Association of serum lipids with autoantibodies and inflammatory markers in rheumatoid arthritis patients

We studied the relationship between serum lipids and autoantibodies and inflammatory markers in rheumatoid arthritis (RA) patients to explore the effect of serum lipids on the diagnosis and judgment of disease activity in RA patients.Serum lipids including TCHO, TG, HDLC and LDLC and anti-CCP, RF, CRP, ESR of RA patients from May 2013 to August 2017 were retrospectively analyzed in the First Affiliated Hospital of Fujian Medical University.With the dilution factor increased, the concentrations of serum lipids and anti-CCP, CRP and RF showed the same downward trend, indicating that the detection methods of the above indicators were reasonable and would not be affected by hyperlipidemia. CRP and ESR levels were negatively correlated with HDLC concentration in male and female RA patients. However, the concentration of anti-CCP and RF were closely related to TG. In all the RA patients and female RA patients, the RF level was negatively correlated with the TG concentration. Moreover, with the TG concentration increased, the proportion of patients with high concentrations of anti-CCP levels decreased. In addition, in male RA patients, anti-CCP and ESR concentration increased with the increase of LDLC.The concentrations of HDLC, TG and LDLC were associated with the concentration of anti-CCP, RF, CRP and ESR in RA patients. Therefore, clinical diagnosis of RA and determination of disease activity should consider the impact of the concentration of serum lipids in order to make a reasonable judgment on the diagnosis of the disease.
