RESUMO

Background and objectives: Anabolic androgenic steroids (AAS) are mainly used for aesthetic and performance-enhancing reasons. Their use is a growing public health problem and concern for society because of their adverse effects. The primary aim of this study was to identify psychiatric and personality disorders and to measure anxiety and depression in AAS users. Materials and Methods: Fifty-six males who actively contacted the Anti-Doping Hot-Line and wished to stop using AAS were included. Structured Clinical Interviews Diagnosis-I and -II were used to diagnose psychiatric and personality disorders. The Brief Scale for Anxiety and Montgomery Asberg Depression Rating Scale (subscales from the Comprehensive Psychopathological Rating Scale) were used to measure changes in anxiety and depression. Structured Clinical Interviews Diagnosis-I and -II were performed at one time point. Anxiety and depression were measured at inclusion and after six months. Urine samples were collected for an analysis of AAS and drugs of abuse. Results: All participants reported some adverse effects that they associated with AAS use. In total, 56% and 52% of the cohort fulfilled the criteria for Structured Clinical Interviews Diagnosis-I and -II diagnoses, respectively. A significantly increased risk of reporting aggressive feelings/behaviors (Odds Ratio (OR) = 4.9; Confidence Interval (CI) 0.99-25, p = 0.04), suicidal thoughts/attempts (OR = 4.6, CI 95; 0.99-21, p = 0.04) and criminality (OR = 6.5, CI 1-39, p = 0.03) was found among individuals with AAS use fulfilling the criteria for personality disorders compared with those without such AAS use. The Brief Scale for Anxiety score decreased from the median of 15 at inclusion to 10 at the follow-up visit six months later (p = 0.01, n = 19). Conclusions: Our findings indicate that among individuals with AAS use, those with a personality disorder report more aggressive behaviors, suicidal thoughts/suicidal attempts, and criminality than those without a personality disorder.

RESUMO

Today's doping tests involving longitudinal monitoring of steroid profiles are difficult in women. Women have more complex hormonal fluctuations than men and commonly take drugs such as hormonal contraceptives that are shown to affect biomarkers used in these doping tests. In this study, we followed six women's urinary steroid profile during one menstrual cycle, including both glucuronides and sulfate conjugated fractions. Additionally, we studied what happens to the steroidal module of the Athlete Biological Passport (ABP) after administration of an emergency contraceptive (levonorgestrel, NorLevo®). The study shows that there are large individual variations in all metabolites included in the ABP and that the administration of emergency contraceptives may lead to suspicious steroid profile findings in the ABP. Urinary epitestosterone concentration increased during the menstrual cycle, leading to a decrease in the testosterone/epitestosterone ratio. The ratios followed in the ABP varied widely throughout the menstrual cycle, the coefficient of variation (CV) ranging from 4 to 99%. There was a 3-fold decrease in epitestosterone 24 h post administration of the emergency contraceptive pill and androsterone, etiocholanolone, and 5ß- androstan-3α,17ß-diol concentrations decreased about 2-fold. When analyzed with the ABP software, one of the six women had an atypical profile after taking the emergency contraceptive. Furthermore, we could not find any alterations in excretion routes (i.e., if the metabolites are excreted as glucuronide or sulfate conjugates) during the menstrual cycle or after administration of emergency contraceptive, indicating no direct effect on phase II enzymes.

RESUMO

BACKGROUND: Doping with anabolic androgenic steroids in sports has now developed to a widespread use of these agents among young people outside the sport. This is of major concern to the society. The purpose of the use is mainly for aesthetic reasons and is seen as a male phenomenon. But use also occurs in women where the knowledge is scarce. Our aim was to identify the pattern of doping agents in eight female cases and compare them with similar data from men. METHODS: Eight female users were recruited through Anti-Doping Hot-Line, a national telephone counseling service on doping issues during the years 1998-2004. The use was confirmed with urine doping analysis at the Doping Laboratory. The characteristic of use, co-use of narcotics/other doping agents, exercise pattern, adverse-side effects, family history and reason to begin was evaluated. RESULTS: The women used on average 1.9 different anabolic androgenic steroids and clenbuterol preparations. Ephedrine and growth hormone were co-used in five and one of the women, respectively. Three women reported co-use of narcotics (cannabis and cocaine). The average duration of anabolic agent use before contacting health care was 58 weeks (range 7-104). Side effects for anabolic androgenic steroids (n = 5) included voice changes, clitoral enlargement, body hair growth, whereas women using clenbuterol (n = 2) reported tachycardia and depression. All women except one had a man in close relationship encouraging them to begin with the doping agents. CONCLUSIONS: The use of doping agents in our eight women was different from that in male users. The women used less doping agents and were more prone to contact the health care, at an earlier stage, probably due to the adverse effects. The co-use with ephedrine, growth hormone and cannabis appeared to be in the same range as in men. This is the first study showing that a man in close relationship may motivate a woman to use anabolic agents.

