Selçuk DaÄdelen1, AyÅegül Atmaca1, Giray Kabakçı2, Tomris ErbaÅ1 1Department of Endocrinology and Metabolism, Hacettepe University, School of Medicine, Ankara, Turkey 2Department of Cardiology, Hacettepe University, School of Medicine, Ankara, Turkey Keywords: Hypogonadism, beta-Thalassemia, heart failure, testosteron enanthate Introduction Heart failure (HF) in beta-thalassemia major (BTM) has previously been attributed almost only to iron-overload [1,2]. However predominantly left-sided HF has been reported to develop in younger and less hemosiderotic BTM patients in contrast to the involvement of elderly and severely hemosiderotic cases by predominantly right-sided HF [3,4]. This is the reason why, Kremastinos et al. emphasized the importance of other risk factors apart from iron-overload in the pathogenesis of HF associated with BTM [5,6]. Androgenic anabolic steroids -including testosteronare known to be associated with hypertension, ventricular remodelling, myocardial ischemia, and sudden cardiac death, even in healthy men who are taking these drugs to in crease athletic performance [7]. Testosteron is the preferred ligand of the human androgen receptor in myocardium, and modulates some cellular actions similar to those seen in HF and cardiomyopathy [7]. In an experimental model, Zaugg et al., have demonstrated for the first time that, androgenic anabolic steroids âincluding testosteron- induced apoptotic cell death in rat myocytes [8]. These findings were regarded as a molecular evidence to understand the underlying pathogenesis of cardiac morbidity and mortality in case of androgenic anabolic steroid abuse [8]. Beyond the heart as an organ to be damaged directly, fluid retention and erythrocytosis are well known side effects of testostesteron therapy which could precipitate pre-existing heart failure [9]. Despite the lack of comparative clinical evidences in human, searching whether the testosteron therapy in physiologic- or supraphysiologic regimens might have different cardiotoxic profiles, it seems reasonable that at least for some instances, testosteron therapy is a potentially cardiotoxic agent depending on host factors. Thus, here we report the first betathalassemic case of the literature, in whom the role of testosteron therapy has been discussed as a contributing factor to the development of HF. Case Presentation A 16-year-old white male with BTM plus secondary hemochromatosis was referred to the endocrinology department due to delayed puberty. Following the physical examination, basal and dynamic hormonal evaluations, and pituitary magnetic resonance imaging, he was diagnosed on hypogonadotropic hypogonadism with pituitary hemochromatosis due to diffuse reduction in pituitary signal intensity on T2-weighed images at a background presence of hepatic hemochromatosis and concomitant high levels of serum ferritin levels. Normal TSH and ACTH responses to TRH and CRH stimulation tests were obtained respectively. GH axis was also evaluated as normal (Table 1). Upon these findings, testosteron replacement therapy âtestosteron enanthate, 50 mg, IM, once in every 3 weeks- was started. Instead of hCG and/or hMG, testosteron was preferred due to patientsâ expectations of a less frequent injection. On the 14th month of testosteron therapy, while he had no cardiovascular sign or symptom, an echocardiography was obtained for routine purposes to screen for probable complications, and suggested diastolic dysfunction with completely normal systolic measurements. Thereafter the dosage of testosteron was increased to 125 mg/month. On the 5th month of dose increment, he admitted to the hospital with palpitation and dyspnea on exertion, and his cardiopulmoner auscultation revealed a systolic murmur over the cardiac base, Gallop rythm and bibasal fine crackles. M-mode, 2-dimensional and Doppler echocardiography was done, reported as the systolic dysfunction of the left ventricle with second degree tricuspid insufficiency, and confirmed the clinical diagnosis of congestive heart failure (Table 2). Despite the compliance with desferrioxamine iron chelation therapy, ferritin was measured as 1550 ng/ml at time of HF-diagnosis. With these findings of heart failure, diuretics, digoxine, angiotension converting enzyme inhibitors plus beta-blockers were administered, and testosteron therapy was stopped. At the 18th month of his follow-ups, congestive heart failure seemed to be stable on therapy with an ejection fraction of 51%. Table 1: