Background: The use of performance-enhancing drugs has increased dramatically in the last decade with high prevalence reported among the young athlete population. Many of these drugs contain anabolic steroids and may carry potential significant side effects and health risks. We report a case of anabolic steroid-induced acute pancreatitis (AP) that recurred after the reuse of the same drug by the patient, confirming the causative relationship.

Case report: A 24 year-old male presented with severe epigastric pain. His past medical history was significant for two hospitalizations during the last year with AP. During his hospital admissions, extensive workup was performed ruling out the common and uncommon causes of AP. Upon further pressing, the patient admitted to a history of past and current anabolic steroid use for athletic performance enhancement. He began this use four years ago and most recently started using trenbolone acetate (TA). The correlation between the timing of the anabolic steroids administration and the attacks of AP, along with ruling out other causes, confirmed TA as the cause of pancreatitis.

Discussion: The side effects associated with the use of these increasingly prevalent drugs are difficult to study in clinical trials due to the unethical nature of their consumption. In addition, these medications are difficult to study due to the varied usage cycles and patterns, unknown origin and source, as well as often high dose ingestion. Physicians and body builders need to be aware of the possible serious consequences of their use.

A 34-year old male was found breathless and panting at home by his girlfriend three hours after a gym workout. Minutes later, he collapsed and died. Autopsy, histological and chemical analyses were conducted. The examination of the heart showed left ventricular hypertrophy, while the right coronary artery showed only a small vascular lumen (3 mm in diameter), due to its anatomical structure. In femoral blood concentrations of approx. 1 μg/L clenbuterol, approx. 56 μg/L stanozolol and approx. 8 μg/L metandienone, with trenbolone (<limit of quantification (LOQ)) were detected. Additionally, there were positive results in urine for boldenone, clomiphene, trenbolone, metandienone, stanozolol, clenbuterol and drostanolone, along with indications of testosterone and/or testosterone prohormones having been taken. In consideration of all aspects of this case, in can be assumed that the long-term consumption of anabolic androgen steroids (AAS) caused apparently pathological changes of the heart. Over and above, the combination of anatomical (small lumed coronary artery, ventricular hypertrophy) and substance-induced risk factors led to the fatal cardiovascular failure.

Trenbolone is a synthetic anabolic-androgenic steroid, which has been misused for performance enhancement in sports. The detection of trenbolone doping in routine sports drug testing programs is complex as methods utilizing gas chromatography/mass spectrometry are complicated by unspecific derivatization products and artifacts, and liquid chromatography/mass spectrometry-based assays have shown to allow for comparably high limits-of-detection only. The number of previously reported metabolites in human urine is limited, and most analytical methods rely on targeting epitrenbolone, trenbolone glucuronide, and epitrenbolone glucuronide. In order to probe for the presence of additional trenbolone metabolites and to re-investigate the metabolism, an elimination study was conducted. One single dose of 10 mg of 5-fold deuterated trenbolone was administered to a healthy male volunteer and urine samples were collected for 30 days. For sample processing, published protocols were combined considering unconjugated, glucuronic acid-, sulfo- and alkaline-labile conjugated steroid metabolites. The sample preparation strategy consisted of solid-phase extractions, liquid-liquid extractions, metabolite de-conjugation, HPLC fractionation, and derivatization. Analytical methods included gas chromatography/thermal conversion/hydrogen isotope ratio mass spectrometry combined with single quadrupole mass spectrometry as well as liquid chromatography/high accuracy/high resolution mass spectrometry of the hydrolyzed and non-hydrolyzed samples. Twenty deuterium-labeled metabolites were identified including glucuronic acid-, sulfo- and potential cysteine-conjugates, and characterized by parallel reaction monitoring experiments yielding corresponding product ion mass spectra. Main metabolites were attributed to trenbolone-diol and potential trenbolone-diketone derivatives excreted as glucuronic acid and sulfo-conjugated analytes with detection windows of 5, respectively 6 days. Further characterization was conducted with pseudo MS3 experiments of the intact conjugates and by comparison of resulting product ion mass spectra with reference material.

