Central nervous system tuberculosis reactivation following intravenous iron supplementation.

Patients with inflammatory bowel disease (IBD) are often treated with tumor necrosis factor (TNF)-alpha inhibitors and are therefore at higher risk for tuberculosis (TB) reactivation. IBD patients also frequently have iron deficiency which is often treated with intravenous iron supplementation. Iron plays an important role in mycobacterial infections, and reactivation of TB has been rarely reported after iron repletion.
