Objectives Although elevated serum immunoglobulin A (IgA) levels are thought to exclude a
diagnosis of IgG4-related disease (IgG4-RD), IgG4-RD has been definitively diagnosed in …

Objective Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized
heterogeneous, subacute, and usually silent autoimmune disease involving many organs …

Patients with IgG4-related disease (IgG4-RD) often have elevated serum IgG4 levels. Here,
we aimed to evaluate the diagnostic performances of elevated serum IgG4 concentration …

Statement of Purpose. IgG4‐related disease (IgG4‐RD) is usually associated to an increase
of serum IgG4 levels. However other conditions have also been associated to high serum …

IgG4‐related disease (IgG4‐RD) is a recently described systemic fibroinflammatory disease
associated with elevated circulating levels of IgG4 and manifests a wide spectrum of clinical …

Immunoglobulin G4-related disease (IgG4-RD) is a newly emerging disease entity. IgG4-RD
is a systemic disease characterized by swelling or masses in the involved organs, elevated …

Objective: To elucidate the distribution characteristics of elevated serum immunoglobulin G4
(IgG4) and its relationship with immunoglobulin G4-related disease (IgG4-RD). Methods: In …

Objective Serum IgG4 concentrations are used to evaluate a diagnosis of IgG4-related
disease (IgG4-RD), but the positive predictive value (PPV) of a very high IgG4 level is …

Objectivse To explore the clinical characteristics and treatment efficacy of IgG4-related
disease (IgG4-RD) patients with different levels of serum IgG4. Methods A total of 299 …

Objective: This study was performed to better know diagnosis associated with serum IgG4
concentration, and to explore the possibility for development of a serum IgG4 for IgG4 …
