The role of patient adherence in improving the efficacy of any treatment is widely accepted, as well as its impact in optimizing the use of healthcare resources and associated costs. Adherence is particularly affected in chronic conditions, such as rheumatoid arthritis (RA), requiring long-term therapies and a commitment of the patient to manage his/her disease. Methotrexate (MTX) is one of the mainstays of treatment for several immune-mediated inflammatory joint and skin diseases, especially RA. The use of parenteral MTX, particularly when administered as a subcutaneous (SC) injection, has recently raised a great interest to overcome the limitations of oral MTX. For addressing this issue, new optimized self-injection systems have been developed to improve the ease of use of SC MTX. Increasing evidence shows how patients tend to opt for autoinjectors over prefilled syringes or conventional syringes in terms of easiness of use, preference and satisfaction, regardless of whether the treatment is a biologic or MTX. Additionally, positive views and beliefs of patients about treatment may contribute to increasing expectations of effectiveness and treatment adherence. Similarly, the implementation of prefilled pens in clinical practice might be a way to facilitate and simplify the self-injection of SC MTX delivery, optimizing adherence and treatment outcomes as a consequence. This article aimed to review the available literature data on the use of MTX autoinjectors and their impact on treatment adherence and patients’ perceptions.

Background Triple antithrombotic therapy (TT) is recommended for patients with nonvalvular atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). However, there is a lack of comparative data in a real-world clinical setting between non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA). The aim of this study was to compare the safety and efficacy of TT with NOAC or VKA after PCI in patients with AF at 1-year of follow-up. Materials and Methods This was an observational retrospective study in 2 tertiary care hospitals during 2013-2016. Patients with indication for anticoagulation due to AF from an initial registry of 5,269 patients undergoing PCI were identified. Safety primary endpoint was the occurrence of major bleeding events as defined by Bleeding Academic Consortium (BARC ≥ 3). The primary efficacy endpoint was defined as major adverse cardiovascular events (MACE). Results A total of 187 consecutive patients on TT were identified: 45.4% of were discharged on NOAC and 54.6% on VKA. Patients who received VKA presented more comorbidities and had a higher bleeding risk than those who received NOACs. Major bleeding events occurred in 17 patients (9%), with a higher rate in the VKA group (3.5% vs. 13% confidence interval, 0.19-0.86, P = 0.02). There were no differences in the rates of major adverse cardiovascular events, stroke or net clinical benefit. Conclusions In this real-world study, patients with AF undergoing PCI treated on NOAC-based TT showed lower bleeding rates than those on VKA, with a lower rate of major bleeding events, while efficacy was similar between groups.

Background Limited data exists on the impact of sex on outcomes in non-valvular atrial fibrillation (NVAF) patients undergoing percutaneous coronary intervention (PCI). We explored the impact of sex on ischemic and bleeding events in these patients within 1-year. Methods A prospective register included 1021 patients with NVAF undergoing PCI and 253 (24.8%) were women. The primary end point was a composite of cardiovascular death, stroke or systemic embolism (SSE). The secondary end-point was major bleeding events defined as a Bleeding Academic Research Consortium (BARC ≥ 3a). Results Women were older (76.8 ± 7.7 vs 71.8 ± 9.1 years, p Conclusions Female with NVAF undergoing PCI showed a lower TTR than men and TTR was associated with bleeding events. Female sex was an independent risk factor for cardiovascular death and major bleeding.
