What is the best treatment for osteoporosis?
Anabolic therapy for osteoporosis. Until recently, calcium supplementation with vitamin D and hormone replacement therapy were the mainstays of treating osteoporosis associated with the menopause.
Is PTH anabolic or anabolic?
PTH(1-34), or teriparatide, exhibits many of the classical actions of the whole molecule. It is anabolic with respect to bone when used according to well-defined protocols. Bone microarchitecture is restored with increases in cortical thickness and in connectivity.
Does vitamin D help with osteoporosis?
Until recently, calcium supplementation with vitamin D and hormone replacement therapy were the mainstays of treating osteoporosis associated with the menopause. Hormone replacement therapy, indeed, was (and is) effective in preventing fracture, but is no longer to be considered to be a primary indication for this purpose.
What is idiopathic osteoporosis?
Idiopathic osteoporosis in men is an ill defined syndrome of low BMD and spinal fractures without associated hypogonadism or other definable etiology. By histomorphometry, these men often have low bone turnover, suggesting a possible defect in bone formation. Several groups of investigators have suggested that this syndrome is related to low serum IGF-I levels ( 31, 32 ). As the therapeutic options in males with osteoporosis are somewhat limited, and treatment for low bone turnover states, in general, is frustrating, the therapeutic potential for anabolic agents such as IGF-I in this condition should be quite high.
How does PTH work?
PTH is a principal regulator of calcium homeostasis in mammalian systems. PTH responds dynamically to changes in extracellular calcium via a cell surface calcium-sensing receptor. Increases in serum calcium suppress PTH release, whereas falling levels stimulate PTH release. Besides its acute effects on mobilizing skeletal calcium, PTH also stimulates 1α-hydroxylase activity in the kidney, thereby increasing serum 1,25-dihydroxyvitamin D levels. This, in turn, promotes calcium transport in the gastrointestinal tract. PTH also acts on the distal tubule to enhance reabsorption of filtered calcium. In sum, PTH is the center of a homeostatic mechanism, which has been finely tuned to serve mammals who millions of years ago moved from a calcium-rich ocean to a calcium-poor, land-based diet ( 38 ).
Is glucocorticoid osteoporosis a drug?
Glucocorticoid-induced osteoporosis (GIO) is the most common cause of drug-related osteoporosis. It is associated with rapid bone loss, fractures, and increased morbidity. Although bone formation is markedly impaired, there is also an increase in bone resorption. Several of the bisphosphonates have been shown to preserve BMD and reduce the risk of subsequent fracture in patients with GIO ( 62, 63 ). However, the bisphosphonates do not directly counteract the reduced bone formation characteristic of GIO. Hence, the use of PTH in combination with an antiresorptive agent to treat GIO is attractive. The seminal study in this regard comes from Lane et al., who conducted a randomized, 12-month, placebo-controlled trial with hPTH- (1–34) in 51 women with chronic inflammatory diseases ( e.g. rheumatoid arthritis) taking chronic glucocorticoids (>5 mg/day prednisone) who were already being treated with hormone replacement therapy ( 64 – 66 ). Women receiving PTH plus estrogen experienced an 11% increase in spine BMD by DXA compared with a 1.7% increase in those remaining on estrogen alone. There were no differences in hip or forearm BMD between groups, but by QCT of the spine, the increase in BMD was even greater (35%) in those women receiving PTH. Markers of bone turnover were increased by 3 months in the PTH treatment arm to nearly 150% of baseline, whereas resorption markers also were enhanced, but to a much lesser degree ( 64 – 66 ). Overall, the treatment was well tolerated. During the second year of the protocol, although PTH had been discontinued, a further increase in lumbar spine BMD of 15% was observed ( 64 ). These data establish that 1) GIO can be managed with combinations of PTH and estrogen; 2) despite the presence of an antiresorptive agent, PTH markedly induces bone formation; and 3) the actions of PTH on the skeleton persisted for at least 1 yr after treatment was discontinued ( 66 ).
Does PTH increase bone mass?
The PTH effect to improve bone mass and strength has been noted in rats, monkeys, dogs,and rabbits ( 46 – 48, 52 ). In contrast, the effects of PTH in mice are more heterogeneous, varying with the strain and showing more positive cortical effects than cancellous change.
