Health-related quality of life among informal caregivers assisting people with multiple sclerosis

Mapping Resilience: Structural Equation Modeling of Psychological Resilience in Multiple Sclerosis Care Partners

BACKGROUND

Care partners are essential supports to individuals with multiple sclerosis (MS). Both negative and positive outcomes associated with the caregiving role have been reported. Psychological resilience may be an important factor influencing the MS caregiving experience, but an MS-specific model of care partner resilience has yet to be established. This study sought to explore an explicit model of MS care partner resilience.

METHODS

Cross-sectional data from 471 Canadian MS care partners were collected via an online survey. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used to test measures within a hypothesized model of resilience. Resilience was measured using the 25-item Connor-Davidson Resilience Scale.

RESULTS

Following CFA, the hypothesized model was simplified due to the poor fit of several variables. The final model yielded a moderate SEM fit (χ2 = 6030.95, P < .01). Being a woman was associated with greater caregiving tasks (β = 0.53, P < .001) and poorer spiritual health (β = -0.35, P < .001). Spiritual health, but not caregiving tasks, had a positive impact on both positive (β = 0.48, P < .01) and negative coping (β = 0.49, P = .01). Quality of life and resilience did not have relationships with other variables in the model. However, quality of life had a positive, unidirectional influence on resilience (β = 0.83, P < .01).

CONCLUSIONS

Our findings indicate that spiritual health is an important predictor of coping and should be further explored in MS care partners. Quality of life may act as a precursor to resilience within MS care partners. Further research and exploration into MS care partner resilience is warranted to confirm this exploratory model.

Burden and resources in caregivers of people with multiple sclerosis: A qualitative study

BACKGROUND

Caregivers of people with Multiple Sclerosis are required to provide ongoing assistance especially during the advanced stages of the disease. They have to manage interventions and assume responsibilities which significantly impact both their personal quality of life and family's dynamics.

OBJECTIVE

A qualitative phenomenological study was carried out to understand the experience of burden in caregivers and their resources to manage it. The study also explores how healthcare services involved in the Multiple Sclerosis Clinical Pathway respond to the needs of well-being of patients and family members.

METHODS

17 caregivers were involved in focus groups and in semi-structured individual interviews.

RESULTS

Fatigue is experienced by all respondents and it starts when physical disabilities increase or when people become aware of them. Many caregivers declare that they refer to intrinsic (love towards their relatives, patience and dedication) or extrinsic (family members, hobbies) resources to cope with the burden of assistance. Patient associations and the Multiple Sclerosis Clinical Pathway play a significant role in supporting caregivers.

CONCLUSIONS

Fatigue, loneliness, and isolation are experienced by caregivers and strongly affect their quality of life and health status. The study highlights caregivers' need to reconcile working times with care times, to give more space to self-care and to have moments to share their experiences with someone else. These needs should be at the core of health policies in order to avoid physical and emotional breakdowns which could lead to the rupture of the relational balance on which home care is based.

Needs of informal caregivers of people with a rare disease: a rapid review of the literature

OBJECTIVES

Many people living with a rare disease (RD) are cared for by a family member. Due to a frequent lack of individual RD knowledge from healthcare professionals, the patient and their informal caregiver are frequently obliged to become 'experts' in their specific condition. This puts a huge strain on family life and results in caregivers juggling multiple roles in addition to unique caring roles including as advocate, case manager and medical navigator. We conducted a rapid review of literature reporting on the unmet needs of informal caregivers for people living with an RD. All searches were conducted on 14 September 2021, followed by a manual searches of reference lists on 21 September 2021.

SETTING

Searches were conducted in Medline, Embase, Web of Science, GreyLit and OpenGrey.

RESULTS

Thirty-five papers were included in the final review and data extracted. This rapid review presents several unmet needs identified by informal caregivers of persons with an RD. The related literature was organised thematically: caregiver burden, support through the diagnosis process, social needs, financial needs, psychological needs, information and communication needs and acknowledgement from healthcare professionals.

CONCLUSIONS

This review provides evidence that increased meaningful support is required for caregivers. Active engagement should be encouraged from this cohort in future research and awareness raised of the support available to improve the quality of life for families living with an RD. The unmet needs identified through this review will benefit people living with an RD, caregivers, healthcare professionals and policy makers.

