Four cases of intravascular coagulation associated with a state of acidosis in diabetics were observed in 57 patients with diabetic acidosis and 19 with lactic acidosis, in a series of 112 cases of consumption coagulopathy admitted to a department of medical resuscitation. In three cases the coagulopathy was found only on investigation; in one there were clinical and anatomic signs. The coagulopathy may be found either during the phase of recovery from ketoacidosis, or during the course of severe lactic acidosis, particularly during a recurrence of this form of acidosis. In spite of the unfavorable outcome in 3 of the 4 cases, the abnormal findings of coagulopathy reverted toward normal along with successful metabolic corrections. The factors responsible for consumption coagulopathy are acidosis, collapse, generalised systemic reactions and alterations of platelet function, of coagulation, of the balance between fibrin deposition and lysis and of lipid levels, all characteristic of diabetes. The clinical effects of this coagulopathy seldom become apparent but provide a possible explanation of some of the complications of diabetic ketoacidosis, particularly certain hemorrhagic or thrombotic events, as well as certain visceral complications, especially those affecting renal, pulmonary and cerebral areas.

A patient with chronic active hepatitis developed vomiting, dyspnoea, tachycardia, diarrhoea and diffuse pains. For several years she had been treated with azathioprine and for a few weeks before admission with phenformin for mild diabetes. Laboratory examination revealed acute disseminated intravascular coagulation and lactacidaemia. Despite intensive treatment the patient died a few hours after admission, the post-mortem examination revealing diffuse pulmonary haemorrhages. The present case report and those published in the literature suggest that phenformin should not be given to diabetics who also have renal or hepatic disease. In any case, if phenformin is given, it should be stopped if hepatic, renal, infectious or thrombotic complications occur. In these cases and those of sudden unexplained deterioration in diabetics, hospitalisation is essential and lactic acid levels should be determined and coagulation tests performed.

It has been reported that microangiopathic hemolytic anemia occasionally occurs in patients with severe diabetic microangiopathy. We report a case of insulin-dependent diabetes mellitus in whom microangiopathic hemolytic anemia and chronic disseminated intravascular coagulation (DIC) were thought to be complicated. The patient showed fragmentation hemolytic anemia and progressive diabetic microangiopathy, together with a mild elevation of serum fibrin(ogen) degradation products. Considering the state of chronic DIC, heparin therapy was started, but mild hemolysis persisted. It is possible that microangiopathic hemolytic anemia and chronic DIC cause a vicious cycle in patients with severe diabetic microangiopathy, leading to rapid progression of diabetic microangiopathy.

Circulating thrombomodulin is a novel endothelial cell marker, which may reflect the endothelial injury. Plasma levels of thrombomodulin were quantitated by an enzyme-linked immunosorbent assay (ELISA) in patients with hematological malignancies, liver disease, diabetes mellitus, collagen disease, thrombotic disease, and disseminated intravascular coagulation (DIC), and the thrombomodulin values were compared with those of von Willebrand factor antigen (vWf:Ag) and tissue-type plasminogen activator (t-PA) which are released from stimulated or damaged endothelial cells. The mean plasma concentrations of thrombomodulin in these disease states were elevated as compared with healthy subjects. A relatively high mean thrombomodulin level was observed in DIC, liver disease, and collagen disease. Abnormally high thrombomodulin values (greater than normal mean value + 3 SD) were found in 32.3% of patients with hematological malignancies, 57.7% of patients with liver disease, 39.3% of patients with diabetes mellitus, 30.0% of patients with collagen disease, 23.1% of patients with thrombotic disease, and 69.0% of patients with DIC. Plasma concentrations of both vWf:Ag and t-PA were also elevated in these patients. On the whole, the plasma thrombomodulin concentration was positively correlated with vWf:Ag (r = 0.441, P less than 0.001) and t-PA (r = 0.398, P less than 0.001). These findings indicate that the elevation of plasma thrombomodulin is frequently seen in a variety of diseases and circulating thrombomodulin is possibly useful for evaluating the endothelial damage in selected disease states.

A case of emphysematous pyelonephritis with disseminated intravascular coagulation (DIC) is presented. A 54-year-old woman was admitted to our hospital because of unclear consciousness and extremely high blood glucose level. The laboratory data suggested uncontrolled diabetes mellitus (DM) and urinary tract infection with sepsis and DIC. The plain abdominal X-P and abdominal CT revealed the existence of gas in the right renal parenchyma, perinephric tissue and the upper part of the right ureter. Right nephrectomy was performed after the improvement of the patient's condition by the echo-guided drainage of the right kidney and the treatment for infection, DM and DIC. We reviewed 71 cases of emphysematous pyelonephritis in the Japanese literature and the choice of treatment was discussed.

The pathophysiology of peripheral circulatory disturbance in patients presenting with vibration syndrome was studied from the viewpoint of blood coagulation. Plasma levels of fibronectin (FN), vitronectin (VN), thrombin-antithrombin III complex (TAT), and alpha 2-plasmin inhibitor-plasmin complex (PIC) were measured in 23 subjects who showed no evidence of vibration-induced white finger [VWF(-) group] and in 24 patients who presented with VWF [VWF(+) group]. In the VWF(-) group, plasma FN concentrations were elevated but plasma TAT and PIC levels were within the normal ranges. In the VWF(+) group, plasma FN concentrations were normal but plasma TAT and PIC levels were significantly elevated. In both groups, plasma VN concentrations were similar to those in normal controls. For purposes of comparison, 32 patients presenting with diabetes mellitus were also studied. They were divided into 2 groups, 13 subjects who showed no evidence of angiopathy [complication(-) group] and 19 patients who presented with angiopathy [complication(+) group]. In the complication(+) group, plasma TAT and PIC concentrations were significantly elevated, as in the VWF(+) group. These results suggest that in vibration syndrome, vibration, cold stimulus, or other factors first injure the vascular endothelium, resulting in a rise in plasma FN, and that in the VWF(+) group, augmentation of coagulation and fibrinolysis induces a state of compensated disseminated intravascular coagulation (DIC).

