Type 2 diabetes mellitus (T2DM) patients are likely to develop kidney disease. The need to identify more accessible and cheaper diagnostic biomarkers cannot be overemphasized. This study investigated the ability of serum uric and uric acid to creatinine ratio in assessing the kidney function of T2DM patients and determined the relationship between serum uric acid to creatinine ratio and estimated glomerular filtration rate (eGFR).
One hundred and fifty-five (155) consented T2DM patients were recruited from the diabetes clinic of the Cape Coast Teaching hospital. Anthropometric variables and blood pressure were measured. Serum uric acid (SUA), serum creatinine and urine protein were estimated using standard protocols. Uric acid to creatinine ratio (UA:CR), eGFR were then calculated.
From the receiver operator characteristic (ROC) curve obtained, serum uric acid was found to be a better predictor of impaired renal function than UA:CR at p = 0.0001. The uric acid levels of participants in the fourth quartile of each category was found to be significant at p = 0.010 and can be used as indicators of kidney function in these participants. According to the odds ratio, the UA:CR will not be suitable to be used as an indicator of kidney function in any of the participants because their odds ratios were all less than 1. A total of 29(18.7 %) participants were found to have CKD with their eGFR falling below 60 ml/mins per 1.73 m. A significant positive relationship was found between serum uric acid and the staging of CKD according to eGFR whiles a negative relationship was found with UA:CR and CKD ( < 0.0001).
Serum uric acid is a better indicator of renal impairment (eGFR < 60 ml/mins per 1.73 m) than UA:CR in patients with type 2 diabetes mellitus.
2型糖尿病(T2DM)患者容易患肾脏疾病。强调识别更易获取且更便宜的诊断生物标志物的必要性再怎么强调也不为过。本研究调查了血清尿酸及尿酸与肌酐比值评估T2DM患者肾功能的能力,并确定了血清尿酸与肌酐比值和估计肾小球滤过率(eGFR)之间的关系。
从海岸角教学医院糖尿病诊所招募了155名同意参与的T2DM患者。测量了人体测量变量和血压。使用标准方案估算血清尿酸(SUA)、血清肌酐和尿蛋白。然后计算尿酸与肌酐比值(UA:CR)、eGFR。
从获得的受试者工作特征(ROC)曲线来看,血清尿酸在预测肾功能受损方面比UA:CR更好,p = 0.0001。发现每个类别第四四分位数参与者的尿酸水平在p = 0.010时具有显著性,可作为这些参与者肾功能的指标。根据优势比,UA:CR不适合用作任何参与者的肾功能指标,因为它们的优势比均小于1。共发现有CKD的参与者29名(18.7%),其eGFR低于60 ml/分钟/1.73平方米。根据eGFR,血清尿酸与CKD分期之间存在显著正相关,而UA:CR与CKD之间存在负相关(<0.0001)。
在2型糖尿病患者中,血清尿酸比UA:CR是肾功能损害(eGFR < 60 ml/分钟/1.73平方米)的更好指标。
