Abstract
Selenoprotein P is a hepatokine with antioxidative properties that eliminate a physiologic burst of reactive oxygen species required for intracellular signal transduction. Serum levels of selenoprotein P are elevated during aging and in people with type 2 diabetes, non-alcoholic fatty liver disease, and hepatitis C. However, how serum levels of full-length selenoprotein P are regulated largely remains unknown, especially in the general population. To understand the significance of serum selenoprotein P levels in the general population, we evaluated intrinsic and environmental factors associated with serum levels of full-length selenoprotein P in 1,183 subjects participating in the Shika-health checkup cohort. Serum levels of selenium were positively correlated with liver enzymes and alcohol intake and negatively correlated with body mass index. Serum levels of selenoprotein P were positively correlated with age, liver enzymes, and alcohol intake. In multiple regression analyses, alcohol intake was positively correlated with serum levels of both selenium and selenoprotein P independently of age, gender, liver enzymes, and fatty liver on ultrasonography. In conclusion, alcohol intake is associated with elevated serum levels of selenium and selenoprotein P independently of liver enzyme levels and liver fat in the general population. Moderate alcohol intake may exert beneficial or harmful effects on health, at least partly by upregulating selenoprotein P. These findings increase our understanding of alcohol-mediated redox regulation and form the basis for the adoption of appropriate drinking guidelines.

Abstract
Macronutrients and trace elements are important components of living tissues that have different metabolic properties and functions. Trace elements participate in the regulation of immunity through humoral and cellular mechanisms, nerve conduction, muscle spasms, membrane potential regulation as well as mitochondrial activity and enzymatic reactions. Excessive alcohol consumption disrupts the concentrations of crucial trace elements, also increasing the risk of enhanced oxidative stress and alcohol-related liver diseases. In this review, we present the status of selected macroelements and trace elements in the serum and plasma of people chronically consuming alcohol. Such knowledge helps to understand the mechanisms of chronic alcohol-use disorder and to progress and prevent withdrawal effects, also improving treatment strategies.

Abstract
In alcoholic hepatitis, Kupffer cells are activated by intestinal gram-bacteria, leading to cytokine production and free radicals release, which, enhancing cytokine secretion, create a positive feedback loop which contributes to liver inflammation. Free radicals also damage the liver in chronic hepatitis C virus (HCV) infection, a condition frequently associated to alcohol consumption. In both situations, activity of antioxidant enzymes and of its cofactors zinc (Zn), selenium (Se), and copper (Cu) is important. This study was performed to assess the relative and combined effects of chronic alcoholism and HCV infection on serum Se, Zn, and Cu, and its relation with serum malondialdehyde (MDA) and tumor necrosis factor-α, interferon-γ, and interleukins (IL) 4, 6, and 8, in 19 HCV- alcoholic patients, 12 HCV+ alcoholic patients, nine HCV+ non-alcoholic patients, and 20 controls. Serum Zn and Se were lower in both HCV+ and HCV- alcoholic patients, whereas serum Cu was lower in HCV+ individuals. Serum Zn and Se were related to liver function derangement. MDA levels were higher in alcoholics, but no relation was observed between trace elements and MDA or cytokines, so that our results do not support a relevant role of the analyzed trace elements in the pathogenesis of chronic liver disease.

Abstract
In alcoholics, exposure of Kupffer cells to intestinal-borne Gram-negative bacteria increases free radical release, which may, in turn, enhance cytokine secretion, creating a positive feedback loop, which contributes to liver inflammation. Impaired antioxidant mechanisms further aggravates this scenario. Some trace elements, such as selenium, are main cofactors of antioxidant enzymes. Some authors have found low Se levels in alcoholics in relation either with undernutrition, liver dysfunction, or intensity of alcoholism, but in general, Se supplementation has no effect on survival. In this study we measured serum Se in 16 controls and 76 alcoholics, 34 of them cirrhotics, 68 of whom were followed up for a median period of 38 months; 17 died during this period. Se levels were lower in patients than in controls and were related to prothrombin activity and nutritional status, more closely to this last parameter (stepwise logistic regression analysis). Patients who died showed lower Se values than those who survived. Se values over the median were associated with better survival, assessed by Kaplan-Meier curves and log-rank test. However, in multivariate analysis (Cox regression model), prothrombin activity displaced serum Se as a prognostic factor. We conclude that serum Se levels are low in alcoholics; these low values depend more heavily on impaired nutrition but also on liver dysfunction; although low Se levels were associated with a higher mortality, prothrombin activity displaced serum Se when survival was assessed using Cox's regression model.

