HGH controversies

Last updated

Controversies regarding the use of human growth hormone (HGH) as treatment method have centered on the claims, products, and businesses related to the use of growth hormone as an anti-aging therapy. Most of these controversies fall into two categories:[ citation needed ]

Contents

  1. Claims of exaggerated, misleading, or unfounded assertions that growth hormone treatment safely and effectively slows or reverses the effects of aging.
  2. The sale of products that fraudulently or misleadingly purport to be growth hormone or to increase the user's own secretion of natural human growth hormone to a beneficial degree.

History

A study was published in The New England Journal of Medicine in 1990 by Rudman et al., which showed fat loss, muscle mass increase and maintenance of healthy skin from the administration of growth hormone in twelve elderly men. [1] Despite the fact the authors at no time claimed that GH had reversed the aging process itself, their results were misinterpreted as indicating that GH is an effective anti-aging agent. [2] [3] [4] This study, and others, has led to organizations such as the controversial American Academy of Anti-Aging Medicine promoting the use of this hormone as an "anti-aging agent". [5]

Additionally, companies selling dietary supplements have websites selling products that claim to be linked to GH in the advertising text, with medical-sounding names described as "HGH Releasers". Typical ingredients include amino acids, minerals, vitamins, and/or herbal extracts, the combination of which are described as causing the body to make more GH with corresponding beneficial effects. In the United States, because these products are marketed as dietary supplements it is illegal for them to contain GH, which is a drug. Also, under United States law, products sold as dietary supplements cannot have claims that the supplement treats or prevents any disease or condition, and the advertising material must contain a statement that the health claims are not approved by the FDA. The FTC and the FDA do enforce the law when they become aware of violations. [6]

As a result of the reactions to the 1990 article and its frequent citation by proponents of HGH as any anti-aging agent, in 2003 the NEJM published two articles that came out strongly and clearly stating that there was insufficient medical and scientific evidence to support use of HGH as anti-aging drug. One article was written by the Journal's then-current editor in chief, Jeffrey M. Drazen, M.D. and was entitled, "Inappropriate Advertising of Dietary Supplements". [7] It focused mostly on the advertising of dietary supplements. The other article was written by the editor-in-chief at the time the 1990 article was published, Mary Lee Vance, M.D., and was entitled, "Can Growth Hormone Prevent Aging?"; it focused more on the medical issues around whether there was sufficient evidence to use HGH as an anti-aging agent. [8]

Research

There has never been an adequately large randomized controlled trial to prove definitively that HGH provides significant anti-aging benefits and that there are no significant adverse drug reactions; there have been many small studies which are described below. [8]

Some scientific articles have demonstrated that HGH supplementation does not significantly increase muscle strength or aerobic exercise capacity in healthy individuals. [9] While it is possible that there are some advantages, such as an increase in lean body mass, it is also evident that benefits are being exaggerated by some for commercial gain and ineffective products are being sold to unsuspecting consumers. [10]

Some recent small clinical studies have shown that low-dose GH treatment for elderly patients with GH deficiency changes the body composition by increasing muscle mass, decreasing fat mass, increasing bone density and muscle strength, improves cardiovascular parameters (i.e. decrease of LDL cholesterol), and affects the quality of life without significant side effects. [11] [12] [13] It must be emphasized that these studies were small—only tens of patients—and the results were therefore stated tentatively; in the words of one of the cited sources: "Clearly more studies are needed before GH replacement for the elderly becomes established. Safety issues will require close scrutiny, but the data available so far are sufficiently positive to undertake large multicentre, placebo-controlled trials, particularly looking at endpoints associated with prevention of frailty and loss of independence." [13]

Side-effects of high doses and long-term use

Some of the side effects reportedly seen in previously healthy mature patients after taking high HGH doses include:

Chronic use of HGH is not well studied. However, in Europe a study called "SAGhE" was undertaken to study these long-term effects of HGH in children. [16] The FDA reviewed the study and other medical literature and found no link between HGH intake and an increased risk of death. [17]

Law

In 1990, the US Congress passed an omnibus crime bill, the Crime Control Act of 1990, that amended the Federal Food, Drug, and Cosmetic Act, that classified anabolic steroids as controlled substances and added a new section [18] which reads:

Prohibited distribution of human growth hormone.

(1) Except as provided in paragraph (2), whoever knowingly distributes, or possesses with intent to distribute, human growth hormone for any use in humans other than the treatment of a disease or other recognized medical condition, where such use has been authorized by the Secretary of Health and Human Services under section 355 of this title and pursuant to the order of a physician, is guilty of an offense punishable by not more than 5 years in prison, such fines as are authorized by title 18, or both.
(2) Whoever commits any offense set forth in paragraph (1) and such offense involves an individual under 18 years of age is punishable by not more than 10 years imprisonment, such fines as are authorized by title 18, or both.
(3) Any conviction for a violation of paragraphs (1) and (2) of this subsection shall be considered a felony violation of the Controlled Substances Act [21 U.S.C. 801 et seq.] for the purposes of forfeiture under section 413 of such Act [21 U.S.C. 853].
(4) As used in this subsection the term “human growth hormone” means somatrem, somatropin, or an analogue of either of them.

