Ceforanide, a new cephalosporin antibiotic with a long half-life (3 h), can be administered twice daily. We evaluated its antimicrobial activity, pharmacology, and clinical efficacy. Twenty-seven patients with infections due to susceptible organisms received ceforanide, 0.5, 1, or 2 g, intramuscularly or intravenously every 12 h for 6 to 28 days. In vitro studies with the clinical isolates from 27 patients treated plus 263 additional isolates showed that ceforanide was active against cephalothin-susceptible gram-positive and gram-negative microorganisms. In addition, ceforanide inhibited 65% of cephalothin-resistant Escherichia coli and 65% of Enterobacter spp. at </=12.5 mug/ml. After a single 1-g intramuscular dose, the mean peak plasma concentration at 1 h was 48.9 mug/ml and that at 12 h was 4.7 mug/ml. Plasma accumulation occurred in some patients. The infections included 10 pneumonias, 3 with bacteremia and 1 with empyema; 11 soft tissue infections, 4 with abscesses and 3 with sepsis; and 3 urinary tract infections. One case each of endocarditis, osteomyelitis, and septic thrombophlebitis, all due to Staphylococcus aureus, were treated. Clinical response was satisfactory in all patients; bacteriological response was satisfactory in 26 of 27 patients. Ceforanide was well tolerated. Three patients developed mild increases in liver enzymes, and one developed slight eosinophilia. In another case, the antibiotic was discontinued because of a fivefold rise in serum glutamic-oxalacetic transaminase (aspartate aminotransferase) and serum glutamic-pyruvic transaminase (alanine aminotransferase) and a twofold rise in lactic acid dehydrogenase and alkaline phosphatase.

Broadcillin 'Banyu', which contains an equal amount of ampicillin and oxacillin was given intravenously to children with acute bacterial infections and the following results were obtained. 1. Patients were 55 children with the following bacterial infections; respiratory tract infections (8 cases), pneumonia (34), sepsis (1), meningitis (1), cutaneous and subcutaneous suppurative inflammation (5), osteomyelitis (1), urinary tract infection (2), enteritis (1), and chemoprophylaxis (2). They ranged in age from newborns to 8 year old, but most of them were infants. In the majority of the patients, broadcillin 'Banyu' was administered 50 approximately 150 mg/day in three to four equally divided doses by one shot-injection or by a continuous drip infusion for a period of 2 approximately 10 days. The overall efficacy rate was 88.7% in 53 cases after two cases of chemoprophylaxis were excluded, i.e., excellent in 28, good in 19 and failure in 6: excellent in 4 and good in 4 in 8 cases of respiratory tract infections; excellent in 20, good in 11 and failure in 3 in 34 cases of pneumonia (an efficacy rate 91.2%); failure in sepsis and meningitis: excellent in 2 and good in 3 in 5 cases of cutaneous and subcutaneous suppurative inflammation; excellent in osteomyelitis; excellent in 1 and good in 1 of 2 cases of urinary tract infection; failure in enteritis. 2. Adverse reactions were noted on 10 occasions in 9 cases (16.4%), including 1 case of skin eruption, 1 case of eosinophilia, 5 cases of slight elevation of GOT, 1 case of slight elevation of GPT and 2 cases of slight elevation of BUN. 3. Based on the above results, it was concluded that clinical effect of broadcillin 'Banyu' by an intravenous administration is comparable to its intramuscular route and that safety of intravenous usage seems to be verified as long as the above described dosage is followed.

PC-904 was administered to 16 pediatric patients and the following basic and clinical results were obtained. (1) PC-904 was administered 20 approximately 30 mg/kg. The serum peak level of PC-904 after drip intravenous infusion over 1 hour was 66.7 microgram/ml at 1 hour and T 1/2 of PC-904 was 67.8 minutes. PC-904 was administered 25 approximately 30 mg/kg intravenous one shot injection was 49.4 microgram/ml at 1 hour and T 1/2 of PC-904 was 52.2 minutes. (2) Urinary excretion rate was about 20% up to 6 hours after drip intravenous infusion of 20 mg/kg. In a case of intravenous one shot injection of 25 approximately 30 mg/kg, the excretion rate was 11.9 approximately 19.9%. (3) PC-904 was administered 60 approximately 120 mg/kg/day for 3 approximately 48 days to 5 cases of sepsis and bacterial endocarditis, 6 of pneumonia, 2 of sss syndrome (staphylococcal scald skin syndrome) and 3 of pyelonephritis. Clinical effects were excellent in 11 cases and good in 5 cases, effective ratio being 100%. (4) Pseudomonas aeruginosa, Staphylococcus epidermidis, Streptococcus viridans, Acinetobacter anitratus and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904, and Hemophilus influenzae isolated from clinical specimens disappeared by the treatment of PC-904. Escherichia coli and Klebsiella pneumoniae reduced. (5) As to the side effect by PC-904, s-GOT and s-GPT were elevated in 2 cases. Anemia, rash and fever were observed in each 1 case out of 16 patients though the causal relation with the agent was unknown.

