Determination of platelet aggregation and disaggregation and the use of coagulogram indices reflecting the main stages of blood coagulation (the levels of fibrinogen and soluble complexes of fibrin-monomer, fibrinolytic activity) are recommended for the diagnosis of chronic DIC-syndrome in patients with diabetes mellitus. This syndrome is noted in diabetic patients before the development of clinical symptoms of microangiopathy but in parallel with microcirculatory disorders according to the results of conjunctival biomicroscopy. Platelet aggregation indices show correlation with the conjunctival index in diabetic patients even before the development of a clinical picture of diabetic retinopathy.

A case of emphysematous pyelonephritis is presented. A 66-year-old woman with diabetes mellitus was hospitalized for sudden pyrexia and left abdominal pain on January 13, 1987. She had shown preshock, pre-disseminated intravascular coagulation, hyperglycemia and renal dysfunction. Plain X-ray films of the abdomen and abdominal computer tomographic scanning showed a gas shadow in the left kidney. Retrograde pyelography demonstrated the left complete ureteral obstruction. A diagnosis was made of emphysematous pyelonephritis associated with diabetes mellitus and ureteral obstruction. Left nephrectomy was performed on January 17, 1987, and the pus obtained from the kidney yielded E. coli. After the operation, she has been doing well with diabetes mellitus under good control without insulin therapy. Thirty two cases of emphysematous pyelonephritis in the Japanese literature including our case are reviewed.

An autopsy case of clostridial gas gangrene occurring in a 54-year-old man with colon adenocarcinoma, liver cirrhosis, and diabetes mellitus is reported. The patient died 4 days after the onset of symptoms with episodes of vomiting and abdominal pain. Gangrene of both hips and perineum, hemolysis, renal failure, and disseminated intravascular coagulation were the dominant clinical features. Clostridium septicum was isolated from the subcutaneous tissue fluid. Adenocarcinoma of the ascending colon with ulceration found at autopsy was supposed to be an entry of the organism. Histologically, lesions of subcutaneous tissue and muscles were characterized by the absence of inflammatory infiltrates in spite of extensive necrosis. A summary of 35 cases of gas gangrene hospitalized to the Osaka University Hospital for the past 16 years indicates that clostridial gas gangrene patients with underlying diseases such as malignant neoplasm, diabetes, liver cirrhosis or immunodeficiency have a relatively poor prognosis.

In an effort to ascertain important epidemiologic and prognostic risk factors, we analyzed 33 cases of Staphylococcus aureus meningitis occurring over an 8-year period (1976 to 1984). Staphylococcus aureus caused 6% of all bacterial meningitis at our University Hospital. Fifty percent of cases were pediatric and included 7 newborn infants, of whom 71% were either premature or had low birth weight. Major underlying diseases were: central nervous system (CNS) disorders (55%), endocarditis (21%, predominantly intravenous drug abusers), other sites of infection (27%), and prematurity (24%). Fifty-seven percent of patients were bacteremic and 41% of those had concomitant bacteriuria. Hypoglycorrhachia was present in 27% of cases, positive cerebrospinal fluid (CSF) Gram stain in 20%, disseminated intravascular coagulation (DIC) in 19%, and methicillin-resistant organisms in 18%. Cerebrospinal fluid cultures remained positive for a protracted period (mean, 6.7 days) regardless of the presence or absence of a CNS shunt. Overall mortality was 21%. Favorable outcomes were associated with the eventual presence of sterile CSF (15.4% vs. 100% mortality) and the removal of foreign bodies (10% vs. 67% mortality). Mortality was also associated (p less than 0.5) with the presence of diabetes mellitus, age greater than 60, obtundation or coma on presentation, bacteremia, or DIC. Cure correlated (p less than .05) with CNS shunt-associated infections, age less than 1, normal neurologic examinations on presentation, or the absence of DIC or bacteremia.(ABSTRACT TRUNCATED AT 250 WORDS)

Overwhelming postsplenectomy infection (OPSI) due to group B streptococcus developed in an insulin-dependent diabetic patient. The illness began with nonspecific symptoms, followed rapidly by hypotension and disseminated intravascular coagulation. The early institution of appropriate antibiotics, fluid replacement and pressor agents resulted in a favorable clinical outcome. The association of group B streptococcal infection and diabetes mellitus is discussed. The defects in normal host defenses associated with asplenic state and diabetes mellitus are further emphasized. This is the first case report linking the association of OPSI, diabetes mellitus and group B streptococcal septicemia.

Six patients, ranging in age from 28 to 41 years, five men and one woman, underwent 80% to 95% pancreatectomy for chronic pancreatitis, with subsequent autotransplantation of pancreatic fragments. The technique for isolation of pancreatic fragments containing islets of Langerhans was extrapolated from previous experimental work. The follow-up period ranged from one to 25 months. Normal or near-normal carbohydrate metabolism was observed in each patient after the autotransplantation procedure; however, only two patients were insulin independent at 25 and 20 months. One patient died one month after pancreatectomy and autotransplantation of disseminated intravascular coagulation, and another died at three months of surgical complications and sepsis. The remaining two patients were alive and insulin dependent at nine and 25 months. Further developments in islet cell autotransplantation techniques are necessary to achieve, if possible, an insulin-independent status and avert surgically induced diabetes mellitus after total or subtotal pancreatectomy.

