Trial summary

This study will analyze cells from erythema migrans lesions, the "bull's eye" rash of Lyme disease. Little is known about what happens in the skin when it is infected with Borrelia burgdorferi, the bacteria that cause Lyme disease. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Patients:
  • Age greater than or equal to 18 years
  • Diagnosis of EM - an expanding annular lesion, at least 5 cm in diameter on a person with a history of exposure to the disease.
  • Exposure is defined as having been (less than or equal to 30 days before onset of EM) in wooded, brushy, or grassy areas (i.e., potential tick habitats) in an area in which Lyme disease is endemic.
  • A history of tick bite is not required.
  • The area of the erythema migrans lesion is suitable for biopsy. This excludes biopsies on the face, neck, scalp, and over the tibia.

About this study

Official title: Analysis of Erythema Migrans Lesions

This study will analyze cells from erythema migrans lesions, the "bull's eye" rash of Lyme disease. Little is known about what happens in the skin when it is infected with Borrelia burgdorferi, the bacteria that cause Lyme disease. This study will examine and compare laboratory findings in skin biopsies from people with Lyme disease and from healthy normal volunteers to try to better understand the infection.

Healthy volunteers and people with untreated erythema migrans rash who are 18 years of age or older may be eligible for this study.

All participants undergo a clinical examination, blood tests, between two to four skin biopsies (removal of a small piece of tissue for laboratory examination), and complete two health questionnaires. The biopsies are taken from the erythema migrans lesion in patients with Lyme disease and from skin on the legs, forearms, buttocks, or side from healthy volunteers. To collect the tissue, the skin at the biopsy site is numbed with injection of a local anesthetic and a sharp instrument is then used to remove a round plug of skin about the size of a pencil eraser. The wound may be closed with one or two sutures, or allowed to heal without sutures. The sutures are removed after a week to 10 days.

Patients with Lyme disease receive treatment for their condition. In addition, at the time the sutures are removed and at 4 weeks, 6 months, and 12 months after their first visit they fill out a questionnaire and have additional blood tests.

Read the detailed description

Little is known of the host and the bacteria response in vivo in patients with Lyme disease. In an attempt to better understand the pathology of erythema migrans (EM), we will use a variety of techniques to characterize patterns in skin biopsies from individuals with a diagnosis of EM and compared those to the patterns seen in biopsies from unaffected individuals. Biopsies from patients may also be evaluated for B. burgdorferi. Patients diagnosed with erythema migrans will have between 2 and 4 punch skin biopsies of affected area, and will return for 4 follow up visits in the course of a year. Therapy for Lyme disease will be offered. Healthy volunteers will have a screening visit, a visit for the skin biopsies and a follow up visit. Patients and healthy volunteers will be compensated for their time and inconvenience.

Questions about this trial

What is this clinical trial studying?

An observational study of Erythema Migrans Lesions and Erythema Migrans, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00132327, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2018.
