Anabolic steroid use: patterns of use and detection of doping

Knowledge and Awareness About Anabolic-Androgenic Steroid Use as a Body Shape Enhancer and Its Side Effects Among Adult Gym Participants in Jeddah, Saudi Arabia

BACKGROUND

Anabolic steroids, often referred to as anabolic-androgenic steroids, are steroidal androgens that include testosterone and other naturally occurring androgens, as well as synthetic androgens that are chemically linked to testosterone and have similar actions.

MATERIAL AND METHODS

A cross-sectional study was conducted to evaluate the knowledge and awareness about anabolic-androgenic steroid (AAS) use and its side effects among adult gym participants in Jeddah. A total of 269 adults fulfilling the inclusion criteria were included. The questionnaire covered the demographics, attitudes, and behaviors associated with AAS use and consisted of single-response questions and four multiple-response questions. All statistical methods used were two-tailed with an alpha level of 0.05, considering significance if the p-value was less than or equal to 0.05. The overall awareness score was categorized as "poor" if the students' score was less than 60% of the overall score and "good" if the students' score was 60% or more. Descriptive analysis was done by prescribing frequency distributions and percentages for study variables, including the adult's personal data, reasons for going to the gym, and duration.

RESULTS

This study shows a prevalence of 6.3% of adults' use of AAS, which was higher than in some regions in Saudi Arabia. The largest age group that uses AAS, according to this study, is 26-45 years old. A total of 185 (68.8%) were males, and a total of 185 (68.8%) were university graduates. The most reported reasons for going to the gym included fitness (63.2%), muscle building (52.8%), entertainment (39.4%), and weight loss (37.9%). 94.4% of people think that anabolic steroids are harmful to the body, and 80.3% know that misuse of anabolic steroids may lead to problems with the kidneys and liver. 75.1% of male adults and 76.8% of university graduates had good knowledge and awareness. The internet is the most common source of information.

CONCLUSION

Our study provides clear evidence that there is a high awareness of AAS and its side effects and a high prevalence of its use among male gym participants in Jeddah. The use of AAS is a national problem that the authorities need to act on. There is a strong need for health policy reforms to reduce the rise of AAS use among young adults.

The Uses of Anabolic Androgenic Steroids Among Athletes; Its Positive and Negative Aspects- A Literature Review

The use of anabolic androgenic steroids (AAS) for strength training and muscle building is a widespread practice among athletes and young individuals. Athletes and bodybuilders are using these substances for various purposes, such as enhancing muscle mass, strengthening their bodies, and enhancing their performances. AAS exert a wide range of physiological effects that result in the activation of central signaling, resulting in adverse effects. Moreover, excessive use of AAS which can be categorized as AAS abuse; is linked to biological and psychological pathologies, which can lead to mortality. Complications arising from steroid abuse involve both cellular and physiological complications. Cellular complications arise when activation of signaling proteins like mTOR, Akt, etc. leads to alteration in protein synthesis pathways, cell cycle, oxidative stress, and apoptosis, contributing to damage at the cellular level. Physiological complications are evident with cardiovascular pathologies, including an altered lipid profile, cardiac hypertrophy, hypogonadism after discontinuation of AAS, and modulation of GABA receptors in the brain, all contributed by the androgen receptor signaling. Clinical complications budding from these altered physiological processes lead to clinical effects like testicular dysfunction, acne, gynecomastia, and neuropsychiatric disorders. Despite potential therapeutic benefits, AAS use is prohibited by the World Anti-Doping Agency (WADA) due to concerns over adverse health effects. This review highlights the molecular mechanisms, physiological processes, and clinical complications arising from the excessive use of AAS among athletes.

Anabolic androgenic steroids and cardiomyopathy: an update

Anabolic androgenic steroids (AAS) include endogenously produced androgens like testosterone and their synthetic derivatives. Their influence on multiple metabolic pathways across organ systems results in an extensive side effect profile. From creating an atherogenic and prothrombotic milieu to direct myocardial injury, the effects of AAS on the heart may culminate with patients requiring thorough cardiac evaluation and multi-disciplinary medical management related to cardiomyopathy and heart failure (HF). Supraphysiological doses of AAS have been shown to induce cardiomyopathy via biventricular dysfunction. Advancement in imaging including cardiac magnetic resonance imaging (MRI) and additional diagnostic testing have facilitated the identification of AAS-induced left ventricular dysfunction, but data regarding the impact on right ventricular function remains limited. Emerging studies showed conflicting data regarding the reversibility of AAS-induced cardiomyopathy. There is an unmet need for a systematic long-term outcomes study to empirically evaluate the clinical course of cardiomyopathy and to assess potential targeted therapy as appropriate. In this review, we provide an overview of the epidemiology, pathophysiology and management considerations related to AAS and cardiomyopathy.

The deleterious effects of anabolic androgenic steroid abuse on sexual and reproductive health and comparison of recovery between treated and untreated patients: Single-center prospective randomized study

Anabolic androgenic steroids (AAS) abuse is a global health-related concern, as most of the related studies showed increasing trends and deleterious effects, mostly on sexual and fertility health. Unfortunately, there are no consensuses about the management pathways due to the lack of specific guidelines. We aimed to confirm the deleterious effects of AAS abuse, monitor the spontaneous recovery, and demonstrate the effects of treatment regimens on recovery. We enrolled 520 patients with a confirmed history of AAS intake within 1 year of presentation and evaluated their symptoms, hormones levels, and semen every 3 months until 12 months. All patients were monitored for spontaneous recovery in the first 3 months; if they showed no recovery, they were randomized to undergo either continued observation or commence medications. The most common presentation (84%) was a combination of sexual symptoms while some patients (18%) were infertile. Most patients (90%) reported low levels of luteinizing hormone, follicle-stimulating hormone, and total testosterone. After the 3-month observation, most patients (89%) started treatment, but some (11%) continued observation only. Treated patients showed faster improvement regarding the International Index of Erectile Function (IIEF) values, hormone levels, testicular size and semen parameters compared to non-treated patients (p < 0.005). Among the 94 patients who presented with infertility (18%), 61 had oligospermia and 33 had azoospermia. All received treatment, but only 14 (15%) achieved successful pregnancy at 12 months while all azoospermic's patients continued to have infertility at the end of the follow-up period. These findings demonstrated the significant negative impact of AAS abuse on sexual health and fertility, and the need for medical treatment to have faster recovery from their adverse effect.

Reduced arterial elasticity after anabolic-androgenic steroid use in young adult males and mice

High-doses of anabolic-androgenic steroids (AAS) is efficient for building muscle mass, but pose a risk of cardiovascular side effects. Little is known of the effect of AAS on vasculature, but previous findings suggest unfavorable alterations in vessel walls and vasoreactivity. Here, long-term effect of AAS on vascular function and morphology were examined in male weightlifters, and in a mimicking animal model. Arterial elasticity and morphology were tested with ultrasound, pulse wave velocity (PWV) and carotid intima media thickness (cIMT) in 56 current male AAS users, and 67 non-exposed weightlifting controls (WLC). Female mice were treated with testosterone for 14 days and echocardiography were applied to evaluate vascular function and morphology. Male AAS users had higher PWV (p = 0.044), reduced carotid artery compliance (p = 0.0005), and increased cIMT (p = 0.041) compared to WLC. Similar functional changes were found in the ascending aorta of mice after 7- (p = 0.043) and 14 days (p = 0.001) of testosterone treatment. This animal model can be used to map molecular mechanisms responsible for complications related to AAS misuse. Considering the age-independent stiffening of major arteries and the predictive power of an increase in PWV and cIMT, the long-term users of AAS are at increased risk of severe cardiovascular events.

