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.
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.
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.
In Europe, tick-borne encephalitis (TBE) virus causing TBE is transmitted by the bite of Ixodes ricinus tick, which can also transmit Lyme borreliae , the causative agent of Lyme borreliosis (LB). Since TBE and LB are both endemic with high incidence rates in Slovenia, we should be attentive to the possibility of double infections. Double infections with TBE virus and Lyme borreliae were reported to occur rarely even in endemic countries, however reliable data on coinfection rates are rather limited. Microbiological diagnosis of TBE virus infection is quite straightforward, and there is no specific therapy for TBE available so far. This markedly differs from borrelial infection, in which case interpretation of serological test results demands more caution, but there is highly efficient antibiotic treatment available for LB. This may lead to over prescribing of antibiotics to TBE patients with documented borrelial antibodies in serum indicating possible coinfection with Lyme borreliae, but missing clinical or microbiological criteria for proven borrelial coinfection. Approximately 10% of patients who had been treated appropriately for LB and about one third of patients after TBE report nonspecific subjective complaints, such as fatigue, headache, arthralgia, and myalgia, termed post-Lyme and post-encephalitic symptoms, respectively. These may not be differentiated clearly from nonspecific symptoms occurring with a rather substantial incidence also in the general population. A trend of ascribing medically unexplained nonspecific subjective symptoms to LB in subjects with positive borrelial antibodies in serum puzzles the situation further. The aim of this prospective observational study was to assess the proportion and clinical implication of proven and possible coinfection with Lyme borreliae in patients with TBE, and to evaluate the association between anti-borrelial antibiotic therapy and clinical outcome in the subgroup of patients with possible coinfection.
Approximately 10-20% of patients experience ongoing symptoms despite having received standard antibiotic therapy for Lyme disease. Possible explanations for persistent symptoms include persistent infection and/or post-infectious causes. Recent in vitro studies indicate that disulfiram is effective at killing both the actively replicating and the more quiescent persister forms of Borrelia burgdorferi, the microbe that causes Lyme Disease. In this study, the investigators are examining the safety of disulfiram among patients with post-treatment Lyme disease symptoms. The investigators are also conducting a preliminary investigation regarding the relative benefit of 4 vs 8 weeks of treatment with disulfiram.
The aim of this study is to compare two different serological tests, IFA and LIAISON, for detection of Borrelia burgdorferi sensu lato IgM and IgG antibiodies in children with early disseminated Lyme borreliosis.
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.