Abstract
Chronic heavy alcohol consumption adversely affects both macronutrients and micronutrients. Alcohol use affects selenium status. Considerable evidence suggests that selenium status may modify mental function. The author suggests that the effects of alcohol intake on mood, behavior, and cognition may be partly mediated by biological changes related to selenium deficiency. It has been observed that there is a trend towards the normalization of selenium levels in patients with alcoholism after a relatively short period of abstinence from alcohol. It has also been observed that when depression develops in persons with alcoholism, they are likely to improve fairly rapidly after a relatively short period of abstinence from alcohol without therapy aimed at the depressive symptoms. The author suggests that improvement in depressed patients after a period of abstinence from alcohol might be in part related to the normalization of selenium status. Treatment and prevention of comorbid alcoholism and mood disorders require more attention by research workers, practicing physicians, and the general public. Future studies of the etiology and pathogenesis of mood disorders in patients with alcoholism are merited.

Abstract
Thyroid hormones play a role in the regulation of glutathione S-transferase (GST) expression. Here, co-cultures of rat hepatocytes with bile duct epithelial cells have been used to study the direct effects of both triiodothyronine (T3) and thyroxine (T4) on GST activities and proteins. Because T3 and T4 are poorly water soluble and organic solvents used to dissolve them often interfere with biotransformation pathways, an alternative delivery system namely hydroxypropyl-beta-cyclodextrin (HPBC) has been applied. Appropriate control cultures contained either 0.02 or 0.10% (w/v) HPBC, the concentrations necessary to supply T3 and T4 (10(-9) to 10(-5) M) to the cells, respectively. No effect of the vehicle HPBC on the different GST isoenzyme activities and proteins could be observed. On the contrary, after 10 days of co-culture, T3 and T4 decreased GST protein concentrations as well as GST activities measured by 1-chloro-2,4-dinitrobenzene (broad spectrum), 1,2-dichloro-4-nitrobenzene (Mu class M1/M2-specific) and 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole (Alpha class A1/2-specific) in a concentration-dependent manner. The Alpha class subunits A1/2 and A3, and the Mu class subunit M2 were mostly affected. No effect was observed on the Pi class enzyme. These findings indicate that a combination of co-cultured hepatocytes with an HPBC-based delivery system for hydrophobic compounds represents a powerful in vitro tool in drug development.

Abstract
The concentration of serum selenium in 395 individuals (187 males + 218 females) living in the Canary Islands, Spain was determined by hydride generation atomic absorption spectrometry. The mean selenium concentration was 74.7 +/- 25.2 microg/l ranging between 7.86 and 182.3 microg/l. Twenty-two adults (7.2% of the total) had serum selenium concentrations under 45 microg/l. It is widely accepted that below this selenium serum concentration (45 microg/l) there is an increased risk of cardiovascular disease and cancer. Our results fall within data recently published in other Spanish and European regions and are much lower than data observed in USA or seleniferous regions. The estimated Se intakes of our population were lower than the Recommended Dietary Allowances for American people. Individuals from Lanzarote had a mean Se concentration significantly higher than individuals from the other islands. This could be attributed to differences in Se content of soil and/or differences in dietary habits of the populations. Serum selenium concentration did not vary with the sex of the subjects. Individuals younger than 14 years old had a serum selenium concentration significantly lower than the rest of the individuals. No relationship with socio-economic status, educational level, smoking habits, physical exercise or beer consumption was found. However, individuals who consume wine more than three times a week showed higher selenium concentrations than individuals with lower consumption. Also, individuals with consumption above seven units of spirit drinks a week had the highest mean selenium concentration.

