    This study explored combination therapy for osteoporosis, finding that high-dose growth hormone (hGH) with calcitonin and calcium supplements increased bone mass. Low-dose hGH did not significantly improve skeletal mass in osteoporosis patients.

    Area of Science:

    • Endocrinology
    • Metabolic Bone Diseases
    • Pharmacology

    Background:

    • Osteoporosis is characterized by reduced bone mass and increased fracture risk.
    • Current therapies aim to inhibit bone resorption or stimulate bone formation.
    • Simultaneous stimulation of bone formation and inhibition of resorption offers a potential therapeutic strategy.

    Purpose of the Study:

    • To evaluate the efficacy of combination therapy for increasing skeletal mass in primary osteoporosis.
    • To compare the effects of low-dose versus high-dose human growth hormone (hGH) in combination with salmon calcitonin and calcium supplements.

    Main Methods:

    • A cohort of five patients with primary osteoporosis was treated with calcium supplements and salmon calcitonin.
    • Patients received either a low or a high dose of human growth hormone (hGH).

  • Total body calcium (TB-Ca) was measured using in vivo neutron activation analysis to assess skeletal mass.

    • Main Results:

    • Low-dose hGH therapy did not result in a significant increase in skeletal mass (TB-Ca).
    • High-dose hGH therapy led to an increase in skeletal mass in four out of five patients.
    • One patient in the high-dose group developed secondary hyperparathyroidism.

    Conclusions:

    • Combination therapy, particularly with high-dose hGH, shows potential for increasing skeletal mass in osteoporosis.
    • Further investigation is warranted to optimize dosage and monitor for adverse effects like secondary hyperparathyroidism.
    • This preliminary study suggests that combined anabolic and anti-resorptive treatment may be effective for osteoporosis management.
