Summary
Secondary hyperparathyroidism (SHPT) in chronic kidney disease (CKD) can become resistant to medical treatment. Parathyroid intervention is recommended for advanced SHPT, especially when medical treatments fail or complications arise.
Area of Science:
- Nephrology
- Endocrinology
- Bone Metabolism
Context:
- Secondary hyperparathyroidism (SHPT) is a common complication in chronic kidney disease (CKD).
- Advanced SHPT can lead to resistance to medical therapies.
- Elevated serum parathyroid hormone (PTH), calcium (Ca), and phosphorus (Pi) levels characterize this resistance.
Purpose:
- To define the criteria for advanced SHPT with resistance to medical treatment.
- To highlight the indications for parathyroid intervention in CKD patients.
- To emphasize the importance of timely intervention for improved outcomes.
Summary:
- Resistance to medical treatment in SHPT is suspected with intact PTH > 500 pg/mL or parathyroid gland volume > 0.5 cm³.
- Hypercalcemia and hyperphosphatemia associated with SHPT reduce life expectancy.
- Parathyroid intervention is a viable treatment option for resistant SHPT, even with PTH levels below 500 pg/mL.
Impact:
- Parathyroidectomy is particularly beneficial long-term if more than two parathyroid glands are enlarged.
- Intervention timing depends on SHPT severity and complications.
- Appropriate parathyroid intervention can mitigate the risks associated with advanced SHPT and improve patient prognosis.

00:59The 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...

01:17Hormones 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...

01:21Skeleton 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.
00:51Synthesis 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...

01:28Chronic Kidney Disease III: Interprofessional Care
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
