Zusammenfassung
Hintergrund
Die idiopathischen inflammatorischen Myositiden sind chronische, systemische Autoimmunkrankheiten, die durch symmetrische, proximale Muskelschwäche charakterisiert sind. Die klinisch-pathologische Einteilung scheint heutzutage obsolet zu sein, deshalb ist eine immunserologische Klassifikation erstellt worden.
Fragestellung
Einer der wichtigsten Phänotypen der Myositiden ist die Dermatomyositis. In dieser Gruppe spielen die dermatomyositisspezifischen Autoantikörper eine bedeutende Rolle, die hier mithilfe der Fachliteratur dargestellt werden.
Material und Methoden
Nach dem Überblick der wichtigsten Informationen über Dermatomyositis wird nicht nur der seit Langem bekannten Autoantikörper (anti-Mi-2) vorgestellt, sondern auch kürzlich identifizierte Autoantikörper: anti-TIF1γ, anti-NXP2, anti-SAE und anti-MDA5. Im Mittelpunkt stehen die Häufigkeit dieser Autoantikörper, die verbundenen Symptome bei Erwachsenen und Jugendlichen sowie einige spezielle Relationen aus der Fachliteratur.
Ergebnisse
Alle Studien bestätigen, dass diese Autoantikörper v. a. bei Dermatomyositis nachweisbar sind. Aufgrund der aktuellsten Literatur sind die neu identifizierten Autoantikörper bei Jugendlichen mit Myositis häufiger, als die klassischen Autoantikörper (anti-Jo-1, anti-Mi-2, anti-SRP).
Schlussfolgerungen
Es ist sinnvoll, diese Autoantikörper nachzuweisen, um während des Krankheitsverlaufs die Symptome und Prognose besser abschätzen zu können.
Abstract
Background
Idiopathic inflammatory myopathies are chronic systemic autoimmune diseases characterized by symmetrical proximal muscle weakness. The clinicopathological subdivision nowadays appears to be obsolete which is why the immunoserological classification has been developed.
Objectives
Dermatomyositis represents one the most important subsets of idiopathic inflammatory myopathy and dermatomyositis-specific autoantibodies play a significant role in this subset. The aim of this article was to present these autoantibodies with the help of the literature.
Methods
This article presents the most important information about dermatomyositis including not only the classical anti-Mi-2 autoantibody but also the recently detected anti-TIF1γ, anti-NXP2, anti-SAE and anti-MDA5 autoantibodies. The focus is on the frequency of these autoantibodies, the associated symptoms in adult and juvenile dermatomyositis cases and some special aspects from the literature.
Results
All of the studies confirmed that these autoantibodies are particularly detectable in dermatomyositis. The results from the literature have recently shown that the frequency of the autoantibodies detected in juvenile cases is higher than the frequency of traditional autoantibodies (e.g. anti-Jo-1, anti-Mi-2 and anti-SRP).
Conclusion
It is useful to detect these autoantibodies in order to be able to make a better assessment of the clinical symptoms and prognosis during the course of the disease.
