Background And Study Aims: Hepatitis C virus (HCV) infection is a significant problem in Egypt, as it is associated with various hematological disorders, both benign and malignant. In Egypt, direct-acting antivirals (DAAs) serve as the principal therapy for HCV to achieve a sustained virological response (SVR). This study investigated the effects of sofosbuvir (SOF) and daclatasvir (DCV) on HCV patients with benign blood index abnormalities and examined the correlation between these abnormalities and SVR.

Background: Non-alcoholic fatty liver disease (NAFLD) involves abnormal fat accumulation in the liver, mainly as triglycerides. It ranges from steatosis to non-alcoholic steatohepatitis (NASH), which can lead to inflammation, cellular damage, liver fibrosis, cirrhosis, or hepatocellular carcinoma (HCC). Long non-coding RNAs (lncRNAs) are crucial for regulating gene expression across various conditions.

Background: Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD) characterized by damage and inflammation of hepatocytes. Some medicinal plants have shown antioxidant and anti-inflammatory effects on liver cells. We aimed to investigate the hepatoprotective effect of Heptex® capsules containing 200 mg of Dukung Anak (a powdered extract from aerial parts of Phyllanthus niruri) and 100 mg of Milk Thistle (a powdered extract from fruits of Silybum marianum) in patients with an apparent risk factor for NASH.

Role of IL-6, TNF-α and VCAM-1 as predictors of renal impairment in patients with spontaneous bacterial peritonitis.

Trans R Soc Trop Med Hyg

January 2025

Endemic Medicine and Hepato-Gastroenterology Department, Faculty of Medicine, Cairo University, Cairo 3753450, Egypt.

Background: Multiple mechanisms may contribute to the occurrence of renal impairment (RI) in patients with spontaneous bacterial peritonitis (SBP). One such mechanism is systemic inflammatory response syndrome, which involves the release of pro-inflammatory cytokines (tumour necrosis factor [TNF]-α, interleukin [IL]-6 and vascular cell adhesion molecule [VCAM]-1). The goal of this research was to evaluate the role of IL-6, TNF-α and VCAM-1 as potential predictors of RI and mortality in cirrhotic patients with SBP.

Background: Viral hepatitis B and C are the leading causes of hepatocellular carcinoma (HCC). With obesity, metabolic-related disorders are increasingly associated with a higher incidence of nonviral HCC. This study aimed to investigate the characteristics, tumor features, treatment outcomes, and survival of patients with viral versus nonviral HCC.

Role of macroscopic on-site evaluation of endoscopic ultrasound-guided fine-needle aspiration/biopsy: Results of a multicentric prospective study.

World J Gastrointest Endosc

November 2024

Department of Gastroenterology and Endoscopy Center, Cheikh Khalifa International University Hospital, Mohammed VI University of Sciences and Health, Casablanca 82403, Casablanca-Settat, Morocco.

Article Synopsis
  • The study evaluates the effectiveness of macroscopic on-site evaluation (MOSE) during endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) in diagnosing solid lesions, particularly focusing on histological core sample adequacy.
  • Conducted across 16 medical centers in Egypt, Iraq, and Morocco, the study involved over 1000 patients and revealed that a significant majority of biopsied samples were adequate for histological evaluation, demonstrating a high diagnostic yield.
  • Results indicated that FNB needles performed best in terms of sensitivity and sample quality, highlighting the potential of MOSE as a valuable alternative to traditional rapid on-site evaluation methods.

Magnetite nanoparticles have attracted the attention of researchers for biomedical uses, but their impacts on the reproductive system did not report. Here, we have studied the possible attenuation efficiency of quercetin against magnetite nanoparticles-induced apoptosis in ovarian. Forty female rats were divided equally into control, quercetin (100 mg/kg), magnetite nanoparticles (50 mg/kg), and magnetite nanoparticles+quercetin, where all rats received their doses for four weeks.

  • * Recent efforts to stop smoking haven't been put into action yet, and it’s important to see what could happen if smoking rates stay the same or improve.
  • * Researchers used models to predict health outcomes by 2050 based on different scenarios of smoking rates, showing that cutting smoking could greatly improve health and life expectancy.

: Endoscopic biliary plastic stenting is a safe and effective temporary therapeutic modality used in various benign biliary disorders. Long-term indwelling stents for more than one year without retrieval are termed "forgotten biliary stents". In clinical practice, the forgotten stents are underestimated and the majority of data were obtained from case reports.

Background: Despite the success of sleeve gastrectomy (SG) in of weight loss and treatment of the medical problems associated with obesity, some concerns have arisen about the need for revisional surgeries after SG in some patients. This study aimed to present an updated and comprehensive comparison among the presently available revisional surgeries employed explicitly in cases of inadequate outcomes after SG, which is the most frequently performed bariatric surgery in contemporary practice.

Methods: This network meta-analysis included studies that compared the outcomes of different revisional bariatric procedures after an inadequate outcome of SG.

Background: Hepatocellular carcinoma (HCC) arises from hepatocytes and accounts for 90% of primary liver cancer. Reasons for HCC prognosis remaining dismal are that HCC is asymptomatic in its early stages, leading to late diagnosis, and it is markedly resistant to conventional chemo- and radiotherapy. In this study, we investigated RNA interference (RNAi)-based treatment for HCC by targeting MDK.

Background: Type I diabetes mellitus (T1DM) is one of the most common chronic autoimmune diseases worldwide. miRNAs are a class of small non-coding RNA molecules that have been linked to immune system functions, β-cell metabolism, proliferation, and death, all of which contribute to pathogenesis of TIDM. Dysregulated miRNAs have been identified in Egyptian TIDM patients.

Introduction: Diagnosis of the majority of hepatocellular carcinoma (HCC) patients occurs at intermediate to advanced stages, with a few curative therapeutic options being available. It is therefore strongly urgent to discover additional adjuvant therapy for this lethal malignancy. This study aimed to assess the effectiveness of curcumin (C), piperine (P) and taurine (T) combination as adjuvant agents on serum levels of IFN-γ, immunophenotypic and molecular characterization of mononuclear leukocytes (MNLs) in HCC patients treated with Transarterial chemoembolization (TACE).

: Functional gastric stenosis, a consequence of sleeve gastrectomy, is defined as a rotation of the gastric tube along its longitudinal axis. It is brought on by gastric twisting without the anatomical constriction of the gastric lumen. During endoscopic examination, the staple line is deviated with a clockwise rotation, and the stenosis requires additional endoscopic manipulations for its transposition.
