Background: Lyme encephalopathy, characterized by non-specific neurobehavioral symptoms including mild cognitive difficulties, may occur in patients with systemic Lyme disease and is often mistakenly attributed to CNS infection. Identical symptoms occur in innumerable other inflammatory states and may reflect the effect of systemic immune mediators on the CNS. Methods: Multiplex immunoassays were used to characterize the inflammatory profile in serum and CSF from Lyme and non-Lyme patients with a range of symptoms to determine if there are specific markers of active CNS infection (neuroborreliosis), or systemic inflammatory mediators associated with neurobehavioral syndromes...

We investigated potential diagnostic usefulness of serum and cerebrospinal fluid (CSF) concentrations of chemokines CXCL10, CXCL11, and CXCL13 in pediatric patients with acute disseminated encephalomyelitis (ADEM) (n = 23), non-polio enterovirus aseptic meningitis (NPEV AM) (n = 20), and neuroborreliosis (NB) (n = 21) and children with acute infectious diseases with neurological symptoms but with excluded neuroinfection/neuroinflammation (controls, n = 20). CSF levels of CXCL10 and CXCL11 were higher in patients with NPEV AM than those in other children, and CXCL10 levels showed a high discriminative potential (area under the receiver operating characteristic curve, ROC, 0...

The nervous system is involved in 10-15% of patients infected with B. burgdorferi, B. afzelii and B. garinii. This review will address widespread misconceptions about the clinical phenomenology, diagnostic approach and response to treatment of neuroborreliosis. Areas covered: Improvements in diagnostic testing have allowed better definition of the clinical spectrum of neuroborreliosis, with lymphocytic meningitis and uni- or multifocal inflammation of peripheral/cranial nerves predominating. Despite widespread concern that post-treatment cognitive/behavioral symptoms might be attributable to persisting infection or aberrant inflammation within the central nervous system a large body of evidence indicates this is extremely improbable...

We report the case of an 80-year-old patient with acute onset confusion initially suspected to reflect delirium in incipient Alzheimer's disease. Cerebrospinal fluid tests revealed an unusually severe form of neuroborreliosis, which resolved following antibiotic treatment. This was mirrored in the measurement of CXCL13, which is suggested as a complementary biomarker. Clinical implications for screening, differential diagnosis and treatment are discussed.

Lyme neuroborreliosis is the most severe clinical manifestation of Lyme borreliosis. In most of Denmark, and also Europe, the overall prevalence of Lyme borreliosis seems to be stabilising. This is not the case on the island of Funen, Denmark, where the number of human Lyme neuroborreliosis cases has markedly declined throughout the last decade. We propose the reason for the decline is a major epidemic among roe deer, killing almost half of their population, resulting in a reduction in the tick population which make it less likely to get a tick bite and therefore to contract Lyme neuroborreliosis...

BACKGROUND: Cerebrovascular complications of Lyme neuroborreliosis (LNB) are poorly documented in the paediatric population. METHODS: We performed a retrospective analysis from prospectively registered cases of acute ischemic stroke (AIS) from the Swiss NeuroPaediatric Stroke Registry (SNPSR) from 2000 to 2015. Only cases with serologically confirmed LNB were included. In addition, a literature review on paediatric stroke cases secondary to Lyme neuroborreliosis in the same time frame was performed...

Lyme disease is endemic in parts of the United States, including New England, the Atlantic seaboard, and Great Lakes region. The presentation has various manifestations, many of which can mimic psychiatric diseases in children. Distinguishing manifestations of Lyme disease from those of psychiatric illnesses is complicated by inexact diagnostic tests and misuse of these tests when they are not clinically indicated. This article aims to describe manifestations of Lyme disease in children with an emphasis on Lyme neuroborreliosis...

Meningoencephalitis presenting in service personnel overseas may present a diagnostic challenge due to the broad range of potential differential diagnosis as well as the requirement for rapid assessment and treatment. A 25-year-old Royal Marine was evacuated to the Royal Centre for Defence Medicine in Birmingham, UK, with a history of rash consistent with erythema chronicum migrans, a seizure, and lymphocytic pleocytosis after skinning reindeer in Norway. Neuroborreliosis was suspected and empirical antibiotics were administered...

BACKGROUND: The C-X-C motif chemokine ligand 13 (CXCL13) and its receptor CXCR5 play an important role in the homing of B-lymphocytes. As a biomarker in the cerebrospinal fluid (CSF), CXCL13 has increasingly been used for the diagnosis of neuroborreliosis (NB). We evaluated the diagnostic and prognostic potential of CXCL13 for NB and other neuroinflammatory diseases in an unselected cohort, paying attention to those patients particularly who might benefit from newly emerging CXCL13-directed therapies...

