Patterns of viral load changes in the early viral load substudy mirrored the patterns observed in the overall study.

If you have or suspect you may have a health problem, consult your health care provider. There were some significant differences in time to adverse events and regimen changes.

In the first place, an equivalence comparison is more stringent than the “non-inferiority” comparison commonly used in antiretroviral clinical trials. Please review our privacy policy. To conserve sample aliquots for additional atcg, samples were diluted 1: Find out the answers in this section.

Plasma HIV-1 RNA decline within the first two weeks of treatment is comparable for nevirapine, efavirenz, or both drugs combined and is not predictive of long-term virologic efficacy: Supporting sexual health and relationships for people with learning disabilities 18 December In relationships, sex and sexual health, people with disabilities often face We did not separately assess the relationship between week 4 virologic response and early or late virologic failure.

First-line ART – ACTG A Study

We found a smaller week 4 virologic response was associated with an increased risk for subsequent virologic failure. National Center for Biotechnology InformationU. From study entry onward, viral load assessments were performed centrally with the Roche Amplicor Monitor Assay Version 1.


There was also no significant difference in time to failure between efavirenz and ritonavir-boosted atazanavir, when paired with either of the two dual-nucleoside backbones. TheBody is designed for educational purposes only and is not engaged in rendering medical advice or professional services. Abacavir in Kivexa was associated with an increased risk of elevated lipids in the blood whether efavirenz or atazanavir-ritonavir was used.

Conclusions Within all treatment arms, a less robust week 4 virologic response was associated with higher risk for subsequent virologic failure.

Approval was obtained from each participating sites’ institutional review board for the main study and the substudy. Relationship of plasma HIV-1 RNA dynamics to baseline factors and virological responses to highly active antiretroviral therapy in adolescents aged years infected through high-risk behavior.

CollierMD, 5 Margaret A. HIV treatment outcomes continue to get better, says large analysis 27 December All people with HIV-2 should receive HIV treatment — without it, most will progress to AIDS and death 27 November Early HIV treatment reduces the risk of liver fibrosis 08 November Dolutegravir or lower-dose efavirenz equally effective, but less resistance with dolutegravir 01 November However, between-regimen differences in week 4 VL declines did not parallel the previously reported differences in longer term virologic efficacy in A, suggesting that between-regimen differences in responses were not due to intrinsic differences in antiviral activity.

See other articles in PMC that cite the published article. When participants’ regimens failed, people taking efavirenz-based regimens were likely to develop HIV that could resist the effect of efavirenz or nukes, compared to atazanavir-based regimens.

ACTG 5202 — Effectiveness of Different Treatments

Conclusions — Comparing Atazanavir and Efavirenz Here are some of the conclusions that the ACTG team arrived at when comparing atazanavir-ritonavir to efavirenz: In this section we have answered some qctg the questions you might have if you have just found out you have HIV. Our study results call into question the value of using early virologic response as a surrogate for expected longer term virologic outcome when comparing the efficacy of different regimens. Panel on Antiretroviral Guidelines for Adults and Adolescents.

The Data Safety Monitoring Board DSMB overseeing the study recommended that the nuke portions of the study be unblinded and participants then had the option of continuing to take their assigned nukes or changing them.
