Study of Lyme disease during anti-CD20 treatment in France
Part of Infections clinical trials.
This study looks at people who got a serious form of Lyme disease while being treated with a type of biologic drug called an anti-CD20 (such as rituximab). The goal is to learn more about these cases and improve care. You may join if you had Lyme disease confirmed by a DNA test within two years of taking this medicine.

This trial is testing a new blood test to help diagnose Lyme disease (borrelia infection) in children. If you are at the emergency room with symptoms that might be Lyme disease and you have a healthy immune system, you might be able to join.
This study looks at how the immune system reacts to the bacteria that cause Lyme disease in people with a skin condition called ACA. It may help doctors understand the disease better and guide future treatments.
This study looks at people who have had Lyme disease more than once after traveling abroad. It aims to understand the patterns of the infection and why it comes back.
This study looks for certain antibodies in people with Lyme disease to understand how the body responds to the infection. It may help improve diagnosis or treatment for Lyme disease.
This study looks at the health of people who have had Lyme disease, including those with ongoing symptoms after treatment, and those who have recovered or never had it. It aims to understand the disease and find better ways to manage it.
This study evaluates and treats people who currently have active Lyme disease, as defined by CDC criteria. It aims to provide expert care and follow-up while studying the disease.
