Gastrointestinal Tract

Cryptosporidiosis — This is a parasite that can cause chronic diarrhea. Other symptoms include stomach cramps, nausea, fatigue, weight loss, appetite loss, vomiting and dehydration. This infection is difficult to treat and there is no definitively effective treatment. Symptom control and treatment of HIV are necessary.
Cytomegalovirus — Although this virus can affect the entire body, it commonly occurs in the stomach, causing fever, diarrhea and stomach pain. It most likely occurs when the CD4+ T cell count falls below 50 cells per cubic millimeter of blood.
Mycobacterium Avium Complex — This is a bacterial infection that can cause persistent fever, night sweats, fatigue, weight loss, anemia, abdominal pain, dizziness, diarrhea and weakness. The bacteria that cause this infection is found in water, dust, soil and bird droppings. This disease most likely occurs when the CD4+T cell count falls below 50 cells per cubic millimeter of blood. Preventive treatment, usually with azithromycin, is administered when CD4+ T cells are less than 50 cells per cubic millimeter of blood.