(5) The Drug Enforcement Administration is authorized to investigate offenses punishable by this subsection. [19] [20]

This section has been taken by some, most notably [18] [21] the authors of a commentary article published in the Journal of the American Medical Association in 2005, as meaning that prescribing HGH off-label may be considered illegal. "Physicians and other health care professionals should be aware that current law explicitly prohibits the distribution of GH except for clearly and narrowly defined indications. Distribution for other uses, or off-label use, such as for antiaging, age-related conditions, and enhancing athletic performance, are illegal. Although GH is not a schedule III drug, section 303 [333] f(5) of the FDCA clearly provides the Drug Enforcement Administration with the responsibility of enforcing the laws governing human GH. Given the clinical concerns and the legal issues involved, we believe that physicians or other persons who currently market, distribute, or administer GH to their patients for any reason other than the well-defined approved (ie, legal) uses of the drug, should not do so." [22]

The Drug Enforcement Administration of the US Department of Justice considers off-label prescribing of HGH to be illegal, and to be a key path for illicit distribution of HGH. [23] The FDA, as recently as 2012, has issued alerts stating that "FDA-approved HGH can be legally prescribed for a limited number of conditions." [24] The FDA and the Department of Justice have shut down companies and compounding pharmacies that have marketed HGH for off-label purposes – especially for bodybuilding and anti-aging uses. [25] [26] And some articles in the popular press, such as those criticizing the pharmaceutical industry for marketing drugs for off-label use (which is clearly illegal) have made strong statements about whether doctors can prescribe HGH off-label: "Unlike other prescription drugs, HGH may be prescribed only for specific uses. U.S. sales are limited by law to treat a rare growth defect in children and a handful of uncommon conditions like short bowel syndrome or Prader-Willi syndrome, a congenital disease that causes reduced muscle tone and a lack of hormones in sex glands." [27] [28]

At the same time, anti-aging clinics where doctors prescribe, administer, and sell HGH to people are big business. [27] [29] In a 2012 article in Vanity Fair, when asked how HGH prescriptions far exceed the number of adult patients far exceeds the estimates for HGH-deficiency, Dr. Dragos Roman, who leads a team at the FDA that reviews drugs in endocrinology, said "The F.D.A. doesn't regulate off-label uses of H.G.H. Sometimes it's used appropriately. Sometimes it's not." [29]

Growth hormone (GH) or somatotropin, also known as human growth hormone in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. GH also stimulates production of insulin-like growth factor 1 (IGF-1) and increases the concentration of glucose and free fatty acids. It is a type of mitogen which is specific only to the receptors on certain types of cells. GH is a 191-amino acid, single-chain polypeptide that is synthesized, stored and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland.

<span class="mw-page-title-main">Prescription drug</span> Medication legally requiring a medical prescription before it can be dispensed

A prescription drug is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practicing medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug.

<span class="mw-page-title-main">Growth hormone deficiency</span> Medical condition

Growth hormone deficiency (GHD), or human growth hormone deficiency, is a medical condition resulting from not enough growth hormone (GH). Generally the most noticeable symptom is that an individual attains a short height. Newborns may also present low blood sugar or a small penis size. In adults there may be decreased muscle mass, high cholesterol levels, or poor bone density.

Growth hormone therapy refers to the use of growth hormone (GH) as a prescription medication—it is one form of hormone therapy. Growth hormone is a peptide hormone secreted by the pituitary gland that stimulates growth and cell reproduction. In the past, growth hormone was extracted from human pituitary glands. Growth hormone is now produced by recombinant DNA technology and is prescribed for a variety of reasons. GH therapy has been a focus of social and ethical controversies for 50 years.

<span class="mw-page-title-main">Sibutramine</span> Appetite suppressant

Sibutramine, formerly sold under the brand name Meridia among others, is an appetite suppressant which has been discontinued in many countries. It works as a serotonin–norepinephrine reuptake inhibitor similar to a tricyclic antidepressant. Until 2010, it was widely marketed and prescribed as an adjunct in the treatment of obesity along with diet and exercise. It has been associated with increased cardiovascular diseases and strokes and has been withdrawn from the market in 2010 in several countries and regions including Australia, Canada, China, the European Union, Hong Kong, India, Mexico, New Zealand, the Philippines, Thailand, the United Kingdom, and the United States. However, the drug remains available in some countries.

An adverse effect is an undesired harmful effect resulting from a medication or other intervention, such as surgery. An adverse effect may be termed a "side effect", when judged to be secondary to a main or therapeutic effect. The term complication is similar to adverse effect, but the latter is typically used in pharmacological contexts, or when the negative effect is expected or common. If the negative effect results from an unsuitable or incorrect dosage or procedure, this is called a medical error and not an adverse effect. Adverse effects are sometimes referred to as "iatrogenic" because they are generated by a physician/treatment. Some adverse effects occur only when starting, increasing or discontinuing a treatment. Using a drug or other medical intervention which is contraindicated may increase the risk of adverse effects. Adverse effects may cause complications of a disease or procedure and negatively affect its prognosis. They may also lead to non-compliance with a treatment regimen. Adverse effects of medical treatment resulted in 142,000 deaths in 2013 up from 94,000 deaths in 1990 globally.

