1/115. leukostasis followed by hemorrhage complicating the initiation of chemotherapy in patients with acute myeloid leukemia and hyperleukocytosis: a clinicopathologic report of four cases.

    BACKGROUND: Pulmonary and cerebral leukostasis, or parenchymal hemorrhage in these organs, are well-known early complications developing in patients with acute myeloid leukemia (AML), particularly when myelomonocytic features, hyperleukocytosis, and/or a coagulation disorder are initially present. Commonly, these complications arise during increasing leukocyte counts (WBCs). methods: The authors describe four patients with AML and hyperleukocytosis who developed leukostasis followed by parenchymal hemorrhage. RESULTS: Bleeding in all patients occurred while their WBCs were decreasing following cytosine-arabinoside chemotherapy, and in the absence of disseminated intravascular coagulation or severe thrombocytopenia. Radiologic and histopathologic findings underscoring possible mechanisms are presented in the article. CONCLUSIONS: Alterations of cell adhesion associated with chemotherapy-induced blast lysis or cellular differentiation are possible factors contributing to this particular sequence (cytosine arabinoside-based chemotherapy, leukostasis, and subsequent hemorrhage). Prophylactic measures for managing this early complication of AML treatment include leukapheresis to reduce the WBC prior to the initiation of chemotherapy.

2/115. White-centred retinal haemorrhages (Roth spots).

    Roth spots (white-centred retinal haemorrhages) were classically described as septic emboli lodged in the retina of patients with subacute bacterial endocarditis. Indeed many have considered Roth spots pathognomonic for this condition. More recent histological evidence suggests, however, that they are not foci of bacterial abscess. Instead, they are nonspecific and may be found in many other diseases. A review of the histology and the pathogenesis of these white-centred haemorrhages will be provided, along with the work-up of the differential diagnosis.

3/115. A fatal case of autoimmune thrombocytopenia with an IgM anti-GPIb/IX following one antigen mismatched unrelated donor bone marrow transplantation.

    We report the case of a 32-year-old patient with ALL who developed autoimmune thrombocytopenia 2 months following allogeneic bone marrow transplantation. An IgM autoantibody against the platelet glycoprotein Ib/IX complex was observed. Treatment with high-dose steroids and intravenous immunoglobulin g failed to produce any benefit and the thrombocytopenia led to fatal gastrointestinal haemorrhage. The possible factors contributing to post-allograft thrombocytopenia and potential management strategies are discussed.

4/115. Acute left ventricular dysfunction and subarachnoid hemorrhage.

    OBJECTIVE: Severe left ventricular (LV) dysfunction associated with acute subarachnoid hemorrhage (SAH) due to cerebral aneurysm rupture. SETTING: An adult 12-bed surgical intensive care unit of a university hospital. PATIENT: A female patient presenting with SAH (Hunt & Hess grade III) and severe left ventricular dysfunction. INTERVENTIONS: central venous pressure, arterial blood pressure, extravascular lung water catheter, transesophageal echocardiography, blood gas analysis, electrocardiograms, and chest x-ray for clinical management. MEASUREMENTS AND MAIN RESULTS: On admission to the district hospital, an electrocardiogram (ECG) revealed a sinus rhythm with transient ST elevations. A transesophageal echocardiography showed a left ventricular ejection fraction (LV-EF) of approximately 10%. Severe LV dysfunction required inotropic and vasopressor support to maintain mean arterial pressure above 60 mmHg, while the first measurement of an extravascular lung water catheter revealed a cardiac index of 2.0 L/min/m2 and moderate hypovolemia. Despite stepwise volume loading that increased intrathoracic blood volume--an indicator of cardiac preload--from 719 mL/m2 to 927 mL/m2, cardiac index remained poor. enoximone lead to a marked increase of cardiac index up to 3.9 L/min/m2 and LV-EF to about 30%, but had to be stopped due to thrombopenia. Surgical clipping of an intracranial aneurysm was postponed because of the impaired cardiac function and was performed on day 18 after admission. Interestingly, neurologic outcome was not as poor as might be expected from the literature. CONCLUSION: Severe left ventricular dysfunction may occur in acute SAH and may necessitate delay of aneurysm surgery.

5/115. Disseminated nocardiosis as a complication of Evans' syndrome.

    Nocardiosis is an opportunistic infection caused by gram-positive, weakly acid-fast filamentous aerobic organisms. Three species cause infection in man: N. asteroides, N. brasiliensis, and N. caviae, the first one being the most common. With increased use of immunosuppressive therapy for various autoimmune diseases, opportunistic infection by nocardia has increasingly been reported. N. asteroides infections manifest in various ways; the lungs, skin, and brain are the organs most frequently involved. We describe a patient with Evans' syndrome, a disease requiring long-term immunosuppression, who acquired systemic nocardiosis. The infection was primarily pulmonary, misdiagnosed as tuberculosis, with subsequent hematogenous dissemination to the skin and central nervous system. The diagnosis of cerebral involvement was difficult to prove, as the patient presented with stroke-like episodes. After a positive blood culture was obtained, antibiotic therapy was introduced. The patient's condition deteriorated and the brain with infiltration of the meninges, lungs, skin, and kidneys. nocardia is an important but often overlooked opportunistic infectious agent in immunocompromised hosts, causing diagnostic and therapeutic problems. As the mortality of cerebral nocardiosis is greater than 80%, early diagnosis and appropriate therapy are crucial.

