Anti Aids Drug AZT: How it Works Many viruses around through our environment have the capability to infect and reproduce in humans, sometime quickly being able to spread over a substantial amount of the population. HIV is a retrovirus which advances into AIDS, and it has infected people worldwide, most prevalently in Africa. Retroviruses are able to replicate, and do this by duplicating their genetic information through reverse transcription. With this rise in infected by AIDS in the past 30 year extensive research has been done in the medical field in order to combat this virus. AZT chemical name 3’-azido-3’-deoxythymidine, is an anti AIDS drug which is works by inhibiting the reverse transcription process (Adlam, 2013). The further understanding of how AZT works is crucial in order to find out exactly what it does to our bodies and the virus HIV’s ability to develop resistance to this anti HIV drug. 3’-azido-3’-deoxythymidine has been used as an anti AIDS drugs thought the world and is a part of the group of drugs called nucleoside reverse transcriptase inhibitors. The retrovirus that causes HIV and develops into AIDS does so through a process known as reverse transcription. Reverse transcription is a process used in order to convert RNA into viral DNA, so the virus can replicate itself and spread (Adlam, 2013). Reverse transcription relies on the enzyme reverse transcriptase in order to begin and proceed. AZT blocks the binding of the enzyme reverse transcriptase, if the enzyme cannot bind, the process cannot proceed, and therefore the virus cannot replicate itself and spread (Matthews,2013). This does not kill the virus; however it inhibits it from spreading thought the body. Due to this fact this drug has a very practical application among pregnant women infected with the HIV virus. It can aid in

Patient Teaching—prevention of secondary infection, hand hygiene, decrease risk of infection at home, NO cats. Nursing Implications—prevent secondary infection, prevent wasting syndrome from malnutrition, maintain or improve the present level of immune function, maintain adequate social functioning, and maintain or improve current mental status. HIV-1 and HIV-2 are both retroviruses and have only RNA as their genetic material. When they replicate their genetic material is placed in the DNA of the host cell. Risk Factors—contact with body fluids, sex…etc.. Sentinel Infection—opportunistic infections that indicate immunosuppression, appears as oral thrush, recurrent vaginal yeast infections, or skin disorders. NNRTIs/PIs Action—Nonnucleoside Reverse Transcriptase Inhibitors act by binding to and disabling reverse transcriptase, a protein that is needed for replication of HIV. Protease Inhibitors work on the last stage of viral production cycle by preventing the virus from maturing and cause the release of immature viruses, which are then unable to infect other host cells. Needlestick Treatment—notify infection control officer, 2-drug or 3-drug therapy must be taken for 4-6 weeks. CD4 Count—A diagnosis of AIDS is usually made in a HIV-infected patient with a CD4 T-lymphocyte count less than 200cells/uL or with a specific opportunistic infection being diagnosed.…

    Following the discovery, the first test for HIV was approved in 1985. Over the years, medications to combat the virus were developed as well as medicine to prevent infection all without a successful result. HIV/AIDS remain one of the greatest health and social problem threatening humanity. The basic biology of the virus from inside out include RNA which contains all of its genetic information, a key enzymes it uses to replicates (reverse transcriptase) and a binding proteins that allow it to binds to human cell, (USAID,2007).…

    Robert Gallo and his colleagues had isolated the retrovirus HTLV-III and a diagnostic blood test was well into development. Less than a year later, FDA licenses HIV blood tests for sale (CDC).This was a momentous achievement; in such a short time the scientific community had persevered against this faceless, mysterious threat and were making progress. Prior to this, the scientific community saw viral infections as impossible to treat, and not serious enough to finance thorough research for a cure (Zurger). “Immunologists now have a far better understanding of the primary immune cells called T-lymphocytes that the virus particularly strikes [...] and the complex links between cancer, immunity and infection have also been cemented by findings in H.I.V.-infected people” (Zurger). The field of retrovirology was born; scientists were able to gain from the massive inflow of data collected over the next years how retroviruses alter the DNA of their host cells, how they evade immune detection, and were able to draw parallels between the spread of cancer and and spread of HIV infection. This provided the necessary context for inferences on the bases for RNA genetic code, sparking research that was able to assess and explain the function of reverse transcriptase (Broder). In 1985, the first treatment for HIV/AIDS, Zidovudine (commonly referred to as AZT), was sold and several wellness programs…

    Protease inhibitors can be used in medicine to treat different diseases and viruses which depend on protease for its mechanism of action. Protease inhibitors are most commonly used in the treatment of HIV/AIDS. Protease is responsible for the synthesis of new viral cells which would cause HIV to spread to uninfected cells. When the protease is introduced however, non-infectious vial particles are produced. The protease involved in HIV is called the HIV protease which is an aspartic protease (San Francisco General Hospital,…

    Human Immunodeficiency Virus (HIV) is a virus that affects the human immune system and leads to a stat makes the patient unable to fight against diseases and so opportunistic diseases such Tuberculosis and others affect the individual (Worthington et al., 2010). HIV/AIDS was first realized in 1981 by the Center for Disease Control and Prevention and is believed to have originated from West-Central Africa. HIV/AIDS has been termed as one of the greatest causes of death in the global society (Gibbs, 2010). The virus is spread when body fluids of a victim gets into contact with the body fluids of another person. Due to the nature of the disease, even unsuspecting individuals such as patients undergoing blood transfusion, unborn babies and others can become victims. HIV is primarily spread through sexual intercourse without any form of protection (Ford et al., 2007; Gardezi et al., 2008).…

    Therefore, in the nucleus of the cell, viral DNA polymerase, responsible for adding in nucleotides (“A”, “G”, “C”, “T”), will recognize acyclovir triphosphate as deoxyguanosine triphosphate (a “G” base) and by mistake will incorporate the acyclovir triphosphate into the growing DNA strand. Further elongation of the chain is impeded as acyclovir triphosphate lacks the attachment site necessary for the insertion of any additional nucleotides. Thus acyclovir triphosphate inhibits viral DNA polymerase by acting as an analog to deoxyguanosine triphosphate and as a consequence terminates the growth of the viral DNA within the ‘infected’ cell. Without affecting the normal cellular process, the anti-viral prevents the virus from multiplying and controls the spread of the infection.…

    HIV illness signifies a continuum of infection that starts with a concise severe retroviral disease that normally changes to a long-lasting and pathologically dormant infection. If treatment is not provided right away this disease in the end develops to immunodeficiency disease identified as AIDS. If left untreated the period connecting the HIV Illness and the progression of AIDS fluctuates, alternating from a couple months to several years with a projected average period of roughly 11 years (CDC, 2011). Research displays that the viruses are taking an increasing toll on girls and women in the United States. The statistics showed women with AIDS rise 8% to 27% from 1985 to 2005 and these figures are even larger worldwide…

    HIV/AIDS is one of the deadliest diseases in the world. Although millions of people are afflicted with the disease throughout the world, this pandemic affects the continent of Africa the most by far. In Africa, the disease is increasing at an alarming rate. Even though increased effort is put in around the world to prevent AIDS, this widespread disease has increased significantly in the past decade. The toxic ailment continues to spread with a disturbing force and it has taken a long time to finally slow it down. In the late 2000’s, approximately 40 million people around the world were living with AIDS or the HIV infection, a significant rise from the 35 million diagnosed with AIDS in 2001 (Bertozzi). Sub-Saharan Africa remains the region most impacted by the HIV virus; however, the disease is now growing and spreading into different continents such as Asia and countries in Eastern Europe as well as other parts of Africa.…
