Lyme borreliosis is a bacterial multisystemic infection transmitted by an Ixodes tick. It affects the skin, the joint and the brain. At the early phase, the diagnosis is clinical, relying on the presence of an erythema migrans at the site of the tick bite. The diagnosis of disseminated infections, more difficult to assess, mainly relies on indirect diagnosis test, i.e. serology. This study will evaluate a new direct diagnosis method based on proteomics, which aims to demonstrate proteins of live bacteria in the skin and the synovial or cerebrospinal fluids in a direct manner.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Lyme Disease
Lyme arthritis resolves with appropriate antimicrobial treatment in a majority of patients, but 10-20% of patients develop antibiotic-refractory Lyme arthritis with prolonged arthritis symptoms and treatment courses. Excessive up-regulation of the inflammatory process has been shown in patients with antibiotic-refractory Lyme arthritis. The over-expressed pro-inflammatory cell mediators are downstream of NSAID inhibition, which would suggest initial inflammatory inhibition may be beneficial in these patients. While NSAIDs are known to reduce pro-inflammatory cell mediators early in the course of inflammation, research has shown that there are other cytokines that play a role in the healing after inflammation that are also inhibited by NSAIDs, and that NSAID use can delay healing. It is not known if scheduled NSAID therapy will reduce, increase, or have no effect on the occurrence of refractory Lyme arthritis cases. The hypothesis of the study is that prescribing scheduled NSAIDs at the time of diagnosis of Lyme arthritis can prevent the development of the excessive inflammatory phase and decrease the number of patients with antibiotic-refractory Lyme arthritis, or at least decrease the duration of persistent Lyme arthritis symptoms. The pilot study design randomizes patients to scheduled NSAIDs, scheduled acetaminophen, or scheduled NSAIDs x 1 week than acetaminophen. Primary outcomes are duration of arthritis symptoms, number of refractory cases, side effects and compliance.
Neuroborreliosis (NB) is the second most frequent manifestation of Lyme disease. Painful meningoradiculitis is the most common neurologic manifestation in adults while facial nerve palsy (FP) and lymphocytic meningitis is predominant in children. FP is a common reason for pediatric consultation and FP due to Lyme borreliosis (LB) represents about 50% of the child's FP in an endemic area. The action to be taken is not formally defined for a child consulting for FP in a Lyme disease endemic area. The new recommendations of the High Authority of Health of June 2018 recommend to carry out a blood serology in first intention, in search of a NB in a child consulting for a peripheral facial paralysis. If this is positive, a lumbar puncture will be performed in search of meningitis. In the case of negative serology, a close clinical surveillance and sometimes serological control is necessary, in order to reassess the diagnosis. In adult recommendations, a lumbar puncture is performed first in any patient consulting for facial paralysis in LB endemic area. The main objective of this study was to describe the clinical and biological characteristics of pediatric NB with FP. Others objectives were to describe the diagnostic and therapeutic behavior of a child consulting at university hospital for a facial nerve palsy, to compare the initial gravity of facial nerve palsy, the duration of the paralysis and sequels depending on the diagnosis and treatment initiated.
There are more than 300,000 new cases of Lyme disease every year in the US. Lyme disease is a dangerous bacterial infection transmitted by tick bites and it becomes increasingly severe as the infection progresses. Definitive diagnosis is based on serum-based tests that have fundamental limitations: 1) current tests cannot detect early infections so patients do not receive antibiotic therapy until the infection has progressed, and 2) there is no way to measure if antibiotic therapy has been successful. MicroB-plex will address these two unmet clinical needs by introducing a novel, blood-based diagnostic method that will enable clinicians to diagnose infections earlier and to monitor the success of their interventions.
Lyme disease is due to Borrelia burgdorferi sensu lato and is transmitted by a tick vector of the genus Ixodes. One of the clinical forms of this disease in the disseminated phase is the appearance of arthritis, classically mono or oligo-arthritis in the large joints.
Ticks are the major arthropod vectors transmitting pathogenic agents to humans and domestic animals in Europe, and currently, the incidence of tick-borne disease is rising. The most common European human tick-borne disease is Lyme borreliosis, with an estimated 90 000 new cases every year (compared to 300 000 new cases in the United States annually). This disease is initially clinically diagnosed by the presence of migrating erythema following a tick bite, which is then subsequently confirmed by serological tests. In parallel with classic Lyme borreliosis cases, tick-bitten patients can also present with polymorphic and on-specific clinical symptoms (asthenia, fever, myalgia, etc. …) for which there is no known etiological diagnosis. It is extremely difficult to determine the proportion of tick-bitten patients with these symptoms compared to patients which have actually contracted Lyme disease, although it is estimated that 50% of fevers following a tick bite have an unknown infectious origin. Typical tick habitats are woodlands, prairies, pastures, and gardens. Ticks are extremely sensitive to environmental fluctuations, which are often brought about by human socio-economic changes, thus tick-borne diseases are excellent candidates for emergence. Consequently, it is incontestable that tickborne diseases pose a significant threat to our society. In addition to improving diagnostic techniques, one of the major hurdles relates to improving public and health professional knowledge about tick disease risk. The battle against tick-borne diseases is based on relatively simple prevention measures, and their effectiveness is immeasurably improved when citizens are more informed and involved.Therefore, a multidisciplinary project, bringing together veterinarians, doctors, scientists, and consultant sociologists has been designed to create a global "One Health" approach to tick-borne diseases. Specific scientific project objectives are to (1) detect, identify, and isolate new microorganisms—both unknown or unexpected—from patients or animals suffering from unexplainable symptoms following tick bites; (2) to demonstrate tick competence in their ability to transmit these agents; and (3) to generate concrete recommendations to improve tick-borne disease management.
The Danish Study Group of Infections of the Brain is a collaboration between all departments of infectious diseases in Denmark. The investigators aim to monitor epidemiological trends in central nervous system (CNS) infections by a prospective registration of clinical characteristics and outcome of all adult (>17 years of age) patients with community-acquired CNS infections diagnosed and/or treated at departments of infectious diseases in Denmark since 1st of January 2015.
