| 1 | Autoimmune liver serology:Current diagnostic and clinical challenges显示文摘Liver-related autoantibodies are crucial for the correct diagnosis and classification of autoimmune liver diseas-es(AiLD),namely autoimmune hepatitis types 1 and 2(AIH-1 and 2),primary biliary cirrhosis(PBC),and the sclerosing cholangitis variants in adults and children.AIH-1 is specified by anti-nuclear antibody(ANA) and smooth muscle antibody(SMA).AIH-2 is specified by antibody to liver kidney microsomal antigen type-1(anti-LKM1) and anti-liver cytosol type 1(anti-LC1).SMA,ANA and anti-LKM antibodies can be present in de-novo AIH following liver transplantation.PBC is specified by antimitochondrial antibodies(AMA) react-ing with enzymes of the 2-oxo-acid dehydrogenase complexes(chiefly pyruvate dehydrogenase complex E2 subunit) and disease-specific ANA mainly react-ing with nuclear pore gp210 and nuclear body sp100.Sclerosing cholangitis presents as at least two variants,first the classical primary sclerosing cholangitis(PSC) mostly affecting adult men wherein the only(and non-specific) reactivity is an atypical perinuclear antineutro-phil cytoplasmic antibody(p-ANCA),also termed peri-nuclear anti-neutrophil nuclear antibodies(p-ANNA) and second the childhood disease called autoimmune sclerosing cholangitis(ASC) with serological features resembling those of type 1 AIH.Liver diagnostic serol-ogy is a fast-expanding area of investigation as new purified and recombinant autoantigens,and automatedtechnologies such as ELISAs and bead assays,become available to complement(or even compete with) tradi-tional immunofluorescence procedures.We survey for the first time global trends in quality assurance impact-ing as it does on(1) manufacturers/purveyors of kits and reagents,(2) diagnostic service laboratories that fulfill clinicians' requirements,and(3) the end-user,the physician providing patient care,who must properly interpret test results in the overall clinical context. | Dimitrios P Bogdanos Diego Vergani Pietro Invernizzi Ian R Mackay | 2008 | World Journal of Gastroenterology2008,14,21: | 40 |
| 2 | History of the infantile hepatic hemangioma:From imaging to generating a differential diagnosis显示文摘We aim to provide an up-to-date summary of infantile hepatic hemangioma(IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver.Eligible peer-reviewed articles on hepatic infantile hemangiomas,published between 2000 and 2015,were reviewed for this study.IHH is the most common hepatic vascular tumor in children.Once a liver mass is identified in an infant,the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma,hepatoblastoma,metastatic neuroblastoma,so careful physical examination,imaging studies,and,if indicated,tumor markers and biopsy,are of pivotal importance to ascertain the correct diagnosis.Despite the benign nature of IHHs,some of these lesions may demand medical and/or surgical intervention,especially for multiple and diffuse IHH.Complications can include hepatomegaly,hypothyroidism and cardiac failure.Therefore,a close follow-up is required until complete involution of the lesions.We propose an algorithm to guide the physicians towards the proper management of hepatic lesions. | Maria Gnarra Gerald Behr Alison Kitajewski June K Wu Sudha A Anupindi Carrie J Shawber Nick Zavras Dimitrios Schizas Chris Salakos Konstantinos P Economopoulos | 2016 | World Journal of Clinical Pediatrics2016,5,3: | 27 |
| 3 | 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 |
| 4 | Helicobacter pylori and autoimmune disease:Cause or bystander显示文摘Helicobacter pylori(H.pylori)is the main cause of chronic gastritis and a major risk factor for gastric cancer.This pathogen has also been considered a potential trigger of gastric autoimmunity,and in particular of autoimmune gastritis.However,a considerable number of reports have attempted to link H.pylori infection with the development of extra-gastrointestinal autoimmune disorders,affecting organs not immediately relevant to the stomach.This review discusses the current evidence in support or against the role of H.pylori as a potential trigger of autoimmune rheumatic and skin diseases,as well as organ specific autoimmune diseases.We discuss epidemiological,serological,immunological and experimental evidence associating this pathogen with autoimmune diseases.Although over one hundred autoimmune diseases have been investigated in relation to H.pylori,we discuss a select number of papers with a larger literature base,and include Sj grens syndrome,rheumatoid arthritis,systemic lupus erythematosus,vasculitides,autoimmune skin conditions,idiopathic thrombocytopenic purpura,autoimmune thyroid disease,multiple sclerosis,neuromyelitis optica and autoimmune liver diseases.Specific mention is given to those studies reporting an association of anti-H.pylori antibodies with the presence of autoimmune disease-specific clinical parameters,as well as those failing to find such associations.We also provide helpful hints for future research. | Daniel S Smyk Andreas L Koutsoumpas Maria G Myt-ilinaiou Eirini I Rigopoulou Lazaros I Sakkas Dimitrios P Bogdanos | 2014 | World Journal of Gastroenterology2014,20,3: | 12 |

