Hydrocortisone and Prednisolone. Following the discovery of the antiinflammatory actions of cortisone (1) and cortisol (2), there was a need not only to develop highly efficient routes to the corticoids, but to discover novel stmctures with fewer side effects than those of the corticoids, eg, sodium and water retention, reduced carbohydrate tolerance (steroid diabetes), osteoporosis, and depressed host defense. 

Other Calcium Disorders. In addition to hypocalcemia, tremors, osteoporosis, and muscle spasms (tetary), calcium deficiency can lead to rickets, osteomalacia, and possibly heart disease. These, as well as Paget s disease, can also result from faulty utilization of calcium. Calcium excess can lead to excess secretion of calcitonin, possible calcification of soft tissues, and kidney stones when combined with magnesium deficiency. 

Phosphorus Disorders. Phosphoms nutrient deficiency can lead to rickets, osteomalacia, and osteoporosis, whereas an excess can produce hypocalcemia. Faulty utilisation of phosphoms results in rickets, osteomalacia, osteoporosis, and Paget s disease, and renal or vitamin D-resistant rickets. 

In the treatment of diseases where the metaboUtes are not being deUvered to the system, synthetic metaboUtes or active analogues have been successfully adrninistered. Vitamin metaboUtes have been successfully used for treatment of milk fever ia catde, turkey leg weakness, plaque psoriasis, and osteoporosis and renal osteodystrophy ia humans. Many of these clinical studies are outlined ia References 6, 16, 40, 51, and 141. The vitamin D receptor complex is a member of the gene superfamily of transcriptional activators, and 1,25 dihydroxy vitamin D is thus supportive of selective cell differentiation. In addition to mineral homeostasis mediated ia the iatestiae, kidney, and bone, the metaboUte acts on the immune system, P-ceUs of the pancreas (iasulin secretion), cerebellum, and hypothalamus.

Furthermore, peptidomimetic SH2 domain inhibitors for Src, such as AP-22408 have been designed that interfere with effector binding and thereby disrupt signal transduction. AP-22408 decreases bone resorption in animal studies and may be a promising drug to treat osteoporosis and other bone diseases, such as Paget s disease and osteolytic bone metastasis. 

Several other inhibitors of nonreceptor PTKs are currently in development but only a few of them are studied in clinical trials. Noteworthy, Dasatinib does not only inhibit c-Abl, but also potently blocks Src activity, a property that may contribute to its beneficial clinical effects in CML. Other kinase inhibitors being developed that inhibit c-Abl and/or Src are AZD-0530, AP-23994, PD-0183805, SU-6656, and Bosutinib (SKI-606). Furthermore, peptidomimetic SH2 domain inhibitors for Src, such as AP-22408 have been designed that decrease bone resorption and may be promising drugs to treat osteoporosis and other bone diseases, such as Paget s disease and osteolytic bone metastasis. 

The bisphosphonates are drags used to treat musculoskeletal disorders such as osteoporosis and Fhget s disease. This chapter will discuss the use of these drugs in the treatment of osteoporosis.

The early stages of bone pathology in rheumatoid disease manifest as periarticular osteoporosis and juxta-articular bone erosion. Osteoclast overactivity is the predominant influence in such bone erosion and NO has a direct inhibitory efiect on osteoclastic bone resorption (MacIntyre et al., 1991). Endothelial cells, present in abundance and in close proximity to the osteoclast may therefore play a role in down-regulating osteoclast activity through the production of NO. Since the osteoclast is of macrophage lineage, it is likely to be... 

Lipid abnormalities are associated with a wide spectrum of pathological conditions. In particular, recent advances have been made in understanding the role of lipoproteins in coronary heart disease (Davies and Woolf, 1993). However, included within the spectrum of diseases associated with perturbations of lipid metabolism are a number of musculoskeletal problems including inflammatory polyarthritis, tenosynovitis, osteoporosis and bone cysts.

Many of the risk factors for osteoporosis and osteoporotic fractures are predictors of low bone mineral density, such as age and ethnicity (Table 53-1). The most important risk factors for fracture are low bone mineral density, personal history of adult fracture, age, and family history of osteoporotic fracture. Other important risk factors for osteoporosis and osteoporotic fractures include menopausal status, smoking status, and low body weight. As bone mineral density decreases, the risk of fracture increases. However, the threshold at which individual patients develop a fracture varies, and other factors may play a role in fracture susceptibility. One such factor that can influence the development of fracture is falling.
