Introduction to HIV - HIV Treatment

Written by Brian Boyle, MD, JD

HIV Treatment

In the time between initial infection and AIDS, the infected person may feel relatively normal, despite the constant attack by HIV. People living with HIV have to understand, however, that despite feeling well on the outside, significant damage can be occurring on the inside. Fortunately, over the past five years, significant progress has been made regarding the treatment of HIV and prevention of some of the infections and cancers that may be caused by it. Antiretroviral medications can directly attack HIV and stop it from reproducing and causing further damage. For most people, the biggest factor in preventing progression to AIDS is adherence to HAART, which can suppress HIV replication to very low levels and not allow it to continue to attack the body.

Prophylactic medications In addition to HAART, other steps can be taken to prevent illness in people living with HIV and AIDS. Certain antibiotics, called prophylactic medications, can effectively prevent opportunistic infections. A physician can help to assess the appropriateness of these medications in a particular treatment program, and which ones to use, but it is important that they be taken as prescribed so that infections can be prevented. With careful monitoring, OIs and certain cancers can be detected in their early stages before they have spread, and the antibiotics can work more effectively to ward off further serious complications. I recommend that every person living with HIV or AIDS see a physician for appropriate monitoring and treatment.

Who Should be Tested for HIV?

In the early 1980s, when HIV infections were first starting to appear, HIV was associated primarily with gay men. Then it became associated with intravenous drug users and hemophiliacs. During the past 20 years, however, HIV has become a disease that can affect almost anyone who is not monogamous with an uninfected person.

HIV contraction

HIV is contracted through an exchange of bodily fluids, such as blood, semen, or vaginal secretions. As a result, the most common ways of acquiring HIV are sharing needles while doing intravenous drugs, and sex, especially anal intercourse. While the highest risk of HIV transmission is associated with anal intercourse, vaginal intercourse is becoming a common means of spreading HIV. Vaginal intercourse is the most rapidly growing risk factor for acquiring HIV infection in the United States and in the developing world it is the most common method of HIV transmission. Everyone must take appropriate steps to prevent the spread of HIV: Safer sex with condoms and dental dams and not sharing needles can help prevent the spread of HIV.

Common misconceptions about HIV contraction

People are often concerned that HIV can be contracted through common contacts with an HIV-infected person, such as shaking hands or sharing glasses or eating utensils. These are not risk factors for contracting HIV. There is no evidence that HIV can be spread through these means, and people should not be afraid to be around people who have HIV or to use a glass, eating utensils, or plate that an HIV-infected person has used, or to have other common contacts.

Those who should consider being tested for HIV include:

• people who received a blood transfusion or blood product at any time, but especially in the late 1970s or 1980s
• homosexuals and heterosexuals who have a history of unprotected sex with potentially infected persons
• people who have had multiple sex partners
• people who have had a sexually transmitted disease such as syphilis or gonorrhea
• people who are intravenous drug users
• pregnant women

The importance of testing and diagnosis

The importance of HIV testing and diagnosis has increased over the past five years. Before the improvements in antiretroviral therapies, many people believed that there was little that could be done to prevent the progression of HIV and so they did not get tested. While these people were right about the ineffectiveness of the antiretroviral therapy available at that time, they failed to recognize that medicines had been discovered that could prevent many of the common infections that afflict AIDS patients. Thus, many people were diagnosed with HIV only after they were admitted to the hospital with severe infections, especially PCP. Some died needlessly because they had not sought appropriate medical care and did not receive one of the medications that could have prevented PCP from occurring.

Now, there are even more reasons to seek HIV testing and medical care. Within the past five years, the medicines to prevent infections have been significantly improved and effective antiretroviral therapies have been developed that can not only halt the progression of HIV, but can also reverse much of the damage that has already been done. Therefore, it is important that HIV is diagnosed while the person is relatively healthy and before a major, potentially life-threatening OI occurs, such as PCP or cerebral toxoplasmosis. With HIV, what you don't know can hurt you.
