The hidden epidemic of occult hepatitis B and C among injection drug users (IDUs): A call for action.

Objective: This study aims to determine the prevalence of Occult Hepatitis B and C Infections among Egyptian injection drug users (IDUs) and identify key risk factors contributing to their occurrence within this high-risk group.

Methods: In this cross-sectional study, 200 Egyptian IDUs were assessed. Participants were negative for Hepatitis B surface antigen and hepatitis C virus (HCV) RNA, with anti-HCV positive patients who achieved sustained virologic response after treatment included.

Investigating Forkhead Box O Transcription Factor 1 Gene's Relation to Immunoglobulin E in House Dust Mite-Allergic Asthma Patients.

House dust mite (HDM)-allergic asthma is an abnormal immune response to extrinsic aeroallergens found in human vicinities. Studying the role of the associated immunity biomarkers and their interplay helps in discovering novel therapeutic strategies that can be used in adjunct with effective long-term immunotherapy. This study investigates the total serum IgE, FoxO1, and Sirtuin 1 (SIRT1) gene expressions in HDM-allergic asthma patients.

Investigating the T regulatory cells and Sirtuin-I serum level in immunotherapy treated house dust mite allergic asthma patients.

Objectives: House dust mite aeroallergens are predominant triggers of frequent asthma attacks among adults and children. The intensity of asthma and immune reaction necessitates treatment alternatives based on adjusting chosen immunity biomarkers to control the exacerbation of symptoms and establish long-term immune tolerance. In this study, we selected CD4CD25Foxp3 regulatory T cells (Tregs), FOXP3, and Sirtuin-1 as they are known to have a potential role in the immune reaction in different allergic diseases.

Clinico-laboratory profile and perforin gene mutations of pediatric hemophagocytic lymphohistiocytosis cases: a five-year single center study.

Introduction: hemophagocytic lymphohistiocytosis (HLH) is an immunological disease characterized by hemophagocytosis of blood cells and proliferation of T-cells and histiocytes in the spleen and bone marrow then infiltration into body organs. Familial HLH (FHL) is a fatal disorder and determining gene mutations is a good guide for predicting the prognosis and choosing treatment options. This study aimed to illustrate the clinical, laboratory characteristics, including perforin gene mutation screening, treatment and survival outcome of pediatric HLH patients.

Efficacy of Montanide (IMS 3015) as an adjuvant for an inactivated Rift Valley fever (RVF) vaccine in sheep.

This study was conducted to evaluate an adjuvant, Montanide (IMS 3015), in improving the quality of Rift Valley fever (RVF) vaccine relative to the traditional adjuvant, aluminum hydroxide gel. Vaccinated sheep were evaluated using biochemical analysis, kidney function tests, liver function tests, and immunological tests. Sheep vaccinated with Montanide (IMS 3015) adjuvant showed significantly higher total protein, total globulin, and gamma globulin concentrations from the second week until the fifth month than the controls.

Corrigendum to "Spread of TEM, VIM, SHV, and CTX-M -Lactamases in Imipenem-Resistant Gram-Negative Bacilli Isolated from Egyptian Hospitals".

Impact of Some Ecological Factors on Fecal Contamination of Drinking Water by Diarrheagenic Antibiotic-Resistant in Zagazig City, Egypt.

Fecal contamination of drinking water is a major health problem which accounts for many cases of diarrhea mainly in infants and foreigners. This contamination is a complex interaction of many parameters. Antibiotic resistance among bacterial isolates complicates the problem.

Spread of TEM, VIM, SHV, and CTX-M β-Lactamases in Imipenem-Resistant Gram-Negative Bacilli Isolated from Egyptian Hospitals.

Carbapenem-resistant Gram-negative bacilli resulting from β-lactamases have been reported to be an important cause of nosocomial infections and are a critical therapeutic problem worldwide. This study aimed to describe the prevalence of imipenem-resistant Gram-negative bacilli isolates and detection of bla VIM, bla TEM, bla SHV, bla CTX-M-1, and bla CTX-M-9 genes in these clinical isolates in Egyptian hospitals. The isolates were collected from various clinical samples, identified by conventional methods and confirmed by API 20E.

Hepatitis C Virus NS5B Sequence-Based Genotyping Analysis of Patients From the Sharkia Governorate, Egypt.

Background: Chronic hepatitis C virus infection and its sequela are major health problems facing the Egyptian community. The high prevalence and spread rates of the disease require serious actions to stop or decrease these rates. Determination of HCV genotypes and subgenotypes adds significant knowledge about the epidemiology of the disease, and provides an added value in the decision making process of what strategy to follow and what therapy response to expect.

Evolutionary analysis of HBV "S" antigen genetic diversity in Iranian blood donors: a nationwide study.

The genetic diversity of the HBV S gene has a significant impact on the prophylaxis and treatment of hepatitis B infection. The effect of selective pressure on this genetic alteration has not yet been studied in Iranian blood donors. To explore HBV evolution and to analyze the effects and patterns of hepatitis B surface antigen (HBsAg) mutations on blood screening assays, 358 Iranian blood donors diagnosed as asymptomatic HBV carriers were enrolled in this nationwide study.
