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.

To determine whether or not kinin activation in the blood during severe infection with gram-negative bacteria may be related to hemodynamic abnormalities encountered, blood prekallikrein, kallikrein inhibitor and kinin values in 2l surgical patients with sepsis were compared with those in normotensive and hypotensive states. Because of reduced prekallikrein synthesis in patients with hepatic insufficiency, the normotensive and hypotensive groups were each subdivided according to the presence or absence of liver dysfunction, as indicated by elevated blood bilirubin, serum glutamic-oxalacetic transaminase or alkaline phosphatase levels. The mortality was zero in group 1, normotensive normal liver function; 80 per cent in group 2, hypotensive-normal liver function; 20 per cent in group 3, normotensive liver dysfunction, and 67 per cent in group 4, hypotensive liver dysfunction. Ultimately, the majority of deaths were due to respiratory failure. Although the blood prekallikrein level, was below normal in all groups and was significantly less in all patients with liver dysfunction, it was reduced proportionately in hypotensive patients to less than 30 per cent of the values noted in the two normotensive groups. This finding suggests prekallikrein consumption in the hypotensive groups to be the result of the process of activating kallikrein and bradykinin. This concept is supported by finding elevated kinin values, above 3 nanograms per milliliter of plasma, in only 28 per cent of those in group 1 and 12 per cent of those in group 3, while in the hypotensive patients, groups 2 and 4, the kinin level was elevated in 60 and 66 per cent, respectively.

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 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.

We have previously shown the safety and efficacy of University of Wisconsin solution for hypothermic preservation of the human donor heart in a pilot group of 16 transplant recipients. The present study is a randomized clinical trial comparing University of Wisconsin solution to conventional preservation using crystalloid cardioplegia and saline storage within a 4-hour limit of ischemia. Heart transplant recipients (n = 42) were randomized into two groups: those receiving hearts preserved by University of Wisconsin solution, the UWS group (n = 22), and those receiving hearts preserved in the conventional manner, the CCS group (n = 20). Recipient age, gender, heart disease, and preoperative inotropic support and donor age, gender, and mean ischemic time in hours (UWS 2 hours 36 minutes, range 1 hour 36 minutes to 2 hours 53 minutes; CCS 2 hours 20 minutes, range 1 hour 20 minutes to 2 hours 44 minutes; p = not significant) were similar. Significant differences observed between the two groups included (1) mean time (minutes) from reperfusion to achieve a stable rhythm, (2) need for intraoperative defibrillations, (3) need for transient cardiac pacing, and (4) integrated postoperative creatinine kinase and aspartate aminotransferase release over 48 hours. There was no difference in postoperative electrocardiogram, endomyocardial biopsy, or hemodynamics. One UWS patient died of sepsis and another of a ruptured cerebral aneurysm. UWS is safe for donor organ arrest and preservation despite high viscosity and potassium concentration. When compared with CCS hearts, hearts preserved in UWS regained electrical activity more rapidly and had better myocardial protection as demonstrated by enzymatic analysis. Further investigation is required to determine the effects of UWS preservation on long-term survival, to determine the prevalence of rejection and graft atherosclerosis, and to test the ability of UWS to extend donor ischemic time in human cardiac transplantation.

Hepatic dysfunction is a frequent finding in sepsis and peritonitis. In the present study, hepatic function in experimental peritonitis in the rat was determined by measuring serum levels of bilirubin, alkaline phosphatase (ALP), glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT), together with antipyrine (AP) clearance as a determinant of microsomal function. Peritonitis was induced by intraperitoneal injection of 3 x 10(8) colony-forming units of E. coli together with either 1.0 ml bile or saline. E. coli + bile peritonitis rats had significantly elevated levels of bilirubin, ALP, GOT and GPT as compared with both controls and rats with peritonitis induced by E. coli alone. The derangements gradually increased with time over the 10-hour period studied. In contrast, no reduction of AP clearance was observed in the peritonitis models. On the contrary, AP clearance was enhanced at 10 hours after induction of peritonitis by E. coli alone. In conclusion, hepatic dysfunction as revealed by routine laboratory tests is seen early in experimental peritonitis in the rat, but this is not accompanied by a reduced AP clearance rate.