RESUMO

The use of the anabolic androgenic steroid nandrolone and its prohormones is prohibited in sport. A common route of nandrolone administration is intramuscular injections of a nandrolone ester. Here we have investigated the detection time of nandrolone and 19-norandrosterone and 19-noretiocholanolone metabolites in eleven healthy men after the administration of a 150 mg dose of nandrolone decanoate. The urinary concentrations of nandrolone and the metabolites were monitored by GC-MS/MS for nine months and in some samples the presence of 19-norandrosterone was confirmed by GC/C/IRMS analysis. The participants were genotyped for polymorphisms in PDE7B1 and UGT2B15 genes previously shown to influence the activation and inactivation of nandrolone decanoate. There were large inter-individual variations in the excretion rate of nandrolone and the metabolites, although not related to genetic variations in the UGT2B15 (rs1902023) and PDE7B1 (rs7774640) genes. After the administration, 19-norandrosterone was found at 2-8-fold higher concentrations than 19-noretiocholanolone. We showed that nandrolone doping can be identified 4 and 9 months after the injection of only one single dose in six and three individuals, respectively. We also noted that GC/C/IRMS confirms the presence of exogenous 19-norandrosterone in the urine samples, showing δ13 values around -32 ‰. This was true even in a sample that was not identified as an atypical finding after the GC-MS/MS analysis further showing the power of using GC/C/IRMS in routine anti-doping settings.

RESUMO

The newly implemented Steroid Module of the Athlete Biological Passport has improved doping tests for steroids. A biomarker included in this passport is the urinary testosterone glucuronide to epitestosterone glucuronide (T/E) ratio, a ratio greatly affected by a deletion polymorphism in UGT2B17. Suspect urine doping tests are further analyzed with gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) to determine the origin of the androgen. In this study, we investigated the sensitivity of the steroidal module and the IRMS analysis, in subjects administered with three doses of testosterone enanthate (500, 250, and 125 mg), in relation to the UGT2B17 polymorphism. All subjects carrying the UGT2B17 enzyme reached the traditionally used threshold, a T/E ratio of 4, after all three administered doses, whereas none of the subjects devoid of this enzyme reached a T/E of 4. On the other hand, using the athlete biological passport and IRMS analysis, all three doses could be detected to a high degree of sensitivity. The concentrations of all steroids included in the steroidal module were dose dependently increased, except for epitestosterone which decreased independent of dose. The decrease in epitestosterone was significantly associated with circulatory levels of testosterone post dose (rs =0.60 and p=0.007). In conclusion, these results demonstrate that administration of a single dose of 125-500 mg testosterone enanthate could be detected using the athlete biological passport, together with IRMS. Since IRMS is sensitive to testosterone doping independent of UGT2B17 genotype, also very small changes in the steroidal passport should be investigated with IRMS.

RESUMO

AIMS: To study the effect and time profile of different doses of testosterone enanthate on the blood lipid profile and gonadotropins. EXPERIMENTAL DESIGN: Twenty-five healthy male volunteers aged 27-43 years were given 500 mg, 250 mg, and 125 mg of testosterone enanthate as single intramuscular doses of Testoviron(®) Depot. Luteinizing hormone (LH), follicle-stimulating hormone (FSH), blood lipid profile (total cholesterol, plasma [p-] low-density lipoprotein, p-high-density lipoprotein [HDL], p-apolipoprotein A1 [ApoA1], p-apolipoprotein B, p-triglycerides, p-lipoprotein(a), serum [s-] testosterone, and 25-hydroxyvitamin D3) were analyzed prior to, and 4 and 14 days after dosing. Testosterone and epitestosterone in urine (testosterone/epitestosterone ratio) were analyzed prior to each dose after a washout period of 6-8 weeks. RESULTS AND DISCUSSION: All doses investigated suppressed the LH and FSH concentrations in serum. LH remained suppressed 6 weeks after the 500 mg dose. These results indicate that testosterone has a more profound endocrine effect on the hypothalamic-pituitary-gonadal axis than was previously thought. There was no alteration in 25-hydroxyvitamin D3 levels after testosterone administration compared to baseline levels. The 250 and 500 mg doses induced decreased concentrations of ApoA1 and HDL, whereas the lowest dose (125 mg) did not have any effect on the lipid profile. CONCLUSION: The single doses of testosterone produced a dose-dependent increase in serum testosterone concentrations together with suppression of s-LH and s-FSH. Alterations in ApoA1 and HDL were observed after the two highest single doses. It is possible that long-time abuse of anabolic androgenic steroids will lead to alteration in vitamin D status. Knowledge and understanding of the side effects of anabolic androgenic steroids are important to the treatment and care of abusers of testosterone.