The effect of nurse practitioner (NP-led) care on health-related quality of life in people with multiple sclerosis - a randomized trial

Background

Care for People with Multiple Sclerosis (PwMS) is increasingly complex, requiring innovations in care. Canada has high rates of MS; it is challenging for general neurologists to optimally care for PwMS with busy office practices. The aim of this study was to evaluate the effects of add-on Nurse Practitioner (NP)-led care for PwMS on depression and anxiety (Hospital Anxiety and Depression Scale, HADS), compared to usual care (community neurologist, family physician).

Methods

PwMS followed by community neurologists were randomized to add-on NP-led or Usual care for 6 months. Primary outcome was the change in HADS at 3 months. Secondary outcomes were HADS (6 months), EQ5D, MSIF, CAREQOL-MS, at 3 and 6 months, and Consultant Satisfaction Survey (6 months).

Results

We recruited 248 participants; 228 completed the trial (NP-led care arm n = 120, Usual care arm n = 108). There were no significant baseline differences between groups. Study subjects were highly educated (71.05%), working full-time (41.23%), living independently (68.86%), with mean age of 47.32 (11.09), mean EDSS 2.53 (SD 2.06), mean duration since MS diagnosis 12.18 years (SD 8.82) and 85% had relapsing remitting MS. Mean change in HADS depression (3 months) was: -0.41 (SD 2.81) NP-led care group vs 1.11 (2.98) Usual care group p = 0.001, sustained at 6 months; for anxiety, − 0.32 (2.73) NP-led care group vs 0.42 (2.82) Usual care group, p = 0.059. Other secondary outcomes were not significantly different. There was no difference in satisfaction of care in the NP-led care arm (63.83 (5.63)) vs Usual care (62.82 (5.45)), p = 0.194).

Conclusion

Add-on NP-led care improved depression compared to usual neurologist care and 3 and 6 months in PwMS, and there was no difference in satisfaction with care. Further research is needed to explore how NPs could enrich care provided for PwMS in healthcare settings.

Multiple sclerosis caregiving: A systematic scoping review to map current state of knowledge

Unpaid caregivers, typically family and friends, provide significant amounts of support to people with multiple sclerosis (MS). Understanding their experiences, needs and challenges is necessary to ensure that caregivers receive the support that they require to continue in their role. Our aim was to map the current state of knowledge about unpaid caregivers of people with MS and identify gaps in knowledge to guide future research and practice. We used scoping review methodology with three major health-related databases (MEDLINE, CINAHL, APA Psychinfo), searching in September 2019, April and October 2020 and October 2021. We selected peer-reviewed scientific articles reporting on primary studies of unpaid caregivers of people with MS, regardless of topic or research design. We extracted information on study aim, participant characteristics, measures used and key findings to generate major themes and identify knowledge gaps. We identified 108 published studies between 1992 and 2021 that met our criteria. Studies of spousal caregivers were most common. Studies focused primarily on measurement of caregiver burden or other negative consequences of caregiving. Thirteen studies addressed positive consequences of caregiving. Sixteen studies reported actual tasks performed by caregivers and seven reported outcomes of caregiver support interventions. Attention to diversity issues that may influence caregiving experiences and outcomes was rare. Overall, knowledge of MS caregiving is limited, particularly with respect to tasks performed by caregivers that may contribute to negative outcomes, diversity issues and effective approaches to remediate caregiver burden. Without this knowledge, finding ways to better support MS caregivers will be difficult.

Measuring the effects of nurse practitioner (NP)-led care on depression and anxiety levels in people with multiple sclerosis: a study protocol for a randomized controlled trial

Background

Canada has one of the highest rates of multiple sclerosis (MS) in the world. Treatments and supports for people with MS (PwMS) have become increasingly complex, requiring individualized and adaptive care. Specialized NPs provide advanced skills to those with complex medical conditions, with potential to enhance the health, functioning, and quality of life for PwMS. This study aims to determine the effect of a Nurse Practitioner (NP) on depression and anxiety levels in PwMS.

