Neuroborreliosis may be caused by different species of Borrelia burgdorferi (BB) and the clinical presentation of neuroborreliosis in children may differ between geographical areas due to occurrence of different BB genospecies. The aim of this study was to evaluate the clinical characteristics in children with neuroborreliosis in an endemic area of Scandinavia. During 1996-2006, children with suspected neuroborreliosis referred to Stavanger University Hospital were investigated by a standard procedure including a lumbar puncture. A total of 143 children were diagnosed with neuroborreliosis, and all cases were diagnosed from April to December. The most common clinical presentations were symptoms of mild meningitis (75%) and/or facial nerve palsy (69%). Radicular pain was present in only 10 children. In all but 5 children, laboratory signs of meningitis were present. Erythema migrans preceded the neurological symptoms in only 27% of the children. In conclusion, we have found that in an endemic area of northern Europe, meningitis is present in the majority of children with neuroborreliosis, and that symptoms of a mild meningitis or facial nerve palsy are the most common presentations.
Acute facial nerve palsy in children may be caused by infection by Borrelia burgdorferi, but the incidence of facial nerve palsy and the proportion of facial nerve palsy caused by Lyme borreliosis may vary considerably between areas. Furthermore, it is not well known how often facial nerve palsy caused by Lyme borreliosis is associated with meningitis. In this population-based study, children admitted for acute facial nerve palsy to Stavanger University Hospital during 9 y from 1996 to 2004 were investigated by a standard protocol including a lumbar puncture. A total of 115 children with facial nerve palsy were included, giving an annual incidence of 21 per 100,000 children. 75 (65%) of these were diagnosed as Lyme borreliosis, with all cases occurring from May to November. Lymphocytic meningitis was present in all but 1 of the children with facial nerve palsy caused by Lyme borreliosis where a lumbar puncture was performed (n = 73). In this endemic area for Borrelia burgdorferi, acute facial nerve palsy in children was common. The majority of cases were caused by Lyme borreliosis, and nearly all of these were associated with lymphocytic meningitis.
The current diagnostic marker of Lyme neuroborreliosis (LNB), the antibody index (AI) in the cerebrospinal fluid (CSF), has insufficient sensitivity in the early phase of LNB. We aimed to elucidate the diagnostic value of PCR for in CSF from children with symptoms suggestive of LNB and to explore genotypes associated with LNB in children. Children were prospectively included in predefined groups with a high or low likelihood of LNB based on diagnostic guidelines (LNB symptoms, CSF pleocytosis, and antibodies) or the detection of other causative agents. CSF samples were analyzed by two -specific real-time PCR assays and, if DNA was detected, were further analyzed by five singleplex real-time PCR assays for genotype determination. For children diagnosed as LNB patients (58 confirmed and 18 probable) ( = 76) or non-LNB controls ( = 28), the sensitivity and specificity of PCR for in CSF were 46% and 100%, respectively. DNA was detected in 26/58 (45%) children with AI-positive LNB and in 7/12 (58%) children with AI-negative LNB and symptoms of short duration. Among 36 children with detectable DNA, genotyping indicated ( = 27) and non- ( = 1) genotypes, while 8 samples remained untyped. Children with LNB caused by did not have a distinct clinical picture. The rate of detection of DNA in the CSF of children with LNB was higher than that reported previously. PCR for could be a useful supplemental diagnostic tool in unconfirmed LNB cases with symptoms of short duration. was the predominant genotype in children with LNB.
LM was diagnosed in two-thirds of children with infectious meningitis in this LB endemic area. Distinct clinical characteristics distinguished the majority of children with LM from children with non-Lyme aseptic meningitis and bacterial meningitis.
The occurrence of IgM and IgG antibodies against Borrelia burgdoferi in serum and cerebrospinal fluid (CSF) and intrathecal synthesis of antibodies (antibody index) were studied in relation to clinical presentation and the duration of symptoms before diagnosis in 146 children diagnosed with neuroborreliosis. Lymphocytic meningitis was demonstrated in 141 of these children. Levels of white blood cells (WBC) and protein in CSF correlated significantly to numbers of d with symptoms. Children were divided into 3 clinical groups: A (n = 37): only cranial neuropathy; B (n = 68): both cranial neuropathy and other neurological symptoms; C (n = 41): neurological symptoms without cranial neuropathy. Levels of WBC and protein in CSF as well as the proportion of children with antibodies in serum and CSF were generally lowest in group A, intermediate in group B and highest in group C. The proportion of children with antibodies in serum and CSF and a positive antibody index was also related to duration of symptoms; the antibody index was present in 51% of children with symptoms < or = 7 d, and in 80% of children with symptoms > 7 d (p<0.01). The clinical presentation and duration of symptoms must be considered when interpreting laboratory data in children with suspected neuroborreliosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
