Abstract
BACKGROUND Mothers with multiple sclerosis are at increased risk of preterm birth and small for gestational age infants. Both conditions pose a risk of morbidity, including early-life infections. OBJECTIVE This study aimed to assess the risk of infections in the first 3 years of life among children born preterm or small for gestational age to mothers with multiple sclerosis. METHODS We used Danish national health registers to establish the study cohort of all births by women with MS born from 1995 to 2023. In Cox regression models, we estimated hazard ratios (HRs) of infections in preterm or small for gestational age children. RESULTS Preterm children had an adjusted HR of 1.49 (95% confidence interval (95% CI) 1.15-1.93) for hospital-diagnosed infection and 0.88 (95% CI 0.72-1.06) for antibiotic prescriptions. Small for gestational age children had an adjusted HR of 0.81 (95% CI 0.54-1.22) for hospital-diagnosed infection and 1.07 (95% CI 0.82-1.38) for antibiotic prescriptions. CONCLUSION Children born preterm to mothers with multiple sclerosis had an increased risk of hospital-diagnosed infections in the first 3 years of life, but not of mild-to-moderate infections evaluated on prescriptions. Children born small for gestational age did not have an increased risk of infections.

Abstract
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.

Abstract
BACKGROUND After natalizumab discontinuation severe relapses can occur despite pregnancy, but third trimester exposure is associated with neonatal haematological abnormalities (HA). The best time point for stopping natalizumab during pregnancy is unclear. METHODS Prospective, observational cohort with 350 natalizumab exposed pregnancies from the German Multiple Sclerosis and Pregnancy Registry. Clinical disease activity and neonatal outcomes are compared between women with natalizumab discontinuation during (1st Trim-group) versus after the first trimester (maintaining-group) and for subgroup analysis before (<30-subgroup) or after (≥30-subgroup) the 30th gestational week (gw). RESULTS Baseline characteristics did not significantly differ between the 1st Trim-group (n=179; median exposure duration: 2.60 gw, IQR 1.30-3.60) and the maintaining-group (n=171; median exposure duration: 30.9 gw, IQR 26.9-33.3). Fewer relapses occurred during pregnancy and the postpartum year in the maintaining-group (25.7%) compared with the 1st Trim-group (62.6%; p<0.001). Women in ≥30-subgroup had a significantly lower relapse risk in the first 6 months postpartum (relapse rate ratio: 0.36, 95% CI: 0.15 to 0.84). In total, 7.5% retained meaningful disability 12 months postpartum. No significant effect on neonatal outcomes were observed, but anaemia (OR: 2.62, 95% CI: 1.12 to 6.52) and thrombocytopaenia (OR: 2.64, 95% CI: 1.15 to 6.46) were significantly more common in the ≥30-subgroup. 21.8% of all neonates were born small for gestational age, independent of the timing of natalizumab discontinuation. CONCLUSION Continuing natalizumab during pregnancy after gw 30 decreases the relapse risk postpartum going along with a higher risk for HA in the newborns. These results add relevant knowledge as a basis for informed risk-benefit discussion.

Abstract
BACKGROUND Maternal Multiple Sclerosis (MS) has been associated with an increased risk of adverse birth outcomes. We hypothesized that active disease during conception and pregnancy plays an important role in this context, which this study aims to address. METHODS We used the Danish registers to conduct a nationwide cohort study. Information on maternal disease activity during pregnancy was retrieved using proxies from the linked registers (hospitalization, magnetic resonance imaging of the brain, and use of systemic corticosteroids during pregnancy). Neonates, exposed in utero to maternal disease activity constituted the exposed cohort and the unexposed cohort constituted neonates without in utero exposure to maternal disease activity. The examined outcomes were preterm birth, small for gestational age, low 5-minute Apgar score, and major congenital anomalies. In logistic regression models we estimated the odds ratios (OR) with adjustment for confounders such as maternal age, comorbidities, parity, smoking, calendar year of birth, and disease-modifying treatment. RESULTS Among the study population of 2492 children of mothers with MS we identified 273 (11 %) neonates exposed to maternal disease activity during pregnancy, and 2219 (89 %) neonates without exposure to disease activity. The adjusted odds ratios (aOR) for preterm birth, small for gestational age, low 5-minute Apgar score, and major congenital anomalies among children born to women with disease activity during pregnancy were 0.92 (95 % confidence interval (95 % CI) 0.53-1.60), aOR 1.19 (95 % CI 0.62-2.26), aOR 2.57 (95 % CI 0.93-7.15) and aOR 0.93 (95 % CI 0.48-1.83), respectively. CONCLUSIONS Women with MS having disease activity during pregnancy did not have a statistically significantly increased risk of adverse neonatal outcomes compared to women with MS without disease activity, which is overall reassuring results. We believe, that this will be useful knowledge for patients and clinicians in planning a pregnancy and preparing a birth plan.

