This study compares 2 different anti-HIV drug regimens to determine which is the most effective in lowering the amount of HIV in the blood. The anti-HIV drugs used in this study are 2 protease inhibitors (nelfinavir and ritonavir), 2 nucleoside reverse transcriptase inhibitors (stavudine and didanosine), and 1 nonnucleoside reverse transcriptase inhibitor (nevirapine). These drug combinations have been previously studied in adults, but there is limited information on how well they work in HIV-infected children. It is important to develop drug combinations which are effective at suppressing the HIV virus in children.
The purpose of this study is to see if nonoxynol-9 (N-9) gel used in the vagina can prevent the spread of HIV. Most of the people with HIV in the world today live in southern Africa. Because this population is not likely to use condoms, an HIV-prevention method that women can control is needed. N-9 used in the vagina may help prevent the spread of HIV and other sexually transmitted diseases.
The purpose of this study is to see if it is safe to use BufferGel in the vaginas of women who do not have HIV and who have a low risk of getting HIV. Many new cases of HIV are the result of heterosexual activity. Condom use is currently the only effective way of preventing the spread of HIV and other sexually transmitted diseases (STDs). However, women, who have a greater risk of getting HIV, are often unable to convince their partner to use a condom. Therefore, it is important to develop methods that prevent the spread of HIV and that are controlled by the woman, such as medicines used in the vagina. BufferGel is known to kill the organisms that cause STDs, including HIV. BufferGel may do this without causing genital irritation and sores as other medicines do. More studies are needed to see if this is true.
To assess the acceptability of and participation in a group counseling intervention, including an assessment of willingness to disclose serostatus to a regular sexual partner and the willingness of that partner to participate. To evaluate the profile of adverse experiences (social, psychological, and physical harms) of individuals resulting from participation in counseling and testing and attempts to initiate condom use within a stable HIV serodiscordant partnership. To assess the potential for the intervention to result in increased condom use among stable sexual partners. There is a significant risk of HIV transmission to HIV-uninfected partners in HIV-discordant couples. While condom use has been a major component of most AIDS prevention programs since the mid-1980s, there has been little emphasis on promoting condom use within stable partnerships. The most effective way to promote condom use among discordant couples remains largely unknown.
The purpose of this study is to see if it is safe and acceptable for homosexual male couples, where both partners have the same HIV status, to use Advantage 24 during anal intercourse. Advantage 24 is a spermicide (a chemical that kills sperm). Much research and development is being done with chemicals that can be controlled by the receptive partner to prevent the spread of HIV and other sexually transmitted diseases (STDs). Advantage 24 currently is used in the vagina as a form of birth control. The safety of Advantage 24 is particularly important for HIV-positive men because they have a greater chance of serious reaction to Advantage 24 due to other HIV-related conditions.
The purpose of this study is to see how HIV reacts in the immune systems of patients who have recently been infected with HIV. This study also examines HIV's resistance to anti-HIV drugs in newly infected patients. Certain populations are good candidates for participation in HIV vaccine trials. These groups include men who have sex with men, IV drug users, and women at risk of getting HIV through heterosexual contact. Learning how HIV behaves in these populations once they become infected can help with the planning of future HIV vaccine studies.
The purpose of this study is to see if a behavioral intervention, a special kind of counseling, can reduce the risk of HIV infection in men who have sex with men. The behavioral intervention will be compared to the standard risk reduction counseling that is given before and after getting an HIV test. In standard pre- and post-test counseling, everyone is told the same things about how to prevent HIV. The behavioral intervention used in this study is designed to help each individual prevent HIV according to his specific problems and needs.
Some people who have taken azithromycin to prevent MAC (Mycobacterium avium Complex, a bacterial infection common in HIV-infected persons) have been found to carry antibiotic-resistant bacteria (germs that grow despite the presence of drugs used to kill them). The purpose of this study is to see if people who take azithromycin carry more antibiotic-resistant bacteria than people who have chosen to delay MAC preventive therapy. When bacteria like Streptococcus (a type of bacteria that causes pneumonia and meningitis) are frequently exposed to antibiotics, the bacteria can become resistant to the drugs. MAC preventive therapy uses antibiotics, but this can make it difficult to treat other infections caused by bacteria that have become resistant in HIV-infected persons. If MAC preventive therapy is delayed, Streptococcus in the body may be less likely to develop resistance. Therefore, if the patient does get a Streptococcus infection, it will be easier to treat because it is not resistant to the antibiotics.
This study is designed to test the clinical and laboratory observations that suggest IVIG given before and after kidney transplant to patients who are sensitized (highly sensitive) to certain transplant antigens could result in reduced sensitization and reduced rates of kidney rejection. Some ESRD patients are highly sensitive to certain transplant antigens (foreign substances that activate the immune system) and must wait for a long time before a well-matched kidney becomes available. Transplant rejection is more likely among highly sensitized patients than in patients who are not highly sensitized. There is no proven method to improve a highly-sensitized patient's chances of receiving and keeping a transplanted kidney.
The purpose of this study is to see how well antibiotics work in reducing chronic fatigue symptoms, such as tiredness, in patients that were treated for Lyme Disease. Fatigue is a common symptom of Lyme Disease. When fatigue does not improve after treatment, patients are considered to have Post Lyme Syndrome (PLS). The chronic fatigue seen in these patients appears to be related to the initial infection which causes Lyme Disease. It is believed, but not proven, that treatment with antibiotics may be effective in relieving chronic fatigue in PLS patients.
