We read with great interest the study by Gaujoux et al, who described a whole blood marker for anti-tumour necrosis factor (TNF) responsiveness in patients with Crohn's disease (CD). The availability of anti-TNF agents dramatically changed therapeutic strategies for patients with CD. However, an overall non-response rate of 30% has been observed, and, together with the approval of new classes of biological agents with a different mode of action, clearly indicates the need for predictive biomarkers. Gaujoux et al identified triggering receptor expressed on myeloid cells 1 (TREM1) expression in whole blood as a biomarker for anti-TNF (non)response (higher expression in responders).1 In inflamed colonic tissue, TREM1 expression is also decreased in future infliximab responders.1 2 TREM-1 is known to amplify inflammation, whereas TREM-1 inhibition in vivo attenuates colitis by modulating autophagy and endoplasmic reticulum (ER) stress.3
We first measured serum TREM-1 (sTREM-1)...
