If HIV infection is suspected despite negative antibody test results (eg, during the first few weeks after infection), the plasma HIV RNA level may be measured. The nucleic acid amplification assays used are highly sensitive and specific. HIV RNA assays require advanced technology, such as reverse transcription–PCR (RT-PCR), which is sensitive to extremely low HIV RNA levels. Measuring p24 HIV antigen by ELISA is less sensitive and less specific than directly detecting HIV RNA in blood.
Patients with late-stage AIDS may develop Kaposi’s sarcoma (KS), a skin tumor that primarily affects homosexual men. KS is the most common AIDS-related malignancy. It is characterized by reddish-purple blotches or patches (brownish in people with dark skin) on the skin or in the mouth. About 40% of patients with KS develop symptoms in the digestive tract or lungs. KS may be caused by a herpes virus-like sexually transmitted disease agent rather than HIV.
There is less information on the effectiveness of PEP for people exposed via sexual activity or intravenous drug use — however, if you believe you have been exposed, you should discuss the possibility with a knowledgeable specialist (check local AIDS organizations for the latest information) as soon as possible. All rape victims should be offered PEP and should consider its potential risks and benefits in their particular case.
Stevens-Johnson syndrome (SJS) is a rare allergic reaction to HIV medication. Symptoms include fever and swelling of the face and tongue. Rash, which can involve the skin and mucous membranes, appears and spreads quickly.
People with AIDS have had their immune system damaged by HIV. They are at very high risk of getting infections that are uncommon in people with a healthy immune system. These infections are called opportunistic infections. These can be caused by bacteria, viruses, fungi, or protozoa, and can affect any part of the body. People with AIDS are also at higher risk for certain cancers, especially lymphomas and a skin cancer called Kaposi sarcoma.
Macrophages. Tissue macrophages are one of the target cells for HIV. These macrophages harbour the virus and are known to be the source of viral proteins. However, the infected macrophages are shown to lose their ability to ingest and kill foreign microbes and present antigen to T cells. This could have a major contribution in overall immune dysfunction caused by HIV infection.
It is best practice to also retest all people initially diagnosed as HIV-positive before they enrol in care and/or treatment to rule out any potential testing or reporting error. Notably, once a person diagnosed with HIV and has started treatment they should not be retested.
Mortality from HIV disease has not been among the 15 leading causes of death in the US since 1997. The age-adjusted death rate for HIV disease peaked in 1995 at 16.3 per 100,000 population, decreased 69.9% through 1998, then further decreased 30.2% from 1999 through 2007, to 3.7 per 100,000 population. In 2007, a total of 11,295 persons died from HIV disease. However, HIV disease has remained among the 5 leading causes of death for specific age groups for females, and in the black population. 
As opposed to treating infected people to protect their uninfected partners, another approach is to provide antiviral treatment to uninfected individuals, so-called pre-exposure prophylaxis (PrEP). The first success in this research arena came from the CAPRISA 004 study, which showed that vaginal administration before and after intercourse of a gel containing the antiretroviral agent tenofovir reduced the risk of transmission of both HIV and herpes simplex virus to heterosexual women. Other studies are under way to confirm the results of this study as well as to determine whether the results are any different if the agent is administered daily rather than simply around the time of intercourse. One such study was not be able to show that once-daily tenofovir vaginal gel demonstrated protection from infection compared to placebo gel. The reasons for this finding are not completely known, but it does appear that adherence with the therapy was very poor.

There is an emerging consensus that indications for reproductive technology use should not vary with HIV serostatus; therefore, assisted reproductive technology should be offered to couples in which one or both partners are infected with HIV. This approach is consistent with the principles of respect for autonomy and beneficence (18, 19). In addition, those who advocate providing these services cite three clinical arguments to support their position:
Sleep is very important for a healthy immune system. According to the Mayo Clinic, adults need about eight hours of sleep per night. It’s also important that you stay away from people who are sick if your immune system isn’t working properly.
Scientists have also learned that if a city has a needle exchange program it will have fewer people who use illegal drugs. Needle exchange programs are where people can come in and trade dirty needles for clean needles. This means that if they use drugs they will be more safe. But needle exchange programs do more than give people clean needles. They teach people about drugs. If people want to stop using drugs, they help them.

