CYP2E1 immunoglobulin G4 subclass antibodies after desflurane anesthesia

摘要

AIM: To investigate CYP2E1 IgG4 autoantibody levels and liver biochemical markers in adult patients after anesthesia with desflurane. METHODS: Forty patients who were > 18 years old and undergoing elective surgery under general anes-thesia with desflurane were studied. Alpha-glutathione-S-transferase(aGST) and IgG4 antibodies againstCYP2E1 were measured preoperatively and 96 h post-operatively, as well as complete blood count, prothrom-bin time(PT), activated partial thromboplastin time(aPTT), international normalized ratio(INR), aspartate aminotransferase(SGOT), alanine aminotransferase(SGPT), g-glutamyl-transpeptidase(gGT), alkaline phosphatase, total serum proteins, albumin and bili-rubin. A separate group of 8 patients who received re-gional anesthesia was also studied for calibration of the methodology used for CYP2E1 IgG4 and aGST measure-ments. Student's t-test and the Mann-Whitney U test were used for comparison of the continuous variables, and Fisher's exact test was used for the categorical variables. All tests were two-tailed, with statistical sig-nificance set as P 0.1). The mean aGST differences were statistically elevated in men by 2.15 ng/mL compared to women when adjusted for BMI, duration of anesthe-sia, number of times anesthesia was administered pre-viously and length of hospital stay. No significant dif-ference was observed between patients who received desflurane and those who received regional anesthesia at any time point.CONCLUSION: There was no difference in CYP2E1 IgG4 or aGST levels after desflurane exposure; furtherresearch is required to investigate their role in desflu-rane-induced liver injury.