Abstract
BACKGROUND We aim to evaluate whether fertility, pregnancy, delivery and breastfeeding have been actually improving in women with multiple sclerosis (MS), compared with general population, and in relation to treatment features. METHODS We included 2018-2020 population-level healthcare data on women with MS living in the Campania region (Italy). Fertility, pregnancy and delivery outcomes were obtained from Certificate of Delivery Assistance; breastfeeding was collected up to 6 months after delivery by trained personnel. RESULTS Out of 2748 women with MS in childbearing age, 151 women delivered 156 babies. Fertility rate was 0.58 live births per woman with MS, compared with 1.29 in Campania region and 1.25 in Italy. Disease-modifying treatment (DMT) continuation during pregnancy was associated with lower birth weight (coeff -107.09; 95% CI -207.91 to -6.26; p=0.03). Exposure to DMTs with unknown/negative effects on pregnancy was associated with birth defects (OR 8.88; 95% CI 1.35 to 58.41; p=0.02). Birth defects occurred in pregnancies exposed to dimethyl fumarate (2/21 exposed pregnancies), fingolimod (1/11 exposed pregnancies) and natalizumab (2/30 exposed pregnancies). After delivery, 18.8% of women with MS were escalated of DMT efficacy, while 50.7% started on same/similar-efficacy DMTs, and 30.5% did not receive DMT. The probability of breastfeeding was higher in women who were treated with breastfeeding-safe DMTs (OR 5.57; 95% CI 1.09 to 28.55; p=0.03). CONCLUSIONS Fertility rate in women with MS remains below the general population. Family planning and subsequent DMT decisions should aim to achieve successful pregnancy, delivery and breastfeeding outcomes, while controlling disease activity.

Abstract
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.

Abstract
Objective To summarize the available literature and provide an overview of in utero exposure to maternal multiple sclerosis (MS) and the influence on offspring health outcomes. Methods We conducted a systematic review by searching Embase, Medline and PubMed.gov databases, and we used covidence.org to conduct a thorough sorting of the articles into three groups; 1) women with MS and the influence on birth outcomes; 2) women with MS treated with disease-modifying therapy (DMT) during pregnancy and the influence on birth outcomes; and 3) women with MS and the influence on long-term health outcomes in the children. Results In total, 22 cohort studies were identified. Ten studies reported on MS without DMT and compared with a control group without MS, and nine studies on women with MS and DMT prior to or during pregnancy met the criteria. We found only four studies reporting on long-term child health outcomes. One study had results belonging to more than one group. Conclusion The studies pointed towards an increased risk of preterm birth and small for gestational age among women with MS. In terms of women with MS treated with DMT prior to or during pregnancy, no clear conclusions could be reached. The few studies on long-term child outcomes all had different outcomes within the areas of neurodevelopment and psychiatric impairment. In this systematic review, we have highlighted the research gaps on the impact of maternal MS on offspring health.

Abstract
BACKGROUND AND PURPOSE Data on pregnancy outcomes following fetal exposure to disease-modifying drugs (DMDs) in women with multiple sclerosis (MS) are sparse although growing. METHODS Data from the Danish Multiple Sclerosis Registry were linked with nationwide registries enabling an investigation of adverse pregnancy outcomes in newborns of women with MS following fetal exposure to injectable first-line treatments, dimethyl fumarate, glatiramer acetate, or natalizumab. Logistic regression models accounting for clustered data were used to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for individual and composite adverse outcomes after adjusting for relevant covariates. RESULTS A total of 1009 DMD-exposed pregnancies were compared with 1073 DMD-unexposed pregnancies as well as 91,112 pregnancies from the general population. No association of an increased risk of any perinatal outcome was found when comparing newborns with fetal exposure with the general population, including preterm birth (OR = 1.19, 95% CI = 0.86-1.64), small for gestational age (OR = 1.38, 95% CI = 0.92-2.07), spontaneous abortion (OR = 1.04, 95% CI = 0.84-1.27), congenital malformation (OR = 0.99, 95% CI = 0.68-1.45), low Apgar score (OR = 0.62, 95% CI = 0.23-1.65), stillbirth (OR = 1.05, 95% CI = 0.33-3.31), placenta complication (OR = 0.53, 95% CI = 0.22-1.27), and any adverse event (OR = 1.10, 95% CI = 0.93-1.30). Similar results were found when comparing DMD-exposed pregnancies with DMD-unexposed pregnancies. CONCLUSIONS We found no increased association of adverse pregnancy outcomes in newborns with fetal exposure to DMDs when compared with either DMD-unexposed pregnancies or the general population.
