Systemic lupus erythematosus (SLE) is a chronic inflammatory disease with manifold manifestations. SLE belongs to the family of autoimmune disorders, diseases that occur, when a mislead immune system attacks the body’s own structures. SLE can affect almost any organ system, thus its presentation and course are highly variable, and diagnosis and therapy may be challenging.

With the intention to classify SLE patients for research and surveillance studies and to support clinicians in confirming a diagnosis, a set of clinical and laboratory classification criteria has been developed and released by the American College of Rheumatology (ACR). The first classification criteria for SLE were originally published in 1971 [1,2]. They have been updated 1982 [3] and 1997 [4] to incorporate new immunologic knowledge and improve patient classification. In contrast to the 1987 criteria, the 1997 criteria have not been validated.

The most recent addendum to the classification criteria for SLE dates from 2012, when the Systemic Lupus International Collaborating Clinics (SLICC) group published a revision and validation of the ACR criteria [5].

Research Update: New Classification Criteria for Sjoegren’s Syndrome

Since the early 1960s almost a dozen different criteria for Sjögren’s syndrome (SS) have been published, both for classifying and for diagnosing that autoimmune disease. Recently, an international team of rheumatologists has published new classification criteria for Sjögren’s syndrome. In the April issue of the Arthritis Care & Research journal the authors propose clear and carefully worded guidelines.

Without question, these “new 2012 classification criteria for Sjögren’s syndrome” are urgently needed to better support etiologic and genetic research and therapeutic trials for Sjögren’s syndrome. Indeed, the new criteria are the first to be based solely on objective clinical tests!

Many other criterions have permitted various testing subjectivity to enable the classification of the disorder. In consequence, subjectivity has made standardisation of clinical trial inclusion something of a moving target, limiting comparability of research data across studies and impeding the needed robust clinical evaluation of possible new treatments. But criteria used for enrollment into clinical trials need to be clear, be easy to apply. And the new 2012 criteria agree to that demand. (more…)

The 2010 ACR – EULAR Rheumatoid Arthritis Classification Criteria in brief

In the September issues of their journals Arthritis and Rheumatism and Annals of the Rheumatic Diseases the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) present a new set of criteria for the classification of rheumatoid arthritis (RA).

Why do wee need “new” criteria for the classification of RA?

The 1987 ACR criteria have been criticised for their lack of sensitivity, especially in early disease. They rather describe the symptoms of fully developed late-stage RA. During the past decade, RA treatment has undergone dramatic changes (more…)
