In Vitro Studies of Immunological and Stem Cell Function in Peripheral Blood Mononuclear Cells in...
Immunologic Deficiency SyndromeLeukemia2 morePeripheral blood mononuclear cells (PBMC) will be collected from patients who have leukemia or lymphoma or other medical conditions involving altered lymphohematopoietic stem cell or immunological function. These PBMC will be assessed for cellular markers by flow cytometry and will be studied for in vitro T helper, effector and suppressor cell functions, to determine whether cell mediated immunity is involved in the condition, or indicative of therapeutic efficacy or is predictive for outcome. Peripheral blood stem cells (PBSC) from untreated donors and from cytokine treated donors will be assessed for cellular markers and in vitro growth characteristics that might be useful for identifying normal stem cell populations.
Safety and Survival of Genetically Modified White Blood Cells in HIV-Infected Persons - A Study...
Acquired Immunodeficiency SyndromeHIV InfectionThis study will evaluate the safety of giving lymphocytes (white blood cells) containing a new gene to HIV-infected individuals and will determine how long the cells survive in the bloodstream. Although the genetically altered cells will not directly benefit participants, knowledge about the safety, side effects and survival of these gene-marked cells in HIV-infected patients may lead to new treatment strategies. Identical twin pairs 18 years of age and older-one infected with HIV, the other non-infected-may be eligible for this study. Candidates will be screened with a medical history, physical examination and blood tests. All participants will have a tetanus booster shot. Non-infected twins will undergo a procedure called apheresis to collect white blood cells. For this procedure, whole blood is collected through a needle in an arm vein, similar to donating blood. The blood is separated it into its components by centrifugation (spinning), the white cells are removed, and the rest of the blood is returned to the body, either through the same needle or through another needle in the other arm. The harvested white cells will be grown in culture for approximately 10 days to 2 weeks to increase their numbers up to 1000-fold. A gene called NeoR, which is derived from bacteria, will be inserted into the cells, and these gene-marked cells will be infused into the HIV-infected twin. HIV-infected twins will be admitted to the NIH Clinical Center for the first cell infusion. The gene-marked cells will be infused over a 60-minute period through a plastic tube (catheter) placed in an arm vein, or, if a suitable arm vein cannot be found, through a special catheter placed into a large vein in the neck or chest. Vital signs (temperature, pulse, blood pressure and breathing rate), blood oxygen concentration, and urine output will be monitored regularly for 24 hours. Blood samples will be collected before and after the infusion to monitor for gene-marked cells. Patients will be discharged the next day. They will return to NIH daily the first week (from Monday through Thursday) to monitor for CD4 cell counts, plasma viral burden, p24 antigen levels, HIV levels and the presence of the NeoR gene, and then weekly for the next 5 weeks for these tests and others to monitor blood and urine chemistry, blood counts and immune function markers. If the NeoR gene cannot be detected after the first cell infusion, the entire procedure (donor apheresis, gene marking and infusion of cells) will be repeated twice-about once every 6 weeks. If the first infusion was uncomplicated, the second and third infusions may be done on an outpatient basis, with monitoring for 6 hours rather than 24. Six weeks after the third infusion, tests will be scheduled monthly for 6 months and then yearly for long-term follow-up. In addition to the above procedures, patients with a baseline CD4 lymphocyte count less than 100 cells per cubic millimeter of blood will be asked to undergo apheresis periodically to obtain the most accurate results for determining how long the NeoR gene persists in the blood. The procedure will be done weekly for the first 6 weeks after each infusion of cells, then at week 8, and then every 4 weeks until the gene can no longer be detected in the lymphocytes. The schedule may change, but will not require more frequent apheresis.

