A 47-year-old man presented with a history of fever, chills and weight loss for 3 months. He had been treated for diabetes mellitus during the past 3 years. He developed high fever with abnormal liver function tests. Both Widal and Weil-Felix reactions were negative with normal roentgenogram of the chest. His anti-HIV tests were positive. The cultures from the blood and sputum yielded pure Sphingobacterium multivorum sensitive to sulfamethoxazole-trimethoprim, chloramphenicol, tetracycline, cefotaxime, ceftazidine and ceftriaxone. On the next day, the patient developed signs and symptoms of meningitis with the CSF containing chronic and acute inflammatory cells but revealed no growth on culture. The patient was treated with a combination of ceftriazone and trimethoprim-sulfamethoxazole but he died on the 6th day after admission. This patient was the fifth reported case infected with S.multivorum. It illustrates that this potentially pathogenic organism can cause septicemia in an immunodeficient patient.

Leptospirosis is a world-spread zoonosis that is incidentally acquired by humans. It causes a diphasic febrile illness in which the Weil syndrome is its severest form, with renal, hepatic, clotting and central nervous system involvement. We report a 73 years old male, that was admitted to an intensive care unit with multiple organ failure due to leptospirosis. The clinical picture initially resembled a sepsis due to biliary tract obstruction and was operated, not finding a biliary tract obstruction. Considering the history of a fall to sewed waters, leptospirosis was suspected and treatment with penicillin was started, obtaining a full recovery of the patient.

Leptospirosis is a common disease in Latin America. Transmission to humans occurs by contact with water or soil contaminated with the urine of rodents, dogs, or livestock. Pathogenesis is still poorly understood, and bacterial toxin or virulence factors are probably responsible for many features of the disease. The anicteric form is the most frequent presentation, and its clinical picture resembles influenza or other acute febrile diseases. Icterohemorrhagic leptospirosis, or Weil's syndrome, represents the severe form of the disease. Its clinical picture is similar to bacterial sepsis and multiple organ involvement occurs, mainly in kidneys and lungs, and causes great morbidity and mortality. Death is often related to multiple organ failure and pulmonary hemorrhages. Diagnosis is based on serology or blood, cerebrospinal fluid and urine cultures in specific media. Treatment involves a combination of antibiotics and supportive measures.

Leptospirosis is a widespread spirochetal zoonosis caused by the members of the genus Leptospira. The natural history of human leptospiral infection varies widely. The infection can cause a subclinical illness, or may be mistaken for influenza. In individuals who become ill, leptospirosis typically presents as one of two clinically recognizable syndromes. The first syndrome is the mild anicteric form, which rarely results in death, while the second syndrome fulminant icteric form, known as Weil's syndrome, has an associated 10% mortality. The anicteric form comprises two disease stages, namely the septicemic phase and the immune phase. In fever work up, leptospirosis is usually not the first considered pathogen of sepsis, unless jaundice and ARF are present. This study investigated two patients with leptospirosis presenting with conscious disturbance and oligoric acute renal failure individually. In the second patient, persistent hypokalemia and metabolic alkalosis developed during recovery from acute renal failure. Several tubular function tests were performed to define the renal tubular lesion in this patient, revealing a defect on the thick ascending limb. This study also reviews previous studies on leptospirosis including its epidemiology, pathogenesis, clinical presentation, diagnosis, treatment, and prognosis.

One of the important causes of acute febrile illness in a country where malaria, typhoid and dengue are also not uncommon, leptospirosis, a zoonotic disease spread by rodents, is endemic in Tamil Nadu, Kerala and Andamans; and is now being increasingly reported from other parts of India, perhaps with better facility to diagnose the disease. Disease of profound importance in view of its grave outcome, in its icteric form (Weil's disease), may have a mortality of as high as 40%. Worst prognosticator is the presence of multi-organ failure (MOF), as in any other septicemia. Andaman hemorrhagic fever (AHF), a type peculiar to Andamans, is now being described elsewhere in the country also. IgM ELISA, Dot-ELISA, dip-stick method and slide agglutination test (SAT) are newer screening methods for diagnosis of leptospirosis, but are only genus-specific. Identifying specific serovar is possible by Micro-agglutination test (MAT) and culture method only. Anicteric type of disease, however, is easily treatable with penicillin and has a good prognosis. Oral doxycycline can be used for prophylaxis during the risk of exposure.

