Priority setting: women's health topics in multiple sclerosis.

Background: A scoping review found that most studies on women's health in multiple sclerosis (MS) focused on pregnancy, fetal/neonatal outcomes and sexual dysfunction. Few studies addressed menopause, contraception, gynecologic cancers/cancer screening. However, the perceived relative importance of these knowledge gaps to people living with MS and other partners is unknown. We engaged a range of partners, including people living with MS, health care providers, researchers, and patient advocacy groups, to set priorities for future research in women's health in MS. Methods: We employed a three-step global engagement process. First, we identified which broad research topics relevant to women's health in MS were of highest priority using two surveys. Second, we developed specific research questions within these topics using focus groups. Finally, we prioritized the research questions with a third survey. Results: Overall, 5,266 individuals responded to the initial surveys [n = 1,430 global survey, mean (SD) age 50.0 (12.6), all continents; n = 3,836 North American Research Committee on Multiple Sclerosis survey, mean (SD) age 64.8 (9.6), United States]. Menopause, sexual dysfunction, pregnancy, gynecologic cancer/cancer screening, hormones and parenthood were identified as the most important topics. Focus groups generated 80 potential research questions related to these topics. In the final survey 712 individuals prioritized these questions. The highest priority questions in each research topic were: (i) How do perimenopause and menopause affect disease activity, course, response to disease-modifying treatment and quality of life in MS; (ii) What are the most effective strategies for managing issues around sexual intimacy, including related to low sexual desire, changes in physical function, and MS symptoms; (iii) Are there long-term effects of disease-modifying therapies on the children of persons with MS; (iv) What are the short and long-term effects of disease-modifying drugs on gynecologic cancer risk, particularly for high efficacy disease-modifying drugs and hematopoietic stem cell transplantation; (v) Are there hormone related treatments that can stabilize fluctuations in MS symptoms; and (vi) How does MS fatigue impact parenting strategies. Conclusion: Priorities for research relating to women's health issues for persons with MS have been delineated using a collaborative process with key partners. Alignment of future research with these priorities should be monitored.

Final analysis of 379 pregnancy outcomes after exposure to dimethyl fumarate in a prospective international registry.

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.

Anti-CD20 monoclonal antibody therapy in postpartum women with neurological conditions.

OBJECTIVE: Postpartum, patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) have increased risk for disease activity. Anti-CD20 IgG1 monoclonal antibodies (mAb) are increasingly used as disease-modifying therapies (DMTs). Patients may wish to both breastfeed and resume DMT postpartum. This study aimed to determine the transfer of anti-CD20 IgG1 mAbs, ocrelizumab, and rituximab (OCR/RTX), into mature breastmilk and describe maternal and infant outcomes. METHODS: Fifty-seven cis-women receiving OCR/RTX after 59 pregnancies and their infants were enrolled and followed up to 12M postpartum or 90 days post-infusion. Breastmilk was collected pre-infusion and serially up to 90 days and assayed for mAb concentration. Medical records and patients' questionnaire responses were obtained to assess neurologic, breastfeeding, and infant development outcomes. RESULTS: The median average concentration of mAb in breastmilk was low (OCR: 0.08 µg/mL, range 0.05-0.4; RTX: 0.03 µg/mL, range 0.005-0.3). Concentration peaked 1-7 days post-infusion in most (77%) and was nearly undetectable after 90 days. Median average relative infant dose was <1% (OCR: 0.1%, range 0.07-0.7; RTX: 0.04%, range 0.005-0.3). Forty-three participants continued to breastfeed post-infusion. At 8-12 months, the proportion of infants' growth between the 3rd and 97th World Health Organization percentiles did not differ for breastfed (36/40) and non-breastfed (14/16, p > 0.05) infants; neither did the proportion with normal development (breastfed: 37/41, non-breastfed: 11/13; p > 0.05). After postpartum infusion, two mothers experienced a clinical relapse. INTERPRETATION: These confirm minimal transfer of mAb into breastmilk. Anti-CD20 mAb therapy stabilizes MS activity before conception to the postpartum period, and postpartum treatments appears to be safe and well-tolerated for both mother and infant.

