Living with Shwartzman phenomenon
A reaction in which inflammation damages small blood vessels, causing clotting and tissue damage.
Understanding Shwartzman phenomenon
It was first shown in rabbits given two doses of a bacterial toxin (endotoxin) about 24 hours apart. The inflammation damages small blood vessels, and clots then form in the capillaries and veins and cause tissue death. GARD says it can also occur during infections or pregnancy. How likely it is depends on the immune system, blood clotting and blood flow.
