When was AIDS discovered?
Patients with the mysterious immune disorder now known as AIDS had been arriving at the NIH Clinical Center since 1981. When the human immunodeficiency virus (HIV) was identified by Luc Montagnier, M.D., at the Pasteur Institute in Paris, and then shown by NCI’s Robert Gallo, M.D., in 1984 to be the cause of AIDS, NCI scientists were poised to rapidly act on the discoveries.
What is the first drug to be tested for HIV?
They developed an assay to test the utility of drugs against HIV and gathered a number of promising compounds to test. Azidothymidine (AZT), a compound first synthesized by Jerome Horowitz, Ph.D., in 1964 as an anti-cancer drug, was among the drugs initially tested. In a preliminary clinical trial done largely in the NIH Clinical Center, NCI scientists showed that AZT could improve the immune function of AIDS patients. In a randomized trial, it was subsequently shown to improve survival of AIDS patients. In 1987, it became the first drug approved by the U.S. FDA for treatment of the disease. AZT was subsequently shown to markedly reduce the perinatal transmission of HIV.
How has HAART helped with AIDS?
HAART has dramatically reduced AIDS mortality and transmission of the virus in many parts of the world where there has been ready access to the medication. It has also markedly reduced the development of the many AIDS-related cancers that are associated with immunodeficiency. CCR scientists have continued to study the virus, including malignancies such as Kaposi sarcoma that are related to and influenced by HIV infection, and patients living with HIV today have even more treatment options.
What enzymes were used to map out the structure of HIV?
NCI scientists helped map out the structure of another essential viral enzyme, the HIV protease, to guide the design of a new class of HIV drugs. When combined with reverse transcriptase inhibitors, protease inhibitors, developed in the mid-1990s, dramatically suppressed replication of the virus, often reducing it to undetectable levels.

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.
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).
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?

Why is the death rate of AIDS declining?
This decline in AIDS deaths has been attributed to a variety of causes, including improved treatment of and prophylaxis against opportunistic infections as well as a long-projected epidemiological drop-off as the huge first wave of people infected with HIV in the 1970s or early 1980s died in the early to mid-1990s. However, the introduction of combination therapies has also played a crucial role in this decline. Indeed, combination therapies have brought numerous individuals back from the proverbial "brink of death," restoring many thousands to a semblance of their earlier health and sharply reducing incidence of new HIV-related opportunistic infections and cancers. It appears this trend of declining deaths will continue, though because the advances in treatment have been only available for a relatively short time, no one can say for certain what the long term effects of these treatments will be. Long term use of antivirals may provide a window of opportunity for immune-boosting therapies and perhaps even restoration to normal immunological functioning. On the other hand, continued use of these powerful, toxic medications presents complicating factors of its own -- notably damage to vital organs such as the liver, kidneys and heart.
When did monotherapy start?
Despite this proliferation of drug options, the standard antiviral therapy for HIV-infected individuals between 1986 and 1995 for the most part remained "monotherapy" or treatment with a single drug. Such drugs appeared to be partly efficacious, although there was a great variation in effectiveness among individuals.

What caused the pneumocystis epidemic?
The epidemics spread likely due to infected glass syringes and needles. Malnutrition was not considered a cause, especially because the epidemics were at their height in the 1950s. At that time war torn Europe had already recovered from devastation. Researchers state that the most likely cause was a retrovirus closely related to HIV (or a mild version of HIV) brought to Europe and originating from Cameroon, a former German colony. The epidemic started in the Free City of Danzig in 1939 and then spread to nearby countries in the 1940s and 1950s, like Switzerland and The Netherlands.

When did the AIDS epidemic start?
In late 1983 , the global presence of the mysterious virus motivated European authorities and the WHO to classify the growing number of diagnoses as an epidemic. In addition to the outbreak in the U.S., patients with similar symptoms were documented in 15 European countries, 7 Latin American countries, Canada, Zaire, Haiti, Australia and Japan. Of particular concern was an outbreak in central Africa among heterosexual patients. In the U.S., the mortality rate approached 100%. The first annual International AIDS meetings were held in 1985.
What was the name of the drug that was approved by the FDA in record time?
Other drugs went into trial, with mixed success. A drug known as ACTG 076 showed particular promise in mother-to-infant transmissions, and a drug called Saquinavir was approved by the FDA in record time.
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.
How many people have HIV?
When HIV first began infecting humans in the 1970s, scientists were unaware of its existence. Now, more than 35 million people across the globe live with HIV/AIDS.

