Which are the current HIV/AIDS Treatments?

Human Immunodeficiency Virus (HIV) affects the immune system by destroying CD4 cells, a type of white blood cell that can fight infections. Losing these cells makes it difficult to fight infections and some HIV-related cancers. Without any HIV treatments, virus can gradually destroy the immune system by evolving into AIDS, the acquired immunodeficiency syndrome, the last stage of HIV infection. Not everyone with HIV develops AIDS.

HIV (AIDS) Treatment types

To date, there are no treatments to combat HIV, although antiretroviral treatments (ART) can in some way control the virus; this means that HIV positive people can live long and healthy lives. Research is now geared towards two possible cures. Functional cure aims to reduce HIV to permanently undetectable and harmless levels, but some residual viruses may remain; someone thinks that antiretroviral treatment is effectively a functional cure, but most consider it as something that suppresses the virus without the need for ongoing antiretroviral treatment. Other types of research aim to seek a Sterilizing cure, capable of completely eradicating the virus from the body, but this is a complex and risky way. There is only one known person who’s been cured in this way: Timothy Brown, also known as the ‘Berlin Patient‘. There are encouraging tests on HIV vaccines, but they are only partial protections: researchers and scientists do believe that we can find a cure for HIV, a virus of which we know a lot today. In 2007-08, Brown was treated with chemotherapy and a bone marrow transplant (for the treatment of leukemia), coming from a subject naturally resistant to HIV. Subsequently, without scientists understanding the reason, Brown recovered from HIV. Unfortunately, however, bone marrow transplants can be dangerous, so they are not a practical solution to treat yourself from HIV.

What are the medical HIV/AIDS treatments?

There are different medical treatments for HIV/AIDS, depending on the behavior they adopt towards the virus. A first type is represented by medicines that block or change the enzymes that HIV needs to make copies of itself, thereby reducing the amount of HIV in the body. They are: Nucleoside reverse transcriptase inhibitors (NRTIs), able to block the reverse transcriptase enzyme; the Non-nucleoside reverse transcriptase inhibitors (NNRTIs) which bind to and later change the reverse transcriptase enzyme; Integrase inhibitors that block the integrase enzyme; Protease inhibitors (PIs) which block the protease enzyme. A second group of HIV/AIDS treatments is represented by those medicines that can interfere with the ability of the virus to infect the cells of the immune system CD4: the Fusion inhibitors block HIV from entering the cells; CCR5 antagonists and post-attachment inhibitors block different molecules on the CD4 cells. In some other cases, people prefer to use more than one medicine, like Pharmacokinetic enhancers, that  boost the effectiveness of certain HIV/AIDS medicines, slowing the breakdown of the other medicine, or Multidrug combinations, including a mix of two or more different HIV/AIDS medicines.

What to do in case of HIV/AIDS?

Once the virus has been diagnosed, it is essential to start taking HIV / AIDS medications as soon as possible, particularly in cases of: pregnancy; have ascertained that you have contracted AIDS; in case of some HIV-related diseases and infections; have an early HIV infection (the first 6 months after HIV infection). Taking medicines every single day is crucial; forgetting the daily doses recommended by your doctor or following a regular schedule could cause the HIV virus to become resistant to medicines.
