The importance of virological control in functional immune reconstitution was investigated in HIV-1 infected patients who maintained high or undetectable plasma HIV RNA levels over 2\u20134\u2003years on HAART (discordant and complete responders, respectively). Immunocompetance and immune activation were assessed directly ex vivo and after a short period of culture, as HIV replication in cultures from viraemic patients may artificially depress responses. Expression of cytokine (interferon-\u03b3, interleukin-5) and chemokine receptor (CCR5, CRTH2) mRNA were determined and soluble CD30 and NO2\u2013\/NO3\u2013 were measured in sera. Unstimulated cells from all patients had low levels of IFN\u03b3 mRNA relative to uninfected controls. Discordant responders had more IFN\u03b3, IL-5 and CCR5 mRNA in mitogen-stimulated PBMC than complete responders, where the difference could be attributed to CD8-T-cells. Serum NO2\u2013\/NO3\u2013 levels were significantly higher in all patients than controls, with no difference between complete and discordant responders. Serum CD30 levels were significantly higher in discordant responders. These data indicate a persistent immune deficit in immune reconstituted patients irrespective of HIV viral load and associate persistent viral replication with lymphocyte activation, probably involving CD8 T-cells.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2004.02589.x","type":"journal-article","created":{"date-parts":[[2004,9,16]],"date-time":"2004-09-16T13:49:46Z","timestamp":1095342586000},"page":"110-115","source":"Crossref","is-referenced-by-count":3,"title":["Persistent
