Alcoholic liver disease in the elderly

Although per capita alcohol consumption, and thus the prevalence of alcoholic liver disease, decreases generally with age in Europe and in the United States, recently an increase in alcohol consumption has been reported in individuals over 65 years. Reasons explaining this observation may include an increase in life expectancy or a loss of life partners and, thus, loneliness and depression. Although ethanol metabolism and ethanol distribution change with age, and an elderly person's liver is more susceptible to the toxic effect of ethanol, the spectrum of alcoholic liver diseases and their symptoms and signs is similar to that seen in patients of all ages. However, prognosis of alcoholic liver disease in the elderly is poor. In addition, chronic alcohol consumption may enhance drug associated liver disease and may also act as a cofactor in other liver diseases, such as viral hepatitis and nonalcoholic fatty liver disease.

Evaluation of the transforming growth factor beta1 codon 25 (Arg-->Pro) polymorphism in alcoholic liver disease

INTRODUCTION: Liver cirrhosis develops only in a minority of heavy drinkers. Genetic factors may account for some variation in the progression of fibrosis in alcoholic liver disease (ALD). Transforming growth factor beta 1 (TGFbeta1) is a key profibrogenic cytokine in fibrosis and its gene contains several polymorphic sites. A single nucleotide polymorphism at codon 25 has been suggested to affect fibrosis progression in patients with chronic hepatitis C virus infection, fatty liver disease, and hereditary hemochromatosis. Its contribution to the progression of ALD has not been investigated sufficiently so far. PATIENTS AND METHODS: One-hundred-and-fifty-one heavy drinkers without apparent ALD, 149 individuals with alcoholic cirrhosis, and 220 alcoholic cirrhotics who underwent liver transplantation (LTX) were genotyped for TGFbeta1 codon 25 variants. RESULTS: Univariate analysis suggested that genotypes Arg/Pro or Pro/Pro are associated with decompensated liver cirrhosis requiring LTX. However, after adjusting for patients' age these genotypes did not confer a significant risk for cirrhosis requiring LTX. CONCLUSION: TGFbeta1 codon 25 genotypes Arg/Pro or Pro/Pro are not associated with alcoholic liver cirrhosis. Our study emphasizes the need for adequate statistical methods and accurate study design when evaluating the contribution of genetic variants to the course of chronic liver diseases.

Estrogen withdrawal and liver fat accumulation : contribution of hepatic VLDL-TG production and effect of exercise training

