Coagulation profiles were performed in 30 consecutive alcoholic cirrhotic patients without known infection, malignancy, recent surgery, transfusion, or alcoholic intake. Hemorrhagic phenomena were present in 70% and included gastrointestinal bleeding, oozing from venipuncture sites, bruising, and epistaxis. All 30 patients had multiple liver function and coagulation abnormalities, the most frequent of which were increases in F VIII components and decreases in F XI and F VII. Also decreased in half or more of the 30 patients were Fletcher F, F II, F X, prothrombin time (PT), partial thromboplastin time (APTT), thrombin time (TT), reptilase time (RT), anti-thrombin III, and plasminogen. When comparing cirrhotic bleeders with nonbleeders, four parameters were significantly different in those with a bleeding tendency: F VII, anti-thrombin III, plasminogen, and albumin. The prolonged APTT was associated in four cases with a blocking inhibitor of unknown etiology. The prolonged TT and RT, in the absence of fibrin split products, fibrin monomers, DIC, or shortened euglobulin lysis time in any patient were suggestive of an abnormal fibrinogen, a dysfibrinogen. In three other patients, there was an inhibitor of the TT. Further investigation of the suspected dysfibrinogen in 21 patients by SDS-polyacrylamide gel electrophoresis revealed that the molecular weights of the Aalpha, Bbeta, and gamma polypeptide chains of fibrinogen were not different from normal. Two-dimensional immunoelectrophoresis of the suspected dysfibrinogen was similar to normal in 18 of 21 patients, with loss of the initial shoulder in three.

22 patients with severe preeclampsia-eclampsia were treated in our Intensive Care Unit from 1972 to 1978. Control of convulsions was achieved by diazepam, diphenylhydantoin and phenobarbital. In 11 comatose patients brain monitoring was carried out by frequent neurological examination and use of computerized x-ray tomography; aspiration of gastric contents was prevented by nasotracheal intubation. Brain oedema therapy included controlled hyperventilation, steroids and mannitol (7 patients). 10 patients with respiratory failure (due to pulmonary oedema, "shock lung" or aspiration pneumonitis) were treated by mechanical ventilation. Diastolic blood pressure above 100 mm Hg was reduced by hydralazine. Diuresis was induced by normalization of hypovolaemia with albumin and plasma expanders. Six patients died (27%); main causes of death included intracerebral haemorrhage, brain oedema, heart failure, acute pulmonary thromboembolism and bleeding from DIC.

Acute promyelocytic leukemia(APL) is a subtype of acute myelocytic leukemia(AML) associated with unique features such as the presence of atypical promyelocytes and bleeding tendency due to disseminated intravascular coagulation(DIC). In a retrospective study, we analyzed 96 cases of AML seen at our hospital between June, 1989 and December 1993. Thirteen cases of APL(14%) were identified and their clinicopathologic characteristics were analyzed. The 86 cases of other types of AML served as controls. The distinct clinicopathologic features of APL as contrasted to other types of AML included younger age of patients, shorter duration of symptom before diagnosis, higher level of albumin at presentation, and a higher proportion of patients having coagulation abnormalities (75 vs. 25%). Bone marrow cellularity was higher in APL when compared to other types of AML (100 vs. 90%, P = 0.013). Of 13 patients with APL, 4 died of bleeding/sepsis between days 2 to 4 after admission. Seven of 9 patients who received induction therapy achieved complete remission(CR). CR rate in APL was similar to other types of AML (78 vs. 64%, P = 0.743). Five of seven patients who achieved CR remain in continuous CR at 9+ to 42+ months. CR duration is significantly longer in APL when compared to other types of AML (P = 0.029). In conclusion, this study showed that APL is a distinct entity among subtypes of AML with clinically significant bleeding tendency and rapidly fatal course if untreated. With appropriate antileukemic therapy, CR can be achieved in the majority of patients and the patients show a longer duration of CR when compared to other types of AML.

Proteolytic enzymes, lipase, kinins, and other active peptides liberated from the inflamed pancreas convert inflammation of the pancreas, a single-organ disease of the retroperitoneum, to a multisystem disease. Adult respiratory distress syndrome, in addition to being secondary to microvascular thrombosis, may be the result of active phospholipase A (lecithinase), which digests lecithin, a major component of surfactant. Myocardial depression and shock are suspected to be secondary to vasoactive peptides and a myocardial depressant factor. Coagulation abnormalities may range from scattered intravascular thrombosis to severe disseminated intravascular coagulation. Acute renal failure has been explained on the basis of hypovolemia and hypotension. The renin-angiotensin alterations in acute pancreatitis (AP) as mediators of renal failure need to be studied. Metabolic complications include hypocalcemia, hyperlipemia, hyperglycemia, hypoglycemia, and diabetic ketoacidosis, of which hypocalcemia has been long recognized as an indicator of poor prognosis. The pathogenesis of hypocalcemia is multifactorial and includes calcium-soap formation, hormonal imbalances (e.g., parathyroid hormone, calcitonin, glucagon), binding of calcium by free fatty acid-albumin complexes, and intracellular translocation of calcium. Subcutaneous fat necrosis, arthritis, and Purtscher's retinopathy are rare. The various prognostic criteria of AP and other associated laboratory abnormalities are manifestations of systemic effects. Early recognition and appropriated management of these complications have resulted in improved prognosis of severe AP.

