Abstract
INTRODUCTION Effect of long-term growth-hormone (GH) therapy in decompensated cirrhosis (DC) is unknown. We studied the safety and efficacy of GH therapy on malnutrition, nitrogen metabolism, and hormonal changes in patients with DC. METHODS Patients with DC were randomized to standard medical therapy plus GH (group A; n = 38) or standard medical therapy alone (group B; n = 38). Body mass index, midarm muscle circumference (MAMC), hand grip strength (HGS), liver frailty index (LFI), skeletal muscle index (SMI), nitrogen balance, Child-Turcotte-Pugh, model for end-stage liver disease, quality of life (QOL), serum albumin, GH, insulin like growth factor-1, and acid labile subunit (ALS) were assessed at baseline and at 12 months. RESULTS The mean difference between baseline and 12-months in SMI (-6.122 [-9.460 to -2.785] cm 2 /m 2 ), body mass index (-2.078 [-3.584 to -0.5718] kg/m 2 ), MAMC (-1.960 [-2.928 to -0.9908] cm), HGS (-5.595 [-7.159 to -4.031] kg), albumin (-0.3967 [-0.6876 to -0.1057] g/dL), LFI (0.3328 [0.07786-0.5878]), Child-Turcotte-Pugh (0.9624 [0.1435-1.781]), model for end-stage liver disease (1.401 [0.04698-2.75]), insulin-like growth factor-1 (-6.295 [-11.09 to -1.495] ng/dL), and ALS (-8.728 [-14.12 to -3.341] pg/mL) were statistically significantly better ( P < 0.05) in group A. There was no improvement in nutritional parameters, clinical scores, QOL scores, or nitrogen balance in group B. The mean difference between group A and B in SMI, HGS, MAMC, LFI, ALS, physical component summary, and mental component summary at 12 months was also statistically significant. Survival at 12 months was similar in both groups ( P = 0.35). No serious adverse events were observed. DISCUSSION Long-term use of GH is safe in DC and leads to improvement in malnutrition and possibly QOL. However, there is no improvement in 12-month survival (NCT03420144).

Abstract
AIM Sarcopenia has a high prevalence and can be an adverse predictor in patients with chronic liver diseases (CLDs). We sought to assess the prevalence of sarcopenia and its prognostic significance in patients with CLDs at multiple centers in Japan. METHODS In this retrospective study, we collated the data of 1624 patients with CLDs (976 men). The diagnosis of sarcopenia was determined by the sarcopenia assessment criteria of the Japan Society of Hepatology. Predictors of mortality were identified using univariate and multivariate analyses. RESULTS Muscle weakness and skeletal muscle loss occurred in 33.5% and 29.3% of all subjects, respectively, while sarcopenia occurred in 13.9% of all patients. Patients with sarcopenia had a poorer prognosis among all patients, patients with hepatocellular carcinoma (HCC), and those without HCC by log-rank test. The multivariate Cox proportional hazards model identified female gender (hazard ratio [HR], 0.59; p = 0.03), alcoholic liver disease (HR, 4.25; p < 0.01), presence of HCC (HR, 6.77; p < 0.01), Child-Pugh classes A (HR, 1.42; p < 0.05), B (HR, 2.70; p < 0.01), and C (HR, 6.30; p < 0.01), and muscle weakness (HR, 2.24; p < 0.01) as significant adverse predictors. The cut-off values of handgrip strength (HGS) for prognosis determined by maximally selected rank statistics were calculated as 27.8 kg for men and 18.8 kg for women. CONCLUSION Reduced HGS in patients with CLD was an independent adverse predictor of mortality, with cut-off values of 27.8 kg for men and 18.8 kg for women.

Possible correlation between increased serum free carnitine levels and increased skeletal muscle mass following HCV eradication by direct acting antivirals. Sci Rep 2021; 11:16616. [PMID: 34400736 PMCID: PMC8368156 DOI: 10.1038/s41598-021-96203-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 08/06/2021] [Indexed: 12/30/2022] Open
Abstract
We aimed to evaluate factors associated with changes in skeletal muscle mass in hepatitis C virus (HCV)-infected patients after treatment with direct-acting antivirals (DAAs). Consecutive HCV-infected patients after treatment with DAA were recruited into the study. Patients who achieved sustained virological response (SVR); and had complete clinical information, preserved serum samples at baseline and SVR48, and skeletal muscle mass evaluations based on the psoas muscle mass index (PMI) on computed tomography at baseline and ≥ 12 months were included. Altogether, 70.7% of patients (41/58) showed increased PMI after DAA therapy, and mean relative PMI was significantly higher after DAA therapy than at baseline. There were no significant associations between baseline clinical factors routinely examined in clinical practice and increased PMI. Among factors reported to be associated with skeletal muscle loss in patients with chronic liver disease, serum zinc levels and total and free carnitine levels increased significantly after DAA therapy and only changes in serum free carnitine levels were significantly associated with an increased PMI (r = 0305, P = 0.020). In conclusion, increased skeletal muscle mass after successful HCV eradication by DAAs was significantly associated with increased serum-free carnitine levels. L-carnitine supplementation may be beneficial in patients with low skeletal muscle mass after DAA.

Abstract
Hepatitis C virus (HCV) infection can cause renal dysfunction, expected to improve upon HCV eradication. However, adverse effects of HCV eradication using direct-acting antiviral agents (DAAs) on renal function have been recently reported. This retrospective study aimed to evaluate renal function with glomerular filtration rate (eGFR) estimated using creatinine (eGFRcre) and cystatin C (eGFRcys). Complete clinical information and preserved serum samples were collected from 207 patients with HCV infection treated with interferon-free DAA at baseline and SVR48 (SVR48). Patients who underwent paired computed tomography (CT) at baseline and ≥12 months after DAA were evaluated for changes in skeletal muscle mass using the psoas muscle mass index (PMI). eGFRcre significantly worsened at SVR48, while eGFRcys was similar at baseline and SVR48. At baseline, eGFRcre was significantly higher than eGFRcys; eGFRcre and eGFRcys were similar at SVR48. Multivariate analysis revealed that the presence of liver cirrhosis and low-albumin level, as well as cirrhosis and age, was significantly associated with the overestimation of renal function by eGFRcre at baseline and SVR48, respectively. In the 57 patients who underwent paired CT at baseline and ≥12 months after DAA, relative values of PMI significantly increased after DAA. After DAA, in patients with increased PMI (65% 37/57), eGFRcre significantly worsened but did not change in patients without increased PMI. eGFRcre significantly worsened after DAAs; however, this might not reflect accurate changes in renal function, partially because of changes in skeletal muscle mass. eGFRcys did not change after DAAs, and it is a potential alternative to eGFRcre.