L’accumulation de triglycérides (TG) dans les hépatocytes est caractéristique de la stéatose hépatique non-alcoolique (SHNA). Cette dernière se produit dans diverses conditions dont le facteur commun est le métabolisme anormal des lipides. Le processus conduisant à l'accumulation des lipides dans le foie n’a pas encore été totalement élucidé. Toutefois, des lipides s'accumulent dans le foie lorsque les mécanismes qui favorisent leur exportation (oxydation et sécrétion) sont insuffisants par rapport aux mécanismes qui favorisent leur importation ou leur biosynthèse. De nos jours il est admis que la carence en œstrogènes est associée au développement de la stéatose hépatique. Bien que les résultats des études récentes révèlent l'implication des hormones ovariennes dans l'accumulation de lipides dans le foie, les mécanismes qui sous-tendent ce phénomène doivent encore être étudiés. En conséquence, les trois études présentées dans cette thèse ont été menées sur des rates ovariectomizées (Ovx), comme modèle animal de femmes post-ménopausées, pour étudier les effets du retrait des œstrogènes sur le métabolisme des lipides dans le foie, en considérant l'entraînement physique comme étant un élément positif pouvant contrecarrer ces effets. Il a été démontré que l'entraînement physique peut réduire l'accumulation de graisses dans le foie chez les rates Ovx. Dans la première étude, nous avons montré que chez les rates Ovx nourries à la diète riche en lipides (HF), les contenus de TG hépatiques étaient élevées (P < 0.01) comparativement aux rates Sham, 5 semaines après la chirurgie. Le changement de la diète HF par la diète standard (SD) chez les rates Sham a diminué l’accumulation de lipides dans le foie. Toutefois, chez les rates Ovx, 8 semaines après le changement de la HF par la SD le niveau de TG dans le foie était maintenu aussi élevé que chez les rates nourries continuellement avec la diète HF. Lorsque les TG hépatiques mesurés à la 13e semaine ont été comparés aux valeurs correspondant au retrait initial de la diète HF effectué à la 5e semaine, les niveaux de TG hépatiques chez les animaux Ovx ont été maintenus, indépendamment du changement du régime alimentaire; tandis que chez les rats Sham le passage à la SD a réduit (P < 0.05) les TG dans le foie. Les mêmes comparaisons avec la concentration des TG plasmatiques ont révélé une relation inverse. Ces résultats suggèrent que la résorption des lipides au foie est contrée par l'absence des œstrogènes. Dans cette continuité, nous avons utilisé une approche physiologique dans notre seconde étude pour investiguer la façon dont la carence en œstrogènes entraîne l’accumulation de graisses dans le foie, en nous focalisant sur la voie de l'exportation des lipides du foie. Les résultats de cette étude ont révélé que le retrait des œstrogènes a entraîné une augmentation (P < 0.01) de l’accumulation de lipides dans le foie en concomitance avec la baisse (P < 0.01) de production de VLDL-TG et une réduction l'ARNm et de la teneur en protéines microsomales de transfert des triglycérides (MTP). Tous ces effets ont été corrigés par la supplémentation en œstrogènes chez les rates Ovx. En outre, l'entraînement physique chez les rates Ovx a entraîné une réduction (P < 0.01) de l’accumulation de lipides dans le foie ainsi qu’une diminution (P < 0.01) de production de VLDL-TG accompagnée de celle de l'expression des gènes MTP et DGAT-2 (diacylglycérol acyltransférase-2). Des études récentes suggèrent que le peptide natriurétique auriculaire (ANP) devrait être au centre des intérêts des recherches sur les métabolismes énergétiques et lipidiques. Le ANP est relâché dans le plasma par les cellules cardiaques lorsque stimulée par l’oxytocine et exerce ses fonctions en se liant à son récepteur, le guanylyl cyclase-A (GC-A). En conséquence, dans la troisième étude, nous avons étudié les effets du blocage du système ocytocine-peptide natriurétique auriculaire (OT-ANP) en utilisant un antagoniste de l’ocytocine (OTA), sur l'expression des gènes guanylyl cyclase-A et certains marqueurs de l’inflammation dans le foie de rates Ovx. Nous avons observé une diminution (P < 0.05) de l’ARNm de la GC-A chez les rates Ovx et Sham sédentaires traitées avec l’OTA, tandis qu’une augmentation (P < 0.05) de l'expression de l’ARNm de la protéine C-réactive (CRP) hépatique a été notée chez ces animaux. L’exercice physique n'a apporté aucun changement sur l'expression hépatique de ces gènes que ce soit chez les rates Ovx ou Sham traitées avec l’OTA. En résumé, pour expliquer l’observation selon laquelle l’accumulation et la résorption de lipides dans le foie dépendent des mécanismes associés à des niveaux d’œstrogènes, nos résultats suggèrent que la diminution de production de VLDL-TG induite par une déficience en œstrogènes, pourrait être un des mecanismes responsables de l’accumulation de lipides dans le foie. L’exercice physique quant à lui diminue l'infiltration de lipides dans le foie ainsi que la production de VLDL-TG indépendamment des niveaux d'œstrogènes. En outre, l'expression des récepteurs de l’ANP a diminué par l'OTA chez les rates Ovx et Sham suggérant une action indirecte de l’ocytocine (OT) au niveau du foie indépendamment de la présence ou non des estrogènes. L’axe ocytocine-peptide natriurétique auriculaire, dans des conditions physiologiques normales, protègerait le foie contre l'inflammation à travers la modulation de l’expression de la GC-A.

