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

Optimizing the "Time to pregnancy" in women with multiple sclerosis: the OPTIMUS Delphi survey

Background

The debate on how to manage women affected by multiple sclerosis (MS) during reproductive age is still open, as is the issue of fertility in such patients. Main issue regard the identification of the optimal window for pregnancy and how to deal with medical therapy before and during conception. The aim of this Delphi consensus was to collect the opinions of a multidisciplinary group, involving reproductive medicine specialists and neurologists with experience in the management of multiple sclerosis women with reproductive desire.

Methods

Four experts plus scientific coordinators developed a questionnaire distributed online to 10 neurologists and later discussed the responses and amended a list of statements. The statements were then distributed via an online survey to 23 neurologists (comprising the first 10), who voted on their level of agreement/disagreement with each statement. Consensus was achieved if agreement or disagreement with a statement exceeded 66%.

Results

Twenty-one statements reached consensus after two rounds of voting, leading to the following main recommendations: (1) Fertility evaluation should be suggested to wMS, in case of the need to shorten time to pregnancy and before treatment switch in women on DMTs contraindicated in pregnancy, particularly in case of highly active disease and age > 35 years. (2) ART should not be discouraged in wMS, but the use of DMTs until pregnancy confirmation should be suggested; ART may be considered in order to reduce time to pregnancy in MS women with a reduced ovarian reserve and/or age > 35 years, but in case of an expected poor ART prognosis and the need for more than one ART cycle, a switch to a high-efficacy DMD before ART should be offered. (3) Oocyte cryopreservation may be considered in women with reduced ovarian reserve, with unpredictable time to complete diagnostic workup and achieve disease control; a risk/cost-benefit analysis must be performed in women >35 years, considering the diminished ovarian reserve.

Conclusion

This consensus will help MS neurologists to support family planning in wMS, respecting MS therapeutic needs while also taking into account the safety and impact of advancing age on fertility.

Ovarian reserve in patients with multiple sclerosis: A systematic review and meta-analysis

OBJECTIVE

To summarize recent evidence about ovarian reserve markers in women affected by multiple sclerosis (MS) compared with healthy controls, as women with MS seem to be characterized by lower anti-Müllerian hormone (AMH) levels.

METHODS

The research was conducted using PubMed (MEDLINE), Scopus, ClinicalTrial.gov, OVID and Cochrane Library from inception of each database to June 30, 2022. Studies comparing ovarian reserve markers between women with MS and healthy controls were considered eligible for inclusion. The primary outcome was serum AMH (ng/mL) levels. Results were reported as pooled odds ratio (OR) for categorical outcomes and as mean difference (MD) for continuous variables, with their 95% confidence intervals (CIs). The random effect model of DerSimonian and Laird was adopted for all analyses. A P-value less than 0.05 was considered significant.

RESULTS

Serum AMH circulating levels were not significantly different (MD -0.25, 95% CI -0.83 to 0.32; P = 0.390), as well as blood levels of follicle-stimulating hormone or ovarian volume. However, antral follicle count (AFC) and estradiol blood levels were significantly lower, and luteinizing hormone (LH) levels were significantly higher in women with MS than in controls.

CONCLUSION

A significant difference in AFC, estradiol and LH levels was observed, but not for AMH levels.

Cause or consequence? The role of IL-1 family cytokines and receptors in neuroinflammatory and neurodegenerative diseases

Cytokines and receptors of the IL-1 family are key mediators in innate immune and inflammatory reactions in physiological defensive conditions, but are also significantly involved in immune-mediated inflammatory diseases. Here, we will address the role of cytokines of the IL-1 superfamily and their receptors in neuroinflammatory and neurodegenerative diseases, in particular Multiple Sclerosis and Alzheimer's disease. Notably, several members of the IL-1 family are present in the brain as tissue-specific splice variants. Attention will be devoted to understanding whether these molecules are involved in the disease onset or are effectors of the downstream degenerative events. We will focus on the balance between the inflammatory cytokines IL-1β and IL-18 and inhibitory cytokines and receptors, in view of future therapeutic approaches.

What Can We Learn from Sex Differences in MS?

Multiple sclerosis (MS) is the major acquired central nervous system disease of young adults. It is a female predominant disease. Multiple aspects of MS are influenced by sex-based differences. This has become an important area of research and study. It teaches us how the impact of sex on a disease can lead to new insights, guidelines, management, and treatments.

Baseline and overtime variations of soluble adhesion molecule plasma concentrations are associated with mobility recovery after rehabilitation in multiple sclerosis patients

Rehabilitative exercise outcomes and plasma concentrations of soluble adhesion molecules (sEndoglin, sE-Selectin, sL-Selectin, sICAM-1, sNCAM, sNCAM-1, sVCAM-1, sPECAM-1, sVAP-1) were evaluated in 60 severely disabled progressive multiple sclerosis (MS) patients at 4-time points. Changes of sE-Selectin, sL-Selectin, and sPECAM-1 concentrations were observed over time, and their variations were significantly correlated with rehabilitative outcome variations. Baseline sVAP-1 concentrations were able to predict functional mobility recovery. Our data suggest that the evaluation of adhesion molecules in plasma provides useful information to interpret rehabilitative exercise processes and to identify potential predictors of the rehabilitation-induced changes in mobility outcomes in MS patients.

Treatment of multiple sclerosis during pregnancy - safety considerations

INTRODUCTION

Women with multiple sclerosis (MS) are treated early in the disease course with disease modifying therapies (DMT). Updated information is needed on pregnancy outcomes of DMT-exposed pregnancies and the effect of the drug withdrawal on MS disease activity. Areas covered: In this review, we will cover the most important updated management strategies in planning a pregnancy when having MS. Expert opinion: MS itself does not increase the risk of adverse pregnancy outcomes and does not negatively influence the long-term course of the disease. As MS became a treatable disease, management of DMTs before, during and after pregnancy is important. This requires updated knowledge on safety of DMTs as well as data of the effect on disease activity after drug withdrawal. A special challenge is the handling of women with highly active MS, as pregnancy might not be powerful enough to suppress the risk of rebound relapses. Exclusive breastfeeding is an option for many women who want to do so, but in cases of high disease activity and those women who do not want to breastfeed, early reintroduction of MS therapies should be considered.
