Filter by:The purpose of this research study is to test the safety of and the body's response to an experimental cytomegalovirus (CMV) vaccine (called gB/MF59 vaccine). Participants will include approximately 400 healthy females, ages 12-17, recruited from adolescent clinics at Cincinnati Children's Hospital Medical Center, Vanderbilt University Medical Center, Baylor College of Medicine, University of Texas School of Public Health, Houston, and the University of Texas Medical Branch at Galveston. Participants will receive 3 doses of vaccine or placebo (saltwater) on a 0, 1, and 6 month schedule. Study procedures will include blood and urine samples. Participants will complete a diary recording temperatures and any side effects experienced. Subjects will be involved in study related procedures for up to 31 months.
There is conflicting evidence regarding the influence of HIV infection on the success of malaria prevention in pregnancy and effect on pregnancy outcome. The purpose of the proposed study is to assess the impact of HIV infection on the effectiveness of malaria prevention during pregnancy. This will be carried out by comparing two intermittent preventive treatments (IPTs) with sulfadoxine/pyrimethamine (SP) plus 300 mg weekly chloroquine with two doses IPT plus a weekly chloroquine placebo. The emphasis will be on assessing the effect of chloroquine on HIV viral load and malaria morbidity and foetal outcome. The study will be a randomised double-blind placebo-controlled trial with two arms, involving pregnant women attending antenatal classes (ANCs) at health units, enrolled early in their second trimester at 3 health units of the Mbarara district and Kampala. All pregnant women presenting for antenatal care, irrespective of parity, who consent to participate will be enrolled. Women with severe systemic disease or symptoms of AIDS will be excluded from the study data analysis. Women will be screened for HIV status and their HIV viral loads will be measured at enrolment. Parasitaemia will be assessed at enrolment; at the beginning of the third trimester; and at delivery. Haemoglobin will be measured at the same time points. The main outcome variables to be assessed will be maternal peripheral parasitaemia; placental parasitaemia; maternal clinical malaria; congenital parasitaemia; and maternal and neonatal haemoglobin, birth weight and viral load at enrolment and before nevirapine administration to the HIV positive mothers at birth. Anthropological pre-studies to assess the quality of ANC services and healthcare seeking practices of pregnant women in the study area will be carried out. Focus group discussions (FGD) with pregnant women and mothers of neonates; in-depth interviews with relevant health workers; and illness narratives from pregnant women will be used to collect data. The anthropological study results will assist in appropriately planning for the trial to enhance compliance to the intervention. The data collection is planned to commence in August 2003 and is expected to end in October 2005. Twelve months will be spent on the write-up phase.
The purpose of this study is to determine if, among women who were treated for a prior chlamydial infection, home-based, self-collected vaginal swabs can increase rescreening for chlamydia in comparison with rescreening in the clinic. The study design is two randomized trials with enrollment at multiple family planning clinics and sexually transmitted disease (STD) clinics following a common protocol.
The purpose of this study is to determine whether pegylated interferon therapy is effective to treat acute hepatitis C infection in HIV-coinfected individuals.
The primary endpoint is coronary artery diameter, normalized for body surface area, 5 weeks after randomization. Secondary endpoints include duration of fever, CRP levels, and adverse events.
Identifying methods to slow disease progression in patients with HIV-1 infection remains a top priority in many regions of the world. In many countries, medications known to slow progression are not readily affordable or available. Many of the individuals living in these countries are also co-infected with a variety of other diseases such as tuberculosis, malaria and soil-transmitted helminths. There are data to suggest that infection with these agents may activate the immune system in HIV-1 co-infected individuals and may lead to more rapid HIV disease progression. This study will evaluate the potential impact of treating helminths in HIV-1 seropositive individuals. Markers of disease progression and immune activation will be assessed. We will also measure the amount of virus in genital secretions to determine if treatment of co-infection can reduce the infectiousness of HIV in these individuals.
This is a randomized multicentre trial of emtricitabine (FTC) versus tenofovir (TDF)/FTC in antiretroviral naive subjects with HIV/HBV co-infection over 48 weeks (Clinical Trial A). Plus, a 12 week viral kinetic substudy comparing a subgroup of patients on Clinical Trial A is being conducted. (Substudy A1)
In the United States (U.S.) there currently is no standard method of umbilical cord care, resulting in varying practices within and across institutions. These differences may result in an increase in morbidities for newborns such as the formation of umbilical granulomas and increases in acute care utilization. This study will determine which of two common methods of caring for newborn umbilical cords is superior - triple dye, followed by the application of rubbing alcohol, or triple dye alone.
Human Papilloma virus (HPV) are viruses that cause a common infection of the skin and genitals in men and women. Several types of HPV infection are transmitted by sexual activity and, in women, can infect the cervix (part of the uterus or womb). This infection often goes away by itself, but if it does not go away (this is called persistent infection), it can lead in women over a long period of time to cancer of the cervix. If a woman is not infected by HPV, it is very unlikely that she will get cervical cancer. This study will evaluate the efficacy of GSK Biologicals HPV 16/18 VLP/AS04 vaccine to prevent infection associated cervical pre-cancer and vaccine with HPV 16 or 18 and the vaccine safety, over 48 months, in young adolescents and women of 15/25 years of age at study start. Approximately 18.000 study subjects will either receive the HPV vaccine or a control vaccine (hepatitis A vaccine) administered intramuscularly according to a 0-1-6 month schedule.

This is an observer blind follow up study of the study HPV-001, which evaluated the ability of the HPV vaccine to prevent HPV infection. The current study invites all of the 1113 subjects in the HPV-001 study that received all three doses of vaccine/placebo to be enrolled and followed-up for several additional years to see if the HPV vaccine prevents HPV-16 and HPV-18 infections and to evaluate the safety of the vaccine. Subjects will remain in the same study group as in the primary study. No vaccine or placebo will be administered in this study.
