A 75-year-old man was admitted to our hospital because of intermittent fever. His peripheral blood picture showed granular lymphocyte (GL) proliferation. The GLs were immunologically and functionally phenotyped as natural killer cells. Chromosomal analysis of peripheral lymphocytes with interleukin-2 stimulation revealed an inversion of chromosome 9 with an unusual breakpoint, showing abnormal monoclonal proliferation of the GLs. Progressive increase of GL count and hepatosplenomegaly necessitated the start of combined chemotherapy. His condition was complicated by icterus and renal failure, and he died finally of respiratory failure. Autopsy revealed disseminated intravascular coagulation and infiltration of GLs in the bone marrow, spleen, and liver.

To investigate the role of neutrophil activation in the pathophysiology and sequelae of disseminated intravascular coagulation (DIC), we measured plasma levels of granulocyte elastase-alpha 1-proteinase inhibitor complex (GEPIC) in 41 patients with DIC and 27 patients with similar underlying conditions but without DIC. Mean GEPIC levels were significantly higher in patients with DIC (421.0 +/- 45.6 ng/ml) than in patients without DIC (246.1 +/- 41.9 ng/ml, P < 0.01). Significant differences were also noted in DIC patients with or without infection (474.7 +/- 61.2 ng/ml vs. 302.4 +/- 48.9 ng/ml, P < 0.04), with or without organ dysfunction (546.6 +/- 72.7 ng/ml vs. 305.6 +/- 42 ng/ml, P < 0.01), and with or without respiratory failure (640.0 +/- 91.2 ng/ml vs. 328.1 +/- 55.1 ng/ml, P < 0.01). No significant difference was found in mean GEPIC levels in DIC patients with or without renal failure, heart failure, hepatic failure, or gastrointestinal bleeding. The frequency of respiratory failure correlated with rising plasma levels of GEPIC. Mortality was higher in patients with GEPIC levels > 500 ng/ml (53.8%) than in patients with GEPIC levels < 500 ng/ml (28.6%). This correlation was particularly strong in patients with DIC, infection, and respiratory failure. Based on these data, we suggest that neutrophil activation, triggered by the coagulation cascade and perhaps augmented by endotoxin or cytokine release with infection, significantly contributes to respiratory failure and mortality in patients with DIC.

We administered surfactant to a 5-month-old infant with respiratory failure due to right pulmonary haemorrhage accompanied by oedema following abdominal surgery. These pathological conditions were probably precipitated by disseminated intravascular coagulation and intra-operative excessive administration of fluids, respectively. Endobronchial instillation of the exogenous surfactant (120 mg) after selective intubation of the right bronchus produced a dramatic improvement of gas exchange 30 min after treatment and of chest X-ray findings at 6 h post-treatment. This case on an infant indicates that administration of surfactant may be one of promising therapeutic approaches to respiratory failure due to pulmonary haemorrhage.

We studied four patients who presented a striking elevation of blood transaminases suggesting acute hepatitis. The post mortem histological examination of the liver revealed centrolobular necrosis that is commonly diagnosed as ischaemic hepatitis. The liver necrosis arose from heart failure which was worsened by an acute anaemia in one patient and by a severe hypoxemia, due to respiratory failure, in another. In three subjects there was evidence of disseminated intravascular coagulation that may be responsible for aggravating the condition of liver hypoxia. The authors also review the literature on the various aspects of ischaemic hepatitis.

Patients with leukemia, lymphoma, or multiple myeloma are prone to critical illness because of the diffuse nature of their disease and the disruption of protective mechanisms. Despite high morbidity rates, a number of these patients have an excellent probability of long-term remission if supported through a crisis. Complications that cause critical illness can be categorized as related to disease or those caused by therapy. Those with unique features or management strategies for the hematologic malignancy patient and are included in this discussion include: leukostasis, disseminated intravascular coagulation, tumor lysis syndrome, respiratory failure, and typhlitis. A case study of an acutely ill, newly diagnosed patient with several of these oncologic emergencies is used to exemplify typical clinical finds and management strategies.

A 61-year-old man with a history of hypertension and diabetes mellitus had a tooth extracted. Nine days later, he was admitted to the hospital with complaints of high fever, dyspnea, and anterior chest pain. Physical examination revealed a drowsy man with a fever of 38.2 degrees C, blood pressure of 66/44 mmHg, and marked redness and swelling from the neck to anterior part of the chest. Laboratory examination indicated severe infection and multiple organ failure, consisting of cardiac, respiratory, renal, and hepatic failure, with disseminated intravascular coagulation. Chest X-ray and CT-scan films showed abscesses extending from the neck to the mediastinum, and bilateral pleural effusion. Immediately, he was treated with catecholamines, furosemide, mechanical ventilation with a high concentration of oxygen, continuous drainage, repeated skin incisions, and broad-spectrum antibiotics. In addition, steroid pulse therapy was administered for persistent respiratory failure. On the 28th hospital day, a fistula developed between the trachea and the mediastinum, and an intratracheal tube had to be inserted through the fistula. On the 212 th hospital day, after intravenous hyperalimentation, continuous intravenous insulin infusion, and administration of broad-spectrum antibiotics, catecholamines, and furosemide, the patient was weaned from mechanical ventilation. A restrictive ventilatory defect due to ankylosis and atrophy of underused muscles was noted after weaning, but the PaO2 was high with a low dose of oxygen (1 to 2 l/min), and 21 months later, the blood gases were normal while the patient was breathing room air. As of January, 1996, he was undergoing rehabilitation to promote his recovery from ankylosis, muscle atrophy, and speech dysfunction.

