Filter by:The purpose of this study is to examine the effect of GB virus C (GBV-C) on the natural history of chronic hepatitis C virus (HCV) infection in subjects co-infected with HIV and HCV. The other aspect of the study is to assess the effect of GBV-C on the severity of liver disease due to chronic hepatitis C in subjects co-infected with HIV and HCV. This will be done by determining the point prevalence of co-infection retrospectively then following that cohort prospectively. In addition, further individuals will be recruited in a prospective manner.
Ritonavir boosted protease inhibitor based therapy will have equivalent antiviral efficacy over 48 weeks compared to NNRTI based therapy in patients who are antiretroviral therapy naïve and initiate therapy with CD4 counts ≤ 200/mm3.
The purpose of this study is to determine the pharmacokinetics, efficacy and safety of Immune Globulin Intravenous (Human), 10% TVR (Triple Virally Reduced) Solution in subjects with primary immunodeficiency (PID) manifesting as hypo- or agammaglobulinemia. Subjects are treated every 21 days and receive a total of 12 infusions: for the first 3 infusions subjects receive GAMMAGARD S/D to ensure a steady-state and to acquire data with a licensed product; for the remaining 9 infusions subjects receive IGIV, 10% TVR Solution.
To show the feasibility of liver transplantation in HCV-HIV coinfected patients. To study the two-year survival after transplantation, the interaction between HCV and HIV after transplantation, the influence of HIV on HCV recurrence after transplantation, the interaction between immunosuppressive and antiretroviral drugs in particular anti-proteases, immunological follow-up and quality of life of these patients
The purpose of this study is to assess the safety and efficacy of Immune Globulin Intravenous (Human), 10% (IGIV 10%) in subjects with primary immunodeficiency disorders.
Treatment for severe combined immunodeficiency (SCID) is a medical emergency. A stem cell transplant (immature blood cells that can make other blood cells) from a (MSD) matched sibling donor (brother or sister who is a "match" for your child's immune (HLA) type), usually results in complete correction of immune function. However, most patients lack a matched sibling donor, requiring the use of an alternate donor source. Transplantation of cells from haploidentical family donors (typically parents) has resulted in immune system correction in the majority of SCID individuals. However, only 65-80% of patients survive greater than one year after this procedure. Failure results from life-threatening infections, graft versus host disease (GvHD) or post-transplant treatment-related effects. Also, for patients that survive beyond one year, B-cell (type of blood cell that fights infection) and natural killer cell function (cell that attacks infections and cancer cells) frequently fail to work, resulting in the need for long-term treatment with intravenous gamma-globulin (IVIg). In this study, in an effort to restore the overall cell function in patients with SCID, researchers will use a highly purified CD133+ hematopoietic cell graft (stem cell transplant without many mature donor white cells, called T-cells) obtained via use of the Miltenyi CliniMACS device, a device not FDA approved.
To determine whether a regimen of single dose nevirapine combined with either 4 or 7 days of Combivir®, compared to a regimen of single dose nevirapine, for the prevention of mother to child transmission can reduce the rate of development of drug resistant mutations of HIV-1, in HIV-1 infected pregnant women, who have not received antiretroviral therapy previously.
To determine the response to treatment with NVP, ZDV and 3TC in HIV positive women, who previously received NVP for the prevention of mother to child transmission.
This study will evaluate patients with abnormal immune function that results in recurrent or unusual infections or chronic inflammation. This may include inherited conditions, such as X-linked severe combined immunodeficiency (XSCID), chronic granulomatous disease (CGD), and leukocyte adhesion deficiency (LAD), or conditions resulting from outside factors, such as graft-versus-host disease (GVHD). The information from this study will be used to establish the pattern and pace of change of the disease and to help develop new treatments. The period of observation and study following enrollment in this study may be for up to one year. In addition these studies may provide the medical information needed to determine eligibility for enrollment in other clinical study protocols and more prolonged follow up. Patients of any age with abnormal immune function who have recurrent or unusual infections, whose blood tests show evidence of immune dysfunction, or who have GVHD, XSCID, CGD or LAD may be eligible for this study. Patients' parents, siblings, grandparents, children, aunts, uncles and first cousins of any age also may be included. Healthy normal volunteers between 18 and 85 years of age are recruited as controls. Normal volunteers undergo a physical examination and provide blood, saliva, and urine samples for immune function studies. Patients' family members provide a medical history, have a physical examination, and give blood and urine samples, and possibly a saliva sample. The samples are used for genetic and routine laboratory studies. Investigators may request tissue samples, such as biopsy specimens, previously removed for medical reasons to be sent to NIH for study. Patients undergo the following tests and procedures: 1. Medical history and physical examination. 2. Blood and urine tests, including analysis for genes involved in immune disorders. 3. Buccal smear (in some patients) for genetic studies. This involves scraping the lining of the mouth near the cheek. 4. Specialized tests to evaluate specific conditions in patients who have an immune disorder that might affect lung function, gum infections or eye problems. These may include chest x-ray, CT scan, breathing function test, dental, eye, and hearing examinations. 5. Follow-up visits of patients with immune problems may occur at 6 months and at one year after the first visit (or more frequently if medically required) to include: - Medical history update - Physical examination - Follow-up on abnormal test results and medical treatments initiated at NIH - Collection of blood, saliva, urine, or wound drainage samples for repeat immune function studies - Tissue study of specimens removed for medical reasons at other institutions besides NIH
The purpose of this study is to evaluate the long-term safety and tolerability of etravirine, administered as part of an individually optimized antiretroviral therapy (ART), in human immunodeficiency virus Type 1 (HIV-1) infected participants.
