RESUMO
BACKGROUND: Patients with MS and related disorders (pwMSARD) on B-cell depleting treatments have attenuated immune responses to vaccination and were eligible to receive tixagevimab/cilgavimab. OBJECTIVES: Understand incidence and severity of COVID-19 in pwMSARD on B-cell depleting therapies who received tixagevimab/cilgavimab compared to an untreated group. METHODS: We conducted a retrospective medical records review of adult pwMSARD on B-cell depleting treatments who received tixagevimab/cilgavimab between 1/2022-1/2023. PwMSARD on B-cell depleting treatments who did not served as a control group (CG). We compared COVID-19 incidence and severity within 6 months of tixagevimab/cilgavimab or rituximab/ocrelizumab infusion for the CG. RESULTS: 210 patients were identified, 135 in the treatment group (TG) and 75 in the CG. In the TG, 24 (17.8 %) developed COVID-19 compared to 12 (16 %) in the CG. There was no difference in the odds of developing COVID-19 in an unadjusted logistic regression model (OR=1.14; 95 % CI: 0.53, 2.42; p = 0.74) or after adjusting for age and disease duration (OR=1.05; 95 % CI: 0.47, 2.37; p = 0.91). There was also no difference in COVID-19 severity between groups. CONCLUSIONS: There was no difference in COVID-19 infection rates or severity in pwMSARD on B-cell depleting treatments who received tixagevimab/cilgavimab compared to those who remained untreated.

Purpose of Review: Lack of consistent data and guidance have led to variations between clinicians in the management of pregnancy in women with multiple sclerosis (MS). Pregnant and/or lactating women are often excluded from clinical trials conducted in MS, and thus, the labeling for most disease-modifying therapies (DMTs) excludes use during pregnancy. This has led to heterogeneity in interpretation and labeling regarding the safety of DMTs during pregnancy and lactation and the required preconception washout periods. This review identifies key themes where there is conflicting information surrounding family planning and pregnancy in MS, focusing on the most common discussion points between physicians and patients during preconception planning, pregnancy, postpartum, and lactation. The goal was to inform the patient-physician conversation and provide best practice recommendations based on expert clinical expertise and experience. Recent Findings: We outline the latest evidence-based data for DMT use during pregnancy and lactation, the effect of MS on fertility and fertility treatments, the risk of adverse pregnancy and delivery outcomes, the risk of postpartum relapse, and immunization and clinical imaging safety during pregnancy and breastfeeding. Summary: Management of family planning and pregnancy in patients with MS requires the most current information. Health care providers should discuss family planning early and frequently with patients with MS, and partners where practicable. Because management of pregnant people with MS will often require a risk/benefit analysis of their needs, shared decision-making in family planning discussions is emphasized. Additional data are needed for specific and underrepresented populations with MS (e.g., single parents or those from the LGBTQ+ community) and those at risk of racial and socioeconomic disparities in care. Pregnancy registries and the design and conduct of clinical trials focused on pregnant and lactating patients should provide additional data to guide the ongoing management of patients with MS.
RESUMO
PURPOSE OF REVIEW: Multiple sclerosis (MS) is a chronic immune-mediated, inflammatory, neuro-degenerative disease of the central nervous system, prevalent in women of reproductive age. Today, many women want to start a family after MS diagnosis. There are over 20 treatments for MS, and safely navigating family planning is important. We review updated information on family planning, preconception, and peri-partum considerations, and reproductive concerns in special populations with MS. RECENT FINDINGS: There are no MS-related restrictions on any available and appropriate contraceptive method in women with MS. The question of MS and pregnancy outcomes following assisted reproduction, remains somewhat unsettled. In many studies, no elevated relapse risk is confirmed regardless of the type of fertility treatment. MRI status may offer better assessment of postpartum disease stability than relapse rate alone. Ongoing effective MS treatments during fertility assistance and before pregnancy, can further reduce the relapse risk. B-cell depleting therapies are emerging as safe and effective treatments for peripartum MS patients. SUMMARY: Patients with MS should receive accurate support and counseling related to their reproductive options. The general outlook on pregnancy and MS remains positive. The ever-increasing therapeutic complexity of MS calls for ongoing education and updated guidance for neuroimmunology and obstetrics healthcare providers.