We describe a case of a 21-year-old male bodybuilder who overdosed on Parabolan (trenbolone acetate) because of its anabolic activity. The patient, with no previous medical history, experienced pruritus and yellow discoloration of the skin and sclerae. Basic biochemical laboratory examination revealed signs of cholestasis with a serum bilirubin level of up to 65.5 mg/dl. Because supportive medical treatment was ineffective, the patient was treated with the molecular adsorbent recirculating system (MARS). Five MARS cycles lasting from 8 to 12 hours were performed every second day. The procedure was well tolerated by the patient and resulted in a sustained relief of pruritus. At the 2-month follow-up visit the plasma bilirubin level had decreased to 2 mg/dl.

Background: Anabolic androgenic steroids (AAS) usage is widespread and increasing. AAS drug-induced liver injury (DILI) is recognised but its clinical course and management is poorly described. We report 2 cases of AAS DILI with associated renal dysfunction, managed successfully with oral corticosteroids.

Methods: A comprehensive review identified 50 further cases to characterise the clinical and biochemical course. Causality grading was calculated using the updated Roussel Uclaf Causality Assessment Method (RUCAM) score. Data are presented as median values.

Results: The most common AAS taken was methyldrostanolone. Patients commonly present with jaundice and pruritus but may exhibit other constitutional symptoms. Patients presented 56 days after starting, and bilirubin peaked 28 days after stopping, AAS. Causality assessment was 'unlikely' in 1 (2%), 'possible' in 31 (60%) and 'probable' in 20 (38%). Peak values were: bilirubin 705 μmol/L, alanine transaminase 125 U/L, aspartate transaminase 71 U/L, alkaline phosphatase 262 U/L, gamma-glutamyl transferase 52 U/L, international normalised ratio 1.1. Liver biopsies showed 'bland' canalicular cholestasis. 43% of patients developed kidney injury (peak creatinine 225 μmol/L). Therapies included antipruritics, ursodeoxycholic acid and corticosteroids. No patients died or required liver transplantation.

Conclusions: Physicians are likely to encounter AAS DILI. Causality assessment using the updated RUCAM should be performed but defining indications and proving efficacy for therapies remains challenging.

Thyrotoxic periodic paralysis in a competitive bodybuilder with thyrotoxicosis factitia

Thyrotoxic periodic paralysis in a competitive bodybuilder with thyrotoxicosis factitia / Amy J. Patel, Stephanie Tejera, Stanislaw P. Klek, Gary D. Rothberger. - (AACE Clinical Case Reports 6 (2020) 5 (September/October); e252-e256)

  • PMID: 32984532

  • DOI: 10.4158/ACCR-2020-0154


Objective: We report a case of thyrotoxic periodic paralysis (TPP) in a bodybuilder who developed paralysis secondary to thyrotoxicosis factitia after taking a supplement containing thyroid hormone. Interestingly, the patient had no intrinsic thyroid disease. Prompt recognition of thyrotoxicosis is critical to avoid progression of paralysis and subsequent complications.

Methods: We discuss a 27-year-old body builder who presented after a 3-day bodybuilding competition with sudden upper and lower extremity paralysis. He admitted to taking anabolic steroids, a supplement containing an unknown amount of thyroid hormone for 2 weeks, and furosemide 40 mg twice daily with near-complete fluid restriction for 3 days.

Results: Laboratory results showed a thyroid-stimulating hormone (TSH) level of <0.010 μIU/mL (normal, 0.3 to 5.8 μIU/mL), normal total triiodothyronine level, elevated free thyroxine level of 3.6 ng/dL (normal, 0.8 to 1.9 ng/dL), and potassium level of 1.9 mEq/L (normal, 3.7 to 5.2 mEq/L). Thyroid peroxidase antibody, thyroid-stimulating immunoglobulin, and thyroglobulin antibody levels were normal. Thyroid uptake was 1% (normal, 8 to 25%) after administration of I-123 and thyroglobulin level was 9 ng/mL (normal, 1.4 to 29.2 ng/mL). The patient was treated with normal saline infusion, magnesium supplementation and a total of 230 mEq of potassium within 12 hours of hospitalization. Muscle weakness resolved within this time period and potassium level normalized. By the third day of hospitalization free thyroxine level also normalized and TSH improved to 0.1 mIU/L.