Mother-to-child transmission is the most common way that children become infected with HIV. HIV medicines, given to women with HIV during pregnancy and childbirth and to their babies after birth, reduce the risk of mother-to-child transmission of HIV.

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.

HIV stands for Human Immunodeficiency Virus. It’s a virus that breaks down certain cells in your immune system (your body’s defense against diseases that helps you stay healthy). When HIV damages your immune system, it’s easier to get really sick and even die from infections that your body could normally fight off.

Pneumonia is inflammation of the lungs caused by fungi, bacteria, or viruses. Symptoms and signs include cough, fever, shortness of breath, and chills. Antibiotics treat pneumonia, and the choice of the antibiotic depends upon the cause of the infection.
The recent report of the so-called “Berlin patient” has stimulated a great deal of interest. This HIV-infected man had leukemia, which was treated with a bone marrow transplant. His health care providers were able to identify a tissue-matched donor who happened to be one of the rare individuals who carried a genetic defect resulting in the lack of CCR5 on the surface of their cells. CCR5 is required for certain types of HIV to enter the cells, and these unique individuals are relatively resistant to infection. After the bone marrow transplant, the patient was able to stop antiretroviral therapy and for years has not had detectable HIV in his body. It is worth noting that this individual experienced far more than the engraftment of unique bone marrow. He underwent intensive chemotherapy and radiation treatment to destroy most immune cells in the body, as well as graft-versus-host disease, which could also further destroy residual HIV-infected cells. Together these events could have markedly reduced the reservoir of virus that persists in the body of all infected individuals, which could have facilitated the purported “cure” or set the stage for the ultimate success associated with the engraftment of the unique bone marrow. There was recently excitement about two individuals who underwent so-called “stem cell transplants” but without the unique donor that was used by the Berlin patient. While virus remained at very low levels in these individuals while on therapy, at three and eight months after treatment interruption, HIV came storming back. Consequently, the experience with the Berlin patient has not yet been replicated and, even if it is, will not be an option for most people. First, bone marrow transplants are associated with very high risk of illness and death, and second, very few patients who need a bone marrow transplant for any reason are likely to find a tissue-matched donor who carries this rare genetic mutation. However, research is pursuing the potential role each part of this individual’s treatment may have had on the successful control of HIV off therapy, as well as working on ways to genetically engineer an individual’s own blood CD4 cells or stem cells to not have the CCR5 molecule. While this research is in the very early stages of development, it certainly provides hope for the future of research related to HIV eradication and/or cure.
Health care workers are at risk on the job and should take special precautions. Some health care workers have become infected after being stuck with needles containing HIV-infected blood or less frequently, after infected blood comes into contact with an open cut or through splashes into the worker’s eyes or inside their nose.
A ripple effect among cohorts of women that may deter other women at risk from accepting testing and have a serious negative impact on the educational efforts that lie at the heart of attempts to reduce the spread of disease
Dr. Daar received his undergraduate degree from UCLA and medical degree from Georgetown University School of Medicine. He completed an internship and residency in internal medicine at Cedars-Sinai Medical Center and his clinical and research fellowship in infectious diseases at Cedars-Sinai Medical Center and UCLA.
There has been a great deal of attention given to the more recently identified problem of “lipodystrophy.” Individuals suffering from this syndrome can be categorized as having lipohypertrophy (fat accumulation) syndromes, such as the “buffalo hump” on the back of the neck, breast enlargement, or increased abdominal girth. Others primarily suffer from lipoatrophy with fat loss under the skin with complaints of prominent veins on the arms and legs, sunken cheeks, and decreased gluteal (buttock) size. These syndromes appear to be related to multiple factors, including, but not limited to, drug therapy. The NRTIs appear to be most closely linked to lipoatrophy, in particular D4T and to a lesser extent ZDV. In fact, some studies have suggested slow accumulation of fat in those who modify the NRTI component of their regimen. Some NRTIs also have been linked to elevation in lipid (fat) levels in the blood. While switching therapy is always a consideration in those experiencing potential drug-related toxicity, this should only be done under the careful supervision of an experienced HIV provider.
