Immune system therapies are essentially treatments that help the body by modifying components of the immune system to be more effective. part from drugs designed to attack HIV directly, a number of immune therapies are also being ivestigated for use by people with HIV for the purpose of boosting immunity and to try to correct theabnormalities seen in HIV infection.

How HIV medications are combined and the order in which they are given are important factors to consider when designing treatment strategies for patients new to antiretroviral therapy, says a new study funded by the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health. When HIV-infected individuals begin treatment with a combination of the drugs zidovudine, better known as AZT, lamivudine and efavirenz, the drugs retain their effectiveness for a longer period of time than when individuals begin treatment with one of several other three-drug regimens. HAART (Highly Active Antiretroviral Therapy) utilizes multiple combinations of HIV drugs to stop the virus from progressing. The purpose of HAARt is combined various HIV medications to supress HIV in a multitude of ways. Two key classes include those that prevent the virus from copying itself, called reverse transcriptase (RT) inhibitors, and those that prevent the virus from becoming infectious, called protease inhibitors. RT inhibitors can be further broken down into nucleoside RT inhibitors, which halt HIV replication by making faulty DNA building blocks, and non-nucleoside inhibitors, which bind to the enzyme reverse transcriptase to prevent the virus from copying itself. HIV drug combinations can lose effectiveness over time and doctors must then adjust treatment. Combination HIV AIDS regimens are our currently most effective method in the fight against HIV/AIDS. Using this regimens we have been able to prolong lives, improve quality of life and even slow the transmission of HIV/AIDS.
