Integrase strand transfer inhibitors (integrase inhibitors or integrases) stop HIV genes from becoming incorporated into the human cell’s DNA and are very well tolerated. Raltegravir (Isentress) was the first drug in this class. Elvitegravir is part of a fixed-dose combination (elvitegravir/cobicistat/tenofovir/emtricitabine) taken as one pill once daily, called Stribild. Dolutegravir (Tivicay) is also available in a once-daily combination pill with two NRTIs, abacavir and lamivudine, called Triumeq.

HIV attacks and destroys the infection-fighting CD4 cells of the immune system. The loss of CD4 cells makes it difficult for the body to fight infections and certain cancers. Without treatment, HIV can gradually destroy the immune system and advance to AIDS.

Additionally, people with AIDS frequently have systemic symptoms such as prolonged fevers, sweats (particularly at night), swollen lymph nodes, chills, weakness, and unintended weight loss.[39] Diarrhea is another common symptom, present in about 90% of people with AIDS.[40] They can also be affected by diverse psychiatric and neurological symptoms independent of opportunistic infections and cancers.[41]

A few exceptional patients can control their HIV strain without treatment; they maintain normal CD4 counts and very low blood levels of HIV (long-term nonprogressors) or normal CD4 counts and undetectable blood levels of HIV (elite controllers). These patients may not require ART, but studies to determine whether treating them is helpful have not been done and would be difficult because there are few of these patients and they would likely do well not taking ART for long periods.

In 2006, male circumcision was found to reduce the risk of female-to-male HIV transmission by 60%.81 Since then, the WHO and UNAIDS have emphasised that male circumcision should be considered in areas with high HIV and low male circumcision prevalence.82

Because human immunodeficiency virus (HIV) infection is incurable, preventing HIV transmission is paramount. Exposure to HIV can occur by percutaneous, mucous membrane or non-intact skin exposure to infected blood or body fluids. It can also occur by sexual contact, trauma or needle sharing. Postexposure prophylaxis (PEP) is one method of preventing HIV transmission. PEP is the provision of antiretroviral therapy (ART) to HIV-negative persons exposed to infected materials. It should be emphasized that PEP should not replace standard infection control measures and behavioral practices that best prevent HIV exposure.

Anything that weakens your immune system can lead to a secondary immunodeficiency disorder. For example, exposure to bodily fluids infected with HIV, or removing the spleen can be causes. Spleen removal may be necessary because of conditions like cirrhosis of the liver, sickle cell anemia, or trauma to the spleen.

These results provide a dramatic confirmation of experimental work suggesting that CCR5 is the major macrophage and T-lymphocyte co-receptor used by HIV to establish primary infection in vivo, and offers the possibility that primary infection might be blocked by therapeutic antagonists of the CCR5 receptor. Indeed, there is preliminary evidence that low molecular weight inhibitors of this receptor can block infection of macrophages by HIV in vitro. Such low molecular weight inhibitors might be the precursors of useful drugs that could be taken by mouth. Such drugs are very unlikely to provide complete protection against infection, as a very small number of individuals who are homozygous for the nonfunctional variant of CCR5 are infected with HIV. These individuals seem to have suffered from primary infection by CXCR4-using strains of the virus.

Regular blood tests are needed to make sure the virus level in the blood (viral load) is kept low, or suppressed. The goal of treatment is to lower the HIV virus in the blood to a level that is so low that the test can’t detect it. This is called an undetectable viral load.

It is important to document that an exposure has occurred or was likely. A needle stick from a person with HIV or a person likely to have HIV constitutes a significant exposure. Medications should be started immediately. If it is unknown whether the person who is the source of the potentially infected material has HIV, the source person can be tested. Medications that were started immediately in the exposed person can be discontinued if the source person does not turn out to carry HIV. Potentially infectious material splashed in the eye or mouth, or coming into contact with non-intact skin, also constitutes an exposure and should prompt immediate evaluation to determine if medications should be started.

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 . 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 . There is not cost to volunteers to participate and some medical care and testing is provided.

Merely having HIV does not mean a person has AIDS. AIDS is an advanced stage of HIV infection and requires that the person have evidence of a damaged immune system. That evidence comes from at least one of the following:

“Safe sex” practices, such as latex condoms, are highly effective in preventing HIV transmission. HOWEVER, there remains a risk of acquiring the infection even with the use of condoms. Abstinence is the only sure way to prevent sexual transmission of HIV.

