Plasma glutathione levels are independently associated with ?-glutamyltransferase activity in subjects with cardiovascular risk factors

To investigate whether GGT (b.gamma-glutamyltransferase) is associated to specific redox patterns. GGT, total and reduced aminothiols and malondialdehyde, were measured in 150 subjects (83 males, 48 (39-56) years), with none, one or more risk factors. By univariable analysis GGT was positively associated with age (p =0.001), male gender (p 0.001), risk factor number (p 0.001), ACE-inhibitors (p
