Autonomic Neuropathy, Gastrointestinal Motility, and Inflammation in HIV
In Brief
A Early Phase 1 clinical trial evaluating Pyridostigmine for HIV Disease. Completed, enrolled 76 participants across 1 site.
Detailed Summary
The purpose of this study is to explore a possible link between the autonomic nervous system and immune function in patients with HIV. Sometimes HIV can cause these nerves to function abnormally, this is called HIV-associated autonomic neuropathy (HIV-AN). HIV-AN is a condition that is different from person to person. In some people it causes no symptoms and is not harmful, in others it may cause symptoms such as dizziness or lightheadedness, nausea, vomiting, diarrhea, constipation, or problems urinating. Most people with HIV-AN don't know that they have it. One of the important nerves in the autonomic nervous system is the vagus nerve. Abnormal function of the vagus nerve may cause stomach and intestinal slowing, which could lead to an overgrowth of bacteria. The body senses these bacteria and tries to fight them, leading to inflammation. In this study the researchers will test whether abnormal function of the vagus nerve in HIV is associated with stomach slowing and overgrowth of bacteria, and if a drug called pyridostigmine can help.