Off-label use is the use of pharmaceutical drugs for an unapproved indication or in an unapproved age group, dosage, or route of administration. Both prescription drugs and over-the-counter drugs (OTCs) can be used in off-label ways, although most studies of off-label use focus on prescription drugs.

Late-onset hypogonadism (LOH) or testosterone deficiency syndrome (TDS) is a term for a condition in older men characterized by measurably low testosterone levels and clinical symptoms mostly of a sexual nature, including decreased desire for mating, fewer spontaneous erections, and erectile dysfunction. It is the result of a gradual drop in testosterone; a steady decline in testosterone levels of about 1% per year can happen and is well documented in both men and women.

<span class="mw-page-title-main">Prasterone</span> Medical usage of the prasterone compound

Prasterone, also known as dehydroepiandrosterone (DHEA) and sold under the brand name Intrarosa among others, is a medication as well as over-the-counter dietary supplement which is used to correct DHEA deficiency due to adrenal insufficiency or old age, as a component of menopausal hormone therapy, to treat painful sexual intercourse due to vaginal atrophy, and to prepare the cervix for childbirth, among other uses. It is taken by mouth, by application to the skin, in through the vagina, or by injection into muscle.

The American Academy of Anti-Aging Medicine (A4M) is a United States 501(c)(3) nonprofit organization that promotes the field of anti-aging medicine, and the organization trains and certifies physicians in this specialty. As of 2011, approximately 26,000 practitioners had been given A4M certificates. The field of anti-aging medicine is not recognized by established medical organizations, such as the American Board of Medical Specialties (ABMS) and the American Medical Association (AMA). The academy's activities include lobbying and public relations. The A4M was founded in 1993 by osteopathic physicians Robert M. Goldman and Ronald Klatz, and as of 2013 claimed 26,000 members from 120 countries.

Saizen is a commercial preparation of synthetic somatropin used for growth hormone treatment. Manufactured by Merck Serono, Saizen is produced by recombinant DNA technology from a mammalian cell line that was modified by the addition of the human GH gene, resulting in an identical 191-amino acid sequence and structure.

<span class="mw-page-title-main">Laron syndrome</span> Medical condition

Laron syndrome (LS), also known as growth hormone insensitivity or growth hormone receptor deficiency (GHRD), is an autosomal recessive disorder characterized by a lack of insulin-like growth factor 1 production in response to growth hormone. It is usually caused by inherited growth hormone receptor (GHR) mutations.

Mecasermin rinfabate, also known as rhIGF-1/rhIGFBP-3, is a drug consisting of recombinant human insulin-like growth factor 1 (IGF-1) and recombinant human insulin-like growth factor binding protein-3 (IGFBP-3) which is used for the treatment of amyotrophic lateral sclerosis.

<span class="mw-page-title-main">Sermorelin</span> Pharmaceutical drug

Sermorelin acetate, also known as GHRH (1-29), is a peptide analogue of growth hormone-releasing hormone (GHRH) which is used as a diagnostic agent to assess growth hormone (GH) secretion for the purpose of diagnosing growth hormone deficiency. It is a 29-amino acid polypeptide representing the 1–29 fragment from endogenous human GHRH, thought to be the shortest fully functional fragment of GHRH.

Growth hormones in sports refers to the use of growth hormones for athletic enhancement, as opposed to growth hormone treatment for medical therapy. Human Growth Hormone is a prescription medication in the US, meaning that its distribution and use without a prescription is illegal. There is limited evidence that GH doping improves athletic performance, although the perception that it does is common in the sporting community. Potential side effects of long term GH doping could mirror the symptoms found in sufferers of acromegaly, a disease in which the anterior pituitary gland produces excess growth hormone. These symptoms include swelling of the hands and feet, joint pain, fluid retention, and excessive sweating.

Regorafenib, sold under the brand name Stivarga among others, is an oral multi-kinase inhibitor developed by Bayer which targets angiogenic, stromal and oncogenic receptor tyrosine kinase (RTK). Regorafenib shows anti-angiogenic activity due to its dual targeted VEGFR2-TIE2 tyrosine kinase inhibition. Since 2009 it was studied as a potential treatment option in multiple tumor types. By 2015 it had two US approvals for advanced cancers.

The anti-aging movement is a social movement devoted to eliminating or reversing aging, or reducing the effects of it. A substantial portion of the attention of the movement is on the possibilities for life extension, but there is also interest in techniques such as cosmetic surgery which ameliorate the effects of aging rather than delay or defeat it.

Somapacitan, sold under the brand name Sogroya, is a growth hormone medication. Somapacitan is a human growth hormone analog. Somapacitan-beco is produced in Escherichia coli by recombinant DNA technology.

Lonapegsomatropin, sold under the brand name Skytrofa, is a human growth hormone used for the treatment of growth hormone deficiency. Lonapegsomatropin is a prodrug of somatropin.
