AIM: To determine the predictive ability of serum thiol-disulphide levels for contrast medium-associated acute kidney injury (CA-AKI) after endovascular treatment (EVT) of peripheral arterial disease (PAD) and evaluate the efficacy of intravenous N-acetylcysteine (NAC) in preventing CA-AKI.
MATERIAL AND METHODS: This double-blind, randomised controlled study included 85 consecutive adult patients who underwent EVT for PAD. Patients were divided into NAC negative (NAC-) and positive (NAC+) groups. While the NAC- group received only 500 ml saline, the NAC + group received 500 ml saline plus intravenous 600 mg NAC before the procedure. Intra- and intergroup patient characteristics, procedural details, preoperative thiol-disulphide levels, and ischaemia-modified albumin (IMA) levels were recorded.
RESULTS: There was a significant difference between NAC- and NAC + groups regarding native thiol, total thiol, disulphide/native thiol ratio (D/NT), and disulphide/total thiol ratio (D/TT). There was also a significant difference between the NAC- (33.3%) and NAC+ (13%) groups in CA-AKI development. Logistic regression analysis showed that the D/TT (OR 2.463) and D/NT (OR 2.121) were the most influential parameters for CA-AKI development. In the receiver operating characteristic (ROC) curve analysis, the sensitivity of native thiol to detect the development of CA-AKI was 89.1%. The negative predictive values of native thiol and total thiol were 95.6% and 94.1%, respectively.
CONCLUSION: The serum thiol-disulphide level can be used as a biomarker to detect CA-AKI development and reveal patients with a low risk for CA-AKI development before EVT of PAD. Furthermore, thiol-disulphide levels allow for the indirect quantitative monitoring of NAC. Preprocedural intravenous NAC administration significantly inhibits CA-AKI development.
