What this research studies

If my child has Lyme meningitis, this project will follow children treated with either IV ceftriaxone or oral doxycycline at 20 centers in U.S. regions where Lyme disease is common. Doctors will pick the treatment as they normally would, and with consent the team will track short-term recovery, complications from IV lines or medications, and long-term quality of life. The study will also gather views from patients, parents, and clinicians about treatment preferences to help shared decision-making. Results aim to clarify which approach balances effectiveness, safety, and burden for families.

Who could benefit from this research

Good fit: Children diagnosed with Lyme meningitis who receive care at one of the participating centers and whose families consent to follow-up are ideal candidates.

Not a fit: Adults, patients without Lyme meningitis, or children treated outside participating centers are unlikely to be included or benefit directly from this project.

Why it matters

Potential benefit: Could identify a safer, equally effective oral option that avoids IV catheter complications and lowers burdens and costs for children with Lyme meningitis.

How similar studies have performed: European trials in adults and small pediatric observational studies suggest doxycycline can be effective, but strong comparative pediatric data are limited.
