Circulating immunoglobulin complexes in Wegener's granulomatosis
The American Journal of Medicine
|February 1, 1976
Summary
Circulating immunoglobulin complexes in Wegener's granulomatosis decreased with immunosuppressive treatment, alongside improvements in other disease markers. These changes may help monitor disease activity and treatment response.
Area of Science:
- Immunology
- Nephrology
- Rheumatology
Background:
- Wegener's granulomatosis is a systemic vasculitis affecting multiple organs.
- The role of circulating immune complexes in Wegener's pathogenesis is not fully understood.
Observation:
- Two cases of Wegener's granulomatosis were studied.
- Circulating immunoglobulin complexes were detected during active disease phases.
Findings:
- Immunoglobulin complexes, antiglobulin activity, and coagulation abnormalities decreased with immunosuppressive therapy.
- Serum complexes were immunoglobulin in nature, without DNA or cryoglobulins.
- Kidney biopsies showed fibrin deposition but no immune complex deposits.
Implications:
- Serial monitoring of immunoglobulin complexes and related markers may offer objective insights into Wegener's granulomatosis activity.
- These parameters could guide treatment decisions and assess therapeutic efficacy.
- Further research is needed to clarify the exact role of these complexes in pathogenesis.

Overview
01:10Antibody Structure
Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