Changes of glycogen content in liver, skeletal muscle, and heart from fasted rats

Glycogen content of white and red skeletal muscles, cardiac muscle, and liver was investigated in conditions where changes in plasma levels of non-esterified fatty acids (NEFA) occur. The experiments were performed in fed and 12 and 48 h-fasted rats. The animals were also submitted to swimming for 10 and 30 min. Glycogen content was also investigated in both pharmacologically induced low plasma NEFA levels fasted rats and pharmacologically induced high plasma NEFA levels fed rats. The participation of Akt and glycogen synthase kinase-3 (GSK-3) in the changes observed was investigated. Plasma levels of NEFA, glucose, and insulin were determined in all conditions. Fasting increased plasma NEFA levels and reduced glycogen content in the liver and skeletal muscles. However, an increase of glycogen content was observed in the heart under this condition. Akt and GSK-3 phosphorylation was reduced during fasting in the liver and skeletal muscles but it remained unchanged in the heart. Our results suggest that in conditions of increased plasma NEFA levels, changes in insulin-stimulated phosphorylation of Akt and GSK-3 and glycogen content vary differently in liver, skeletal muscles, and heart. Akt and GSK-3 phosphorylation and glycogen content are decreased in liver and skeletal Muscles, but in the heart it remain unchanged (Akt and GSK-3 phosphorylation) or increased (glycogen content) due to consistent increase of plasma NEFA levels.

Cardiorespiratory fitness, but not central obesity or C-reactive protein, is related to liver function in obese children

Nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity. Its pathogenesis is complex and there are multiple factors that may contribute to it. AIM: To analyze whether cardiorespiratory ftness (CRF), waist circumference (WC), and C-reactive protein (CRP) are associated with alanine aminotransferase (ALT) in children with obesity. METHODS: 79 overweight/obese children of both genders, 11-13 year-olds, with abnormal serum ALT from Porto public schools comprised the sample. Measurements included CRF (20-m Shuttle Run Test), WC (NHANES protocol), CRP and ALT (Cholestech LDX analyzer). Logistic regression adjusted for gender, maturation, and weight with ALT levels as dependent variable (risk vs. non risk), and WC (risk vs. non risk), CRP (risk vs. non risk), and CRF (fit vs. unfit) as independent variables. Level of significance was set at 95%. RESULTS: Logistic regression showed that obese fit children were less likely to have abnormal ALT values (OR=.031) CONCLUSION: In obese children, higher cardiovascular fitness appears to reduce the chance of decreased liver function. © 2013 Human Kinetics, Inc.

Rumen-protected choline supplementation in periparturient dairy goats: effects on liver and mammary gland

The current study investigated the effects of supplementing rumen-protected choline (RPC) on metabolic profile, selected liver constituents and transcript levels of selected enzymes, transcription factors and nuclear receptors involved in mammary lipid metabolism in dairy goats. Eight healthy lactating goats were studied: four received no choline supplementation (CTR group) and four received 4g RPC chloride/day (RPC group). The treatment was administered individually starting 4 weeks before expected kidding and continuing for 4 weeks after parturition. In the first month of lactation, milk yield and composition were measured weekly. On days 7, 14, 21 and 27 of lactation, blood samples were collected and analysed for glucose, beta-hydroxybutyrate, non-esterified fatty acids and cholesterol. On day 28 of lactation, samples of liver and mammary gland tissue were obtained. Liver tissue was analysed for total lipid and DNA content; mammary tissue was analysed for transcripts of lipoprotein lipase (LPL), fatty acid synthase (FAS), sterol regulatory binding proteins 1 and 2, peroxisome proliferator-activated receptor gamma and liver X receptor alpha. Milk yield was very similar in the two groups, but R PC goats had lower (P < 0.05) plasma beta-hydroxybutyrate. The total lipid content of liver was unaffected (P = 0.890), but the total lipid/DNA ratio was lower (both P < 0.05) in RPC than CTR animals. Choline had no effect on the expression of the mammary gland transcripts involved in lipid metabolism. The current plasma and liver data indicate that choline has a positive effect on liver lipid metabolism, whereas it appears to have little effect on transcript levels in mammary gland of various proteins involved in lipid metabolism. Nevertheless, the current results were obtained from a limited number of animals, and choline requirement and function in lactating dairy ruminants deserve further investigation.

