PPT-The Immune System and the Immunocompromised Patient

Chapter 4 Introduction Molecules recognized as nonself are antigens Several mechanisms to protect itself First level of protection include physical and biochemicalskin acid in stomach Second level of protection phagocytic cells enzymes and proteins. Chapter 40. Agents of Disease. The human body provides a suitable environment for many microorganisms: it is moist, warm and full of nutrients.. Not all microorganisms are harmful; some are beneficial. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSES AGAINST INFECTION INCLUDE THE. SKIN. MUCOUS MEMBRANES. PHAGOCYTIC CELLS. ANTIMICROBIAL PROTEINS. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSE MEANS THAT THEY DON’T DISTINGUISH BETWEEN MICROBES. Solutions to improve treatment. Current . immunosuppressors. …. …suppress the entire immune system, leaving patients more vulnerable to everyday infections and higher rates of cancer.. However, this is necessary because the immune system attacks parts of the body which are work well and are needed (in MS, myelin is targeted, causing demyelination) but we cannot isolate the suppression to just one impact of the immune system so to protect the targeted area we must lower the guard of everywhere else. .  Immunocompromised. An Immunocompromised host is a patient who does not have the ability to respond normally to an infection due to an impaired or weekend immune system. . This inability to fight infection can be caused by a number of conditions including:. an antigen . to stimulate the immune response through active . immunity.
