The Power of Keratinous Matrices (Head Hair, Body Hair, Nail Clippings) Analysis in a Fatal Intoxication Involving Anabolic Agents


 A 29-year-old man with no previous medical history was found dead at home. Anabolic products (tablets and oily solutions) and syringes were found at the scene. The man was known to train regularly at a fitness club and to use anabolic drugs. Following an unremarkable autopsy with normal histology, toxicological analyses were requested by the local prosecutor to provide further information. Blood, head hair (5 cm, black), body hair (axillary and leg), and toe and finger nail clippings were submitted to LC and GC–MS-MS methods to test for anabolic steroids. Blood tested positive for testosterone (4 ng/mL), boldenone (26 ng/mL), stanozolol (3 ng/mL) and trenbolone (< 1 ng/mL). Segmental head hair tests (2 x 2.5 cm) revealed a repeated consumption of testosterone (65–72 pg/mg), testosterone propionate (930–691 pg/mg), testosterone isocaproate (79 pg/mg–< 5 pg/mg), nandrolone decanoate (202–64 pg/mg), boldenone (16 pg/mg), stanozolol (575–670 pg/mg), trenbolone (4 pg/mg–not detected), drostanolone (112–30 pg/mg), drostanolone enanthate (26–5 pg/mg) and drostanolone propionate (15–4 pg/mg). In addition to the substances identified in head hair, testosterone decanoate, testosterone cypionate and nandrolone were identified in both body hair and nails. The experts concluded that the manner of death can be listed as toxic, due to massive repetitive use of anabolic steroids during the previous months. For anabolic agents, blood does not seem to be the best matrix to document a fatal intoxication. Indeed, these products are toxics when long term abused and are known to cause cardiac, hepatic and renal diseases. When compared to blood, hair and nails have a much larger window of detection. Therefore, keratinous matrices seems to be the best approach to test for anabolic steroids when a sudden death is observed in a context of possible abuse of steroids.
