Résumé
Objective:To explore the predictive value of serum adiponectin (APN) in parenteral nutrition associated cholestasis (PNAC) in premature infants.Methods:A retrospective analysis was conducted on the clinical data of 85 premature infants treated with PN (parenteral nutrition) at the Yiyang Central Hospital from January to December 2021. According to whether PNAC occurred during hospitalization, the infants were divided into 34 PNAC group and 51 non PNAC group. A comparison was made between the PNAC group and the non PNAC group. The serum APN levels in children of different gestational ages in the PNAC group were analyzed, and the risk factors for PNAC in premature infants were analyzed. The predictive value of serum APN in premature PNAC was analyzed.Results:The serum APN levels in the PNAC group were lower than those in the non PNAC group at weeks 1, 3, and 5, and the difference was statistically significant (all P<0.01). The serum APN levels in children with gestational age<34 weeks in the PNAC group were lower than those in children with gestational age≥34 weeks at 1, 3, and 5 weeks, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that gestational age, birth weight, sepsis, fasting time, duration of PN, accumulation of fat emulsion, initial amount of amino acids, and accumulation of amino acids were all risk factors for PNAC in premature infants (all P<0.05). The area under the curve (AUC) of serum APN for predicting PNAC in premature infants was 0.814(95% CI: 0.722-0.906), with a sensitivity of 0.69, specificity of 0.88, and a cutoff value of 13.28 mg/L. Conclusions:Serum APN has a high predictive value for the occurrence of PNAC in premature infants, and should be closely monitored in clinical practice.
