Hypoparathyroidism: causes of development, symptoms, and treatment

Understanding Hypoparathyroidism

Hypoparathyroidism is a rare endocrine disorder characterized by insufficient levels of parathyroid hormone in the body. The condition may arise from dysfunction or removal of the parathyroid glands, leading to disturbances in calcium and phosphorus metabolism in the body. Patients with hypoparathyroidism may experience various symptoms such as seizures, bone and muscle pain, fatigue, and heart rhythm disturbances.

Diagnosis of hypoparathyroidism includes testing for parathyroid hormone levels in the blood, assessing bone density, and other laboratory studies. Treatment of this condition aims to correct calcium and phosphorus metabolism disturbances, as well as to compensate for the deficiency of parathyroid hormone. Regular monitoring and consultations with specialists help control the patients’ condition and prevent possible complications.

Etiology of Hypoparathyroidism

Hypoparathyroidism is a rare endocrine disease caused by insufficient secretion of parathyroid hormone (parathyrin) or decreased sensitivity to this hormone. Various reasons can lead to hypoparathyroidism, including damage to the parathyroid glands during thyroid surgery, autoimmune disorders, gland development abnormalities, hypomagnesemia, hypocalcemia, hereditary factors, and other medical conditions.

Possible causes of hypoparathyroidism can be both acquired and hereditary. Acquired forms may develop due to surgical removal or damage to the parathyroid glands, autoimmune damage to the parathyroids, magnesium or calcium deficiency, as well as other factors affecting the normal function of the parathyroid glands. Hereditary forms of hypoparathyroidism may be due to genetic mutations affecting the synthesis or action of parathyroid hormone.

  • Surgical removal or damage to the parathyroid glands: surgeries on the thyroid gland can damage the parathyroids, which may lead to the development of hypoparathyroidism.
  • Autoimmune disorders: autoimmune diseases can attack the parathyroids, resulting in insufficient production of parathyroid hormone.
  • Hypomagnesemia: magnesium deficiency in the body can reduce parathyroid function and lead to hypoparathyroidism.
  • Hypocalcemia: a lack of calcium can negatively affect parathyroid function, leading to the onset of hypoparathyroidism.
  • Inherited factors: genetic mutations that affect the synthesis or action of parathyroid hormone can lead to hereditary hypoparathyroidism.

Clinical manifestations of hypoparathyroidism

Symptoms of hypoparathyroidism may include tetany seizures, numbness around the mouth and limbs, muscle weakness, arrhythmia, heightened sensitivity to light, bone pain, tooth decay, low blood pressure, and other neurological and somatic manifestations. Skin symptoms such as itching, atopic dermatitis, and blisters may also be associated with hypoparathyroidism.

Signs of hypoparathyroidism can be diverse and manifest in varying degrees of severity. In addition to the general symptoms mentioned, the specifics of the clinical picture may depend on the rate of disease progression, its causes, duration, and the degree of parathyroid function impairment. Given that hypoparathyroidism can lead to serious complications, it is important to timely identify and treat this condition under the supervision of an experienced medical professional.

  • Tetanic cramps, manifesting as muscle spasms, especially in the areas of the face and limbs.
  • Muscle weakness that may lead to difficulties in performing regular physical tasks.
  • Skin manifestations, such as itching, rash, atopic dermatitis, or exacerbation of blistering itch.
  • Pain in bones and skeleton, often accompanied by weakening of bone tissue and increased risk of fractures.
  • Decreased blood pressure, caused by changes in electrolyte balance and cardiovascular reactivity.

Expert opinion on the treatment of hypoparathyroidism

Experts in the field of endocrinology recommend an individualized approach to the treatment of hypoparathyroidism depending on the underlying cause of the disease, the severity of symptoms, the age of the patient, and any accompanying diseases. In most cases, the treatment of hypoparathyroidism includes the intake of vitamin D and calcium to compensate for disturbed mineral metabolism and to support bone tissue.

To date, experts are also exploring the prospects of new treatment methods for hypoparathyroidism, such as the use of bisphosphonates, teriparatide (recombinant parathyroid hormone), and other innovative agents. The effectiveness and safety of these approaches require further clinical research, but they open new horizons in the treatment of this endocrine disease.

Diagnosis of hypoparathyroidism

Diagnosis of hypoparathyroidism includes blood tests for parathyroid hormone (PTH) levels, calcium, phosphorus, and magnesium. Examining bone metabolism indicators, such as alkaline phosphatase and specific markers of bone turnover, can also help confirm the diagnosis. Bone densitometry may be used to assess bone density and identify mineral and densitometric osteopenia, which may be related to hypoparathyroidism.

