    Insights

    Salmon calcitonin treatment in children with osteogenesis imperfecta led to dose-related hypomagnesemia. Metabolic disturbances, including hypomagnesemia, necessitated therapy discontinuation.

    Area of Science:

    • Pediatric Endocrinology
    • Bone Metabolism
    • Pharmacology

    Background:

    • Osteogenesis imperfecta (OI) is a genetic disorder characterized by fragile bones.
    • Salmon calcitonin is a therapeutic agent sometimes used in managing bone diseases.
    • Evaluating the safety and efficacy of salmon calcitonin in pediatric OI cases is crucial.

    Observation:

    • Two pediatric patients with osteogenesis imperfecta received salmon calcitonin treatment.
    • The older child experienced dose-dependent hypomagnesemia during therapy.
    • The younger child developed multiple electrolyte imbalances, including hypomagnesemia, hypophosphatemia, hyponatremia, and hypokalemia.

    Findings:

    • Salmon calcitonin administration was associated with significant metabolic derangements in pediatric patients.
    • Histological examination of rib biopsies showed no beneficial changes after one year of treatment.
    • The observed metabolic consequences outweighed any potential therapeutic benefits.

    Implications:

    • Salmon calcitonin may induce serious electrolyte imbalances in children with osteogenesis imperfecta.
    • Careful monitoring of metabolic parameters is essential during calcitonin therapy in pediatric populations.
    • Alternative treatment strategies for osteogenesis imperfecta should be considered given these adverse effects.

    Bone Disorders

    Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
    Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
    Hormones and Bone Tissue01:17

    Hormones and Bone Tissue

    The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
    Hormones That Influence Osteoblasts and/or Maintain the Matrix
    Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
    Skeleton and Calcium Homeostasis01:21

    Skeleton and Calcium Homeostasis

    Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
    Synthesis and Functions of Calcitonin00:51

    Synthesis and Functions of Calcitonin

    Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
    The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
    The Parathyroid Glands00:59

    The Parathyroid Glands

    The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
    Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...