The Safety of Human Chorionic Gonadotropin Monotherapy Among Men With Previous Exogenous Testosterone Use

Background and objective

Human chorionic gonadotropin (hCG) is homologous to luteinizing hormone (LH) and stimulates endogenous testosterone (T) production. Current American Urological Association (AUA) guidelines recommend hCG for T-deficient men who wish to preserve their fertility. However, there is no data available regarding the long-term efficacy and safety of hCG monotherapy in men with a history of exogenous T use. We hypothesized that transitioning to hCG would be a safe and effective option in this population.

Methodology

We performed a retrospective analysis involving 28 men with previous exogenous T use who were switched to hCG monotherapy and underwent follow-up lab work at least one month later. We evaluated changes in hormones [T, LH, follicle-stimulating hormone (FSH), and estradiol], hematocrit (HCT), glycated hemoglobin (HbA1c), and prostate-specific antigen (PSA).

Results

Among the entire cohort, we found no significant change in mean hormone levels (including T), HbA1c, or PSA. There was a significant (p<0.05) decrease in HCT (45.27 ±4.06 to 44.16 ±3.48%, n=15). No thromboembolic events were reported. Additionally, among men who had their baseline labs completed outside their previous T therapy therapeutic time window prior to starting hCG monotherapy, there was a statistically significant increase in mean T levels (307.36 ±148.74 to 422.11 ±268.15 ng/dL, n=30 and 31, pre- and post-hCG, respectively) and a statistically significant decrease in mean PSA levels (0.91 ±0.35 to 0.69 ±0.23 ng/mL, n=5).

Conclusions

These results suggest that hCG is a safe and effective alternative to traditional T therapy for men with a history of exogenous T use and may lead to an advantageous decrease in HCT. hCG may serve as an alternative form of T therapy with a lower risk for secondary erythrocytosis, and further research is warranted to gain deeper insights into the topic.

Anabolic-Androgenic Steroid Misuse: Mechanisms, Patterns of Misuse, User Typology, and Adverse Effects

Anabolic-androgenic steroids (AAS) encompass a broad group of natural and synthetic androgens. AAS misuse is highly prevalent on a global scale, with the lifetime prevalence of AAS misuse in males being estimated to be around 6%, with 15 to 25% of male gym attendees using it at any one time. AAS are associated with sudden cardiac death, neuropsychiatric manifestations, and infertility. The average AAS user is unlikely to voluntarily declare their usage to a physician, with around 1 in 10 actively engaging in unsafe injection techniques. The aim of this paper is to review the current evidence base on AAS with emphasis on mechanisms of action, adverse effects, and user profiles that are most likely to engage in AAS misuse. This paper also reviews terminologies and uses methods specific to the AAS user community.

Central serous chorioretinopathy: An update on risk factors, pathophysiology and imaging modalities

Central serous chorioretinopathy (CSC) is a common form of vision loss, typically seen in working-age men. The pathophysiology behind CSC still eludes us, however significant advances have been made in understanding this disease over the last decade using information from genetic and cell-based studies and imaging modalities. This review aims to give an overview of the current pathophysiology hypotheses surrounding CSC in addition to future directions in cellular work from human induced pluripotent stem cell derived choroidal endothelial cells from CSC patients. Furthermore, this review will provide the reader with an update on the clinical aspects of CSC including risk factors, diagnostic challenges and findings from multimodal imaging.

Anabolic-androgenic Steroid Use Among Gynecomastia Patients: Prevalence and Relevance to Surgical Management

BACKGROUND

Anabolic-androgenic steroids (AAS) are widely implicated in gynecomastia development. Surgery is the definitive treatment for cases persisting after cessation of AAS use. Currently, the relevance of AAS use to the surgical approach of gynecomastia has not been well explored. This study aims to compare patient characteristics, surgical outcomes, and surgical management of gynecomastia correction in AAS users versus nonusers.

METHODS

A retrospective cohort study was performed with patients who underwent bilateral gynecomastia reduction surgery between January 2005 and August 2015 by a single surgeon at an academic hospital. Demographic data, AAS usage details, operative documentation, and follow-up outcomes were reviewed.

RESULTS

A total of 964 cases were reviewed. Eleven percent (n = 105) of the patients had a history of AAS use. Compared with non-AAS users, AAS users were older at time of gynecomastia onset (15 years vs 13 years, P < 0.001) and surgery (28 years vs 25 years, P < 0.001). The AAS users had higher body mass index (27.3 kg/m vs 25.7 kg/m, P < 0.001) and a greater proportion of patients self-identified as bodybuilders (40.0% vs 22.4%, P = 0.002). Although no difference was found in the excised bilateral mastectomy volume (92.1 cm vs 76.4 cm, P = 0.20), The AAS users had significantly less lipoaspirate fat volume (250 mL vs 300 mL, P = 0.005). No difference was found in total complication rates. However, AAS users had significantly more revision mastectomy surgeries (3.8% vs 1.1%; P = 0.02).

CONCLUSIONS

The unique breast composition of AAS users necessitates a surgical approach with meticulous intraoperative hemostasis and careful glandular excision to minimize recurrence and achieve comparable low complication rates.

Application of online two-dimensional high-performance liquid chromatography as purification procedure to determine the origin of 19-norandrosterone in urine by gas chromatography-combustion-isotope ratio mass spectrometry

19-Norandrosterone (19-NA) is the main metabolite of nandrolone and/or its precursors, which can be found naturally in human urine in trace amount. Gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) confirmation procedure can be used to identify a potential exogenous origin of 19-NA in urine sample. Sample purification for GC-C-IRMS analysis is crucial to the whole confirmation procedure because the concentration of 19-NA in the urine to be tested is very low. Online two-dimensional high-performance liquid chromatography (2D-HPLC) clean-up procedure with high separation capacity is used to isolate and enrich 19-NA as a sample pretreatment process. Linearity, lowest detectable concentration, uncertainty, and selectivity of the method are validated according to the World Anti-doping Agency's (WADA) requirement. Isotope fractionation effect was not observed during the 2D-HPLC purification process. The validated method provides a high efficient and convenient confirmation procedure to determine the origin of 19-NA.

