Toxicol Res (Camb) 2024; 13:tfae042. [PMID: 38529199 PMCID: PMC10960923 DOI: 10.1093/toxres/tfae042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/13/2024] [Accepted: 03/07/2024] [Indexed: 03/27/2024] Open
Abstract
Millions of individuals have used illicit anabolic-androgenic steroids (AAS), but the long-term cardiovascular associations of these drugs remain incompletely understood. Boldjan is AAS medication which is used in veterinary medicine and by young adults aiming to have a better appearance improving their self-esteem. Therefore; the objective of the current investigation was to examine any potential preventative effects of amygdalin extract against anabolic steroid Boldjan induced cardic toxicity, injury and oxidative stress in male rat. Forty adult male Wistar rats were classified into five groups (Gp1, Control Gp; Gp2, Amygdalin Gp in which rats treated with amygdalin (100 mg/kg body weight/day) daily for 2 weeks; Gp3, Boldjan Gp in which rats treated with Boldjan (10 mg/Kg BW/week) for 4 weeks; Gp4, Boldjan + Amygdalin). Boldjan induced a significant rises in serum lactate dehydrogenase (LDH), creatine kinase (CK) and creatine kinase MB (CK MB), aspartate aminotransferase (AST), total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), and very-low-density lipoprotein-cholesterol (VLDL-C), cardiac injury, and malondialdehyde (MDA) levels and a significant depletion in serum high-density lipoprotein-cholesterol (HDL-C), cardiac reduced glutathione (GSH), Superoxide dismutase (SOD) and catalase (Cat) activities as compared to control Gp. In contrast, Amygdalin significantly reversed the Boldjan induced cardiac toxicity in post treated rats Gp (Boldjan + Amygdalin). Amygdalin could be an efficient preventive supplement for mitigating Boldjan induced cardiac toxicity, possibly via controlling oxidative stress events.

Karagun B. Carotid intima media thickness as a marker of increased cardiovascular risk due to androgenic anabolic steroids in male bodybuilders: a cross-sectional study. J Sports Med Phys Fitness 2024; 64:311-317.

Abstract
BACKGROUND The usage of androgenic-anabolic steroids (AAS) leads to severe side effects. The aim of our study was to investigate the effects of AAS on the increase in the carotid intima-media thickness which is regarded as predictor of cardiovascular disorders and determine the association of ASS usage to urinary, hepatic, and hematological systems as well as lipid disorders. METHODS A total of 60 male bodybuilders (30 AAS users with a mean age of 31.2±8.9 years and 30 AAS nonusers with a mean age of 31.2±8.9 years) were assessed in this cross-sectional study. The patients' demographic, radiologic, hormonal, and biochemical parameters were recorded. The carotid intima-media thickness (CIMT) was measured using B-mode ultrasound in both groups. Abdominal ultrasonography was used to assess for the presence of fatty liver. RESULTS CIMT was significantly increased in AAS (0.72±0.13 mm) users than in the controls (0.47±0.07 mm) (P<0.001). The mean duration of AAS usage was 2.70±2.13 years. There was a statistically significant positive correlation between the duration of AAS usage and CIMT (r=0.710; P<0.001). A statistically significant negative correlation among HDL, LH, and CIMT was found in the correlation analysis between biochemical parameters and CIMT among AAS users (respectively, r and P values were: r=0.399; P=0.029; r=-0.366; P=0.047; r=-0.287; P=0.035). Likewise, a negative correlation (r=-0.425; P=0.019) was found between FSH and CIMT. CONCLUSIONS We found that the usage of AAS among male bodybuilders has led to an increase in CIMT, which is associated with poor cardiovascular health. The results of our study highlight the vital importance of educating male bodybuilders who use these chemicals about the side effects.

Abstract
BACKGROUND Supra-physiologic doses of anabolic androgenic steroids (AAS) lead to multiple cardiovascular complications. The long-term clinical effect of AAS overuse on cardiac structure and function, which persists during off-cycle periods, remains unclear. METHODS A total of 15 sedentary subjects and 79 bodybuilders (26 AAS non-users and 53 AAS-users), matched for age and male gender, were assessed in a cross-sectional design for echocardiography measures. AAS-users were included during an off-cycle phase, abstained from AAS for at least 1 month. 2D standard M-mode and speckle tracking echocardiography were used to measure cardiac dimensions and functions. RESULTS Inter-ventricular septum and posterior wall thickness were significantly higher among chronic off-cycle AAS-users compared to AAS non-users and sedentary group. Off-cycle AAS-users showed lower E/A ratio of the diastolic function. Left ventricular systolic function was not affected in terms of ejection fraction, but significant subclinical systolic dysfunction, assessed by GLS, was observed for chronic off-cycle AAS-users compared to AAS non-users (GLS = -16.8% vs. -18.5%, respectively; p = 0.001). Diameter of left atrium and right ventricle were significantly enlarged among off-cycle AAS-user bodybuilders (p = 0.002 and 0.040). TAPSE and RV S', and cardiac vasculature of aorta were comparable in all groups. CONCLUSIONS This study demonstrates that during off-cycle phase, AAS-users show long-term impaired GLS, even after considerable AAS abstain, despite normal LVEF. It highlights the importance of following GLS to predict hypertrophy and heart failure events, and not relying on LVEF alone. In addition, the hypertrophic effect of chronic AAS consumption is transitional during AAS washout periods.

Abstract
Coordinated molecular responses are key to effective initiation and resolution of both acute and chronic inflammation. Vascular inflammation plays an important role in initiating and perpetuating atherosclerotic disease, specifically at the site of plaque and subsequent fibrous cap rupture. Both men and women succumb to this disease process, and although management strategies have focused on revascularization and pharmacological therapies in the acute situation to reverse vessel closure and prevent thrombogenesis, data now suggest that regulation of host inflammation may improve both morbidity and mortality, thus supporting the notion that prevention is better than cure. There is a clear sex difference in the incidence of vascular disease, and data confirm biological differences in inflammatory initiation and resolution between men and women. This article reviews contemporary opinions describing the sex difference in the initiation and resolution of inflammatory responses, with a view to explore potential targets for pharmacological intervention.

Abstract
Anabolic substances have been increasingly used by bodybuilders and athletes with the goal of improving performance and aesthetics. However, this practice has caused some concern to physicians and researchers because of unknowledge of consequences that the indiscriminate and illicit use of these substances can cause. Thus, this study analyzed the effects of two commercially available anabolic steroids (AS), Winstrol Depot® (Stanozolol) and Deposteron® (Testosterone Cypionate), in the neuronal density of limbic, motor and sensory regions on the cerebral cortex and in CA1, CA2, CA3 regions of the hippocampus. A total of 60 Swiss mice were used (30 males and 30 females), separated into three groups: control and two experimental groups, which received the AAS. From each brain, homotypic and semi-serial samples were taken in frontal sections from areas established for the study. The results showed that females treated with testosterone cypionate presented a reduction in all regions tested and the ones treated with Stanozolol showed a decrease in some hippocampal areas. Regarding male animals, stanozolol led to a decrease in neuron number in one hippocampal region. These data allow us to conclude that supra-physiological doses of steroids used in this study, can cause considerable damage to nervous tissue with ultrastructural and consequently behavioral impairment. These changes could interfere with the loss of physical yield and performance of athletes and non-athletes and may cause irreparable damage to individuals making irresponsible use of anabolic steroids.

