A Fatal Case of Presumptive Diagnosis of Leptospirosis Involving the Central Nervous System.

Leptospirosis is a reemerging zooanthroponosis with a worldwide distribution, though it has a higher incidence in areas with tropical climate. A characteristic finding of the disease is its wide spectrum of symptoms and organ involvement, as it can appear either with very mild flu-like manifestations or with multiorgan failure, affecting the central nervous system (CNS) with a concomitant hepatorenal dysfunction (Weil's syndrome) and significant high mortality rate. We report herein a fatal case of a 25 years old female, previously healthy, with impaired neurological status. She had high fever and severe multiorgan failure. The clinical data and the epidemiological factors were not conclusive for the diagnosis, and the first serology test from the cerebrospinal fluid (CSF) and sera samples were negative. When the repetition of the blood test showed elevated IgM antibodies, Leptospirosis was the presumptive diagnosis. Although CNS involvement is rare, the diagnosis should be considered when there is an elevated risk of exposure. The diagnostic protocol should encompass direct evidence of the bacterium and indirect measurement of antibodies. Timely detection and management are imperative to forestall complications and fatality associated with the disease.

A Case of Imported Leptospirosis: Rhabdomyolysis and Severe Hyperbilirubinemia in a Traveler Returning From Puerto Rico.

Leptospirosis is a zoonosis transmitted through human contact with the urine or fecal material of infected animals. Here, we report the case of a young male who presented with hyperbilirubinemia and rhabdomyolysis after returning from Puerto Rico which was confirmed to be severe leptospirosis. An 18-year-old Caucasian male was admitted due to a four-day history of jaundice, fever, headache, abdominal pain, vomiting, dark urine, and pain in his calves. Two weeks before, in Puerto Rico, he swam in caves and at the shoreline in an area recently impacted by a hurricane. Laboratory studies demonstrated leukocytosis, thrombocytopenia, hypokalemia, acute kidney injury with elevated creatine kinase, and hyperbilirubinemia. Due to clinical suspicion of leptospirosis, a serological test was ordered which was positive for Leptospira IgM. In this case, the history of swimming in caves and on the shoreline a few weeks after a hurricane that caused flooding in the region made leptospirosis the most likely diagnosis. The patient's condition improved after initiation of intravenous penicillin G, 8 million units/day, with a resolution of symptoms after completing a seven-day course of antibiotics. Bilirubin started to trend down on day seven, and the patient was discharged on day eight of hospitalization with minimal jaundice. It is important to obtain a detailed medical history when treating patients who have returned from tropical areas, as leptospirosis can mimic other diseases and can be easily mistaken or underrecognized in non-endemic regions, such as the continental United States.

Leptospirosis severa en el puerperio: informe de un caso / Severe leptospirosis in puerperium: a case report

Resumen ANTECEDENTES: La leptospirosis es una infección bacteriana que puede aparecer durante el embarazo o puerperio; su manifestación más grave es el síndrome de Weil, que puede provocar la muerte por choque séptico, insuficiencia multiorgánica y complicaciones hemorrágicas severas. CASO CLÍNICO: Paciente de 26 años, procedente de la provincia de Supe (Lima, Perú), en etapa puerperal, a quien se practicó cesárea cuatro días antes en una institución ajena al hospital. Acudió al hospital debido a la aparición de ictericia generalizada, fiebre de 39 °C, hepatoesplenomegalia, anasarca y síndrome de disfunción multiorgánica. Mediante la prueba de ELISA e IgM (subtipos Hursbridge 1/200 e Icterohaemorrhagiae 1/400) se estableció el diagnosticó de leptospirosis. En el noveno día se inició tratamiento con ceftriaxona. Cuatro semanas después tuvo mejoría clínica y fue dada de alta del hospital en condición estable. CONCLUSIONES: El diagnóstico de leptospirosis es incierto durante el embarazo, incluso un 10% de las pacientes afectadas podrían agravar su situación. Es importante vigilar el bienestar del feto y decidir la finalización del embarazo por la mejor vía, según las condiciones de la madre y el feto.

