Nervous system lyme disease

Xenia Naj, Stefan Linder
The spirochete Borrelia burgdorferi is the causative agent of Lyme disease, a multisystemic disorder affecting primarily skin, nervous system, and joints. If an infection with Borrelia proceeds unchecked, the disease can also enter a chronic stage, leading to the development of neuroborreliosis or cardiac arrhythmia. Successful elimination of B. burgdorferi by the host immune system is thus decisive for the positive outcome of a respective infection. Accordingly, host immune cells such as macrophages and dendritic cells have to be able to efficiently internalize and degrade infecting spirochetes...

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. According to the Centers for Disease Control and Prevention, it is the most commonly reported vector-borne illness and the fifth most common disease in the National Notifiable Diseases Surveillance System. If left untreated, infection disseminates to the nervous system. The nonhuman primate model of Lyme disease of the nervous system, or Lyme neuroborreliosis, accurately mimics the aspects of the human illness...

Pyrokinin-related peptides are pleiotropic factors that are defined by their conserved C-terminal sequence FXPRL-NH2. The pyrokinin nomenclature derives from their originally identified myotropic actions and, as seen in some family members, a blocked amino terminus with pyroglutamate. The black-legged tick, Ixodes scapularis, is well known as a vector of Lyme disease and various other illnesses; however, in comparison to blood-feeding insects, knowledge on its physiology (along with other Ixodid ticks) is rather limited...

White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). The pathogenesis of many white matter diseases remains poorly understood. Demyelinating disorders are the object of this review and will be further divided into autoimmune, infectious, vascular, and toxic-metabolic processes. Autoimmune processes include multiple sclerosis and related diseases: tumefactive demyelinating lesions, Balo concentric sclerosis, Marburg and Schilder variants, neuromyelitis optica (Devic disease), acute disseminated encephalomyelitis, and acute hemorrhagic leukoencephalopathy (Hurst disease)...

Today, Lyme disease is the most commonly reported tick-borne disease in the United States and Europe. The culprits behind Lyme disease are the Borrelia species of bacteria. In the USA, Borrelia burgdorferi causes the majority of cases, while in Europe and Asia Borrelia afzelii and Borrelia garinii carry the greatest burden of disease. The clinical manifestations of Lyme disease have been identified as early localized, early disseminated, and late chronic. The neurological effects of Lyme disease include both peripheral and central nervous systems involvement, including focal nerve abnormalities, cranial neuropathies, painful radiculoneuritis, meningitis, and/or toxic metabolic encephalopathy, known as Lyme encephalopathy...

Lyme disease is caused by a tick-transmitted spirochete, B. burgdorferi. It can present with both central and peripheral nervous system manifestations, including aseptic meningitis, meningoencephalitis, Bell's palsy and other cranial neuropathies, radiculoneuritis, and myelitis. However, pseudotumor cerebri associated with Lyme disease is rare. Here, we report a eight-year-old girl with the unusual manifestation of pseudotumor cerebri associated Lyme disease.

Lyme disease, caused by the spirochete Borrelia burgdorferi (Bb), is the most common vector-borne illness in the United States. It is a complex disease which may affect the skin, joints, heart, eyes, and central nervous system. Prompt diagnosis and treatment is curative in most instances. However, a significant percentage of patients experience ongoing symptoms after treatment. Currently, there is much controversy regarding the diagnosis, pathophysiology, and treatment of Lyme disease. Pathogen persistence despite treatment lies at the heart of this debate...

Lyme disease is a chronic infectious disease caused by the bacteria, spirochete of the Borrelia type. Skin, nervous system, musculoskeletal system and heart may be involved in the course of the disease. The prognosis for properly treated Lyme disease is usually good. However, in about 5% of patients so called Post-Lyme disease syndrome (PLSD) develops. It is defined as a syndrome of subjective symptoms persisting despite proper treatment of Borrelia burgdorferi infection. The most common symptoms include: fatigue, muscle and joint pain, and problems with memory and concentration...

Optic neuritis (ON) is one of the most common manifestations of central nervous system involvement caused by various etiologies. Lyme ON is an exceedingly rare ocular manifestation of Lyme disease (LD) and only a few cases have been published in the literature. Lyme ON is very rare but should be included in the differential diagnosis in unexplained cases, particularly in Lyme endemic areas. Careful and detailed examination and investigation are warranted to make the diagnosis. We report this case to increase awareness of clinicians to include Lyme disease in differential diagnosis of ON for unexplained cases of ON...