Thrombus formation depends on adherence of blood-formed elements to the intimal surface through platelet-vessel surface interaction, platelet release phenomena and aggregation, formation of fibrin, and the enmeshing of blood cells. Arterial thrombi involve platelet aggregation, whereas venous thrombi found in low flow or during stasis have greater proportions of erythrocytes and fibrin. It is not known if or how abnormalities of flow resistance, platelet thrombus formation, or endothelial and dynamic parameters affect the microcirculation, largely due to the difficulty of obtaining comprehensive data from these systems. Increases of fibrinogen observed in many disorders may result in minor changes in blood viscosity without known physiologic consequence, but in most disorders in which thrombosis is observed, the pathophysiologic mechanisms are multifactorial and abnormal blood viscosity is presumed to be a significant but not limiting component. Therapeutic approaches in thrombotic disorders should recognize which elements of the thrombotic triad predominate. In arterial disorders focus should be on platelet activity, and the objectives of venous thrombosis treatment include prevention of morbidity and death from pulmonary embolism, reduction of morbidity resulting from the acute thrombotic episode, and prevention of the postphlebitic syndrome. Pathology, mechanism, and treatment for specific thrombogenic disorders are described. Treatments suggested for hyperviscosity involve giving antibiotics during crises. Also discussed are thalassemia, paroxysomal nocturnal hemoglobinuria, polycythemia, cryoglobulinemia, paraproteinemia, diabetes mellitus, and disseminated intravascular coagulation. Studies have established a relationship between thromboembolic disease and oral contraceptives (OCs). The risk is only increased while the patient is taking OCs but is compounded in women undergoing surgery or who have a disorder which predisposes to venous disease. The risk for myocardial infarction or stroke is significantly increased when OCs are taken over age 35 and when there is hypertension, smoking, type-II hyperlipoproteinemia, and diabetes mellitus. The risk appears to be a function of estrogen dosage, causing a 25% mean increase in calf venous volume and 30% decrease in vein velocity of venous blood compared to controls. Low flow rates may contribute to venous thromboembolism. OCs may alter precisely regulated systems of coagulation and fibrinolysis and recent studies confirm abnormalities in the hemostatic system attributed to OCs. 16% of women taking OCs have a 60% or greater reduction in antithrombin III activity. The multiple effects of OCs often result in low-grade activation of the hemostatic system, potentially lowering the threshold to precipitate thrombus formation and possibly explaining the increased incidence of thromboembolic disease. Heparin appears to reverse many of these problems.

Diabetic coma is frequently associated with thromboembolic complications. A prospective study was undertaken of the haemostatic changes occurring in 15 patients (12 with ketoacidosis, three with the hyperosmolar syndrome) during diabetic coma. When compared with the results after stabilization of the diabetes, ketoacidosis was associated with significantly higher levels of factor VIII coagulant activity, factor VIII-related antigen and fibrin degradation products, a shorter partial thromboplastin time and reduced concentrations of antithrombin III. These results suggest that in uncomplicated ketoacidosis, haematological changes occur which may reflect vascular endothelial damage and intravascular fibrin deposition. Out of three deaths, two patients (both with the hyperosmolar syndrome) had evidence of disseminated intravascular coagulation. To reduce further the mortality and morbidity from diabetic coma, controlled clinical trials of anticoagulant and antiplatelet drugs may be indicated.

We describe a 62-year-old man with diabetes mellitus and peripheral vascular insufficiency, with an ulcer on his foot which led to staphylococcal septicemia, endocarditis, and disseminated intravascular coagulation. All these factors contributed to thromboembolic occlusion of the terminal arteries and veins supplying the stomach, causing gastric infarction.

Clinical features and specific aspects of treatment were evaluated in 612 patients with gram-negative bacteremia observed over a 10 year period. Coagulation abnormalities or thrombocytopenia were observed in 64 per cent of the patients. Evidence of disseminated intravascular coagulation (DIC) was found in approximately 10 per cent of them but was of sufficient severity to be associated with subcutaneous or visceral bleeding in 3 per cent of them. The frequency of coagulation abnormalities, other than DIC, was greater in patients with more severe underlying disease but DIC occurred with similar frequency irrespective of the severity of underyling host disease. Coagulation abnormalities of all types were associated with increased fatality rates. Hypothermia was noted in 13 per cent of the patients at the onset of bacteremia but was transient and was not associated with increased fatality. Failure to mount a febrile response greater than 99.6 degrees F within the first 24 hours of bacteremia was associated with a significant increase in fatality rates. Prior corticosteroid therapy diminished the febrile response to bacteremia. Age, underlying host disease, granulocytopenia, congestive heart failure, diabetes mellitus, renal insufficiency, nosocomial infections, and antecedent treatment with antibiotics, corticosteroids, and antimetabolites significantly increased fatality rates. Appropriate antibiotic treatment reduced the fatality rate of those with bacteremia by approximately one-half among patients in each category of severity of underlying host disease. In addition, it was shown that early appropriate antibiotic therapy also reduced the frequency with which shock developed by one half. Even after development of shock, appropriate antibiotic therapy significantly reduced fatality rates. The use of combinations of antibiotics could not be demonstrated to significantly improve survival rates. Minimal differences in therapeutic efficacy could be demonstrated between individual antibiotics and various combinations of antimicrobials. Shock occurred in approximately 40 per cent of the patients and its frequency was not influenced by the species of etiologic agent. Contrary to previous reports, corticosteroid therapy in patients with shock did not enhance survival and treatment with an average of 4.0 g/day of hydrocortisone or its equivalents was associated with a significant increase in fatality rates.
