An Expanded Access Study of Oral Liquid Efavirenz in the Treatment of Children With HIV Infection:...

HIV Infection

This study is being conducted to assess the safety and tolerability of an oral liquid solution of Sustiva for antiretroviral therapy-naive or therapy-experienced HIV-1 infected children between the ages of 3-16 who are failing or intolerant of their current antiretroviral regimen and who are unable to swallow Sustiva capsules.

Connect to Protect Partnerships for Youth Prevention Interventions: Phase II

HIV Infection

This is Phase II of a three stage project whose overall goals are to develop viable community-based HIV prevention interventions and to form and maintain the necessary community collaborations to support such Adolescent Trials Network (ATN) research activities. This phase will describe specific locations within high-risk areas where youth, ages 12-24, spend time. HIV risk behaviors, social networking patterns and HIV prevalence among youth at these venues will be assessed by administering anonymous computerized interviews to eligible and willing youth. This information will be shared with community partners during scheduled working group meetings.

Observing Patients With Early HIV Infection

HIV Infections

The purpose of this study is to monitor patients who have recently been infected with HIV in order to learn how their immune systems respond to HIV infection and to study how the virus multiplies in their bodies. Patients who have been infected with HIV recently are considered to have acute, or early, HIV infection. During this period, viral load (level of HIV in the body) rises sharply to a high level at first but then decreases significantly on its own. Doctors are not sure why this decrease in viral load happens and how the body is able to accomplish this. In this study, patients with acute HIV infection will be monitored so that doctors can study their immune systems to try to learn more about this rise and fall in viral load.

A Study of HIV Levels During Pregnancy and After Childbirth

HIV InfectionsPregnancy

The purpose of this study is to find out if HIV-infected pregnant women taking anti-HIV drugs have an increased amount of HIV in their blood (viral load) after having the baby. The purpose of A5153s, a substudy of A5150, is to characterize two anti-HIV drugs (nelfinavir [NFV] and lopinavir/ritonavir [LPV/r]) in HIV-infected women during pregnancy and after childbirth. Sometimes pregnant women have an increase in their HIV viral load after their baby is born. This study will try to find out how often this happens. It will also examine possible reasons why the increase in viral load occurs.

Screening HIV-Infected Patients for Vaccine Studies

HIV Infection

This screening study will evaluate potential study volunteers with HIV infection to see if they are suitable candidates for trials of experimental vaccines against HIV (therapeutic), and against other infections (preventive). Preventive vaccines against other infections. Preventive vaccines prevent a person from getting a disease. Preventive vaccines have been developed for many diseases, including, for example, whooping cough, measles, mumps, influenza, and hepatitis B. Some preventive vaccines may also prevent a disease from taking hold if given immediately after infection, such as vaccines for rabies, smallpox and hepatitis. Therapeutic vaccines against HIV. Therapeutic vaccines are intended to treat someone who has already been infected, with the goal of controlling the disease or preventing it from causing severe illness. As yet, there are no therapeutic vaccines for any diseases. Vaccines against other infections. Vaccines to prevent other infections besides HIV may need to be tested separately in people with HIV infection because the immune system works differently when HIV infection is present. HIV-infected patients 18 years of age or older may be eligible for this screening study. Women who are pregnant or breast feeding may not participate. Participants will be screened with the following: A health history, including questions about sexual activity and drug use; Physical examination, including blood and urine tests; HIV testing to confirm HIV infection; Pregnancy test for premenopausal women; PPD test for tuberculosis for those who have not been tested in the previous 6 months. Candidates who meet the requirements for investigational vaccine studies will be invited to participate in a study. Those who do not begin a study within 1 month of the screening tests may need to repeat some tests for continued consideration. In addition, some studies require repeated measures of CD4 counts and viral load over a period of a few months.

A Study to Collect Information About HIV-Positive Pregnant Women and Their Babies

HIV InfectionsPregnancy

The purpose of this study is to collect medical information about HIV-positive pregnant women and their babies who have been (or are being) seen at study sites. This information will be used to help design future research studies for these patients. The population of HIV-positive pregnant women and their babies who are seen at study sites has not been officially examined. In order to design future studies to research the best care for these patients, this study will examine important characteristics and the general number of women in these trials.

Identifying Emergency Room Patients Who Have Recently Been Infected With HIV

HIV Infections

The purpose of this study is to identify patients who have early HIV infection. Patients who have been infected with HIV recently may develop flu-like symptoms within 3 to 8 weeks. Those who go to the hospital emergency room for these symptoms and who may have been exposed to HIV recently will be given a questionnaire and the opportunity to be tested for HIV. Most people develop flu-like symptoms shortly after becoming infected with HIV, and many of these people go to a hospital emergency room for treatment. However, most doctors do not think of testing people with flu-like symptoms for HIV. This study will look at a plan to change this because it is very important to identify patients who have early HIV infection. Viral load (level of HIV in the blood) is very high during early HIV infection, and it is easy to spread HIV to others during this period. Patients who learn they are HIV-positive can stop risky behavior that might spread HIV to other people. Also, patients who find out early that they are HIV positive are able to begin anti-HIV treatment sooner, slowing the disease.
