Objective

To explore the clinical characteristics and perinatal management of pregnant women with acute fatty liver of pregnancy (AFLP).

Methods

Twenty-six pregnant women with AFLP who were admitted to Yantai Yuhuangding Hospital from January 2013 to January 2023 were selected as research subjects. Among these 26 pregnant women with AFLP, there were 9, 6, 7, 5 and 3 cases with infection, disseminated intravascular coagulation (DIC), acute kidney failure (AKF), multiple organ dysfunction syndrome (MODS), and hematoma, respectively, and they were included in the study groups 1-5 (n=9, 6, 7, 5, 3), and the rest were included in control group 1-5 (n=17, 20, 19, 21, 23). The general clinical data, laboratory examination results, complications, treatment plans and other clinical data of 26 pregnant women with AFLP were retrospectively collected, and were compared by independent-samples t test and Wilcoxon rank sum test between different complication groups and control groups. The procedures followed in this study were in accordance with the regulations of the Ethics Committee of Yantai Yuhuangding Hospital, and was approved by the Ethics Committee (Approval No. 2024-438).

Results

①Among 26 pregnant women with AFLP, the main clinical manifestations were nausea (18 cases, 69.2%), xanthochromia (16 cases, 61.5%), vomiting (12 cases, 46.2%), abdominal discomfort (12 cases, 46.2%), and poor appetite (9 cases, 34.6%). There were 21 cases of primipara (80.8%), 6 cases of twin pregnancy (23.1%) and 25 cases of cesarean section delivery (96.2%). ②The level of serum total bilirubin (TBIL) in study group 1 was significantly higher than that in control group 1, and the difference was statistically significant (Z=-2.29, P=0.022). The prothrombin time (PT), activated partial thromboplastin time (APPT) and D-dimer level in study group 2 were significantly longer and higher than those in control group 2, while fibrinogen (Fib) level in study group 2 was significantly lower than that in control group 2, and all the differences were statistically significant (Z=-2.50, P=0.013; t=4.88, P=0.001; t=2.08, P=0.048; Z=-3.23, P=0.001). The levels of urea and creatinine in study group 3 were significantly higher than those in control group 3, and the differences were statistically significant (Z=-2.46, P=0.014; t=1.78, P=0.001). The levels of urea and creatinine in study group 4 were significantly higher than those in control group 4, and the level of Fib in study group 4 was significantly lower than that in control group 4, and the differences were statistically significant (Z=-2.28, P=0.004; t=4.33, P=0.001; Z=-1.99, P=0.047). PT, APTT, serum TBIL level, plasma transfusion volume and coagulation function recovery time in study group 5 were significantly longer or higher than those in control group 5, and the differences were statistically significant (Z=-1.97, -2.21, -1.97, -2.07, -2.20; P=0.049, 0.027, 0.049, 0.039, 0.028). ③All 26 cases (100.0%) of pregnant women were treated with liver protection and infection prevention. And 23 cases (88.5%) were treated with correction of coagulation therapy, 9 cases (34.6%) were treated with anti-infective therapy, 8 cases (30.8%) were treated with correction of electrolyte therapy, 6 cases (23.1%) were transferred to intensive care unit (ICU), and 2 cases (7.7%) were treated with hemofiltration. Thoracic and abdominal puncture drainage was performed on 2 cases (7.7%), plasma exchange was performed on 2 cases (7.7%), and removal of abdominal wall hematoma was performed on 1 case (3.8%). 26 cases of pregnant women were cured and discharged from hospital after treatment. ④Among the 32 newborns of 26 AFLP pregnant women, 2 cases were intrauterine death, and the other 30 cases of live-born infants were transferred to neonatology department and discharged successfully after treatment.

Conclusions

The clinical manifestations of AFLP pregnant women are mostly gastrointestinal symptoms. Early diagnosis of AFLP, early termination of pregnancy and management by multi-disciplinary team (MDT) in obstetrics are the key to rescue AFLP.
