Prevalence of anabolic steroid users seeking support from physicians: a systematic review and meta-analysis

OBJECTIVES

To estimate the overall prevalence of androgenic-anabolic steroids (AAS) users seeking support from physicians. Secondary objectives are to compare this prevalence in different locations and among subpopulations of AAS users, and to discuss some of the factors that could have influenced the engagement of AAS users with physicians.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

MEDLINE, PsycINFO, Web of Science and SciELO were searched in January 2022.

ELIGIBILITY CRITERIA

Quantitative and qualitative studies reporting the number of AAS users who sought support from physicians, with no restrictions of language or time of publication.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted data and assessed the quality of studies, including publication bias. A random-effects meta-analysis was performed to estimate the overall prevalence of AAS users seeking support from physicians, followed by pooled prevalence rates by studies' location and the subpopulation of AAS users.

RESULTS

We identified 36 studies published between 1988 and 2021, involving 10 101 AAS users. The estimated overall prevalence of AAS users seeking support from physicians is 37.12% (95% CI 29.71% to 44.52%). Higher prevalence rates were observed in studies from Australia (67.27%; 95% CI 42.29% to 87.25%) and among clients of the needle and syringe exchange programme (54.13%; 95% CI 36.41% to 71.84%). The lowest prevalence was observed among adolescent AAS users (17.27%; 95% CI 4.80% to 29.74%).

CONCLUSION

Our findings suggest that about one-third of AAS users seek support from physicians, with remarkable differences between locations and subpopulations of AAS users. Further studies should investigate the factors influencing the engagement of AAS users with physicians.

Sternoclavicular Joint Septic Arthritis and Anterior Mediastinal Mass in a Young Athlete: Possible Immune-modulatory Effect of Growth Hormone

Septic arthritis of sternoclavicular joint (SCJ) is a rare disease, however, not uncommon in patients who abuse intravenous drugs. It can present with a wide range of manifestations that can pose diagnostic challenges, which can result in a delay in diagnosis and treatment. Over the last few decades, there is a surge in the use of nonprescription recombinant human growth hormone (rhGH) by the young healthy population and athletes for its purported ergogenic effects. Furthermore, we lack quantitative information about the adverse effects of the chronic use of rhGH in a healthy population due to the scarcity of epidemiological data. We are reporting a case of a young male athlete who was chronically using the subcutaneous rhGH formulation to build lean body mass, and presented with septic arthritis of right SCJ due to methicillin-sensitive Staphylococcus aureus (MSSA) complicated by a necrotic inflammatory response involving the mediastinum which infiltrated the apical lung parenchyma. The clinical presentation masqueraded as the mediastinal mass raising the suspicion of mediastinal malignancy. Histological analysis of the tissue of SCJ and mediastinal area revealed no malignant cells but a lymphocyte-predominant inflammatory response with germinal centers was observed, which was an atypical response to MSSA bacterial infection. We have reviewed the literature to elucidate the immune-modulatory effect of rhGH, as the chronic use of rhGH by our patient probably has contributed to an atypical immune response to MSSA. The patient was treated with an extended duration of parenteral antibiotics and multiple incision and debridements to achieve complete resolution of infection over the next six months. This is a unique case of septic arthritis of right SCJ in a patient on chronic subcutaneous rhGH which masqueraded as a mediastinal mass raising concern of malignancy; moreover, it highlights the probable immune-modulatory role of rhGH which instigated an atypical immune response to MSSA infection.

MECHANISMS IN ENDOCRINOLOGY: Medical consequences of doping with anabolic androgenic steroids: effects on reproductive functions

Anabolic androgenic steroids (AASs) are appearance and performance-enhancing drugs (APEDs) used in competitive athletics, in recreational sports, and by body-builders. The global lifetime prevalence of AASs abuse is 6.4% for males and 1.6% for women. Many AASs, often obtained from the internet and dubious sources, have not undergone proper testing and are consumed at extremely high doses and in irrational combinations, also along with other drugs. Controlled clinical trials investigating undesired side effects are lacking because ethical restrictions prevent exposing volunteers to potentially toxic regimens, obscuring a causal relationship between AASs abuse and possible sequelae. Because of the negative feedback in the regulation of the hypothalamic-pituitary-gonadal axis, in men AASs cause reversible suppression of spermatogenesis, testicular atrophy, infertility, and erectile dysfunction (anabolic steroid-induced hypogonadism). Should spermatogenesis not recover after AASs abuse, a pre-existing fertility disorder may have resurfaced. AASs frequently cause gynecomastia and acne. In women, AASs may disrupt ovarian function. Chronic strenuous physical activity leads to menstrual irregularities and, in severe cases, to the female athlete triad (low energy intake, menstrual disorders and low bone mass), making it difficult to disentangle the effects of sports and AASs. Acne, hirsutism and (irreversible) deepening of the voice are further consequences of AASs misuse. There is no evidence that AASs cause breast carcinoma. Detecting AASs misuse through the control network of the World Anti-Doping Agency (WADA) not only aims to guarantee fair conditions for athletes, but also to protect them from medical sequelae of AASs abuse.

[Epidemiology of doping in rural gyms in the district of Traunstein]

AIM AND METHOD

To investigate epidemiology of doping in rural gyms, a total of 206 persons doing exercise in 5 different gyms in the district of Traunstein were interviewed.

RESULTS AND CONCLUSION

Nearly 5.0% of the surveyed persons take performance-enhancing drugs, mostly for aesthetic reasons or to rapidly build up strength. There are no gender or education-specific, yet agerelated significant differences in using doping substances. Significant factors influencing the intake of doping agents are the motivation for competition participation, the additional intake of protein supplements and nutritional supplements. 61.5% of the drug-abusers take anabolic steroids (testosterone). One athlete consumes growth hormones. 40.0% of drug-abusers administer medication in the form of an injection, 60.0% in the form of tabs. Costs per intake cycle are between 100 and 150 <euro>. The average body weight gain through the muscle mass increase is approximately 15 kg. Suppliers were friends (36.3%), the Internet (27.3%) and physicians (18.2%). The potential side effects are important cornerstones for the educational work in the prevention of doping.
