Definition

Many with obvious autoimmune" Inflammatory rheumatic disease cannot be defined (classified) in a particular diagnosis. This is because the disease has symptoms and findings from two or more conditions without a single diagnosis being adequate. Early in the course of the disease, yet unclear symptoms may contribute to more Systemic connective tissue diseases: are difficult to classify. However, undifferentiated systemic connective tissue disease will often remain unclassified (in about 80%) even after the entire course of the disease.

Undifferentiated systemic connective tissue disease is thus distinguished from the following:

Occurrence

About 25% of systemic connective tissue disease remains unclassified.

Symptoms (a selection) of undifferentiated systemic connective tissue disease

  • Raynaud's phenomenon
  • Arthritis
  • Swollen ("puffy") fingers
  • Eczema (dermatitis)
  • Hair loss (alopecia)
  • Dry eyes and mouth
  • Manifestation in various internal organs
  • Antibodies of different types at the same time that can accommodate multiple diseases (controlled over time)
    • ANA (antinuclear antibody) with different combinations of subgroups, often including SSA / Ro52)
    • Ani-CCP without classical rheumatoid arthritis
  • In blood samples, the number of blood cells may be low (leukopenia, thrombocytopenia, anemia). However, it is unusual with the low number of all types at the same time (investigate bone marrow for other illness)
  • Capillaroscopy can show signs of disease in small blood vessels
  • Effect of immunosuppressive drugs

Diagnosis

One wants to describe the symptoms, investigation findings and the course of the disease so that one can map these a clear, unambiguous diagnosis. It is then easier to inform about the condition and follow-up can follow diagnosis-specific recommendations. In undifferentiated systemic connective tissue disease, the individual variation is large within the same condition. One is based on the individual's symptoms and examination findings and describes the individual case.

Incorrect diagnosis (similar conditions, differential diagnoses)

The treatment

An individually adapted treatment is at least as relevant as with other systemic connective tissue diseases. Some do not need medication, while in others fixed use of potent drugs can prevent serious organ damage.

Prognosis

In general, undifferentiated systemic connective tissue disease has a good prognosis because injuries to internal organs rarely occur. However, the course is characterized by the individual symptoms.
