Abstract
(en) TO THE EDITOR, I read with great interest the article by Garvey et al. They mentioned that treatment with tocilizumab induced a direct inhibition of the acute phase response, and thus C-reactive protein levels are difficult to interpret. This is why identifying active disease or relapse is a challenge in these patients. 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has been proposed as a useful tool to assess response and relapse. However, several studies reported that a complete normalization of PET/CT activity occurred in less than 30% of patients while they are in clinical remission. [...]
