Enteritis toxin accumulation. Ischemic enteritis is uncommon compared to ischemic colitis due to the highly vascularised nature of the small intestine, allowing for sufficient blood flow in most situations. It develops due to circulatory shock of mesenteric vessels in the absence of major vessel occlusion, often associated with an underlying condition such as hypertension, arrhythmia or diabetes. Thus it has been considered to be associated with atherosclerosis. Surgical treatment is usually required due to the likelihood of stenosis or complete occlusion of the small intestine. Ischemic damage can range from mucosal infarction, which is limited only to the mucosa; mural infarction
Neurogenic inflammation neuropeptides calcitonin gene-related peptide and substance P in sensory neurons," and so might be of use in treating diseases presenting with predominant neurogenic inflammation. In a 2012 article in "Nature Neuroscience" Chiu "et al." discuss the development of science related to neurogenic inflammation and provide a graphic illustrating key discoveries leading toward the current understanding of neurogenic inflammation, its mechanisms, and the conditions caused by its disorder. Neurogenic inflammation Neurogenic inflammation is inflammation arising from the local release by afferent neurons of inflammatory mediators such as Substance P, Calcitonin Gene-Related Peptide (CGRP), neurokinin A (NKA), and endothelin-3 (ET-3).
