简要总结
Autoimmune pancreatitis (AIP) is an autoimmune disease with low incidence rate and involving the pancreas. In China, type I AIP is predominant. Glucocorticoids (GC) have a significant therapeutic effect. Even though a consensus has been reached on the effective initial GC treatment dose, type I AIP is prone to recurrence after GC induction and maintenance therapy. Currently, there is no consensus on how to reduce the disease recurrence rate in high-risk type I AIP patients. Multiple studies have shown that immunosuppressants (IM) combined with GC can effectively reduce the disease recurrence rate in IgG4 RD patients, including azathioprine, mycophenolate mofetil (MMF), etc. Among them, the incidence of adverse reactions in MMF is relatively low. As a special type of IgG4-RD, there is currently no prospective study evaluating the efficacy and safety of GC combined with MMF treatment in high-risk recurrent type I AIP patients. The smooth implementation of this project can provide new treatment ideas and evidence-based medicine for reducing the recurrence rate of high-risk type I AIP.
详细描述
Autoimmune pancreatitis (AIP) is an autoimmune disease with low incidence rate and involving the pancreas. It can be divided into type I AIP and type II AIP. In China, type I AIP is predominant, accompanied by elevated IgG4 levels, diffuse or segmental pancreatic enlargement, and irregular narrowing of the pancreatic duct. Glucocorticoids (GC) have a significant therapeutic effect. Even though a consensus has been reached on the effective initial GC treatment dose, type I AIP is prone to recurrence after GC induction and maintenance therapy. Currently, there is no consensus on how to reduce the disease recurrence rate in high-risk type I AIP patients. The International Pancreatic Society has released an international consensus on AIP, indicating that the risk factors for AIP recurrence are still unclear. The following are possible signs of recurrence: IgG4>4 times the upper limit of normal value before treatment; The serum IgG4 level remained high after GC treatment; Pancreatic diffuse enlargement; IgG4-SC with proximal bile duct involvement; Involvement of extrapancreatic organs.Multiple studies have shown that immunosuppressants (IM) combined with GC can effectively reduce the disease recurrence rate in IgG4 RD patients, including azathioprine, mycophenolate mofetil (MMF), etc. Among them, the incidence of adverse reactions in MMF is relatively low. As a special type of IgG4-RD, there is currently no prospective study evaluating the efficacy and safety of GC combined with MMF treatment in high-risk recurrent type I AIP patients. The smooth implementation of this project can provide new treatment ideas and evidence-based medicine for reducing the recurrence rate of high-risk type I AIP.Main research objective: To evaluate the impact of corticosteroid monotherapy and corticosteroid combined with MMF maintenance therapy on disease remission rate in high-risk type I AIP patients with recurrence within 3 years Secondary research objective: (I) To evaluate the impact on endocrine function; (II) Evaluate the impact on external secretion function; (III) Evaluate the impact on the incidence of malignant tumors; (IV) Adverse reactions; (V) Treatment costs