Analytical approaches applied to the analysis of apprehended formulations of anabolic androgenic steroids

Anabolic androgenic steroids (AASs) comprise a class of synthetic androgens resulting from chemical modifications of testosterone, known for their illicit consumption, which can result inextensive side effects. Extraction procedures applied to the analysis of their formulations are still limited to a few methodologies, despite the increasing numbers of confiscations of AASs. In this sense, the aims of this work were to evaluate the extraction of active ingredients from formulations of anabolic agents using solid-liquid or liquid-iquid, ultrasonic bath, ultrasonicprobe, and microwave-assisted extraction. The results indicated that the extraction procedures influenced the detected concentration of AASs, as the use of ultrasonic probe and microwave irradiation increased the overall extraction of anabolic agents compared with solid-liquid, liquid-liquid, and ultrasonic bath. Regarding oxymetholone, for instance, the microwave-assisted extraction and ultrasonic probe extracted, respectively, 37.46 ± 1.36 and 35.69 ± 0.98 mg/tablet, while solid-liquid extracted 29.63 ± 0.40 mg/tablet of the activeingredient. Therefore, alternative methods such as microwave-assisted extraction or theultrasonic probe could be used for the analysis of formulations of AASs assisting with the identification of illicit and toxic components.

Abuse of androgenic anabolic drugs with "Cycling" induces hepatic steatosis in adult male mice

BACKGROUND

The importance of the present study comes from the lack of sufficient information about the reversibility of the potential hepatic histopathological alterations which may result from anabolic androgenic drugs abuse by "Cycling" protocol. So, the aim of this study is to explore the negative effects of Deca-Durabolin abuse in hepatic function and structure during an administration cycle.

METHODS

For our purpose, study was performed on 40 male adult mices. Animals were divided into five groups of 8 animals each treated weekly by Deca-Durabolin (nandrolone decanoate) at 30 g/kg of BW during one month (GI); during two months (GII); during three months (GIII); during three months followed by six weeks of treatment discontinuation (GIV) and Control (C). Plasma assay of liver enzymes (ALT and AST) and cytohistological examination to determine the histopathological damage properties of the liver were performed.

RESULTS

Our results showed that the animals supported very well the administrated substance. Our study showed an increase in plasma levels of liver enzymes (ALT and AST) with the duration of treatment accompanied by important degenerative changes in hepatic tissue with peliosis evolution after two months of treatment. These damages worsen again 6 weeks after stopping treatment and ended by the development of hepatic steatosis with increases hepatic distress.

CONCLUSION

These results ported that the use of AAS with "Cycling" may lead to the development of hepatic steatosis before progressing to more serious pathological liver situations in AAS abusers.

Evolutions in cardiac and gonadal ultra-structure during a "cycle" of androgenic anabolic abuse in adult male mice

BACKGROUND

The importance of the present study comes from the lack of sufficient information about the reversibility of the potential histopathological alterations which may result from anabolic androgenic drugs abuse by "Cycling" protocol. So, the aim of this study is to explore the negative effects of Deca-Durabolin abuse in cardiac and gonadal ultra-structures during an administration cycle.

METHODS

For our purpose, study was performed on 40 male adult mices. Animals were divided into five groups of 8 animals each treated weekly by Deca-Durabolin (nandrolone decanoate) at 30 g/kg of BW during one month (GI); during two months (GII); during three months (GIII); during three months followed by six weeks of treatment discontinuation (GIV) and Control (C). Cytohistological examinations to determine the histopathological damage properties of the heart and tests were performed.

RESULTS

Our results showed that the animals supported very well the administrated substance. Our study showed important degenerative changes in cardiac and gonadal tissues after one months of androgen abuse. These damages increases with the duration of treatment with well marked cell lesions, and worsen again 6 weeks after stopping treatment in cardiac tissue, whereas the gonadal tissue does not recover completely during this period.

CONCLUSION

These results ported that the use of AAS with "Cycling" may lead to irreversibly destroy the heart tissue. Either, "Cycling" does not ensure the complete recovery of fertility in AAS abusers.

Separation of Structurally Similar Anabolic Steroids as Cation Adducts in FAIMS-MS

Novel synthetic anabolic androgenic steroids have been developed not only to dodge current antidoping tests at the professional sports level, but also for consumption by noncompetitive bodybuilders. These novel anabolic steroids are commonly referred to as "designer steroids" and pose a significant risk to users because of the lack of testing for toxicity and safety in animals or humans. Manufacturers of designer steroids dodge regulation by distributing them as nutritional or dietary supplements. Improving the throughput and accuracy of screening tests would help regulators to stay on top of illicit anabolic steroids. High-field asymmetric-waveform ion mobility spectrometry (FAIMS) utilizes an alternating asymmetric electric field to separate ions by their different mobilities at high- and low-fields as they travel through the separation space. When coupled to mass spectrometry (MS), FAIMS enhances the separation of analytes from other interfering compounds with little to no increase in analysis time. Here we investigate the effects of adding various cation species to sample solutions for the separation of structurally similar or isomeric anabolic androgenic steroids. FAIMS-MS spectra for these cation-modified samples show an increased number of compensation field (CF) peaks, some of which are confirmed to be unique for one steroid isomer over another. The CF peaks observed upon addition of cation species correspond to both monomer steroid-cation adduct ions and larger multimer ion complexes. Notably, the number of CF peaks and their CF shifts do not appear to have a straightforward relationship with cation size or electronegativity. Future directions aim at investigating the structures for these analyte-cation adduct ions for building a predictive model for their FAIMS separations.

One-Pot SELEX: Identification of Specific Aptamers against Diverse Steroid Targets in One Selection

Aptamers are well-established biorecognition molecules used in a wide variety of applications for the detection of their respective targets. However, individual SELEX processes typically performed for the identification of aptamers for each target can be quite time-consuming, labor-intensive, and costly. An alternative strategy is proposed herein for the simultaneous identification of different aptamers binding distinct but structurally similar targets in one single selection. This one-pot SELEX approach, using the steroids estradiol, progesterone, and testosterone as model targets, was achieved by combining the benefits of counter-SELEX with the power of next-generation sequencing and bioinformatics analysis. The pools from the last stage of the selection were compared in order to discover sequences with preferential abundance in only one of the pools. This led to the identification of aptamer candidates with potential specificity to a single steroid target. Binding studies demonstrated the high affinity of each selected aptamer for its respective target, and low nanomolar range dissociation constants calculated were similar to those previously reported for steroid-binding aptamers selected using traditional SELEX approaches. Finally, the selected aptamers were exploited in microtiter plate assays, achieving nanomolar limits of detection, while the specificity of these aptamers was also demonstrated. Overall, the one-pot SELEX strategy led to the discovery of aptamers for three different steroid targets in one single selection without compromising their affinity or specificity, demonstrating the power of this approach of aptamer discovery for the simultaneous selection of aptamers against multiple targets.

Supraphysiologic-dose anabolic-androgenic steroid use: A risk factor for dementia?

