Pancreatitis in SLE remains an enigma and probably results from multiple pathogenetic mechanisms. However, cases of pancreatic thrombus formation remain few and far between, suggesting that APS is not the major cause of pancreatitis. Whether aPL contribute to pancreatic thrombus formation in rare patients needs to be demonstrated by antemortum arteriographic studies showing thrombus or vasculopathy. The postmortem pancreatic examination of patients who have died of the disseminated vasculopathy-coagulopathy syndrome remains problematic, because if thrombi are found, they may simply represent the endstage of multiple mechanisms, including hypotension, hypoxia, DIC, or TTP, rather than an aPL specific mechanism.

The plasma kallikrein-kinin system is activated in Gram-negative sepsis and typhoid fever, two diseases in which bacterial products have been shown to initiate inflammation. Because a single intraperitoneal injection of bacterial cell wall peptidoglycan-polysaccharide polymers from group A steptococci (PG-APS) into a Lewis rat produces a syndrome of relapsing polyarthritis and anemia, we investigated changes in the role of the kallikrein-kinin system in this model of inflammation. Coagulation studies after injection of PG-APS revealed an immediate and persistent decrease in prekallikrein levels. High-molecular-weight kininogen levels decreased significantly during the acute phase and correlated with the severity of arthritis. Factor XI levels were decreased only during the acute phase. Antithrombin III levels remained unchanged, indicating that neither decreased hepatic synthesis nor disseminated intravascular coagulation caused the decreased plasma contact factors. Plasma T-kininogen (an acute phase protein) was significantly elevated during the chronic phase. PG-APS failed to activate the contact system in vitro. Thus the kallikrein-kinin system plays an important role in this experimental model of inflammation, suggesting that activation of this system may play a role in the pathogenesis of inflammatory bowel disease and rheumatoid arthritis in which bacterial products might be etiologically important.
