[Bilateral facial palsy: an atypical presentation of Lyme disease (a case report)]. / Paralysie faciale bilatérale : une présentation atypique d'une maladie de Lyme (cas clinique).

Lyme neuroborreliosis is a rare zoonosis which can be difficult to diagnose, in particular in low endemic areas. We here report the case of a 35-year-old man presenting with disabling back pain preceded by facial monoplegia, which was wrongly treated as Bell's palsy (paralysis a frigore) and then as post-traumatic lumbosciatica. The onset of facial diplegia allowed for a definitive diagnosis. The patient was treated with ceftriaxone and symptoms gradually improved.

Antibody responses to immunoevasion proteins BBK32 and OspE constitute part of the serological footprint in neuroborreliosis but are insufficient to prevent the disease.

Lyme borreliosis, caused by Borrelia burgdorferi sensu lato, is the most common tickborne disease. Its neuronal form, neuroborreliosis, comprises 3 to 38% of borreliosis cases in Europe. Borrelia outer surface proteins and virulence factors, OspE and BBK32, have been previously reported to help cause infection by promoting attachment to human host epithelial cells and evading complement attack. We assessed the serological responses to BBK32 and OspE in 19 individuals diagnosed with neuroborreliosis to see whether antibodies that could both target the bacteria and neutralize the virulence mechanisms on the microbial surface emerge. Results evaluate levels of total protein, IgG and the chemokine CXCL13, a determinant for B-cell recruitment during neuroinflammation, in patients' cerebrospinal fluid samples. Antibody levels against BBK32 and OspE correlated with those against VlsE, a well-characterized diagnostic serological marker of the disease. A dual serological profile of the patients was observed. K-means clustering split the cohort into two discrete groups presenting distinct serological and CNS responses. One group contained young patients with low levels of anti-BBK32 and OspE antibodies. The other group showed stronger responses, possibly following prolonged infections or reinfections. Additionally, we assessed anti-ganglioside antibodies that could cause autoimmunity or complement dysregulation but observed that they did not correlate with neuroborreliosis in our patient cohort. The dual nature of antibody responses against the virulence factors BBK32 and OspE in neuroborreliosis patients may suggest the necessity of repeated exposures for efficient immune responses. Better protection could be achieved if the virulence factors were formulated into vaccines.

Diagnostic patterns of serum inflammatory protein markers in children with Lyme neuroborreliosis.

Definite diagnosis of Lyme neuroborreliosis (LNB) requires investigation of serum and cerebrospinal fluid (CSF). Thus, lumbar puncture is necessary, and requires administration of sedating drugs in children. This study aimed to investigate if a pattern of different inflammatory biomarkers in serum could contribute to the selection of children for lumbar puncture in suspected LNB. Patients were included from a cohort of children who was previously investigated for LNB including serum and CSF sampling during the years 2010-2014. The multiplex proximity extension assay (PEA) inflammation panel Target 96 (Olink Bioscience, Uppsala, Sweden) was used to examine 92 biomarkers in serum. Based on the presence of CSF pleocytosis and Borrelia-specific antibodies, patients were divided into a definite LNB group (n=61) and a non-LNB control group (n=58). Following PEA and statistical analysis with multivariate logistic regression, five biomarkers remained significant (p < 0.001), which were included in a calculation of protein index. The index biomarkers were CST5, IL-15RA, CXCL10, DNER and CX3CL1. A receiver operating characteristic curve was constructed from the index, which showed an 80 % sensitivity and 81 % specificity. Area under the curve was 0.889. We offer evidence that, with further refinements, patterns of serum biomarkers might help identify those children more or less likely to have LNB, perhaps ultimately decreasing the need for lumbar punctures.

Characteristics of patients consulted for suspected Lyme neuroborreliosis in an endemic area.