Specialized palliative care for hospitalized patients with SARS-CoV-2 infection: an analysis of the LEOSS registry.

PURPOSE: Symptom control for patients who were severely ill or dying from COVID-19 was paramount while resources were strained and infection control measures were in place. We aimed to describe the characteristics of SARS-CoV-2 infected patients who received specialized palliative care (SPC) and the type of SPC provided in a larger cohort. METHODS: From the multi-centre cohort study Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS), data of patients hospitalized with SARS-CoV-2 infection documented between July 2020 and October 2021 were analysed. RESULTS: 273/7292 patients (3.7%) received SPC. Those receiving SPC were older and suffered more often from comorbidities, but 59% presented with an estimated life expectancy > 1 year. Main symptoms were dyspnoea, delirium, and excessive tiredness. 224/273 patients (82%) died during the hospital stay compared to 789/7019 (11%) without SPC. Symptom control was provided most common (223/273; 95%), followed by family and psychological support (50% resp. 43%). Personal contact with friends or relatives before or during the dying phase was more often documented in patients receiving SPC compared to patients without SPC (52% vs. 30%). CONCLUSION: In 3.7% of SARS-CoV-2 infected hospitalized patients, the burden of the acute infection triggered palliative care involvement. Besides complex symptom management, SPC professionals also focused on psychosocial and family issues and aimed to enable personal contacts of dying patients with their family. The data underpin the need for further involvement of SPC in SARS-CoV-2 infected patients but also in other severe chronic infectious diseases.

Disease severity in hospitalized COVID-19 patients: comparing routine surveillance with cohort data from the LEOSS study in 2020 in Germany.

INTRODUCTION: Studies investigating risk factors for severe COVID-19 often lack information on the representativeness of the study population. Here, we investigate factors associated with severe COVID-19 and compare the representativeness of the dataset to the general population. METHODS: We used data from the Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS) of hospitalized COVID-19 patients diagnosed in 2020 in Germany to identify associated factors for severe COVID-19, defined as progressing to a critical disease stage or death. To assess the representativeness, we compared the LEOSS cohort to cases of hospitalized patients in the German statutory notification data of the same time period. Descriptive methods and Poisson regression models were used. RESULTS: Overall, 6672 hospitalized patients from LEOSS and 132,943 hospitalized cases from the German statutory notification data were included. In LEOSS, patients above 76 years were less likely represented (34.3% vs. 44.1%). Moreover, mortality was lower (14.3% vs. 21.5%) especially among age groups above 66 years. Factors associated with a severe COVID-19 disease course in LEOSS included increasing age, male sex (adjusted risk ratio (aRR) 1.69, 95% confidence interval (CI) 1.53-1.86), prior stem cell transplantation (aRR 2.27, 95% CI 1.53-3.38), and an elevated C-reactive protein at day of diagnosis (aRR 2.30, 95% CI 2.03-2.62). CONCLUSION: We identified a broad range of factors associated with severe COVID-19 progression. However, the results may be less applicable for persons above 66 years since they experienced lower mortality in the LEOSS dataset compared to the statutory notification data.

Seizure Semiology in Antibody-Associated Autoimmune Encephalitis.

BACKGROUND AND OBJECTIVES: To assess seizure characteristics in antibody (ab)-associated autoimmune encephalitis (ab + AE) with the 3 most prevalent abs against N-methyl-d-aspartate receptor (NMDAR), leucine-rich glioma-inactivated protein 1 (LGI1), and glutamic acid decarboxylase (GAD). METHODS: Multicenter nationwide prospective cohort study of the German Network for Research in Autoimmune Encephalitis. RESULTS: Three hundred twenty patients with ab + AE were eligible for analysis: 190 NMDAR+, 89 LGI1+, and 41 GAD+. Seizures were present in 113 (60%) NMDAR+, 69 (78%) LGI1+, and 26 (65%) GAD+ patients and as leading symptoms for diagnosis in 53 (28%) NMDAR+, 47 (53%) LGI+, and 20 (49%) GAD+ patients. Bilateral tonic-clonic seizures occurred with almost equal frequency in NMDAR+ (38/51, 75%) and GAD+ (14/20, 70%) patients, while being less common in LGI1+ patients (27/59, 46%). Focal seizures occurred less frequently in NMDAR+ (67/113; 59%) than in LGI1+ (54/69, 78%) or in GAD+ patients (23/26; 88%). An aura with déjà-vu phenomenon was nearly specific in GAD+ patients (16/20, 80%). Faciobrachial dystonic seizures (FBDS) were uniquely observed in LGI1+ patients (17/59, 29%). Status epilepticus was reported in one-third of NMDAR+ patients, but only rarely in the 2 other groups. The occurrence of seizures was associated with higher disease severity only in NMDAR+ patients. DISCUSSION: Seizures are a frequent and diagnostically relevant symptom of ab + AE. Whereas NMDAR+ patients had few localizing semiological features, semiology in LGI1+ and GAD+ patients pointed toward a predominant temporal seizure onset. FBDS are pathognomonic for LGI1 + AE. Status epilepticus seems to be more frequent in NMDAR + AE.

