Lyme neuroborreliosis in children: Report of nine cases and a review of the literature

Case presentation and management of Lyme disease patients: a 9-year retrospective analysis in France

Introduction

Lyme borreliosis (LB) is the most common vector disease in temperate countries of the northern hemisphere. It is caused by Borrelia burgdorferi sensu lato complex.

Methods

To study the case presentation of LB in France, we contacted about 700 physicians every year between 2003 and 2011. An anonymous questionnaire was established allowing the collection of 3,509 cases. The information collected was imported or directly entered into databases and allowed identifying variables that were validated in a multiple correspondence analysis (MCA).

Results

Sixty percent of the cases were confirmed, 10% were probable, 13.5% doubtful, 10.2% asymptomatic seropositive and 6.3% were negative. The clinical manifestations reported were cutaneous (63%), neurological (26%), articular (7%), ocular (1.9%) and cardiac (1.3%). Almost all patients were treated. When focusing more particularly on confirmed cases, our studies confirm that children have a distinct clinical presentation from adults. There is a gender effect on clinical presentation, with females presenting more often with erythema migrans or acrodermatitis chronica atrophicans than males, while males present more often with neurological signs or arthritis than females.

Discussion

This is the first time that a comprehensive study of suspected Lyme borreliosis cases has been conducted over several years in France. Although we were not able to follow the clinical course of patients after treatment, these results suggest the interest of refining the questionnaire and of following up a cohort of patients over a sufficiently long period to obtain more information on their fate according to different parameters.

Lyme Neuroborreliosis in Children

Lyme neuroborreliosis (LNB) is an infectious disease, developing after a tick bite and the dissemination of Borrelia burgdorferi sensu lato spirochetes reach the nervous system. The infection occurs in children and adults but with different clinical courses. Adults complain of radicular pain and paresis, while among the pediatric population, the most common manifestations of LNB are facial nerve palsy and/or subacute meningitis. Moreover, atypical symptoms, such as fatigue, loss of appetite, or mood changes, may also occur. The awareness of the various clinical features existence presented by children with LNB suspicion remains to be of the greatest importance to diagnose and manage the disease.

Posttreatment Lyme Disease Syndrome-What It Might Be and What It Is Not

Lyme disease is a multisystem disease caused by Borrelia burgdorferi infection and accounts for well-defined manifestations, appearing either at an early or late stage. Appropriate antibiotic therapy generally leads to a favorable outcome. Still, unspecific persisting symptoms such as fatigue, myalgia, arthralgia or cognitive dysfunction are reported by several patients months to years after adequate treatment. Their underlying pathophysiologic mechanism is unclear. However, there is no evidence for microbiological persistence in these cases and attempts to resolve the symptoms by repeated or prolonged antibiotic treatment have not been convincingly successful, but they may rather be harmful. To narrow down the controversially handled entity of posttreatment Lyme disease syndrome (PTLDS) and to avoid overdiagnosis and overtreatment, case definitions have been proposed, acknowledging PTLDS as a complex of nonspecific, subjective symptoms, which are neither caused by ongoing infection nor by any other identifiable disease. PTLDS is mainly a diagnosis of exclusion and requires careful evaluation of differential diagnosis followed by counseling about optimal management in light of missing specific therapeutic options.

Lyme disease: diagnosis and treatment

PURPOSE OF REVIEW

Lyme disease is an important, vector-borne infection found throughout the temperate Northern hemisphere. The disease causes rash, acute systemic illness, and in some untreated patients, inflammatory arthritis. This review examines the emergence, clinical features and management of early Lyme disease and Lyme arthritis.

RECENT FINDINGS

There has been continuing progress in characterizing the clinical manifestations, diagnostic testing and treatment of Lyme disease. Almost all patients with early Lyme disease can be cured with antibiotic treatment. In most cases, Lyme arthritis also responds to antibiotics, but some patients require additional treatment approaches.

SUMMARY

The diagnosis of Lyme disease is based on clinical manifestations and adjunctive laboratory testing. For the rheumatologist, Lyme arthritis should be recognized by a pattern of attacks of asymmetric, oligo-arthritis, recognizable by clinical manifestations in the same way that other rheumatic diseases, such as gout or rheumatoid arthritis, are diagnosed.

Comparison of Neuroborreliosis Between Children and Adults

BACKGROUND

Lyme neuroborreliosis (NB) is a tick-borne infectious disorder of the nervous system caused by Borrelia burgdorferi spirochetes. There are not many data available regarding the differences in the course of NB in children and adults. The aim of our study was to compare the clinical course of NB between children and adults.

METHODS

Retrospective analysis of medical documentation of 181 patients with NB was performed. The patients were divided into 2 groups: Group I: 57 children with NB; Group II: 124 adults with NB. Medical data, such as patients' age, sex, place of living (residence), time from a tick bite, subjective complaints, general examination results, laboratory parameters and treatment were analyzed.

RESULTS

In children, the most common symptoms were headache (89.5%), neck stiffness (64.9%) and nausea and vomiting (56.1%). In adults, the most common symptoms were headache (77.4%), facial nerve palsy (59.7%), neck stiffness (59.7%), vertigo (41.9%) and lumbosacral region pain (37.1%). Bannwarth's syndrome was observed in 10.5% of children and 36.3% of adults. In cerebrospinal fluid (CSF) in children, the pleocytosis at admission was higher than in adults, but protein concentration was significantly lower. There were no differences in percentage of mononuclear cells in CSF smear between the groups. In CSF examination after treatment, a decrease in pleocytosis and protein concentration was observed in both groups. Analysis of effectiveness of treatment mostly with third generation cephalosporins (defined as complete recovery) between the groups, calculated by the Kaplan-Meier method and compared with the use of the log-rank test, showed no significant differences between children and adults (log-rank P = 0.619).

CONCLUSIONS

In children, NB more frequently presented as meningitis, and in adults in the form of Bannwarth's syndrome. CSF pleocytosis in children with NB was higher than in adults, while the protein concentration in children was lower. Outcomes in children and adults were favorable and did not differ after standard NB treatment.