Abstract
Nandrolone decanoate (ND) is a commonly used anabolic-androgenic steroid. These drugs are illegally self-administered by athletes to enhance their sports performance. However, their abuse could influence the testicular function and fertility. The main objective of this study was to evaluate the possible protective effects of Cynara scolymus leaf extract (CLE) on ND-induced testicular dysfunction in rats. Five groups of adult male rats (10 rats each) were used. Group I rats received only saline and served as controls. Group II rats were injected with a vehicle once weekly, while group III rats received intramuscular injections of ND (20 mg/kg/week for 60 days). Group IV rats orally received 1 g/kg/day of CLE and group V rats received ND and CLE at the aforementioned doses. The results revealed that ND has a negative impact on the testicular function as evidenced by the significant increases (p ≤ 0.05) in testicular malondialdehyde concentration and serum non-prostatic acid phosphatase activity, as well as the significant decreases in serum testosterone levels, testicular weight, glutathione concentration, catalase enzyme activity, and total antioxidant capacity. These results were accompanied by considerable alterations of sperm characters and histopathological studies of the testicular tissue. However, co-treatment with CLE extract significantly alleviated (p ≤ 0.05) almost all ND-induced pathological alterations. In conclusion, co-treatment of ND-intoxicated rats with CLE ameliorated the toxic effects of ND on the testicular structure and function, probably due to its antioxidant activity.

Abstract
Sex differences exist in how cerebral blood vessels function under both physiological and pathological conditions, contributing to observed sex differences in risk and outcomes of cerebrovascular diseases (CBVDs), such as vascular contributions to cognitive impairment and dementia (VCID) and stroke. Throughout most of the lifespan, women are protected from CBVDs; however, risk increases following menopause, suggesting sex hormones may play a significant role in this protection. The cerebrovasculature is a target for sex hormones, including estrogens, progestins, and androgens, where they can influence numerous vascular functions and pathologies. While there is a plethora of information on estrogen, the effects of progestins and androgens on the cerebrovasculature are less well-defined. Estrogen decreases cerebral tone and increases cerebral blood flow, while androgens increase tone. Both estrogens and androgens enhance angiogenesis/cerebrovascular remodeling. While both estrogens and androgens attenuate cerebrovascular inflammation, pro-inflammatory effects of androgens under physiological conditions have also been demonstrated. Sex hormones exert additional neuroprotective effects by attenuating oxidative stress and maintaining integrity and function of the blood brain barrier. Most animal studies utilize young, healthy, gonadectomized animals, which do not mimic the clinical conditions of aging individuals likely to get CBVDs. This is also concerning, as sex hormones appear to mediate cerebrovascular function differently based on age and disease state (e.g. metabolic syndrome). Through this review, we hope to inspire others to consider sex as a key biological variable in cerebrovascular research, as greater understanding of sex differences in cerebrovascular function will assist in developing personalized approaches to prevent and treat CBVDs.

Abstract
Anabolic androgenic steroids (AAS) are performance enhancing drugs commonly used by athletes and bodybuilders to improve appearance and athletic capability. Unfortunately, these testosterone derivatives can be associated with serious and potentially irreversible side effects, and can impact multiple organ systems. It is important that physicians be familiar with these adverse consequences so that they can appropriately counsel patients whom they suspect of AAS-abuse. In this chapter, we will review the negative effects of these compounds on various organ systems in men using AAS.

Abstract
Anabolic Androgenic Steroids (AASs) misuse has increased among adolescents and recreational athletes due to their potential effects on muscle hypertrophy. On the other hand, AAS might induce alterations on cardiovascular system, although some controversies regarding AAS on vascular properties remain unknown. To address this question, we aimed to investigate the effects of high doses of nandrolone combined with strenuous resistance training (RT) on function and structure of thoracic aorta. Rats were randomized into four groups: non-trained vehicle (NTV), trained vehicle (TV), non-trained nandrolone (NTN), and trained nandrolone (TN), and submitted to 6 weeks of treatment with nandrolone (5 mg/kg, twice a week) and/or resistance training. In vitro response of thoracic aorta to acetylcholine (ACh) was analyzed. Vascular nitric oxide (NO) and reactive oxygen species (ROS) synthesis were evaluated using 4,5-diaminofluorescein diacetate (DAF-2) and hydroethidine fluorescent techniques, respectively. Thoracic aorta was processed for microscopy analyses and tunica media thickness was measured. ACh-mediated relaxation response was impaired in endothelium intact aortic rings isolated from trained rats (TV and TN) as compared with their matched non-trained groups. TN rats showed reduced ACh-mediated vasodilatation than NTN rats. NO production and bioavailability decreased in thoracic aorta of nandrolone-treated rats in relation to their matched non-trained group (NTN vs. NTV; TN vs. TV). ROS production and tunica media thickness were increased in TN rats when compared with TV rats. These findings indicate that high doses of nandrolone combined with strenuous RT affect NO bioavailability and might induce endothelial dysfunction and arterial morphological alterations.

Abstract
Anabolic androgenic steroids (AAS) are recommended for therapeutic clinic, but their use has increased in recent decades for aesthetic reasons. No study has evaluated the impact of AAS in the fallopian tube, after treatment and recovery periods. Herein, the aim of study was to investigate the effects of Nandrolone Decanoate (ND), administered in different doses (1.87; 3.75; 7.5 and 15 mg/kg) on the ampulla of the fallopian tube in rats, following post-treatment (PT; 15 consecutive days) and post-recovery (PR; 30 consecutive days) periods. The control group received mineral oil. Estrous cycle was monitored daily during both periods and in sequence the rats (n = 8/group/period) were killed. All ND-treated animals showed estral acyclicity during the PT and PR periods, but the histomorphometric changes in the fallopian tube varied according to the ND dose level. The expression of AR, ERα and ERβ varied in the nucleus and cytoplasm of epithelial cells. No AR expression was observed in the stroma. The muscle cells exhibited variation in immunostaining. In conclusion, ND promoted histomorphometric and immunohistochemical changes in the ampullary portion of the fallopian tube after treatment and recovery periods in a dose-independent manner.

