The introduction of an ICD-10 code specific to IgG4-Related Disease offers a promising opportunity to revolutionize patient care, enable more accurate diagnoses, and improve outcomes.
Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory autoimmune disease characterized by tissue infiltration by dense lymphoplasmacytic infiltrate composed of T cells, activated B-cells, and plasma cells expressing IgG4 and has varied presentations with similar histopathology. It can involve visceral organs, glands, aorta, lymph nodes, and retroperitoneal tissue. In our case, a 68-year-old male with a past history of Hodgkin's lymphoma and in remission presented for investigation of polyclonal gammopathy. Serum electrophoresis showed increased free kappa light chains, free l...
Analyzing the clinical characteristics of patients tested for serum IgG4 because of suspecting IgG4-RD for a better understanding of the specific disorder.
In a recent study published in the journal PNAS, researchers demonstrated higher comparative efficacy of the intranasal (IN) route of coronavirus disease 2019 (COVID-19) vaccine administration versus intramuscular route in mice.

Early B cell signatures predict antibody responses to mRNA-based COVID-19 vaccine Researchers in the United States have identified both antigen-specific and antigen non-specific predictive signatures of antibody responses to Moderna’s two-dose coronavirus disease 2019 (COVID-19) vaccine that protects against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The team found that after both vaccine doses, robust and coordinated immunoglobulin A (IgA) and IgG responses were preceded by bursts of plasmablasts that are specific to the SARS-CoV-2 spike protein, although ...