6/115. sagittal sinus thrombosis associated with thrombocytopenia: a report of two patients.

    Reported are two patients presenting with both thrombocytopenia and sagittal sinus thrombosis. The first patient is a 42-month-old male with no identified thrombophilic risk factors who developed acute neurologic symptoms after an acute infection. The second patient is a 22-month-old female with no history of preceding infection but had a positive lupus anticoagulant test. She also developed deep venous thrombosis and was treated with intravenous heparin. Both patients are currently doing well without neurologic deficits. To the authors' knowledge the second patient is the youngest reported patient with cerebral vein thrombosis associated with thrombocytopenia and lupus anticoagulant. These observations call attention to the need for a thorough investigation of thrombophilic risk factors in pediatric patients with thrombotic complications.

8/115. Multiple major cerebral artery thromboses with profound thrombocytopenia in acute leukaemia.

    A child with acute lymphoblastic leukaemia complicated by prolonged gastrointestinal and skin haemorrhages due to profound thrombocytopenia finally died of thrombotic occlusions of major cerebral arteries due to mucormycosis. biopsy of any suspect lesion is needed urgently before prolonged therapy with amphotericin b is started. So far there have been no cures in childhood.

9/115. intestinal pseudo-obstruction in systemic lupus erythematosus: an uncommon but important clinical manifestation.

    OBJECTIVES: To document intestinal pseudo-obstruction (IpsO) as a recognised clinical manifestation of systemic lupus erythematosus (SLE) and a possible new clinical entity with its apparent association with ureterohydronephrosis. METHODOLOGY: We report six lupus patients who presented with IpsO and review 12 other cases from an English literature search. IpsO is defined as the presence of clinical features suggestive of intestinal obstruction but without organic obstruction, namely absence of bowel sounds, presence of multiple fluid levels on plain abdominal x-rays and exclusion of organic obstruction by imaging or surgical procedure. Other clinical characteristics related to the underlying lupus, serological and histological findings, treatment modalities and outcomes of these patients were reviewed. RESULTS: All 18 patients fulfilled the ACR revised classification criteria for SLE. None showed any clinical features of scleroderma or overlap syndrome. The mean age of onset of IpsO was 29.0 (15-47) y. The female to male ratio was 16:2. Nine patients had IpsO as the initial presentation of their underlying lupus. Coexisting lupus involvement of other organ systems included glomerulonephritis (n=7), thrombocytopenia (n=5) and cerebral lupus (n=3). The serology data and autoantibody profile of some of the previously reported patients were incomplete. In our series, anti-Ro antibody was positive in 5/6 while anti-RNP was found in 1/6 patients only. All our patients had active lupus serology at presentation. 17/18 patients required the use of high dose systemic corticosteroid therapy while one patient responded to topical adrenocorticotrophin hormone treatment. Response was good and was observed early after commencement. azathioprine was used as maintenance therapy in 6/18 patients with good effects. An apparent association with the presence of bilateral ureterohydronephrosis was found in 12/18 patients. These patients presented with dysuria without positive bacterial culture though features of chronic interstitial cystitis were not invariably found in these patients. CONCLUSION: IpsO is an uncommon but important manifestation of SLE. The underlying pathology is not fully understood but it may be related to immune complex deposition. The finding of coexisting ureterohydronephrosis suggests that there may also be a central smooth muscle motility problem of neuropathic or myogenic pathophysiology which may or may not be secondary to vasculitis. Early recognition and treatment of IpsO in SLE is important.

10/115. Neurologic complications in immune-mediated heparin-induced thrombocytopenia.

    OBJECTIVE: To evaluate neurologic complications in patients with immune-mediated heparin-induced thrombocytopenia (HIT) with respect to incidence, clinical characteristics, outcome, and therapy. methods: One hundred and twenty consecutive patients with immune-mediated HIT were recruited over a period of 11 years and studied retrospectively for the occurrence of neurologic complications. Diagnosis of HIT was based on established clinical criteria and confirmed by detection of heparin-induced antibodies using functional and immunologic tests. RESULTS: Eleven of the 120 patients (9.2%) presented with neurologic complications; 7 suffered from ischemic cerebrovascular events, 3 from cerebral venous thrombosis, and 1 had a transient confusional state during high-dose heparin administration. Primary intracerebral hemorrhage was not observed. The relative mortality was much higher (Chi-square test, p < 0.01) in HIT patients with neurologic complications (55%) as compared to patients without neurologic complications (11%). The mean platelet count nadir in neurologic patients was 38 /- 25 x 10(9)/l on average, and was lower in patients with fatal outcome compared to those who survived (21 /- 13 x 10(9)/l versus 58 /- 21 x 10(9)/l; p < 0.05, Wilcoxon test). In three patients neurologic complications preceded thrombocytopenia. There was a high coincidence of HIT-associated neurologic complications with other HIT-associated arterial or venous thrombotic manifestations. CONCLUSION: Neurologic complications in HIT are relatively rare, but associated with a high comorbidity and mortality. HIT-associated neurologic complications include cerebrovascular ischemia and cerebral venous thrombosis. They may occur at a normal platelet count.