Coordinated gene expression in adipose tissue and liver differs between cows with high or low NEFA concentrations in early lactation

Dairy cows with high and low plasma non-esterified fatty acid (NEFA) concentrations in early lactation were compared for plasma parameters and mRNA expression of genes in liver and subcutaneous adipose tissue. The study involved 16 multiparous dairy cows with a plasma NEFA concentration of >500 mumol/l [n = 8, high NEFA (HNEFA)] and <140 mumol/l [n = 8, low NEFA (LNEFA)] in the first week post-partum (pp). Blood samples, adipose and liver tissues were collected on day 1 (+1d) and at week 3 pp (+3wk). Blood plasma was assayed for concentrations of metabolites and hormones. Subcutaneous adipose and liver tissues were analysed for mRNA abundance by real-time qRT-PCR encoding parameters related to lipid metabolism. Results showed that mean daily milk yield and milk fat quantity were higher in HNEFA than in LNEFA cows (p < 0.01), and the NEB was more negative in HNEFA than in LNEFA in +3wk too (p < 0.05). HNEFA cows had slightly lower (p < 0.1) insulin concentrations than LNEFA cows across the study period, and the body condition score decreased more from +1d to +3wk in HNEFA than in LNEFA (p = 0.09). The mRNA abundance of genes in the liver related to fatty acid oxidation (carnitine palmitoyltransferase 2 and very long chain acyl-coenzyme A dehydrogenase) and ketogenesis (3-hydroxy-3-methylglutaryl-coenzyme A synthase 2) were lower in HNEFA than in LNEFA cows. No differences between the two groups were observed for mRNA expression of genes in adipose tissue. The number of calculated significant correlation coefficients (moderately strong) between parameters in the liver and in adipose tissue was nearly similar on +1d, and higher for HNEFA compared with LNEFA cows in +3wk. In conclusion, dairy cows with high compared with low plasma NEFA concentrations in early lactation show differentially synchronized mRNA expression of genes in adipose tissue and liver in +3wk that suggests a different orchestrated homeorhetic regulation of lipid metabolism.

[Psychiatric assessment of alcoholic patients on a waiting list for liver transplantation : Which prognostic criteria are empirically proven?]

Liver disorders are the most frequent somatic complications of alcoholism. As 10‑20% of alcoholic patients will develop liver cirrhosis, this is the most frequent reason for premature death in alcoholic patients. Liver transplantation is now an accepted therapy for alcoholic liver cirrhosis but psychiatric assessment is usually required for patients entering a waiting list for transplantation. Prognostic criteria are controversially discussed, especially the so-called 6-month rule. Numerous studies and recent meta-analyses have indicated that duration of alcoholism, family history, age, sex, comorbid substance use and psychiatric disorders, noncompliance and social instability are outcome predictors. The 6-month criterion is not well proven but some studies are indicative. Possible therapeutic interventions for alcoholic patients on a waiting list are discussed.

Intrarenal resistance index for the assessment of early renal function impairment in patients with liver cirrhosis

BACKGROUND: Renovascular vasoconstriction in patients with hepatorenal syndrome can be quantified by the renal arterial resistance index (RI). We investigated the value of RI measurement in detection of renal function impairment in patients with different stages of chronic liver disease. METHODS: Subjects were divided into 4 groups containing 21 patients with liver cirrhosis and ascites, 25 patients with liver cirrhosis without ascites, 35 patients with fatty liver disease and 78 control subjects. All patients underwent abdominal ultrasound examination with renal RI measurement and correlation with laboratory results for renal function. RESULTS: RI was significantly higher in ascitic patients compared to non-ascitic patients (0.74 vs. 0.67, p<0.01) and in non-ascitic patients with liver cirrhosis than in control subjects (0.67 vs. 0.62, p<0.01). 48% (19/40) of patients with liver cirrhosis and normal serum creatinine concentration showed elevated RI levels. There were no significant differences in RI levels between patients with fatty liver disease and controls (0.63 vs. 0.62). CONCLUSIONS: Intrarenal RI measurement is a predictor of renal vasoconstriction and serves to detect early renal function impairment in cirrhotic patients. The diagnosis of elevated RI may be taken into account in the clinical management of these patients.

