Most PIs are associated with important drug-drug interactions so they must be used with caution in patients on other medications. There are numerous resources available to patients on these medications to make sure that they do not adversely interact with other HIV or non HIV-related drugs.

Fungi. The most common fungal disease associated with AIDS is Pneumocystis carinii pneumonia (PCP). PCP is the immediate cause of death in 15-20% of AIDS patients. It is an important measure of a patient’s prognosis. Other fungal infections include a yeast infection of the mouth (candidiasis or thrush) and cryptococcal meningitis.

Other potential exposures include vaginal and anal sexual intercourse and sharing needles during intravenous drug use. There is less evidence for the role of antiretroviral postexposure prophylaxis after these exposures. In part, this is because the HIV status of a sexual partner or drug user is not usually known by the exposed person. Nevertheless, the U.S. Centers for Disease Control and Prevention (CDC) recommends treatment for people exposed through sexual activity or injectable drug use to someone who is known to carry HIV. If the HIV status of the source is not known, the decision to treat is individualized. Concerned people should see their physician for advice. If a decision to treat is made, medications should be started within 72 hours of the exposure.

The human immunodeficiency virus (HIV) causes HIV infection and the acquired immunodeficiency syndrome (AIDS). Symptoms and signs of HIV infection include fatigue, enlarged lymph glands, and recurrent vaginal yeast infections. Highly active antiretroviral therapy (ART) is the standard treatment for HIV infection. Read more: Human Immunodeficiency Virus (HIV) Article

Without treatment, HIV infection to cause symptoms in an average of eight to 10 years with opportunistic illnesses, or diseases that only cause illness in people with impaired immune function. This symptomatic phase has been referred to as acquired immune deficiency syndrome (AIDS) or HIV disease.

Black Africans have traditionally been over-represented in this category. However, recent research suggests that up to a fifth of HIV infections among black African men initially classified as ‘heterosexual exposure’ in the UK are likely to have been acquired as a result of sex with other men.[8]

The profound immunosupression seen in AIDS is due to the depletion of T4 helper lymphocytes. HIV is present at a high level in the blood immediately after exposure. It then settles down to a certain low level set-point during the incubation period that lasts from 3-8 weeks. During the incubation perid, there is a massive turnover of CD4 cells as the CD4 cells killed by HIV are replaced rapidly and efficiently. The immune system eventually succumbs and AIDS is developed when killed CD4 cells can no longer be replaced, as witnessed by high HIV-RNA, HIV-Antigen and low CD4 counts.

In 1981, cases of a rare lung infection called Pneumocystis carinii pneumonia (PCP) were found in five young, previously healthy gay men in Los Angeles.2 At the same time, there were reports of a group of men in New York and California with an unusually aggressive cancer named Kaposi’s Sarcoma.3

Most people infected by HIV develop a flu-like illness within a month or two after the virus enters the body. This illness, known as primary or acute HIV infection, may last for a few weeks. Possible signs and symptoms include:

The accessory proteins of HIV-1 and HIV-2 are involved in viral replication and may play a role in the disease process. [21, 22] The outer part of the genome consists of long terminal repeats (LTRs) that contain sequences necessary for gene transcription and splicing, viral packaging of genomic RNA, and dimerization sequences to ensure that 2 RNA genomes are packaged.

Viral recombination produces genetic variation that likely contributes to the evolution of resistance to anti-retroviral therapy.[74] Recombination may also contribute, in principle, to overcoming the immune defenses of the host. Yet, for the adaptive advantages of genetic variation to be realized, the two viral genomes packaged in individual infecting virus particles need to have arisen from separate progenitor parental viruses of differing genetic constitution. It is unknown how often such mixed packaging occurs under natural conditions.[75]

Treating infected women with HIV drugs can dramatically reduce the risk of transmission. Infected pregnant women should be treated during the 2nd and 3rd trimesters of pregnancy, during delivery, and during breastfeeding. Doing a cesarean delivery and treating the baby for several weeks after birth also reduce the risk.

It appears that macrophage-tropic isolates of HIV are preferentially transmitted by sexual contact as they are the dominant viral phenotype found in newly infected individuals. Virus is disseminated from an initial reservoir of infected dendritic cells and macrophages and there is evidence for an important role for mucosal lymphoid tissue in this process. Mucosal epithelia, which are constantly exposed to foreign antigens, provide a milieu of immune system activity in which HIV replication occurs readily. Infection of CD4 T cells via CCR5 occurs early in the course of infection and continues to occur, with activated CD4 T cells accounting for the major production of HIV throughout infection. Late in infection, in approximately 50% of cases, the viral phenotype switches to a T-lymphocyte-tropic type that utilizes CXCR4 co-receptors, and this is followed by a rapid decline in CD4 T-cell count and progression to AIDS.

