RESUMEN

OBJECTIVES: The objectives were to understand the employment impacts of myelin oligodendrocyte glycoprotein-associated antibody disease (MOGAD) on adults in an international cohort by determining lost employment, work hours, and wages. BACKGROUND: Clinically, MOGAD can be associated with significant disability; however, its socioeconomic consequences for adults are barely reported. METHODS: Participants of potential working age (18-70 years old) with neurologist-diagnosed MOGAD were recruited from clinical sites in 13 countries, April 2022 to August 2023. Each participant completed a one-time survey. Regression models assessed associations with post-MOGAD (1) unemployment and (2) work hours. RESULTS: A total of 117 participants (66.7% female), mean age 39.7 years, median disease duration 3 years (25th, 75th percentile: 1, 7) were analyzed. Employment post-MOGAD reduced from 74 (63.2%) to 57 (48.7%) participants. Participants employed pre-diagnosis reduced their work hours, on average, from 31.6 hours/week to 19.5 hours/week post-diagnosis. Residence in a high-income country was statistically significantly associated with post-diagnosis employment and higher weekly work hours. Depressed mood was associated with unemployment. MOGAD-related pain and history of myelitis were independently associated with lost work hours. CONCLUSION: MOGAD can have significant impacts on adult employment, particularly in non-high-income countries. Depressed mood and pain are potentially modifiable factors related to socioeconomic status in MOGAD.

RESUMEN

OBJECTIVE: This study aimed to evaluate the diagnostic accuracy of dried blood spot (DBS) compared with conventional serum Aquaporin-4-IgG (AQP4-IgG) testing. METHODS: Prospective multicenter diagnostic study was conducted between April 2018 and October 2023 across medical centers in the United States, Uganda, and the Republic of Guinea. Neuromyelitis optica spectrum disorder (NMOSD) patients and controls collected blood on filter paper cards along with concurrent serum samples. These samples underwent analysis using flow cytometric live-cell-based assays (CBA) and enzyme-linked immunosorbent assay (ELISA) to determine AQP4 serostatus. The accuracy of AQP4-IgG detection between DBS and serum (gold standard) was compared. RESULTS: Among 150 participants (47 cases, 103 controls), there was a strong correlation between DBS and serum samples (Spearman's correlation coefficient of 0.82). The AUC was 0.97 (95% CI: 0.92-0.99). AQP4-IgG detection through DBS showed 87.0% sensitivity (95% CI: 0.74-0.95) and 100% specificity (95% CI: 0.96-1.00) using CBA, and 65.2% sensitivity (95% CI: 0.43-0.84) and 95.2% specificity (95% CI: 0.76-0.99) using ELISA. Serum ELISA demonstrated 69.6% sensitivity (95% CI: 0.47-0.87) and 98.4% specificity (95% CI: 0.91-0.99). The stability of DBS in detecting AQP4-IgG persisted over 24 months for most cases. INTERPRETATION: The DBS represents a viable alternative for detecting AQP4-IgG in resource-limited settings to diagnose NMOSD, offering high sensitivity and specificity comparable to serum testing. Moreover, DBS has low shipping costs, is easy to administer, and is suitable for point-of-care testing.

RESUMEN

The differential diagnosis of multiple sclerosis can present specific challenges in patients from Latin America, Africa, the Middle East, eastern Europe, southeast Asia, and the Western Pacific. In these areas, environmental factors, genetic background, and access to medical care can differ substantially from those in North America and western Europe, where multiple sclerosis is most common. Furthermore, multiple sclerosis diagnostic criteria have been developed primarily using data from North America and western Europe. Although some diagnoses mistaken for multiple sclerosis are common regardless of location, a comprehensive approach to the differential diagnosis of multiple sclerosis in Latin America, Africa, the Middle East, eastern Europe, southeast Asia, and the Western Pacific regions requires special consideration of diseases that are prevalent in those locations. A collaborative effort has therefore assessed global differences in multiple sclerosis differential diagnoses and proposed recommendations for evaluating patients with suspected multiple sclerosis in regions beyond North America and western Europe.