PGC-1 alfa como regulador inflamatório na esteato-hepatite não-alcoólica

A doença hepática gordurosa não-alcoólica (NAFLD, do inglês) é a manifestação clínica hepática da síndrome metabólica, cuja incidência aumenta consideravelmente em todo o mundo. A NAFLD pode progredir para um estado de esteatohepatite não-alcoólica (NASH, do inglês), caracterizado por inflamação hepatocelular, com ou sem fibrose. Dados na literatura mostram que o coativador-1 alfa do receptor ativado por proliferadores de peroxissoma gama (PGC-1alfa), além de estar envolvido em diversos processos metabólicos, representa uma estratégia terapêutica promissora na modulação da inflamação. Neste projeto investigamos as alterações inflamatórias no fígado induzida por dieta hiperlipídica e o papel do PGC-1alfa nesse processo. Camundongos C57black/6 receberam dieta hiperlipídica contendo 30% de gordura por 10 semanas. O peso dos animais foi avaliado semanalmente. Após a eutanásia, o tecido adiposo intra-abdominal (retroperitoneal e periepididimal) foi coletado e pesado. Analisamos o perfil glicêmico e lipídico sérico e expressão de genes envolvidos no metabolismo glicêmico e lipídico. Avaliou-se também o aspecto histológico e a inflamação do tecido hepático por quantificação das citocinas IL-6, TNF-alfa e IL-1beta. A dieta rica em gordura conduziu a um aumento dos depósitos de gordura intra-abdominal, hiperglicemia e hiperlipidemia. Os animais também apresentavam esteatohepatite, com aumento de citocinas pró-inflamatórias e diminuição na expressão de PGC-1alfa no tecido hepático. O envolvimento do PGC-1alfa na produção de mediadores inflamatórios por hepatócitos foi avaliado em células HepG2 utilizando RNA de interferência (RNAi). O knockdown da expressão de PGC-1alfa causou aumento na expressão e liberação de IL-6 em hepatócitos via aumento na fosforilação de IkBalfa e consequente ativação do NFkB. Portanto, nossos dados mostram que o PGC-1alfa inibe a produção de mediadores inflamatórios (IL-6) em hepatócitos, e fornecem novas evidências das conexões existentes entre as vias metabólicas e imunes

Reduced hepatic extraction of palmitate in steatosis correlated to lower level of liver fatty acid binding protein

Nonalcoholic fatty liver disease is the most common of all liver diseases. The hepatic disposition [H-3]palmitate and its low-molecular-weight metabolites in perfused normal and steatotic rat liver were studied using the multiple indicator dilution technique and a physiologically based slow diffusion/bound pharmacokinetic model. The steatotic rat model was established by administration of 17alpha-ethynylestradiol to female Wistar rats. Serum biochemistry markers and histology of treated and normal animals were assessed and indicated the presence of steatosis in the treatment group. The steatotic group showed a significantly higher alanine aminotransferase-to-aspartate aminotransferase ratio, lower levels of liver fatty acid binding protein and cytochrome P-450, as well as microvesicular steatosis with an enlargement of sinusoidal space. Hepatic extraction for unchanged [H-3]palmitate and production of low-molecular-weight metabolites were found to be significantly decreased in steatotic animals. Pharmacokinetic analysis suggested that the reduced extraction and sequestration for palmitate and its metabolites was mainly attributed to a reduction in liver fatty acid binding protein in steatosis.

