          Abstract

          INTRODUÇÃO: A doença de Lyme (DL) é uma doença de picada de carrapato, causado pela espiroqueta Borrelia burgdorferi sensu lato, transmitida por carrapatos do complexo Ixodes ricinus, que promove múltiplas manifestações clínicas sistêmicas. No Brasil, uma síndrome diferente é descrita e mimetiza sintomas de DL, mas também se manifesta com alta frequência de episódios recorrentes e manifestações alérgicas e imunológicas. É transmitida pelo carrapato Amblyomma cajennense e o agente etiológico é uma espiroqueta não cultivável de forma atípica. Devido a essas particularidades, esta zoonose emergente tem sido denominada síndrome brasileira semelhante à doença de Lyme ou síndrome de Baggio-Yoshinari (SBY). OBJETIVO: Descrever o espectro da manifestação neurológica da SBY. PACIENTES: Foram analisados 30 pacientes com SBY e sintomas neurológicos. RESULTADOS: A média de idade dos pacientes foi de 34,2 ± 13,3 anos (6 a 63 anos); 20 eram mulheres e 10 homens. Um alto número de episódios recorrentes (73,6%) e distúrbios psiquiátricos e psicossociais graves (20%) foram características típicas. Eritema migrans similar ao visto em hemisfério norte foi identificado em 43,3% dos pacientes no início da doença. A recorrência das lesões cutâneas diminuiu com a progressão da doença. Sintomas articulares (artrite) aconteceram em aproximadamente metade dos pacientes com SBY no início e durante o episódio de recidiva. CONCLUSÕES: A SBY é considerada uma nova doença transmitida por carrapato no Brasil que difere da clássica DL observada no hemisfério norte. A SBY reproduz sintomas neurológicos observados na DL, exceto pela presença adicional de recorrência de episódios e uma tendência de causar manifestações neurológicas crônicas e articulares.

          INTRODUCTION: Lyme disease (LD) is a tick-borne disease, caused by Borrelia burgdorferi sensu lato spirochetes, transmitted by Ixodes ricinus complex ticks, which leads to multiple systemic clinical manifestations. In Brazil, a different syndrome is described that mimics LD symptoms, but that also manifests high frequencies of recurrent episodes and immune-allergic manifestations. It is transmitted by the Amblyomma cajennense tick and the etiological agent is an uncultivable spirochete with atypical morphology. Due to its particularities, this emerging zoonosis has been called Brazilian LD-like syndrome or Baggio-Yoshinari Syndrome (BYS). OBJECTIVE: To describe the neurological spectrum of BYS. PATIENTS: Thirty patients with neurological symptoms of BYS were analyzed. RESULTS: Mean age of patients was 34.2 ± 13.3 years old (6 to 63 years); 20 were females and 10 males. A high number of recurrent episodes (73.6%) and severe psychiatric or psycho-social disturbances (20%) were distinguishing features. Erythema migrans similar to those seen in the Northern hemisphere was identified in 43.3% of patients at disease onset. The recurrence of skin lesions diminished as the disease progressed. Articular symptoms (arthritis) happened in nearly half of patients at BYS onset and during relapsing episodes. CONCLUSIONS: The BYS is considered a new tick borne disease in Brazil that differs from classical LD observed in the Northern hemisphere. BYS replicates most of the neurological symptoms observed in LD, except for the additional presence of relapsing episodes and the tendency to cause chronic neurological and articular manifestations.

          Chronic neurologic manifestations of Lyme disease.

          Lyme disease, caused by the tick-borne spirochete Borrelia burgdorferi, is associated with a wide variety of neurologic manifestations. To define further the chronic neurologic abnormalities of Lyme disease, we studied 27 patients (age range, 25 to 72 years) with previous signs of Lyme disease, current evidence of immunity to B. burgdorferi, and chronic neurologic symptoms with no other identifiable cause. Eight of the patients had been followed prospectively for 8 to 12 years after the onset of infection. Of the 27 patients, 24 (89 percent) had a mild encephalopathy that began 1 month to 14 years after the onset of the disease and was characterized by memory loss, mood changes, or sleep disturbance. Of the 24 patients, 14 had memory impairment on neuropsychological tests, and 18 had increased cerebrospinal fluid protein levels, evidence of intrathecal production of antibody to B. burgdorferi, or both. Nineteen of the 27 patients (70 percent) had polyneuropathy with radicular pain or distal paresthesias; all but two of these patients also had encephalopathy. In 16 patients electrophysiologic testing showed an axonal polyneuropathy. One patient had leukoencephalitis with asymmetric spastic diplegia, periventricular white-matter lesions, and intrathecal production of antibody to B. burgdorferi. Among the 27 patients, associated symptoms included fatigue (74 percent), headache (48 percent), arthritis (37 percent), and hearing loss (15 percent). At the time of examination, chronic neurologic abnormalities had been present from 3 months to 14 years, usually with little progression. Six months after a two-week course of intravenous ceftriaxone (2 g daily), 17 patients (63 percent) had improvement, 6 (22 percent) had improvement but then relapsed, and 4 (15 percent) had no change in their condition. Months to years after the initial infection with B. burgdorferi, patients with Lyme disease may have chronic encephalopathy, polyneuropathy, or less commonly, leukoencephalitis. These chronic neurologic abnormalities usually improve with antibiotic therapy.

              Lyme disease: a neuropsychiatric illness.

              Lyme disease is a multisystemic illness that can affect the central nervous system (CNS), causing neurologic and psychiatric symptoms. The goal of this article is to familiarize psychiatrists with this spirochetal illness. Relevant books, articles, and abstracts from academic conferences were perused, and additional articles were located through computerized searches and reference sections from published articles. Up to 40% of patients with Lyme disease develop neurologic involvement of either the peripheral or central nervous system. Dissemination to the CNS can occur within the first few weeks after skin infection. Like syphilis, Lyme disease may have a latency period of months to years before symptoms of late infection emerge. Early signs include meningitis, encephalitis, cranial neuritis, and radiculoneuropathies. Later, encephalomyelitis and encephalopathy may occur. A broad range of psychiatric reactions have been associated with Lyme disease including paranoia, dementia, schizophrenia, bipolar disorder, panic attacks, major depression, anorexia nervosa, and obsessive-compulsive disorder. Depressive states among patients with late Lyme disease are fairly common, ranging across studies from 26% to 66%. The microbiology of Borrelia burgdorferi sheds light on why Lyme disease can be relapsing and remitting and why it can be refractory to normal immune surveillance and standard antibiotic regimens. Psychiatrists who work in endemic areas need to include Lyme disease in the differential diagnosis of any atypical psychiatric disorder. Further research is needed to identify better laboratory tests and to determine the appropriate manner (intravenous or oral) and length (weeks or months) of treatment among patients with neuropsychiatric involvement.
