Primary Outcome Measures:
  • Clinical Response [ Time Frame: 6 months ]
    Clinical Response is measured by IgG4-RD Responder Index, including organ/site score and serum IgG4 level.


Biospecimen Retention:   Samples With DNA
blood samples (serum and plasma, with DNA)

Estimated Enrollment: 1000
Actual Study Start Date: January 2012
Estimated Study Completion Date: January 2032
Estimated Primary Completion Date: January 2032 (Final data collection date for primary outcome measure)
Groups/Cohorts
IgG4-RD
Patients with IgG4-RD, including sclerosing pancreatitis, sclerosing cholangitis, inflammatory pseudotumors, retroperitoneal or mediastinal fibrosis, interstitial nephritis, hypophysitis, sclerosing dacryoadenitis, sialadenitis (Mikulicz disease and Küttner's tumor), inflammatory aortic aneurysm, lymphadenopathy, or other inflammatory conditions.

Detailed Description:

Immunoglobulin G4-related disease (IgG4-RD) is a recently defined emerging clinical entity characterized by tissue infiltration by IgG4-positive plasma cells, tissue fibrosclerosis and elevated serum IgG4 concentration.

In this study, patients with IgG4-RD will be investigated, including clinical presentation, laboratory findings and imaging study. All patients will be treated by standard care and follow-uped for at least 6 months.