RESUMEN

Obesity is a risk factor for developing and worsening multiple sclerosis (MS) and is often comorbid with MS, exacerbating disability. We retrospectively studied MS patients starting glucagon-like peptide-1 (GLP-1) agonists at the [redacted for review] U.S.A. (January 2005-June 2024). Patients (n = 49) were mostly female (73%), average age 54 years old, with relapsing disease (78%) and an average starting body mass index (BMI) of 39.7 kg/m2 (range 25.9, 58.9 kg/m2; n = 43 clinically obese or BMI > 30 kg/m2) and weight of 110.6 kg (245.6 lbs.; range 68-155.8 kg, 150-343.4 lbs.). The most commonly taken disease modifying therapy (DMT) was ocrelizumab (39%) while 24% of patients were not taking any DMT. The most common comorbidities were hypertension (59%), hyperlipidemia (55%), and diabetes mellitus (41%). Patients took GLP-1 agonists for an average of 24.2 months (median 21.4; range 3.2, 88.5 months). Patients lost on average 0.47 kg/month (1.03 lbs./month; range of total weight change: 27.7 kg (61.1 lbs.) lost, 7.7 kg (17.0 lbs.) gained). Among overweight and obese patients with MS, those with a higher starting BMI tended to lose more weight. 29% experienced side effects of the GLP-1 drugs with 3 discontinuations due to tolerability. Four patients accrued new demyelinating lesions on MRI (one on no DMT, two started on a high-efficacy DMT for the first time in the past 6 months, and one on a high-efficacy DMT) and one patient experienced a new MS attack (treated with interferon beta-1a). Our early experience suggests GLP-1 agonists are safe in MS patients, who have a similar tolerability to the general population on this medication class and measurable and sustained but somewhat less than anticipated weight loss.

RESUMEN

BACKGROUND: The clinical spectrum and diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) has evolved in the setting of an optimized anti-MOG-IgG cell-based assay and expert consensus. The McDonald criteria for MS have been revised multiple times to improve the accuracy and specificity of diagnosis on a framework based on clinical presentation, MRI findings, and CSF results. While the uses of MS and MOGAD diagnostic criteria are helpful for typical cases, such utility for patients with overlapping clinical, laboratorial, and imaging features is unknown, posing diagnostic and management uncertainties. OBJECTIVES: To report a multicenter cohort of patients with overlapping phenotypic features of MOGAD and MS and evaluate the application of new MOGAD diagnostic criteria. METHODS: A collaborative retrospective cohort study was performed to identify patients with both positive serum anti-MOG-IgG and fulfillment of the MS revised 2017 McDonald criteria. Clinical and radiographic features of patients fulfilling inclusion criteria were reviewed longitudinally, including relapses, repeated MRI, and MOG-IgG testing in detail to allow the panel of expert opinion to assign to each case. The International MOGAD Panel proposed criteria were applied at onset and last follow-up to each case and compared to the expert author diagnosis assignment based on presentation, clinical and imaging features, and response to treatment. RESULTS: Ten of 225 (4%) MOG-IgG seropositive cases met study inclusion criteria [seven of 10 were female; age at initial event: eight adults (mean age 26.8 years), two adolescents (mean age 14.5 years)]. AQP4-IgG was negative for all. Apart from serum titers of MOG-IgG, distinguishing clinical and radiographic features [i.e., clinical severity of the initial demyelinating event, radiographic features (optic nerve/spine/brain), and presence/absence of lesion normalization on serial scans] led to consensus of three separate classifications differing by degrees of shared features of MOGAD and MS. Patients were classified by expert panel into (1) Classic MOGAD even with MS-like, well-defined brain lesions, when severe events and most T2 lesions normalized (n = 5; MOG-IgG titers 1:100, 1:20, 1:160, 1:40, 1:200); (2) Classic RRMS included cases thought to have likely false positive or clinically irrelevant MOG-IgG, due to mild clinical events and no radiographic normalization of well-defined MS-like lesions (n = 3; MOG titers 1:20, 1:100, 1:40); (3) MOGAD and MS overlapping phenotype was defined by those with a combination of mild and severe clinical events, partial T2 lesion normalization, both well- and ill-defined lesions (n = 2; MOG titers 1:20, 1:100). The application of the International MOGAD Panel criteria categorized five patients (50%) in agreement with expert assignment. One additional patient was classified in agreement to assignment when MOGAD criteria were applied after serial MOG-IgG titers testing. DISCUSSION: While the International MOGAD Panel diagnostic criteria have helped with accuracy for the diagnosis of this condition, in a group of patients seropositive for MOG-IgG with overlapping clinical and imaging features of RRMS criteria review may lead to increased accuracy. Serial serologies, repeated imaging, close attention to clinical course, and response to therapy are possible variables to consider for further refinement of MOGAD diagnostic criteria.

