Zusammenfassung
Die rheumatoide Arthritis gefährdet Knochen nicht nur lokal, sondern stellt auch einen wesentlichen Risikofaktor zur Entwicklung einer Osteoporose dar, die durch eine verminderte Knochenqualität und ein erhöhtes Frakturrisiko definiert ist. Vor allem die proinflammatorischen Zytokine Tumornekrosefaktor α (TNF-α), Interleukin (IL)-6 und IL-17 tragen zur lokalen und systemischen Knochendestruktion bei. Obwohl die Entzündung mittels Glukokortikoiden gut in Schach gehalten werden kann, ist auch ihre Verabreichung mit einem erhöhten Frakturrisiko verbunden. Aus diesen Gründen ist auf eine ausreichende Kalzium- und Vitamin-D-Zufuhr zu achten. In vielen Fällen ist auch die Messung der Knochendichte zu empfehlen.
Abstract
Rheumatoid arthritis (RA) is a bone-destructive disease that is a serious risk factor for the development of osteoporosis, which is defined by a loss in bone quality and an increased fracture risk. The proinflammatory cytokines tumor necrosis factor-α (TNFα), interleukin-6 (IL-6) and IL-17, in particular, contribute to local and systemic bone loss in RA. While effectively reducing inflammation, glucocorticoids add to the fracture risk. Therefore, an adequate supply of calcium and vitamin D is essential. For many patients with RA, bone density measurements are recommended.
