Disorders of the Colon and Rectum

Part of the Clinical Gastroenterology book series (CG)


The specific aim of this chapter is to explore the various viral, bacterial, parasitic, and fungal organisms that can lead to colorectal disease processes in people living with HIV/AIDS (PLWH). Many of these diseases are fairly uncommon in the immunocompetent population but start to show their force in those who cannot mount a robust immune response. We will explore the mechanisms of these infections with specific focus on clinical methods of diagnosis, endoscopic findings, and the specific treatment regimens available to curtail the state of illness. One of the predominant presenting symptoms with all of these organisms is diarrhea, and thus, prior to elaborating on these organisms, we must first understand the approach necessary to take when assessing a patient with this complaint.