Abstract
Tau immunoreactivity was examined in post mortem tissue from patients in three groups: neurologically-asymptomatic and neuropathologically normal alcoholics, alcoholics with Wernicke's Encephalopathy (WE) and age matched non-alcoholic controls. Tau-positive granular and fibrillary inclusions were frequently observed within the magnocellular neurons of the cholinergic nucleus basalis, within occasional nucleus basalis neurons in non-WE alcoholics, but not in controls. Tau immunoreactivity was not however observed in cortical, brainstem, diencephalic or non-cholinergic forebrain structures. Peroxidase activity was also examined within the nucleus basalis using diaminobenzidine as an indicator. The majority of neurons in the basal forebrain showed increased peroxidase activity in all WE alcoholics and in some nucleus basalis neurons of non-WE alcoholics, but was rarely seen in controls. Neighboring astrocytes also showed increased peroxidase activity. These results suggest a link between peroxidase activity and the abnormal accumulation of phosphorylated tau. The presence of tau in the nucleus basalis of alcoholics with WE suggests a thiamine-dependent mechanism in tau accumulation and cell death in the cholinergic basal forebrain.

Abstract
Effects of chronic ingestion of 2 levels of alcohol on selenium (Se) utilization were determined in initially Se-depleted rats. Male weanling rats were fed ad lib a Se deficient (0.012 mg/kg) basal diet for 4 weeks and then were meal-fed low or marginally adequate Se in the form of high Se yeast for 4 weeks. During Se repletion, ethanol, which replaced medium-chain triglycerides in the diet, provided 10 or 20 percent of food energy. The basal diet provided 80% of food energy as well as adequate protein, vitamins and minerals. In rats given adequate Se moderate chronic ethanol consumption did not influence Se absorption or retention, but increasing ethanol level raised Se in liver and whole blood in a linear fashion and in kidney in a quadratic manner. In this rat model measures of Se status were reduced by low Se intake, not chronic moderate ethanol ingestion.

Abstract
To study the mechanism of the reduced serum selenium concentration in patients with liver damage we administered 200 micrograms (2.53 mumol) selenium daily as selenium-rich yeast to 8 patients with primary biliary cirrhosis and 8 healthy controls over 16 weeks. Initially selenium concentrations in serum were 24% lower (P less than 0.001) in patients than controls. During supplementation serum selenium levels increased in both groups but the difference between them persisted. Throughout the study whole blood selenium levels and glutathione peroxidase activities were also somewhat lower (P = NS) in patients than controls. Selenium supplementation had no effect on whole blood glutathione peroxidase activities in either group. The basal 24 h urinary excretion of selenium was similar in both groups but was increased more by supplementation in patients than controls. Selenium administration did not influence the liver function of the patients. We conclude that impaired hepatic production of selenium-containing serum compounds is the most likely explanation for the reduced serum selenium concentration in patients with primary biliary cirrhosis.

Abstract
Relationships between blood levels of selenium (SE) and SE-dependent glutathione peroxidase (GPX) activity and selected lifestyle variables including ethanol ingestion, smoking behavior, nutrient intake, and nutrient supplement use were studied in 124 male and female subjects, half of whom drank alcoholic beverages lightly or moderately. Among the 19 independent lifestyle variables included in correlation and multiple regression analysis, ethanol intake was most strongly and consistently associated with levels of plasma and whole blood SE and plasma GPX activity, r = .32-.34, p less than 0.01. Light to moderate drinkers had higher, p less than 0.05, whole blood and plasma SE and GPX than subjects abstaining from alcohol. SE intake was not different. This positive association was in contrast to some previous reports in which alcoholics were shown to have lower blood SE levels than control subjects. A possible explanation could be the adequate SE intake and the light to moderate ethanol consumption of drinkers in this study.

