Active clinical trials for "Lyme Disease"

This randomized, controlled study examines whether a daily practice over 8 weeks of Kundalini Yoga or Meditation can help to reduce pain and/or fatigue among patients with symptoms that persist despite prior antibiotic treatment.

In the Main Study Phase a total of 246 subjects were randomized 2:2:1 into three treatment groups to receive either VLA15 with Alum (lower or higher dose) or Placebo. Main Study Phase vaccinations were administered as intramuscular injections on Day 1, Day 57 and Day 180. In the Booster Phase subjects from the higher dose group who completed their primary immunization schedule according to protocol will be randomized 2:1 to receive an additional higher dose VLA15 vaccination or Placebo at Month 18. Study duration in the Main Study Phase per subject is a maximum of 20 months. Overall study Duration is estimated to be 22 months. Study duration per subject in the Booster Phase is a maximum of approximately 13 months. Study duration per subject in the Main Study Phase and Booster Phase together is estimated to be a maximum of approximately 33 months. Overall study duration (i.e., First-Subject-In to Last-Subject Out/ end of Booster Phase) is estimated to be approximately 37 months.

Section 1: The purpose of the study is to obtain safety and immunogenicity data of different dose levels of a multivalent recombinant OspA Lyme Borreliosis (mv rOspA LB) Vaccine with and without adjuvant in seronegative healthy adults aged 18 to 70 years. The outcome shall provide the basis for dose/formulation selection for Section 2 of the study. Section 2: An additional purpose of the study is to evaluate the safety and immunogenicity of the optimal dose(s)/formulation of the mv rOspA LB Vaccine in a larger population of seronegative and seropositive healthy subjects aged 18 to 70 years.

The main purpose of this study is to compare effectiveness of two different culture media for cultivation of Borrelia burgdorferi sensu lato from skin specimens obtained from patients with erythema migrans.

Background: The most common tick-borne illness in the United States, Lyme disease is caused by Borrelia burgdorferi bacteria that are transmitted to people by Ixodes scapularis ticks. Most cases of Lyme disease are cured by antibiotics, but some patients continue to experience symptoms despite the absence of detectable Lyme bacteria. Xenodiagnosis uses a vector to detect the presence of a disease-causing microbe.. Researchers will use live, laboratory-bred ticks to see if Lyme disease bacteria can be detected in people after completing antibiotic therapy and if that is more common in people who continue to experience symptoms such as fatigue and joint pain. Objectives: - To see if ticks can be used to detect B. burgdorferi in people who have had Lyme disease and received antibiotic therapy and if it correlates with persistent symptoms. Eligibility: Adults at least 18 years old who have: Untreated erythema migrans (the Lyme disease rash); OR Untreated Lyme arthritis; OR Continuing symptoms after treatment for Lyme disease; OR Had Lyme disease and antibiotic treatment within the past 12 months. Healthy volunteers Design: Participants will be screened with medical history, physical exam, and blood tests. Visit 1: Blood and urine tests, health questionnaire. Up to 30 laboratory-bred, pathogen-free, larval ticks (each smaller than a poppy seed) will be placed under a dressing. Participants may have two small biopsies of skin . 4 6 days later, Visit 2: Dressing will be removed and ticks will be collected. Participants will answer symptom questions. If many ticks are still attached, participants will have to come back the next day. If not enough ticks feed successfully, the procedure may be repeated. Participants will keep a diary of symptoms for 30 days. Over 3 months, they will be return to the clinic 3 times to see how they feel and answer questionnaires. Test results will be discussed.

Observer-blind, partially randomized, multi-center dose escalation Phase I study in healthy adults below 40 years of age. 180 subjects will be enrolled in 6 treatment groups (different doses; different formulation: with/without adjuvant); vaccinations will be given I.M.(intramuscular) into the deltoid region on Days 0, 28 and 56. Study participants will be followed up until one year after first vaccination. Booster Extension: Subjects in the 48µg and 90µg Treatment groups who received a complete Primary immunization schedule will be included into a Booster Extension 13 months after the first immunization.