BACKGROUND: Current guidance on the selection of appropriate contraception for people with multiple sclerosis (PwMS) is lacking. OBJECTIVE: To address this gap, an expert-led consensus program developed recommendations to support clinicians in discussing family planning and contraception with women and men with multiple sclerosis (MS). METHODS: A multidisciplinary steering committee (SC) of 13 international clinical experts led the program, supported by an extended faculty of 32 experts representing 18 countries. A modified Delphi methodology was used for decision-making and consensus-building. The SC drafted 15 clinical questions focused on patient-centered care, selection of contraception, and timing of stopping/starting contraception and disease-modifying therapies (DMTs). Statements addressing each question were drafted based on evaluation of published evidence and the experts' clinical experience. Consensus was reached if ⩾75% of respondents agreed (scoring 7-9 on a 9-point scale) with each recommendation. RESULTS: Consensus was reached on 24 of 25 proposed recommendations, including how and when to discuss contraception, types and safety of contraceptives, and how to evaluate the most appropriate contraceptive options for specific patient groups, including those with significant disability or being treated with DMTs. CONCLUSION: These expert recommendations provide the first practical, relevant, and comprehensive guidance for clinicians on the selection of contraception in PwMS.

Background: Multiple sclerosis (MS) is threefold more prevalent in women than men. However, sex-specific efficacy analysis for MS disease-modifying therapies is not typically performed. Methods: Post hoc analyses of data from female patients enrolled in the phase 3, double-blind OPTIMUM study of relapsing MS were carried out. Eligible adults were randomized to ponesimod 20 mg or teriflunomide 14 mg once daily for up to 108 weeks. The primary endpoint was annualized relapse rate (ARR); secondary endpoints included change in symptom domain of Fatigue Symptom and Impact Questionnaire-Relapsing Multiple Sclerosis (FSIQ-RMS) at week 108, number of combined unique active lesions (CUALs) per year on magnetic resonance imaging, and time to 12- and 24-week confirmed disability accumulation (CDA). Results: A total of 735 female patients (581 of childbearing potential) were randomized to ponesimod (n = 363, 49.4%) or teriflunomide (n = 372, 50.6%). Relative risk reduction in the ARR for ponesimod versus teriflunomide was 33.1% (mean, 0.192 vs. 0.286, respectively; p < 0.002). Mean difference in FSIQ-RMS for ponesimod versus teriflunomide was -4.34 (0.12 vs. 4.46; p = 0.002); rate ratio in CUALs per year, 0.601 (1.45 vs. 2.41; p < 0.0001), and hazard ratio for time to 12- and 24-week CDA risk estimates, 0.83 (10.7% vs. 12.9%; p = 0.38) and 0.91 (8.8% vs. 9.7%; p = 0.69), respectively. Incidence of treatment-emergent adverse events was similar between treatment groups (89.0% and 90.1%). Conclusions: Analyses demonstrate the efficacy and safety of ponesimod, versus active comparator, for women with relapsing MS, supporting data-informed decision-making for women with MS. Clinical Trial Registration Number: NCT02425644.

