Evaluation and Follow-up of People With Tick-borne Diseases


Background: Lyme disease is the most common tick-borne disease in the United States, but other diseases transmitted by ticks have also been on the rise in recent years. Early symptoms of a tickborne disease include fever, headache, fatigue and possible rash. Researchers want to collect information and samples from people with Lyme disease and other tick-borne illnesses to better understand and diagnose these diseases. Objective: To evaluate and follow people with tick-borne diseases to help researchers learn more about these infections. Eligibility: People ages 18 and older who have or are suspected of having a tick-borne infection. Design: Participants will have an initial visit, and visits about 1, 6, and 12 months later. The visits can include a physical exam, blood tests, collection of blood, urine and saliva samples for research, and filling out health-related questionnaires. Participants who have the rash of Lyme disease may be invited to have up to 3 skin punch biopsies of the rash for research.

Detailed Description

Lyme disease is a multisystem illness caused by the spirochete Borrelia burgdorferi and it is the most common vector-borne illness in the United States. Tick-borne disease cases reported to the Center for Disease Control and Prevention (CDC) have been on the rise with over 59,000 cases reported in 2017. This protocol is designed to collaborate with University of Maryland School of Medicine for the purpose of recruiting and enrolling patients with Lyme disease and other tickborne illnesses. This is a natural history study which has the objective of developing a rigorously defined population of patients with Lyme disease and other tick-borne illnesses, per CDC case definitions, to serve as the basis for research in multiple aspects of the infections. These research sub-projects have emphasis in exploring the biological markers of tick-borne infections, developing new diagnostic tests for these infections, assessing the clinical course and outcome of patients with these tick-borne infections, and defining the immunological response to the pathogens.