Abstract
Glutathione peroxidase activity and selenium and vitamin E levels were measured in the plasma and erythrocytes of 25 chronic alcoholic patients without liver cirrhosis before and after 14 days of abstinence from alcohol, and compared with the levels in 25 sex- and age-matched healthy controls. Before abstinence, all three levels were shown significantly depressed in the alcoholic patients compared with the controls, in both plasma (80, 71, and 89% of control values) and erythrocytes (68, 70, and 83% of control values). After a 14-day abstinence period with no dietary supplementation, a trend towards normalization was noted in erythrocyte (vitamin E and glutathione peroxidase 74 and 91% of control values respectively), in whole blood selenium (82%) and plasma in vitamin E (74%). However, plasma selenium and glutathione peroxidase values were lower than pre-abstinence values (76% and 86% of control values respectively). Our results point to a deficiency in the antioxidant defense system of chronic alcoholics before the occurrence of severe liver disease. This lack of protection against lipoperoxides is all the more important in circumstances like chronic alcohol consumption, in which lipid peroxidation is known to increase. However, the present study also demonstrated that during 14 days of a normal diet free of ethanol, a rapid trend occurred towards the normalization of the factors.

Abstract
The effect of ethanol consumption on serum concentration of alpha-tocopherol, erythrocyte activities of superoxide dismutase, glutathione peroxidase, and catalase were studied in 34 male alcoholics and 35 age-matched controls. Serum concentration of alpha-tocopherol was 30% lower in the alcoholics as compared to the controls (p less than 0.001). No significant difference was found in erythrocyte activities of Cu-Zn-containing superoxide dismutase, glutathione peroxidase, or catalase between the groups. Of the 12 alcoholics with subnormal serum alpha-tocopherol, 50% had concomitant neurological clinical scores and cerebellar atrophy, and their neurological scores were significantly higher (82%) than for alcoholics with normal alpha-tocopherol levels (p less than 0.03). However, no significant correlation was observed between levels of alpha-tocopherol and neurological clinical scores or cerebellar atrophy. When entering the study, alcoholics and controls were each randomized into two separate groups, receiving vitamin E supplementation (100 mg/day) or placebo capsules for 10 days, respectively. In the four subgroups, alpha-tocopherol levels increased only in alcoholics receiving vitamin E supplementation (23%) (p less than 0.001). The reduced serum levels of alpha-tocopherol in alcoholics may be normalized by vitamin E supplementation.

Abstract
Selenium deficiency has been implicated as contributing to hepatic injury in alcoholics. The mechanism by which this occurs is most likely lipoperoxidation secondary to decreased activity of the selenoenzyme glutathione peroxidase. To further assess this relationship, we measured selenium content in autopsy livers in 12 patients with alcoholic cirrhosis compared to 13 patients matched for age and sex dying from other causes, mostly with cardiopulmonary diseases. The mean (+/- SEM) hepatic selenium content in cirrhosis was 0.731 +/- 0.077 microgram/g dry weight versus 1.309 +/- 0.166 microgram/g in controls (P less than 0.005; Student's t test). Clinical and biochemical indices of significant hepatic dysfunction, including encephalopathy, ascites, and elevations of serum bilirubin or prothrombin time, were only present in the cirrhotic group. A significant inverse correlation between hepatic selenium content and the prothrombin time was noted (r = -0.50; P less than 0.02). No significant relationships between hepatic selenium and the abnormalities of bilirubin, albumin, or aspartate aminotransferase were found. We conclude that significantly decreased hepatic selenium stores are present in patients with severe alcoholic cirrhosis compared to controls. The magnitude of that selenium deficit does correlate with some indices of hepatic function, specifically the prothrombin time. These data lend further support to a true selenium deficiency state in alcoholic cirrhosis. It is highly possible that selenium deficiency represents an important link, synergistically joining the nutritional and hepatotoxic backgrounds of alcoholic liver injury and cirrhosis.

