Therapeutic effects of dopamine hydrochloride on the peripheral and metabolic defects of shock were investigated in 34 patients with circulatory shock associated with myocardial infarction, bacteremia, or hypovolemia. Severity of the circulatory defect characterized by hypotension, reduced cardiac output, oliguria, and notably reduced skin (toe) temperature before treatment with dopamine was not directly related to survival. However, the arterial blood concentration of lactate before treatment with dopamine indicated the likelihood of survival. Patients who ultimately survived following treatment with dopamine had normal or only mildly elevated levels of arterial blood lactate before therapy. No patients with established shock states in whom perfusion failure was associated with substantial increases in the level of arterial blood lactate survived regardless of treatment with dopamine. Increases in toe temperature during dopamine treatment also emerged as a uniquely good indicator of favorable outcome during therapy.

To investigate three possible causes of the acute hemolysis in the hemolytic-uremic syndrome, we studied prospectively 207 children and 34 adults with shigellosis in Bangladesh. Nineteen children showed acute hemolytic anemia, a leukemoid reaction, thrombocytopenia and oliguria; nine other had, in addition, a serum urea nitrogen level of over 100 mg per diciliter. Eight of the nine had pseudomembranous colitis, and six of the nine died. The frequency of bacteremia was similar in all grades of shigellosis. Circulating immune complexes were found in 10 of 20 patients with uncomplicated shigellosis and in four of six with severe hemolytic-uremic syndrome. Limulus assay for endotoxemia was positive in nine of 18 patients with hemolysis (50 per cent) and three of 61 with uncomplicated shigellosis (5 per cent) (P less than 0.001). These data support the hypothesis that severe colitis in shigellosis is associated with circulating endotoxin from the colon producing coagulopathy, renal microangiopathy and hemolytic anemia.

Over a period of 6 years 192 cases of urosepsis have been recorded and managed in our urological department. In almost all cases (97%) the primary focus of infection was the urinary tract and the responsible microorganisms were Gram-negative rods, in order Enterobacter, B. Proteus, E. Coli, Klebsiella and others. Clinical features were dominated by symptoms related to failure or insufficiency of end organs (fever, hypotension, oliguria, mental disorders, respiratory distress etc.). Bacteremia was diagnosed with an incidence of 66%, septic shock 12% and MSOF 20%. Negative bacteriological tests do not rule out the diagnosis of systemic infection. Risk factors are considered advanced age, uremia, diabetes, malnutrition and extensive surgery.

The energy metabolism of kidney and renal function were studied in rats following an IV injection of living Escherichia coli. Energy charge (ATP + 0.5 ADP/ATP + ADP + AMP) decreased throughout the period studied. Total and ouabain-sensitive Na-K ATPase activity of renal cortex homogenate decreased markedly at 3 hr followed by gradual recovery. Polyulia was seen at 3 and 6 hr followed by oliguria at 12 hr after E. coli injection. PSP excretion test showed a marked decrease throughout the time course. In contrast, creatinine clearance decreased only at 12 hr. From these results, it was clarified that the renal insufficiency following bacteremia occurs in two different stages; the early stage with a high urinary output accompanied by decreased Na-K ATPase activity suggesting deterioration of proximal tubular functions and the late stage with oliguria in which glomerular filtration is severely depressed. In both stages, renal energy metabolism is markedly disturbed.

Seventeen episodes of persistent Staphylococcus epidermidis bacteremia (one to nine days) occurred in 16 patients with vascular catheters during a 26-month period. Cases were statistically more likely to have a longer hospitalization (54 v 7.6 days, p less than .0005), longer duration of antibiotic therapy (22 v 2.5 days, p = .002), presence of a central venous pressure (CVP) catheter (14 v 2, p less than 3 X 10(-8), and presence of an arterial catheter (4 v 1, p = 0.037) than randomly selected hospitalized patients matched for age, sex, and date of admission. However, when cases were compared with similarly matched non-bacteremic patients having CVP catheters, these characteristics were not significantly different in the two groups. Furthermore, exposure to total parenteral nutrition (TPN) and duration of TPN were not significantly different between cases and controls. Hence, the presence of a CVP catheter appeared to be the major risk factor for S. epidermidis bacteremia. In 16 episodes, patients had temperature greater than 38.6 degrees C without another identifiable cause, and the average white cell count for the case group was 19,400/mm.3 Seven patients also had diaphoresis, confusion, hypotension, or oliguria. Temperatures returned to normal in 13 within 24 hours after catheter removal, and all patients were afebrile and symptom-free within 72 hours. Thus, vascular catheter-associated S. epidermidis bacteremia was an important case of febrile morbidity in these patients.

