🍼 “Stop breastfeeding if on methotrexate” — that’s what we’ve always heard.
But here’s the news 👇
📊 Latest EULAR lactation: Methotrexate = LoE 4 / C
➡️ May be considered in breastfeeding if no safer alternative exists.
💡Not first-line, not forbidden — just evidence-limited. https://t.co/IJEpZYMaFV

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

✳️GDM, antepartum hem, SMM (severe maternal morbidity) -⬆️ in axSpA
✳️Neonat complications-preterm birth
Factors assoc w/SMM- age, comorbidity, gestational age at delivery
Better strategies for maternal care

#ACR25 Abstr#0855 Five extra patients were added to complete IMPACT Open Label Phase 2 trial of add-on Certolizumab in APS women + LAC+ve. Results stood: primary endpoint was met (adverse pregnancy outcome=19.6%; lower than 20% expected). Significant enough to adopt @RheumNow https://t.co/zhFVGYXiaU

A largely understudied area:
Impact of peri-menopause in PsA
Toronto Cohort 473pts, HRT 1.5%
Peri menopause =
increase DAPSA, TJC, SJC, FACIT-fatigue, HAQ
compared to pre- and post-menopause
No association w/ BMI, but with fatigue
Less impact when education level increases https://t.co/bSuGxZCbGn

In the IMPACT trial (Abs 0855), certolizumab met its primary endpoint: <20% had an adverse pregnancy outcome (APO) among females w/ APS & prior APO.
✅ 94% live births, all survived to discharge
📈 Median GA: 37 wks (no APO) vs 31 wks (APO)
