RESUMO

BACKGROUND: The prevalence of anabolic-androgenic steroids (AAS) use is on the rise among athletes and bodybuilders worldwide. In addition to the well-documented adverse effects on hepatic, renal, and reproductive functions, there is an increasing recognition of psychiatric complications associated with AAS use. This study aimed to investigate psychiatric morbidity among male bodybuilders who are AAS users. METHODS: In this cross-sectional study, 25 male bodybuilders using AAS (mean age 31.2 ± 8.9 years) were compared with a control group of 25 healthy male bodybuilders matched in age (31.3 ± 5.5 years). The demographic, hormonal, and biochemical parameters of the participants were recorded. The impact of AAS use on psychiatric morbidity was assessed using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) in both groups. RESULTS: The BDI and BAI scores were significantly higher in male bodybuilders using anabolic-androgenic steroids (p < 0.0001). While the control group showed no instances of anxiety, seven individuals in the AAS user group reported mild anxiety. No participants in the control group exhibited depression, whereas seven AAS users displayed depressive symptoms (4 mild, 3 moderate). Correlations were observed between lactate dehydrogenase (LDH) levels and BAI scores, creatinine levels and both BAI and BDI scores, as well as between estradiol levels and BDI. CONCLUSION: The study concluded that AAS use among male bodybuilders is associated with elevated levels of depression and anxiety. Our findings suggest a potential correlation between anxiety and depression levels and the levels of creatinine, LDH, and estradiol in AAS users.

RESUMO

OBJECTIVE: This systematic review aims to evaluate the optimal treatment for male infertility resulting from Anabolic Androgenic Steroids (AAS) abuse. METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies that compared different protocols for the recovery of spermatogenesis in patients after AAS use were included. RESULTS: 13 studies investigating different protocols to restore spermatogenesis in patients with AAS abuse met the inclusion criteria. The available agents that showed restoration of spermatogenesis include injectable gonadotropins, selective estrogen receptor modulators, and aromatase inhibitors, but their use is still poorly described in the literature. CONCLUSIONS: Clinicians need to be aware of the detrimental effects of AAS on spermatogenesis. AAS-associated infertility may be reversible, but sperm production may take over a year to normalize. Both conservative and aggressive treatment can boost spermatogenesis with positive results. Further understanding of male reproductive endocrinology and high-quality data on the field of restoration of spermatogenesis after AAS abuse are warranted.

RESUMO

BACKGROUND: Recreational use of anabolic-androgenic steroids (AAS) is a public health concern world-wide associated with a range of physical and psychological side effects. Still, people who use AAS tend to be reluctant to seek treatment. This study aims to explore use characteristics, treatment-seeking behaviour, side effects and associated health concerns among men with AAS use. METHODS: The study includes cross-sectional self-report data from 90 men with a current or previous use of AAS exceeding 12 months, where 41 (45.6%) had sought treatment at least once during their lifetime, and 49 (54.4%) had not. Health service engagement was examined with descriptive statistics on reasons for contacting health services, transparency about AAS use, satisfaction with health services and reasons for not seeking treatment. Furthermore, experienced side effects and health concerns were compared between the treatment seeking and the non-treatment seeking group, using two-sample t-tests and Chi2 or Fisher exact tests for numerical and categorical variables, respectively. RESULTS: All 90 AAS-using men reported side effects from AAS use. Treatment seekers were significantly younger, experienced more side effects including gynecomastia, excessive sweating, fatigue, depression and anxiety, and expressed more concern for testosterone deficiency. Preventive health check-up was the most common reason for seeking treatment (n = 22, 53.7%), and 38 men (93%) were transparent about AAS use during consultations with health professionals. The main reported reasons for not seeking healthcare services were that the experienced side effects were not considered to be of treatment demanding nature (n = 39, 79.6%) and the belief that healthcare providers had scarce knowledge about AAS use and its health impacts (n = 12, 24.5%). CONCLUSIONS: Reluctance to seek treatment among people who use AAS, despite having associated side effects and health concerns, may contribute to continued health risks. It is important to fill the knowledge gap on how to reach and treat this new patient group, and policy makers and treatment providers need to be educated on how to meet their treatment needs.

