| 1 | Multiplex RT-PCR-based detections of CEA, CK20 and EGFR in colorectal cancer patients显示文摘AIM: To develop a multiplex reverse transcription polymerase chain reaction (RT-PCR) method detecting cir-culating tumor cells in the peripheral blood of colorectal cancer (CRC) patients. METHODS: Peripheral blood samples were collected from 88 CRC patients and 40 healthy individuals from the blood donors' clinic and subsequently analyzed by multiplex RT-RCR for the expression of carcinoembryonic antigen (CEA), cytokeratin 20 (CK20) and epidermal growth factor receptor (EGFR) mRNA. The analysis involved determining the detection rates of CEA, CK20 and EGFR transcripts vs disease stage and overall survival. Median follow-up period was 19 mo (range 8-28 mo). RESULTS: Rates of CEA, CK20 and EGFR detection in CRC patients were 95.5%, 78.4% and 19.3%, respectively. CEA transcripts were detected in 3 healthy volunteer samples (7.5%), whereas all control samples were tested negative for CK20 and EGFR transcripts. The increasing number of positive detections for CEA, CK20 and EGFR transcripts in each blood sample was positively correlated with Astler-Coller disease stage (P< 0.001) and preoperative serum levels of CEA (P=0.029) in CRC patients. Data analysis using Kaplan-Meier estimator documented signif icant differences in the overall survival of the different CRC patient groups as formed according to the increasing number of positivity for CEA, CK20 and EGFR transcripts. CONCLUSION: These data suggest that multiplex RTPCR assay can provide useful information concerning disease stage and overall survival of CRC patients. | Aikaterini Tsouma Chrysanthi Aggeli Panagiotis Lembessis George N Zografos Dimitris P Korkolis Dimitrios Pectasides Maria Skondra Nikolaos Pissimissis Anastasia Tzonou Michael Koutsilieris | 2010 | World Journal of Gastroenterology2010，16，47： | 19 |
| 2 | Cartilage oligomeric matrix protein: A novel non-invasive marker for assessing cirrhosis and risk of hepatocellular carcinoma显示文摘AIM: To assess serum cartilage oligomeric matrix protein(COMP) as a marker of cirrhosis and risk of progression to hepatocellular carcinoma(HCC). METHODS: A COMP enzyme-linked immunosorbentassay was used to test 187 patients with chronic liver diseases at the time point of first evaluation. The selected patients included 72 with chronic hepatitis B infection, 75 with chronic hepatitis C infection, 22 with primary biliary cirrhosis, 7 with autoimmune hepatitis type 1, and 11 with alcoholic liver disease. Demographic, biochemical, histological and clinical characteristics of the patients were recorded at the first evaluation. One hundred and forty-seven patients were followed for a median [interquartile range(IQR)] duration of 96.5(102) mo. The clinical, biochemical and histological data, as well as the development of cirrhosis, HCC according to internationally accepted criteria and in case of death, a liver-related cause during the follow-up period, were recorded at the electronic database of our clinic. COMP determination was also performed in 43 healthy individuals who served as the control study group.RESULTS: COMP positivity(> 15 U/L) was detected in 22%-36% among chronic liver disease groups. Strikingly, almost 83% of COMP-positive patients were cirrhotic at baseline, independently of cause of liver disease. Among the patients who developed HCC during follow-up, 73.7%(14/19) were COMP positive at baseline. COMP positivity was significantly associated with older age(P < 0.001), advanced fibrosis(P = 0.001) and necroinflammatory activity(P = 0.001), higher aspartate aminotransferase(P < 0.001), alanine aminotransferase(P < 0.02), γ-glutamyl transpeptidase(P = 0.003), alkaline phosphatase(P = 0.001), bilirubin(P < 0.05), international normalized ratio(P = 0.002) and alpha-fetoprotein levels(P < 0.02), and lower albumin(P < 0.001), and platelet count(P = 0.008). COMP levels [median(IQR)] were significantly higher in cirrhotics compared to non-cirrhotics [13.8(7.9) U/L vs 9.8(4.6) U/L, respectively; P < 0.001]. On multivariate logistic regression analysis, COMP-positivity was independently associated only with cirrhosis(OR = 4.40, 95%CI: 1.33-14.69, P = 0.015). Kaplan-Meier analysis showed that COMP positivity was significantly associated with HCC development(P = 0.007) and higher incidence of liver-related death(P < 0.001). CONCLUSION: Elevated COMP levels are strongly associated with cirrhosis and HCC progression. Serum COMP is a new promising non-invasive biomarker for HCC risk assessment in surveillance programs. | Gary L Norman Nikolaos K Gatselis Zakera Shums Christos Liaskos Dimitrios P Bogdanos George K Koukoulis George N Dalekos | 2015 | World Journal of Hepatology2015，7，14： | 7 |
| 3 | Autophagy in liver diseases显示文摘Autophagy is the liver cell energy recycling system regulating a variety of homeostatic mechanisms.Damaged organelles,lipids and proteins are degraded in the lysosomes and their elements are re-used by the cell.Investigations on autophagy have led to the award of two Nobel Prizes and a health of important reports.In this review we describe the fundamental functions of autophagy in the liver including new data on the regulation of autophagy.Moreover we emphasize the fact that autophagy acts like a two edge sword in many occasions with the most prominent paradigm being its involvement in the initiation and progress of hepatocellular carcinoma.We also focused to the implication of autophagy and its specialized forms of lipophagy and mitophagy in the pathogenesis of various liver diseases.We analyzed autophagy not only in well studied diseases,like alcoholic and nonalcoholic fatty liver and liver fibrosis but also in viral hepatitis,biliary diseases,autoimmune hepatitis and rare diseases including inherited metabolic diseases and also acetaminophene hepatotoxicity.We also stressed the different consequences that activation or impairment of autophagy may have in hepatocytes as opposed to Kupffer cells,sinusoidal endothelial cells or hepatic stellate cells.Finally,we analyzed the limited clinical data compared to the extensive experimental evidence and the possible future therapeutic interventions based on autophagy manipulation. | Elias Kouroumalis Argryro Voumvouraki Aikaterini Augoustaki Dimitrios N Samonakis | 2021 | World Journal of Hepatology2021，13，1： | 7 |