Abstract BACKGROUND: Leptospirosis is a rare infectious complication that could manifest during pregnancy or puerperium. The most severe form, the Weil syndrome, has elevated mortality due to septic shock, multiple organ failure and severe bleeding complications. CLINICAL CASE: A 26-year-old female underwent cesarean section due to high risk of loss of fetal well-being at an outside hospital. On the 4th day postpartum, she was referred to our center febrile (38-39 ° C), with generalized jaundice, anasarca and hepatosplenomegaly, with further deterioration into multiorgan dysfunction syndrome. Elisa IgM was positive for Leptospirosis, specifically for the subtypes Hursbridge 1/200 and Icterohaemorrhagiae 1/400. On the ninth day after admission, ceftriaxone was started. Four weeks later, she had clinical improvement and was discharged in stable condition. CONCLUSIONS: The diagnosis of leptospirosis infection is uncertain during pregnancy and up to 10% of affected patients could have complications. It is important to monitoring the fetal well being and determine the proper time of pregnancy termination by the best route of delivery if there are maternal or fetal indications.

Brote de 4 casos leptospirosis de un grupo familiar en zona rural tropical de Colombia: un reporte de caso / Outbreak of 4 leptospirosis cases in a family group in tropical rural zone of Colombia: a case report

La leptospirosis es una zoonosis con manifestaciones clínicas causadas por espiroquetas patógenas del género Leptospira spp. Su curso puede ser desde enfermedad leve hasta un síndrome ictero-hemorrágico severo denominado enfermedad de Weil. Se estudió un brote epidemiológico constituido por una serie de cuatro casos de leptospirosis de severidad moderada a severa, ocurridos en una zona rural de clima tropical en los llanos orientales de Colombia, a 450 metros sobre el nivel del mar en una familia visitante en Puerto Lleras, Meta, Colombia. Probablemente secundario al consumo de aguas contaminadas por orina de roedores. Las pacientes fueron ingresadas bajo la sospecha de un síndrome ictérico de origen infeccioso con un falso positivo para antígeno de superficie de hepatitis B. Dos pacientes desarrollaron síndrome de Weil asociado a microangiopatía trombótica por lo que requirieron manejo en unidad de cuidados intensivos (UCI) sin embargo, una de ellas fallece y las otras dos pacientes desarrollan signos y síntomas moderados evidenciando un curso variable de la enfermedad. En nuestro país existe una sobre notificación de síndromes febriles, ictéricos e icterohemorragicos de diferentes etiologías y difícil diagnóstico por lo que la leptospirosis tiende a ser confundida o ignorada como diferencial en muchos casos.

Leptospirosis is a zoonosis with clinical manifestations caused by pathogenic spirochetes of the genus Leptospira spp. Its course can range from mild illness to a severe jaundice-hemorrhagic syndrome called Weil's disease. An epidemiological outbreak consisting of a series of four cases of leptospirosis of moderate to severe severity, which occurred in a rural area with a tropical climate in the eastern plains of Colombia, at 450 meters above sea level, was studied in a visiting family in Puerto Lleras, Meta, Colombia. Probably secondary to the consumption of water contaminated by rodent urine. The patients were admitted on suspicion of an infectious jaundice syndrome with a false positive for hepatitis B surface antigen. Two patients developed Weil's syndrome associated with thrombotic microangiopathy, requiring ICU management, however, one of them died and the other two patients develop moderate signs and symptoms showing a variable course of the disease. In our country there is an overreporting of febrile, jaundice and jaundice syndromes of different etiologies and difficult diagnosis, so that leptospirosis tends to be confused or ignored as differential in many cases.

