Miami Selenium for heart & immune health trial
DOI 10.1186/ISRCTN22553118
ClinicalTrials.gov identifier
EudraCT number
Public title Miami Selenium for heart & immune health trial
Scientific title
Acronym MIASEL
Serial number at source RO1 DA13128
Study hypothesis The primary aim of this project is to examine whether selenium supplementation in cocaine-abusing and non-substance-abusing Human Immunodeficiency Virus (HIV) infected persons will diminish oxidative stress and improve immune function, insulin sensitivity, cardiac and vascular function, and indices of Cardiovascular Disease (CVD) risk. The secondary aim of this project is to determine whether oxidative stress, insulin sensitivity, and immune and cardiovascular function are potential mediating mechanisms for selenium effects on the measures of CVD risk.

Study design Two group randomised double-blind placebo-controlled study
Countries of recruitment United States of America
Disease/condition/study domain Human Immunodeficiency Virus (HIV)
Participants - inclusion criteria 1. Participants provided informed consent
2. Presented documented evidence of their HIV-1 infection
3. Were 18 to 55 years of age
4. Were not being treated pharmacologically for a diagnosed cardiovascular condition (e.g., beta-blockers, calcium antagonists, Angiotensin-Converting Enzyme [ACE] inhibitors), for carbohydrate conditions (e.g., hypoglycemics, insulin sensitizers), for psychiatric conditions (e.g., antipsychotics, antidepressives), and for endocrine conditions (e.g., estrogen hormonal replacement)
5. Presented no evidence of myocardial infarction or Atrio-Ventricular (AV) conduction arrhythmias upon electrocardiogram
6. Had no history of diabetes or cardiovascular disorder, or other major systemic diagnosis unrelated to HIV spectrum disease
7. Had no gross neurocognitive dysfunction indicated by a Folstein Mini-Mental Status Exam (MMSE) score < 26
8. Did not have a recent acute infection or surgery within three months of study entry
9. Were premenopausal and not pregnant with no intent to become pregnant
10. Were not participating in another blinded clinical trial
11. Refused to discontinue use of a nutritive supplement that contained > 50 ug per pill
12. Had a serum selenium level upon screen equal or superior to 75 ug/l.

Participants meeting these criteria signed an informed consent form for screening and if still eligible additional written consent was obtained for randomization into the trial.
Participants - exclusion criteria 1. Participating in another blinded clinical trial
2. Being treated pharmacologically (e.g., beta-blockers, calcium antagonists, ace inhibitors) for diagnosed cardiovascular function
3. Pregnant or have the intent to become pregnant
4. Post-menopausal women
5. Presenting an electrocardiogram (ECG) arrhythmia in which the proposed cardiovascular assessments would be contraindicated
6. Taking any medications that have contraindicating cardiovascular effects (i.e., tricyclic anti-depressant medications, etc.)
7. Displaying gross neurocognitive dysfunction indicated by a Folstein Mini-Mental Status Exam (MMSE) score equal or superior to 26