COVID-19 mortality in cirrhosis is determined by cirrhosis-associated comorbidities and extrahepatic organ failure: Results from the multinational LEOSS registry.

BACKGROUND AND OBJECTIVE: International registries have reported high mortality rates in patients with liver disease and COVID-19. However, the extent to which comorbidities contribute to excess COVID-19 mortality in cirrhosis is controversial. METHODS: We used the multinational Lean European Open Survey on SARS-CoV-2-infected patients (LEOSS) to identify patients with cirrhosis documented between March 2020 and March 2021, when the wild-type and alpha variant were predominant. We compared symptoms, disease progression and mortality after propensity score matching (PSM) for age, sex, obesity, smoking status, and concomitant diseases. Mortality was also compared with that of patients with spontaneous bacterial peritonitis (SBP) without SARS-CoV-2 infection, a common bacterial infection and well-described precipitator of acute-on-chronic liver failure. RESULTS: Among 7096 patients with SARS-CoV-2 infection eligible for analysis, 70 (0.99%) had cirrhosis, and all were hospitalized. Risk factors for severe COVID-19, such as diabetes, renal disease, and cardiovascular disease were more frequent in patients with cirrhosis. Case fatality rate in patients with cirrhosis was 31.4% with the highest odds of death in patients older than 65 years (43.6% mortality; odds ratio [OR] 4.02; p = 0.018), Child-Pugh class C (57.1%; OR 4.00; p = 0.026), and failure of two or more organs (81.8%; OR 19.93; p = 0.001). After PSM for demographics and comorbidity, the COVID-19 case fatality of patients with cirrhosis did not significantly differ from that of matched patients without cirrhosis (28.8% vs. 26.1%; p = 0.644) and was similar to the 28-day mortality in a comparison group of patients with cirrhosis and SBP (33.3% vs. 31.5%; p = 1.000). CONCLUSIONS: In immunologically naïve patients with cirrhosis, mortality from wild-type SARS-CoV-2 and the alpha variant is high and is largely determined by cirrhosis-associated comorbidities and extrahepatic organ failure.

Peginterferon beta-1a concentrations in breast milk of lactating multiple sclerosis patients.

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.

Interim Analysis of Pregnancy Outcomes After Exposure to Dimethyl Fumarate in a Prospective International Registry.

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.

Effect of ofatumumab on pregnancy, parturition, and lactation in cynomolgus monkeys.

Knowledge of the impacts of the anti-CD20 monoclonal antibody ofatumumab on the developing immune system is limited. This study examined the effects of intravenous ofatumumab on pregnancy, parturition, and lactation, and on pre- and postnatal survival and development in cynomolgus monkeys, an established model for developmental toxicity assessment. Pregnant cynomolgus monkeys (n = 42) were randomized to receive vehicle only (control group; n = 14), low-dose ofatumumab (n = 14), or high-dose ofatumumab (n = 14). Survival, clinical outcomes, and clinical pathology investigations were evaluated regularly until lactation day (maternal animals) and postnatal day 180±1 (infants). Anatomic pathology was investigated in euthanized infants and unscheduled terminations of maternal animals and infants. Ofatumumab treatment was not associated with maternal toxicity or embryotoxicity and had no effect on the growth and development of offspring. As expected, B-cell depletion occurred in maternal animals and their offspring, with a reduced humoral immune response in infants of mothers on high-dose ofatumumab. Both effects were reversible. In the high-dose group, perinatal deaths of 3 infants were attributed to infections, potentially secondary to pharmacologically induced immunosuppression. The no-observed adverse-effect level for initial/maintenance ofatumumab doses was 100/20 mg, and 10/3 mg/kg for pharmacological effects in infant animals, which are associated with exposures significantly higher than those following therapeutic doses in humans. In this study with cynomolgus monkeys, ofatumumab treatment was not associated with maternal toxicity or embryotoxicity and had no effect on the growth and development of offspring.

