See the list below:

  • Bronchiectasis and cor pulmonale complicate chronic/recurrent lower respiratory tract infections.

  • Hearing loss due to chronic otitis media or meningoencephalitis may affect as many as one third of patients with XLA.

  • The risk of GVHD is high in patients with SCID because of their inability to reject foreign antigens.

  • EBV-associated smooth muscle tumors may occur in patients who are partially reconstituted after bone marrow transplantation for SCID and who may not require surgery or chemotherapy. [29]

  • Central nervous system viral infection is one of the most potentially devastating complications of immunodeficiency, but this is a rare presentation in patients with SCID.