RESUMO

The UDP Glucuronosyl Transferase (UGT) enzymes are important in the pharmacokinetics, and conjugation, of a variety of drugs including non-steroidal anti-inflammatory drugs (NSAIDs) as well as anabolic androgenic steroids (AAS). Testosterone glucuronidation capacity is strongly associated with a deletion polymorphism in the UGT2B17 gene. As the use of high doses of NSAIDs has been observed in athletes there is a risk for a drug-drug interaction that may influence the doping tests for AAS. In vitro studies show inhibitory potential on UGT2B7, 2B15, and 2B17 enzymes by NSAIDs. The aim of this study was to investigate if concomitant use of NSAIDs and a single dose of testosterone enanthate would affect the excretion rate of testosterone and epitestosterone glucuronide (TG and EG) as well as the T/E ratio, thereby affecting the outcome of the testosterone doping test. The study was designed as an open, randomized, cross-over study with subjects being their own control. The 23 male healthy volunteers, with either two, one or no allele (ins/ins, ins/del, or del/del) of the UGT2B17 gene, received the maximum recommended dose of NSAID (Ibuprofen or Diclofenac) for 6 days. On day three, 500 mg of testosterone enanthate was administered. Spot urine samples were collected for 17 days. After a wash-out period of 4 months the volunteers received 500 mg testosterone enanthate only, with subsequent spot urine collection for 14 days. The glucuronides of testosterone and epitestosterone were quantified. NSAIDs did not affect the excretion of TG or EG before the administration of testosterone. The concomitant use of NSAIDs and testosterone slightly increased the TG excretion while the EG excretion was less suppressed compared to testosterone use only. The effects of the NSAIDs on the TG and EG excretion did not differ between the UGT2B17 genotype groups. In conclusion, the outcome of testosterone doping tests does not seem to be affected by the use of NSAIDs.

RESUMO

BACKGROUND: Cholesterol is mainly synthesised in liver and the rate-limiting step is the reduction of 3-hydroxy-3methylglutaryl coenzyme A (HMG-CoA) to mevalonate, a reaction catalysed by HMG-CoA reductase (HMGCR). There is a comprehensive body of evidence documenting that anabolic-androgenic steroids are associated with deleterious alterations of lipid profile. In this study we investigated whether a single dose of testosterone enanthate affects the cholesterol biosynthesis and the expression of HMGCR. METHODS: 39 healthy male volunteers were given 500 mg testosterone enanthate as single intramuscular dose of Testoviron®--Depot. The total cholesterol levels prior to and two days after testosterone administration were analysed. Protein expression of HMGCR in whole blood was investigated by Western blotting. In order to study whether testosterone regulates the mRNA expression of HMGCR, in vitro studies were performed in a human liver cell-line (HepG2). RESULTS: The total cholesterol level was significantly increased 15% two days after the testosterone injection (p = 0.007). This is the first time a perturbation in the lipoprotein profile is observed after only a single dose of testosterone. Moreover, the HMGCR mRNA and protein expression was induced by testosterone in vitro and in vivo, respectively. CONCLUSION: Here we provide a molecular explanation how anabolic androgenic steroids may impact on the cholesterol homeostasis, i.e. via an increase of the HMGCR expression. Increasing knowledge and understanding of AAS induced side-effects is important in order to find measures for treatment and care of these abusers.

