Recovery of liver functions following surgical biliary decompression in obstructive jaundice.

BACKGROUND/AIMS: Derangement of liver functions in obstructive jaundice has been known to influence surgical outcome. The pattern and time frame of liver function recovery in patients with surgical obstructive jaundice undergoing a bilioenteric anastomosis has not been comprehensively defined in human beings. METHODOLOGY: Fifty patients of obstructive jaundice who underwent a bilioenteric anastomosis had their liver function evaluated done by biochemistry (pre-operatively and postoperatively on day 1,4,7 and 6 weeks) and radionuclide mebrofenin scan (preoperatively and 6 weeks postoperative). RESULTS: The results have shown a constant and significant decline in serum bilirubin levels by day 4 (p=0.04), however the decline in serum levels was not uniformly progressive in 54% patients. The decline in serum alkaline phosphatase levels has been constant and progressive reaching significant levels by day 4(p=0.01). Serum transaminases showed an initial rise followed by a rapid fall, again achieving significant levels by day 4 (p=0.003 & 0.009). Serum albumin decreased on day 1 itself but remained static after that. On isotope scanning hepatic uptake showed uniform improvement with 92% of patients having achieved a normal uptake after 6 weeks. Gastrointestinal excretion of the isotope however was still delayed in 26% patients at 6 weeks. Almost all these patients had an abnormal bilirubin level decline in the immediate postoperative period. CONCLUSIONS: Hepatic functional recovery has been seen to start immediately following bilioenteric anastomosis and has usually completed itself by 6 weeks. Patients who show an abnormal recovery pattern based on bilirubin levels need to be observed for a longer time.

Evidence for a substantial genetic influence on biochemical liver function tests: results from a population-based Danish twin study.

BACKGROUND: Biochemical liver function tests are widely used in the clinic and are some of the most frequently used tests in screening for diseases in older age groups. The aim of the present study was to estimate the relative importance of genetic and environmental factors to variations in these tests among the elderly. METHODS: We conducted a survey among Danish twins, 73-102 years of age, identified in the population-based Danish Twin Registry. Among the 2749 individuals in the study population, an interview was conducted with 79%. From these, a blood sample was collected from 290 same-sex twin pairs, total of 580 subjects, within a 6-month period and analyzed for alanine aminotransferase (ALT), lactate dehydrogenase (LDH), gamma-glutamyltransferase (GGT), bilirubin, and albumin. The interview included questions about alcohol consumption and body mass index (BMI; self-calculated height and weight). Heritability (proportion of the population variance attributable to genetic variation) was estimated using structural-equation analyses before and after correction for alcohol consumption and BMI. RESULTS: Structural-equation analyses revealed a substantial heritability (35-61%) for the four biochemical liver function tests: ALT, GGT, LDH, and bilirubin. The remaining variation could be attributed to individuals' nonfamilial environments. Adjustment for alcohol consumption and BMI had no influence on the heritability for ALT, GGT, LDH, and bilirubin. For albumin, two models fit equally well before adjustment for alcohol and BMI: a model including additive genetic and nonshared environmental factors (AE), and a model including shared and nonshared environmental factors (CE). After adjustment, the model including shared and nonshared environment was clearly the best fitting model. CONCLUSIONS: For both males and females, the effect of genetic factors on the biochemical liver function tests ALT, GGT, LDH, and bilirubin is substantial and accounts for one-third to two-thirds of the variation among individuals 73-102 years of age. The heritability is equal for males and females and does not change notably after controlling for alcohol consumption and BMI. For albumin, no major impact of genetic factors was found independent of BMI and alcohol consumption. An understanding of the genetic mechanisms underlying biochemical liver function tests among the very old may be of value in the interpretation of these tests in this age group.

Evaluation of subjective assessment of liver function from radionuclide images.

