Acute Fatty Liver of Pregnancy: A Retrospective Analysis of 56 Cases.

Abstract：

BACKGROUND:Acute fatty liver of pregnancy (AFLP) is a rare but life-threatening complication occurring in the third trimester. It is often fatal to both mother and fetus. The complicated clinical manifestations as well as an insufficient understanding of the disease make the precise diagnosis and effective treatment of AFLP challenging. A full understanding of the risk factors, clinical features, and test findings of AFLP is critical for its timely diagnosis and treatment. METHODS:We performed a retrospective study of 56 patients with AFLP between June 2008 and July 2013. We analyzed the clinical features, laboratory results, perioperative management, and patient outcomes. RESULTS:The initial symptoms varied considerably, with nausea and vomiting (13/56, 23%) being the most common. Liver-function indexes were remarkable, including elevated levels of serum alanine aminotransferase (262.16 ± 281.71 U/L), aspartate aminotransferase (260.98 ± 237.91 U/L), lactic dehydrogenase (1011.76 ± 530.34 U/L), and direct bilirubin (85.59 ± 90.02 μmol/L). Coagulation disorders were indicated by abnormal levels of fibrinogen (245.95 ± 186.11 mg/dL), D-dimer (2.46 ± 4.01 mg/L), and fibrin degradation products (43.62 ± 48.71 mg/L). The main maternal complications were hypoproteinemia (75%), coagulopathy (54%), and acute renal failure (39%). Multivariate logistic regression analysis identified prothrombin time (PT; odds ratio [OR] = 1.558, 95% confidence interval [CI] =1.248-1.946, PORCIP= 0.009) as risk factors. The perinatal infant death rate was related to gestational age at delivery (ORCI PORCI PORCI PConclusions: Nausea and vomiting may be the most common symptoms of AFLP. Indexes of liver dysfunction and coagulation disorders should also be considered. PT and INR are risk factors for fatal complications in patients with AFLP, and perinatal mortality is linked to the level of fibrin degradation products. Timely delivery is crucial to controlling the development of AFLP.