1. The hepatic metabolism of glutamine, alanine, ammonia, urea, glutathione and glucose was studied in rats made septic by caecal ligation and puncture and was compared with that in rats that had undergone sham operation (laparotomy). 2. Sepsis resulted in increases in the plasma activities of gamma-glutamyltransferase (P less than 0.001), alanine aminotransferase (P less than 0.001) and aspartate aminotransferase (P less than 0.001), the serum total and direct bilirubin concentrations (P less than 0.001), and the blood lactate (P less than 0.01), glutamine (P less than 0.05), alanine (P less than 0.001) and urea (P less than 0.05) concentrations, but produced decreases in the blood ketone body (P less than 0.001) and glutathione (P less than 0.05) concentrations and in the plasma cholesterol concentration (P less than 0.05). These changes were associated with marked negative nitrogen balance in septic rats. 3. Sepsis increased total hepatic blood flow (by 22.7%) together with hepatic arterial flow (by 25.8%) and portal venous flow (by 18.7%). Sepsis resulted in marked increases in the net rates of hepatic extraction of glutamine (by 164%), alanine (by 138%) and ammonia (by 259%) with concomitant increases in the net rates of hepatic release of glutamate (by 105%), glutathione (by 87.5%), glucose (by 70.1%) and urea (by 100.4%). 4. Sepsis increased the activities of liver carbamoylphosphate synthase (by 16.4%), ornithine transcarbamylase (by 29.8%), argininosuccinate synthase (by 28.1%) and arginase (by 33.8%). 5. Septic rats exhibited marked increases in hepatic protein (by 46.0%), RNA (by 43.4%) and DNA (by 37.7%) contents. These changes were accompanied by marked increases in the activity of thymidine kinase (by 35.9%).(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study is to evaluate the modifications in biochemical parameters before and after the initiation of nutritional therapy, and to observe whether there is a relationship between the patient's development (exitus or improvement) and the presence of sepsis. The study was performed on 578 adults treated in our hospital from January 1988 to October 1989. The parameters analyzed were the following: glucose, triglycerides, total proteins, albumin, cholesterol, alkaline phosphatase, GOT, GPT, bilirubin, GGT, urea, urates, creatinine and electrolytes. The average initial values of each parameter were compared against those obtained after interrupting the PN by means of the Student t test. The results showed that within the parameters indicating the hepatic function, GGT and alkaline phosphatase were those that showed the most significant differences after ceasing the PN. Furthermore, the parameters indicating hepatic function and the electrolytes showed greater variations, regardless of the clinical evolution of the patient (improvement or exitus). The remainder of the parameters showed significant variations based on the clinical evolution.

Eighteen immuno-compromised children (malignancies, hematological diseases, collagen diseases) with neutropenia and infections were treated with imipenem/cilastatin sodium (IPM/CS), and the efficacy and the safety of the drug were evaluated. 1. Responses to IPM/CS were excellent in 13 patients, good in 1, and fair in 4. None of the patients displayed a poor response to the treatment thus the efficacy rate was 77.8%. 2. Of 5 patients with sepsis, 4 had excellent or good responses. IPM/CS was effective against sepsis caused by Enterococcus faecalis and Pseudomonas aeruginosa. 3. In patients with severe neutropenia (WBC less than 100/mm3), the efficacy rate was 70%. 4. As for side effects, elevations of GOT and GPT were observed in 1 patient with liver cirrhosis. These results indicate that IPM/CS is safe and effective in immuno-compromised children with neutropenia and infections.

