Filter by:The involvement of the kidneys in patients infected with the SARS-CoV-2 virus at the outset of the pandemic was associated with high mortality rates worldwide. This was in part due to the generation of an inflammatory process and exacerbated oxidative stress. The present study was initiated to investigate the relationship between morphofunctional changes and gene expression in the kidney tissue of deceased Mexican patients prior to the initiation of vaccination. The investigator designed a single-center, prospective, cohort study, to analyze and relate the morphofunctional changes and gene expression of inflammatory and oxidative stress molecules in the kidney tissue of men who died from severe COVID-19. A total of 40 percutaneous renal biopsies from deceased patients with SARS-CoV-2 infection were included in the study and divided into two a groups. One group was preserved in trizol to obtain RNA and total protein, while the remaining sample was fixed in formalin to be examined by staining with hematoxylin and eosin. The histopathological analysis was conducted by an experienced nephropathologist. The expression of molecules was evaluated by real-time PCR (nphs2, slc9a1, cx3cl1, havcr1, slc22a17, sod2, egf, timp2, hmox1, fabp1, and so forth). The following biomarkers were analyzed: IL-6, Arg-1, DPP4, GSTT1, GGT1, OCL, CYP3A4, and CL-8. Additionally, Western blot analysis was conducted on claudins-5, occludin, HSP70, NRF-2, SOD2, NQO1, γ-GCL, and RAGE. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI (2021) equation, with the subjects divided into two groups based on their eGFR: >60 or <60 ml/min/1.73 m². The statistical analysis was conducted using the Stata program and GraphPad Prism software.
In our study, some inflammatory Interleukin-2 , Interleukin-6, Interferon-γ, Tumor Necrosis Factor-α and anti-inflammatory Interleukin-4 and Interleukin-10 cytokine genes expressions and Triggering Receptor Expressed On Myeloid Cells- 1, which contributes to the pathology of acute and chronic inflammatory diseases; Human Leukocyte Antigen-G5, which suppresses the immune response; the expression levels of transcription factor Forkhead box-P3 expressed in regulatory T-lymphocytes and Cluster of Differentiation (CD)14 genes, which are thought to be biomarkers in various infectious diseases and expressed in monocytes, will be measured from peripheral blood samples obtained from liver transplant patients before, 1 month and 6 months after the operation. In addition, the classical liver markers Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Platelet Count (PLT), Alpha Feto Protein (AFP), Direct Bilirubin (Bilirubin D), Total Bilirubin (Bilirubin T) and C- Levels of biochemical parameters such as Reactive Protein (CRP) will be measured. In the light of the data to be obtained, it is aimed to find biomarkers with high predictive value for rejection and infection after liver transplantation.
The aim of this work is Detection of gram-negative isolates from different clinical samples,determination the antimicrobial susceptibility pattern of gram-negative isolates to various antimicrobial agents, Molecular Detection of blaNDM-1 and blaKPC gene among gram-negative isolates by PCR, Molecular Detection of blaNDM-1 and blaKPC gene among gram-negative isolates by LAMPand,evaluation the use of the LAMP assay for rapid and cost effective detection of the blaNDM-1 and blaKPC gene among gram-negative isolates in comparison with PCR.
