Such a reduction of just 1 or 2% may seem insignificant at first purchase ivermectin 3mg on-line antimicrobial keyboards and mice. The best data for this patient goup come from HTPN-052 proven ivermectin 3mg antibiotic resistance new zealand, a trial with 1,763 HIV-discordant couples in the US, Africa and Asia. The requirements were that HIV+ partners were treatment-naïve with CD4 170 ART T cells between 350 and 550/µl. They were then randomized for ART, either imme- diately or in a rather late stage when CD4 T cells reached below 250/µl or even after manifestation of AIDS (Cohen 2011, Grinsztejn 2014). Although the trial’s primary endpoint was HIV transmission, preliminary results showed that the numbers of severe diseases and death were significantly lower in the group starting ART imme- diately (57 versus 77, p=0. With regard to AIDS cases, the difference was signif- icant (40 versus 61, p=0. However, a major reason for this difference was caused by extrapulmonary tuberculosis (3 versus 17), which, at 55%, was most frequently observed in India. Asymptomatic patients, >500 CD4 cells/μl: START Study Large but very complex cohort studies have yielded conflicting results with regard to the benefits of starting ART in patients at high CD4 T cell ranges. Whereas in the US early treatment was of clinical benefit (Kitahata 2009), this was not observed in Europe (Sterne 2009). It seems obvious, that the hitherto largest trial, the START study, will end this debate (START 2015). In this study, worldwide 4,685 patients with more than 500 CD4 T cells/µl (median 651/µl, median viral load 12,759 copies/ml) were randomized to initiate ART immediately or to wait until CD4 T cells declined to below 350 CD4 cells/µl or until symptoms appeared. The ART regimen was chosen by the treating physician. The primary composite end point was any serious AIDS-related event, serious non-AIDS-related event, or death from any cause. In May 2015, the data and safety monitoring board recommended that patients in the deferred-initiation group be offered antiretroviral therapy. In the immediate ini- tiation group the composite primary end point was reached in significantly fewer patients than in the deferred initiation group (42 versus 96 events, p <0. However, the beneficial effect of immediate ART was evident also for serious non–AIDS-related events, and no increased rate of adverse effects associ- ated with this strategy was observed. There was no evidence that the beneficial effect differed according to age, sex, race, region of the world, CD4 T cell count, viral load, or risk factors for serious non-AIDS diseases. According to the authors, these results indicate that ART should be recommended for all HIV+ patients regardless of the CD4 T cell count. It remains to be seen if there will be small patient group (very high CD4 T cells, very low plasma viremia) for whom ART will not be recommended. When to start ART 171 Late Presenters: AIDS and/or <350 CD4 T cells/μl Although treatment possibilities have dramatically improved, many patients still present at a very late stage of infection. Questions about beginning an optimal therapy are superfluous as these patients are more or less classified as urgent. There is no consensus regarding the definition of “late presenter”. In most cases, a CD4- cell count below 200/µl and/or a manifest AIDS disease at the time of HIV diagno- sis will do. Some authors also classify the groups “late testers”, “very late presenters” and even “long-term non-presenters”. At the second “HIV in Europe” conference in November 2009, it was agreed that those patients with a CD4 cell count below 350/µl at initial presentation are to be referred to as late presenters (Antinori 2011). In the US and Europe they still constitute more than half of all patients (Althoff 2011, Mocroft 2013). Incidence and risk factors of a late HIV diagnosis How frequent are late presenters? In COHERE, a collaboration of observational HIV cohorts in Europe, among 84,524 individuals from 23 cohorts in 35 countries, 53. Lacking an overall valid definition, rates between 10-44% are currently being reported in different European countries and the US with a recently slightly downward trend (Table 5. Several studies have looked at the risk factors of late diagnosis (Table 5. The characteristics (advanced age, migrant origin, heterosexual transmission, see above) indicate more complex reasons for a late diagnosis. They probably involve patients (less access to health system, lack of information, fear of stigmatization), as well as doctors and members of the health care system (among others lack of HIV awareness with certain patient groups).
