Systemic Sclerosis-Specific Antibodies: Novel and Classical Biomarkers

Abstract: Disease-specific autoantibodies are considered the most important biomarkers for systemic sclerosis (SSc), due to their ability to stratify patients with different severity and prognosis. Anti-nuclear antibodies (ANA), occurring in subjects with isolated Raynuad’s phenomenon, are considered the strongest independent predictors of definite SSc and digital microvascular damage, as observed by nailfold videocapillaroscopy. ANA are present in more than 90% of SSc, but ANA negativity does not exclude SSc diagnosis:… Show more

“…However, this technique is insufficient to identify specific ANAs except for anti-centromere antibodies. Therefore, additional techniques such as ELISA, immunodiffusion or Western immunoblotting can be used to determine the patients’ individual specific antigenic targets [ 71 ].…”

“…To further explain clinical differences of ANA subspecificities, Clark et al performed a transcriptional and proteomic analysis of blood and skin of SSc patients with anti-topoisomerase I and anti-RNA polymerase III antibody specificities, revealing pathogenetic differences between ANA-based subgroups [ 78 ]. For the association of SSc-specific ANAs with corresponding clinical phenotypes, we refer to recently published reviews, e.g., by Cavazzana et al [ 71 ] or Stochmal et al [ 79 ]. In addition, recently, further ANAs were identified in subsets of SSc patients.…”

“…103,104 For clinical practice, simple and cost-efficient methods such as ELISA and immunoblotting have become established. 105 In our study we used both methods for the determination of ACA and Topo-1 and could show a good agreement for the EUROLINE blot compared to ELISA. However, it should be noted that both methods are based on similar principles and thus share common sources of error, such as non-specific binding and cross-reactivity.…”

“…However, it should be noted that both methods are based on similar principles and thus share common sources of error, such as non-specific binding and cross-reactivity. 42,105 Furthermore, it has to be considered that the other antibodies we determined and on which our cluster analysis is based were only determined with a single technique. Mierau et al analysed sera of 863 SSc patients using different methods including IIF, a comparable line immunoassay as we did, immunoprecipitation and immunodiffusion.…”

“…For the determination of antibodies in SSc, different methods exist, each of which has strengths and weaknesses ( 106 , 107 ). For clinical practice, simple and cost-efficient methods such as ELISA and immunoblotting have become established ( 108 ). In our study we used both methods for the determination of ACA and Topo-1 and could show a good agreement for the EUROLINE blot compared to ELISA.…”