| 6 | Cytopathologic diagnosis of fine needle aspiration biopsies of thyroid nodules显示文摘Fine-needle aspiration(FNA) cytology is an important diagnostic tool in patients with thyroid lesions.Several systems have been proposed for the cyropathologic diagnosis of the thyroid nodules.However cases with indeterminate cytological findings still remain a matter of debate.In this review we analyze all literature regarding Thyroid Cytopathology Reporting systems trying to identify the most suitable methodology to use in clinical practice for the preoperative diagnosis of thyroid nodules.A review of the English literature was conducted,and data were analyzed and summarized and integrated from the authors' perspective.The main purpose of thyroid FNA is to identify patients with higher risk for malignancy,and to prevent unnecessary surgeries for benign conditions.The Bethesda System for Reporting Thyroid Cytopathology is the most widely used system for the diagnosis of thyroid FNA specimens.This system also contains guidelines for the diagnosis and treatment of indeterminate or suspicious for malignancy cases.In conclusion,patients who require repeated FNAs for indeterminate diagnoses will be resolved by repeat FNA in a percentage of 72%-80%. | Evangelos P Misiakos Niki Margari Christos Meristoudis Nickolas Machairas Dimitrios Schizas Konstantinos Petropoulos Aris Spathis Petros Karakitsos Anastasios Machairas | 2016 | World Journal of Clinical Cases2016,4,2: | 12 |
| 7 | Pancreatic duct guidewire placement for biliary cannulation in a single-session therapeutic ERCP显示文摘AIM: To investigate the technical success and clinical complication rate of a cannulated pancreatic duct with guidewire for biliary access. METHODS: During a five-year study period, a total of 2843 patients were included in this retrospective analysis. Initial biliary cannulation method consisted of single-guidewire technique (SGT) for up to 5 attempts, followed by double-guidewire technique (DGT) when repeated unintentional pancreatic duct cannulation had taken place. Pre-cut papillotomy technique was reserved for when DGT had failed or no pancreatic duct cannulation had been previously achieved. Main outcome measurements were defined as biliary cannu-lation success and post-endoscopic retrograde cholangiopancreatography (ERCP) complication rate. RESULTS: SGT (92.3% success rate) was characterized by statistically significant enhanced patient outcome compared to either the DGT (43.8%, P < 0.001), pre-cut failed DGT (73%, P < 0.001) or pre-cut as first step method (80.6%, P = 0.002). Pre-cut as first step method offered a statistically significantly more favorable outcome compared to the DGT (P < 0.001). The incidence of post-ERCP pancreatitis did not differ in a statistically significant manner between either method (SGT: 5.3%, DGT: 6.1%, Pre-cut failed DGT: 7.9%, Pre-cut as first step: 7.5%) or with patients' gender. CONCLUSION: Although DGT success rate proved not to be superior to SGT or pre-cut papillotomy, it is considered highly satisfactory in terms of safety in order to avoid the risk of a pre-cut when biliary therapy is necessary in difficult-to-cannulate cases. | Dimitrios Xinopoulos Stefanos P Bassioukas Dimitrios Kypreos Dimitrios Korkolis Andreas Scorilas Konstantinos Mavridis Dimitrios Dimitroulopoulos Emmanouil Paraskevas | 2011 | World Journal of Gastroenterology2011,17,15: | 8 |
| 8 | 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 |

| 11 | Adrenal ganglioneuroma:What you need to know显示文摘Adrenal ganglioneuromas(GNs) constitute rare,differentiated tumors which originate from neural crest cells. GNs are usually hormonally silent and tend to be discovered incidentally on imaging tests. Adrenalectomy is the gold standard for the treatment of primary adrenal GNs. Nevertheless,preoperative differential diagnosis of GNs remains extremely challenging,and thus histopathological examination is required in order to confirm the diagnosis of GN. Overall,prognosis after surgical resection seems to be excellent,without any recurrences or need for adjuvant therapy. | Konstantinos S Mylonas Dimitrios Schizas Konstantinos P Economopoulos | 2017 | World Journal of Clinical Cases2017,5,10: | 5 |
