Title:

Microarray Analysis of Erythema Migrans Lesions

Number:

05-I-0219

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. 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, 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.

Recruitment Detail

Type: Participants currently recruited/enrolled

Gender: Male & Female

Referral Letter Required: No

Population Exclusion(s): Children

Eligibility Criteria:

INCLUSION CRITERIA:

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.

Not know to be positive for RPR, HIV, HBsAg or HCV
