Patient Perspectives on Biologics for Axial Spondyloarthritis in a Cross-sectional Study in a Predominantly Female Population: Treatment Satisfaction, Wear-off Between Doses, and Use of Supplemental Medication.

INTRODUCTION: There is limited information regarding treatment experience of patients with axial spondyloarthritis/ankylosing spondylitis (axSpA/AS) receiving biological disease-modifying antirheumatic drugs (bDMARDs). Here we characterize patient experiences and perspectives, including satisfaction among those currently treated with bDMARD therapy for axSpA/AS. We also assess the use of supplemental medication during perceived wear-off between doses. METHODS: Adult participants from the United States within the ArthritisPower registry with physician-diagnosed axSpA/AS were invited to complete electronic patient-reported outcome measures and an online survey about their perspectives of treatment. Analysis compared patient characteristics and treatment satisfaction by whether wear-off in axSpA/AS between bDMARD doses was reported. RESULTS: Of 128 patients currently taking a DMARD, the mean age was 46.9 (10.3) years, 82.0% were female, and 93.8% were White. A total of 78 (60.9%) perceived wear-off with their current bDMARD before the next dose, 19 (14.8%) did not experience wear-off and 31 (24.2%) were unsure about wear-off. Mean (standard deviation [SD]) Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score indicated poor disease control in all patients receiving bDMARDs (6.4 [1.8]); worse for those perceiving wear-off between doses versus those who did not perceive wear-off or were unsure (6.8 [1.6] vs. 5.9 [2.0], p = 0.011). Patients experiencing wear-off reported being 'very satisfied' or 'somewhat satisfied' with their treatment less frequently than patients without wear-off (73.1 vs. 89.5%, respectively). Of patients reporting wear-off, 82.1% (n = 64) used supplemental medications during wear-off (non-steroidal anti-inflammatory drugs [68.8%, n = 44], muscle relaxants [42.2%, n = 27], and/or opioids [37.5%, n = 24]). CONCLUSIONS: In a predominantly female sample of bDMARD-treated patients with axSpA/AS and high disease activity, the majority expressed treatment satisfaction. However, most experienced wear-off between doses and relied on supplemental medications, including opioids, to manage symptoms.

Treatment Satisfaction and Decision-making from the Patient Perspective in Axial Spondyloarthritis: Real-World Data from a Descriptive Cross-sectional Survey Study from the ArthritisPower Registry.

OBJECTIVE: Aims were to 1) to characterize patient decision-making with treatment for axial spondyloarthritis (axSpA) and 2) to explore relationships among decision-making, treatment satisfaction, and biologic disease modifying antirheumatic drugs (bDMARDs). METHODS: ArthritisPower participants with physician-diagnosed axSpA were invited to complete an online survey about their treatment and their most recent physician visit. Analysis compared treatment decision by satisfaction and bDMARD status. RESULTS: Among the 274 participants, 87.2% were female, and the mean age was 50 years. Of participants, 79.5% had researched treatment before their most recent physician visit, and 56.9% discussed treatment change at their most recent physician visit. Of treatment-change discussions, 69.2% of them were related to escalation, compared with deescalation (27.6%) and/or switching (39.1%). Among those participants who discussed a change, 73.7% agreed to it because they felt that their disease was not being controlled (54.9%) or felt that it could be better controlled on new treatment (20.3%). Top symptoms prompting change were back/buttock pain (63.3%), other joint pain (55.1%), and fatigue (54.1%). Among bDMARD-treated participants (n = 128), important factors for treatment decisions were prevention of long-term axSpA consequences (92.9%) and doctor's advice (87.5%). Among 43.4% of participants reporting treatment dissatisfaction, 37% did not discuss treatment change. Current bDMARD use was more common in satisfied (61.9%) than dissatisfied participants (26.9%). CONCLUSION: In this cross-sectional study of a predominantly female axSpA population, patients frequently researched treatment options and discussed escalation with their providers. Under two-thirds of participants who were dissatisfied with treatment discussed changes at their most recent visit. Current bDMARD use was associated with higher satisfaction, and bDMARD users considered prevention of long-term consequences and doctor's advice to be very important for decision-making.

Neurologic drug-psychotropic drug update.

It is essential that both the neurologist and the psychiatrist be aware of the neurology drug-psychotropic drug interactions because neurologists prescribe many psychotropic medications and psychiatric consultants often recommend the use of psychotropic drugs for neurology patients. Six methods of examining drug-drug interactions were employed: 1) PubMed (MEDLINE); 2) Hanston's Drug Interaction Analysis and Management Text (July 2001 quarterly updated version); 3)Drug Interactions Facts (quarterly updated version through July 2001); 4) Micromedex Drug-dex; 5) American Hospital Formulary Service Drug Information; 6) Food and Drug Administration (MedWatch) Dear Doctor Letters and new labeling. Over eighty important interactions of significance level 1 (major), or significance level 2 (minor) were found. Furthermore, over one-third of the neurologist's most commonly administered medications were those also employed by the psychiatrist, but not necessarily for the same reason, e.g., carbamazepine, for seizure control (neurologist) or mood stabilization (psychiatrist).
