Proteína Gla ósea sérica: un marcador específico para la formación ósea en la osteoporosis posmenopáusica
Lancet (London, England)
|May 19, 1984
Resumen
La Gla-proteína ósea sérica (BGP), también conocida como osteocalcina, es un marcador específico para la formación ósea en la osteoporosis posmenopáusica (PMO). Los niveles elevados o reducidos de BGP pueden predecir los perfiles histológicos de formación ósea en pacientes con PMO.
Área de la Ciencia:
- Endocrinología Endocrinología.
- La ortopedia es la ortopedia.
- La bioquímica es la bioquímica.
Sus antecedentes:
- La osteoporosis posmenopáusica (OMP) es un problema de salud importante.
- Los marcadores precisos para la formación ósea son cruciales para el diagnóstico y el manejo de la PMO.
Objetivo del estudio:
- Evaluar la proteína Gla ósea sérica (BGP) como un marcador específico para la formación ósea en la osteoporosis posmenopáusica no tratada (PMO).
- Para evaluar la correlación de la BGP con los índices histomorfométricos de formación y resorción ósea.
- Para determinar si el BGP puede predecir el perfil histológico de la formación ósea en pacientes con OMP.
Principales métodos:
- Los niveles séricos de BGP se midieron en 26 pacientes con OMP no tratados y 35 controles de edad similar.
- Se analizaron las biopsias óseas para los índices histomorfométricos, incluido el volumen osteoideo, las superficies osteoideas y la tasa de formación ósea.
- Los pacientes se clasificaron en grupos de formación osteoide alta (HF), normal (NF) y baja (LF) en función de los resultados de la biopsia.
Principales resultados:
- Los niveles séricos de BGP mostraron diferencias significativas entre los grupos de HF, NF y LF, siendo más altos en HF y más bajos en pacientes con LF.
- El BGP sérico se correlacionó positivamente con los índices de formación ósea, pero no con las superficies de reabsorción.
- La fosfatasa alcalina sérica y la hidroxiprolina urinaria no discriminaron efectivamente entre los grupos de pacientes ni se correlacionaron con los índices histomorfométricos.
Conclusiones:
- El BGP sérico es un marcador específico y valioso para evaluar la formación ósea en la OMP.
- BGP puede predecir el perfil histológico de la formación ósea en pacientes con PMO.
- El suero BGP puede ayudar en la investigación y evaluación del tratamiento de la PMO.

Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
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...

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...

Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