Averting multiple sclerosis long-term societal and healthcare costs: The Value of Treatment (VoT) project.

BACKGROUND AND PURPOSE: The recent report on Value-of-Treatment (VoT) project highlights the need for early diagnosis-intervention, integrated, seamless care underpinning timely care pathways and access to best treatments. The VoT-multiple-sclerosis (MS) economic case study analysis aimed to estimate the effectiveness/cost-effectiveness of both early treatment and reducing MS risk factors (e.g. smoking and vitamin D insufficiency). METHODS: A series of decision analytical modellings were developed and applied to estimate the cost-effectiveness of: (1) reducing the conversion from clinically-isolated-syndrome (CIS) to clinically-definite-MS (CDMS); (2) smoking cessation and increase of 25 hydroxyvitamin D (25(OH)D) serum level. Both (1) and (2) considered socioeconomic impact on averted MS disability progression. Costs were reported for societal and healthcare provider perspectives (pending on data across nations; Euros). Effectiveness was expressed as Quality-Adjusted-Life-Years (QALYs) gains. Long term (25, 30, 40,50-years) and short (one-year) timelines were considered for (1) and (2), respectively. RESULTS: Early treatment was cost-effective for the health care provider and both cost-effective/cost-saving for the society across time-horizons and nations. Smoking cessation and an increase of 25(OH)D in MS patients were both cost-effective/cost-saving across nations. CONCLUSIONS: To the best of our knowledge, our work provides the first economic evidence to base appropriate public health interventions to reduce the MS burden in Europe.

The MSBase pregnancy, neonatal outcomes, and women's health registry.

BACKGROUND: Family planning and pregnancy decisions are key considerations in the management of women with multiple sclerosis (MS), who are typically diagnosed between the ages of 20-40 years. Despite a strong evidence base that pregnancy is not harmful for women with MS, many knowledge gaps remain. These include: best management strategies through pregnancy in the era of highly effective disease-modifying therapies (DMT); foetal risks associated with DMT exposure in utero or in relation to breastfeeding; knowledge base around the use of assisted reproductive technologies; the long-term impact of pregnancy on disease outcomes, as well as the impact of long-term DMT use on women's health and cancer risk. METHODS: Here, we describe the new MSBase pregnancy, neonatal outcomes and women's health registry. We provide the rationale for, and detailed description of, the variables collected within the registry, together with data acquisition details. CONCLUSION: The present paper will act as a reference document for future studies.

Treatment response to cyclophosphamide, rituximab, and bortezomib in chronic immune-mediated sensorimotor neuropathies: a retrospective cohort study.

BACKGROUND: Up to 20% of patients with chronic immune-mediated sensorimotor neuropathies (CIN) do not respond adequately to first-line therapies. However, studies on further treatment are scarce. METHODS: We analyzed retrospectively 200 CIN patients regarding disease characteristics and response to therapy with cyclophosphamide (CYP), rituximab (RTX), and bortezomib (BTZ). Treatment response was defined as improvement or stabilization of inflammatory neuropathy cause and treatment overall disability score (INCAT-ODSS). RESULTS: A total of 48 of 181 patients (26.5%) received therapy with CYP, RTX, or BTZ. The most frequently and first used therapy was CYP (69%). More than 40% of patients needed a second or third treatment. Overall, 71 treatments were applied in 48 patients. The combination of up to all three treatments enhanced the response-rate to 90%. Treatment within 24 months after initial diagnosis resulted in significantly higher response rate than late treatment (79% versus 50 %, p = 0.04, χ 2-test, n = 46) and in lower disability in long-term follow up (INCAT-ODSS 3.8 versus 5.8, p = 0.02, t-test, n = 48). Patients with Lewis-Sumner syndrome (n = 9) and autoantibody mediated neuropathies (n = 13) had excellent response rates after treatment with RTX (90-100%). In contrast, typical chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) showed a response rate of 64% in CYP, 64% in RTX, and 75% in BTZ. CONCLUSION: Treatment with CYP, RTX, or BTZ was effective in this cohort of CIN refractory to first-line treatment. Our data increase evidence for an early use of these therapies. High efficacy of RTX in Lewis-Sumner syndrome in contrast to typical CIDP suggests a distinct pathophysiology.

