An Open Trial Combining Zidovudine, Interferon-alfa, and Recombinant CD4-IgG With Transplantation...

HIV Infections

To restore immunologic function and virus-free state in HIV-infected patients. Based on previous studies showing temporary improvement in immune function in HIV-infected patients using peripheral lymphocyte transfers and bone marrow transplantation, and based on studies documenting the antiretroviral effects of zidovudine (AZT) and interferon-alfa (IFN-A) as well as the preliminary test tube and patient studies suggesting anti-HIV effects of recombinant CD4-IgG, we propose to treat HIV-infected patients using combination antiretroviral therapy with transplantation of bone marrow and peripheral lymphocytes from previously immunized donors in an attempt to restore immunologic function and a virus-free state.

An Assessment of the In Vivo Biological Effects of Diethyldithiocarbamate (DTC) in HIV-Infected...

HIV Infections

To determine, in HIV-infected patients, the magnitude and duration of the biological effects of ditiocarb sodium (sodium diethyldithiocarbamate; DTC) that may be relevant to treatment of HIV infection. DTC has been studied in previous clinical trials in HIV-infected patients with the suggestion of delay in disease progression to AIDS and improvement in CD4 counts while on the drug.

A Phase I Study to Evaluate the Safety and Toxicity of the Combination of Zidovudine and 2',3'-Dideoxyinosine...

HIV Infections

To assess the safety and tolerance of the combination of zidovudine (AZT) and didanosine (ddI) in children with HIV infection. New approaches to using available agents may provide increased or improved treatment options for AIDS. Combination therapy is expected to play a major role in improving survival and quality of life for HIV-infected individuals. AZT and ddI are two agents that have been most extensively evaluated and for which the evidence for antiretroviral effectiveness is strongest.

A Clinical Trial of Alternating and Intermittent Regimens of 2',3'-Dideoxycytidine and 3'-Azido-3'-Deoxythymidine...

HIV Infections

To determine if alternating zidovudine (AZT) and zalcitabine (dideoxycytidine; ddC) (first one and then the other) or intermittent therapy (1 week of drug then 1 week off) will lessen the toxic effects of either drug alone, while still inhibiting HIV (the AIDS virus) in patients with AIDS or AIDS related complex. AZT extends the survival of some patients with AIDS, and both AZT and ddC are known to inhibit the growth of HIV. When AZT or ddC is given continuously over a prolonged period of time, toxic effects occur that are not found when the drugs are given for 4 - 6 weeks. It is hoped that by alternating the drugs or by giving one drug intermittently, the toxic effects can be decreased without lowering the therapeutic effectiveness of the drugs.

A Phase I Trial of Intranasal Peptide T: Safety, Toxicity, and Pharmacokinetics in Human Immunodeficiency...

HIV Infections

To study the safety and toxicity of intranasal peptide T (D-Ala-1-peptide-T-amide) in humans, and to find out how quickly and how much of a given dose enters the bloodstream and how quickly it leaves the bloodstream. To obtain information on the ability of intranasal peptide T to prevent, halt, and/or reverse the effects of AIDS on the central nervous system. Studies have shown that AIDS is caused by a retrovirus. This virus works by inactivating or destroying human CD4 cells (which are part of the human immune system). This in turn leads to the observed immunologic defects and related illnesses, including HIV encephalopathy (disease of the brain). One method of preventing AIDS is to prevent HIV from entering the cell. HIV binds to the receptor CD4 site. Peptide T also binds to this site, and thus by competing for that site, can block the binding of the virus to its receptor. Preliminary animal and human studies indicate that peptide T is safe at the doses selected for this trial. Thirty patients with AIDS or AIDS related complex (ARC) are entered into the study to receive an increasing schedule of three dosage levels of intranasal peptide T for 12 - 16 weeks followed by a 1-month off-drug follow-up period and a subsequent 1-month return to the drug. All patients receive an initial intravenous test dose of peptide T. The test dose is administered over 1 hour, followed by an observation period of 8 hours in the outpatient clinic.

Humoral and Cellular Immunity Against SARS-COV-2 Vaccine in HIV-infected Patients Immunosuppressed...