A 5-year prospective study was performed to monitor liver function tests (LFTs) in patients receiving total parenteral nutrition (TPN). A gradual and progressive rise was seen in the plasma concentration of bilirubin, aspartate transaminase, and alkaline phosphatase. The rate of rise was not increased in patients with LFT abnormalities before the start of TPN. Half of the patients had an episode of sepsis during TPN, but overall abnormal LFTs did not appear more common in these patients than in those without obvious sepsis. Patients with malignant disease, those requiring long-term TPN, and those requiring a nonstandard TPN regimen were more likely to develop raised LFTs.

Sixteen patients with massive bowel resection receiving long-term home total parenteral nutrition (HTPN) for 31 to 145 months were reviewed for evidence of liver disease. Patients were divided into three groups: group 1 with duodenocolostomy (n = 3), group 2 with an estimated 15-43 cm residual small bowel (n = 7), and group 3 with an estimated 55-120 cm residual small bowel (n = 6). Two patients in group 1 developed liver cirrhosis; one was diabetic and died of sepsis and liver failure at the 88th month on HTPN; the other died of lung cancer at the 46th month on HTPN. The third patient, followed for 33 months, had transient severe liver function abnormalities associated with a blood transfusion. In groups 2 and 3, only one patient (with a history of probable liver disease before HTPN) developed biopsy-proven cirrhosis at the 60th month of HTPN. All four patients with clinically apparent liver disease developed persistent elevation of serum aspartate aminotransferase (AST) early in HTPN. Four other patients (all in group 3) with abnormal AST values in the early phase of HTPN normalized them later; they did not develop clinical liver disease over a mean follow-up time of 110 months (range, 39-152). None of the remaining eight patients (seven in group 2 and one in group 3) had significant liver function test abnormalities and none developed clinical liver disease over a mean follow-up period of 72 months (range, 39-120).(ABSTRACT TRUNCATED AT 250 WORDS)

The preliminary results of a trial to examine and compare the safety, tolerability and efficacy of a single dose of teicoplanin with three doses of cephradine combined with metronidazole are presented in a series of 113 patients undergoing elective vascular surgery. There were no obvious differences in the infection rates and sepsis indicators in either group. Neither drug regimen produced any evidence of renal or hepatic damage, though the levels of three hepatocellular enzymes, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl-transferase (GGT), were seen to be transiently elevated, peaking 7 days post-operatively. The trial continues.

Scarcity of small donors results in a high mortality rate for children on liver transplant waiting lists. To alleviate this problem, we have recently started to reduce the size of livers from older donors to use in children. In the last year, a total of 20 liver transplants were performed in 17 patients, including seven reduced-size liver transplants (RSLT) in six children. Mortality on the waiting list has been reduced to negligible amounts compared with a mortality rate of 25% before starting RSLT in patients with acute liver failure or those whose weight was less than 10 kg. Children undergoing RSLT weighed 10.8 +/- 8.5 kg compared with 20.9 +/- 20.3 for all others (NS). Cold ischemia time was significantly longer in the RSLT group (9.5 +/- 3.0 v 6.0 +/- 2.8 hours, P less than .05) as was intraoperative blood loss (9.4 +/- 9.4 v 3.0 +/- 3.5 blood volumes). There was no significant difference in postoperative aspartate aminotransferase and prothrombin time between the two groups. Four children received a RSLT as a primary procedure and three have survived with good liver function. Two patients were retransplanted with RSLT after a failed first transplant and both died of nonhepatic complications. This compares with 11 of 13 survivors in the whole liver transplant group. Causes of death in children who died after RSLT include cytomegalovirus sepsis (2) and myocardial infarction(1).(ABSTRACT TRUNCATED AT 250 WORDS)
