Tesamorelin은 추가 트랜스 -3- 헥사 노 산 그룹이 첨가 된 표준 GHRH로 구성된 성장 호르몬 방출 호르몬 (GHRH) 유사체입니다. 캐나다의 TherateChnologies에서 생산 한 Tesamorelin은 2010 년 HIV 관련 지방 복합도에서 사용하기 위해 FDA에 의해 승인 된 최신 약물이되었습니다. 펩티드는 또한 말초 신경 재생을 개선하는 능력과 경미한인지 장애 (MCI), DEMENTIA의 전구체로서 잠재적 인 개입 능력에 대해 조사되었습니다.

Patients suffering from lipodystrophy initially had diet, exercise, and a handful of ineffective medications to rely on for treatment. If those did not work, surgery was a last-ditch, often ineffective, and frequently complicated solution. In 2010, however, the FDA approved tesamorelin specifically for the treatment of HIV-associated lipodystrophy. The drug has been found to reduce adiposity by nearly 20% in this population [1]. Research suggests that tesamorelin is approximately 4 times more effective in reducing adiposity than all of the other available therapies combined ^[2].

Tesamorelin Investigated in Cardiac Disease

People with HIV are at increased risk of developing cardiovascular disease (CVD), in part due to abnormal fat deposition and in part due to the actions of antiretroviral drugs themselves. Prevention of CVD in HIV-positive individuals is considered to be the most important medical intervention for long-term well-being, after highly active antiretroviral therapy (HAART) of course. Until recently, statins have been the cornerstone of medical management in this population.

Research shows that tesamorelin, in addition to decreasing lipodystrophy, also reduces triglyceride levels, total cholesterol levels, and non-HDL-C levels in HIV-positive patients. A 15% reduction in visceral adipose tissue by tesamorelin correlates with a 50 mg decrease in trigylceride levels^{[3], [4]}.

It is worth noting that ectopic fat deposition, as seen in lipodystrophy, is associated with inflammation. Inflammation of any kind is a risk factor for CVD. Visceral adipose tissue, liver fat, and epicardial fat are all independently associated with increased risk of CVD. By reducing ectopic fat deposition, tesamorelin directly decreases inflammation and an individual’s risk for CVD.

Growth Hormone Deficiency and HIV

Recent evidence suggests that HAART is associated with a number of endocrine and metabolic problems, including growth hormone (GH) deficiency. It appears that the pituitary gland is altered in HIV infection and, as a consequence, approximately one third of patients with HIV who are taking HAART have GH deficiency^[5]. This may, to some extent, explain why lipodystrophy is so common in individuals with HIV and also why tesamorelin is such an effective treatment. Tesamorelin is a safer and more effective way to raise GH levels than administration of exogenous GH, particularly in HIV-positive individuals.

Tesamorelin for Peripheral Nerve Damage

Peripheral nerve damage can be a consequence of injury, diabetes, or even surgical interventions. It often results in debilitating problems with both motor and sensory function in the affected area, but there is little that can be done to correct the problem because nerve cells are notoriously difficult to regenerate. Research, however, suggests that therapies based on growth hormone manipulation may improve peripheral nerve injury and increase both rate and extent of healing^[6]. Tesamorelin is currently the leading candidate for such intervention, in part because it already has FDA approval.

Tesamorelin Investigated in Dementia

There is now evidence to suggest that GHRH analogues, like tesamorelin, are effective in enhancing cognition in patients suffering from the early stages of dementia. A large, randomized, double-blind, placebo-controlled study at the University of Washington School of Medicine, carried out over twenty weeks, suggests that tesamorelin and other GHRH analogues may impact dementia by increase gamma-aminobutyric acid (GABA) levels in the brain and by decreasing myo-insoitol (MI) levels^[7]. These findings open up a pathway for using tesamorelin in the treatment of dementia, but also suggest new areas for scientists to explore as they look for a cure or a preventative.

Because it is FDA approved for use in humans, tesamorelin is an attractive peptide for ongoing clinical research. It is currently under review for its ability to reduce cardiovascular disease in HIV, improve healing of peripheral nerves following injury, and slow the progression of dementia. Clinical trials are already underway in several different areas.