Conclusion: TPP is a rare complication of thyrotoxicosis that should be considered in bodybuilders who are presenting with acute muscle weakness.

Sudden Cardiac Death in Anabolic-Androgenic Steroid Users: A Literature Review

Sudden Cardiac Death in Anabolic-Androgenic Steroid Users : A Literature Review / Marco Torrisi, Giuliana Pennisi, Ilenia Russo, Francesco Amico, Massimiliano Esposito, Aldo Liberto, Giuseppe Cocimano, Monica Salerno, Giuseppe Li Rosi, Nunzio Di Nunno, Angelo Montana. - (Medicina 56 (2020) 11 (4 November); p. 1-19)

Background and objectives: Anabolic-androgenic steroids (AASs) are a group of synthetic molecules derived from testosterone and its related precursors. AASs are widely used illicitly by adolescents and athletes, especially by bodybuilders, both for aesthetic uses and as performance enhancers to increase muscle growth and lean body mass. When used illicitly they can damage health and cause disorders affecting several functions. Sudden cardiac death (SCD) is the most common medical cause of death in athletes. SCD in athletes has also been associated with the use of performance-enhancing drugs. This review aimed to focus on deaths related to AAS abuse to investigate the cardiac pathophysiological mechanism that underlies this type of death, which still needs to be fully investigated. Materials and Methods: This review was conducted using PubMed Central and Google Scholar databases, until 21 July 2020, using the following key terms: "((Sudden cardiac death) OR (Sudden death)) AND ((androgenic anabolic steroid) OR (androgenic anabolic steroids) OR (anabolic-androgenic steroids) OR (anabolic-androgenic steroid))". Thirteen articles met the inclusion and exclusion criteria, for a total of 33 reported cases. Results: Of the 33 cases, 31 (93.9%) were males while only 2 (61%) were females. Mean age was 29.79 and, among sportsmen, the most represented sports activity was bodybuilding. In all cases there was a history of AAS abuse or a physical phenotype suggesting AAS use; the total usage period was unspecified in most cases. In 24 cases the results of the toxicological analysis were reported. The most detected AASs were nandrolone, testosterone, and stanozolol. The most frequently reported macroscopic alterations were cardiomegaly and left ventricular hypertrophy, while the histological alterations were foci of fibrosis and necrosis of the myocardial tissue. Conclusions: Four principal mechanisms responsible for SCD have been proposed in AAS abusers: the atherogenic model, the thrombosis model, the model of vasospasm induced by the release of nitric oxide, and the direct myocardial injury model. Hypertrophy, fibrosis, and necrosis represent a substrate for arrhythmias, especially when combined with exercise. Indeed, AAS use has been shown to change physiological cardiac remodeling of athletes to pathophysiological cardiac hypertrophy with an increased risk of life-threatening arrhythmias.

Effects of oral administration of androstenedione on plasma androgens in young women using hormonal contraception

Effects of oral administration of androstenedione on plasma androgens in young women using hormonal contraception / Thomas Bassindale, David A. Cowan, Sian Dale, Andrew J. Hutt, Anthony R. Leeds, Michael J. Wheeler, Andrew T. Kicman. - (Journal of Clinical Endocrinology & Metabolism 89 (2004) 12 (1 December); p. 6030-6038)

