Correlation between rs7041 and rs4588 polymorphisms in vitamin D binding protein gene and COVID-19-related severity and mortality.

Background: The vitamin D binding protein (DBP) plays a critical role in both innate and adaptive immune systems, participating in several clinical conditions, including coronavirus disease 2019 infection severity, and mortality rate. The study aimed to investigate the correlation between rs7041 and rs4588 polymorphisms in the DBP gene and Coronavirus Disease-2019 (COVID-19) severity and mortality, in patients of Suez Canal University Hospitals in Ismailia, Egypt.

Methods: A case-control study enrolled 220 individuals; 140 COVID-19 patients and 80 healthy controls.

Clinical significance of viral markers testing by ELISA and Individual Donation Nucleic Acid Testing (ID-NAT) for blood screening in blood bank: Single center study in Egypt.

Prevention of transfusion-transmitted viral infections and insurance of safe blood transfusion are the main goals of all blood banks worldwide. Despite the high sensitivity and specificity of currently used enzyme linked immunosorbent assay (ELISA) for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) testing, viral transmission could still occur during the window period. Introducing viral individual donation nucleic acid testing (ID-NAT) can greatly decrease such risk providing an additional layer in securing blood transfusion.

Assessment of diagnostic and prognostic laboratory biomarkers in severe COVID-19 patients admitted to intensive care unit.

Coronavirus disease (COVID-19) is a global pandemic. In the first two years of the pandemic, nearly 15 million people died worldwide. Accurate and rapid laboratory diagnosis of COVID-19 infection is one of the milestones of pandemic control.

Neutrophil to lymphocytic ratio and other inflammatory markers as adverse outcome predictor in hospitalized COVID-19 patients.

Early risk classification of coronavirus disease 2019 (COVID-19) patients admitted to hospital is a critical key for providing optimal interventions. We investigated whether neutrophil-to-lymphocyte ratio (NLR) levels and other inflammatory and coagulation markers could be predictors for the severity and mortality of hospitalized COVID-19 patients. This cross-sectional study included 155 COVID-19 patients diagnosed by the reverse transcription polymerase chain reaction (RT-PCR) using oropharyngeal swabs.

Clinical significance of golgi protein-73 as a diagnostic marker for Egyptian patients with colorectal cancer: Preliminary study.

Background: Colorectal cancer is one of the most common cancers and the leading cause of cancer-related death worldwide. Early diagnostic methods help in therapeutic success and higher survival rate. Golgi protein 73 (gp73) could help in diagnosis of colorectal cancer at an earlier stage.

Cytotoxic T Lymphocyte Antigen 4 Gene +49 A/G (rs231775) Polymorphism and Susceptibility to Systemic Lupus Erythematosus.

Aim: To assess the probable role of +49AG polymorphism in susceptibility to SLE in an Egyptian population.

Background: Systemic lupus erythematosus (SLE) is a compound inflammatory chronic disease distinguished through the release of autoantibodies. Cytotoxic T lymphocyte associated antigen-4 is a main down controller of T-cell response; its dysregulation could affect SLE pathogenesis by altered T cells activation to self-antigens.
