Immunocompromised Host • DEFINITION These patients are defined by their susceptibility to infection with organisms of low native virulence for the immunologically normal hosts.
Immunocompromised Host Spectrum of immunocompromised hosts has expanded with prolonged survival of • solid organ and hematopoietic transplant recipients • congenital immune deficits and autoimmune disorders • epidemic of human immunodeficiency syndrome/acquired immunodeficiency syndrome (HIV/AIDS).
Immunocompromised Host • RISK FACTOR: Immunosuppressive therapies create a diverse set of immune deficits that create the substrate for opportunistic infections.
