@RheumNow #acr20 abs0622 infection induced MPO anca vasc: most common triggers viruses(35.2%), mycobacterial (29.4%)& bacterial inf (29.4%). Onset 3 mo post inf. (70.5%) renal involvement, w/ biopsy-proven GN in 53%. 17.6%died. Rx steroids+abx, CYC in 47%.

Low pre🤰c3/c4 levels assoc'd w/ ⬆ risk of adverse obstetric outcomes in women w/ aPL w/or w/o APS. Pts w/ triple+ aPL and ⬇ c3/c4 predicts a worse prognosis. @RheumNow #ACR20 https://t.co/Cd2TQBfXSe

What happens long-term in Kawasaki disease now? Has IVIG availability fixed this? Pop-based cohort, long follow-up. Turns out cardiac event risk, whilst greatest early, continues >10y after - even in those w/o coronary aneurysms @SickKidsNews @McMasterU #ACR20 ABST0937 @RheumNow https://t.co/1T6JmwhXNb

Ground-breaking news... the end of #glucocorticoid use in #AAV? very exciting to reduce GC toxicity! https://t.co/43eCofpOIX

Use of diagnostic imaging for #GCA is ⬆️ Use of temporal artery biopsy⬇️ data from #MayoClinicRheumatology @garveythomasma1 #acr20 #RheumTwitter https://t.co/kQTg5FTlVq

@drdavidliew @MGHrheumatology @RheumNow That is so interesting. Haptoglobin first described by Paolaggi et al in early 1980s as having potential to monitor PMR/GCA even when ESR normalised. See link here... https://t.co/ERkhUwssox

If TCZ blunts CRP a lot/ESR a fair bit, how can we pick GCA relapses in pts on TCZ? Cool tech (mass spec w tandem mass tag multiplex) on GiACTA samples. Of 344 candidate proteins, guess what ranked highest? Haptoglobin. Let's validate! @MGHrheumatology #ACR20 ABST0513 @RheumNow https://t.co/ErmqZuf2iu

#ACR20 2F053. What is the future for GCA imaging? @RheumNow
