[Good results with liver resection for colorectal liver metastases].

OBJECTIVE: Evaluation of the results of partial liver resections in patients with colorectal carcinoma with liver metastases. DESIGN: Retrospective descriptive study. SETTING: Groningen University Hospital, the Netherlands. METHODS: Between January 1987 and December 1994, 62 patients were referred for liver resection for metastases of colorectal carcinoma (Dukes C 57%, Dukes B 40%, Dukes A 3%). Twenty-five of these patients were women and 37 men, ranging in age from 28 to 77 years (median 57 years). RESULTS: Liver resection was not performed in 29 patients because of unresectability of the liver lesions (n = 18), lymph node metastases found during laparotomy (4), multiple lung metastases (3) and other reasons (4). Thirty-three patients underwent potentially curative resection without mortality and with complications in 25%. Five-year survival and five-year disease-free survival were 51% and 22% respectively. Patients with a solitary metastasis showed a trend towards a longer survival than patients with two or more liver metastases because of a significantly higher rate of recurrent disease in the latter group of patients (p < 0.05). Nineteen patients (58%) developed recurrent disease between 3 to 44 months (median 15 months): relapse of the primary tumor (n = 7; 37%), recurrent liver metastases (6; 32%) lung metastases (5; 26%), and bone metastasis (I). CONCLUSIONS: Partial liver resections for metastatic disease of colorectal carcinoma can be performed without mortality and with acceptable morbidity. In case of solitary metastasis, liver resection is the therapy of choice as this is the only chance of long-term disease-free survival.

[Resections of recurrence in the liver of primary and secondary liver cancers].

1) Only one third of primary hepatic carcinomas and in particular hepatocellular carcinomas are amenable to liver resection. Approximately half of these patients develop tumor recurrences within the first two years accounting for the poor prognosis of this condition. The liver is the site of first failure in about 80 percent of patients. Secondary liver surgery for intrahepatic recurrence is technically possible in about one third of the patients at low operative mortality (< 5 percent). Long-term prognosis following potentially curative liver reresection for hepatosellular carwinoma compares favourably (5-year survival approximately 50 percent) with the prognosis after resection of the primary tumor. For potentially curative treatment liver transplantation is the only alternative to hepatic reresection, while alcohol injection and chemoembolization are merely palliative procedures. II) Liver resection represents the only potentially curative form of treatment for hepatic metastases from collorectal cancer. Operative mortality is generally less than 5 percent and 5-year survival of 20-40 percent can be expected. Secondary hepatic recurrences following hepatic resection of colorectal metastases are amenable to reresection in approximately 10 percent of patients. Selection criteria for reresection are the same as for primary liver reresection. Median survival following secondary liver resection is 32 months and this is identical to the median survival after the first liver resection for colorectal metastases.

Evidence that host size determines liver size: studies in dogs receiving orthotopic liver transplants.

Orthotopic liver transplantation was performed in two groups of dogs; Group I animals consisted of large dogs that served as recipients of livers obtained from smaller dogs while Group II animals consisted of dogs that received liver from donor dogs of nearly the same size. The small-for-size livers transplanted into the Group I dogs rapidly increased in size over the course of 2 weeks until they achieved a size equal to that originally present in the larger recipient dogs. In contrast, the livers transplanted into dogs of the same size as the donors underwent some degree of atrophy. In both groups of animals, plasma levels of insulin and glucagon and hepatic (graft) activities of thymidine kinase and ornithine decarboxylase were followed serially. The only difference between the two groups of animals for these measures was that the ornithine decarboxylase activity rose to a greater degree in the liver that underwent graft enlargement. These data suggest that recipient size determines, at least in part, liver graft size once it is transplanted. These data also suggest that of the parameters followed, only ornithine decarboxylase activity parallels the finding of growth of the transplanted liver.

Protective effect of vasodilators on liver function after long hypothermic preservation: a study in the isolated perfused rat liver.

