ABSTRACT
PURPOSE:
To clarify the clinical characteristics of autoimmune pancreatitis (AIP) in immunoglobulin (Ig)G4-related kidney disease (IgG4-RKD). PATIENTS ANDMETHODS:
A total of 92 patients with AIP were divided into an IgG4-RKD-positive group (RKD-P group, n = 13) and an IgG4-RKD-negative group (RKD-N group, n = 79) on the basis of the diagnostic criteria for IgG4-RKD. Clinical characteristics, including age; sex; the presence of extrapancreatic lesions other than renal lesions, proteinuria, and hematuria; serum concentrations of IgG, IgG4, IgE, and creatinine; and urinary concentrations of liver-type fatty acid binding protein, α1-microglobulin, ß2-microglobulin, and N-acetyl-ß-d-glucosaminidase were compared between the RKD-P and RKD-N groups. The clinical course of the RKD-P group was also characterized.RESULTS:
The prevalence of extrapancreatic lesions other than renal lesions was significantly higher in the RKD-P group (84.6% vs 43.0%,p < 0.01). Serum creatinine (1.19 mg/dl versus 0.74 mg/dl, p < 0.05), urinary ß2-microglobulin (6609.8 µg/l vs 265.8 µg/l, p < 0.05), and the prevalence of proteinuria (30.7% vs 7.6%, p < 0.05) were significantly higher in the RKD-P group. Nine out of thirteen patients in the RKD-P group had multiple low-density renal lesions on enhanced computed tomography, 3 patients had multiple high-intensity lesions on diffusion-weighted magnetic resonance images, and 1 patient had diffuse thickening of the renal wall, with a smooth intra-luminal surface.CONCLUSIONS:
Patients who had AIP with IgG4-RKD were more likely to have extrapancreatic lesions other than those in the kidney, and their serum creatinine and urinary ß2-microglobulin concentrations were significantly higher than in those without IgG4-RKD.Palabras clave