Various hemostatic abnormalities have been reported and excess activation of coagulation factors, such as prothrombin, factor VII, factor IX, and factor XI, have been detected in thrombotic diseases states by various assay systems. We recently developed the enzyme-linked differential immunoassay for activated factor XI-alpha 1 antitrypsin complex (FXIa-alpha 1 AT) and applied it with other assays for activated factors such as thrombin-antithrombin III complex (TAT) to detect the hypercoagulable state in clinical samples. In patients with DIC, the FXIa-alpha 1 AT level in plasma increased before onset of DIC. In patients with non-insulin-dependent diabetes mellitus, FXIa-alpha 1AT and TAT levels were increased in the patient plasma. FXIa-alpha 1AT was related to the severity of urinary albumin excretion, whereas TAT was not. Plasma FXIa-alpha 1AT levels were significantly increased in patients with angiographically proven coronary artery disease, and showed a positive correlation with TAT, fibrinogen, and Lp(a). Evaluation of activated coagulation factor provides useful information on the diagnosis of thrombotic disease.

Experimental infection of three indigenous breeds of sheep in Nigeria, namely the West African Dwarf (WAD), Yankasa and Ouda resulted in fatal disease with the Zinga Rift Valley Fever virus. Infected sheep of the three breeds responded by pyrexia within 24 h of infection, that lasted 6 to 7 days, but peaked between day 2 and 4 post-infection. Viraemia coincided with pyrexia and peaked (10(9) PFU/ml) 3 days p.i. in Yankasa and WAD sheep, but with highest titre (10(7.5) PFU/ml) in Ouda sheep. Zinga Rift Valley Fever virus infection of sheep was characterised by hyperactivity, watery and mucoid nasal discharges, projectiles and bloody diarrhoea, external haemorrhage and clinical manifestations of nervous disorders. Viraemia was followed by low level of antibody development in all the infected sheep. Haemotological changes included a sharp fall in the PCV, Hb concentration and total RBC count during the course of the disease. These changes were most severe in the Yankasa, followed by WAD and Ouda breeds. There were thrombocytopaenia, prolongation of prothrombin and clotting times in all the infected sheep. There was also progressive leucopaenia associated with lymphopaenia. The total protein and albumin levels were depressed, but the globulin level rose from day 5 p.i. The changes in the serum biochemical constituents included sharp and progressive increase in the level of alanine aminotransferase and aspartate aminotransferase. The sodium level decreased gradually while that of potassium was initially stable but later increased until the infected animals died. There was a significant increase in the level of blood urea nitrogen from day 3 p.i. that continued until the infected animals died. Gross and microscopic examinations of the carcasses of the infected sheep showed significant lesions in many organs, including disseminated intravascular coagulation.

Clinical, clinico-pathological and serological studies were performed in sheep experimentally infected with Babesia ovis. Acute babesiosis occurred in all the lambs infested with adult Rhipicephalus bursa ticks and in one lamb infested with the larvae. The rate of parasitaemia and the degree of anaemia were not correlated. Decrease in the packed-cell volume ranged from 30 to 40%. Parasitized erythrocytes were not observed to block capillaries in the brain, which explained the absence of nervous symptoms in acute babesiosis. The kidneys were the most severely affected organs, exhibiting acute glomerulonephritis. The lesions observed were suggestive of vascular alteration and vascular stasis, leading to anoxia of the tissues. A disseminated intravascular coagulation (DIC) syndrome was recorded in sheep infected with babesiosis. A marked increase in the enzymes of the transaminase groups, mainly aspartate aminotransferase (AST), was observed. Enzymatic changes (increases in AST, alanine aminotransferase (ALT) and lactic dehydrogenase (LDH) and decreases in sorbitol dehydrogenase (SDH), alkaline phosphatase (ALP) and malic enzyme (MEZ)), decreases in total proteins and albumin, and increases in urea and creatinine might reflect the degree of severity of the damage to the liver and kidney tissues. Most of the lambs (85%) that were infested with larvae, and all lambs infested with adult R. bursa ticks, reacted serologically to B. ovis antigen. The serological reactions following infestation with the larvae occurred much later than those following infestation with the adult stage. The lambs which were infested with larvae showed mild clinical reactions when challenged by infected R. bursa adults, as compared with the reactions to the challenge in naive control animals. The serological findings, in addition to the fact that one splenectomized lamb reacted to larval infestation with acute ovine babesiosis, show that the preimaginal stages of R. bursa can transmit B. ovis, usually causing a sub-clinical disease. It is suggested that infections derived from preimaginal ticks in the winter can preimmunize sheep for the subsequent more severe infections derived from adult ticks in the summer. Furthermore, in the absence of a reliable vaccine against B. ovis, grazing flocks in the enzootic regions should be exposed to the preimaginal stages during their activity period (October-February) before exposure to the adult ticks in spring and summer (April-July).

