Filter by: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.
The use of protease inhibitors is increasing in HIV-infected children because this treatment has resulted in improved body weight, improved immune status and less hospitalizations. However, recent reports suggest that these drugs may also be associated with some negative side-effects, specifically a syndrome of diabetes and fat redistribution. Development of the fat redistribution/diabetes syndrome has recently been reported in HIV-infected children, as well as in adults. Diabetes is associated with complications such as increased heart disease, eye disease and loss of kidney function. Thus development of diabetes is a significant problem which could outweigh the benefits obtained by treating patients with protease inhibitors. One major cause of diabetes is lack of normal response to insulin (insulin resistance). Insulin resistance tends to be worse in family members where one or more parent has diabetes, and is also worse in certain ethnic groups. The first major purpose of our study is measure insulin resistance in HIV-infected children who do not take protease inhibitors, and compare our findings to those from patients who are treated with protease inhibitors. We will also follow patients newly treated with protease inhibitors for two years to evaluate changes in insulin sensitivity. These results will be correlated with each patient's family history of diabetes and with ethnicity, and should help us better predict which children are "at risk" for development of diabetes from protease inhibitor therapy. Children with HIV infection often have problems with gaining enough weight and with poor linear growth (height). One likely reason for this is the way their bodies use and store protein. The second purpose of our study is measure protein turnover and to correlate our findings with growth data. We also plan to study the effects of protease inhibitor therapy on protein turnover. We believe that these studies will provide knowledge to help clinicians formulate recommendations for nutritional and medical therapy.
The purpose of this study is to see if a type of anti-HIV therapy called HAART is effective in lowering levels of HIV and boosting the immune system in HIV-infected patients with tuberculosis (TB). HIV-infected patients with TB have higher levels of HIV and lower CD4 cell counts (cells in the body that fight infection) than HIV-infected patients without TB. HAART has been effective in reducing HIV levels and increasing CD4 cells in patients without TB. However, its effects in HIV-infected patients with TB are unknown.
The purpose of this study is to determine the number of newly formed CD4 cells in children who have taken anti-HIV drugs. The study will also evaluate the effectiveness of the new CD4 cells in producing an immune response to hepatitis A and tetanus toxoid vaccination. Study hypothesis: 1) Immunologic reconstitution of individuals who have less than 15% CD4 cells may or may not be associated with functional activity. 2) The functional immunologic responses to recall and newly experienced antigens may be different. 3) The functional responses to antigens delivered in vaccine format may be a function of CD4 level, viral load, or both.
OBJECTIVES: I. Evaluate the effect of aerobic exercise and progressive resistance plus megestrol acetate on lean body mass of patients with human immunodeficiency virus-related weight loss (HIV-wasting). II. Evaluate whether exercise acutely alters immune function. III. Evaluate whether long-term exercise improves immunocompetence. IV. Evaluate the accuracy of multifrequency bioelectrical impedance spectral analysis in measuring body composition. V. Assess the impact of these therapies on quality of life. VI. Evaluate the effect of these therapies on the balance of energy intake and energy expenditure.
The purpose of this study is to see if a certain combination of anti-HIV drugs is safe and effective in HIV-infected patients. The drug combination includes a tablet containing lamivudine and zidovudine (called Combivir) plus abacavir plus efavirenz.
The purpose of this study is to look at the safety and effectiveness of an experimental protease inhibitor (a type of anti-HIV drug) called BMS-232632. Doctors will compare an anti-HIV drug combination that includes BMS-232632 to a drug combination that includes ritonavir.
The purpose of this study is to see how safe a new protease inhibitor (PI) is and how well it fights HIV infection. A PI is a drug that stops HIV from using healthy cells to make more virus. This study will compare the new PI combination of ABT-378 plus ritonavir (RTV) with another PI, nelfinavir (NFV). Earlier studies suggest ABT-378/RTV will be just as good as and perhaps better than NFV at fighting HIV infection.
The purpose of this study is to see if ABT-378/ritonavir plus efavirenz is safe and effective in lowering the amount of HIV in the blood of patients who have been treated with more than 1 protease inhibitor (PI).
The purpose of this study is to compare the safety and effectiveness of 2 anti-HIV drug combinations in HIV-infected patients. Both combinations will include nevirapine (NVP), 2 nucleoside reverse transcriptase inhibitors (NRTIs), and at least 1 protease inhibitor (PI). One combination will include a new protease inhibitor, ABT-378, combined in a capsule with ritonavir (RTV).
