		Hemolytic Uremic Syndrome									N	N
	Thromobcytosis	Thrombocytosis in response to acute or chronic inflammation has not been associated with an increased thrombotic risk. In fact, patients with markedly elevated platelet counts (>1.5 million), usually seen in the setting of a myeloproliferative disorder, have an increased risk of bleeding. This appears to be due, at least in part, to acquired von Willebrand disease (VWD) due to platelet-VWF adhesion and removal.
