Abstract:
Objective:To investigate the effect of hyperuricemia on acute kidney injury in sepsis patients.Methods:It is a retrospective cohort study of 459 adult sepsis patients who were admitted to the Department of Intensive Care Unit (ICU) of the First Affiliated Hospital of Guangxi Medical University from March 2014 to June 2019, and the Second Affiliated Hospital of Guangxi Medical University from January 2017 to June 2019. The patients were divided into the hyperuricemia group and the non-hyperuricemia group according to the first serum uric acid level within 24 h after ICU admission, and the incidence of AKI within 7 days after ICU admission was compared between the two groups. The effect of hyperuricemia on sepsis-associated AKI was analyzed by univariate analysis and binary logistic regression analysis.Results:Among the 459 sepsis patients, 81 patients (17.6%) had hyperuricemia, and 127 patients (27.7%) had AKI. The incidence of AKI in the hyperuricemia group and the non-hyperuricemia group were 60.5% (49/81) and 20.6% (78/378), respectively, which showed significantly statistical difference ( χ2=52.954, P<0.01). After adjusting for gender, associated diseases (diabetes, coronary heart disease), sequential organ failure score (SOFA) on the day of ICU admission, the use of diuretics within one week before and after ICU admission, invasive mechanical ventilation, basal renal function, lactic acid, and procalcitonin, binary logistic regression analysis showed that hyperuricemia was an independent risk factor for AKI in sepsis patients ( OR=5.091, 95% CI: 2.768-9.362, P<0.01); For every 1 mg/dL increase in serum uric acid in sepsis patients, the risk of developing AKI increased by 28.4% ( OR=1.284, 95% CI: 1.165-1.414, P<0.01). Conclusions:AKI is a common complication in sepsis patients admitted to ICU, and hyperuricemia is an independent risk factor for AKI in sepsis patients.