INTRODUCTION: Some patients with unexplained neurological symptoms sought care for presumed Lyme neuroborreliosis (LNB). We aimed to compare patients' characteristics with and without LNB. MATERIAL AND METHODS: All patients consulting for LNB suspicion and having a lumbar puncture between 2014 and 2020 in a high endemic area of Lyme borreliosis were included in the study. RESULTS: One hundred fifty-five patients were included. Forty-five patients (29 %) had LNB (mean age: 57.6 years, 28.9 % of women) including 17 with isolated intrathecal synthesis. One hundred and ten patients had no LNB (mainly neurological (29 %) and rheumatological diseases (19 %)). Non-neurological symptoms were similar in patients with LNB and patients with no LNB (asthenia, 31 % vs. 46 %, p = 0.14, arthralgia 20 % vs. 31 %, p = 0.14) with the exception of myalgia, which was less frequent in patients with LNB (4.4 % vs. 19.1 % p = 0.02). In multivariable analysis, factors associated with LNB were presence of facial nerve palsy (OR = 5.7), radiculopathy (OR = 11.3), positive Lyme serology (OR = 5.4) and duration of symptoms less than 3 months (OR = 4.48). Patients with isolated intrathecal synthesis had a longer duration of symptoms (3 vs 1 months) than patients with pleocytosis. Asthenia (5.9 % vs. 32.1 %), headaches (0 % vs. 39.3 %) neuropathic pain (17.6 % vs. 50 %) and facial palsy (11.8 % vs. 39.3 %) were less frequent in patients with isolated intrathecal synthesis than patients with pleocytosis. The presence of isolated subjective neurological symptoms (paresthesia, memory disorders, insomnia, irritability, asthenia, headaches) was reported in 7/17 (41 %) of patients with isolated intrathecal synthesis, 2/28 (7.1 %) in patients with pleocytosis and 75/110 (68 %) in patients without LNB (p < 0.001). CONCLUSION: More than one quarter of patients consulted for suspected LNB had non-neurologic symptoms, whether or not they have a LNB. Concerning patients with isolated intrathecal synthesis, the question of presence of sequelae with a spontaneously cured disease or an active Lyme borreliosis requiring antibiotic remain.

Spectrum of MRI findings in central nervous system affection in Lyme neuroborreliosis.

Affections of the central nervous system (CNS) rarely occur in Lyme neuroborreliosis (LNB). CNS manifestations can have residual neurological symptoms despite antibiotic treatment. We explored the spectrum of CNS affections in patients with LNB in a tertiary care center in a region endemic for Lyme borreliosis. We retrospectively included patients treated at a tertiary care center from January 2020-December 2021 fulfilling the case criteria for LNB as stated in the current German guideline on LNB. Clinical data, cerebrospinal fluid (CSF) findings and MRI imaging were collected. We included 35 patients with LNB, 24 with early manifestations and 11 with CNS-LNB. CNS-LNB patients had encephalomyelitis (n = 6) or cerebral vasculitis (n = 5). Patients with early LNB and CNS-LNB differed regarding albumin CSF/serum quotient and total protein in CSF. Duration from onset of symptoms until diagnosis was statistically significantly longer in patients with encephalomyelitis. MRI findings were heterogeneous and showed longitudinal extensive myelitis, perimedullar leptomeningeal enhancement, pontomesencephalic lesions or cerebral vasculitis. CNS-LNB can present with a variety of clinical syndromes and MRI changes. No clear pattern of MRI findings in CNS-LNB could be identified. The role of MRI consists in ruling out other causes of neurological symptoms.

Optic nerve involvement in patients with Lyme neuroborreliosis: an electrophysiological study.

PURPOSE: The aim of this neurophysiological study was to retrospectively analyze visual evoked potentials (VEPs) acquired during an examination for diagnosing optic nerve involvement in patients with Lyme neuroborreliosis (LNB). Attention was focused on LNB patients with peripheral facial palsy (PFP) and optic nerve involvement. METHODS: A total of 241 Czech patients were classified as having probable/definite LNB (193/48); of these, 57 were younger than 40 years, with a median age of 26.3 years, and 184 were older than 40 years, with a median age of 58.8 years. All patients underwent pattern-reversal (PVEP) and motion-onset (MVEP) VEP examinations. RESULTS: Abnormal VEP results were observed in 150/241 patients and were noted more often in patients over 40 years (p = 0.008). Muscle/joint problems and paresthesia were observed to be significantly more common in patients older than 40 years (p = 0.002, p = 0.030), in contrast to headache and decreased visual acuity, which were seen more often in patients younger than 40 years (p = 0.001, p = 0.033). Peripheral facial palsy was diagnosed in 26/241 LNB patients. Among patients with PFP, VEP peak times above the laboratory limit was observed in 22 (84.6%) individuals. Monitoring of patients with PFP and pathological VEP showed that the adjustment of visual system function occurred in half of the patients in one to more years, in contrast to faster recovery from peripheral facial palsy within months in most patients. CONCLUSION: In LNB patients, VEP helps to increase sensitivity of an early diagnostic process.

