When should HIV art be initiated?
ART should be initiated as soon as possible after HIV diagnosis (AII). When initiating ART, it is important to educate patients about the goals and benefits of ART and to identify and address barriers to care engagement and treatment adherence (AIII). Patients should also understand that currently available ART does not cure HIV.
What is antiretroviral therapy (ART) for HIV?
Antiretroviral therapy (ART) involves using two or more antiretroviral drugs to suppress the virus to undetectable levels in the blood. This treatment can slow the progression of the disease to a point at which you can live a long, healthy life. 4
What is the history of HIV treatment?
The development of research, treatment, and prevention. Azidothymidine, also known as zidovudine, was introduced in 1987 as the first treatment for HIV. Scientists also developed treatments to reduce mother to child transmission. In 1997, highly active antiretroviral therapy (HAART) became the new treatment standard.
Does art reduce HIV transmission in the community?
Modeling evidence suggests the potential for rapid ART initiation to significantly reduce HIV transmission in the community, although this has been directly modeled only in the context of South Africa [Granich, et al. 2009].
When was AIDS discovered?
In 1983 , scientists discovered the virus that causes AIDS. They later named it human immunodeficiency virus (HIV). The race was on for a treatment to stop this deadly disease.
What drug stopped HIV from multiplying?
Also called azidothymidine (AZT), the medication became available in 1987.
What is the name of the drug that is used to treat HIV/AIDS?
These drugs paved the way to a new era of combination therapy for HIV/AIDS. Doctors began prescribing saquinavir plus AZT or other antiretrovirals. This combination therapy was dubbed highly active antiretroviral therapy (HAART). That approach became the new standard of care for HIV in 1996. HAART greatly lengthened the life span of people with AIDS.
What is the name of the drug that shuts down HIV?
Similar to AZT, NNRTIs shut down HIV by targeting the enzymes it needs to multiply. These drugs paved the way to a new era of combination therapy for HIV/AIDS.
How many HIV medications are there?
Today, more than 30 HIV medications are available. Many people are able to control their HIV with just one pill a day. Early treatment with antiretrovirals can prevent HIV-positive people from getting AIDS and the diseases it causes, like cancer.
How long does it take for AZT to be approved?
The FDA approved AZT in less than 4 months, fast-tracking a process that usually takes many years. It treats HIV, but it isn’t a cure.
What disease did gay men get?
Others were coming down with a rare type of pneumonia. A year later, the mysterious disease had a name: acquired immune deficiency syndrome, or AIDS.
What was the first drug to be used for HIV?
The initial years were characterized by treatment failures and disappointments [5]. However, by 1985, a diagnostic antibody test was developed [6] and clinical trials began with direct acting dideoxynucleoside reverse transcriptase inhibitors (NRTIs), the first being azidothymidine (AZT) [7,8]. By 1987, treatment with AZT was found associated with a greater survival at 24 weeks [9], but this benefit was short-lived; by 48 weeks, survival benefits were no longer observed [10–14]. Despite its limitations and side effects, AZT, later called zidovudine (ZDV), was approved in 1987 for use in patients with advanced HIV. In short succession, three other NRTIs were approved for use in HIV-1 infection: zalcitabine (ddC), didanosine (ddI) and stavudine (d4T). Each had its own particular toxicities and none is widely used today. To avoid the toxicity profiles, attempts were made to administer drugs sequentially and to alternate therapies [15]. These approaches were not very effective and, clinically, patients continued to fare poorly except for a reduction in some of the rates of adverse reactions.
What is the next advance in HIV therapy?
The next advance in HIV therapeutics came with the development of drugs from different classes: non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors, both classes having a direct effect on HIV.
How many people are eligible for antiretroviral therapy?
antiretroviral therapy, which not only improves the health and well being of people living with HIV but also stops further HIV transmission, was available for 6.65 million people in low and middle-income countries. This number accounts for 47% of the 14.2 million people eligible ( Fig. 1 );
What was the impact of triple therapy?
The result was a consequence of not only the availability of new drugs from different classes but also of: the understanding that HIV infection, even during the clinically latent phases of the disease, is characterized by an important viral turnover with continuous high-level virus replication [25–28]; the demonstration that measured concentration of HIV in plasma (the ‘viral load’) was predictive of the subsequent risk of disease progression and death [29]; and the elucidation of the molecular, functional and clinical impact of drug resistance to antiretroviral drugs [30,31]. All these advancements supported the critical need to fully suppress HIV replication in order to stop virus mutation. It also highlighted the essential need to monitor treatment by measuring plasma HIV load [32].