The appearance of non-hepatic uptake in 99Tcm-colloid images is an important indicator of poor liver function. We undertook this study to evaluate the ability of experienced observers to assess liver function from radionuclide images. A simple model was used to simulate the changing distribution of 99Tcm-colloid in the liver, spleen and bone marrow as the liver function and mass were varied. Suitable images of these three organs were isolated from real studies and used as "templates" to create realistic simulated 99Tcm-colloid images, with the count densities of liver, spleen and bone marrow determined by the model. These images were presented in random order to several observers, who were asked to assess liver function. Comparison of the estimated with the true function shows that visual assessment is systematically inaccurate, with underestimation of poor function and overestimation of good function. It is also imprecise, especially for livers with only midly impaired function. Observers were also affected by changing liver mass and were more likely to judge small livers to be abnormal. We suggest that objective assessment using a quantitative technique should be used as an adjunct to visual inspection for the evaluation of liver function.

How are abnormal results for liver function tests dealt with in primary care? Audit of yield and impact.

OBJECTIVE: To determine whether abnormal results for liver function tests are investigated in primary care and findings on full investigation. DESIGN: Retrospective audit and prospective clinical investigation. SETTING: University hospital and surrounding general practices serving around 330 000 people. SUBJECTS: Adults with abnormal results for liver function based on tests requested by their doctor between 1 January and 30 June 1995. INTERVENTIONS: All patients with gamma-glutamyltransferase, alanine aminotransferase, or alkaline phosphatase concentrations at least twice the upper limit of the reference range were studied. A median of 15 months later (range 12-21) records of hospital attendances and further investigations were examined. Where investigations were incomplete the records from the general practice were examined, and suitable patients were invited to attend the liver clinic. MAIN OUTCOME MEASURES: Investigations requested by the doctor and final diagnoses reached. RESULTS: 933 patients with abnormal liver function tests were identified; follow up data were obtained in 873 (94%). 531 patients were already under hospital review. Of the remaining 342 patients, 157 were suitable for investigation; the others had died, moved away, were elderly, or had repeat liver function tests with normal results. No further tests were requested for 91 (58%) of these patients. 66 had been partially investigated by their doctor, and in seven patients results suggesting a treatable chronic liver disease had not been followed up. On investigation, 97 (62%) had an identifiable diagnosis requiring hospital intervention or follow up, or both. CONCLUSIONS: Abnormal results for liver function are often not adequately investigated, missing an important chance of identifying treatable chronic liver disease.

[The echo-guided interstitial laser photocoagulation of malignant liver tumors. The authors' personal technic, immediate results and short-term complications in patients with normal and altered liver function].

PURPOSE: The literature studies about interstitial laser photocoagulation of liver tumors mainly deal with the treatment of liver metastasis in patients with normal liver function. We report our personal experience with interstitial laser photocoagulation in patients with liver tumors (mostly cirrhotics with hepatocellular carcinoma). Our aim was to evaluate the short term efficacy of percutaneous interstitial laser photocoagulation in inducing focal ablation of liver tumors and the possible complications in patients with normal and impaired liver function. MATERIAL AND METHODS: Sixty-six patients (52-80 years; 42 men), 47 with 51 hepatocellular carcinoma nodules (diameter = 1.6-6.6 cm; mean 3.1 cm) on cirrhosis (18 in Child-Pugh A class, 24 in B e 5 in C class) and 19 patients with single liver metastasis (17 from colon, 2 from lung carcinoma; diameter = 3.9 cm; mean: 4.5 cm) underwent interstitial laser photocoagulation under ultrasound guidance. Depending on tumor size up to four needles were inserted in the tumor and multiple laser illuminations were performed: in nodules < or = 2 cm a single optical fiber and a single needle insertion were used, in nodules > 2 < 3 cm, 2-3 fibers were used with a single laser illumination, in nodules > 3 < 4 cm, 4 fibers were inserted and two laser illuminations were performed in the same session after 1.5 cm withdrawal of all fibers in the tumor, in nodules > 4 cm 2 sessions with 2 laser illuminations per session were performed. Necrosis of the nodules was evaluated with triphasic Helical CT 7 days after treatment. Patients with incomplete necrosis at CT were treated with additional interstitial laser photocoagulation sessions to attain complete necrosis. RESULTS: Fifty-eight patients underwent a single interstitial laser photocoagulation session, 7 patients 2 session and 1 patient 3 sessions. The range of administered energy per patient was 1200-32,000 Joules (mean: 6700 J). CT showed complete necrosis of 47 nodules in 43 patients with hepatocellular carcinoma and in 15/18 patients with metastasis. Three Child C class patients with mild ascites and hyperbilirubinemia before procedure (nodules O: 1.9, 3.5 and 5.8 cm) dropped out of CT follow-up because of severe liver function impairment with increased ascites and hyperbilirubinemia, associated with transient ileum paraliticus in 1 case. One of these patients died two months after treatment. Two patients with metastasis dropped out of treatment because of complications occurred after the interstitial laser photocoagulation session (1 ileum paraliticus, 1 gastric hemorrhage) and another one refused to continue the treatment.