First results of the "Lean European Open Survey on SARS-CoV-2-Infected Patients (LEOSS)".

PURPOSE: Knowledge regarding patients' clinical condition at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection is sparse. Data in the international, multicenter Lean European Open Survey on SARS-CoV-2-Infected Patients (LEOSS) cohort study may enhance the understanding of COVID-19. METHODS: Sociodemographic and clinical characteristics of SARS-CoV-2-infected patients, enrolled in the LEOSS cohort study between March 16, 2020, and May 14, 2020, were analyzed. Associations between baseline characteristics and clinical stages at diagnosis (uncomplicated vs. complicated) were assessed using logistic regression models. RESULTS: We included 2155 patients, 59.7% (1,287/2,155) were male; the most common age category was 66-85 years (39.6%; 500/2,155). The primary COVID-19 diagnosis was made in 35.0% (755/2,155) during complicated clinical stages. A significant univariate association between age; sex; body mass index; smoking; diabetes; cardiovascular, pulmonary, neurological, and kidney diseases; ACE inhibitor therapy; statin intake and an increased risk for complicated clinical stages of COVID-19 at diagnosis was found. Multivariable analysis revealed that advanced age [46-65 years: adjusted odds ratio (aOR): 1.73, 95% CI 1.25-2.42, p = 0.001; 66-85 years: aOR 1.93, 95% CI 1.36-2.74, p < 0.001; > 85 years: aOR 2.38, 95% CI 1.49-3.81, p < 0.001 vs. individuals aged 26-45 years], male sex (aOR 1.23, 95% CI 1.01-1.50, p = 0.040), cardiovascular disease (aOR 1.37, 95% CI 1.09-1.72, p = 0.007), and diabetes (aOR 1.33, 95% CI 1.04-1.69, p = 0.023) were associated with complicated stages of COVID-19 at diagnosis. CONCLUSION: The LEOSS cohort identified age, cardiovascular disease, diabetes and male sex as risk factors for complicated disease stages at SARS-CoV-2 diagnosis, thus confirming previous data. Further data regarding outcomes of the natural course of COVID-19 and the influence of treatment are required.

Pregnancy outcomes and postpartum relapse rates in women with RRMS treated with alemtuzumab in the phase 2 and 3 clinical development program over 16 years.

