Serum vitamin D levels in patients with systemic lupus erythematosus and their relationship with disease activity / 实用医学杂志

ABSTRACT

Objective To detect the serum 25- OH-D levels in patients with systemic lupus erythematosus (SLE) and investigate the function of vitamin D in the pathogenesis of SLE. Methods Eighty SLE patients including 40 healthy donors and 40 RA (rheumatoid arthritis) patients were enrolled in this study. Serum 25-OH-D levels were detected with ECL method. Results (1)Serum 25-OH-D levels in patients with active SLE were lower than those with inactive SLE patients and healthy controls. (2)Serum 25-OH-D levels were negatively correlated with SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) scores (r = -0.45,P < 0.01) and 24-hours urinary protein excretion (r = -0.32,P < 0.05). Conclusion Serum 25-OH-D levels in SLE patients decrease and have close relationship with disease activity and renal lesions.