Abstract
Introduction: Sarcopenia is defined as loss of skeletal muscle mass, strength, and function, and it is associated with increased morbidity and mortality in patients with chronic liver disease.Areas covered: The aim of this review is to provide a detailed report on the pathophysiological mechanisms underlying sarcopenia in cirrhotic patients, the several imaging methods available for the assessment of sarcopenia and the clinical studies evaluating the prognostic role of sarcopenia presence in cirrhotic patients.Expert opinion: Sarcopenia pathogenesis is complex and multifaceted, as chronic catabolic conditions, increased energy expenditure, reduced appetite, side effects of multiple therapies, alterations in circulating levels of hormones, low protein synthesis, presence of ascites or portosystemic shunts are all factors contributing to muscle atrophy in cirrhotic patients. Computed tomography scan is the most validated method to evaluate muscle mass and quality. Sarcopenia is associated with a higher rate waitlist mortality, hepatic encephalopathy, and lower quality of life in patients with liver cirrhosis. Future studies should make an effort to unify and validate liver disease-specific cutoffs for the definition of sarcopenia.

Abstract
UNLABELLED This study aimed to determine the optimal psoas muscle mass index (PMI) cut-off values for diagnosis of skeletal muscle mass loss. METHODS We evaluated PMI in two groups of normal controls: a medical check-up group and a liver donation candidate group. We analyzed two novel PMI cut-off values, one based on the mean - two standard deviations (2SD) and one based on the lower 5%. Skeletal muscle mass index (SMI) evaluations using computed tomography (sliceOmatic; TomoVision) and bioelectrical impedance analysis and PMI evaluation were undertaken simultaneously. We analyzed the correlation between our PMI cut-off values and the Japan Society of Hepatology-defined SMI cut-off values. The prevalence of skeletal muscle mass loss in patients with liver disease was assessed using the novel PMI cut-off values. RESULTS In 504 normal controls aged ≤50 years, the PMI cut-off values based on mean -2SD and the lower 5% were set at 3.30 cm2 /m2 for men and 1.69 cm2 /m2 for women and 3.74 cm2 /m2 for men and 2.29 cm2 /m2 for women, respectively. The PMI cut-off values based on the lower 5% alone showed that skeletal muscle mass loss increased with age. Furthermore, they correlated well with Japan Society of Hepatology-defined SMI (sliceOmatic) cut-off values and showed a significantly higher prevalence of skeletal muscle mass loss in patients with liver cirrhosis than those without liver cirrhosis. CONCLUSIONS We propose the following PMI cut-off values: 3.74 cm2 /m2 for male individuals and 2.29 cm2 /m2 for female individuals. These cut-off values can facilitate accurate diagnosis and management of sarcopenia in patients with chronic liver disease.

Abstract
A frequent complication in liver cirrhosis is malnutrition, which is associated with the progression of liver failure, and with a higher rate of complications including infections, hepatic encephalopathy and ascites. In recent years, the rising prevalence of obesity has led to an increase in the number of cirrhosis cases related to non-alcoholic steatohepatitis. Malnutrition, obesity and sarcopenic obesity may worsen the prognosis of patients with liver cirrhosis and lower their survival. Nutritional monitoring and intervention is therefore crucial in chronic liver disease. These Clinical Practice Guidelines review the present knowledge in the field of nutrition in chronic liver disease and promote further research on this topic. Screening, assessment and principles of nutritional management are examined, with recommendations provided in specific settings such as hepatic encephalopathy, cirrhotic patients with bone disease, patients undergoing liver surgery or transplantation and critically ill cirrhotic patients.

Abstract
UNLABELLED Decompensated cirrhosis (DC) carries a high mortality. Liver transplantation (LT) is the treatment of choice; however, the limited availability of donor organs has resulted in high waitlist mortality. The present study investigated the impact of multiple courses of granulocyte-colony stimulating factor (G-CSF) with or without growth hormone (GH) in these patients. Sixty-five patients with DC were randomized to standard medical therapy (SMT) plus G-CSF 3 monthly plus GH daily (group A; n = 23) or SMT plus G-CSF (group B; n = 21) or SMT alone (group C; n = 21). The primary outcome was transplant-free survival (TFS) at 12 months. Secondary outcomes were mobilization of CD34+ cells at day 6 and improvement in clinical scores, liver stiffness, nutrition, episodes of infection, and quality of life (QOL) at 12 months. There was significantly better 12-month TFS in groups A and B than in group C (P = 0.001). At day 6 of therapy, CD34+ cells increased in groups A and B compared to baseline (P < 0.001). There was a significant decrease in clinical scores, improvement in nutrition, better control of ascites, reduction in liver stiffness, lesser infection episodes, and improvement in QOL scores in groups A and B at 12 months as compared to baseline (P < 0.05). The therapies were well tolerated. CONCLUSION Multiple courses of G-CSF improved 12-month TFS, mobilized hematopoietic stem cells, improved disease severity scores, nutrition, fibrosis, QOL scores, ascites control, reduced infections, and the need for LT in patients with DC. However, the use of GH was not found to have any additional benefit. (Hepatology 2017).

Abstract
Liver cirrhosis (LC) is a major cause of secondary sarcopenia. Sarcopenia makes the prognosis worse; thus, novel therapeutic options for sarcopenia in patients with LC are urgently required as they are currently limited. In this retrospective study, 158 patients with LC were screened, and 35 of those patients who were treated with L‐carnitine for more than 6 months and for whom skeletal muscle mass changes could be evaluated by computer tomography were enrolled. Of the 158 patients, 79 patients who did not receive L‐carnitine supplementation served as controls. Cases and controls were propensity score matched for age, sex, presence of hepatocellular carcinoma, and branched chain amino acid administration, and changes in skeletal muscle mass and clinical data were compared. The 35 patients who received L‐carnitine supplementation and 35 propensity score‐matched patients who did not receive carnitine supplementation comprised the final enrollment. Compared with control patients, patients who received L‐carnitine had significantly worse liver function, which is associated with rapid progress of skeletal muscle depletion. However, loss of skeletal muscle mass was significantly suppressed in patients receiving L‐carnitine, and a significant effect was observed in patient subgroups stratified by age, sex, presence of hepatocellular carcinoma, and branched chain amino acid administration. The change ratios of most laboratory data, including vitamin D and insulin‐like growth factor 1 levels, were similar in the two groups, but ammonia levels were significantly less in those receiving L‐carnitine. However, even in patients receiving L‐carnitine but not showing an ammonia decrease, loss of skeletal muscle was significantly suppressed. Conclusion: L‐carnitine suppresses loss of skeletal muscle mass and may therefore be a novel therapeutic option for sarcopenia in patients with LC. (Hepatology Communications 2018; 00:000‐000)

Abstract
Cirrhosis represents the final stage of chronic liver damage, which can be due to different factors such as alcohol, metabolic syndrome with liver steatosis, autoimmune diseases, drugs, toxins, and viral infection, among others. Nowadays, cirrhosis is an important health problem and it is an increasing cause of morbidity and mortality, being the 14th most common cause of death worldwide. The physiopathological pathways that lead to fibrosis and finally cirrhosis partly depend on the etiology. Nevertheless, some common features are shared in this complex mechanism. Recently, it has been demonstrated that cirrhosis is a dynamic process that can be altered in order to delay or revert fibrosis. In addition, when cirrhosis has been established, insulin-like growth factor-1 (IGF-1) deficiency or reduced availability is a common condition, independently of the etiology of chronic liver damage that leads to cirrhosis. IGF-1 deprivation seriously contributes to the progressive malnutrition of cirrhotic patient, increasing the vulnerability of the liver to establish an inflammatory and oxidative microenvironment with mitochondrial dysfunction. In this context, IGF-1 deficiency in cirrhotic patients can justify some of the common characteristics of these individuals. Several studies in animals and humans have been done in order to test the replacement of IGF-1 as a possible therapeutic option, with promising results.