RESUMO

Anabolic androgenic steroids (AASs) are a group of molecules including endogenous testosterone and synthetic derivatives that have both androgenic and anabolic effects. These properties make them therapeutically beneficial in medical conditions such as hypogonadism. However, they are commonly bought illegally and misused for their anabolic, skeletal muscle building, and performance-enhancing effects. Supraphysiologic and long-term use of AASs affects all organs, leading to cardiovascular, neurological, endocrine, gastrointestinal, renal, and hematologic disorders. Hepatotoxicity is one of the major concerns regarding AASs treatment and abuse. Testosterone and its derivatives have been most often shown to induce a specific form of cholestasis, peliosis hepatis, and hepatic benign and malignant tumors. It is currently believed that mechanisms of pathogenesis of these disorders include disturbance of antioxidative factors, upregulation of bile acid synthesis, and induction of hepatocyte hyperplasia. Most toxicity cases are treated with supportive measures and liver function normalizes with discontinuation of AAS. However, some long-term consequences are irreversible. AAS-induced liver injury should be taken in consideration in patients with liver disorders, especially with the increasing unintentional ingestion of supplements containing AAS. In this paper, we review the most current knowledge about AAS-associated adverse effects on the liver, and their clinical presentations, prevalence, and pathophysiological mechanisms.

RESUMO

INTRODUCTION: Endogenous testosterone deficiency or excess anabolic-androgenic steroids (AAS) have been linked to alter the physiology of different organs in the body, more specifically, the vasculature of coronary arteries. Despite the health-related concerns of using synthetic testosterone derivatives, such as AAS, there has been a tremendous increase in the use of AAS among athletes and bodybuilders. AREAS COVERED: We have highlighted the three main mechanisms that AAS increase the risk of coronary artery disease (CAD): altering the homeostasis of lipid metabolism which results in dyslipidemia and subsequently atherosclerosis, disturbing the function of platelet which results in platelet aggregation and subsequent thrombosis, and increasing the risk of coronary vasospasm by affecting the physiological function of vascular bed. EXPERT OPINION: Despite the restriction of AAS in specific clinical conditions such as testosterone deficiency and cancer therapy, many amateurs' athletes misuse the AAS. Although there has been a strong association between the AAS misuse and risk of developing CAD, the more valued approach would be a randomized clinical double-blind trial. The suggested primary endpoint would be an occurrence of adverse cardiovascular events, such as myocardial infarction, cerebrovascular accidents, and death. Increasing awareness of the risk of missing AAS among high-risk groups is imperative.

RESUMO

Despite the well-documented effects of testosterone and its synthetic derivatives-collectively termed anabolic androgenic steroids (AASs)-on the musculoskeletal system, the therapeutic use of these agents has received limited investigation within the field of orthopaedic surgery. In the last 2 decades, preclinical and clinical research has started to identify promising applications of the short-term use of AASs in the perioperative period. There is evidence to suggest that AASs may improve postoperative recovery after anterior cruciate ligament reconstruction and total joint arthroplasty. In addition, AASs may augment the biological healing environment in specific clinical scenarios including muscle injury, fracture repair, and rotator cuff repair. Current literature fails to present strong evidence for or against the use of AASs in orthopaedics, but there is continuous research on this topic. The purpose of this study was to provide a comprehensive overview of the current status of AAS applications in orthopaedic surgery, with an emphasis on preclinical data, clinical studies, and future directions.

