About Rickets

Overview

Rickets is a disease that primarily affects children and occurs when the newly formed bone tissue fails to mineralize properly at the growth plates of long bones. Rickets is specifically a pediatric disease and can only occur before the fusion of the end of long bones. If rickets occurs after this fusion, it is referred to as osteomalacia in adults. The presence of rickets has been documented since the 17th century, and it is known that vitamin D plays a crucial role in the absorption and utilization of calcium for bone health. Rickets can be caused by various conditions that interfere with vitamin D absorption and metabolism, such as renal, gastrointestinal, hepatic, or metabolic diseases. Despite efforts to fortify food with vitamin D, rickets remains prevalent worldwide, including in industrialized countries.

Causes and Risk Factors

The causes of Rickets are related to a failure of maturation and mineralization of the growth plate and bone matrix in growing children. This occurs due to chronically low levels of calcium and phosphate in the body, which disrupts the normal bone development process. Rickets can be classified into calcipenic rickets, caused by inadequate dietary calcium and/or vitamin D deficiencies, and phosphopenic rickets.

Non-modifiable risk factors are risk factors that cannot be changed. The non-modifiable risk factors for rickets include:

• Increasing age
• Genetic predispositions, such as a positive family history of rickets or related conditions

The modifiable risk factors for Rickets are largely influenced by individual habits and lifestyle choices. These include:

• Poor dietary habits, particularly a low intake of vitamin D and calcium-rich foods
• Lack of exposure to sunlight, which helps the body produce vitamin D
• Not taking vitamin D supplements despite being at high risk for developing rickets

It is recommended to maintain a healthy diet, get enough sunlight exposure, and consider vitamin D supplementation if at risk for rickets. Remember to consult with your healthcare professional for personalized advice.

Symptoms

The most common early symptoms of rickets include:

• Reluctance for food and poor weight gain
• Delayed start of walking
• Unsteady gait
• Joint stiffness and pain
• Muscle weakness, especially in the thighs

As rickets progresses or becomes more severe, other common symptoms may occur, such as:

• Bone pain or tenderness
• Bones that grow slowly
• Bowed or curved legs
• Soft and easily breakable bones
• Premature loss of primary teeth
• Dental cavities and irregularities
• Wide joints in the elbows and wrists
• Large forehead or abdomen
• Unusual shape to the ribs and breastbone

It's important to note that these symptoms can vary depending on the type of rickets and individual cases. If you suspect you or your child may have rickets, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Diagnosis

To diagnose rickets, the following examinations, tests, and procedures are commonly performed:

• Physical exam: The healthcare provider will look for physical signs of rickets, such as bowed legs or a soft skull.
• Lifestyle habits assessment: The doctor may ask about diet and sun exposure to gather more information.
• Blood tests: These can check for low levels of calcium and phosphorus and high levels of alkaline phosphatase. They can also check the blood’s acidity.
• X-rays: These may reveal calcium loss in bones or alterations in bone structure.
• Bone biopsy (rarely used): This can confirm rickets but is not commonly performed.
• Genetic testing: This can help identify any genetic changes associated with Rickets.
• Imaging studies: Such as an MRI, may be recommended to assess bone health.
• Clinical procedures: These may vary depending on the body system being evaluated and can be performed by different healthcare providers.

Remember, it's important to follow up with your healthcare provider if your symptoms worsen or change. They will guide you through the diagnosis process.

Treatment Options

The goals of treatment for rickets are to correct or improve the condition based on clinical and biochemical parameters. Here are the different types of treatments and therapies recommended for rickets, along with how they work to achieve the treatment goals:

Supplements:

• Vitamin D supplements: Depending on the underlying cause, a doctor may prescribe vitamin D supplements to maximize the individual's intake of calcium, phosphate, and vitamin D. This helps in promoting proper bone mineralization.
• Calcium and phosphorus supplements: In cases where rickets results from a poor diet or genetic causes, doctors may prescribe calcium and phosphorus supplements to support bone health.

Therapeutic procedures:

• Enzyme replacement therapy (ERT): For patients with hypophosphatasia, ERT may be considered on a trial basis to evaluate its efficacy in reducing pain and improving symptoms.
• Physical therapy: For mild pain, conservative treatment with physical therapy can be beneficial. It helps in relieving pain, improving muscle strength, and enhancing overall mobility.

Health behavior changes:

• Sunlight exposure: Increasing exposure to sunlight can help the body produce vitamin D naturally.
• Dietary changes: Consuming foods rich in vitamin D such as eggs, fatty fish (salmon, tuna), and fortified foods (milk, cereals) can contribute to adequate vitamin D intake.

It is important to note that these recommendations should be discussed with a healthcare professional as they can provide personalized advice based on individual needs. Medication dosing may be affected by many factors, so it's crucial to consult with a healthcare professional regarding dosing for your specific situation. Other side effects can occur, so it's essential to check with your healthcare professional or read the information provided with your medication for additional side effect information.
