Abstract

Dyslipidaemia and inflammation are closely interconnected in their contribution to atherosclerosis. In fact, low-density lipoprotein (LDL)-lowering drugs have anti-inflammatory effects. The Canakinumab Antiinflammatory Thrombosis Outcome Study (CANTOS) has shown that interleukin (IL)-1 blockade reduces the incidence of cardiovascular events in patients with previous myocardial infarction and C-reactive protein levels >2mg/L. These data confirm the connection between lipids and inflammation, as lipids activate the Nod-like receptor protein 3 inflammasome that leads to IL-1 activation. LDL-lowering drugs are the foundation of cardiovascular prevention. Now, the CANTOS trial demonstrates that combining them with IL-1 blockade further decreases the incidence of cardiovascular events. However, both therapies are not at the same level, given the large evidence showing that LDL-lowering drugs reduce cardiovascular risk as opposed to only one randomized trial of IL-1 blockade. In addition, IL-1 blockade has only been studied in patients with C-reactive protein >2mg/L, while the benefit of LDL-lowering is not restricted to these patients. Also, lipid-lowering drugs are not harmful even at very low ranges of LDL, while anti-inflammatory therapies may confer a higher risk of developing fatal infections and sepsis. In the future, more clinical trials are needed to explore whether targeting other inflammatory molecules, both related and unrelated to the IL-1 pathway, reduces the cardiovascular risk. In this regard, the ongoing trials with methotrexate and colchicine may clarify whether the cardiovascular benefit of IL-1 blockade extends to other anti-inflammatory mechanisms. A positive result would represent a major change in the future treatment of atherosclerosis.