BACKGROUND AND OBJECTIVES: Racial disparities exist in both neurologic and obstetric populations, underscoring the importance of evaluating pregnancy outcomes in diverse women with multiple sclerosis (MS). The objective of this multicenter retrospective study was to compare pregnancy care and outcomes between Black and Hispanic (underrepresented) and White women with MS. METHODS: Demographic and clinical data were extracted from medical records of 9 US MS centers for women with MS/clinically isolated syndrome who delivered live births between 2010 and 2021. Sites identified at last 15 consecutive Black/Hispanic women and a matching number of White women. Socioeconomic factors, pregnancy, and MS care/outcomes were compared between groups (underrepresented and White and then Black and Hispanic) using Wilcoxon rank sum (U statistic and effect size r reported), χ2, t tests and logistic regressions as appropriate to data type. Multiple imputation by chained equation was used to account for missing data. RESULTS: Overall, 294 pregnancies resulting in live births were analyzed ( 81 Black, 67 Hispanic, and 146 White mothers). Relative to underrepresented women, White women lived in areas of higher median (interquartile range [IQR]) Child Opportunity Index (79 [45.8] vs 22 [45.8], U = 3,824, r = 0.56, p < 0.0001) and were more often employed (84.9% vs 75%, odds ratio [OR] 2.57, CI 1.46-4.50, p = 0.0008) and privately insured (93.8% vs 56.8%, OR 11.6, CI 5.5-24.5, p < 0.0001) and more received a 14-week ultrasound (98.6% vs 93.9%, OR 4.66, CI 0.99-21.96, p = 0.027). Mode of delivery was significantly different between the three groups (X2(10,294) = 20.38, p = 0.03); notably, Black women had the highest rates of emergency cesarean deliveries, and Hispanic women highest rates of uncomplicated vaginal deliveries. Babies born to underrepresented women had lower median (IQR) birthweights than babies born to White women (3,198 g [435.3 g] vs 3,275 g [412.5 g], U = 9,255, r = 0.12, p = 0.04) and shorter median (IQR) breastfeeding duration (4.5 [3.3] vs 6.0 [4.2] months, U = 8,184, r = 0.21, p = 0.003). While underrepresented women were younger than White women (mean [SD] 30.9 [4.8] vs 33.8 [4.0], t = 1.97, CI 1.96-3.98, p < 0.0001), their median (Q1-Q3, IQR) Expanded Disability Status Scale was higher (1.5 [1-2.5, 1.5] vs 1 [0-1.5, 1.5], U = 7,260, r = 0.29, p < 0.0001) before pregnancy. Finally, medical records were missing more key data for Black women (19.7% missing vs 8.9% missing, OR 2.54, CI 1.25-5.06, p = 0.008). DISCUSSION: In this geographically diverse multicenter cohort, underrepresented women entered pregnancy with higher disability and fewer health care resources. Pregnancy represents a pivotal window where structural factors affect maternal and fetal health and neurologic trajectories; it is a critical period to optimize care and health outcomes.

BACKGROUND: Dimethyl fumarate (DMF) has a favorable benefit-risk profile treating people with multiple sclerosis and should be used in pregnant women only if the potential benefits outweigh potential risks to the fetus. OBJECTIVE: Assess pregnancy outcomes in a completed international registry (TecGistry) of women with MS exposed to DMF. METHODS: TecGistry included pregnant women with MS exposed to DMF, with data collected at enrollment, 6-7 months gestation, 4 weeks after estimated due date, and at postpartum weeks 4, 12, and 52. Outcomes included live births, gestational size, pregnancy loss, ectopic/molar pregnancies, birth defects, and infant/maternal death. RESULTS: Of 397 enrolled, median (range) age was 32 years (19-43). Median (range) gestational week at enrollment was 10 (0-39) and at first DMF exposure was 1 (0-13). Median (range) duration of gestational DMF exposure was 5 weeks (0-40). Fifteen (3.8%) spontaneous abortions occurred. Of 360 (89.1%) live births, 323 were full term and 37 were premature. One neonatal death and no maternal deaths occurred. Adjudicator-confirmed EUROCAT birth defects were found in 2.2%. CONCLUSION: DMF exposure during pregnancy did not adversely affect pregnancy outcomes; birth defects, preterm birth, and spontaneous abortion were in line with rates from the general population.

