Association between atherogenic index of plasma and renal function impairment in patients with gout / 中华内分泌代谢杂志

ABSTRACT

Objective@#To study the relationship between atherogenic index of plasma (AIP)and renal impairment in male patients with gout.@*Methods@#A retrospective analysis of 821 male subjects was conducted to measure the relevant biochemical indicators and to calculate the AIP, endogenous creatinine-clearance rate (Ccr), and estimated glomerular filtration rate (eGFR). EpiData 3.1 software was used for data entry, SPSS21.0 was used for statistical analysis, and GraphPad Prism 6.0 software was used for charts.@*Results@#Compared with control group, AIP, serum uric acid, triglyceride in gout group were significantly higher (all P<0.01), while eGFR and high density lipoprotein-cholesterol were significantly lower (both P<0.05). The composition ratio of renal function impairment in gout group was significantly higher (P<0.01). With the increase of AIP level, eGFR level decreased and serum creatinine level increased, but the overall difference was not statistically significant (P>0.05), while Ccr and serum uric acid levels gradually increased (P<0.05). Logistic regression analysis after adjusting for various confounding factors showed that AIP, triglyceride, and serum uric acid were risk factors for renal function damage in patients with gout (P<0.05), the relevant risk were 7.030, 1.291, 1.004 respectively. After adjusting confounding factors, the associations between triglyceride, serum uric acid and renal function injury risk changed little, while AIP showed more evident, the OR value increased from 2.629 to 6.265 and 7.030.@*Conclusions@#(1)AIP is closely related to the renal function damage of patients with gout. After adjusting various confounding factors, AIP can better reflect the renal function damage than other indicators, which is of great significance to predict the renal function damage of patients with gout. (2)That patients with gout with high uric acid level may suffer from renal atherosclerosis and have a higher risk of renal impairment. (3)Dynamic observation of AIP in gout patients is helpful for early identification of the risk of renal failure in such patients.
