目的 總結肝移植治療慢性重癥肝炎急性肝衰竭的經驗，以期改善預后。 方法 回顧性分析我院施行的3例慢性重癥肝炎急性肝衰竭肝移植臨床資料。結果 2例男性，1例女性，術前均診斷為慢性重癥肝炎急性肝衰竭，肝功能Child分級均為C級，MELD評分分別為56.72、31.90及52.83，肝性腦病Ⅱ°～Ⅳ°，均合并肺部、腹腔感染，術前人工肝治療1～3次，均行背馱式肝移植，術后病例3停用免疫抑制劑11 d，病例2和病例3痊愈出院，病例1因嚴重感染繼發多器官功能衰竭死亡。結論 術前、術后人工肝支持改善內環境、術中及時補充凝血物質和術后有效控制感染是保證肝移植治療慢性重癥肝炎急性肝衰竭良好預后的關鍵措施。
目的:探討甲胎蛋白(AFP)含量與慢加急性肝衰竭預后的關系,進一步了解肝衰竭患者AFP含量的變化。方法:將回顧分析的65 例慢加急性肝衰竭患者根據最后治療結果分為存活組與死亡組,分析對比兩組在不同時間AFP含量的差異,同時觀察AFP含量與總膽紅素(TBil),凝血酶原活動度(PTA)的關系。結果:65 例患者中AFP含量高于正常者53 例(81.54%),存活組不同時期的AFP含量平均值均高于死亡組,有顯著差別(Plt;0.01)。AFP含量升高(≥300 IU/mL)主要分布在血清總膽紅素lt;510 μmoL/ mL,凝血酶原活動度gt;30 %患者中,隨AFP含量升高,病死率下降。結論:慢加急性肝衰竭患者血清AFP含量升高反應了肝細胞再生活躍,提示預后良好。
【Abstract】Objective To evaluate effect of artificial liver support system (ALSS) in liver failure and liver transplantation.Methods Forty-four patients with liver failure (including 12 undergoing liver transplantation) were treated with MARS or plasma exchange. The changes of toxic substances and cytokines in blood were detected before and after treatment. Results ALSS therapy achieved a remarkable improvement in clinical symptoms and physical signs. After ALSS treatment, there was a significant decrease in total bilirubin, total bile acid, alanine aminotransferase, creatinine, urea nitrogen, blood ammonia and endotoxin levels(P＜0.05); the levels of serum NO, TNF-α, IL-4 and IL-6 were significantly decreased(P＜0.05); there was no statistical change in erythrocytes, leukocytes and platelets. The survival rate of 30 liver failure patients caused by severe hepatitis B was 60.0%(18/30). Six patients with acute liver failure were successfully performed liver transplantation. Two patients in 6 with acute liver failure after liver transplantation survived. One patient in 2 with acute liver failure after pancreatoduodenectomy survived. Conclusion ALSS plays a positive role in treatment of liver failure by removing blood toxins, NO and cytokines. ALSS also plays a substitute role for liver failure patients who are waiting for liver transplantation.
ObjectiveTo summarize the changes and mechanism of related genes induced by stem cell therapy in acute-on-chronic liver failure (ACLF) in recent years, and in order to guide the clinical value of ACLF and curative effect evaluation. MethodsThrough searching Wanfang med, CNKI, Pubmed database and so on in recent years, the differentially expressed genes induced by stem cell therapy for ACLF in recent years was retrieved and the changes of related genes induced during the treatment process were discussed. ResultsBoth at home and abroad had reported that stem cell therapy in the process of ACLF caused mir-27b, TRAIL, and Tg737 genetic changes, some genetic changes had an fixed change trend. ConclusionsStem cells in the treatment of ACLF, cause mir-27b, TRAIL, Tg737 genetic changes, which can provides a new way and method for monitoring stem cell therapy ACLF.
Hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) has the characteristics of rapid progress and high mortality. Artificial liver support system (ALSS) is far superior to standard drug therapy in the treatment of such patients, and is widely used in emergency. ALSS is the use of external mechanical or biological devices to replace a part of the damaged liver function, divided into bioartificial, non-bioartificial liver and a combination of the two. At present, there is no unified sensitive prognostic index and recognized prognostic model for HBV-ACLF in artificial liver treatment. This paper reviews the research progress of prognosis evaluation of ALSS in the treatment of HBV-ACLF, in order to provide reference for clinicians and researchers
ObjectiveTo systematically review the efficacy and safety of plasma exchange (PE) versus routine medical therapy (RMT) for patients with chronic liver failure. MethodsWe electronically searched databases including PubMed, The Cochrane Library (Issue 7, 2014), CBM, CNKI, and VIP from inception to August 2014, to collect randomized controlled trials (RCTs) and clinical controlled trials (CCTs) of PE versus RMT for chronic liver failure patients. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.0 software. ResultsA total of 7 RCTs and 9 CCTs involving 1 632 patients (822 in the PE group and 810 in the RMT group) were included. The results of meta-analysis showed that:compared with the RMT group, the PE group had lower mortality rate (RCT:OR=0.24, 95%CI 0.13 to 0.43; CCT:OR=0.48, 95%CI 0.30 to 0.78) and higher total effective rate (RCT:OR=4.04, 95%CI 2.80 to 5.85; CCT:OR=3.45, 95%CI 2.11 to 5.64). Subgroup analysis based on the stage of liver failure showed that the PE group was superior to the RMT group in early- and intermediate-stage patients with liver failure in total effective rate (early stage:OR=4.78, 95%CI 1.87 to 12.23; intermediate stage:OR=4.43, 95%CI 1.77 to 11.08), but this difference was not found in advanced liver failure patients (OR=1.61, 95%CI 0.35 to 7.38). Seven studies reported 187 cases of adverse reactions (11.46%), and most of them were pruritus and urticaria. ConclusionCurrent evidence shows, compared with the routine medical therapy, the PE therapy could be effective to early- and intermediate-stage liver failure patients, but not be effective to advanced liver failure patients. In addition, patients who received the PE therapy have risks of adverse reactions which mainly are allergic reaction. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo introduce the basic principles of commonly used assessment methods for liver function reserve, and compare the advantages and disadvantages of various assessment methods, so as to provide a reference for hepatectomy of patients with hepatocellular carcinoma (HCC). MethodThe literature on evaluation methods of liver reserve function in patients with HCC at home and abroad in recent years was searched and summarized. ResultsFrom the results of literature review, the Child‐Pugh score and indocyanine green discharge test were the most commonly used to assess preoperative liver function reserve for patients with HCC. The application value of other examinations such as albumin-bilirubin score, gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI), nuclear medical imaging in predicting post-hepatectomy liver failure was gradually being explored. ConclusionsThe combination of clinical parameters and volumetric studies is used to assess preoperative liver function reserve for patients with HCC. The clinical applications of nuclear medical imaging and Gd-EOB-DTPA-enhanced MRI make up for the deficiency of local liver function reserve evaluation, which are important examinations to assess liver function reserve after conversion therapy in the future. However, more domestic studies are still needed to confirm their values.
