HIV treatment use increases in the US

Between 2000 and 2008, the proportion of HIV-infected patients in the U.S. receiving effective treatment known as highly active antiretroviral therapy (HAART) increased, and HIV-infected patients appeared to be less infectious and have healthier immune systems at death, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. The study was nested in the NA-ACCORD (North American AIDS Cohort Collaboration on Research and Design), which is the largest cohort of HIV-infected adults in North America. The findings are published in the September 4 edition of Annals of Internal Medicine.

The study included more than 45,000 HIV-infected participants receiving clinical care for HIV. The study population was demographically similar to the U.S. population living with HIV, according to national surveillance data from the Centers for Disease Control and Prevention. Over the study period, the researchers found that the proportion of HIV-infected participants prescribed HAART increased 9 percentage points to 83 percent. During this time, the researchers also observed an increase in viral load suppression among those with HIV, regardless of treatment. Suppression of viral load reduces the likelihood of transmitting HIV to others. Among those taking HAART, the proportion with a suppressed viral load increased from 54 percent to 81 percent.

"This is good news for the HIV epidemic in the U.S., but there is room for improvement," said Keri N. Althoff, PhD, MPH, lead author of the study and assistant professor in the Bloomberg School's Department of Epidemiology. "We need to continue to focus on linking HIV-infected adults into care and effective treatment, not only for the individual's health, but to reduce the likelihood of transmission to others."

The analysis also found an increase in median CD4 count for participants who died from HIV during the study period. Median counts increased at the time of death from 60 cells/mm3 to 209 cells/mm3. A higher CD4 count suggests a healthier immune system. Additional research is planned to investigate trends in the causes of death.

"Our study demonstrates the data from the NA-ACCORD can be used to monitor important health indicators among adults with HIV, which is needed to evaluate the impact of the Affordable Care Act and to measure progress towards the National HIV Strategy goals," said Althoff.
