Filter by:To investigate the role of chronic infection as a risk factor for vascular disease in a study of Native Americans. The primary focus is on the two most common agents Chlamydia pneumoniae and cytomegalovirus with a secondary emphasis on Helicobacter pylori.
To examine markers of underlying chronic inflammation and infection as potential risk factors for future myocardial infarction (MI), stroke (CVA), and venous thromboembolism (VTE) in plasma samples collected at baseline from healthy participants in the Physicians' Health Study (PHS).
To examine mechanisms of individual differences in the progression of HIV infection in hemophiliacs.
To conduct a multicenter epidemiologic study of the human retroviruses HIV-1, HIV-2, HTLV-I, and HTLV-II in volunteer blood donors from areas of the United States that were reportedly at high and medium or low risk for HIV. Also, to determine the prevalence of retrovirus seropositivity in first time blood donors; and the rate of retrovirus seroconversion in repeat blood donors as a measure of incidence of infection; to ascertain risk factors for antibody-positive donors; to characterize the blood donor population by geographic location, age, sex, race/ethnicity, and donation history to permit analysis on prevalence, incidence, and risk factors; to identify recipients of retrovirus-positive blood units and conduct clinical and laboratory follow-up of these recipients; and to establish a blood specimen repository for long-term storage of specimens from study donors and recipients for future testing.
To determine the prevalence and natural history of pulmonary and cardiac complications associated with HIV infection in utero, in infancy, and during early childhood.
To evaluate the types, incidence, course, and outcome of pulmonary disorders in newly diagnosed cases of Acquired Immune Deficiency Syndrome (AIDS), newly diagnosed cases of AIDS-related complex (ARC) and newly diagnosed asymptomatic human immunodeficiency virus (HIV) infection.
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.
OBJECTIVES: I. Evaluate the development of oral manifestations of human immunodeficiency virus infection in relationship to the onset of immunologic alterations and systemic symptoms in different risk groups: gay/bisexual men, male intravenous drug users, and female intravenous drug users. II. Evaluate the immune and inflammatory response to periodontal and other microbial pathogens. III. Evaluate the bacterial species infecting the oral cavity in patients in these risk groups.
OBJECTIVES: I. Evaluate the safety, tolerance, and potential efficacy of 3 doses of human anti-cytomegalovirus (CMV) monoclonal antibody SDZ MSL-109 (MOAB MSL-109) in the treatment of newborns with congenital CMV infection and no central nervous system disease. II. Determine the relationship between plasma concentrations of MOAB MSL-109 and therapeutic outcome. III. Determine whether MOAB MSL-109 influences the antibody response and clearance of virus from the urine.
OBJECTIVES: I. Evaluate the efficacy of ganciclovir (12 mg/kg per day) versus no treatment in neonates with symptomatic congenital cytomegalovirus infection with central nervous system disease.
