In ten experiments, 53 castrated male 4- to 8-week-old weanling pigs were given adriamycin (ADR) IV at mean dosages of 0.64, 1.0, 1.6, 3.2, or 6.4 mg/kg/week at various frequencies for up to 20 weeks. Mortalities in pigs given these dosages were 0% after 112 days, 100% after 134 days (survival time was 48 to 134 days), 91% after 75 days (survival time was 5 to 75 days), 100% after 28 days (survival time was 23 to 28 days), and 100% after 14 days (survival time was 10 to 14 days), respectively. Survival time was prolonged in younger pigs and in pigs given smaller but more frequent dosages of ADR. Characteristic gross and histopathologic alterations of ADR toxicosis were observed in pigs given 1.0, 1.6, 3.2, or 6.4 mg/kg/week mean dosages. The most frequent lesions were in the alimentary tract, myeloid and lymphoid tissues, skin, and perivascular tissues at injection sites. Alimentary tract lesions were mucosal epithelial atrophy, with secondary fibrinonecrotic inflammation in the oral cavity and large intestine. Marked hypoplasia was seen in bone marrow and lymphoid tissues, with frequent terminal hemorrhagic diathesis and septicemia. Several days before death, the pigs developed severe dermatitis over the ventral portion of the abdomen and inner surfaces of the limbs. Perivascular necrosis and cellulitis produced by extravasation of ADR was a frequent complication of treatment. Terminal severe acute pneumonia occurred in most pigs. Pericarditis or cardiomyopathy (or both) developed in 14 pigs, given 0.64, 1.0, or 1.6 mg/kg each week (mean cumulative dosage 520.5 mg/m2 of body surface). Characteristic histopathologic and ultrastructural alterations in affected cardiac muscle cells were vacuolar degeneration, myocytolysis, and hyaline necrosis. Nephrotoxicosis also was in pigs with chronic ADR toxicosis. Systemic antibiotic treatment did not prolong survival of ADR-treated pigs in two experiments, but did in one other experiment.

The treatment of disseminated intravascular coagulation (DIC) in infants with sepsis should be instituted after multimodality therapy of pyo-inflammatory diseases taking into account the degree of hemostatic disorders. In stage I DIC (hypercoagulation one), it is necessary to reach an adequate level of the inhibitors of the thrombin and plasmin systems. In this case it is quite sufficient to use donor's cryoplasma without heparin administration. In stage II DIC (transitory one) and stage III (hypocoagulation one), it is required that the drugs possessing antithrombin and antiplasmin activity, substitution therapy with blood preparations and components as well as measures to control hemorrhagic diathesis may be used.

Critical conditions had been established in 21 (23.1%) of 91 patients with systemic connective tissue diseases for a 12 year period: renal failure (most often), sepsis, pericarditis with cardiac tamponade, hemorrhagic diathesis, terminal arteritis with gangrene, gastrointestinal perforations with peritonitis, etc. The corticosteroids applied in high doses and predominantly parenterally and the immunosuppressors are the main drugs used in the treatment of these conditions. Plasmapheresis when possible is a useful supplement. The prognosis of the acute critical conditions depends mainly on the affected organ (more favorable in pericarditis with tamponade and unfavorable in renal failure and gastrointestinal perforations with peritonitis (and on the basic disease) more optimistic in systemic lupus erythematodes and very pessimistic in nodal periarteritis and other allergic vasculitis).

Septicemia is frequently accompanied by changes in the plasmatic as well as cellular coagulation systems and by microclot formation. The occurrence of a hemorrhagic diathesis and microthrombosis is best explained by the syndrome disseminated intravascular coagulation (= consumption coagulopathy). Disseminated intravascular coagulation can be initiated by different agents and by different pathways. The activation of coagulation by endotoxin is well studied; it is mediated by synthesis of tissue factor by monocytes and endothelial cells. The formation of microthrombi is caused by the precipitation of circulating soluble fibrin under the influence of localizing factors, and it is observed under conditions of reduced fibrinolysis activation. Furthermore, thrombocytopenia, thrombocytopathy and endothelial cell damage caused by a direct effect of the toxic agent contribute to the bleeding diathesis.

