Its traditional therapy is not very effective in facilitating hepatic recovery. The safety and effect of plasma exchange (PE)in combination with continuous renal replacement therapy(CRRT) (PE+CRRT) for AFLP still needs evaluation.METHODS: Five AFLP patients with hepatic encephalopathy and renal failure were subjected to PE+CRRT in our department from 2007 to 2012. Their symptoms, physical signs and results were observed, and all relevant laboratory tests were compared before and after PE+CRRT.RESULTS: All the 5 patients were well tolerated to the therapy. Four of them responded to the treatment and showed improvement in clinical symptoms/signs and laboratory results and they were cured and discharged home after the treatment One patient succeeded in bridging to transplantation for slowing down hepatic failure and its complications process after2 treatment sessions. Intensive care unit stay and hospital stay were 9.4 (range 5-18) and 25.0 days (range 11-42), respectively.CONCLUSION: PE+CRRT is safe and effective and should be used immediately at the onset of hepatic encephalopathy and/or renal failure in patients with AFLP.展开更多

Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.展开更多

The rarity of this situation along with nonspecific symptoms makes it difficult to diagnose and thus causes catastrophic events. Biochemical parameters are required to diagnose this condition and differentiate it from other life threatening causes of pregnancy like HELLP syndrome and Preeclampsia. To avoid complications it is imperative to diagnose this condition at the earliest by doing blood test investigation and symptomatic management and delivery. We present a case in our hospital which came to urgent care with nonspecific symptoms and was diagnosed on blood tests and managed promptly and thus averted a catastrophic event.展开更多

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 AF LP 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 offibrinogen (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, P= 0.016) and international normalized ratio (INR; OR = 40.034, 95% CI= 2.517-636.693, P = 0.009) as risk factors. The perinatal infant death rate was related to gestational age at delivery (OR = 1.298, 95% CI- 1.040-1.618, P = 0.021), direct bilirubin (OR = 1.05, 95% CI = 1.008 1.094, P = 0.020), and fibrin degradation products (OR - 0.973, 95% CI = 0.950 0.996, P= 0.021). Conclusions: 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 AFLR展开更多

Methods Eight cases of AFLP seen in our hospital during the past three years were studied retrospectively. Symptoms, laboratory findings, timing of liver biopsy, and maternal and fetus outcome were assessed. Results The mean gestational age at onset was 34 ± 2 weeks. All cases were primigravida. In the early stages, all patients presented malaise, nausea, vomiting and epigastric distress followed by jaundice in the third trimester of pregnancy. Laboratory findings:all had raised transaminases and serum bilirubin (32 .5 - 510. 8 umol/L), hypoalbuminemia (22 .4 -30.0 g/L ), hypofibrinogenemia (< 180 mg/dl ),prolonged prothrombin time and prolonged partial thromboplastin time. Maternal complication included hepatic encephalopathy (6 cases ), ascites (6 ),hypoglycemia (5), hematemesis (2), and postpartum hemorrhage (5) and preeclampsia (4). Emergency cesarean section was performed in 3 cases. One mother died of fulminant hepatic failure and the others survived. There was no fetus death. Liver biopsy was done on the 5th to 15th postpartum day in 8 cases. Conclusion With increasing awareness, especially in the early recognition of milder cases, and prompt progressive management including early termination of pregnancy by cesarean section and large dose infusion of fresh frozen plasma and albumin alternately, the prognosis of AFLP can be improved.展开更多
