Deborah Persaud (born 23 August 1960) is a Guyanese-born American virologist who primarily works on HIV/AIDS at Johns Hopkins Children's Center.
Persaud was born on 23 August 1960 in Port Mourant, East Berbice-Corentyne, Guyana to an Indo-Guyanese family. At age 16 she moved to Brooklyn. Persaud attended the New York University School of Medicine after receiving her undergraduate degree from York College CUNY. [1] She also earned a master's degree at the New York University School of Medicine. She started residency at the Babies Hospital of New York and finished her chief residency at the same hospital. Persaud later was a fellow at the New York University School of Medicine. She began her academic career as an assistant professor of pediatrics at the Johns Hopkins University School of Medicine from 1997 to 2004. In 2005, Persaud became an associate professor of pediatrics at the Johns Hopkins University School of Medicine.
The main topic of Persaud's research is AIDS and HIV of children. However, her research started from research about HIV in adults. In 2003, she stated about the human immunodeficiency virus (HIV)- type1 included in the subtypes of HIV. For the HIV patient, the HAART (highly active antiretroviral therapy) is used as treatment. The HAART regimen includes some drugs containing nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitor (PI), and non-nucleoside reverse transcriptase inhibitors (NNRTI). [2] The HAART has important function to suppress the levels of HIV-1 to below quantification. HIV-1 persists in cellular reservoirs of CD4+ continually with low-level viremia in adults, and this is very sensitive. Persaud and her research team found that viremia persists in children with plasma virus remaining at a level under the limit of detection of clinical assays. [3] When children with HIV-1 receive HAART treatment, the viremia that is difficult to observe is continued virus production without resistance in the protease gene. [4] Persaud's research team tried to find a novel culture assay that can stimulate the virus production during their latent, integrated HIV-1 in resting CD4+ T cells with the antiretroviral drugs. These drugs interfere with the replication of unintegrated virus. They also demonstrated the facts that HIV-1 polymerase sequences from the resting CD4+ T cells of the patients. [5] By following this research, her research topic has been about antiretroviral therapy. In 2009, her research team focused on the ongoing human immunodeficiency virus type 1 (HIV-1). From this research, it was figured out ongoing virus replication contributes to low-level viremia in patients on HAART, and this ongoing replication is subject to CD8+ T-cell selective pressure. After that, she suggested the induction therapy by using protease-inhibitors has influenced the effect of NNRTI (non-Nucleoside reverse transcriptase inhibitors) resistance on virologic response to nevirapine-based HAART in children patients of HIV. For a long time, her research topic has been focusing on the therapy of HIV-1 especially with the child patients. In order to develop the therapy, she has been explained about the mechanism using the NNRTI of HAART. [6]
In 2013 Persaud worked as part of a team who showed that a baby had been cured of HIV by giving it anti-HIV drugs; she won the Elizabeth Glaser Scientist Award and was featured in Time magazine's list of the 100 most influential people in 2013. [7] [8] [9] [10] She was also included in Nature's 10 for 2013, by the journal Nature . [11] In 2014 Persaud's work contributed to a second baby being cured of HIV. [12]
Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine. It can be used by mouth or by slow injection into a vein.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
Reverse-transcriptase inhibitors (RTIs) are a class of antiretroviral drugs used to treat HIV infection or AIDS, and in some cases hepatitis B. RTIs inhibit activity of reverse transcriptase, a viral DNA polymerase that is required for replication of HIV and other retroviruses.
Nevirapine (NVP), sold under the brand name Viramune among others, is a medication used to treat and prevent HIV/AIDS, specifically HIV-1. It is generally recommended for use with other antiretroviral medications. It may be used to prevent mother to child spread during birth but is not recommended following other exposures. It is taken by mouth.

Efavirenz (EFV), sold under the brand names Sustiva among others, is an antiretroviral medication used to treat and prevent HIV/AIDS. It is generally recommended for use with other antiretrovirals. It may be used for prevention after a needlestick injury or other potential exposure. It is sold both by itself and in combination as efavirenz/emtricitabine/tenofovir. It is taken by mouth.

A resistance mutation is a mutation in a virus gene that allows the virus to become resistant to treatment with a particular antiviral drug. The term was first used in the management of HIV, the first virus in which genome sequencing was routinely used to look for drug resistance. At the time of infection, a virus will infect and begin to replicate within a preliminary cell. As subsequent cells are infected, random mutations will occur in the viral genome. When these mutations begin to accumulate, antiviral methods will kill the wild type strain, but will not be able to kill one or many mutated forms of the original virus. At this point a resistance mutation has occurred because the new strain of virus is now resistant to the antiviral treatment that would have killed the original virus. Resistance mutations are evident and widely studied in HIV due to its high rate of mutation and prevalence in the general population. Resistance mutation is now studied in bacteriology and parasitology.
Etravirine is a drug used for the treatment of HIV. Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). Unlike the currently available agents in the class, resistance to other NNRTIs does not seem to confer resistance to etravirine. Etravirine is marketed by Janssen, a subsidiary of Johnson & Johnson. In January 2008, the Food and Drug Administration approved its use for patients with established resistance to other drugs, making it the 30th anti-HIV drug approved in the United States and the first to be approved in 2008. It was also approved for use in Canada on April 1, 2008.
Rilpivirine, sold under the brand names Edurant and Rekambys, is a medication, developed by Tibotec, used for the treatment of HIV/AIDS. It is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with higher potency, longer half-life and reduced side-effect profile compared with older NNRTIs such as efavirenz.
HIV disease–related drug reaction is an adverse drug reaction caused by drugs used for the treatment of HIV/AIDS.
Non-nucleoside reverse-transcriptase inhibitors (NNRTIs) are antiretroviral drugs used in the treatment of human immunodeficiency virus (HIV). NNRTIs inhibit reverse transcriptase (RT), an enzyme that controls the replication of the genetic material of HIV. RT is one of the most popular targets in the field of antiretroviral drug development.

Discovery and development of nucleoside and nucleotide reverse-transcriptase inhibitors began in the 1980s when the AIDS epidemic hit Western societies. NRTIs inhibit the reverse transcriptase (RT), an enzyme that controls the replication of the genetic material of the human immunodeficiency virus (HIV). The first NRTI was zidovudine, approved by the U.S. Food and Drug Administration (FDA) in 1987, which was the first step towards treatment of HIV. Six NRTI agents and one NtRTI have followed. The NRTIs and the NtRTI are analogues of endogenous 2´-deoxy-nucleoside and nucleotide. Drug-resistant viruses are an inevitable consequence of prolonged exposure of HIV-1 to anti-HIV drugs.