Comparison of liver function tests after hepatic lobectomy and hepatic wedge resection.

Prior studies have suggested that changes in liver function tests may vary with the postoperative time interval and may be related to the extent of hepatic resection. This study describes characteristic profiles in parenchymal liver enzymes and other serum liver function tests over a 4-week course comparing anatomic to nonanatomic hepatic resections. The records of 48 patients undergoing successful major hepatic resection during a 3-year period were retrospectively reviewed. Of these 48 patients, 28 underwent formal anatomic resection (hepatic lobectomy), and 20 underwent nonanatomic resections (wedge resection). Routine postoperative management in lobectomy patients included drawing liver function tests and enzymes daily for the first week, then at approximately 2 and 4 weeks postoperatively. These tests included: prothrombin time (PT), partial thromboplastin time, total serum bilirubin, total protein (TP), aspartate transaminase, lactate dehydrogenase (LDH), alkaline phosphatase, albumin (A), and glucose. Patients undergoing wedge resections had these values checked less frequently, approximately 3 to 5 days, 2 weeks, and 4 weeks postoperatively. Profiles of these values were plotted over the 4-week postoperative time course for each group of patients. Patients undergoing hepatic lobectomy showed a characteristic laboratory value profile. PT elevated within 48 hours to a mean high of 16.0 seconds, then returned to normal by postoperative day 4. Partial thromboplastin time levels remained normal throughout the entire perioperative course. Total bilirubin rose slightly, to a mean high of 2.6 mg/100 cc, then returned to normal by postoperative day (POD) 14. Parenchymal liver enzymes aspartate transaminase and LDH rose abruptly to very high levels, then returned abruptly to normal (by POD 5). TP and A both fell to approximately 50 per cent of normal, gradually rising to normal by POD 14. Glucose rose to a mean high of 199 mg/100 cc within the first 5 days, then returned to normal by POD 7. Alkaline phosphatase remained normal initially, then showed a progressive rise to a high of 288 mg/100 cc on POD 14. Patients undergoing wedge resections did not show the same changes in total serum bilirubin, but showed similar trends in all other tests, although the magnitude of these changes was smaller. TP and A levels fell acutely after resection, then began a slow rise toward normal by POD 21. TP and A profiles were similar for both lobectomy patients and those undergoing wedge resection. The only tests that may have altered clinical management were the PT and total bilirubin. Patients undergoing major hepatic resection have characteristic postoperative profiles of liver enzymes and liver function tests. These laboratory profiles differ with the extent of hepatic resection. The profiles reflect changes in volume status, parenchymal liver destruction, transient hepatic insufficiency, and postoperative hepatic regeneration. However, except possibly for PT and bilirubin, the routine use of these tests is not recommended, given that the results do not alter clinical management.

Measurement of the whole body clearance of infused glycerol as a test of liver function after major hepatectomy.