RESUMO

Anabolic-androgenic steroids (AAS) are a class of hormones that are widely abused for their muscle-building and strength-increasing properties in high, nontherapeutic, dosages. This review provides an up-to-date and comprehensive overview on how these hormones work and what side effects they might elicit. We discuss how AAS are absorbed into the circulation after intramuscular injection or oral ingestion and how they are subsequently transported to the tissues, where they will move into the extravascular compartment and diffuse into their target cells. Inside these cells, AAS can biotransform into different metabolites or bind to their cognate receptor: the androgen receptor. AAS and their metabolites can cause side effects such as acne vulgaris, hypertension, hepatotoxicity, dyslipidemia, testosterone deficiency, erectile dysfunction, gynecomastia, and cardiomyopathy. Where applicable, we mention treatment options and self-medication practices of AAS users to counteract these side effects. Clinicians may use this review as a guide for understanding how AAS use can impact health and to assist in patient education and, in some cases, the management of side effects.

RESUMO

Abstract Background: The use of androgenic anabolic steroids (AAS) is prevalent among young bodybuilders, motivated by aesthetic results. Although the medical community condemns this practice for its potential deleterious effect, we must recognize the need for more scientific research on the likelihood and magnitude of the adverse events. Objective: To evaluate whether high-quality, scientific evidence supports that AAS negatively affect lipid profile and promote muscle hypertrophy in resistance training practitioners. Methods: A systematic review of the literature of randomized clinical trials was conducted in the PubMed / Medline, Scielo and Science direct databases. The searches were conducted by two independent researchers by June 2018. A significance level of 5% was considered in the analysis. Results: Six clinical trials involving 170 resistance training practitioners were included. A significant heterogeneity was found in studies evaluating the effects of AAS on lipid profile and muscle hypertrophy (I² = 97, 95 and 91%, respectively), with no significant effects on HDL-cholesterol (-5.62mg/dL, 95%CI −12.10, 0.86, p= 0.09), LDL-cholesterol (7.76 mg/dL, 95%CI −9.70, 25.23, p= 0.57) and muscle hypertrophy (2.44kg 95%CI 0.02, 4.86, p=0.05). Conclusion: Current evidence does not support that low-to-moderate doses of AAS cause serious negative effects on lipid profile or promote muscle hypertrophy in resistance training practitioners.

RESUMO

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.

RESUMO

INTRODUCTION: Introduction: indiscriminate use of anabolic steroids is associated with cardiovascular diseases, renal damage, and hepatic toxicity. Contrastingly, nutraceutical foods such as avocados prevent and control several diseases, as they can reduce the effects of oxidative stress. Objective: this study evaluates the benefits of consuming an avocado oil-based diet to attenuate the systemic damage caused by supraphysiological doses of testosterone, by analyzing the biochemical profile of 28 42-day-old male Wistar rats. Methods: silicone pellets containing testosterone were surgically implanted, and they received control or avocado oil-based feed. After 20 weeks, all the male rats were anesthetized and their blood samples collected. Results: although the high hormone concentration had a negative influence on the biochemical profile of these animals, the groups that consumed avocado oil exhibited a reduction in serum triacylglycerols (-21 %; p = 0.0001), VLDL (-20 %; p = 0.0085), LDL (-78 %; p < 0.0001), and total cholesterol (-12 %; p < 0.0001), along with positive changes in their HDL concentrations (+7 %; p = 0.001). The avocado oil groups also manifested a reduction in the total concentration of serum proteins (-24 %; p = 0.0357), albumin (-26 %; p = 0.0015), urea (-14 %; p = 0.04), and creatinine (-33 %; p < 0.0001). The concentration of liver transaminases was found to be higher in the animals included in the induced group (ALT, +66 %; p = 0.0005, and AST, +23 %; p = 0.0021), whereas they remained stable in the avocado oil group. Conclusion: from the above, it may be concluded that supraphysiological doses of testosterone are related to increased risk factors for cardiovascular, renal, and hepatic diseases, and that the consumption of avocado oil shields the biochemical profile, thus reducing the associated risk factors.