The CDC reported that, at the end of 2014, the most recent year for which national prevalence statistics are available, there were 955,081 adults and adolescents living with HIV infection in the United States, 521,002 of whom had infection classified as stage 3 (AIDS). [72]

HIV-1 testing is initially done using an enzyme-linked immunosorbent assay (ELISA) to detect antibodies to HIV-1. Specimens with a non-reactive result from the initial ELISA are considered HIV-negative unless new exposure to an infected partner or partner of unknown HIV status has occurred. Specimens with a reactive ELISA result are retested in duplicate.[105] If the result of either duplicate test is reactive, the specimen is reported as repeatedly reactive and undergoes confirmatory testing with a more specific supplemental test (e.g., a polymerase chain reaction (PCR), western blot or, less commonly, an immunofluorescence assay (IFA)). Only specimens that are repeatedly reactive by ELISA and positive by IFA or PCR or reactive by western blot are considered HIV-positive and indicative of HIV infection. Specimens that are repeatedly ELISA-reactive occasionally provide an indeterminate western blot result, which may be either an incomplete antibody response to HIV in an infected person or nonspecific reactions in an uninfected person.[106]

The Centers for Disease Control has defined AIDS as beginning when a person with HIV infection has a CD4 cell (also called “t-cell”, a type of immune cell) count below 200. It is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection.

Because the recommended population for HIV testing includes adolescents, it also is important to have practices in place to assist young patients. This includes a process of discussing safe-sex practices, risk factors, and behavior that may lead to HIV exposure. Currently, some states allow minors to access HIV testing in a confidential fashion without disclosing testing or results to a parent or guardian (9, 10). However, there are others that require some degree of notification or consent from a parent before testing. It is important for Fellows to be aware of the local policies in place and to fulfill the legal and ethical obligations to their adolescent patients who seek HIV testing as part of their reproductive health care. The Guttmacher Institute maintains an updated list of minors’ consent state policies (www.guttmacher.org/statecenter/spibs/spib_OMCL.pdf).

The other issue raised by these studies is the effect of HIV replication on the population dynamics of CD4 T cells. The decline in plasma viremia is accompanied by a steady increase in CD4 T lymphocyte counts in peripheral blood: what is the source of the new CD4 T cells that appear once treatment is started? It seems highly unlikely that they are the recent progeny of stem cells that have developed in the thymus, because CD4 T cells are not normally produced in large numbers from the thymus even at its maximum rate of production in adolescents. Some investigators believe that these cells are emerging from sites of sequestration and add little to the total numbers of CD4 T cells in the body, whereas others advocate their origin from mature CD4 T cells that replicate, and argue that the production of such cells is an ongoing process that compensates for the continual loss of productively infected CD4 T cells.

HIV can be suppressed by combination ART consisting of 3 or more ARV drugs. ART does not cure HIV infection but suppresses viral replication within a person’s body and allows an individual’s immune system to strengthen and regain the capacity to fight off infections.

Key populations are groups who are at increased risk of HIV irrespective of epidemic type or local context. They include: men who have sex with men, people who inject drugs, people in prisons and other closed settings, sex workers and their clients, and transgender people.

HIV infects vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells.[8] HIV infection leads to low levels of CD4+ T cells through a number of mechanisms, including pyroptosis of abortively infected T cells,[9] apoptosis of uninfected bystander cells,[10] direct viral killing of infected cells, and killing of infected CD4+ T cells by CD8+ cytotoxic lymphocytes that recognize infected cells.[11] When CD4+ T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body becomes progressively more susceptible to opportunistic infections, leading to the development of AIDS.

HIV stands for human immunodeficiency virus. It weakens a person’s immune system by destroying important cells that fight disease and infection. No effective cure exists for HIV. But with proper medical care, HIV can be controlled. Some groups of people in the United States are more likely to get HIV than others because of many factors, including their sex partners, their risk behaviors, and where they live. This section will give you basic information about HIV, such as how it’s transmitted, how you can prevent it, and how to get tested for HIV.

  1. HIV positive women should be counseled before becoming pregnant about the risk to unborn children and medical advances which may help prevent the fetus from becoming infected. Use of certain medications can dramatically reduce the chances that the baby will become infected during pregnancy.

    Drug treatment guidelines for HIV/AIDS change frequently as new drugs are approved and new drug regimens developed. Two principles currently guide doctors in developing drug regimens for AIDS patients: using combinations of drugs rather than one medication alone; and basing treatment decisions on the results of the patient’s viral load tests. Current information on United States Food and Drug Administration-(FDA)approved drugs by class can be found at the United States Department of Health and Human Services Aids Info Website at < http://www.aidsinfo.nih.gov/DrugsNew/Default.aspx?MenuItem=Drugs>. Individuals interested in participating in a trial of new HIV/AIDS drugs under development can find a list of clinical trials currently accepting volunteers at < http://www.clinicaltrial.gov>. There is not cost to volunteers to participate and some medical care and testing is provided.
