What is HIV treatment failure and how does it affect you?
HIV treatment failure occurs when your antiretroviral drugs are no longer able to suppress the virus or prevent the deterioration of your immune system, leaving you vulnerable to opportunistic infections . Treatment failure can be classified as being either virologic (pertaining to the virus), immunologic (pertaining to the immune system), or both.
How many people with HIV are still waiting for treatment?
HIV Treatment Access —As of the end of 2019, 25.4 million people with HIV (67%) were accessing antiretroviral therapy (ART) globally. That means 12.6 million people are still waiting.
How is treatment failure managed in children with HIV?
Children who require evaluation and management of treatment failure should be managed by or in collaboration with a pediatric HIV specialist (AI*). Treatment failure can be categorized as virologic failure, immunologic failure, clinical failure, or some combination of the three.
What percentage of new HIV cases are from injectable drugs?
That percentage is has remained stable from 2010 to 2017. Another group who continues to be impacted by HIV and AIDS are people who inject drugs. They make up 7% of new diagnoses. We know that starting treatment as soon as possible after diagnosis is key to suppressing the virus, slowing HIV progression, and staying healthy for a long time.
How often does HIV treatment fail?
The rate of viral failure was 8.9 per 100 patient-years in those with low-level viremia versus 3.3 per 100 patient-years in those without low-level viremia.
Is there any successful treatment for HIV?
While there's no cure for HIV, there are very effective treatments that enable most people with the virus to live a long and healthy life.
What is treatment failure in HIV?
Treatment failure is defined as repeated HIV RNA values above the lower limit of detection of a sensitive assay (usually 50 copies per mL). This is based on evidence that the maximum clinical benefit of antiretroviral therapy is derived by keeping the viral load as low as possible.
Is HIV treatment lifelong?
HIV medicines also reduce the risk of HIV transmission. Because HIV requires lifelong treatment, it is important for people with HIV to regularly visit their health care provider. Ongoing medical care includes monitoring to make sure a person's HIV treatment regimen is keeping the virus under control.
Can I become detectable again?
People also become detectable when they stop taking their HIV medications or take them only partially. It may take between a week to several weeks after stopping HIV treatment for HIV to become detectable again, but people will see the levels of virus in their body go up to detectable levels.
What are treatment failures?
Treatment failure is defined as persistent symptoms or signs or a sustained four-fold increase or failure to achieve a four-fold decrease in those with high-titer initial results (equivalent to a two-dilution change) in nontreponemal test titer.
What is the incidence of HIV?
HIV incidence refers to the estimated number of new HIV infections during specified period of time (such as a year), which is different from the number of people diagnosed with HIV during a given year.
What is the highest rate of HIV in 2019?
In 2019, the highest rate was for Blacks/African American persons (42.1), followed by Hispanic/Latino persons (21.7) and persons of multiple races (18.4). By sex at birth, the annual number of new HIV infections in 2019, as compared to 2015, decreased among males, but remained stable among females.
How many people have HIV in 2019?
According to another CDC report, of the estimated 1.2 million people with HIV (diagnosed and undiagnosed) in 2019, about 65.9% received some HIV care, 50.1% were retained in care, and 56.8% were virally suppressed or undetectable.
What age group is the highest in HIV?
By age group, in 2019, the number of new HIV diagnoses was highest among people aged 25 to 29.
How long can you live with HIV?
(Some people can live with HIV for years before they are diagnosed; others are diagnosed soon after acquiring HIV.)
What is the HIV plan?
The HIV Plan is a roadmap for ending the HIV epidemic in the United States by 2030. The HIV Plan is the nation’s third consecutive five-year national HIV strategy and covers 2021-2025, with a 10-year goal of reducing new HIV infections by 90% by 2030.
What is treatment failure?
Immunologic failure refers to a suboptimal immunologic response to therapy or an immunologic decline while on therapy, but no standardized definition exists.
How many ARV agents should be used in a patient's regimen?
After deciding that a change in therapy is necessary, a clinician should attempt to identify at least two, but preferably three, fully active ARV agents from at least two different drug classes to use in a patient’s new regimen. The clinician should consider all of the patient’s past and recent drug-resistance test results, the patient’s prior exposure to ARV drugs, whether the patient is likely to adhere to the regimen, and whether the patient finds a particular regimen acceptable. 34–38 This process often requires using agents from one or more drug classes that are new to the patient. However, clinicians should be aware that drug-resistance mutations can confer cross-resistance within a drug class, so a drug that is new to the patient may still have diminished antiviral potency. Substituting or adding a single drug to a failing regimen is not recommended, because this is unlikely to lead to durable virologic suppression and will likely result in additional drug resistance.
What is the main barrier to sustained virologic suppression in adults and children?
Although many factors can contribute to virologic failure, the main barrier to sustained virologic suppression in adults and children is incomplete adherence to medication regimens, with subsequent emergence of viral mutations that confer partial or complete resistance to one or more components of the ARV regimen.
What is virologic failure?
Virologic failure refers to either an incomplete initial response to therapy or a viral rebound after virologic suppression is achieved. Virologic suppression is defined as having a plasma viral load below the lower level of detection, as measured by highly sensitive assays with lower limits of quantitation of 20 copies/mL to 75 copies/mL. Virologic failure is defined as repeated instances of a plasma viral load ≥200 copies/mL after 6 months of therapy. Laboratory results must be confirmed with repeat testing before a final assessment of virologic failure is made.
What is the goal of virologic suppression?
When complete virologic suppression cannot be achieved, the goals of therapy are to preserve or restore immunologic function (as measured by CD4 T lymphocyte values), prevent clinical disease progression, and prevent the development of additional drug resistance that could further limit future ARV drug options (AII).