The placement of rubber band tourniquets upon rat hind-limbs for 5 h followed by reperfusion of the extremities results in a severe form of circulatory shock characterized by hypotension and death within 24 h of tourniquet release. Oxidative damage to muscle tissue is an early consequence of hind-limb reperfusion on tourniquet release, yet this local damage does not explain the lethal hypotensive shock state which evolves within the next 24 h. Multiple system organ failure (MSOF), of as of yet unknown causes, is usually described in relation to several shock states. It has been suggested that injured or necrotic tissue may activate neutrophils, platelets, and the coagulation system leading to embolization in remote tissues. Effective decreases in hepatic blood flow have been observed in several forms of sepsis which precedes the biochemical evidence consistent with an ischemic insult of the liver. In support of our original hypothesis, that organ failure has its genesis in a primary perfusion abnormality with secondary ischemic organ injury, herein we have assessed the possibility that oxygen-derived free radicals are generated in the liver of rats after reperfusion of their hind-limbs on release of the tourniquets. We report on the protective effects of allopurinol (ALLO) and a mixture of superoxide dismutase (SOD) catalase (CAT) and dimethylsulfoxide (DMSO) on liver free sulfhydryl content (SH), thiobarbituric acid-reactive substances (TBARS), and on the release of aspartic acid (AsT) and alanine aminotransferase (AlT) activities, and of alkaline phosphatase during a 5 h tourniquet period and after 2 h of reperfusion of the hind-limbs. During the hind-limb ischemic period hepatis tissue SH levels remained essentially constant during the first hour (6.02 +/- 0.36 to 5.65 +/- 0.20 mumoles/g wet tissue), and decreased significantly, over and above the normal circadian decrease of liver glutathione levels, to 4.02 +/- 0.69 mumoles/g wet tissue after the third hour and remained lowered until tourniquet release. A further significant decrease (3.11 +/- 0.49 mumoles/g wet tissue) was observed after 2h of reperfusion. TBARS production remained constant during the 5 h hind-limb ischemic period (168.4 +/- 37.3 mumoles/g wet tissue) and rose by 55% to 261.7 +/- 55.8 mumoles/g wet tissue after 2 h of tourniquet release. ALLO, but not the SOD-CAT-DMSO combination, protected hepatic SH loss during the hind-limb ischemic insult, yet both offered protection after 2 h of tourniquet release.(ABSTRACT TRUNCATED AT 400 WORDS)

Fifty patients with infections associated with hematological disorders were treated with ceftazidime (CAZ). Among them 44 cases were evaluable, including 21 with acute leukemia, 17 with malignant lymphoma, and 6 with other hematological disorders. Excellent responses were observed in 15 patients (34.1%) and good responses in 15 (34.1%), with an overall efficacy rate of 68.2%. The efficacy rate among sepsis and suspected sepsis cases was 67.6%. This treatment was also effective in 7 of 10 cases in which neutrophil counts were less than 500/mm3 through the course of administration. Laboratory abnormalities included mild eosinophilia in 1 case, slight elevation of GOT in 1 case and slight elevation of GPT in 1 case. These results suggest that CAZ is an effective and safe antibiotics for the treatment of infections in patients with hematological disorders.

We conducted clinical studies on panipenem/betamipron (PAPM/BP), a newly developed parenteral carbapenem antibiotic, for its clinical application in the field of pediatrics. 1. A clinical study was performed on 13 children with infections, including 6 with acute bronchopneumonia, 1 each with acute pharyngitis, acute bronchitis, sepsis, staphylococcal scalded skin syndrome, urinary tract infection, subcutaneous abscess and furuncle. PAPM/BP was administered by intravenous drip infusion. Doses varied from 12 to 27 mg/kg body weight were given t.i.d. or q.i.d. Lengths of treatment ranged from 4 to 25 days. Clinical efficacies were excellent in 3 and good in 9 cases, with an efficacy rate of 92%. 2. No adverse reactions were observed. In laboratory tests, elevations of GOT, GPT and urobilinogen were observed in 3 cases. It was concluded that PAPM/BP was a promising drug for the treatment of bacterial infections in children.

The purpose of this study was to test the hypothesis that different hepatocellular functions are regulated individually during sepsis. This was done by simultaneously measuring bile production, release of liver transaminases, and synthesis of secreted proteins in perfused livers from control and septic rats. Sepsis was induced by cecal ligation and puncture (CLP); control rats were sham-operated. After 16 hours, livers were perfused in situ, and bile flow, synthesis rates of albumin and alpha 1-acid glycoprotein (a major acute-phase protein in rats), and release of glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) into perfusate were determined. Within the same livers, sepsis resulted in a 54% increase in the synthesis of alpha 1-acid glycoprotein and approximately 30% inhibition of albumin synthesis concomitant with 50% lower bile flow. The concentrations of GOT and GPT in the perfusate increased slightly during the experiments, both when control and septic livers were perfused. The maintained tissue levels of adenosine triphosphate (ATP) and the uptake of Evans blue dye by less than 1% of the hepatocytes, although a late test of viability, suggest that both control and septic livers remained viable during perfusion. The results are consistent with the concept that different hepatocellular functions are individually regulated during sepsis. Thus, impairment of certain hepatocellular functions does not necessarily imply generalized liver failure.
