It is known that adult growth hormone deficiency (GHD) is associated with oxidative stress (OS): both GH and IGF-1 exert antioxidant functions. OS is in turn related to systemic inflammation and cardiovascular/oncological risk. Discordant data concerning GH effects on antioxidants are reported. Moreover, no data are available in partial GHD, which can induce cardiovascular alterations. To evaluate oxidative damage on macromolecules and systemic inflammation, 80 patients, studi...

Background: The recently discovered myokin Irisin, a peptide originated by a proteolytic cleavage of the transmembrane protein fibronectin type III domain containing 5 (FNDC5) whose expression is induced by exercise and/or by increasing peroxisome proliferator-activated receptor (PPAR)-γ co-activator 1α (PGC-1α), has been considered a prognostic factor in Chronic Ischemic Cardiomyopathy and Acute Heart Failure. Nevertheless, no data are available on Irisin level...

Adult growth hormone deficiency (GHD), a condition characterized by increased oxidative stress (OS), is related to augmented cardiovascular, metabolic and oncological risk. Thymidine-glycol (ThyG) (5, 6-dihydro-5, 6-dihydroxy-2’-deoxythymidine) is a marker of DNA oxidation produced when thymidine is damaged by hydroxyl radicals. It is considered a specific marker since it is not incorporated in RNA; while 8-OH-deoxyguanosine, a well-known marker of oxidative damage, is ra...