Supraphysiologic-dose anabolic-androgenic steroid (AAS) use is associated with physiologic, cognitive, and brain abnormalities similar to those found in people at risk for developing Alzheimer's Disease and its related dementias (AD/ADRD), which are associated with high brain β-amyloid (Aβ) and hyperphosphorylated tau (tau-P) protein levels. Supraphysiologic-dose AAS induces androgen abnormalities and excess oxidative stress, which have been linked to increased and decreased expression or activity of proteins that synthesize and eliminate, respectively, Aβ and tau-P. Aβ and tau-P accumulation may begin soon after initiating supraphysiologic-dose AAS use, which typically occurs in the early 20s, and their accumulation may be accelerated by other psychoactive substance use, which is common among non-medical AAS users. Accordingly, the widespread use of supraphysiologic-dose AAS may increase the numbers of people who develop dementia. Early diagnosis and correction of sex-steroid level abnormalities and excess oxidative stress could attenuate risk for developing AD/ADRD in supraphysiologic-dose AAS users, in people with other substance use disorders, and in people with low sex-steroid levels or excess oxidative stress associated with aging.

Tendon Remodeling in Response to Resistance Training, Anabolic Androgenic Steroids and Aging

Exercise training (ET), anabolic androgenic steroids (AAS), and aging are potential factors that affect tendon homeostasis, particularly extracellular matrix (ECM) remodeling. The goal of this review is to aggregate findings regarding the effects of resistance training (RT), AAS, and aging on tendon homeostasis. Data were gathered from our studies regarding the impact of RT, AAS, and aging on the calcaneal tendon (CT) of rats. We demonstrated a series of detrimental effects of AAS and aging on functional and biomechanical parameters, including the volume density of blood vessel cells, adipose tissue cells, tendon calcification, collagen content, the regulation of the major proteins related to the metabolic/development processes of tendons, and ECM remodeling. Conversely, RT seems to mitigate age-related tendon dysfunction. Our results suggest that AAS combined with high-intensity RT exert harmful effects on ECM remodeling, and also instigate molecular and biomechanical adaptations in the CT. Moreover, we provide further information regarding the harmful effects of AAS on tendons at a transcriptional level, and demonstrate the beneficial effects of RT against the age-induced tendon adaptations of rats. Our studies might contribute in terms of clinical approaches in favor of the benefits of ET against tendinopathy conditions, and provide a warning on the harmful effects of the misuse of AAS on tendon development.

Inhibitory Effects of Diclofenac on Steroid Glucuronidation In Vivo Do Not Affect Hair-Based Doping Tests for Stanozolol

In vitro studies show that diclofenac inhibits enzymatic steroid glucuronidation. This study was designed to investigate the influence of diclofenac on the excretion of stanozolol and 3′-hydroxystanozolol via analyses in hair, blood and urine in vivo in a rat study. Brown Norway rats were administered with stanozolol (weeks 1–3) and diclofenac (weeks 1–6). Weekly assessment of steroid levels in hair was complemented with spot urine and serum tests. Levels of both stanozolol and 3′-hydroxystanozolol steadily increased in hair during stanozolol treatment and decreased post-treatment, but remained readily detectable for 6 weeks. In contrast, compared to control rats, diclofenac significantly reduced urinary excretion of 3′-hydroxystanozolol which was undetectable in most samples. This is the first report of diclofenac altering steroid metabolism in vivo, detrimentally affecting detection in urine, but not in hair, which holds considerable advantages over urinalysis for anti-doping tests.

Cardiac hypertrophy and IGF-1 response to testosterone propionate treatment in trained male rats

Objective

Several studies have suggested that testosterone exerts a growth-promoting effect in the heart. Limited data are available regarding interactions between possible endocrine/paracrine effects in response to exercise training. Therefore, we examined supraphysiological testosterone-induced heart hypertrophy and cardiac insulin-like growth factor (IGF)-1 content in sedentary and exercise-trained rats.

Design

Male Wistar rats (n=33) were randomly allocated to groups with a 6-week endurance training with or without testosterone, and sedentary animals with or without testosterone. The hormone (20 mg/250 g body weight was administrated once a week for six weeks. After six weeks the animals were anesthetized, euthanized and the heart was excised and weighed. The left ventricle was separated for biochemical analyses.

Results

Testosterone-treated animals showed significantly higher cardiac IGF-1 content compared to untreated control and trained groups (p=0.01). The administration of supraphysiological testosterone significantly increased the heart weight to body weight ratio (HW/BW, p<0.01). A significant positive correlation was seen between IGF-1 levels and the HW/BW ratio (p=0.002; r=0.50) and between serum total testosterone levels and HW/BW (p=0.000; r=0.79).

Conclusions

The results demonstrate that increased cardiac IGF-1 content in response to higher serum testosterone might be responsible for heart hypertrophy observed in both sedentary and endurance-trained animals.

Use of doping agents and symptoms of eating disorders among male and female patients in drug addiction treatment

Aims

This study investigates the prevalence of use of doping agents and symptoms of eating disorders among patients in drug addiction treatment. The aim is also to look for characteristics of the groups reporting the use of doping agents or symptoms of eating disorders.

Design

A survey including questions on exercise, the use of doping agents and Eating Disorder Inventory-2 was administered in a Norwegian drug addiction facility. The study included 109 patients in residential drug treatment, 30 females and 79 males (ranging from 17 to 50 years old).

Results

–Symptoms of eating disorders were reported by 33 percent of the females and 7.6 percent of the males. Previous use of doping agents (anabolic-androgenic steroids in particular) was reported by 40.5 percent of the men and 20 percent of the women. The results are discussed in light of the theory on emotion regulation, gender and cultural expectations, drug treatment as a liminal phase and similarities to drug addiction.

Conclusions

The symptoms of eating disorders and the use of doping agents are prevalent in this sample of male and female drug addicts in treatment. Drug treatment facilities should be aware of this and take the appropriate actions regarding attention, screening and treatment.

Doping Status of DHEA Treatment for Female Athletes with Adrenal Insufficiency

OBJECTIVE

To review the doping status of dehydroepiandrosterone (DHEA) for female athletes with adrenal insufficiency within the framework of Therapeutic Use Exemption (TUE) applications for this proandrogen, which is included on the World Anti-Doping Agency (WADA)'s Prohibited List.

DATA SOURCES AND MAIN RESULTS

Current knowledge of adrenal pathophysiology with a focus on the physiological role and pharmacological effects of DHEA in female athletes including placebo-controlled clinical trials of DHEA and consensus clinical practice and prescribing guidelines.

CONCLUSIONS

Because there is no convincing clinical evidence to support the use of DHEA replacement therapy in women with adrenal failure, a TUE for DHEA is not justified by definite health benefit for either secondary or primary adrenal failure. This is consistent with the 2014 update of the US Endocrine Society guidelines, meta-analyses of DHEA treatment in women with or without adrenal failure, current WADA TUE guidance document for adrenal insufficiency and recent case law of WADA's Court of Arbitration for Sport.

