Carbapenem Resistance in Gram-Negative Bacteria: A Hospital-Based Study in Egypt.

The global spread of carbapenem resistance and the resulting increase in mortality forced the World Health Organization (WHO) to claim carbapenem-resistant (CRE) as global priority pathogens. Our study aimed to determine the prevalence of carbapenemase-encoding genes and major plasmid incompatibility groups among Gram-negative hospital-based isolates in Egypt. : This cross-sectional study was carried out at Mansoura University Hospitals over 12 months, from January to December 2019.

Evaluation of Rapid SARS-CoV-2 Antigen Detection as a Single Diagnostic Test and When Combined with C-Reactive Protein Level or Neutrophil to Lymphocyte Ratio in Suspected COVID-19 Subjects.

 Rapid antigen detection tests of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) play a crucial role in the control of the current coronavirus disease 2019 (COVID-19) pandemic. Data about the real diagnostic performance of such tests is still insufficient and hence their evaluation is of high priority.  The aim of this study was to evaluate the diagnostic performance of BIOCREDIT COVID-19 antigen test alone and in combination with either C-reactive protein (CRP) or neutrophil/lymphocyte ratio (NLR) in comparison to real-time quantitative polymerase chain reaction (RT-qPCR).

Effect of a combination of nitazoxanide, ribavirin, and ivermectin plus zinc supplement (MANS.NRIZ study) on the clearance of mild COVID-19.

This trial compared the rate and time of viral clearance in subjects receiving a combination of nitazoxanide, ribavirin, and ivermectin plus Zinc versus those receiving supportive treatment. This non-randomized controlled trial included 62 patients on the triple combination treatment versus 51 age- and sex-matched patients on routine supportive treatment. all of them confirmed cases by positive reverse-transcription polymerase chain reaction of a nasopharyngeal swab.

Diffusion-weighted magnetic resonance imaging and micro-RNA in the diagnosis of hepatic fibrosis in chronic hepatitis C virus.

Background: Diffusion-weighted magnetic resonance imaging has shown promise in the detection and quantification of hepatic fibrosis. In addition, the liver has numerous endogenous micro-RNAs (miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis.

Aim: To assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.

Diagnosis of cirrhosis in patients with chronic hepatitis C genotype 4: Role of ABCB11 genotype polymorphism and plasma bile acid levels.

Background/aims: Chronic hepatitis C (CHC)-related mortality generally results from cirrhosis and subsequent complications. We aimed to investigate the potential role of plasma bile acid levels and ABCB11 1331T > C (V444A, rs2287622) (ATP-binding cassette subfamily B, member 11) gene polymorphism in fibrosis prediction in CHC genotype 4 patients.

Materials And Methods: This case control study included 85 healthy control and the following 225 subjects: 170 adult patients infected with hepatitis C virus (HCV) and categorized into three groups according to liver biopsy; no fibrosis group (F0) (n=33), early fibrosis group (F1-F2) (n=61), and advanced fibrosis group (F3-F4) (n=76).

Role of serum (1,3)-β-d-glucan assay in early diagnosis of invasive fungal infections in a neonatal intensive care unit.

Objectives: To study the microbiological pattern of late onset neonatal sepsis cultures and to assess the diagnostic performance of serum (1,3)-β-d-glucan level for early diagnosis of invasive fungemia in high-risk infants admitted to a neonatal intensive care unit.

Methods: A prospective multicenter clinical trial conducted on infants at high risk for invasive fungal infections, with suspected late onset sepsis, admitted to a neonatal intensive care unit at Mansoura University Children's Hospital and Mansoura General Hospital between March 2014 and February 2016.

Results: A total of 77 newborn infants with high risk of invasive fungal infection were classified based on blood culture into three groups: no fungemia (41 neonates with proven bacterial sepsis), suspected fungemia (25 neonates with negative blood culture), and definite fungemia group (11 neonates with culture-proven Candida).

Prediction of Fibrosis Progression Rate in Patients with Chronic Hepatitis C Genotype 4: Role of Cirrhosis Risk Score and Host Factors.

The rate of liver fibrosis progression in chronic hepatitis C (CHC) patients is highly variable and affected by different factors. This study aimed to assess the role of cirrhosis risk score (CRS) based on 7 genetic variants (7 single-nucleotide polymorphisms [SNPs]) and host factors (age and sex) in the prediction of the rate of fibrosis progression in CHC. Duration of infection was determined in 115 patients.

Genetic Polymorphisms of Cytochrome P4501A1 (CYP1A1) and Glutathione S-Transferase P1 (GSTP1) and Risk of Hepatocellular Carcinoma Among Chronic Hepatitis C Patients in Egypt.

Cytochrome P450 1A1 (CYP1A1) and Glutathione S-transferase P1 (GSTP1) genes are involved in the metabolism of many carcinogens. Polymorphisms in these genes with altered enzyme activity have been reported. The present study evaluated the synergistic effect between CYP1A1 and GSTP1 gene polymorphisms and smoking on development of HCV-related liver disease and hepatocellular carcinoma (HCC).

Diagnostic Performance of an Immunoassay for Simultaneous Detection of Hcv Core Antigen and Antibodies among Haemodialysis Patients.

Nosocomial transmission of HCV is a concern in haemodialysis (HD) units worldwide. Diagnosis of HCV infection among dialysis patients is currently based on the detection of anti HCV antibodies by ELISA, and is confirmed by HCV RNA. The average window period between HCV infection and seroconversion with new generations of HCV antibody tests remains approximately 70 days with more prolonged period among dialysis patients.

Relation of Cag-A-positive Helicobacter pylori strain and some inflammatory markers in patients with ischemic heart diseases.

Recently, a potential link between infectious agents and athero-sclerosis has been suggested. H. pylori strains bearing the cytotoxin associated gene A (Cag-A) provoked a heightened inflammatory response in vivo and showed stronger relation to gastric complication of this infection.
