1Cyclosporine versus tacrolimus in patients with HCV infection after liver transplantation:Effects on virus replication and recurrent hepatitis显示文摘瞄准:决定 calcineurin 禁止者, cyclosporine 和 tacrolimus 的效果,在丙肝上,在病人的周期性的丙肝的病毒(HCV ) 复制和活动张贴肝移植。方法:在我们的中心为在 1999 和 2003 之间的联系 HCV 的肝肝硬化收到了肝移植的 107 个病人的一个队的数据回顾地被分析。浆液 HCV-RNA 的水平和周期性的肝炎的活动在作为主要抑制免疫力的代理人和没在移植以后在开始的 12 瞬间以内导致胆汁的复杂并发症的不那样类似的抑制免疫力的政体收到了 cyclosporine 或 tacrolimus 的 47 个病人之间被比较。结果:HCV-RNA 在移植以后在 3 瞬间以内增加了,但是 cyclosporine 组和 tacrolimus 组之间的差别是不足道的(在 12 瞬间的 P=0.49 ) 。另外,由浆液 transaminases 决定了的周期性的肝炎并且门发炎和纤维变性的组织学的分级没在 12 瞬间(P=0.34 ) 以后显示出有效差量。结论:一个主要抑制免疫力的代理人不在肝移植以后在感染 HCV 的病人影响周期性的肝炎的正式就职或严厉的 Cyclosporine 或 tacrolimus。Philip Hilgard Alisan Kahraman Nils Lehmann Cornelia Seltmann Susanne Beckebaum R Stefan Ross Hideo A Baba Massimo Malago Christoph E Broelsch Guido Gerken 2006World Journal of Gastroenterology2006,12,5:235
2Diagnosis of biliary strictures after liver transplantation:Which is the best tool?显示文摘AIM: To evaluate the diagnostic value of different indirect methods like biochemical parameters, ultrasound (US) analysis, CT-scan and MRI/MRCP in comparison with endoscopic retrograde cholangiography (ERC), for diagnosis of biliary complications after liver transplantation. METHODS: In 75 patients after liver transplantation, who received ERC due to suspected biliary complications, the result of the cholangiography was compared to the results of indirect imaging methods performed prior to ERC. The cholangiography showed no biliary stenosis (NoST) in 25 patients, AST in 27 and ITBL in 23 patients. RESULTS: Biliary congestion as a result of AST was detected with a sensitivity of 68.4% in US analysis (specificity 91%), of 71% in MRI (specificity 25%) and of 40% in CT (specificity 57.1%). In ITBL, biliary congestion was detected with a sensitivity of 58.8% in the US, 88.9%in MRI and of 83.3% in CT. However, as anastomotic or ischemic stenoses were the underlying cause of biliary congestion, the sensitivity of detection was very low. InMRI detected the dominant stenosis at a correct localization in 22% and CT in 10%, while US failed completely. The biochemical parameters, showed no significant difference in bilirubin (median 5.7; 4,1; 2.5 mg/dL), alkaline phosphatase (median 360; 339; 527 U/L) or gamma glutamyl transferase (median 277; 220; 239 U/L) levels between NoST, AST and ITBL.CONCLUSION: Our data confirm that indirect imaging methods to date cannot replace direct cholangiography for diagnosis of post transplant biliary stenoses. However MRI may have the potential to complement or precede imaging by cholangiography. Optimized MRCP-processing might further improve the diagnostic impact of this method.Thomas Zoepf Evelyn J.