INTRODUCCIÓN: Introducción: el uso indiscriminado de esteroides anabólicos se asocia con enfermedades cardiovasculares, daño renal y toxicidad hepática. En cambio, los alimentos nutracéuticos como el aguacate previenen y controlan varias enfermedades, ya que pueden reducir los efectos del estrés oxidativo. Objetivo: este estudio evalúa los beneficios de consumir una dieta basada en aceite de aguacate para atenuar el daño sistémico causado por dosis suprafisiológicas de testosterona mediante el análisis del perfil bioquímico de 28 ratas Wistar macho de 42 días de edad. Métodos: se implantaron quirúrgicamente perdigones de silicona que contenían propionato de testosterona y los animales recibieron una alimentación de control o una basada en el aceite de aguacate. Después de 20 semanas se anestesiaron todos los animales y se recogieron sus muestras de sangre. Resultados: aunque la alta concentración de hormonas tuvo una influencia negativa en el perfil bioquímico de estos animales, los grupos que consumieron aceite de aguacate mostraron una reducción de los triglicéridos séricos (-21 %; p = 0,0001), las VLDL (-20 %; p = 0,0085), las LDL (-78 %; p < 0,0001) y el colesterol total (-12 %; p < 0,0001), con cambios positivos en las LDL (+7 %; p = 0,001). Los grupos alimentados con aceite de aguacate manifestaron una reducción de la concentración total de proteínas séricas (-24 %; p = 0,0357), albúmina (-26 %; p = 0,0015), urea (-14 %; p = 0,04) y creatinina (-33 %; p < 0,0001). Se encontró que la concentración sérica de transaminasas hepáticas era mayor en los animales del grupo inducido (ALT: +66 %; p = 0,0005, y AST: +23 %; p = 0,0021), mientras que en los grupos con aceite de aguacate, los parámetros hepáticos se mantuvieron estables. Conclusión: de todo ello se puede concluir que las dosis suprafisiológicas de testosterona están relacionadas con un aumento de los factores de riesgo de sufrir enfermedades cardiovasculares, renales y hepáticas, y que el consumo de aceite de aguacate protege el perfil bioquímico, lo que reduce los factores de riesgo asociados.

RESUMO

Anabolic-androgenic steroids (AASs) can be used to treat both hormonal diseases and other pathologies characterized by muscle loss (aging, cancer, and AIDS). Even if the adverse effects related to the misuse of AASs have been well studied in different systems and apparatuses, knowledge about brain damage is poor.In this scenario, this experimental study aimed to analyze the role of several microRNAs (miRNAs) in brain damage after AAS misuse, to better comprehend the underlying mechanisms. The research hypothesis at the base of this experimental study is that the chronic use of AASs may be associated to brain damage with a dysregulation of these miRNAs. Moreover, miRNA expression values were compared among three different groups, "AAS" group, "Cocaine" group and "Aging" group, in order to define if AAS brain damage can be compared with the brain impairment linked to aging and/or cocaine assumption.This experimental study revealed that the tested miRNAs (hsa-miR-21-5p, hsa-miR-34a-5p, hsa-miR-124-5p, hsa-miR-132-3p, and hsa-miR-144-3p) were overexpressed in all enrolled groups. In the light of the presented results, the identification of specific circulating and/or tissue biomarkers is challenging for the scientific community. Further studies with larger samples are needed to confirm these interesting findings.

RESUMO

INTRODUCTION: Anabolic steroids are widely administered to patients with aplastic anemia (AA) and are associated with numerous medical complications. To assist with future diagnoses, we report about a young boy with multiple hepatocellular adenomas (HAs) induced by long-term use of anabolic androgenic steroids (AAS) for AA and present a related literature review. PATIENT CONCERN: A 15-year-old boy who was diagnosed with AA in 2011 had been treated with stanozolol (6 mg per day) and ciclosporin A (120-150 mg per day) for almost 4 years. He presented with epigastric pain and fever, and abdominal computed tomography showed a lesion of heterogenous density measuring 13.5 × 13.0 × 8.0 cm in the left hepatic lobe, which was initially misdiagnosed as a liver abscess. DIAGNOSIS: The patient went into hemorrhagic shock twice after invasive manipulation that aimed at diagnosis and was finally diagnosed with HA using fine needle aspiration. INTERVENTIONS: The patient discontinued AAS and only reserved ciclosporin A for AA treatment. OUTCOMES: Follow-up abdominal computed tomography performed 4 years after AAS discontinuation showed obvious regression of the hepatic lesions. CONCLUSION: It is of great importance for hematologists to completely understand that the long-term use of AAS may cause HA, which carries a great risk of hemorrhage and malignant transformation.

