In the past 5 years, the investigators of the "VECTOR" SRB VB and the L.A. Tarasevich State Institute of Standardization and Control of Medical Biological Preparations have jointly designed sera reference panels containing anti-HIV-1 IgG, anti-HCV IgG, and anti-HAV IgM which have been approved as national standard panels. The panels are intended for use in controlling the specificity and stability of the most widely used ELISA diagnostic kits and immunoblot test systems during production, control, and application stages. Some problems of development and production of these panels, including the representation of different sera in the panels and the selection of specific IgG concentrations in the different sera in the panel are described. The authors also attract attention to the stabilization of the specific characteristics of panel sera during storage and transportation.

Insights into proliferative glomerulonephritis with monoclonal immunoglobulin deposits - is it really monoclonal or not?

Curr Opin Nephrol Hypertens

January 2025

Control of the immune response B and lymphoproliferation, CNRS UMR 7276, INSERM UMR 1262, University of Limoges, Centre de référence de l'amylose AL et autres maladies par dépôts d'immunoglobuline monoclonale, Limoges, France; Service de néphrologie et Centre National de référence amylose AL et autres maladies à dépôts d'immunoglobulines monoclonales, Centre Hospitalier Universitaire, Université de Poitiers, Poitiers, France.

Purpose Of Review: Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMID), is a disease defined by the presence of glomerulonephritis with nonorganized mono-isotypic immunoglobulin (Ig) deposits. This review will discuss the pathogenesis of PGNMID and address novel techniques for detection of monoclonal Ig and pathologic B-cell clones and for distinguishing monoclonal from oligoclonal Ig deposits.

Recent Findings: Because of low detection rate of circulating monoclonal Ig and nephritogenic B-cell clones and emerging reports of PGNMID-IgG in children, it has been recently argued that many PGNMID-IgG3 cases may not be monoclonal lesions.

Molecular Characterization of Gene Encoding Outer Membrane Protein in Pathogenic Serovars in Iran.

J Trop Med

December 2024

Department of Microbiology, Agricultural Research, Education and Extension Organization (AREEO), Razi Vaccine and Serum Research Institute, Karaj, Iran.

The protein is highly conserved among pathogenic serovars and it is expressed during both acute and chronic infections. The aim of this study was to clone and sequence of the protein-encoding gene of serovars. In this study, 23 pathogenic serovars and two nonpathogenic serovars were used.

Background: The platelet-albumin-bilirubin (PALBI) grade is a comprehensive assessment index of liver function. Liver dysfunction is a key determinant of the pathogenesis and resolution of acute respiratory distress syndrome (ARDS), which affects the prognosis of patients.

Aims: To evaluate the association of PALBI grade with the risk of 30-day mortality in patients with ARDS.

BACKGROUND Although hypomagnesemia is common in type 2 diabetes, clinical presentations with severe hypomagnesemia are rare. A number of oral blood glucose-lowering medications can reduce serum magnesium concentrations, and several severe cases have been reported in the presence of marked glucagon-like peptide-1 receptor agonist (GLP-1RA)-associated gastrointestinal adverse effects. In the present case, an acute presentation with severe hypomagnesemia was likely due to polypharmacy including semaglutide, albeit with a delayed relationship to discontinuation of this GLP-1RA, due to nausea and vomiting.
