Do we use too much PNL in GCA (when not using TCZ)? Could we wean quicker?
Salvarini group n=22
26w PNL weaning protocol from GiACTA, but no TCZ
10/26 in relapse free remission at 1y
Much less PNL, still some steroid AEs
Way of the future for some?

#EULAR2023 #OP0007 What are the recent trends of autoimmune disease (AID)? A database study (22m) in UK showed:
- 1 in 10 people had AID in the last 20yrs
- socioeconomic, seasonal & regional disparities cd influence pathogenesis
- CTD (SLE,pSS,SSc) tended to co-occur @RheumNow https://t.co/3DDPR2K5NC

Autoimmune disease diagnoses slowly on the rise, despite reduced smoking - but that’s now 10% of the population, & many patients have more than one. Most are lifelong.
Surely this needs more investment??

"Ideally, you should get your TA biopsies within 2 weeks, but that's not always possible. Don't delay tx." @anisha_dua reminds us that bx can still be positive up to 8 weeks after steroid initiation. Just be aware of lesional changes with time. #RNL2023 https://t.co/uYBNrGzdQm https://t.co/Rvs0ewHzwb

Dr. Anisha Dua on Imaging in PMR:
- US of shoulders to eval for bursitis can increase specificity
- MRI better for pelvic girdle, but expensive
- Consider PET if lack of response to steroids, r/o malignancy

Avacopan in GPA
- non-inferior to prednisone for induction remission
- received FDA approval for treatment of severe active GPA in combo with standard therapy and steroids
- should be used in newly diagnosed active or relapsing disease

How to long for maintenance of GPA?
Continue for 24 months, then consider:
Relapse history? Organ damage? Toxicity? Patient wishes? Compliance? Family planning?

Rx options for GPA showed by targeted to patient's disease characteristics of severe vs non-severe disease
CYC not for non-severe due to toxicity
MTX, MMF not for severe disease https://t.co/jw3wq2k7gb https://t.co/y3ck6KuCDj

"Highest pre-test probability for GCA is actually:
1) Limb claudication
2) Jaw claudication

Dr. Spiera's approach to PMR treatment
- prefers methylprednisolone
- rapid taper over 16 weeks
- consider GC sparing therapy (MTX, IL-6i)

DMARDs/TNF for PMR:
MTX- initial benefit, but no 5 year steroid sparing effect
Infliximab - no benefit
Lef - some benefit in case series

Is there role for MTX in GCA
Favorable results in a meta-analysis with NNT 11 to prevent 1 cranial relapse
BUT: limitations of meta-analysis, short follow-up, dose response not evaluated