Terapia de reemplazo renal continua. Presentación de un caso / Continuous renal replacement therapy. Case report

RESUMEN La insuficiencia renal aguda es definida como la pérdida de función del riñón ocasionada por diversas causas, entre ellas infección e ingesta de fármacos. Esta entidad tiene alta morbilidad y mortalidad en las unidades de cuidados críticos. El tratamiento de la misma va desde la propia protección renal hasta la sustitución artificial de las funciones del riñón lesionado. En la actualidad la terapia de reemplazo renal continua se ha utilizado como soporte renal, y ofrece mayor estabilidad clínica a los pacientes más inestables. En esta revisión se comentan conceptos, indicaciones y los más recientes estudios que validan el uso de esta terapéutica, así como el método de programación que se utilizó en un paciente con diagnóstico de una leptospirosis icterohemorrágica (síndrome de Weil), que estuvo en shock séptico con disfunción multiorgánica, donde se empleó esta terapia con resultados satisfactorios (AU).

ABSTRACT Acute kidney failure is defined as the loss of kidney function caused by various causes, including infection and drug intake. This entity has high morbidity and mortality in critical care units. Treatment ranges from renal protection to artificial replacement of the functions of the injured kidney. Currently, continuous renal replacement therapy has been used as renal support, and offers greater clinical stability to the most unstable patients. In this review, authors discuss concepts, indications and the most recent studies that validate the use of this therapeutic, as well as the programming method that was used in a patient with diagnosis of icteric-hemorrhagic leptospirosis (Weil syndrome), who was in septic shock with multiorgan dysfunction, where this therapy was used with satisfactory results (AU).

Conclusiones: mediante un caso clínico de síndrome de Weil, se describe la afectación multisistémica de complicaciones asociadas con leptospirosis, con manifestaciones poco habituales como neuroleptospirosis, pericarditis y colestasis intrahepática(AU)

Introduction: Weil syndrome is a serious form of the bacterial infection caused by the Leptospira bacterium; this is known as leptospirosis. This is characterized by multiple organ dysfunction; for example, the liver, kidney, muscles, of serous type, or the neurological system, in this case called neuroleptospirosis, which produces a very high mortality when adequate diagnosis and treatment are not provided. Objective: To describe the clinical manifestations, complementary paraclinic practice and treatment of a patient with Weil syndrome, as a rare condition. Clinical case: 23-year-old patient who presents with acute febrile syndrome associated with optic neuritis, chest pain, and paraclinical symptoms obviously consistent liver and cardiac involvement. The diagnosis of Weil syndrome is confirmed, specifically defined by neuroleptospirosis, pericarditis, and intrahepatic cholestasis. Conclusions: Through a clinical case of Weil syndrome, the multisystem involvement of complications associated with leptospirosis is described, along with its unusual manifestations, such as neuroleptospirosis, pericarditis, and intrahepatic cholestasis(AU)

Leptospirosis-induced purpura: An atypical manifestation of Weil's disease.

Purpura is a rare but documented presenting feature of severe leptospirosis. We describe a case of Weil's disease characterized by predominating coagulopathy and hepato-nephritis. We illustrate dynamic changes in cutaneous lesions.

A case with high bilirubinemia and hemolytic anemia during leptospirosis and a short review of similar cases.

