However, as these features are shared with systemic lupus erythematosus, cryoglobulinemia, or vasculitis including Wegener’s granulomatosis and Churg–Strauss syndrome, exclusion criteria were inserted Ilomastat in the next step. The third step was chosen to confirm an elevated serum IgG4 level, and the following step consisted of two
complementary components: radiologic and histopathologic examinations. If renal pathology was not available, a careful differential diagnosis to rule out malignant lymphoma, urinary tract carcinomas, renal infarction, pyelonephritis, Wegener’s granulomatosis [17, 18], sarcoidosis [19] and metastatic carcinoma was necessary, and non-renal histological finding with infiltrating IgG4-positive plasma cells >10/high power field (HPF) or IgG4/IgG >40% was necessary to support the radiologic findings. As the pathologic examination part, the following characteristic renal pathological findings of IgG4-RKD were listed: (a) marked lymphoplasmacytic infiltration, accompanied by >10 infiltrating
IgG4-positive plasma cells/HPF and/or a ratio of IgG4/IgG-positive plasma cells >40%, (b) characteristic fibrosis surrounding several infiltrating cells, (c) other useful findings for the differential diagnosis [positive findings: lesions extending into the renal capsule, eosinophil infiltration, well-defined regional lesion distribution, PD173074 cost marked fibrosis, negative findings: (necrotizing) angiitis, granulomatous lesion, neutrophil infiltration, advanced tubulitis]. Since about 80% of patients were diagnosed as having IgG4-RKD during the close examination of IgG4-related disease other than IgG4-RKD, an alternative pathway was inserted in the algorithm. Then, the performance of the diagnostic algorithm procedure was tested on these 41 patients with IgG4-RKD (Fig. 5). In this way, 38 of 41 patients (92.7%) were diagnosed with definite IgG4-RKD, two with suspected IgG4-RKD. In
contrast, none of the negative control patients were diagnosed with IgG4-RKD. Fig. 4 Diagnostic algorithm for IgG4-related kidney disease (IgG4-RKD).

However, even if the patient fulfills the classification criteria of lupus or vasculitis, this may not be sufficient to completely rule out IgG4-related disease, and measurement of serum IgG4 level is recommended in atypical cases 5.
