Hyperuricemia is an independent risk factor for renal pathological damage and poor prognosis in lupus nephritis patients / 中南大学学报(医学版)

To explore the correlation between hyperuricemia and renal damage in patients with lupus nephritis (LN).
 Methods: The data for clinical features, laboratory and renal pathological examination were collected from 177 renal biopsy-proven LN patients with or without hyperuricemia and were retrospectively analyzed to determine the correlation between serum uric acid and renal damage.
 Results: LN patients with hyperuricemia group had higher rate of hypertension and higher level of blood urea nitrogen and serum creatinine while lower estimated glomerular filtration rate (eGFR) and lower positive rate of anti-U1RNP antibody (P<0.05). In the LN patients with hyperuricemia group, renal pathological scores, including acitive index, chronic index and tubulointerstitial lesions, were higher than those in the LN patients without hyperuricemia group (P<0.05). The level of serum uric acid was positively correlated with serum creatinine, renal pathological classification and renal pathological scores while negatively correlated with eGFR (P<0.05).
 Conclusion: LN patients with hyperuricemia are associated with more serious renal damage. Hyperuricemia is an important predictor for poor prognosis in patients with LN.

Association between elevated visfatin and carotid atherosclerosis in patients with chronic kidney disease / 中南大学学报(医学版)

OBJECTIVE@#To determine the levels of visfatin in patients with chronic kidney disease (CKD) and to explore the relationship between visfatin levels and caroid atherosclerosis in CKD patients.@*METHODS@#A total of 180 CKD patients (102 non-dialyzed patients and 78 dialysis patients) and 42 healthy subjects enrolled in this study. The serum levels of visfatin, IL-6, and high sensitive C-reactive protein (hsCRP) were measured by ELISA. Common carotid arteries intima-media thickness (CCA-IMT), cross-sectional calculated intima-media thickness (c IMT) area and atherosclerotic plaque were detected by non-invasive high-resolution B-mode ultrasonography.@*RESULTS@#The serum levels of visfatin, IL-6 and hsCRP were significantly increased in CKD patients compared with age matched healthy subjects (P<0.01). The serum levels of visfatin, IL-6 and hsCRP in the dialyzed patients were significantly higher than those in non-dialyzed patients (P<0.05). Visfatin levels increased with the progression of renal dysfunction and inversely related to creatinine clearance (Ccr) in non-dialyzed patients (r=-0.415, P<0.05). Patients with carotid artery plaques showed significantly higher levels of visfatin[(34.22±7.96) ng/mL)] compared with those without plaques [(28.24±6.18) ng/mL, P<0.05]. The serum levels of visfatin were closely correlated with IL-6 (r=0.548, P<0.001), hsCRP (r=0.430, P<0.001), CCA-IMT (r=0.462, P<0.05), and c IMT area (r=0.411, P<0.05). After adjusting for GFR, age, gender, and other risk factors associated with atherosclerosis, multiple stepwise regression analysis showed that serum visfatin is a independent risk factor for CCA-IMT (β=0.433, P<0.01) and c IMT area (β=0.412, P<0.01).@*CONCLUSION@#The serum level of visfatin increase with the progression of CKD and should be considered to be a new risk factor for atherosclerosis in CKD.