Endocrine evaluation of the case before testosteron replacement therapy. Table 2: Echocardiographic findings of the case. Top Introduction Case Presentation Disscussion References Discussion Despite intensive iron-chelation therapy, the survivals of BTM is still limited by the occurrence of heart failure [6]. Myocardial iron deposition alone does not affect left ventricular relaxation but directly causes left ventricular myocardial restriction with an elevation in pulmonary pressure, and thereafter causing predominantly right-sided heart failure [4]. Left ventricular failure, which occurs in younger, less hemosiderotic populations, seems to be multifactorial in etiology [4]. Apart from iron loading, immunogenetic risk factor s are claimed to trigger the mechanisms of left-sided heart failure development in the context of dilated-type cardiomyopathy [4,6]. The clinical presentation of our case shows that there is a temporal association between the initiation of testosteron replacement therapy and HF-development. Interestingly the increase in the dosage of testosteron is also followed by the precipitation of HF. Therefore question of whether the testosteron might have played a triggering role in the development of HF in our case, is raised on. On the contrary, androgens are well known vasodilators in the coronary [10], pulmonary [11], and peripheral vasculature [12]. In fact, it has recently been shown that, testosteron therapy increased the cardiac output acutely in elderly patients with HF via the reduction of left ventricular afterload [13]. Additionally, gonadectomy of adult male rats was shown to reduce the cardiac contractility which was then reversed by gonadal replacement therapy [14]. On the other hand, Gao et al. [15], and Li et al. [16], have reported that testosteron was a cardiomyotoxic agent in the presence of a cardiomyopathic phenotype (beta-2-adrenergic receptor overexpressed and guanylyl cyclase-A knockout mice models, respectively). These controversies regarding the cardio-toxicity, cardio-safety and even the cardiobenefits of testosteron therapy definetly requires further explanations. However it seems reasonable that, the cardiac effects of testosteron in case of an established HF, can be ratherly different than in case of an otherwise normal heart. Consequently we propose that, testesteron replacement therapy could contribute to the development and/or precipitation of HF, especially in predisposed individuals like with BTM-associated hemochromatosis. Regarding the underestimation of such an effect in the literature we suggest that, further clinical evidences are required to document the cardiac effects of gonadal status and gonadal replacement therapies on the HF associated with BTM.

I have been able to use this hypothesis to explain some things. For example, if one has sufficient DHEA and is deficient in testosterone, treatment with testosterone will produce beneficial effects. If one has low DHEA and low testosterone, then supplementation with testosterone may cause problems as the increased testosterone may direct DHEA use for some tissues and, therefore, deprive other tissues of DHEA. I think this may explain why, sometimes, testosterone helps individuals and sometimes produces negative results. In the case you have presented here, beta-thalassemia major, I found one report that found low DHEAS, the precursor of DHEA, to be low (Arch Fr Pediatr. 1993 Oct;50(8):657-63). Therefore, based on my first paragraph, I suggest that supplemental testosterone redirected already low DHEA to rbc production with the result that a reduction in DHEA resulted in heart problems.

From: Ed Friedman on 12 Dec 2006 18:18 Around 50 years ago, doctors studied the effects of testosterone (T) and prostate cancer. Not one patient ever had the level of T in his blood measured. All of the conclusions were based only on the amount of T given. While this might be tolerated for 50 year old work, it is inconceivable that anyone in modern times would have the audacity to publish an article on the effects of giving T without actually measuring the level of T in the blood. Since T is essential in preventing prostate cancer, breast cancer, and Alzheimer's disease, such articles as this are irresponsible. Clearly there was a problem with T and BTM, but no greater condemnation of T can be justified by their data, and without measuring the level of T in the blood, the researchers are clueless as to what actually occurred in their case study.
