DOPING CONTROL IN MALE SOCCER PLAYERS IN BRAZIL: 10 YEARS OF FOLLOW-UP

Objective

To understand the Adverse Analytical Finding (AAF) that have occurred in Brazilian soccer in a recent 10-year period, comparing them to international data, to know the Brazilian profile.

Methods

A review of the AAR in the Doping Control Commission database of the Brazilian Football Association from 2008 to 2017. The AAR in professional male soccer players between 2008 and 2017 were considered.

Results

The sample selected in this research was composed of 40,092 doping tests, with 113 AAR, identified in 18 different competitions (0.28%) in the professional category, in Brazilian national and state competitions between 2008 and 2017, flagged in doping control exams through urine samples. Stimulants were detected most frequently (31.0%), followed by glucocorticoids (21.2%), diuretics, and masking agents (19.5%). The Brazilian Championship series did not show a relationship with any of the World Anti-Doping Agency (WADA) groups of substances. Series A showed 0.07% of AAR, Series B 0.21%, Series C 0.75% and Series D 1.49.

Conclusion

The rate of AAR in Brazilian soccer was 0.28%, lower than the average for all soccer worldwide, and shows similar percentages among field positions. Stimulants were the most prevalent drugs. The national elite soccer competitions showed significantly fewer cases than the lower divisions. Level of Evidence II; Retrospective Study.

Prevalence and Risk Factors Associated with Anabolic-androgenic Steroid Use: A Cross-sectional Study among Gym Users in Riyadh, Saudi Arabia

Objectives

Anabolic-androgenic steroids (AAS) have been used internationally for enhancing physical appearance and performance despite their significant side effects. We sought to identify the prevalence of AAS use and its different risk factors among gym users in Riyadh, Saudi Arabia.

Methods

A cross-sectional survey was distributed among gym users across 20 gyms in Riyadh. The cluster sampling technique was used to represent the four regions of Riyadh (North, South, East, and West). Univariate and multivariate analyses were performed to identify the factors associated with AAS.

Results

Out of 482 participants, 29.3% reported using AAS. The mean age of the study participants was 27.2±6.9 years, 61.0% were single, 67.1% were educated, 35.5% were government employees, and 31.1% were students. The use of AAS was more prevalent among gym members who practiced weightlifting (45.5%), were employed in the private sector (35.8%), and aged > 25 years old (53.3%). Multiple logistic regression showed that the most significant factors associated with the use of AAS among gym members were: weightlifting, using supplementary vitamins or minerals, following special diets, knowing individuals who used AAS, and being offered AAS.

Conclusions

Our study provides clear evidence that the lifetime prevalence of AAS use is high among male gym members in Riyadh with modifiable risk factors. The results could help public health policymakers to take the necessary measures to alleviate the potential negative implications of AAS use at the community level.

[Young athletes and doping in sports]

Young athletes and doping in sports. Prevalence of doping among young athletes (whether children or adolescents) reaches 3 to 5%. In France, this result means that, on average, 240.000 people could be involved. This percentage, which is greater in boys, rises with age and especially with sports involvement (number of hours of sport per week, practicing competitions or at high levels). Looking for performance constitutes the very main determinant of this behaviour. Physicians may contribute to doping prevention through systematic early identification. Some clues, but not pathognomonic, may help, such as low self-esteem, displayed anxiety, easily influenced by peer pressure, strong expectations for results, fear of failure, intention to try expressed by the youth, use of other substances (tobacco, alcohol, cannabis).

Changes in hemoglobin profile reflect autologous blood transfusion misuse in sports

The changes in hemoglobin (Hb) profile following autologous blood transfusion (ABT) for the first time were studied for anti-doping purposes. Twenty-four healthy, trained male subjects (aged 18‒40) were enrolled and randomized into either the transfusion (T) or control (C) groups. Blood samples were taken from the T subjects at baseline, after withdrawal and reinfusion of 450 ml of refrigerated or cryopreserved blood, and from C subjects at the same time points. Hematological variables (Complete blood count, Reticulocytes, Immature Reticulocytes Fraction, Red-cell Distribution Width, OFF-hr score) were measured. The Hb types were analyzed by high-performance liquid chromatography and the Hemoglobin Profile Index (HbPI) arbitrarily calculated. Between-group differences were observed for red blood cells and reticulocytes. Unlike C, the T group, after withdrawal and reinfusion, showed a significant trend analysis for both hematological variables (Hemoglobin concentration, reticulocytes, OFF-hr score) and Hb types (glycated hemoglobin-HbA1c, HbPI). The control charts highlighted samples with abnormal values (> 3-SD above/below the population mean) after reinfusion for hematological variables in one subject versus five subjects for HbA1c and HbPI. A significant ROC-curve analysis (area = 0.649, p = 0.015) identified a HbA1c cut-off value ≤ 2.7% associated to 100% specificity of blood reinfusion (sensitivity 25%). Hemoglobin profile changed in trained subjects after ABT, with abnormal values of HbA1c and HbPI in 42% of subjects after reinfusion. Future studies will confirm the usefulness of these biomarkers in the anti-doping field.

