The treatment paradigm for Giant Cell Arteritis (GCA) has been a binary approach to the presence or absence of vasculitis. When GCA is present, we institute high doses of glucocorticoids for treatment of the inflammatory process. This approach is not well individualized to the patient as we do not account for the degree of inflammation that may or may not be present in the disease. Improved markers to stratify the extent of inflammation can help to tailor a more personalized approach to treatment.

This has been an interesting ACR meeting in terms of PMR updates. I would argue that we are still far too wedded to glucocorticoids only in the management of PMR. Yes, some patients will do fine with just glucocorticoids but we persist far too long with a glucocorticoid only strategy in others who clearly need an alternative as glucocorticoid adverse events multiply.

JAK inhibitors in GCA?
We have a phase 3 trial in giant cell arteritis back on the opening day plenary stage. The SELECT-GCA study, looking at upadacitinib in GCA, was scheduled to anchor the #ACR24 opening plenary for a reason - it is highly notable and badly needed.… https://t.co/aJ3uao1wD7 https://t.co/6ao2OoODHg

Hypoxia seems to exacerbate neutrophil activation by ANCA
- enhanced F-Actin polymerization
- enhanced NET formation
Could hypoxia predilection in certain tissues (kidney, lung) lead to the AAV phenotypic disease patterns?

Hydralazine - known culprit of drug-induced AAV
How does hydral (H) AAV differ from primary (1) AAV?
💥 High dual positivity MPO/PR3
💥 DAH / pleuritis more common in H-AAV
💥 ENT, constitutional, nervous, ILD in 1-AAV
💥 More 6mo remission in H-AAV

SELECT-GCA suggests JAKis may be the new kid on the block
Clinicians treating giant cell arteritis (GCA) have long had to contend with a disappointingly limited selection of drugs from which to select.

PET for GCA
Delayed imaging at 180 min improve dx performance for pts on GCs
Optimal PET w/in 3 days of GC, most patients unable to do w/in that window
Delay has sensitivity 92% even on prednisone - may be good tool for pts unable to get early PET/CT
