Glucocorticosteroids in football: use and misuse
Glucocorticosteroids are widely used in medicine and have shown unchallenged therapeutic potential in several chronic inflammatory and other diseases. They are also widely used in sports medicine for the treatment of conditions such as asthma and acute injuries. In fact, as banned substances, most requests for therapeutic use exemption concern glucocorticosteroids. Nevertheless, their beneficial effect in certain conditions in sports, where inflammation is only a secondary reaction, remains to be validated.
Search of the medical literature published between and using PubMed. The findings clearly point out that, despite the common use of glucocorticosteroids in acute injuries in sports, there is actually limited evidence of the true benefits of such a practice.
Physicians must take the possible adverse effects into consideration. In an athlete with clinically verified asthma, inhalational glucocorticosteroids remain first line therapy. Finally, for the purposes of education and prevention of misuse, it should be stressed that a measurable performance enhancing effect of glucocorticoids could not be proved on the basis of the results of the scientific studies to date.
Glucocorticosteroids are widely used in the management of sports related injuries as well as in the disorders of the musculoskeletal system, such as overuse injuries of muscles and muscle—tendon junctions or insertion tendopathies.
Their use requires a standard therapeutic use exemption TUE. These keywords were matched individually with the following subjects: The same procedure was performed for synonyms, related topics, and subtitles of each category. Relevant articles were selected and analysed keeping in mind the question: When and if at all is the use of glucocorticosteroids justified in football?. Their release is regulated by a feedback mechanism between the hypothalamus corticotropin releasing factor , the anterior lobe of the pituitary gland adrenocorticotropic hormone , and the adrenal cortex cortisol.
The physiological glucocorticosteroids, cortisol and cortisone, are metabolised from cholesterol and have to be distinguished from synthetic derivatives.
With the exception of prednisone and prednisolone, synthetic glucocorticosteroids do not have any mineralocorticoid effects. Moreover, glucocorticosteroids inhibit the degranulation of human basophils histamine release but have no effect on mast cells.
With regard to athletes, the most interesting systemic effect of the glucocorticosteroids is energy production by stimulation of gluconeogenesis and mobilisation of amino acids and fatty acids.
As a consequence, systemic glucocorticosteroids have been misused for decades to enhance performance, and they once belonged to the group of most commonly used doping substances in sports.
Athletes also took them to alleviate pain and reduce tiredness, ignoring the possible adverse effects such as diabetes, myopathy, and growth retardation. Even though it has been the general point of view in sports that adrenocorticotropic hormone ACTH and corticosteroids improve maximal performance, this review of literature could not corroborate this hypothesis. An increase of maximal performance with ACTH was not observed. In the blood glucocorticosteroids are bound to the cortisol binding protein and to albumin.
Stress such as exercise, infection, or surgery may increase cortisol production by up to four times. The concentrations of testosterone and cortisol are negatively related as they are competitive agonists at the receptor level of muscular cells: These glucocorticosteroids are known to have good oral bioavailability.
They are primarily eliminated by hepatic metabolism and the metabolites excreted by the kidney. A detailed knowledge of their metabolic effects is required, as the use of glucocorticosteroids is widespread in clinical practice. The hepatic capacity for gluconeogenesis is increased and catabolic actions on muscle, skin, lymphoid, adipose, and connective tissues are enhanced. Clinicians must think carefully about the benefits versus the inevitable, undesirable risks of extended treatment on an individual basis.
The use of glucocorticosteroid injections in the treatment of orthopaedic injuries is a matter of debate. Twenty six patients still had foot problems one year later. Glucocorticosteroids have been used by athletes to improve their performance since the s, but their use is restricted in professional sports.
Acute tendon injuries, tendon disorders, and tendon pain often occur in athletes. The spontaneous tendon rupture can be seen as the clinical endstage manifestation of the affected tendon and paratendon tissue. Extensive performance compromises the micro and macrovasculature of the tendon, which leads to insufficient blood circulation in the affected area. Hypoxia, inadequate nutrition, and energy metabolism are some of the consequences. Besides this, motion and function are facilitated.
Instead, recent animal studies have shown that dexamethasone causes a dose dependent decrease of tenocyte proliferation and reduction in collagen production by tenocytes cultured in vitro. Moreover, the recruitment of tendon progenitor cells has been shown to be modulated. Systemic administration of glucocorticosteroids in athletes has reduced due to serious adverse effects such as glucose intolerance, 25 Cushing's syndrome, 25 , 26 and osteoporosis.
The rate of complications among athletes who had received a glucocorticosteroid infiltration was about The first part of the review primarily dealt with the usage of glucocorticosteroid injection therapies. The second part of the review focused on complications occurring after glucocorticosteroids injection.