Abstract
BACKGROUND AND AIM Insulin-like growth factor-1 (IGF-1) and C-reactive protein (CRP) are produced mainly by the liver; the output of these markers in response to inflammatory processes may be affected in patients with hepatic dysfunction. This may explain the differences in IGF-1 and CRP values in patients with non-portal and portal hypertension ascites. We aimed to evaluate serum and ascitic fluid IGF-1 and CRP as diagnostic markers in the differential diagnosis of benign and malignant ascites. METHODS In this prospective study, 398 consecutive patients with ascites were included. Serum and ascitic fluid levels of IGF-1 and CRP were measured using an enzyme-linked immunosorbent assay. RESULTS Patients were divided into group 1, due to benign ascites (n = 324), and group 2, due to malignant ascites (n = 74). Serum and ascitic IGF-1 were significantly increased in malignant ascites than benign ascites group [305 ± 65.7 ng/mL vs 95 ± 53.8 ng/mL; P < 0.001 and 288 ± 54.7 ng/mL vs 83.2 ± 36.7 ng/mL; P < 0.001], respectively. Serum and ascitic CRP were significantly higher in malignant ascites than benign ascites patients [12.8 ± 6.3 mg/mL vs 6.1 ± 4.9 mg/mL; P < 0.001 and 5.1 ± 2.2 mg/mL vs 1.6 ± 1.3 mg/mL; P < 0.001], respectively. At a cutoff value of 309.4 ng/mL and 7.8 mg/mL, serum IGF-1 and CRP had (95.1%, 81%) sensitivity and (88.6%, 75.5%) specificity for detecting malignant ascites [area under the curve: 0.932, 0.845], respectively. At a cutoff value of 291.6 ng/mL and 2.6 mg/mL, ascitic IGF-1 and CRP had (94.6%, 84%) sensitivity and (83.2%, 80.3%) specificity for detecting malignant ascites (area under the curve: 0.911, 0.893) correspondingly. CONCLUSION Elevated serum and ascitic fluid IGF-1 and CRP levels were associated with malignant ascites.

Abstract
Chronic liver diseases (CLDs) encompass a wide range of illnesses, including nonalcoholic fatty liver disease, nonalcoholic steatohepatitis, and viral hepatitis. Deterioration of liver capacity, with subsequent progression into cirrhosis and hepatocellular carcinoma (HCC), ultimately leads to a further decrease in the hepatic reserve. The Child-Turcotte-Pugh scoring system is the standard tool for assessing underlying liver reserve capacity in routine practice and in clinical trials of CLD and HCC. In this review, we highlight the clinical significance of insulin-like growth factor-I (IGF-I) and the growth hormone (GH) signaling pathway in HCC. IGF-I could be a marker for liver reserve capacity in CLDs and HCC in clinical practice. This approach could improve the risk assessment and stratifications of patients on the basis of their underlying liver reserve, either before active treatment in routine practice or before they are enrolled in clinical trials.

Abstract
Background Intestinal barrier dysfunction is not only the consequence of liver cirrhosis, but also an active participant in the development of liver cirrhosis. Previous studies showed that external administration of insulin-like growth factor 1 (IGF-1) improved intestinal barrier function in liver cirrhosis. However, the mechanism of IGF-1 on intestinal barrier in liver cirrhosis is not fully elucidated. The present study aims to investigate the mechanisms of IGF-1 improving intestinal barrier function via regulating tight junctions in intestines. Methods We used carbon tetrachloride induced liver cirrhotic rats to investigate the effect of IGF-1 on intestinal claudin-1 and occludin expressions, serum alanine transaminase (ALT) and aspartate transaminase (AST) levels, severity of liver fibrosis, portal pressures, enterocytic apoptosis and lipopolysaccharides (LPS) levels in portal vein. The changes of IGF-1 in serum during the development of rat liver cirrhosis were also evaluated. Additionally, we assessed the effect of IGF-1 on claudin-1 and occludin expressions, changes of transepithelial electrical resistance (TEER) and apoptosis in Caco-2 cells to confirm in vivo findings. Results Serum IGF-1 levels were decreased in the development of rat liver cirrhosis, and external administration of IGF-1 restored serum IGF-1 levels. External administration of IGF-1 reduced serum ALT and AST levels, severity of liver fibrosis, LPS levels in portal vein, enterocytic apoptosis and portal pressure in cirrhotic rats. External administration of IGF-1 increased the expressions of claudin-1 and occludin in enterocytes, and attenuated tight junction dysfunction in intestines of cirrhotic rats. LPS decreased TEER in Caco-2 cell monolayer. LPS also decreased claudin-1 and occludin expressions and increased apoptosis in Caco-2 cells. Furthermore, IGF-1 attenuated the effect of LPS on TEER, claudin-1 expression, occludin expression and apoptosis in Caco-2 cells. Conclusions Tight junction dysfunction develops during the development of liver cirrhosis, and endotoxemia will develop subsequently. Correspondingly, increased endotoxin in portal system worsens tight junction dysfunction via decreasing intestinal occludin and claudin-1 expressions and increasing enterocytic apoptosis. Endotoxemia and intestinal barrier dysfunction form a vicious circle. External administration of IGF-1 breaks this vicious circle. Improvement of tight junctions might be one possible mechanism of the restoration of intestinal barrier function mediated by IGF-1.

Abstract
Acetaminophen (APAP) is widely used in the treatment of pain. Toxic doses of APAP cause acute liver failure, but therapeutic doses are believed to be safe. The purpose of this study is to investigate the effects of administration of subtoxic doses of APAP on liver and blood levels of insulin-like growth factor-1 (IGF-1) in rats. Low dose (100 mg/kg) and high dose (250 mg/kg) of APAP were intraperitoneally injected into Wistar albino rats. Following administration of therapeutic doses of APAP, there were no significant changes in serum transaminases and liver glutathione levels. Both doses of APAP induced a decrease in liver and blood levels of IGF-1 when compared with the controls. There was no significant difference in liver IGF-1 levels between the high-dose and low-dose APAP groups; however, there was a significant difference in blood IGF-1 levels between both the groups. The histological examination showed that low dose of APAP induced mild degree of structural change, while high dose of APAP induced severe structural damage. In conclusion, these results suggest that blood IGF-1 levels may have a value in predicting hepatic damage resulting from therapeutic doses of APAP.

