Brief Summary:
This study will determine whether patients who have been infected with the Lyme bacteria Borrelia burgdorferi and treated with antibiotics still have the bacteria alive inside them and whether it is causing their symptoms The information from this study may serve as a basis for developing stringent diagnostic criteria for Lyme disease and the establishment of future treatment trials
Individuals in the following categories may be eligible for this study chronic Lyme disease chronic Lyme arthritis seropositive control are infected with the bacteria that causes Lyme disease but do not have disease symptoms recovered control have been sick with Lyme disease but were treated successfully and are currently well control with multiple sclerosis patients with multiple sclerosis and healthy volunteers Patients in the chronic Lyme disease category must be age 13 and above all others must be age18 and above Candidates will be screened with blood and urine tests
Participants will have a physical examination and the following tests
Blood tests Includes HLA-typing a genetic test of immune system markers
Leukapheresis Collection of large numbers of white blood cells Whole blood is collected through a needle in an arm vein The blood circulates through a machine that separates it into its components The white cells are removed and the rest of the blood is returned to the body either through the same needle used to draw the blood or through another needle in the other arm Alternatively patients will 100 cc about 7 tablespoons of blood drawn
Lumbar puncture spinal tap Collection of cerebrospinal fluid CSF fluid that bathes the brain and spinal cord A local anesthetic is administered and a needle is inserted in the space between the bones in the lower back where the cerebrospinal fluid circulates below the spinal cord A small amount of fluid is collected through the needle
Magnetic resonance imaging MRI of the brain Imaging of the brain using a strong magnetic field and radio waves instead of X-rays During the scan the patient lies on a table in a narrow cylinder containing a magnetic field He or she can speak with a staff member via an intercom at all times during the procedure
Neuropsychologic testing
Some participants may also have a hearing test and urine collection
Participants whose test results are positive for Borrelia burgdorferi will be followed at NIH at intervals of 3 to 6 months until it is determined whether there is infection Those who are infected will be offered treatment with the antibiotic ceftriaxone Following treatment patients will return to the NIH Clinical Center for follow-up visits 1 week after treatment and again at 3 6 and 12 months The lumbar puncture hearing examination blood and urine tests will be repeated at these visits to evaluate the response to treatment and the leukapheresis will be repeated for research purposes Patients whose MRI was abnormal during therapy will have a repeat MRI at the 3-month 6-month and 1-year visits
All participants with chronic Lyme disease chronic Lyme arthritis seropositive controls and recovered controls may be reevaluated at intervals of 6 to 12 months

Detailed Description:
Lyme disease has emerged as the leading vector-borne disease in the United States Despite how much has been learned about Lyme borreliosis in the past decade there are still many remaining areas of uncertainty One fundamental question is whether persistent signs and symptoms of disease despite the administration of what is currently considered to be adequate antibiotic therapy are due to ongoing active borrelial infection to a post-infectious syndrome to irreversible sequelae of earlier tissue injury or due to a condition unrelated to Lyme disease Reliable objective markers of infection of clinical status and of host responses to the organism are required to discern the scope and the implications of persistent borrelial infection the effectiveness of current treatment options and the development of new therapeutic approaches The goal of this study is to assemble and follow a well-characterized cohort of patients with post-treatment Lyme disease syndrome and relevant controls that will yield a prospective database upon which stringent diagnostic criteria can be established and future therapeutic trials can be designed
