Differentiating IgG4-related Sclerosing Cholangitis from Primary Sclerosing Cholangitis: A Comprehensive Systematic Review and Meta-analysis of Diagnostic Features

MWMark C. Wang ACAlbert C. Chong EGErick Cruz Grave

Key Points

The aim is to distinguish between IgG4-related sclerosing cholangitis and primary sclerosing cholangitis based on diagnostic features.
Conducted a systematic review and meta-analysis
Analyzed clinical, radiographic, and histological features
Evaluated the impact of elevated IgG4 levels and history of pancreatitis
IgG4-SC and PSC share similar clinical and radiographic features
A history of unusual pancreatitis is noted in patients with IgG4-SC
Elevated IgG4 levels can indicate a need for specific radiographic assessments

Abstract

Our meta-analysis shows that IgG4-SC and PSC present with similar clinical and radiographic features and possibly comparable histology. A history of unusual pancreatitis and elevated IgG4 (serum or tissue) prompt assessment for more specific radiographic features which if present warrant a therapeutic treatment trial.