Abstract
BACKGROUND IGF-I and IGFBP-3 are part of IGF system and, due to their predominantly hepatic synthesis, they seem to correlate with hepatic dysfunction intensity. AIMS To investigate the significance of IGF-I and IGFBP-3 in patients with decompensated liver disease. MATERIAL AND METHODS Cross-sectional study that included cirrhotic patients admitted to hospital due to complications of the disease, in whom IGF-I and IGFBP-3 serum levels were measured by chemiluminescence. RESULTS Seventy-four subjects with a mean age of 53.1 ± 11.6 years were included in the study, 73% were males. IGF-I levels were positively correlated with IGFBP-3 and albumin, and negatively correlated with Child-Pugh, MELD, creatinine, INR and aPTT ratio. IGFBP-3 levels were positively correlated with IGF-I and albumin, and negatively correlated with Child-Pugh, MELD, creatinine, INR, total bilirubin and aPTT ratio. Significantly lower scores of IGF-I and IGFBP-3 were observed in patients with higher MELD values and higher Child-Pugh classes (P < 0.05). CONCLUSIONS In cirrhotic patients admitted to hospital due to complications of the disease, IGF-I and IGFBP-3 serum levels were associated with variables related to liver dysfunction and to more advanced liver disease. The levels of these markers seem to undergo little influence from other clinical and laboratory variables, therefore mainly reflecting hepatic functional status.

Abstract
BACKGROUND Insulin-like growth factor is a polypeptide with endocrine, autocrine and paracrine effects which its structure is similar to the insulin molecule. While various tissues secrete IGF-1, 90% of the circulating IGF-1 is secreted by liver. Cirrhosis of liver is a condition accompanied by decreased level of IGF-1, in which the level of IGF-1 may be further decreased thorough the progression of the disease. OBJECTIVES The aim of the present study was to demonstrate the relation between the IGF-1 levels and severity of liver disease according to Child- Pugh and Model for end stage liver diseases (MELD) Scores. PATIENTS AND METHOD This was a descriptive-analytic cross sectional study performed on patients with cirrhosis admitted to gastroenterology clinic of Imam Khomeini Hospital in Tehran, Iran during the years 2007-2008. The diagnosis was based on liver biopsy. Initially for all patients, laboratory investigations including IGF-1, CBC, liver Enzymes, Alkaline phosphates, serum Albumin, Creatinine, direct and total Bilirubin were conducted. Also ultrasound and endoscopy were performed for evaluation of ascites and varices. RESULTS 100 patients with cirrhosis with a male to Female ratio of 63:37 and a mean age of 44.4 ± 15 years were enrolled in the study. Median IGF-1 was 92.95 ± 91.51 ng/mL. 14 patients (14%) had IGF-1 within normal limits while 86 patients (86%) had abnormal IGF-1 levels. In all patients the correlation coefficient between IGF-1 and MELD was -0.317 (P = 0.001) and 0.478 between IGF-1 and Child- Pugh (P < 0.001). CONCLUSIONS Our findings showed that IGF-1 can be used as an index for evaluating the severity of cirrhosis; also it can be used for determining the severity of the disease, when liver biopsy is not possible.

Abstract
Diabetes and insulin resistance frequently cause liver damage. Diabetes also causes reduction in liver and blood IGF-1 levels. We investigated the relation between liver damage and IGF-1 levels in diabetic rats. Fourteen Wistar albino rats were divided into control and diabetic groups. Diabetes was induced by streptozotocin. Rats were sacrificed for biochemical and histologic examinations 2 weeks after streptozotocin injection. Serum and liver IGF-1 levels were decreased, liver malondialdehyde (MDA) levels were increased, glutathione peroxidase (GPx) enzymes activities were decreased and serum alanine aminotransferase (ALT) levels were increased in diabetic group. Microscopic examination of liver revealed that normal tissue organization was disrupted in streptozotocin-induced diabetic rats. There was a strongly positive correlation between blood glucose levels and liver injury, and blood and liver IGF-1 levels. There was a strongly negative correlation between blood IGF-1 levels and hepatic injury. Our results suggest that reduction of blood IGF-1 levels correlates with hepatic injury and circulating IGF-1 levels may have predictive value for determining hepatic damage that results from diabetes. In addition, circulating IGF-1 levels are correlated with glutathione levels and the oxidative stress status of diabetic rat liver.

Abstract
OBJECTIVES Investigate the prognostic value of serum insulinlike growth factor-1 (IGF-1) and its binding protein 3 (IGFBP-3) in pediatric patients with liver cirrhosis, and investigate the correlation between these parameters and other available prognostic factors including Child-Pugh scoring, Pediatric End-Stage Liver Disease, and Mayo End-Stage Liver Disease scoring. MATERIALS AND METHODS This prospective, case-controlled study was done at the Nemazee hospital for 12 months from August 2009 to August 2010. It included 45 pediatric patients (< 18 years) diagnosed with liver cirrhosis and 38 healthy age and sex-matched controls. The extent and severity of the liver disease was evaluated by the Child-Pugh classification and Pediatric End-Stage Liver Disease/Mayo End-Stage Liver Disease scores. Serum levels of IGF-1 and IGFBP-3 were determined and were compared to controls and their correlation with Child-Pugh and Pediatric End-Stage Liver Disease/Mayo End-Stage Liver Disease scores were investigated. RESULTS The most-common cause of liver cirrhosis was biliary atresia being found in 11 patients (24.4%) followed by tyrosinemia in 8 (17.8%). IGF-1 serum levels were significantly lower in cirrhotic patients compared with controls (3.85 ± 3.69 nmol/L vs 41.79 ± 16.03 nmol/L; P < .001). Serum levels of IGFBP-3 also were significantly lower in patients with liver cirrhosis compared with healthy controls (46.66 ± 30.57 nmol/L vs 205.63 ± 25.52 nmol/L; P < .001). Serum levels of IGF-1 were significantly lower in patients with stage B (P = .047) and C (P = .036) of Child-Pugh classification compared with stage A. Serum levels of IGF-1 (r ≈ 0.227; P = .034) and IGFBP-3 (r ≈ 0.389; P = .008) were negatively correlated with Pediatric End-stage Liver Disease / Mayo End-stage Liver Disease scores. CONCLUSIONS The serum levels of IGF-1 and IGFBP-3 are decreased in children with liver cirrhosis. The stage of liver dysfunction is correlated to serum levels of IGF-1 and IGFBP-3 in children. Thus, these 2 factors can be used for assessing the prognosis and outcome in those children with liver cirrhosis.

Abstract
Insulin-like growth factor I (IGF-I) is a polypeptide hormone produced mainly by the liver in response to the endocrine GH stimulus, but it is also secreted by multiple tissues for autocrine/paracrine purposes. IGF-I is partly responsible for systemic GH activities although it possesses a wide number of own properties (anabolic, antioxidant, anti-inflammatory and cytoprotective actions). IGF-I is a closely regulated hormone. Consequently, its logical therapeutical applications seems to be limited to restore physiological circulating levels in order to recover the clinical consequences of IGF-I deficiency, conditions where, despite continuous discrepancies, IGF-I treatment has never been related to oncogenesis. Currently the best characterized conditions of IGF-I deficiency are Laron Syndrome, in children; liver cirrhosis, in adults; aging including age-related-cardiovascular and neurological diseases; and more recently, intrauterine growth restriction. The aim of this review is to summarize the increasing list of roles of IGF-I, both in physiological and pathological conditions, underlying that its potential therapeutical options seem to be limited to those proven states of local or systemic IGF-I deficiency as a replacement treatment, rather than increasing its level upper the normal range.

