We examined the changes in plasma levels of soluble thrombomodulin in 66 cases of disseminated intravascular coagulation (DIC), to investigate the damage to vascular endothelial cells and its relationship to multiple organ failure. A significant elevation of plasma levels of soluble thrombomodulin was observed in most cases of DIC, especially in patients with sepsis. However, no such significant elevation was observed in patients with acute promyelocytic leukemia. Plasma levels of both soluble thrombomodulin and active plasminogen activator inhibitor were higher in the cases of DIC with multiple organ failure than in those without multiple organ failure. The levels of soluble thrombomodulin were decreased with the clinical improvement in most cases of DIC but were further increased or remained at high levels in patients who showed no improvement of DIC. It was suggested that an increase in soluble thrombomodulin indicates the damage to the vascular endothelial cells in cases of DIC and that the damage to vascular endothelial cells plays some role in further progression of multiple organ failure.

In order to assess the thrombin and plasmin generation in vivo in disseminated intravascular coagulation (DIC), plasma levels of thrombin-antithrombin III (ATIII) complex (TAT) and plasmin-alpha 2-antiplasmin (a2AP) complex (PAP) were measured together with standard coagulation and fibrinolytic parameters in 80 patients with DIC. Both TAT and PAP were markedly elevated in patients with DIC. When plotted by the underlying disease categories, differences in the magnitude of the elevations of these complexes were recognized among groups. Patients with acute promyelocytic leukemia (APL) had the highest PAP, the lowest TAT/PAP ratio, low a2AP, and low fibrinogen, indicating that the most excessive fibrinolysis can occur in APL. Similar profiles, although less marked, were observed in patients with other leukemias and vascular diseases. Patients with sepsis showed the highest TAT/PAP ratio and the lowest PAP with no decrease in a2AP or fibrinogen, demonstrating a relatively impaired fibrinolysis. Patients with cancer had a relatively high TAT and high TAT/PAP ratio. In addition, both TAT and PAP were markedly elevated in patients with shock. From these, it was suggested that, although laboratory manifestations in DIC are extremely variable from patient to patient, underlying disorders are, at least in part, responsible for the observed variations. Recognition of this variable activation of coagulation and fibrinolysis would be helpful for the proper management of patients with DIC.

In disseminated intravascular coagulation (DIC) with acute promyelocytic leukemia (APL) in the absence of severe infection, marked fibrinolysis was noted in comparison with normal levels of antithrombin III, which is a major inhibitor of the coagulation system. Increased plasminogen activator inhibitor-1 (PAI-1) antigen levels in plasma from patients with septicemia decreased the ratio of the plasma clot lysis rate induced by an anti-alpha 2-plasmin inhibitor monoclonal antibody to the tissue-type plasminogen activator (t-PA) concentration. This decrease was not as prominent in plasma from patients with DIC, especially those with APL. To explore the character of PAI-1 in these plasmas, we measured the specific activity of PAI-1 by determining the ratio of active PAI-1 antigen to t-PA-unbound PAI-1 antigen. To calculate the amount of active PAI-1 antigen, the amount of t-PA/PAI-1 complex before and after the addition of a fixed amount of t-PA to the sample was measured by a sandwich solid-phase enzyme-linked immunosorbent assay using anti-PAI-1 and anti-t-PA monoclonal antibodies. The assay to measure total PAI-1 antigen used three monoclonal anti-PAI-1 antibodies and had similar sensitivities to free active, latent, vitronectin-bound and t-PA-bound PAI-1. The specific activity of PAI-1 decreased in patients with DIC (43.7% +/- 30.6%) and in DIC cases with APL (10.3% +/- 6.0%) in comparison to patients with septicemia (83.7% +/- 20.2%) or normal controls (85.8% +/- 27.3%). In DIC associated with APL, degraded forms of PAI-1 were detected in plasma by immunoblotting. These results suggest that a decrease in the specific activity of PAI-1 and an increase in secondary fibrinolysis result in a hyperfibrinolytic state in DIC patients with APL.