The U.S. Agency for International Development (USAID) estimated that by 2010, 40 million children in developing African nations would have lost one or both parents to AIDS. Image via Avert.org. Insufficient responses to early outbreaks of HIV/AIDS in African countries caused infection rates to skyrocket in the 1990s.
The first cases of AIDS
The New York Times was the first newspaper to report a new syndrome, seen in the homosexual communities of San Francisco and New York, on 3rd July 1981. Previously healthy men, some only in their 20s were suffering from rare diseases usually only seen in the elderly, such as the rare cancer: Kaposi’s sarcoma.
The identification of a virus
In January 1984 research was published which linked a number of cases of AIDS, and suggested that the disease was sexually transmitted.
The search for a treament
Once it was known that AIDS was caused by a human retrovirus, the search for drug-treatments began. The viral enzyme reverse transcriptase, is used by retroviruses use to construct DNA from their viral RNA once they have infected a cell. Humans and other mammals do not make this enzyme, making it an obvious drug target.
When did NRTI drugs get FDA approval?
In the early 1990s, additional NRTI drugs gained FDA approval. The development of AZT and other NRTIs showed that treating HIV was possible, and these drugs paved the way for discovery and development of new generations of antiretroviral drugs.
How long does a person live with HIV?
In the 1980s, the average life expectancy following an AIDS diagnosis was approximately one year. Today, with combination antiretroviral drug treatments started early in the course of HIV infection, people living with HIV can expect a near-normal lifespan. Watch NIAID Director Anthony S. Fauci, M.D., reflect on advances in HIV treatment.
What did AZT do?
In the laboratory, AZT suppressed HIV replication without damaging normal cells, and the British pharmaceutical company Burroughs Wellcome funded a clinical trial to evaluate the drug in people with AIDS. Used alone, AZT decreased deaths and opportunistic infections, albeit with serious adverse effects. In March 1987, AZT became the first drug ...
What is the role of identifying new drug targets?
Identification of novel drug targets has played a key role in discovery and development of new antiretroviral drug classes. For example, since the 1980s, scientists have known that a molecule called CD4 is the primary receptor for HIV on immune cells. In the mid-1990s, NIAID scientists reported the discovery of a co-receptor called CXCR4, which is required for entry of certain HIV strains into immune cells. This discovery inspired researchers to look for other co-receptors. A number of research groups, including NIAID scientists, determined that a different receptor called CCR5 is actually the primary co-receptor used by HIV to infect immune cells. This work laid the foundation for the development of the CCR5-blocking drug maraviroc, which received FDA approval in 2007.
How many antiretroviral drugs are there?
Currently, more than 30 antiretroviral drugs are available, including several fixed-dose combinations, which contain two or more medications from one or more drug classes in a single tablet. Today, many people control their HIV by taking as little as one pill once a day.
What is the primary co-receptor used by HIV?
A number of research groups, including NIAID scientists, determined that a different receptor called CCR5 is actually the primary co-receptor used by HIV to infect immune cells. This work laid the foundation for the development of the CCR5- blocking drug maraviroc, which received FDA approval in 2007.
When did saquinavir get FDA approval?
In December 1995, saquinavir became the first protease inhibitor to receive FDA approval. In 1996, results from an NIAID-sponsored trial showed that a three-drug regimen of saquinavir, ddC, and AZT was more effective than two-drug therapy with ddC and AZT. One of the key studies demonstrating the efficacy of triple-drug therapy was ACTG 320, ...

How does treatment help prevent HIV?
Having an undetectable viral load may also help prevent transmission from injection drug use.
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. HIV medicine can make the viral load very low (called viral suppression ). Viral suppression is defined as having less than 200 copies of HIV per milliliter of blood.
