Summary: Following the results of the START trial, guidelines that had previously set CD4 thresholds for treatment initiation were universally changed. This is likely to reduce mortality in people living with HIV who are diagnosed early and have immediate access to ART.
When should you start taking antiretroviral treatment for HIV?
A major international randomised clinical trial has found that people living with HIV have a considerably lower risk of developing AIDS or other serious illnesses if they start taking antiretroviral treatment (ART) sooner, when their CD4 cell count is above 500 cells/mm 3, instead of waiting until their CD4 cell count drops below 350 cells/mm 3.
What did the start study tell us about HIV treatment?
The Strategic Timing of AntiRetroviral Treatment (START) study, was a large-scale randomised clinical trial that tested whether earlier ART benefitted all people with HIV. Its predecessor, the SMART study, had a massive impact when it showed, in 2006, that staying on ART was better than interrupting it.
What are HIV and AIDS clinical trials?
HIV and AIDS clinical trials help researchers find better ways to prevent, detect, or treat HIV and AIDS. Examples of HIV and AIDS clinical trials underway include studies of new HIV medicines, studies of vaccines to prevent or treat HIV, and studies of medicines to treat infections related to HIV and AIDS.
Who develops the guidelines for HIV/AIDS treatment?
The federally approved medical practice guidelines for HIV/AIDS are developed by panels of experts in HIV care. More information about the panels can be found in each set of guidelines. The guidelines are available in multiple formats. The brief versions of the guidelines are compilations of the panels’ treatment recommendations and tables.
How has treatment for HIV changed over time?
Treatment of HIV has evolved from gruelling regimens with high pill burden, inconvenient dosing, treatment-limiting toxicities, food and drug interactions, incomplete viral suppression and emergence of drug resistance to manageable one or two pill once daily regimens that can be initiated in early HIV disease and ...
When was the first effective HIV treatment?
Zidovudine, commonly known as AZT, was introduced in 1987 as the first treatment for HIV. Scientists also developed treatments to reduce transmission during pregnancy.
Has there been any significant breakthroughs in the treatment of HIV?
While there is no practical and applicable cure for HIV on a large scale, there have been incredible strides in HIV treatment over the years that allow individuals to live a normal and healthy life.
What are the challenges of HIV treatment?
Treating HIV comes with several challenges and barriers, including a high cost of treatment, access to care, retention in care and transition from inpatient to outpatient care.
When did combination therapy start rising?
In 1995, a combination drug treatment known as the “AIDS cocktail” was introduced. This type of therapy was originally known as highly active antiretroviral therapy (HAART).

What is the main reason why single drug antiretroviral therapies eventually fail at controlling a patient's viral load?
Poor adherence leads to a low level of antiretroviral effect in the body, and this causes insufficient to suppress viral replication, finally resulting in treatment failure.
What is clinical trial?
In a clinical trial, a clearly defined outcome which is used to evaluate whether a treatment is working or not. Trials usually have a single primary endpoint (e.g. having an undetectable viral load) as well as a few secondary endpoints, covering other aspects of treatment safety, tolerability and efficacy.
When did START Data Safety and Monitoring Board stop randomised trials?
The START Data Safety and Monitoring Board (DSMB) stopped the randomised portion of the trial ahead of schedule in May 2015 when it determined that there was enough evidence to show a significant benefit of immediate treatment. All remaining untreated participants were offered the option to start therapy. They will continue to be followed for long-term outcomes, and a set of sub-studies is looking at specific manifestations including neurological function, artery function, bone density and liver disease.
What are the outcomes of the AIDS study?
The study measured a combination of outcomes that included serious AIDS events (such as AIDS-related cancer), serious non-AIDS events (major cardiovascular, renal and liver disease and cancer), and death.
How much is the risk reduction for AIDS?
This equates to a reduction of 53% in the risk of developing serious illness or death. Concerning AIDS-defining illnesses in particular, the risk reduction was even more pronounced at 70%.
How many cells are needed for HIV?
A major international randomised clinical trial has found that people living with HIV have a considerably lower risk of developing AIDS or other serious illnesses if they start taking antiretroviral treatment (ART) sooner, when their CD4 cell count is above 500 cells/ mm 3, instead of waiting until their CD4 cell count drops below 350 cells/mm 3.
How many people were in the START trial?
