Impact of E-cadherin and its transcription regulators on assessing epithelial-mesenchymal transition in chronic hepatitis C virus infection.

Background: The mechanisms of chronic hepatitis C virus (HCV)-induced liver fibrosis and hepatocarcinogenesis are still poorly recognized. Therefore, this study aimed to determine the effect of chronic HCV infection on the expression of the major regulators of epithelial-mesenchymal transition (EMT) including E-cadherin, Snail, Slug, and Twist2, in the Egyptian population. This will help to design more efficient strategies to treat HCV-associated cirrhosis and carcinoma.

The interaction between microRNA-152 and DNA methyltransferase-1 as an epigenetic prognostic biomarker in HCV-induced liver cirrhosis and HCC patients.

The necessity for early detection and hence improving the outcome of treatment of hepatocellular carcinoma (HCC) is critical especially in Hepatitis C virus (HCV)-Genotype 4 induced cases. In our current work, we examined the miRNA-152 and DNMT-1 expression in chronic liver disease (CLD) due to HCV genotype 4 infection with/without cirrhosis and HCC patients as an attempt to evaluate the potential benefits of these new circulating, noninvasive, prognostic, epigenetic markers for liver cirrhosis and carcinogenesis of Egyptian patients. Eighty subjects were included in this study, divided into two groups; group I (40 patients) were classified into subgroup Ia (CLD without cirrhosis, n = 18) and subgroup Ib (CLD with cirrhosis, n = 22), group II (CLD patients with HCC, n = 20), and control (Healthy volunteer, n = 20).

miRNA-221 and miRNA-222 are promising biomarkers for progression of liver fibrosis in HCV Egyptian patients.

Background: Current methodologies used to determine the progression of hepatic fibrosis rely heavily on liver biopsy, a dangerous and invasive procedure, with semi-subjective analysis of the results of the biopsy. Thus, a new approach is immensely needed for monitoring the progression of liver fibrosis in Hepatitis C virus (HCV) patients.

Aim Of Work: The purpose of this study was to find highly specific and sensitive miRNA biomarkers that can be used to detect different stages of liver fibrosis.

Evaluation of Fecal M2PK as a Diagnostic Marker in Colorectal Cancer.

Background: Invasive colonoscopy is the gold standard for patients at risk for colorectal cancer. However, the need for non-invasive and specific markers is required.

Objective: To evaluate the sensitivity of the glycolytic pyruvate kinase isoenzyme type M2 dimer (M2PK) as a diagnostic biomarker for colorectal cancer (CRC) and adenomatous colorectal polyps (CRP) screening.

Performance of Disease-Specific Scoring Models in Intensive Care Patients with Severe Liver Diseases.

Introduction: Egypt has the highest prevalence of Hepatitis C Virus (HCV) in the world, estimated nationally at 14.7%. HCV treatment consumes 20% ($80 million) of Egypt's annual health budget.

Serum Markers of Epithelial Mesenchymal Transition as Predictors of HCV-induced Liver Fibrosis, Cirrhosis and Hepatocellular Carcinoma.

Introduction: Hepatitis C virus (HCV) is a major cause of chronic liver disease in Egypt, leading to hepatic fibrosis, liver cirrhosis (LC), and hepatocellular carcinoma (HCC). Liver fibrosis is characterized by excessive deposition of extracellular matrix (ECM). Newly-recognized pathogenic mechanisms point to the epithelial-mesenchymal transition (EMT) of hepatocytes to matrix synthesizing (myo-) fibroblasts.

Impact of hyponatremia on frequency of complications in patients with decompensated liver cirrhosis.

Introduction: Hyponatremia is common in cirrhosis. The relationship between hyponatremia and severity of cirrhosis is evidenced by its close association with the occurrence of complications, the prevalence of hepatic encephalopathy, hepatorenal syndrome, spontaneous bacterial peritonitis, refectory ascites, and hepatic hydrothorax. The aim of this study was assess the impact of hyponatremia on the occurrence of both liver-related complications and the hemodynamic cardiovascular dysfunction.

Predictors of In-Hospital Mortality in patients with hepatocellular carcinoma and Acute Variceal bleeding.

Introduction: Detection of hepatocellular carcinoma (HCC) in cirrhotic patients remains a serious, unsolved problem, and the risk factors for acute variceal bleeding (AVB) in HCC patients remain unclear. This study aimed to determine the in-hospital mortality (IHM) and factors influencing the clinical outcomes of AVB in patients with liver cirrhosis and HCC.

Methods: This was a retrospective, non-randomized, clinical study that was conducted in 2014.

NON-INVASIVE PREDICTORS FOR THE PRESENCE, GRADE AND RISK OF BLEEDING FROM ESOPHAGEAL VARICES IN PATIENTS WITH POST-HEPATITIC CIRRHOSIS.

Variceal bleeding is the last step of a chain of events initiatedby an increase in portal pressure, followed by the development and progressive dilation ofvarices until these finally rupture and bleed. The ideal method to diagnose portal hypertension should be accurate, noninvasive, objective, and reproducible. The study evaluated the predictive value of two non-invasive parameters for the diagnosis of esophageal varices (EV): 1-Right liver lobe diameter/serum albumin ratios (RLLD/S.