Methods

We will perform a parallel randomized controlled trial. PwMS who are followed by general private-practice neurologists will be randomly assigned to the intervention group (NP-led care) or the ‘usual care’ control group (general neurologist or family physician and registered nurse support). In the intervention group, the NP will assess and provide care to the MS patient and their caregiver at a baseline visit, with 3-month and 6-month follow-up visits. PwMS in the control group will receive usual care provided by their community neurologists or family physicians with the standard assistance provided by registered nurses experienced in MS care. The primary outcome will be the difference in change in the patient’s anxiety and depression scores as measured by the validated Hospital Anxiety and Depression Scale (HADS) questionnaire at 3 months. Secondary outcomes will include difference in change in HADS at 6 months; Modified Fatigue Impact Scale scores (MSIF) at 3 and 6 months; EQ-5D scores at 3 and 6 months; caregiver health-related quality of life in MS measures (CAREQOL-MS) at 3 and 6 months; number of visits and phone calls to healthcare professionals recorded by patient, and satisfaction with NP-led care vs usual care measured by the validated Consultant Satisfaction Questionnaire.

Discussion

Findings from this study will contribute to exploring benefits of advanced nursing practitioner interventions for PwMS followed by general neurologists and family physicians in a community setting. It will provide evidence of the benefits of NP-led care for PwMS and offer an alternative healthcare resource for management of MS.

Informal carers' experiences of caring for someone with Multiple Sclerosis: A photovoice investigation

OBJECTIVES

This study explores the lived experiences of carers of people with Multiple Sclerosis (MS), specifically in relation to their quality of life (QoL), through the use of images and narratives, with the aim of gaining a nuanced insight into the complex nature of QoL in the MS caregiving context.

DESIGN

Real-time qualitative design using the photovoice method.

METHODS

Twelve MS carers (aged 30-73 years) took photographs of objects/places/events that represented enhancement or compromise to their QoL and composed written narratives for each photograph based on their experiences of caregiving. In total, 126 photographs and their corresponding narratives were analysed using content analysis.

RESULTS

Seven inter-related themes were identified. MS caregiving-related challenges, sense of loss (e.g., loss of activities), emotional impact (e.g., feeling lonely), urge to escape, and sense of anxiety over the unpredictability of MS carer role were discussed in relation to the negative experiences that compromised their QoL. The themes precious moments (e.g., time spent with loved ones or hobbies) and helpful support (e.g., family and pets) encompassed participants' positive experiences that enhanced their QoL.

CONCLUSIONS

Findings demonstrated the multi-faceted and complex nature of MS caregiver's QoL and highlighted that although the experiences of MS carers were mostly negative, there were also some positive aspects to caregiving, that helped enhance carers' QoL by ameliorating these negative experiences. These findings can be used to inform support programmes and enhance service provision for MS carers.

Follow-Ups with callers of a palliative and hospice care hotline for severely affected multiple sclerosis patients: Evaluation of its impact

BACKGROUND

Palliative and Hospice Care (PHC) focuses on improving quality of life for anyone who has a serious illness. Multiple Sclerosis (MS) patients have significant PHC needs, yet PHC still mostly attends to cancer patients. The implemented and evaluated nationwide PHC-MS hotline (Strupp et al., 2017) appeared to provide a useful service to patients.

OBJECTIVES

Prospective follow-up study to evaluate the impact of the hotline and analyse challenges and possible barriers to integrating PHC services.

METHODS

Information on implementing PHC services was gathered through follow-up hotline consultations utilising a standardised documentary sheet. Data was analysed descriptively and several individual cases are presented.

RESULTS

Of 303 calls to the hotline (54.5% female, mean age 51 years, 87.7% chronic progressive MS, mean duration of illness 17 years, median EDSS 8), for 84 (27.7%) PHC services were indicated. Of these 84 patients, 32 agreed to follow-up calls which were conducted at least once. For 6 (19%) patients, PHC service integration was successful. For 5 (16%) PHC was refused. For 5 (16%) PHC did not fit current patient needs, and for 7 (22%) PHC has not yet been contacted by patients (or caregivers). For a further 9 (28%) follow-ups revealed that no more consultation was possible (e.g., caller lost to follow-up).

CONCLUSION

The PHC approach and its services as well as legislation are still highly focused on cancer care, although patients with long-term neurological conditions would likely benefit greatly from them.

Quality of Life and Emotional Strain in Caregivers of Patients with Multiple Sclerosis

Background and Purpose

This study aimed was to measure the quality of life, fatigue, stress, and depression in a consecutive sample of caregivers of multiple sclerosis (MS) patients.

