Interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) have important functions in injury and repair processes of glomerular intrinsic cells. A study was conducted to analyze the urinary VEGF/creatinine (CR) and IL-6/CR levels in simple hematuria patients after excluding the interference of creatinine. We aimed to investigate the function and relationships of the above indices in the glomerular pathological injury process, and to elaborate the values of urinary VEGF and IL-6 changes in the diagnosis of asymptomatic hematuria or hematuria with proteinuria.
A total of 121 renal hematuria patients diagnosed by clinical and laboratory tests were included as research subjects. The midstream fresh morning urine was collected on the day renal biopsy was performed.
The IL-6/CR value of the group III was significantly greater than in group I (Z=−2.478, P<0.05), with a statistically significant difference between these 2 groups. The VEGF/CR value of group III was significantly greater than in group II ( P<0.01). Compared with group I, the VEGF/CR of group III was significantly greater (Z=−4.65, P<0.01), with a statistically significant difference.
