5.2), p<0.001); LV mass significantly lower (78.2 g (74.0-82.7), n=81 vs 92.9 g (84.8-101.7), n=30, p<0.01); and ECV increased (27.1% (26.4-27.9), n=78 vs 24.9% (23.8-26.1), n=30, p<0.01). Across all patients, AD improved significantly from baseline to year 1 (3.0×10-3 mm Hg-1 (2.7-3.4) to 3.6×10-3 mm Hg-1 (3.1-4.1), respectively, p<0.01), maintained at year 2. The improvement in AD did not differ between the two treatment arms and disease activity state (Disease Activity Score with 28 joint count)-erythrocyte sedimentation rate-defined responders versus non-responders. CONCLUSION:We report the first evidence of vascular and myocardial abnormalities in an ERA randomised controlled trial cohort and show improvement with DMARD therapy. The type of DMARD (first-line tumour necrosis factor-inhibitors or MTX) and clinical response to therapy did not affect CVD markers.

Project description:IntroductionSome patients with rheumatoid arthritis (RA) using tumor necrosis factor inhibitors (TNFi) experience inefficacy or lack of tolerability and hence switch to another TNFi (cycling) or to a therapy with another mode of action (switching). This study examined patient characteristics, prescribing patterns and treatment practice for RA in the United States.MethodsData were from the Adelphi Disease Specific Programme (Q2-Q3 2016). Rheumatologists completed a survey and patient record forms for adult patients with RA who had received ≥ 1 targeted therapy. Patients were grouped by class of first-used targeted therapy, and monotherapy vs. combination therapy. TNFi patients who received ≥ 1 targeted therapy were classified as cyclers or switchers. Univariate analyses compared patient characteristics and physician factors across the analysis groups.ResultsOverall, 631 patients received ≥ 1 targeted therapy; 535 were prescribed a TNFi as first targeted therapy, 53 a nonTNFi biologic disease-modifying antirheumatic drug (bDMARD), and 43 tofacitinib. Of 577 patients with known conventional synthetic (cs) DMARD status, 18.7% were prescribed monotherapy and 81.3% combination therapy. Combination therapy patients received significantly more concomitant medications prior to initiation of first targeted therapy than monotherapy patients (P < 0.05). The top reason for physicians to prescribe first use targeted therapy was strong overall efficacy (79.9%). Of 163 patients who progressed to second targeted therapy, 60.7% were cyclers. A lower proportion of cyclers persisted on their first use targeted therapy versus switchers (P = 0.03). The main reason physicians gave for switching patients at this stage was worsening condition (46.6%).ConclusionsMost patients were prescribed a TNFi as their first targeted therapy; over half then cycled to another TNFi. This suggests other factors may influence second use targeted treatment choice and highlights the need for greater understanding of outcomes associated with subsequent treatment choices and potential benefits of switching.