The effects of two vasodilators, papaverine and pentoxifylline (a methylxanthine derivative), on liver function after 19 hr hypothermic preservation were investigated. Hypothermic preservation was performed according to the standard technique, and liver hemodynamics and function were studied during 70 min immediately after reperfusion in an isolated perfused rat liver system. No significant changes occurred after hypothermic storage for 5 hr. However, when the storage was prolonged to 19 hr, bile flow and taurocholate intrinsic clearance were significantly reduced; transaminase release was markedly increased and histological studies demonstrated centrilobular necrosis. Concomitantly, liver blood flow was significantly reduced and intrahepatic vascular resistance was increased. Papaverine and pentoxifylline administered during preservation and at the time of reperfusion significantly improved all parameters. The improvement was more pronounced after pentoxifylline, and this group showed no significant difference in any of the studied parameters from the control livers. The results show that two vasodilators significantly protect the liver during long hypothermic preservation. The data suggest that abnormalities of liver microcirculation are of major importance in the pathogenesis of liver injury after hypothermic storage.

Increased galactose clearance after liver transplantation: a measure of increased blood flow through the denervated liver?

This study measured the liver blood flow-dependent index of galactose clearance in patients after liver transplantation, to test the hypothesis that liver blood flow is increased in the denervated liver. Eight normal subjects and 16 patients 1 to 8 months after liver transplant were studied. All patients were stable with no evidence of severe rejection at the time of study. Galactose clearance was measured at steady state during continuous infusion of 75 mg per min of 5% galactose. The results show a statistically significant (p less than 0.01) higher average galactose clearance in the transplant patients (1,187 +/- 316 ml per min per m2) compared to the control group (709 +/- 121 ml per min per m2). The major limiting factor in galactose clearance at low concentrations is liver blood flow, and we interpret these data as evidence for increased blood flow in the transplanted liver. Possible mechanisms for the increased galactose clearance are (i) loss of normal vasomotor tone in the denervated liver, or (ii) persistence of abnormal systemic hemodynamics after transplantation. Elucidation of these mechanisms awaits further study.

Transdiaphragmatic liver scanning: a new intraoperative imaging technique for examination of the liver from the thoracic cavity.

In order to examine the liver during thoracotomy, a new intraoperative imaging technique called "transdiaphragmatic liver scanning" was developed. Transdiaphragmatic scanning performed with high-frequency transducers provided clear visualization of the entire liver from the thoracic cavity through the diaphragm. In our study, transdiaphragmatic scanning was used in 27 thoracotomy operations performed for the treatment of malignant diseases, including lung and esophageal cancers. One 5-mm liver cyst, one 3-mm x 4-mm hemangioma, and one 5-mm x 6-mm ill-defined lesion (possible metastasis), all of which were unrecognized preoperatively, were detected. In 3 operations, preoperatively suspected liver metastases were excluded by transdiaphragmatic scanning. Because transdiaphragmatic scanning provides high-resolution images of the liver and is the only method capable of examining the liver during thoracotomy, this intraoperative scanning technique may become a useful tool in the evaluation of liver metastases from thoracic or mediastinal malignancies.

Porcine partial liver transplantation: a novel model of the "small-for-size" liver graft.

Increasing shortage of cadaveric grafts demands the utilization of living donor and split liver grafts. The purpose of this study was to 1) define the "small-for-size" graft in a pig liver transplant model 2) evaluate pathological changes associated with small-for-size liver transplantation. Pigs were divided into four groups based on the volume of transplanted liver: (a) control group (n=4), 100% liver volume (LV) (b) group I (n=8), 60% LV (c) group II (n=8), 30% LV (d) group III (n=15), 20% LV. Tacrolimus and methyl prednisone were administered as immunosuppression. Animals were followed for 5 days with daily serum biochemistry, liver biopsies on day 3 and 5 for light microscopy, and tissue levels of thymidine kinase (TK) and ornithine decarboxylase (ODC). Liver grafts were weighed pretransplant and at sacrifice. All the recipients of 100%, 60%, and 30% grafts survived. Transplantation of 20% grafts (group III) resulted in a 47% mortality rate. Group III animals showed significantly prolonged prothrombin times (p<0.05), elevated bilirubin levels (p<0.05), and ascites. The rate of regeneration, as indicated by TK activity and graft weight was inversely proportional to the size of the transplanted graft. The severity of the microvascular injury was inversely proportional to graft size and appeared to be the survival-limiting injury. Frank rupture of the sinusoidal lining, parenchymal hemorrhage, and portal vein injury were prominent in group III animals 1 hour following reperfusion. This study established a reproducible large animal model of partial liver grafting; it defined the small-for-size syndrome in this model and described the associated microvascular injury.

Malignant vascular tumors of the liver presenting as liver failure and portal hypertension.