RESUMEN

BACKGROUND & OBJECTIVE: In lower-middle income countries such as Bhutan, the treatment gap for epilepsy is over 50% as compared to a treatment gap of less than 10% in high-income countries. We aim to analyze the quality of epilepsy care for women of childbearing potential in Bhutan using the Quality Indicators in Epilepsy Treatment (QUIET) tool, and to assess the usefulness of the tool's section for women with active epilepsy (WWE) in the Bhutanese setting. METHODS: A prospective convenience cohort was enrolled in Thimphu, Paro, Punakha, and Wangdue, Kingdom of Bhutan, in 2022. Bhutanese women of childbearing potential at the time of enrollment (18-44 years old) were evaluated for the diagnosis of active epilepsy and underwent a structured survey-based interview with Bhutanese staff. Participants were surveyed on their epilepsy, pregnancy, and antiseizure medicine (ASM) histories. The clinical history and quality of epilepsy care of adult WWE were assessed using a section of the QUIET tool for women, an instrument originally developed by the U.S. Department of Veterans Affairs to analyze the quality of epilepsy care for American adults. RESULTS: There were 82 Bhutanese WWE of childbearing potential, with mean age of 30.6 years at enrollment (range 18-44, standard deviation (SD) 6.6) and mean age of 20.3 years at epilepsy diagnosis (range 3-40, SD 8.0)). 39 % (n = 32) had a high school or above level of education, and 42 % (n = 34) were employed. 35 % (n = 29) reported a seizure within the prior week, and 88 % (n = 72) reported a seizure within the prior year. 49 % (n = 40) of participants experienced > 100 lifetime seizures. All but one participant took antiseizure medications (ASMs). At enrollment, participants presently took no (n = 1), one (n = 3), two (n = 37), three (n = 25), four (n = 11), or over five (n = 5) ASMs. The most common ASMs taken were levetiracetam (n = 40), phenytoin (n = 27), carbamazepine (n = 23), phenobarbital (n = 22), and sodium valproate (n = 20). 61 % of all WWE took folic acid. Of the 40 previously pregnant WWE, eight (20 %) took folic acid during any time of their pregnancy. 35 % (n = 29) used betel nut (doma, quid) and 53 % (n = 21) of pregnant WWE used betel nut during pregnancy. CONCLUSIONS: Based on data about WWE participants' ASM, supplement, and substance use, our study identified the high use of first generation ASMs (including valproate), frequently in polytherapy, and betel nut use as treatment gaps in women of childbearing potential age with active epilepsy in Bhutan. To address these gaps for locations such as Bhutan, we propose modifications to the QUIET tool's "Chronic Epilepsy Care for Women" section.

RESUMEN

There are more than 100 million forcibly displaced persons (FDPs) in the world today, including a high number of people who experience neurologic symptoms and presentations. This review summarizes the conceptual frameworks for understanding neurological health risks and conditions across the migration journey (premigration, migration journey, and postmigration) and life span, including special attention to pediatric FDPs. The interaction with psychiatric illness is discussed, as well as the available published data on neurologic presentations in FDPs in the medical literature. A social determinant of health lens is used to provide ways in which forcible displacement can influence brain health and neurological outcomes. Priorities and future needs for the neurological care of refugees and other FDPs are suggested.

RESUMEN

Low-field, portable MRI (LF-MRI) promises to expand neuroimaging access for patients with multiple sclerosis (MS). We aimed to measure the feasibility and tolerability of LF-MRI for clinical use in 50 people with MS (mean age 46.5 ± 15.3 years; 72 % female; median disease duration 5.9 years), 38 % of whom reported barriers to undergoing MRI, and 34 % of whom were low-income or unemployed. Experience ratings of LF-MRI were strongly positive (mean rating of 9.2 on a ten-point scale). Seventy percent of participants were willing to receive future LF-MRI scans, and 46 % preferred LF-MRI to standard MRI (35 % undecided). The overall feasibility and tolerability of LF-MRI support its integration into a one-stop, patient-centered model of outpatient MS care.