Enhanced Prevention in Couples: Feasibility Study #2
Human Immunodeficiency Virus (HIV)Acquired Immune Deficiency Syndrome (AIDS)The purpose of this study is to gather information needed to develop a large prevention trial to decrease risk for Human immunodeficiency virus (HIV) transmission among HIV-discordant couples (where one person is HIV-positive and the other is HIV-negative) in Lesotho. The protocol team would like to explore new strategies for increasing the number of partners who receive an HIV test and whether this increase in testing also results in identifying HIV-discordant couples. These couples would be the focus of the future large prevention trial therefore it is critical that the protocol team explore effective strategies for identifying and recruiting these couples. Men and women (index participants) who are attending antenatal (ANC) and Tuberculosis (TB) clinics will be recruited for this study. If they agree to take part, a testing team will visit their household and offer all adults staying in the house the opportunity to receive an HIV test. Three hundred index participants will be enrolled into the study and have their homes visited by the testing team. The number of household members tested will depend on the number of people living in each household.

Community Based Screening for HIV Self Testing in FSW in 23 Priority Districts in Indonesia
Human Immunodeficiency Virus (HIV)Indonesia is not yet on course to end HIV and AIDS by 2030. Epidemic transmission of HIV infection among key affected populations (KAPs), specifically FSWs, crucially has contributed to not achieving the target. Although the number of HIV tests performed annually has grown steadily in recent years, reaching 3,077,653 in calendar year 2018, pregnant women is accounted for a fairly large proportion of an increased number of persons being tested (MoH, 2018). Regarding the FSWs, it has been a significant challenge to increase HIV testing uptake among this population. The challenge has been affected by Indonesia's national policy to close brothels. As consequence, many FSWs have become hidden and hard to reach. The implementation national policy also impacts on the way of commercial sex transactions in which it becomes underground, especially many FSWs utilize the new popularity of digital platforms to sell sexual services. It needs more effective case finding strategies to be implemented to reach them accordingly. If it is considered from the FSWs side, there are some barriers to access HIV test services according to several reports. They consist of lack of money, time, stigma, discrimination, low-risk perception, fear, lack of accessibility, reluctance of health service providers to offer HIV testing and limited human resources. Oral fluid HIVST using is an alternative to traditional HIV testing services in the facility or other healthcare provider testing (UNAIDS, 2016). For this study, OraQuick is used as an alternative strategy for HIV testing among FSWs. The primary objectives of this study are to assess whether proportion of FSW, who know their HIV status, increases or not; whether introduction of Oral fluid test increases the number of HIV testing at health facilities or not; and whether "assisted" or "unassisted" community HIV screening have a result to an increasing proportion of HIV testing at health facilities or not. Furthermore, CBS study aims to assess whether "assisted" and "unassisted" community HIV screening results to an increasing number of HIV positive case finding or not; and whether community HIV screening increases proportion of initiation of antiretroviral therapy (ART) or not. The secondary objectives of this study, meanwhile, are to measure acceptability of community-based self-screening in participation and to measure satisfaction of FSWs, who has participated, towards the delivery of community-based self-screening. Regarding the inclusion criteria of this study, participant must be women 18 years old or older at enrollment; has a transactional sex (vaginal, oral and/or anal) at least once in the past month; does not uptake HIV test in the last 6 months; and acknowledges her HIV status 'negative' or 'unknown'. There are several exclusion criteria, which are FSW does not able to fulfill one of inclusion criteria that has been explained above; FSW does not has desire to participate due to several reasons; and she is currently participating in another HIV prevention study. Outcome variables of this study are to compare the characteristic FSWs who receive self-testing and blood testing; who receive assisted and unassisted self-testing. Moreover, it compares the proportion of taking confirmatory test out of those who receive the test in the assisted and unassisted self-testing; proportion of FSWs who receive HIV test out of those who got offered for the test (including self-testing) in the intervention group with proportion of FSWs who receive HIV test in the control group; the proportion of FSWs taking confirmatory test (including self-testing) out of those receive the test in intervention groups and control group. It compares, furthermore, the proportion of HIV positive in the assisted, unassisted (intervention) and HIV positive in the control group. This study also compares ART initiation in the assisted, unassisted (intervention) and the control group. Additionally, it compares stigma scores and FSWs who went to a health facility for HIV testing between assisted, unassisted group and compares the HIV and STI risk behaviors between assisted and unassisted group. It calculates, lastly, the cascade of HIV testing and treatment.