Determination of pholcodine in syrups and human plasma using the chemiluminescence system of tris(1,10 phenanthroline)ruthenium(II) and acidic Ce(IV)

Pholcodine is an opiate derivative drug which is widely used in pediatric medicine. In this study, a chemiluminescence (CL) method is described that determines pholcodine in human plasma and syrup samples. This method is based on the fact that pholcodine can greatly enhance the weak CL emission of reaction between tris(1,10 phenanthroline)ruthenium(II), Ru(phen)₃²⁺ , and acidic Ce(IV). The CL mechanism is described in detail using UV-vis light, fluorescence and CL spectra. Effects of chemical variables were investigated and under optimum conditions, CL intensity was proportional to the pholcodine concentration over the range 4.0 × 10^-8 to 8.0 × 10^-6  mol  L^-1 . The limit of detection (LOD) (S/N = 3) was 2.5 × 10^-8  mol  L^-1 . Percent of relative standard deviations (%RSD) for 3.0 × 10^-7 and 3.0 × 10^-6  mol  L^-1 of pholcodine was 2.9 and 4.0%, respectively. Effects of common ingredients were investigated and the method was applied successfully to the determination of pholcodine in syrup samples and human plasma.

The misuse of Cyproheptadine: a non-communicable disease risk behaviour in Kinshasa population, Democratic Republic of Congo

Background

Obesity is one of the main risk factors of non-communicable diseases (NCDs) worldwide, especially in sub-Saharan Africa. The use of Cyproheptadine increases body weight and the risk of becoming obese. The aim of this study is to determine the prevalence of Cyproheptadine misuse in the Kinshasa population and to describe its characteristics.

Methods

A cross-sectional study was conducted in two town sectors of Kinshasa, Democratic Republic of Congo (DRC), over a 4 month period (May 2011 to August 2011). Data from 499 participants, aged between 13 and 55 years were collected and analyzed. Mean and standard deviation were used for quantitative variables and frequency and percentage for categorical variables. In order to determine the relationship between socio-demographic status and Cyproheptadine use the Chi-square test was conducted. Student’s t-test was used to compare means age of Cyproheptadine users and non-users. Logistic regression was used to determine predictors of Cyproheptadine use. A p-value of <0.05 was considered statistically significant.

Results

Overall, 499 participants were enrolled (352 females, 147 males, mean age ± standard deviation 24.9 ± 9.7 years) in the study. The majority of the study participants (72.9 %) had used Cyproheptadine as an appetite stimulant. Females were 11 times more likely to use Cryproheptadine (OR = 11.9; 95 % CI: 7.1–20.1) than males. People aged between 36 and 55 were three times less likely to use Cryproheptadine (OR = 0.3; 95 % CI: 0.2–0.8) compared to teenagers. More than half of the participants (69.0 %) declared to take daily Cyproheptadine. Half of the study participants (50.0 %) used Cyproheptadine for more than a year and also declared to combine it with Dexamethasone (87.6 %).

Conclusion

This study shows that the Kinshasa population is significantly misusing Cyproheptadine and is highly exposed to its risk, including obesity.

Anabolic steroids abuse and male infertility

For several decades, testosterone and its synthetic derivatives have been used with anabolic and androgenic purposes. These substances were first restricted to professional bodybuilders, but become more and more popular among recreational athletes. Up to date, 3,000,000 anabolic-androgenic steroids (AAS) users have been reported in the United States with an increasing prevalence, making AAS consumption a major public health growing concern. Infertility is defined by the WHO as the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse and a male factor is present in up to 50 % of all infertile couples. Several conditions may be related to male infertility.

Substance abuse, including AAS, is commonly associated to transient or persistent impairment on male reproductive function, through different pathways. Herein, a brief overview on AAS is offered. Steroids biochemistry, patterns of use, physiological and clinical issues are enlightened. A further review about fertility outcomes among male AAS abusers is also presented, including the classic reports on transient anabolic steroid-induced hypogonadism (ASIH), and the more recent experimental reports on structural and genetic sperm damage.

Anabolic steroid-induced hypogonadism: diagnosis and treatment

OBJECTIVE

To develop an understanding of hypogonadal men with a history of anabolic-androgenic steroid (AAS) use and to outline recommendations for management.

DESIGN

Review of published literature and expert opinions. Intended as a meta-analysis, but no quality studies met the inclusion criteria.

SETTING

Not applicable.

PATIENT(S)

Men seeking treatment for symptomatic hypogonadism who have used nonprescribed AAS.

INTERVENTION(S)

History and physical examination followed by medical intervention if necessary.

MAIN OUTCOME MEASURES(S)

Serum testosterone and gonadotropin levels, symptoms, and fertility restoration.

RESULT(S)

Symptomatic hypogonadism is a potential consequence of AAS use and may depend on dose, duration, and type of AAS used. Complete endocrine and metabolic assessment should be conducted. Management strategies for anabolic steroid-associated hypogonadism (ASIH) include judicious use of testosterone replacement therapy, hCG, and selective estrogen receptor modulators.

CONCLUSION(S)

Although complications of AAS use are variable and patient specific, they can be successfully managed. Treatment of ASIH depends on the type and duration of AAS use. Specific details regarding a patient's AAS cycle are important in medical management.

Anabolic steroids affect human periodontal health and microbiota

OBJECTIVES

This study aims to evaluate periodontal microbiological differences between systemically healthy nonsmoker males taking anabolic androgenic steroids (AASs) and non-AAS users and to find associations between disease severity and AAS use.

METHODS

Ninety-two men practicing bodybuilding were included in the study. They were divided into AAS users and a matched control nonuser group and subgrouped based on their most severe periodontal condition. Pooled subgingival samples from each individual were cultured to evaluate specific periodontopathogen infection.

RESULTS

AAS users had significantly higher prevalence of severe periodontitis. AAS users had greater gingival inflammation and clinical attachment loss of ≥ 3 mm than nonusers (odds ratio (OR) = 2.4; p = 0.09; 95 % confidence interval (CI) 0.8-6.4). AAS users were 4.9 times more likely to be infected with Prevotella intermedia than AAS nonusers (OR = 4.9; p = 0.003; 95 % CI 1.6-14.7). The OR of presenting subgingival Aggregatibacter actinomycetemcomitans was 8.2 times higher in AAS users (OR = 8.2; p = 0.03; 95 % CI 0.9-70.8). AAS users were 5.6 times more likely to present subgingival Candida spp. than nonusers (OR = 5.6; p = 0.02; 95 % CI 1.1-27.1). AAS users were 14.8 times more likely to present subgingival Candida parapsilosis than nonusers (OR = 14.8; p < 0.0001; 95 % CI 3.1-69.2). The likelihood of AAS users presenting subgingival Candida tropicalis was 4.3 times higher than nonusers (OR = 4.3; p = 0.03; 95 % CI 1.1-16.9). A. actinomycetemcomitans was mostly isolated in individuals with severe periodontitis and was associated with subgingival Porphyromonas gingivalis, P. intermedia, and Candida spp.

CONCLUSIONS

AAS use may increase the risk for severe periodontitis and may cause a subgingival selection of certain Candida species. Specific periodontopathogens, such as Candida dubliniensis and Candida albicans, seem to be negatively affected by AAS use. The higher risk for disease progression in AAS users may be explained by the significantly higher proportions of A. actinomycetemcomitans, P. gingivalis, P. intermedia, and Candida species as compared to controls.