Methods

We included data from 131 consecutive caregivers of MS patients [age=51.2±12.8 years (mean±SD), males=53.4%, duration of caregiving=10.0±6.3 years]. We assessed the quality of life, fatigue, stress, and depression of the caregivers using the 36-item Short Form Health Survey, Krupp Fatigue Severity Scale, Kingston Caregiver Stress Scale, and Hamilton Scale for Depression, respectively. The disability status of the patients was assessed using the Kurtzke Expanded Disability Status Scale. We used linear regression models to identify possible correlations between all of the aforementioned scales, while multivariable logistic regression models were employed to assess the correlations of caregiver fatigue with caregiver characteristics and patient disability.

Results

The linear regression analyses revealed that caregiver fatigue was positively associated with stress and negatively correlated with both physical health status and mental health status. Caregiver stress was positively associated with depression and negatively correlated with both physical health status and mental health status. Depression was negatively correlated with both caregiver physical health status and mental health status. In multivariable logistic regression analysis, caregiver fatigue was found to be independently associated with education status [odds ratio (OR)=0.61, 95% CI=0.37 to 0.99], history of chronic disease (OR=5.52, 95% CI=1.48 to 20.55), other chronic diseases in the family (OR=7.48, 95% CI=1.49 to 37.47), and the disability status of the patient (OR=1.36, 95% CI=1.03 to 1.80).

Conclusions

Fatigue, stress, and depression in caregivers of MS patients are negatively correlated with their physical health status and mental health status. Caregiver fatigue is independently associated with education status, history of chronic disease, other chronic disease in the family, and patient disability.

The Economic and Social Impact of Informal Caregivers at Mulago National Referral Hospital, Kampala, Uganda

BACKGROUND

The severe deficit of health care workers in Uganda necessitates hospitalized patients to be cared for by a relative. These informal caregivers constitute a crucial component of patient care. Mulago Hospital in Kampala, Uganda, is one of the nation's national referral hospitals, receiving very sick patients. Although studies have been conducted on challenges facing informal caregivers in the home setting, no study has addressed the caregiver burden in the hospital setting.

METHODS

A survey of 100 randomly selected informal caregivers was conducted in Mulago Hospital's internal medicine wards to evaluate informal caregivers' demographics, impact on patient care, and challenges.

RESULTS

Challenges include emotional burdens, lack of sanitation, accommodation, sufficient health workers, finances, and recognition. Recommendations were given to ensure improve informal caregivers' situations.

CONCLUSIONS

Despite hardships, informal caregivers recognize the importance of familial presence, thereby setting a new standard for patient care by recreating the comfort of home care in the hospital. Studying the characteristics of these care givers and more fully delineating the sacrifices they make and the challenges they faced provides the basis for a series of recommendations to hospital management aimed both at improved patient care and care of the informal caregiver.

Gender differences in caregiver strain, needs for support, social support, and quality of life among spousal caregivers of persons with multiple sclerosis

BACKGROUND

Caregivers of individuals with MS may experience unique caregiver strain due to the age at onset and progressive nature of the disease. Additionally, because MS is more prevalent in women, men often become spousal caregivers. However, gender differences in psychosocial adjustment among caregivers have not been fully explored.

OBJECTIVE

The purpose of this study was to explore gender differences in the need for various supports and type of social support needed, caregiver strain, and quality of life among caregivers for individuals with MS.

METHODS

106 caregivers participated in this study. Independent sample t-tests and multiple regression analyses were conducted to examine gender differences in strain, need for supports, social support, and quality of life.

RESULTS

Analyses revealed gender difference among important psychosocial variables. Specifically, women reported higher levels of caregiver strain, higher needs for emotional support, and higher perceived social support. Additionally, multiple regression analyses revealed an inverse relationship between expressed emotional needs and quality of life for men, but not for women.

CONCLUSIONS

MS caregivers experience significant strain that diminishes quality of life. Social support and needs fulfillment can act to buffer this stress; however, results indicate that this varies by gender, with gender differences observed in strain, perceived support, and expressed needs among MS caregivers. The study implications for rehabilitation research are discussed.

Predictors of burden and depression among caregivers of relapsing-remitting MS patients in Spain: MS Feeling study

AIM

To assess potential predictors for burden and depression among caregivers of relapsing-remitting multiple sclerosis patients in Spain. Family functioning and social support were also assessed.