Neuroborreliosis interpreted as multiple sclerosis by MRI.

Lyme neuroborreliosis (LNB) is the most prevalent nervous system bacterial infection in Denmark. In a young man with LNB, brain MRI and cerebrospinal fluid (CSF) demonstrated findings compatible with multiple sclerosis. This case report underlines the requirement for testing for intrathecal Borrelia antibody production when the number of cells in the CSF is low or even normal. It also demonstrates the unchanged diagnostic delay of NBL observed during the last 20 years.

Cranial nerve involvement, visual complications and headache syndromes in Lyme disease.

PURPOSE OF REVIEW: To provide a summary of the visual manifestations and cranial neuropathies seen in Lyme disease. RECENT FINDINGS: Lyme facial palsy remains the most common manifestation of Lyme neuroborreliosis. Recent investigations show likely evidence of vagal involvement in Lyme disease. SUMMARY: The literature on Lyme neuroborreliosis continues to evolve. Lyme disease can affect nearly any cranial nerve in addition to causing various headache syndromes. The most common manifestation is Lyme disease facial palsy, occurring in up to 5-10% of patients with documented Lyme disease. Headache syndromes are common in the context of facial palsy but can occur in isolation, and more specific headache syndromes including trigeminal and geniculate neuralgias can occur rarely. Signs and symptoms indicative of vestibulocochlear nerve involvement are relatively common, although it could be that these represent other vestibular involvement rather than a specific cranial neuropathy. Optic neuritis is a controversial entity within Lyme disease and is likely overdiagnosed, but convincing cases do exist. Physicians who see any cranial neuropathy, including optic neuritis, in an endemic area can consider Lyme disease as a possible cause.

Atypical Acute Neuroborreliosis With Leg Paresis and Constipation.

BACKGROUND/AIM: An 80-year-old male patient had complained of proximal paresis of the left leg, pain and sensory disturbances in the left abdomen, exanthema in the left lower abdomen, coprostasis, and severe abdominal pain, as well as a progressive deterioration of his general condition for weeks. The patient had already presented to three other medical centers. Colonoscopy and computed tomography of the abdomen could not explain the pronounced symptomatology. In addition, there was acute elevator paresis of the left leg and severe pruritic rash on both sides of the trunk. CASE REPORT: At the Israelitisches Krankenhaus Hamburg (IKH), laboratory parameters of urine, stool, and blood, ultrasound, electrocardiogram, and transthoracic echocardiography diagnosis showed no abnormalities. Esophago-gastro-duodenoscopy revealed patchy erythema and moderately severe chronic low-activity Helicobacter-positive gastritis. Colonoscopically, two polyps were ablated. A neurological examination with magnetic resonance imaging and electroneurography also showed normal findings. Evidence of autoimmune or rheumatoid disease was also absent. Finally, analysis of the cerebrospinal fluid revealed a lympho-granulocytic cell count (32/3 lymphocytes, 21/3 granulocytes) and an elevated Borrelia-specific IgG index (Ai) of 20.82. This finding was confirmed by a complementary serological diagnosis, in which Borrelia-specific IgM and IgG antibodies were detected. In sum, Bannwart's syndrome was assumed to be the cause of the neurological symptoms. The 21-day borreliosis therapy included doxycycline administration and analgesia with novaminsulfone and pregabalin as needed. CONCLUSION: A complex symptomatology of leg paresis, lower abdominal pain and sensory disturbances, exanthema, and coprostasis in combination with a long-lasting poor general condition were found to be the consequences of atypical neuroborreliosis.

Isolated Intracranial Hypertension as a Presentation of Pediatric Lyme Borreliosis: A Case Report and Literature Review.

