Filter by:Male circumcision (MC) reduces, by more than half, the risk of HIV-1 acquisition. WHO and UNAIDS recommend that "male circumcision should be recognized as an efficacious intervention for HIV prevention especially in countries and regions with heterosexual HIV epidemics and low male circumcision prevalence." As a result, programs have been introduced and scaled up for voluntary medical male circumcision. Kenya leads with the largest expansion of services. Early resumption of sexual intercourse after MC may have deleterious effects, including higher rates of post-operative surgical complications, and higher HIV acquisition among females in couples that resume sexual activity before certified wound healing. In the context of rapid scale-up of MC, adherence to post-operative clinic appointments allows clinicians to assess wound healing and to deliver risk reduction counseling. Abstinence from sexual intercourse before complete wound healing would reduce the rate of post-operative adverse events and minimize the risk of HIV transmission from HIV-infected men to their uninfected female partners. To the investigators knowledge, the effect of reminders delivered via text messaging to promote adherence to clinic visits and abstinence after MC has not been investigated. The investigators propose a randomized controlled trial in which men who will have undergone voluntary medical male circumcision at selected sites in Kisumu will be randomized to receive either the intervention (context-sensitive text messages after circumcision) or the control condition (usual care). This study seeks to determine (a) the effect of regular text messages sent to men after circumcision on attendance of the scheduled 7-day post-operative clinic visit versus usual care; (b) the proportion of men who resume sexual activity before 42 days post-procedure after receiving regular text messages versus usual care within the 42 days post-circumcision; and (c) to identify potential predictors of failure to attend the scheduled 7-day post-operative visit and early resumption of sexual intercourse.
The goal of this study is to develop a novel approach to hematopoietic stem cell transplantation for children with Severe Combined Immunodeficiency Disease (SCID) that eliminates the use of toxic chemotherapy conditioning and maximizes the likelihood of T and B cell immune reconstitution. Rather than classic chemotherapeutic agents, the investigators will utilize a targeted stem cell mobilizer, plerixafor, in combination with alemtuzumab, a monoclonal antibody. Correlative scientific questions will include: 1) efficacy and characteristics of host stem cell mobilization; and 2) alemtuzumab pharmacokinetics in very young children.
Purpose: To see how growing older changes the amount of HIV drugs in the blood of HIV-infected men and women. Many changes happen in the body as it ages that may affect the way drugs are carried in the blood, broken down or removed from the body. This study will look at the amount of drug in the blood and cells of the immune system for patients taking efavirenz, tenofovir and emtricitabine or atazanavir boosted with ritonavir, tenofovir and emtricitabine. Participants: The population will comprise of 56 (6 for intensive PK and 50 for sparse sampling) HIV-infected adults currently adhering to an antiretroviral regimen containing efavirenz with tenofovir and emtricitabine and the same number and distribution of HIV-infected adults currently adhering to an antiretroviral regimen containing atazanavir boosted with ritonavir with tenofovir and emtricitabine. Procedures (methods): This study will be completed at the University of North Carolina at Chapel Hill. There will be four groups of subjects: Efavirenz/tenofovir/emtricitabine Group A, Efavirenz/tenofovir/emtricitabine Group B, Atazanavir/ritonavir/tenofovir/emtricitabine Group A, and Atazanavir/ritonavir/tenofovir/emtricitabine Group B. The initial six subjects (Group A) for intensive PK analysis for each regimen will be recruited from the the UNC ID Clinic or the Moses Cone Health System Infectious Diseases Clinic, and will be comprised of non-frail subjects not currently receiving interacting drugs. If subjects provide informed consent, timed blood samples will be obtained to determine pharmacokinetic parameters around an observed dose of one of the two study regimens. A whole blood sample will also be collected and stored for potential drug metabolizing enzymes and transporters genotyping in the future. Group A subjects will complete a follow-up visit after their sampling visit. 50 subsequent subjects (Group B) for each regimen will be screened simultaneously, with no more than 10 subjects enrolled for each regimen in Group B prior to the completion and analysis of Group A. These subjects will also be recruited from either site. Group B subjects will have one or two sampling visits with 1 to 4 blood samples obtained at each visit, with a stored sample for future genotyping obtained on one of the visits. Samples will be collected just prior to a dose, at 2 hours, between 4 and 6 hrs, and between 10 and 14 hours after a medication dose. These visits may coincide with the subjects' regularly scheduled visit to the clinic, or be scheduled separately, depending on the preference and availability of the subject.
X-linked severe combined immunodeficiency (SCID-X1) is an inherited disorder that results in failure of development of the immune system in boys. This trial aims to treat SCID-X1 patients using gene therapy to replace the defective gene.
The original purpose of the study is to assess the long-term safety, tolerability, and practicability of the subcutaneous (SC) treatment with Immune Globulin Subcutaneous Solution (IGSC), 10% facilitated with recombinant human hyaluronidase (rHuPH20) in participants with Primary Immunodeficiency Diseases (PID) who have completed Baxter Clinical Study Protocol No. 160603. Following a discussion with the FDA, all participants still active in the study stopped treatment with rHuPH20 to assure safety of the participants participating in the study and went into a safety follow-up. During this safety follow-up period, participants underwent either intravenous (IV) or SC treatment with IGSC, 10%. The IV or SC administration route was at the discretion of the participant and the investigator.
Human Immunodeficiency Virus (HIV) infection is permanently established by integrating a deoxyribonucleic acid (DNA) copy into the human chromosome, a step also necessary to complete the Human Immunodeficiency Virus (HIV)replication cycle. Standard treatment of HIV infection suppresses Human Immunodeficiency Virus (HIV)replication and has not been able to eliminate Human Immunodeficiency Virus (HIV)from an infected person because of the integrated Human Immunodeficiency Virus (HIV). Raltegravir (RAL), the first approved antiretroviral (ARV) in a new class called integrase inhibitors, works by preventing integration of Human Immunodeficiency Virus (HIV). For participants with Human Immunodeficiency Virus (HIV)who have never taken antiretroviral medications, this research study will test whether Raltegravir (RAL), a recommended first-line ARV, can eliminate Human Immunodeficiency Virus (HIV)from key immune system cells.
Intervention to investigate the efficacy of a nutritional supplement among ARV-naïve, asymptomatic HIV positive patients with a CD4 count in the range 300-550 cells/ul.
This study will draw from proven interventions to refine and pilot test a cue card driven computer-assisted intervention, along with HIV/STI testing, that will be tailored to each participant's demographic characteristics, risk behaviors, and biological test results. The specific aims of the proposed study are: 1. To refine a cue card driven computer-assisted risk reduction intervention that will be tailored to each participant's demographic characteristics (e.g., gender, ethnicity), risk behaviors, and biological test results (HIV, hepatitis B and C, syphilis and herpes). 2. To pilot test the tailored intervention's effects on sexual risk behaviors (e.g., frequency of unprotected sex, condom use), drug use during sex and injection risk behaviors (e.g., direct syringe sharing, indirect sharing practices) using a two-group randomized design that compares the tailored intervention with a delayed treatment control condition. 3. To assess the feasibility and acceptability of the tailored intervention in a rural setting.
This study is a retrospective chart review of the use of subcutaneous IgG (SCIG) in infants less than two years old.
The aim of the study is to observe the tolerability and effectiveness of Kaletra in Human Immunodeficiency Virus/Hepatitis-B Virus and Human Immunodeficiency Virus/Hepatitis-C Virus co-infected patients.
