Utilization of Multiple Sclerosis Therapies in the Middle East Over a Decade: 2009-2018

Temporal and spatial patterns in the prescriptions of disease-modifying therapies for multiple sclerosis. Results from the Italian Multiple Sclerosis and Related Disorders Register

BACKGROUND

The therapeutic scenario in multiple sclerosis (MS) has evolved over recent years with the progressive introduction of new drugs focused to better balance efficacy, safety and management requirements. The objective of this study was to examine the prescribing patterns of disease-modifying therapies (DMT) over time and across different geographic areas, and the latency between disease onset, first Register center visit, disease diagnosis, and the start of treatment in a large cohort of persons with MS from the Italian Multiple Sclerosis and Related Disorders Register.

METHODS

Up to 2022, the Register collected data from 124 centers on more than 78,000 persons, of whom 56,872 received at least one DMT prescription. Beside baseline demographic and clinical characteristics, we focused on DMT according to their efficacy distinguishing between moderate-efficacy (ME), or high-efficacy (HE).

RESULTS

There was a higher probability of prescribing HE-DMT for increasing calendar years (multivariable odds ratio, OR=11.51 in 2021 or thereafter vs before 2000), in males (OR=1.08 vs females), patients with primary progressive with or without relapse (OR=3.00 vs clinically isolated syndrome), those with a higher Expanded Disability Status Scale score (OR=3.85 for >4 versus 0-1), and those from larger referral centers (OR=1.89 vs smaller ones). Conversely, higher age at onset was associated to a lower probability of prescribing HE-DMT (OR=0.74 at 40 or more vs <20 years). A trend to shorter times was observed in subsequent calendar years for disease onset, first center visit, diagnosis and first DMT prescription. No trend was detected based on the location of the geographic referral centers. The times between disease onset, first center visit, and diagnosis and the first DMT prescription showed significant decreases according to the year, while differences were less evident for the geographic areas.

CONCLUSION

This study highlights some factors influencing the choice of HE-DMT, including aspects of both healthcare and clinical phenotype. The absence of a geographic pattern may indicate some homogeneity in DMT prescriptions across different Italian MS centers.

Treatment satisfaction with disease-modifying therapy is the only predictor of Adherence among multiple sclerosis patients from Upper Egypt

Despite the proven efficacy of the disease-modifying therapy (DMT) for multiple sclerosis (MS), the rates of non-adherence are frequently high. We aimed to evaluate the rate of non-adherence to the first DMT in Upper Egypt and identify different contributing factors. Out of 310 patients, ninety-seven adult patients with RRMS were recruited from three MS units located in Upper Egypt and were subjected to the following: complete clinical history, expanded disability status score (EDSS), Eight-item Morisky Medication Adherence Scale (MMAS-8), abbreviated Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9), Hamilton depression scale, Fatigue Severity Scale (FSS) and the Pittsburgh Sleep Quality Index (PSQI). According to MMAS-8 scores, 63 (64.9%) of patients were non-adherent to their first DMT. Non-adherent patients are more likely to have longer disease duration (p = 0.002), longer duration on first DMT (p = 0.030), first DMT-start date before 2019 (p = 0.040), and lower treatment satisfaction scores (p = 0.016). However, there was no significant relation with physical disability, depression, fatigue, or sleep quality. On the regression analysis model, a lower treatment satisfaction score was the only predictor of DMT non-adherence (p = 0.012). Despite expanding DMT options, non-adherence among MS patients in Upper Egypt is high. Treatment satisfaction with DMT is the only predictor of adherence among MS patients of Upper Egypt. Adherence and satisfaction with the prescribed DMT should be assessed carefully to maximize DMT benefits.

Current and future trends in multiple sclerosis management: Near East perspective

BACKGROUND

Multiple sclerosis (MS) prevalence is rising in the Middle East. Most MS medications are available in the region, but not all, possibly affecting neurologists' prescribing habits.

OBJECTIVES

To provide an overview of the current practices of Near East (NE) healthcare practitioners by probing their prescribing decisions, to report the COVID-19 impacts on neurologists' prescribing habits, and to explore the future relevance of current medication used in MS management among other newcomers.

METHODS

A cross-sectional study was carried out using an online survey from April 27, 2022, to July 5, 2022. The questionnaire was designed with the input of five neurologists representing five NE countries (Iran, Iraq, Lebanon, Jordan & Palestine). They identified several factors that play a crucial role in the optimal care of MS patients. The link was shared among neurologists using snowball sampling.