When was Indinavir approved?
Indinavir is a protease inhibitor, approved in 1996, which substantially changed the treatment landscape, ushering in the highly active antiretroviral therapy (HAART) era. Approval came quickly, following the results of several large trials [22] and one relatively small but very important study, Merck 035.
Why are HIV benefits not available to all people?
Despite significant advancements in the industrialized world, in resource-limited settings the situation is still dramatic: optimal benefits are not accessible to all HIV -infected people because of the challenges to coverage and costs.
When did the UNAIDS drug access initiative start?
As a consequence, the UNAIDS Drug Access Initiative was launched in December 1997, and the first patients received drugs in Uganda and Cote d’Ivoire in early 1998.
Why is ART important for HIV?
ART is recommended for all individuals with HIV to reduce the morbidity and mortality associated with HIV infection (AI) and to prevent HIV transmission to sexual partners and infants (AI). ART should be initiated as soon as possible after HIV diagnosis (AII). When initiating ART, it is important to educate patients about the goals and benefits of ART and to identify and address barriers to care engagement and treatment adherence (AIII). Patients should also understand that currently available ART does not cure HIV. To improve and maintain immunologic function and maintain viral suppression, ART should be continued indefinitely without interruption. Initiating ART early is particularly important for patients with AIDS-defining conditions, those with acute or recent HIV infection, and individuals who are pregnant; delaying therapy in these subpopulations has been associated with high risks of morbidity, mortality, and HIV transmission.
How does ART reduce HIV?
The first well-established example of ART reducing the risk of HIV transmission is the use of ART during pregnancy to prevent perinatal transmission of HIV. Effective suppression of HIV replication is a key determinant in reducing the risk of perinatal transmission. In the setting of maternal viral load suppressed to <50 copies/mL near delivery, the use of combination ART during pregnancy has reduced the rate of perinatal HIV transmission from approximately 20% to 30% to 0.1% to 0.5%. 7,8 ART is thus recommended for all pregnant individuals with HIV, for both maternal health and for the prevention of HIV transmission to the newborn. In ART-naive pregnant individuals, ART should be initiated as soon as possible, with the goal of suppressing plasma viremia throughout pregnancy. All pregnant individuals should be tested for HIV upon confirmation of pregnancy, with testing repeated throughout pregnancy as needed for those at risk of HIV acquisition (see Maternal HIV Testing and Identification of Perinatal HIV Exposure in the Perinatal Guidelines ).
Why do people need rapid ART?
Since individuals may fail to engage in care between the initial HIV diagnosis (or first clinic visit) and the time ART is prescribed , some groups have proposed rapid ART initiation on the same day of HIV diagnosis as a strategy to increase ART uptake and engagement in care and to accelerate the time to ART-mediated viral suppression. Rapid ART initiation also has the potential to reduce the time during which people with newly diagnosed HIV can transmit HIV. The rapid ART initiation strategy is supported by randomized controlled trials that were performed in resource-limited settings outside of the United States 27-29 and observational trials in the United States that included both immediate initiation of ART (on the day of diagnosis) 30-32 and rapid ART initiation (within days or weeks of diagnosis). 32,33 The results from some of these studies are discussed below.
Why is it important to start ART early?
Initiating ART early is particularly important for patients with AIDS-defining conditions, those with acute or recent HIV infection, and individuals who are pregnant; delaying therapy in these subpopulations has been associated with high risks of morbidity, mortality, and HIV transmission.
How does viral suppression improve quality of life?
Durable viral suppression improves immune function and overall quality of life , lowers the risk of both AIDS-defining and non-AIDS–defining complications , and allows persons with HIV to live a lifespan approaching that of persons without HIV. 1.
What is ART therapy?

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.
When will the AIDS epidemic end in NYS?

What is the risk of ART?
The risk of IRIS increases when ART is begun at low CD4 cell counts (<100 cells/mm 3) or with the presence of specific opportunistic infections. Although the risk of IRIS is not a contraindication to initiating ART, clinicians and patients should be aware that the risk of developing IRIS is increased among individuals with lower CD4 counts. Patients at increased risk should be informed of the potential for a paradoxical clinical worsening after ART initiation.
