The introduction of novel agents to the therapeutic armamentarium for oncologic, rheumatologic, and neurologic disorders has resulted in major clinical advances. These agents impact immune function, resulting in a discrete spectrum of infectious complications. Purine analogues and alemtuzumab alter cell-mediated immunity, resulting in opportunistic viral/fungal infections. Herpes zoster incidence increases with bortezomib. Hepatitis B reactivation may occur with rituximab. Cases of progressive multifocal leukoencephalopathy have occurred following monoclonal antibody therapy. Tumor necrosis factor-α inhibitor therapy is complicated by tuberculosis reactivation and fungal infections. We summarize the impact of these therapies on pathogenesis and spectrum of infection complicating their usage.
