Effect of Dysmetabolisms and Comorbidities on the Efficacy and Safety of Biological Therapy in Chronic Inflammatory Joint Diseases

Real-World Data from a Multi-Center Study: Insights to Psoriatic Arthritis Care

Introduction: Real-world data indicate disparities in biologic access across Europe. Objectives: To describe the national structure of PsA care in Poland, with a particular focus on the population of inadequate responders (IRs) and difficulties associated with biologic therapy access. Methods: A pool of rheumatologic and dermatologic care centers was created based on National Health Fund contract lists (n = 841), from which 29 rheumatologic and 10 dermatologic centers were sampled randomly and successfully met the inclusion criterium. Additionally, 33 tertiary care centers were recruited. For successful center recruitment, one provider had to recruit at least one patient that met the criteria for one of the four pre-defined clinical subgroups, in which all patients had to have active PsA and IR status to at least 2 conventional synthetic disease-modifying drugs (csDMARDs). Self-assessment questionnaires were distributed among physicians and their patients. Results: Barriers to biologic DMARD (bDMARD) treatment are complex and include stringency of reimbursement criteria, health care system, logistic/organizational, and personal choice factors. For patients who are currently bDMARD users, the median waiting time from the visit, at which the reimbursement procedure was initiated, to the first day of bDMARD admission was 9 weeks (range 2–212; 32% < 4 weeks, 29% 5–12 weeks, 26% 13–28 weeks, 13% with >28 weeks delay). Out of all inadequate responder groups, bDMARD users are the only group with “good” therapeutic situation and satisfaction with therapy. Patient satisfaction with therapy is not always concordant with physician assessment of therapeutic status. Conclusions: Despite the fact that over a decade has passed since the introduction of biologic agents, in medium welfare countries such as Poland, considerable healthcare system barriers to biologic access are present. Out of different IR populations, patient satisfaction with treatment is often discordant with physician assessment of disease status.

Risk factors for hypertension in rheumatoid arthritis patients-A systematic review

INTRODUCTION

Rheumatoid arthritis is frequently associated with hypertension, which has been shown to increase the risk of cardiovascular disease in these patients. The aim of this systematic review was to explore demographic, behavioural or clinical factors including medication use, associated with incident hypertension in rheumatoid arthritis.

METHODS

MEDLINE and Scopus were searched for eligible studies that longitudinally investigated incident hypertension or changes in blood pressure (BP) in rheumatoid arthritis patients. Publications were screened by two reviewers according to predetermined inclusion and exclusion criteria. The quality of included studies was assessed via the Newcastle Ottawa Scale and Cochrane Risk of Bias Tool.

RESULTS

Fourteen studies were deemed eligible and included in this review. The proportion of female subjects ranged from 12 to 87% and the mean age ranged from 47 to 61 years. Regular exercise was associated with a decrease in systolic BP, p = 0.021. Methotrexate was associated with decreased risk of hypertension in two studies. LEF was associated with increased BP in two studies. COX-2 inhibitors were associated with systolic BP and diastolic BP variability (p = 0.009, 0.039, respectively) in one study. Prednisone was found to increase BP and risk of hypertension in three studies. The risk of hypertension in patients taking biologic disease modifying anti-rheumatic drugs (DMARDs) is unclear as some studies report increased BP while others report no difference for biologic compared to conventional DMARDs.

CONCLUSION

Despite limited longitudinal studies exploring this topic, methotrexate and exercise were shown to protect against risk of hypertension in RA patients, while prednisone and COX-2 inhibitors may increase risk of hypertension.
