how was the medical treatment for hiv discovered

In 1996, in Vancouver, researchers at the 11th International Conference on AIDS introduced the concept of highly active antiretroviral therapy (HAART). This regimen requires people with HIV to take a combination of at least three medications daily. HAART, which is commonly known as antiretroviral therapy, became the new treatment standard in 1997.

How did HIV become treatable?

This was a life-changing breakthrough. A patient with HIV can develop AIDS when their immune system is badly damaged, and their body isn't able to fight infections. Since these new medicines could suppress the virus and prevent immune system damage, they prevented AIDS from developing.

Who discovered AZT?

Jerome Horwitz invented the drug AZT. It was approved in 1987, the first drug that significantly helped decrease the devastating death toll of AIDS.

How does HIV become resistant to drugs?

Such resistance generally occurs when a random mutation during the replication of HIV causes a small genetic change in the virus's RNA, in the process making it less vulnerable to the effects of antiviral drugs. Drug resistance can seriously complicate treatment by rendering drugs less effective or even completely ineffective. Further, once an organism has developed resistance to one drug, it can also become resistant to other drugs in the same class (cross-resistance) or to a number of different drugs (multidrug resistance).

What is the new class of anti-HIV drugs?

After 1991, several other nucleoside analogs were added to the anti-HIV arsenal, as were a new class of anti-HIV drugs called the non-nucleoside analog reverse transcriptase inhibitors which work in similar ways to the nucleoside analogs but which are more quickly activated once inside the bloodstream.

What is the class of antiviral drugs that prevents HIV infection?

Next to be developed were the class of antiviral drugs known as protease inhibitors, which were distinctly different from the reverse transcriptase inhibitors in that they do not seek to prevent infection of a host cell, but rather to prevent an already infected cell from producing more copies of HIV.

Why is combination therapy important?

By using more than one drug at a time, combination therapy is able to "pin down" HIV from more than one angle, so that even if one drug fails, another can continue to suppress viral replication.

How do retroviruses work?

Whereas most viruses retain their genetic information on strands of DNA, retroviruses like HIV employ simpler RNA. The virus's outer coat consists of particular glycoproteins, which can form biochemical bonds with particular proteins (such as CD4) that are found on the surface of some cells, notably those in the immune system. Once bonding occurs, the HIV life cycle requires the insertion of its own genetic material into the host cell and ultimately the use of three important viral enzymes. The first, reverse transcriptase, converts RNA into DNA (a process called "reverse transcription"). The second, integrase, integrates the viral DNA into the human cell's DNA. The third, protease, later cleaves off new copies of the viral proteins, allowing new virus particles to be assembled and enabling these new viruses to leave the cell. These three enzymes are essential to the process of viral replication, and most advances in HIV treatment have come from inhibiting the activity of these enzymes.

When was ZDV approved?

From Monotherapy to Combination Therapy. In 1986 the U.S. Food and Drug Administration (FDA) approved the first antiviral drug zidovudine (ZDV; AZT) for use in preventing HIV replication by inhibiting the activity of the reverse transcriptase enzyme.

In the lead up to the discovery of HIV, immune system deficiency disorders were increasingly being detected within America. The causes of this increase were initially unknown. This led to a number of proposals concerning the possible origins of these disorders. Theories varied from ideas relating to immune system overload to the use of 'poppers' within the gay community as the cause of this disease.

Where did HIV come from?

HIV is thought to have developed from Simian Immunodeficiency Virus (SIV), first transmitted to humans who consumed and butchered primates for bushmeat in the African country of Cameroon. The virus is thought to have began spreading amongst the local populations and adapting to the human body. As the virus adapted, it's virility amongst humans increased causing greater rates of infection during the 1950's. After this the rise of worldwide travel ensured its development into a global pandemic.

How did HIV become a global disease?

Due to the similarity of symptoms from HIV infection with other illnesses, along with its long incubation period, HIV was able to silently spread around the globe. The lack of severe symptoms following infection meant that the virus went undetected and did not trigger the normal World Health Organisation (WHO) safety procedures used to isolate new diseases and prevent them from spreading.

When was the first case of HIV?

How did HIV and AIDS change?

The early months and years of HIV and AIDS research were marked by rapid change. Scientists not only grappled with a new killer illness that was poorly understood, but the virus itself exhibited new characteristics almost as fast as researchers could identify them. Hemophiliacs, who routinely receive blood transfusions, were also identified as an at-risk patient group. An AIDS outbreak in Haiti further added to the confusion. New cases of heterosexual transmission reinforced early theories that HIV was purely sexually transmitted; however, this theory had to be discarded as mother-child in utero transmission was documented.

Who proposed that the epidemic of HIV most likely reflects changes in population structure and behaviour in Africa during the 20th century?

Beatrice Hahn , Paul M. Sharp , and their colleagues proposed that " [the epidemic emergence of HIV] most likely reflects changes in population structure and behaviour in Africa during the 20th century and perhaps medical interventions that provided the opportunity for rapid human-to-human spread of the virus".

Why did HIV emerge?

In several articles published since 2001, Preston Marx, Philip Alcabes, and Ernest Drucker proposed that HIV emerged because of rapid serial human-to-human transmission of SIV (after a bushmeat hunter or handler became SIV-infected) through unsafe or unsterile injections.

How is SIV transmitted?

According to the natural transfer theory (also called "hunter theory" or "bushmeat theory"), in the "simplest and most plausible explanation for the cross-species transmission" of SIV or HIV (post mutation), the virus was transmitted from an ape or monkey to a human when a hunter or bushmeat vendor/handler was bitten or cut while hunting or butchering the animal. The resulting exposure to blood or other bodily fluids of the animal can result in SIV infection. Prior to WWII, some Sub-Saharan Africans were forced out of the rural areas because of the European demand for resources. Since rural Africans were not keen to pursue agricultural practices in the jungle, they turned to non-domesticated animals as their primary source of meat. This over-exposure to bushmeat and malpractice of butchery increased blood-to-blood contact, which then increased the probability of transmission. A recent serological survey showed that human infections by SIV are not rare in Central Africa: the percentage of people showing seroreactivity to antigens —evidence of current or past SIV infection—was 2.3% among the general population of Cameroon, 7.8% in villages where bushmeat is hunted or used, and 17.1% in the most exposed people of these villages. How the SIV virus would have transformed into HIV after infection of the hunter or bushmeat handler from the ape/monkey is still a matter of debate, although natural selection would favour any viruses capable of adjusting so that they could infect and reproduce in the T cells of a human host.

What is SIV related to?

An SIV strain, closely related to HIV, was interspersed within a certain clade of primates. This suggests that the zoonotic transmission of the virus may have happened in this area. Continual emigration between countries escalated the transmission of the virus.

How many groups of HIV-2 have been found?

There are six additional known HIV-2 groups, each having been found in just one person. They all seem to derive from independent transmissions from sooty mangabeys to humans. Groups C and D have been found in two people from Liberia, groups E and F have been discovered in two people from Sierra Leone, and groups G and H have been detected in two people from the Ivory Coast. These HIV-2 strains are probably dead-end infections, and each of them is most closely related to SIVsmm strains from sooty mangabeys living in the same country where the human infection was found.
