Lung fragments from 12 patients were collected immediately after death and studied by light and electron microscopy and by immunohistochemistry to describe the main morphologic and ultrastructural aspects of the lung and platelets in leptospirosis (Weil's syndrome), to search for the possibility of disseminated intravascular coagulation (DIC), and to assess the relationship between endothelial lesions and local platelet aggregation and the leptospiral antigen distribution, as well as its relationship with the intensity of the lesions. The immunohistochemical results for fibrin aggregates were positive in the lumen and/or on the vascular endothelium in nine cases and on the alveolar surface in seven cases, leading to the diagnosis of the adult respiratory distress syndrome in these seven cases. Test results for leptospiral antigen by immunohistochemistry were positive in eight cases with no direct relationship between antigen deposits in the pulmonary vascular endothelium and intensity of the lesions. The ultrastructural findings were uniform and constant. Capillary lesions were characterized by swelling of endothelial cells, an increase in pinocytotic vesicles, and giant dense bodies in the cytoplasm of these cells. No necrosis, rupture, nor exposed subendothelial collagen was observed outside the hemorrhagic areas, and the intercellular junctions were preserved. The lung involvement in severe human leptospirosis presents as hemorrhagic pneumopathy with septal capillary lesions that are the usual cause of death. The thrombocytopenia that was verified in 11 of 12 patients in our study seems to bear no relationship to DIC and seems to be determined by activation, adhesion, and aggregation of platelets to the stimulated vascular endothelium, with an amorphous electron-dense substance between the endothelial cells and the adherent platelets in places where the subendothelial collagen was not exposed.

Acute leptospirosis in Europe (Weil's disease) is a rare and in more than 90% of the cases undiagnosed febrile, self-limited disease. We report the case of a 39-year-old sewerage worker, who was admitted to our hospital with fever, jaundice, pain in his calves and acute renal failure. Serology revealed elevated antibody titers against Leptospira canicola, L. icterhaemorrhagica and L. sejroe. The patient developed disseminated intravascular coagulation (DIC) with diffuse gastrointestinal bleeding due to thrombocytopenia. The ECG showed atrial fibrillation with irregularly irregular rhythm. Cardiac arrest developed, most likely due to hypoxia, with a drop in the blood pressure. Despite immediate resuscitation efforts the patient developed severe hypoxic brain damage and died a few days later. Autopsy disclosed histologic signs of a generalized leptospiral infection, signs of shock and within the lungs a necrotizing herpes simplex virus pneumonia causing the death of the patient. The virus pneumonia most probably was caused by retrograde canalicular dissemination of oral secretions since herpetic tracheitis and esophagitis were found and herpetic lesions were readily identified on the lips and tongue. A medical opinion asked for by the professional association having liability for occupational safety and insurance was given, the disease being recognized as an occupational disease.

We describe a 2 year-old non-immunocompromised girl with disseminated histoplasmosis who presented with a 2-month history of fever and bloody diarrhoea. On presentation, she was severely wasted and anaemic. There were gross hepatosplenomegaly and multiple lymphadenopathy. A septic screen was negative. A subsequent stool culture isolated Salmonella enteriditis. Serial Widal-Weil Felix (WWF) titres showed serological response after 2 weeks of Ceftriaxone. However, she continued to have spiking fever, bloody diarrhoea and weight loss. She developed pancytopaenia and disseminated intravascular coagulation. A bone marrow aspirate and trephine, and lymph node biopsy showed the presence of Histoplasma capsulatum, confirmed by Gomori-Methenamine Silver staining. She responded to intravenous amphotericin B followed by fluconazole (intravenous then oral) for 6 months after discharge. Human Immunodeficiency Virus screening tests were negative. Complement and immunoglobulin levels were normal. T and B enumeration tests showed gross leucopaenia with very low T cell function with defective phagocytic function. A repeat T and B cell enumeration test and phagocytic function tests done 3 months later were normal.

A 34-year-old woman presented with septic shock, disseminated intravascular coagulation (DIC), and multiorgan dysfunction with a 1-week history of fever, abdominal pain in the right upper quadrant, and dull pain in the right flank. Physical and laboratory data showed cytopenia (thrombocytopenia and anemia), splenomegaly, hyperferritinemia, hypofibrinogenemia, and an elevated level of interleukin-2 receptor (soluble CD25). Bone marrow examinations disclosed hypercellular marrow with increased infiltration of histiocytes with hemophagocytosis. This diagnosis was confirmed by positive Weil-Felix test results (Proteus mirabilis OX-K titer, 1:80), the presence of IgG and IgM antibodies, and positive PCR results for Orientia tsutsugamushi. The patient developed a severe intracranial hemorrhage 3 days after admission and expired due to systemic inflammatory response syndrome with DIC and multiorgan failure on the 13th day of hospitalization. Scrub typhus with hemophagocytic syndrome can be complicated by DIC and multiorgan failure. Patients with scrub typhus usually have an excellent response to treatment; therefore, early diagnosis and prompt administration of antimicrobial therapy may prevent the development of serious complications.
