Summary
Aim
Reasonable application of laboratory parameters in prevention, diagnosis, treatment and therapy monitoring of osteoporosis.
Target groups
Physicians from different specialist disciplines (general medicine, geriatrics, gynaecology, urology, internal medicine—especially endocrinology and metabolism, nephrology, laboratory medicine, rheumatology, nuclear medicine, orthopaedics, paediatrics, rehabilitation and physical medicine, radiology, social medicine, transplantation medicine, accident surgery), moreover social insurances, hospitals and self-help groups.
Background
Evaluation of aetiology of bone disorders, widening of the therapeutic spectrum for diseases of bone and knowledge on biochemical markers of bone turnover. Improvements in judging the success of therapy and in monitoring the compliance of patients. Research perspectives.
Bases
Scientific literature and guidelines, consensus meetings.
Résumé
Basic and specialized laboratory investigations are important in differentiation between primary and secondary osteoporosis for an adequate therapy. Biochemical markers of bone turnover are an additional aid in evaluation of individual fracture risk. These markers identify responders to bone therapy faster than surveillance of bone mineral density, which helps to improve patient’s compliance too. Characteristics, preanalytic precautions and applications are presented for selected markers of bone resorption and formation and for parameters regulating bone metabolism.
Zusammenfassung
Ziel

Zielgruppe
Ärztinnen und Ärzte für Allgemeinmedizin, Geriatrie, Gynäkologie, Urologie, Innere Medizin (besonders Endokrinologie und Stoffwechsel), Nephrologie, Med. und Chem. Labordiagnostik, Onkologie, Rheumatologie, Nuklearmedizin, Orthopädie, Pädiatrie, Rehabilitation und Physikalische Medizin, Radiologie, Sozialmedizin, Transplantationsmedizin, Unfallchirurgie, sowie Sozialversicherungsanstalten, Krankenanstalten, Selbsthilfegruppen.
Hintergrund
Abklärung der Ätiologie von Knochenerkrankungen. Wachsendes Spektrum der Therapiemöglichkeiten von Knochenerkrankungen und der biochemischen Marker des Knochenstoffwechsels. Verbesserungen in der Beurteilung des Therapieerfolgs und bei der Überwachung der Compliance von Patienten. Forschungsperspektiven.
Grundlagen
Wissenschaftliche Literatur, Leitlinien und Konsens-Gespräche.
Fazit
Routine- und Spezial-Laboruntersuchungen sind für die Unterscheidung zwischen primärer und sekundärer Osteoporose und für die Wahl einer angemessenen Therapie wichtig. Biochemische Marker des Knochenumbaus sind ein zusätzliches Hilfsmittel bei der Abschätzung des individuellen Frakturrisikos. Mit diesen Markern kann ein Ansprechen auf eine knochenspezifische Therapie rascher erfasst werden als mit der Überwachung der Knochenmineraldichte, dies hilft auch die Compliance der Patienten zu verbessern. Eigenschaften, Präanalytik und Anwendung von ausgewählten Markern für Knochen- Resorption und Anbau und von Parametern, die den Knochenstoffwechsel regulieren, werden präsentiert.