BACKGROUND: Leptospirosis is characterized by very diverse clinical manifestations, which may range from flu-like subclinical forms to very severe presentations characterized by multi-organ failure, or to atypical presentations. One of its most aggressive presentations is Weil's disease, characterized by jaundice, hemorrhagic phenomena and renal failure. Cases with high bilirubinemia over 30mg/dL are not communes in human leptospirosis. Our aims are to present an atypical case presentation of human leptospirosis, characterized by jaundice and hemolytic anemia, and to make a short review in PubMed for similar cases. At the same time we want to emphasize the diversity of the clinical presentation of human leptospirosis. METHODS: A 54-year-old man presents at the emergency department of the infectious medicine with severe fatigue, nausea, vomiting, and generalized weakness. On exam, he was alert and well oriented; blood pressure was 80/50 mmHg and icteric. First blood examinations confirmed high bilirubinemia, thrombocytopenia and acute renal failure. RESULTS: Based on anamnestic and clinical evaluations, blood and serology examinations, the patient resulted with leptospirosis. The bilirubin reached 73.4mg/dL. At the same time on PubMed research we found only limited cases with leptospirosis associated with bilirubinemia over 30mg/dL and over less with hemolytic anemia. CONCLUSION: Based on our clinical experience, as well as literature data, we suggest that clinicians should have a high index of suspicion in cases of jaundice with exposure possibilities for infectious diseases. Connection of high bilirubinemi over then 30mg/dL and hemolytic anemia in human leptospirosis is an unical case report.

Unusual presentation of urban leptospirosis complicated by a septic shock.

Leptospirosis, an infectious zoonosis, is common to tropical areas. The clinical presentation varies from flu-like symptoms to a serious presentation called Weil's syndrome. Fever and conjunctival suffusion are present in the majority of patients. This case report describes a resident of New York City who presented initially with gastroenteritis symptoms without fever or conjunctival suffusion to develop septic shock before being diagnosed with leptospirosis.

Pathology and pathogenesis of human leptospirosis: a commented review

Leptospirosis is an acute bacterial septicemic febrile disease caused by pathogenic leptospires, which affect humans and animals in all parts of the world. Transmission can occur by direct contact with infected animals or, more commonly, through indirect contact with water or soil contaminated with urine from infected animals. Leptospires enter the body by penetrating mucous membranes or skin abrasions and disseminate through the hematogenic route. In humans, leptospirosis may cause a wide spectrum of symptoms. Most cases have a biphasic clinical presentation, which begins with the septicemic phase followed by immune manifestations. The severe forms of the disease may be life threatening with multisystem damage including renal failure, hepatic dysfunction, vascular damage, pulmonary hemorrhage and muscle lesions. In this review, we present and discuss the pathogenesis of the human disease and the mechanisms of cell membrane injuries, which occur mainly due to the presence of leptospires and/or their antigen/s in the host tissues.

Cuadro ictérico hemorrágico grave causado por Leptospira interrogans serovar Icterohaemorrhagiae / Case of jaundiced severe bleeding caused by Leptospira interrogans serovar icterohaemorrhagiae

Resumen Se trata de un paciente con cuadro ictérico-hemorrágico grave causado por Leptospira interrogans quien presentó una hemorragia intracerebral, pulmonar y hepato-esplenomegalia. El estudio del daño tanto a nivel hepático como del bazo fueron hechos por tomografías axiales computarizadas, en tanto que el agente etiológico fue diagnosticado por la técnica de microaglutinación. El manejo terapéutico de la leptospirosis se realizó con penicilina, con buena evolución del paciente. Se presenta el caso de un cuadro ictérico hemorrágico estudiando los factores de riesgo, el desarrollo de la enfermedad y el manejo correcto del paciente contrastando la literatura.

Abstract We describe a patient with severe hemorrhagic- jaundiced-causedby Leptospira interrogans, who also presented an intracerebral hemorrhage, pulmonary and hepatosplenomegaly. The study of the liver and spleen damage were made by TC scans, while the etiologic agent was diagnosed by the microscopic agglutination technique. The therapeutic management of leptospirosis was performed with penicillin, with good outcomes. We present the case of a patient with jaundice and hemorrhage and his risk factors, similarly the development of disease and the proper patient management.

Clinical and laboratory manifestation and outcome of icterohemorrhagic leptospirosis patients in Northern Iran.