Immunodeficiency describes the condition in which the body’s immune response is damaged, weakened, or is not functioning properly. In AIDS, immunodeficiency results from the way that the virus binds to a protein called CD4, which is primarily found on the surface of certain subtypes of white blood cells. After the virus has attached to the cell’s CD4 receptor, the virus-CD4 complex refolds to uncover another receptor called a chemokine receptor that helps mediate entry of the virus into the cell. One chemokine receptor in particular, CCR5, has been the focus of recent research after studies showed that defects in its structure (caused by genetic mutations) result in a slowing or stopping of the progression of AIDS. Scientists hope that this discovery will lead to the development of drugs that trigger an artificial mutation of the CCR5 gene or target the CCR5 receptor.

Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.

Treatment with HAART is not without complications. HAART is a collection of different medications, each with its own side effect profile. Some common side effects are nausea, headache, weakness, malaise, and fat accumulation on your back and abdomen (“buffalo hump,” lipodystrophy). When used long-term, these medications may increase the risk of heart attack by affecting fat metabolism.

GALT has been shown to be a site of early viral seeding and establishment of the proviral reservoir. This reservoir contributes to the difficulty of controlling the infection, and efforts to reduce the levels of HIV provirus through sustained antiretroviral therapy (alone or in combination with interleukin-2 activation of resting HIV-infected T cells) have consistently failed. [29]

In 2015, the reported rate of AIDS diagnoses in the United States was 5.7 per 100,000 population. [72] From 1981-2015, 1,216,917 persons were diagnosed with AIDS in the United States, and 678,509 people had died with AIDS by the end of 2014 (although reporting limitations mean that not every “death with AIDS” is directly attributable to AIDS itself).

HIV-positive patients who are taking anti-retroviral medications are less likely to transmit the virus. For example, pregnant women who are on treatment at the time of delivery transmit HIV to the infant about 5% of the time, compared to approximately 20% if medications are not used.

Although the American research Robert Gallo at the National Institutes of Health (NIH) believed he was the first to find HIV, it is now generally accepted that the French physician Luc Montagnier (1932-) and his team at the Pasteur Institute discovered HIV in 1983-84.

The humoral immune system is also affected. Hyperplasia of B cells in lymph nodes causes lymphadenopathy, and secretion of antibodies to previously encountered antigens increases, often leading to hyperglobulinemia. Total antibody levels (especially IgG and IgA) and titers against previously encountered antigens may be unusually high. However, antibody response to new antigens (eg, in vaccines) decreases as the CD4 count decreases.

Moreover never loose hope for life as is the only chance which we got, who knows about the second life, if got infected accediently do not loose hope and do the best u can do for yourself and the society.

First of all, there is no evidence that people infected with HIV can be cured by the currently available therapies, although research related to curing people of infection will be discussed later. In general, those who are treated for years and are repeatedly found to have no virus in their blood by standard viral load assays will experience a prompt rebound in the number of viral particles when therapy is discontinued. Consequently, the decision to start therapy must balance the risk versus the benefits of treatment. The risks of therapy include the short- and long-term side effects of the drugs, described in subsequent sections, as well as the possibility that the virus will become resistant to the therapy, which can limit options for future treatment. The risks of both of these problems are quite small with the treatment options currently available.

The human immunodeficiency virus (HIV) which causes acquired immune deficiency syndrome (AIDS) has brought about a global epidemic of massive proportions. HIV is a retrovirus and also the term often applied to the infection before the deterioration of the immune system to produce a full-blown picture of AIDS.

Health care professionals who fail to provide care to women who are infected with HIV because of personal practice preferences violate professional ethical standards. The public appropriately expects that health care practitioners will not discriminate based on diagnosis, provided that the patient’s care falls within their of practice. Physicians should demonstrate integrity, compassion, honesty, and empathy. Failure to provide health care to a woman solely because she is infected with HIV violates these fundamental characteristics. As with any other patient, it is acceptable, however, to refer women who are infected with HIV for care that the physician is not competent to provide or if care elsewhere would be more convenient or associated with decreased financial burden to the patient.