Do statins inhibit HMG?
Third, the statins inhibit HMG coenzyme A reductase, a rate-limiting step in cholesterol biosynthesis. The bisphosphonates block bone resorption also by working on the cholesterol biosynthetic pathway, in this case by inhibiting a step further down that path ( i.e. farnesyl-pyrophosphate synthase).
Is sodium fluoride an anabolic agent?
Sodium fluoride was the first of the true anabolic agents to be used in the treatment of postmenopausal osteoporosis. Radiographic increases in bone mass were impressive in early studies with fluoride when administered to osteopenic individuals. Fluoride, in fact, has been used throughout the world for the treatment of osteoporosis for nearly 4 decades, although in the United States it is not a Food and Drug Administration-approved drug for osteoporosis. One of the reasons for this is the conflicting results of the early RPCTs in which the use of fluoride was associated with marked increases in vertebral BMD but no change in vertebral fracture incidence. Moreover, the risk of nonvertebral fractures may have been somewhat higher in the trials using a relatively high daily dosage of sodium fluoride, 75 mg ( 1, 1A ). Side-effects, consisting of upper gastrointestinal symptoms and a lower extremity pain syndrome, were common. The investigation of Meunier et al. was also disappointing when fluoride was used in somewhat lower dosage ( 1B ). Subsequently, Pak and his associates reported on a lower dose, slow release formulation of sodium fluoride in which the pharmacokinetics and serum levels improved the therapeutic/toxicity index. Using this form of fluoride, Pak et al. showed a 50% reduction in vertebral fracture incidence along with impressive increases in bone mass ( 2, 3, 3A ). More recently, Ringe, Reginster, and their colleagues reported positive results with low dose but a different formulation of fluoride, monofluorophosphate ( 11, 12, 12A ). Despite the potential for this agent, especially when used in lower dosages and more favorable formulations so as to reduce or eliminate gastrointestinal side-effects, consensus about its clinical utility has still not been reached. Reflecting that ambiguity, the U.S. Food and Drug Administration has not approved any fluoride preparation for the prevention or treatment of postmenopausal osteoporosis, and it appears unlikely that position will change in the near future.
What are the best medications for osteoporosis?
Which medications can help treat osteoporosis? 1 block the breakdown of bone (anti-resorptive therapies). Examples include bisphosphonates such as alendronate (Fosamax), which is a pill, and zoledronate (Reclast), which is given intravenously. Other types of anti-resorptive agents include raloxifene (Evista) and denosumab (Prolia). 2 enhance the formation of bone (anabolic therapies). Examples include teriparatide (Forteo) and abaloparatide (Tymlos).
What is the role of sclerostin in bone formation?
Sclerostin is a protein that helps regulate bone metabolism. Produced by osteocytes (bone cells), it inhibits bone formation (making new bone). Romosozumab binds sclerostin, which keeps it from blocking the signaling pathway for new bone formation. The result is an increase in new bone.
How many people are affected by osteoarthritis?
It affects 10 million people in the United States: approximately eight million women and two million men. As bone weakens, people are more likely to experience fractures, especially in the spine, hip, and forearm. This causes pain, diminishes a person’s ability to function, and reduces quality of life. Anything that can lower the risk of ...
How long does romosozumab last?
The medication is injected once a month using two separate prefilled syringes for a full dose. Romosozumab should only be taken for one year, because its bone-making activity wanes after 12 months. Women using this therapy should also make sure they get enough calcium and vitamin D during treatment.
Does romosozumab have long term effects?
We do not yet have long-term data on romosozumab. But a dual effect (increasing bone formation and decreasing bone resorption) makes it a welcome addition to available treatments for osteoporosis — at least for postmenopausal women at high risk for fracture.
Is romosozumab good for osteoporosis?
Romosozumab is a welcome addition to our treatment options for postmenopausal women with osteoporosis who are at high risk of fracture . It results in rapid and profound increases in bone density and reduction in the risk of fractures after 1 year of treatment.
Does bisphosphonate affect bone?
But given what we know about the effects of bisphosphonates on bone remodeling, the findings seem plausible. In the short term, slowing bone resorption increases bone density. But in the long run, it may impair new bone formation and reduce the bone’s ability to repair microscopic cracks from normal wear and tear.
