Thirty-eight patients who had sustained acute trauma, profound hemorrhagic shock, and massive transfusion were studied prospectively to determine the predominant etiologic factors in the development of post-traumatic jaundice. An analysis of clinical and biochemical factors occurring in association with each bilirubin peak in the postoperative course found the jaundice related to transfusion and surgery in 11 instances, to sepsis and septicemia in 15 instances, and to hepatic dysfunction in 23 instances. Results indicated that admission estimates of SGOT and LDH levels, the height of the bilirubin peak and the postoperative day on which it occurs, and the white cell count and GGT at the time of the peak may be of use in the differential diagnosis. Four case reports were used to emphasize the fluctuating pattern of jaundice and the different etiologic factors that may predominate. Light and electron microscopy from three patients illustrated the structural alterations that accompany the biochemical impairment of liver function and enable a more precise appreciation of this syndrome. Hepatic dysfunction appears to be implicated in a high proportion of patients who develop post-traumatic jaundice, which frequently occurs as part of a spectrum of multiple organ failure.

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)

This paper presents further preliminary results of a trial of the prophylaxis of sepsis in 165 patients undergoing vascular surgery. The efficacy and safety of a single dose of teicoplanin was examined and compared with three doses of cephradine plus metronidazole. No significant differences were detected in the prophylactic efficacy in either group. The first interim report indicated abnormalities in liver function, maximum at 7 days, in both groups. These findings are confirmed in this second interim report. Raised levels of GGT and alkaline phosphatase are more prominent in patients receiving teicoplanin. Liver function improved by 28 days, however, suggesting that any abnormality is transient.

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.

In order to elucidate the frequency of hyperbilirubinemia associated with sepsis in the elderly, as well as in clinical and histological characteristics, a total of 117 autopsy cases with sepsis were analyzed retrospectively. Based on the clinico-pathological findings, 48 cases with primary hepato-biliary, cardiac, hematological and shock complications, were excluded because these disorders were thought to affect liver function tests. Four cases out of the remaining 69 cases, 5.8% of the total, showed hyperbilirubinemia above 2 mg/dl (average 4.1 mg/dl), which was thought to be associated with sepsis itself. In these 4 cases, disproportionately high levels of blood total bilirubin were characteristic compared to changes of GOT, GPT, LDH, ALP and gamma-GTP levels. Blood culture of these 4 cases revealed Gram-negative organisms in 3 cases and Gram-positive in 1 case. Histological findings of the liver included cholestasis, Kupffer cell hyperplasia and cell infiltration in the sinusoid and portal areas, however these findings were mild and nonspecific. It is important to recognize the presence of hyperbilirubinemia associated with sepsis in order to properly treat febrile elderly patients with hyperbilirubinemia.

To establish the potential value of quantitative tests of liver function following orthotopic liver transplantation (OLT), a total of 100 determinations of caffeine clearance (CafCl) and galactose elimination capacity (GEC) were made in ten OLT recipients early in the post-operative course (days 2, 4, 6, 8 and 12) and later when clinically stable (3-12 months). Values were compared with a reference range in six normal volunteers in whom it was shown that the standard doses of caffeine (125 mg) and galactose (0.5 g per kg body weight) could be given together without interference. In orthotopic liver transplantation recipients initial GEC and CafCl measurements showed no correlation with peri-operative blood loss, donor ischaemia time, initial bile flow or survival. Throughout the early post-operative period, there were wide inter- and intra-individual variations in both CafCl (17-fold range from 0.16 to 2.7 ml.min-1.kg-1) and GEC (2.4-fold range from 5.1 to 12 mg.min-1.kg-1), but the only correlation of test values with standard liver function tests results was between GEC and gamma-glutamyltranspeptidase. However, GEC values fell by 19% during periods of acute rejection and there was an inverse correlation of GEC with white cell count probably related to sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abnormalities in biochemical liver function tests in 127 general surgical patients who had a course of intravenous nutrition have been reviewed. Only 26 patients had liver function tests considered to be normal on commencing intravenous nutrition and they were included in this retrospective study. During intravenous nutrition the most sensitive biochemical test of liver dysfunction was gamma-glutamyl transpeptidase--all patients having an elevated gamma-glutamyl transpeptidase level by week 4. Most abnormalities were transient whereas the elevation of alkaline phosphatase was prolonged beyond week 9. Patients with major sepsis were found to have almost double the incidence of abnormal liver function test values compared with patients with no evidence of sepsis. Only patients who were transfused more than 8 units of blood showed a significant rise in bilirubin. Liver function tests in patients who received smaller transfusions showed no difference from patients who did not receive any blood. Patients with below normal anthropometric measurements on commencing intravenous nutrition were more likely to develop abnormalities in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and gamma-glutamyl transpeptidase.