For differential diagnosis, it is necessary to investigate other possible causes of hypocalcemia, such as vitamin D deficiency, hypomagnesemia, hypothyroidism, and other endocrine disorders. It is important to gather a detailed history, perform a physical examination, and conduct additional tests, including electrocardiography, to comprehensively assess the clinical picture and select the optimal treatment plan.

  • Measurement of parathyroid hormone (PTH) levels: a high level of PTH indicates possible hypoparathyroidism.
  • Calcium level blood test: hypocalcemia is a common sign of hypoparathyroidism.
  • Measurement of phosphorus and magnesium levels in the blood: levels of these elements may also be altered in hypoparathyroidism.
  • Examination of bone metabolism indicators: such as alkaline phosphatase and bone turnover markers, will help assess bone condition.
  • Bone densitometry: used to evaluate bone density and detect osteopenia, which often accompanies hypoparathyroidism.

Treatment of hypoparathyroidism

Treatment of hypoparathyroidism is aimed at correcting calcium and phosphorus levels in the body through the intake of appropriate medications. The goal of therapy is to improve bone health, prevent complications related to hypoparathyroidism, and eliminate clinical manifestations such as muscle cramps and neurological symptoms. Treatment may include taking vitamin D, calcium, and magnesium, as well as using activated vitamin D and parathyroid hormone preparations.

It is important to individualize treatment based on the severity of hypoparathyroidism and the presence of comorbidities. Regular monitoring of bone metabolism markers and hormonal status, as well as regular consultations with an endocrinologist, will help achieve effective control over the disease. In some cases, surgical intervention may be required, especially in the presence of parathyroid tumors.

  • Intake of vitamin D: vitamin D plays a key role in the absorption of calcium and phosphorus in the body, so its intake may be a key component in the treatment of hypoparathyroidism.
  • Intake of calcium and magnesium: calcium and magnesium are essential for maintaining the health of bone tissue and the normal functioning of the nervous system in patients with hypoparathyroidism.
  • Use of activated vitamin D: in some cases, the intake of forms of activated vitamin D may be required to compensate for its deficiency and improve calcium absorption.
  • Parathormone preparations: in some situations, parathormone preparations may be prescribed to improve bone metabolism and manage hormonal imbalance.
  • Individual approach to treatment: treatment of hypoparathyroidism should be tailored individually, taking into account the clinical manifestations, the severity of the disease, and the characteristics of each patient.

Prevention of hypoparathyroidism

Prevention of hypoparathyroidism is directly related to the prevention of its main causes and risk factors. One of the key methods of prevention is maintaining a healthy lifestyle, which includes a balanced diet, sufficient intake of calcium and vitamin D, regular physical activity, and avoiding harmful habits. Additionally, it is important to undergo regular medical check-ups and examinations, especially in the presence of predisposing factors such as thyroid or parathyroid dysfunction, hereditary diseases, or surgical interventions in the area of the thyroid gland.

Effective prevention of hypoparathyroidism also includes timely diagnosis and treatment of other diseases that can lead to the development of this condition, such as vitamin D, magnesium, or calcium deficiency, as well as monitoring the condition of the thyroid gland. Educating patients about the basic mechanisms of hypoparathyroidism development, its symptoms, and diagnostic methods is also an important part of prevention, as it contributes to early detection and prevention of complications of this disease.

  • Moderate intake of calcium and vitamin D: Adhering to the recommended daily intake of calcium and vitamin D can help maintain bone health and prevent hypoparathyroidism.
  • Physical activity: Regular physical exercise promotes strong and healthy bones, which may reduce the risk of developing hypoparathyroidism.
  • Avoiding harmful habits: Alcohol consumption and smoking can negatively affect bone health, increasing the likelihood of developing hypoparathyroidism.
  • Regular medical check-ups: Obvious symptoms or disorders related to parathyroid function can be detected at early stages through systematic medical examinations.
  • Following a diet: A diet rich in calcium and phosphates is important for bone health and the prevention of hypoparathyroidism. Avoiding excess salt also contributes to better bone health.

Unusual aspects of hypoparathyroidism

Hypoparathyroidism, despite its rarity, is a serious endocrine disorder that can significantly impact the quality of life for patients. It is characterized by disturbances in calcium metabolism, which can lead to osteoporosis, muscle cramps, especially at low blood calcium levels. In addition, hypoparathyroidism can cause psychological issues such as depression, anxiety, and mental apathy.

It is important to note that hypoparathyroidism can also be accompanied by unusual manifestations, such as changes in the skin, hair, and nails, as well as an increased susceptibility to infections. Furthermore, hypoparathyroidism can affect the cardiovascular system, causing arrhythmias and other heart problems. Understanding these unusual aspects of the disease can help in timely detection and effective treatment of hypoparathyroidism, minimizing its negative impact on the body.
