“Researchers at Yale and Boston University and their Russian collaborators have found that occasional heroin use by HIV-positive patients may be particularly harmful to the immune system and worsens HIV disease, compared to persistent or no heroin use.
The findings are published in the journal AIDS and Behavior.
“We expected that HIV-positive patients who abused heroin on an ongoing basis would have the greatest decreases in their CD4 count, but this preliminary study showed that those who abused heroin intermittently had lower CD4 cell counts, indicating a weakened immune system,” said lead author Dr. E. Jennifer Edelman, assistant professor of medicine at Yale School of Medicine. “Our findings suggest that heroin withdrawal may be particularly harmful to the immune system, as measured by CD4 cell count.”
