Clinical Trial: Study of Mycobacterial Infections

Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Observational



Official Title: Natural History, Genetics, Phenotype and Treatment of Mycobacterial Infections

Brief Summary:

This study will examine the symptoms, course of disease and treatment of non-tuberculous mycobacterial (NTM) infections, as well as the genetics involved in these infections. Patients with NTM have recurrent lung infections and sometimes infections of the skin and other organs as well. They may also have curvature of the spine, barrel chest, and heart valve weakness. The study will compare the features of NTM with those of Job syndrome and cystic fibrosis, other diseases involving recurrent infections of the lungs and possibly other organs.

Patients with diagnosed or suspected non-tuberculous mycobacterial infection, cystic fibrosis or Job syndrome may be eligible for this study. All participants will have a medical and family history, blood and urine tests, imaging studies that may include X-rays, computed tomography (CT) or magnetic resonance imaging (MRI) scans, and DNA and other genetic studies. In addition, all patients with Job syndrome and cystic fibrosis, and patients with NTM who have lung disease undergo the following procedures:

  • Scoliosis survey X-rays of the spine to look for curvature or other abnormalities of the spinal column
  • Echocardiography imaging test that uses sound waves to examine the heart chambers and valves
  • Electrocardiogram measurement of the electrical activity of the heart
  • Pulmonary function tests breathing tests to measure how much air the patient can move into and out of the lungs
  • Body measurements measurements of height, weight, arm span, finger length, etc.
  • Joint function assessment of joint mobility using different maneuvers to test flexibility of joints and ligaments