PURPOSE OF REVIEW: Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common tick-borne illness in the United States and Europe. Lyme disease usually begins with the characteristic skin lesion, erythema migrans, at the site of the tick bite. Following hematogenous dissemination, neurologic, cardiac, and/or rheumatologic involvement may occur. Neurologic involvement occurs in up to 15% of untreated B. burgdorferi infection and neurologists should be familiar with its diagnosis and management...

Lyme borreliosis, infection with the tick-borne spirochete Borrelia burgdorferi sensu lato, causes nervous system involvement in 10-15 % of identified infected individuals. Not unlike the other well-known spirochetosis, syphilis, infection can be protracted, but is microbiologically curable in virtually all patients, regardless of disease duration. Diagnosis relies on 2-tier serologic testing, which after the first 4-6 weeks of infection is both highly sensitive and specific. After this early, acute phase, serologic testing should rely only on IgG reactivity...

Borrelia burgdorferi is the causative agent of Lyme disease, a multisystemic disorder affecting the skin, joints, and nervous system. Macrophages and dendritic cells counteract Borrelia dissemination through internalization and degradation of spirochetes. We now show that Borrelia internalization by primary human macrophages involves uptake and compaction into Rab22a-positive phagosomes that are in close contact with Rab5a-positive vesicles. Compaction of borreliae involves membrane extrusion from phagosomes, is driven by Rab22a and Rab5a activity, and is coordinated by ER tubules forming contact sites of Rab22a phagosomes with Rab5a vesicles...

Lyme disease can affect the central nervous system causing a B-cell-predominant lymphocytic pleocytosis. Since most reactions to infection in the cerebrospinal fluid (CSF) are typically T-cell predominant, a B-cell-predominant lymphocytosis raises concern for lymphoma. We present 3 Lyme neuroborreliosis cases in order to illustrate the challenging cytomorphological and immunophenotypic features of their CSF specimens. Three male patients who presented with central nervous system manifestations were diagnosed with Lyme disease...

Lyme disease is the most common tick-borne illness in the Northern hemisphere and is caused by spirochetes of the Borrelia burgdorferi sensu lato complex. A first sign of Borrelia infection is a circular skin rash, erythema migrans, but it can develop to more serious manifestations affecting skin, nervous system, joints, and/or heart. The marked increase in Lyme disease incidence over the past decades, the severity of the disease, and the associated high medical costs of, in particular, the persistent forms of Lyme disease requires adequate measures for control...

Lyme neuroborreliosis (LNB) is an infectious disease of the nervous system caused by the tick-borne spirochete Borrelia burgdorferi. The presence of B. burgdorferi specific antibodies in cerebrospinal fluid (CSF), with evidence of intrathecal production, is the traditional diagnostic standard, although has limitations it such as low sensitivity in the very early phase. In the current study, 27 patients with possible neuroborreliosis suffered from clinically defined Bannwarth syndrome. The control group (CON) consisted of 6 patients...

Chronic intestinal pseudoobstruction is often classified as idiopathic. The condition is associated with poor quality of life and high morbidity, and treatment options are often unsatisfactory. A case of chronic intestinal pseudoobstruction in a 66-year-old woman, presenting with back and abdominal pain, urinary retention and severe constipation is described. The patient lived in an area in which Lyme disease is endemic and had been bitten by ixodes ticks. Intrathecal synthesis of anti-borrelia IgM and IgG and lymphocytosis in the cerebrospinal fluid was found, consistent with chronic Lyme neuroborreliosis since symptoms had lasted for more than six months...

INTRODUCTION: Lyme neuroborreliosis (LNB) is a tick-borne infection of the nervous system caused by the spirochete Borrelia burgdorferi sensu lato. The primary symptoms are usually painful radiculitis, facial palsy and lymphocytic meningitis. The aim of this study was to provide data on the seasonal variation, anamnesis, symptoms, laboratory data and course of the disease in adults (≥ 16 years). METHODS: The medical records of 69 patients with confirmed LNB who attended the Department of Neurology, Lillebaelt Hospital, Vejle, Denmark, were analysed...

Lyme disease, infection with the tick-borne spirochete Borrelia burgdorferi, causes both specific and nonspecific symptoms. In untreated chronic infection, specific manifestations such as a relapsing large-joint oligoarthritis can persist for years, yet subside with appropriate antimicrobial therapy. Nervous system involvement occurs in 10%-15% of untreated patients and typically involves lymphocytic meningitis, cranial neuritis, and/or mononeuritis multiplex; in some rare cases, patients have parenchymal inflammation in the brain or spinal cord...
