Perspectives of Patients with Multiple Sclerosis on Drug Treatment: A Qualitative Study

Anticipated Stigma among Patients with Multiple Sclerosis in Saudi Arabia

Background

Social stigma is a major problem among patients with multiple sclerosis (MS), which can affect their quality of life. There is limited research from Saudi Arabia on the anticipated stigma among patients with MS.

Objectives

To determine the levels of anticipated stigma and its predictors in patients with MS in Saudi Arabia.

Methods

This cross-sectional study included adult patients with MS across Saudi Arabia. Sociodemographic and medical information, including age, gender, marital status, educational level, duration of disease, number of MS episodes in the past 12 months, previous diagnosis of mental illness, and performing activities of daily living without assistance, were collected. Anticipated stigma was measured using an Arabic version of the Chronic Illness Anticipated Stigma Scale.

Results

A total of 222 patients with MS were included. Moderate to severe anticipated stigma was found among 70.4% of the patients. The highest anticipated stigma mean score was from work colleagues (2.96/5). Predictors of stigma were age (P = 0.049), gender (P = 0.016), marital status (P = 0.015), education level (P = 0.003), number of MS episodes in the previous year (P < 0.001), and previous diagnosis of a mental disorder (P = 0.001).

Conclusions

The findings of this study indicate the need for developing programs that reduce the anticipated stigma among patients with MS in Saudi Arabia.

Medication self-management toolkits for adults with multiple sclerosis: A scoping review

Background

Multiple sclerosis (MS) is an autoimmune disease that is often treated with multiple medications. Managing multiple medications, also known as polypharmacy, can be challenging for persons with MS. Toolkits are instructional resources designed to promote behaviour change. Toolkits may support medication self-management for adults with MS, as they have been useful in other populations with chronic conditions.

Objective

The main purpose of this review was to identify and summarize medication self-management toolkits for MS, as related to the design, delivery, components, and measures used to evaluate implementation and/or outcomes.

Methods

A scoping review was conducted following guidelines by JBI. Articles were included if they focused on adults (18 years or older) with MS.

Results

Six articles reporting on four unique toolkits were included. Most toolkits were technology-based, including mobile or online applications, with only one toolkit being paper-based. The toolkits varied in type, frequency, and duration of medication management support. Varying outcomes were also identified, but there were improvements reported in symptom management, medication adherence, decision-making, and quality of life. The six studies were quantitative in design, with no studies exploring the user experience from a qualitative or mixed-methods design.

Conclusions

There is limited research on medication self-management toolkits among adults with MS. Future development, implementation, and evaluation mixed-methods research are needed to explore user experiences and overall design of toolkits.

Exploring Biologic Treatment Hesitancy Among Black and Indigenous Populations in Canada: a Review

Biologics are becoming an increasingly important part of patient care across Canada. Recent studies from the USA show that Black patients are less likely than White patients to receive biologic treatment for several medical conditions. The relative lack of race-based data in Canada makes it difficult to replicate such studies in Canada. As a result, there is a paucity of literature that explores the association between biologic usage and race in Canada. Our review aims to explore the factors that might be driving racial treatment disparity in Canada that likely parallels the inequalities found in the USA. We provide a summary of the available literature on the factors that contribute to biologic treatment hesitancy among Black and Indigenous populations in Canada. We highlight several solutions that have been proposed in the literature to address biologic treatment hesitancy. Our review found that biologic treatment decision at the individual level can be very complex as patient's decisions are influenced by social inputs from family and trusted community members, biologic-related factors (negative injection experience, fear of needles, formulation, and unfamiliarity), cultural tenets (beliefs, values, perception of illness), and historical and systemic factors (past research injustices, socioeconomic status, patient-physician relationship, clinical trial representation). Some proposed solutions to address biologic treatment hesitancy among Black and Indigenous populations include increasing the number of Black and Indigenous researchers involved in and leading clinical trials, formally training physicians and healthcare workers to deliver culturally competent care, and eliminating financial barriers to accessing medications. Further research is needed to characterize and address race-based new treatment inequalities and hesitancy in Canada.

