Osteopenia and Osteoporosis

Osteoporosis (osteopenia)

Osteopenia and osteoporosis are two disorders caracterized by bone density loss.


Presentation

Osteopenia has no recognizable symptoms. There is no noticeable pain or change as bone becomes thinner. However, the risk of fractures is increased due to reduced bone density.

Osteoporosis remains asymptomatic until skeletal fragility is announced with a fracture. The clinical evidence of osteoporosis depends on which bones are involved. Thoracic and lumbar vertebral fractures are extremely common and produce loss of height and various deformities; including kyphoscoliosis that can compromise respiratory functions [4]. Pulmonary embolism and pneumonia are common complications of fracture of the femoral neck, pelvis or spine. They cause as many as 50,000 deaths annually.

Rigor

Arm Pain
  • Side effects include heartburn, irritation of the esophagus, nausea, indigestion, leg and arm pain, flu-like symptoms, and fever.[berkeleywellness.com]
Blue Eyes
  • So does being female, having fair skin, red or blond hair, and blue eyes. Genetically, the fair complected have less collagen in their bones. And, those with less body fat or lighter frames have less bone to lose.[trainforeverstrong.com]
Back Pain
  • Bisphosphonates for the prevention and treatment of osteoporosis BMJ 2015 Osteoporosis: now and the future Lancet 2011 52 yo F with Scleroderma, Raynauds, B12 deficiency is seen for chronic back pain.[imreference.com]
  • The following conditions and comorbidities are associated with loss of bone mineral density: - Back pain - Hypertension - Diabetes - Osteoarthritis - RA - COPD - CKD - Asthma - Hyperlipidaemia - Hyperthyroidism - Cushing's syndrome - Pituitary disease[globenewswire.com]
  • Additionally, osteoporotic fractures of the spine can occur simply with the trauma of daily life and can result in postural changes creating severe back pain and changes in appearance such as this woman who suffers from a Dowager’s hump of the upper back[fwcjax.com]
  • But after many years, you may notice signs like back pain, a loss of height, or a stooped posture. For some people, the first sign they have of the disease is a broken bone, usually in the spine or hip.[webmd.com]
Bone Pain
  • Muscle aches & Cramps, Bone pain and Fractures: muscle and bone pain are an indicator of inadequate vitamin D, which is important in bone formation.[livinglovecommunity.com]
  • Another huge advantage is that these patients often have bone pain and joint pain ... which will be relieved almost immediately after a successful parathyroid operation in about 90-95% of patients. Most claim their bone pain is completely gone.[parathyroid.com]
  • Weakening of bone can lead to fracture of bone, pain , and deformity. Osteopenia is an early sign of bone weakening that is less severe than osteoporosis .[emedicinehealth.com]
  • Bone pain, sometimes which is permanent and intense. Loss of height. Hunched or stooped posture. This occurs because the vertebrae, the bones of the spine, can become weaker. Feelings of isolation or depression.[draxe.com]
  • Side effects: Mild gastrointestinal problems (heartburn, acid reflux, irritation of the esophagus, nausea and vomiting) and more serious (ulcers and bleeding) Severe muscle, joint or bone pain Esophageal cancer Breakdown of the jawbone Atypical bone fractures[aarp.org]
Excitement
  • When I was here before, I was so excited about finding out about rebounding rebuilding bones I didn't think to mention turmeric opa.ahsc.arizona.edu/newsro... and kefir draxe.com/kefir-benefits/ and I don't think I have caught up with you anywhere else[healthunlocked.com]
  • Osteoporosis is most common in Caucasian and Asian women, but it is not rare in African-American women and, since dual excitation X-ray absorptiometry (DEXA) has no risk, determining bone density in all perimenopausal women is recommended.[cancertherapyadvisor.com]

Workup

The following investigations are required for the diagnosis of osteoporosis.

  • Serum alkaline phosphatase: Serum alkaline phosphatase is usually normal but may be elevated especially after fracture.
  • Serum calcium and phosphate: The serum levels of calcium and phosphate are normal.
  • Serum parathyroid hormone: Serum parathyroid hormones are normal.
  • X-rays: X-rays show decreased bone mineral density and may reveal one or more fractures (if present). Demineralization is most apparent in the spine and pelvis as well as the femoral head and neck. Compression of the vertebrae may also be seen.
  • Bone densiometry: Bone densiometry is used to determine the density of the spine and hip bones. A score of -2.5 or less is diagnostic of osteoporosis.

