Will testosterone replacement therapy become a new treatment of chronic heart failure? A review based on 8 clinical trials - 0 views

  • TRT could improve significantly the exercise capacity of patients, compared with placebo
  • it could be seen that the effect of TRT on SBP and DBP was controversial
  • in men with congestive heart failure, testosterone reduced the Q-Td, whereas placebo had no effects
  • ...5 more annotations...
  • The MVC and PTmax were significantly improved in TRT patients but remained unchanged in the placebo group
  • handgrip strength improved significantly with testosterone treatment
  • According to EF assessed by echocardiography, no differences were observed between the patients who were prescribed testosterone and those who received placebo
  • There were no differences between the groups in circulating levels of NT pro-BNP, and inflammatory markers were unchanged, except for a decrease in TNF-α from baseline in the placebo group
  • Testosterone supplementation therapy appeared to be safe, and the subjects who accepted testosterone treatment did not appear any obvious adverse reactions.
  •  
    Testosterone therapy in men with CHF found to increase exercise capacity, reduced the Q-T interval in men, improved muscle strength in men, and was found to be safe in meta-analysis.

Effect of Testosterone Replacement Therapy on Cognitive Performance and Depression in Men with Testosterone Deficiency Syndrome - 0 views

  • Azad et al [15] used single photon emission computed tomography and showed that, after 3~5 weeks of TRT, cerebral perfusion was increased in the midbrain and the superior frontal gyrus in seven men with hypogonadism
  • After 12~14 weeks, increased perfusion was still observed in the midbrain as well as in the midcingulate gyrus
  • TDS patients who received TRT showed significant improvement in cognitive function only if mild cognitive impairment was present at baseline
  • ...4 more annotations...
  • Cherrier et al [17] evaluated a sample of 32 subjects, which included 17 men with mild cognitive impairment and 15 with Alzheimer's disease. At the 6-week follow-up, patients who received TRT showed significantly better scores regarding spatial memory, constructional abilities, and verbal memory compared to those noted in the placebo group. Taken together, these results suggest that TRT has a beneficial effect on cognitive function
  • TRT improved mood and well-being, and reduced fatigue and irritability in hypogonadal men
  • The study by Pope et al [20] involved men with depression refractory to standard anti-depressants, and found that TRT lowered the Hamilton Depression score,
  • depression tends to increase as testosterone levels decrease [21], it is highly likely that TRT improved symptoms of depression by increasing testosterone levels.
  •  
    men with Testosterone <300 ng/dl with levels after 8 months of therapy achieving +680 ng/dl.

Effect of Tongkat Ali on stress hormones and psychological mood state in moderately stressed subjects - 0 views

  • At the age of 60, testosterone levels are typically only 40-50% of youthful levels and may be lower
  • Eurycoma contains a group of small peptides referred to as “eurypeptides” that are known to have effects in improving energy status and sex drive in studies of rodents
  • The effects of tongkat ali in restoring normal testosterone levels appears to be less due to actually “stimulating” testosterone synthesis, but rather by increasing the release rate of “free” testosterone from its binding hormone, sex-hormone-binding-globulin (SHBG)
  • ...6 more annotations...
  • The current study found that daily supplementation with tongkat ali root extract (200 mg/day) improves stress hormone profile (lower cortisol; higher testosterone) and certain mood state parameters (lower tension, anger, and confusion)
  • tongkat ali supplementation (100 mg/day) improved lean body mass, 1-RM strength, and arm circumference to a significantly greater degree compared to a placebo group.
  • In a recent 12-week trial [46] of Eurycoma longifolia supplementation (300 mg/day), men (30–55 years of age) showed significant improved compared to placebo in the Physical Functioning domain of the SF-36 quality of life survey
  • sexual libido was increased by 11%
  • In men with low testosterone levels (average age 51 years), one month of daily supplementation with tongkat ali extract (200 mg/day) resulted in a significant improvement in serum testosterone levels and quality-of-life parameters
  • rise in cortisol and drop in testosterone is an early signal of “overtraining”
  •  
    Tongkat Ali, commonly known as long jack, is found to reduce stress and increase Testosterone.  Stress is one of the common causes of low T in men.  It appears that long Jack functions as an adaptogen.

Testosterone Deficiency, Cardiac Health, and Older Men - 0 views

  • Studies have shown pharmacological doses of testosterone to relax coronary arteries when injected intraluminally [39] and to produce modest but consistent improvement in exercise-induced angina and reverse associated ECG changes [40]. The mechanism of action is via blockade of calcium channels with effect of similar magnitude to nifedipine
    • Nathan Goodyear
       
      This directly refutes the recent studies (3) that Testosterone therapy increases cardiovascular events.
    • Nathan Goodyear
       
