Brief Summary:
This is an open-label study to investigate the diagnostic performance of 18F-FDG PET/CT (positron emission tomography/computed tomography) in evaluation of patients with IgG4-related disease. A single dose of 18F-FDG will be intravenously injected into patients with IgG4-related disease before and after treatment.

Condition or disease Intervention/treatment Phase
Autoimmune Disease Drug: 18F-FDG Early Phase 1

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. The most important feature of IgG4-RD is chronic inflammation with multiple organ involvement. However, some organ involvements are difficult to find by ultrasound, CT or MRI.

18F-FDG PET/CT is a sensitive imaging tool for inflammation. In this study, PET/CT were performed in patients with IgG4-RD both before and after glucocorticoid treatment by a single dose of 18F-FDG. Visual and semiquantitative method will be employed to assess the PET/CT images. The PET/CT image data will be used to establish a diagnostic model as well as assessment criteria for response evaluation of IgG4-RD treatments.

Arm Intervention/treatment
Experimental: 18F-FDG PET/CT scanning
18F-FDG PET/CT scanning will be performed in patients with IgG4RD to determine the pictorial characteristics and measure the standardized uptake values (SUVs) of the lesions and their response to treatment.
 Drug: 18F-FDG
Intravenous injection of single dose of 18F-FDG before treatment and after 4-week treatment, respectively.
Other Names:
  • 18F-Fluorodeoxyglucose
  • 2-Fluoro-2-deoxy-D-glucose
  • Fluorine-18-fluorodeoxyglucose


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Visual analysis of organ involvement and treatment response of the IgG4-RD patients. [ Time Frame: 1 year ]
    Visual analysis will be performed by consensus reading by at least 3 experienced nuclear medicine physician. The 18F-FDG PET/CT pattern of IgG4-RG will be extracted and summarized. The response to anti-immune treatment will be assessed.


Secondary Outcome Measures :
  1. Semiquantitative measurement of lesion metabolism and treatment response of the IgG4-RD patients. [ Time Frame: 1 year ]
    The semiquantitative analysis will be performed by measuring the standardized uptake values (SUVs) of 18F-FDG by the IgG4-RD lesions and calculate the SUV changes before and after anti-immune treatment.
