The assessment of the nutritional value of meals consumed by patients with recognized schizophrenia

Background: As studies show, changes in diet - so important in the therapy of psychiatric disorders and related to changes in appetite and nutritional preferences, including avoiding of the consumption of specific groups of products and dishes - are much more frequent among patients affected by schizophrenia. Objective: The aim of the study was to assess the chosen nutritional habits, including the number and type of meals usually consumed during a day, snacking between meals and the energy value and content of the chosen nutrients in the diets of persons with recognized schizophrenia. Material and methods: The study was carried out in a group of 85 patients with recognized schizophrenia, and 70 healthy volunteers ranging in age from 18-65 years without mental or nutritional disorders. For the purpose of the study, we used a questionnaire containing questions on nutritional habits. A 24-hour diet recall was used in the quantitative nutritional assessment with the use of the computer program Dieta 5.0. Results: Female patients with recognized schizophrenia were having 3 meals a day significantly more frequently as compared to healthy women. They were also having an afternoon snack much more frequently as compared to the control group. The food rations of female patients were characterized by a significantly higher energy value and the content of most of the assessed nutrients as compared to the food rations of healthy women. The food rations of men with recognized schizophrenia were characterized by a much lower energy intake and the content of the majority of assessed nutrients as compared to the food rations of healthy men. In all compared groups, we observed an energetic structure of food rations with the breakdown by specific meals that was inconsistent with the applicable recommendations. Conclusions: Despite of differences between the nutritional value of the meals of patients with recognized schizophrenia and those of healthy subjects, it seems advisable to involve patients with recognized schizophrenia in the education of forming appropriate nutritional habits.

Immune suppression of IgG response against dairy proteins in major depression.

BACKGROUND: Interactions between the digestive system, brain functions and immunoglobulin G (IgG) mediated immunity against food antigens became recently a topic of growing interest in psychiatry research. Psychological stress can activate hypothalamic-pituitary-adrenal axis (HPA) with subsequent hypercortisolemia. It can also influence intestinal permeability and dynamics of IgG response. Major depression can by accompanied either by activation of inflammatory response or by immune suppression (e.g. decreased antibody production) where hypercortisolemia is a significant immune modulator. The aim of our study was to assess IgG immune response against 44 food products in depressed patients and controls along with markers of psychological stress, inflammation, psychometric and dietary parameters. METHODS: Serum IgG concentrations against 44 food antigens, plasma cortisol, TNF-α, IL-6, IL-1b concentrations were measured and psychometric parameters were evaluated using Hamilton Depression Rating (HAM-D 17), Perceived Stress (PSS-10), and Symptom Checklist (SCL-90) scales in 34 depressed patients and 29 controls. Dietary parameters such as frequency of exposure to food antigens, appetite and weight change were assessed. RESULTS: There was a significantly lower IgG concentration against dairy in depressed patients compared to controls (post hoc p < 0.05) when there was a high exposure (consumption) to dairy. Our research revealed a significant interaction of IgG concentration against dairy proteins and exposure to dairy between groups (F (2.63) = 3.92, p = 0.025, η2 = 0.12). There was no significant difference in mean IgG concentration against food antigens between patients and controls. We found increased concentration of cortisol in depressed patients (t (1.61) = 2.37, p = 0.02) compared to controls. Patients with melancholic depression had significantly higher (M rank  = 21.27) concentration of cortisol (U = 41, p = 0.006), when compared with the non-melancholic group of patients (M rank  = 12.16). Cortisol concentration significantly positively correlated with HAM-D 17 (r = 0.442, p = 0.009) and with phobias in SCL-90 scale in patients' group (r = 0.531, p = 0.001). There was decreased concentration of TNF-α (t = 4.256, p < 0.001) in depressed patients compared to controls. IgG concentration of 38.63% food products positively correlated with TNF-α concentration in depressed patients compared to 9.09% of those in healthy controls. CONCLUSIONS: We observed an immune suppression of IgG response to dairy proteins in depressed patients. Hypercortisolemia with involvement of decreased concentration of TNF-α might play a significant role in suppression of IgG response in depressed patients.

The differences in level of trait anxiety among girls and boys aged 13-17 years with myopia and emmetropia.

