Article Abstract
We herein report a rare case of autoimmune pancreatitis with small intestinal obstruction. A 72-year-old male was admitted to our hospital with abdominal fullness and vomiting and diagnosed with autoimmune pancreatitis by imaging and laboratory tests. Imaging studies also revealed narrowing of the proximal jejunum with dilated bowels and intramural cystic lesion adjacent to the pancreatic body. Small bowel resection was performed to alleviate stenosis. Pathological evaluation demonstrated invasion of IgG4-positive cells and fibrosis.

Introduction: Conventional dendritic cells (cDCs) in the gut express the vitamin A (VA)-converting enzyme retinal dehydrogenase 2 (RALDH2) and produce significant amounts of retinoic acid (RA). RA derived from gut cDCs contributes to the generation of tolerogenic responses by promoting Treg differentiation while inhibiting Th1 and Th17 cell differentiation. In this study, we investigated whether similar RA-mediated immunoregulatory mechanisms operate in the pancreas using an experimental autoimmune pancreatitis (AIP) model.

Double-filtration plasmapheresis is an advanced extracorporeal blood purification technique that selectively removes pathogenic macromolecules based on molecular weight. Unlike conventional plasma exchange, double-filtration plasmapheresis uses a two-step filtration process to retain beneficial plasma components such as albumin, while eliminating harmful substances, thereby reducing the need for exogenous plasma replacement. Over the last few decades, double-filtration plasmapheresis has gained prominence in the management of refractory autoimmune, neurological, metabolic, and renal diseases.

Background: Type 1 autoimmune pancreatitis (AIP) is more prevalent among males, a significant proportion of whom are known to smoke and consume alcohol, both of which can cause damage to the pancreas. AIP is associated with the new-onset impaired glucose metabolism (NO-IGM). However, it remains unclear whether smoking and alcohol consumption exacerbate this risk.

Etiology of childhood acute leukemia is largely unknown, though environmental factors and infection-related immune responses may contribute. Type 1 diabetes mellitus (T1DM), an autoimmune disease also with onset primarily in childhood, shares risk factors with leukemia, including childhood infection patterns. Epidemiological evidence suggests a link between T1DM and leukemia, but the extent of this association remains unclear.

We report a case of obstructive jaundice due to recurrent distal biliary stricture during 3 years of treatment for immunoglobulin G4 (IgG4)-related sclerosing cholangitis (IgG4-SC) associated with autoimmune pancreatitis. Although a relapse of IgG4-SC was initially suspected, imaging findings, laboratory tests, and histopathological examinations led to the diagnosis of metachronous cholangiocarcinoma. The patient underwent pancreaticoduodenectomy, and no cancer recurrence was noted 6 months postoperatively.
