In addition to the CD4 lymphocyte count, chest X-rays, Pap smears, and other tests are useful in managing HIV disease. Gay men who engage in receptive anal sex may wish to consider anal Pap smears to detect potential cancers.
PEP is short for post-exposure prophylaxis and refers to preventive treatment after occupational exposure to HIV. Occupational transmission of HIV to health-care workers is extremely rare, and the proper use of safety devices minimizes the risk of exposure while caring for patients with HIV. A health-care worker who has a possible exposure should see a doctor immediately. PEP must be started within 72 hours after a recent possible exposure to HIV. While PEP after occupational exposure is clearly defined by guidelines, it is less clear whether PEP is as effective after sexual or IV exposure.

The group turned toward Benjamin Jennings, who wore a serious expression, with a shock of long hair in dreadlocks flipped to the side. When he said it was his first time there, everyone clapped. “I was diagnosed July 8 of this year, and my goal is to learn everything that I can about this thing,” said Jennings, 21, talking in a tumble of words as he pulled at his cropped T-shirt. “The first person I told was my mom. Thank God — I am so lucky to have her in my life.” He paused, looking into the faces of the men around the table and speaking more slowly. “I used to keep my feelings bottled up, but then I started opening my mouth on it,” he said. “I did everything to prevent this disease, but because of one slip-up I have it. Now I want to help anyone I can in any type of way. My goal is to not to let anyone judge me or let this disease own me.”

A small group of individuals continue to dispute the connection between HIV and AIDS, the existence of HIV itself, or the validity of HIV testing and treatment methods. These claims, known as AIDS denialism, have been examined and rejected by the scientific community. However, they have had a significant political impact, particularly in South Africa, where the government’s official embrace of AIDS denialism (1999–2005) was responsible for its ineffective response to that country’s AIDS epidemic, and has been blamed for hundreds of thousands of avoidable deaths and HIV infections.
HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body. This damage to the immune system makes it harder and harder for the body to fight off infections and some other diseases. Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. Learn more about the stages of HIV and how to know whether you’re infected.
Mutations that occur as HIV replicates can allow variants of the virus to escape recognition by antibody or cytotoxic T cells and can contribute to the failure of the immune system to contain the infection in the long term. Direct escape of virus-infected cells from killing by cytotoxic T lymphocytes has been shown by the occurrence of mutations of immunodominant viral peptides presented by MHC class I molecules. In other cases, variant peptides produced by the virus have been found to act as antagonists (see Section 6-12) for T cells responsive to the wild-type epitope, thus allowing both mutant and wild-type viruses to survive. Mutant peptides acting as antagonists have also been reported in hepatitis B virus infections, and similar mutant peptides might contribute to the persistence of some viral infections, especially when, as often happens, the immune response of an individual is dominated by T cells specific for a particular epitope.
The only drug in this class is T-20, which is administered as a twice-daily subcutaneous injection. The most common side effects are redness and pain at the site of injection. Rarely, infection can occur at the injection site. There also are reports of generalized allergic reactions.
These drugs prevent HIV from replicating in cells and dramatically reduce the amount of HIV in the blood over a few days to weeks. If replication is sufficiently slowed, the destruction of CD4+ lymphocytes by HIV is decreased and the CD4 count begins to increase. As a result, much of the damage to the immune system caused by HIV can be reversed. Doctors can detect this reversal by measuring the CD4 count, which begins to return toward normal levels over weeks to months. The CD4 count continues to increase for several years but at a slower rate.
Although one goal of antiviral therapy is to prevent the development of immune suppression, some individuals are already immunosuppressed when they first seek medical care. In addition, others may progress to that stage as a result of resistance to antiviral drugs. Nevertheless, every effort must be made to optimize antiviral therapy in these patients. In addition, certain specific antibiotics should be initiated, depending on the number of CD4 cells, to prevent the complications (that is, the opportunistic infections) that are associated with HIV immunosuppression. Guidelines for the prevention of opportunistic infections can be found at https://aidsinfo.nih.gov/.

Improving access to quality health care for populations disproportionately affected by HIV, such as people of color and gay and bisexual men, is a fundamental public health strategy for HIV prevention. People getting care for HIV can receive:
Returning to work after beginning treatment for HIV/AIDS is difficult, and affected people often work less than the average worker. Unemployment in people with HIV/AIDS also is associated with suicidal ideation, memory problems, and social isolation; employment increases self-esteem, sense of dignity, confidence, and quality of life. A 2015 Cochrane review found low-quality evidence that antiretroviral treatment helps people with HIV/AIDS work more, and increases the chance that a person with HIV/AIDS will be employed.
Vaccines against HIV have been difficult to develop because HIV surface proteins mutate easily, resulting in an enormous diversity of antigenic types. Nonetheless, various vaccine candidates are under study, and a few have shown promise in clinical trials. At the present time, there is no effective AIDS vaccine.
