Diminished cholesterol efflux mediated by HDL and coronary artery disease in young male anabolic androgenic steroid users

Cardiovascular Disease in Anabolic Androgenic Steroid Users

BACKGROUND

Use of anabolic androgenic steroids (AASs) is associated with increased mortality, and case reports have suggested that some of these deaths are due to cardiovascular disease. However, the epidemiology of cardiovascular disease in AAS users is still relatively unexplored. This study aimed to measure the incidence of cardiovascular disease in male AAS users and to compare these rates with those of a cohort from the general population matched by age and sex.

METHODS

Men sanctioned in an antidoping program for AAS use in Danish fitness centers between 2006 and 2018 were included and matched for age and sex with 50 times as many controls from the general Danish population. The cohort was followed until June 30, 2023. Using the nationwide registries, we obtained information on admissions, prescriptions, educational length, and occupational status for both the AAS users and controls. This study investigated the incidence of acute myocardial infarction, percutaneous coronary intervention, or coronary artery bypass graft, venous thromboembolism, ischemic stroke, arrhythmia, cardiomyopathy, heart failure, and cardiac arrest during the follow-up period.

RESULTS

During an average of 11 years of follow-up, AAS users (n=1189) demonstrated a significantly higher incidence of several cardiovascular events compared with controls (n=59 450). Correspondingly, AASs were associated with an increased risk of acute myocardial infarction (adjusted hazard ratio [aHR] 3.00 [95% CI, 1.67-5.39]), percutaneous coronary intervention or coronary artery bypass graft (aHR 2.95 [95% CI, 1.68-5.18]), venous thromboembolism (aHR 2.42 [95% CI, 1.54-3.80]), arrhythmias (aHR 2.26 [95% CI, 1.53-3.32]), cardiomyopathy (aHR 8.90 [95% CI, 4.99-15.88]), and heart failure (aHR 3.63 [95% CI, 2.01-6.55]). Due to the limited number of ischemic stroke and cardiac arrest cases among AAS users, these outcomes were not reportable.

CONCLUSIONS

AAS use is associated with a substantially increased risk of cardiovascular disease in a large cohort with a long follow-up period.

Possible consequences of the abuse of anabolic steroids on different organs of athletes

Objective: Androgenic steroids abuse among young athletes has long-term health consequences, causing profound damage to vital organs such as the heart, blood vessels, brain, liver, gonads, kidneys, and skin.

Results: In the vessels, steroids cause plaque formation, vascular calcification, thrombosis, and coronary artery disease, and in the heart, they lead to pathological fibrosis, dilated cardiomyopathy, heart failure, fatal ventricular arrhythmias, acute myocardial infarction, and reduced ejection fraction. The brain also suffers from cognitive decline, memory impairment, and a constellation of neurotransmitter abnormalities that lead to depression. In the liver, the consequences are severe and manifest as increased oxidative stress, liver dysfunction, hepatotoxicity, cholestatic jaundice, liver tumours, cell death, and elevations in liver enzymes, bilirubin, and cholesterol. Male athletes experience testicular atrophy, temporary suppression of spermatogenesis, hypogonadism, reduced fertility, infertility, and hormonal imbalance. In contrast, women experience ovarian dysfunction and menstrual irregularities. In the kidney, steroids lead to increased inflammatory cytokines, fibrosis, renal tubular hypertrophy, glomerular changes, and structural damage, and show higher levels of serum creatinine, urinary protein, and cystatin C. In athletes, steroids can lead to various skin problems such as acne, gynecomastia, prostatitis, and alopecia.

Elevated interleukin 8 and matrix metalloproteinase 9 levels are associated with myocardial pathology in users of anabolic-androgenic steroids

AIMS

In the current paper, we aim to explore the effect of both current and former long-term anabolic-androgenic steroid (AAS) use on regulation of systemic inflammatory markers and mediators of extracellular matrix (ECM) remodelling and their association with hormones and echocardiographic myocardial pathology in weightlifters.

