Aim: Detection of anti-HLA antibodies is crucial for pre-transplant histocompatibility testing, donor selection, and graft survival. The aim of this study was to evaluate the spectrum of anti-HLA antibodies among live related renal transplant recipients from one of the largest transplant centers in north India.
Methods: In this study, retrospective data of transplant workup done in past four years were analyzed using GraphPad Prism 9 Version 9.

Background: There is no robust evidence-based data for ABO-incompatible kidney transplantation (ABOiKT) from emerging countries.
Methods: Data from 1759 living donor ABOiKT and 33ā157 ABO-compatible kidney transplantations (ABOcKT) performed in India between March 5, 2011, and July 2, 2022, were included in this retrospective, multicenter (nā=ā25) study. The primary outcomes included management protocols, mortality, graft loss, and biopsy-proven acute rejection (BPAR).
Background: In this retrospective study, our aim was to find the effect of leucodepleted (LD) blood transfusions on the formation of anti-HLA-antibodies when compared to non-leucodepleted (non-LD) transfusions using Luminex-based method.
Methods: In this study, Luminex single antigen bead assay (L-SAB) and HLA typing were performed on 310 patients. Test positivity rates (as MFI - Mean florescence intensity) were analyzed according to the different sensitization events and gender.
Background: The main objective of this study was to determine the results of the cell-based assay (CDC-XM and FC-XM), and correlate with the results of solid phase assay (L-SAB).
Methods: In this retrospective study, 350 prospective renal transplant recipients were tested for the presence of HLA antibodies by CDC-XM, FC-XM and L-SAB screening with their corresponding donor.
Results: T-cell-FC-XM showed a sensitivity of 71.
Background: Patients awaiting solid organ transplantation may develop anti-HLA antibodies after sensitization events such as transfusions, pregnancies, or previous transplantations. However, the effects of a particular sensitization event on HLA alloimmunization have not been well studied in parallel using cell-based assays and solid-phase assays. In this study, we evaluated and compare how different sensitization events affect the HLA antibody screening (HLA-Ab) and donor specific antibody (DSA) status in solid renal organ transplantation patients.

Single antigen bead assay (SAB) is a semi-quantitative estimation of the amount of human leukocyte antigen (HLA) antibodies present in the recipient plasma, and mean fluorescence intensity (MFI) generated gives this rough estimation of the antibodies present in the recipient. Here we present a case of successful kidney transplantation in a patient who expressed DSA with high MFI.

However, the complexity of data from cell-based and solid phase assays have led to potential confusion about how to use the results for clinical decision making. </br></br> <b> Aim:</b> Aim of this study was to compare results of cell-based assay and solid phase assay, to evaluate the usefulness of L-XM for pretransplant detection of HLA class I and II donor-specific IgG antibodies, correlate the mean fluorescence intensity (MFI) values of class I and class II L-XM assay and with CDC-XM and L-PRA (panel reactive antibodies) results.

Materials And Methods: There were a total of seven clinically diagnosed cases of post partum thrombotic microangiopathies (PP-TMA) where PE was done.
Background And Aims: Although desensitization is well established, concerns about graft outcome, patient survival and rejection still exist. The present study aims at comparing outcomes of renal transplant recipients across simultaneous ABO and human leukocyte antigen (HLA) incompatibility barriers to those with ABO or HLA incompatibility alone.
Materials And Methods: This was a retrospective study conducted from October 2015 to December 2018.
Background And Aims: Preconditioning using different protocols has been tested to prevent antibody mediated rejection (ABMR) individually for ABO and HLA incompatibility. However, simultaneous presence of both barriers is still less explored. The aim of this study was to report outcomes of institutional desensitization protocol in renal transplant recipients with simultaneous ABO and HLA incompatibility.

Post consumed polyester clothes were recycled into bis(2-hydroxyethyl) terephthalate (BHET) monomer in the presence of ethylene glycol as depolymerising agent and zinc acetate as catalyst. Depolymerized product was characterized by chemical as well as analytical techniques.