The trial enrolled 4685 men and women with HIV who had never taken ART. They were aged 18 and older, with a median age of 36, and their CD4 counts were all over 500 cells/mm 3.
What is START study?
The Strategic Timing of AntiRetroviral Treatment (START) study, was a large-scale randomised clinical trial that tested whether earlier ART benefitted all people with HIV. Its predecessor, the SMART study, had a massive impact when it showed, in 2006, that staying on ART was better than interrupting it. Like the previous study, START has been stopped early. Although it was expected to end in December 2016, an interim review of the study data by the study's Independent Data and Safety Monitoring Board (DSMB) recommended that results be released early.
How long did the participants in the ART study follow?
On average, participants in the study were followed for three years.
Does early treatment of HIV have a double benefit?
He added: “Moreover, early therapy conveys a double benefit , not only improving the health of individuals but at the same time, by lowering their viral load, reducing the risk they will transmit HIV to others. These findings have global implications for the treatment of HIV.”.
When will the AIDS epidemic end in NYS?
Integrates current evidence-based clinical recommendations into the healthcare-related implementation strategies of the NYS Ending the Epidemic initiative, which seeks to end the AIDS epidemic in NYS by the end of 2020.
When should rapid initiation be revisited?
If the patient understands the benefits of rapid initiation but declines ART, then initiation should be revisited as soon as possible.
What is ART therapy?
Antiretroviral therapy (ART) refers to the use of pharmacologic agents that have specific inhibitory effects on HIV replication. The use of fewer than three agents is not recommended for initiating rapid treatment. These agents belong to six distinct classes of drugs: the nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs, NtRTIs), the non-nucleoside reverse transcriptase inhibitors (NNRTIs), the protease inhibitors (PIs), the fusion inhibitors (FIs), the CCR5 co-receptor antagonists, and the integrase strand transfer inhibitors (INSTIs). See all commercially available antiretroviral drugs that are approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV/AIDS.
How many CD4 cells are needed for ART?
In START, a randomized trial initiating ART in treatment-naïve patients with CD4 counts >500 cells/mm 3 versus waiting for a decrease to ≤350 cells/mm 3 before initiation showed a 53% reduction in serious illness and death in the early ART group [Lundgren, et al. 2015]. Data from NA-ACCORD, a large observational cohort study, showed that both morbidity and mortality were improved by initiation of ART in patients with CD4 counts in the high or even normal range [Kitahata, et al. 2009]. A significantly decreased risk of death was observed in patients who initiated therapy at CD4 counts >500 cells/mm 3 compared to those who deferred to <500 cells/mm 3, as well as in the cohort that initiated ART in the 350 to 500 cells/mm 3 range compared with those deferring to <350 cells/mm 3 [Kitahata, et al. 2009]. Although other cohort studies demonstrated only a minimal survival advantage [Wright, et al. 2011] or no survival advantage among those starting ART at the highest CD4 counts, they did confirm the benefits of initiating ART at levels ≤500 cells/mm 3 [Cain, et al. 2011; CASCADE Collaboration 2011; Young, et al. 2012]. Another showed an approximately 33% reduction in the risk of death from end-stage liver disease, non-AIDS infections, and non-AIDS-defining cancers with every 100 cells/mm 3 increase in CD4 count [Marin, et al. 2009]. A randomized study of early versus deferred therapy in patients with CD4 counts in the 350-550 cells/mm 3 range showed no mortality benefit [Cohen, et al. 2011]; however, this study has significant limitations, most notably a relatively brief follow-up period.
What are the factors that interfere with successful adherence to treatment?
Identify and ameliorate factors that might interfere with successful adherence to treatment, including inadequate access to medication, inadequate supportive services, psychosocial factors, active substance use, or mental health disorders. (A2)
How long does it take to follow up on ART?
General Principles in Choosing a Regimen for Rapid ART Initiation. Follow up within 24 to 48 hours, by telephone or another preferred method, with a patient who has initiated ART to assess medication tolerance and adherence. If feasible, schedule an in-person visit for 7 days after ART initiation.
Is ART available in single dose?
Many ART combinations are now available in single-pill, fixed-dose combination formulations. Thus, the pill burden associated with early antiretroviral regimens has been largely eliminated. Nevertheless, lifelong adherence to medications may constitute a challenge to some, particularly when treatment with a single daily tablet is not feasible.
