Prognostic indicators of successful endoscopic sclerotherapy for prevention of rebleeding from oesophageal varices in cirrhosis: a long-term cohort s…
2000
Abstract Background. Although band ligation is now recommended for prevention of rebleeding from oesophageal varices in cirrhosis, sclerotherapy is still widely used. Patients submitted to chronic sclerotherapy undergo several endoscopies and experience a large number of serious complications. However, long-term outcome is poorly defined. Aims. To assess the clinical course and prognostic indicators of patients undergoing chronic sclerotherapy for prevention of variceal rebleeding as a basis for future evaluation of long-term band ligation outcome. Methods. Prospective cohort study prognostic analysis by the Cox proportional hazards model. Results. A total of 218 consecutive cirrhotic patie…
Color Doppler Ultrasound in Portal Hypertension
2020
Portal hypertension is one of the most important causes of morbidity and mortality in cirrhotic patients. A color Doppler evaluation of the left gastric vein (LGV) has proven utility in the prediction of esophageal varices and variceal bleeding in patients with portal hypertension. The purpose of this review is to discuss the ultrasound evaluation, imaging findings, and clinical application of Doppler ultrasound in the assessment of the LGV. Knowledge of the color Doppler technique and imaging findings of the LGV may help clinicians improve the monitoring of portal hypertension and predict patients with a high risk of esophageal varices.
Monitoring Occurrence of Liver-Related Events and Survival by Transient Elastography in Patients With Nonalcoholic Fatty Liver Disease and Compensate…
2021
[Background & Aims] Patients with advanced fibrosis related to nonalcoholic fatty liver disease (NAFLD) are at risk of developing hepatic and extrahepatic complications. We investigated whether, in a large cohort of patients with NAFLD and compensated advanced chronic liver disease, baseline liver stiffness measurements (LSMs) and their changes can be used to identify patients at risk for liver-related and extrahepatic events.
Prevention of upper gastrointestinal bleeding from portal hypertension in cirrhosis: rationale for medical treatment.
1992
We updated meta-analysis and critical descriptive analysis of randomized clinical trials (RCTs) assessing the value of beta-blockers in preventing first bleeding (prophylactic) or rebleeding (therapeutic) and on survival of patients with cirrhosis. Both the methods of Peto-Mantel-Haenszel and DerSimonian-Laird were used to assess the heterogeneity and obtain cumulative estimates of treatment effects; the L'Abbé plot was also used for a visual assessment of heterogeneity in the direction of treatment effect. Seven prophylactic and nine therapeutic RCTs were analysed. beta-Blockers uniformly reduced the bleeding risk and revealed a trend toward improved survival in non-ascitic, well-compensat…
Prescription rates of common medications in patients with decompensated cirrhosis in Germany
2021
Adequate pharmacological treatment is of pivotal importance to improve prognosis in patients with decompensated liver cirrhosis. We studied the adherence to recommended pharmacological treatments as secondary prevention in cirrhotic patients following a first decompensation in German primary care.Using the Disease Analyzer Database, the current study sample included patients with liver cirrhosis who had an initial diagnosis of a first decompensation event between 2015 and 2018 (index date) and a follow-up time of at least 6 months after the index date. Pharmacological treatments following the 6 months after the index date were studied.The study included 1538 patients with a first decompensa…
Management of hepatic encephalopathy in Germany: a survey among physicians
2020
Hepatic encephalopathy (HE) is a severe complication of liver cirrhosis with impairment of quality of life and prognosis. Management patterns among physicians have not been investigated yet. A questionnaire containing 17 questions was sent out to 1468 gastroenterologists and 120 general practitioners (GPs). It included questions regarding diagnostic, therapeutic, and management strategies used in patients with overt HE (OHE) and covert HE (CHE). The response rate was 12 % (n = 172) for gastroenterologists and 45 % (n = 54) for GPs. Of gastroenterologists, 26.7 % examine patients with an initial diagnosis of liver cirrhosis regarding HE. Gastroenterologists favored a combination of differen…
Emergency sclerotherapy versus vasoactive drugs for bleeding oesophageal varices in cirrhotic patients.
2010
Background Emergency sclerotherapy is still widely used as a first line therapy for variceal bleeding in patients with cirrhosis, particularly when banding ligation is not available or feasible. However, pharmacological treatment may stop bleeding in the majority of these patients. Objectives To assess the benefits and harms of emergency sclerotherapy versus vasoactive drugs for variceal bleeding in cirrhosis. Search methods Search of trials was based on The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded through January 2010. Selection criteri…
Into the wild of long non-coding RNA in gastrointestinal stromal tumors (GISTs) to explore new prognostic/predictive biomarkers
2015
Background: Long Non-coding RNAs (lncRNA) are emerging as essential regulators of genetic and epigenetic networks, and their deregulation may underlie complex diseases, such as carcinogenesis. Several studies have described lncRNAs alterations in patients with solid tumors. In particular, in Gastrointestinal Stromal Tumors (GIST), upregulation of HOTAIR has been associated with aggressiveness, metastasis, and poor patients’ survival. In order to gain more detailed insight on the molecular role of lncRNAs in GIST, we analyzed in vivo the expression levels of lncRNAs H19 and MALAT1 in surgically resected patients. Material and Methods: The expression of the lnc-RNAs H19 and MALAT1 was evaluat…
ST segment elevations: Always a marker of acute myocardial infarction?
2013
AbstractChest pain is one of the chief presenting complaints among patients attending Emergency department. The diagnosis of acute myocardial infarction may be a challenge. Various tools such as anamnesis, blood sample (with evaluation of markers of myocardial necrosis), ultrasound techniques and coronary computed tomography could be useful. However, the interpretation of electrocardiograms of these patients may be a real concern. The earliest manifestations of myocardial ischemia typically interest T waves and ST segment. Despite the high sensitivity, ST segment deviation has however poor specificity since it may be observed in many other cardiac and non-cardiac conditions. Therefore, when…
Virulent synergistic effect between Enterococcus faecalis and Escherichia coli assayed by using the Caenorhabditis elegans model.
2008
5 pages; International audience; BACKGROUND: The role of enterococci in the pathogenesis of polymicrobial infections is still debated. The purpose of this study was to evaluate the effect of virulent enterococci in the presence or absence of Escherichia coli strains in the in vivo Caenorhabditis elegans model. PRINCIPAL FINDINGS: This study demonstrated that there was a synergistic effect on virulence when an association of enterococci and E. coli (LT50 = 1.6 days+/-0.1 according to the tested strains and death of nematodes in 4 days+/-0.5) was tested in comparison with enterococci alone (LT50 = 4.6 days+/-0.1 and death in 10.4 days+/-0.6) or E. coli alone (LT50 = 2.1+/-0.9 and deaths 6.6+/…
