Abstract:
Objective: To investigate the changes of serum Uric Acid (sUA), lipids and Cystatin C
(CysC) in primary gout patients, and to explore the clinical significance in gout patients.
Methods: sUA, CysC, high-sensitivity C-reactive Protein (hsCRP) and other biochemical parameters
were measured in 326 gout patient and 210 healthy control subjects, blood cell counts were
also detected. Clinical data were collected from gout patients.
Results: sUA, CysC, hsCRP, Body Mass Index (BMI), White Blood Cell (WBC) counts, neutrophil
Granulocyte (GR), Monocyte (Mo), Triglycerides (TG), plasma Total Cholesterol (TC), Very Low
Density Lipoprotein (VLDL), apolipoprotein B100 (apoB100), Blood Glucose (GLU), serum
Creatinine (sCr) and Urea Nitrogen (BUN) were significantly increased in gout patients compared
with HC subjects (P<0.01, respectively), while lymphocyte counts and High Density Lipoprotein-
Cholesterol (HDL-C) were significantly decreased in gout patients compared with HC subjects
(P<0.01, respectively). Positive correlations were observed between concentration of sUA and age,
TG, VLDL, sCr and CysC (P<0.05, respectively). While negative correlations were observed between
the concentration of sUA and HDL-C(P<0.01). Besides, Positive correlations were observed
between concentration of CysC and WBC, GR, Mo, apoA1, GLU, sCr, BUN, sUA, hsCRP
(P<0.05, respectively). While negative correlations were observed between the concentration of
CysC and TC, LDL-C(P<0.01, respectively).
Conclusions: Blood lipid profile changes in gout patients. Gout patients who suffer from lipid metabolism
disorder and vascular diseases might be associated with hyperuricemia, which leads to endothelial
cell damage and vascular smooth muscle cell proliferation. CysC might be a marker for
renal function damage and inflammation. Hyperuricemia is the risk factor of renal disorder in gout
patients.