Abstract
Insulin-like growth factors (IGFs) play an essential role in growth and development, as well as in the overall cellular regulation and metabolism in the human body. In chronic liver disease, IGF levels are decreased, and the circulating levels correlate to the extent of hepatocellular dysfunction. Patients with cirrhosis are characterised by a variety of metabolic disturbances, including nutritional and metabolic complications such as insulin resistance, malnutrition, osteopenia and hypogonadism, all related to IGF-I deficiency. The complex process of hepatic fibrogenesis and the systemic consequences in cirrhosis are only partly understood. Disruption of the growth hormone (GH)-IGF-I axis seems to be closely associated with the development of liver disease, and treatment with recombinant human IGF (rhIGF)-I has been shown to halt, and even reverse, the fibrotic degeneration. IGF-I in itself has a strong antifibrotic effect that acts directly through the GH/IGF system and indirectly by the regulation of hepatoprotective and profibrogenic factors. It is most likely that IGF-I deficiency contributes to the diverse metabolic complications of cirrhosis. At present, liver transplantation remains the only efficient treatment of cirrhosis, and thus new methods of managing the disease are called for. RhIGF-I supplementation and IGF-I gene therapy may represent future perspectives of treatment.

Abstract
Due to the widespread clinical use of imaging modalities such as ultrasonography, computed tomography and magnetic resonance imaging (MRI), previously unsuspected liver masses are increasingly being found in asymptomatic patients. This review discusses the various characteristics of the most common solid liver lesions and recommends a practical approach for diagnostic workup. Likely diagnoses include hepatocellular carcinoma (the most likely; a solid liver lesion in a cirrhotic liver) and hemangioma (generally presenting as a mass in a non-cirrhotic liver). Focal nodular hyperplasia and hepatic adenoma should be ruled out in young women. In 70% of cases, MRI with gadolinium differentiates between these lesions. Fine needle core biopsy or aspiration, or both, might be required in doubtful cases. If uncertainty persists as to the nature of the lesion, surgical resection is recommended. If the patient is known to have a primary malignancy and the lesion was found at tumor staging or follow up, histology is required only when the nature of the liver lesion is doubtful.

Abstract
UNLABELLED Patients with liver cirrhosis exhibit early onset of gluconeogenesis after short-term fasting. This accelerated metabolic reaction to starvation may underlie their increased protein requirements and muscle depletion. A randomized controlled trial was conducted to test the hypothesis that provision of a late-evening nutritional supplement over a 12-month period would improve body protein stores in patients with cirrhosis. A total of 103 patients (68 male, 35 female; median age 51, range 28-74; Child-Pugh grading: 52A, 31B, 20C) were randomized to receive either daytime (between 0900 and 1900 hours) or nighttime (between 2100 and 0700 hours) supplementary nutrition (710 kcal/day). Primary etiology of liver disease was chronic viral hepatitis (67), alcohol (15), cholestatic (6), and other (15). Total body protein (TBP) was measured by neutron activation analysis at baseline, 3, 6, and 12 months. Total daily energy and protein intakes were assessed at baseline and at 3 months by comprehensive dietary recall. As a percentage of values predicted when well, TBP at baseline was similar for the daytime (85 +/- 2[standard error of the mean]%) and nighttime (84 +/- 2%) groups. For the nighttime group, significant increases in TBP were measured at 3 (0.38 +/- 0.10 kg, P = 0.0004), 6 (0.48 +/- 0.13 kg, P = 0.0007), and 12 months (0.53 +/- 0.17 kg, P = 0.003) compared to baseline. For the daytime group, no significant changes in TBP were seen. Daily energy and protein intakes at 3 months were higher than at baseline in both groups (P < 0.0001), and these changes did not differ between the groups. CONCLUSION Provision of a nighttime feed to patients with cirrhosis results in body protein accretion equivalent to about 2 kg of lean tissue sustained over 12 months. This improved nutritional status may have important implications for the clinical course of these patients.

Abstract
BACKGROUND/AIMS Previous studies reported decreased serum IGF-1 levels in cirrhosis. We aimed to correlate GH-stimulated IGF-1 responses with both MELD and Child-Pugh scores and determine the impact of portal hypertension and nutrition on IGF-1 responses. METHODS Fifty-three patients (56+/-2 yrs) with cirrhosis were enrolled. Serum IGF-1 levels were measured by RIA before and 24h after a single injection of GH (0.06 mg/kg). RESULTS Compared to controls, basal IGF-1 levels were significantly decreased in patients with cirrhosis (17.3+/-6.3 vs 13.6+/-5.1, P<0.001). Increments in IGF-1 levels were significantly lower in cirrhotic patients (controls: 133% vs 49% in MELD score <10, 38% in MELD score 11-18, and 13% in MELD score 19-24, p<0.001). 37% of patients had blunted IGF-1 responses. Increments in IGF-1 levels correlated with albumin (r=0.6), portal congestive index (r=0.4), and MAMC (r=0.25). By multivariate analysis, only CP (OR 5.7) and MELD scores (OR 4.5) accurately differentiated between blunted or non-blunted IGF-1 responses and not portal hypertension (OR 0.9) or malnutrition (OR 1.35). CONCLUSIONS Cirrhosis is associated with low IGF-1 levels and an attenuated response to exogenous GH. These findings correlate better with the extent of hepatic dysfunction rather than the presence of portal hypertension or malnutrition.

Abstract
AIM In patients with cirrhosis, endotoxemia is frequent and the vitally important capacity for urea synthesis is impaired. The patients' mortality of infection is markedly increased, which could be related to adverse metabolic effects of endotoxins. The effects of endotoxins on in vivo urea synthesis and on urea cycle genes during cirrhosis are unknown. METHODS We examined the effects of a low dose of 0.5 mg/kg ip lipopolysaccharide (LPS) on the basal urea nitrogen synthesis rate (UNSR), the capacity of urea nitrogen synthesis (CUNS), liver tissue mRNA levels of urea cycle enzyme genes, and on the metabolic liver function measured by the galactose elimination capacity (GEC) in rats with cirrhosis induced by bile duct ligation and in control animals. RESULTS LPS and cirrhosis + LPS decreased UNSR by 40% (P < 0.05). Cirrhosis and LPS each tended to decrease CUNS and cirrhosis + LPS decreased CUNS by 40% (P < 0.05). Cirrhosis and LPS each decreased the mRNA level of the gene for the flux-generating urea cycle enzyme carbamoyl phosphate synthetase (CPS) and the mRNA for the rate-limiting urea cycle enzyme arginine succinate synthetase (ASS) (P < 0.05). Cirrhosis + LPS left the mRNA level of CPS unchanged and decreased that of ASS (P < 0.05). The GEC did not differ among the study groups. CONCLUSION Endotoxemia in rats with experimental cirrhosis markedly impaired the ability of the animals' livers to synthesize urea, suggesting a pathophysiological mechanism underlying the severe consequences of endotoxemia in human cirrhosis.