PATIENTS & METHODS

Multicenter and cross-sectional study in relapsing-remitting multiple sclerosis adult patients and their respective informal caregivers (n = 180). Assessment performed: Zarit Scale (Burden), Center for Epidemiologic Studies Depression-7 Scale (depression), Family APGAR (Adaptation, Partnership, Growth, Affection, Resolve) Questionnaire (family functioning) and Duke UNC-11 Functional Social Support Questionnaire (social support). Multivariate logistic regression analysis assessed burden and depression predictors among caregivers.

RESULTS

Caregivers suffered burden (19.4%) and depression (20.6%) and perceived poor social support (9.4%) and family dysfunction (10.6%). Burden predictors were patient's degree of disability, caregiver time and number of medications administered to patient. Depression predictors were patient's age and daily caregiving time.

CONCLUSION

The factors reported here could help clinicians to identify caregiver groups particularly at risk of burden and depression for timely intervention.

If they are OK, we are OK: the experience of partners living with neuromyelitis optica

AIM

Neuromyelitis optica (NMO) is a rare neuro-inflammatory condition characterized by acute relapses causing severe visual or physical disability. The impact on family members and their experiences have not been studied. The study aims were to explore the lived experience of partners of people with NMO and to investigate potential carer burden in this population.

METHOD

A mixed-method design was used; 11 partners of people with NMO completed semi-structured interviews; 54 partners completed Zarit Burden Interview and Hospital Anxiety and Depression Scale.

RESULTS

Three qualitative themes influenced partners' quality of life (QoL): role/relationship; it's all about them; and the impact of NMO. Life changed dramatically for participants after the first NMO attack, necessitating responsibility for physical, financial, social, and emotional support. As NMO symptoms improved and stabilized, freedom and QoL for spouses also improved, albeit with on-going worries regarding the impact of potential devastating future relapses. Quantitative findings showed mild/moderate carer burden (46%), mild/moderate anxiety (59%), and mild/moderate depression (24%). No partner indicated severe carer burden, anxiety, or depression.

CONCLUSION

Participants regarded themselves as partners rather than carers whom require assessment and support for their emotional and health well-being. Health-care professionals need to acknowledge the important role partners play in the dynamics of the family unit, through greater discussion and inclusion. Implications for Rehabilitation NMO has a strong impact on couples, resulting in both physical caregiving needs and anxiety regarding the unpredictability of potential devastating relapses. Partners do not necessarily experience clinically significant "burden", anxiety or depression, and tools which screen for this may not capture the nature of their experiences. Health-care professionals need to acknowledge, consult, and respect the experience of partners during assessment and implementation of action plans. Partners should be individually assessed based upon the physical and emotional dependency created by NMO to improve their health and well-being.

Mental Health and Health-Related Quality of Life in Multiple Sclerosis Caregivers in Mexico

BACKGROUND

Multiple sclerosis (MS) rates are increasing in Latin America, and caregiving for an individual with MS is associated with poorer mental and physical health outcomes. No existing research has examined the relation between mental health and health-related quality of life (HRQOL) in MS caregivers in Latin America.

METHODS

The present study examined the association between mental health (Patient Health Questionnaire-9, Satisfaction with Life Scale, Rosenberg Self-esteem Scale, State-Trait Anxiety Inventory) and HRQOL (36-item Short Form Health Status Survey) in 81 Mexican MS caregivers.

RESULTS

A canonical correlation analysis uncovered a large, significant overall association between mental health and HRQOL, with 52.7% of the variance shared between the two sets of constructs. When individual canonical loadings were examined in this analysis, the most substantial pattern that emerged was between depression and general health. Four regressions controlling for demographic variables found that HRQOL uniquely accounted for 19.0% of the variance in caregiver anxiety, 32.5% in depression, 13.5% in satisfaction with life, and 14.3% in self-esteem.

CONCLUSIONS

These findings demonstrated a strong association between HRQOL and mental health, which points to directions for future studies on interventions for MS caregivers, particularly in Mexican and other Latino populations.

Perceptions of caregiver distress, health behaviors, and provider health-promoting communication and their relationship to stress management in MS caregivers

This study applied the Stress/Health Model to examine a novel approach for promoting stress management among 67 caregivers of persons with multiple sclerosis, who often face unique caregiving challenges. Hierarchical regressions indicated that caregiver distress (i.e., emotional burden) and engagement in other health-promoting activities (i.e., controlling alcohol use) were the best predictors of caregiver stress management. Communication with the MS care recipient's health provider about caregiver engagement in health-promoting activities was associated with caregiver stress management, but not significantly more so than explained by the other factors (i.e., caregiver distress and engagement in health-promoting behaviors). A more controlled study would be indicated to further explain how to encourage, within the medical setting, caregiver engagement in self-care activities.

