subclasses of IgG, is a surrogate marker for the recently characterized IgG4-related …

Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis that is characterized clinically
by frequent presentation with obstructive jaundice, histologically by a dense …

BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) and pancreatic cancer (PaC) have
similar presentations; a diagnostic strategy is needed to distinguish the 2 diseases …

pancreatitis. Systematic evaluation and management of AIP in the United States is reported …

Elevated serum immunoglobulin G4 (sIgG4) is a feature of autoimmune pancreatitis (AIP)
and IgG4‐associated cholangitis (IAC); a> 2‐fold increase in sIgG4 is considered highly …

Autoimmune pancreatitis (AIP) is a unique form of pancreatitis in which the pathogenesis is
suspected to involve autoimmune mechanisms. AIP sometimes mimics pancreatic cancer in …

Statement of Purpose. IgG4‐related disease (IgG4‐RD) is usually associated to an increase
of serum IgG4 levels. However other conditions have also been associated to high serum …

IgG4 is the least abundant subclass of IgG in normal human serum, but elevated IgG4 levels
are triggered in response to a chronic antigenic stimulus and inflammation. Since the …