Diroximel Fumarate as a Novel Oral Immunomodulating Therapy for Relapsing Forms of Multiple Sclerosis: A Review on the Emerging Data

Multiple sclerosis (MS) is a chronic inflammatory, demyelinating and neurodegenerative disorder of the central nervous system. Disease-modifying drugs (DMDs) and subsequent adherence are crucial for preventing reversible episodes of neurological dysfunction and delayed onset of progressive accumulation of irreversible deficits. Yet, side effects may limit their usage in clinical practice. Gastrointestinal (GI) side effects are a significant limitation of the use of dimethyl fumarate (DMF), the most frequently prescribed oral DMD in MS worldwide. Diroximel fumarate (DRF) is a second-generation oral fumaric acid ester (FAE) that was developed as a formulation with better GI tolerability. The improved tolerability is assumed to be related to a lower synthesis of gut-irritating methanol. Other explanations for DRF’s lower extent of GI irritation include a more modest off-target activity due to its chemical structure. The superior GI tolerability of DRF compared to DMF could be proven in clinical trials and lead to approval of DRF for the treatment of relapsing forms of MS/relapsing-remitting MS (United States Food and Drug Administration and European Medicines Agency, respectively). Here, we summarize the mode of action of oral FAE and compare the chemical and physiological characteristics of DMF and DRF. Moreover, we discuss the adverse effects of FAE and introduce the emerging preclinical and trial data leading to the approval of DRF in MS. This article additionally reviews our current understanding of coronavirus disease 2019 (COVID-19) and the efficacy of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccination in people treated with FAE.

Patient-based benefit-risk assessment of medicines: development, refinement, and validation of a content search strategy to retrieve relevant studies

Introduction:

Poor indexing and inconsistent use of terms and keywords may prevent efficient retrieval of studies on the patient-based benefit-risk assessment (BRA) of medicines. We aimed to develop and validate an objectively derived content search strategy containing generic search terms that can be adapted for any search for evidence on patient-based BRA of medicines for any therapeutic area.

Methods:

We used a robust multistep process to develop and validate the content search strategy: (1) we developed a bank of search terms derived from screening studies on patient-based BRA of medicines in various therapeutic areas, (2) we refined the proposed content search strategy through an iterative process of testing sensitivity and precision of search terms, and (3) we validated the final search strategy in PubMed by firstly using multiple sclerosis as a case condition and secondly computing its relative performance versus a published systematic review on patient-based BRA of medicines in rheumatoid arthritis.

Results:

We conceptualized a final search strategy to retrieve studies on patient-based BRA containing generic search terms grouped into two domains, namely the patient and the BRA of medicines (sensitivity 84%, specificity 99.4%, precision 20.7%). The relative performance of the content search strategy was 85.7% compared with a search from a published systematic review of patient preferences in the treatment of rheumatoid arthritis. We also developed a more extended filter, with a relative performance of 93.3% when compared with a search from a published systematic review of patient preferences in lung cancer.

Feel to Heal: Negative Emotion Differentiation Promotes Medication Adherence in Multiple Sclerosis

Multiple Sclerosis (MS) is a debilitating chronic autoimmune disease of the central nervous system that results in lower quality of life. Medication adherence is important for reducing relapse, disease progression, and MS-related symptoms, particularly during the early stages of MS. However, adherence may be impacted by negative emotional states. Therefore, it is important to identify protective factors. Past research suggests that the ability to discriminate between negative emotional states, also known as negative emotion differentiation (NED), may be protective against enactment of maladaptive risk-related behaviors. However, less is known as to how NED may promote adaptive health behaviors such as medication adherence. Utilizing weekly diaries, we investigated whether NED moderates the association between negative affect and medication adherence rates across 58 weeks among patients (n = 27) newly diagnosed with MS (following McDonald criteria). Results revealed that NED significantly moderated the relationship between negative affect and medication adherence. Specifically, greater negative affect was associated with lower adherence only for individuals reporting low NED. However, this link disappeared for those reporting moderate to high NED. Building upon past research, our findings suggest that NED may promote adaptive health behaviors and have important clinical implications for the treatment and management of chronic illness.

An implantable device to treat multiple sclerosis: A discrete choice experiment on patient preferences in three European countries

BACKGROUND

Persons with multiple sclerosis (MS) take their treatment via pills, injections or infusions. A novel mode of disease-modifying treatment administration, an implantable device, is under development. This study determined MS patient preferences for three modes of first-line treatment administration (implant, pills, injectables), and trade-offs regarding treatment characteristics.

METHODS

A survey including a discrete choice experiment was conducted among MS patients in the Netherlands, France, and the United Kingdom. Respondents had to repeatedly choose between various treatment scenarios with four treatment characteristics: risk of relapse, reduction of disease progression, risk of side effects and mode of administration. Data was analysed using a panel latent class logit model.