3Interferon-α response in chronic hepatitis B-transfected HepG2.2.15 cells is partially restored by lamivudine treatment显示文摘AIM: To characterize the IFN-response and its modul- ation by the antiviral compound lamivudine in HBV- transfected HepG2.2.15 cells. METHODS: HepG2.2.15 and HepG2 cells were stimulated with various concentrations of IFN-a2a in the presence or absence of lamivudine. Then, total RNA was extracted and analysed by customised cDNA arrays and northern blot for interferon-inducible genes (ISGs). In addition, cellular proteins were extracted for EMSA and western blot. HBV replication was assessed by southern blot or ELISAs for HBsAg and HBeAg. RESULTS: Two genes (MxA, Cig5) with completely abolished and 4 genes (IFITM1, -2, -3, and 6-16) with partially reduced IFN-responses were identified in HepG2.2.15 cells. In 2 genes (IFITM1, 6-16), the response to IFN-a could be restored by treatment with lamivudine. This effect could not be explained by a direct modulation of the Jak/Stat signalling pathway since EMSA and western blot experiments revealed no suppression of Stat1 activation and ISGF3 formation after stimulation with IFN-a in HepG2.2.15 compared to HepG2 cells. CONCLUSION: These results are consistent with the assumption that chronic hepatitis B may specifically modulate the cellular response to IFN by a selective blockage of some ISGs. Antiviral treatment with lamivudine may partially restore ISG expression by reducing HBV gene expression and replication.Shi-He Guan Mengji Lu Petra Grünewald Michael Roggendorf Guido Gerken Joerg F Schlaak 2007World Journal of Gastroenterology2007,13,2:22
4Potential triggering factors of acute liver failure as a first manifestation of autoimmune hepatitis-a single center experience of 52 adult patients显示文摘AIM To investigate potential triggering factors leading to acute liver failure(ALF) as the initial presentation of autoimmune hepatitis(AIH).METHODS A total of 565 patients treated at our Department between 2005 and 2017 for histologically-proven AIH were retrospectively analyzed. However, 52 patients(9.2%) fulfilled the criteria for ALF defined by the 'American Association for the Study of the Liver(AASLD)'. According to this definition, patients with 'acute-on-chronic' or 'acute-on-cirrhosis' liver failure were excluded. Following parameters with focus on potential triggering factors were evaluated: Patients' demographics, causation of liver failure, laboratory data(liver enzymes, MELD-score, autoimmune markers, virus serology), liver histology, immunosuppressive regime, and finally, outcome of our patients.RESULTS The majority of patients with ALF were female(84.6%) and mean age was 43.6 ± 14.9 years. Interestingly, none of the patients with ALF was positive for antiliver kidney microsomal antibody(LKM). We could identify potential triggering factors in 26/52(50.0%) of previously healthy patients presenting ALF as their first manifestation of AIH. These were drug-induced ALF(57.7%), virus-induced ALF(30.8%), and preceding surgery in general anesthesia(11.5%), respectively. Unfortunately, 6 out of 52 patients(11.5%) did not survive ALF and 3 patients(5.7%) underwent liver transplantation(LT). Comparing data of survivors and patients with non-recovery following treatment, MELDscore(P < 0.001), age(P < 0.05), creatinine(P < 0.01), and finally, ALT-values(P < 0.05) reached statistical significance. CONCLUSION Drugs, viral infections, and previous surgery may trigger ALF as the initial presentation of AIH. Advanced age and high MELD-score were associated with lethal outcome.Matthias Buechter Paul Manka Falko Markus Heinemann Monika Lindemann Hideo Andreas Baba Martin Schlattjan Ali Canbay Guido Gerken Alisan Kahraman 2018World Journal of Gastroenterology2018,24,13:8

6Successful photodynamic therapy for biliary papillomatosis:A case report显示文摘Papillomatosis of the bile duct is a rare disease with a high risk of malignant transformation. Therapeutical options include partial hepatectomy and liver transplantation. A previously healthy 65-years old male developed jaundice and right upper abdominal quadrant pain in 1996. A villous adenoma of the distal bile duct was diagnosed. A Whipple procedure was performed. In 2002 the patient turned symptomatic again. Another adenoma was found in the right hepatic duct resulting in a right hepatectomy. Two years later the patient again developed cholestasis. After drainage of the left hepatic duct with a percutaneous transhepatic cholangial drainage (PTCD) catheter, a recurrent biliary adenomatosis was diagnosed by cholangioscopy. As there was no surgical option left, the patient received photodynamic therapy (PDT) for the recurrent biliary papillomatosis. Three mo after he received further photodynamic