We describe three patients referred for orthotopic liver transplantation with liver failure and portal hypertension who were found to have malignant vascular tumors: two patients with angiosarcoma and one patient with epithelioid hemangioendothelioma. Their clinical presentation mimicked decompensated chronic liver disease. None had tumor masses on computed tomography and ultrasonography. Massive tumor involvement of the liver was identified in the two patients studied by magnetic resonance imaging. Pathological examination of the explanted liver at the time of transplantation in one patient and autopsy in a second patient showed angiosarcoma. Laparoscopic liver biopsies in the third patient showed epithelioid hemangioendothelioma. The vascular origin of the tumor was established by histopathologic examination and confirmed with immunohistochemistry. Malignant vascular tumors of the liver should be included in the differential diagnosis of liver failure of unclear etiology.

Prostaglandins in liver failure and transplantation: regeneration, immunomodulation, and cytoprotection. Prostaglandins in Liver Transplantation Research Group.

Prostaglandins (PG) are involved in the regulation of many physiological processes in the liver and play a major role in the pathophysiology and treatment of liver diseases. In addition to their effects of cell growth and immune function, PGs have shown cytoprotective effects on hepatocytes in various toxic, ischemic, and infectious models of liver injury. Although the mechanisms for these beneficial effects have not been precisely delineated, synthetic PG analogues have increasingly been used in patients with acute liver failure and chronic liver disease. There is also increasing evidence suggesting that PGs may reduce the early morbidity and mortality associated with liver transplantation, particularly in the context of primary graft nonfunction and renal dysfunction associated with cyclosporine and tacrolimus therapy. PG analogues have also been used for the treatment and control of recurrent hepatitis B virus infection in liver allograft recipients. The purpose of this review is to evaluate the role of PGs in hepatic physiology and disease and to review the use of synthetic PG analogues in the clinical settings of liver failure and transplantation.

The impact of liver preservation in HTK and UW solution on microcirculation after liver transplantation.

Severe microcirculatory disturbances due to endothelial cell damage and leukocyte adherence during reperfusion of transplanted livers are considered to contribute to early graft failure. Since the degree of reperfusion injury after liver transplantation depends on the length of preservation time and the solution used for preservation, the aim of our study was to assess three solutions with respect to microvascular perfusion and leukocyte adhesion. Therefore, rat livers were stored up to 24 h in Euro-Collins (EC), University of Wisconsin (UW), or histidin-tryphtophan-ketoglutarate (HTK) solutions prior to orthotopic transplantation. The livers were studied in situ 60 min postoperatively using intravital fluorescence video microscopy. Using simple syringe flushing (10 ml), sinusoidal perfusion decreased below 50% in EC preserved livers after 8 h preservation, in HTK preserved livers after 16 h preservation, and remained higher than 70% in livers preserved in UW up to 24 h. Permanent adhesion of leukocytes was increased more rapidly in organs after 1, 8, 16, and 24 h preservation in HTK (16%, 15%, 34%, and 49.7% +/- 4.7%) compared to those preserved in UW (15%, 18%, 17%; and 32.7% +/- 3.3%; P<0.05). Using a 10-fold volumn of the organ weight of HTK solution during the harvesting procedure, with an 8 min equilibration period, sinusoidal perfusion (39.6 +/- 4.7%) and leukocyte adhesion (42.7 +/- 3.1%) were not improved after 24 h. In contrast, equilibration with a volumn of approximately 40-times the liver weight improved sinusoidal perfusion (70.8% +/- 2.7%; P < 0.01) and leukocyte adhesion (24.9% +/- 3.1%; P < 0.01) significantly. Thus, using HTK solution, simple flushing prior to long-term cold storage resulted in microcirculatory disturbances when compared to UW solution. Larger volumns of HTK solution with an additional equilibration period of 8 min, however, reduced leukocyte adhesion and improved sinusoidal perfusion to a similar degree as UW solution.

Auxiliary heterotopic partial liver transplantation in pigs with acute liver failure.