We analyzed the clinical and laboratory characteristics of 50 patients with catastrophic antiphospholipid syndrome (APS) (5 from our clinics and 45 from a MEDLINE computer-assisted review of the literature from 1992 through 1996). Thirty-three (66%) patients were female and 17 (34%) were male. Twenty-eight (56%) patients had primary APS, 15 (30%) had defined systemic lupus erythematosus (SLE), 6 (12%) had "lupus-like" syndrome, and 1 (2%) had rheumatoid arthritis. Mean age of patients in this series was 38 +/- 14 years (range, 11-74 yr). Three (6%) patients developed the clinical picture of catastrophic APS under the age of 15 years, and 11 (22%) were 50 years old or more. In 11 (22%) patients, precipitating factors contributed to the development of catastrophic APS (infections in 3, drugs in 3, minor surgical procedures in 3, anticoagulation withdrawal in 2, and hysterectomy in 1). The presentation of the acute multi-organ failure was usually complex, involving multiple organs simultaneously or in a very short period of time. The majority of patients manifested microangiopathy--that is, occlusive vascular disease affecting predominantly small vessels of organs, particularly kidney, lungs, brain, heart, and liver--with a minority of patients experiencing only large vessel occlusions. Thrombocytopenia was reported in 34 (68%) patients, hemolytic anemia in 13 (26%), disseminated intravascular coagulation in 14 (28%), and schistocytes in 7 (14%). The following antibodies were detected: lupus anticoagulant (94%), anticardiolipin antibodies (94%), anti-dsDNA (87% of patients with SLE), antinuclear antibodies (58%), anti-Ro/SS-A (8%), anti-RNP (8%), and anti-La/SS-B (2%). Anticoagulation was used in 70% of the patients, steroids in 70%, plasmapheresis in 40%, cyclophosphamide in 34%, intravenous gammaglobulins in 16%, and splenectomy in 4%. Most patients, however, received a combination of nonsurgical therapies. Death occurred in 25 of the 50 (50%) patients. In most, cardiac problems seemed to be the major cause of death. In several of these, respiratory failure was also present, usually due to acute respiratory distress syndrome and diffuse alveolar hemorrhage. Among the 20 patients who received the combination of anticoagulation, steroids, and plasmapheresis or intravenous gammaglobulins, recovery occurred in 14 (70%) patients. The use of ancrod and defibrotide appeared to be effective in the 2 respective patients in whom they were used.

A review of 50 patients who manifest features of the catastrophic antiphospholipid syndrome (CAPS) is presented. The clinical features comprise mainly organ involvement as opposed to large-vessel venous or arterial occlusions as is seen in patients with 'simple' antiphospholipid syndrome (APS), which makes the pathogenesis of this unusually rare complication perhaps somewhat different from that of patients with the APS. The mortality of the condition is 50%, most patients dying as a result of a combination of cardiac and respiratory failure. Fifteen patients (28%) suffered from disseminated intravascular coagulation (DIC) as well, which may have contributed to the multiorgan thrombotic microangiopathy characteristic of the CAPS. Although most patients were treated with high-dose i.v. steroids, heparin, cyclophosphamide and other modalities of therapy (such as i.v. globulin), plasmapheresis (advocated for TTP, a similar microangiopathic condition) seemed to offer some benefit (68% recovery). The systemic inflammatory response syndrome (SIRS) was responsible for some of the clinical manifestations such as adult respiratory distress syndrome (ARDS) seen in 15 patients. Pathogenesis of the CAPS seems dependent on a 'two-hit' or even 'three-hit' hypothesis in patients already suffering from a hypercoagulable state. Precipitating factors include infections, trauma (surgical), drug administration and warfarin withdrawal. A recent view that the multiple thrombotic lesions themselves may contribute to further thrombosis ('thrombotic storm') is also discussed.

Severe pneumococcal pneumonia may precipitate both respiratory failure and neutropenia. The prognoses are considered to be very poor in such cases. We encountered three patients with pneumococcal pneumonia presenting respiratory failure and neutropenia, and successfully treated two. All three patients showed disseminated intravascular coagulation, and respiratory failure requiring mechanical ventilation. Neutropenia was treated with granulyte-colony stimulating factor (G-CSF), with methylpredonisolone administered by pulse therapy for 3 days to treat severe respiratory failure during the clinical course. All 3 patients were relieved of their respiratory failure at least for a few days following treatment. As a result of treatment with antibiotics and G-CSF, pneumococci disappeared from the patients' sputum. However, it has been reported that disintegration of the bacterial cell walls can release inflammatory components capable of causing secondary inflammatory reactions in the lung tissue. This suggested that the worsening respiratory failure experienced by our patients during their clinical course was a result of such reactions, and that methylpredonisolone was effective as the treatment of inflammation.

A 37-yr-old man underwent an open drainage operation for severe acute pancreatitis and received respiratory ventilation support for 4 mo because of respiratory failure based on disseminated intravascular coagulation (DIC) and septic shock. Under intensive care, he sometimes had bloody diarrhea for about 6 wk. Colonoscopic findings suggested that the bleeding had derived from the small intestine. The patient then gradually recovered from acute pancreatitis and was discharged from the hospital. Thereafter, he suffered relapses of ileus and his symptoms progressively worsened. The patient underwent a second operation about 2 yr after the onset of acute pancreatitis. At celiotomy, multiple stenoses of the distal ileum measuring about 60 cm in length were found and the segment was resected. The resected specimen demonstrated six separate circumferential strictures and shallow ulcerations. Histologically, multiple ulcerations were restricted to the mucosa and were accompanied by marked submucosal edema and fibrosis. The mucosa between the ulcers revealed chronic regenerative changes: intimal thickening of small mesenteric arteries causing luminal narrowing and organized thrombosis in small mesenteric veins. Therefore, these were considered to be a series of segmental ischemic lesions. Note that delayed ischemic stricture of the small intestine may occur as a chronic complication of acute pancreatitis.