BACKGROUND: It is extremely rare for Lyme borreliosis to present solely with features of increased intracranial pressure. The treatment of pediatric Lyme neuroborreliosis with oral versus intravenous antibiotics remains controversial. METHODS: Case report and literature review. RESULTS: A 13-year-old male presented with five days of binocular diplopia, several weeks of headache, and a history of multiple tick bites six weeks prior. His examination showed a left eye abduction deficit and bilateral optic disc edema. Magnetic resonance imaging (MRI) of the brain with contrast showed tortuosity of the optic nerves, prominence of the optic nerve sheaths, and enhancement of the left fifth and bilateral sixth cranial nerves. Lumbar puncture showed an elevated opening pressure and a lymphocytic pleocytosis. Lyme IgM and IgG antibodies were positive in the serum and cerebrospinal fluid. The patient was treated with intravenous ceftriaxone for two days empirically followed by doxycycline by mouth for 19 days. Symptoms began improving after 48 hours. The strabismus resolved after two weeks, and the papilledema improved slowly with complete resolution at six months. CONCLUSIONS: Lyme neuroborreliosis can present as isolated intracranial hypertension in the pediatric population; it can be differentiated from idiopathic intracranial hypertension on MRI, and lumbar puncture and can be confirmed with serum antibody testing. Oral doxycycline can be considered for Lyme neuroborreliosis in children.

Incidence of Lyme Borreliosis in Germany: A retrospective observational healthcare claims study.

Lyme borreliosis (LB) is the most common tick-borne disease in Germany. Although the incidence of LB in Germany has been assessed in several studies, those studies either used data from statutory surveillance, which frequently underreport cases, or data from health claims databases, which may overestimate cases due to non-specific LB case definitions. Here, using a more specific case definition, we describe the incidence of medically-attended LB by disease manifestation, age group, and federal state for the period 2015-2019. Both inpatient and outpatient cases were analyzed from a claims database. To be eligible for inclusion, patients were required to have an LB specific ICD-10 GM diagnosis code plus an antibiotic prescription, and for disseminated manifestations, a laboratory test order additionally. LB cases were classified as erythema migrans (EM), or disseminated disease including Lyme arthritis (LA), Lyme neuroborreliosis (LNB), and all other disease manifestations (OTH). Between 2015 and 2019, the incidence of medically-attended LB cases ranged from 195.7/100,000 population per year (95% confidence interval [CI], 191.0 - 200.5) to 254.5/100,000 population per year (95% CI, 249.0 - 260.0) per year. The majority of cases (92.2%) were EM, while 2.8% presented as LA, 3.8% as LNB, and 1.2% as OTH. For both EM and disseminated disease, the incidence peaked in children aged 5-9 years and in older adults. By federal state, the incidence of medically-attended EM ranged from 74.4/100,000 population per year (95% CI, 71.9 - 77.0) per year in Hamburg, to 394.1/100,000 population per year (95% CI, 370.7 - 417.6) per year in Saxony, whereas for medically-attended disseminated disease, the highest incidence was in Thuringia, Saxony, and Bavaria (range: 22.0 [95% CI, 19.9 - 24.0] to 35.7 [95% CI, 34.7 - 36.7] per 100,000 population per year). This study comprehensively estimated the incidence of all manifestations of medically-attended LB and showed a high incidence of LB throughout Germany. Results from the study support performing epidemiological studies in all federal states to measure the burden of LB and to invest in public health interventions for prevention.

Serum neurofilament light chain associates with symptom burden in Lyme neuroborreliosis patients: a longitudinal cohort study from Norway.

OBJECTIVES: Serum neurofilament light chain (sNfL), an indicator of neuronal damage, is increasingly recognized as a potential biomarker for disease activity in neurodegenerative disorders. In this study, we wanted to investigate sNfL as a prognostic marker in a large, well-defined population of 90 patients with Lyme neuroborreliosis (LNB). In addition, we sought to explore associations between symptoms and sNfL levels during the acute phase of LNB. MATERIALS AND METHODS: Patients diagnosed with definite or possible LNB were recruited from a double-blinded, placebo-controlled, multi-center trial, in which the participants were randomly assigned to 2 or 6 weeks of oral doxycycline treatment. The sNfL levels were measured using a single molecule array assay at both diagnosis and 6-month follow-up, and analysed against clinical parameters, variations in symptom burden and long-term complaints as assessed by a composite clinical score. RESULTS: At the time of diagnosis, approximately 60% of the patients had elevated sNfL levels adjusted for age. Notably, mean sNfL levels were significantly higher at diagnosis (52 pg/ml) compared to 6 months after treatment (12 pg/ml, p < 0.001), when sNfL levels had normalized in the majority of patients. Patients with objective signs of spinal radiculitis had significantly higher baseline sNfL levels compared to patients without spinal radiculitis (p = 0.033). CONCLUSION: Our findings suggest that sNfL can serve as a biomarker for peripheral nerve tissue involvement in the acute phase of LNB. As found in an earlier study, we confirm normalization of sNfL levels in blood after treatment. We found no prognostic value of acute-phase sNfL levels on patient outcome.