Abstract
BACKGROUND/AIMS Insulin-like growth factor I (IGF-I) is an anabolic hormone synthesized in the liver whose levels decrease sharply in liver cirrhosis. METHODS We conducted a randomized double-blind placebo-controlled clinical trial to evaluate the effect of subcutaneous administration of IGF-I (20 microg/kg/day with dose escalation to 50-100 microg/kg/day) for 4 months in patients with alcoholic or primary biliary cirrhosis (PBC) and subnormal IGF-I levels. Eight alcoholics and one PBC entered the placebo group and seven alcoholics and two PBC the treatment group. Biochemistry, body composition, muscle mass and strength, and resting energy expenditure (REE) were evaluated. RESULTS Total serum IGF-I and IGF-I/IGFBP-3 ratio (a surrogate marker of IGF-I biovailability) increased in the treatment group but IGF-I values still remained below normal limits in the treated patients. No differences were observed in body composition, muscle strength or muscle mass between groups. However, IGF-I therapy increased significantly serum albumin (P = 0.038) and this improvement correlated positively with variation of IGF-I/IGFBP-3 ratio. IGF-I treatment also tended to increase REE (P = 0.085); this difference was significant (P = 0.049) in the subgroup of alcoholic patients. CONCLUSIONS A short course of IGF-I increased albumin levels and tended to improve energy metabolism in liver cirrhosis. These findings warrant larger clinical trials to assess the clinical benefit of IGF-I in cirrhotic patients.

Abstract
OBJECTIVE The liver plays a central role in insulin-like growth factor (IGF) homeostasis providing the majority of circulating IGF-I and some of its binding proteins (IGFBPs). In liver cirrhosis the IGF axis is severely disturbed, and these alterations are associated with reduced IGF-I, IGFBP-3 but elevated IGFBP-1 serum levels. METHODS By Northern blotting and in situ hybridization (ISH), hepatic expression of IGF-I and of IGFBP was studied in a rat model of liver cirrhosis induced by thioacetamide. RESULTS ISH revealed a homogeneous distribution of IGFBP-1, IGFBP-4 and IGF-I mRNA over hepatic parenchyma in normal and cirrhotic liver. Fibrous septa of cirrhotic liver were IGFBP-1 mRNA negative, whereas IGFBP-4 and IGF-I transcripts were detected in single cells. In normal liver, IGFBP-3 mRNA was distributed within nonparenchymal cells of the hepatic lobule and in the wall of the portal vein. In cirrhotic liver, IGFBP-3 transcripts were abundant in mesenchymal cells of fibrous tissue. IGFBP-3 mRNA expression was also prominent in cells at the septal-nodular interface most likely representing monocyte infiltration. IGFBP-3 mRNA expression was reduced in nonparenchymal liver cells located more distantly from the septal-nodular interface in the cirrhotic nodule that correlated with reduced IGFBP-3 mRNA expression observed in Kupffer cells (KC) and sinusoidal endothelial cells (SEC) isolated from macronodular cirrhotic livers. CONCLUSION Cirrhosis is accompanied by an altered spatial expression of IGFBP-3 in liver tissue, which is characterized by decreased levels of IGFBP-3 mRNA in KC and SEC, but elevated IGFBP-3 expression in myofibroblast-like cells and inflammatory infiltrate.

Abstract
Chronic and excessive ethanol intake in rats results in low levels of hepatic retinoic acid (RA) either by inhibiting the biosynthesis of RA or by enhancing its catabolism of RA. Chronic ethanol intake also decreases both hepatic expression of insulin-like growth factor-I (IGF-I) and plasma IGF-I concentration in rats. It is not known whether RA supplementation in alcohol-fed rats can restore plasma IGF-I concentrations and hepatic IGF-I expression. In the present study, we examined both plasma IGF-I level and hepatic IGF-I mRNA expression in alcohol-fed rats with or without RA (100 microg/kg body weight) supplementation for 6 mo. Hepatic IGF-I mRNA levels and plasma IGF-I concentration were decreased (84 and 29%, respectively) significantly in alcohol-fed rats compared with the control. In contrast, RA supplementation in ethanol-fed rats partially restored both hepatic IGF-I mRNA levels and plasma IGF-I concentration compared with rats fed ethanol alone. These data suggest that alcohol-impaired hepatic RA status contributes to the decreased plasma IGF-I level and hepatic IGF-I expression in alcoholics.

Abstract
AIM: To investigate the relationship between insulin-like growth factor-I, -II (IGF-I and IGF-II), IGF-binding protein 3 (IGFBP-3) and Child-Pugh score in patients with liver cirrhosis, and to search for potential clinical markers of liver function.
METHODS: Forty-four patients with advanced liver cirrhosis of viral origin were divided into 3 groups according to severity of cirrhosis (Child-Pugh score) and 38 healthy subjects served as controls. Serum levels of IGF-I, IGF-II and IGFBP-3 were measured by immunoradiometric assay.
RESULTS: Serum IGF-I, IGF-II and IGFBP-3 levels were significantly lower in patients with cirrhosis than in controls, and serum concentrations of IGF-I, IGF-II and IGFBP-3 were associated with the severity of liver dysfunction, and dropped sharply during the progression of liver failure. Among these 3 parameters, serum IGF-II was the most sensitive and effective indicator for liver dysfunction. Concentrations of IGF-I < 30 ng/mL, IGF-II < 200 ng/mL and IGFBP-3 < 6 ng/mL implied a negative prognosis for patients with liver cirrhosis.
CONCLUSION: Serum IGF-I, IGF-II and IGFBP-3 may provide a new dimension in the assessment of liver dysfunction. Combined detection of serum IGF-I, IGF-II and IGFBP-3 with Child-Pugh score is more effective in predicting prognosis than Child-Pugh score alone.

Abstract
Perturbations in sex hormones occur in adults with liver disease; however, little is known about how liver disease affects hormone levels in children. To address this issue, we recruited 19 patients with portal hypertension and 21 non-hormone-deficient short children as controls. Serum sex hormones, sex hormone binding globulin (SHBG), IGF-I, IGFBP-3, gonadotropins, and thyroid hormones were measured; growth and pubertal status were recorded. There was no significant difference between groups for any of the sex hormones, SHBG, gonadotropins, or thyroid hormones. In contrast, IGF-I and IGFBP-3 were significantly lower among patients than controls, despite the fact that height SDS for the control group was significantly lower. We conclude from this cross-sectional study that children with portal hypertension do not have clinical evidence of growth failure or abnormal puberty, despite subtle changes in the growth axis.

Abstract
SUMMARY Insulin-like growth factors (IGFs) and IGF-binding proteins (IGFBPs) may play an important role in tumor proliferation. This study aimed to investigate the IGF system in children with acute leukemia prior to and after hematological stem cell transplantation (HSCT). In 51 patients (AML n=27; ALL n=24; mean age 11.2+/-4.8 years), serum parameters (IGF-I,-II, IGFBP-2,-3) were investigated up to 18 months after HSCT by RIA. Patients with AML showed a significant increase of IGFBP-2 up to 100 days after HSCT (mean +/-s.d. prior to HSCT: 3.2+/-3.6 SDS vs 100 days after HSCT: 5.3 degrees +/-3.4 SDS, P=0.005). Furthermore, IGF-I and IGFBP-3 were significantly decreased (IGF-I: -0.3+/-1.5 vs -0.7 +/-1.2 SDS, P=0.001; IGFBP-3: -0.3+/-1.1 vs -1.0+/-1.1 SDS, P=0.02). Children with AML showed significantly higher IGFBP-2 (P=0.04) and significantly lower IGF-I (P=0.03) and IGFBP-3 (P=0.05) levels than children with ALL at day 100 after HSCT. We conclude that children with acute leukemia show important changes in the IGF system after HSCT. In particular, IGFBP-2 was significantly elevated at day 100 after HSCT. Increased IGFBP-2 and decreased IGF-I and IGFBP-3 may be associated with the increased proliferation rate of transplanted bone marrow.

