Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this pilot study is to assess the feasibility of longitudinal neurodevelopmental evaluation of fetuses and infants exposed to Lyme disease in utero. Participants with Lyme disease or Post-Treatment Lyme Disease Syndrome (PTLDS) will be recruited during pregnancy. Pregnancies will be monitored and infant development will be assessed from birth until age 18 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Childhood neurodevelopmental outcomes following antenatal Lyme disease exposure are not yet known. This pilot study will lay the groundwork for a larger study to determine the effect of in utero exposure to Lyme disease on pregnancy and early childhood neurodevelopmental outcomes. Understanding the effects on the developing brain is essential in order to inform timely prenatal and postnatal treatments to protect the fetus exposed to Lyme disease during pregnancy. Once childhood neurodevelopmental outcomes are known, appropriate follow-up and treatment guidelines can be developed to help better support children's developmental needs.

The primary aim of this study is to assess the feasibility of longitudinal follow-up of fetuses and infants exposed to Lyme disease in utero.Lyme disease in pregnancy and the impact on the fetus/child following in utero exposure has been identified as a priority research area; this pilot study is the essential step to plan a large study that will fill this knowledge gap and make a substantial contribution to the field.

The investigators will perform a prospective pilot longitudinal cohort study of B. burgdorferi-infected parents and their in-utero-exposed fetuses/infants. Patients included in this study will have a clinical diagnosis of Lyme disease during gestation or have been diagnosed with Lyme disease and/or PTLDS within 3 years preceding pregnancy.

Pregnant participants will receive a fetal MRI and ultrasound during the second or third trimesters of gestation. The investigators will conduct optional qualitative interviews with interested participants during their 3rd trimester to gather additional data on their experiences with Lyme disease/PTLDS during pregnancy. The placenta will be collected at birth and analyzed by an experienced placental pathologist per a standard protocol. Parent and infant blood will be tested for Lyme disease serology and markers of inflammation.

Following birth, infants will receive an unsedated brain MRI and a cranial ultrasound. The investigators will complete serial developmental evaluations using standardized assessments at multiple timepoints through age 18 months and receive neurological examinations. Throughout the study, participants will also be asked to complete questionnaires including but not limited to topics such as medical history, nutrition, breastfeeding, and socioeconomic information.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lyme disease

Pregnant participants in the "Lyme disease" cohort will meet CDC criteria for clinical and/or laboratory diagnosis of Lyme disease during pregnancy based on stage of disease. Participants will be enrolled following confirmation that they have been diagnosed by a medical professional per CDC guidelines.

Participants in this cohort may be enrolled during any trimester of pregnancy. Live-born infants will be included in the cohort and followed through age 18 months.

Neurodevelopmental assessments and follow-up

Intervention Type OTHER

All infants included in this study will receive standardized neurodevelopmental assessment and neurological examinations through age 18 months.

Post-treatment Lyme Disease Syndrome (PTLDS) or Chronic Lyme

Pregnant participants in the "PTLDS/Chronic Lyme" cohort will have been diagnosed with PTLDS/Chronic Lyme by a health care provider no less than 6 months, but no greater than 3 years, prior to enrollment. Participants will be enrolled following confirmation that they have been diagnosed by a medical professional per CDC guidelines.

Participants in this cohort may be enrolled during any trimester of pregnancy. Live-born infants will be included in the cohort and followed through age 18 months.

Neurodevelopmental assessments and follow-up

Intervention Type OTHER

All infants included in this study will receive standardized neurodevelopmental assessment and neurological examinations through age 18 months.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* English speaker
* Currently reside in the United States or Canada
* Meet CDC criteria for: (1) clinical and/or laboratory diagnosis of Lyme disease during any stage of current pregnancy, OR (2) clinical diagnosis of PTLDS/Chronic Lyme within 3 years of current pregnancy
* Able to be contacted for follow-up

Exclusion Criteria

* Intellectually unable to comprehend study procedures
* Health issues or metallic implant that precludes undergoing MRI
* Incapable of completing study requirements (note: inability to travel to Children's National for in-person follow-up \[for example, due to bedrest, travel restrictions, or financial inability to travel\] is NOT an exclusion criterion; any interested and eligible participants requiring "remote only" participation will be permitted to join the study and complete all requirements besides in-person follow-up)
