Molecular Detection of Leptospira in Two Returned Travelers: Higher Bacterial Load in Cerebrospinal Fluid Versus Serum or Plasma.

Leptospirosis is a potentially severe illness in returned travelers. Patients often present with fever, headache, and neck pain, which may lead to a workup for meningitis including the acquisition of cerebrospinal fluid (CSF). Although Leptospira DNA has been detected in CSF by polymerase chain reaction (PCR), little data exist regarding the utility of testing CSF in addition to serum or plasma obtained on presentation. In this report, we present two cases of leptospirosis in returned travelers presenting with fever and headache. Our first patient had neutrophilic meningitis, and Leptospira was detectable only in CSF obtained on admission. The second patient had a normal CSF profile, but Leptospira was detected in CSF at a bacterial load 5- to 10-fold higher than that in plasma. CSF is an important specimen for the diagnosis of Leptospira by molecular methods and may yield an actionable diagnosis in the absence of leptospiremia.

Neuroleptospirosis with hydrocephalus and very elevated cerebrospinal fluid protein.

To our knowledge, this is the first known case of a patient with leptospirosis and very elevated CSF, which caused hydrocephalus.

Clinical and biological symptoms of neuroleptospirosis are misleading. We report a 62-year-old man, without any risk factor, suffering from febrile headache with a pseudotumoral cerebral spinal fluid due to neuroleptospirosis. Thereby, we present useful diagnostic assays and their practical interest.

Guillain-Barre syndrome in a pediatric patient following infection due to Leptospira.

Leptospirosis is a disease with protean manifestations. We report a case of Guillain-Barre syndrome (GBS) in a pediatric patient following infection with Leptospira. Infecting Leptospira presumably belonged to serovar Copenhageni. The patient recovered completely. The possibility of GBS developing as a result of antecedent leptospiral infection should be kept in mind.

Detection of Leptospira DNA in patients with aseptic meningitis by PCR.

Samples of cerebrospinal fluid from 103 patients with aseptic meningitis were tested by PCR for detection of leptospires, and the results were compared with those of the microscopic agglutination test (MAT) and an enzyme-linked immunosorbent assay for detection of immunoglobulin M (ELISA-IgM). Of these samples, 39.80% were positive by PCR and 8.74 and 3.88% were positive by MAT and ELISA-IgM, respectively.

14 cases that were admitted to the Hospital Universitario de Caracas, between 1.989 and 1.994, with a definitive diagnosis of Leptospirosis by microaglutination of live antigens were studied. Most of them hospitalized at the gastroenterology service. The serovar most frequently found was icterohemorragiae 11 cases. There was a predominium for the male gender 12/2 and the majority of patients belonged to the range of age between 31 and 40. The most common forms of presentations were: fever (14), jaundice (10) and myalgias (10) while the most relevant findings at physical examination were: jaundice (12), fever (11) and hepatomegaly (8). All patients had abnormal laboratory tests and among these, aminotransferases, bilirrubin, creatinin, CPK, platelets and urinary sediment were more frequently altered. Only half of the patients were diagnosed as Leptospirosis at the moment of admission. We conclude that even though Leptospirosis is an infectious disease distributed worldwide only few cases are hospitalized and differential diagnosis is difficult because of diversity of clinical presentations and lack of laboratory resources. It is important for gastroenterologists because most of complicated cases present as jaundiced patients.

From January 1st up to September 30th 1990, 77 patients with leptospirosis diagnosis confirmed by laboratory studies were admitted at the Infectious and Parasitic Disease Service of the Hospital das Clínicas of the Universidade Federal de Pernambuco. The neurological exam was abnormal in 70 of the patients (90.91%). The cerebrospinal fluid (CSF) examination was carried out on 67 (87%) of the patients; it was abnormal in 64 (95.52%) yielding hypercytosis in the majority of cases. There was no difference in the CSF behavior in report to the several neurological forms nor in relation to the icteric or non-icteric forms of the disease. Significant were the results for the microscopic agglutination tests for leptospirosis in the CSF.

From January 1st up to September 30th 1990, 77 patients with leptospirosis were admitted at the Infectious and Parasitic Diseases Service of the Hospital das Clínicas of the Universidade Federal de Pernambuco. The majority (64) were male patients, and average age was 28 years old. Serovars icterohaemorrhagic and canicola were the most frequent. CSF examination was performed in 67 (87.0%) patients and it was abnormal in 64 (95.52%). Micro-agglutination test for leptospirosis with live antigens was performed in CSF, as well as immunological tests for syphilis, cysticercosis and schistosomiasis for differential diagnosis. Concerning the serovar identification, results of microagglutination test for leptospirosis in CSF were significant considering the similitude of responses when compared to those found for blood samples.

Leptospirosis: análisis de 36 casos 1983-1984 / Leptospirosis: analysis of 36 cases 1983-1984

Se analizó el cuadro clínico y la epidemiología de 36 casos del leptospirosis hospitalizados durante los meses de verano 1983-1984, los que se estudiaron por reacción de aglutinación microscópica usando 8 a 12 antígenos. No hubo relación entre el serotipo y la forma clínica. El cuadro clínico fue variado desde una evolución febril corta o otras con compromiso hepático renal y meningitis aséptica. Los serotipos más frecuentes fueron L. grippotyphosa, L. ballum, L. canícola y L. autumnalis lo que difiere de estudios anteriores hechos en este hospital. La evolución fue benigna en todos los casos. Para el mejor conocimiento de los diferentes cuadros clínicos que se producen en el curso de la infección por leptospiras, es necesario la comprobación por el laboratorio, mediante procedimientos que actualmente tienen un alto costo

Leptospirosis: a neglected cause of nonbacterial meningoencephalitis.

Two cases of leptospirosis with different clinical presentations are presented. The importance of recognizing mild, nonicteric and meningoencephalitic forms in order to identify vectors and contaminated areas and prevent further infections is emphasized. Cerebrospinal fluid (CSF) findings in reported cases of leptospirosis are reviewed and possible prognostic implications of CSF xanthrochromia, hypoglycorrhachia, persistent polymorphonuclear leukocytosis, and increased intracranial pressure are discussed.