Unmet needs of caregivers of severely affected multiple sclerosis patients: A qualitative study

OBJECTIVE

Multiple sclerosis (MS) patients' caregivers are sometimes considered as "hidden patients." How much more this might be true for caregivers of severely affected MS patients has so far been scarcely studied. Palliative care also addressing relatives' needs might therefore be very relevant for these caregivers. However, we do not yet know which unmet needs they have and how these could be met. Our aim was to gain an insight into the subjectively unmet needs of caregivers of severely affected MS patients in Germany.

METHOD

The study employed a qualitative cross-sectional approach for assessing unmet needs. Twelve caregivers of severely affected MS patients were recruited using a convenience sampling approach. Face-to-face interviews were conducted, audiotaped, and transcribed verbatim, followed by qualitative content analysis.

RESULTS

Unmet needs were sorted into the following categories: "relationship to physician," "individual support by the healthcare system," "relationship to the individual severely affected by MS," "end-of-life issues," "self-care," and "higher awareness of MS." Caregivers tended to group the unmet needs of their care recipients with their own and rarely focused on their own wishes and restrictions.

SIGNIFICANCE OF RESULTS

A close patient-caregiver dyad makes it difficult to differentiate unmet caregiver needs. However, the palliative care approach might help caregivers of severely affected MS patients by answering questions on disease progress and end-of-life issues, as well as by offering respite care, support for self-care, and help in preserving one's identity, and also anticipating the time to come after the death.

Multiple sclerosis in US minority populations: Clinical practice insights

The heterogeneity of multiple sclerosis (MS) characteristics among various ethnic minority populations is a topic of recent interest. However, these populations are consistently underrepresented in clinical trials, leading to limited data on the effectiveness of treatments in these groups of patients and lack of an evidence-based approach to treatment. In order to achieve optimal disease management in the ethnic minority MS populations, a better understanding of the regional, socioeconomic, and cultural influences that result in underrepresentation of these groups in clinical trials is needed. Furthermore, it would be beneficial to identify the genetic factors that influence disease disparity in these minority populations. Suggestions for the identification and implementation of best practices for fostering the trust of ethnic minority patients with MS and enhancing their participation in clinical trials are offered.

The impact of multiple sclerosis on family members: a review of the literature

Multiple sclerosis (MS) is one of the most common neurological diseases in young adults and involves inflammatory demyelination of the CNS. MS typically manifests between 20 and 40 years of age, and can lead to significant disability in some cases. The disease course is unpredictable. MS has a significant impact on families, influencing their wellbeing and quality of life, often creating psychological stress in each family member as well as on family functioning in general. Common themes include the impact of the emotional state of the person with MS on family members, the role of the healthy parent on how children cope, the effect of a lack of information about MS, communication within the family and with healthcare professionals, and the importance of assessing and treating families as a dynamic unit in order to assure comprehensive intervention plans. The current literature review is based on 30 full research articles meeting inclusion criteria related to partners/couples, family caregivers, children with a parent with MS and parents of young children with MS.

Islamic fasting and multiple sclerosis

Background

Month-long daytime Ramadan fasting pose s major challenges to multiple sclerosis (MS) patients in Muslim countries. Physicians should have practical knowledge on the implications of fasting on MS. We present a summary of database searches (Cochrane Database of Systematic Reviews, PubMed) and a mini-symposium on Ramadan fasting and MS. In this symposium, we aimed to review the effect of fasting on MS and suggest practical guidelines on management.

Discussion

In general, fasting is possible for most stable patients. Appropriate amendment of drug regimens, careful monitoring of symptoms, as well as providing patients with available evidence on fasting and MS are important parts of management. Evidence from experimental studies suggests that calorie restriction before disease induction reduces inflammation and subsequent demyelination and attenuates disease severity. Fasting does not appear to have unfavorable effects on disease course in patients with mild disability (Expanded Disability Status Scale (EDSS) score ≤3). Most experts believed that during fasting (especially in summer), some MS symptoms (fatigue, fatigue perception, dizziness, spasticity, cognitive problems, weakness, vision, balance, gait) might worsen but return to normal levels during feasting. There was a general consensus that fasting is not safe for patients: on high doses of anti-convulsants, anti-spastics, and corticosteroids; with coagulopathy or active disease; during attacks; with EDSS score ≥7.

