Liver injury is common in patients following hemorrhage and sepsis. There are multiple etiologies for this liver injury which involve both decreased nutrient blood flow and direct cellular injury. Enteral nutrients vasodilate gut blood vessels and increase blood flow to the intestines and liver. Since enteral nutrients vasodilate gut blood vessels, we wondered whether luminal nutrition would prevent hepatic injury during shock states. We randomized Sprague-Dawley rats to saline or enteral nutrition via duodenal feeding tubes. Animals were then subjected to 60 min of hemorrhagic hypotension or intraperitoneal injection of lipopolysaccharide (LPS). Liver injury was assessed by measuring levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) before and after hemorrhage or LPS. Enteral nutrients significantly decreased liver injury following hemorrhage. AST increased from 246 +/- 17 to 1605 +/- 593 U/L in saline animals and 283 +/- 39 to 551 +/- 94 U/L in enterally fed animals. ALT increased from 60 +/- 4 to 726 +/- 355 U/L in saline animals and 61 +/- 6 to 161 +/- 38 U/L in enterally fed animals. Enteral nutrients did not significantly alter the increase in AST/ALT following LPS. These results indicate that enteral nutrients can decrease liver injury following hemorrhagic hypotension.

Cefozopran (CZOP, SCE-2787), a new parenteral cephem, was evaluated for its antibacterial activity and clinical efficacy. CZOP, 24.0-78.0 mg/kg/day, was given to 11 pediatric patients in 3 dose a day via 30-minute drip infusion. Clinically evaluated were nine patients including 4 with acute pneumonia, 2 with urinary tract infections, 2 with lymphadenitis and 1 with sepsis. Two patients were excluded because of possible non-bacterial infections. Clinical efficacies were excellent in 5, good in 3 and fair in 1. Bacteriological responses were confirmed for 5 strains in 5 patients. Four strains were eradicated, but one strain was not. MICs of CZOP were equal to those of ceftazidime. Side effects or abnormal laboratory test results were observed in 3 patients; diarrhea in 1, elevated GPT in 1 and thrombocytosis in 1, but none of them was significant.

Cefozopran (CZOP) was administered via intravenous injection to 9 patients (ages ranging from 1 month to 13 years) with pediatric bacterial infections, at daily dose levels between 56.7 and 200 mg/kg, divided into 3 or 4 doses. The following results were obtained. 1. Eight patients, including 1 with purulent meningitis, 1 with sepsis, 3 with acute pneumonia and 3 with lymphadenitis, were treated and subjected to clinical evaluation. Clinical effects were excellent in 6 cases and good in 2, with an overall efficacy rate of 100%. One case with pyoderma was not evaluated because of a combined use of an external antibiotic. 2. Organisms suspected as pathogens included 5 strains: 3 strains of Haemophilus influenzae, 1 strain of Staphylococcus aureus and 1 of Escherichia coli. Bacteriologically, all the strains were eradicated. 3. Side effects or abnormal laboratory test results were observed in 4 cases; wheal in 1 case, elevated GOT and GPT in 2 cases and eosinophilia in 1 case. 4. From the results described above, we considered that CZOP would be an effective drug for use in pediatric bacterial infections.

We studied the clinical efficacy of biapenem (L-627), a new parenteral carbapenem beta-lactam antibiotic in the pediatric field. L-627 was administered intravenously to 11 patients with ages ranging 2 months to 10 years and 5 months with acute infectious diseases. Doses ranged 28.1 to 72.6 mg/kg/day. The diagnosed diseases included 7 respiratory tract infections, 1 purulent meningitis, 1 sepsis, 1 cervical lymphadenitis and 1 urinary tract infection. Two of these cases one with Mycoplasma infection and the other which had been administered with other antimicrobial agents were not evaluated. The clinical efficacy rate was 77.8% (7/9) and the bacteriological eradication rate was 66.7% (4/6). Laboratory examinations revealed that there was one case with elevated liver enzyme levels with showing elevation of GOT, GPT and LDH. No other side effects attributable to this drug were observed. Thus, it appears that L-627 is a useful antibiotic in treating moderate to severe acute bacterial infections in children.