RESUMEN

Nicolau syndrome is a rare, iatrogenic skin reaction after parental drug administration, characterized by severe pain at an injection site, followed by hemorrhage, ulceration, and often necrosis. We present a case of a patient on glatiramer acetate for many years (initially Copaxone then Glatopa) who developed Nicolau syndrome, the second reported case after generic glatiramer acetate. All reported cases of Nicolau syndrome after glatiramer acetate are reviewed. The case highlights the importance of prompt recognition of this skin reaction by neurologists and raises awareness of the risks of skin reactions even in low-risk injectable DMTs.

RESUMEN

Tumefactive multiple sclerosis (TMS) is characterized by large demyelinating brain lesions. This was a retrospective cohort study of 67 patients with TMS between January 2015-2023, examining different disease modifying therapy impact on expanded disability scale score change at follow-up. Median age was 36 with a female predominance. Mean EDSS was 3.3 ± 2.3 at TMS onset, 2.1 ± 1.9 at year one, and 2.1 ± 1.9 at last follow-up. A multilinear regression model found higher presentation EDSS and post-diagnosis non-B-cell high efficacy therapies were each independently associated with higher EDSS at last follow up. Further research is needed to determine the value of B-cell therapy in TMS.

RESUMEN

BACKGROUND AND OBJECTIVES: We aim to characterize the sociodemographic and clinical factors associated with loss of jobs, income, and work hours in people with neuromyelitis optica spectrum disorder (NMOSD) in the United States. METHODS: A REDCap-based survey was administered to working-age NMOSD patients (18-70 years old) querying demographic information, symptoms, immunosuppression, work hours, income, and caregiver work (11/2022-07/2023). Regression models were developed using MATLAB. RESULTS: Of 127 participants (97 female; 55% AQP4-antibody, 19% MOG antibody; 69% Caucasian, 7% Hispanic), with an average diagnosis age of 38.7 years, average disease duration of 6.4 years, mean 3.1 attacks, and 94% of whom were treated with immune system-directed therapy (53% rituximab, 8% satralizumab, 7% eculizumab, 6% mycophenolate mofetil, 4% inebilizumab, 2% azathioprine, 10% IVIg, 10% other), 56% lost a job due to NMOSD. Employment decreased 12% (80% pre- to 68% post-diagnosis). Thirty-six percent of participants said they no longer worked outside the home. Significant predictors for post-NMOSD diagnosis employment status included younger age, lower pain level, no walking aids, and having a job prediagnosis. Sixty-eight percent of those employed prediagnosis reduced their work hours, dropping an average of 18.4 h per month since being diagnosed (±10.1 h). Average annual income grew slowly at $1998 during the average 6.4 years of disease duration (14% of the value predicted by the U.S. Bureau of Labor Statistics). Sixty percent of participants had a regular unpaid caregiver; 34% of caregivers changed their work hours or job to help manage NMOSD. DISCUSSION: We provide a structured analysis of the impact of NMOSD on employment, work hours, and income in the United States, demonstrating its major effect on the livelihoods of patients and their caregivers.

RESUMEN

BACKGROUND: We previously reported more rapid accrual of ambulatory impairments in Black compared to White individuals with relapsing remitting multiple sclerosis (RRMS) and higher body mass index (BMI). Hypertension and lower neighborhood socioeconomic status (SES) were associated with greater impairment, irrespective of race. We hypothesize that these common social and health inequities may explain a substantial portion of the racial differences in ambulation in American individuals with RRMS. METHODS: Causal mediation analyses investigated baseline and change-over-time mediators of ambulatory impairment differences between 1795 Black and White individuals with RRMS using a retrospective cohort study comprised of electronic health record data from 8491 clinical encounters between 2008 and 2015 where Timed 25-Foot Walk (T25FW) speeds without assistive devices were recorded. The hypothesis was that BMI, neighborhood SES, and hypertension were possible mediators. RESULTS: At baseline, Black individuals with RRMS (n = 175) had significantly slower T25FW speeds (5.78 vs 5.27 ft/s), higher BMI, a higher prevalence of hypertension, and they were more likely to live in lower-income neighborhoods than White individuals (n = 1,620). At baseline, a significant proportion (33.7%; 95% CI, 18.9%-59.4%) of the T25FW difference between Black and White individuals was indirectly due to a higher BMI (12.5%), hypertension burden (9.5%), and living in lower-income neighborhoods (11.2%). Once baseline mediation relationships were accounted for, there were no significant longitudinal mediation relationships. CONCLUSIONS: The findings implicate social and health disparities as prominent drivers of ambulatory differences between Black and White individuals with RRMS, suggesting that wellness and health promotion are essential components of MS care, particularly for Black individuals.

