Abstract:
Objective To observe the variation tendency of laboratory indexes after delivery in pregnant women with acute fatty liver of pregnancy (AFLP) and the effects of plasma exchange (PE) on the patients prognoses and those parameters. Methods The data of 37 patients with AFLP admitted to the Department of Intensive Care Unit (ICU) of Anhui Provincial Hospital from January 2009 to June 2017 were retrospectively analyzed and the authors tried to clarify the natural course of AFLP; all the selected patients met the Swansea criteria of the AFLP diagnosis. The patients were divided into a PE group (9 cases) and a non-PE group (28 cases) according to whether they were treated with PE or not. At the same time, the effects of PE on liver function and coagulation parameters in the patients were analyzed. Results The most common clinical symptoms of 37 AFLP patients were as follows: nausea and vomiting (21 cases, incidence 56.8%), jaundice (21 cases, 56.8%), upper abdominal pain (14 cases, 37.8%), and more than 90% of patients had more than one symptom. All 37 patients with AFLP had abnormal liver function, their differences in the severity degrees were great, and the level of aspartate aminotransferase (AST) was (271.65±265.90) U/L;the levels of creatinine (SCr) of 72.9% patients (27 cases) were more than 140 mmol/L; the prothrombin times (PT) of 72.97% patients (27 cases) were more than 15 seconds; all patients had received blood product transfusion. Liver function and blood coagulation parameters mostly returned to normal within 1 week after delivery: AST rapidly decreased on the 1 - 2 days after delivery and then continued to decrease; all the cholesterol levels in the two groups decreased to the lowest levels within 3 - 4 days after delivery and then began to rise; the total bilirubin (TBil) levels kept on basically unchanging after delivery; in the patients with levels of platelet counts (PLT) on admission ≥ 150×109/L, on the second day after delivery, their counts returned to approximately 100×109/L, while in patients with PLT < 150×109/L on admission, on the sixth day after delivery, the counts began to slowly increase to about 100×109/L; the patients with fibrinogen (Fib) levels > 1.5 g/L on admission, the levels slightly decreased 2 days before delivery, then gradually recovered and stabilized after delivery, while the patients with Fib < 1.5 g/L, the levels began to rise slowly on the second day after delivery; prothrombin time (PT) and activated partial thromboplastin time (APTT) were basically return to the normal reference ranges on the fifth day after delivery. The PE therapy could significantly improve the patients' laboratory indexes: the levels of AST, TBil, PLT, PT were significant lower immediately and on the second day after PE compared with those levels before the PE [AST (U/L): 197 (114, 383), 116 (65, 311) vs. 239 (125, 430), TBil (μmol/L):109 (67, 126), 125 (103, 178) vs. 164 (99, 198), PLT (×109/L): 96.44±33.10, 89.89±33.03 vs. 126.22±40.83, PT (s): 17.82±5.93, 18.36±3.19 vs. 22.67±8.44, all P < 0.05]. Conclusion After terminating the delivery in time for about one week, the AFLP patients' various indexes may basically return to normal; PE therapy can improve the patients' liver function and coagulation indexes.