Major liver resection can be used in the treatment of liver cancer. The functional capacity of liver parenchyma needs to be evaluated preoperatively because it conditions the outcome. We assessed whether the whole body clearance of glycerol, a substrate essentially metabolized in liver cells, may be suitable as a simple test of liver function. Seven patients after major hepatectomy, six patients after colectomy and 12 healthy subjects were studied. Patients were investigated on the first day after surgery. All participants were studied during a 150-min basal period followed by a 120-min infusion of 16 mumol kg-1 min-1 13C-labelled glycerol. Whole body glycerol clearance was calculated from the change in plasma glycerol concentration. Whole body glucose production was measured with 6,6 2H2 glucose infused as a tracer in the basal state and during glycerol infusion. In addition, 13C glucose synthesis was monitored to quantitate gluconeogenesis from glycerol. Patients after liver resection had higher plasma glycerol concentrations and lower whole body glycerol clearance than healthy subjects and patients after colectomy. They also had higher plasma glucagon concentrations. Their fasting glucose production was mildly elevated in the fasting state and did not change after glycerol infusion, indicating a normal hepatic autoregulation of glucose production. These results indicate that whole body glycerol clearance can be simply determined from plasma glycerol concentrations during exogenous glycerol infusion. It is significantly reduced in patients after major hepatectomy, suggesting that it constitutes a sensitive test of hepatic function. Its use as a preoperative testing procedure remains to be evaluated.

Abnormalities in liver function and coagulation profile following the Fontan procedure.

OBJECTIVE: To investigate liver function and coagulation disorders in patients with a Fontan circulation at different time intervals after surgery. DESIGN: Retrospective analysis of clinical data and cross sectional study relating liver function and coagulation profile to time since surgery, in 28 surviving patients after the modified Fontan procedure. PATIENTS: 20 patients (71%) with atriopulmonary anastomosis, seven (25%) with atrioventricular anastomosis, and one (4%) with total cavopulmonary connection. Follow up ranged from 2.0 to 21.8 years (mean 11.1). RESULTS: Abnormal liver function tests, mainly reflecting cholestasis, were present in 21 patients who had a significantly longer follow up (p < 0.01). Protein synthesis was normal in almost all patients. Coagulation profile showed abnormalities in 22 patients. "Procoagulant" abnormalities-that is, decreased plasminogen and protein C activity-were found in 11 and five patients, respectively. The extent of these abnormalities was less in patients with a longer follow up. Anticoagulant abnormalities were factor V deficiency in 16 patients and factor VII deficiency in 17, resulting in a prolonged prothrombin time in 19 patients. Thirteen patients had both pro- and anticoagulant abnormalities. A prethrombotic state was present in five patients, with a significantly longer mean time interval since surgery (p = 0.05). Thus, although the individual procoagulant indices decreased with increasing time intervals since surgery, a prethrombotic state was found particularly in patients with a long term follow up. CONCLUSIONS: Mild cholestasis was mainly present in Fontan patients with a long duration of follow up. Along with laboratory procoagulant abnormalities indicating a prethrombotic state, anticoagulant abnormalities were also present. The coagulation profile varied at different time intervals after surgery. Thus detailed evaluation should be performed regularly, and the use of anticoagulants should be considered in every patient. Long term prospective studies are needed to evaluate the individual fluctuations of coagulation profile over time following a Fontan procedure.

Intravenous tryptophan tolerance test for liver function.