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.
When is ART recommended in New York?

What is ART therapy?
Antiretroviral therapy (ART) is recommended for all people living with HIV, regardless of CD4 cell count, to consistently suppress viral load, maintain high CD4 cell counts, prevent AIDS, prolong survival, and reduce risk of transmitting HIV to others. 1, 2, 3 Research demonstrates that the success of ART, however, depends on the extent to which a patient takes his or her treatment according to the prescribed doses, dosing intervals, and other medication instructions. 4, 5 Several studies have shown that health care providers can positively impact medication-taking behaviors among HIV-infected patients by engaging in regular, ongoing discussions at every office visit that describe the benefits of ART adherence; track clinical measures that are influenced by adherence, such as a viral load; identify barriers to adherence; offer adherence support services; and provide information on other interventions that can improve adherence and reduce the risk of HIV transmission to others. 1, 2, 3, 4, 5, 6
How Can Holding Brief Conversations with Patients at Every Visit Help Improve ART Adherence?
Establishing ongoing brief conversations with patients in a supportive and nonjudgmental way encourages trust and facilitates opportunities to identify teachable moments in which HIV care providers can better help patients achieve sustained viral suppression. For example, HIV care providers can communicate the benefits of adherence by explaining that with ART medications, patients can now expect to live longer lives if they adhere to their ART regimen exactly as prescribed. Patients entering care should also understand the potential negative consequences of nonadherence such as increased mortality and morbidity, drug resistance, and risk of transmitting HIV to others. 3, 6
What Are Suggested Conversation Starters to Discuss Ongoing ART Adherence with Patients?
As recent research demonstrates, brief discussions about ART adherence at every follow-up visit can help improve patient success. 6 Following are a few questions probing ongoing adherence:
How to help HIV patients with nonadherence?
Ensure patients understand the treatment plan, including drug regimen, dosing schedule, and dietary restrictions. Prepare patients for situations or changes in routine that could trigger nonadherence or short-term interruption, such as side effects, substance use, or running out of HIV medicines. Remind patients to contact their HIV care provider or pharmacist immediately if they are experiencing side effects or need to refill medication prescriptions. Encourage patients to discuss their challenges with substance use and offer information or referrals for treatment options and support services.
How can HIV care providers communicate the benefits of adherence?
For example, HIV care providers can communicate the benefits of adherence by explaining that with ART medications, patients can now expect to live longer lives if they adhere to their ART regimen exactly as prescribed. Patients entering care should also understand the potential negative consequences of nonadherence such as increased mortality ...
Why is objectivity important in HIV care?
Objectivity and a nonjudgmental attitude are important. Health care providers can make it clear that even if they do not share patients’ views, they respect them. By understanding and respecting patients’ views, HIV care providers have the opportunity to improve the patient-health care provider relationship and make the patient more likely to be open and adherent.

What Is Antiretroviral Therapy?
Antiretroviral therapy (ART) involves using two or more antiretroviral drugs to suppress the virus to undetectable levels in the blood. This treatment can slow the progression of the disease to a point at which you can live a long, healthy life. 4
How It Works
Antiretroviral drugs do not kill HIV. Rather, they prevent the virus from making copies of itself by blocking stages in the virus's life cycle (also known as the replication cycle ). Antiretrovirals are so named because HIV is a type of virus known as a retrovirus. 4
Side Effects
While all drugs can cause side effects, current antiretrovirals tend to cause far fewer side effects than drugs of the past. Even so, side effects can occur and, in rare cases, be severe.
Tests
Once you have been diagnosed with HIV, your doctor will advise to you start treatment immediately to bring the virus under control. You will not only be counseled on how to take your drugs correctly (including dietary restrictions) but also advised on ways to maintain optimal adherence .
Other Treatments
There are no other medications other than antiretrovirals that can control HIV.
Talk to Your Doctor
The choice of ART relies heavily on the results of a genetic resistance test that helps determine which antiretrovirals work best based on your virus's genetic profile. But it is not the sole factor involved in the selection of ART. 17
Summary
Antiretroviral therapy is used to control HIV. It relies on drugs that inhibit points of the viral replication cycle so the virus cannot make copies of itself and infect immune system cells. Antiretroviral drugs are usually given daily in the form of a pill, which may contain a combination of drugs. These medications may have side effects.