Abstract
Nandrolone Decanoate (ND) is an Anabolic Androgenic Steroid (AAS) that under abusive regimen can lead to multiple physiological adverse effects. Studies of AAS-mediated cardiovascular (CV) alterations were mostly taken from male subjects, even though women are also susceptible to the effects of AAS and gender-specific differences in susceptibility to vascular diseases exist. Here we investigate ND-induced vascular reactivity alterations in both sedentary and exercised female rats and whether these alterations depend on endothelium-derived factors. We show that chronic exposure of female Wistar rats to ND (20mg/Kg/week for 4weeks) impaired the vascular mesenteric bed (MVB) reactivity to vasodilator (acetylcholine) agonist. The endothelium-dependent Nitric Oxide (NO) component was reduced in ND-treated rats, whereas neither the endothelium-derived hyperpolarizing factor (EDHF) component nor prostanoids were altered in the MVBs. Endothelial dysfunction observed in ND-treated rats was associated with decreased eNOS (Ser1177) and Akt (Ser473) phosphorylation sites and upregulation of iNOS and NADPH oxidase expression. Exercise training by weight lifting in water did not improve the vascular alterations induced by ND treatment. ND treatment also significantly reduced the serum levels of estradiol in females, overriding its CV protective effect. These results help uncover the role of ND modulating endothelial function in the setting of CV disease caused by the abuse of AAS in females. If this translates to humans, young women abusing AAS can potentially lose the cardio protective effect rendered by estrogen and be more susceptible to CV alterations.

Abstract
The use of doping substances and methods is extensive not only among elite athletes, but also among amateur and recreational athletes. Many types of drugs are used by athletes to enhance performance, to reduce anxiety, to increase muscle mass, to reduce weight or to mask the use of other drugs during testing. However, the abuse of doping substances and methods has been associated with the occurrence of numerous health side-effects. The adverse effects depend on the type of the consumed drug, as well as the amount and duration of intake and the sensitivity of the body, since there is a large inter-individual variability in responses to a drug. Usually the doses used in sports are much higher than those used for therapeutic purposes and the use of several drugs in combination is frequent, leading to higher risk of side-effects. Among biomedical side-effects of doping, the cardiovascular ones are the most deleterious. Myocardial infarction, hyperlipidemia, hypertension, thrombosis, arrythmogenesis, heart failure and sudden cardiac death have been noted following drug abuse. This paper reviews the literature on the adverse cardiovascular effects after abuse of prohibited substances and methods in athletes, aiming to inform physicians, trainers and athletes and to discourage individuals from using drugs during sports.

Abstract
Doping -the abuse of anabolic-androgenic steroids in particular- is widespread in amateur and recreational sports and does not solely represent a problem of professional sports. Excessive overdose of anabolic steroids is well documented in bodybuilding or powerlifting leading to significant side effects. Cardiovascular damages are most relevant next to adverse endocrine effects.Clinical cases as well as forensic investigations of fatalities or steroid consumption in connection with trafficking of doping agents provide only anecdotal evidence of correlations between side effects and substance abuse. Analytical verification and self-declarations of steroid users have repeatedly confirmed the presumption of weekly dosages between 300 and 2000 mg, extra to the fact that co-administration of therapeutics to treat side-effects represent a routine procedure. Beside the most frequent use of medications used to treat erectile dysfunction or estrogenic side-effects, a substantial number of antihypertensive drugs of various classes, i.e. beta-blockers, diuretics, angiotensin II receptor antagonists, calcium channel blockers, as well as ACE inhibitors were recently confiscated in relevant doping cases. The presumptive correlation between misuse of anabolic steroids and self-treatment of cardiovascular side effects was explicitly confirmed by detailed user statements.Two representative fatalities of bodybuilders were introduced to outline characteristic, often lethal side effects of excessive steroid abuse. Moreover, illustrative autopsy findings of steroid acne, thrombotic occlusion of Ramus interventricularis anterior and signs of cardiac infarctions are presented.A potential steroid abuse should be carefully considered in cases of medical consultations of patients exhibiting apparent constitutional modifications and corresponding adverse effects. Moreover, common self-medications -as frequently applied by steroid consumers- should be taken into therapeutic considerations.

Abstract
This study tested the hypothesis that different doses of nandrolone decanoate (ND) will cause changes in the estrous cycle and ovarian tissue of adult rats; and investigated the duration of the recovery period that is sufficient to restore the damage in the animals treated with different doses. Wistar rats were treated with ND at doses of 1.87, 3.75, 7.5 and 15 mg/kg body weight, or received mineral oil (control group) for 15 days, subcutaneously. All animals were divided into three groups according to the treatment periods: (i) ND treatment for 15 days; (ii) ND treatment followed by a 30-day recovery; and (iii) ND treatment followed by a 60-day recovery. Estrous cycle was monitored daily, and at the end of each period, the animals were euthanized for histopathological analysis. During ND treatment and after 30-day recovery, all animals exhibited persistent diestrus. After a 60-day recovery, persistent diestrus was only maintained in the group that had received the highest dose. Ovarian weight was decreased significantly after the 30-day recovery, regardless of ND doses, compared with the control group. There was a reduction (P < 0.05) in the number of corpora lutea and antral and growing follicles, in contrast to an increase (P < 0.05) in atretic follicles in a dose- and time-dependent manner. Remarkable histopathological changes occurred in the ovaries of all ND-treated groups. In conclusion, the different doses of ND caused changes in the estrous cycle and ovarian tissue of rats, and recovery periods (30 and 60 days) were insufficient to completely restore the damage in the animals treated with the highest dose.

Abstract
BACKGROUND The most common drug abuse among athletes is anabolic steroids which lead to the development of cardiovascular diseases and sudden death. Thus, the aim of this study was to evaluate cardiovascular outcomes of anabolic consumption in body building athletes. MATERIALS AND METHODS Totally, 267 male athletes at the range of 20-45 years old with the regular consumption of anabolic steroids for >2 months with at least once weekly. High-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride (TG), and hematocrit (Hct) levels were measured after 10 h of fasting. Data analysis was performed using K2, t-test, ANOVA and correlation coefficient through SPSS 17. RESULTS There was a nonsignificant difference between groups regarding HDL, TG, and total cholesterol. There was a significant decrease in the total and categorized LDL and Hct levels in consumers of anabolic steroid versus nonusers (P = 0.01 and P = 0.041, respectively). Results showed a significant increase in systolic and diastolic blood pressure (SBP and DBP) in anabolic steroid users which associates with duration of abuse (P = 0.02 and P = 0.03, respectively). No significant electrocardiography changes were found within the follow-up period. CONCLUSION Increase in SBP or DBP is a common complication of these drugs which can lead serious vascular disorders. The lower LDL cholesterol level might be due to the higher amounts of lipid consumption in these athletes.