RESUMO

Anabolic steroids (AS) are synthetic testosterone-derivatives developed by the pharmaceutical industry to mimic testosterone biological effects. So far, AS have been implicated in the treatment of pathological conditions, such as hypogonadism, anemia, and cachexia. Since their discovery, though, AS have been illicitly used by elite and recreational athletes, bodybuilders and weightlifters in order to enhance athletic and aesthetic performance. This practice is characterized by cycles of administration and withdrawal, the combination of different AS compounds, and administration of doses 50 - 1000 times higher than those recommended for therapeutic purposes. AS excess has been correlated to cardiovascular detrimental effects, including cardiac hypertrophy, arrhythmias, and hypertension. Particularly, acute myocardial infarction (AMI) has been extensively reported by clinical and post-mortem studies. Atherosclerosis, hypercoagulability state, increased thrombogenesis and vasospasm have arisen as potential causes of myocardial ischemia in AS users. Additionally, several experimental reports have demonstrated that AS can increase the susceptibility to cardiac ischemia/reperfusion injury, whereas the cardioprotection elicited by physical exercise and ischemic postconditioning is blunted. Altogether, these factors can contribute to increased AMI morbidity and mortality during AS excess, particularly when AS are combined with other compounds, such as thyroid hormones, growth hormones, insulin, and diuretics.

RESUMO

Necrotizing sialometaplasia is a benign, self-limiting, inflammatory disease of salivary glands, mainly involving the minor salivary glands in the palate. This lesion can mimic a malignant neoplasm, both clinically and histopathologically, manifesting as a submucosal swelling or as an ulcer of the palate. This report presents a case of an otherwise healthy bodybuilder with anabolic androgenic steroids abuse with bilateral necrotizing sialometaplasia in the palate, and discusses computed tomography findings in the pre-ulceration phase. Literature review revealed another two cases of necrotizing sialometaplasia with preoperative imaging, both performed in the ulceration phase. The importance of radiographic findings as an aid in differential diagnosis is further discussed, as well as the role of possible predisposing factors including anabolic androgenic steroids abuse in the pathogenesis of necrotizing sialometaplasia.

RESUMO

BACKGROUND: An individual is considered HIV positive when a confirmatory HIV-1/HIV-2 differentiation test returns positive following an initial reactive antigen/antibody combination screen. Falsely reactive HIV screens have been reported in patients with various concomitant infectious and autoimmune conditions. Falsely positive confirmatory HIV differentiation assays are seen less frequently, but have been observed in cases of pregnancy, pulmonary embolism, and malaria. CASE PRESENTATION: A healthy 27 year-old man was referred after a reactive ADVIA Centaur® HIV Ag/Ab screen and positive Bio-Rad Geenius™ HIV 1/2 Confirmatory assay, suggesting HIV-1 infection. The patient's HIV viral load was undetectable prior to initiation of antiretroviral therapy, and remained undetectable on subsequent testing after initiation of antiretroviral therapy. Both Centaur® and Geenius™ tests were repeated and returned reactive. As this patient was believed to be at low risk of acquiring HIV infection, samples were additionally run on Genscreen™ HIV-1 Ag assay and Fujirebio Inno-LIA™ HIV-1/2 score, with both returning non-reactive. For confirmation, the patient's proviral HIV DNA testing was negative, confirming the initial results as being falsely positive. The patient disclosed that he had been using a variety of anabolic steroids before and during the time of HIV testing. DISCUSSION AND CONCLUSIONS: The erroneous diagnosis of HIV can result in decreased quality of life and adverse effects of antiretroviral therapy if initiated, hence the importance of interpreting the results of HIV testing in the context of an individual patient. This reports suggests a potential association between the use of anabolic steroids and falsely-reactive HIV testing.