Why is it impossible to provide an effective and sustainable therapeutic regimen?
It may be impossible to provide an effective and sustainable therapeutic regimen, because no combination of currently available agents is active against extensively drug-resistant virus in a patient, or because a patient is unable to adhere to or tolerate ART.
Who should be consulted when determining which new regimen will have the best chance of achieving complete virologic suppression
A pediatric HIV specialist should be consulted when determining which new regimen will have the best chance of achieving complete virologic suppression in children who have already experienced treatment failure.

What is the continuum of HIV treatment?
HIV Care Continuum —The term HIV care continuum refers to the sequence of steps a person with HIV takes from diagnosis through receiving treatment until his or her viral load is suppressed to undetectable levels. Each step in the continuum is marked by an assessment of the number of people who have reached that stage.
What is the continuum of care for HIV?
HIV Care Continuum —The term HIV care continuum refers to the sequence of steps a person with HIV takes from diagnosis through receiving treatment until his or her viral load is suppressed to undetectable levels. Each step in the continuum is marked by an assessment of the number of people who have reached that stage. The stages are: being diagnosed with HIV; being linked to medical care; starting ART; adhering to the treatment regimen; and, finally, having HIV suppressed to undetectable levels in the blood. UNAIDS’s 90-90-90 goals set as targets that by 2020, 90% of all people with HIV will know their HIV status, 90% of all people who know their status will be on ART, and 90% of all people receiving ART will have viral suppression. Tracking progress toward those goals, UNAIDS reports that in 2020, of all people with HIV worldwide: 1 84% knew their HIV status 2 73% were accessing ART 3 66% were virally suppressed

The Numbers
The most current numbers from 2018 show about 1.2 million people in the U.S. were living with HIV.
The Undiagnosed
You can have HIV for some time and not know it. Of the 1.2 million people in the U.S. thought to be living with HIV, it’s estimated that about 1 in 7 don’t know they have it. That means they aren’t getting treatment and they can unknowingly pass the virus to someone else. Those most likely to be unaware of having an HIV infection are young people.
New HIV infections
"HIV incidence" is an estimated number of people newly infected with HIV during a year. It’s an educated guess. It’s not the same as the number of people who are diagnosed with HIV.
HIV Impact
About 37,800 people were diagnosed with HIV in 2018. New diagnoses in the U.S. went down 11% from 2010 to 2017 in teens and adults. But HIV continues to have the greatest impact on gay and bisexual men, and racial and ethnic minorities:
How many people died from AIDS in 2017?
Following the epidemic of HIV/AIDS, the global expansion of the combination antiretroviral treatment (ART) has been the primary contributor to the 51% decline AIDS-related deaths, from a peak of 1.9 million (1.4–2.7 million) in 2004 to 0.94 million (0.67–1.3 million) in 2017.
How does antiretroviral treatment affect HIV?
However, treatment options can be impaired by the development of antiretroviral treatment failure. Regular monitoring of the Human Immunodeficiency Virus treatment outcome via viral load tests is the key approach. There is a scarcity of information about HIV treatment failure and risk factors in the study area. Therefore, the study was aimed to assess antiretroviral treatment failure and associated factors among patients on first-line antiretroviral treatment at Tefera Hailu Memorial Hospital, Sekota, northeast Ethiopia.
What are the predictor variables of ART failure?
The rate of ART failure was considerably high. Poor adherence, low CD4 + count, prolonged ART, and drug interruption were found to be the most predictor variables for virological and immunological failures. The discrimination power of the immunological parameter was low in comparison to virological measurements as standard methods. Therefore, the study highlighted the need for more attention and efforts to curb associated factors and maximize virological tests for monitoring treatment failures.
Does immunology have a lower accuracy?
But immunologic parameter s have a lower accuracy of identifying virologic failures, leading to premature changes or continuous uses of failed regimens. This leads to more complex HIV drug failures, and the health impact increases morbidity and mortality rates in settings where virologic tests are not available.
What is the normal blood count for HIV?
The immune status of people with HIV is measured by a blood test called the CD4 count. "Normal" values are typically defined as being 500 cells/mL or above, while those below 200 are classified as AIDS . In the past, the CD4 count (and other values such as the CD4/CD8 ratio) factored greatly into how HIV was treated.
What are the problems with HIV?
Poor drug absorption, which can happen to people with chronic HIV-associated diarrhea or other malabsorption issues. Not following food requirements, which can also affect drug absorption and metabolism. Cost and affordability, including the lack of adequate health insurance.
What happens when antiretroviral drugs fail?
HIV treatment failure occurs when your antiretroviral drugs are no longer able to suppress the virus or prevent the deterioration of your immune system, leaving you vulnerable to opportunistic infections . Katarzyna Bialasiewic / Getty Images.
How many antiretroviral drugs are there?
Generally speaking, the doctor will consider drugs from a class that you have not yet been exposed to. There are currently 26 individual antiretroviral drugs and 22 fixed-dose combination drugs comprised of two or more antiretrovirals approved by the Food and Drug Administration. 6.
How many T cells can you get from low pretreatment CD4?
3 Similarly, those with mild to moderate immune suppression will sometimes see an improvement of several hundred T-cells, while others will see their numbers shoot well above 1,000 or 1,500.
What happens if you have virologic failure?
Changing Therapy. If virologic failure is declared, your doctor will order one or more tests to evaluate your "viral pool.". When you have HIV, you do not have just one virus but rather a multitude of variants, some of which are drug-resistant.
How many copies of a viral load can be detected?
When antiretroviral therapy is working, the viral load should be fully undetectable, meaning that it is below the level of detection (under 20 to 75 copies/mL, depending on the test). 1 If failure is allowed to continue, the viral load will continue to rise, in some cases into the millions.
