HIV Clinical Trial
— CMExOfficial title:
Soluble Insulin Receptor Dysfunction Correlates With HAND in HIV+ Women on CART
The study evaluates the association between soluble insulin receptor dysfunction, cardiorespiratory fitness, and HIV associated neurocognitive disorder (HAND). Those who volunteer to participate in the study will have two evaluations at study entry that include a dual x-ray absorptiometry (DEXA) densitometry, anthropometry, neurocognitive testing, blood and urine samples for metabolic testing, and a cardiorespiratory fitness testing. DEXA will be conducted in the Endocrinology Unit at the University Hospital, Medical Center (letter of support included). The cardiorespiratory fitness testing will be conducted in the AIDS Clinical Trials Unit (ACTU) project, University of Puerto Rico, Medical Sciences Campus, and the Puerto Rico Clinical and Translational Research Consortium. Then, participants will be invited to participate in a 6-week, 3 days/week individualized exercise program. The exercise program will be conducted at the University of Puerto Rico Medical Sciences Campus. After completion of the exercise program, study entry evaluations will be repeated. The duration of the study will take approximately 10 weeks.

Eligibility |
Inclusion Criteria: 1. HIV-seropositive women =21 years with lymphocytes differentiated cells 4 (CD4) cell count or nadir in the last year =500 cells/mm3, or viral load =1,000 copies/mL despite highly active antiretroviral therapy (HAART). 2. Education level =9th grade, since is the minimum required for some of the neuro-psychological (NP) tests. All HIV-seropositive and HIV-seronegative participants will be tested for vocabulary and reading pre-morbid cognitive function as described below. 3. Non-drug abusers; defined as those with <5 exposures in a lifetime to drugs (opiates/heroin, methamphetamine, cocaine/crack, speed ball). For the purpose of this study neither tobacco nor nicotine use will be considered a drug. 4. No diagnosis of diabetes or the use of hypoglycemic agents. Exclusion Criteria: 1. HIV+ women and men <21 years old with CD4 cell count >500 cells/mm3 and/or viral load <1,000 copies/mL. 2. Opportunistic infections of the central nervous system (CNS) as determined by neurological evaluation and neuroimaging. (Neuroimaging studies, if needed, will be performed as part of patient care and hence have not been included as a budget item in this proposal.) 3. History of diabetes or the use hypoglycemic agents. 4. Underlying neurologic and/or neuropsychiatric disorders such as cerebrovascular events; history of meningitis/encephalitis, CNS opportunistic infections, or seizures; head trauma (<6 months with loss of consciousness for >1 hr); cerebral palsy; or any other neuropsychiatric condition that in the judgment of the investigators may affect the study. 5. Active systemic infection or illness, which in the judgment of the investigators may affect the study. 6. Pregnant/nursing mothers or women with recent birth (<60 days). 7. Substance abuse: active drug use - all participants will be screened with urine toxicology and active alcohol abuse - those scoring >3 points in the Michigan Alcoholism Screening Test (MAST) will be screened with blood samples for alcohol levels (Seltzer 1975). 8. Patients who are unwilling to give informed consent or incapable of understanding informed consent. 9. Education less than 9th grade. |

Primary | Cardio-respiratory fitness as measured by maximal oxygen consumption (VO2max) | Maximal oxygen consumption | 6 weeks | No |
Secondary | Metabolic syndrome classification based on the National Cholesterol Education Program (NCEP) criteria | Number of participants with abnormal values in 3 or more of the following: fasting glucose, resting blood pressure, waist circumference, fasting triglycerides, and HDL. | 6 weeks | No |
Secondary | Neurocognitive function as measured by memory testing | Number of participants with abnormal values of neurocognitive function will be identified. Measures of memory testing using questionnaires and a computer-based assessment will be aggregated to arrive at one reported value of neurocognitive function. | 6 weeks | No |