METHODS AND RESULTS

In a cross-sectional study, 93 weightlifting AAS users, of whom 62 were current and 31 were past users, with at least 1-year cumulative AAS use (mean 11 ± 7 accumulated years of AAS use), were compared with 54 non-using weightlifting controls (WLCs) using clinical interview, blood pressure measurements, and echocardiography. Serum levels of interleukin (IL)-6, IL-8, tumour necrosis factor (TNF), interferon (IFN)-γ, growth differentiation factor (GDF)-15, and matrix metalloproteinase (MMP)-9, sex hormones, and lipids were analysed. It was found that serum levels of IL-8, GDF-15, and MMP-9 were significantly increased in current AAS users compared with former users and WLCs. Matrix metalloproteinase 9, but not IL-8, correlated consistently with sex hormone levels, and sex hormone levels correlated consistently with mean wall thickness, in current users. Moreover, HDL cholesterol was significantly lower in current vs. former AAS users and significantly inversely correlated with MMP-9 in current users. Further, in current users, MMP-9 and IL-8 correlated with markers of myocardial strain, and MMP-9 also correlated with indices of cardiac mass, which was not seen in former users. Mediation analyses suggested that MMP-9 could partly explain hormone-induced alterations in markers of myocardial damage in current users.

CONCLUSION

Long-term AAS is associated with increased levels of markers of inflammation and ECM remodelling, which seems to have a hormone-dependent (MMP-9) and a hormone-independent (IL-8) association with markers of myocardial dysfunction.

Impact of androgenic anabolic steroid use on cardiovascular and mental health in Danish recreational athletes: protocol for a nationwide cross-sectional cohort study as a part of the Fitness Doping in Denmark (FIDO-DK) study

INTRODUCTION

The use of androgenic anabolic steroids (AASs) among recreational athletes is steadily increasing. However, knowledge regarding the potentially harmful effects of AAS primarily originates from case reports and small observational studies. This large-scale study aims to investigate the impact of AAS use on vascular plaque formation, preclinical coronary disease, cardiac function, circulating cardiovascular risk markers, quality of life (QoL) and mental health in a broad population of illicit AAS users.

METHODS AND ANALYSES

A nationwide cross-sectional cohort study including a diverse population of men and women aged ≥18 years, with current or previous illicit AAS use for at least 3 months. Conducted at Odense University Hospital, Denmark, the study comprises two parts. In part A (the pilot study), 120 recreational athletes with an AAS history will be compared with a sex-matched and age-matched control population of 60 recreational athletes with no previous AAS use. Cardiovascular outcomes include examination of non-calcified coronary plaque volume and calcium score using coronary CT angiography, myocardial structure and function via echocardiography, and assessing carotid and femoral artery plaques using ultrasonography. Retinal microvascular status is evaluated through fundus photography. Cardiovascular risk markers are measured in blood. Mental health outcomes include health-related QoL, interpersonal difficulties, body image concerns, aggression dimensions, anxiety symptoms, depressive severity and cognitive function assessed through validated questionnaires. The findings of our comprehensive study will be used to compose a less intensive investigatory cohort study of cardiovascular and mental health (part B) involving a larger group of recreational athletes with a history of illicit AAS use.

ETHICS AND DISSEMINATION

The study received approval from the Regional Committee on Health Research Ethics for Southern Denmark (S-20210078) and the Danish Data Protection Agency (21/28259). All participants will provide signed informed consent. Research outcomes will be disseminated through peer-reviewed journals and scientific conferences.

Prevention of cardiovascular disease in young adults: Focus on gender differences. A collaborative review from the EAS Young Fellows

A steady rise in cardiovascular morbidity and mortality has been observed in young adults within the last decades. This trend corresponds to an increasing prevalence of traditional cardiovascular risk factors such as obesity and diabetes mellitus type 2 among young adults living in developed countries. Moreover, age-specific risk factors, such as substance abuse, contraceptive medication, and pregnancy-related diseases also correlate with an increased incidence of cardiovascular diseases. In this review, we discuss the available data for young adults on the epidemiology and the rationale for the causality of traditional and newly emerging risk factors of atherosclerotic cardiovascular diseases. We focus on gender-related differences in the exposure to these risk factors, investigate the recent data regarding screening and risk stratification in the young adult population, and describe the current state of the art on lifestyle and therapeutic intervention strategies in the primary prevention setting.