RESULTS

The survey included 98 neurologists. Effectiveness and safety balance was the most important factor considered when selecting the MS treatment. Among patients with MS, the most challenging factor for the patients was thought to be related to family planning, followed by affordability and tolerability of side effects. In the treatment of mild to moderate relapsing remitting multiple sclerosis (RRMS) in men, Interferon beta 1a SC, Fingolimod, and Glatiramer acetate were the most commonly recommended treatments. Dimethyl fumarate substituted fingolimod in female patients. Interferon beta 1a SC was the safest treatment for mild to moderate RRMS. Interferon beta 1a SC was preferred over other treatments for patients with mild to moderate MS and planning for pregnancy (56.6%) or breastfeeding (60.2%). Fingolimod was not a choice for these patients. Neurologists seemed to discuss the top three treatments of Natalizumab, Ocrelizumab, and Cladribine with patients with highly active MS. When asked to position future disease-modifying therapies five years from today, more than 45% of physicians expressed a lack of information on Bruton's tyrosine kinase (BTK) inhibitors.

CONCLUSIONS

Most neurologists in the NE region followed Middle East North Africa Committee for Treatment and Research in Multiple Sclerosis (MENACTRIMS) recommendations for prescribing treatment. The treatment choice also depended on the availability of disease-modifying therapies (DMTs) in the region. Regarding the use of upcoming DMTs, there is a clear need for real-world data, long-term extension studies, and comparative studies to support their efficacy and safety profiles in treating patients with MS.

Multiple sclerosis diagnostic delay and its associated factors in Upper Egyptian patients

The earlier the diagnosis of multiple sclerosis (MS), the sooner disease-modifying treatments can be initiated. However, significant delays still occur in developing countries. We aimed to identify factors leading to delayed diagnosis of MS in Upper Egypt. One hundred forty-two patients with remitting relapsing MS (RRMS) were recruited from 3 MS units in Upper Egypt. Detailed demographic and clinical data were collected. Neurological examination and assessment of the Disability Status Scale (EDSS) were performed. The mean age was 33.52 ± 8.96 years with 72.5% of patients were females. The mean time from symptom onset to diagnosis was 18.63 ± 27.87 months and the median was 3 months. Seventy-two patients (50.7%) achieved diagnosis within three months after the first presenting symptom (early diagnosis), while seventy patients (49.3%) had more than three months delay in diagnosis (delayed diagnosis). Patients with a delayed diagnosis frequently presented in the period before 2019 and had a significantly higher rate of initial non-motor presentation, initial non-neurological consultations, prior misdiagnoses, and a higher relapse rate. Another possible factor was delayed MRI acquisition following the initial presentation in sixty-six (46.5%) patients. Multivariable logistic regression analysis demonstrated that earlier presentation, initial non-neurological consultation, and prior misdiagnosis were independent predictors of diagnostic delay. Despite advances in MS management in Egypt, initial non-neurological consultation and previous misdiagnoses are significant factors responsible for delayed diagnosis in Upper Egypt.

External validation of a clinical prediction model in multiple sclerosis

BACKGROUND

Timely initiation of disease modifying therapy is crucial for managing multiple sclerosis (MS).

OBJECTIVE

We aimed to validate a previously published predictive model of individual treatment response using a non-overlapping cohort from the Middle East.

METHODS

We interrogated the MSBase registry for patients who were not included in the initial model development. These patients had relapsing MS or clinically isolated syndrome, a recorded date of disease onset, disability and dates of disease modifying therapy, with sufficient follow-up pre- and post-baseline. Baseline was the visit at which a new disease modifying therapy was initiated, and which served as the start of the predicted period. The original models were used to translate clinical information into three principal components and to predict probability of relapses, disability worsening or improvement, conversion to secondary progressive MS and treatment discontinuation as well as changes in the area under disability-time curve (ΔAUC). Prediction accuracy was assessed using the criteria published previously.

RESULTS

The models performed well for predicting the risk of disability worsening and improvement (accuracy: 81%-96%) and performed moderately well for predicting the risk of relapses (accuracy: 73%-91%). The predictions for ΔAUC and risk of treatment discontinuation were suboptimal (accuracy < 44%). Accuracy for predicting the risk of conversion to secondary progressive MS ranged from 50% to 98%.

CONCLUSION

The previously published models are generalisable to patients with a broad range of baseline characteristics in different geographic regions.

Unmet Needs and Treatment of Relapsing-Remitting Multiple Sclerosis in Saudi Arabia: Focus on the Role of Ofatumumab

