Somatostatin The use of cadaver HGH, also known as cadaveric pituitary GH (hGH) or cadaveric growth hormone (c-hGH), represents a significant chapter in the history of medical treatment for growth hormone deficiency. Derived from the pituitary glands of deceased individuals, this form of hGH was the primary source of human growth hormone therapy from its earliest applications in the late 1950s until the mid-1980s. While it offered hope and observable growth for many, particularly children with growth disorders like those treated by Maurice Raben in 1958 for a young dwarf, the extraction process and the nature of the source material ultimately led to serious, and in some cases fatal, complications.

The initial administration of cadaver HGH demonstrated efficacyHuman growth hormone invented | History. Between 1959 and 1985, a substantial number of individuals, including an estimated 1,980 British children, received cadaver-derived human growth hormoneAβ pathology in human growth hormone recipients. In the United States, approximately 7,700 patients were treated with HGH from cadavers. The hormone, scientifically known as human growth hormone (HGH) or somatotropin, is a peptide hormone naturally released by the pituitary gland that stimulates growth and helps maintain normal body structure. Beyond its direct growth-promoting effects, HGH boosts a hormone called insulin-like growth factor-1 (IGF-1), which plays a role in metabolism and works similarly to insulin in regulating blood sugar levels2012年10月18日—Following the discovery of the contamination in 1985, the U.S. Food and Drug Administration halted all distribution ofcadaver-derivedHGH.

However, the reliance on cadaveric sources introduced unforeseen risks. The extraction process, involving pooling pituitary glands from numerous cadavers, inadvertently created a pathway for the transmission of infectious agents, specifically prions. Prions are misfolded proteins that can cause neurodegenerative diseases. This contamination led to the development of iatrogenic Creutzfeldt-Jakob disease (iCJD), a rare and fatal brain disorder. Reports emerged of patients, some with incubation periods as long as 48 years, developing iatrogenic Alzheimer's disease or other neurologic disorders subsequent to cadaver-derived human growth hormone treatment. A notable study in Nature Medicine in 2024 highlighted five cases of Alzheimer's in individuals treated as children with cadaver-derived human growth hormone (c-hGH), and more recently, in 2024, five people appear to have developed Alzheimer's disease after receiving growth hormones from deceased donors' brains as children. The long latency period associated with these conditions meant that the full extent of the risk was not immediately apparentThere is evidence suggesting that procedures used recently to extract and purifyhGHfromcadaverpituitary glands may eliminate experimental contamination by ....

Furthermore, recipients of cadaver-derived human growth hormone have also shown an elevated risk of other severe neurological conditions. Evidence suggests transmission of Alzheimer's and Parkinson's disease through this route, prompting extensive research into evaluation of potential infectivity of Alzheimer and related neurodegenerative prion amyloid pathologies in cadaver human growth hormone recipients. Concerns about mental health have also been raised, with studies indicating that the risk for suicide was slightly elevated among recipients of cadaver-derived human growth hormone (c-hGH) through programs like the National Hormone Pituitary Program (NHPP). Numerous reports have detailed instances of suicide among individuals who received this treatment.

The inherent dangers associated with cadaver HGH became undeniable, leading to a pivotal shift in its production and use. In 1985, the U.S. Food and Drug Administration halted all distribution of cadaver-derived hGH, and shortly thereafter, cadaver-derived hGH was replaced by recombinant growth hormone. This synthetic version, produced in laboratories, effectively eliminated the possibility of prion contamination and has become the standard for HGH therapy, ensuring greater safety for patients.Human Growth Hormone (HGH): Benefits, Risks, and Uses While the era of cadaveric pituitary extracted human growth hormone has concluded from a therapeutic standpoint, the legacy of its use continues to inform medical understanding and underscores the critical importance of rigorous safety protocols in pharmaceutical development.Suicides in National Hormone Pituitary Program Recipients of ... The understanding gained from cadaveric pituitary-derived growth hormone has been instrumental in preventing similar risks with modern medical treatments, albeit with a history that serves as a stark reminder of the potential unintended consequences in early medical interventions.
