Autoimmune pancreatitis - An ongoing challenge

Area of Science:

• Gastroenterology
• Immunology
• Oncology

Background:

• Autoimmune pancreatitis (AIP) is a rare chronic pancreatitis subtype with multifactorial etiology involving genetic, environmental, and immunological factors.
• Type 1 AIP is associated with IgG4-related disease, presenting clinically with jaundice, abdominal discomfort, or asymptomatic forms.
• Diagnostic challenges include differentiating focal AIP from pancreatic cancer, where endosonography is crucial.

Purpose of the Study:

• To provide a comprehensive overview of autoimmune pancreatitis.
• To translate the latest scientific knowledge on AIP into clinical practice.

Main Methods:

• Review of existing literature on autoimmune pancreatitis.
• Analysis of diagnostic criteria including histology, imaging, serology, and response to therapy.
• Evaluation of treatment strategies, including corticosteroids, immunosuppressants, and surgical interventions.

Main Results:

• AIP diagnosis relies on a combination of histological, imaging, and serological findings, alongside clinical presentation and therapeutic response.
• Treatment involves corticosteroids and immunosuppressants, with potential need for endoscopic or surgical procedures.
• Relapses can occur even after recovery, and the link with malignancies requires further investigation.

Conclusions:

• Autoimmune pancreatitis requires a multidisciplinary diagnostic and therapeutic approach.
• Early treatment is essential, even in asymptomatic cases, to prevent long-term complications.
• Continued research is needed to clarify the relationship between AIP and malignancies.
