Fatigue as the limiting factor for vaginal birth in patients with multiple sclerosis.
Biringer, Kamil, Sivak, Stefan, Sivakova, Jana et al. · Neuro endocrinology letters · 2021
Quick Summary
This study looked at 15 women with multiple sclerosis (MS) who were pregnant and gave birth between 2015-2020. The researchers found that severe fatigue combined with nerve damage was the main reason why most of these women had caesarean sections instead of vaginal deliveries. The study suggests that better diagnosis and treatment of fatigue during pregnancy might allow more women with MS to have vaginal births safely.
Why It Matters
This study is relevant to ME/CFS research because it identifies fatigue as a major limiting factor in functional capacity during a physiologically demanding event (labour). It highlights how inadequately treated fatigue can drive clinical decision-making and disability escalation, and suggests that improved fatigue characterisation and management may be underutilised in clinical practice. The findings underscore the need for better fatigue assessment tools and treatments applicable across conditions.
Observed Findings
87.5% (14/16 deliveries) resulted in caesarean section; 71.4% were elective procedures
Mean EDSS score at delivery was 2.0±1.5, indicating mild-to-moderate disability
The most common indication for elective CS was combined significant chronic fatigue syndrome and neurological deficit (paresis)
Mean MS disease duration was 9±3.6 years at time of delivery
Patients ranged in age from approximately 27-38 years (mean 32.5±5.3)
Inferred Conclusions
Fatigue in combination with neurological deficit is the primary limiting factor preventing vaginal delivery in pregnant women with MS
Vaginal delivery is not inherently contraindicated in MS patients and should be considered on an individualised basis
More accurate diagnosis and personalised treatment of fatigue could reduce caesarean section rates in this population
Multidisciplinary collaboration between obstetricians, neurologists, and patients is essential for optimal pregnancy management in MS
Remaining Questions
What specific fatigue assessment tools or criteria were used to diagnose 'significant chronic fatigue syndrome' in these patients?
What This Study Does Not Prove
This study does not prove that vaginal delivery is unsafe in MS patients with fatigue, nor does it demonstrate that caesarean section is the optimal choice. It does not establish causation between fatigue severity and delivery outcome—the fatigue may be a marker of overall disability rather than the direct cause of CS indication. The small sample size and lack of control group limits generalisation to the broader MS or ME/CFS populations.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
