Poly-functional immune response in HIV infection: a correlation between immunological and clinical status

Aim: We analysed patient immunological status and serum cytokine profile to establish immune-activation state and afterwards the obtained data were correlated to viral activity and ARV therapy. Materials and Methods: 50 HIV-1 mono-infected patients (pt) were recruited: 5 naïve, 5 virologic controllers, 10 virologic non controllers (ARV drug-untreated pt with HIV viremia above 10,000 copies/ml), 20 virologic responders (ARV drug-treated pt with undetectable HIV viremia) and 10 virologic non responders patients (ARV drug-treated pt with HIV viremia ≥ 400 copies/ml). IFN- production and plasmatic cytokine pattern levels (IL-1β, IL-2, IL-6, TNF-β, IL-4, IL-10, IL-13, IP-10, IL-8, MIP-1 α, MIP-…
