NCT02240043

Brief Summary

The aim of this study is to evaluate the growth hormone (GH) and adrenocorticotrophic hormone (ACTH) secretion in elderly without hypothalamic-pituitary disease using the glucagon stimulation test (using Glucagen® Hypokit, Novo Nordisk A/S, Denmark) and evaluate some parameters such as sarcopenia, nutritional state, bone mineral density, frailty criteria with secretion of GH.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Growth Hormone Secretion in the elderly people using glucagon stimulation test (GST)

    up to one week

Secondary Outcomes (1)

  • ACTH release in the elderly people using GST

    up to one week

Other Outcomes (1)

  • Body composition in the elderly people according with GH secretion

    up to 3 months

Study Arms (1)

growth hormone secretion

OTHER

The elderly had common morbidities peculiar to their age, such as systemic arterial hypertension, diabetes mellitus, Parkinson's disease, initial stages of senile dementia, and osteoporosis.

Other: growth hormone secretion

Interventions

The glucagon stimulation test (GST) was performed by intramuscular injection of 1 mg of glucagon (Glucagen® Hypokit, Novo Nordisk A/S, Denmark). The blood samples were collected at baseline and after 90 minutes, 120 minutes, 150 minutes and 180 minutes of glucagon injection for GH and cortisol measurements. The subjects were recumbent during the test, and a cannula was maintained in a vein in the arm or forearm with a saline solution slowly infused to avoid multiple punctures.

Eligibility Criteria

Age65 Years - 95 Years
Sexall
Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • elderly people above 65 years old with comorbidities peculiar to their age (such as hypertension, diabetes, dyslipidemia, parkinson disease) or without comorbidities

You may not qualify if:

  • pituitary disease, severe acute disease, terminal renal chronic disease, active malignant cancer, the presence of any other disease that could interfere with the somatotrophic axis evaluation, and the contraindications for glucagon administration (pheochromocytoma, insulinoma and malnourishment).
