Anabolic androgenic steroid-induced hepatotoxicity

Area of Science:

• Toxicology
• Hepatology
• Endocrinology

Background:

• Anabolic androgenic steroids (AAS) are frequently abused by athletes to enhance performance and muscle mass.
• AAS abuse is associated with significant adverse health effects, particularly hepatotoxicity.
• Hepatotoxic effects include cholestatic icterus, peliosis hepatis, and hepatocellular carcinoma/adenoma.

Purpose of the Study:

• To propose a hypothesis for the mechanism of AAS-induced hepatotoxicity.
• To investigate the role of oxidative stress in AAS-induced liver injury.
• To differentiate the hepatotoxic potential between 17α-alkylated and nonalkylated AAS.

Main Methods:

• Literature review and synthesis of existing research findings.
• Formulation of a hypothesis based on observed associations.
• Analysis of the biochemical properties of 17α-alkylated AAS related to bioavailability and metabolism.

Main Results:

• 17α-alkylated AAS are specifically linked to hepatotoxicity, unlike nonalkylated AAS.
• The 17α-alkylation enhances oral bioavailability by retarding hepatic metabolism.
• Oxidative stress is consistently observed in association with AAS-induced hepatotoxicity.

Conclusions:

• A potential mechanism for AAS-induced hepatotoxicity involving oxidative stress is proposed.
• 17α-alkylated AAS present a higher risk of liver damage due to their metabolic profile.
• Further research is warranted to elucidate the precise molecular pathways of AAS hepatotoxicity.
