Hypothesis
Breast milk contains CD4+ T cells able to spontaneously produce HIV-1 proteins and RNA.
Conclusion
Activated CD4+ T cells producing HIV-1 are found in breast milk, suggesting a potential source of HIV-1 transmission despite antiretroviral therapy.
Supporting Evidence
- All 15 women had detectable spontaneous HIV-1 antigen secreting cells in breast milk.
- Median HIV-1 RNA levels were similar in breast milk from aviremic and viremic women.
- Breast milk CD4+ T cells predominantly expressed activation markers.
Takeaway
Moms with HIV can have special cells in their breast milk that make the virus, which can still get to babies even if the mom is on medicine.
Methodology
The study measured HIV-1 antigen and RNA production in CD4+ T cells from blood and breast milk samples of HIV-1 infected women.
Potential Biases
Potential bias in participant selection and reporting of HIV-1 RNA levels.
Limitations
The study may not fully represent the complex dynamics of HIV-1 transmission through breastfeeding.
Participant Demographics
15 HIV-1 infected lactating women, with varying antiretroviral treatment statuses.
