title: Pleiotropic effects of heparin and heparinoids in peritoneal dialysis.
abstract: Unfractionated heparin, low-molecular-weight heparins, and sulodexide belong to the family of glycosaminoglycans. Recent studies report on properties other than anticoagulant activities of these medications. They include modulation of cell growth and proliferation via actions on numerous growth factors affecting the immune system and matrix molecules production and degradation. Long-term peritoneal dialysis remarkably influences peritoneal cavity homeostasis by mechanisms mediated by growth factors. They initiate progression of pathological processes and further account for morphological and functional alterations of the peritoneal membrane. The best-recognized pathologies in peritoneal cavity under these conditions encompass inflammation, fibrosis, and vasculopathy, often leading to fatal encapsulating peritoneal sclerosis. Intraperitoneal heparin and its derivatives, by their pleiotropic actions, may influence these crucial processes and improve the peritoneal dialysis technique survival in a complex and so far understudied way. These issues, novel medical approaches, and their likely mechanisms have been reviewed.