BACKGROUND: Ocrelizumab is a commonly used anti-CD20 monoclonal antibody with efficacy in the treatment of both relapsing-remitting (RRMS) and primary progressive (PPMS) multiple sclerosis. Real world use of ocrelizumab in MS patients with higher levels of motor disability requiring a walker or a wheelchair is not well characterized as these populations were excluded from initial studies. Higher levels of disability may be a barrier to treatment access. This study aimed to describe the access to, and tolerability and therapeutic outcomes of ocrelizumab in highly disabled MS patients in a real-world setting. METHODS: As part of an ongoing study of ocrelizumab treatment access, barriers, and outcomes in MS patients at the Brigham MS Center, we retrospectively reviewed all patients with an Expanded Disability Status Scale (EDSS) of 6.5 or greater at the time of ocrelizumab initiation. All patients were started on ocrelizumab by their treating providers prior to this study initiation. Patients were excluded for recent rituximab exposure, co-treatment with more than one immunosuppressant, or alternative diagnoses contributing to high EDSS. Data was collected on incidence and severity of side effects while on ocrelizumab, persistence of treatment beyond one year, and MS stabilization versus progression while on this treatment. RESULTS: Of the 1219 patients on ocrelizumab between 2017 and 2021, 113 (9.3 %) had EDSS of 6.5 or greater at the time of ocrelizumab initiation. Of the 113, 51 (45.1 %) were excluded: 6 (5.3 %) because they were duplicates or didn't receive ocrelizumab at our center, 25 (22.1 %) due to rituximab treatment in the previous year, 16 (14.2 %) due to lack of at least 1 year of follow up, and 4 (3.5 %) due to relevant comorbidities/treatment with other immunosuppressants. 62 patients were included in the final analysis. At ocrelizumab start, mean age was 62.1 +/- 8.7 years and median EDSS was 7.0 (range 6.5 to 9.5). Ocrelizumab was started in 26 of the included 62 patients (41.9 %) because of objective clinical disease worsening, in 17 (27.4 %) because of subjective worsening, in 8 (12.9 %) to prevent future progression. 32 patients (51.6 %) continued ocrelizumab throughout the study period, with average length of ocrelizumab use of 36.5 +/- 17.0 months. 29 patients (46.8 %) experienced no side effects during the study period. 29 (46.7 %) patients discontinued treatment, and of those, 9 (31.0 %) cited more than one reason for discontinuation: 17 (58.6 %) cited side effects, 12 (41.4 %) cited progression/lack of benefit, 6 (20.7 %) cited the Covid19 pandemic, and 1 (3.4 %) cited financial issues as a reason for discontinuation. Over the course of the study, 16 (25.8 %) patients had disability worsening by EDSS, 5 (8.1 %) had disability improvement, and 41 (66.1 %) remained stable, with a median end EDSS of 7.0 (range 6.5 to 9.5). Importantly, 18 patients (29.0 %) reported subjective disease stability while on ocrelizumab. CONCLUSIONS: Ocrelizumab may lead to disease stabilization in a subset of highly disabled MS patients, but possible benefits need to be carefully balanced against the incidence of adverse events in this high-risk patient population.

Background: There is limited knowledge about T cell responses in patients with multiple sclerosis (MS) after 3 doses of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine. Objectives: Assess the SARS-CoV-2 spike antibody and T cell responses in MS patients and healthy controls (HCs) after 2 doses (2-vax) and 3 doses (3-vax) of SARS-CoV-2 mRNA vaccination. Methods: We studied seroconversion rates and T cell responses by flow cytometry in HC and MS patients on fingolimod or ocrelizumab. Results: After 2-vax, 8/33 (24.2%) patients in ocrelizumab group, 5/7 (71.4%) in fingolimod group, and 29/29 (100%) in HC group (P = 5.7 × 10-11) seroconverted. After 3-vax, 9/22 (40.9%) patients in ocrelizumab group, 19/21 (90.5%) in fingolimod group, and 7/7 (100%) in HC group seroconverted (P = 0.0003). The percentage of SARS-CoV-2 peptide reactive total CD4+ T cells increased in HC and ocrelizumab group but not in fingolimod group after 2-vax and 3-vax (P < 0.0001). The percentage of IFNγ and TNFα producing total CD4+ and CD8+ T cells increased in fingolimod group as compared to HC and ocrelizumab group after 2-vax and 3-vax (P < 0.0001). Conclusions: MS patients on ocrelizumab and fingolimod had attenuated humoral responses, but preserved cytokine producing T cell responses compared to HCs after SARS-CoV-2 mRNA vaccination. Clinical Trials Registration: NCT05060354.
RESUMO
BACKGROUND AND OBJECTIVES: Patients with multiple sclerosis (MS) may seek fertility treatment (FT)-including in vitro fertilization (IVF). Variable relapse risk after IVF has been reported in small historical cohorts, with more recent studies suggesting no change in annualized relapse rate (ARR). The objective of this study was to evaluate ARR 12 months pre-FT and 3 months post-FT in a multicenter cohort and identify factors associated with an increased risk of relapse. METHODS: Patients with clinically isolated syndrome (CIS) or MS aged 18-45 years with at least 1 FT from January 1, 2010, to October 14, 2021, were retrospectively identified at 4 large academic MS centers. The exposed period of 3 months after FT was compared with the unexposed period of 12 months before FT. FTs included controlled ovarian stimulation followed by fresh embryo transfer (COS-ET), COS alone, embryo transfer (ET) alone, and oral ovulation induction (OI). The Wilcoxon signed rank test and mixed Poisson regression models with random effects were used to compare ARR pre-FT vs post-FT, with the incidence rate ratio (IRR) and 95% CI reported. RESULTS: One hundred twenty-four FT cycles among 65 patients with MS (n = 56) or CIS (n = 9) were included: 61 COS-ET, 19 COS alone, 30 ET alone, and 14 OI. The mean age at FT was 36.5 ± 3.8 years, and the mean disease duration was 8.2 ± 5.0 years. Across 80 cycles with COS, only 5 relapses occurred among 4 unique patients within 3 months of treatment. The mean ARR after COS and before was not different (0.26 vs 0.25, p = 0.37), and the IRR was 0.95 (95% CI: 0.52-1.76, p = 0.88). No cycles with therapeutic disease-modifying therapies (DMTs) during COS had 3 months relapse (ARR 0 post-COS vs 0.18 pre-COS, p = 0.02, n = 34). Relapse rates did not vary by COS protocol. Among COS-ET cycles that achieved pregnancy (n = 43), ARR decreased from 0.26 to 0.09 (p = 0.04) within the first trimester of pregnancy. There were no relapses 3 months after ET alone and 1 relapse after OI. DISCUSSION: In this modern multicenter cohort of patients with MS undergoing diverse FTs, which included 43% on DMTs, we did not observe an elevated relapse risk after FT.