Summary

These data suggest that MS patients should have tailored care. Fasting in MS patients is a challenge that is directly associated with the spiritual belief of the patient.

A forgotten aspect of the NICE reference case: an observational study of the health related quality of life impact on caregivers of people with multiple sclerosis

Background

There are few published health technology assessments that have included the impact of a disease or treatment on caregivers’ health related quality of life (HRQL). The objectives of this study were to explore the overall HRQL of caregivers of people with Multiple Sclerosis compared to matched controls, and more specifically explore the impact of different levels of functioning in people with MS on caregivers’ HRQL scores.

Methods

A cross sectional observational study conducted as an online survey was undertaken in the UK. 200 caregivers of people with MS and 200 matched controls completed the EQ-5D, SF-36, HADS and a socio-demographic questionnaire. Caregivers also completed the Patient Determined Disease Steps questionnaire as a measure of MS severity. Differences in HRQL between caregivers and controls were assessed using t-tests and chi square analyses as appropriate. Ordinary Least Squares regression was also used to evaluate the disutility of being a caregiver compared to controls stratified by MS severity.

Results

Caregivers reported significantly lower HRQL, as measured by the SF-36, HADS and EQ-5D, compared to matched controls. A lower level of functioning in people with MS was mirrored by lower levels of caregivers’ HRQL. At the point at which mobility problems required wheelchair use caregivers reported better HRQL.

Conclusions

The potential impact of caregiving on HRQL is an important consideration for economic evaluations. In relation to MS, the results suggest that caregiver’s HRQL deteriorates as the people with MS lose functioning; thus treatments that delay loss of function may have a benefit for caregivers as well as patients.

Cost-minimization analysis of fingolimod compared with natalizumab for the treatment of relapsing-remitting multiple sclerosis in Sweden

BACKGROUND

Fingolimod and natalizumab have the same European Union licence for the treatment of relapsing multiple sclerosis, and are considered by the Committee for Medicinal Products for Human Use (CHMP) to have broadly similar efficacy.

OBJECTIVE

A cost-minimization analysis was performed to compare differences in treatment costs between fingolimod and natalizumab from a societal perspective in Sweden.

METHODS

This analysis included costs associated with initiating and following treatment (physician visits and monitoring), continuing therapy (drugs and administration), and lost patient productivity and leisure time. Unit costs (in Swedish krona [SEK]) were based on regional data (median prices for physician visits and monitoring sessions). Natalizumab infusion costs were obtained from the national cost-per-patient database. Drug costs for both therapies were 15,651 SEK/28 days.

RESULTS

After 3 years, fingolimod use was associated with savings of 124,823 SEK/patient compared with natalizumab (total cost/patient: 566,718 SEK vs 691,542 SEK). Cost savings with fingolimod were 40,402 SEK/patient after 1 year and 301,730 SEK/patient after 10 years. Treatment with natalizumab was 18% more expensive than fingolimod therapy after 1 year and 23% more expensive after 10 years.

LIMITATIONS

Based on the CHMP assessment, it was assumed that fingolimod and natalizumab have similar efficacy. The analysis was conducted for Sweden, and caution is needed in extrapolating the results to other countries.

CONCLUSION

Fingolimod is cost-saving compared with natalizumab for the treatment of relapsing-remitting multiple sclerosis in Sweden.

Social and economic burden of walking and mobility problems in multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is a chronic progressive neurological disease and the majority of patients will experience some degree of impaired mobility. We evaluated the prevalence, severity and burden of walking and mobility problems (WMPs) in 5 European countries.

METHODS

This was a cross-sectional, patient record-based study involving 340 neurologists who completed detailed patient record forms (PRF) for patients (>18 years) attending their clinic with MS. Patients were also invited to complete a questionnaire (PSC). Information collected included demographics, disease characteristics, work productivity, quality of life (QoL; EuroQol-5D and Hamburg Quality of Life Questionnaire Multiple Sclerosis [HAQUAMS]) and mobility (subjective patient-reported and objectively measured using the timed 25 foot walk test [T25FW]). Relationships between WMPs and disease and other characteristics were examined using Chi square tests. Analysis of variance was used to examine relationships between mobility measures and work productivity.