This is a randomized, observer-blind, placebo controlled, multicenter Phase 2 study conducted in two study phases: a run-in phase and a main study phase. The study was investigated 3 doses of a multivalent OspA (Outer Surface Protein A) based Lyme vaccine (VLA15) in healthy adults aged 18 to 65 years of age. Study participants received 3 immunizations of the vaccine at a monthly interval. The study assessed the immune response as well as the safety profile of the vaccine.

Background: Lyme disease is an infection caused by Borrelia burgdorferi, a bacteria that is transmitted to humans by ticks. It can cause many different symptoms including rash, fever, headache, meningitis (infection of the central nervous system), and arthritis. While most patients improve after taking antibiotics, some patients continue to have symptoms. It is currently unknown why some patients continue to have symptoms. One possibility is that the antibiotics have not successfully gotten rid of all of the bacteria. Current tests for Lyme disease cannot tell whether the bacteria have been successfully eliminated from the body. Xenodiagnosis is a way to look for Borrelia bacteria using the animal that usually hosts them, Ixodes scapularis (also known as the deer tick). This method takes advantage of the evolution of the bacteria and the insect that transmits the infection, which can make the insect particularly good at finding the agent. In studies of animals, xenodiagnosis may be more sensitive than current tests for detecting the presence of the Lyme disease bacteria. Researchers are interested in using xenodiagnosis to determine whether uninfected ticks that feed on humans who have been infected with Lyme disease bacteria can detect the continued presence of live bacteria. Objectives: - To determine whether xenodiagnosis can be used to successfully investigate the presence of Lyme disease bacteria. Eligibility: Individuals at least 18 years of age who are in one of the following categories: Have had the erythema migrans rash (a symptom of Lyme infection) and received antibiotic therapy less than 4 months ago (but have not had antibiotics in the previous month). Have the erythema migrans rash and received less than 2 days of antibiotic therapy. Have been diagnosed with early or late Lyme disease, have received antibiotic therapy, but still have high levels of antibodies against the bacteria at least 6 months after therapy, and have not received antibiotics in the past 3 months. Have been diagnosed with early or late Lyme disease, have received antibiotic therapy, and have new complaints of fatigue or other symptoms that are persistent for at least 6 months after completion of antibiotic therapy, and have not received antibiotics in the past 3 months. Have been diagnosed with Lyme arthritis and have not yet received antibiotic therapy. Healthy volunteers who have not had Lyme disease will also be included in this study. Design: Participants will have an initial visit for a physical examination, medical history, and blood sample. For the first study visit, researchers will place a strip of filter paper or a small plastic container with 20 to 30 disease-free ticks on the participant s skin. If possible, the ticks will be placed at the site of a Lyme disease rash or another suspicious area, or on the nondominant forearm. Participants will be asked to keep the ticks in place, and will keep a diary card at home to record any symptoms or problems. The ticks will be collected 4 to 6 days after placement. At that visit, participants will have a skin biopsy taken of the area tested, a blood sample will be collected, and participants will receive a new diary card to keep until the next clinic visit. After 1 month, participants will provide a final blood sample, and will receive a follow-up phone call 2 months afterward.

Our overall purpose of this study is evaluate whether a short in-class Lyme Disease education program based on social learning theory and the Health Belief Model can impact a child's knowledge, attitude, and preventive behavior. 1. Deliver an educational program in schools to promote personal protective practices, encourage early disease detection and modify residential habitats to reduce tick density. 3. Evaluate the program's efficacy by comparing the acceptability and practice of precautionary behavior, tick density in residential areas and rates of Lyme disease between groups using primary and surveillance data sources Evaluate the contribution of knowledge, attitudes, and parental involvement to children's adoption of prevention strategies. Hypothesis The community intervention will reduce the incidence of Lyme disease among children and families living in endemic areas by increasing the practice of precautionary behavior and reducing tick density in residential areas. Specifically, we hypothesize that: The educational intervention will reduce the incidence of Lyme disease among children and families living in an endemic area. The educational intervention will improve the childrens' self-confidence (behavioral self-efficacy), intention to perform, and actual practice of Lyme disease prevention behaviors.

The T2Lyme assay will be compared to Borrelia culture from erythema migrans (EM) biopsy and/or detection of the C6 antigen in serum collected prospectively from patients suspected of early Lyme disease.