RESUMO

AIMS: To study the long-term impact of anabolic androgenic steroid (AAS) abuse on the cholesterol profile, and the potential to suppress endocrine activity in men working out at gym facilities. To study the relation between urinary biomarkers for testosterone and nandrolone abuse and the UGT2B17 genotype and time profile. EXPERIMENTAL DESIGN: Subjects (N = 56) were recruited through Anti-Doping Hot-Line. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), plasma levels of low density lipoprotein (LDL), high density lipoprotein (HDL) and urinary steroid profile were regularly measured for a period of up to one year after cessation of intramuscular AAS abuse. RESULTS AND DISCUSSION: A sustained suppression of LH, and FSH was observed for several months. The nandrolone urinary biomarker 19-NA was detectable several months after the last nandrolone intake and was correlated to the levels of LH and FSH. Testosterone abuse on the other hand was detectable only for a few weeks, and some of the testosterone abusers did not test positive due to a genetic deletion polymorphism of the UGT2B17. Significantly increased levels of HDL and decreased levels of LDL were observed for 6-months after cessation of AAS abuse. CONCLUSION: Some individuals had a sustained suppression of LH and FSH for a period of 1 year whereas the cholesterol profile was normalized within 6 month. The long term consequences of these findings remain to be established.

RESUMO

BACKGROUND: Anabolic-androgenic steroids (AAS) have long been used by body-builders seeking to increase muscle size, strength and beauty. AAS are sometimes used together with narcotic agents and are thought to serve as a gateway to narcotic substance use, but this theory has not yet been substantiated clinically or sociologically. METHODS: Mandatory interviews were carried out with individuals (n=56) suspected of infringement of the narcotic laws in Sweden with confiscated and/or confirmed use of AAS. Data were collected over 12 months. RESULTS: Seventy-three percent of subjects with confirmed use of AAS were also using narcotic substances. The use of AAS was preceded by the use of narcotic agents in 55% of subjects. Only one-fifth of the subjects in the study had used AAS before using narcotic agents. CONCLUSION: Co-use of AAS and narcotics agents is frequent among young people taken into custody for criminal activity and investigated by the police in Sweden. The study does not lend support to the hypothesis that AAS are commonly a gateway drug to narcotic use.

RESUMO

Amyloid-beta (Abeta) with 40 (Abeta40) and 42 (Abeta42) amino acids, the main components of amyloid plaques in the Alzheimer's disease (AD) brain, can be measured in human cerebrospinal fluid (CSF) and plasma. Whereas CSF Abeta42 is decreased in AD, some studies have reported changed plasma Abeta levels in AD and in subjects with mild cognitive impairment (MCI). To this date it is unclear if and how CSF and plasma levels of Abeta correlate with each other in healthy individuals, albeit earlier studies on AD patients found no correlation between CSF and plasma Abeta. We have measured Abeta40 and Abeta42 in paired CSF and plasma samples from patients with AD (n=39), MCI (n=29) and healthy control subjects (n=18). We observed a clear correlation between CSF and plasma levels for both Abeta40 and Abeta42 in healthy individuals, whereas no such correlation could be seen for AD or MCI cases. Similarly to other studies we also found low levels of Abeta42 in AD CSF, whereas there were no significant differences in plasma Abeta levels between the diagnostic groups. Our findings suggest that the normal equilibrium between CSF and plasma Abeta may be disrupted with the initiation of amyloid deposition in the brain.

RESUMO

Inheritance of the apolipoprotein E (APOE) epsilon 4 allele is associated with an increased risk of Alzheimer's disease (AD). However, the risk of AD in APOE epsilon 3/ epsilon 4 heterozygotes is variable. We tested the hypothesis that the risk of AD in APOE epsilon 3/ epsilon 4 heterozygotes was linked to the relative levels of expression of apoE4 versus apoE3 protein. We measured the apoE4 isoform and total apoE using two specific enzyme-linked immunosorbent assay (ELISA) kits in three cohorts of plasma samples and two cohorts of cerebrospinal fluid samples from AD, mild cognitive impairment, and control subjects. The apoE4 ELISAs were specific as they did not detect apoE in APOE epsilon 3/epsilon 3 homozygotes and were comparable to the total apoE ELISAs in APOE epsilon 4/ epsilon 4 homozygotes. In APOE epsilon 3/ epsilon 4 individuals, the ratio of apoE4 to total apoE levels was 30-40% in plasma, suggesting a decreased production or an increased metabolism of apoE4 compared to apoE3. Surprisingly, the ratio in the CSF was reversed, with apoE4 accounting for 60-70% of the total apoE. The proportion of apoE4 in these cases did not vary by diagnosis, age of onset, or duration of AD. We conclude that the proportion of apoE4 in plasma is not predictive of AD risk in APOE epsilon 3/epsilon 4 individuals. However, the greater proportion of apoE4 in the cerebrospinal fluid suggests differential production or metabolism of the protein in the central nervous system (CNS), with the apoE4 isoform dominating.