Coronary Inflammation by Computed Tomography Pericoronary Fat Attenuation and Increased Cytokines in Young Male Anabolic Androgenic Steroid Users

BACKGROUND

Anabolic androgenic steroid (AAS) abuse has been associated with coronary artery disease (CAD). Pericoronary fat attenuation (pFA) is a marker of coronary inflammation, which is key in the atherosclerotic process.

OBJECTIVE

To evaluate pFA and inflammatory profile in AAS users.

METHODS

Twenty strength-trained AAS users (AASU), 20 AAS nonusers (AASNU), and 10 sedentary controls (SC) were evaluated. Coronary inflammation was evaluated by mean pericoronary fat attenuation (mPFA) in the right coronary artery (RCA), left anterior descending coronary artery (LAD), and left circumflex (LCx). Interleukin (IL)-1 (IL-1), IL-6, IL-10, and TNF-alpha were evaluated by optical density (OD) in a spectrophotometer with a 450 nm filter. P<0.05 indicated statistical significance.

RESULTS

AASU had higher mPFA in the RCA (-65.87 [70.51-60.70] vs. -78.07 [83.66-72.87] vs.-78.46 [85.41-71.99] Hounsfield Units (HU), respectively, p<0.001) and mPFA in the LAD (-71.47 [76.40-66.61] vs. -79.32 [84.37-74.59] vs. -82.52 [88.44-75.81] HU, respectively, p=0.006) compared with AASNU and SC. mPFA in the LCx was not different between AASU, AASNU, and SC (-72.41 [77.17-70.37] vs. -80.13 [86.22-72.23] vs. -78.29 [80.63-72.29] HU, respectively, p=0.163). AASU compared with AASNU and SC, had higher IL-1, (0.975 [0.847-1.250] vs. 0.437 [0.311-0.565] vs. 0.530 [0.402-0.780] OD, respectively, p=0.002), IL-6 (1.195 [0.947-1.405] vs. 0.427 [0.377-0.577] vs. 0.605 [0.332-0.950] OD, p=0.005) and IL-10 (1.145 [0.920-1.292] vs. 0.477 [0.382-0.591] vs. 0.340 [0.316-0.560] OD, p<0.001). TNF-α was not different between the AASU, AASNU, and SC groups (0.520 [0.250-0.610] vs. 0.377 [0.261-0.548] vs. 0.350 [0.182-430]), respectively.

CONCLUSION

Compared with ASSNU and controls, AASU have higher mPFA and higher systemic inflammatory cytokines profile suggesting that AAS may induce coronary atherosclerosis through coronary and systemic inflammation.

Anabolic-androgenic steroids: How do they work and what are the risks?

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.

Cardiac Complications of Common Drugs of Abuse: Pharmacology, Toxicology and Management

Cardiovascular complications from drugs of abuse are becoming more apparent due to increased usage worldwide. Substance abuse can cause both acute and chronic cardiovascular complications and is increasing in prevalence especially in young adults. These substances contribute to the development of acute coronary syndrome, type II myocardial injury, arrhythmias, cardiomyopathies and have numerous other cardiovascular complications. Although no screening guidelines exist, clinical awareness of these potential complications and their prevention, clinical presentation, diagnosis, and treatment are critically important. Management of cardiovascular disease should be coupled with appropriate social and mental health interventions to provide sustained clinical benefit. The higher the number of substances used recreationally, the greater the risk of premature heart disease. Epidemiological studies showed that 1 in 5 young adults misuse several substances and often start using at younger ages with a greater risk for adverse health outcomes over the long-term. The aim of this review is to highlight the basic epidemiology, cardiac complications, and disease-specific treatment options of commonly abused substances including methamphetamine, cocaine, alcohol, anabolic-androgenic steroids, cannabis, and tobacco.

