[Pharmacotherapy of osteoporosis: evidence-based clinical practice].

Since the foundation of the DVO ("Dachverband Osteologie") in 1999, it has been the continuous ambition to implement evidence-based medicine in the clinical course for the effective diagnosis and treatment of osteoporosis. This aim was addressed by the implementation of general guidelines (DVO) in 2003. These guidelines (DVO) offer strategies for diagnosis and treatment of osteoporosis in postmenopausal women, osteoporosis in elderly women and glucocorticoid-induced osteoporosis. Evidence-based treatment of osteoporosis recommends the supplementation with calcium and vitamin D, considering antiresorptive therapy antifracture efficacy is proven for the bisphosphonates alendronate, ibandronate and risedronate on the one hand and the SERM raloxifen on the other hand. On the basis of valid data from randomized, placebo-controlled clinical trials, new therapy regimen like rhPTH1-34 (teriparatide) or strontium ranelate fulfill the recommendation criteria for the guidelines (DVO). Effective treatment of glucocorticoid-induced osteoporosis includes supplemental calcium and vitamin D and antiresorptive agents like the bisphosphonates alendronate, risedronate and etidronate according to the guidelines (DVO).

[The successful development of bisphosphonates in the therapy of osteoporosis].

In the last 30 years bisphosphonates have been used in the treatment of different bone diseases. Bisphosphonates in their oral pharmaceutical form are an established and approved medication in osteoporosis treatment for years. Latest research developed more potent bisphosphonates in different application forms: oral and parenteral. Therefore, their prospects for medical treatment could be enlarged to the fields of oncology, hematology, and osteology. Bisphosphonates are innovative in case of adjuvant therapy as well as in adequate pain therapy. In the medical treatment of osteoporosis and metabolic osteopathies bisphosphonates could be rightly denoted as groundbreaking.

Validation of a new automated immunoassay for measurement of intact osteocalcin.

Bone turnover is assessed indirectly by measurement of biochemical markers of bone turnover. Osteocalcin, a 49-amino-acid protein is a major noncollagenous protein of bone matrix, synthesized by osteoblasts and odontoblasts. Various assays exist for assessment of osteocalcin and concentrations in the same serum or plasma sample may vary enormously. The used antibodies may recognize intact osteocalcin and/or circulating fragments of osteocalcin. We here describe and validate a new automated immunoassay system for measurement of intact osteocalcin (DPC IMMULITE assay) using monoclonal antibodies (mouse) against the C-terminus of osteocalcin (AA 44-49). For detection polyclonal antibodies (goat) directed against the N-terminus (AA 1-17) conjugated with alkaline phosphatase are used. While different laboratory assays show marked clinical discordance, we evaluated our results comparatively to an established IRMA method (Nichols). We observed a highly significant correlation between both assays (r = 0.9352, p < 0.0001, n = 286) for healthy persons and also for patient samples (osteoporosis, diabetes type 1, rheumatoid arthritis). Very low inter- and intraassay covariance as well as highly significant linearity (analytical recovery near 100%) tested by serial dilutions were demonstrated for the DPC IMMULITE intact osteocalcin assay. We conclude that the IMMULITE assay is a useful method for assessment of intact osteocalcin giving valuable results in comparison to an established non-automated assay.
