Study gut microbiome in older adults with well-controlled HIV
This trial studies how the bacteria in your gut (“microbiome”) relate to frailty (weakness/low physical resilience) in people with HIV who are stably doing well on treatment. It may help researchers understand why some people become frail and how the gut may play a role.
MarseilleAges 55 years+ - NCT05536219Recruiting
Study how autoantibodies affect virus levels in severe lung infections
This study measures blood immune “autoantibodies” that may affect how much virus is in the body during severe respiratory infections. It may help doctors understand which patients are more likely to have higher virus levels and could guide future treatment choices.
Bron, RhoneAges Any age - NCT06199921RecruitingPhase 2
Atorvastatin plus TB treatment for new tuberculosis
This study tests whether adding the cholesterol drug atorvastatin to standard TB treatment helps people recover faster. It is for people with newly diagnosed, drug-sensitive tuberculosis who have not yet started treatment.

Immune monitoring for mold infections
This study tracks how your immune system responds to serious mold infections, like aspergillosis or mucormycosis. It may help doctors understand why some infections are hard to treat and could lead to better care.
ParisAges 18 years+ - NCT06291311Recruiting
Plasma treatment for cervical HPV infections
This study tests a new non-invasive plasma treatment for cervical infections caused by high- and low-risk HPV types. It may help clear the virus and prevent related health issues.
TübingenAges 18 years+ - NCT06282510RecruitingPhase 4
