[Parathyroid hormone levels in the aged]

|April 15, 1981
Summary
Serum parathyroid hormone (PTH) levels remain normal in individuals over 65, including those over 75. Age and sex do not significantly alter these essential hormone levels in the elderly population.
Area of Science:
- Endocrinology
- Gerontology
- Biochemistry
Context:
- Age-related changes in endocrine function are common.
- Parathyroid hormone (PTH) plays a crucial role in calcium homeostasis.
- Understanding PTH levels in the elderly is important for clinical assessment.
Purpose:
- To investigate serum parathyroid hormone (PTH) levels in healthy individuals aged 65 and above.
- To determine if age (specifically over 75 years) or sex influences serum PTH levels in this demographic.
Summary:
- A radioimmunoassay utilizing bovine antiserum against COOH terminal fragments of PTH was employed.
- Serum PTH levels were measured in 36 healthy subjects over 65 years of age.
- Results indicated normal serum PTH levels in the elderly, with no significant modifications observed in subgroups (under and over 75 years) or by sex.
Impact:
- Establishes reference ranges for serum PTH in the elderly population.
- Suggests that typical age-related endocrine assessments may not require specific adjustments for PTH in healthy older adults.
- Provides baseline data for future studies on bone metabolism and calcium regulation in aging individuals.