Abstract
BACKGROUND The role erectile dysfunction (ED) coupled with low testosterone levels as early markers of atherosclerosis is not well understood. OBJECTIVES To analyze the relationship between serum testosterone levels with both ED and brachial artery flow-mediated vasodilation (FMD), in a primary prevention sample of men. METHODS We enrolled 802 asymptomatic, intermediate CV risk patients, according to the Framingham Risk Score, aged 40-80 years, who underwent the ultrasound examination of FMD, the evaluation of ED and the assessment of total serum testosterone levels. RESULTS Testosterone levels correlated both with FMD (r = 0.85; p < 0.0001) and IIEF-5 score (rs = 0.65; p < 0.0001). Multivariable logistic regression analyses revealed that lower serum testosterone levels were strongly associated (p < 0.001) with severe (OR 0.78; 95% CI: 0.62-0.86), and moderate ED (OR 0.85; 95% CI: 0.72-0.97), while impaired FMD percentages were strongly associated (p < 0.001) with severe (OR 0.68; 95% CI: 0.59-0.79), moderate (OR 0.76; 95% CI: 0.63-0.83) and mild to moderate ED (OR 0.8; 95% CI: 0.69-0.94). Mild ED resulted statistically associated with lower FMD (OR 0.94; 95% CI: 0.82 - 1.07; p = 0.03) but not with serum testosterone levels. These relations were not substantially affected by adjustments for further potential confounders including smoking status, hypertension, diabetes mellitus and body mass index. CONCLUSIONS lower total serum testosterone levels are associated with impaired FMD and ED in this sample of intermediate CV risk men according to the Framingham Risk Score.

Abstract
PURPOSE Anabolic steroid (AS) misuse is widespread amongst recreational bodybuilders; however, their effects on the cardiovascular system are uncertain. Our aim was to document the impact of AS use on cardiac structure, function and the presence of focal fibrosis using the gold standard cardiovascular magnetic resonance imaging (CMR). METHODS A cross-sectional cohort design was utilised with 21 strength-trained participants who underwent CMR imaging of the heart and speckle-tracking echocardiography. Thirteen participants (30 ± 5 years) taking AS for at least 2 years and currently on a "using"-cycle were compared with age and training-matched controls (n = 8; 29 ± 6 years) who self-reported never having taken AS (NAS). RESULTS AS users had higher absolute left ventricular (LV) mass (220 ± 45 g) compared to NAS (163 ± 27 g; p < 0.05) but this difference was removed when indexed to fat-free mass. AS had a reduced right ventricular (RV) ejection fraction (AS 51 ± 4 % vs. NAS 59 ± 5 %; p < 0.05) and a significantly lower left ventricular E':A' myocardial tissue velocity ratio [AS 0.99(0.54) vs. NAS 1.78(0.46) p < 0.05] predominantly due to greater tissue velocities with atrial contraction. Peak LV longitudinal strain was lower in AS users (AS -14.2 ± 2.7 % vs. NAS -16.6 ± 1.9 %; p < 0.05). There was no evidence of focal fibrosis in any participant. CONCLUSIONS AS use was associated with significant LV hypertrophy, albeit in-line with greater fat-free mass, reduced LV strain, diastolic function, and reduced RV ejection fraction in male bodybuilders. There was, however, no evidence of focal fibrosis in any AS user.

Abstract
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.

Abstract
AIMS In this study, we investigated the interaction between exercise-induced mitochondrial adaptation of large vessels and the effects of chronic anabolic androgenic steroids (AASs). METHODS AND RESULTS Four groups of Sprague-Dawley rats were studied: (i) sedentary, (ii) sedentary + nandrolone-treated, (iii) aerobic exercise trained, and (iv) trained + nandrolone-treated. Aerobic training increased the levels of aortic endothelial nitric oxide synthase (eNOS) and heme oxygenase-1 (HO-1) in accordance with improved acetylcholine-induced vascular relaxation. These beneficial effects were associated with induction of mitochondrial complexes I and V, increased mitochondrial DNA copy number, and greater expression of transcription factors involved in mitochondrial biogenesis/fusion. We also observed enhanced mitochondrial autophagy pathway activity, including increased conversion of LC3-I to LC3-II and greater expression of beclin1 and autophagy-related protein-7 (ATG7). The levels of thiobarbituric acid-reactive substances and protein carbonyls remained unchanged, whereas significant increases in catalase and mitochondrial manganese superoxide dismutase (MnSOD) levels were observed in the aortas of trained animals, when compared with sedentary controls. Nandrolone increased oxidative stress biomarkers and inhibited exercise-induced increases of eNOS, HO-1, catalase, and MnSOD expression. In addition, it also attenuated elevated peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) and mitofusin-2 expression, and further up-regulated LC3II conversion, beclin1, ATG7, and dynamin-related protein-1 expression. CONCLUSION These results demonstrate that nandrolone attenuates aortic adaptations to exercise by regulating mitochondrial dynamic remodelling, including down-regulation of mitochondrial biogenesis and intensive autophagy.

Abstract
BACKGROUND The use of androgenic anabolic steroids (AAS) may be associated with changes in atherothrombotic markers and endothelial function. The purpose of this study was to compare atherothrombotic markers and endothelial function of AAS users and non-users. DESIGN Cross-sectional study. METHODS Ten athletes who were users of AAS (confirmed by urine analysis) and 12 non-user athletes were evaluated. Body weight, blood pressure, exercise load (hours/week), complete blood count (CBC), platelets, fibrinogen, lipids, high-sensitivity C-reactive protein (hs-CRP), follicle-stimulating hormone, testosterone and estradiol were measured. Endothelium-dependent and independent functions were assessed by brachial artery ultrasound. RESULTS AAS users had higher body mass and blood pressure (p < 0.05). Platelet count was higher whereas HDL-cholesterol was lower in AAS users compared with non-users (p < 0.05). Levels of hs-CRP were higher in AAS users (p < 0.001). Follicle-stimulating hormone was suppressed in all users and not suppressed in non-users (p < 0.001). Compared with non-users, flow-mediated dilation was significantly reduced in AAS users (p = 0.03), whereas endothelium-independent function was similar in both groups. Additionally, flow-mediated dilation was positively associated with levels of HDL- cholesterol (r = 0.49, p = 0.03). CONCLUSIONS AAS users present important changes in blood lipids as well as in inflammatory markers, which are compatible with increased cardiovascular risk. Furthermore, this profile is accompanied by a reduction in the endothelial function.

Abstract
Objective—
Because population-based data are lacking, we assessed the cross-sectional association between serum testosterone levels and endothelial function, as measured by flow-mediated dilation (FMD) and nitroglycerin-mediated dilation (NMD) of the brachial artery, in men from the population-based Study of Health in Pomerania.
Methods and Results—
Personal characteristics, including major cardiovascular confounders, were collected in 722 men, aged 25 to 85 years. Serum total testosterone and sexual hormone-binding globulin (SHBG) levels were determined by chemiluminescence immunoassays. Free testosterone levels were calculated according to the law of mass action. FMD and NMD measurements were performed using standardized ultrasound techniques. FMD and NMD values below the 20th percentile were considered decreased. Multivariable logistic regression analyses revealed an association for each decrement of total testosterone standard deviation (6.0 nmol/L) with decreased FMD after adjustment for potential confounders (odds ratio 1.30, 95% confidence interval 1.04–1.63;
P
=0.023). Multiple adjusted findings for free testosterone were similar (odds ratio 1.37, 95% confidence interval 1.06–1.76;
P
=0.016). There was no such association of SHBG levels with decreased FMD. Neither testosterone nor SHBG levels were significantly associated with decreased NMD.
Conclusion—
Lower serum total and free testosterone levels are associated with impaired endothelial function in this population-based sample of men.