Treatment

The treatment plan in osteoporotic diseases is aimed at the prevention of bony fractures and improving lifestyle [6].
There are various options to treat osteoporotic conditions that are given below:

  • Pharmacologic therapy: This approach includes administration of adequate calcium, vitamin D and anti-osteoporotic medication such as bisphosphonates, parathyroid hormone (PTH) and estrogen [7].
  • Vertebroplasty and kyphoplasty: These are surgical procedures used for the management of vertebral compression fractures [8].
  • Dietary measures: Patients with osteoporosis should take daily doses of 1200-1500mg of calcium and 400-800 IU of vitamin D. Premenopausal women and men younger than 50 years of age (without risk) should receive a total of 1000mg of calcium daily. Postmenopausal women and men older than 50 years of age (with risk of osteoporosis) should receive 1200mg of calcium daily in their diet [9]. 
  • Exercise: Aerobic exercises such as walking and bicycling are highly recommended to maintain upright spinal posture include. Certain exercise training programs have positive impact in enhancing strength and maintaining balance of body [10].

Prognosis

The prognosis of osteoporotic diseases is good if the disease is detected in the early phases. Bone mineral density (BMD) is improved and fractures are reduced by proper medical and surgical approaches.

Etiology

The following factors contribute to osteopenia in both men and women:

Osteoporosis has endogenous as well as exogenous risk factors, which contribute to primary and secondary osteoporosis respectively.

The endogenous risk factors include:

The exogenous risk factors include:

Epidemiology

The incidence of osteoporotic lesions is 50% in women and 30% in men. In the United States, more than 10 million persons over age 50 are affected by osteoporosis and approximately 33.6 million people have osteopenia. The annual direct health care cost for osteoporotic lesions is $12 billion to $18 billion.

Pathophysiology

Bones naturally become thinner as people grow older. All people usually begin losing bone mass after the age of 30. In case of osteopenia, usually in middle age, existing bone cells are reabsorbed by the body faster than new bone is made. As this occurs, the bones lose minerals, becoming weaker with increased risk of fractures.

In osteoporosis, there is an increased bone resorption and reduced bone formation that results in reduced bone mineral density (BMD). In women after menopause, there is rapid reduction in bone mineral density as estrogen production is reduced. Estrogen affects indirectly cytokines and other growth factors in body. Estrogen deficiency thus leads to increased expression of RANKL that results to the recruitment of pro-osteoclasts as well as osteoclasts [3]. In contrast, aging is associated with a decreased supply of osteoblasts in proportion to demand.

Calcium and Vitamin D deficiency on other hand, play an essential role in causing osteoporotic conditions. Reduced calcium levels lead to secondary hyperparathyroidism. Parathyroid hormone in turn increases calcium resorption from bones, making them brittle and porous. Other conditions that lead to bone loss include endocrinal disorders and drugs like glucocorticoids. Corticosteroids inhibit osteoblast function and enhance osteoblast apoptosis.

Prevention

Primary prevention of the disease starts in childhood with diet enriched in calcium and vitamin D intake. Lifestyle modifications are helpful to some extent. Cigarette smoking, physical inactivity and intake of alcohol must be stopped.

Summary

Osteopenia and osteoporosis are the most common metabolic bone disorders affecting over 200 million people worldwide [1]. 

Osteopenia refers to the condition in which the bone mineral density (BMD) is lower than the normal peak level.

Osteoporosis is a skeletal disorder characterized by bone mineral density even lower than that in osteopenia that results in the destruction and fracture of bones. Osteoporosis can be primary or secondary.

Patient Information

Osteopenia and osteoporosis are conditions in which the bones become thin and weak. The chances of fractures therefore, become significantly higher. The disease is more common in older age group and postmenopausal women. Usually there are no symptoms and the disease is detected after a fracture. With proper treatment, diet and lifestyle changes, the disease has a good prognosis.