SARS-CoV-2 RNA VaccinesHIV Infection

Prospective, non-equality, cohort study, where investigators propose to analyze humoral and cellular immunity after two doses of SARS-CoV-2 RNA vaccines in HIV-infected participants severely immunosuppressed. A total of 92 HIV-infected subjects over 18 years old with ≤200 CD4/μl (experimental group; n=46) and ≥ 350 CD4/μl (as control group; n=46) who have completed two doses vaccination against SARS-CoV-2 will be included in the study. Primary Objectives: To analyze the percentage of participants with SARS-CoV-2-specific IgG after 1, 6, and 12 months after vaccination in subjects with ≤200 vs ≥350 CD4/μL by electrochemiluminescence immunoassay (Elecsys® Anti-SARS-CoV-2. Roche Diagnostics). To analyze the percentage of subjects with specific T and memory B lymphocyte response against SARS-CoV-2 after 1, 6, and 12 months after vaccination with <200 vs ≥350 CD4/μL. Multiparametric flow cytometry in peripheral blood mononuclear cells (PBMCs) will be performed to detect the production of cytokines (IL-2, TNF-α and IFN-γ), cytolytic (perforin and granzyme B) and degranulation (CD107a) molecules from T cells, as well as to identify memory B cells specific to SARS-CoV-2 IgG+. Secondary Objectives: To analyze in participants with <200 vs ≥350 CD4/μl after 1, 6, and 12 months after vaccination: Quantification of specific IgG titers against SARS-CoV-2 The association of the T response to SARS-CoV-2 with humoral response parameters. The association of the T response against SARS-CoV-2 with other parameters of immune activation, inflammation and immunosenescence. The phenotypes of maturation (CD45RA and CD27), activation (HLA-DR and CD38), senescence (CD57+CD28-) and markers of immune exhaustion (TIGIT, LAG-3, TIM-3 and PD-1) in CD4 and CD8 lymphocytes T will be determined by multiparametric flow cytometry.

Improving Care and Community Representation for Adolescents and Young Adults Living With HIV in...

HIV InfectionsAdolescent Behavior1 more

Context: HIV-positive young people aged 15 to 24 are a heterogeneous population in terms of gender, age, mode of transmission, sexual orientation and risk-taking. This most vulnerable age group is at greater risk of disruption of medical care and poor compliance, and has greater needs for psychosocial support and differentiated health services. It remains highly invisible in West African countries, both in the definition of care policies and in the allocation of resources and community representation. Objectives: The overall objective of the project is to contribute to the improvement of retention in care, health and well-being of adolescents and young adults living with HIV (AYAHIV) and to support their integration into the community space. SO1: Support the operationalisation of the transition of HIV-infected adolescents from paediatrics to adult medical services in a stakeholder inclusive, participatory and responsive approach SO2: Contribute to the empowerment and autonomy of adolescents and young adults living with HIV in the project environment SO3: Contribute to the generation and dissemination of evidence-based information and recommendations on the situation and needs of adolescents and young adults, including key populations, living with HIV Target: Approximately 67 caregivers∙e∙s ≥ 25 years old, of which 64%F, 30 peer-referent associations of 20-24 years old (ratio F/H= 1:1), 700 AYAHIV ≥ 15 years old, of which 47%F, in paediatrics and 500-600 AYAHIV aged 15-24 years old in adult medicine, of which 41%F, and including AYAHIV associations Summary of activities: Based on the capitalisation and pooling of experiences of partner teams, the project proposes to support the implementation of transition in a pragmatic approach, adapted to the needs of adolescents and inclusive of carers, adolescents and community peers. More globally, it contributes to improving the health, empowerment and autonomy of HIV-positive youth, including key populations, in particular through support to training, structuring and community representation of youth associations, documentation of the conditions of entry into care and their specific needs, including digital health, production and availability of evidence and recommendations in this West African context and advocacy building. A multidisciplinary and participatory research-action project, carried out by the IRD in Senegal and financed by Sidaction, accompanies the three specific objectives of the project.

Intermittent ART in Primary HIV Infection

HIV

Interventions during primary HIV infection (PHI) can modify the immune control and the clinical evolution during the chronic phase. Although several studies suggest the benefit of antiretroviral treatment (ART) during PHI, indication of ART is still not universally recommended. The investigators randomized patients with PHI, with a favourable immunological profile and well controlled on ART, to undergone structured treatment interruptions alone or with low doses of IL-2, stopping ART thereafter. The endpoints were immune control of HIV replication and time to resume ART. Immunological profile, specific CD4 and CD8 responses and clinical data were analysed for both groups up to 48 weeks, and during a long follow-up, up to nine years since final ART stop.

Evaluating Drug Interactions Between Doravirine With Estradiol and Spironolactone in Healthy Transgender...

Transgender HealthGender Dysphoria2 more

Transgender women living with Human Immunodeficiency Virus (HIV) may prioritize gender-affirming hormonal therapy over antiretroviral drug therapy. Hormonal therapy typically consists of oral estradiol and spironolactone, which induce drug-metabolizing enzymes after prolonged administration. This study evaluates the bi-directional potential drug interaction between the antiretroviral drug, doravirine, when co-administered with estradiol and spironolactone.