RESULTS

Based on the preferences of 753 MS patients (response rate 7%: 753/11202), two latent classes were identified (class probability of 74% vs 26%). Persons with relapsing-remitting MS and who administered medication via injections generally preferred any treatment over no treatment. Patients who could walk without an aid were more likely to prefer no treatment. Reducing disease progression was the most important treatment characteristic class 1. Mode of administration was the most important characteristic in class 2. Patients were willing to accept an increase in risk of relapse and disease progression to get their treatment via an implant rather than injections. Predicted uptake was the highest for the implant, followed by pills, injections, and no treatment.

CONCLUSION

We found that a drug-delivery implant could be a potential addition to the MS treatment landscape: MS patients are willing to trade-off risk of relapse and disease progression for an implant, and predicted uptake for an implant is relatively high.

Improved gastrointestinal profile with diroximel fumarate is associated with a positive impact on quality of life compared with dimethyl fumarate: results from the randomized, double-blind, phase III EVOLVE-MS-2 study

Background:

Diroximel fumarate (DRF) is a novel oral fumarate approved for relapsing forms of multiple sclerosis (MS). DRF demonstrated significantly improved gastrointestinal (GI) tolerability versus dimethyl fumarate (DMF) with fewer days of Individual Gastrointestinal Symptom and Impact Scale (IGISIS) scores ⩾2, GI adverse events (AEs), and treatment discontinuations due to GI AEs. Our aim was to evaluate the impact of GI tolerability events on quality of life (QoL) for patients with relapsing–remitting MS who received DRF or DMF in EVOLVE-MS-2.

Methods:

A post hoc analysis was conducted in patients who were enrolled in the randomized, blinded, 5-week, EVOLVE-MS-2 [ClinicalTrials.gov identifier: NCT03093324] study of DRF versus DMF. Patients completed daily IGISIS and Global GISIS (GGISIS) eDiary questionnaires to assess GI symptom intensity and interference with daily activities and work.

Results:

In total, 504 patients (DRF, n = 253; DMF, n = 251) received study drug and 502 (DRF, n = 253; DMF, n = 249) completed at least one post-baseline questionnaire. With DRF, GI symptoms were less likely to interfere ‘quite a bit’ or ‘extremely’ with regular daily activities [IGISIS: DRF, 9.5% (24/253) versus DMF, 28.9% (72/249)] or work productivity [GGISIS: DRF, 6.1% (10/165) versus DMF, 11.3% (18/159)]. DRF-treated patients had fewer days with ⩾1 h of missed work (DRF, 43 days, n = 20 versus DMF, 88 days, n = 26). DMF-treated patients reported highest GI symptom severity and missed work at week 2–3 shortly after completing the titration period, which coincided with the majority of GI-related treatment discontinuations [58.3% (7/12)]. GI tolerability AEs [DRF, 34.8% (88/253); DMF, 48.2% (121/251)], concomitant symptomatic medication use [DRF, 19.3% (17/88) versus DMF, 30.6% (37/121)], and GI-related discontinuations (DRF, 0.8% versus DMF, 4.8%) were lower with DRF versus DMF.

Conclusions:

The improved GI tolerability with DRF translated into clinically meaningful benefits to QoL, as patients experienced less impact on daily life and work and required less concomitant symptomatic medication use.

Innovative Medical Technology and the Treatment Decision-Making Process in Multiple Sclerosis: A Focus Group Study to Examine Patient Perspectives

BACKGROUND

Disease-modifying therapies are given to people with multiple sclerosis (MS) to reduce disease progression and relapse frequency. Current modes of administration include oral, injectable and infusion therapy and the treatment decision-making process is complex. A novel mode of treatment administration, an implantable device, is currently under development, yet patient attitudes about the device are unknown. The aim of this study was 1) to understand the treatment decision-making process from the patient perspective and 2) to explore the possible acceptance of an implant to treat MS.

METHODS

Focus groups with people with MS were conducted in the Netherlands. Three topics were addressed: the treatment decision-making process, the current treatment landscape, and attitudes about the implantable device. All focus groups were recorded and transcribed and data were analyzed by raw data coding and creating themes. An online survey was conducted in the Netherlands to quantify interest in an implant.

RESULTS

Two focus group sessions were held (n=16 participants) and n=93 persons filled out the survey. The main theme that emerged was the constant uncertainty persons with MS face throughout their disease course and during treatment decisions (when to start, stop, continue or switch treatment). Patients were generally positive towards the implant but felt that efficacy and safety should be guaranteed.

CONCLUSION

People with MS want some form of control over their disease and treatment course. New medical technologies, such as an implant, may enhance the treatment landscape and with caution we postulate that it may be accepted by patients as a new mode of administration, though further research is needed. For medical technologies to be successful, patients should be engaged early on in the design process.