Multiple sclerosis is often diagnosed in patients who are planning on having children. Although multiple sclerosis does not negatively influence most pregnancy outcomes, less is known regarding the effects of fetal exposure to novel disease-modifying therapies (DMTs). The withdrawal of some DMTs during pregnancy can modify the natural history of multiple sclerosis, resulting in a substantial risk of pregnancy-related relapse and disability. Drug labels are typically restrictive and favour fetal safety over maternal safety. Emerging data reporting outcomes in neonates exposed to DMTs in utero and through breastfeeding will allow for more careful and individualised treatment decisions. This emerging research is particularly important to guide decision making in women with high disease activity or who are treated with DMTs associated with risk of discontinuation rebound. As increasing data are generated in this field, periodic updates will be required to provide the most up to date guidance on how best to achieve multiple sclerosis stability during pregnancy and post partum, balanced with fetal and newborn safety.

BACKGROUND: Sexual and physical violence against disabled individuals is widespread and linked to negative public health and social outcomes. The real-world prevalence of abuse in women with multiple sclerosis (MS) has not been well studied. OBJECTIVES: To explore abuse prevalence in a real-world cohort of females with MS attending an academic MS Center. METHODS: Prospective and retrospective abuse data were confidentially collected during neurology clinic visits and extracted from medical records for women attending an academic MS Center. Self-reported and provider-documented prevalence of abuse experiences were correlated with socio-economic and disease-specific factors. RESULTS: In total, 200 women completed prospective questionnaires, and 121 non-overlapping independent health records were retrospectively reviewed. Mean age (SD) was 49.055 (11.39). Seventy-six (38%) reported lifetime abuse incidents; 15% were abused within the previous year. Intimate partners were the most likely verbal (p ⩽ 0.01)) and physical (p = 0.04) abuse perpetrators. Neurologic disability correlated with greater likelihood of verbal abuse (p = 0.021) in prospective cohort. There was no billing or encounter documentation for any form of abuse. CONCLUSION: Intimate partner violence is common in women with MS, correlates with neurologic disability, and is underreported by the health system. Future research needs to focus on abuse detection and mitigation strategies.