Abstract
The androgen nandrolone decanoate (ND) is known to cause cardiovascular abnormalities, such as attenuation of the Bezold–Jarisch Reflex (BJR), cardiac hypertrophy, and elevation of mean arterial pressure (MAP). Futhermore, a relationship between androgens and the renin–angiotensin system (RAS) has been reported. The purpose of this study was to evaluate the influence of RAS on the BJR, cardiac and prostatic hypertrophy, and MAP evoked by ND. For this, male Wistar rats were treated with ND (10 mg·(kg body mass)–1 for 8 weeks; DECA), or vehicle (control animals; CON), or enalapril (10 mg·(kg body mass)–1, daily; CONE), or ND and enalapril (10 mg ND + 10 mg enalapril per kilogram of body mass; DECAE). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotensive responses that were elicited by serotonin administration (2–32 µg·(kg body mass)–1). MAP was assessed; cardiac and prostate hypertrophy were determined by the ratio of the tissue mass:body mass, and by histological analysis of the heart. Animals from the DECA group showed prostatic and cardiac hypertrophy, elevation in mean arterial pressure, and an impairment of BJR. Co-treatment with enalapril inhibited these changes. The data from the present study suggest that RAS has an impact on BJR attenuation, cardiac and prostatic hypertrophy, and the elevation in MAP evoked by ND.

Abstract
Androgenic anabolic steroid, physical exercise and stress induce cardiovascular adaptations including increased endothelial function. The present study investigated the effects of these conditions alone and in combination on the vascular responses of male Wistar rats. Exercise was started at 8 weeks of life (60-min swimming sessions 5 days per week for 8 weeks, while carrying a 5% body-weight load). One group received nandrolone (5 mg/kg, twice per week for 8 weeks, im). Acute immobilization stress (2 h) was induced immediately before the experimental protocol. Curves for noradrenaline were obtained for thoracic aorta, with and without endothelium from sedentary and trained rats, submitted or not to stress, treated or not with nandrolone. None of the procedures altered the vascular reactivity to noradrenaline in denuded aorta. In intact aorta, stress and exercise produced vascular adaptive responses characterized by endothelium-dependent hyporeactivity to noradrenaline. These conditions in combination did not potentiate the vascular adaptive response. Exercise-induced vascular adaptive response was abolished by nandrolone. In contrast, the aortal reactivity to noradrenaline of sedentary rats and the vascular adaptive response to stress of sedentary and trained rats were not affected by nandrolone. Maximum response for 7-10 rats/group (g): sedentary 3.8 ± 0.2 vs trained 3.0 ± 0.2*; sedentary/stress 2.7 ± 0.2 vs trained/stress 3.1 ± 0.1*; sedentary/nandrolone 3.6 ± 0.1 vs trained/nandrolone 3.8 ± 0.1; sedentary/stress/nandrolone 3.2 ± 0.1 vs trained/stress/nandrolone 2.5 ± 0.1*; *P < 0.05 compared to its respective control. Stress and physical exercise determine similar vascular adaptive response involving distinct mechanisms as indicated by the observation that only the physical exercise-induced adaptive response was abolished by nandrolone.

Abstract
Boldenone is an anabolic steroid developed for veterinary use. Recently, it is used by bodybuilders in both off-season and pre-contest, where it is well known for increasing vascularity while preparing for a bodybuilding contest. So, the present study was designed to investigate the possible effect of using growth promoter boldenone undecylenate on the rabbit liver tissue. Thirty-two adult New Zealand rabbits were divided into four groups (8 animals each). Control group includes animals that injected intramuscularly with olive oil and dissected after 3 weeks. The experimental groups include animals that receive one, two and three intramuscular injections of 5 mg/kg body weight boldenone, respectively. The animals were dissected after 3, 6 and 9 weeks respectively, where the interval of each dose of boldenon was 3 weeks. Small pieces of the liver tissues were sent for the histopathological examination. Apoptotic p53 and antiapoptotic Bc1-2 proteins were localized immunohistochemically. Histological observations of the liver tissue showed that the sinusoidal congestion was the most prominent feature that extended from the centrilobular to the periportal regions. Hepatocellular vacuolation in the centrilobular region was also detected. Liver immunohistochemical observation showed a significant increase of the apoptotic protein p53 and a significant decrease in the antiapoptotic Bc1-2 proteins. The highest frequency of p53 positive cells was observed in the liver sections of three dose of boldenone injections, while the lowest in control group, also the highest frequency of Bcl-2 positive cells was observed in the liver sections of control group while the lowest in three dose of boldenone injections. The present results investigate that people should be careful if they want to use such steroids to enhance their strength and endurance.

Abstract
Recent surveys and reports suggest that many athletes and bodybuilders abuse anabolic-androgenic steroids (AAS). However, scientific data on the cardiac and metabolic complications of AAS abuse are divergent and often conflicting. A total of 49 studies describing 1,467 athletes were reviewed to investigate the cardiovascular effects of the abuse of AAS. Although studies were typically small and retrospective, some associated AAS abuse with unfavorable effects. Otherwise healthy young athletes abusing AAS may show elevated levels of low-density lipoprotein and low levels of high-density lipoprotein. Although data are conflicting, AAS have also been linked with elevated systolic and diastolic blood pressure and with left ventricular hypertrophy that may persist after AAS cessation. Finally, in small case studies, AAS abuse has been linked with acute myocardial infarction and fatal ventricular arrhythmias. In conclusion, recognition of these adverse effects may improve the education of athletes and increase vigilance when evaluating young athletes with cardiovascular abnormalities.

Abstract
BACKGROUND The chronic consumption of androgenic anabolic steroids (AAS) has shown to cause subclinical impairment of myocardial function. Pulsed-wave Doppler tissue imaging (PWDTI) detects early regional alterations of ventricular function, whereas integrated backscatter cyclic variations (IBScv) are tightly related to the contractile efficiency of the left ventricular wall. The aim of this study was to identify the effects of chronic AAS misuse on myocardial function using both PWDTI and IBScv. METHODS Twenty-eight male bodybuilders (11 AAS users, 17 AAS nonusers) and 20 healthy sedentary subjects (controls), matched according to age, were studied. To assess left ventricular function, each subject underwent standard Doppler echocardiography, PWDTI, and IBScv analyses. RESULTS Left ventricular mass was significantly higher in AAS users than in AAS nonusers and controls. Global systolic function (assessed by determining the ejection fraction) was similar in all subjects, but isovolumetric relaxation time was significantly higher in AAS users than in controls. On PWDTI analysis, AAS users showed regional systolic and diastolic dysfunction (evaluated by measuring s', e', and a') not detectable in the other two groups. IBScv identified regional systolic impairment only in AAS users at the level of the left ventricular inferior wall. CONCLUSIONS The present study confirms that in AAS users, PWDTI and IBScv are effective and reliable noninvasive diagnostic tools for detecting early abnormalities of the systolic and diastolic longitudinal myocardial function, probably related to an increase in myocardial collagen content, interpretable as a repair process against the direct cellular injury produced by AAS.