The safety of injecting discordant xenogeneic fetal endocrine pancreatic tissue into the portal vein was studied in a pig-to-dog system. It was found that minced fetal porcine pancreas and fetal porcine isletlike cell clusters prepared by collagenase digestion and culture could be injected with only minor or no hepatic hemodynamic disturbances. Coagulation studies revealed a small increase in plasma fibrinopeptide A, but this increase could be prevented by heparinization of the recipient. There was no consumption of fibrinogen or platelets. In contrast, injection of minced adult porcine pancreas caused pronounced hepatic hemodynamic changes and marked coagulation abnormalities, indicating consumption coagulopathy. The present finding that fetal porcine pancreas can be injected intraportally without deleterious effects in dogs provides a foundation for the eventual clinical use of such material as treatment for insulin-dependent diabetes mellitus.

In order to evaluate precisely the fibrinolytic states in clinical disorders, plasma levels of D dimer (cross-linked fibrin degradation products) were measured by a newly developed, rapid quantitative method based on the latex photometric immunoassay in patients with hematological malignancies, diabetes mellitus, collagen disease, liver disease, thrombotic disease and disseminated intravascular coagulation (DIC). Plasma levels of D dimer were elevated in a variety of diseases, especially in DIC. Patients with hematological malignancies, liver disease and thrombotic disease also had relatively high levels of D dimer. On the whole, D dimer values were positively correlated with plasmin-alpha 2-plasmin inhibitor complex and thrombin-antithrombin III complex. In addition, plasma D dimer was measured during fibrinolytic therapy with urokinase or tissue-type plasminogen activator; its elevation was detected in some patients. These findings indicate that accelerated fibrinolysis is frequently observed in a variety of diseases, and that a rapid quantitative measurement of D dimer would be valuable for the precise assessment of fibrinolysis in these disease states.

Chronic pancreatitis is difficult to treat in patients with a nondilated duct. Patients experiencing intractable pain unresponsive to or judged untreatable by lesser procedures must decide between total pancreatectomy and resultant diabetes or a continuation of their pancreatitis. From 1977 through 1990, 26 patients underwent extensive pancreatectomy and dispersed pancreatic islet tissue autotransplantation for treatment of chronic pancreatitis pain and prophylaxis of surgical diabetes. Of these 26 patients, total (Whipple) or near-total (greater than 95%) pancreatectomy was performed in 24 patients. Of these 24 patients, pain relief could be assessed in 21 patients at 5 to 155 months (mean, 5.7 years), and 19 patients (90%) reported partial or complete remission. Of the patients who underwent total or near-total pancreatectomy, islets were injected intraportally in 22 patients and into the renal subcapsule in two patients. The latter two patients have required insulin since surgery. Of the other 22, one patient died from a complication of the pancreatectomy. Nine of the 21 evaluable recipients of intraportal islet autografts were insulin independent for at least several months after surgery. Five patients are currently insulin independent at 6 years, 4 years, 1.5 years, 9 months, and 5 months after surgery. Of the other four patients, one patient died insulin independent at 6 years, and three patients required insulin beginning 8 to 18 months after surgery. Insulin independence correlated with the number of islets recovered, which in turn correlated inversely with the degree of pancreatic fibrosis. Of our four most recent patients, three patients had mildly to moderately fibrotic glands, and higher numbers of islets were obtained. After total (Whipple) pancreatectomy, these three patients are insulin independent. A liver biopsy was performed in one patient 8 months after total pancreatectomy and islet autotransplantation; numerous clusters of islet cells staining strongly for insulin and glucagon were detected within portal triads on both wedge and needle biopsy specimens. Morbidity related to the intraportal-dispersed pancreatic islet tissue transplantation was low (no disseminated intravascular coagulation, significant portal hypertension, or hepatic dysfunction). Islet autotransplantation can be an effective and safe adjunct to extensive pancreatic resection for those patients who risk surgical diabetes for relief of their chronic pancreatitis pain.

We analyze retrospectively all bacteremic episodes seen between January and December, 1987 in our institution. From a total number of blood cultures performed of 897, 145 were positive (16%), and 67 of them considered as contamination (7.5%). There were 78 episodes of bacteremia in 74 patients, 38 males and 36 females. Forty-eight episodes were community-acquired and 30 were nosocomial bacteremia episodes. Aerobic bacteria were isolated in 64 cases, anaerobic bacteria in 9 cases and polymicrobial bacteremia in 5 cases. The most commonly isolated microorganism was S. epidermidis in nosocomial cases and E. coli in community-acquired cases. Predisposing conditions registered were diabetes mellitus in 16 cases (20%), cirrhosis of the liver in 3 (4%), corticosteroid therapy in 7 (9%) and surgical procedures in 19 (24%). Shock was seen in 16 cases (20%), DIC in 8 cases (10%) and ARDS in 5 (6.5%). Appropriate antibiotic treatment was used in 60 episodes (77%). Seventeen patients (22%) died. Prognostic factors identified were: nosocomial bacteremia (p less than 0.05), corticosteroid prior therapy (p less than 0.05), underlying disease UF or RF (p less than 0.0001) and the presence of shock (p less than 0.0001). Mean hospital stay was 20.1 days in bacteremic patients vs. 7.6 days in non bacteremic patients (p less than 0.00001).
