Autoimmune Pancreatitis

Abstract: SummaryAutoimmune pancreatitis (AIP) is a rare and underdiagnosed fibrosclerosing inflammatory variant of chronic pancreatitis. Its true incidence and prevalence in the general population is still not confirmed despite advances in medicine. Differentiating it from pancreatic cancer is of paramount importance. In this imaging review, we highlight the imaging findings of this intriguing entity.

“…The incidence of immune-related pancreatitis caused by ICIs is rare (CTLA4: 0.9–3%, PD-1: 0.5–1.6%, CTLA4 + PD-1: 1.2–2.1%) [ 6 16 ]. Since ICI-induced pancreatitis can be considered an immune-related pancreatitis, it is reasonable to propose that its diagnosis can be based on the diagnostic criteria of autoimmune pancreatitis (AIP) [ 26 , 27 ]; the diagnosis of autoimmune pancreatitis is based on results from these five factors: imaging, serology, histology, extrapancreatic involvement, and perhaps steroid responsiveness. Although the mechanism of immune-induced pancreatitis caused by ICIs is largely unknown, it is postulated that ICIs could unavoidably disturb the balance of autologous tolerance, which could result in some immune-related side effects.…”

“…No entanto, sua baixa disponibilidade e alto custo operacional inviabilizam a utilização rotineira desse exame. Outro fator limitante é a escassez de estudos com intuito de estabelecer a sua precisão diagnóstica na distinção entre PC e PAI (CAI; TAN, 2017;CONTI et al, 2021;SUREKA;RASTOGI, 2017). .…”

“…Type 1 is the pancreatic manifestation of a systemic Immunoglobulin G4-related disease (IgG4-RD); it is associated with increased IgG4 serum concentrations, lymphoplasmacytic infiltrate and phlebitis in the pancreas. Instead, type 2 AIP affects only the pancreas, has normal IgG4 serum concentration and, histologically, shows a neutrophilic inflammation [69]. Hereditary and environmental factors together are thought to induce adaptive immune responses to self-antigens [70].…”