BACKGROUND: A significant increase in myopia among children and teenagers can be observed all over the world. Yet at the same time, there is still an insignificant number of studies concerning this health problem. The aim of this study was to assess the level of trait anxiety among myopic group of teenagers in comparison to teenagers with emmetropia, and to confirm whether the level of trait anxiety relates to age and gender. METHODS: Two hundred thirty-nine students aged 13-17 years were included in the study. The study group comprised 114 persons with myopia (81 girls and 33 boys), while the control group comprised 125 persons without refractive error (79 girls and 46 boys). Volunteers completed a set of questionnaires including: personal data, State-Trait Anxiety Inventory for Children (STAIC) (13-14 year-olds), or State-Trait Anxiety Inventory (STAI) (15-17 year-olds). The trait anxiety subscales were thus analyzed. RESULTS: Among younger adolescents (13-14 years of age) with myopia there was a significantly higher incidence of pathological intensification of anxiety as a constant trait. After taking into account the distribution of gender, there was a higher level of trait anxiety in the group of boys with myopia than in the control group aged 13-17 years and 13-14 years. There was also a higher level of trait anxiety detected in males than in females. CONCLUSIONS: Myopia may affect the level of trait anxiety among 13-14-year-olds. In both age groups of girls, a higher percentage of patients with high level of anxiety was discovered (≥7 sten), as compared to their peers without vision defects. Our results can contribute to a more accurate analysis of young teenagers' psychological problems, especially among boys diagnosed with myopia.

The effectiveness of a weight loss diet in a group of overweight and obese women with recurrent depressive disorders.

INTRODUCTION: The research conducted among patients with depression shows that such patients commit a range of nutritional mistakes which may predispose them to the development of many diseases including obesity and its complications. AIM OF THE STUDY: Aim of the study was to assess the effectiveness of a balanced weight loss diet in a group of women with recurrent depressive disorders. MATERIAL AND METHODS: 60 women suffering from depression, aged 41-64 (mean 52 ±5.3) on a six-month weight loss diet took part in the study. The patients' nutrition was assessed both in terms of quality and quantity, they were also subjected to anthropometric tests and their body composition was analysed. RESULTS: An average reduction in the women's body weight was 4.1 ±3.1 kg. The percentage content of the fatty tissue was reduced by 2.5 ±1.1% on average after modification of the nutrition (a statistically significant decrease in the frequency of wheat bread, cream, fat pork and eggs was observed). A considerable reduction in the mean energy value of the diet and a decrease in the total fat supply was also implemented. CONCLUSIONS: It seems that the dietary procedure which is aimed at obtaining the most advantageous effects of the reduction in the body mass of obese patients suffering from depression should be based not only on proper selection of food products and reduction in the energy value of the diet, but it should also take into account actions aimed at introducing permanent lifestyle changes including increased motivation of the patients to undertake physical activity.

Visceral obesity in normal-weight patients suffering from chronic schizophrenia.

BACKGROUND: BMI (body mass index) can be misleading regarding the level of adiposity in a normal-weight individual. Recently, a bioelectrical impedance analysis (BIA) method was developed that can measure body composition variables. The main objectives of this study were to use BIA to compare the body composition variables between chronic non-diabetic schizophrenic patients with normal weight and healthy individuals. The secondary objective was to compare the nutritional pattern of schizophrenia patients with that of matched healthy subjects, and to identify possible relationships between the content of different components of their diet and visceral adiposity. METHODS: The subjects were 52 normal-weight patients (33 males and 19 females) diagnosed with schizophrenia based on the DSM-IV and 45 (23 males and 22 females) BMI- matched controls. The patients had been receiving atypical or typical antipsychotic agents for at least one year before enrollment into the study but continuously for 3 months preceding the study and were psychiatrically stable. Body fat (kg), percent (%) body fat, fat-free mass, VAT (visceral adipose tissue) and SAT (subcutaneous adipose tissue) were measured using the bioelectrical impedance analysis (BIA) method. Daily food rations (DFR) were quantitatively evaluated by a 24-h dietary recall method covering 3 days preceding the examination. RESULTS: In normal-weight patients schizophrenia was significantly linked with higher VAT, VAT/SAT ratio and lower fat- free mass. Men had over 5 times and women over 2 times as much VAT as BMI matched groups. In women with schizophrenia and in their controls, the amount of magnesium, niacin and vitamin B6 in their diet inversely correlated with VAT, while in men lower zinc and vitamin C intake was related to higher visceral adiposity. CONCLUSIONS: Our study has shown that normal-weight patients with chronic schizophrenia have higher levels of visceral fat (VAT) than controls but similar volume of subcutaneous adipose tissue (SAT). Although no clear conclusion can be made regarding cause-and-effect relationships between the dietary content of food served to our patients and visceral obesity, we suggest that schizophrenia diet should be further investigated as a possible factor related to this type of obesity.

Association between serum testosterone levels, body mass index (BMI) and insulin in male patients with schizophrenia treated with atypical antipsychotics--olanzapine or risperidone.

