Current methods to assess kidney function have not been tested in people who have HIV/AIDS population. Given effects of the disease as well as potential effects of the medications, it is possible that the methods currently used to assess kidney function are not accurate. This purpose of this study is to evaluate methods to assess kidney function the HIV population. The investigators hypothesize that tenofovir causes a decrease in the secretion of creatinine which would cause an elevation in blood levels without affecting actual glomerular filtration rate (GFR).

Further study details as provided by Tufts Medical Center:

Primary Outcome Measures:
  • Performance of Glomerular Filtration Rate (GFR) Estimating Equations [ Time Frame: Blood samples for plasma iohexol clearance were taken at approximately 10, 30, 120, and 240 minutes post-iohexol dose. ]
    Overall bias, median difference (95% confidence interval), mL/min per 1.73 m^2, assessed as the median difference between the measured and estimated GFR across all estimated GFR levels, with positive values indicating an underestimation of measured GFR.

Biospecimen Retention:   Samples Without DNA
Whole and urine will be retained for future testing.

Enrollment: 206
Study Start Date: January 2009
Study Completion Date: June 2010
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
HIV Positive
Across-sectional analysis of 200 HIV+ patients with varying levels of kidney function

  Show Detailed Description


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Participants will be recruited from hospital based practices as well as from the community.

Inclusion Criteria:

  • Male or female 18 years of age or older
  • Confirmed HIV positive status
  • Treatment with stable antiretroviral medications for a period of at least 3 months prior to the study

Exclusion Criteria:

  • Persons less than 18 years of age. Children are excluded due to the fact that they are still growing. Growth causes levels of creatinine to change differently than in adults, thus requiring the use of age-specific GFR estimating equations.
  • Women who are either pregnant or who intend to become pregnant during the period of time in which the study visits will occur.
  • Allergy to any of the contrast media used or a known allergy to iodine or shellfish. Subjects who are not sure if they have an iodine allergy because they have not eaten shellfish nor have never received contrast dye will be excluded from participation.
  • Inability to cease taking medications that affect creatinine levels (e.g. trimethoprim containing medications, cimetidine) for one week prior to the study visit
  • Inability to maintain stable regimen of non-steroidal anti-inflammatory agents, angiotension converting enzyme inhibitors and or angiotension receptor blockers for one week prior to study visit.
  • Women who are breastfeeding
  • Current treatment with amiodarone
  • Current treatment with metformin
  • Acute exacerbation of asthma or chronic obstructive lung disease in the past three months requiring hospitalization or oral steroid therapy
  • Inadequate venous access
  • People with kidney failure (currently undergoing or having received peritoneal dialysis or hemodialysis treatment within the past three months or estimated GFR (eGFR) < 15 ml/min per 1.73 m2)
  • End stage conditions such as cirrhosis
  • Active treatment for cancer
  • Progressive neurological diseases
  • Severe gastric immotility
  • History of cognitive or physical impairments that will not allow completion of the study
  • Inability to provide informed consent
