Osteopenia

Osteopenia is a condition characterized by decreased bone mass and deterioration of bone microstructure, which increases the risk of fractures and other osteoporosis-related outcomes. It is not a disease in itself, but is a precursor to osteoporosis and reflects lower bone mineral density (BMD) than normal values. Below BMD thresholds, a variety of adverse effects may occur, including increased bone damage with minor mechanical loads. Osteopenia can occur in both women and men, but is more common in postmenopausal women, especially those with other risk factors such as genetic predisposition or calcium and vitamin D deficiencies.

History of the disease and interesting historical facts

The history of studying diseases related to the skeletal system goes back many centuries and goes back to the ancient Greek and Roman medical and philosophical traditions. The concept of osteopenia as such began to emerge at the intersection of various scientific fields since the 20th century. Scientific research has revealed that bone mass loss can occur without obvious symptoms, which often complicates diagnosis. The first mentions of its manifestations can be found in studies on osteoporosis and metabolic bone disorders conducted in the 1930s and 1940s. With the development of medical technology, such as densitometry, it became possible to assess the level of bone mineral density and understand methods of treatment and prevention. This information paved the way for a deeper understanding of osteopenia and its situation in clinical practice.

Epidemiology

According to the World Health Organization, osteopenia affects millions of people worldwide. In the West, the prevalence of this condition is about 30-40% in women and 10-20% in men over 50 years of age. Research shows that in older men and women, the risk of developing osteopenia increases with age. In high-income countries, osteopenia is observed in about 50% of women over 80 years of age. If we take into account global indicators, a significant increase in the number of osteopenia cases is recorded each year, which is probably due to changes in lifestyle, diet and insufficient physical activity.

Genetic predisposition to this disease

Genetic predisposition to osteopenia plays an important role in its development and includes many genes responsible for bone metabolism. In particular, genes such as COL1A1, VDR and LRP5 are associated with an increased risk of the disease under study. Mutations in these genes can lead to changes in collagen synthesis, impaired calcium transport and low bone strength. These abnormalities can be hereditary, indicating the need for genetic counseling to identify risk in family members. Some studies suggest that genetic factors can account for up to 70% causes of osteopenia, but also include interactions with the environment and lifestyle.

Risk factors for the development of this disease

Risk factors associated with osteopenia can be of various types. These include:

• Nutritional deficiencies - lack of calcium and vitamin D in the daily diet.
• Ignorance of physical condition - a sedentary lifestyle and lack of physical activity.
• Genetic predisposition - a family history of osteopenia.
• Hormonal changes - decreased estrogen levels in postmenopausal women and testosterone levels in men.
• Side effects of medications - Long-term use of glucocorticosteroids and some antidepressants can negatively affect bone health.

Diagnosis of this disease

Diagnosis of osteopenia includes the following main aspects:

• Main symptoms - the disease may not manifest itself for a long time, but when fractures occur, pain in the area of the affected bones and a decrease in strength may be noted.
• Laboratory tests - determination of calcium levels, vitamin D, hormones such as parathyroid hormone.
• Radiological examinations - X-rays to assess structural changes in bones and densitometry to measure mineral density.
• Other types of diagnostics include multispiral computed tomography and magnetic resonance imaging for a more detailed assessment of the condition of bone tissue.
• Differential diagnosis - it is necessary to exclude osteoporosis and other metabolic bone diseases such as osteomalacia and metabolic diseases.

Treatment

Treatment for osteopenia is prescribed depending on the severity of the condition and may include:

• General treatment includes lifestyle changes, including diet and physical activity.
• Pharmacological treatment includes the use of calcium and vitamin D supplements, as well as antiresorptive agents such as bisphosphonates.
• Surgical treatment - in rare cases, surgery may be necessary for complex fractures.
• Other treatments include using special exercises to strengthen bones and physical therapy.

List of medications used to treat this disease

The following groups of drugs are used as an accompaniment to the main treatment of osteopenia:

• Bisphosphonates (eg, risedronate).
• Selective estrogen receptor modulators (eg, ralioxifene).
• Calcium and vitamin D preparations (calcium carbonate, cholecalciferol).
• If necessary, hormone replacement therapy.

Disease monitoring

Monitoring osteopenia requires regular observation and includes:

• Control stages - regular check-ups with a doctor, review and analysis of the effectiveness of the treatment.
• Prognosis - with timely diagnosis and adequate treatment, the prognosis is positive, it is possible to stop or slow down the progression of the disease.
• Complications include the risk of fractures, especially in older people, and possible impairment of quality of life in the case of severe bone damage.

Age-related features of the disease

Osteopenia can progress differently depending on the age group:

• In older people, the disease is more common and leads to more serious consequences due to decreased physical activity and poor nutrition.
• In menopausal women, a sharp decline in estrogen levels increases the risk of developing osteopenia.
• In adolescents and young adults, it may be associated with insufficient physical activity and a diet low in calcium.