      Testosterone acts as a calcium channel blocker inducing vasodilation.
  • men with chronic stable angina pectoris, the ischaemic threshold increased after 4 weeks of TRT and a recent study demonstrates improvement continuing beyond 12 months [
  • Exercise capacity in men with chronic heart failure increased after 12 weeks
  • ...36 more annotations...
  • Studies have shown an inverse relationship between serum testosterone and fasting blood glucose and insulin levels
  • Medications such as chronic analgesics, anticonvulsants, 5ARIs, and androgen ablation therapy are associated with increased risk of testosterone deficiency and insulin resistance
  • Women with T2D or metabolic syndrome characteristically have low SHBG and high free testosterone
    • Nathan Goodyear
       
      This stands in polar opposite of that with men.
  • Hypogonadism is a common feature of the metabolic syndrome
  • The precise interaction between insulin resistance, visceral adiposity, and hypogonadism is, as yet, unclear but the important mechanisms are through increased aromatase production, raised leptin levels, and increase in inflammatory kinins
  • levels of testosterone are reduced in proportion to degree of obesity
  • Men should be encouraged to combine aerobic exercise with strength training. As muscle increases, glucose will be burned more efficiently and insulin levels will fall. A minimum of 30 minutes exercise three times weekly should be advised
  • Testosterone increases levels of fast-twitch muscle fibres
  • By increasing testosterone, levels of type 2 fibres increase and glucose burning improves
  • Weight loss will increase levels of testosterone
  • studies now clearly show that low testosterone leads to visceral obesity and metabolic syndrome and is also a consequence of obesity
  • In the case of MMAS [43], a baseline total testosterone of less than 10.4 nmol/L was associated with a greater than 4-fold incidence of type 2 diabetes over the next 9 years
  • There is high level evidence that TRT improves insulin resistance
  • Low testosterone predicts increased mortality and testosterone therapy improves survival in 587 men with type 2 diabetes
  • A similar retrospective US study involved 1031 men with 372 on TRT. The cumulative mortality was 21% in the untreated group versus 10% ( ) in the treated group with the greatest effect in younger men and those with type 2 diabetes
  • the presence of ED has been shown to be an independent risk factor, particularly in hypogonadal men, increasing the risk of cardiac events by over 50%
  • A recent online publication on ischaemic heart disease mortality in men concluded optimal androgen levels are a biomarker for survival
  • inverse associations between low TT or FT (Table 2) and the severity of CAD
  • A recent 10 year study from Western Australia involving 3690 men followed up from 2001–2010 concluded that TT and FT levels in the normal range were associated with decreased all-cause and cardiovascular mortality, for the first time suggesting that both low and DHT are associated with all-cause mortality and higher levels of DHT reduced cardiovascular risk
  • TDS is associated with increased cardiovascular and all-cause mortality
  • The effect of treatment with TRT reduced the mortality rate of treated cohort (8.4%) to that of the eugonadal group whereas the mortality for the untreated remained high at 19.2%
  • hypogonadal men had slightly increased triglycerides and HDL
  • Men with angiographically proven CAD (coronary artery disease) have significantly lower testosterone levels [29] compared to controls ( ) and there was a significant inverse relationship between the degree of CAD and TT (total testosterone) levels
  • TRT has also been shown to reduce fibrinogen to levels similar to fibrates
  • men treated with long acting testosterone showed highly significant reductions in TC, LDL, and triglycerides with increase in HDL, associated with significant reduction in weight, BMI, and visceral fat
  • Low androgen levels are associated with an increase in inflammatory markers
  • A decline was noted in IL6 and TNF-alpha
  • In some studies, a decline in diastolic blood pressure has been observed, after 3–9 months [24, 26] and in systolic blood pressure
  • In the Moscow study, C-reactive protein was reduced by TRT at 30 weeks versus placebo
  • No studies to date show an increase in LUTS/BPH symptoms with higher serum testosterone levels
  • TRT has been shown to upregulate PDE5 [65] and enhance the effect of PDE5Is (now an accepted therapy for both ED and LUTS), it no longer seems logical to advice avoidance of TRT in men with mild to moderate BPH.
    • Nathan Goodyear
       
      What about just starting with normalization of Testosterone levels first.
  • Several meta-analyses have failed to show a link between TRT and development of prostate cancer [66] but some studies have shown a tendency for more aggressive prostate cancer in men with low testosterone
    • Nathan Goodyear
       
      And if one would have looked at their estrogen levels, I guarantee they would have been found to be elevated.
  • low bioavailable testosterone and high SHBG were associated with a 4.9- and 3.2-fold risk of positive biopsy
  • Current EAU, ISSAM, and BSSM guidance [1, 2] is that there is “no evidence TRT is associated with increased risk of prostate cancer or activation of subclinical cancer.”
  • Men with prostate cancer, treated with androgen deprivation, develop an increase of fat mass with an altered lipid profile
  • Erectile dysfunction is an established marker for future cardiovascular risk and the major presenting symptom leading to a diagnosis of low testosterone

Chronic Testosterone Replacement Exerts Cardioprotection against Cardiac Ischemia-Reperfusion Injury by Attenuating Mitochondrial Dysfunction in Testosterone-Deprived Rats - 0 views

