Apelin Association with Hepatic Fibrosis and Esophageal Varices in Patients with Chronic Hepatitis C Virus.

Portal hypertension and esophageal varices complicating hepatitis C virus (HCV)-related chronic liver diseases are some of the most devastating sequelae. Angiogenesis is the hallmark of their pathogenesis. Apelin is one of the recently identified angiogenic and fibrogenic peptides.

COVID-19 clinical and laboratory diagnosis overview.

Background: COVID-19 was identified in Wuhan, China, in December 2019, and rapidly spread worldwide, being declared global pandemic on the 11th of March 2020. Since its emergence, COVID-19 has raised global concerns associated with drastic measures that were never adopted in any previous outbreak, to contain the situation as early as possible.

Main Body: The 2019 novel corona virus (2019-nCoV) or SARS-CoV-2 is the causative agent of COVID-19.

Role of physical function in predicting short-term treatment outcome in Egyptian acute myeloid leukemia patients: a single center experience.

Background: Acute myeloid leukemia (AML) is a potentially fatal hematological disease. Along with disease-related factors, patient-related factors, in particular age, are a strong predictor of outcome that influence treatment decisions. Many acute myeloid leukemia risk stratification models have been developed to predict the outcome of intensive chemotherapy.

Towards hepatitis C virus elimination: Egyptian experience, achievements and limitations.

Worldwide, more than one million people die each year from hepatitis C virus (HCV) related diseases, and over 300 million people are chronically infected with hepatitis B or C. Egypt used to be on the top of the countries with heavy HCV burden. Some countries are making advances in elimination of HCV, yet multiple factors preventing progress; remain for the majority.

Extracellular Matrix Proteins Substantiate IL-28B T allele Effect on Histological Outcome of Chronic Hepatitis C.

Introduction And Aim: The correlation between interleukin-28B (IL-28B) polymorphisms and chronic hepatitis C (CHC) progression is debatable. Here, we aimed to evaluate the relation between IL-28B C/T genotypes and the development of cirrhotic liver. Extracellular matrix (ECM) proteins, FibroScan and model for end-stage liver disease (MELD) were used to substantiate the severity of liver disease.

Evaluating Diagnostic Accuracy of Noninvasive Tests in Assessment of Significant Liver Fibrosis in Chronic Hepatitis C Egyptian Patients.

Stage of liver fibrosis is critical for treatment decision and prediction of outcomes in chronic hepatitis C (CHC) patients. We evaluated the diagnostic accuracy of transient elastography (TE)-FibroScan and noninvasive serum markers tests in the assessment of liver fibrosis in CHC patients, in reference to liver biopsy. One-hundred treatment-naive CHC patients were subjected to liver biopsy, TE-FibroScan, and eight serum biomarkers tests; AST/ALT ratio (AAR), AST to platelet ratio index (APRI), age-platelet index (AP index), fibrosis quotient (FibroQ), fibrosis 4 index (FIB-4), cirrhosis discriminant score (CDS), King score, and Goteborg University Cirrhosis Index (GUCI).

β globin gene haplotype and the stroke risk among Egyptian children with sickle cell disease.

Background And Aim Of Work: Sickle cell disease (SCD) is an inherited disease of the beta globin gene. The β globin gene haplotypes are Senegal, Benin, Bantu, Cameroon, Arab-Indian and atypical haplotypes. In SCD, stroke is a life-threatening event in both adults and children.

Determinants of Infection Outcome in HCV-Genotype 4.

Hepatitis C virus (HCV) infection represents a worldwide health problem and has been for long an attractive point of research due to diversity among different genotypes regarding unique geographical distribution and diverse treatment outcome. HCV is considered a major cause of chronic liver disease and cirrhosis, which leads to liver failure and hepatocellular carcinoma requiring liver transplantation. Of the HCV genotypes identified, HCV genotype 4 (HCV-4) is the least studied.

Enhanced liver fibrosis test using ELISA assay accurately discriminates advanced stage of liver fibrosis as determined by transient elastography fibroscan in treatment naïve chronic HCV patients.

