标题：Using advanced oxidation protein products and ischaemia-modified albumin to monitor oxidative stress levels in patients with drug-induced liver injury
摘要：Increased oxidative stress levels play a key role in idiosyncratic drug-induced liver injury (DILI) pathogenesis. To investigated whether advanced oxidation protein products (AOPPs) and ischaemia-modified albumin (IMA) can be used to monitor oxidative stress in DILI patients and to assess disease severity. We performed spectrophotometric assays to assess AOPPs and IMA in 68 DILI patients with severity grade 0–2 (non-severe group), 60 with severity grade 3–5 (severe group), and 38 healthy controls. The results showed that baseline AOPPs and IMA serum levels and AOPPs/albumin and IMA/albumin ratios were significantly higher in DILI patients than in healthy controls. Besides, in comparison to the non-severe group, the severe group showed higher baseline AOPPs and IMA serum levels and AOPPs/albumin and IMA/albumin ratios. AOPPs and IMA serum levels and AOPPs/albumin and IMA/albumin ratios decreased after treatment in both patient groups. Combining the correlation analysis and areas under the receiver operating curve (AUROCs) analysis results, that IMA outperformed to be one is the most reliable marker to assess disease severity of DILI. Our findings indicated that AOPPs and IMA can serve as key biomarkers for monitoring oxidative stress levels in DILI patients and can indicate disease severity. The IMA outperformed to be one of the most reliable oxidative stress biomarkers to assess disease severity of DILI.
