Current insight into enteropathogens in flare-up ulcerative colitis. An observational study.

Objective: Incidence of ulcerative colitis is globally increased. Enteric infections and their role in ulcerative colitis flares present a common health problem and a unique clinical challenge. We aimed to identify enteropathogens in flared ulcerative colitis patients and their antimicrobial susceptibilities and relation with the disease activity.

Clinical and Bacteriological Analyses of Biofilm-Forming Staphylococci Isolated from Diabetic Foot Ulcers.

Background: Diabetes mellitus is a chronic disease that is associated with increased morbidity and mortality. Unfortunately, foot ulcers and amputations due to diabetes are very common in developing countries. The purpose of this study was to characterize the clinical presentation of diabetic foot ulcer (DFU) infections, isolate the causative agent, and analyze the biofilm formation and distribution of biofilm-related genes among isolated Staphylococci.

Inetrleukin-6 and C-reactive protein as predictors of mortality among critically ill COVID-19 patients in Assiut university hospitals (ICUs).

COVID-19 represents a serious global threat due to scarcity of definitive cure and its infectious nature. The death rate of COVID-19 patients admitted to hospitals was quite high, and cytokine storms could be the mechanism of severity. Interleukin-6 (IL6) and C-reactive protein (CRP) may predict severity and mortality.

Hepatitis E Virus Persistence and/or Replication in the Peripheral Blood Mononuclear Cells of Acute HEV-Infected Patients.

Background: Hepatitis E virus (HEV) causes about 14 million infections with 300,000 deaths and 5,200 stillbirths worldwide annually. Extrahepatic manifestations are reported with HEV infections, such as renal, neurological, and hematological disorders. Recently, we reported that stool-derived HEV-1 replicates efficiently in human monocytes and macrophages .

Characterization of Antigen Escape Mutations in Chronic HBV-Infected Patients in Upper Egypt.

Background: Mutations within the "a" determinant region (position 124-147) that is present in the major hydrophilic region (MHR, position 99-160) of the hepatitis B surface antigen (HBsAg) are associated with vaccine-escape, lack of diagnosis, and failure to hepatitis B immunoglobulin (HBIG) therapy. Data regarding the amino acid changes of "a" determinant region of HBsAg are limited in Egypt. The prevalence and mutations in this region among chronic HBV (CHB)-infected patients in Upper Egypt are not known.

Evaluation of hepatitis E antigen kinetics and its diagnostic utility for prediction of the outcomes of hepatitis E virus genotype 1 infection.

HEV-Ag ELISA assay is a reliable diagnostic test in resource-limited areas. HEV genotype 1 (HEV-1) infections are either self-limited or progress to fulminant hepatic failure (FHF) and death if anti-HEV therapy is delayed. Limited data is available about the diagnostic utility of HEV Ag on HEV-1 infections.
