Our patient was tested for T cells, NK cells  and B cells (Figure 4).

Figure 4. Patient’s immune cell panel.

In SCID the body produces very few T cells and NK cells. B cells become defective in the absence of T cells. Most patients with X-SCID died before the age of 2 without treatment until universal screening identified those patients. Treating the patient with IgG allows the patients to usually live until adulthood. However, this patient also has mediastinal lymphadenopathy and a restrictive pulmonary function defect and has likely developed granulomatous and lymphocytic ILD (GLILD) as a complication of their X-SCID (3).

How is GLILD best treated? (Click on the correct answer to be directed to the sixth and final page)

  1. Rituximab
  2. Azathioprine
