Microbiome may hold key to methotrexate response in RA
Methotrexate (MTX) remains the cornerstone of rheumatoid arthritis (RA) treatment, yet it remains unclear as to how to predict who will respond to it. Two studies presented at ACR (Abstracts 2639 and 2643) suggest the answer may be hiding in the gut.

Accelerated Aging in Rheumatic Disease: From Biology to Lifestyle Intervention
At ACR 2025, the session “27M02: Nutrition for Rheumatic Disease: Where Aging Biology, Sarcopenia, and Diet Intersect” invited the audience to view rheumatic disease through the lens of biological aging and to consider how nutrition and exercise can serve as integrative lifestyle interventions.

Abstract 2360: Single-center lupus pregnancy cohort found that:
🔹 Absence of DORIS remission associated w/ adverse pregnancy outcomes (Pre-term, Pre-eclampsia)
🔹 This is along with known risk factors: antihypertensive use, prior nephritis, active disease

CDAI appropriately guided therapy escalation in RA, but not for everyone. Treatment adjustments were less likely in pts with public or no insurance. Even data-driven care can fall short when access barriers persist.

In healthy women, preeclampsia was more common with:
- increased calprotectin
- decreased anti-CCP (very low levels)
during pregnancy
& this has good predictive capacity for future preeclampsia. Rheum pathophys can give insights into adjacent pathology

DMARD exposure overall during pregnancy is not associated with severe maternal or neonatal morbidity, in this Ontario cohort.
We’re getting better at finding a balance with DMARDs that is safe for both mother and baby. Blanket resistance is harmful