Mass spectrometry determination of seized oil-based anabolic-androgenic steroids products

INTRODUCTION

The presence of anabolic-androgenic steroids (AAS) in illegal commercial products has been pointed as a global threat for public health. Due the correlation with adverse toxicological effects, there is a growing interest in the implementation of straightforward methods for the determination of AAS in seized products. This work exploited the development of a mass spectrometry approach to characterize the illegal oil formulations containing AAS.

METHODS

The optimization of sample preparation was performed through a simplex-centroid design and the best condition was described as follow: an aliquot of 5 μL of sample were added with 995 μL of acetonitrile and water (75:25, v/v). The solution was vortexed and centrifuged. After that, 10 μL of supernatant were added with 35 μL of acetonitrile and water and internal standard (testosterone-d₃, 1.25 ng). An aliquot of 5 μL was injected into the analytical system.

RESULTS

The method developed was validated and successfully applied in 115 seized samples. Testosterone and its esters had the highest incidence, found in more than 50% of the samples. Besides that, drugs such as boldenone, methandienone, and trenbolone have also been found, where the low quality of the samples was evidenced by the wide variation in the concentration of the drugs, always quantified in sub-doses. Finally, at least one AAS was detected in each sample analyzed. The statistical results were grouped by principal components analysis, to better understand the profile of the seized samples.

CONCLUSION

This work successfully established a fast and simple method for determination of AAS and can be applied to verify the profile of seized samples.

Decreased Native T1 Values and Impaired Myocardial Contractility in Anabolic Steroid Users

Anabolic androgenic steroid (AAS) abuse leads to myocardial toxicity. Human studies are conflicting about the myocardial fibrosis in AAS users. We evaluated cardiac tissue characterization, left ventricle (LV) function, and cardiac structure by cardiovascular magnetic resonance (CMR). Twenty strength-trained AAS users (AASU) aged 29±5 yr, 20 strength-trained AAS nonusers (AASNU), and 7 sedentary controls (SC) were enrolled. Native T1 mapping, late-gadolinium enhancement (LGE), extracellular volume (ECV), and myocardial strain were evaluated. AASU showed lower Native T1 values than AASNU (888±162 vs. 1020±179 ms p=0.047). Focal myocardial fibrosis was found in 2 AASU. AASU showed lower LV radial strain (30±8 vs. 38±6%, p<0.01), LV circumferential strain (-17±3 vs. -20±2%, p<0.01), and LV global longitudinal strain (-17±3 vs. -20±3%, p<0.01) than AASNU by CMR. By echocardiography, AASU demonstrated lower 4-chamber longitudinal strain than AASNU (-15±g3 vs. -18±2%, p=0.03). ECV was similar among AASU, AASNU, and SC (28±10 vs. 28±7 vs. 30±7%, p=0.93). AASU had higher LV mass index than AASNU and SC (85±14 vs. 64±8 vs. 58±5 g/m², respectively, p<0.01). AAS abuse may be linked to decreased myocardial native T1 values, impaired myocardial contractility, and focal fibrosis. These alterations may be associated with maladaptive cardiac hypertrophy in young AAS users.

Boldenone undecylenate disrupts the immune system and induces autoimmune clinical hypothyroidism in rats: Vitamin C ameliorative effects