Abstract
Severe protein-calorie malnutrition is common in patients with AIDS and could contribute to the progressive deterioration characteristic of that disease. Selenium deficiency could also have a negative impact on immune function and other organ functions vital for recovery from infectious diseases. Therefore, to assess any role for selenium in AIDS we determined plasma and erythrocyte selenium levels and glutathione peroxidase activity in 13 patients with AIDS compared to 8 patients with AIDS-related complex (ARC) and 14 healthy controls. Plasma selenium levels were significantly reduced in AIDS patients compared to controls (p less than .0001) and to ARC (p less than .02). Erythrocyte selenium levels in both AIDS and ARC were also reduced compared to controls (p less than .02), but not to each other. Glutathione peroxidase activity in AIDS was 28.9 +/- 1.4 U/g Hb vs 38.4 +/- 6.9 in ARC (p = NS) and 52.3 +/- 1.7 in controls (p less than .0001 vs AIDS; p less than .02 vs ARC). When all groups were combined, there were significant correlations between total lymphocyte count and both plasma selenium (r = .53; p less than .002) and erythrocyte glutathione peroxidase activity (r = .65; p less than .0001). In addition, strong correlations were noted between plasma selenium and serum albumin (r = .68; p less than .0001), plasma selenium and glutathione peroxidase (r = .77; p less than .0001), and glutathione peroxidase and hematocrit (r = .66; p less than .0001). In AIDS or ARC, no correlations between selenium with disease duration or weight loss were present. We conclude that, in comparison to normals, patients manifesting infection with human immunodeficiency virus have evidence of selenium deficiency as determined by diminished plasma and erythrocyte levels and glutathione peroxidase activity. These abnormalities are most marked in patients with AIDS, but are also present in patients with AIDS-related complex. Selenium deficiency has important implications for the progression and pathogenesis of clinical disease in AIDS.

Abstract
Serum levels of selenium magnesium, copper, zinc and iron were studied in chronic drunkenness arrestees and a healthy control group. The mean serum concentrations of selenium and magnesium were both significantly lower (P less than 0.01) in drunkenness arrestees than in the control subjects. The mean alcohol intake was 190 g of absolute alcohol daily in drunkenness arrestees and 14 g in controls. The erythrocyte glutathione peroxidase concentrations of the study groups did not support poor selenium intake as a principal cause of low selenium concentration in the serum.

Abstract
To study the relation between blood and liver selenium levels in hepatic disorders we measured the selenium concentrations of whole blood, serum and liver tissue obtained at laparoscopy in 17 patients with different kinds of liver diseases. As compared to healthy controls the mean concentration of selenium was decreased by 24% (p less than 0.001) in the whole blood of the patients (n = 15). Similarly, the mean concentration of selenium in serum was 35% lower in the patients than in the controls (p less than 0.001). As compared to the control samples obtained at autopsy the selenium content of liver was decreased by 13% (p less than 0.05) in the patients. Significant positive correlations were found between the selenium content of the liver and the whole blood (r = 0.62, p less than 0.05) as well as also between liver and serum (r = 0.52, p less than 0.05) selenium concentrations. In conclusion, the present study suggests that in patients with liver disorders the selenium concentrations are decreased not only in the blood but also in the liver tissue. Whether this means a decreased activity of hepatic glutathione peroxidase and, further, an increased possibility of oxidative cell injury, remains open.

Abstract
Selenium deficiency has been implicated as contributing to the development of cardiovascular disease, skeletal muscle myopathy, anemia, increased cancer risk, and deranged immune function. Since these problems may also be associated with renal failure, and the kidney plays an important role in selenium homeostasis, we measured selenium and compared it with nutritional status in 24 stable hemodialysis patients, 12 chronic intermittent peritoneal dialysis patients, and 29 healthy controls. Whole blood and plasma selenium was determined by a spectrofluorometric method. For whole blood the mean (+/- SD) selenium levels were 0.11 +/- 0.02 micrograms/ml in controls vs. 0.071 +/- 0.01 micrograms/ml in hemodialysis cases and 0.052 +/- 0.006 micrograms/ml in peritoneal dialysis (p less than 0.005). Significant decreases were seen also for plasma and red blood cell selenium in all groups respectively. Pre- and postdialysis plasma and whole blood selenium levels showed no significant changes in both dialysis groups. However, predialysis residual peritoneal fluid did contain selenium (0.029 +/- 0.005 micrograms/ml). Some evidence of protein-energy undernutrition was noted in both dialysis groups compared with controls. However, no significant differences in nutritional parameters were noted between hemodialysis and peritoneal dialysis patients. When all groups were combined, significant correlations were found between whole blood selenium and serum albumin (r = 0.61; p less than 0.001), triceps skin fold in females (r = 0.62; p less than 0.001), and midarm muscle circumference in males (r = 0.71; p less than 0.001). We conclude that low blood selenium is present in renal failure patients undergoing hemodialysis. This abnormality is even greater in peritoneal dialysis cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Erythrocytes from alcoholics without liver cirrhosis and control subjects were examined for the susceptibility to lipid peroxidation. Erythrocytes of patients were found to be sensitive to H2O2-induced peroxidation as compared to controls. In addition, chronic alcoholics showed a high level of plasma lipid peroxide levels. These results suggest the stimulation of lipid peroxidation in chronic alcoholics.

