Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Disorders of Erythrocytes

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Essential Minerals for Bone Health

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

The Functions of the Skeletal System

The Functions of the Skeletal System

The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

Sus antecedentes:

La anemia y la enfermedad ósea coexisten frecuentemente en afecciones crónicas como las hemoglobinopatías y la enfermedad renal crónica.
La salud ósea se ve comprometida por factores como la expansión de la médula, la sobrecarga de hierro, la disfunción endocrina y las alteraciones del metabolismo mineral, lo que aumenta el riesgo de fracturas.
Los avances terapéuticos actuales para la anemia pueden tener efectos subestimados en la salud ósea, detectándose a menudo la osteoporosis después de una fractura.

Conclusiones:

Existe una necesidad crítica de reconocer los riesgos esqueléticos asociados con la anemia y sus tratamientos.
La monitorización de los niveles de FGF-23 y fósforo es crucial, especialmente en pacientes que reciben terapias combinadas de antiresortivos y hierro parenteral.
Se proporcionan recomendaciones prácticas para tender un puente entre la comprensión mecanicista y la práctica clínica para mejorar el manejo de la salud ósea en pacientes anémicos.
