Comparative Cardiovascular Risk of Abatacept and Tumor Necrosis Factor Inhibitors in Patients With Rheumatoid Arthritis With and Without Diabetes Mellitus: A Multidatabase Cohort Study

Background: We examined the cardiovascular risk of abatacept compared with tumor necrosis factor (TNF) inhibitors in patients with rheumatoid arthritis with and without diabetes mellitus (DM). Methods and Results: We conducted a cohort study of patients with rheumatoid arthritis who newly started abatacept or TNF inhibitors using claims data from Medicare and MarketScan. The primary outcome was a composite cardiovascular end point of myocardial infarction (MI), stroke/transient ischemic attack, and coronary revascularization. To account for >60 baseline characteristics, abatacept initiators were 1:1 propensity score (PS) matched to TNF initiators in each database. Cox proportional hazards models estimated hazard ratio (HR) and 95% confidence interval (CI) in the PS‐matched cohort per database. A fixed‐effects meta‐analysis pooled database‐specific HRs. We included a total of 13 039 PS‐matched pairs of abatacept and TNF inhibitor initiators (6103 pairs in Medicare and 6936 pairs in MarketScan). A total of 34.7% in Medicare and 19.8% in MarketScan had baseline DM. The HR (95% CI) for the primary outcome associated with abatacept use versus TNF inhibitor was 0.81 (0.66–0.99) in Medicare and 0.95 (0.74–1.23) in MarketScan, with a pooled HR of 0.86 (95% CI, 0.73–1.01; P=0.3 for heterogeneity). The risk of the primary outcome was lower in abatacept initiators versus TNF inhibitors in the DM subgroup, with a pooled HR of 0.74 (95% CI, 0.57–0.96; P=0.7 for heterogeneity), but not in the non‐DM subgroup, with a pooled HR of 0.94 (95% CI, 0.77–1.14; P=0.4 for heterogeneity). Conclusions: In this large population‐based cohort of patients with rheumatoid arthritis, abatacept use appeared to be associated with a modestly reduced cardiovascular risk when compared with TNF inhibitor use, particularly in patients with DM

Medication Adherence and Healthcare Disparities: Impact of Statin Co-Payment Reduction

Objectives: Minority patients have lower rates of cardiovascularmedication adherence, which may be amenable to co-payment reductions.Our objective was to evaluate the effect of race on adherencechanges following a statin co-payment reduction intervention.Study Design: Retrospective analysis.Methods: The intervention was implemented by a large selfinsuredemployer. Eligible individuals in the intervention cohort(n = 1961) were compared with a control group of employees ofother companies without such a policy (n = 37,320). As a proxy forrace, we categorized patients into tertiles based on the proportionof black residents living in their zip code of residence. Analyseswere performed using difference-in-differences design with generalizedestimating equations.Results: Prior to the new co-payment policy, adherence rateswere higher for individuals living in areas with fewer black residents.In multivariable models adjusting for demographic factors,clinical covariates and baseline trends, the co-payment reductionincreased adherence by 2.0% (P = .14), 2.1% (P = .15) and 6% (PStatistic

Soluble Flt1 levels are associated with cardiac dysfunction in Black women with and without severe preeclampsia

Background: We evaluate soluble fms-like tyrosine kinase-1 (sFlt-1) levels and cardiac function during pregnancy and postpartum among Black women with and without preeclampsia. Study design: Prospective longitudinal cohort study from 2015 to 2017 of Black women with preterm severe preeclampsia and normotensive pregnant controls.We obtained echocardiograms and sFlt-1 levels during pregnancy and postpartum. Results: 93 Black women were included (43 cases, 50 controls). Higher sFlt1 levels were correlated with worse longitudinal strain, diastolic dysfunction, decreased ventricular-arterial coupling, and increased chamber and arterial elastance at the time of preeclampsia diagnosis and postpartum. Conclusions: Higher sFlt1 levels are associated with cardiovascular dysfunction during pregnancy and postpartum