| 4 | Systemic treatment for hepatocellular carcinoma:Still unmet expectations显示文摘Many patients with hepatocellular carcinoma(HCC) are diagnosed in an advanced stage, so they cannot be offered the option of curative treatments. The results of systemic chemotherapy are unsatisfactory and this has led to molecular targeted approaches.HCC develops in chronically damaged tissue due to cirrhosis in most patients. Several different cell types and molecules constitute a unique microenvironment in the liver, which has significant implications in tumor development and invasion. This, together with genome instability, contributes to a significant heterogeneity which is further enhanced by the molecular differences of the underlying causes. New classifications based on genetic characteristics of the tissue microenvironment have been proposed and key carcinogenic signaling pathways have been described. Tumor and adjacent tissue profiling seem biologically promising, but have not yet been translated into clinical settings. The encouraging first results with molecular- genetic signatures should be validated and clinically applicable. A more personalized approach to modern management of HCC is urgently needed. | Dimitrios N Samonakis Elias A Kouroumalis | 2017 | World Journal of Hepatology2017，9，2： | 6 |
| 5 | Clinical outcomes of compensated and decompensated cirrhosis: A long term study显示文摘AIM: To study these characteristics and prognostic patterns in a Greek patient population.METHODS: We analyzed a large cohort of cirrhotic patients referred to the department of Gastroenterology and Hepatology and the outpatient clinics of this tertiary hospital, between 1991 and 2008. We included patients with established cirrhosis, either compensated or decompensated, and further decompensation episodes were registered. A data base was maintained and updated prospectively throughout the study period.We analyzed differences in cirrhosis aetiology, time to and mode of decompensation, hepatocellular carcinoma(HCC) occurrence and ultimately patient survival.RESULTS: Five hundreds and twenty-two patients with median age 67(range, 29-91) years and average follow up 9 years-10 mo(range, 1-206 mo) were studied. Commonest aetiology was hepatitis C virus(HCV, 41%) followed by alcohol(31%). The median survival time in compensated cirrhotics was 115 mo(95%CI: 95-133), whereas in decompensated patients was 55 mo(95%CI: 36-75). HCV patients survived longer while HBV patients had over twice the risk of death of HCV patients. The median time to decompensation was 65 mo(95%CI: 51-79), with alcoholics having the highest risk(RR = 2.1 vs HCV patients). Hepatitis B virus(HBV) patients had the highest risk of HCC, alcoholics the lowest. Leading causes of death: liver failure, hepatorenal syndrome, sepsis and HCC progression. CONCLUSION: Cirrhosis aetiology and decompensation at presentation were predictors of survival. Alcoholics had the highest decompensation risk, HBV cirrhotics the highest risk of HCC and HCV cirrhotics the highest decompensation-free time. | Dimitrios N Samonakis Mairi Koulentaki Constantina Coucoutsi Aikaterini Augoustaki Chryssavgi Baritaki Emmanuel Digenakis Nikolaos Papiamonis Maria Fragaki Erminia Matrella Elias A Kouroumalis Maria Tzardi | 2014 | World Journal of Hepatology2014，6，7： | 4 |

| 7 | Novel approaches for the treatment of ventricular tachycardia显示文摘Ventricular tachycardia(VT) is a crucial cause of sudden cardiac death(SCD) and a primary cause of mortality and morbidity in patients with structural cardiac disease. VT includes clinical disorders varying from benign to lifethreatening. Most life-threatening episodes are correlated with coronary artery disease, but the risk of SCD varies in certain populations, with various underlying heart conditions, specific family history, and genetic variants. The targets of VT management are symptom alleviation, improved quality of life, reduced implantable cardioverter defibrillator shocks, prevention of reduction of left ventricular function, reduced risk of SCD, and improved overall survival. Antiarrhythmic drug therapy and endocardial catheter ablation remains the cornerstone of guideline-endorsed VT treatment strategies in patients with structural cardiac abnormalities. Novel strategies such as epicardial ablation, surgical cryoablation, transcoronary alcohol ablation, pre-procedural imaging, and stereotactic ablative radiotherapy are an appealing area of res-earch. In this review, we gathered all recent advances in innovative therapies as well as experimental evidence focusing on different aspects of VT treatment that could be significant for future favorable clinical applications. | Michael Spartalis Eleftherios Spartalis Eleni Tzatzaki Diamantis I Tsilimigras Demetrios Moris Christos Kontogiannis Efthimios Livanis Dimitrios C Iliopoulos Vassilis Voudris George N Theodorakis | 2018 | World Journal of Cardiology2018，10，7： | 2 |
