Antiretroviral therapy in HIV-infected elite controllers: impact on gut immunology, microbial translocation, and biomarkers of serious non-AIDS conditions.


PMID 25393939

Abstract

Elite controllers (ECs) maintain undetectable HIV viral loads without antiretroviral therapy (ART) but are at increased risk of serious non-AIDS conditions (SNA). We assessed the impact of ART in ECs on gut immune dysfunction and biomarkers predicting SNA (blood CD4/CD8 ratio, plasma IL-6, D-dimer levels). At baseline, ECs had elevated IL-6 and D-dimer levels and reduced CD4/CD8 ratio compared with HIV-uninfected controls, but no difference in microbial translocation or gut CD4 subsets. ART increased CD4/CD8 ratio but did not normalize IL-6 and D-dimer levels. EC SNA pathogenesis may be independent of gut immune dysfunction, and resolution may require prolonged ART.
