Treatment-associated hemolysis in Kawasaki disease: association with blood-group antibody titers in IVIG products

Hemolytic anemia due to IV Immunoglobulin (IVIG) treatment can be a serious complication, especially for those with underlying conditions with a high degree of inflammation and after high-dose IVIG, such as Kawasaki disease (KD), a multisystem vasculitis that affects children. hemolysis is caused by antibodies against blood type A and B, but the exact mechanism is unknown to hemolysis.

We conducted a single center, partly retrospective, partly prospective cohort study of 581 patients who received IVIG for treatment of KD from 2006 to 2013. Factors associated with hemolysis identified through univariate and multivariate logistic regression. six IVIG preparations were tested for their hemolytic effect by serology and mobile to clarify the mechanism of destruction of red blood cells. During the study period, a sudden increase in the incidence of hemolysis is observed, which coincides with the introduction of the new IVIG preparations in North America that contain relatively high titers of anti-A and anti-B.

Blood antibody-specific groups are of immunoglobulin G2 (IgG2) subclass and resulted in phagocytosis by monocytes-derived macrophages with FcγRIIa-dependent manner. Phagocytosis increases with proinflammatory mediators that mimicked the inflammatory state of KD. Increased frequency of IVIG administration following severe hemolysis is caused by ABO blood IgG2 antibody-specific groups that led to the opening of FcγRIIa depending erythrocytes. Increased side effects requires a reconsideration of the criteria of maximum titer (1:64) anti-A and anti-B in the preparation of IVIG.

inter-laboratory study of peptide mapping workflow optimized automatic trypsin digestion using a monoclonal antibody to monitor product quality attributes

Peptide mapping analysis is the hope of rules to verify the primary structure of the sequence of the recombinant product and to monitor the post-translational modification (PTM). Although proteolytic digestion has been used for decades, it remains a labor-intensive procedure that can be challenging to accurately reproduce. Here, we describe a fast and reproducible protocol for automatic protease digestion using trypsin move on magnetic beads, which have been incorporated into the workflow optimized peptide mapping to show the transfer of all laboratory methods.

Complete workflow has the potential to be used in a multi-attribute approach method (MAM) in drug development, production and QC laboratories. Simple sample preparation workflow, suitable for experienced operators and have been studied extensively to demonstrate the global application and resilience to mAbs by digestion samples and LC-MS analysis in four independent locations in Europe. LC-MS / MS along with searching the database that is used to characterize protein and determining the relevant product quality attributes (PQAs) for further testing.

Description: CRK, also known as p38, is a protein that in humans is encoded by the CRK gene. This gene is a member of an adapter protein family that binds to several tyrosine-phosphorylated proteins. It is mapped to 17p13.3. The protein participates in the Reelin signaling cascade downstream of DAB1. The product of this gene has several SH2 and SH3 domains (src-homology domains) and is involved in several signaling pathways, recruiting cytoplasmic proteins in the vicinity of tyrosine kinase through SH2-phosphotyrosine interaction. The N-terminal SH2 domain of Crk functions as a positive regulator of transformation whereas the C-terminal SH3 domain functions as a negative regulator of transformation. Two alternative transcripts encoding different isoforms with distinct biological activity have been described.

List of relevant critical quality attributes (CQAs) is then formed by creating a workbook containing the specific peptide mass-to-charge (m / z) ratio of modified and modified peptides from CQAs selected, monitored in subsequent tests using LC-MS analysis. Data is provided which shows a strong digestive efficiency and low levels of induced PTM protocol. abstract graphics.
