The role of intestinal ultrasound with colour Doppler in predicting the response to biologic therapy in inflammatory bowel disease patients.

Introduction: Inflammatory bowel disease patients are exposed to frequent procedures and hospital admissions as well as recurrent need for radiological examinations with a high risk of exposure to radiation and contrast.

Aim: Our objective was to evaluate the role of a combination of both intestinal ultrasound (IUS) and colour Doppler with different parameters for monitoring changes in inflammation over time and to reveal their potential role in the assessment of response to biologic therapy in inflammatory bowel disease (IBD) patients.

Material And Methods: Before the induction of biological therapy, IUS together with colour Doppler of the intestine was conducted.

High Incidence of Acute Liver Failure among Patients in Egypt Coinfected with Hepatitis A and Hepatitis E Viruses.

Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are transmitted through the fecal-oral route. HAV outbreaks and one HEV outbreak have been reported in Egypt. However, the impact of HAV-HEV co-infection is not known.

First Report on Abnormal Renal Function in Acute Hepatitis E Genotype 1 Infection.

Impaired renal functions have been reported with Hepatitis E virus (HEV) infections, especially with genotypes 3 and 4. These complications were reported during the acute and chronic phases of infection. HEV genotype 1 causes acute infection, and the effect of HEV-1 infections on renal functions is not known.

Characteristics and outcomes of acute hepatitis of unknown etiology in Egypt: first report of adult adenovirus-associated hepatitis.

Purpose: Several outbreaks of acute hepatitis of unknown etiology (AHUE) in children were reported in 2022 in many countries, with adenovirus identified as the etiological agent in most of them. We aimed to evaluate the characteristics and outcomes of AHUE cases in Egypt.

Methodology: Hospitalized patients with acute hepatitis were included in the study.

COVID-19 Infection in Patients with Comorbidities: Clinical and Immunological Insight.

Aim: Our study's objectives were to study the clinical and laboratory characteristics that may serve as biomarkers for predicting disease severity, IL-10 levels, and frequencies of different T cell subsets in comorbid COVID-19 patients.

Methods: Sixty-two hospitalized COVID-19 patients with comorbidities were assessed clinically and radiologically. Blood samples were collected to assess the T lymphocyte subsets by flow cytometry and IL-10 levels by ELISA.

Role of Serum Vitamin D, Interleukin 13, and microRNA-135a in Hepatocellular Carcinoma and Treatment Failure in Egyptian HCV-Infected Patients Receiving Direct Antiviral Agents.

Direct-acting antivirals (DAAs) are used for hepatitis C virus (HCV) treatment. However, treatment failure and hepatocellular carcinoma (HCC) development following treatment was reported. In this study, we assessed the role of serum vitamin D, interleukin 13 (IL-13), and microRNA-135a in the prediction of treatment failure with DAA and HCC development among Egyptian HCV-infected patients.

Interplay of Biochemical, Genetic, and Immunohistochemical Factors in the Etio-Pathogenesis of Gastric Ulcer in Rats: A Comparative Study of the Effect of Pomegranate Loaded Nanoparticles Versus Pomegranate Peel Extract.

Background: Few data are available about the role of herbal extract loaded nanoparticles as an alternative safe medicine for the management of a gastric ulcer.

Aim: This work is targeted at exploring the physiological effects of pomegranate loaded nanoparticles (PLN) against an indomethacin IND-induced gastric ulcer and comparing the results with traditional pomegranate peel extract (PPE).

Methods: Twenty-four rats were equally distributed into four groups: control, IND-treated, PLN-treated, and PPE-treated groups.

Clinical Outcomes and Prevalence of Hepatitis E Virus (HEV) Among Non-A-C Hepatitis Patients in Egypt.

Background: Hepatitis E virus (HEV) is an emerging infectious agent that causes acute hepatitis in developing and developed countries. Diagnosis of HEV infection has not been routinely done in Egyptian hospitals, and clinicians do not prescribe ribavirin (RBV) for acute hepatitis cases of unknown etiology (AHUE). We aimed to screen patients with AHUE for the presence of HEV markers and to determine the complications associated with HEV infection.

Interrelations of Apoptotic and Cellular Senescence Genes Methylation in Inflammatory Bowel Disease Subtypes and Colorectal Carcinoma in Egyptians Patients.

Ras-related domain family member 1 transcript variant A (RASSF1A) controls apoptosis and cell proliferation while p14/ARF gene has a regulatory role in cellular senescence. Failure of apoptosis and cellular senescence occurs during inflammatory bowel disease (IBD) and colorectal cancer (CRC). To reveal the role of peripheral leukocyte promoter methylation of RASSF1A and p14/ARF in the pathogenesis of IBD subtypes and CRC we investigated the methylation state of the two genes by methylation-specific polymerase chain reaction (MSP-PCR) in 60 CRC patients, 60 patients with IBD; 27 with ulcerative colitis and 33 had Crohn's disease and also in 30 healthy subjects.

Analysis of Lamin B1, Vimentin and Anti-Ku86 as Prospective Biomarkers of Hepatocellular Carcinoma in Patients with Hepatitis C Virus Infection.

Background/aims: Hepatocellular carcinoma (HCC) is the fifth most common malignancy and most frequently develops in patients with cirrhosis. Surveillance strategies are recommended in high-risk groups because early detection of small lesions improves the likelihood of curative treatment. This study investigated the prospective clinical significance of serum levels of anti-Ku86 and plasma levels of lamin B1and vimentin as early markers of HCC.

Pretreatment detection of circulating and tissue CD133 CD44 cancer stem cells as a prognostic factor affecting the outcomes in Egyptian patients with colorectal cancer.

Background And Aim: Colorectal cancer is one of the most common malignant tumors worldwide. As CD133 and CD44 are notable markers of cancer stem cells (CSCs) identity, it is thought to be a predictive indicator for colorectal cancer. The aim of this study was to investigate the cell cycle state of CD133 CD44 and CD133 CD44cells, isolated from primary human colorectal tumors, and to assess the clinical impact of CD133 CD44 CSCs on patients' outcome regarding disease-free survival (DFS) and overall survival (OS).

Frequency and Implications of Natural Killer and Natural Killer T Cells in Hepatocellular Carcinoma.

A complex role of the immune system has been highlighted in the development and progression of hepatocellular carcinoma (HCC). Natural Killer cells (NK) and natural killer T cells (NKT) cells are among the innate immune lymphocytes that predominate in the liver and can prevent tumor growth and metastasis. The aim of the study was to measure the percentages of NK and NKT cells among a sample of Egyptian patients with HCC and to find the association between their frequencies and disease progression.

Significance of biglycan and osteopontin as non-invasive markers of liver fibrosis in patients with chronic hepatitis B virus and chronic hepatitis C virus.

Several studies were performed to evaluate the degree of liver fibrosis by non-invasive markers. We aimed to assess the diagnostic value of both biglycan (BGN) and osteopontin (OPN) as non-invasive markers of hepatic fibrosis in patients with chronic hepatitis B (CHB) and chronic hepatitis C (CHC). This study was performed on 100 patients with CHB virus, 100 patients with CHC virus and 100 normal controls.

H. pylori infection increases gastric mucosal COX2 and mTOR expression in chronic gastritis: Implications for cancer progression?

Background: Helicobacter Pylori is a Gram-negative bacterium that infects the human stomach and plays an important role in the pathogenesis of chronic gastritis. H. pylori associated chronic gastritis affects various molecular markers related to gastric cancer development.