Abstract
AIM To study the expression of IGF-1 and IGF-1R and its intervention by interleukin-10 in the course of experimental hepatic fibrosis. METHODS Hepatic fibrosis was induced in rats by carbon tetrachloride intoxication and liver specimens were taken from the rats administered CCl4 with or without IL-10 treatment and the animals of the control group. Immunoreactivities for insulin-like growth factor-1 (IGF-1) and IGF-1 receptor(IGF-1R) were demonstrated by immunohistochemistry, and their intensities were evaluated in different animal groups. RESULTS The positive levels for IGF-1 and IGF-1R were increased with the development of hepatic fibrosis, with the positive signals localized in cytoplasm and/or at the plasmic membrane of hepatocytes. The positive signals of IGF-1 and IGF-1R were observed more frequently (P<0.01) in the CCl4-treated group (92.0 % and 90.0 %) compared to those in the control group. The positive signals decreased significantly (P<0.05) in IL-10-treated group. The responses in IGF-1 and IGF-1R expression correlated with the time of IL-10 treatment. CONCLUSION The expression of IGF-1 and IGF-1R immunoreactivities in liver tissue seems to be up-regulated during development of hepatic fibrosis induced by CCl(4), and exogenic IL-10 inhibits the responses.

Abstract
OBJECTIVE To investigate anterior pituitary function (adrenal, somatotropic, thyroid and gonadal axes, and prolactin) in relation to the Child-Pugh score in male patients with alcoholic and virus-related liver cirrhosis. METHOD Anterior pituitary function was evaluated in 52 male cirrhotics (26 Child-Pugh class A (CPA), 16 Child-Pugh class B (CPB) and 10 Child-Pugh class C (CPC)) by a combined pituitary stimulation test, and was compared with 50 age-matched controls. RESULTS A normal cortisol response to corticotropin-releasing hormone (CRH) stimulation was demonstrated in 57.6% of CPA patients, 31.1% of CPB patients and 20% of CPC patients, while basal levels of adrenocorticotropic hormone (ACTH) and cortisol in cirrhotics were comparable to those in controls. Levels of basal growth hormone (P < 0.001) and stimulated growth hormone (P < 0.01) were significantly higher in cirrhotics compared with controls, while levels of insulin-like growth factor 1 (IGF-1) were significantly lower (P < 0.001). Basal prolactin levels were elevated significantly in CPC patients (P < 0.01), while stimulated prolactin as well as basal and stimulated thyroid-stimulating hormone (TSH) levels were comparable. Basal luteinizing hormone levels were significantly higher in CPA (P < 0.001) and CPB (P < 0.001) patients, and stimulated luteinizing hormone levels were significantly lower in CPC patients than in controls (P < 0.005). Basal and stimulated follicle-stimulating hormone (FSH) levels were comparable in all groups. Child-Pugh score was correlated positively to prolactin and was correlated negatively to IGF-1, stimulated luteinizing hormone and free testosterone. CONCLUSIONS In cirrhotics, the hypothalamic-pituitary-adrenal and -gonadal axes and prolactin secretion are impaired. Growth hormone response to growth hormone-releasing hormone (GHRH) is accelerated in cirrhotics. Thus, elevated basal and stimulated levels of growth hormone probably reflect compensation for low levels of IGF-1, which are associated with deteriorating liver function. The aetiology of cirrhosis was found to have no influence on the degree of alteration of the hypothalamic-pituitary-glandular axes.

Basal luteinizing hormone levels were significantly higher in CPA (P < 0.001) and CPB (P < 0.001) patients, and stimulated luteinizing hormone levels were significantly lower in CPC patients than in controls (P < 0.005). Basal and stimulated follicle-stimulating hormone (FSH) levels were comparable in all groups. Child-Pugh score was correlated positively to prolactin and was correlated negatively to IGF-1, stimulated luteinizing hormone and free testosterone. CONCLUSIONS In cirrhotics, the hypothalamic-pituitary-adrenal and -gonadal axes and prolactin secretion are impaired. Growth hormone response to growth hormone-releasing hormone (GHRH) is accelerated in cirrhotics. Thus, elevated basal and stimulated levels of growth hormone probably reflect compensation for low levels of IGF-1, which are associated with deteriorating liver function. The aetiology of cirrhosis was found to have no influence on the degree of alteration of the hypothalamic-pituitary-glandular axes.

Abstract
BACKGROUND/AIMS The liver is the central organ of the endocrine growth hormone/insulin-like growth factor I (GH/IGF-I) axis and cirrhosis effects a state of acquired GH resistance. Low IGF-I levels are associated with adverse clinical outcomes in cirrhotic patients and may be pathogenic to the complications of cirrhosis. We examined the impact of cirrhosis on hepatic mRNA and serum protein levels for the GH receptor (GHR)/binding protein (GHBP), IGF-I, IGF binding protein (IGFBP)-3 and the acid-labile subunit (ALS). METHODS Fifty patients with cirrhosis were studied and liver tissue was obtained from 18. Gene expression was assessed by Northern analysis and serum protein levels by immunoassay. RESULTS In cirrhotic liver GHR mRNA and GH binding to microsomal membranes were decreased by 61 and 56%, respectively. Serum GHBP levels were decreased only in severe disease, not correlating with GHR mRNA or GH binding. Hepatic IGF-I and ALS mRNA were significantly decreased by 84 and 68%, respectively, in parallel with serum protein, suggesting transcriptional regulation. Hepatic IGFBP-3 mRNA was unchanged but low serum IGFBP-3 suggested post-transcriptional regulation. CONCLUSIONS The decreased mRNA and serum levels for the GH-dependent, hepatocyte produced proteins IGF-I and ALS confirm the importance of GH receptor loss to the GH resistance of cirrhosis.

Abstract
The protein synthetic activity of the liver is diminished in cirrhosis. The aim of this study was to investigate possible changes in the serum IGF-IGFBP system among patients with alcoholic liver cirrhosis (ALC). The results obtained demonstrated that serum IGF-I and IGF-II concentrations were significantly lower in patients with ALC than in healthy persons (P=0.0008 for IGF-I and 0.0002 for IGF-II). The IGFBP profile was markedly altered and the 34 kDa IGFBP from patients had higher affinity towards 125I-IGF-II compared to the 34 kDa IGFBP of control individuals. Moreover, the 40-45 kDa IGFBP (in isolated complex with 125I-IGF-II) exhibited diminished interaction with concanavalin A, wheat germ, and breadfruit lectins. Modification of the glyco-component of the 40-45 kDa IGFBP seems to be an early event in ALC since change in reactivity towards lectins was noticed in patients with ALC classified as Child score A, whose serum IGF-I and IGF-II levels were within reference limits (the existence of carbohydrate microheterogeneity of this IGFBP was also assessed by lectin-affinity electrophoresis). It is possible that these biochemical alterations may affect the functional activity of the IGFs by changing the dynamics and distribution of these growth factors in the organism.