Morphine/Codeine Ratio, a Key in Investigating a Case of Doping

Introduction:

Consumption of codeine can lead to positive urine test for morphine in athletes. Morphine is classified as a prohibited doping drug while Codeine is not. Morphine/codeine ratio is used in forensic medicine to distinguish the consumption of codeine from abuse of morphine and other narcotics.

Case Presentation:

We present an athlete with positive urine test for morphine with a history of consumption of codeine. The disciplinary committee came to conclusion that the athlete had not consumed morphine and did not violate doping code based on morphine/codeine ratio.

Conclusions:

Analysis of codeine to morphine metabolism rate is needed when we are using morphine/codeine ratio to rule out abuse of narcotics. WADA should consider analysis for the CYP2D6 alleles (main metabolizer of codeine) in case of including morphine/codeine ratio in future prohibited list. The possibility of ultra-rapid CYP2D6 cannot be ruled out in certain results of morphine/codeine near the cut point.

Long Term and Intensive Use of Ophthalmic Topical Corticosteroids and the Risk of Positive Doping Test in Athletes: A Case Report

Introduction:

We express the detection of the prohibited substance prednisone, prednisolone in player’s urine sample by long and intensive use eye steroid drops.

Case Presentation:

In a rare case in Iranian football, a player’s urine sample had corticosteroids. After all investigations, it was demonstrated that systemic effects can be induced by using long-term of ophthalmic prednisone.

Conclusions:

It seems to be required to investigate the systemic effects on long term and excessive use of topical corticosteroid drops can have on the result of the sample analysis and showing positive results.

How the Iranian Football Coaches and Players Know About Doping?

Background:

Nowadays, doping is an intricate dilemma. Football is the nationally popular sport in Iran. On the other hand, doping is a serious health hazard sport faces today. Studies dealing with athletes’ knowledge, attitudes and behavior concerning doping in football are scarce.

Objectives:

Therefore, we aimed to investigate the knowledge and attitudes toward doping among the football coaches and players.

Patients and Methods:

In a cross sectional study, 375 participants (239 football players and 136 coaches) were studied. A specially made questionnaire was applied. In this study, football teams of different provinces of the country were selected by randomized clustered sampling and questionnaires were distributed among coaches and players.

Results:

Knowledge of football coaches and players in three categories of doping definitions, recognition of prohibited drugs and side effects of anabolic steroids was poor or moderate in 45.3%, 88.5% and 96.5%, respectively.

Conclusions:

Football players and coaches have poor knowledge about doping in Iran. Moreover, they believe in some inappropriate myths without any scientific or rational basis.It seems necessary to design a comprehensive educational program for all of the athletes and coaches in Iran.

Myocardial scar detected by cardiovascular magnetic resonance in a competitive bodybuilder with longstanding abuse of anabolic steroids

Introduction:

The self-administration intake of anabolic-androgenic steroids (AAS) is a widespread practice in competitive bodybuilders. Structural changes within the myocardium following AAS abuse including hypertrophy, restricted diastolic function as well as systolic dysfunction and impaired ventricular inflow have been reported.

Case Presentation:

We present the case of a 39-year-old bodybuilder with a more than 20-year history of anabolic-androgenic steroids (AAS) abuse presenting with increasing exertional dyspnoea and fatigue. Diagnostic work-up of the patient’s current symptoms included a cine cardiovascular magnetic resonance (CMR). Using a T1-weighted inversion-recovery sequence 10 minutes after application of 0.1 mmol/kg gadolinium with diethylenetriaminepentaacetic acid (gadolinium DTPA), patchy midwall enhancement in the septal and posterolateral region of the left ventricle was demonstrated. This enhancement pattern is different from the enhancement pattern found in patients with ischemic heart disease.

Conclusions:

The present case illustrates for the first time, by CMR, myocardial scarring with severe left ventricular hypertrophy in a patient with normal coronary arteries after long lasting abuse of AAS. With that finding we could demonstrate a link between AAS abuse and the occurrence of myocardial scarring in humans. This finding may help raise awareness of the consequences of AAS use.