Paretic complications of tick-borne encephalitis and Lyme neuroborreliosis in the Czech Republic: Characteristics and clinical outcome.

Tick-borne encephalitis (TBE) and Lyme neuroborreliosis (LNB), the most common tick-borne diseases of the central nervous system in Central Europe, are frequently associated with pareses. The aim of this study was to characterise paretic complications in patients with TBE and LNB, including their severity, persistence and impact on the patients' quality of life. Our retrospective observational study included patients with aseptic CNS infection due to TBE virus or Borrelia burgdorferi sensu lato. Paretic complications were evaluated in the acute phase and the patients were followed up until complete regression or long-term stabilisation of any neurological deficit. The severity of the neurological deficit was graded according to the modified Rankin Scale (mRS). A total of 823 patients (582 with TBE, 241 with LNB) was included. Paretic complications were diagnosed in 63 TBE patients (10.8 %) and in 147 LNB patients (61.0 %). In TBE, the most common neurological deficit was brachial plexus paresis in 21 patients (33 %) and bulbar symptoms in 18 patients (29 %). In LNB patients, facial nerve palsy was the most frequent neurological deficit (117patients; 79.6 %), followed by lower limb paresis in 23 patients (15.6 %). Forty-nine TBE patients and 134 LNB paretic patients completed follow-up. Paresis resolved within 3 weeks in 16 TBE patients (33 %) and 53 LNB patients (39.5 %), but the proportion of patients with paresis persisting for more than 12 months was significantly higher in TBE (34.7 vs. 3.7 %, p < 0.001). The mean mRS was significantly higher in TBE paretic patients compared to LNB (p < 0.001). Paretic complications are significantly more common in LNB than in TBE but pareses associated with TBE last longer than in LNB and considerably reduce the quality of life of patients. Prevention remains the only way to influence the long-term motor deficits of TBE.

Rituximab leading to an atypical presentation of neuroborreliosis and false negative serology.

Two patients, recently treated with the B-cell-depleting monoclonal antibody, rituximab, had 2-3 months of progressive systemic symptoms; comprehensive investigations did not clarify the diagnosis. Transient radicular pain at disease onset had suggested neuroborreliosis, but seronegativity and an atypical clinical course made this unlikely. However, PCR identified Borrelia burgdorferi DNA in cerebrospinal fluid, establishing the diagnosis of neuroborreliosis. Both the clinical picture and the laboratory findings can be atypical in people with neuroborreliosis who have recently been treated with rituximab. In B-cell depleted patients living in endemic areas, one should suspect neuroborreliosis even when the typical symptoms are drowned out by more atypical symptoms; PCR should be used as a diagnostic supplement when the serological response is uncertain or absent.

Encefalitis aguda con síndrome cerebeloso secundario a neuroborreliosis / Cerebellar syndrome associated to Lyme neuroborreliosis: case report

La enfermedad de Lyme es la infección transmitida por garrapatas más común en Norteamérica y Europa. Sin embargo, en América Latina se han reportado pocos datos. Borrelia burgdorferi es capaz de invadir el sistema nervioso central causando la neuroborreliosis de Lyme. Se comunica el caso de una mujer joven con encefalitis y síndrome cerebeloso, una presentación poco frecuente, que se manifestó con cefalea, marcha atáxica, nistagmo y ptosis palpebral. Se realizó el diagnóstico con serología positiva por Western blot para Borrelia burgdorferi en suero. Recibió tratamiento con mejoría clínica. El diagnóstico de neuroborreliosis es difícil, ya que no existen hallazgos neurológicos o de imagen específicos. Se recomienda tener un mayor nivel de vigilancia epidemiológica en Latinoamérica, así como los antecedentes recreativos o viajes, que deben incluirse en la historia clínica para mejorar la aproximación diagnóstica.

