Investigating the Clinical Value of Novel Kidney Injury Inflammatory Biomarkers in Snakebite Victims

ABSTRACT

Objective: The expression of vascular endothelial growth factor-A (VEGF-A) in snakebite patients, its value in patient prognosis and the correlation of VEGF-A with renal function were analysed. Methods: A total of 124 snakebite patients admitted from January 2019 to January 2021 were retrospectively analysed and included in the observation group, and 40 healthy individuals who underwent physical examination in the same hospital within the same period were included in the control group. The t-test was used in analysing differences between the serum VEGF-A levels of the observation and control groups and changes in VEGF-A and renal function indices before and after treatment in the observation group. The effects of treatment on each patient in the observation group were evaluated, and the patients were divided into improved and unimproved groups according to the post-treatment condition. The predictive value of VEGF-A and renal function indices in patients in the improved and unimproved groups and their efficacy for snakebite patients were analysed through receiver operating characteristic (ROC) analysis. Finally, correlation analysis was used in evaluating the correlation between VEGF-A and renal function indices. Results: VEGF-A was significantly higher in patients in the observation group (339.66 ± 97.72 pg/mL) than in patients in the control group (52.41 ± 8.93 pg/mL; p < 0.001). VEGF-A and renal function indices in the serum of patients were significantly lower after treatment than those before treatment (p < 0.0001). According to efficacy, the patients were divided into improved group (n = 102) and unimproved group (n = 22). The pre-treatment VEGF-A levels were significantly lower in patients in the improved group (318.47 ± 90.80 pg/mL) than in patients in the unimproved group (437.88 ± 63.16 pg/mL; p < 0.001) (AU)
