Some patients taking anti-HIV drugs as part of highly active antiretroviral therapy (HAART) do not show any HIV in the blood; however, some HIV will remain hidden in the body and, if the drugs are stopped, will return to the blood. The purpose of this study is to determine if short periods of stopping HAART increase the activity of CD8 and CD4 cells (cells of the immune system that fight infection), if repeated stopping of these drugs for longer periods of time and restarting them will increase effectiveness of HAART, and if the increased immune system activity as a result of stopping treatment leads to lower levels of HIV over time.
This randomized clinical trial will determine the efficacy of physicians providing weight control advice to their overweight and obese patients in primary care practice.
The purpose of this study is to find out whether certain anti-HIV drugs (efavirenz [EFV] and nelfinavir [NFV]) affect the amount of certain fat-lowering drugs (atorvastatin, pravastatin, and simvastatin) in the blood. Protease inhibitors (PIs), a type of anti-HIV drug, are known to cause increased lipids (fats) in the blood of HIV-infected patients. EFV also is known to increase blood fats. HIV-infected patients who take PIs and/or EFV may need to take fat-lowering drugs to correct this problem. So it is important to look at possible drug interactions when these drugs are taken together. This study will see if taking EFV or NFV, a protease inhibitor, affects the blood level of simvastatin, atorvastatin, or pravastatin (all fat-lowering drugs). To obtain results more quickly, the study population will be healthy HIV-negative volunteers.
The purpose of this study is to find out if HIV-infected pregnant women who take protease inhibitors (PIs) are more likely to have blood sugar problems than those who do not take PIs. HIV-infected people generally are treated with a combination of different types of anti-HIV drugs, 1 of which is usually a PI. The same holds true for pregnant women, but not much is known about the use of these drugs in pregnancy. Blood sugar and liver problems caused by anti-HIV drugs in nonpregnant patients are well known but their effects in pregnancy are not. Also, certain physical changes brought about by pregnancy may affect the way drugs are handled in the body. There remains a need for further study into the use of anti-HIV drugs during pregnancy and their effect on the safety of the mother and baby.
The purpose of this study is to see whether acupressure (acupuncture using pressure applied by the hands instead of needles) can help nausea and vomiting in persons with HIV/AIDS.
This Phase I clinical trial is the first step in testing gene therapy. This study is called a "Safety/Toxicity" study by the Food and Drug Administration, and primarily aims to determine whether the experimental protocol is safe for humans. It will determine whether the study procedure causes side effects in humans, and may also give us a preliminary sense of whether this will be effective in combating Alzheimer's disease in humans.
To establish a collaborative group of clinical trial centers, with standardized equipment and protocols, able to conduct both drug and gene therapy trials in DMD. To evaluate the therapeutic effect of glutamine and creatine monohydrate on muscle strength in children with DMD. To validate the use of QMT (quantitative muscle strength testing) and gait analysis in children with DMD as reliable tools to quantify muscle strength, monitor disease progression and assess therapeutic response.
Patients on hemodialysis tend to have chronic elevations in the level of phosphorus in the blood and a secondary increase in the iPTH level. This chronic elevation in iPTH can have adverse consequences, thus a variety of phosphate binders are given in an attempt to decrease the absorption of phosphorus present in the normal diet. Some preliminary studies have indicated that the iPTH level may change based on the amount of phosphorus present in a meal prior to any significant absorption of phosphorus. If this is true in hemodialysis patients, then the timing of the administration of phosphate binders in relation to the ingestion of meals needs to be considered
The overall objective of this proposal is to examine the contribution of changes in total body fat, enhancement in insulin-mediated vasodilatation and enhancement in endothelium-derived nitric oxide production to the improvements in metabolic insulin action. In addition, the study will track whether these improvements are related to changes in blood pressure.
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of vaccine therapy in treating patients who have high-risk stage III or completely resected metastatic melanoma.