| 12 | Simple hematological predictors of AF recurrence in patients undergoing atrial fibrillation ablation显示文摘Backgound Red cell distribution width(RDW) and neutrophil-to-lymphocyte ratio(NLR) are simple hematologic indices that have been used to predict adverse outcomes in different clinical settings. The aim of our study is to determine whether RDW and NLR can predict atrial fibrillation(AF) recurrence in patients undergoing AF ablation. Methods Consecutive patients, without known hematological disorders, who underwent AF catheter ablation between January 2014 and April 2017 were enrolled into this study. Blood samples were taken one day before and five hours after the ablation procedure. Results A total of 346 patients(224 males(65%), mean age: 59 ± 11 years old) were included. After a mean follow up of 26.2 ± 12.1 months, 80(23.1%) patients experienced late AF recurrence(defined as any recurrence after the blanking period of three months), while 97(28%) patients experienced early AF recurrence during the blanking period. Univariate analysis showed that early arrhythmia recurrence, type of AF and NLR after the procedure were significantly associated with late AF recurrence, while early arrhythmia recurrence and NLR remained significant in multivariate analysis. RDW was not associated with late AF recurrence. None of the parameters above predicted early arrhythmia recurrence. Conclusions Simple and inexpensive hematological indices such as NLR should be evaluated for their ability to predict AF recurrence in patients undergoing catheter ablation in larger prospective studies. | George Bazoukis Konstantinos P Letsas Konstantinos Vlachos Athanasios Saplaouras Dimitrios Asvestas Konstantinos Tyrovolas Aikaterini Rokiza Eirini Pagkalidou Gary Tse Stavros Stavrakis Antonios Sideris Michael Efremidis | 2019 | Journal of Geriatric Cardiology2019,16,9: | 4 |
| 13 | Presentation and surgical management of xanthogranulomatous cholecystitis显示文摘Background:Xanthogranulomatous cholecystitis(XGC)is a rare benign chronic inflammatory disease of the gallbladder that often presents as cholecystitis and most of the times requires surgical management.In addition,distinguishing XGC from gallbladder cancer preoperatively is still a challenge.The aim of the present systematic review was to outline the clinical presentation and surgical approach of XGC.Data sources:The present systematic review was designed using the PRISMA and AMSTAR guidelines.We searched MEDLINE,Scopus,Clinicaltrials.gov,EMBASE,Cochrane Central Register of Controlled Trials(CENTRAL)and Google Scholar databases from inception until June 2020.Results:The laparoscopic cholecystectomy rate(34%)was almost equal to the open cholecystectomy rate(47%)for XGC.An important conversion rate(35%)was observed as well.The XGC cases treated by surgery were associated with low mortality(0.3%),limited intraoperative blood loss(58-270 m L),low complication rates(2%–6%),along with extended operative time(82.6–120 minutes for laparoscopic and 59.6–240 minutes for open cholecystectomy)and hospital stay(3–9 days after laparoscopic and 8.3–18 days after open cholecystectomy).Intraoperative findings during cholecystectomies for XGC included empyema or Mirizzi syndrome.In addition,complex surgical procedures,like wedge hepatic resections and bile duct excision were required during operations for XGC.Conclusions:XGC seemed to be a rare,benign inflammatory disease that presents similar features as gallbladder cancer.The mortality and complication rates of XGC were low,despite the complex surgical procedures that might be required in some cases. | Maximos Frountzas Dimitrios Schizas Efstathia Liatsou Konstantinos P Economopoulos Christina Nikolaou Konstantinos G Apostolou Konstantinos G Toutouzas Evangelos Felekouras | 2021 | Hepatobiliary & Pancreatic Diseases International2021,20,2: | 4 |

| 15 | Reasons of PEG failure to eliminate gastroesophageal reflux in mechanically ventilated patients显示文摘AIM:To investigate factors predicting failure of percutaneous endoscopic gastrostomy(PEG)to eliminate gastroesophageal reflux(GER). METHODS:Twenty-nine consecutive mechanically ventilated patients were investigated.Patients were evaluated for GER by pH-metry pre-PEG and on the 7th post-PEG day.Endoscopic and histologic evidence of reflux esophagitis was also carried out.A beneficial response to PEG was considered when pH-metry on the 7th post-PEG day showed that GER was below 4%. RESULTS:Seventeen patients responded(RESP group)and 12 did not respond(N-RESP)to PEG.The mean age,sex,weight and APACHEⅡscore were similar in both groups.GER(%)values were similar in both groups at baseline,but were significantly reduced in the RESP group compared with the N-RESP group on the 7th post-PEG day[2.5(0.6-3.8)vs 8.1(7.4-9.2, P<0.001)].Reflux esophagitis and the gastroesophageal flap valve(GEFV)grading differed significantly between the two groups(P=0.031 and P=0.020, respectively).Histology revealed no significant differences between the two groups.CONCLUSION:Endoscopic grading of GEFV and the presence of severe reflux esophagitis are predisposing factors for failure of PEG to reduce GER in mechanically ventilated patients. | Emmanuel E Douzinas Ilias Andrianakis Olga Livaditi Dimitrios Bakos Katerina Flevari Nikos Goutas Dimitrios Vlachodimitropoulos Marios-Konstantinos Tasoulis Alex P Betrosian | 2009 | World Journal of Gastroenterology2009,15,43: | 2 |
