What is antiretroviral therapy How does it work?

Antiretroviral drugs HIV is treated with antiretroviral medicines, which work by stopping the virus replicating in the body. This allows the immune system to repair itself and prevent further damage. A combination of HIV drugs is used because HIV can quickly adapt and become resistant.

How effective is HAART?

HAART reduces mortality among adults infected with HIV. A randomized trial among HIV-infected adults with CD4 cell counts of < 200 cells/mm3 found a 57% lower mortality associated with HAART, compared with a regimen including 2 nucleoside analogues [1].

When do you start HAART therapy?

Accordingly, current guidelines suggest deferring therapy until later in the course of infection—that is, until the CD4+ lymphocyte count decreases to <350 cells/µL [13] or <200 cells/µL [14]. However, the optimal stage of HIV infection at which to begin therapy has not been defined.

How do antiretroviral drugs work answers?

They work by blocking cell receptors, called CCR5 and CXCR4, respectively, and prevent HIV from attaching to the host cell, interrupting the HIV life cycle in its earliest stages. gp120 inhibitors, such as DS003, bind to the gp120 proteins HIV needs to attach to healthy cells.

What is the window period for HIV testing?

The time between potential HIV exposure and an accurate test result is referred to as the window period. Improvements in testing technology continue to reduce the detection window period, and, therefore, the time to diagnosis and treatment of early HIV infection.

What are the different types of HIV tests?

How many copies of HIV are there in a milliliter of blood?

During periods of active viral replication, a single milliliter of blood may contain more than 1 million copies of the virus.

What is PEP in HIV?

Post-Exposure Prophylaxis (PEP) For individuals who need to prevent HIV after a single high-risk event of potential HIV exposure such as unprotected sex, needle-sharing injection drug use or sexual assault, there is another option called post-exposure prophylaxis (PEP).

What is the final stage of HIV?

HIV is a fatal infection whose final terminal stage is referred to as Acquired Immunodeficiency Syndrome (AIDS). Individuals, countries and cultures, particularly in central and southern Africa, have suffered tremendously due to the devastation that accompanies HIV, rightly referred to as the “Scourge of Our Time.” 1,2 In the past few years, new treatments have been developed which have extended by decades the lifespan of those infected, effectively shifting HIV from an acute terminal illness to a chronic debilitating condition requiring a different perspective on care and monitoring. As healthcare professionals, it is imperative that we keep current on new information regarding HIV as it is continuously being discovered. Information concerning the spread (i.e., modes of transmission), treatment and care of the HIV infected individual, as well as those individuals who progress into the final stage of AIDS is crucial as we strive to help those infected live healthier more satisfying lives.

How is HIV transmitted?

Both types of HIV have AIDS as their end stage and both are transmitted through blood, sexual contact and body fluids. Current tests are available to detect both HIV-1 and HIV-2. Be alert, as HIV changes and mutates readily, a single infected individual may have several different strains of HIV inside their body.

Can HIV reproduce?

Like other viruses, HIV can neither reproduce nor grow independently. HIV requires a living host, in this case, a human, in order to make copies of itself, a process known as replication, which, in the end, destroys the host cells commandeered to be production factories. For most viruses, human bodies respond by quickly destroying the invader by means of the human immune system. Unfortunately, it is the immune system itself that the HIV infection desires to invade and replicate in, leading to a progression where the very source of protection against viruses becomes a cellular killing ground destroying the body’s defenses and giving birth to masses of new viral particles.

What are the symptoms of HIV?

A rash, fatigue and sore throat are often present, as well as less common symptoms such as headache, diarrhea, stomach ache, or ulcerations of the eso phagus. Around 70% of those with acute HIV infection develop noticeable symptoms during the acute stage of infection.