We have attempted to determine whether depressed plasma plasminogen and alpha2 plasmin inhibitor (or alpha2 antiplasmin) activity is, as a result of consumption coagulopathy, a specific finding of disseminated intravascular coagulation (DIC) in septic patients. The hemostatic parameters of 139 septic patients (68 with DIC and 71 without DIC) were analyzed. Among the group as a whole, plasma activities of plasminogen and alpha2 plasmin inhibitor were significantly depressed in septic patients with DIC relative to those without DIC (P < 0.01 and P < 0.05, respectively). Notably, a significant correlation was observed between plasma levels of albumin and plasminogen activity, as well as between plasma levels of albumin and alpha2 plasmin inhibitor activity both in septic patients with DIC and those without DIC. However, no significant correlation was observed between plasma levels of plasmin-alpha2 plasmin inhibitor complex (PIC) and plasminogen activity, nor between PIC and alpha2 plasmin inhibitor activity either in septic patients with DIC or those without DIC. We concluded that depressed activity of plasminogen or alpha2 plasmin inhibitor is not as a result of consumption coagulopathy, but rather a result of low synthetic function of the liver in septic patients with DIC.

We investigated whether depressed plasma antithrombin and protein C activity, considered as a specific finding of disseminated intravascular coagulation (DIC), is due to consumption coagulopathy in septic patients with DIC. An analysis of hemostatic parameters was performed in 139 septic patients (68 with DIC and 71 without DIC). Plasma activity of antithrombin and protein C tended to be significantly decreased in septic patients with DIC but not in those without DIC (p < 0.001). However, when the septic patients were classified into three groups according to the albumin (or choline esterase) level, no significant differences in antithrombin activity or protein C activity were observed between the patients with and without DIC in any of the subgroups. Notably, neither the plasma activity of antithrombin nor protein C was decreased even in septic patients with DIC who had normal plasma levels of albumin (or choline esterase). No significant correlation was observed between plasma levels of thrombin-antithrombin complex (TAT) and antithrombin activity, or between plasma levels of TAT and protein C activity either in septic patients with DIC or without DIC. It is reasonable to conclude that the markedly reduced plasma activity of antithrombin and protein C is not due to consumption coagulopathy in septic patients with DIC.

Dengue virus infection can cause a wide spectrum of illness. Thrombocytopenia with concurrent haemoconcentration differentiates dengue haemorrhagic fever from classical dengue fever. Only cases with shock or unstable vitals signs need admission in the pediatric intensive care. The management is essentially supportive and symptomatic. The key to success is frequent monitoring and changing strategies. A rise in hematocrit of 20% along with a continuing drop in platelet count is an important indicator for the onset of shock. Patients in grade I and II should be closely monitored for signs of shock. The management of dengue shock syndrome (grade III and IV) is a medical emergency needing prompt and adequate fluid replacement for the rapid and massive plasma losses through increased capillary permeability. Early and effective replacement of plasma losses with plasma expanders or fluid and electrolyte solutions results in a favourable outcome in most cases. The ideal fluid management should include both cystalloids and colloids (including albumin). Cystalloids are given as boluses as rapidly as possible, and as many as 2 to 3 boluses may be needed in profound shock. Colloidal fluids are indicated in patients with massive plasma leakage and in whom a large volume of cystalloids has been given. Frequent recording of vital signs and determinations of haematocrit are important in evaluating the results of treatment. Apart from correction of electrolyte and metabolic disturbances, oxygen is mandatory in all patients of shock. Some patients develop DIC and need supportive therapy with blood products (blood, FFP and platelet transfusions). Polyserositis, in the form of pleural effusion and ascitis, are common in cases of dengue shock syndrome, and if possible, drainage should be avoided as it can lead to severe hemorrhages and sudden circulatory collapse. The prognosis depends mainly on the early recognition and treatment of shock.
