Summary
Primary sclerosing cholangitis can complicate with autoimmune pancreatitis, a rare condition. This autoimmune mechanism may respond to steroid therapy, offering new treatment avenues.
Area of Science:
- Gastroenterology
- Hepatology
- Immunology
Background:
- Primary sclerosing cholangitis (PSC) is a chronic liver disease.
- PSC commonly co-occurs with chronic pancreatitis.
- The autoimmune nature of this co-occurring pancreatitis is rarely explored.
Observation:
- Two cases of PSC with autoimmune pancreatitis (AIP) and pancreatic duct narrowing are presented.
- Both patients exhibited characteristic PSC findings on cholangiography.
- Autoantibodies, hypergammaglobulinemia, and pancreatic duct changes indicated AIP.
Findings:
- PSC complicated with AIP is a rare clinical entity.
- Reported cases suggest AIP in PSC may differ from typical AIP presentations.
- Ulcerative colitis was absent in reported cases, unlike typical PSC.
Implications:
- The autoimmune mechanism is significantly involved in PSC with AIP.
- Steroid therapy may be an effective treatment option for this complication.
- Further research is needed to understand this rare association.