Lyme disease is the most common tick-borne disease in North America and Europe. However, in Latin America, few data have been reported. Borrelia burgdorferi is capable of invading the central nervous system causing Lyme neuroborreliosis. This is a case report of a female with encephalitis and cerebellar syndrome, a rare manifestation, presented with generalized headache ataxic gait, nystagmus and palpebral ptosis. Serologic diagnosis was made for Borrelia burgdorferi and treatment was initiated with clinical improvement. Neuroborreliosis is a very difficult diagnosis, since there are no neurologic or imaging findings specific. It is recommended to physicians to have an enhanced level of surveillance in Latin America, as well as recreational/travel history of the patient, which should be included in the clinical record to improve the diagnostic approach.

Plasma Exchange for Lyme Neuroborreliosis delayed diagnosis: A case report.

Lyme neuroborreliosis (LNB) is a rare infectious disease, caused by Borrelia burgdorferi spirochetes and responsible for a variety of neurological manifestations. The most common manifestations of LNB in children are cranial nerve involvement, especially facial nerve palsy often accompanied by lymphocytic meningitis. In this article, we present a case of a 4-year-old boy presented to our emergency department with abdominal pain evolving for a week and symmetrical ascending progression of weakness responsible for severe respiratory failure. Diagnosis of Guillain-Barré syndrome (GBS) was initially suspected. Although our patient had received 2 courses (each of 5 days) of Intravenous immunoglobulin (IVG) treatment, no clinical improvement was observed. The diagnosis of LNB was confirmed by detection of both IgG and IgM specific antibodies in serum. The patient's muscle weakness got better after a 2- week course of Ceftriaxone but respiratory muscle failure didn't improve with two extubation failures. Consequently, we decided to conduct plasmapheresis procedures. We managed to extubate the child and discharge him after a good recovery of his symptoms. Pediatricians must consider LNB disease in the differential diagnosis of GBS, especially when the patient didn't recover after IVG treatment. This case shows that plasmapheresis could be effective for pediatric neuroborreliosis cases with severe neurological disorders.

Diagnosis of neuroborreliosis in the context of local seroprevalence: A chart review study and a methodological overview.

Background & objectives: In neuroborreliosis (NB) serology might objectively differentiate ongoing from past infection when the intrathecal space is involved. The hierarchy of the parallel serum-CSF (cerebrospinal fluid) methods is seldom discussed and remains elusive in daily practice. We compared the efficacy of certain methods and assessed the prevalence of anti-Borrelia antibodies in the local population. Methods: We summarized standard two-tier test results in all ELISA-reactive samples of patients with suspected NB (n=152) since 2017 and tested 122 unrelated sera for anti-Borrelia antibodies from central Hungary. Results: The most common central nervous system symptom was a cranial nerve palsy (27.6% of all subjects). CSF was available in 25 cases. A serum-CSF IgG-matched line immunoassay (LIA) detected intrathecal antibody production correctly in 6 of 8 samples when compared to the ELISA-based antibody-index (AI). Among the 122 random sera the prevalence of specific anti-Borrelia IgG antibodies (on LIA, not including anti-p41) were 6.8% above 30 and 10% above 60 years. Our results enable us to assume the predictive values of serological results according to the pretest probability of neuroborreliosis. Interpretation & conclusion: Our results suggest that recombinant antigen-based two-tier serology from solely the sera might have sufficient positive predictive value to verify NB in young individuals with characteristic anamnestic data in our region. When parallel serum-CSF testing is warranted, AI should have priority. IgG and albumin concentrations in the both serum and the CSF, the potential time of exposure and the nature and duration of symptoms form the bare minimal set of data for conclusive testing.

Bilateral facial nerve palsy as a presentation of coexisting neuroborreliosis and post-acute COVID-19 syndrome.