Abstract
Abuse of anabolic androgenic steroids (AAS) has been linked to a variety of different cardiovascular side effects. In case reports, acute myocardial infarction is the most common event presented, but other adverse cardiovascular effects such as left ventricular hypertrophy, reduced left ventricular function, arterial thrombosis, pulmonary embolism and several cases of sudden cardiac death have also been reported. However, to date there are no prospective, randomized, interventional studies on the long-term cardiovascular effects of abuse of AAS. In this review we have studied the relevant literature regarding several risk factors for cardiovascular disease where the effects of AAS have been scrutinized:(1) Echocardiographic studies show that supraphysiologic doses of AAS lead to both morphologic and functional changes of the heart. These include a tendency to produce myocardial hypertrophy (Fig. 3), a possible increase of heart chamber diameters, unequivocal alterations of diastolic function and ventricular relaxation, and most likely a subclinically compromised left ventricular contractile function. (2) AAS induce a mild, but transient increase of blood pressure. However, the clinical significance of this effect remains modest. (3) Furthermore, AAS confer an enhanced pro-thrombotic state, most prominently through an activation of platelet aggregability. The concomitant effects on the humoral coagulation cascade are more complex and include activation of both pro-coagulatory and fibrinolytic pathways. (4) Users of AAS often demonstrate unfavorable measurements of vascular reactivity involving endothelial-dependent or endothelial-independent vasodilatation. A degree of reversibility seems to be consistent, though. (5) There is a comprehensive body of evidence documenting that AAS induce various alterations of lipid metabolism. The most prominent changes are concomitant elevations of LDL and decreases of HDL, effects that increase the risk of coronary artery disease. And finally, (6) the use of AAS appears to confer an increased risk of life-threatening arrhythmia leading to sudden death, although the underlying mechanisms are still far from being elucidated. Taken together, various lines of evidence involving a variety of pathophysiologic mechanisms suggest an increased risk for cardiovascular disease in users of anabolic androgenic steroids.

Abstract
Anabolic androgenic steroids (AAS) are used by some athletes to enhance performance despite the health risk they may pose in some persons. This work was carried out to evaluate the possible structural and functional alterations in the heart using two-dimensional, M-mode, tissue Doppler imaging (TDI) and strain rate imaging (SRI) in athletes using supraphysiological doses of AAS. Additionally, the histological and ultrastructural changes in cardiac muscles of adult albino rats after injection of sustanon, as an example of AAS, were studied. Fifteen male bodybuilders using anabolic steroids constituted group 1, five male bodybuilders who are not using anabolic steroids constituted group 2, and five nonathletic males constituted negative control group (group 3). They were investigated by two-dimensional, M-mode, TDI and SRI. This study was performed on 30 adult albino rats. They were divided into two groups. Group I (Control group) (10) was subdivided into negative control, subgroup 1a (5), and subgroup 1b (5), which received 0.8 ml olive oil intramuscular once a week for 8 weeks. Group II (Experimental group) (20) received sustanon 10 mg/kg intramuscularly once a week for 8 weeks. The heart specimens were prepared for light microscopy and transmission electron microscopy. Echocardiographic results showed that bodybuilders who use steroids have smaller left ventricular dimension with thicker walls, impaired diastolic function, as well as higher peak systolic strain rate in steroid-using bodybuilders as compared to the other two groups. Light microscopy examination of cardiac muscle fibers showed focal areas of degeneration with loss of striations and vacuolation in the experimental group. Ultrastructural examination showed disturbance of the banding pattern of the cardiac muscle fiber with disintegration, loss of striations, dehiscent intercalated disc, and interrupted Z-bands. Administration of supraphysiological doses of AAS caused severe deleterious effects in the myocardium both in athletes and in experimental animals. The SRI shows promise in the early detection of systolic dysfunction in those athletes who use steroids.

Abstract
Side effects of anabolic steroids with relevance in forensic medicine are mainly due to life-threatening health risks with potential fatal outcome and cases of uncertain limitations of criminal liability after steroid administration. Both problems are typically associated with long-term abuse and excessive overdose of anabolic steroids. Side effects may be due to direct genomic or nongenomic activities (myotrophic, hepatotoxic), can result from down-regulation of endogenous biosynthesis (antiandrogenic) or be indirect consequence of steroid biotransformation (estrogenic).Logically, there are no systematic clinical studies available and the number of causally determined fatalities is fairly limited. The following compilation reviews typical abundant observations in cases where nonnatural deaths (mostly liver failure and sudden cardiac death) were concurrent with steroid abuse. Moreover, frequent associations between structural characteristics and typical side effects are summarized.

Abstract
AIM Female-to-male (FTM) transsexuals are treated with long-term and high-dose androgen. Although androgen is known to affect the cardiovascular system, vascular function in FTM transsexuals has not been fully elucidated. The aim of this study was to evaluate the arterial stiffness in FTM transsexuals treated with androgen. METHODS We evaluated the arterial stiffness in 111 FTM transsexuals (63 untreated FTM transsexuals and 48 FTM transsexuals treated with androgen) using a volume-plethysmographic apparatus equipped with a multi-element applanation tonometry sensor. RESULTS There were no significant differences in age, body mass index and heart rate between the untreated FTM transsexuals and those treated with androgen. The systolic and diastolic blood pressures in FTM transsexuals treated with androgen were significantly higher than those in untreated FTM transsexuals. The level of brachial-ankle pulse wave velocity in FTM transsexuals treated with androgen (1202.8+/-138.2 cm/s) was significantly higher than that in untreated FTM transsexuals (1080.2+/-113.7 cm/s) while there was no significant difference in the carotid augmentation index between untreated FTM transsexuals and those treated with androgen. CONCLUSIONS Long-term and high-dose administration of androgen is likely to cause increased arterial stiffness in FTM transsexuals. To prevent atherosclerosis and cardiovascular events, a periodic checkup and pharmacological therapies for hypertension should be tailored on an individual basis.

