A new study published last week and a previous one from the Veterans Administration Hospital System (see below post) show what happens when older men are given testosterone replacement without managing potential blood level increases of factors that can affect their health.

Testosterone replacement can increase red blood cell (and hematocrit which is the total red cell volume) and estradiol production, two important factors for men's health when present in normal levels (red blood cells carry oxygen and estradiol maintains healthy bones, cognitive function and sex drive). However, due to genetic, age or other factors some men can have excessive production of both. High hematocrit and estradiol are more common in older men on testosterone since testosterone related aromatization and erythrocytosis are worse in that population. In excess, both variables have been linked to cardiovascular risks in older men. Not a single one of studies reporting higher cardiovascular risks in men on testosterone have managed either important factor.

Additionally, this latest nonrandomized study states that "No data were available on indications for T prescription, race, laboratory findings, occupational, environmental, or lifestyle factors."

Many clinics are managing hematocrit by recommending blood donation or phlebotomies to men with hematocrit over 53. They are also recommending treatment with low dose anastrozole for men with estradiol over 50 pg/mL. However, an alarming number of medical practices and research studies chose not to follow basic recommendations from the 4 current guideline groups that, in my opinion, may still need revision to add estradiol monitoring. The table below shows a summary of monitoring required by the main 4 guidelines groups in the world.

It is also imperative that future studies at least follow the minimum requirements of the current guidelines. The last few studies that concluded that testosterone may increase cardiovascular risks did not monitor or report hematocrit blood levels. Most guidelines recommend monitoring hematocrit at month 3, 6 and then annually. Are these studies liable for not following minimum guidelines and exposing their volunteers to increased risks?. I do not why I do not see discussions on this alarming fact. Institutional review boards (IRB's) need to educate themselves about this problem so that no more studies are allowed that do not properly monitor men on testosterone replacement. Would a class action lawsuit be required to change this malpractice? Some are already popping up: Testosterone Treatment Lawsuit Information

It is time to revise the current guidelines for testosterone treatment in men to include monitoring and managing estradiol with the same frequency as hematocrit. It is also time to enforce guidelines compliance in all testosterone studies.

I encourage all men currently on testosterone replacement or thinking about starting it to familiarize themselves with the table below and demand that guidelines (along with estradiol monitoring) are followed by their physicians. And, please, do not sign a study consent form if you see that they do not specify the monitoring frequency and side effect management options the researchers are offering.

I also encourage Abbvie (makers of Androgel), Auxillum (makers of Testim), Endo Pharmaceuticals (makers of Fortesta), Lilly (makers of Axiron) to wake up to this fact before they lose millions due to negligent practices that do not follow minimum guidelines.

I am looking forward to the day when a research group will perform a good study that uses a protocol that not only gives testosterone to men but also one that retests them periodically to manage dose, high hematocrit and estradiol blood levels. It should not be a difficult task and it is the only responsible thing to do to come up with conclusions that we can trust.

This is a press release that describes issues with a previous study from the veterans administration hospital that also fails to monitor hematocrit and estradiol (and in which the majority of veterans were not monitored after starting testosterone). When will large medical groups get it?

ExcelMale.com Identifies Major Flaws in Recently Published VA Testosterone Study


A men's health grassroots and education group advocates for better testosterone replacement therapy of veterans of the U.S. Armed Forces


Houston, TX -- (SBWIRE) -- 11/14/2013 -- Last week's Journal of American Medical Association (JAMA) published a retrospective study (1) that was performed at the Veteran's Administration (VA) hospital system. While it has long been known that testosterone replacement therapy (TRT) improves sexual function, bone density, lean body mass, and lipids, this study concluded that testosterone therapy may increase the risk of cardiovascular problems in men with a history of heart disease. It cautioned that men with pre-existing cardiovascular problems and testosterone deficiency should avoid TRT. ExcelMale.com, an education website for men, identified major flaws in this study that wrongly alarmed patients, physicians and the media.

While it is commendable that the VA hospital system collected data on the use of testosterone in over 8,000 veterans with cardiovascular disease, the study highlights deficiencies in the hospital system's testosterone management protocol.

The VA study showed that 40% of patients did not have their testosterone blood levels retested after they started testosterone. This lack of follow up contradicts a review of guidelines published on 2011 by the American College of Cardiology Foundation that The Endocrine Society, the American Association of Clinical Endocrinologists, the American Society of Reproductive Medicine, and the European Association of Urology recommendations of monitoring patients' blood analysis 3 months after initiation of testosterone therapy (2) to determine TRT dose adjustments and potential side effects.

A previously study (3) also published in JAMA in 2009 showed that men with total testosterone blood levels below 550 ng/dl had a significant increase in their risk of cardiovascular disease, while men with levels above 550 ng/dl reduced their risk by 30%. Monitored participants in the VA study were only able to increase their total testosterone blood levels to 332 ng/dl, a value considered sub-optimal by all testosterone treatment medical guidelines.

Another shortcoming of the VA hospital system's TRT protocol highlighted by the study is the lack of monitoring and managing of hematocrit (red cell volume) and estradiol (a female hormone produced in the body from testosterone). TRT can increase hematocrit and estradiol is a minority of men resulting in increased blood viscosity and cardiovascular risks as documented in the previously mentioned 2009 JAMA study (4). Fortunately, both variables can be easily managed if patients are properly monitored.

The majority of participants in the VA study used testosterone patches. Once a popular method of testosterone delivery, testosterone patches are no longer used due to their poor absorption and inconvenience. This is reflected in the VA study where most of the participants continued to have testosterone deficiency and increased cardiovascular risk.

