Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study was designed as a cohort study comparing the immune response after vaccination of HIV-infected subjects with the hypothesis that subjects with ≤200 CD4/μL will have a worse response than those with CD4 count ≥ 350/μL.

Who may be able to join

  • HIV-infected subjects over 18 years old and ≤200 CD4/μl who have completed vaccination against SARS-CoV-2.
  • HIV-infected subjects with ≥350 CD4/μl who have completed vaccination against SARS-CoV-2 matched by age and sex as control group.
  • Sign the informed consent.

Who cannot join

  • Neoplastic or autoimmune disease known.
  • Treatment with steroids, immunomodulators, interferon, chemotherapy or any pathology that may impact immunological parameters after vaccination against SARS-CoV-2.
  • Active infections at the time of sampling.

About this study

Official title: Prospective Study to Evaluate the Persistence and Characteristics of Humoral and Cellular Immunity Against SARS-COV-2 After Vaccination in HIV-infected Patients Severely Immunosuppressed

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Antibodies

    Analyse the percentage of subjects with SARS-CoV-2-specific IgG after 1, 6, and 12 months after complete vaccination regimen in HIV-infected subjects and ≤200 vs ≥350 CD4/μL. And to analyse the percentage of subjects with specific T and memory B lymphocyte response against SARS-CoV-2

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of SARS-CoV-2 RNA Vaccines and HIV Infection, run by Hospitales Universitarios Virgen del Rocío at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Antibodies (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05633927, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2024; AzTrials last refreshed its copy on 8 Nov 2026.