Over 30 years ago Weil and Shubin proposed a re-classification of shock states and identified hypovolemic, cardiogenic, obstructive and distributive shock. The first three categories have in common that they are associated with a fall in cardiac output. Distributive shock, such as occurs during sepsis and septic shock, however, is associated with an abnormal distribution of microvascular blood flow and metabolic distress in the presence of normal or even supranormal levels of cardiac output. This Bench-to-bedside review looks at the recent insights that have been gained into the nature of distributive shock. Its pathophysiology can best be described as a microcirculatory and mitochondrial distress syndrome, where time and therapy form an integral part of the definition. The clinical introduction of new microcirculatory imaging techniques, such as orthogonal polarization spectral and side-stream dark-field imaging, have allowed direct observation of the microcirculation at the bedside. Images of the sublingual microcirculation during septic shock and resuscitation have revealed that the distributive defect of blood flow occurs at the capillary level. In this paper, we classify the different types of heterogeneous flow patterns of microcirculatory abnormalities found during different types of distributive shock. Analysis of these patterns gave a five class classification system to define the types of microcirculatory abnormalities found in different types of distributive shock and indicated that distributive shock occurs in many other clinical conditions than just sepsis and septic shock. It is likely that different mechanisms defined by pathology and treatment underlie these abnormalities observed in the different classes. Functionally, however, they all cause a distributive defect resulting in microcirculatory shunting and regional dysoxia. It is hoped that this classification system will help in the identification of mechanisms underlying these abnormalities and indicate optimal therapies for resuscitating septic and other types of distributive shock.

Two specific serological tests, a Dot enzyme immunoassay (EIA) and an immunoglobulin (Ig)M enzyme-linked immunosorbent assay (ELISA) using the 56 kDa antigen and the Weil-Felix test were evaluated for diagnosis of scrub typhus. Sensitivity of 100, 86.5 and 43.5% were observed with Dot EIA, IgM ELISA and Weil-Felix test, respectively. False-positive reactions were observed in patients with falciparum malaria, pulmonary tuberculosis, S. viridans septicemia and typhoid fever using Dot EIA and IgM ELISA. Therefore, although Dot EIA and IgM ELISA are useful in the serodiagnosis of scrub typhus, efforts should be made to rule out other febrile illnesses.

We present a case of fulminant leptospirosis that was acquired in the suburban area by a 48-year-old male renal transplant recipient. He developed acute renal and hepatic failure with profound jaundice. Spirochetes were identified on liver biopsy. Weil's disease was suspected, and the diagnosis was further supported by a positive serum Leptospira interrogans icterohaemorrhagiae antibody titer. Unfortunately, he suffered from recurrent lower gastrointestinal bleeding, had a prolonged hospital course, and eventually succumbed to overwhelming sepsis. This case is the third report to our knowledge of leptospirosis in a renal transplant recipient in the English literature.

Lemierre's syndrome is a suppurative thrombophlebitis involving the internal jugular vein, most commonly associated with Fusobacterium necrophorum, usually a complication of oropharyngeal infections. This syndrome is rare and is often overlooked. We present a case of sepsis mimicking initially severe leptospirosis (Weil's disease) due to acute febrile illness with multiorgan failure and hyperbilirubinemia. Finally, blood cultures revealed Fusobacterium necrophorum and computed tomography (CT) demonstrated bilateral pulmonary nodules and a thrombus in the right internal jugular vein. Early clinical suspicion is crucial so that appropriate diagnostic investigation and antibiotic therapy can be initiated to minimize the risk of life-threatening complications.

In leptospirosis, severe pulmonary hemorrhagic syndrome has replaced Weil's disease as the main cause of mortality, with rates of up to 75%. Four men, all farmers, were admitted to the intensive care unit between August 2009 and July 2010 with a diagnosis of acute respiratory distress syndrome. All patients presented with fever, hemoptysis, bilateral pulmonary infiltrates in chest radiographs, and thrombocytopenia and had compatible epidemiological history with leptospirosis; 3 patients had anemia, 3 had renal failure, 2 had increased creatine kinase, whereas bilirubin was slightly increased in only 1 patient. Leptospirosis was diagnosed serologically in all cases. Empirical therapy with ceftriaxone was administered immediately to all patients, while implementation of ARDSnet protective mechanical ventilation approach combined with an early goal-directed hemodynamic approach led to a relatively low mortality rate (25%). Acute Physiology and Chronic Health Evaluation II, Simplified Acute Physiology Score II and Sepsis-Related Organ Failure Assessment scoring systems were unable to predict the outcome of the patients with leptospirosis-associated severe pulmonary hemorrhagic syndrome.
