NCT02850276

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Change in Breath Test

    Breath Test at week 8 as compared to baseline. Breath test results is the rise in the combined hydrogen and methane during the breath test.

    baseline and week 8

  • Number of Participants With Reduction in Small Intestinal Bacterial Overgrowth (SIBO)

    Number of participants with reduction in Small intestinal bacterial overgrowth (SIBO) assessed with breath testing after 8 weeks of treatment. The hydrogen breath test for the detection of small intestinal bacterial overgrowth (SIBO), obtained by having participants exhale into a plastic bag. the hydrogen content of the samples is measured using a commercially available analyzer.

    week 8

Secondary Outcomes (6)

  • Mean Percent Retention of Gastric Contents on Gastric Emptying Study

    Baseline and week 8

  • Change in sCD14 Level

    Baseline and week 8

  • Change in TNFα Level

    Baseline and week 8

  • Change in IL-6 Plasma Level

    Baseline and week 8

  • The Composite Autonomic Symptom Score (COMPASS)

    Baseline and week 8

  • +1 more secondary outcomes

Study Arms (1)

Pyridostigmine

EXPERIMENTAL

30mg PO three times a day

Drug: Pyridostigmine

Interventions

Also known as: Pyridostigmine Bromide, Mestinon, Regonol, Gravitor

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥18 years old
  • Documented evidence of HIV-1 infection
  • Stable CART therapy for ≥3 months Most recent HIV-1 viral load ≤100 copies/ml (value must be within the past six months)
  • English speaking
  • Able to tolerate autonomic testing (e.g. able to stand, able to perform Valsalva maneuver).
  • If using nicotine-containing products willing to refrain from use for 24 hours prior to all testing procedures (autonomic reflex screen, breath testing, and gastric emptying)
  • ≥1 GI symptom on the Survey of Autonomic Symptoms (SAS)47

You may not qualify if:

  • Diagnosis known to cause autonomic dysfunction other than HIV (e.g. Parkinson's disease, diabetes)
  • Diagnosis known to cause GI dysfunction other than HIV (e.g. peptic ulcer disease, infectious diarrhea)
  • Current use of any of the following classes of medications (due to potential for significant autonomic or GI effects, interaction with pyridostigmine, or interference with one or more of the testing procedures) Prokinetics (e.g. metoclopramide) Anti-diarrheals (e.g. loperamide) Antibiotics Mefloquine
  • Medical or psychiatric conditions precluding safe participation in study procedures or deemed likely to result in hospitalization during the study period.
  • The presence of one or more of the following diagnoses which render the Valsalva maneuver relatively or absolutely contraindicated: uncontrolled glaucoma, aortic stenosis, myocardial infarction in the last 6 months, other retinopathy or unclipped cerebral aneurysm.
  • The presence of one or more of the following diagnoses which impede interpretation of autonomic testing: cardiac arrhythmias or pacemakers.
  • An allergy to eggs (contraindication to gastric emptying scintigraphy)
  • Any of the following laboratory results:
  • Positive pregnancy test (administered to women of childbearing potential only) Urine toxicology screen positive for stimulants (e.g. amphetamines, cocaine) or opiates/opioids.
