Treatment failure can also occur in people who are fully compliant, usually many years after treatment. This is especially true for those who take some older antiretroviral medications, some of which last (and last longer) than others. However, if treatment failure occurs within a relatively short period of time, adherence is almost always poor.
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 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.
How long does it take to cure HIV?
1 HIV medicine is called antiretroviral therapy (ART). 2 There is no effective cure for HIV. But with proper medical care, you can control HIV. 3 Most people can get the virus under control within six months. 4 Taking HIV medicine does not prevent transmission of other sexually transmitted diseases.
What is the treatment for HIV?
HIV treatment involves taking medicines that slow the progression of the virus in your body. HIV is a type of virus called a retrovirus, and the combination of drugs used to treat it is called antiretroviral therapy (ART). ART is recommended for all people living with HIV, regardless of how long they’ve had the virus or how healthy they are.
Can HIV Meds Fail?
Current treatments available for the human immunodeficiency virus (HIV) are very effective, allowing people with the virus to live long and relatively healthy lives. However, sometimes your specific treatment can start to fail, which can raise your viral load and trigger symptoms.
What happens if the antiretroviral drugs are unsuccessful?
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.
How common is HIV drug resistance?
The prevalence of transmitted drug resistance is estimated to be between 12% and 24% among people living with HIV in the U.S. Pretreatment HIV drug resistance can occur before treatment is even started. This may occur if a person is exposed to HIV medications when they become infected with HIV.
How long HIV patient can survive with treatment?
For people who had a CD4 count between 200 and 350 and an undetectable viral load one year after starting treatment, life expectancy was similar to that of people in the general population. Among men, a 35 year old and a 50 year old could expect to live to 78 and 81 years respectively.
Why does treatment failure occur?

What does it mean when your HIV is suppressed?
Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood. HIV medicine can make the viral load so low that a test can’t detect it (called an undetectable viral load ). If your viral load goes down after starting HIV treatment, that means treatment is working.
What is the amount of HIV in the blood called?
The amount of HIV in the blood is called viral load . Taking your HIV medicine as prescribed will help keep your viral load low and your CD4 cell count high.

What is drug resistance in HIV?
What Is HIV Drug Resistance? Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself. Variations of HIV that develop while a person is taking ART can lead to drug-resistant strains of HIV.
How soon can you start ART for HIV?
Treatment guidelines from the U.S. Department of Health and Human Services recommend that a person living with HIV begin ART as soon as possible after diagnosis. Starting ART slows the progression of HIV and can keep you healthy for many years.
Is HIV treatment a prevention?
There is also a major prevention benefit. People living with HIV who take HIV medication daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners. This is called treatment as prevention.
Can HIV be drug resistant?
A person can initially be infected with drug-resistant HIV or develop drug-resistant HIV after starting HIV medicines. Drug-resistant HIV also can spread from person to person. Drug-resistance testing identifies which, if any, HIV medicines won’t be effective against your specific strain of HIV.
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.
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 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.
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 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.
What is the cure for HIV?
There are two different visions of a potential HIV cure: treatment-free remission and viral eradication. Treatment-free remission means the virus is controlled without the need for ART drugs, which a person has to take every day for life. Millions of people who have HIV can’t afford ART, so other treatments are needed.
What drugs can kill HIV?
Other types of drugs that may be able to seek out and kill HIV include histone deacetylase (HDAC) inhibitors, protein kinase activators, latency securing agents, and immunotoxins. These drugs may be used in combination.
What would be the first part of HIV?
The first part would involve drugs that make the cells in the HIV reservoir multiply and express proteins that are a like a signal to your immune system. The second part would include drugs that detect those protein signals, then seek out and kill the virus.
Can HIV be treated with ART?
Millions of people who have HIV can’t afford ART, so other treatments are needed. This idea of an HIV cure is also called a functional cure. Treatment-free remission means that you’d: Live a healthy life that’s of normal length. Not have to take ART or any other HIV-related drugs to keep the virus under control.
Can HIV be wiped out?
They don’t prevent infection, but stimulate your own immune system to fight it. Viral eradication is another way of looking at a potential cure. It’s also known as a sterilizing cure. Scientists believe it would take a two-part treatment to wipe out HIV in a person’s body.
Can you get HIV if you stop taking ART?
They’re at almost no risk of passing the virus to others. But if you have HIV and take ART drugs, the virus still lives inside a group of cells called the HIV reservoir. If you stop taking ART, the virus in the reservoir can spike again. Right now, there’s still no complete cure for HIV infection.
How to remember if you took HIV medication?
