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

      <textblock>
        Childhood neurodevelopmental outcomes following antenatal Lyme disease exposure are not yet&#xD;
        known. This pilot study will lay the groundwork for a larger study to determine the effect of&#xD;
        in utero exposure to Lyme disease on pregnancy and early childhood neurodevelopmental&#xD;
        outcomes. Understanding the effects on the developing brain is essential in order to inform&#xD;
        timely prenatal and postnatal treatments to protect the fetus exposed to Lyme disease during&#xD;
        pregnancy. Once childhood neurodevelopmental outcomes are known, appropriate follow-up and&#xD;
        treatment guidelines can be developed to help better support children's developmental needs.&#xD;
  &#xD;
        The primary aim of this study is to assess the feasibility of longitudinal follow-up of&#xD;
        fetuses and infants exposed to Lyme disease in utero.Lyme disease in pregnancy and the impact&#xD;
        on the fetus/child following in utero exposure has been identified as a priority research&#xD;
        area; this pilot study is the essential step to plan a large study that will fill this&#xD;
        knowledge gap and make a substantial contribution to the field.&#xD;
  &#xD;
        The investigators will perform a prospective pilot longitudinal cohort study of B.&#xD;
        burgdorferi-infected parents and their in-utero-exposed fetuses/infants. Patients included in&#xD;
        this study will have a clinical diagnosis of Lyme disease during gestation or have been&#xD;
        diagnosed with Lyme disease and/or PTLDS within 3 years preceding pregnancy.&#xD;
  &#xD;
        Pregnant participants will receive a fetal MRI and ultrasound during the second or third&#xD;
        trimesters of gestation. The investigators will conduct optional qualitative interviews with&#xD;
        interested participants during their 3rd trimester to gather additional data on their&#xD;
        experiences with Lyme disease/PTLDS during pregnancy. The placenta will be collected at birth&#xD;
        and analyzed by an experienced placental pathologist per a standard protocol. Parent and&#xD;
        infant blood will be tested for Lyme disease serology and markers of inflammation.&#xD;
  &#xD;
        Following birth, infants will receive an unsedated brain MRI and a cranial ultrasound. The&#xD;
        investigators will complete serial developmental evaluations using standardized assessments&#xD;
        at multiple timepoints through age 18 months and receive neurological examinations.&#xD;
        Throughout the study, participants will also be asked to complete questionnaires including&#xD;
        but not limited to topics such as medical history, nutrition, breastfeeding, and&#xD;
        socioeconomic information.&#xD;

The fronto-occipital and biparietal cerebral diameters, cerebellar vermis and diameter, and corpus callosum length will be measured. Biometric measurements and estimation of fetal cortical maturation will be compared with age-expected norms. Fetal ultrasound will be used to evaluate measurements of cerebral head circumference, biparietal diameter, body biometry, and interval growth between research scans. Fetal head circumference z-scores will be calculated from US measurements based on gestational age using the Hadlock method.
  measure: Infant neuroimaging (Magnetic resonance imaging [MRI] and ultrasound) analysis
  time frame: Child age: Between 2-8 weeks
  description: At 2-8 weeks of age, infants will have an unsedated brain MRI and a cranial ultrasound scan. Based on investigator experience, the majority of infants can have a successful brain MRI without sedation at <6 weeks of age. The brain MRI protocol will be the standard clinical infant protocol at Children's National Hospital that includes T1, T2, susceptibility weighted imaging, and diffusion sequences. The brain MRI is without contrast.
  arm group label: Lyme disease
  description: 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.
  arm group label: Post-treatment Lyme Disease Syndrome (PTLDS) or Chronic Lyme
  description: 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.
  intervention type: Other
  intervention name: Neurodevelopmental assessments and follow-up