The syndrome of sepsis-associated severe acute renal failure is a frequent component of sepsis-induced multiorgan failure. Continuous hemofiltration techniques are often used in its dialytic management but little is known about their impact. The aim of this study is to define the biochemical and clinical impact of continuous hemodiafiltration (CHD) in the management of this syndrome and to retrospectively compare it to that of conventional dialysis. A prospective, cohort study and retrospective comparison with historical controls was conducted at an intensive care unit (ICU) of a tertiary institution. Eighty-seven consecutive septic patients with acute renal failure were treated by continuous hemodiafiltration and 40 consecutive similar patients by conventional dialysis. All new cases of severe acute renal failure with sepsis were treated by means of continuous hemodiafiltration. Historical controls were treated by means of conventional dialysis. Illness and sepsis severity were assessed on admission and prior to initiation of treatment. Biochemical variables were assessed daily. Outcome was measured as discharge from the ICU, duration of oliguria and discharge from hospital. Of the 87 patients treated by hemodiafiltration, 86 had multiorgan failure, 71 (81.6%) septic shock and 52 (59.8%) bacteremia/fungemia. Their APACHE II score on admission was 29.9 and their mean organ failure score prior to treatment was 4.3. Hemodiafiltration resulted in a significant fall in mean urea and creatinine levels within 24 h and in the correction of acidosis. The mean alveolar-arterial gradient fell from 276 to 211 mm Hg (p < 0.02) within 24 h of therapy. Complications were few and mostly related to vascular access.(ABSTRACT TRUNCATED AT 250 WORDS)

Five episodes of fungemias are described; all had occurred in children with leukemia or lymphoma between January 1, 1978 and December 31, 1990. These fungemias comprised 3.4% of the total septicemias encountered during that period. Three episodes occurred during the induction phase and two during relapse. All patients had fever of varying degree and duration. In addition to steroids, all were receiving combination antibiotics before the fungemia had occurred. All patients had severe neutropenia lasting more than one week. Bacteremia preceded fungemia in four patients. Two episodes were diagnosed antemortem. The same species were isolated from other sites in three cases. Fever, chills and gastrointestinal symptoms were the most common clinical features; other symptoms included cough, dyspnea, oliguria and azotemia. One patient experienced skin lesion, dysphagia, hoarseness and hemiparesis. Only one patient survived. The prognosis from fungemia in leukemia and lymphoma patients is very poor. Empiric antifungal therapy is indicated in neutropenic patients who have recurrent or persistent fever despite one week of broad spectrum antibiotics. Early diagnosis and treatment will aid in improving the overall poor outcome of this disease.

From 1982 to 1994, 45 patients (1.22 episodes per 10,000 discharged patients) were treated for citrobacter bacteremia at National Taiwan University Hospital (Taipei). All patients had at least one underlying disease. Citrobacter bacteremia most commonly occurred in patients with malignancies (48.9%) or hepatobiliary stones (22.2%). Intraabdominal tumors comprised the majority (59.1%) of malignancies. Bacteremia commonly originated from sites such as the abdominal cavity (51.1%), urinary tract (20%), and lung (11.1%). Polymicrobial bacteremia was diagnosed in 15 patients (33.3%); for nine (60%) of these patients, the source of the infection was intraabdominal. Prior treatment with a third-generation cephalosporin was significantly associated (P < .01) with the development of multidrug resistance among the isolates. The mortality associated with citrobacter bacteremia was 17.8%. Poor prognostic factors included pneumonia, altered mental status on presentation, hypothermia, oliguria, septic shock, deterioration in mental status, hyperbilirubinemia, azotemia, and thrombocytopenia. Combination therapy, as compared with other regimens, improved the outcome of citrobacter bacteremia.

Septic shock may be defined as hypotension caused by bacteremia and accompanied by decreased peripheral blood flow, evidenced by oliguria. Clinically, a shaking chill is the warning signal. The immediate cause of hypotension is pooling of blood in the periphery, leading to decreased venous return: later, peripheral resistance falls and cardiac failure may occur. Irreversible shock is comparable to massive reactive hyperemia. Reticuloendothelial failure, histamine release, and toxic hypersensitivity may be factors in the pathogenesis of septic shock. Adrenal failure does not usually occur, but large doses of corticosteroid are employed therapeutically to counteract the effect of histamine release or hypersensitivity to endotoxin. The keys to successful therapy are time, antibiotics, vasopressors, cortisone and correction of acidosis.

We have reported two orthopedic patients with Methicillin-resistant Staphylococcus aureus (MRSA) infections successfully treated with linezolid. The first case was a 64-years-old man with bacteremia, spondylitis and psoas abscesses caused by MRSA. He was treated with arbekacin (ABK) and vancomycin (VCM), and then became afebrile. However he complained of a recurrence of fever and oliguria, we administered linezolid for two weeks intravenously because of fluctuating renal dysfunction. Thereafter his clinical conditions improved. The second case was a 26-years-old man with MRSA infection of the pelvis after a trauma. He was treated with teicoplanin (TEIC) for two weeks. However the minimum inhibiratory concentrations (MICs) of TEIC and VCM against MRSA, isolated from the wounds, were 4 micrograms/ml each, we administered linezolid intravenously and the patient was successfully treated in four weeks. Linezolid has been proven to have high efficacy against MRSA by some trials abroad. But the agent has the indication only for VRE by the Medical Insurance in Japan. These cases also suggest that linezolid is useful for MRSA infections in these cases.