Abstract
To establish their ability to predict malnutrition, irregular feeding, alcoholic intake, derangement of social and familial links and organic complications (liver cirrhosis) were assessed in 181 hospitalized male alcoholic. BMI was under 18.5 kg/m(2) in 8.9%, between 18.5-20 kg/m(2) in 8.9%, 20-25 kg/m(2) in 42%, 25-30 kg/m(2) in 32.2% and over 30 kg/m(2) in 8.2% of patients. Malnutrition was related to the intensity of ethanol intake, development of social or familial problems, irregularity of feeding habits and cirrhosis with ascites. Irregularity of feeding habits was also related to heavy drinking and to social or familial derangement. By logistic regression analysis, the only variables which independently predict malnutrition were irregular feeding habits and liver cirrhosis with ascites. In a second step, irregular feeding was dependent on social or familial troubles and daily intake of ethanol. So, malnutrition related to alcoholism seems multifactorial in its pathogenesis.

Abstract
The aim of this investigation was to determine the total concentrations of the insulin-like growth factors (IGF-I and IGF-II) in the blood serum of patients with liver cirrhosis and to evaluate their association with the condition. Cirrhosis was alcohol induced (n=27), of viral origin (n=17) or due to combined or other causes (n=21) and was moderate or severe in similar numbers of cases (Child A: n=21; Child B: n=21; Child C: n=23). While serum levels of both peptides were lower in patients than in age-matched healthy subjects (n=81), there was considerable overlap into the lower normal range for IGF-I. Moreover, no correlation between disease severity (Child score) and serum IGF-I was observed. Since a total of 78% of the results for IGF-II were outside the normal range (95% confidence interval) and serum concentrations were correlated with Child score (P=0.007), it is suggested that serum IGF-II concentrations may reflect compromised hepatic function more closely than IGF-I.

Abstract
AIM: To determine whether serum vascular endothelial growth factor (VEGF) levels correlates with the severity of liver cirrhosis and whether portal hypertension impacts on the expression of serum VEGF protein.
METHODS: Fifty-three patients (mean age 56 ± 2 years) with HCV (n = 26), HBV (n = 13), and cryptogenic liver cirrhosis (n = 14) (Child-Pugh-s class A: 24, B: 19 and C: 12) and normal renal function constitute the patient population, who were all diagnosed by clinical, histological and radiological findings. Six healthy people and six patients with acute hepatitis served as controls. Severity of liver disease was evaluated by the CP score. Serum levels of IGF-1 and VEGF were measured by radioimmunoassay and ELISA, respectively. Portal hypertension was assessed using pulsed Doppler ultrasound.
RESULTS: The mean serum VEGF levels in all cirrhotic patients (73 ± 58) were significantly lower than those of healthy controls (360 ± 217, P < 0.01) and acute hepatitis (1123 ± 1261, P < 0.01) respectively. No significant difference in median serum VEGF levels were noted among the different Child-Pugh-s classes (class A: median, 49.4 ng/L, range, 21-260 ng/L, Class B: median 59.9 ng/L; range 21-92, and Class C: median 69; range 20-247 ng/L). A significant correlation was noted between serum VEGF and two accurate parameters of portal hypertension: portal blood flow velocity (r = 06) and spleen size (r = 0.55). No correlation was found between VEGF serum levels and serum albumin, IGF-1, platelets count and aminotrasnferases (r = 0.2, r = 0.1, r = 0.2 and r = 0.2, respectively).
CONCLUSION: Circulating VEGF level in patients with liver cirrhosis could not serve as an indicator of the progression of chronic liver disease but rather, they may reflect increased portal hypertension or decreased hepatic regenerative activity or the combination of both.

Abstract
BACKGROUND/AIMS Liver cirrhosis is characterized by high serum growth hormone levels and low serum insulin-like growth factor I and growth hormone-binding protein levels. The present study was designed to characterize the serum profile of growth hormone and growth hormone pharmacokinetics in postnecrotic liver cirrhosis, correlating it with liver function and nutritional states. METHODS Fifteen patients were grouped by the Child-Pugh score (group 1, score of 5 to 8; group 2, score of 9 to 12). Five healthy subjects served as controls. Nutritional status was assessed by the creatinine-height index. Baseline growth hormone, insulin-like growth factor, and growth hormone binding protein were measured, and growth hormone pharmacokinetics was followed for 48 h after administration of subcutaneous recombinant human growth hormone (0.06 mg/kg). RESULTS Trough serum growth hormone (microg/l) was higher in both patient groups (5.3+/-3.6) than in controls (1.0+/-0.3; p<0.01). More pulses were recorded in cirrhotic patients, and mean pulse amplitude (microg/l) was higher in cirrhotic patients than in controls (p<0.01). After subcutaneous recombinant human growth hormone injection, maximal growth hormone was higher in cirrhotic patients and the area under the curve over 24 h was greater (626+/-120) than in controls (330+/-54; p<0.01). Single regression analysis showed a weak correlation of both the Child-Pugh score and the creatinine-height index with the pharmacokinetic parameters. CONCLUSIONS Due to decreased growth hormone clearance, patients with liver cirrhosis have increased trough and peak serum growth hormone levels, as well as lower serum growth hormone binding protein and insulin-like growth factor. Recombinant human growth hormone pharmacokinetics are typical of a high hepatic extraction substance administered to patients with liver disease and portal hypertension, and this may be relevant to the further use of growth hormone therapy.

Abstract
Our aim was to study the prognostic value of growth hormone (GH) -stimulated insulin-like growth factor-I (IGF-I) and IGF-binding protein-3 (IGFBP-3) generation in patients with compensated [group 1 (N = 8) with a Child-Pugh (CP) score of 5-8] and decompensated postnecrotic liver cirrhosis [group 2 (N = 7) with a CP score of 9-12]. Serum levels of IGF-I, GH-binding protein (GHBP), and IGFBP-3 were measured before and 24 hr after a single subcutaneous injection of recombinant human GH (rhGH, 0.14 units/kg). Patients (mean age 56 years) were followed prospectively for three years. Six patients (40%) died during the follow-up period, of whom half had a CP score <9. Mean serum IGF-I levels 24 hr after rhGH injection (group 1 vs group 2, 17.4 +/- 6.8 vs 7.4 +/- 0.7 nmol/liter) predicted survival with 93% accuracy. Levels <10 nmol/liter portended a poor prognosis, with 15% survival at one year, whereas levels >10 nmol/liter had a 100% survival rate at one and two years, respectively. Baseline IGF-I (9.98 +/- 2.0 vs 6.38 +/- 0.8 nmol/liter), GHBP (9.2 +/- 3 vs 5.7 +/- 0.8%/50 microl), and IGFBP-3 serum levels at baseline (1.7 +/- 0.3 vs 0.86 +/- 0.2 mg/liter) and at 24 hr (2.04 +/- 0.38 vs 0.99 +/- 0.3 mg/liter) did not add to the predictive value of stimulated IGF-I levels at 24 hr and were less accurate in predicting the outcome in comparison to CP score (80%). We conclude that stimulated IGF-1 <10 nmol/liter may be a true predictor of a negative prognosis in patients with liver cirrhosis.
