Overcoming Electrochemiluminescence Immunoassay (ECLIA) Limitations: Conformation-Independent Quantitation of a Therapeutic Antibody by LC-MS/MS. (PubMed, Anal Chem) - "These findings highlight the need for alternative quantitation strategies in clinical settings, particularly when structural heterogeneity may compromise the ECLIA performance. Mass spectrometry provides a robust and reliable option for monitoring therapeutic antibodies under these conditions."

Comparison of clinical and histopathological features between serum IgG4-negative and serum IgG4-positive patients with type 1 autoimmune pancreatitis: A single-center, retrospective study. (PubMed, Cytojournal) - "Pathological examination remains critical (no serum-tissue IgG4 association). This study supports optimized, accurate diagnosis and stratified management of type 1 AIP."

Population Pharmacokinetics and Pharmacodynamics of Immunoglobulins: A Systematic Review. (PubMed, Clin Pharmacokinet) - "PopPK models have advanced understanding of IgG PK and its variability between patients and treatment regimens. These models provide a powerful framework to support individualised dosing strategies, thereby potentially reducing reliance on empirical, trial-and-error dosing approaches. However, clear target concentrations are lacking and must be established for individual patients. Models may be further optimised by incorporating essential Neonatal Fc receptor (FcRn) mechanisms using physiology-based pharmacokinetic (PBPK) or semi-mechanistic models. In conclusion, current models are useful to predict IgG concentrations across diseases during Ig treatment; however, a clearer relationship with PD is required. Hence, these findings can guide clinical trial design for tailored dosing regimens."

Hepatitis A serostatus and vaccination outcomes after on-campus education and point-of-care antibody testing. (PubMed, Front Public Health) - "These findings inform targeted young-adult hepatitis A prevention strategies by using on-site triage to focus counseling and referral on susceptible individuals and reduce reliance on off-site testing and return visits. Comparative studies are needed to assess the incremental value and cost-effectiveness of on-site testing and serostatus feedback."

Efgartigimod for Generalized Myasthenia Gravis and Beyond: A Narrative Review of Its Pharmacological Profile, Clinical Utility, and Expanding Applications. (PubMed, Biomedicines) - "Additionally, observational studies highlight its expanding utility in diverse IgG-mediated disorders such as immune thrombocytopenia (ITP) and autoimmune encephalitis. Efgartigimod thus represents a paradigm shift in autoimmune disease management, enabling precision immunomodulation with the potential for broad clinical impact and improved patient quality of life (QOL)."

Preparation of diatom frustules incorporated with protein A-fused C-terminal silica-binding peptide and interpenetrating polymer network for targeted drug delivery. (PubMed, World J Microbiol Biotechnol) - "Finally, tetracycline-incorporated diatoms exhibited an antibacterial activity against methicillin-resistant Staphylococcus aureus. Collectively, this study was a groundwork for further diatom-based antibiotic delivery paradigms in antimicrobial applications."

Effects of seaweed on blood plasma immunoglobulin concentration, mucosal immunity, small intestine histomorphology, cecal microbial population, and volatile fatty acid profile in broiler chickens. (PubMed, Vet World) - "The results suggest that BS and GS supplementation may serve as sustainable feed additives to enhance broiler performance while reducing reliance on synthetic supplements. Future studies should focus on identifying the bioactive compounds responsible for these effects and their broader implications for poultry production."

Immunoglobulin G subclasses confer protection against Staphylococcus aureus bloodstream dissemination through distinct mechanisms in mouse models. (PubMed, Proc Natl Acad Sci U S A) - "Thus, 3F6-based clearance of S. aureus in mice relies on a strain-specific contribution of variable FcγR- and complement-dependent pathways. We surmise that these variabilities are the result of genetic polymorphism(s) that may be encountered in other mammals including humans and may have clinical implications in predicting the efficacy of mAb-based therapies."

Fibrillary Glomerulonephritis and Monoclonal Gammopathy: Potential Diagnostic Challenges. (PubMed, Front Oncol) - "The discovery of DnaJ homolog subfamily B member 9 (DNAJB9) allows diagnosis for FGN with less reliance on EM, and the summary of recent studies revealed that genuine MGRS is extremely rare among FGN. Further research integrating IF-P, IgG subtyping, VH or VL domain monoclonality confirmation, and DNAJB9 as diagnostic modalities, with corresponding clinical data including treatment response and prognosis, is required for a better understanding of this subject."

Treatment of pemphigus vulgaris and foliaceus with efgartigimod, a neonatal Fc receptor inhibitor: a phase 2 multicentre, open-label feasibility trial. (PubMed, Br J Dermatol) - P2 | "Efgartigimod was well-tolerated and exhibited an early effect on disease activity and outcome parameters, providing support for further evaluation as a therapy for pemphigus. The study is registered at ClinicalTrials.gov (identifier: NCT03334058)."

Subcutaneous immunoglobulin treatment for chronic inflammatory demyelinating polyneuropathy. (PubMed, Muscle Nerve) - "SCIg preference may be a result of the independence and flexibility associated with self-infusion, whereas IVIg preference may be a result of familiarity and reliance on a healthcare professional for infusions. In practice, individualizing maintenance dosing based on disease behavior and determining the minimally effective IgG dose for individuals are key considerations irrespective of the administration route chosen."

SARS-CoV-2 Antibody Point-of-Care Testing in Dialysis and Kidney Transplant Patients With COVID-19. (PubMed, Kidney Med) - "Symptomatic dialysis patients and transplant recipients commonly develop an immune response against SARS-CoV-2 infection that can be detected using an LFIA. Used diligently, an LFIA could be used to help screen the dialysis populations or confirm exposure on a patient level, especially in facilities in which laboratory resources are limited."
