Background:
Chronic granulomatous disease (CGD) is a genetic disorder of the phagocyte NADPH oxidase, which predisposes patients to infections and inflammatory complications, including severe colitis. Management of CGD colitis is a challenge because standard immunosuppressive therapy increases the risk of infection in already immunocompromised hosts.
Methods:
We report the use of infliximab in 5 patients with CGD.
Results:
Infliximab administration predisposed patients to severe infections with typical CGD pathogens but not mycobacteria, as reported with infliximab in other conditions. In addition to infections, infliximab administration led to successful closure of fistulae, sometimes with other untoward consequences. Infliximab-associated complications were associated with 2 deaths.
Conclusions:
Infliximab use in the treatment of CGD inflammatory bowel disease requires aggressive antimicrobial prophylaxis, assiduous surveillance for infection, and vigilance for untoward gastrointestinal complications. This experience suggests that infliximab therapy is effective but has untoward consequences in patients with CGD.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