Abstract
Anabolic-androgenic steroids (AAS) were the first identified doping agents that have ergogenic effects and are being used to increase muscle mass and strength in adult males. Consequently, athletes are still using them to increase physical performance and bodybuilders are using them to improve size and cosmetic appearance. The prevalence of AAS use has risen dramatically over the last two decades and filtered into all aspects of society. Support for AAS users has increased, but not by the medical profession, who will not accept that AAS use dependency is a psychiatric condition. The adverse effects and potential dangers of AAS use have been well documented. AAS are used in sport by individuals who have acquired knowledge of the half-lives of specific drugs and the dosages and cycles required to avoid detection. Conversely, they are used by bodybuilders in extreme dosages with the intention of gaining muscle mass and size, with little or no regard for the consequences. Polypharmacy by self-prescription is prevalent in this sector. Most recently, AAS use has filtered through to 'recreational street drug' users and is the largest growth of drugs in this subdivision. They are taken to counteract the anorexic and cachectic effects of the illegal psychotropic street drugs. Screening procedures for AAS in World Anti-Doping Agency accredited laboratories are comprehensive and sensitive and are based mainly on gas chromatography-mass spectrometry, although liquid chromatography-mass spectrometry is becoming increasingly more valuable. The use of carbon isotope mass spectrometry is also of increasing importance in the detection of natural androgen administration, particularly to detect testosterone administration. There is a degree of contentiousness in the scenario of AAS drug use, both within and outside sport. AAS and associated doping agents are not illegal per se. Possession is not an offence, despite contravening sporting regulations and moral codes. Until AAS are classified in the same capacity as street drugs in the UK, where possession becomes a criminal offence, they will continue to attract those who want to win at any cost. The knowledge acquired by such work can only assist in the education of individuals who use such doping agents, with a view to minimizing health risks and hopefully once again create a level playing field in sport.

Abstract
Chronic anabolic steroid use suppresses left ventricular functions. However, there is no information regarding the chronic effects of anabolic steroids on right ventricular function which also plays a key role in global cardiac function. The main objective of the present study was to investigate the effects of androgenic anabolic steroids usage among athletes on remodeling the right part of the heart. Androgenic-anabolic steroids-using bodybuilders had smaller diastolic velocities of both ventricles than drug-free bodybuilders and sedentary counterparts. This study shows that androgenic anabolic steroids-using bodybuilders exhibited depressed diastolic functions of both ventricles.

Abstract
Whether providing anticipatory guidance to the young adolescent patient, conducting a preparticipation examination on a young athlete, or treating a sick user of anabolic androgenic steroids (AASs), the primary care physician must be familiar with the adverse consequences of the use of these compounds. This article reviews the endocrine, cardiovascular, neuropsychiatric, musculoskeletal, hematologic, hepatic, and miscellaneous effects of AASs, highlighting effects reported in children and adolescents, and relying on consequences in adults when pediatric data is unavailable.

Abstract
The "win at all costs" mentality fuels athletes to seek performance-enhancing substances, such as anabolic-androgenic steroids, to gain an advantage over their opponents. Nonathletes espouse this same attitude to "win" the battle of attractiveness. An enhanced understanding of anabolic-androgenic steroids and the motivations behind their abuse will arm pediatricians with the ability to engage their patients in a balanced discussion of the benefits and costly risks of anabolic-androgenic steroids and successfully deter further use.

Abstract
BACKGROUND The role of decreasing testosterone levels influencing lipid metabolism in aging men is not well established. METHODS We studied 1619 40 to 69-year old men with andropausal symptoms, who underwent measurements of serum testosterone, triglycerides, total-, and HDL-cholesterol. RESULTS Testosterone (mean 15.25 nmol/l+/-5.43 S.D., range 3.6-45.0 nmol/l) correlated directly with HDL-cholesterol (r=0.24, p<0.0001) and inversely with total cholesterol (r=-0.06, p<0.03), triglycerides (r=-0.30, p<0.0001) and body mass index (r=-0.34, p<0.0001), but not with LDL-cholesterol (r=0.05, p=0.09). In multivariate analyses adjusted for age, body mass index, smoking, alcohol consumption, diabetes and cardiovascular diseases, the significant determinants for serum triglycerides were testosterone (beta=-0.03, p<0.0001), age (beta=-0.01, p<0.0001), body mass index (beta=0.039, p<0.0001) and cardiovascular diseases (beta=0.09, p<0.04). The multivariate correlates of HDL-cholesterol included testosterone (beta=0.007, p<0.0001), body mass index (beta=-0.02, p<0.0001) and alcohol consumption (beta=0.02, p<0.0001). CONCLUSIONS We conclude that in aging men low testosterone levels are associated with a potentially atherogenic lipid profile including high triglycerides and low HDL-cholesterol.

Abstract
BACKGROUND Androgens have striking effects on skeletal muscle, but the effects on human cardiac muscle function are not well defined, neither has the role of metabolic activation (aromatization, 5alpha reduction) of testosterone on cardiac muscle been directly studied. OBJECTIVE To assess the effects of testosterone and nandrolone, a non-amplifiable and non-aromatizable pure androgen, on cardiac muscle function in healthy young men. DESIGN Double-blind, randomized, placebo-controlled, three-arm parallel group clinical trial. SETTING Ambulatory care research centre. PARTICIPANTS Healthy young men randomized into three groups of 10 men. INTERVENTION Weekly intramuscular injections of testosterone (200 mg mixed esters), nandrolone (200 mg nandrolone decanoate) or matching (2 ml arachis oil vehicle) placebo for 4 weeks. MAIN OUTCOME MEASURES Comprehensive measures of cardiac muscle function involving transthoracic cardiac echocardiography measuring myocardial tissue velocity, peak systolic strain and strain rates, and bioimpedance measurement of cardiac output and systematic vascular resistance. RESULTS Left ventricular (LV) function (LV ejection fraction, LV modified TEI index), right ventricular (RV) function (ejection area, tricuspid annular systolic planar motion, RV modified TEI index) as well as cardiac afterload (mean arterial pressure, systemic vascular resistance) and overall cardiac contractility (stroke volume, cardiac output) were within age- and gender-specific reference ranges and were not significantly (P < 0.05) altered by either androgen or placebo over 4 weeks of treatment. Minor changes remaining within normal range were observed solely within the testosterone group for: increased LV end-systolic diameter (30 +/- 7 vs. 33 +/- 5 mm, P = 0.04) and RV end-systolic area (12.8 +/- 1.3 vs. 14.6 +/- 3.3 cm(2), P = 0.04), reduced LV diastolic septal velocity (Em, 9.5 +/- 2.6 vs. 8.7 +/- 2.0 cm/s, P = 0.006), increased LV filling pressure (E/Em ratio, 7.1 +/- 1.6 vs. 8.3 +/- 1.8, P = 0.02) and shortened PR interval on the electrocardiogram (167 +/- 13 vs. 154 +/- 12, P = 0.03). CONCLUSION Four weeks of treatment with testosterone or nandrolone had no beneficial or adverse effects compared with placebo on cardiac function in healthy young men.

