  • Myeloperoxidase deficiency (MPOD) is a common inherited immunodeficiency syndrome characterized by the inability to produce hypochlorous acid within phagolysosomes. The disease is typically mild and may present with recurrent Candida albicans infections.

  • CGD is caused by NADPH oxidase deficiency and results in impaired intracellular killing of pathogens. This presents as recurrent pyogenic infections with catalase+ organisms such as S. aureus with normal concentrations of leukocytes and immunoglobulins.
