“…Among patient background factors, IgG4-related sclerosing cholangitis, obstructive jaundice, immune complex value, diffuse pancreatic ductal changes, and sclerosing sialadenitis have been proposed as relapse factors [ 6 , 15 – 18 ]. Studies of the serum IgG4 level have proposed the following predictive factors for relapse: high serum IgG4 at initial diagnosis [ 11 , 19 – 21 ], a high level before and after treatment [ 4 ], and resurgence of serum IgG4 in the remission phase after treatment [ 22 ].…”

“…Steroid pulse therapy for AIP is useful for subsequent evaluation of the therapeutic effect due to the absence of a need for tapering [ 11 ] and may also improve liver function (ALT, γ-GTP) and HbA1c [ 12 ]. Steroid pulse therapy was found to be effective in a patient with AIP in whom lower bile duct stricture did not improve after oral steroid therapy, and improved γ-GTP on a long-term basis in this patient [ 12 ].…”

“…However, the steroid dose tapering mostly used the methods referred to above and any deviation is likely to have had little influence on the results because all steroid doses during the period of serum IgG4 reduction did not differ significantly between the oral and pulse groups. As described above, steroid pulse therapy (mPSL 500 mg/day) is effective for therapeutic diagnosis of AIP [ 11 ]. We did not examine the effective dose of steroid pulse therapy (mPSL 125 or 250 mg/day) because all patients in the pulse group underwent steroid tapering.…”

“…Steroid pulse therapy produces local immunosuppression after organ transplantation and is effective for systemic lupus erythematosus (SLE), intestinal pneumonia, and several autoimmune diseases [ 8 – 10 ], but has not become established therapy for AIP. Matsushita et al suggested that steroid pulse therapy can be used for lower bile duct stricture and is useful for following the therapeutic outcome because of the lack of a need for tapering [ 11 ]. In 2011, Tomiyama et al reported significant improvements of γ-guanosine triphosphate (GTP) at 2 weeks after steroid pulse therapy, alanine aminotransferase (ALT) at 2 and 8 weeks, and glycosylated hemoglobin at 7 months after therapy [ 12 ].…”

Efficacy of Steroid Pulse Therapy for Autoimmune Pancreatitis Type 1: A Retrospective Study

et al. 2015

Autoimmune pancreatitis (AIP) is treatable with steroids, but relapse is frequent. The efficacy of steroid pulse therapy has been shown for various autoimmune diseases, but has not become established therapy. In this study, we reviewed the efficacy of steroid pulse therapy in 24 subjects who were diagnosed with AIP type 1 at our hospital. Patient characteristics, time-course of serum IgG4, and the cumulative relapse-free survival rate were compared between patients who received oral steroid therapy (oral group) and those who were treated with steroid pulse therapy (pulse group). Serum IgG4 was reduced significantly after therapy in both groups and the 5-year cumulative relapse-free survival rates in the two groups did not differ significantly (oral group 46.9%, pulse group 77.8%). However, in a subset of cases with diffuse pancreatic swelling, this rate was significantly lower in the oral group (33.3% vs. 100.0%, p = 0.046). These results suggest that steroid pulse therapy is effective for prevention of relapse in AIP patients with diffuse pancreatic swelling.

“…Aoki et al [9] reported a case of Mikulicz disease that was complicated by severe interstitial nephritis associated with IgG4 and successfully treated by methylprednisolone semipulse therapy. Moreover, some reports have shown that steroid pulse therapy is effective for the prevention of relapse in AIP patients [10] and that steroid pulse therapy is effective in reducing the maintenance dose in biliary stenosis caused by AIP [11].…”

Recently, as the number of case reports of IgG4-related kidney disease (IgG4-RKD) has increased, the histopathological features and clinical approach have been clarified. IgG4-RKD generally has a benign prognosis due to the efficacy of steroid therapy and rarely requires dialysis. Herein, we report a case of IgG4-RKD that presented with a subacute onset, advanced to end-stage kidney disease, and finally required maintenance hemodialysis despite steroid therapy. A 75-year-old man was admitted to our hospital for further evaluation of subacute renal failure. Diffuse enlargement of the kidney on computed tomography and increased urinary N-acetyl-β-D-glucosaminidase and α1-microglobulin levels led us to suspect IgG4-RKD. Upon admission, the laboratory serological findings were as follows: creatinine 3.3 mg/dL, urea nitrogen 46.9 mg/dL, and IgG4 235 mg/dL. Urinalysis showed slight proteinuria without hematuria. Percutaneous renal needle biopsy showed diffuse infiltration of abundant lymphocytes and IgG4-positive plasma cells and storiform fibrosis, which is specific to IgG4-RKD, in the interstitium on light microscopy. Slight linear deposition of C3 was also observed in the tubules on immunofluorescence microscopy, with no electron-dense deposits. He was definitively diagnosed as having IgG4-RKD and started on prednisolone 0.6 mg/kg/day. However, the renal insufficiency continued to progress and hemodialysis was necessary. As the prednisolone was tapered, renal function did not improve and maintenance hemodialysis was started. In conclusion, this case indicates that the prognosis of IgG4-RKD is not necessarily benign and that further studies involving more patients are needed.