Androstenedione as a dietary supplement has been targeted at the sporting community, but there are limited data regarding its effects on plasma androgens in young women. A double-blind, cross-over study was undertaken involving 10 women (20-32 yr) using hormonal contraception. Because contamination of supplements has been reported, an in-house oral formulation was prepared containing purified androstenedione, the control being lactose only. After oral administration of a single dose of androstenedione (100 mg), blood was collected frequently up to 8 h and at 24 h. Maximum plasma androgen concentrations observed between volunteers were well above the upper limit of reference ranges for women, being 121-346 nmol/liter for androstenedione, 14-54 nmol/liter for testosterone (T), 11-32 nmol/liter for 5alpha-dihydrotestosterone, and 23-90 nmol/liter for 3alpha-androstanediol glucuronide. The free androgen index and T concentration changed in a similar manner. The mean change in area under the plasma concentration-time curve (0-24 h), compared with control data were: androstenedione approximately 7-fold, T approximately 16-fold, 5alpha-dihydrotestosterone approximately 9-fold, and 3alpha-androstanediol glucuronide approximately 5-fold; the mean conversion ratio of androstenedione to T was 12.5% (range 7.8-21.6%). Increases in T area under the plasma concentration-time curve were correlated with SHBG concentration (r = 0.80; P = 0.005). Formulation characteristics and SHBG levels appear to be important factors when considering plasma androgen increases after acute androstenedione administration.

Sporcular arasında anabolik androjenik steroid ve efedrin kullanımı =  Anabolic-Androgenic Steroid and Ephedrine Use Among Sportsmen / Erdal Vardar, Cem Kurt, S. Arzu Vardar. - (Bağımlılık Dergisi = Journal of Dependence (2004) 5; p. 20-25)

  • English abstract


Objective: Anabolic-androgenic steroids (AAS) and ephedrine are used to enhance athletic performance or physical appearance among sportsmen. The use of these drugs can produce serious adverse medical and psychiatric effects. The primary purpose of the present study was to determine the rate of AAS and ephedrine containing drug use in sportsmen; and secondarily, to identify the socio-demographic features, dependence and abuse characteristics in AAS and ephedrine users.

Methods: In the city of Edirne, two-hundred forty-two sportsmen at Trakya University Sport Academy and sportsmen attending private gymnasiums were included in the study. Subjects completed a self report questionnaire for socio-demographic features, drug abuse and dependence characteristics. DSM-IV research criteria of drug abuse and dependence were used to identify the characteristics of AAS and ephedrine users over the preceding [year].

Results: The results showed that 27 (11%) of the sportsmen had used AAS and ephedrine within the last 1 [year]. Of the 27 drug users, 6 of them were female and 6 of them were still using drugs at the time of the interview. One third of the users of AAS and drugs containing ephedrine met at least one DSM-IV research criteria for dependence and abuse. AAS and ephedrine use were more prevalent in wrestlers and body builders compared to other sportsmen. Withdrawal was the most frequently reported symptom and this symptom was characterized mainly by the presence of depressive moods. 77% of the drug users reported that they had begun to use these drugs at the behest of their trainers.

Conclusion: AAS and ephedrine containing drugs use was shown to have become widespread among sportsmen in the city of Edirne. The use of these drugs may induce abuse and dependence problems among the sportsmen.

Undeclared furosemide in food supplements

Recent studies claim that dietary supplements could contain pharmaco-active ingredients or undeclared drug substances with a potential health risk. Most often these products are contaminated with anabolic steroids, ephedrine, sibutramine, diuretics and others. The intake of a contaminated dietary supplement could lead to serious health consequences (the pharmacological effect of the substances, side effects, drug interactions and many others) or other negative consequences like failure of a doping test (for professional athletes). We have performed HPLC screening for furosemide. Measurements were performed at 228 nm at a flow rate 0,8 ml/min. The mobile phase was composed of methanol and water in a ratio 80: 20 (v/v). The pH of the mobile phase was 3,3 adjusted with Phosphorous acid. Chromatographic column - Microsorb-MV 100-5 C18 150 × 4.6 mm. We have analysed 30 food supplements in the category”prostate health”. We have found undeclared furosemide in 10% of the samples.
