The mechanisms involved in inflammation related accelerated atherosclerosis and cardiovascular disease in rheumatoid arthritis (RA) require further study.1

Ghrelin, the endogenous ligand for the growth hormone secretagogue receptor, a gastric peptide playing a role in the appetite regulation, possesses anti-inflammatory properties.2 Otero et al showed reduced ghrelin plasma concentrations in patients with RA compared to controls.3

Improvement of insulin resistance in patients with severe disease who started anti-tumour necrosis factor (TNF)α therapy has been described previously.4 Additionally, we have reported a rapid improvement in endothelial dysfunction5 and insulin sensitivity6 following the infusion of the chimeric anti-TNFα/monoclonal antibody/infliximab in patients with RA with severe disease on periodical treatment with this drug. Moreover, inhibition of basal …
