Clinical manifestations of neuroborreliosis in children – review of literature

Introduction: The most common tick-borne disease caused by the spirochete Borrelia burgdorferi is Lyme disease. It is characterized by a variety of disorders: dermatological, rheumatological, cardiological and neurological. Neuroborreliosis is defined as an involvement of the nervous system, and it is the second most common form of infection in children (10-15% of those infected). The aim of the study: To review the available materials and presentation of the current state of knowledge on the various manifestations of neuroborreliosis in children. Material and method: Databases such as PubMed and Google Scholar were searched. Literature was searched using the keywords: Lyme disease, neuroborreliosis, borreliosis, facial nerve paralysis, and pediatric population. The materials obtained in this way were analyzed in terms of compliance with the subject of the work. Results: Typical clinical manifestations of neuroborreliosis in children are facial nerve palsy and meningitis. Neuroborreliosis is the cause of 50% of all cases of bilateral facial nerve palsy in children. Multiple cranial and peripheral neuritis, myelitis, cerebral vasculitis and, consequently, the formation of intracranial aneurysms are less common manifestations of infection. Conclusions: The symptoms of neuroborreliosis are non-specific. This makes it difficult to make an accurate diagnosis. Even if no information on tick bite or erythema migrans has been obtained from the clinical history, neuroborreliosis should be considered in the differential diagnosis, especially in Lyme-endemic areas

The Emerging Role of Microbial Biofilm in Lyme Neuroborreliosis

Lyme borreliosis (LB) is the most common tick-borne disease caused by the spirochete Borrelia burgdorferi in North America and Borrelia afzelii or Borrelia garinii in Europe and Asia, respectively. The infection affects multiple organ systems, including the skin, joints, and the nervous system. Lyme neuroborreliosis (LNB) is the most dangerous manifestation of Lyme disease, occurring in 10-15% of infected individuals. During the course of the infection, bacteria migrate through the host tissues altering the coagulation and fibrinolysis pathways and the immune response, reaching the central nervous system (CNS) within 2 weeks after the bite of an infected tick. The early treatment with oral antimicrobials is effective in the majority of patients with LNB. Nevertheless, persistent forms of LNB are relatively common, despite targeted antibiotic therapy. It has been observed that the antibiotic resistance and the reoccurrence of Lyme disease are associated with biofilm-like aggregates in B. burgdorferi, B. afzelii, and B. garinii, both in vitro and in vivo, allowing Borrelia spp. to resist to adverse environmental conditions. Indeed, the increased tolerance to antibiotics described in the persisting forms of Borrelia spp., is strongly reminiscent of biofilm growing bacteria, suggesting a possible role of biofilm aggregates in the development of the different manifestations of Lyme disease including LNB

Abdominal pain as first manifestation of lyme neuroborreliosis in children, case report and review of literature

Background: Lyme neuroborreliosis can cause a variety of neurological manifestations. European children usually present facial nerve palsy, other cranial nerve palsies and aseptic meningitis. Case presentation: We hereby report a case of Lyme neuroborreliosis in a 9-year-old boy with abdominal pain as first symptom and subsequent onset of attention deficit and ataxia. Diagnosis was made by detection of specific antibody in both serum and cerebrospinal fluid with neuro-radiological images suggestive for this infectious disease. A 12-months follow-up was performed during which no relevant neurological sequelae were revealed. Conclusion: This case report shows that abdominal radiculitis, although extremely rare, could be the first manifestation of early Lyme neuroborreliosis in pediatric patients. Pediatricians must consider Lyme disease in the differential diagnosis of abdominal pain of unknown origin in children, especially in countries where the infection is endemic

Acute transverse myelitis in Lyme neuroborreliosis

Introduction: Acute transverse myelitis (ATM) is a rare disorder (1-8 new cases per million of population per year), with 20% of all cases occurring in patients younger than 18years of age. Diagnosis requires clinical symptoms and evidence of inflammation within the spinal cord (cerebrospinal fluid and/or magnetic resonance imaging). ATM due to neuroborreliosis typically presents with impressive clinical manifestations. Case presentation: Here we present a case of Lyme neuroborreliosis-associated ATM with severe MRI and CSF findings, but surprisingly few clinical manifestations and late conversion of the immunoglobulin G CSF/blood index of Borrelia burgdorferi sensu lato. Conclusion: Clinical symptoms and signs of neuroborrelial ATM may be minimal, even in cases with severe involvement of the spine, as shown by imaging studies. The CSF/blood index can be negative in the early stages and does not exclude Lyme neuroborreliosis; if there is strong clinical suspicion of Lyme neuroborreliosis, appropriate treatment should be started and the CSF/blood index repeated to confirm the diagnosi

A rare cause of peripheral facial paralysis in childhood in our country: lyme disease

Lyme disease is a zoonosis caused by Spirochetes called Borrelia burgdorferi, involving several areas, such as the skin, heart and central nervous system. In this case report, we present a 10-year-old male who had complaints of fever, extensive oral aphthae, perioral dried sores, rash, blurred vision and peripheral facial paralysis, and was diagnosed with Lyme disease. In this report, we want to emphasize that Lyme disease should be kept in mind for differential diagnosis in patients with fever and peripheral facial paralysis

Pediatric stroke related to Lyme neuroborreliosis: Data from the Swiss NeuroPaediatric Stroke Registry and literature review.

Cerebrovascular complications of Lyme neuroborreliosis (LNB) are poorly documented in the paediatric population. 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. 4 children out of 229 children with arterial ischemic childhood stroke and serologically confirmed LNB were identified in the SNPSR giving a global incidence of 1.7%. Median age was 9.9 years. A prior history of tick bites or erythema migrans (EM) was reported in two cases. Clinical presenting signs were suggestive of acute cerebellar/brainstem dysfunction. On imaging, three children demonstrated a stroke in the distribution of the posterior inferior cerebellar artery. The remaining fourth child had a "stroke-like" picture with scattered white matter lesions and a multifocal vasculitis with prominent basilar artery involvement. Lymphocytic pleocytosis as well as intrathecal synthesis of Borrelia burgdorferi antibodies were typical biological features. Acute intravenous third generation cephalosporins proved to be effective with rapid improvement in all patients. No child had recurrent stroke. Data from the literature concerning eight patients gave similar results, with prominent posterior circulation stroke, multifocal vasculitis and abnormal CSF as distinctive features. Lyme Neuroborreliosis accounts for a small proportion of paediatric stroke even in an endemic country. The strong predilection towards posterior cerebral circulation with clinical occurrence of brainstem signs associated with meningeal symptoms and CSF lymphocytosis are suggestive features that should rapidly point to the diagnosis. This can be confirmed by appropriate serological testing in the serum and CSF. Clinicians must be aware of this rare neurological complication of Lyme disease that demands specific antibiotic treatment