An intravenous tryptophan tolerance test (ITrpTT) was designed for liver function since 95% Trp is metabolized by the liver. After an intravenous loading dose of 4 mg/kg body weight, serum levels of both free (F) and total (T) Trp were determined at 45 and 60 minutes. In normal controls and nonhepatic-disease patients, F45 (60) and T45 (60) did not exceed 7 mumol/L and 80 mumol/L, respectively, and F/T ratio not greater than 0.14. These were set up as cutoffs of upper normal limits. The test was abnormal in 87.5% of chronic persistent hepatitis (CPH) characterized by elevation of T45 (60), 100% of chronic active hepatitis (CAH) by elevation of F45 (60) and/or T45 (60), and 100% of hepatic cirrhosis by increase in F45 (60) and F/T ratio but not in T45 (60). The test seems to be more sensitive than the conventional tests for liver function. However, one should be cautious in interpretation of the test as there are some factors which might influence the Trp metabolism like exercise, alcoholism, corticosteroids and enzyme-inducers. It merits as an indication of liver dysfunction only when these factors are considered and excluded.

[Elective-selective Warren splenorenal shunt operation. Prognosis of liver function and esophageal varices hemorrhage after repeat sclerotherapy in liver cirrhosis].

From March 1st, 1982 to March 1st 1990 399 patients were admitted to the Heinz-Kalk-Hospital with recurrent bleeding from esophageal varices. Therapy of first choice was acute or elective endoscopic sclerotherapy. Early recurrences and uncontrollable hemorrhage were treated by Linton-Nachlas tube or if unsuccessful by devascularisation procedure. Two early or late bleeding recurrences were defined as sclerotherapy failures and choosen after passing a selection analysis (liver volume 1000 to 2500 ml, portal perfusion more than 30%, liver biopsy without activity or progression, exclusion of stenosis in the arterial supply of the liver and Child-Pugh classification A and B) for a selective-elective splenorenal Warren shunt (SRS). In 10 of 44 selected patients (11%) with an underlying disease of intrahepatic block in 95%, mostly alcoholic origin (65%) intraoperatively the performance of an SRS was technically problematic or impossible. Therefore, a mesocaval interposition shunt was carried out. Early mortality of 34 SRS was 5.9% (2 patients) and late mortality 17.6% (6 patients). No encephalopathy and shunt thrombosis were recorded. Postoperative angio- and sequential scintigraphies proved that portal perfusion was preserved during the first two years, but diminished. Liver function remained stable, too. One case of early rebleeding could be successfully managed by emergency endoscopic sclerotherapy. Five- and eight-years survival rate, according to the method of Kaplan-Meier is about 70%. We conclude that the SRS is the treatment of choice for elective management of recurrent bleeding of esophageal varices refractory to sclerotherapy. Its performance should be not enforced; in case of technical difficulties narrow-lumen mesocaval interposition shunt is an excellent alternative.

Prediction of postoperative decompensated liver function by technetium-99m galactosyl-human serum albumin liver scintigraphy in patients with hepatocellular carcinoma complicating chronic liver disease.

BACKGROUND: Preoperative technetium-99m galactosyl-human serum albumin (Tc-GSA) liver scintigraphy may predict postoperative decompensated liver function and its value has been investigated in patients having resection of hepatocellular carcinoma (HCC). METHODS: Hepatic uptake ratio of Tc-GSA (LHL15) was measured before operation in 30 patients. Postoperative complications were analysed retrospectively and compared with LHL15 values and other indicators evaluating hepatic function. RESULTS: The LHL15 of 22 patients without complications was 0.91 or more, compared with 0.90 or less in the eight patients who had complications. Multifactorial analyses showed that LHL15 and Child-Pugh grade significantly predicted postoperative complications (P < 0.0001 and P = 0.0111 respectively). LHL15 was a significant predictor of complications in patients with Child-Pugh grade B disease (n = 15, P = 0.0011). CONCLUSION: LHL15 was a reliable preoperative indicator of the risk of major postoperative complications in patients who had resection for HCC.

[Quantitative evaluation of liver function with 99mTc-GSA scintigraphy using extraction index].