Evaluation of liver fibrosis stage is crucial in the assessment of chronic HCV patients, regarding decision to start treatment and during follow-up. Our aim was to assess the validity of the enhanced liver fibrosis (ELF) score in discrimination of advanced stage of liver fibrosis in naïve chronic HCV patients. We prospectively evaluated liver fibrosis stage in one hundred eighty-one naïve chronic HCV Egyptian patients by transient elastography (TE)-FibroScan.

Association of Toll-Like Receptor 3 and Toll-Like Receptor 9 Single Nucleotide Polymorphisms with Hepatitis C Virus Infection and Hepatic Fibrosis in Egyptian Patients.

Toll-like receptors (TLRs) are recognized as fundamental contributors to the immune system function against infections. Hepatitis C virus (HCV) infection represents a global health problem especially in Egypt having the highest HCV prevalence worldwide where HCV infection is a continuing epidemic. The aim of the present study was to investigate the possible association between genetic variation in TLR-3 and TLR-9 and HCV infection and hepatic fibrosis in chronic HCV-positive Egyptian patients.

MN1 and PTEN gene expression in acute myeloid leukemia.

Objective: Multiple genetic alterations with prognostic significance have been discovered in acute myeloid leukemia (AML). We studied the expression level of two genes, Meningioma1 (MN1) and Phosphatase and Tensin homolog (PTEN) to determine their expression in AML patients and their role as prognostic markers.

Methods: The study included 50 cytogenetic normal de novo AML cases and 10 controls, Their level was detected by Real time Reverse Transcription-Polymerase Chain Reaction.

Indoleamine 2,3-dioxygenase and regulatory T cells in acute myeloid leukemia.

Background And Objectives: The microenvironment of acute myeloid leukemia (AML) is suppressive for immune cells. Regulatory T cells (Tregs) have been recognized to play a role in helping leukemic cells to evade immunesurveillance. The mesenchymal stem cells (MSCs) are essential contributors in immunomodulation of the microenvironment as they can promote differentiation of Tregs via the indoleamine 2,3-dioxygenase (IDO) pathway.

The association of cytokine genes polymorphisms and susceptibility to aplastic anemia in Egyptian patients.

Background And Objective: Aplastic anemia (AA) remains a rare disease, with very interesting pathophysiology that is being investigated for years now. The present study aimed to determine the association between cytokine gene polymorphisms (TGF-β1 -509 C/T, TNF-α -308 G/A, IFN-γ +874 A/T) and susceptibility to AA in Egyptian patients.

Methods: The study included 80 participants subjected to determination of gene polymorphisms on genomic DNA using polymerase chain reaction-restriction fragment length polymorphism assay.

Association of interferon-γ inducible protein-10 pretreatment level and sustained virological response in HCV-positive Egyptian patients.

Background: The response to antiviral therapy in HCV infected patients depends on several predictive factors; however, the ability to achieve sustained virological response is still limited to around 60% of the patients infected with the HCV-4 genotype. Increased serum and intrahepatic interferon -γ inducible protein 10 (IP-10) levels in patients with chronic hepatitis C have been described. The aim of the work was to study the impact of pretreatment serum IP-10 level on the antiviral treatment outcome in a group of Egyptian patients infected with HCV.

B-cell activating factor promoter polymorphisms in egyptian patients with systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is a heterogonous autoimmune disease involving most immune cells. Studies have revealed a number of cytokine pathways that play important roles in the disease process. Among these is B- cell activating factor (BAFF), which regulates B-cell maturation, survival, and function.

Detection of HCV RNA in the peripheral blood mononuclear cells of serum HCV RNA-negative Egyptian patients under interferon treatment.

Introduction: Despite recent success after the introduction of combination therapy with interferon (IFN)-α and ribavirin, approximately 60% of patients with hepatitis C virus (HCV) genotype 4 fail to respond. Resistance to antiviral therapy remains a serious problem in the management of chronic hepatitis C. In most patients, HCV RNA could be detected in peripheral blood mononuclear cell (PBMC).