Bilateral simultaneous facial nerve palsy is an extremely rare condition that may be induced by infection (bacterial, viral, or fungal) or noninfective causes (autoimmune, traumatic, or structural). The treatment depends on the underlying disorder, and, if it is introduced on time, the disease is in most cases completely reversible. We report on a patient with bilateral simultaneous facial nerve palsy without an obvious cause. The possible causes were SARS-CoV-2 infection and postvaccination syndrome. After we excluded the SARS-CoV-2 infection, a wide range of diagnostic tests were conducted. Magnetic resonance imaging after gadolinium intravenous application showed bilateral facial nerve enhancement. Serological tests revealed Borrelia burgdorferi, and the result was confirmed by an enzyme-linked immunosorbent assay (IgM positivity). After 14 days of antibiotic therapy, the symptoms resolved completely without sequelae. This report shows that the symptoms of bilateral simultaneous facial nerve palsy may completely resolve if thorough clinical investigation and an appropriate early treatment are applied.

Bilateral diaphragmatic paralysis and Lyme neuroborreliosis. Ten-years of follow-up / Parálisis diafragmática bilateral y neuroborreliosis de Lyme. Diez años de seguimiento

Abstract Borrelia burgdorferi infection (Lyme disease) is one of the few identifiable causes of neuralgic amyotrophy (AN). Bilateral diaphragmatic paralysis is considered rare in borreliosis, and the pattern of long-term recovery of diaphragm function is also uncertain. Transdiaphragmatic pressure is the gold standard for diagnosing bilateral diaphragmatic paralysis, a study that has been reported on a few occasions. We pres ent a case of AN associated with borrelia infection and bilateral diaphragmatic paralysis that provides a detailed follow-up of the spirometric evolution, the maximum static pressures in the mouth, and the transdiaphragmatic pressure from the onset of symptoms and in the long term. This case allows us to know one of the possible evolutionary profiles of diaphragmatic dysfunction in AN due to borreliosis.

Resumen La infección por Borrelia burgdorferi (enfermedad de Lyme) es una de las pocas causas identificables de amiotrofia neurálgica. La parálisis diafragmática bilateral es considerada rara en la borreliosis y el patrón de recuperación a largo plazo de la función del diafragma también es incierto. La presión transdiafragmática es el patrón de oro para el diagnóstico de parálisis diafragmática bilateral, un estudio que ha sido informado en pocas ocasiones. Se presenta un caso de amiotrofia neurálgica asociado a infección por Borrelia y parálisis diafrag mática bilateral, que aporta un seguimiento detallado de la evolución espirométrica, de las presiones estáticas máximas en la boca y de la presión transdiafragmática desde el inicio de los síntomas y a largo plazo. Este caso permite conocer uno de los posibles perfiles evolutivos de la disfunción diafragmática en la amiotrofia neurálgica por borreliosis.

Manifestações neuroftalmológicas associadas a doença de Lyme / Neuro-ophthalmological manifestations associated with Lyme disease

Resumo A doença de Lyme é uma infecção sistêmica causada pela espiroqueta Borrelia burgdorferi e transmitida pelo carrapato do gênero Ixodes sp. e espécie Amblyomma cajennense. A doença costuma se manifestar em três estágios clínicos distintos, que podem variar de acordo com as características de cada hospedeiro. O objetivo deste trabalho é relatar o caso de uma paciente de 33 anos com doença de Lyme que apresentou como manifestações neuroftalmológicas diplopia, lagoftalmo paralítico e ceratite punctata, com exames laboratoriais negativos. Embora a espiroqueta Borrelia burgdorferi tenha maior tropismo pelos tecidos da pele, sistema nervoso e articulações, o acometimento ocular não deve ter sua importância diminuída, sendo descrito neste relato de caso, que abordou os aspectos mais pertinentes à doença para auxiliar seu diagnóstico e tratamento.

Abstract Lyme disease is a systemic infection caused by the spirochete Borrelia burgdorferi and transmitted by the tick of the genus Ixodes sp. and species Amblyomma cajennense. The disease usually manifests itself in three distinct clinical stages, which may vary according to the characteristics of each host. The objective of this paper is to report the case of a 33-year-old patient with Lyme disease who presented as neuro-ophthalmological manifestations diplopia, paralytic lagophthalmos and punctate keratitis, with negative laboratory tests. Although the spirochete Borrelia burgdorferi has a greater tropism in the tissues of the skin, nervous system and joints, the ocular involvement should not be diminished, being described in this case report, which approached the most pertinent aspects to the disease to aid its diagnosis and treatment.