Extraction index (EI5) was introduced to evaluate liver function quantitatively with 99mTc-GSA (GSA) scintigraphy, and it was compared with conventional indices; receptor index (LHL15) and clearance index (HH15). EI5 is expressed as following equation: EI5 = (L5 - L3)/(H3 + H5) * PH/PL where L3, L5: counts at 3 or 5 minutes after the injection in the liver ROI, respectively, H3, H5: counts at 3 or 5 minutes in the heart ROI, respectively; PL, PH: numbers of pixels in the liver- and heart-ROI, respectively. We performed GSA scintigraphy in 40 patients with liver dysfunction and calculated values of the indices. Good correlations were observed between EI5 and liver function tests. Correlation coefficients were almost equal to or higher than those between conventional parameters and liver functional tests. EI5 was thought to be a practical index, and it could be calculated in a short time without aid of computer. Evaluation of local liver function may be possible, because EI5 was corrected with numbers of pixels in the liver- and heart-ROI; which was not considered in the conventional parameters.

Findings on liver biopsy to investigate abnormal liver function tests in the absence of diagnostic serology.

BACKGROUND/AIMS: The significance of abnormal liver function tests in the absence of diagnostic serology is unclear. The aim of this study was to report liver biopsy findings in a large group of patients with unexplained abnormal liver biochemistry. METHODS: Histological findings were examined in 354 patients who underwent liver biopsy to investigate abnormal liver function tests. RESULTS: Six percent of patients had a normal liver biopsy while 26% were found to have some degree of fibrosis and 6% were cirrhotic. Thirty four and 32% of biopsies suggested non-alcoholic steatohepatits or fatty liver respectively. Other diagnoses included cryptogenic hepatitis, drug toxicity, primary and secondary biliary cirrhosis, autoimmune hepatits, alcohol-related liver disease, primary sclerosing cholangitis, haemochromatosis, amyloid and glycogen storage disease. Patient management was directly altered in 18% of patients due to liver biopsy findings and three families were entered into screening programmes for inheritable liver disease. CONCLUSIONS: The finding of abnormal liver function tests in the absence of diagnostic serology may indicate significant liver disease. Liver biopsy yields a range of liver diseases of diverse nature and extent. Liver diseases may be uncovered for which specific treatment is indicated.

Lidocaine metabolite formation as a measure of perioperative liver function.

In order to determine whether lidocaine metabolism, as the formation of monoethylglycinexylidide (MEGX), could be used as a quantitative index of perioperative liver function, serum levels of MEGX in 31 surgical patients were measured and compared with the results of conventional liver function tests. A significant correlation was found between the values of MEGX and ICGR15 in 20 of the 31 patients. The values of ICGR15 were lower than 20% in patients whose MEGX values were above 60 ng/ml and 20% or higher in those with MEGX values of lower than 60 ng/ml. There was also a significant correlation between MEGX values and antithrombin III values, and between MEGX values and the postoperative maximum levels of aspartate aminotransferase. However, no correlation was found between MEGX values and other preoperative conventional liver function tests in any of the 31 patients. We suggest that a cut-off MEGX value of 60 ng/ml be used as an indicator for satisfactory preoperative liver function. MEGX formation could be a useful prognostic index for patients who have undergone surgical procedures for liver disease, and employed as a quantitative assessment of perioperative liver function.

Pharmacologically stimulated portal flow measurement by magnetic resonance imaging for assessment of liver function.

PURPOSE: To evaluate pharmacologically stimulated portal flow measured by magnetic resonance (MR) imaging for assessment of liver function. MATERIALS AND METHODS: Pharmacologically stimulated portal flow was measured by phase contrast MR imaging in 27 patients when they were undergoing abdominal angiography for liver tumors or gall bladder cancer. The patients included 11 cases of liver cirrhosis and eight of chronic hepatitis. Pharmacological stimulation was done by infusion of 10 microg/Kg of nicardipine hydrochloride into the superior mesenteric artery through an angiographic catheter. We examined the correlation between stimulated or non-stimulated portal flow and biochemical liver function tests. RESULTS: Correlation coefficients and their corresponding p values between non-stimulated portal flow and the indocyanine green residual rate at 15 min after injection (ICG R15), serum albumin (ALB), total bilirubin (TB), cholinesterase (CHE), and hepaplastin test (HP) were--0.414 (0.056), 0.296 (0.134), -0.570 (0.002), 0.289 (0.153), and 0.321 (0.126), respectively, whereas those between stimulated portal flow and ICG R15, ALB, TB, CHE, and HP were--0.561 (0.007), 0.411 (0.033), -0.509 (0.007), 0.445 (0.023), and 0.494 (0.014), respectively. CONCLUSION: Stimulated portal flow showed better correlations with biochemical liver function tests than non-stimulated portal flow. It is suggested that stimulated portal flow measurement is more useful for the evaluation of liver function than non-stimulated portal flow measurement.

