Recent findings from French registry data have underscored a stark and concerning trend: women with relapsing multiple sclerosis (MS) are significantly less likely to receive treatment compared to their male counterparts. This alarming contrast raises critical issues about gender bias in medical treatment paradigms, particularly in the context of chronic illnesses like MS. The study presented by Dr. Antoine Gavoille at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) annual meeting reveals that this inequity leads to delayed and inadequate care for many affected women, thus jeopardizing their health outcomes and quality of life.
The study in question analyzed data from 22,657 relapsing MS patients, predominantly women (74.2%), with an average onset age of 30. Through a median follow-up of 11.6 years, it was found that women faced a probability of being prescribed any disease-modifying treatment (DMT) significantly lower than men, with odds ratios indicating a troubling trend (OR 0.92). More alarmingly, the likelihood of women receiving high-efficacy DMTs was even less, at an odds ratio of 0.80. These disparities suggest systemic issues within clinical practices and raise questions about “therapeutic inertia,” where delayed treatment can lead to severe long-term implications.
Dr. Sandra Vukusic, co-author of the study, emphasized the repercussions of this “therapeutic inertia” on women’s health. Women not receiving timely or adequate treatment are at a heightened risk of disease progression, which can result in increased lesions and potentially greater long-term disability. The concept of therapeutic inertia here is particularly troubling, as it indicates that opportunities for effective disease control are being squandered. In an era where early intervention with effective DMTs can significantly alter the disease trajectory, the lack of treatment represents a failure not only in practice but also in understanding the unique challenges faced by women.
One of the pivotal factors influencing treatment decisions appears to be concerns about pregnancy and its potential complications. Many neurologists seem to approach the subject with caution, hesitating to prescribe DMTs to women of childbearing age due to apprehensions regarding pregnancy risks. Women, in turn, may exhibit reluctance to pursue available treatments, fearing the unknown effects on their fertility or the health of potential pregnancies. Vukusic points out that this leads to a cycle of under-treatment that persists irrespective of actual pregnancy status, which can further exacerbate health outcomes for women.
The study also shed light on the usage patterns of various DMTs between genders, showing notable differences over time. For instance, medications such as teriflunomide and S1PR-modulators were significantly less utilized by women, while others like glatiramer acetate showed initial equal usage before favoring women in later stages. These discrepancies indicate an evolving landscape in DMT accessibility and acceptance, often overshadowed by the overarching trend of under-treatment in women.
The growing body of evidence demonstrating treatment discrepancies necessitates a reassessment of the clinical decision-making processes specifically tailored for younger women with MS. The data suggest that women are not receiving the most beneficial therapies at optimal times, primarily due to hypothetical risks which may never manifest. A more nuanced understanding of these risks, alongside a willingness to engage women in shared decision-making about their treatment options, could lead to improved care outcomes.
The findings from this significant study highlight a troubling reality in the treatment of relapsing multiple sclerosis, where gender disparities perpetuate a cycle of under-treatment and compromised health outcomes for women. As the understanding of MS evolves, it is imperative that the medical community address these inequities proactively. Developing informed treatment strategies that consider the unique needs and circumstances of women can lead to more equitable healthcare practices and, ultimately, improved health for individuals affected by MS.
