چکیده

PURPOSE To investigate the relationship between immunoglobulin G (IgG)4-related disease (IgG4-RD) and thyroid eye disease (TED) with respect to IgG levels. PATIENTS AND METHODS A retrospective review of total IgG, IgG subclass, and thyroid stimulating immunoglobulin (TSI) levels in 24 patients with TED. RESULTS Five patients (20.8%) demonstrated serum IgG4 levels consistent with IgG4-RD without any additional systemic disease. Total IgG and IgG subclass levels were found to be an inadequate proxy for TSI elevation. CONCLUSION There may be a subtype of TED patients with elevated IgG4 in the absence of IgG4-RD systemic findings.

A study of serum IgG4 levels in the clinical metamorphosis of autoimmune thyroid disease

BACKGROUND Measurement of serum IgG4 had been suggested to distinguish the unique subtypes of autoimmune thyroid disease (AITD) which demonstrated patterns of fluctuating between hyperthyroidism and hypothyroidism. However, the clinical utility of serum IgG4 measurement is inconclusive due to few studies having addressed these unusual patients compared with the specificity of serum IgG4 in heal...

IgG4-related Hashimoto's thyroiditis--a new variant of a well known disease.

Hashimoto's thyroiditis (HT) has been characterized for many years as a well-defined clinicopathologic entity, but is now considered a heterogeneous disease. IgG4-related HT is a new subtype characterized by thyroid inflammation rich in IgG4-positive plasma cells and marked fibrosis. It may be part of the systemic IgG4-related disease. We report a case of a 56-year-old Portuguese man who presen...