Based on autopsy findings in 301 adults who had died after intensive care, different patterns of single or multiple organ damage were identified. Signs of septicemia and/or exudative-to-fibrosing alveolitis (EFA) of the lungs, the prominent cause of the adult respiratory distress syndrome (ARDS), were recognized in 89 cases. Severe, progressive EFA, which appears to ensue mainly from continuing damage to alveolar walls, consequent fibroblast proliferation and so-called atelectatic induration (collapsed alveoli forming single thick septa), was registered only in individuals who had undergone long-term intensive care. The latter was necessitated in various severe conditions of which abdominal disease was the most important. Systemic disorders, such as hemorrhagic diathesis and multiple organ damage ("multiple organ failure"), showed a close correlation with septicemia. Infections with gram-negative bacteria appear to play a special role in such processes. Morphologically, these cases were characterized by multiple organ/system damage, e.g., in order of frequency, partial necrosis of renal proximal tubules, followed by signs of regeneration; jaundice; splenitis; lobular pneumonia; centrolobular-to-zonal liver necrosis, in part combined with cholestasis; petechial and/or extended hemorrhage; and others. This complex pattern contrasted strongly with findings in individuals who had been admitted to intensive care because of e.g. a cardiovascular incident: in this latter group (125 cases) intensive care was usually of short duration, progressive EFA was largely absent, signs of septicemia were exceptional, and multiple organ/system damage was rare. The group with polytraumatism (28 cases) exhibited a pattern of organ damage intermediate between (a) and (b).

Continuous renal replacement modalities have found widespread use and acceptance over the last decade. The various modalities differ in the kind of access (arteriovenous v venovenous); in the application of convective clearance (continuous hemofiltration), diffusive clearance (continuous hemodialysis), or a combination of both (continuous hemodiafiltration); and in the location where the replacement fluid enters the circuit (predilution v postdilution). Continuous therapies incorporate several advantages, such as improved hemodynamic stability, the possibility for unlimited alimentation, optimal fluid balance, and gradual urea removal without fluctuations. However, it has not yet been shown whether these advantages have a significant impact on outcome and prognosis, the ultimate measure of treatment efficiency. Major disadvantages of continuous therapies are the ongoing necessity for continuous anticoagulation, immobilization of the patient, and possible side effects from lactate-containing replacement fluid or dialysate. Continuous renal replacement procedures have certainly made the management of critically ill patients easier. In particular, oligoanuric patients with diuretic resistant volume overload and hemodynamically unstable patients with acute renal failure and concomitant sepsis or multiorgan failure appear to benefit most from continuous treatment. The role of continuous hemofiltration as a method of removing serum cytokines in septic patients without renal failure is still controversial and needs further clinical assessment. Due to slow efficacy, continuous renal replacement is indicated only in rare circumstances for intoxication; this therapy also is of rather limited use in severe hyperkalemia or acidosis. Noncritically ill patients with uncomplicated renal failure (eg, due to the use of dye or antibiotics) should be treated with intermittent hemodialysis or peritoneal dialysis. Furthermore, intermittent hemodialysis is preferable in patients with hemorrhagic diathesis because it can be easily performed without anticoagulants.

The bleeding syndrome of acute promyelocytic leukemia (APL) is complex and consists of disseminated intravascular coagulation (DIC) and hyperfibrinolysis. Elastase, derived from malignant promyelocytes, is believed to mediate the fibrinogeno- and fibrinolysis by aspecific proteolysis. In this study we measured the role of elastase in fifteen patients with APL by using an assay for elastase degraded fibrin(ogen) and the results were compared with those obtained in patients with sepsis induced DIC. High levels of elastase were observed in sepsis and APL. The levels of fibrinogen and fibrin degradation products were significantly higher in APL patients compared to patients with sepsis induced DIC. Nevertheless, the level of elastase degraded fibrin(ogen) was higher in the sepsis group (635.3 ng/ml, compared to 144.3 ng/ml in APL; p <0.0001). So, the enormous increase in fibrin and fibrinogen degradation products in APL cannot be explained by elastase activity. This study suggests a minor role for elastase mediated proteolysis in the hemorrhagic diathesis in APL patients.

