Dyslipidaemia is common in patients with rheumatoid arthritis (RA) appearing both early and advanced stages of the disease. A retrospective study was designed to explore the clinical significance of high density lipoprotein (HDL) in Chinese patients with RA. Serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were compared between RA patients complicated with osteoporosis (OP) and without OP, using logistic regression and ROC curve to analyse the association of HDL with OP. C reactive protein (CRP), erythrocyte sedimentation rate(ESR), rheumatoid factor(RF), anti-cyclic citrulline polypeptide antibody (anti-CCP), 28 joints disease activity(DAS28) as well as organ involvement rates were then analysed between RA patients with different HDL levels. Serum levels of HDL were 1.2 ± 0.3 mmol/L in RA patients complicated with OP, significantly higher than those without OP; HDL was a risk factor for RA patients with OP, OR (95% CI) being 10.2 (4.5-23.0) after adjusting for gender, age and body mass index(BMI). RA patients with HDL ≤ 1.04 mmol/L had significantly higher levels of CRP, ESR, DAS28 and cardiovascular disease (CVD) incidence rate, yet OP incidence rate was lower. HDL was a predictor of RA-related OP, indicating potential value as predictor of disease complications in RA patients.