BACKGROUND: Icterohemorrhagic form of leptospirosis has a high mortality rate. In this study, the clinical manifestations, epidemiologic and laboratory findings and outcome of Weil's disease were investigated. METHODS: A descriptive cross- sectional study was conducted on 66 consecutive patients with icterohemorrhagic leptospirosis who were admitted to Razi Hospital (The Therapeutic Center of Infectious Diseases in the North of Iran) in 2013. The inclusion criteria were as follows: All patients who had clinical and epidemiological data suggestive of leptospirosis and displayed icterohemorrhagic form at the time of admission or during hospitalization. All patients were visited on admission, one, two and six weeks later. Demographic data, clinical, laboratory features and complications were evaluated, and statistical analysis was performed using SPSS version 13.0. RESULTS: Among 66 patients, 89.4% (n = 59) were male, 60% (n = 40) were farmers and 9.1% (n= 6) had a history of swimming in rivers. The most common complaints were fever and jaundice, respectively. The most common clinical symptoms were fever (90.9%), myalgia (75.8%), chills (70.8%) and headache (65.1%). Hyponatremia and hypernatremia were seen in 7.6% and 72.8% of the participants, respectively. Also, hypokalemia was observed in two patients (3%). Approximately, half of the cases had leukocytosis and 90% had thrombocytopenia. Rise of AST, ALT, ALP and bilirubin were seen in 95.2%, 93.6%, 76.2% and 100% of the patients, respectively. Of the patients, 42.4% experienced complications of icterohemorrhagic leptospirosis including acute renal failure (30.3%) pneumonia (25.8%), pancreatitis (4.5%), subarachnoid hemorrhage (1.5%) and gastrointestinal bleeding (1.5%). Three cases (4.5%) died, 42 cases (63.7%) were discharged with residual effects and 52 patients (78.8%) had positive serology. CONCLUSION: The most significant biochemical abnormalities were thrombocytopenia, hyperbilirubinemia, hyponatremia and hypernatremia and azotemia and the latter remained stable in 2% of the patients at least until the end of the 6-week period.

Atrial flutter complicating severe leptospirosis: a case report

Cardiac disturbances are relatively common and electrocardiographic abnormalities may be found in more than 70% of patients with leptospirosis. We report the case of a 68 year-old male with severe leptospirosis who developed atrial flutter. Effective treatment was done with amiodarone. The patient became clinical stable, with complete recovery. Rigorous clinical observation and continuous electrocardiogram (ECG) monitoring may facilitate the identification of rhythm disorders, and thus prevent a probable fatal outcome, in severe cases of leptospirosis.

An unusual case of Weil's syndrome with paraparesis.

Leptospirosis is an important emerging zoonosis with a worldwide distribution that is characterized by a broad spectrum of clinical manifestations ranging from inapparent infection to fulminant disease. Leptospirosis has protean clinical manifestations. The classical presentation of the disease is an acute biphasic febrile illness with or without jaundice. Unusual clinical manifestations may result from involvement of pulmonary, cardiovascular, neural, gastrointestinal, ocular and other systems. Immunological phenomena secondary to antigenic mimicry may also be an important component of many clinical features and may be responsible for reactive arthritis. The presentation of paraparesis in combination with Weil's syndrome is rare. Few cases were reported with leptospirosis and paraparesis in India and abroad. It is important to bear in mind that leptospiral illness may be a significant component in cases of dual infections or in simultaneous infections with more than two pathogens. Here we are reporting a case of Weil's syndrome with paraparesis in 28-year-old male patient who was critically ill due to severe hepatorenal dysfunction and hyperkalemia.

Sporadic urban leptospirosis.

Severe leptospirosis (Weil Syndrome) was diagnosed in an otherwise healthy environmental worker in Baltimore alleys in late November 2010. He developed multiple organ failure but responded to antibiotic therapy and experienced a full recovery within 4 weeks. His diagnosis was confirmed by a rise in indirect hemagglutinin titer (acute 0, convalescent 400). The subject had close contact with Baltimore alley rats; a similar epidemiologic exposure and location reported in an outbreak 15 years ago.
