HSP, also known as anaphylactoid purpura and immunoglobulin A (IgA) vasculitis, is a small-vessel leukocytoclastic vasculitis characterized by the perivascular deposition of IgAl-based immune complexes in the walls of arterioles and postcapillary venules.
Inspiratory muscle weakness in patients with CHF is a result of a complex interplay between decreased total number of diaphragmatic actin-myosin cross-bridges (33), reduction in type IIb fibers (34), decreased regional blood flow, activation of the ubiquitin-protea-some proteolytic pathway by TNF-[alpha], decrease in various oxidative enzymes, size and number of mitochondria (35), atrophy of the limb muscle fibers, postcapillary pulmonary hypertension with compensatory vascular remodeling, bronchial congestion, decreased lung compliance and consequently increased work of the diaphragm up to threefold (36-37) and, to some extent, hyperpnea that could predispose to hyperinflation (38,39).
Among some of the proposed phenotypes are mixed precapillary and postcapillary PH, severe PH in respiratory disease, HIV-associated PH, portopulmonary hypertension, connective tissue disease-associated PH, and PAH in children.
mature, non-activated) lymphocytes migrate from the peripheral blood into lymph nodes and Peyer's patches by selectively interacting with the specialized endothelium of postcapillary venules called high endothelial venules (HEVs).
A postulated mechanism for necrotizing vasculitis in hepatitis C virus infection is a deposition of circulating immune complexes in postcapillary venules.
It could be due to the endothelial cell edema in the endothelium of postcapillary venules which cause obstruction in the blood flow and reduction in oxygen transport (Oliveira et al.
