The purpose of this study is to compare the safety and effectiveness of an anti-HIV drug combination with and without hydroxyurea in patients with early HIV infection. Certain combinations of anti-HIV drugs have been effective in lowering levels of HIV in the blood and keeping them down. However, these treatments are not effective in some patients. This study will see if using a combination containing more drugs will help in patients with early HIV infection.
The purpose of this study is to find out if anti-HIV drugs, taken by patients who are newly infected with HIV, can make the level of HIV in the body too low to detect. Studying patients who recently have been infected with HIV may help researchers understand how HIV infection works and how anti-HIV drugs may help these patients. Approved anti-HIV drugs can reduce the amount of HIV, but more research needs to be done in newly infected patients. This study will look at recently HIV-infected patients to study the progression of HIV disease and to see whether anti-HIV drugs can reduce the level of HIV.
The purpose of this study is to see if the amount of stem cells (cells that can develop into many kinds of cells) in the blood before anti-HIV drugs are taken can predict if the immune system will become stronger after anti-HIV drugs are given and if anti-HIV drugs can restore stem cells. HIV infection has been shown to cause stem cells not to function well. Granulocyte colony-stimulating factor (G-CSF), which causes stem cells to go from the bone marrow (tissues in the bones where blood cells are formed) into the bloodstream, could possibly help boost immunity after anti-HIV treatment. This study examines the effects of G-CSF in helping the immune system become stronger after beginning anti-HIV treatment.
The purpose of this study is to follow responses to treatment with vaccinia immune globulin (VIG) for safety and clinical benefit [during HIV vaccine research]. VIG is purified from human blood and used to treat serious infections of the vaccinia (smallpox vaccine) virus or similar viruses. It is the only treatment available for those viruses. The only available supply of VIG has developed a discoloration over time and therefore is considered an investigational new drug by the FDA. This study will allow it to be used for intramuscular injection in a controlled setting for people who may need it [during HIV vaccine research].
The purpose of this study is to find out whether or not the addition of hydroxyurea to didanosine (ddI) and other anti-HIV medications will result in better control of HIV infection. The Food and Drug Administration (FDA) has approved ddI for treating HIV infections. Hydroxyurea is approved for treating some cancers and blood disorders. It works against HIV-1 when combined with ddI. Researchers need to look at how well patients may respond to hydroxyurea in combination with ddI and other anti-HIV drugs, and at any side effects.
This research will determine whether the Chinese herbal medicine (NPI-028) can make a significant contribution to the management of withdrawal and to follow-up treatment aimed at preventing or managing relapse in both women and men alcoholics. The herbal preparation has been used historically in the treatment of alcohol intoxication and is still prescribed in China and Southeast Asia. Efficacy has been documented but awaits the application of current research methods to establish efficacy, safety, and probable mechanisms of action. Preclinical studies have been carried out in alcohol-preferring rats and vervet monkeys to test efficacy in reducing voluntary alcohol intake, measure tolerance effects, and toxicological affects. The proposed human trial will develop a placebo, establish quality control, test methods of administration, and examine compliance issues. Following these preliminary steps, a placebo controlled trial will be conducted using 160 subjects (80 subjects per treatment condition with 40 of each gender). Alcohol use, craving, health status, psychological status, and at rates will be assessed using established measures that are current in addiction research.
The purpose of this study is to test another way to control the amount of HIV in the blood (viral load). Studies show that stopping all anti-HIV drugs for a time before switching to new anti-HIV drugs may improve the response in some individuals who are failing treatment. Other studies suggest a benefit if drug-resistance tests are used in selecting a new anti-HIV drug treatment. This study tests the effect of stopping anti-HIV drugs for a time before switching to anti-HIV drugs selected using drug-resistance test results.
Many patients with diabetes are under sub-optimal glycemic control. Central to the clinician's task in improving glycemic control is the management of hypoglycemic medication therapy, including the use of drugs such as insulin and sulfonylureas. Clinical trials have demonstrated that more intensive hypoglycemic medication therapy results in improved glycemic control. Yet quality measures for this critical process of care have not been developed and we know little about how physicians actually manage hypoglycemic medications.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining chemotherapy, radiation therapy, and surgery may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy, radiation therapy, and surgery in treating patients who have primary or recurrent sarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of temozolomide plus carboplatin in treating patients who have recurrent glioblastoma multiforme.
