1/39. Identification of candidate T-cell epitopes and molecular mimics in chronic Lyme disease.

    Elucidating the cellular immune response to infectious agents is a prerequisite for understanding disease pathogenesis and designing effective vaccines. In the identification of microbial T-cell epitopes, the availability of purified or recombinant bacterial proteins has been a chief limiting factor. In chronic infectious diseases such as lyme disease, immune-mediated damage may add to the effects of direct infection by means of molecular mimicry to tissue autoantigens. Here, we describe a new method to effectively identify both microbial epitopes and candidate autoantigens. The approach combines data acquisition by positional scanning peptide combinatorial libraries and biometric data analysis by generation of scoring matrices. In a patient with chronic neuroborreliosis, we show that this strategy leads to the identification of potentially relevant T-cell targets derived from both borrelia burgdorferi and the host. We also found that the antigen specificity of a single T-cell clone can be degenerate and yet the clone can preferentially recognize different peptides derived from the same organism, thus demonstrating that flexibility in T-cell recognition does not preclude specificity. This approach has potential applications in the identification of ligands in infectious diseases, tumors and autoimmune diseases. ( info)

2/39. lyme neuroborreliosis mimics stroke: a case report.

    lyme neuroborreliosis is diagnostically challenging because of its diverse manifestations. The well-documented neurologic spectrum includes lymphocytic meningitis, cranial neuropathy, and radiculoneuritis in the early disseminated stage; and peripheral neuropathy, chronic encephalomyelitis, and mild encephalopathy in the late persistent stage. This case report describes a 74-year-old man who developed progressive left hemiparesis and facial palsy. The patient was hospitalized to rule out a cerebral vascular accident. The diagnosis of Lyme borreliosis was established with serologic studies. The patient was treated with intravenous ceftriaxone and responded with rapid clinical and functional recovery. lyme neuroborreliosis presenting as hemiparesis has rarely been reported. Prompt diagnosis and treatment appear to facilitate symptomatic relief and prevent persistent neurologic deficits. ( info)

3/39. opsoclonus-myoclonus syndrome in a child with neuroborreliosis.

    Opsoclonus-myoclonus is a rare neurological syndrome affecting children and adults. In children it occurs as a parainfectious process or a paraneoplastic syndrome in association with neuroblastoma. Here we report it presenting as an unusual neurological manifestation of Lyme borreliosis. To our knowledge, this is the first report which describes recovery from this syndrome in a child. ( info)

4/39. Primarily chronic and cerebrovascular course of lyme neuroborreliosis: case reports and literature review.

    As part of an ongoing study aiming to define the clinical spectrum of neuroborreliosis in childhood, we have identified four patients with unusual clinical manifestations. Two patients suffered from a primarily chronic form of neuroborreliosis and displayed only non-specific symptoms. An 11 year old boy presented with long standing symptoms of severe weight loss and chronic headache, while the other patient had pre-existing mental and motor retardation and developed seizures and failure to thrive. Two further children who presented with acute hemiparesis as a result of cerebral ischaemic infarction had a cerebrovascular course of neuroborreliosis. One was a 15 year old girl; the other, a 5 year old boy, is to our knowledge the youngest patient described with this course of illness. Following adequate antibiotic treatment, all patients showed substantial improvement of their respective symptoms. Laboratory and magnetic resonance imaging findings as well as clinical course are discussed and the relevant literature is reviewed. ( info)

5/39. Chronic neuroborreliosis in infancy.

    lyme disease is a polymorphic and multisystemic disease caused by borrelia burgdorferi. Neurological manifestations are found in 10%-50% of cases. We present 2 cases followed for 5 and 6 years of chronic relapsing-remitting neuroborreliosis. diagnosis of neuroborreliosis in these cases was based on serum and cerebrospinal fluid findings. We discuss clinical, neurophysiological, laboratory and instrumental aspects regarding the difficulties of reaching a correct diagnosis. Further studies, especially in the field of immunology, should help identify the mechanisms responsible for the disease becoming chronic. With this knowledge, it may be possible to design immunological therapies for relapses, and to prevent the evolution of the disease. ( info)

6/39. chorea as a symptom of neuroborreliosis: a case study.

    borrelia burgdorferi (Bb) can cause a large number of neurological symptoms. Although extrapyramidal disturbances are rare (representing less than 2% of all neurological complications), diffuse choreic dyskinesias have been described during the course of mild encephalitis. The data published in the literature suggest that there are clinical and neurological analogies between neuroborreliosis and multiple sclerosis (MS). The presence of specific anti-Bb antibodies in cerebrospinal fluid is a discriminating factor that allows a diagnosis of neuroborreliosis to be made. We describe the case of a patient with lyme disease, characterised by widespread chorea and behavioural disturbances. Emphasis is placed on the atypical onset and evolution, the difficulties encountered in formulating a diagnosis, and the uncertainties concerning the pathophysiology and clinical/neuroradiological correlations of the disease.

