High Dose Intravenous N-Acetylcysteine Versus Iloprost for Early, Rapidly Progressive Diffuse Systemic Sclerosis
January 29, 2007 updated by: Università Politecnica delle Marche
Rare Disease With Microvascular Involvement: High Dose Intravenous N-Acetylcysteine Versus Iloprost for Early, Rapidly Progressive Diffuse Systemic Sclerosis
- Systemic sclerosis (scleroderma; SSc) is a rare, disfiguring systemic disorder characterized by fibrosis of the skin and visceral organs that alters every aspect of an individual life
- Although some features of scleroderma phenotype are well established and represent the hallmarks of the disease, the primary cause is not fully delineated, though both endothelial cell damage, immunological abnormalities and excessive extracellular matrix production are well-documented
- Recently, excessive oxidative stress has been implicated in the pathogenesis of scleroderma
- N-acetylcysteine (NAC) exhibits direct and indirect antioxidant properties. Its free thiol group is capable of interacting with the electrophilic groups of ROS. This interaction with ROS leads to intermediate formation of NAC thiol, with NAC disulphide as a major end product. The net result is a decrease of the concentrations of OH-, H2O2, and HOCl. In addition, NAC exerts an indirect antioxidant effect related to its role as a glutathione (GSH) precursor. It serves as a central factor in protecting against internal toxic agents.
- In view of these considerations we expect that NAC can confer substantial benefit in patients with scleroderma reducing skin fibrosis in view of its antioxidant properties, and we have decided to conduct a double blind, multicenter trial to establish whether NAC could ameliorate skin fibrosis in scleroderma patients
