  Purpose
In HIV patients, fasting insulin levels decrease with chromium supplementation. This study is to determine if chromium nicotinate supplementation at 400ug/day for 16 weeks will improve insulin resistance in HIV patients with metabolic abnormalities.

Condition Intervention Phase
HIV Infections Drug: chromium nicotinate Drug: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: The Effects of Chromium Supplementation on Glucose and Lipid Metabolism in Patients With HIV Infection

Primary Outcome Measures:
  • insulin resistance calculated using fasting glucose and fasting insulin levels in blood [ Time Frame: BL & 16 weeks ]
    HOMA-IR


Secondary Outcome Measures:
  • hemoglobin A1c (HbA1c) [ Time Frame: BL & 16 weeks ]
  • blood lipid profile (triglycerides [TG], cholesterol or high-density lipoprotein [HDL]) [ Time Frame: BL & 16 weeks ]
  • body composition by dual energy x-ray absorptiometry (DEXA) scan, bioelectric impedance analysis and skin fold measurement [ Time Frame: BL & 16 weeks ]
  • oxidative stress [ Time Frame: BL & 16 weeks ]
  • plasma chromium [ Time Frame: BL & 16 weeks ]

Enrollment: 52
Study Start Date: August 2002
Study Completion Date: February 2008
Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Chromium
400 μg (200 μg pills, twice per day) of Cr-nicotinate
Drug: chromium nicotinate
Placebo Comparator: Placebo
Identical looking placebo (di-calcium phosphate)
Drug: Placebo

Detailed Description:
This study is a randomized, double-blind, placebo-controlled, crossover study where patients will be supplemented for 16 weeks with either chromium nicotinate 400 ug/day or placebo and then crossover to the opposite treatment for another 16 weeks. Each soft gel capsule of chromium contains 200ug of chromium and patients will take 1 capsule twice a day or its placebo. Placebo contains di-calcium phosphate in a soft gel capsule and its appearance is similar to the chromium capsules.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • HIV documented patients will be considered for the study if they have at least one abnormality with respect to fasting blood glucose, TG, total or HDL cholesterol. Normal fasting glucose is defined as < 6.1 mmol/L. Hypertriglyceridemia is defined as concentrations above 2.0 mmol/L on the basis of reports of increased risk of cardiac disease. Hypercholesterolemia is defined as concentrations above 5.5 mmol/L and a low HDL-cholesterol concentration as less than 0.9 mmol/L.
  • Patients will need to be on a stable drug regimen for at least 8 weeks and not taking any chromium supplement or chromium-containing multivitamins 4 weeks prior to and during the study period. Patients can stay on their hypoglycemic or lipid-lowering medications and the required dosage will be monitored.

Exclusion Criteria:

  • Patients will be excluded if there is concomitant acute infection or malignancy.