BACKGROUND: Tests for direct detection of Borrelia burgdorferi sensu lato (Bb) in Lyme neuroborreliosis (LNB) are needed. Detection of Bb DNA using PCR is promising, but clinical utility is hampered by low diagnostic sensitivity. We aimed to examine whether diagnostic sensitivity can be improved by the use of larger cerebrospinal fluid (CSF) volumes and faster handling of samples. METHODS: Patients who underwent CSF examination for LNB were included. We collected two millilitres of CSF for PCR analysis, extracted DNA from the pellets within 24 h and analysed the eluate by two real-time PCR protocols (16S rRNA and OspA)...

The spirochete bacterium Borrelia burgdorferisensu lato is the causative agent of Lyme disease, the most common vector-borne disease in Europe and the United States. The spirochetes can be transmitted to humans via ticks, and then spread to different tissues, leading to arthritis, carditis and neuroborreliosis. Although antibiotics have commonly been used to treat infected individuals, some treated patients do not respond to antibiotics and experience persistent, long-term arthritis. Thus, there is a need to investigate alternative therapeutics against Lyme disease...

Background: Despite a well-described symptomatology, treatment delay and sequelae are common in patients with Lyme neuroborreliosis (LNB). The aim of this study was to contribute to the knowledge about the symptomatology and epidemiology of LNB. Methods: We conducted a retrospective study of all LNB cases verified by a positive Borrelia intrathecal antibody index test performed at the Department of Microbiology, Odense University Hospital, Denmark, from 1995 through 2014...

Immunoglobulin gamma (IgG) heavy chain genes are associated with susceptibility to multiple sclerosis (MS) and IgG levels in the cerebrospinal fluid (CSF). However, how these variants are implicated in disease mechanisms remains unknown. Here, we show that proliferating plasmablasts expressing the G1m1 allotype of IgG1 are selectively enriched in CSF of G1m1/G1m3 heterozygous MS patients, whereas plasmablasts expressing either G1m1 or G1m3 are evenly distributed in blood. Moreover, there was a preferential intrathecal synthesis of oligoclonal IgG1 of the G1m1 allotype in heterozygous patients, whereas controls with Lyme neuroborreliosis displayed oligoclonal IgG1 of both allotypes...

Introduction. Lyme borreliosis is a multisystem tick-borne disease caused by Borrelia burgdorferi. Neurological manifestations are reported in up to 15 % of adult patients with Lyme disease, while the frequency among children is higher. The most common manifestations are painful radiculopathy, facial nerve paresis and lymphocytic meningitis. Epileptic seizures and cerebral vasculitis with stroke or aneurysms are very rare complications. Case presentation. We describe a paediatric patient with sensorineural auditory dysfunction, headache, fatigue and epileptic seizures as sequelae of meningoencephalitis/Lyme neuroborreliosis (LNB) caused by B...

OBJECTIVES: Tick-borne encephalitis virus (TBEV) is a zoonotic agent causing severe encephalitis. In 2016, in Northeastern France, we faced a TBEV infection increase, leading to a warning from the Regional Health Agency. Here, we report the confirmed TBE cases diagnosed between January 2013 and December 2016, with particular emphasis on the year 2016. METHODS: A total of 1643 blood and cerebrospinal fluid (CSF) samples from everywhere in France, corresponding to 1460 patients, were prospectively tested for anti-TBEV-specific IgM and IgG antibodies by ELISA...

Lyme neuroborreliosis (LNB), which is the most common neurological manifestation of Lyme disease (LD), seriously impairs both the central and peripheral nervous systems. Current LNB diagnostic methods and criteria are not very effective. Recently, several studies have indicated that a high concentration of the chemokine CXC ligand 13 (CXCL13) in cerebrospinal fluid (CSF) could be used as a new biomarker for the diagnosis of LNB. Thus, we carried out a meta-analysis to systematically analyze the data from these studies to evaluate the value of CXCL13 as an LNB biomarker...

BACKGROUND: Lyme borreliosis (LB) is a tick-borne infection caused by Borrelia burgdorferi sensu lato. The most frequent clinical manifestations are erythema migrans and Lyme neuroborreliosis. Currently, a large volume of diagnostic testing for LB is reported, whereas the incidence of clinically relevant disease manifestations is low. This indicates overuse of diagnostic testing for LB with implications for patient care and cost-effective health management. AIM: The recommendations provided in this review are intended to support both the clinical diagnosis and initiatives for a more rational use of laboratory testing in patients with clinically suspected LB...

Lyme neuroborreliosis is a nervous system infectious disease caused by Borrelia burgdorferi (B. burgdorferi). It has been demonstrated that cytokines induced by B. burgdorferi are related to Lyme neuroborreliosis. Microglia is known as a key player in the immune responses that occur within the central nervous system. In response to inflammation, it will be activated and generate cytokines and chemokines. Experiments in vitro cells have showed that B. Burgdorferi membrane protein A (BmpA), a major immunogen of B...
