Millions of individuals make illicit use of anabolic-androgenic steroids (AAS), remaining a public health issue. It often leads to detrimental effects, including cardiovascular and renal diseases, besides hormonal and metabolic imbalances. The objective of this review is to emphasize the contribution of oxidative stress and inflammation to these effects and connect the findings of experimental animal studies with the alterations found in clinical contexts, in AAS users. The study's results showed that AAS promotes a redox disruption and a pro-inflammatory state on organs that are involved in important physiologic processes. These drugs increase inflammatory high-sensitivity C-reactive protein (hs-CRP) and cytokines that contribute to the progression of atherosclerosis, cardiovascular disease risk or endpoints, including stroke, myocardial infarction and death. In the kidney, the AAS increase proteinuria and structural damage. Studies have linked AAS abuse with high BP, low HDL-C levels, high triglyceride levels and impaired fasting blood glucose that characterize Metabolic syndrome. Overall, the studies indicate that oxidative stress, apoptosis, and AAS-mediated inflammation play a significant role in tissue damage, regardless of the dose and duration of exposure, and we point it as a putative independent risk factor to Cardiovascular, Kidney and Metabolic syndrome.