BACKGROUND: Patients with multiple sclerosis (MS) on some disease modifying therapies (DMTs), particularly anti-CD20 and sphingosine-1-phosphate (S1P) modulators, are at increased risk of severe Coronavirus Disease 19 (COVID-19) and death. COVID-19 vaccinations are effective in preventing infection and severe disease, but humoral response to vaccination and outcomes of COVID-19 infection after vaccination in MS patients on DMTs remain less understood. METHODS: In this retrospective single-center study, patients enrolled in the CLIMB (Comprehensive Longitudinal Investigation of Multiple Sclerosis at Brigham and Women's Hospital) study and biorepository who had been vaccinated against COVID-19 and had SARS-CoV-2 spike antibody (anti-SARS-CoV-2 S Roche-Elecsys) testing were identified and compared to healthy controls. Demographic data, serum immune profiles including lymphocyte count, B-cell count, and immunoglobulins, and clinical outcome of COVID-19 infection were collected. RESULTS: 254 patients (73.2% female, mean (SD) age 52.9 (11.2) years) were identified. When controlling for age, time since vaccination, and vaccine type, patients on fingolimod, ocrelizumab, rituximab, mycophenolate mofetil, natalizumab and teriflunomide had significantly lower levels of spike antibodies compared to healthy controls (n = 34). Longer duration of treatment was associated with lower spike antibody levels in patients on anti-CD20 therapy (p = 0.016) and S1P modulators (p = 0.016) compared to healthy controls. In patients on anti-CD20 therapy, higher spike antibody levels were associated with higher CD20 cell count (p<0.001), and longer time since last anti-CD20 therapy infusion (p<0.001). 92.8% (13/14) vaccine responders (spike antibody titer >100 ug/dL) on anti-CD20 therapy demonstrated B-cell reconstitution (mean CD20 3.6%). Only 1 out of 86 patients with CD20 of 0% had a measurable spike antibody response to vaccination. During follow-up (mean 270 days), five patients were diagnosed with COVID-19 after vaccination (incidence 1.9%), all of whom had spike antibody < 20 ug/dL. No patients required ICU care or died. CONCLUSIONS: Patients on some DMTs demonstrate reduced humoral immunity after Sars-CoV-2 vaccination. Longer duration of anti-CD20 therapy and reduced CD20 cell count is associated with blunted humoral response to vaccination. CD20 reconstitution >0.1% appears necessary, but not always sufficient, for humoral response to vaccination. Breakthrough COVID-19 infection in our cohort of MS patients on DMT was higher than in population studies. We propose that adjustment of B-cell therapy administration to allow for B-cell reconstitution prior to vaccination should be considered.

BACKGROUND: Neurologic outcomes in patients with multiple sclerosis (MS) and related disorders (MSRD) following COVID-19 is not well understood. The objective of this study was to investigate neurologic outcomes in patients with MSRD post-COVID-19. METHODS: This was a retrospective medical records review study of adult patients with MSRD and COVID-19 infection at the Brigham MS Center. Neurologic worsening post-COVID-19 was defined as having a relapse, pseudorelapse, new brain MRI activity, worsening of preexisting MSRD symptoms, or development of other long-term neurologic symptoms. RESULTS: 111 patients, 85 (76.6%) females, with a mean [SD] age of 49.3 [12.2] years and median [range] EDSS of 2.5 [0, 8.5] were identified. 41 patients (36.9%) had neurologic worsening post-COVID-19. Of those, 19 (46.3%) had pseudorelapses, 2 (4.8%) had relapses, and 24 (58.5%) patients reported worsening of preexisting MSRD symptoms, or other new long-term neurologic symptoms. Neurologic worsening was associated with hospitalized (moderate or severe) COVID-19 (p = 0.001), treatment for COVID-19 (p = 0.006), and incomplete COVID-19 recovery (p = 0.0267) but not with age, sex, MS type, race, disease duration, EDSS, vitamin D use, or disease modifying therapy use. CONCLUSIONS: COVID-19 severity and lack of complete systemic recovery were associated with new or worsening neurologic symptoms in 36.9% of MSRD patients.