53 of 3100 abortions at Bombay hospital were septic abortions, giving an incidence of 1.7%. Various factors of possible etiological significance were analyzed, including age, parity, marital status, duration of gestation, and the mode of interference leading to sepsis. 36 of 53 patients were aged 20-30 years, but other age groups were represented. In the present study, gravidity was not relevant, for all gravidity groups, from primipara to grand multipara 5 and above, had patients suffering septic abortions. 9 patients were married and gave a history of interference; in all, 38 patients were married, 22 were unmarried, and 4 were widows. 23 patients gave a definite mode of interference, and the most common method was interference with a stick. 43% mortality occurred in patients giving a history of interference, and 36% mortality occurred in others. Vaginal and cervical cultures revealed (16 cases studied) 5 cases of CL. tetani, 1 case of E. coli, and 10 patients showing strepto-, staphylo-, pneumococcal infections. In this series, 21 of 53 patients died: 8 of tetanus, 3 or renal failure, 4 of septicemia, 2 of hemorrhagic diathesis, and 3 of endotoxic shock. 1 patient had acute bacterial endocarditis and pulmonary embolism at sutopsy. It is this article's contention that the main cause of sepsis is using an instrument to induce abortion during an unwanted pregnancy; hence, a plea is made for more liberalized abortion legislation.

Disseminated intravascular coagulation (DIC) is an extremely serious hemorrhagic disorder and one that is potentially lethal. DIC is more frequently observed as a complication of obstetric pathologies, diffused neoplasms, bacterial sepsis, blood transfusions, traumas and adipose embolias. The literature reports very few cases occurring after total hip replacement, two of which the cause of death. In all of the cases described one or boh prosthetic components are cemented. The authors report a case observed after total hip replacement in a patient submitted one year previously to contralateral hip replacement. Severe hypotension, bradychardia and profuse bleeding of the wound and from the drainages one hour after suturing constituted the initial symptom. Recognition of the clinical findings, after exclusion of a iatrogenic lesion, and subsequent treatment in intensive therapy allowed us to save the patient. The syndrome must be suspected and immediately diagnosed when profuse bleeding that cannot be related to vascular lesion is observed immediately postsurgery after cemented or hybrid hip replacement. Confirmation through hematological tests and timely treatment in a specialized center are indispensable requirements to save the life of the patient.

Severe systemic manifestations of adult onset Still's disease (AOSD) are often fatal and occasionally related to hemophagocytic syndrome (HS). We describe the case of a 49-yr-old woman with AOSD presenting with non-remitting high fever, confusion, jaundice, hepatosplenomegaly, serositis, azotemia, pancytopenia, coagulopathy with disseminated intravascular coagulation (DIC), hyperferritinemia, acute acalculous cholecystitis and ileocolitis noted in computed tomographic images. The patient had a history of herpes zoster developed prior to the admission, but there is no history of diarrhea or abdominal pain. Although bone marrow examination was not performed due to hemorrhagic diathesis, we suspected AOSD-associated HS on the basis of clinical course without detectable infectious agents in cultures or serologic studies. Intravenous immunoglobulin, pulse methylprednisolone, oral cyclosporine A (CsA) and ceftriaxone brought about transient improvement of fever and confusion, but the disease progressed. After increasing CsA dose, all previously mentioned abnormalities disappeared rapidly. Accordingly, we believe that DIC and multiple organ dysfunctions might have been the complications of HS but not that of sepsis, and that CsA can be used as a first-line therapy in case of life-threatening situations.