CLINICAL SIGNIFICANCE

Data on the influence of AAS on subgingival periodontopathogens and disease progression are scarce. Higher proportions of specific periodontopathogens are plausible in AAS users. AAS users had a higher prevalence of severe periodontitis, gingival inflammation, and clinical attachment loss. Men taking AAS are at greater risk of periodontitis and specific periodontopathogen infection.

Effect of androgenic-anabolic steroids and heavy strength training on patellar tendon morphological and mechanical properties

Combined androgenic-anabolic steroids (AAS) and overloading affects tendon collagen metabolism and ultrastructure and is often associated with a higher risk of injury. The aim of this prospective study was to investigate whether such effects would be reflected in the patellar tendon properties of individuals with a history of long-term resistance training and AAS abuse (RTS group), compared with trained (RT) and untrained (CTRL) nonsteroids users. Tendon cross-sectional area (CSA), stiffness, Young's modulus, and toe limit strain were measured in vivo, from synchronized ultrasonography and dynamometry data. The patellar tendon of RT and RTS subjects was much stiffer and larger than in the CTRL group. However, stiffness and modulus were higher in the RTS group (26%, P < 0.05 and 30%, P < 0.01, respectively) than in the RT group. Conversely, tendon CSA was 15% (P < 0.05) larger in the RT group than in RTS, although differences disappeared when this variable was normalized to quadriceps maximal isometric torque. Yet maximal tendon stress was higher in RTS than in RT (15%, P < 0.05), without any statistical difference in maximal strain and toe limit strain between groups. The present lack of difference in toe limit strain does not substantiate the hypothesis of changes in collagen crimp pattern associated with AAS abuse. However, these findings indicate that tendon adaptations from years of heavy resistance training are different in AAS users, suggesting differences in collagen remodeling. Some of these adaptations (e.g., higher stress) could be linked to a higher risk of tendon injury.

National Athletic Trainers' Association position statement: anabolic-androgenic steroids

OBJECTIVE

This manuscript summarizes the best available scholarly evidence related to anabolic-androgenic steroids (AAS) as a reference for health care professionals, including athletic trainers, educators, and interested others.

BACKGROUND

Health care professionals associated with sports or exercise should understand and be prepared to educate others about AAS. These synthetic, testosterone-based derivatives are widely abused by athletes and nonathletes to gain athletic performance advantages, develop their physiques, and improve their body image. Although AAS can be ergogenic, their abuse may lead to numerous negative health effects.

RECOMMENDATIONS

Abusers of AAS often rely on questionable information sources. Sports medicine professionals can therefore serve an important role by providing accurate, reliable information. The recommendations provide health care professionals with a current and accurate synopsis of the AAS-related research.

Determination of stanozolol and 3'-hydroxystanozolol in rat hair, urine and serum using liquid chromatography tandem mass spectrometry

Background

Anabolic androgenic steroids, such as stanozolol, are typically misused by athletes during preparation for competition. Out-of-competition testing presents a unique challenge in the current anti-doping detection system owing to logistic reasons. Analysing hair for the presence of a prohibited drug offers a feasible solution for covering the wider window in out-of-competition testing. To assist in vivo studies aiming to establish a relationship between drug levels detected in hair, urine and blood, sensitive methods for the determination of stanozolol and its major metabolite 3^′-hydroxystanozolol were developed in pigmented hair, urine and serum, using brown Norway rats as a model system and liquid chromatography tandem mass spectrometry (LC-MS/MS).

Results

For method development, spiked drug free rat hair, blood and urine samples were used. The newly developed method was then applied to hair, urine and serum samples from five brown Norway rats after treatment (intraperitoneal) with stanozolol for six consecutive days at 5.0 mg/kg/day. The assay for each matrix was linear within the quantification range with determination coefficient (r²) values above 0.995. The respective assay was capable of detecting 0.125 pg/mg stanozolol and 0.25 pg/mg 3^′-hydroxystanozolol with 50 mg hair; 0.063 ng/mL stanozolol and 0.125 ng/mL 3^′-hydroxystanozolol with 100 μL of urine or serum. The accuracy, precision and extraction recoveries of the assays were satisfactory for the detection of both compounds in all three matrices. The average concentrations of stanozolol and 3^′-hydroxystanozolol, were as follows: hair = 70.18 ± 22.32 pg/mg and 13.01 ± 3.43 pg/mg; urine = 4.34 ± 6.54 ng/mL and 9.39 ± 7.42 ng/mL; serum = 7.75 ± 3.58 ng/mL and 7.16 ± 1.97 ng/mL, respectively.

Conclusions

The developed methods are sensitive, specific and reproducible for the determination of stanozolol and 3^′-hydroxystanozolol in rat hair, urine and serum. These methods can be used for in vivo studies further investigating stanozolol metabolism, but also could be extended for doping testing. Owing to the complementary nature of these tests, with urine and serum giving information on recent drug use and hair providing retrospective information on habitual use, it is suggested that blood or urine tests could accompany hair analysis and thus avoid false doping results.

Impact of the emergence of designer drugs upon sports doping testing

Historically, dope-testing methods have been developed to target specific and known threats to the integrity of sport. Traditionally, the source of new analytical targets for which testing was required were derived almost exclusively from the pharmaceutical industry. More recently, the emergence of designer drugs, such as tetrahydrogestrinone that are specifically intended to evade detection, or novel chemicals intended to circumvent laws controlling the sale and distribution of recreational drugs, such as anabolic steroids, stimulants and cannabinoids, have become a significant issue. In this review, we shall consider the emergence of designer drugs and the response of dope-testing laboratories to these new threats, in particular developments in analytical methods, instrumentation and research intended to detect their abuse, and we consider the likely future impact of these approaches.

High-dose testosterone propionate treatment reverses the effects of endurance training on myocardial antioxidant defenses in adolescent male rats

This study was aimed at evaluation of changes in activities of selected antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase) and contents of key nonenzymatic antioxidants (glutathione, protein thiol groups, and α- and γ-tocopherols) in the left heart ventricle of young male Wistar rats subjected to endurance training (treadmill running, 1 h daily, 5 days a week, for 6 weeks) or/and testosterone propionate treatment (8 or 80 mg/kg body weight, intramuscularly, once a week, for 6 weeks) during adolescence. The training alone increased the activities of key antioxidant enzymes, but lowered the pool of nonenzymatic antioxidants and enhanced myocardial oxidative stress as evidenced by elevation of the lipid peroxidation biomarker malondialdehyde. The lower-dose testosterone treatment showed mixed effects on the individual components of the antioxidant defense system, but markedly enhanced lipid peroxidation. The higher-dose testosterone treatment decreased the activities of the antioxidant enzymes, lowered the contents of the nonenzymatic antioxidants, except for that of γ-tocopherol, reversed the effect of endurance training on the antioxidant enzymes activities, and enhanced lipid peroxidation more than the lower-dose treatment. These data demonstrate the potential risk to cardiac health from exogenous androgen use, either alone or in combination with endurance training, in adolescents.

