Idiopathic multicentric Castleman disease (iMCD) is a life-threatening inflammatory disease requiring immediate intervention, for which the recommended first-line therapy is the Interleukin-6 pathway inhibitor siltuximab. Authors here show that the change in levels of the chemokine CXCL13 shortly following the start of siltuximab treatment is predictive of response.
