A very small study presented at ACR18 looking at tocilizumab monotherapy in patients with a new diagnosis of giant cell arteritis has nevertheless given hope to the tantalising idea that some GCA patients might achieve drug-free remission without steroids, although broader data are required.
Interesting data on PET/CT in GCA from Dr Sammel from Sydney incl some pickup of cranial GCA. Not replacing TABx totally but ?similar to MRI/USS with the plus of picking up infx/Ca, with same radiation as full CT. Aussies doing well with PET/CT @drceowen! #ACR18 ABSTL15 @RheumNow pic.twitter.com/omhLbS1xbN

#ACR18 Late Breaking:#L15 Anthony Sammel – PET/CT vs TAB for suspected GCA. PET 92% sens, 85% spec. (NB 3/7 false+ were clinically diagnosed with GCA). NPV 98%. Kappa 0.65. Including 4 vessels improves PET performance.
Great data, GCA Dx remains a difficult art.@RheumNow pic.twitter.com/eAA3QNYBfd