therapies, the bile duct epithelium appeared normal and the patient had no signs of adenomatosis, both macroscopically and histologically. The follow-up cholangioscopy in late 2005 revealed only a small papilloma without the need for intervention. In early 2006, the patient died of multi organ failure without signs of extrahepatic cholestasis or cholangitis at the age of 75, 10 years after the diagnosis of biliary papillomatosis was established. The patient exceeded the average life expectancy of patients with biliary papillomatosis by far. Thus, PDT might be a sufficient therapeutic option for recurrent papillomatosis patients with no significant side effects.Lars P Bechmann Philip Hilgard Andrea Frilling Brigitte Schumacher Hideo A Baba Guido Gerken Thomas Zoepf 2008World Journal of Gastroenterology2008,14,26:7

8Bcl-2 degradation is an additional pro-apoptotic effect of polo-like kinase inhibition in cholangiocarcinoma cells显示文摘AIM To examine the influence on apoptotic mechanisms following inhibition of polo-like kinases as therapeuticallyapproach for cholangiocellular cancer treatment. METHODS As most cholangiocarcinomas are chemotherapyresistant due to mechanisms preventing tumor cell death, we investigated the effect of Cisplatin on cholangiocellular carcinoma(CCA) cell lines KMCH-1 and Mz-Ch-1. Polo-like kinases(PLK) are important regulators of the cell cycle and their inhibition is discussed as a potential therapy while PLK inhibition can regulate apoptotic mediators. Here, cells were treated with PLK inhibitor BI6727(Volasertib), Cisplatin, and in combination of both compounds. Cell viability was assessed by MTT; apoptosis was measured by DAPI staining and caspase-3/-7 assay. Western blot and q RT-PCR were used to measure expression levels of apoptosis-related molecules Bax and Bcl-2. RESULTS The cell viability in the CCA cell lines KMCH-1 and Mz-Ch-1 was reduced in all treatment conditions compared to vehicle-treated cells. Co-treatment with BI6727 and cisplatin could even enhance the cytotoxic effect of cisplatin single treatment. Thus, co-treatment of cisplatin with BI6727 could slightly enhance the cytotoxic effect of the cisplatin in both cell lines whereas there was evidence of increased apoptosis induction solely in Mz-Ch-1 as compared to KMCH-1. Moreover, PLK inhibition decreases protein levels of Bcl-2; an effect that can be reversed by the proteasomal degradation inhibitor MG-132. In contrast, protein levels of Bax were not found to be altered by PLK inhibition. These findings indicate that cytotoxic effects of Cisplatin in Mz-Ch-1 cells can be enhanced by co-treatment with BI6727.CONCLUSION In conclusion, BI6727 treatment can sensitize CCA cells to cisplatin-induced apoptosis with proteasomal Bcl-2 degradation as an additional pro-apoptotic effect.Svenja Sydor Sami Jafoui Lena Wingerter Sandra Swoboda Joachim C Mertens Guido Gerken Ali Canbay Andreas Paul Christian D Fingas 2017World Journal of Gastroenterology2017,23,22:5
9FibroSURE^(TM) and FibroScan~ in relation to treatment response in chronic hepatitis C virus显示文摘AIM:To compare histological endpoint assessment using noninvasive alternatives to biopsy during treatment in a chronic hepatitis C virus(HCV)cohort.METHODS:Patients with chronic HCV were randomized to receive interferon-based therapy for 24(genotypes 2/3)or 48(genotype 1)wk.FibroSURE~TM(FS)was assessed at baseline and at week-12 post-treatment follow-up.Baseline biopsy for METAVIR was assessed by a single pathologist.FibroScan~ transient elastogra-phy(TE)was performed during treatment in a patient subset.RESULTS:Two thousand and sixty patients(n = 253 in Asia)were classif ied as METAVIR F0-1(n = 1682)or F2-4(n = 378).For F2-4,FS(n = 2055)had sensitiv-ity and specif icity of 0.87 and 0.61,respectively,with area under the receiver-operating curve of 0.82;corre-sponding values for TE(n = 214)and combined FS/TE(n = 209)were 0.77,0.88 and 0.88,and 0.93,0.68 and 0.88.Overall FS/TE agreement for F2-4 was 71%(κ = 0.41)and higher in Asians vs non-Asians(κ = 0.86 vs 0.35;P < 0.001).Combined FS/TE had 97% accuracy in Asians(n = 33).Baseline FS(0.38 vs 0.51,P < 0.001)and TE(8.0 kPa vs 11.9 kPa,P = 0.006)scores were lower in patients with sustained virological response than in nonresponders,and were maintained through follow-up.CONCLUSION:FS and TE may reliably differentiate mild from moderate-advanced disease,with a potential for high diagnostic accuracy in Asians with chronic HCV.Keyur Patel Mireen Friedrich-Rust Yoav Lurie Mircea Grigorescu Carol Stanciu Chuan-Mo Lee Eugene R Schiff Dieter Hussinger Michael P Manns Guido Gerken Isabelle Colle Michael Torbenson Erik Pulkstenis G Mani Subramanian John G McHutchison Stefan Zeuzem 2011World Journal of Gastroenterology2011,17,41:4
