Metabolic abnormalities in rheumatoid arthritis patients with comorbid diabetes mellitus

The metabolic characteristics of rheumatoid arthritis (RA) or diabetes mellitus (DM) have been studied, but the metabolic abnormalities of RA patients complicated with DM are not completely understood. Therefore, we recruited RA patients with DM to investigate the metabolic abnormalities in these patients. We collected data of RA patients with DM and age- and sex-matched RA and DM patients from Changhai Hospital's electronic medical record system. Data of demographically matched healthy controls were also collected from the health management system of the Hangzhou Sanatorium of People's Liberation Army. Blood pressure, uric acid, glucose, and lipid levels were compared. The clinical data of RA with DM (n = 104), DM (n = 100), and RA (n = 100) patients and healthy controls (n = 100) were collected and compared. RA patients with DM had higher blood pressure and lower high-density lipoprotein cholesterol levels than the other three groups, a higher triglycerides (TG) level than healthy controls and RA patients, and a lower TG level than DM patients. RA patients with DM exhibited a relatively high proportion of metabolic abnormalities based on existing standards. Our study examined metabolic abnormalities in RA patients with DM for the first time, and our results suggest that clinicians should pay more attention to the metabolic abnormalities of RA patients with DM.
