Correlation of intestinal structure and function in HIV infection.

The gastrointestinal tract has great importance in HIV infection because of its role as a primary barrier to the external environment and consequent need for effective immune function. Many factors promote the development of diarrhea in HIV-infected individuals. Understanding the genesis of the symptom is key to formulating effective therapy. Ultimate control of the problem depends on preventing HIV replication and immune depletion, as well as avoiding the development of opportunistic enteric infections in patients with severe immune deficiency.
