摘要: Human immunodeficiency virus (HIV)-related pulmonary hypertension (HRPR) is a cardiovascular complication of HIV infection that has been recognized in the last years with increasing frequency. The etiology HRPH unknown. All attempts to isolate on vessels patients failed, and an indirect role for this disease hypothesized. Current theories pathogenesis focus abnormalities endothelial smooth muscle cells vasculature. Endothelial cell injury could be due high production or reduced clearance cytokines these patients. In fact, several studies levels ET-1, IL-1alpha, IL-6 PDGF primary (PPH) have found. gp 120 induce by stimulation monocytes/macrophages. A alpha1-adrenoreceptors also implicated HRPH. Chronic hypoxia observed increased frequency patients, chronic alpha1-receptors vasculature typical pathological changes. However, only small percentage HIV- develop This observation suggests existence idiosyncratic susceptibility development vascular disease. genetic basis, might determined particular major histocompatibility complex alleles.
