Importance: Understanding the association between pregnancy and clinical outcomes in women with moderate to severe multiple sclerosis (MS) disability is crucial for guiding family planning and management strategies. Objective: To assess peripregnancy relapse activity and disability progression in women with a preconception Expanded Disability Status Scale (EDSS) score of 3 or higher. Design, Setting, and Participants: This multicenter retrospective cohort study used data from the MSBase Registry, with clinical observations spanning 1984 through 2024. Study cohorts included pregnant women with MS with a preconception EDSS score of 3 or higher (range: 3-10, with higher scores indicating more severe MS-related disability) and propensity score-matched nonpregnant women with MS (controls). Main Outcomes and Measures: The main outcomes were peripregnancy annualized relapse rates (ARRs) and time to 6-month confirmed disability worsening (CDW). Results: A total of 1631 women with MS were included, of whom 575 were in the pregnant cohort (median [IQR] age at pregnancy, 32.5 [29.1-36.1] years) and 1056 were in the nonpregnant cohort (median [IQR] age, 32.6 [27.5-37.2] years). The median (range) preconception EDSS score was 3.5 (3.0-7.5). Relapse activity decreased during pregnancy, with a 75% reduction in ARR during the first trimester (rate ratio [RR], 0.25; 95% CI, 0.15-0.43), and increased to 36% above preconception levels in the first 3 months post partum (RR, 1.36; 95% CI, 1.06-1.75). Relapse during pregnancy was associated with a higher preconception ARR (odds ratio [OR], 1.56; 95% CI, 1.10-2.20) and preconception use of natalizumab (OR, 4.42; 95% CI, 1.24-23.57) or fingolimod (OR, 14.07; 95% CI, 2.81-91.30). Older age (OR, 0.92; 95% CI, 0.85-0.99) and continuation of disease-modifying therapy into pregnancy (OR, 0.42; 95% CI, 0.19-1.00) were associated with reduced risk. Disease-modifying therapy reinitiation within 1 month post partum was associated with lower odds of early postpartum relapse (OR, 0.45; 95% CI, 0.23-0.86). There was no significant difference in time to CDW between the pregnant and nonpregnant groups (hazard ratio [HR], 1.15; 95% CI, 0.96-1.38). However, ARR during pregnancy (HR, 1.37; 95% CI, 1.13-1.65) and postpartum EDSS score higher than 4 (HR, 2.69; 95% CI, 1.80-4.03) were associated with shorter time to CDW. Conclusions and Relevance: In this cohort study, women with moderate to severe MS disability exhibited a pattern of peripregnancy relapse activity similar to that reported in women with less disability. Pregnancy was not associated with worse long-term disability outcomes, although optimizing disease control in the peripregnancy period remained critical.

Standardized Definition of Progression Independent of Relapse Activity (Pira) in Relapsing-Remitting Multiple Sclerosis
(Amer Medical Assoc, 2025) Muller, Jannis; Sharmin, Sifat; Lorscheider, Johannes; Ozakbas, Serkan; Karabudak, Rana; Horakova, Dana; Kalincik, Tomas
Importance Progression independent of relapse activity (PIRA) is a significant contributor to long-term disability accumulation in relapsing-remitting multiple sclerosis (MS). Prior studies have used varying PIRA definitions, hampering the comparability of study results. Objective To compare various definitions of PIRA. Design, Setting, and Participants This cohort study involved a retrospective analysis of prospectively collected data from the MSBase registry from July 2004 to July 2023. The participants were patients with MS from 186 centers across 43 countries who had clinically definite relapsing-remitting MS, a complete minimal dataset, and 3 or more documented Expanded Disability Status Scale (EDSS) assessments. Exposure Three-hundred sixty definitions of PIRA as combinations of the following criteria: baseline disability (fixed baseline with re-baselining after PIRA, or plus re-baselining after relapses, or plus re-baselining after improvements), minimum confirmation period (6, 12, or 24 months), confirmation magnitude (EDSS score at/above worsening score or at/above threshold compared with baseline), freedom from relapse at EDSS score worsening (90 days prior, 90 days prior and 30 days after, 180 days prior and after, since previous EDSS assessment, or since baseline), and freedom from relapse at confirmation (30 days prior, 90 days prior, 30 days before and after, or between worsening and confirmation). Main Outcome and Measure For each definition, we quantified PIRA incidence and persistence (ie, absence of a 3-month confirmed EDSS improvement over >= 5 years). Results Among 87 239 patients with MS, 33 303 patients fulfilled the inclusion criteria; 24 152 (72.5%) were female and 9151 (27.5%) were male. At the first visits, the mean (SD) age was 36.4 (10.9) years; 28 052 patients (84.2%) had relapsing-remitting MS, and the median (IQR) EDSS score was 2.0 (1.0-3.0). Participants had a mean (SD) 15.1 (11.9) visits over 8.9 (5.2) years. PIRA incidence ranged from 0.141 to 0.658 events per decade and persistence from 0.753 to 0.919, depending on the definition. In particular, the baseline and confirmation period influenced PIRA detection. The following definition yielded balanced incidence and persistence: a significant disability worsening compared with a baseline (reset after each PIRA event, relapse, and EDSS score improvement), in absence of relapses since the last EDSS assessment, confirmed with EDSS scores (not preceded by relapses within 30 days) that remained above the worsening threshold for at least 12 months. Conclusion and Relevance Incidence and persistence of PIRA are determined by the definition used. The proposed standardized definition aims to enhance comparability among studies.