OBJECTIVE: A sufficient amount of testosterone (T) is essential for adequate sexual functioning but also for cognitive and psychological well-being. Most recent studies have demonstrated that higher BMI and other symptoms of metabolic syndrome are associated with alterations in sex steroid hormone concentrations. Although, neuroleptics are known to cause a significant and sustained weight excess, the relationships between body mass index and the level of testosterone in psychiatric patients have not been thoroughly studied. The main purpose of the present study was to examine the correlations between testosterone, estradiol BMI, and insulin in male patients diagnosed with schizophrenia and treated with olanzapine or risperidone. METHODS: The study included 78 males diagnosed with schizophrenia according to the DSM-IV diagnostic classification hospitalized in psychiatric inpatient units (42 on risperidone and 36 on olanzapine). The initial and final evaluation of testosterone (T), estradiol, prolactin (PRL) and insulin serum levels were performed at week 3 and 8 after the onset of the new treatment, respectively. RESULTS: At week 3, the mean serum prolactin was markedly higher, whereas testosterone level was lower in risperidone patients compared to those treated with olanzapine. T level was negatively affected by the studied medication (risperidone), increased prolactin and a higher BMI. At week 8, the mean serum prolactin level was markedly higher in risperidone patients. Higher values of BMI and serum insulin were the most prominent factors independently associated with decreased plasma testosterone levels at that measurement point. Individual changes of T level between week 3 and 8 were positively correlated with the corresponding changes in estradiol levels. CONCLUSIONS: T serum levels appear to be independently linked with BMI, insulin and prolactin in both investigated neuroleptics. Further research is needed to elucidate the relationship between reproductive hormones and metabolic parameters in patients with schizophrenia under neuroleptic treatment.

[Does the usual dietary intake of patients with depression require vitamin-mineral supplementation?]. / Czy zwyczajowy sposób zywienia pacjentów z depresja wymaga suplementacji witaminami i skladnikami mineralnymi?

INTRODUCTION: Research on diet and nutrition of patients with depression show that their eating habits are frequently irrational and result in the inconsistent supply of nutrients, especially vitamins and minerals, the deficiency of which leads to nervous system dysfunction. AIM: The aim of the study was to evaluate the content of selected vitamins and minerals in daily food rations of patients suffering from recurrent depressive disorders. METHODS: The study involved a group of 69 people (54 women and 15 men, aged 18-65 years, mean age of women 45.7 +/- 12.2 years, men 46.0 +/- 12.2 years), treated for recurrent depressive disorders. A questionnaire designed in the Department of Dietetics and Clinical Nutrition, Medical University of Bialystok was used to collect dietary data. The quantitative assessment of eating habits used a 24-hour diet recall including 3 weekdays and 1 weekend day. RESULTS: The study showed that the supply of most nutrients assessed was inconsistent with recommendations. CONCLUSIONS: The results indicate that the need for vitamin-mineral supplementation should be considered individually. Nutritional education related to the proper choice of groups of food products is indicated at the time of clinical improvement to ensure the optimum supply of vitamins and minerals.

Nutritional values of diets consumed by women suffering unipolar depression.

BACKGROUND: Previous studies have shown that patients suffering from depression are more likely to adversely change their eating habits (eg. through increases in appetite, comfort eating and compulsive eating), which may result in an abnormal nutritional status. OBJECTIVES: To evaluate selected dietary habits, such as the number and type of meals consumed during a normal day and comparing dietary calorific values and nutritional content between women suffering unipolar depression to those without this condition. MATERIAL AND METHODS: Subjects were a group of 110 women aged 18-65 years consisting of a test group of 55 women undergoing treatment for unipolar depression at the Department of Psychiatry, Medical University of Bialystok and a control group of 55 women, without depression, attending an Obesity and Diet Related Treatment Centre. A study questionnaire was used to determine their eating habits along with other relevant data. The 24-hour diet recall method was used to obtain quantitative data collected on 3 weekdays and 1 weekend day; results being averaged. The calorific values and nutrient content of selected components, according to mealtimes, were evaluated using the Diet 5.0 computer programme. RESULTS: Those patients with depression showed that the 3 meals/day model dominated whilst the 4 meals/day model was predominant in the control group. The most frequently missed meals for both groups were afternoon tea and the mid-morning meal. Abnormalities in the calorific intake and nutritional contents from various meals were observed in women suffering depression. CONCLUSIONS: It seems appropriate to recommend that those women especially suffering from depression should consult with dieticians about their changing dietary habits, particularly for achieving the proper calorific and nutritional values/ balance from their meals.

Fasting insulin serum levels and psychopathology profiles in male schizophrenic inpatients treated with olanzapine or risperidone.