Role of the standard 'liver function tests' in current clinical practice.

A prerequisite of current therapy in liver disease is precise diagnosis. The rapid increase in the number of tests available--immunological, virological, histological and radiological--testifies to this, and reflects the inadequacy of the 'standard' liver function tests (LFTs). The LFTs are, however, in contrast to these more sophisticated tests, observer independent and despite their lack of specificity, several characteristic patterns of abnormality can be recognised which direct the physician to the most appropriate definitive investigation. The cheapness and non-invasive nature of the LFTs makes them particularly appropriate for monitoring the course of liver diseases once the diagnosis has been established and this, together with screening for hepatotoxicity of newly developed drugs, is now their main role. A second generation of liver function tests based on the capacity of the liver to eliminate various test compounds may come closer to offering a true estimate of liver function. More accurate methods of measuring the various bilirubin fractions, particularly bilirubin conjugates may also become available in the near future and provide more sensitive tests of liver dysfunction.

[Effects of an oxacephem antibiotic on liver function in orthopedic surgery].

The subjects were 531 patients who underwent orthopedic surgery. Flomoxef was administered, and liver function was examined before and after administration. Abnormal liver function after administration of flomoxef was found in 14.3% of patients. In male patients, a high rate of 18.8% was observed. A particularly high rate of 37.0% was obtained among patients who showed GOT values of more than 40 U/L before treatment with flomoxef. The prevalence of abnormal GOT and GPT values after administration of flomoxef was 3.6% and 13.2%, respectively. These values were significantly higher than those obtained with other cephem antibiotics. These rates of occurrence of abnormally high GOT and GPT are obviously higher than those submitted at the time of approval and reported in the drug use investigation. The prevalence of abnormal liver function values was high in patients receiving flomoxef, and particularly high in male patients and patients whose GOT was high before administration of flomoxef. Therefore, sufficient check of liver function appears important when administration of flomoxef to these types of patients is intended.

A possible beneficial effect of metronidazole in reducing TPN-associated liver function derangements.

Cholestasis and fatty infiltration of the liver are common complications of total parenteral nutrition (TPN). Following a recent suggestion that TPN-associated liver function derangements may be related to intestinal overgrowth of anaerobic bacteria, the effect of metronidazole on hepatic dysfunction during TPN in rats was investigated. After 5 days of TPN with either amino acids and glucose or amino acids with glucose and fat, all groups exhibited a mild weight gain, positive nitrogen balance, increased liver weight, increased liver:body weight ratio, increased levels of liver enzymes, and increased hepatic lipid content. The administration of metronidazole at 15 mg/kg/day significantly decreased the hepatic lipid content from 0.077 g fat/g liver for controls to 0.053 g fat/g liver. The efficacy of metronidazole in reducing hepatic fat accumulation during nutritionally effective and adequate TPN in rats suggests the possible involvement of anaerobic bacterial flora of the intestinal tract, at least in part, in the pathogenesis of TPN-associated liver function derangements. However, the various biochemical and morphological expressions of these changes and the discrepancy between unchanged liver weight, liver:body weight ratio, liver enzymes, and the improved hepatic fat content suggest multifactorial mechanisms for TPN-related liver damage.