"Publishing flawed studies only increases the current misconceptions surrounding this important therapy and unnecessarily alarms TRT patients and their physicians", said Nelson Vergel, founder of ExcelMale.com. "We encourage patients, physicians and the media to closely examine studies for misleading information that could increase barriers to life saving therapies", added Vergel.

"We urge the VA hospital system to revise their TRT protocol and to follow current testosterone guidelines. We want only the best for the men who have served our country", said Keith Willse, co-founder of ExcelMale.com.

Seems like it's becoming the new media football to kick around.

Did Lyle Alzado come back to life?
 
I have also being seeing the attorney ads for "victims" who had heart attacks while on TRT. Unfortunately our entitled society has been conditioned to blame someone else for their own faults. Not only is the study this misinformation is based upon simply wrong, but more than likely that patients heart attack was caused by their life-style and habits. The poorly monitored TRT only potentiated the already existing risk due to elevated H/H.

People wonder why physicians have to charge so much. Always have to keep an attorney on retainer and be able to defend yourself against fished law-suits. The drug companies already consider legal pay-outs into their margins, and the margins are so large they can afford to pay. Its probably cheaper than actually putting up a fight.

Great to see the experts starting to debunk this information.

^^^ I agree. elevated hematocrit, RBC, hemoglobin and E2 can cause health issue not testosterone, testosterone causes them to elevate and that's why is it important and should be prescribed by the doctor to do a mandatory blood letting or donation. of course its should be based on BW, but there is no harm whatsoever to donate even if you don't need to.

[h=2]Experts, Androgen Study Group petition JAMA to retract testosterone article[/b]
Three medical organizations and an international group of over 130 scientists and physicians have issued a letter to the Journal of the American Medical Association requesting the retraction of an article which associated testosterone therapy with cardiovascular disease.

Associate Clinical Professor of Urology Abraham Morgentaler, MD, of Harvard Medical School, and chairman of the Androgen Study Group said, "To have several professional societies and so many of the most accomplished experts in the field unite in this action indicates the seriousness of the article's errors, and the magnitude of damage this article has caused to the public's perception of testosterone therapy.”

26 Medical Groups Petition to Retract Misleading Testosterone Study

Twenty-Five Medical Societies Join Androgen Study Group to Petition JAMA to Retract Misleading Testosterone Study



In an unprecedented action, twenty-five international medical societies have petitioned the Journal of the American Medical Association to retract the article that precipitated recent concerns regarding cardiovascular risks with testosterone therapy, citing "gross data mismanagement" rendering the study "no longer credible." Twenty-two societies have added their names since the original petition was submitted to JAMA two weeks ago. The article by Rebecca Vigen and colleagues from the University of Colorado, published in the November 13, 2013 issue of JAMA, is entitled "Association of Testosterone Therapy With Mortality, Myocardial Infarction, and Stroke in Men With Low Testosterone Levels." The results were widely reported as new evidence that testosterone therapy is associated with cardiovascular risks, resulting in a Food and Drug Administration safety bulletin issued January 31, 2014.

The 25 medical societies represent US and international groups dedicated to education and research in endocrinology, men's health, andrology, and sexual medicine. These medical societies join more than 160 of the world's leading figures in urology, endocrinology, and andrology from 32 countries, from every continent except Antarctica. Individual signers include 8 emeritus professors, 9 journal editors, and 67 full professors. Societies recommending retraction are:

American Society for Men's Health

Brazilian Society of Endocrinology and Metabolism
Canadian Men's Sexual Health Council
Canadian Society for the Study of Men's Health
European Society for the Study of the Aging Male

The Life Extension Foundation's View on Flawed Testosterone Analysis That Spured Misleading Media Headlines

".... on November 5, 2013, we were startled to see headlines like "Testosterone Treatments Linked to Heart Risks" in the major news media. This headline and others like it were prompted by a retrospective, observational study by Vigen and colleagues published in the September 5, 2013, issue of the Journal of the American Medical Association (JAMA). The study suggests testosterone therapy may increase risk of death and certain cardiovascular events. However, there are several significant shortcomings in the study's design and methodology, and the results conflict with an existing body of research.

Woefully Inadequate Testosterone Replacement

The goal of testosterone restoration in most cases is to restore youthful blood levels of the hormone. Typically, Life Extension® suggests men target a blood level of testosterone between 700 and 900 ng/dL for optimal health.

In studies designed to assess the impact of testosterone replacement therapy, one of the most important considerations is to measure subjects' blood levels of testosterone regularly throughout the study period. This allows the scientists conducting the study to make sure subjects are taking their testosterone as directed and that their blood levels are rising as expected.

Unbelievably, in the flawed analysis by Vigen, only 60% of study subjects receiving testosterone had a follow-up blood test to assess their testosterone levels. Among them, average testosterone levels rose from a very low level of 175.5 ng/dL at baseline to a still far-from-optimal level of 332.2 ng/dL during testosterone therapy.

Raising testosterone levels from a paltry 175.5 ng/dL to only 332.2 ng/dL is unlikely to deliver robust health benefits. In fact, research has shown that restoring testosterone levels to 500 ng/dL or higher is associated with pronounced health benefits, whereas benefits may be less evident at lower levels. "

The impetus for the formation of The Androgen Study Group was the publication of several flawed testosterone trials whose conclusions have already caused unnecessary concern and confusion among healthcare providers and their patients.


With the media attention that testosterone therapy is attracting it is critical that clinical trials are properly conducted and analyzed, and that results are presented in a way that is not misleading.


It is our mission to ensure that the results of research regarding testosterone deficiency and its treatment is presented accurately and fairly within medical literature and to the public.
