Primary Outcome Measures:
  • Evaluation of ARFI velocity in HIV patients [ Time Frame: 2 years ]
    Measurement of ARFI velocity is non-invsive ultrasonographic technique. It is performed with a abdominal convex probe which is same probe as conventional ultrasonography. Short-duration acoustic radiation forces result in shear-wave propagation away from the region of excitation and are tracked using ultrasonic correlation-based methods. This results are called ARFI velocity which is expressed as meters per second

Estimated Enrollment: 100
Study Start Date: October 2010
Estimated Study Completion Date: June 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
HIV patients with normal liver status
HIV patients without abnormal liver function and chronic liver disease
Device: Acoustic radiation force impulse imaging
Acoustic radiation force impulse (ARFI) imaging were measured 10 times in each patient.The region of interest was chosen in an area where the normal liver parenchyma was at least 6 cm thick and free of large blood vessels was chosen. A measurement depth of 2 cm below the liver capsule was chosen to standardize the examination.
Other Name: ARFI imaging

Detailed Description:
HIV positive patients who have liver dysfunction have shown to be correlated with high mortality and morbidity. To date, ARFI elastography has been known to correlate with the degree of liver fibrosis in chronic liver disease. However, ARFI velocity has not yet been reported in HIV patients. The aim of this study was to identify the normal range of ARFI velocity and liver stiffness value by recruiting HIV patients without abnormal liver function and chronic liver disease.
