Zusammenfassung
Die ankylosierende Spondylitis (AS), Prototyp der Spondyloarthritiden (SpA), ist eine häufige entzündlich rheumatische Erkrankung. In den letzten Jahren sind Outcome-Parameter entwickelt worden, die Ausmaß und Aktivität der Erkrankung erfassen. Zu diesen gehören „Bath AS Disease Activity Index“ (BASDAI), „Bath AS Functional Index“ (BASFI), „Bath AS Metrology Index“ (BASMI), numerische Rating-Skalen zum allgemeinen Schmerz, nächtlichen Schmerz, zur allgemeinen Krankheitsaktivität, zum allgemeinen Arzturteil sowie verschiedene Lebensqualitätsfragebögen wie „Short Form 36“ (SF-36) oder „Euroquol 5 Dimensions“ (EQ-5D) und als AS- spezifischer Fragebogen der „ASQuol“. Diese bilden die Grundlage für die Durchführung klinischer Studien. Die ASessments-in-Ankylosing-Spondylitis- (ASAS-) Improvement-Kriterien sind entwickelt worden, um den Kurzzeiteffekt von nichtsteroidalen Antirheumatika (NSAR) zu beurteilen, und weiterentwickelt worden, um die hocheffektiven Biologikatherapien einzuschätzen. Zur Beurteilung der Röntgenbilder der Sakroiliakalgelenke (SIG) im Verlauf werden die radiologischen Kriterien, die den modifizierten New-York-Kriterien zugrunde liegen, genutzt. Für die Wirbelsäule ist der Bath AS Radiology Index (BASRI) eher für den klinischen Alltag sinnvoll, während der modifizierte Stokes AS Spinal Score (mSASSS) sensitiver zur Verlaufsbeobachtung bei klinischen Studien ist. Weitere Scores zur Beurteilung von MRT-Aufnahmen der Wirbelsäule und der SIG werden derzeit entwickelt. Insgesamt konnte mittels dieser neuen Outcome-Parameter die hohe Wirksamkeit der TNF-α-Blocker belegt werden. Es konnte aber auch gezeigt werden, dass konventionelle krankheitsmodifizierende Antirheumatika bei der axialen Form der SpA nicht wirksam sind.
Abstract
Ankylosing spondylitis (AS) is a frequent inflammatory rheumatic disease and prototype of the Spondyloarthitides (SpA). During the last years outcome parameters have been developed to evaluate different aspects of the disease. Among these are the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Metrology Index (BASMI), numeric rating scales for general pain, night pain, patients and physicians global assessment, as well as questionnaires to evaluate quality of life as the short Form (SF)- 36, Euroquol 5 Dimensions (EQ-5D), or the AS specific the ASQuol. These outcome parameters are the basis to conduct clinical trials. The ASessements in AS (ASAS) improvement criteria were developed to evaluate the short term efficacy of Non-Steroidal Antirheumatic Drugs (NSAIDs) and adjusted for the measurement of the high efficacy of the TNF-alpha blocking agents. To examine the x-rays of sacroiliac joints (SIG), the radiological criteria as part of the modified New York criteria are mostly used. For the x-rays of the spine the Bath AS Radiology Index (BASRI) is valuable in daily practice, but the modified Stokes AS Spine Score (mSASSS) is more sensitive for clinical trials. To examine Magnetic Resonance Images (MRI) of SIG and spine also scores are currently developed. Altogether, using the new outcome parameters it was possible to demonstrate the strikingly high efficacy of the TNF-alpha blocking agents. However, it could also be shown that conventional disease modifying antirheumatic drugs (DMARDs) are not effective in the treatment of the axial forms of SpA.
