Undifferentiated Connective Tissue Disease

 

 

Overview

When the symptoms and lab test results of a systemic connective tissue disease are present but do not meet enough characteristics for a specific diagnosis (such as rheumatoid arthritis or lupus).

Common Symptoms

Joint pain, rashes, dry eyes/mouth, fever, sun sensitivity, hair loss (alopecia), Raynaud’s phenomenon, muscle weakness, fatigue, blood clots, anemia, and lung and heart inflammation that causes chest pains.

Coexisting Conditions

Thyroid diseases, endothelial dysfunction, anxiety, and pulmonary fibrosis.

Risk Factors

Females are more likely to develop UCTD than men. Furthermore, studies have found that individuals with low levels of vitamin D are more susceptible to developing UCTD than those with sufficient levels. Finally, the disease has been seen more among those between the ages of 30 and 50 than in other age groups.