BACKGROUND: Relapsing-remitting multiple sclerosis (RRMS) is frequently diagnosed in women of reproductive age. Because the use of disease-modifying therapies (DMTs) early in the disease course is increasing, it is important to evaluate the safety of DMTs in pregnant women and their developing fetuses. Alemtuzumab, approved for the treatment of relapsing forms of MS, is administered as 2 courses of 12 mg/day on 5 consecutive days at baseline and on 3 consecutive days 12 months later. Alemtuzumab is eliminated from the body within approximately 30 days after administration; it is recommended that women of childbearing potential use effective contraception during and for 4 months after treatment. Here, we report pregnancy outcomes in alemtuzumab-treated women from the phase 2 and 3 clinical development program over 16 years. METHODS: We followed 972 women who had alemtuzumab in phase 2 (CAMMS223 [NCT00050778]) and phase 3 (CARE-MS I [NCT00530348], CARE-MS II [NCT00548405]) studies, and/or in 2 consecutive extension studies (NCT00930553; NCT02255656 [TOPAZ]). In the extension studies, patients could receive additional alemtuzumab (12 mg/day on 3 days; ≥12 months apart) as needed for disease activity. All women who received alemtuzumab in the clinical development program were included. Pregnant or lactating patients were followed up for safety. RESULTS: As of November 26, 2018, 264 pregnancies occurred in 160 alemtuzumab-treated women, with a mean age at conception of 32.6 years, and mean time from last alemtuzumab dose to conception of 35.9 months. Of the 264 pregnancies, 233 (88%) were completed, 11 (4%) were ongoing, and 20 (8%) had unknown outcomes; 16 (6%) conceptions occurred within 4 months, and 5 conceptions within 1 month of the last alemtuzumab dose. Of the 233 completed pregnancies with known outcomes, there were 155 (67%) live births with no congenital abnormalities or birth defects, 52 (22%) spontaneous abortions, 25 (11%) elective abortions, and 1 (0.4%) stillbirth. Maternal age was associated with an increased risk of spontaneous abortion in alemtuzumab-treated patients (<35 years: 15%; ≥35 years: 37%; relative risk [RR], 2.46 [95% CI: 1.53-3.95], p=0.0002). Risk of spontaneous abortion was not increased in patients becoming pregnant ≤4 months versus >4 months since alemtuzumab exposure (19% vs 23%; RR, 1.08 [95% CI: 0.41-2.85], p=0.88). Autoimmune thyroid adverse events did not increase risk for spontaneous abortion (patients with vs without thyroid adverse events, 23.7% vs 21.3%; RR, 1.11 [95% CI: 0.69-1.80], p=0.75). Annualized relapse rate was 0.10 and 0.12 in the 2 years prior to pregnancy (post alemtuzumab), and was 0.22, 0.12, and 0.12 in each of the first 3 years postpartum, respectively. CONCLUSION: Normal live births were the most common outcome in women exposed to alemtuzumab 12 mg or 24 mg in clinical studies. Spontaneous abortion rate in alemtuzumab-treated patients was comparable with rates in the general population and treatment-naive MS patients, and was not increased in women with pregnancy onset within 4 months of alemtuzumab exposure. There was a minimal increase in postpartum relapses.

Extensive immune reconstitution inflammatory syndrome in Fingolimod-associated PML: a case report with 7 Tesla MRI data.

BACKGROUND: Progressive multifocal leukoencephalopathy (PML) is a rare complication of patients treated with fingolimod. CASE PRESENTATION: Routine MRI eventually led to diagnosis of asymptomatic early PML that remained stable after discontinuation of fingolimod. As blood lymphocyte counts normalized, signs of immune reconstitution inflammatory syndrome (IRIS) and renewed MS activity developed. Both, advanced laboratory and ultrahigh field MRI findings elucidated differences between PML and MS. CONCLUSIONS: In our case, early discontinuation of fingolimod yielded a good outcome, lymphocyte counts reflected immune system activity, and paraclinical findings helped to differentiate between PML-IRIS and MS.

Alemtuzumab as rescue therapy in a cohort of 50 relapsing-remitting MS patients with breakthrough disease on fingolimod: a multi-center observational study.

BACKGROUND: Relapsing-remitting multiple sclerosis (RRMS) requires efficient immunomodulatory treatment to reach "no evidence of disease activity" status at best. Alemtuzumab and fingolimod have proved to be efficient options in RRMS with active disease course. Yet, side effects and break-through disease may limit long-time treatment and necessitate switch of medication. Data on efficacy and safety of alemtuzumab following fingolimod treatment are limited, but useful for clinical practice. METHODS: Clinical and MRI data of 50 RRMS patients with a history of therapy switch from fingolimod to alemtuzumab were retrospectively analyzed. Data were acquired from nine large German MS Centers from 2013 to 2016 and analyzed using descriptive statistics. RESULTS: On average, patients with disease duration of 12.9 years and median EDSS of 3.0 at baseline switched to alemtuzumab after 68 weeks of fingolimod treatment. Thereafter, patients on alemtuzumab were followed for a mean of 64 weeks. The annualized relapse rate decreased from 2.2 in the year prior to 0.34 in the following year after switching to alemtuzumab and EDSS stabilized. In a subgroup of patients (n = 23), MRI data point to a reduction in enhancing (4.47 vs. 0.26) and new/enlarging T2 lesions (5.8 vs. 0.27) after treatment adjustment. Side effects were generally as expected from published data for alemtuzumab (autoimmunity 2/50, severe infections 1/50). One patient suffered combined lethal necrotizing leukoencephalopathy and hemolytic anemia. DISCUSSION: Therapy switch was highly effective in reducing clinical and MRI surrogates of disease activity and was mainly well tolerated within one year of follow-up. Hence, alemtuzumab constitutes a promising therapy in RRMS with refractory disease activity despite fingolimod treatment. Further studies are warranted to confirm these beneficial findings and to reveal safety concerns in the longer-term follow-up.