Fulminant hepatic failure is usually fatal without liver transplantation; however, orthotopic liver transportation is often difficult to perform due to the high risk of coagulopathy and the development of multiple organ failure. Auxiliary heterotopic partial liver transplantation (APLT), However, has the potential to provide an effective hepatic support system considering that the host liver is left in situ and the surgical procedure is less invasive. In this report, we describe the beneficial effects of performing 60% APLT on the hepatic function and survival of pigs with acute hepatic failure induced by hepatic artery ligation. The pigs were divided into a control group of nine animals (group 1) that had portal vein and hepatic artery ligation with a side-to-side portacaval shunt, and an APLT group of seven animals (group 2) that had portal vein and hepatic artery ligation with APLT. The two left lateral lobes of the donor liver were resected, reducing the liver weight to about 60%, and the graft was placed in the right subhepatic space. No deaths occurred intraoperatively. In group 1, eight pigs died of massive liver necrosis within 48 h and one died between 48 and 72 h (median survival 23 h). In group 2, two pigs died within 72 h due to preservation or anesthetic problems, but five survived for more than 3 days (median survival 13.4 days), with a significant difference between the two groups (P < 0.05). One animal was killed 30 days after APLT and excellent graft function was demonstrated by the synthesis of clotting factors, ammonia detoxification, and glucohomeostasis. Moreover, evidence of hepatic regeneration was found in the transplanted livers.(ABSTRACT TRUNCATED AT 250 WORDS)

Circulating IgA immune complexes and skin IgA deposits in liver disease. Relation to liver histopathology.

Alcoholic liver disease (ALD) is characterized by elevated serum IgA concentrations, the presence of circulating immune complexes containing IgA, and IgA deposits along sinusoids in the liver. When combined with the presupposed IgA-clearance function of the liver, a causal association between IgA abnormalities and the liver disease in ALD can be suggested. This prompted us to study the presence and concentration of circulating IgA-containing immune complexes (IgA-CIC) in 41 patients with ALD and 41 patients with other nonalcoholic liver diseases having comparable serum IgA levels. We searched for relationships among IgA-CIC and history of alcohol abuse, liver histopathology, and IgA deposits in the liver. Using an anti-IgA inhibition binding assay, 56% of the patients exhibited IgA-CIC in polyethylene glycol precipitate of serum and 38% showed IgA-CIC in whole serum. The prevalence and concentration of IgA-CIC was lowest in cases with nonspecific changes or steatosis in the liver biopsy and highest in cases with hepatitis or cirrhosis (P less than 0.01). The occurrence of IgA-CIC was not related to a history of alcohol abuse or to the presence of IgA deposits along hepatic sinusoids (which occurred in 78% of ALD and 20% of non-ALD cases). A skin biopsy was available from 34 patients (19 with ALD and 15 with non-ALD). In 68% of these biopsies, IgA deposits were observed in superficial blood capillaries.(ABSTRACT TRUNCATED AT 250 WORDS)

High prevalence of osteoporosis in patients with chronic liver disease prior to liver transplantation.

Osteoporosis is a common complication of liver transplantation. Its pathogenesis is multifactorial, but preexisting bone disease in patients with chronic liver disease is likely to play an important role. The aim of this study was to evaluate bone mineral density in adult patients with chronic liver disease prior to liver transplantation. A total of 243 consecutive patients (128 male, 115 female; mean age 51.1years) with chronic liver disease undergoing assessment for transplantation, were recruited over a 4-year period. BMD measurements were made using dual energy X-ray absorptiometry in the lumbar spine (L1-L4) and femoral neck (FN). Osteoporosis and osteopenia were defined by WHO criteria. Osteoporosis at either L1-L4 or FN was present in 36.6%, osteopenia in 48.1%, and normal BMD in only 15.2% of patients. There was no difference in prevalence of osteoporosis between males and females (P = 0.442). Women with osteoporosis were on average 10 years older (56.2 +/- 1.4 years) than those with normal bone density (46.4 +/- 2.3 years) P = 0.002; in men, no statistically significant age effect was found. Patients with osteoporosis had on average lower body weight than those with normal bone density (64.9 +/- 1.8 kg vs 74.2 +/- 2.2 kg) P = 0.003. T-scores in patients with cholestatic liver disease were lower than in non-cholestatic disease and the lowest BMD values were found in patients with cystic fibrosis. Logistic regression revealed that in women, increasing age (P = 0.004; OR = 1.12; CI 1.04-1.21) and lower body weight (P = 0.01; OR = 0.95; CI 0.91-0.99) were significant independent risk factors for osteoporosis but menopausal status (P = 0.1; OR = 0.24; CI 0.05-1.32) and presence or absence of cholestasis (P = 0.326; OR = 1.54; CI 0.65-3.67) were not. There were no independent risk factors in men. This study demonstrates a high prevalence of osteoporosis in patients with chronic liver disease prior to liver transplantation, men and women being equally affected. With the exception of increasing age and lower body weight in women, no independent risk factors were found, emphasizing the importance of BMD measurements in these patients and the need for prophylactic measures to optimize bone health.