Background: The effects of pregnancy on multiple sclerosis (MS) inflammatory activity are not well described in women with moderate to severe disabilities. Objective: To quantify the peripartum annualized relapse rate (ARR) in women with MS with an Expanded Disability Status Scale (EDSS) ≥ 3. Methods: We performed a retrospective cohort study of 85 pregnancies in 74 subjects with preconception EDSS ≥ 3. We quantified peripartum ARR and tested for risk factors predictive of peripartum relapses, postpartum brain magnetic resonance imaging activity (new T2 or gadolinium-enhancing lesions), and disability worsening. Results: There were 74 live births, with a 56% operative delivery rate. In subjects with relapsing-remitting MS, ARR decreased to 0.11 during the third trimester of pregnancy compared to 0.59 in the year preconception and increased to 1.22 in the 3 months postpartum. Women with a higher preconception EDSS had higher odds of postpartum relapses and clinically significant worsening of disability as compared to subjects with a lower EDSS. Conclusions: Moderately to severely disabled women with MS have a lower risk of relapse during pregnancy as compared to preconception, followed by a marked increase postpartum. Further studies are needed to identify ways to reduce peripartum inflammatory activity and disability progression in women with MS with moderate to severe disability.
RESUMO
BACKGROUND: Peginterferon beta-1a is an interferon beta-1a formulation that has been pegylated, resulting in a longer half-life than other interferon beta formulations. We examined concentrations of peginterferon beta-1a in breast milk of lactating patients with multiple sclerosis (MS) receiving peginterferon beta-1a as their postpartum disease-modifying therapy. METHODS: After completion of titration to a full dose of peginterferon beta-1a and following a single full dose peginterferon beta-1a injection (125 µg), breast milk samples (≥10 mL) were collected by 5 women on days 1-14 post injection. Peginterferon beta-1a concentrations in breast milk samples were measured by a qualified enzyme-linked immunosorbent assay (detection threshold: 15 pg/mL). Mean and median daily concentrations and median maximum concentration (Cmax), time of Cmax (Tmax), time of last measurable concentration (Tlast), area under the concentration-time curve (AUClast), and relative infant dose (RID) were determined. RESULTS: After receiving a single full dose peginterferon beta-1a injection, the maximum breast milk concentration recorded in an individual patient was 126.2 pg/mL (0.00013 µg/mL) on day 6. The remaining patients all had maximum breast milk concentrations <72 pg/mL. The geometric mean of Cmax was 48.9 pg/mL and the median Tmax and Tlast were 4 and 7 days, respectively. The median AUClast was 210.9 day*pg/mL. Among the 5 study patients, the mean breast milk concentration across all study days was 35.95 pg/mL, with an estimated RID of 0.0054% of the maternal dose. CONCLUSION: Minimal concentrations of peginterferon beta-1a were detected in the breast milk samples. These findings may be useful for clinicians considering postpartum MS treatment options.

PURPOSE OF REVIEW: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSDs) are chronic autoimmune demyelinating conditions of the central nervous system often diagnosed in women of childbearing age. Therefore, safe family planning, pregnancy, and postpartum management are important considerations for many patients with MS or NMOSD. RECENT FINDINGS: Many patients with MS can safely become pregnant and remain well throughout pregnancy and the postpartum period with guidance from specialists on treatment planning. During pregnancy, women with NMOSD may face some increased risk of both neurologic and obstetric complications. Recent attention has focused on evaluating the safety of pharmacologic agents during pregnancy and breastfeeding. Unfortunately, care disparities remain common in both MS and NMOSD, and recovery of function is often not optimally managed in the postpartum period. SUMMARY: This article reviews the current state of knowledge on peripartum management in these neurologic conditions and offers practical considerations and case studies. When caring for women with MS and NMOSD of childbearing potential, treatment planning is important to optimize outcomes in both patient and newborn.