We investigated the clinical efficacy of arbekacin (ABK) in patients with methicillin-resistant Staphylococcus aureus (MRSA) infections, and also studied coagulase types, beta-lactamase producing activity and drug sensitivity of MRSA isolated from various clinical specimens. A total of 23 patients with MRSA infections (13 cases of pneumonia, 1 case of sepsis, 1 case of pneumonia and sepsis and 8 cases of the others) who were hospitalized from April 1992 to September 1993 were enrolled in this study. They were 14 males and 9 females, and the mean age was 66.9 years (range, 18-91 years). All patients had underlying diseases (mainly malignant tumors and cerebrovascular diseases). ABK was given intravenously at doses ranging from 75 to 100 mg twice daily. The clinical efficacy rate was 90%; 8 cases showed excellent responses, 10 cases good, 1 case fair, 1 case poor and 3 cases were unevaluable. The eradication rate of MRSA was 81.8%; 16 cases were judged as eradicated, 3 cases decreased, 2 cases replaced, 1 case unchanged and in 1 case the bacteriological response was unknown. Side effects were not observed, but S-GPT was elevated in 1 case. Coagulase types of MRSA (123 strains) isolated at the institutes involved in the study were type II (56 strains), type IV (12 strains), type VII (13 strains) and other types (2 strains), but coagulase types of 40 strains could not be determined. Eighty-four strains (68.3%) produced beta-lactamases. MICs of ABK were 0.5 microgram/ml against 43 strains and 1 microgram/ml against 37 strains, and all of the MICs were under 4 micrograms/ml. In summary, ABK showed high antimicrobial activity against MRSA and clinical usefulness in the infections investigated.

The efficacy, safety and usefulness of murine anti-endotoxin monoclonal IgM antibody "E5, an intravenous dose of 2 mg/kg" were evaluated in 88 patients with suspected Gram-negative sepsis from 37 institutes in Japan. Out of these, 74 patients were evaluable for the efficacy, 85 for safety and 75 for clinical usefulness. In assessing the efficacy, the patients were divided into 3 groups based on the plasma endotoxin levels (Endospecy with new PCA treatment of plasma): H group with a level of above 9.8 pg/ml and M group with a level of 3.0-9.8 pg/ml and L group with a level of below 3.0 pg/ml. 1. The efficacy rates as assessed following administration of E5 were 73.1% in the H group, 70.4% in the M group and 38.1% in the L group being higher in the groups with significantly high plasma endotoxin levels. 2. In both the H and M groups in whom plasma endotoxin levels were significantly high, the majority of the patients showed rapid reduction of the levels after administration of E5. 3. In all groups, improvement in body temperature, pulse rate, blood TNF-alpha and blood IL-6 was observed after treatment with E5. In the H and M groups with an endotoxin level of > or = 3.0 pg/ml, improvement in platelet count as well as in CRP was noted. The H group showed also improvement in WBC. 4. Improvement in the shock score was noted in all the groups but was more outstanding in the H and M groups in the early stage of treatment. 5. Side effects were seen in 5 (5.9%) of 85 patients and all thought to be allergic in symptoms such as rash, itching, fever and flare. 6. The reaction to the prick test performed before administration of E5 was negative in all these 5 patients. For 3 of the 5 patients, anti-E5 IgE antibody was measured. In all of them, the IgE levels were higher than those of healthy controls. Also, in 47.6% of patients, an elevation of anti-E5 IgG antibody was noted two weeks after the administration. 7. Clinical laboratory abnormalities were observed in 3 (3.5%) of 85 patients. They were an elevation of S-GOT.S-GPT and lowering of BUN, increased Al-p and decreased CH50, increased neutrophilia (%) and were all slight in the degree of the changes. 8. The clinical usefulness of E5 was evaluated for 75 patients.(ABSTRACT TRUNCATED AT 400 WORDS)

The aim of this retrospective study was to determine whether total parenteral nutrition-related liver disease was improved by intravenous antibiotics given for systemic sepsis. Liver function tests were performed 1 month before, during and 1 month after one episode of sepsis treated for 4 weeks (mean, range: 2-12), with systemic antibiotics, in 12 patients receiving parenteral nutrition for 13 months (mean, range: 1-71) for short bowel syndrome in 10 of them. Cholestatic liver disease appeared in all during nutrition (mean serum alkaline phosphatase activity > 4 N). Liver test abnormalities observed at the beginning of antibiotics treatment were not significantly different from those observed 1 month before sepsis. Antibiotic administration was followed by a significant decrease (P < or = 0.03) in serum activities of alkaline phosphatases, ALT and AST and bilirubinemia of 38, 41, 23 and 47%, respectively. These results support the concept that parenteral nutrition-associated cholestatic liver disease may be related to intestinal bacterial overgrowth and suggest that it may be improved by intravenous antibiotherapy.