Abstract
The cancers consistently associated with ingestion of alcohol, the head and neck cancers, are also associated with tobacco use and arise from epithelia that are in direct contact with both agents. Tobacco smoking-related cancers at sites not directly in contact with alcoholic beverages, that is, lung, bladder, and perhaps pancreas, do not consistently show a relationship to alcohol consumption, although lung and pancreatic tumors are associated in some studies. Liver cancer was thought to be strongly related to alcohol consumption on epidemiological grounds and because of its relationship to cirrhosis. As knowledge of the viral etiology of some cirrhoses has evolved and as methods to detect viruses have developed, the significant association between hepatitis B virus and hepatocellular carcinoma has become clear. Alcohol and hepatitis B virus may interact in the etiology of the disease and have important separate roles as well. There are epidemiologic and experimental data showing that malnutrition (resulting from poor food choice), economic deprivation, or alcoholism contributes to the risk for head, neck, and liver cancers. Colon cancers occur about equally in men and women, are found in well-nourished populations, and are not associated with tobacco smoking. Rectal cancers show a preponderance of cases in men but are frequently found in women as well and are not thought to be associated with smoking or malnutrition. The association between colorectal cancers and alcohol consumption, when it is found, apparently occurs at even relatively low alcohol intakes and is often stronger for consumption of beer than of other beverages. Nutritional and metabolic mechanisms proposed for the influence of alcohol on carcinogenesis are supported by studies in human subjects and laboratory animals. Animal models are needed in which effects of ethanol on carcinogenesis can be consistently demonstrated and which can then be used to examine mechanisms.

Abstract
Selenium deficiency has been implicated as a cause of hepatic injury, possibly from accentuated lipoperoxidation due to decreased activity of the selenoenzyme, glutathione peroxidase. Because of possible clinical and biochemical links between selenium and alcohol, we performed nutritional assessment and assayed red blood cell, plasma, and whole blood selenium by spectrofluorometry in 27 normals (group I), 30 asymptomatic alcoholics on admission to a detoxification unit, (group II) and 16 alcoholics with severe liver disease (group III). We found a mean (+/- SD) whole blood selenium of 0.109 micrograms/ml +/- 0.014 for group I vs 0.076 +/- 0.010 for group II (P less than 0.001), and 0.047 +/- 0.006 for group III (P less than 0.001 vs group I and II). For plasma, the mean (+/- SD) selenium was 0.095 micrograms/ml +/- 0.016 for group I versus 0.065 micrograms/ml +/- 0.012 in group II and 0.038 micrograms/ml +/- 0.007 in group III (All P less than 0.001). Calculated red blood selenium levels were also significantly reduced in alcoholics versus controls. Whole blood and plasma selenium correlated directly with serum albumin. For whole blood selenium versus albumin, r = 0.73 (P less than 0.01), and for plasma selenium versus albumin, r = 0.71 (P less than 0.01). A significant inverse correlation was noted between whole blood selenium and the height of the total serum bilirubin (r = -0.46), alkaline phosphatase (r = -0.50), and AST (r = -0.51) (P less than 0.01 for all). Among alcoholics admitted for detoxification, selenium was diminished despite the absence of severe malnutrition, as determined by standard nutrition assessment parameters.(ABSTRACT TRUNCATED AT 250 WORDS)
