The analytical approach for detection of carbamylated erythropoietin for doping control purposes.

Erythropoietin (EPO) has protective effects in several tissues and could be used for therapeutic purposes, but the doses of EPO that can be beneficial in case of hypoxic-ischemic conditions due to overinduced erythropoiesis could be detrimental in treated patients. Carbamylation of erythropoietin maintains the tissue-protective effects of EPO but without erythropoietic effects. Carbamylated EPO (CEPO) is listed in WADA Prohibited List in class S2 as "Innate repair receptor agonists.

BUDESONIDE TREATMENT OF PROFESSIONAL ATHLETES AND ANTI-DOPING TESTING--CASE STUDIES.

According to the World Anti-Doping Agency (WADA) Prohibited List, glucocorticosteroids are prohibited in competition and only when administered by oral, intravenous, intramuscular or rectal routes. Up to now, in order to differentiate whether glucocorticosteroids were administered by one of the prohibited routes or not, a specific reporting limit for urinary concentrations of parent compounds and their metabolites was established at 30 ng/mL. Additionally, the new specific regulation starting from 1 September 2014 for budesonide have been introduced that the 6β-hydroxybudesonide shall be targeted.