7/39. Lyme borreliosis mimicking central nervous system malignancy: the diagnostic pitfall of cerebrospinal fluid cytology.

    We report two children with acute loss of neurological functions and signs of an increased intracranial pressure. Imaging techniques ruled out space occupying lesions, whereas CSF cytology indicated CNS involvement of a non-Hodgkin lymphoma in the form of abnormal lymphocytic pleocytosis with malignancy criteria fulfilling lymphoid cells. CSF protein electrophoresis and borrelia burgdorferi serology revealed neuroborreliosis which was successfully treated with antibiotic therapy. The malignancy mimicking cytology is based on a blastoid transformation of B- and t-lymphocytes due to the antigenic stimulus of B. burgdorferi infection. Lymphoid cells in the CSF of a patient with acute or chronic neurological symptoms raise the differential diagnosis of inflammatory etiology versus CNS lymphoma. Monomorphism and higher quantity of the lymphoid cells point to CNS lymphoma. A lower quantity and polyclonal pattern of lymphoid cells associated with an elevated protein fraction caused by intrathecal immunoglobulin synthesis suggest an inflammatory etiology. ( info)

8/39. Spontaneous brain hemorrhage associated with lyme neuroborreliosis.

    We present the case of a patient with late neuroborreliosis and a spontaneous temporal lobe hemorrhage. Although ischemic stroke and subarachnoid hemorrhage have been reported in association with lyme disease, intraparenchymal brain hemorrhage has not been previously described in the course of this disease. The patient is a 48-year old male with a progressive spastic paraparesis of months' duration who presented acute headache, confusion, severe left hemiparesis with sensory deficit and homonymous hemianopsia. A cranial computed tomography scan showed an extensive right temporal lobe hemorrhage with subarachnoid invasion. brain angiographic and angio-magnetic resonance imaging studies excluded hemorrhage-predisposing vascular abnormalities. cerebrospinal fluid (CSF) studies disclosed mononuclear pleocytosis with elevated protein levels. Both serum and CSF anti-Borrelia titers were significantly increased, and serum Western Blot showed bands to protein 34 (ops B), 57, 59 and 62. The patient was treated with ceftriaxone for 4 weeks, with a favorable outcome. It is suspected that cause of the hemorrhage was parenchymatous Lyme-associated vascular damage and/or microaneurysmatic rupture. ( info)

9/39. dysarthria as the isolated clinical symptom of borreliosis--a case report.

    This report presents a case of dysarthria due to hypoglossal nerve mono-neuropathy as the only consequence of neuroborreliosis. The 65-year-old man with a seven-months history of articulation disturbances was examined. The speech of the patient was slow and laboured. A slight weakness of the muscles of the tongue (left-side) was observed. The patient suffered from meningitis due to borrelia burgdorferi infection in 1999 and initially underwent a successful antibiotic treatment. Detailed radiological investigation and psychological tests were performed and co-existing neurological diseases were excluded. To describe profile of speech abnormalities the dysarthria scale was designed based on S. J. Robertson dysarthria Profile. There were a few disturbances found in self-assessment of speech, intelligibility, articulation, and prosody but especially in the morphology of the articulation muscles, diadochokinesis, the reflexes (in the mouth, larynx and pharynx). Needle EMG examination confirmed the diagnosis of mono-neuropathy of left hypoglossal nerve. The study confirms the fact that neuroborreliosis may evoke chronic consequences. ( info)

10/39. optic nerve lesion following neuroborreliosis: a case report.

    PURPOSE: Neuroborreliosis may cause various neuro-ophthalmological complications. We describe a case with a bilateral optic neuropathy. CASE REPORT: A 58-year-old female developed facial paresis six weeks after an insect bite. One week later she developed bilateral optic disc swelling with haemorrhages and nerve fibre bundle defects in the lower visual field of the left eye. In CSF and serum, raised IgM and IgG titres to borrelia burgdorferi were found. Systemic antibiotic treatment led to improvement of the vision and facial paresis, but not all visual field defects resolved, probably due to ischemic lesions of the optic disc. DISCUSSION/CONCLUSIONS: In optic nerve lesions due to neuroborreliosis it is difficult to distinguish between inflammatory and ischemic lesions. This patient demonstrated features of an ischemic optic nerve lesion. ( info)