Trends, Predictors, and Outcomes of Cardiovascular Complications at Delivery Associated With Gestational Diabetes: A National Inpatient Sample Analysis (2004-2019)

Background: Gestational diabetes (GD) is associated with increased risk of long-term cardiovascular complications. However, data on acute peripartum cardiovascular complications are not well established. Hence, we aimed to investigate the association of GD with acute cardiovascular outcomes at the time of delivery admission. Methods and Results: We used data from the National Inpatient Sample (2004-2019). International Classification of Diseases, Ninth Revision (ICD-9) or Tenth Revision (ICD-10) codes were used to identify delivery hospitalizations and GD diagnosis. A total of 63 115 002 weighted hospitalizations for deliveries were identified, of which 3.9% were among individuals with GD (n=2 435 301). The prevalence of both GD and obesity increased during the study period (P trends\u3c 0.01). Individuals with GD versus those without GD had a higher prevalence of obesity, hypertension, and dyslipidemia. After adjustment for age, race or ethnicity, comorbidities, insurance, and income, GD remained independently associated with cardiovascular complications including preeclampsia (adjusted odds ratio [aOR], 1.97 [95% CI, 1.96-1.98]), peripartum cardiomyopathy (aOR, 1.15 [1.08-1.22]), acute kidney injury (aOR, 1.16 [1.11-1.21]), stroke (aOR, 1.15 [1.09-1.23]), and arrhythmias (aOR, 1.48 [1.46-1.50]), compared with no GD. Moreover, delivery hospitalizations among individuals with GD were associated with increased length (3 versus 2 days, P\u3c 0.01) and cost of hospitalization ($4909 versus$3682, P\u3c 0.01). Even in the absence of preeclampsia, GD was associated with elevated cardiovascular risk. Conclusions: Individuals with GD had a higher risk of preeclampsia, peripartum cardiomyopathy, acute kidney injury, stroke, and arrhythmias during delivery hospitalizations. As rates of GD are increasing globally, efforts to improve preconception cardiometabolic health and prevent GD may represent important strategies to improve peripartum maternal outcomes and mitigate long-term cardiovascular risk

Targeted Adherence Intervention to Reach Glycemic Control with Insulin Therapy for patients with Diabetes (TARGIT-Diabetes): rationale and design of a pragmatic randomised clinical trial

Introduction: Adherence to and persistence of medications for chronic diseases remains poor and many interventions to improve medication use have only been modestly effective. Targeting interventions to patients who are most likely to benefit should improve their efficiency and clinical impact. This study aims to test the impact of three cost-equivalent pharmacist-led interventions on insulin persistence and glycaemic control among patients with diabetes. Methods and analysis TARGIT-Diabetes (Targeted Adherence Intervention to Reach Glycemic Control with Insulin Therapy for patients with Diabetes) is a randomised controlled trial that will evaluate three different multifaceted pharmacist-outreach strategies for improving long-term insulin use among individuals with diabetes. We will randomise 6000 patients in a large insurer to one of three arms. The arms are designed to deliver an increasingly intensive intervention to a progressively targeted population, identified using predictive analytics. The central component of the intervention in all arms is a tailored telephone consultation with a pharmacist which varies across arms based on the: (A) proportion of patients offered the intervention and (B) intervention intensity, including follow-up frequency and cointerventions such as text reminders and interactions with patients’ providers. The primary outcome is insulin persistence, assessed using pharmacy claims data, and the secondary outcomes are glycaemic control as measured by glycosylated haemoglobin values, healthcare utilisation and healthcare spending. Ethics and dissemination This protocol has been approved by the Institutional Review Board of Brigham and Women’s Hospital and the Privacy Board of Horizon Blue Cross Blue Shield of New Jersey. We plan to present the results of this trial at national meetings and in manuscripts submitted to peer-reviewed journals. Trial registration number NCT 02846779
