Hypothesis

Does high dosage intravenous immunoglobulin (IVIG) treatment have a long-term effect on residual viremia and T-lymphocyte activation in HIV-infected patients on effective antiretroviral therapy?

Conclusion

The decrease in the latent HIV-1 pool observed during IVIG treatment is transient, with residual viremia rebounding to pre-treatment levels after 48-104 weeks.

Supporting Evidence

  • Plasma residual viremia rebounded to pre-treatment levels after IVIG treatment.
  • Six out of nine patients had detectable levels of plasma HIV-RNA at follow-up.
  • A correlation between plasma HIV-1 RNA and CD4+ T-cell count was found.

Takeaway

This study looked at how a treatment called IVIG affects the amount of HIV in the blood. It found that while the treatment worked for a little while, the HIV levels went back up after some time.

Methodology

Nine HIV-infected subjects on effective ART were evaluated 48-104 weeks after IVIG treatment, along with 14 HIV-infected controls on suppressive ART. Plasma HIV-1 RNA was analyzed using an ultrasensitive PCR method.

Potential Biases

The study did not mention specific risks of bias.

Limitations

The study had a small sample size and was not powered for detection of existing possible correlations.

Participant Demographics

Participants included 9 HIV-infected subjects on effective ART and 14 HIV-infected controls, with a mix of ages and genders.
