Risk of Biologics and Glucocorticoids in Patients With Rheumatoid Arthritis Undergoing Arthroplasty: A Cohort Study.

ABSTRACT:

Background

Patients with rheumatoid arthritis (RA) are at increased risk for infection after arthroplasty, yet risks of specific biologic medications are unknown.

Objective

To compare risk for postoperative infection among biologics and to evaluate the risk associated with glucocorticoids.

Design

Retrospective cohort study.

Setting

Medicare and Truven MarketScan administrative data from January 2006 through September 2015.

Patients

Adults with RA who were having elective inpatient total knee or hip arthroplasty, either primary or revision, and had a recent infusion of or prescription for abatacept, adalimumab, etanercept, infliximab, rituximab, or tocilizumab before surgery.

Measurements

Propensity-adjusted analyses using inverse probability weights evaluated comparative risks for hospitalized infection within 30 days and prosthetic joint infection (PJI) within 1 year after surgery between biologics or with different dosages of glucocorticoids. Secondary analyses evaluated non-urinary tract hospitalized infections and 30-day readmissions.

Results

Among 9911 patients treated with biologics, 10 923 surgical procedures were identified. Outcomes were similar in patients who received different biologics. Compared with an 8.16% risk for hospitalized infection with abatacept, predicted risk from propensity-weighted models ranged from 6.87% (95% CI, 5.30% to 8.90%) with adalimumab to 8.90% (CI, 5.70% to 13.52%) with rituximab. Compared with a 2.14% 1-year cumulative incidence of PJI with abatacept, predicted incidence ranged from 0.35% (CI, 0.11% to 1.12%) with rituximab to 3.67% (CI, 1.69% to 7.88%) with tocilizumab. Glucocorticoids were associated with a dose-dependent increase in postoperative risk for all outcomes. Propensity-weighted models showed that use of more than 10 mg of glucocorticoids per day (vs. no glucocorticoid use) resulted in a predicted risk for hospitalized infection of 13.25% (CI, 9.72% to 17.81%) (vs. 6.78%) and a predicted 1-year cumulative incidence of PJI of 3.83% (CI, 2.13% to 6.87%) (vs. 2.09%).

Limitation

Residual confounding is possible, and sample sizes for rituximab and tocilizumab were small.

Conclusion

Risks for hospitalized infection, PJI, and readmission after arthroplasty were similar across biologics. In contrast, glucocorticoid use, especially with dosages above 10 mg/d, was associated with greater risk for adverse outcomes.

Project description:BackgroundLow-dose glucocorticoids are frequently used for the management of rheumatoid arthritis (RA) and other chronic conditions, but the safety of long-term use remains uncertain.ObjectiveTo quantify the risk for hospitalized infection with long-term use of low-dose glucocorticoids in patients with RA receiving stable disease-modifying antirheumatic drug (DMARD) therapy.DesignRetrospective cohort study.SettingMedicare claims data and Optum's deidentified Clinformatics Data Mart database from 2006 to 2015.PatientsAdults with RA receiving a stable DMARD regimen for more than 6 months.MeasurementsAssociations between glucocorticoid dose (none, ≤5 mg/d, >5 to 10 mg/d, and >10 mg/d) and hospitalized infection were evaluated using inverse probability-weighted analyses, with 1-year cumulative incidence predicted from weighted models.Results247 297 observations were identified among 172 041 patients in Medicare and 58 279 observations among 44 118 patients in Optum. After 6 months of stable DMARD use, 47.1% of Medicare patients and 39.5% of Optum patients were receiving glucocorticoids. The 1-year cumulative incidence of hospitalized infection in Medicare patients not receiving glucocorticoids was 8.6% versus 11.0% (95% CI, 10.6% to 11.5%) for glucocorticoid dose of 5 mg or less per day, 14.4% (CI, 13.8% to 15.1%) for greater than 5 to 10 mg/d, and 17.7% (CI, 16.5% to 19.1%) for greater than 10 mg/d (all P < 0.001 vs. no glucocorticoids). The 1-year cumulative incidence of hospitalized infection in Optum patients not receiving glucocorticoids was 4.0% versus 5.2% (CI, 4.7% to 5.8%) for glucocorticoid dose of 5 mg or less per day, 8.1% (CI, 7.0% to 9.3%) for greater than 5 to 10 mg/d, and 10.6% (CI, 8.5% to 13.2%) for greater than 10 mg/d (all P < 0.001 vs. no glucocorticoids).LimitationPotential for residual confounding and misclassification of glucocorticoid dose.ConclusionIn patients with RA receiving stable DMARD therapy, glucocorticoids were associated with a dose-dependent increase in the risk for serious infection, with small but significant risks even at doses of 5 mg or less per day. Clinicians should balance the benefits of low-dose glucocorticoids with this potential risk.Primary funding sourceNational Institute of Arthritis and Musculoskeletal and Skin Diseases.