  • In this study, the cardioprotective effects of testosterone in testosterone-deprived rats heart with I/R injury were demonstrated
  • Prior to I/R injury, testosterone replacement provided cardioprotective effects in testosterone-deprived rats as indicated by (1) improved cardiac functions by markedly preserved %EF and %FS, and (2) attenuated cardiac sympathovagal imbalance by a markedly decreased LF/HF ratio
  • Testosterone replacement exerts cardioprotective effects by improving left ventricular function and cardiac sympathovagal balance impaired by testosterone deprivation in ORX rats
  • ...3 more annotations...
  • During the I/R period, testosterone replacement in ORX rats exerted the beneficial effects as indicated by (1) improved left ventricular pressure; (2) markedly decreased infarct size; (3) reduced fatal cardiac arrhythmias by increased time to 1st VT/VF onset and reduced arrhythmia scores; and (4) attenuated cardiac mitochondrial dysfunction caused by I/R injury by reducing ROS production, cardiac mitochondrial swelling and mitochondria membrane depolarization.
  • Chronic testosterone replacement also ameliorates left ventricular dysfunction, and reduces the infarct size and cardiac arrhythmias impaired by I/R injury under testosterone-deprived conditions
  • The mechanisms responsible for these beneficial effects of testosterone could be due to its ability to attenuate cardiac mitochondrial dysfunction and cardiomyocyte apoptosis
  •  
    animal study finds that Testosterone therapy is cardioprotective in a preventative mode and with myocardial injury.  Normalization of Testosterone in these animals with low T reduced infant injury size and improved heart function.

Testosterone levels improve in obese men following a common weight-loss operation: Sleeve gastrectomy procedure is beneficial in lowering BMI, raising testosterone levels in obese men, leading to other health benefits -- ScienceDaily - 0 views

  •  
    The ignorance of this authors statements is unmeasurable.  Numerous other studies have shown weight loss in men with obesity is associated with increased Testosterone production.  My book highlights the mechanism by which adipose tissue decreased Testosterone production.  The author was quoted as pointed to no Testosterone replacement (even if levels are low????) despite the evidence that Testosterone will improve glucose metabolism, build muscle (reverse sarcopenia obesity), improve cholesterol metabolism,  and significantly aid Diabetes control just to name a few; yet the author says, give surgery instead.  I am sure the author is a surgeon and thus bias might, just might, be present.

The telomerase activator TA-65 elongates short telomeres and increases health span of adult/old mice without increasing cancer incidence - 0 views

  • studies have demonstrated that the shortest telomeres are causal of reduced cell viability
  • a stable and enforced expression of telomerase leads to an improved health-span, accompanied by an extension of lifespan
  • TA-65 influences the percentage of cellular short telomeres through the activation of telomerase
  • ...17 more annotations...
  • TA-65 administration during 4 months significantly improved the capacity to uptake glucose after a glucose pulse
  • liver protective action of TA-65
  • A disadvantage of mTERT potentiation could be associated to its capacity to favor proliferation of cancerous cells in murine models
  • TA-65 treated mice presented a similar incidence of malignant cancers at time of death, with a tendency to show decreased sarcomas and slightly increased lymphomas
  • We demonstrate here that TA-65 leads to a significant rescue of short telomeres through telomerase activation
  • TA-65 treatment increases proliferation and mobilization potential of mouse keratinocytes in vitro, a situation mimicking telomerase overexpression
  • TAT2, a similar molecule, have beneficial effects in the activation of CD8+ T lymphocytes from HIV-infected patients where they observe an increase of the proliferative potential and enhancement of cytokine/chemokine production
  • TA-65 resulted in a similar rescue of short telomeres in leukocytes post-treatment as observed with humans, most likely through an activation of telomerase
  • we observe that TA-65 lead to 10 fold increase of telomerase RNA levels in the liver of treated mice comparing to the non-treated same-age cohorts
  • TA-65 regulates telomerase at the transcription level, probably through the regulation of the MAPK pathway
  • TA-65 dependent telomerase activation results in a better organ fitness as demonstrated by the improved scores at the glucose tolerance test and insulin levels at fasting
  • TA-65 supplemented mice also present modest enhancement of the subcutaneous and epidermal thickness, as well as higher bone density, representative of an overall fitness status improvemen
  • TA-65 treated mice present higher levels of RBC and hemoglobin comparing to the control cohorts
  • improved health-span of TA-65 treated mice is not accompanied by increased cancer incidence, which may be related to the fact that TERT levels are very modestly increased in all tissues tested except for the liver
  • systemic telomerase overexpression from the germline leads to protection from aging associated pathologies
  • similar situation could be mimicked expressing telomerase late in life in a telomerase deficient background
  • we observed a higher proliferation rate and a partial protection from cell death in some tissues of TA65 treated mice
  •  
    TA-65 shown to increase telomerase activity, and thus telomere length of short telomeres, in mouse study.
