NCT ID:
NCT02703194
Eligibility Criteria:
Inclusion Criteria:
1. Age between 18 and 80 years.
2. Diagnosis of IgG4-RD according to either Consensus statement on the pathology of IgG4-related disease (for those who have undergone biopsies) or 2011 Comprehensive diagnostic criteria for IgG4-related disease. Both of the two criteria for diagnosis are specified below.
(1)Consensus statement on the pathology of IgG4-related disease
1. Histopathologic features consisting of dense lymphoplasmacytic infiltrate, fibrosis(usually storiform in character)and/or obliterative phlebitis within involved organs.
2. Either an elevated IgG4+/IgG+cell ratio of \>40% within the affected organs or elevated IgG4-bearing plasma cells per high-power field is necessary. The cut-off number of IgG4-bearing plasma cells per high-power field is different depending upon the types of affected organs and specimens(through surgery or needle puncture biopsy).
(2)2011 Comprehensive diagnostic criteria for IgG4-related disease
1. Clinical examination showing characteristic diffuse/localized swelling or masses in single or multiple organs.
2. Hematological examination shows elevated serum IgG4 concentrations(135 mg/dl).
3. Histopathologic examination shows marked lymphocyte and plasmacyte infiltration and fibrosis or Infiltration of IgG4+ plasma cells(ratio of IgG4+/IgG+ cells \> 40% and \>10 IgG4+ plasma cells/HPF).
Definite: a + b + c,Probable: a + c,Possible: a + b
4. Excluded from malignant tumors of each organ (e.g. cancer, lymphoma) and similar diseases (e.g. Sjögren's syndrome, primary sclerosing cholangitis, Castleman's disease, secondary retroperitoneal fibrosis, Wegener's granulomatosis, sarcoidosis, Churg-Strauss syndrome) by additional histopathological examination.
5. Even when patients cannot be diagnosed using the Comprehensive diagnostic criteria, they may be diagnosed using organ-specific diagnostic criteria for IgG4-RD, such as Diagnostic criteria for IgG4-Mikulicz's disease.
Exclusion Criteria:
1. Subjects having received steroids or immunosuppressants in recent 3 months will be excluded.
2. Subjects who were hypersensitive to leflunomide will be excluded.
3. ALT and/or AST is more than two folds of the upper limit of relevant reference value at baseline.
4. WBC is less than 3×10\*9/L at baseline.
5. Female patients who are pregnant or breastfeeding.
6. Known significant concurrent medical disease.
