Impact of Viral Infections on Blood Cell Development

Virus-induced Immunosuppression Via Infection of Hematopoietic Progenitors

Observational Assistance Publique - Hôpitaux de Paris · NCT06458504

This study is trying to see how HIV and COVID-19 affect the development of blood cells in both healthy people and those with HIV by looking at their bone marrow.

What this trial studies

This observational study aims to investigate how HIV-1 and SARS-CoV-2 affect hematopoietic stem and progenitor cells (HSPC) and their role in blood cell development. It will evaluate the susceptibility of HSPC to these viruses and assess the potential modulation of the bone marrow environment by infected cells. The study will involve both HIV-positive patients and healthy subjects undergoing bone marrow biopsies or myelograms at Ambroise Paré Hospital. The findings could provide insights into the mechanisms of virus-induced immunosuppression and its effects on hematopoiesis.

Who should consider this trial

Good fit: Ideal candidates include HIV-positive patients and healthy individuals undergoing bone marrow evaluations at Ambroise Paré Hospital.

Not a fit: Patients without any hematological concerns or those not managed at Ambroise Paré Hospital may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of immunosuppression in patients with HIV and COVID-19.

How similar studies have performed: While studies have explored the effects of HIV on hematopoiesis, the specific investigation of SARS-CoV-2's impact on HSPC is relatively novel.
