Blood proteins related to immunoregulation or cellular junctions reveal distinct biological profiles associated with the risk of short-term versus mid/long-term relapse in Crohn’s Disease patients stopping infliximab
In Crohn’s Disease (CD), anti-tumour necrosis factor α (TNFα) therapy can induce mucosal healing and stable remission. When this objective is achieved, treatment de-escalation may be considered for safety, economic and patient preference purposes. Indeed, chronic exposure to anti-TNFα has been linked to serious complications (e.g. lymphoma, infections, melanoma and non-melanoma skin cancers) [1–4], and this treatment is a burden for the healthcare system [5]. On the other hand, around 50% of CD patients relapse 1–2 years after stopping anti-TNFα [6]. Thus, this strategy cannot be proposed to every patient in remission; rather, decisions should be made on an individualised basis [6].
