Recent research presented at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) has unearthed concerning data regarding the treatment of relapsing multiple sclerosis (MS) patients. The study, led by Dr. Antoine Gavoille of Hospices Civils de Lyon in France, highlights a significant gender gap, revealing that women are less likely than men to receive disease-modifying treatments (DMTs) for MS. This situation raises alarms about the fairness and efficacy of treatment protocols in managing an already complex and debilitating disease.
The dataset analyzed encompassed 22,657 patients diagnosed with relapsing MS, predominantly consisting of women (74.2%) with an average onset age of 30 years. Over an extensive follow-up period averaging 11.6 years, notable disparities emerged. Women exhibited a markedly lower probability of being treated with any DMT (odds ratio 0.92) and particularly high-efficacy DMTs (odds ratio 0.80). These statistics foreground the phenomenon often referred to as “therapeutic inertia,” where treatment decisions are suboptimal, ultimately resulting in adverse disease trajectories for women.
Co-author Dr. Sandra Vukusic identified this gap as a lost opportunity in patient care, indicating that the delay in treatment during DMT-free periods leads to an accumulation of lesions. Such progression exacerbates the risk for long-term disability, intensifying the need for immediate and effective therapeutic intervention.
The decision-making process surrounding MS treatments is intricate and fraught with nuances, especially for women in their childbearing years. Dr. Gavoille posits that preconceived plans for pregnancy influence neurologists’ decisions when it comes to prescribing DMTs. This hesitancy can lead to a systematic under-treatment of women, who may not even be pregnant but are still affected by these considerations.
Moreover, Dr. Vukusic articulates the psychological burden on female patients, who may experience discomfort when their healthcare providers exhibit uncertainty regarding pregnancy-related issues. Women naturally prioritize the health of potential pregnancies, often foregoing effective treatment due to fear of potential risks to their fetus. Therefore, the treatment abyss widens, not solely due to clinical factors but also because of societal and psychological challenges.
The study further indicates variability in the prescription of specific DMTs among genders over time. For instance, DMTs like teriflunomide and S1PR-modulators were disproportionately less used by women throughout their availability. In contrast, medications such as glatiramer acetate began with equal utilization rates but showed a subsequent increase in prescribing for women. This variability emphasizes the need to understand the underlying causes of treatment disparities, which may relate to both routine clinical biases and the evolving nature of treatment guidelines.
A subanalysis revealed that treatment inadequacies were pronounced outside the pregnancy and postpartum periods, indicating a pattern of withdrawal from effective medications well in advance of conception. This suggests that while pregnancy plays a role in the treatment gap, it does not provide a complete explanation.
The findings encourage a critical reassessment of how treatment decisions are formulated for young women diagnosed with MS. Dr. Vukusic stresses the necessity of empowering women by providing them with the best therapies at the appropriate times, irrespective of potential pregnancy concerns that may never materialize.
There exists a compelling need for clinicians to engage in informed conversations with female patients about treatment options, alleviating fears regarding the impacts of DMTs on future pregnancies. Furthermore, research striving to establish clearer guidelines concerning the safety of DMTs during pregnancy could significantly influence treatment practices and empower women in their MS management.
The stark disparity in MS treatment between genders emphasizes the pressing need for change within the healthcare system. All stakeholders, from physicians to data analysts, should be cognizant of these disparities to foster equitable care for all MS patients. Addressing the roots of therapeutic inertia and revisiting treatment protocols could yield better clinical outcomes for women with relapsing MS, ultimately paving the way for a more inclusive and effective approach to managing this challenging disease.