Localization of liver myofibroblasts and hepatic stellate cells in normal and diseased rat livers: distinct roles of (myo-)fibroblast subpopulations in hepatic tissue repair.

Previous in vitro studies indicated that hepatic stellate cells (HSC) and rat liver myofibroblasts (rMF) have to be regarded as different cell populations of the myofibroblastic lineage with fibrogenic potential. Employing the discrimination features defined by these studies the localization of HSC and rMF was analyzed in diseased livers. Normal and acutely as well as chronically carbon tetrachloride-injured livers were analyzed by immunohistochemistry and by in situ hybridization. In normal livers HSC [desmin/glial fibrillary acid protein (GFAP)-positive cells] were distributed in the hepatic parenchyma, while rMF (desmin/smooth muscle alpha actin-positive, GFAP-negative cells colocalized with fibulin-2) were located in the portal field, the walls of central veins, and only occasionally in the parenchyma. Acute liver injury was characterized almost exclusively by an increase in the number of HSC, while the amount of rMF was nearly unchanged. In early stages of fibrosis, HSC and rMF were detected within the developing scars. In advanced stages of fibrosis, HSC were mainly present at the scar-parenchymal interface, while rMF accounted for the majority of the cells located within the scar. At every stage of fibrogenesis, rMF, in contrast to HSC, were only occasionally detected in the hepatic parenchyma. HSC and rMF are present in normal and diseased livers in distinct compartments and respond differentially to tissue injury. Acute liver injury is followed by an almost exclusive increase in the number of HSC, while in chronically injured livers not only HSC but also rMF are involved in scar formation.

Aspects of our liver support systems using extracorporeal xenoperfusion of pig or baboon liver: review.

Artificial liver support systems using xenoperfusion of pig or baboon liver have metabolic activity and there is the possibility that they could substitute for total liver functions; however, several problems have yet to be solved. In our early clinical experience, a method of cross-hemodialysis with interposed cuprophane membrane was employed in order to avoid immunological reactions in patients. Sixteen patients with hepatic failure were treated by this method. Although the coma grade was ameliorated in 65% of the patients, the ultimate survival rate was 18.9%. In this clinical trial, the indication for liver support was clarified based on hepatic mitochondrial functions. This unsatisfactory result could also be attributed to insufficient effects of the device, due to the interposed membrane, and also to damage of the supporting livers due to hyperacute xenoperfusion injury. Recent investigations in the field of xenotransplantations have shown us possibilities for controlling xenogeneic hyperacute rejection. Suppression of complement activation enabled long-term xenoperfusion of supporting livers with high metabolic activity. The administration of prostaglandin E1 or soluble complement receptor type 1, and the use of transgenic pig livers expressing human decay-accelerating factor, may be promising methods to establish highly active artificial liver support systems using xenoperfusion.

Comparison of anamnestic history, alcohol intake and smoking, nutritional status, and liver dysfunction between thorotrast patients who developed primary liver cancer and those who did not.

In order to clarify the differences in past history, nutritional condition and, consumption of alcohol and tobacco, and liver dysfunction between the thorotrast patients who developed primary liver cancer and those who did not, 103 persons who had no primary liver cancer in January 1980 were studied. All subjects were military men who had undergone angiography with thorotrast between 1943 and 1946. Twenty persons developed hepatocellular carcinoma and 16 developed intrahepatic bile duct carcinoma by April 1987, whereas 67 are still alive without any cancer. There was no difference in age or period after thorotrast infusion between those two groups of patients in January 1980. A difference in history of hepatitis and/or jaundice and presence of hepatic dysfunction was found between the subjects who developed primary liver cancers and those who did not. These findings suggest that an anamnestic history of hepatitis and liver dysfunction are risks for development of thorotrast-induced liver cancer. On the basis of the above findings, early detection of liver dysfunction offers a possibility of early diagnosis of primary liver cancer.

Preoperative TNM-classification is a better prognostic indicator for recurrence of hepatocellular carcinoma after liver transplantation than albumin mRNA in peripheral blood. Liver Transplant Oncology Group.