Risk factors for illicit anabolic-androgenic steroid use in male weightlifters: a cross-sectional cohort study

BACKGROUND

Illicit anabolic-androgenic steroid (AAS) abuse, though an important public health problem, remains inadequately studied. Almost all AAS abusers are male and lift weights, but the risk factors for AAS use among male weightlifters remain poorly understood.

METHODS

We recruited 233 experienced male weightlifters, of whom 102 (44%) reported lifetime AAS use, and assessed their childhood and adolescent attributes retrospectively, using structured clinical interviews and computerized questionnaires. This cross-sectional cohort approach-a design that we have formally presented in the recent methodological literature-utilizes a study cohort, not selected for outcomes of interest, and assesses exposures and outcomes retrospectively. We hypothesized that conduct disorder and body-image concerns would be major risk factors for subsequent AAS use among male weightlifters.

RESULTS

Within our study population, many attributes showed little association with AAS use, but conduct disorder and body-image concerns showed strong associations. For individuals with prior conduct disorder versus those without, the hazard ratio (95% confidence interval) for subsequent AAS use was 2.2 (1.5, 3.4). For individuals in the middle versus lowest tertile of scores on a retrospective adolescent muscle-dysmorphia scale, the hazard ratio was 1.5 (.84, 2.6); for the highest versus lowest tertile, the hazard ratio was 3.3 (2.0, 5.3); and for the linear trend of hazard ratios, p < .001.

CONCLUSIONS

Conduct disorder and body-image concerns represent important risk factors for AAS use among male weightlifters. Thus, assessment of these attributes may help to identify individuals most likely to require interventions to discourage this form of substance abuse.

A randomized pilot study of monthly cycled testosterone replacement or continuous testosterone replacement versus placebo in older men

CONTEXT

Cycling androgens has been reported by athletes to improve physical performance by enhancing muscle mass and strength, a paradigm that has not been studied, and may have clinical value in older men being treated with testosterone.

OBJECTIVE

We investigated the efficacy of a monthly cycled testosterone regimen that uses half the testosterone dose as the current standard of care continuous therapy on body composition and muscle strength in older men.

DESIGN, SETTING, AND PATIENTS

Twenty-four community-dwelling older men 70 ± 2 yr of age with total testosterone levels below 500 ng/dl were randomized at the Institute for Translational Sciences-Clinical Research Center into a 5-month double-blind placebo-controlled trial.

INTERVENTION

Subjects were dosed weekly for 5 months, receiving continuous testosterone (TE, n = 8; 100 mg testosterone enanthate, im injection), monthly cycled testosterone (MO, n = 8; alternating months of testosterone and placebo), or placebo (PL, n = 8).

MAIN OUTCOME MEASURES

Main outcomes included body composition by dual-energy x-ray absorptiometry and upper and lower body muscle strength. Secondary outcomes included body weight, serum hormones, and mixed-muscle protein fractional synthesis rate (FSR).

RESULTS

Total lean body mass was increased and percent fat was reduced after 5 months in TE and MO (P < 0.05). Upper body muscle strength increased in TE, and lower body muscle strength increased in TE and MO (P < 0.05). FSR increased in TE and MO (P < 0.05) but not in PL.

CONCLUSIONS

Cycled testosterone improved body composition and increased muscle strength compared with placebo and increased FSR similarly to continuous testosterone.

Anabolic steroids and male infertility: a comprehensive review

What's known on the subject? and What does the study add? The negative impact of AAS abuse on male fertility is well known by urologists. The secondary hypogonadotropic hypogonadism is often highlighted when AAS and fertility are being discussed. On the other hand, the patterns of use, mechanisms of action and direct effects over the testicle are usually overseen. The present study reviews the vast formal and "underground" culture of AAS, as well as their overall implications. Specific considerations about their impact on the male reproductive system are made, with special attention to the recent data on direct damage to the testicle. To our knowledge this kind of overview is absolutely unique, offering a distinguished set of information to the day-by-day urologists. For several decades, testosterone and its synthetic derivatives have been used with anabolic and androgenic purposes. Initially, these substances were restricted to professional bodybuilders, becoming gradually more popular among recreational power athletes. Currently, as many as 3 million anabolic-androgenic steroids (AAS) users have been reported in the United States, and considering its increasing prevalence, it has become an issue of major concern. Infertility is defined as the failure to achieve a successful pregnancy after 12 months or more of regular unprotected intercourse, with male factor being present in up to 50% of all infertile couples. Several conditions may be related to male infertility. Substance abuse, including AAS, is commonly associated to transient or persistent impairment on male reproductive function, through different pathways. Herein, a brief overview on AAS, specially oriented to urologists, is offered. Steroids biochemistry, patterns of use, physiological and clinical issues are enlightened. A further review about fertility outcomes among male AAS abusers is also presented, including the classic reports on transient axial inhibition, and the more recent experimental reports on structural and genetic sperm damage.

Palatal Tissue Enlargement After Subepithelial Connective Tissue Graft Harvest Associated With Anabolic Steroid Abuse

INTRODUCTION

Healing complications associated with androgenic anabolic steroid (AAS) abuse have received minimal attention in the periodontal literature. This case report describes an adverse healing event after palatal subepithelial connective tissue graft (SECTG) harvest associated with AAS abuse.

CASE PRESENTATION

A 35-year-old white male was treated with an SECTG procedure to address gingival recession on the facial aspect of teeth #24 and #25. Donor tissue was harvested from the left hard palate via a single incision technique. The procedure was completed without complication. One week postoperatively, the patient presented with a large asymptomatic overgrowth of tissue from the palatal harvest site. Over the following 5 weeks of continued observation, the lesion demonstrated progressive, spontaneous resolution. Investigation of possible etiology revealed the subject was a recreational bodybuilder with admitted AAS abuse.

CONCLUSIONS

Post-surgical healing can be influenced by AAS abuse. Alterations in connective tissue metabolism and fibroblast activity are known sequelae of AAS abuse; however, patients may be reluctant to admit to steroid abuse during the presurgical interview. Surgeons should suspect the possibility of AAS abuse when postoperative complications present in a patient of muscular body type.

Human growth hormone abuse in male weightlifters

In a study of performance-enhancing substance use among 231 experienced young male weightlifters, we found that 27 (12%) reported illicit use of human growth hormone (HGH) or its bioactive derivative, insulin-like growth factor-1. All of these 27 men also reported use of anabolic-androgenic steroids (AAS) and 22 (81%) met criteria for current or past AAS dependence. Fifteen (56%) also reported current or past dependence on opioids, cocaine, and/or ecstasy. These findings suggest that among young male weightlifters, illicit HGH use has become a common form of substance abuse, frequently associated with both AAS dependence and classical substance dependence. 

