Connective Tissue Diseases

Autoimmune connective tissue diseases are a heterogeneous group of diseases characterised by abnormal structure or function of one or more of the elements of the connective tissue, i.e., collagen, elastin, or the mucopolysaccharides.

Classically, the following diseases belong to this group:

  • SLE (systemic lupus erythematosus)
  • Scleroderma
  • Dermatomyositis/Polymyositis
  • Sjögren‘s Syndrome
  • Mixed Connective Tissue Disease

The detection of specific autoantibodies, the so-called antinuclear antibodies (ANA), may support the diagnosis of autoimmune connective tissue diseases and help in differential diagnosis as well as in prognosis.



For supporting the diagnosis of connective tissue diseases ImmunoDiagnostics offers a variety of tests.