RESUMEN

BACKGROUND AND OBJECTIVE: Of ~5 million people living with epilepsy (PLWE) in Sub-Saharan Africa, roughly one-third experience depression and over one third experience anxiety. In Guinea, these issues may be compounded by fewer available resources, such as appropriate anti-seizure medications (ASMs). We aim to quantify seizure frequency, anxiety and depression in PLWE in Guinea, before and after a free ASM intervention and neurologist's consultation. METHODS: Guinean participants >12 years old with ≥2 unprovoked seizure were prospectively recruited. As part of a broader interview, participants reported prior 30-day seizure frequency and screened for depression (PHQ-9) (range 0-27 points) and anxiety (GAD-7) (range 0-21 points) with re-evaluation at 90 days. RESULTS: Of 148 participants enrolled (mean age = 27.3 years, range 12-72; 45% female), 62% were currently taking ASMs. For the 30 days pre-enrolment, average seizure frequency was 3.2 (95%CI 2.3, 4.2); 28% of participants were seizure-free. ASM regimens were modified for 95% of participants, mostly initiating levetiracetam (n = 115, 80% of modifications). 90-day study retention was 76% (n = 113) among whom 87% reported full adherence to the ASM. After 90 days, the average seizure frequency over the prior 30 days was 1.5 (95%CI 0.5, 2.6), significantly lower than at baseline (p = 0.002). 66% were seizure-free. At baseline, average PHQ-9 score was 21.2 (95%CI [20.2, 22.2]), indicating severe depressive symptoms. Average GAD-7 score was 16.5 [15.6, 17.4], indicating severe anxious symptoms. At 90-days, average PHQ-9 score was 17.5[16.4, 18.5] and significantly lower than baseline (p < 0.001). Average GAD-7 score was 14.4 [13.6, 15.3] and significantly lower than baseline (p = 0.002). Seizure frequency was not correlated with PHQ-9 nor GAD-7 scores at baseline but was at 90 days for both PHQ-9 (r = 0.24, p = 0.01) and GAD-7 (r = 0.22, p = 0.02) scores. The prevalence of suicidal ideation dropped from 67% to 47% of participants (p = 0.004). DISCUSSION: ASM management has dual importance for PLWE in resource-limited settings, improving both seizure control and mental health.

RESUMEN

OBJECTIVE: Most people with epilepsy (PWE) could live seizure-free if treated with one or more antiseizure medications (ASMs). The World Health Organization (WHO) estimates that 75% of PWE in low-resource settings lack adequate antiseizure treatment. Limited education surrounding epilepsy and the out-of-pocket costs of ASMs in particular pose barriers to managing epilepsy in resource-poor, low-income settings. The aim of this study is to implement and test a novel strategy to improve outcomes across the epilepsy care cascade marked by (1) retention in epilepsy care, (2) adherence to ASMs, and (3) seizure reduction, with the measured goal of seizure freedom. METHODS: A randomized, double-blinded clinical trial will be performed, centered at the Ignace Deen Hospital in Conakry, Republic of Guinea, in Western Sub-Saharan Africa. Two hundred people with clinically diagnosed epilepsy, ages 18 years and above, will receive education on epilepsy and then be randomized to (i) free ASMs versus (ii) conditional cash, conditioned upon return to the epilepsy clinic. Participants will be followed for 360 days with study visits every 90 days following enrollment. SIGNIFICANCE: We design a randomized trial for PWE in Guinea, a low-resource setting with a high proportion of untreated PWE and a nearly completely privatized healthcare system. The trial includes a conditional cash transfer intervention, which has yet to be tested as a targeted means to improve outcomes for people with a chronic neurological disorder. The trial aims to provide an evidence base for the treatment of epilepsy in such settings. PLAIN LANGUAGE SUMMARY: We present a clinical trial protocol for a randomized, blinded study of 200 people with epilepsy in the low-resource African Republic of Guinea, providing an educational intervention (E), and then randomizing in a 1:1 allocation to either free antiseizure medication (m) or conditional cash (c2 ) for 360 days. Measured outcomes include (1) returning to outpatient epilepsy care, (2) adherence to antiseizure medications (ASMs), and (3) reducing the number of seizures. This study is an initial look at giving small amounts of cash for desired results (or "nudges") for improving epilepsy outcomes in the sub-Saharan African and brain disorder contexts.