Neurobiological alterations in the human alcoholic brain: effect of genotype

Long-term alcohol abuse by human subjects leads to selective brain damage that is restricted in extent and variable in severity. Within the cerebral cortex, neuronal loss is most marked in the superior frontal cortex and relatively mild in motor cortex. Cirrhotic alcoholics and subjects with alcohol-related Wernicke-Korsakoff syndrome show more severe and more extensive damage than do uncomplicated cases. Accumulating evidence suggests that the likelihood of developing alcohol dependency is associated with one or more genetic markers. In previous work we showed that GABAA receptor functionality, and the subunit isoform expression that underlies this, differed in region- and disease-specific ways between alcoholics and controls. By contrast, glutamate receptor (NMDA, KA, AMPA) differences were muted or absent. Here we asked if genotype differentiated the form, pharmacology, or expression of glutamate and GABA receptors in pathologically vulnerable and spared cortical regions, with a view to determining whether such subject factors might influence the severity of alcohol-induced brain damage. Cerebrocortical tissue was obtained at autopsy under informed, written consent from uncomplicated and alcoholic-cirrhotic Caucasian (predominantly Anglo-Celtic) cases, together with matched controls and cases with cirrhosis of non-alcoholic origin. All subjects had pathological confirmation of liver and brain diagnosis; none had been polydrug abusers. Samples were processed for synaptic membrane receptor binding, mRNA analysis by quantitative RT-PCR, and protein analysis by Western blot. Genotyping was performed by PCR methods, in the main using published primers. Several genetic markers differentiated between our alcoholic and control subjects, including the GABAA receptor 2 subunit (GABB2) gene ( 2 (3) 10.329, P 0.01), the dopamine D2 receptor B1 (DRD2B) allele ( 2 (3) 10.109, P 0.01) and a subset of the alcohol dehydrogenase-3 (ADH3) alleles ( 2 (2) 4.730, P 0.05). Although neither the type-2 glutamate transporter (EAAT2) nor the serotonin transporter (5HTT) genes were significantly associated with alcoholism, only EAAT2 heterozygotes showed a significant association between ADH3 genotype and alcoholism ( 2 (3) 7.475, P 0.05). Other interactions between genotypes were also observed. DRD2A, DRD2B, GABB2, EAAT2 and 5HTT genotypes did not divide alcoholic cases and controls on NMDA receptor parameters, although in combined subjects there was a significant DRD2B X Area Interaction with glutamateNMDA receptor efficacy (F(1,57) 4.67; P 0.05), measured as the extent of glutamate-enhanced MK801 binding. In contrast, there was a significant Case-group X ADH3 X Area Interaction with glutamateNMDA receptor efficacy (F(3,57) 2.97; P 0.05). When GABAA receptor subunit isoform expression was examined, significant Case-group X Genotype X Area X Isoform interactions were found for EAAT2 with subunit mRNA (F(1,37) 4.22; P0.05), for GABB2 with isoform protein (F(1,37) 5.69; P 0.05), and for DRD2B with isoform protein (F(2,34)5.69; P0.05). The results suggest that subjects’ genetic makeup may modulate the effectiveness of amino acid-mediated transmission in different cortical regions, and thereby influence neuronal vulnerability to excitotoxicity.

Intrahepatic cholestasis of pregnancy : genetic background, epidemiology and hepatobiliary consequences

Intrahepatic cholestasis of pregnancy (ICP) is the most common cholestatic liver disease during pregnancy. The reported incidence varies from 0.4 to 15% of full-term pregnancies. The etiology is heterogeneous but familial clustering is known to occur. Here we have studied the genetic background, epidemiology, and long-term hepatobiliary consequences of ICP. In a register-based nation-wide study (n=1 080 310) the incidence of ICP was 0.94% during 1987-2004. A slightly higher incidence, 1.3%, was found in a hospital-based series (n=5304) among women attending the University Hospital of Helsinki in 1992-1993. Of these 16% (11/69) were familial and showed a higher (92%) recurrence rate than the sporadic (40%) cases. In the register-based epidemiological study, advanced maternal age and, to a lesser degree, parity were identified as new risk factors for ICP. The risk was 3-fold higher in women >39 years of age compared to women <30 years. Multiple pregnancy also associated with an elevated risk. In a genetic study we found no association of ICP with the genes regulating bile salt transport (ABCB4, ABCB11 and ATP8B1). The livers of postmenopausal women with a history of ICP tolerated well the short-term exposure to oral and transdermal estradiol, although the doses used were higher than those in routine clinical use. The response of serum levels of sex hormone-binding globulin (SHBG) to oral estradiol was slightly reduced in the ICP group. Transdermal estradiol had no effect on C-reactive protein (CRP) or SHBG. A number of liver and biliary diseases were found to be associated with ICP. Women with a history of ICP showed elevated risks for non-alcoholic liver cirrhosis (8.2 CI 1.9-36), cholelithiasis and cholecystitis (3.7 CI 3.2-4.2), hepatitis C (3.5 CI 1.6-7.6) and non-alcoholic pancreatitis (3.2 CI 1.7-5.7). In conclusion, ICP complicates around 1% of all full-term pregnancies in Finland and its incidence has remained unchanged since 1987. It is familial in 16% of cases with a higher recurrence rate. Although the cause remains unknown, several risk factors, namely advanced maternal age, parity and multiple pregnancies, can be identified. Both oral and transdermal regimens of postmenopausal hormone therapy (HT) are safe for women with a history of ICP when liver function is considered. Some ICP patients are at risk of other liver and biliary diseases and, contrary to what has been thought, a follow-up is warranted.