Rupture of the plantar fascia was reported to be the predominant problem There is no conclusive evidence for the efficacy of glucocorticosteroids injections in the treatment of the human musculoskeletal structures. Nichols pointed out that the medical literature leading up to does not present the incidence of complication rates associated with therapeutic use of injected or systemic glucocorticosteroids in the treatment of athletic injuries.
There has been substantial discussion regarding when and if at all oral glucocorticosteroids are indicated for musculoskeletal injury 31 too. Oral glucocorticosteroids are frequently prescribed by sports medicine physicians, although there is no documentation of this practice in the literature.
Harmon and Hawley's study 31 aimed, on the one hand, to report patterns corticosteroid prescribing among primary care sports medicine physicians and, on the other hand, to look for evidence based indications.
Of the physicians who took part in the study, In conclusion, glucocorticosteroids are frequently prescribed in sports medicine although there is little evidence to support their use. Glucocorticosteroids possess pleiotropic effects. Hamstring injuries can lead to a significant loss of playing time for athletes. Levine et al analysed the safety of intramuscular corticosteroid injection in selected, severe hamstring injuries in professional American football players.
Although the main problem with glucocorticosteroid injections around muscle—tendon units is incomplete healing or rupture of the tendon, there were no complications in relation to the injection of glucocorticosteroids. The average time to return to full practice was 7. Lack of a control group limits conclusions about the efficacy of the injection. Levine et al concluded that intramuscular glucocorticosteroid injection hastens players' return to full play and lessens the game and practice time they miss.
This hypothesis needs to be evaluated further as the presented observational study is of limited value. There is insufficient published data concerning Achilles' tendonitis to evaluate the pros and cons of glucocorticosteroid injection. According to Shrier et al glucocorticosteroid infiltration in Achilles' tendonitis did not have an advantage over placebo.
Animal studies emphasise the reduced tendon strength after intratendinous injections. Csizy and Hintermann reported on three cases of Achilles' tendon rupture after local steroid injection for Achilles' tendonitis.
Moreover, necrotic tendon changes were seen during the subsequent operation. In a randomised, double blind, placebo controlled study in athletes with chronic Achilles' and patella tendonitis, ultrasonography increased diagnostic accuracy and optimised the delivery of the peritendinous injection of a long acting glucocorticosteroid.
Moreover, this method can objectively monitor the effect of treatment. With this technique of infiltration, there was stabilisation of the ultrasonographic picture of pathological defects in the Achilles' and patellar tendons.
However, when combined with an early rehabilitation programme consisting of running after a few days, many athletes experienced relapse of symptoms within six months. The response to treatment was determined five days later. Fitness to take part in sport was used as a guide. However, long term differences between injection and physiotherapy were significantly in favour of physiotherapy. Besides, the rate of recurrence in the injection group was the highest. Newcomer et al confirmed these observations to a certain extent.
They showed that patients with lateral epicondylitis of a short duration less than four weeks did not benefit substantially from a glucocorticosteroid injection. They emphasised that a rehabilitation programme should be the first line treatment. With respect to the efficacy of glucocorticosteroids, pain need to be differentiated into acute and chronic pain. During the course of a treadmill running test a visual analogue scale was used to record the degree of pain after every minute.
Ng et al aimed to determine the treatment effect of periradicular infiltration of glucocorticosteroids for chronic radicular pain. The patients were randomised to a single injection with bupivacaine and methylprednisolone or bupivacaine only. Clinical improvement occurred in both groups of patients. The results clearly indicated that there was no statistically significant difference in the outcome measures between the groups at three months.
Thus there were no additional benefits of the glucocorticosteroid treatment. There is evidence of benefit from corticosteroids in acute spinal cord injury.
At six months, patients who had received corticosteroids within eight hours of injury had greater improvement in motor function and sensation to pinprick and touch.
Similarly, there is no published evidence to support the use of corticosteroids in mild traumatic brain injury or concussion. As a result, corticosteroids are not recommended for the routine treatment of brain injury. As already mentioned before, there is no convincing evidence that glucocorticosteroid infiltration alters the progression of osteoarthritis. Decrease in pain and improved functional outcomes following the treatment of osteoarthritis of the knee with these injections has been shown.
Adhesive capsulitis is characterised by pain and tenderness in the shoulder joint. One study found that a local steroid injection group A: The improvement in shoulder range and motion is accentuated by the addition of supervised physiotherapy to glucocorticosteroid infiltration. Asthma and allergic rhinitis are regarded to be synonyms of the same allergic syndrome. These drugs might reduce the morbidity caused by inhaled glucocorticosteroids, although the systemic effects of the latter cannot be avoided in some children who have an increased sensitivity to inhaled glucocorticosteroid treatment.
Any additional performance enhancing advantages from medication to control asthma and EIA have not been proved: However, some athletes may unnecessarily use oral and perhaps parenteral glucocorticosteroids to achieve certain side effects.
Allergic rhinitis may be seasonal, intranasal, or persistent.
