The landscape of medical treatment for relapsing multiple sclerosis (MS) has shown remarkable advancements; however, a recent study sheds light on a troubling gender disparity. Research from a French registry points to a consistent pattern where women are less likely than men to receive necessary disease-modifying treatments (DMTs). This analysis looks not only at the implications of this disparity but also challenges the underlying assumptions influencing treatment decisions in the realm of neurology, particularly for women of childbearing age.
The study, conducted by Dr. Antoine Gavoille and his colleagues from Hospices Civils de Lyon, examined a significant cohort of 22,657 patients who were diagnosed with relapsing MS, predominantly women (74.2%). The findings, presented at the ECTRIMS annual meeting in Copenhagen, revealed staggering statistics revealing that women were less likely to receive any form of DMT compared to men. Over the course of a median follow-up of 11.6 years, women were found to have an odds ratio (OR) of 0.92 (95% CI 0.87-0.97) for being treated with any DMT, and an even lower OR of 0.80 (95% CI 0.74-0.86) for high-efficacy DMTs.
Dr. Gavoille’s research emphasizes a phenomenon termed “therapeutic inertia.” This term captures the hesitancy in delivering effective treatments to patients who warrant them—specifically, in this case, women with MS. Dr. Sandra Vukusic, another key figure in the study, articulates the dangers of this inertia: it potentially results in inadequate control of disease activity, which can lead to long-term disability due to accumulated lesions. Therefore, the reluctance to prescribe appropriate therapies may not only diminish the quality of life but also stifle the potential for recovery.
An intriguing aspect of the study delves into the impact of potential pregnancy on the treatment of women with MS. The findings suggest that neurologists may preemptively restrict DMT prescriptions based on concerns regarding pregnancy and its associated risks, even if there’s no immediate intention or possibility of conception. This protective stance, which Dr. Vukusic argues stems from fears of congenital anomalies and adverse pregnancy outcomes, unfortunately perpetuates a cycle of under-treatment.
Moreover, a deeper analysis reveals that treatment disparities did not exclusively stem from pregnancy-related issues. Data analysis shows a notable decline in DMT prescriptions starting approximately nine months before conception, indicating a pattern of undertreatment that transcends pregnancy itself. This leads to an essential question: Are we allowing potential pregnancy concerns to dictate treatment protocols to the detriment of women’s health?
The evaluation of treatment regimens revealed selective underutilization of certain high-efficacy DMTs among women. Drugs such as teriflunomide, S1PR-modulators, and anti-CD20 therapies showed significantly lower usage rates among female patients, with varying patterns of medication adoption over time. Interestingly, drugs like glatiramer acetate and fumarate initially showed equal usage, yet diverged with women ultimately receiving more frequent doses over time.
This gender-based discrepancy underlines the necessity to assess not just the effectiveness of treatments, but also the decision-making frameworks surrounding them. The findings indicate that these treatment disparities often began to manifest five years post-diagnosis for standard DMTs, indicating a proactive approach being stymied by systemic biases.
The revelations presented in this study necessitate a re-evaluation of treatment practices for women diagnosed with relapsing MS. The tendency to limit treatment options based on potential pregnancy-related concerns not only hampers immediate therapeutic intervention but can also result in enduring damage to patients’ health.
Healthcare providers must acknowledge these biases and work toward establishing a treatment protocol that prioritizes effective medical care. Gathering more data on the implications of DMT use concerning pregnancy can empower both neurologists and women with MS to make informed decisions. Ultimately, fostering open communication between healthcare professionals and patients is paramount to ensuring equitable and appropriate treatment paths for all.
