7(th) International Immunoglobulin Conference: Poster presentations

Area of Science:

• Immunology
• Pharmacology
• Transplantation Medicine

Background:

• Immunoglobulin (Ig) therapy is a primary treatment for primary antibody deficiency disorders and various autoimmune/inflammatory conditions.
• Its role in complement activation is driving increased use in solid organ transplantation and immune-mediated neuropathies like CIDP and MMN.

Discussion:

• Trends in Ig therapy across Europe reveal availability challenges and varied dosing/administration routes, including subcutaneous immunoglobulin (SCIg).
• Optimization strategies for Ig therapy in neuropathies and primary antibody deficiency (PAD) are being explored, including individualized dosing and biomarkers like antigen-specific T cell responses.

Key Insights:

• Ig therapy mechanisms may involve immunoregulatory effects mediated by IgG antibodies against glycans.
• Potential thrombogenic adverse effects of Ig therapy require further investigation, despite being rare.
• Prophylactic IVIg decreased severe infections in heart transplant recipients with IgG hypogammaglobulinaemia.

Outlook:

• Further research is needed to clarify the relationship between Ig therapy, adverse reactions, and immunomodulatory effects.
• Individualized dosing strategies and biomarkers are crucial for optimizing Ig therapy outcomes.
• The role of Ig therapy in transplantation, particularly in managing infections and allograft survival, warrants continued study.
