[Dosage of ionized calcium in osteo-articular pathology]
Abstract:
The dosage of calcium ionized serum using a selective electrode, was performed in a series of controls and patients with osteo-articular diseases. Normal values were 43 mg/l between 20 and 50 years of age, and 41 mg/l after 60 years. The level of ionized calcium, when given as a percentage of total blood calcium, did not decrease with age (normal value : 44%). It was increased in hyper-parathyroidism, rhumatoid polyarthritis and lytic bone metastasis. It did not vary in Paget's disease, osteoporosis, osteomalacia, condensing metastasis, Kahler's disease and spasmophilia. The ionized calcium in definitely diminished in hypoparathyroidism.

Bone Disorders
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...

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 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
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...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