RESUMEN

OBJECTIVE: To explore the social determinants of health (SDOH) in people with multiple sclerosis (MS) with SDOH, elucidating the SDOH variables of highest salience in this geographical region. METHODS: Focus groups and a structured survey of Massachusetts residents with SDOH and a diagnosis of MS were conducted by a neurologist and staff, December 2022-July 2023, via Zoom™. Twenty-one consecutively-recruited, convenience-sampled adults participated in four groups. A thematic inductive approach was taken. RESULTS: Participants (average age 45 years old; average time since MS diagnosis 13.7 years; 14 cisgender female, 1 transgender female, 5 cisgender male, 1 non-binary; 33 % white, 57 % black, 5 % Asian, 5 % other; 18 % Hispanic/Latinx; modal response of 5 SDOH) identified the following key SDOH: (1) race and ethnicity, related to (a) diagnostic delays in MS, (b) limited familiarity with MS and its etiology, and (c) value of ongoing MS care; (2) gender, focused on limited published data in African American men and transgender people; (3) social and community contexts; and (4) financial burdens, related to (a) out-of-pocket costs of MS disease modifying therapies, (b) lost work time, and (c) transportation. Lower frequency SDOH variables were access to public toilets, lost job promotions, environmental exposures, and concern about discrimination. Unmet needs emphasized (1) public understanding of MS; (2) financial support for DMT costs, closer access to infusion centers, and culturally competent care; (3) support for research participation; (4) reliable transportation; and (5) patient awareness of extant services and support programs. CONCLUSIONS: This in-depth assessment of people with MS who possess multiple SDOH identified the most salient and commonly experienced SDOH, common themes related to the SDOH in MS, unmet needs, and future opportunities.

RESUMEN

BACKGROUND: This study assesses perceptions of quality of life (QOL) and overall health in people with epilepsy (PWE) in Guinea after a clinical intervention providing modified and new antiseizure medicine (ASM) regimens. METHODS: Participants 12 years and older diagnosed with active epilepsy were prospectively and consecutively enrolled at two health centers in the Republic of Guinea (one urban, one rural) in 2022. 95% of participants were prescribed new/increased ASM doses, and interviewed for QOL and overall health perceptions at enrollment and three- and six-month follow ups. Univariate and linear mixed models were used to evaluate effects on QOL and overall health over time. RESULTS: The mean QOLIE-31 score (±SD) among 148 Guinean PWE (82 male, 66 female; mean age 27.3; 137 with >1 seizure in prior year) was 51.7 ± 12.8 at enrollment, 57.6 ± 16.0 after three months (n = 116), and 52.2 ± 9.9 after six months (n = 87). Overall health scores were 53.1 ± 26.9, 72.6 ± 21.5, and 65.7 ± 20.2 respectively. After three months, PWE had improved overall health and QOLIE-31 scores (p<0.0001, p = 0.003), but these improvements persisted for overall health and not QOLIE-31 after six months (p = 0.001, p = 0.63). Seizure freedom (prior 30 days) was 26% initially, and 62 (42%) of the remaining PWE experiencing seizures achieved seizure freedom at either the first or second follow-ups. CONCLUSIONS: A noticeable discrepancy exists between Guinean PWE's self-rated perceptions of QOL and overall health. Purely clinical interventions may not be sufficient to improve QOL, especially in people that experience severe, previously-untreated epilepsy in lower income settings.