A 33-year-old man was hospitalized because of thrombocytopenia and severe splenomegaly. On admission 78% of peripheral lymphoid cells were abnormally large, with pale cytoplasm. Flow cytometry of the abnormal lymphocytes showed that they expressed CD 2, CD 3, CD 11, CD 16, and CD 56, but not CD 4 nor CD 8, so they were T-cell large granular lymphocytes (T-LGL). Abnormal lymphocytes obtained from a lymph node expressed CD 2, CD 16, CD 38, and CD 56, but not CD 3, CD 4, and CD 8, so they were natural killer(NK) cells. Splenectomy was performed and the operative specimen showed diffuse infiltration of pleomorphic lymphocytes, probably chronic lymphocytic leukemia cells. After splenectomy, the platelet count returned to normal but the lymphocytosis continued. Two years after discharge, chemotherapy was done because of thrombocytopenia and hepatomegaly. The patient died of disseminated intravascular coagulation arising from sepsis. The differences and similarities between peripheral and lymph-node lymphocytes suggest that LGL and NK cells may be differentiated from the same kind of cell, somewhat differentiated from stem cells.

In Japan, we experienced the first case of Hafnia alvei septicemia with shock and disseminated intravascular coagulation (DIC) in an adult with postoperative lung cancer. A 63 year-old male, who had been followed up in our department since 1987, was admitted to our hospital with the complaints of fever, hemoptysis and dyspnea on June 25, 1989. After admission, he was treated with sulbactam/cefoperazone 4 g/day intravenously for suspicion of respiratory-tract infection. After antibiotic administration, the fever subsided and the general condition became almost good. The patient experienced fever again after the antibiotic was stopped. For this reason subsequent Clavulanic acid/Amoxicillin, Flomoxef, and Ceftazidime was administered, but was not effective. Therefore septicemia was suspected and blood culture was done. The bacteria isolated from blood culture was identified as Hafnia alvei. Hafnia alvei is a gram-negative organism belonging to the Enterobacteriaceae family and quite rare pathogen in human.

A case of massive haemolytic anaemia in the course of a C. perfringens sepsis of hepatic origin is presented. The diagnosis was strongly suggested by the presence of intragranulocytic capsulated bacilli in a Giemsa stained peripheral blood smear. The patient developed disseminated intravascular coagulation. The outcome was fatal and the patient died eight hours after admission. We review the aetiopathogenesis, diagnosis and therapy of haemolysis in Clostridium perfringens infections.

A 54-year-old man received insertion of an acupuncture needle into the region extending from the posterior neck to the back on two occasions for the treatment of shoulder stiffness. Two weeks after the second acupuncture, he developed fever, dysarthria and mictionary disturbance, finally reaching the condition of tetraplegia. He was immediately admitted to an emergency room in our hospital, and was diagnosed as sepsis with DIC, ARDS, heart failure, renal failure, liver failure, and myelitis. After one month, he recovered with transverse myelopathy as a residual deficit. Neurological findings showed transverse myelopathy below the level of Th2 at that time. Cervical CT revealed an irregular low density at the periphery of the cervical vertebra from the C2 to C4 level. Cervical MRI revealed an irregular swelling of his spinal cord from the C2 to C7 level. We explained the mechanism of transverse myelopathy in this case as follows. After the acupuncture, he suffered a focal infection of the region of needle insertion, and then the infection expanded to the cervical vertebra, thus causing osteomyelitis, sepsis, and finally cervical myelitis. Direct injury of the spinal cord and nerve roots as a complication of acupuncture was previously reported, but indirect injury of the spinal cord due to myelitis had not been reported except our present case. Careful attentions should be paid to the complications of acupuncture.

So-called "Postoperative Erythroderma" was experienced in a 68 year-old man who received CABG for unstable angina. After a seemingly uneventful recovery, he revealed high grade fever on 13th post operative day (POD), rashes over the whole body on 15th POD and pancytopenia on 20th POD. He died of sepsis, multiple organ failure and DIC on 21st POD. Blood transfusion (concentrated red cell: 3 units) was done on operation. In this case, the rate of premature and atypical lymphocytes increased, and the ratio of OKT4 (helper)/OKT8 (suppressor) decreased. These findings of the examination suggested that there was a possibility of cell-mediated immunological depression. We considered this to be acute GVHD after blood transfusion.

The authors give an account on the relations between disseminated intravascular coagulation, sepsis and multiorgan failure. Disseminated intravascular coagulation is defined as an acquired disorder of blood clotting with an increased turnover of thrombocytes, fibrinogen and coagulation factors. The authors discuss aetiopathogenetic aspects, possibilities of laboratory diagnosis, anticoagulation and substitution therapy and prophylaxis of disseminated intravascular coagulation in septicaemia. They emphasize comprehensive treatment of septicaemias where haematological monitoring and therapy must form an integral part. In an extensive series of septic multiorgan failures the authors detected failures apparent on laboratory examination in 41% of the patients.