BACKGROUND: Peripartum depression (PPD) is underexplored in multiple sclerosis (MS). OBJECTIVE: To evaluate prevalence of and risk factors for PPD in women with MS. METHODS: Retrospective single-center analysis of women with MS with a live birth. Prevalence of PPD was estimated with logistic regression with generalized estimating equations (GEE). GEE evaluated predictors of PPD (e.g. age, marital status, parity, pre-pregnancy depression/anxiety, antidepressant discontinuation, sleep disturbance, breastfeeding, relapses, gadolinium-enhancing lesions, and disability). Factors significant in univariable analyses were included in multivariable analysis. RESULTS: We identified 143 live births in 111 women (mean age 33.1 ± 4.7 years). PPD was found in 18/143 pregnancies (12.6%, 95% CI = 7.3-17.8). Factors associated with PPD included older age (OR 1.16, 95% CI = 1.03-1.32 for 1-year increase), primiparity (OR 4.02, CI = 1.14-14.23), pre-pregnancy depression (OR 3.70, CI = 1.27-10.01), sleep disturbance (OR 3.23, CI = 1.17-8.91), and breastfeeding difficulty (OR 3.58, CI = 1.27-10.08). Maternal age (OR 1.17, CI = 1.02-1.34), primiparity (OR 8.10, CI = 1.38-47.40), and pre-pregnancy depression (OR 3.89, CI = 1.04-14.60) remained significant in multivariable analyses. Relapses, MRI activity, and disability were not associated with PPD. CONCLUSION: The prevalence of PPD in MS appeared similar to the general population, but was likely underestimated due to lack of screening. PPD can affect MS self-management and offspring development, and prospective studies are needed.

BACKGROUND AND OBJECTIVES: Oral delayed-release dimethyl fumarate (DMF) is not recommended during pregnancy and should only be used if the potential benefit justifies the potential fetal risk. Although DMF was well tolerated in clinical trials with consistent safety results in postmarketing surveillance, data are limited in pregnant women. The objective was to provide pregnancy outcomes and DMF exposure information from an interim analysis from a prospective, international registry (TecGistry; NCT01911767). METHODS: Women exposed to DMF from the first day of their last menstrual period before conception or during pregnancy were evaluated. Data were obtained at enrollment; 6-7 months' gestation; 4 weeks after estimated due date; and 4, 12, and 52 weeks after birth. Outcomes included live births, gestational size, pregnancy loss, birth defects, and infant or maternal death after delivery. Outcomes were analyzed cumulatively from October 30, 2013 (the start of TecGistry), to April 8, 2020. RESULTS: Of 345 enrolled patients, median (range) age was 32 (20-43) years. The mean (SD) duration of gestational weeks of DMF exposure was 4.9 (3.8). Most infants were full-term at birth (n = 249/274; 91%) and of average gestational size (n = 190/232; 82%). Of 351 outcomes, 277 were live births; 17 (5%) spontaneous abortions (95% confidence interval [CI] 2.6%-7.1%), including 1 (<1%) molar and 1 (<1%) ectopic pregnancy, were reported. There were 8 (2.9% [95% CI 1.3%-5.6%]) adjudicator-confirmed birth defects among the 277 live births. DISCUSSION: Interim results from this large registry indicate that early DMF exposure was not significantly associated with adverse pregnancy outcomes. Outcomes are consistent with previous smaller reports and with the general population. TRIAL REGISTRATION INFORMATION: TecGistry; clinical trial registration number: NCT01911767.

The availability of vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), provides hope towards mitigation of the coronavirus disease 2019 (COVID-19) pandemic. Vaccine safety and efficacy has not been established in individuals with chronic autoimmune diseases such as multiple sclerosis (MS). Anecdotal reports suggest that the vaccines may be associated with brain, spinal cord, peripheral nervous system, and cardiac inflammation. Based on the high morbidity and unpredictable course of COVID-19, and the need to achieve herd immunity, vaccination has been recommended for patients with MS. We report clinical and MRI features of seven individuals who received the Moderna (n = 3) or Pfizer (n = 4) SARS-CoV-2 mRNA vaccines. Within one to 21 days of either the first (n = 2) or second (n = 5) vaccine dose, these patients developed neurologic symptoms and MRI findings consistent with active CNS demyelination of the optic nerve, brain, and/or spinal cord. Symptoms included visual loss, dysmetria, gait instability, paresthesias, sphincter disturbance, and limb weakness. Age ranged from 24 to 64 (mean 39.1) years; five were woman (71.4%). The final diagnosis was exacerbation of known stable MS (n = 4, two were receiving disease-modifying therapy at the time of vaccination), new onset MS (n = 2), or new onset neuromyelitis optica (n = 1). All responded to corticosteroid (n = 7) or plasma exchange (n = 1) therapy, with five returning to baseline and two approaching baseline. Large prospective studies are required to further investigate any possible relationship between COVID-19 vaccines and acute CNS demyelination.