Treatment-pattern data suggest that some patients with multiple sclerosis (MS) in the Kingdom of Saudi Arabia (KSA) may not be receiving optimal treatment. A virtual meeting of ten expert Saudi neurologists, held on October 23, 2020, discussed unmet needs in relapsing-remitting MS (RRMS), and the role of ofatumumab as a suitable treatment in the KSA. Multiple unmet needs were identified: poor quality of life, with high rates of depression and anxiety; a negative impact of MS on work ability; treatment choices that may compromise efficacy for safety or vice versa; inconvenient or complex dosage regimens; and limited access to patient education and support. Early use of highly effective disease-modifying treatments (DMTs) results in better patient outcomes than starting with less effective treatments and downstream escalation, but this strategy may be underutilized in the KSA. B cells are important in MS pathogenesis, and treatments targeting these may improve clinical outcomes. Ofatumumab differs from other B cell-depleting therapies, being a fully human monoclonal antibody that binds to CD20 at a completely separate site from the epitope bound by ocrelizumab, and being administered by subcutaneous injection. When compared with teriflunomide in two randomized, phase 3 clinical trials in patients with RRMS, ofatumumab was associated with significant reductions in annualized relapse rates, rates of confirmed disability worsening, and active lesions on magnetic resonance imaging. The incidence of adverse events, including serious infections, was similar with the two treatments. Ofatumumab is a valuable first- or second-line treatment option for RRMS in the KSA, particularly for patients who would benefit from highly effective DMTs early in the disease course, and for those who prefer the convenience of self-injection. Future research will clarify the position of ofatumumab in RRMS treatment, and comparative cost data may support the broad inclusion of ofatumumab in formularies across the KSA.

Do Hungarian multiple sclerosis care units fulfil international criteria?

A patients

Because of the past 3 decades’ extensive research, several disease modifying therapies became available, thus a paradigm change is multiple sclerosis care was necessary. In 2018 a therapeutic guideline was created recommending that treatment of persons with multiple sclerosis should take place in specified care units where the entire spectrum of disease modifying therapies is available, patient monitoring is ensured, and therapy side effects are detected and treated promptly. In 2019 multiple sclerosis care unit criteria were developed, emphasizing personnel and instrumental requirements to provide most professional care. However, no survey was conducted assessing the real-world adaptation of these criteria.

Objective

To assess whether Hungarian care units fulfil international criteria.

Methods

A self-report questionnaire was assembled based on international guidelines and sent to Hungarian care units focusing on 3 main aspects: personnel and instrumental background, disease-modifying therapy use, number of people living with multiple sclerosis receiving care in care units. Data on number of persons with multiple sclerosis were compared to Hungarian prevalence estimates. Descriptive statistics were used to analyse data.

Results

Out of 27 respondent care units, 3 fulfilled minimum requirements and 7 fulfilled minimum and recommended requirements. The least prevalent neighbouring specialties were spasticity and pain specialist, and neuro-ophthalmologist and oto-neurologist. Only 15 centres used all available disease modifying therapies. A total number of 7213 people with multiple sclerosis received care in 27 respondent centres. Compared to prevalence estimates, 2500 persons with multiple sclerosis did not receive multiple sclerosis specific care in Hungary.

Conclusion

Less than half of Hungarian care units provided sufficient care for people living with multiple sclerosis. Care units employing fewer neighbouring specialties, might have difficulties diagnosing and providing appropriate care for persons with multiple sclerosis, especially for people with progressive disease course, contributing to the reported low number of persons living with multiple sclerosis.

Prescription trends of disease-modifying treatments for multiple sclerosis in Iran over the past 30 years

BACKGROUND

Iran, as a middle income country, is one of the places with high and rising prevalence of multiple sclerosis (MS). Regarding the substantial economic burden, reviewing the trend in prescribed disease modifying treatments (DMTs) could be of help. Here we studied the DMT information of nearly 14000 MS cases and its trends change for 30 years to improve health services to patients.

METHODS

The population base of this descriptive-analytical (cross-sectional) study consisted of all MS patients in the nationwide MS registry of Iran (NMSRI), up to August 1, 2021. Registrars from 15 provinces, 24 cities, 13 hospitals,8 MS associations, 16 private offices, and 7 clinics had entered the data.

RESULTS

Overall, 14316 cases were enrolled. The majority (76.1%) were female. The youngest and eldest patients were 5 and 78 years old, respectively. Diagnosis delay was under one year in most cases (median: 0, IQR: 0 - 1). Most (61.4%) had RRMS. Generally, platform injectables (IFN beta, glatiramer acetate) were the most used DMTs until 2010. It seems that introduction of newer agents (antiCD20s and oral DMTs) resulted in a decrease in the use of former drugs since around 2015. Some unusual practices are prominent such as using not approved DMTs for PPMS over the years, or administering high efficacy drugs like natalizumab for CIS. The results indicate the remaining popularity of first line injectable DMTs in female and pediatric patients.

DISCUSSION

Mean age (SD) at onset in our study (29 ± 8.8) is near the statistics in Asia and Oceania (28 ± 0.7). Concerns about COVID-19 had a noticeable impact on administering high efficacy drugs like rituximab and fingolimod. However, in male patients this approach has not been the case. It may be related to more aggressive disease course in this group. The other possible explanation could be planning for pregnancy in female cases. The popularity of platform injectable drugs in pediatric MS may be related to its favorable safety profile over the years. Another point in this group, is the superiority of rituximab over other highly efficient medications.