Chronic anabolic androgenic steroid exposure alters corticotropin releasing factor expression and anxiety-like behaviors in the female mouse

In the past several decades, the therapeutic use of anabolic androgenic steroids (AAS) has been overshadowed by illicit use of these drugs by elite athletes and a growing number of adolescents to enhance performance and body image. As with adults, AAS use by adolescents is associated with a range of behavioral effects, including increased anxiety and altered responses to stress. It has been suggested that adolescents, especially adolescent females, may be particularly susceptible to the effects of these steroids, but few experiments in animal models have been performed to test this assertion. Here we show that chronic exposure of adolescent female mice to a mixture of three commonly abused AAS (testosterone cypionate, nandrolone decanoate and methandrostenolone; 7.5 mg/kg/day for 5 days) significantly enhanced anxiety-like behavior as assessed by the acoustic startle response (ASR), but did not augment the fear-potentiated startle response (FPS) or alter sensorimotor gating as assessed by prepulse inhibition of the acoustic startle response (PPI). AAS treatment also significantly increased the levels of corticotropin releasing factor (CRF) mRNA and somal-associated CRF immunoreactivity in the central nucleus of the amygdala (CeA), as well as neuropil-associated immunoreactivity in the dorsal aspect of the anterolateral division of the bed nucleus of the stria terminalis (dBnST). AAS treatment did not alter CRF receptor 1 or 2 mRNA in either the CeA or the dBnST; CRF immunoreactivity in the ventral BnST, the paraventricular nucleus (PVN) or the median eminence (ME); or peripheral levels of corticosterone. These results suggest that chronic AAS treatment of adolescent female mice may enhance generalized anxiety, but not sensorimotor gating or learned fear, via a mechanism that involves increased CRF-mediated signaling from CeA neurons projecting to the dBnST.

Counterfeiting in performance- and image-enhancing drugs

The current drastic escalation in obesity may be contributing to the exponential rise in drugs used for image enhancement. Drugs such as anabolic-androgenic steroids (AAS) are perceived as a viable method of achieving a perfect physique. They are also the most widely abused drugs in sport. The Internet has encouraged the abuse of expensive drugs, particularly human growth hormone (hGH), resulting in increased importation for personal use. The substantial increase in this market has opened up avenues for counterfeiting, estimated as a multi-million pound business. The acute adverse effects from contaminated vials may result in a variety of pathologies including communicable diseases. In 2007, in the UK, a series of intramuscular abscesses, requiring surgical treatment, led us to study samples obtained from the underground market. The analysis of 38 parenteral samples and 19 oral samples of tablets was performed by a World Anti-Doping Agency (WADA) accredited laboratory, in an attempt to establish the extent of available counterfeit products. Fifty-three per cent (20) of the injectable AAS esters and 21% (4) of the oral tablets were counterfeit. Culture and sensitivity revealed the presence of skin commensal organisms, which may have contributed to the development of the abscesses. Users of AAS and hGH for sport, including bodybuilding, are currently risking their health because of counterfeit and poorly controlled products.

Effects of co-administration of clenbuterol and testosterone propionate on skeletal muscle in paraplegic mice

Spinal cord injury (SCI) is generally associated with a rapid and significant decrease in muscle mass and corresponding changes in skeletal muscle properties. Although beta(2)-adrenergic and androgen receptor agonists are anabolic substances clearly shown to prevent or reverse muscle wasting in some pathological conditions, their effects in SCI patients remain largely unknown. Here we studied the effects of clenbuterol and testosterone propionate administered separately or in combination on skeletal muscle properties and adipose tissue in adult CD1 mice spinal-cord-transected (Tx) at the low-thoracic level (i.e., induced complete paraplegia). Administered shortly post-Tx, these substances were found to differentially reduce loss in body weight, muscle mass, and muscle fiber cross-sectional area (CSA) values. Although all three treatments induced significant effects, testosterone-treated animals were generally less protected against Tx-related changes. However, none of the treatments prevented fat tissue loss or muscle fiber type conversion and functional loss generally found in Tx animals. These results provide evidence suggesting that clenbuterol alone or combined with testosterone may constitute better clinically-relevant treatments than testosterone alone to decrease muscle atrophy (mass and fiber CSA) in SCI subjects.

Sports doping in the adolescent: the Faustian conundrum of Hors de Combat

The drive toward success in sports and the need for a cosmetically acceptable appearance have driven many adolescents to take a wide variety of so-called doping substances. The consumption of these chemicals in the hope and hype of improved sports performance, fueled by the easing of government restrictions on their proof of safety and efficacy, has resulted in an explosion of so-called ergogenic products available to our youth. Agents that have been used include anabolic steroids, anabolic-like agents, designer steroids, creatine, protein and amino acid supplements, minerals, antioxidants, stimulants, blood doping, erythropoietin, beta-blockers, and others. The use of these agents has considerable potential to cause physical and psychological damage. Use and misuse of drugs in this sports doping process should be discouraged. This discussion reviews some of the agents that are currently being used. Clinicians providing sports medicine care to youth, whether through anticipatory guidance or direct sports medicine management, should educate their young patients about the hype and hyperbole of these products that may keep them out instead of in the game at considerable financial cost to the unwary consumer.

Potentially harmful advantage to athletes: a putative connection between UGT2B17 gene deletion polymorphism and renal disorders with prolonged use of anabolic androgenic steroids

Background and objective

With prolonged use of anabolic androgenic steroids (AAS), occasional incidents of renal disorders have been observed. Independently, it has also been established that there are considerable inter-individual and inter-ethnic differences, in particular with reference to the uridine diphosphate-glucuronosyltransferase 2B17 (UGT2B17) gene, in metabolising these compounds. This report postulates the association of deletion polymorphism in the UGT2B17 gene with the occurrence of renal disorders on chronic exposure to AAS.

Presentation of the hypothesis

The major deactivation and elimination pathway of AASs is through glucuronide conjugation, chiefly catalyzed by the UGT2B17 enzyme, followed by excretion in urine. Excretion of steroids is affected in individuals with a deletion mutation in the UGT2B17 gene. We hypothesize that UGT2B17 deficient individuals are more vulnerable to developing renal disorders with prolonged use of AAS owing to increases in body mass index and possible direct toxic effects of steroids on the kidneys. Elevated serum levels of biologically active steroids due to inadequate elimination can lead to prolonged muscle build up. An increase in body mass index may cause renal injuries due to sustained elevated glomerular pressure and flow rate.

Testing the hypothesis

In the absence of controlled clinical trials in humans, observational studies can be carried out. Real time PCR with allelic discrimination should be employed to examine the prevalence of different UGT2B17 genotypes in patients with impaired renal function and AAS abuse. In individuals with the UGT2B17 deletion polymorphism, blood tests, biofluid analyses, urinalysis, and hair analyses following the administration of an anabolic steroid can be used to determine the fate of the substance once in the body.

Implications of the hypothesis

If the hypothesis is upheld, anabolic steroid users with a deletion mutation in the UGT2B17 gene may be exposed to an increased risk of developing renal disorders. In the current detecting - sanctioning anti-doping system, athletes motivated by the potential to evade detection owing to their unique genetic make-up could subject themselves to a serious health consequence. More research on AAS metabolism in the presence of UGT2B17 gene deletion is required. Benefit - harm evaluations in therapeutic use of anabolic steroids should also consider this potential link between UGT2B17 gene deletion polymorphism and renal disorders.