BACKGROUND/AIM: Survival after orthotopic liver transplantation for hepatocellular carcinoma is limited by a high rate of tumor recurrence. A polymerase chain reaction assay based on the detection of albumin mRNA expression in peripheral blood for detection of hematogenous micrometastasis of hepatocellular carcinoma has been described, which may help to select candidates for orthotopic liver transplantation. METHODS: The prognostic value of a highly sensitive nested reverse transcription-polymerase chain reaction assay was evaluated in comparison with the TNM-classification of the International Union against Cancer in a population of liver transplant candidates. RESULTS: Eighty patients with liver disease and 42 control patients were evaluated. Six of 21 patients with hepatocellular carcinoma and 11 of 59 patients with other diseases of the liver were positive for albumin reverse transcription-polymerase chain reaction, making this assay an indicator of ongoing liver damage without absolute specificity for hepatocellular carcinoma. Twelve patients with hepatoma were followed after liver transplantation and seven of those patients had a tumor recurrence within 12 months. Six of these patients with recurrence had International Union against Cancer stage IV A tumors preoperatively, while only one of them was positive for albumin reverse transcription-polymerase chain reaction before transplantation. Only one patient with a stage I to III tumor had a recurrence within 12 months. CONCLUSIONS: Detection of albumin mRNA in peripheral blood by reverse transcription-polymerase chain reaction seems to be an unreliable marker for assessing hematogenous spread of hepatocellular carcinoma. With International Union against Cancer stage IV A being a much better predictor of tumor recurrence, the practical value of albumin mRNA reverse transcription-polymerase chain reaction for patient selection in liver transplant candidates seems to be very limited.

Influence of liver failure, ascites, and energy expenditure on the response to oral nutrition in alcoholic liver cirrhosis.

The influence of liver failure, ascites, and energy expenditure on the response to oral nutrition was assessed in a group of 55 alcoholic cirrhotic patients. Caloric intake, nutritional status, resting energy expenditure (REE), and Child-Pugh score were evaluated before and after 1 mo of oral nutrition. Patients were severely malnourished, 73% had muscular midarm circumference (MMAC) below the 5th percentile of a reference population, 51% had triceps skinfold thickness below the 25th percentile. Eleven patients were in class A of Child, 19 in class B, and 25 in class C. Twenty-six patients were nonascitic, whereas ascites was resolved in 10 ascitic patients by the end of the study and 19 patients had refractory ascites. Liver damage was more pronounced and did not improve during the study in patients with refractory ascites. Caloric intake was approximately 40 kcal/kg of body weight and was in the same range in the three groups according to Child classification. Fat mass (FM) increased, respectively, from 17.4% +/- 1.7% to 19.5% +/- 1.4%, P < 0.01, in Child A patients; from 17.1% +/- 1.4% to 19.3% +/- 1.4%, P < 0.001, in Child B patients; and from 17.6% +/- 1.5% to 18.8% +/- 1.5%, P < 0.05, in Child C patients. The increase in FM was comparable in the three groups, whereas MMAC and the creatinine/height ratio did not change significantly. FM was lower and did not increase in patients with refractory ascites. Child C patients were characterized by an increase in the rate of glucose oxidation (P < 0.02) and a decrease in the rate of lipid oxidation (P < 0.05). High-density lipoprotein cholesterol and apolipoprotein (Apo) A1 were reliable indices of improvement of liver function in patients with severe liver failure, ApoA1 was also a marker of improvement of metabolic impairment. With respect to the measured REE/predicted REE ratio calculated according to Harris-Benedict equation (r), 19 patients were considered hypermetabolic (r < 1.1), 30 normometabolic (0.9 < r < 1.1), and 6 hypometabolic (r < 0.9). An increase in FM correlated with r (P < 0.01) and was more marked in hypermetabolic patients. In contrast to the other two groups, Child-Pugh score and nutritional status remained unchanged in the hypometabolic patients. These results show that severe liver failure did not preclude improvement of nutritional status provided caloric intake was high. In Child C patients, improvement of nutritional status paralleled improvement of liver function and normalization of oxidative metabolism. Refractory ascites had negative effects on changes in nutritional status and liver function. Despite adequate caloric intake to energy requirements, hypometabolism has a poor prognosis regarding both nutritional status and liver function.