The present study was designed to evaluate the effects of boldenone undecylenate (BL) abuse alone and in combination with vitamin C (VC) on the immune responses and thyroid structure and function in rats. Thirty adult male Wistar rats were randomly divided into five equal groups and were subjected to various treatment regimens for eight weeks as follows: control group, vehicle control group, VC group orally received VC (120 mg/Kg BW/day), BL-treated group intramuscularly injected with BL (5 mg/kg BW, once/week), and BL+VC group received BL and VC. At the end of this experiment, blood and tissue samples (thyroid, thymus, and spleen) were subjected to hematological evaluation, biochemical analysis, histopathological, and immunohistochemical examinations. In comparison to controls, BL significantly increased the levels of serum proinflammatory interleukins (IL-1 β and IL-6), immunoglobulins (IgG and IgM), and complement 3 but reduced anti-inflammatory interleukin-10, lysosome, and nitric oxide. Besides, altered platelet count and leukogram were evident in BL-injected rats. BL notably disturbed thyroid profile as revealed by a significant increase of thyroid-stimulating hormone and thyroid peroxidase antibody. In contrast, both total and free forms of thyroid hormones (tri-iodothyronine and thyroxine), thyroglobulin, and thyroid peroxidase, were significantly decreased. Moreover, BL caused histopathological changes in the thyroid, thymus, and spleen tissues.CD4⁺ immuno-expression was reduced, but CD8⁺ immunolabelling was increased in both spleen and thymus. The daily dosing of VC to BL-exposed rats significantly corrected most of the deviations in immune parameters. It restored most of the thyroid architecture and function, revealing a significant protective effect of this vitamin. This experimental study demonstrates that BL abusing disrupts the immune system by different mechanisms and addresses BL, for the first time, as an autoimmune clinical hypothyroidism inducer drug. Additionally, VC is helpful in the management of BL abuse.

Consequences of Anabolic-Androgenic Steroid Abuse in Males; Sexual and Reproductive Perspective

The real epidemiology and the possible consequences of anabolic-androgenic steroids (AAS) use still represent a very tricky task due to the difficulties in the quantification and detection of these drugs. Chronic use of AAS, frequently combined with other illicit substances, can induce tremendous negative effects on the reproductive system, but it is also associated with an increased overall and cardiovascular mortality risk. In the present review we summarize and discuss the available evidence regarding the negative impact of AAS on the male reproductive system, providing practical suggestions to manage these problems. For this purpose a meta-analysis evaluating the effects of AAS abusers vs. controls on several hormonal, reproductive and metabolic parameters was performed. In addition, in order to overcome possible limitations related to the combined use of different AAS preparations, we also retrospectively re-analyzed data on animal models treated with supraphysiological dosage of testosterone (T), performed in our laboratory. Available data clearly indicated that AAS negatively affect endogenous T production. In addition, increased T and estradiol circulating levels were also observed according to the type of preparations used. The latter leads to an impairment of sperm production and to the development of side effects such as acne, hair loss and gynecomastia. Furthermore, a worse metabolic profile, characterized by reduced high density lipoprotein and increased low density lipoprotein cholesterol levels along with an increased risk of hypertension has been also detected. Finally sexual dysfunctions, often observed upon doping, represent one the most probable unfavorable effects of AAS abuse.

The effect of transgender hormonal treatment on high density lipoprotein cholesterol efflux capacity

BACKGROUND AND AIMS

A decrease in high-density lipoprotein (HDL)-cholesterol concentrations during transgender hormone therapy has been shown. However, the ability of HDL to remove cholesterol from arterial wall macrophages, termed cholesterol efflux capacity (CEC), has proven to be a better predictor of cardiovascular disease (CVD) largely independently of HDL-concentrations. In addition, the serum capacity to load macrophages with cholesterol (cholesterol loading capacity, CLC) represents an index of pro-atherogenic potential. As transgender individuals are exposed to lifelong exogenous hormone therapy (HT), it becomes of interest to study whether HDL-CEC and serum CLC are affected by HT. HDL-CEC and serum CLC have been evaluated in 15 trans men treated with testosterone and in 15 trans women treated with estradiol and cyproterone acetate at baseline and after 12 months of HT.

METHODS

Total HDL-CEC from macrophages and its major contributors, the ATP-binding cassette transporters (ABC) A1 and ABCG1 HDL-CEC and HDL-CEC by aqueous diffusion were determined by a radioisotopic assay. CLC was evaluated in human THP-1 macrophages.

RESULTS

In trans women, total HDL-CEC decreased by 10.8% (95%CI: -14.3;-7.3; p < 0.001), ABCA1 HDL-CEC by 23.8% (-34.7; -12.9; p < 0.001) and aqueous diffusion HDL-CEC by 4.8% (-8.4;-1.1; p < 0.01). In trans men, only aqueous diffusion HDL-CEC decreased significantly, -9.8% (-15.7;-3.9; p < 0.01). ABCG1 HDL-CEC did not change in either group. Serum CLC and HDL subclass distribution were not modified by HT in both groups.