Multiple organ dysfunction (MOD) is the leading cause of mortality in septic patients with circulatory shock. Recent evidence suggests that the overproduction of the cytokine, tumor necrosis factor-alpha(TNF), and oxygen free radical molecules may mediate the progression of sepsis to MOD and death. In this study, we have examined the ability of MDL 101,002, a free radical scavenger, to reduce organ dysfunction and cytokine secretion induced by lipopolysaccharide (LPS) administration in rats. Treatment with MDL 101,002(10-60 ng/kg, i.p.) 30 min prior to an LPS challenge resulted in a dose-dependent reduction in several markers indicative of organ dysfunction and mortality. MDL 101,002 markedly decreased LPS-induced liver and kidney damage as indicated by serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) or urea and creatinine, respectively. MDL 101,002 also prevented LPS-induced pulmonary edema, but did not prevent leukopenia and only partially reduced thrombocytopenia. Associated with these improvements in organ dysfunction and survival was a modest decrease in LPS-stimulated interleukin-1 alpha (IL-1 alpha) and interleukin-1 beta (IL-1 beta) secretion and a marked ( > 90%) inhibition of TNF secretion by MDL 101,002. The data are consistent with a role for oxygen free radicals in the development of endotoxin-induced organ dysfunction and shock and suggest that free radical scavengers could reduce the mortality consequent to sepsis by decreasing organ dysfunction, at least in part, through a reduction in free radical stimulated cytokine secretion.

Interleukin-1 (IL-1), a cytokine released from macrophages by endotoxin stimulation, has been shown to upregulate the genetic expression of the hepatocyte growth factor (HGF). The present study was conducted to determine whether plasma HGF is increased in patients with systemic inflammatory response syndrome (SIRS). The plasma levels of HGF, endotoxin, and beta-glucan were measured in 41 surgical patients without hepatic diseases, 18 of whom had been diagnosed with sepsis, and 33, with nonseptic SIRS. The plasma HGF was found to be significantly increased in the 18 patients with sepsis, at 0.69 +/- 0.47 ng/ml (mean +/- SD), and in the 23 patients with nonseptic SIRS, at 0.49 +/- 0.37 ng/ml, compared to values in 40 normal controls, at 0.10 +/- 0.03 ng/ml (P < 0.001). No significant correlations were observed between the plasma levels of HGF and endotoxin (r = 0.02) or beta-glucan (r = -0.05) in any of the patients; however, plasma HGF was significantly correlated with the WBC count (r = 0.34, P < 0.05) and with total bilirubin (r = 0.45, P < 0.01). Plasma HGF was also strongly correlated with alanine transaminase (ALT) in 8 patients with ALT levels higher than 50 U/l (r = 0.70), but there was no such correlation in 33 patients with ALT levels of 50 U/l or less (r = 0.30). Thus, although the clinicopathologic significance of HGF is not well understood, the present findings indicate that plasma HGF increases in response to infection or inflammation.

Streptococcus pneumoniae is an uncommon etiological organism in hemolytic uremic syndrome (HUS). Production of neuraminidase by S. pneumoniae results in exposure of red blood cell T-antigen, resulting in hemolysis, thrombocytopenia, and acute renal failure. Hepatic involvement in this form of HUS has not been described in the literature. We report in three children with S. pneumoniae-associated HUS the presence of severely elevated transaminases and conjugated hyperbilirubinemia. Increases in asparagine transaminase ranged from 11 to 46 times normal values and an increase in alanine transaminase ranged from 1.6 to 8 times normal. In all patients the rise in total bilirubin was 7-15 times normal. Biliary tree obstruction and viral causes for liver dysfunction were absent. Hepatocellular injury in S. pneumoniae-associated HUS likely results from mechanisms involved in sepsis and pneumonia-induced jaundice, combined with severely increased bilirubin production following massive hemolysis. The hepatic injury in all three patients resolved within 9, 5, and 10 days. Our experience suggests that an extensive evaluation including liver biopsy is not indicated.