RESUMEN

BACKGROUND AND PURPOSE: Serum levels of neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) are promising neuro-axonal damage and astrocytic activation biomarkers. Susac syndrome (SS) is an increasingly recognized neurological condition and biomarkers that can help assess and monitor disease evolution are highly needed for the adequate management of these patients. sNfL and sGFAP levels were evaluated in patients with SS and their clinical relevance in the relapse and remission phase of the disease was assessed. METHODS: As part of a multicentre study that enrolled patients diagnosed with SS from six international centres, sNfL and sGFAP levels were assessed in 22 SS patients (nine during a relapse and 13 in remission) and 59 age- and sex-matched healthy controls using SimoaTM assay Neurology 2-Plex B Kit. RESULTS: Serum NfL levels were higher than those of healthy controls (p < 0.001) in SS patients and in both subgroups of patients in relapse and in remission (p < 0.001 for both), with significantly higher levels in relapse than in remission (p = 0.008). sNfL levels showed a negative correlation with time from the last relapse (r = -0.663; p = 0.001). sGFAP levels were slightly higher in the whole group of patients than in healthy controls (p = 0.046) and were more pronounced in relapse than in remission (p = 0.013). CONCLUSION: In SS patients, both sNFL and sGFAP levels increased compared with healthy controls. Both biomarkers had higher levels during clinical relapse and much lower levels in remission. sNFL was shown to be time sensitive to clinical changes and can be useful to monitor neuro-axonal damage in SS.

RESUMEN

The standard of care for patients with neuromyelitis optica (NMO) has become highly unequal globally. Sufficient data have been published to demonstrate that NMO is a disabling-and at times, fatal-disease needing preventive immunosuppressive treatment. Since 2019, there are multiple regulatory authority-approved disease-modifying therapies (DMTs) for aquaporin-4 antibody seropositive NMO for patients. Reframing the picture of NMO globally is now needed. When considered as a disease of high mortality when left untreated, parallel programs to those for cancer, HIV/AIDS, or tuberculosis can be considered. Nine collective goals for rectifying global inequities in NMO diagnosis and treatment are proposed.

RESUMEN

BACKGROUND: Familial Mediterranean Fever (FMF) is associated with increased risk of multiple sclerosis (MS). Optimal treatment of patients with comorbid FMF and MS remains uncertain. CASE: A 28-year-old woman with FMF, treated with colchicine, had symptomatic onset of relapsing remitting MS following four simultaneous vaccines. MRI brain with a 7-Tesla magnet demonstrated several areas of leptomeningeal enhancement with predominant linear, spread/fill and rare nodular patterns. Central vein signs were present in supratentorial white matter lesions. She received four cycles of ocrelizumab and achieved no evidence of disease activity (NEDA-3) at 20 months' follow up. DISCUSSION: FMF with incident CNS demyelinating disease demonstrated neuroimaging features typical for classic RRMS including the central vein sign and leptomeningeal enhancement. Treatment with B-cell depleting therapy for FMF-MS led to clinical stability and symptomatic improvement at 20 months' follow up. We add to the sparse literature characterizing the course of FMF as a genetic risk factor for CNS demyelinating disease, demonstrating pathognomonic imaging features of MS on 7 T imaging and treatment efficacy with B-cell depletion.

RESUMEN

Neuromyelitis optica spectrum disorder (NMOSD) is a rare and disabling neurological disorder, marked by recurrent attacks of the central nervous system. NMO has a high female predominance and disproportionately affects racial and ethnic groups who are under- and unemployed in the USA. Three focus groups, involving 20 working age adults with NMOSD in the USA, were convened via Zoom online, to discuss the topic of employment in NMOSD. Consolidated Criteria for Reporting Qualitative research (COREQ) were followed. Discussions were coded for major themes using an inductive approach. The following themes emerged: (1) Barriers due to NMOSD on employment including (i) visible and invisible symptoms, (ii) the burden of treatment, and (iii) time to diagnosis; (2) Mitigating factors when NMOSD affects employment; (3) Impact of COVID-19; (4) Impact on income; (5) Impact on new and future employment and higher education opportunities; and (6) Unmet needs that are pragmatically addressable, outside of major policy or scientific changes.