Project description:BackgroundThis multi-center, retrospective study aimed to clarify retention rates and reasons for discontinuation of 7 biological disease-modifying antirheumatic drugs (bDMARDs) and tofacitinib (TOF), one of the janus kinase inhibitors, in bDMARDs-naïve and bDMARDs-switched patients with rheumatoid arthritis (RA).MethodsThis study assessed 3897 patients and 4415 treatment courses with bDMARDs and TOF from 2001 to 2019 (2737 bDMARDs-naïve courses and 1678 bDMARDs-switched courses [59.5% of switched courses were their second agent], female 82.3%, baseline age 57.4 years, disease duration 8.5 years; rheumatoid factor positivity 78.4%; Disease Activity Score in 28 joints using erythrocyte sedimentation rate 4.3; concomitant prednisolone [PSL] dose 6.1 mg/day [usage 42.4%], and methotrexate [MTX] dose 8.5 mg/week [usage 60.9%]). Treatment courses included abatacept (ABT; n = 663), adalimumab (ADA; n = 536), certolizumab pegol (CZP; n = 226), etanercept (ETN; n = 856), golimumab (GLM; n = 458), infliximab (IFX; n = 724), tocilizumab (TCZ; n = 851), and TOF (n = 101/only bDMARDs-switched cases). Drug discontinuation reasons (categorized into lack of effectiveness, toxic adverse events, non-toxic reasons, or remission) and rates were estimated at 36 months using Gray's test and statistically evaluated after adjusted by potential clinical confounders (age, sex, disease duration, concomitant PSL and MTX usage, starting date, and number of switched bDMARDs) using the Fine-Gray model.ResultsCumulative incidence of drug discontinuation for each reason was as follows: lack of effectiveness in the bDMARDs-naïve group (from 13.7% [ABT] to 26.9% [CZP]; P < 0.001 between agents) and the bDMARDs-switched group (from 18.9% [TCZ] to 46.1% [CZP]; P < 0.001 between agents); toxic adverse events in the bDMARDs-naïve group (from 4.6% [ABT] to 11.2% [ETN]; P < 0.001 between agents) and the bDMARDs-switched group (from 5.0% [ETN] to 15.7% [TOF]; P = 0.004 between agents); and remission in the bDMARDs-naïve group (from 2.9% [ETN] to 10.0% [IFX]; P < 0.001 between agents) and the bDMARDs-switched group (from 1.1% [CZP] to 3.3% [GLM]; P = 0.9 between agents).ConclusionsRemarkable differences were observed in drug retention of 7 bDMARDs and TOF between bDMARDs-naïve and bDMARDs-switched cases.

Project description:ObjectivesObesity is associated with lower treatment response in patients with rheumatoid arthritis (RA). In patients with obesity, abatacept was suggested as a preferable option to tumour necrosis factor-alpha inhibitors. We aimed to assess the comparative effectiveness of etanercept, infliximab and abatacept, compared with adalimumab, in patients with RA with obesity. Secondarily, we also investigated this in patients with overweight and normal weight for completeness.DesignObservational cohort study.SettingSwiss Clinical Quality Management in Rheumatic Diseases (SCQM) registry (1997-2019).ParticipantsAdult patients with RA from the SCQM registry who received etanercept, infliximab, abatacept or adalimumab as their first biological or targeted synthetic disease-modifying antirheumatic drug were classified based on their body mass index (BMI) at the start of that treatment in three cohorts: obese, overweight, normal weight. They were followed for a maximum of 1 year.ExposureThe study exposure of interest was the patients' first biological, particularly: etanercept, infliximab and abatacept, compared with adalimumab.Primary and secondary outcome measuresThe primary study outcome was remission within 12 months, defined as 28-joint Disease Activity Score (DAS28) <2.6. Missingness was addressed using confounder-adjusted response rate with attrition correction. Logistic regression was used to compare the effectiveness of etanercept, infliximab and abatacept versus adalimumab. Each BMI cohort was addressed and analysed separately.ResultsThe study included 443 obese, 829 overweight and 1243 normal weight patients with RA. There were no statistically significant differences in the odds of DAS28-remission at ≤12 months for etanercept, infliximab and abatacept, compared with adalimumab, in any of the BMI cohorts.ConclusionsNo differences in DAS28-remission were found between the study drugs and adalimumab as first biologic in patients with RA, independently of the BMI cohort. We did not find evidence that treatment with abatacept increased the likelihood of remission compared with adalimumab among obese patients with RA.