Abstract
The aim of this study is to investigate the effects in vitro induced by androgenic anabolic steroids (AAS) (testosterone, nandrolone, androstenedione, norandrostenedione, and norandrostenediol) used illicitly in sport competitions, on the proliferation ability, apoptosis and the intracellular calcium concentration ([Ca2+]i) in human umbilical vein endothelial cells (HUVECs), selected as a prototype of a biological target system whose structure and function can be affected by steroids. For this purpose, we evaluated the proliferation inhibition by cytotoxic assay expressed as the concentration of drug inducing a 50% decrease in growth (IC50). The IC50 was reached for testosterone at 100 microM, androstenedione at 375 microM, nandrolone at 9 microM, norandrostenedione at 500 microM. The IC50 value for norandrostenediol was not reached until a concentration of 6000 microM. The apoptotic effect was evaluated by flow cytometry at IC50 for each drug. We observed that testosterone induced 31% of apoptotic cells, norandrostenedione 25%, androstenedione 15% and nandrolone 18%. We have analyzed the effects of these drugs on [Ca2+]i both in the immediate and long-term continuous presence of each compound. Our data show a statistically significant increase of [Ca2+]i in the acute condition and in long-term treated cultures, suggesting that androgen steroids modulate intracellular levels of calcium independent of incubation time or compound identity. As a whole, this study demonstrates that AAS might alter endothelial homeostasis, predisposing to the early endothelial cell activation that is responsible for vascular complications observed frequently in AAS users.

Abstract
Testosterone is reported to have an acute vasodilating action in vitro, an effect that may impart a favourable haemodynamic response in patients with chronic heart failure. However, the effect of chronic testosterone exposure on general vascular reactivity is poorly described. In the present study, fresh subcutaneous resistance arteries were obtained from patients with heart failure (n=10), healthy controls (n=9) and men with androgen-deficiency (n=17). All arteries were studied using a wire myograph to examine the effect of cumulative additions of testosterone (1 nmol/l–100 μmol/l) compared with vehicle control following maximal pre-constriction with KCl (1–100 μmol/l). The vascular reactivity of arteries from androgen-deficient patients was examined further by recording tension concentration curves to cumulative additions of noradrenaline (1 nmol/l–100 μmol/l) and U46619 (1–300 nmol/l), followed by relaxation concentration curves to additions of ACh (acetylcholine; 10 nmol/l–30 μmol/l) and SNP (sodium nitroprusside; 10 nmol–30 μmol/l) respectively. In all cases, statistical analysis was performed by ANOVA. Patients with proven androgen-deficiency were treated according to clinical recommendations for a minimum of 3 months and further arteries (n=19) were taken for experimentation using the same protocol. In all groups, testosterone was confirmed to be an acute concentration-dependent vasodilator at concentrations ≥1 μmol/l (P=0.0001). The dilating effect of testosterone was augmented in patients with androgen-deficiency prior to treatment, and this effect was abrogated following appropriate testosterone replacement. Testosterone therapy significantly reduced the normal vascular dilating response to ACh and SNP (P<0.01) and significantly increased the contractile response to noradrenaline (P<0.01), but not U46619. Testosterone is an acute dose-dependent vasodilator of resistance arteries. Physiological testosterone replacement attenuates general vascular reactivity in androgen-deficient subjects. The numerous perceived benefits of testosterone replacement may be offset by a decline in vascular reactivity and, therefore, further studies and careful monitoring of patients is recommended.

Abstract
BACKGROUND Anabolic androgenic steroid (AAS) is the familiar name for synthetic derivatives of the male sex hormone, testosterone. A large number of young adults abuse AAS to enhance performance and physical appearance. The aim of this study was to evaluate the effects of AAS abuse on the gingival tissues in a group of bodybuilders and weight lifters. METHODS The test group was composed of 24 athletes aged between 17 and 29 years who had been using AAS for >1 year. All subjects were clinically examined for plaque levels (plaque index), gingival inflammation (gingival index), and gingival enlargement. The results were compared to a control group of 20 bodybuilders who had never used AAS drugs and who matched for age, educational level, and oral habits according to the data obtained from the test group. RESULTS Although there were no statistical differences between the plaque index (P>0.05) and gingival index (P>0.05) scores of the study group and the control group, the AAS abusers had statistically higher scores of gingival thickness, extent of gingival encroachment, and total gingival enlargement scores (P<0.001 each) compared to non-users. CONCLUSIONS The results of this study have revealed that the prolonged use of AAS is closely associated with significant levels of gingival enlargement. Because recreational abuse and abuse in non-competitive sports seem to increase despite legislation, dentists and periodontists should be familiar with the adverse effects of these synthetic derivatives of testosterone on the gingival tissues.

Abstract
BACKGROUND Anabolic androgenic steroids are used by some bodybuilders to enhance performance. While the cardiovascular implications of supraphysiological androgen levels requires further clarification, use is associated with sudden death, left ventricular hypertrophy, thrombo-embolism and cerebro-vascular events. MATERIALS AND METHODS To further understand the effect of androgenic anabolic steroid abuse on vascular function, this study assessed vascular stiffness (pulse-wave analysis) and cardiovascular risk factors in 28 male, bodybuilding subjects, of whom ten were actively receiving anabolic agents (group A; 26.4 +/- 7.2 years) and eight had undergone a 3-month "wash-out" period (group B; 32.1 +/- 7.1 years). The remaining ten bodybuilding subjects (group C; 24.4 +/- 4.4 years) denied any past use of anabolic steroids or other performance enhancing drugs. Comparisons were made with ten sedentary male controls (group D, 29.3 +/- 4.7 years). RESULTS Endothelial independent dilatation in response to glycerol trinitrate was significantly impaired in the group currently using anabolic steroids (group A) compared with the other three groups [A (5.63 +/- 3.24%) versus; B (11.10 +/- 4.91%), C (17.88 +/- 9.2%) and D (14.46 +/- 3.9%), P < 0.0005, respectively], whereas no significant differences in endothelial-dependent dilatation were detected between the groups [A (5.0 +/- 3.0%), B (7.4 +/- 3.4%), C (9.6 +/- 4.5%) and D (8.2 +/- 3.3%), P < 0.059, respectively]. CONCLUSIONS Previous studies described a decline in vascular reactivity occurring in bodybuilding subjects which is independent of anabolic steroid use and may result from smooth muscle hypertrophy with increased vascular stiffness. This study revealed impaired vascular reactivity associated with anabolic agents and that improvement in vascular function may occur following their discontinuation.

Abstract
The use of anabolic-androgenic steroids (AAS) has been linked to acute cardiovascular events in athletes. The purpose of the present study was to investigate the aortic elastic properties in athletes who had been self-administering AAS compared with a group of athletes not using these drugs. Fourteen male bodybuilders using AAS and 27 male wrestlers (non-users) volunteered to the study. All subjects were placed in a mild recumbent position and the ascending aorta was recorded in the two-dimensional guided M-mode tracings. Although the aortic distensibility was found to be reduced in user athletes (2.1+/-1.1 vs. 3.8+/-1.4 cm(2) dyn(-1) 10(-6), p=0.01; 9.3+/-3.7 vs. 5.9+/-2.5, p=0.003, respectively). The results of this study indicate that aortic stiffness is increasing in athletes using AAS.
