Abstract
Abstract
Background
To assess the prevalence, risk factors, clinical characteristics of Acute fatty liver of pregnancy (AFLP) patients, and outcomes of AFLP patients treated with plasma exchange (PE).
Methods
We retrospectively reviewed the AFLP patients admitted to the First Affiliated Hospital of Xi’an Jiaotong University and Xijing Hospital of Air Force Medical University from January 2012 to May 2022. Final prediction model for death among AFLP by means of stepwise backward elimination with p value < 0.05. Patients treated with and without PE were compared by propensity-matched cohort study.
Results
Two hundred ninety eight patients with the diagnosis of AFLP, and finally 290 patients were enrolled in the cohort study, 50 of whom (17.2%) were dead. Compared with AFLP patients alive, the dead of patients were more likely to be combined encephalopathy (p < 0.01), postpartum hemorrhage (p < 0.01), and found significantly higher frequency of fetal distress (p = 0.04), fetal death (p < 0.01). we developed a predicted probability value and with an area under the receiver operating characteristics (ROC) curve of 0.94 (95%CI 0.87 to 1.00), indicating AFLP patients’ death. The patients treated with PE had a significantly lower 60-day mortality rate (OR 0.42, 95% CI 0.29 to 2.64, p = 0.04), and significantly shorter duration of hospital-free days at day 28 (p = 0.01).
Conclusions
In conclusion, our study indicated that liver function were risk factors for maternal mortality, and PE was a protective factor for maternal 60-day mortality and hospital-free days at day 28 in AFLP patients.