RESULTS

Records were available for 3572 patients of whom 2171 also completed a PSC. WMPs were regarded as the most bothersome symptom by almost half of patients who responded (43%; 291/683). There was a clear, independent and strong directional relationship between severity of WMPs (subjective and objective) and healthcare resource utilisation. Patients with longer T25FW times (indicating greater walking impairment) were significantly more likely to require additional caregiver support (p < 0.0001), visit a variety of healthcare professionals including their primary care physicians (p = 0.0044) and require more long-term non-disease modifying drugs (p = 0.0001). A similar pattern was observed when subjective reporting of the severity of WMPs was considered. Work productivity was also markedly impacted by the presence of WMPs with fewer patients working full time and a reduction in weekly working hours as T25FW times and the subjective severity of WMPs increased.

CONCLUSIONS

In Europe, WMPs in MS represent a considerable personal and social burden both financially and in terms of quality of life. Interventions to improve mobility could have significant benefits for patients and society as a whole.

Walking impairment in patients with multiple sclerosis - a new therapeutic approach and clinical potential of dalfampridine extended release tablets

Walking impairment is a clinical hallmark of multiple sclerosis (MS) that has been under-recognized as a therapeutic target for pharmacologic intervention. The development and approval of dalfampridine extended release tablets (dalfampridine-ER; known as prolonged-, modified, or sustained-release fampridine outside the USA), 10 mg taken twice daily, to improve walking in patients with MS, fills a previously unmet need. In three randomized, double-blind, placebo-controlled trials, dalfampridine-ER improved walking speed in approximately one-third (37%) of treated patients, and average walking speed on therapy among these responders improved by approximately 25% relative to baseline. Walking-speed improvement among responders was clinically significant, as determined by a statistically significant improvement in the patient-reported 12-item Multiple Sclerosis Walking Scale. Long-term extension studies indicate that responders were able to maintain benefits, compared with nonresponders over prolonged periods of treatment. Dalfampridine-ER was generally well tolerated. Dizziness, insomnia, balance disorder, headache, nausea, urinary tract infection, and asthenia were the most common adverse events. Although the incidence of seizures appeared to be dose related, among patients treated with dalfampridine-ER in the three trials, the rate of seizures was 0.25%. These efficacy and safety data suggest that dalfampridine-ER can be a useful and clinically relevant addition to the pharmacologic armamentarium for the management of MS symptoms and disabilities. Because of its narrow therapeutic index and potential for seizures, it is especially important in the clinical setting to adhere to the dosing recommended in the approved labels.

Health-related quality of life and depressive symptoms in significant others of people with multiple sclerosis: a community study

BACKGROUND AND PURPOSE

 Uncertain prognosis and modest treatment efficacy make multiple sclerosis (MS) a particularly difficult disease to adjust to for both patients and their significant others (SOs). Few studies have assessed health-related quality of life (HRQOL) and depressive symptoms in SOs of people with MS in the community. We assessed, and identified predictors of, HRQOL and depression in SOs of adults with MS.

METHODS

  POSMOS (postal survey of self-assessed health in MS adults and SOs) is a longitudinal survey on a random sample of 251 people with MS in the Milan area. In 2010, SOs and contemporaneous controls completed the SF-36 and Chicago Multiscale Depression Inventory (CMDI).

RESULTS

  Overall, 142 SOs (mean age 53.1 years; 50% women, 65% partners) and 120 controls (similar to SOs for sex and education, but older) participated. By multivariable modeling of the SO plus control population, SF-36 vitality was lower in SOs (proportional odds ratio 0.45; 95% confidence interval 0.28-0.70), women (0.41; 0.27-0.64), and older subjects (0.98; 0.97-0.99). SF-36 mental health was also lower in SOs (0.62; 0.40-0.96) and women (0.43; 0.28-0.67). Regarding MS characteristics associated with HRQOL and depression in SOs, severe disability [Expanded Disability Status Scale (EDSS > 6.5)] had no effect, whilst depressive symptoms (pathologic CMDI) negatively influenced most SF-36 and all CMDI scores in SOs.

CONCLUSIONS

  SOs had significantly lower vitality and psychological well-being than controls, identifying a burden in being the companion of a person with MS. This burden was unrelated to physical compromise but associated with depressive symptoms in MS.
