Autoimmune pancreatitis (AIP) is a steroid-responsive fibroinflammatory disorder with 2 clinically distinct subtypes known as type 1 autoimmune and type 2 autoimmune pancreatitis. Type 1 AIP is considered the pancreatic manifestation of immunoglobulin G4-related disease, a systemic disease often presenting with other organ involvement. Advances in understanding the unique clinical presentation, imaging findings, histopathology, and clinical course of this relatively uncommon disease have led to international consensus regarding diagnosis and treatment. While corticosteroids remain the mainstay of treatment, several emerging novel therapies have been explored primarily in the context or relapsing and refractory cases.

Background And Objectives: EUS is recommended for guiding pancreatic tissue acquisition in suspected autoimmune pancreatitis (AIP) cases. However, there is a lack of comparative research on the effectiveness between EUS-guided fine-needle aspiration (EUS-FNA) and EUS-guided fine-needle biopsy (EUS-FNB) for diagnosing AIP in China. This study aimed to evaluate the diagnostic accuracy of EUS-guided tissue acquisition (EUS-TA) specifically for type 1 AIP.

IgG4-related disease (IgG4-RD) is an autoimmune disease of unknown cause. is a transcription factor involved in immune responses, and its dysfunction leads to uncontrolled immune responses. We performed, to our knowledge, the first methylation analysis in type 1 autoimmune pancreatitis (denoted simply as AIP), a representative IgG4-RD.

Immunoglobulin G4-related disease (IgG4-RD) and systemic lupus erythematosus (SLE) are multisystemic autoimmune disorders that can present with renal manifestations. Overlapping cases of these diseases are extremely rare and present both diagnostic and therapeutic challenges. We report the case of a 70-year-old male with a history of autoimmune pancreatitis, who was admitted with fatigue, weight loss, and worsening kidney function.

Background: Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), can affect the hepatobiliary system and pancreas, substantially impacting the life quality of patients.
Objectives: To evaluate the quality of evidence and comprehensively assess the validity of associations of IBD with hepatobiliary and pancreatic diseases.
Design: We performed an umbrella review of existing meta-analyses in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) recommendations.
