Case Report: Recurrent abdominal pain with elevated pancreatic enzymes in type 2 diabetes mellitus: a case of IgG4-related autoimmune pancreatitis misdiagnosed as acute pancreatitis
Clinical Scorecard: Case Study: Misdiagnosis of IgG4-Related Autoimmune Pancreatitis as Acute Pancreatitis in a Type 2 Diabetes Patient Presenting with Recurrent Abdominal Pain and Elevated Pancreatic Enzymes
At a Glance
Category
Detail
Condition
IgG4-related autoimmune pancreatitis (IgG4-AIP)
Key Mechanisms
Characterized by lymphoplasmacytic infiltration, fibrosis, and elevated serum IgG4 levels.
Target Population
Older males with a history of type 2 diabetes mellitus.
Care Setting
Hospitalization for diabetic complications and abdominal pain.
Key Highlights
IgG4-AIP often misdiagnosed as acute pancreatitis due to overlapping symptoms.
Elevated serum IgG4 levels are critical for diagnosis.
Timely glucocorticoid therapy can lead to symptom improvement.
Guideline-Based Recommendations
Diagnosis
Consider IgG4-AIP in T2DM patients with recurrent abdominal pain and elevated pancreatic enzymes unresponsive to AP treatment.
Utilize serum IgG4 measurement, imaging, and histopathology for diagnosis.
Management
Initiate glucocorticoid therapy upon diagnosis of IgG4-AIP.
Monitoring & Follow-up
Regularly assess serum IgG4 and pancreatic enzyme levels.
Risks
Misdiagnosis can lead to inappropriate treatment and delayed management.
Patient & Prescribing Data
Patients with IgG4-AIP and coexisting type 2 diabetes mellitus.
Glucocorticoid therapy is effective in managing symptoms and reducing IgG4 levels.
Clinical Best Practices
Integrate clinical, imaging, and laboratory findings for accurate diagnosis.
Be vigilant for atypical presentations of pancreatitis in diabetic patients.