CONCLUSIONS

Total HDL-CEC decreased during HT in trans women, with a specific reduction in ABCA1 CEC. This finding might contribute to a higher CVD risk.

Anabolic Steroid Use and Aortic Dissection in Athletes: A Case Series

The use of anabolic steroids in supraphysiologic doses has grown in the last decade as doping drugs in athletes. The high dose of anabolic-androgenic steroids (AAS) causes cardiomyopathy, hypertension, thrombosis, myocardial infarction (MI), weakness of connective tissue, and its sequelae such as tendon injury and aortic dissection. Dissection of the ascending aorta is an uncommon injury that has been recognized with increasing frequency in bodybuilders in recent years. It has been proposed that such cases commonly accompany the weakening of connective tissue and must be actively evaluated in the presence of anabolic steroid usage. We present a case series of isolated ascending aorta dissection in athletes who were bodybuilders. All cases were evaluated by transthoracic echocardiography (TTE) and laboratory exams. These cases also served as a reminder of the risks of ascending aorta dissection with AAS, especially in strength athletes who place high demands on their musculoskeletal structures. The results of the current study suggested that anabolic steroid abuse may be associated with detrimental effects on the myocardium represented as cardiomyopathy or atherosclerotic changes in the coronary artery as MI. These findings also strongly suggest that anabolic steroid treatment predisposes the individual to aortic dissection, especially when the patients are exercised.

Anabolic Steroids and Cardiovascular Outcomes: The Controversy

Anabolic steroids (AS) are synthetic derivatives of the male sex hormone testosterone. The use of AS is not limited to bodybuilders and athletes, but non-athletes also use them. It is used to enhance athletic performance, induce muscle hypertrophy, and augment male sexual characteristics. AS use is associated with a wide range of side effects and potential cardiovascular complications. In this article, we have searched the available literature to investigate the association between AS use and cardiovascular disease (CVD). The results revealed that AS was linked to lipid metabolism derangements, hypertension, coagulation disorders, and cardiomyopathy. We concluded, based on the relevant data, that there was evidence that suggests an association with CVD, primarily myocardial infarction, fatal arrhythmias, and cardiomyopathy in AS users. The general population should be informed of the risk. Also, methods of primary and secondary prevention should be implemented to mitigate the risk of CVD secondary to AS.

Comparison of early cardiovascular risk among Brazilian and African university students

Cardiovascular diseases are among the main causes of mortality worldwide, and dyslipidemia is a principal factor risk. Hence the study of biochemical markers is necessary for early diagnosis.

OBJECTIVES

Evaluate biomarkers to diagnose the risks of cardiovascular diseases in healthy Brazilian and African young adults.

DESIGN & METHODS

Weight, height, waist circumference, percentage of body fat and systemic blood pressure were measured; and fasting blood samples were taken for biochemical analysis. Triglycerides, total cholesterol, HDL-c, and apolipoproteins A-I and B were measured on automated equipment using commercially available kits, in addition to the tests of antioxidant capacity of HDL and the enzymatic activity of Paraoxonase 1.

RESULTS

After statistical analysis, it was found that BMI, WC, fat (%), triglycerides, ApoB/ApoA-I ratio and Vmax were higher in Brazilians, while HDL-c, ApoA-I, Lag Time, Vmax and PON1 activity were higher in Africans. In Brazilians, the ApoB/ApoA-I ratio was related to obesity factors and lipid profile, but in Africans it was related only to lipids. The antioxidant capacity of HDL and PON1 activity was better in Africans. Through independence testing, we observed an association with moderate risk of myocardial infarction with gender in Africans. In the binary logistic regression analysis, it was found that men in general - and particularly African men - have higher risk of myocardial infarction than women; Odds Ratio 2144 (CI_95%: 1343-3424) and 2281 (CI_95%: 1082-4811), respectively.

CONCLUSIONS

The anthropometric and biochemical parameters of Brazilians, especially men, predispose them to greater risks of cardiovascular diseases.