| 16 | Serum zonulin levels in patients with liver cirrhosis:Prognostic implications显示文摘BACKGROUND Increased gut permeability and bacterial translocation play an important role in liver cirrhosis.Zonulin is a recently recognized protein involved in the disintegration of the intestinal barrier.AIM To investigate possible differences in serum zonulin levels among patients with different cirrhosis stages and their potential prognostic implications.METHODS Consecutive cirrhotic patients who attended our liver clinic were included in the study.Serum zonulin levels,clinical,radiological and biochemical data were collected at baseline.Patients who accepted participation in a regular surveillance program were followed-up for at least 12 mo.RESULTS We enrolled 116 cirrhotics[mean Child-Turcotte-Pugh(CTP)score:6.2±1.6;model for end-stage liver disease score:11±3.9].The causes of cirrhosis were viral hepatitis(39%),alcohol(30%),non-alcoholic fatty liver disease(17%),and other(14%).At baseline,53% had decompensated cirrhosis,48% had ascites,and 32% had history of hepatic encephalopathy.Mean zonulin levels were significantly higher in patients with CTP-B class than CTP-A class(4.2±2.4 ng/dL vs 3.5±0.9 ng/dL,P=0.038),with than without ascites(P=0.006),and with than without history of encephalopathy(P=0.011).Baseline serum zonulin levels were independently associated with the probability of decompensation at 1 year(P=0.039),with an area under the receiving operating characteristic of 0.723 for predicting hepatic decompensation.Higher CTP score(P=0.021)and portal vein diameter(P=0.022)were independent predictors of mortality.CONCLUSION Serum zonulin levels are higher in patients with more advanced chronic liver disease and have significant prognostic value in identifying patients who will develop decompensation. | Theodoros A Voulgaris Dimitrios Karagiannakis E Hadziyannis Spilios Manolakopoulos Georgios P Karamanolis George Papatheodoridis John Vlachogiannakos | 2021 | World Journal of Hepatology2021,13,10: | 2 |
| 17 | Barrett's esophagus with high-grade dysplasia:Focus on current treatment options显示文摘High-grade dysplasia(HGD) in Barrett's esophagus(BE) is the critical step before invasive esophageal adenocarcinoma.Although its natural history remains unclear,an aggressive therapeutic approach is usually indicated.Esophagectomy represents the only treatment able to reliably eradicate the neoplastic epithelium.In healthy patients with reasonable life expectancy,vagal-sparing esophagectomy,with associated low mortality and low early and late postoperative morbidity,is considered the treatment of choice for BE with HGD.Patients unfit for surgery should be managed in a less aggressive manner,using endoscopic ablation or endoscopic mucosal resection of the entire BE segment,followed by lifelong surveillance.Patients eligible for surgery who present with a long BE segment,multifocal dysplastic lesions,severe reflux symptoms,a large fixed hiatal hernia or dysphagia comprise a challenging group with regard to the appropriate treatment,either surgical or endoscopic. | Leonidas Lekakos Nikolaos P Karidis Dimitrios Dimitroulis Christos Tsigris Gregory Kouraklis Nikolaos Nikiteas | 2011 | World Journal of Gastroenterology2011,17,37: | 2 |
| 18 | Mechanisms of drug-induced proarrhythmia in clinical practice显示文摘Drug-induced proarrhythmia represents a great challenge for those involved in the development of novel pharmaceuticals and in the regulatory bodies for drug approval as well as for the prescribing clinicians.Our understanding of the mechanisms that underlie druginduced proarrhythmia has grown dramatically over the last two decades.A growing number of cardiac and non-cardiac agents have been shown to alter cardiac repolarization predisposing to fatal cardiac arrhythmias such as ventricular tachycardia or ventricular fibrillation and sudden cardiac death.These agents may induce the phenotype of long QT syndrome and less commonly of short QT syndrome and Brugada syndrome(BS).Although,genetic susceptibility underlie drug-induced proarrhythmia in certain cases,current data are limited regarding this topic.The present review surveys the current published literature on the mechanisms and the offending medical agents that predispose to drug-induced long QT syndrome,short QT syndrome and BS.Drug-induced proarrhythmia should be considered as a predictor of sudden cardiac death and should prompt critical re-evaluation of the risks and benefits of the suspicious medication.Survivors of drug-induced proarrhythmia and family members require careful examination and possibly genetic testing for the presence of a channelopathy.Treating physicians are advised to follow the lists of agents implicated in drug-induced proarrhythmia in order to minimize the risk of arrhythmia and sudden cardiac death. | Arkadia Konstantopoulou Spyros Tsikrikas Dimitrios Asvestas Panagiotis Korantzopoulos Konstantinos P Letsas | 2013 | World Journal of Cardiology2013,5,6: | 2 |
