Undifferentiated Connective Tissue Disease

Undifferentiated connective tissue disease, or UCTD for short, is a systemic autoimmune disease. This means that the body’s natural immune system does not behave normally. Instead of serving to fight infections such as bacteria and viruses, the body’s own immune system attacks itself. In UCTD, autoimmunity may cause the immune system to attack specific parts of the body, resulting in a variety of problems.


What are Some of the Symptoms of UCTD?
Because UCTD can affect so many different parts of the body, UCTD often has many symptoms.

Who Gets UCTD?
People of all races and ethnic backgrounds develop UCTD. It occurs more commonly in women and rarely occurs in children. Typically, UCTD begins when people are between the ages of 30 and 55.

What Causes UCTD?
Although the cause of UCTD is not known, we do know that UCTD is an autoimmune disease. The abnormal immune response may lead to inflammation and damage of the various organs that are involved in a given individual.

How is UCTD Diagnosed?
It is often difficult to diagnose UCTD. A specialist in autoimmune diseases, known as a rheumatologist, is usually required to establish the diagnosis.
The diagnosis of UCTD is based on the careful analysis of many factors. A thorough history and physical examination are essential for the diagnosis. There are certain laboratory studies that are helpful when considering the diagnosis of UCTD. However, it is important to know that the diagnosis cannot be made based on any one specific blood test. Often times, the evaluation includes X-rays of the chest and involved joints; CAT scans of the lungs, heart testing and evaluation for problems with the esophagus.
As mentioned above, people with UCTD may evolve into one of the more specific connective tissue diseases, such as lupus, Sjogren's, or scleroderma.

How is UCTD Managed?
It is important to recognize that there is no cure for UCTD. Therefore, early recognition and treatment of the disease is essential. In addition, because it is a chronic disease, people often require medical therapy for many years.
Before any specific therapy can be recommended, it is essential to establish the nature and extent of any organ damage. There are many medication options for people with UCTD. Most people require immunosuppressive medicines to control the inflammation and damage caused by the abnormal immune response. Some medicines that can be effective in treating UCTD include prednisone, hydroxychloroquine, methotrexate and azathioprine. Each of these medicines has its own side effect and toxicity profile. Each often requires regular blood testing and clinical monitoring to ensure safety.
Many people require treatment for gastroesophageal reflux disease, (GERD or "heartburn"), rashes, Raynaud's, eye diseases and heart and lung problems. All are part of the underlying disease.
In addition to medical therapy for UCTD, many people require physical therapy and rehabilitation. Under the guidance of rehabilitation therapists, people with UCTD learn how to appropriately rest, exercise and strengthen the various muscle groups and joints affected by UCTD.

What is the Role of National Jewish Health?