An evaluation is made of liver malfunctions in patients receiving TPN over a period of > or = 15 days between 1989 and 1991. Use was made of the monitoring records on patients undergoing TPN and, subsequently, of clinical records, with analysis of diagnoses and type of intervention, the biochemical parameters (SGOT, SGPT, GGT, FA, LDH, and total and direct bilirubin), and the type and degree of malnutrition, nutritional backup, associated medication, etc. A group of patients was excluded from the study on the basis of the following criteria: liver-biliary disease, cardiac insufficiency, liver metastasis, sepsis, kidney insufficiency and hepatotoxic drugs. Of 237 patients, 75 (31.64%) had liver alterations: following application of the exclusion criteria, 24 patients (10.12%) were taken with liver alterations attributable to the TPN. Macro- and micronutrients were included in the TPN. We found no relation between the kcal/kg of weight, nor with the quantity of glucose and fats nor of nitrogen, calculated according to individual requirements: they remained within the limits established. No serious case of cholestatic jaundice was encountered. Moderate to severe malnutrition was found in 50% of patients, so that this must be treated as a risk factor. GGT is the first enzyme to alter; this occurred in the largest proportion of patients (91.66%), followed by SGPT. FA and GOT are altered in the same percentage of patients. Biochemical parameter monitoring is essential in patients undergoing TPN, not only for appraisal of the nutritional state but also to prevent or correct potential serious metabolic complications.

Progressive liver failure in parenteral nutrition (PN)-dependent children with short bowel syndrome carries significant morbidity and mortality. The authors retrospectively reviewed 47 consecutive patients with short bowel syndrome diagnosed from October 1985 through October 1995. All patients were treated according to a protocol designed to promote intestinal motility and discourage bacterial translocation. Elements of the protocol included the use of taurine, vigilant prevention and aggressive treatment of sepsis, meticulous catheter care, early PN cycling, appropriate enteral feeding, and measures designed to inhibit gastrointestinal bacterial translocation, especially gram-negative rods. Complete blood counts and serum liver function studies were compiled from both clinic visits and hospital admissions for each patient every 3 to 6 months while they were on PN. Three patients were lost to follow-up after they had moved out of state. The length of time on PN ranged from 3 months to 9.4 years with an average of 2.2 years. Elevated aspartate aminotransferase (AST), alanine aminotransferase (ALT), and glutamyltransferase (GGT) were present in 82%, 66%, and 84% of patients, respectively. Alkaline phosphatase was elevated in 58% of patients. Eight patients (18%) are still on PN, and 31 (70%) have been weaned off PN. Five patients have died (11%). Three patients (7%) developed cholecystitis requiring cholecystectomy. No patients developed progressive liver failure. These results suggest that PN-related liver failure may be prevented in most patients with short bowel syndrome. Specific measures to prevent PN-related cholestatic jaundice need further investigation.

From 1984 through 1992, staff at The Marine Mammal Center (TMMC, Sausalito, California, USA) examined 207 northern elephant seals (Mirounga angustirostris) with a condition of unknown etiology called northern elephant seal skin disease (NESSD). The skin lesions were characterized by patchy to extensive alopecia and hyperpigmentation, punctate or coalescing epidermal ulceration, and occasionally, massive skin necrosis. Microscopic lesions included ulcerative dermatitis with hyperkeratosis, squamous metaplasia and atrophy of sebaceous glands. All diseased seals were less than 2 years of age and suffered from emaciation, depression, and dehydration. Mortality from septicemia increased significantly with severity of skin ulceration. Compared to 14 apparently unaffected seals, diseased seals had depressed levels of circulating thyroxine, triiodothyronine, retinol, serum iron, albumin, calcium, and cholesterol. Levels of alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, gamma glutamyl transpeptidase, blood urea nitrogen, and uric acid were elevated. Morphometrically, diseased animals were approximately 15% smaller than normal seals of the same sage. Serum and blubber concentrations of 36 polychlorinated biphenyl congeners (sigma PCB) and dichloro-diphenyl-dichloroethylene (p,p'-DDE) were negatively correlated with body mass. Mean concentrations of sigma PCB and p,p'-DDE in serum in diseased seals were elevated as compared to apparently normal seals. Etiology of this syndrome remains unknown, but the possibility of PCB toxicosis cannot be ruled out.