Successful pregnancy after natalizumab-associated progressive multifocal leukoencephalopathy in a patient with multiple sclerosis.

We report the case of a post-progressive multifocal leukoencephalopathy (PML), multiple sclerosis (MS) patient with an uncomplicated pregnancy and delivery. A 28-year-old woman on natalizumab (total of 49 infusions) was diagnosed with PML due to typical magnetic resonance imaging (MRI) and clinical presentation. John Cunningham virus (JCV) was detected in the cerebrospinal fluid (CSF) during the immune reconstitution inflammatory syndrome (IRIS). Nine months after PML onset, JCV negativity in the CSF was observed. MS was stabilised with dimethyl fumarate (DMF), and 18 months later, a desired pregnancy was reported, resulting in the birth of a healthy boy. Our report gives new hope regarding family planning for post-PML patients.

Predictors of severity and functional outcome in natalizumab-associated progressive multifocal leukoencephalopathy.

OBJECTIVE: Progressive multifocal leukoencephalopathy (PML) is an emerging complication of immunosuppressive therapies, especially natalizumab in multiple sclerosis (MS). Factors associated with functional outcome of natalizumab-associated PML (natalizumab-PML) have not been sufficiently described. METHODS: We retrospectively analyzed medical records of all patients with natalizumab-PML ( n = 32) treated in our hospital since 2009. Disability measured by Expanded Disability Status Scale (EDSS) at two different time points (highest available EDSS during PML and last available EDSS after PML diagnosis) served as functional outcome parameters. Clinical, laboratory, and imaging data were analyzed for association with functional outcome by applying Spearman's rho and multivariate regression analysis. RESULTS: In all, 31/32 patients survived PML. A poor functional outcome was associated with higher age, higher initial John Cunningham virus (JCV) copy number in cerebrospinal fluid (CSF), and more extensive PML lesions on initial magnetic resonance imaging (MRI). No association between functional outcome and the duration of natalizumab therapy or a delayed PML diagnosis was observed. CONCLUSION: This study will be useful for neurological practice to estimate functional outcome or disease severity of natalizumab-PML in primary care settings.

Relevance of endoglin, IL-1α, IL-1ß and anti-ovarian antibodies in females with multiple sclerosis.

Few studies support the concept of reduced fertility in females with multiple sclerosis (MS). Recently we reported on reduced serum levels of Anti-Müllerian Hormone (AMH) in reproductive-age females with MS, suggestive of reduced ovarian reserve. The cause for this observation is not evident and remains speculative. The aim of the study is to examine possible immunological mechanisms interfering with fertility, as well as ovarian reserve that might affect the reproductive potential in women with MS. ELISA experiments were done to detect anti-ovarian antibodies (AOA), endoglin and interleukin (IL)-1α/-1ß in sera of 85 MS females, including 15 women with known low AMH level as a marker of ovarian reserve, compared to 63 healthy controls. Groups did not differ with respect to age, smoking habits, BMI, and use of oral contraceptives. MS females showed significantly increased endoglin values compared to healthy controls. Remarkable, the highest endoglin values were found in subjects with low AMH. AOA were neither detectable in MS patients nor control subjects. IL-1α and IL-1ß levels did not differ between groups. Our data established no relevance of IL-1α/-1ß or AOA in ovarian insufficiency/dysfunction but suggests the involvement of endoglin in RRMS.