Patient perspective on decisions to switch disease-modifying treatments in relapsing-remitting multiple sclerosis

BACKGROUND

There are now large cohorts of people with relapsing-remitting multiple sclerosis (pwRRMS) who have taken several Disease-Modifying Treatments (DMTs). Studies about switching DMTs mostly focus on clinical outcomes rather than patients' decision-making. Neurologists are now required to support decisions at various times during the relapsing disease course and they do so with concerns about DMTs risks. This qualitative study investigates how pwRRMS weigh up the pros and cons of DMTs, focusing on perceptions of effectiveness and risks when new treatments are considered.

OBJECTIVE

To increase understanding of people's experiences of decision-making when switching DMTs.

METHODS

30 semi-structured interviews were conducted with pwRRMS in England. 16 participants had switched DMT and their experiences were compared with those who had only taken one DMT. Interviews were analysed thematically to answer: what main factors influence people's decision-making to switch DMTs and why?

RESULTS

Of the 16 participants with experience of switching DMT, eight had taken two or more DMTs; eight had taken three or more. Two was the DMT median. This study demonstrated that despite the term "switching" implying that similar treatments are inter-changeable, for pwRRMS taking new treatments involves different emotions, routines, risks, prognosis and communication experiences. Two meta themes identified were: 1) A distinctive, rapid and emotional decision-making process where old emotions related to MS prognosis are revisited. 2) Switching has a different impact on communication for escalation or de-escalation processes.

CONCLUSION

Switching DMT involves different routines, risks, prognosis and communication experiences. These decisions are emotionally difficult because of the fear about transitioning to secondary progressive MS, and DMT effectiveness uncertainty. Patient centred decision aids should include information about first and consecutive treatment decisions.

Support Group Participation: Effect on Perceptions of Patients with Newly Diagnosed Multiple Sclerosis

Background

Patients newly diagnosed as having multiple sclerosis (MS) face an overwhelming number of questions about how it will affect their lives. Participation in a support group is one way to obtain information and receive support from others. However, existing support groups are often attended by patients with significant disability, resulting in newly diagnosed patients being hesitant to return.

Methods

This qualitative pilot study explored perceptions of patients with newly diagnosed MS before and after participation in two monthly meetings. A support group was conducted each month using nursing staff, a physician, and a social worker. Prior to the first meeting, participants were asked to complete a questionnaire with open-ended questions to share their thoughts about how MS may affect their lives. After the two meetings, they were asked to complete the same questionnaire again.

Results

Eight themes were identified: uncertain disease course; insecure future; physical, emotional, and cognitive impacts; effect on relationships with family and/or spouse/significant other; ability to develop future relationship with significant other; impact on career plans; impact on ability to achieve future goals; and impact on ability to care for self and family. Five of six participants who attended both meetings and one of four who attended only the first meeting expressed a change in their perception of how MS may affect their lives.

Conclusions

A support group dedicated exclusively to newly diagnosed patients may provide an opportunity for patients to experience a change in perceptions of MS.

'It struck at the heart of who I thought I was': A meta-synthesis of the qualitative literature examining the experiences of people with multiple sclerosis

Background

People with multiple sclerosis (MS) have varied experiences and approaches to self‐management. This review aimed to explore the experiences of people with MS, and consider the implications of these experiences for clinical practice and research.

Methods

A meta‐synthesis of the qualitative literature examining experiences of people with MS was conducted using systematic searches of ProQuest, PubMed, CINAHL and PsycINFO. We incorporated feedback from team members with MS as expert patient knowledge‐users to capture the complex subjectivities of persons with lived experience responding to research on lived experience of the same disease.

Results

Of 1680 unique articles, 77 met the inclusion criteria. We identified five experiential themes: (a) the quest for knowledge, expertise and understanding, (b) uncertain trajectories (c) loss of valued roles and activities, and the threat of a changing identity, (d) managing fatigue and its impacts on life and relationships, and (f) adapting to life with MS. These themes were distributed across three domains related to disease (symptoms; diagnosis; progression and relapse) and two contexts (the health‐care sector; and work, social and family life).

Conclusion

The majority of people in the studies included in this review expressed a determination to adapt to MS, indicating a strong motivation for people with MS and clinicians to collaborate in the quest for knowledge. Clinicians caring for people with MS need to consider the experiential and social outcomes of this disease such as fatigue and the preservation of valued social roles, and incorporate this into case management and clinical planning.