OBJECTIVE: Recent studies have suggested that higher insulin levels are associated with better psychopathology profiles in cross-sectional samples of patients with schizophrenia. This study examines whether drug-induced fasting insulin changes between third and eight week of treatment are related to clinical improvement in non-diabetic patients receiving the atypical neuroleptics: risperidone or olanzapine. METHODS: non-diabetic men with a diagnosis of schizophrenia according to the DSM-IV diagnostic classification were recruited from psychiatric inpatient units. Following a drug-free period, neuroleptic treatment was initiated (risperidone n=36, olanzapine n=35) and doses were adjusted to achieve maximal clinical efficacy. All patients were hospitalized throughout the study. Initial and final evaluations of serum insulin levels and psychopathology (assessed with the Positive and Negative Syndrome Scale, PANSS), were carried out at weeks 3 and 8 after the onset of treatment, respectively. RESULTS: There were no differences between and within the risperidone and olanzapine groups in changes of serum insulin level between the third and eighth week of treatment. In the olanzapine group, Pearson correlation analysis revealed a significant negative correlation between changes in fasting serum insulin levels and the PANSS-Total, Positive and General Psychopathology subscale scores. Only improvement in the PANSS-Negative Symptom subscale score was not correlated with insulin level change between the third and eighth week of treatment. In the risperidone group, correlations between PANSS subscales scores and the corresponding serum insulin levels change were positive, albeit statistically non-significant. In both groups the improvement in PANSS-Total scores was not correlated with changes in BMI. CONCLUSION: Olanzapine-related changes in endogenous fasting insulin levels were correlated with clinical improvement in acutely ill non-diabetic schizophrenic patients. Because the interesting linkage between insulin and positive and negative symptoms could be an epiphenomenon, randomized studies are needed to further explore the role of insulin in therapeutic responses in patients with schizophrenia.

[Functioning of the marriages applying for marital therapy]. / Funkcjonowanie malzenstw zglaszajacych sie do terapii malzenskiej.

AIM: Assessment of functioning of the marriages applying for marital therapy. METHOD: The research included 44 marriages: 22 of them were qualified for the marital therapy and 22 constituted a control group - were not taking part in therapy. Participants evaluated themselves and their relation using: SCORE-15 (Systematic Clinical Outcome and Routine Evaluation), UMACL (UWIST Mood Adjective Check List), KKM (Marriage Communication Questionnaire). RESULTS: Marriages applying for the therapy, when compared with control group, showed worse general functioning, lower adaptability, more disrupted communication and were overwhelmed by difficulties in higher degree. The lower level of engagement and support, as well as the higher level of depreciating behavior were present in their communication. In this group the lower mood expressed in lower degree of Hedonic Tone and higher degree of Tense Arousal was also recorded. CONCLUSIONS: The specific functioning of marriages in crisis applying for the marital therapy is an important indication for the family therapists, in respect to their interventions during therapy process. When working with couples, it is important to consider their difficulties in communication, the tendency to depreciating each other, the lower mood and estimating the therapy as helpful and needful with simultaneous devaluating of their own styles of coping.

Clinical and cognitive correlates of the proton magnetic resonance spectroscopy measures in chronic schizophrenia.

BACKGROUND: Proton magnetic resonance spectroscopy (1H MRS) allows for examining brain functions in vivo in schizophrenic patients. Correlations between N-acetylaspartate (NAA) level in the frontal lobe and cognitive functions and clinical symptoms have been observed. The aim of the present study was evaluation of relationship between clinical symptoms, cognitive outcomes and brain function in 1H MRS measures in schizophrenic patients. MATERIAL/METHODS: The study included a group of 47 patients with chronic schizophrenia. Patients were assessed by means of PANSS, CGI, and a battery of cognitive tests: WCST, TMT, and verbal fluency test. MRI and MRS procedures were performed. Regions of interest were located in the left frontal lobe, temporal lobe and thalamus. Metabolite (NAA, choline, myoinositol and Glx complex) ratios to creatine were calculated. RESULTS: We observed a significant negative correlation between myoinositol level in the frontal lobe and WSCT test performance. These data were confirmed by further analysis, which showed a significant correlation between WCST outcome, negative symptoms score, education level and myoinositol ratio in the frontal lobe. When analyzing negative symptoms as independent variables, the analysis of regression revealed a significant relationship between negative symptoms score and verbal fluency score, together with choline level in the thalamus. CONCLUSIONS: The above data seem to confirm a significant role of the thalamus--a "transmission station" involved in connections with the prefrontal cortex--for psychopathology development (especially negative) in schizophrenia. Moreover, our results suggest that a neurodegenerative process may be involved in schizophrenia pathogenesis.

[Family history of alcohol abuse - depressive symptoms and the quality of life in view of the MAST score of schizophrenic patients with dual diagnosis]. / Naduzywanie alkoholu w rodzinie - objawy depresyjne oraz subiektywna ocena jakosci zycia a wyniki w skali MAST u pacjentów z rozpoznana schizofrenia i alkoholizmem.

UNLABELLED: The aim of the study was to investigate the influence of familial alcohol abuse, depressive symptoms and the quality of life on MAST score in schizophrenic patients, dependent from alcohol. Material and methods. 61 patients with dual diagnosis and 60 with single diagnosis of schizophrenia performed MAST In two groups with clinical scales, depressive symptoms and the quality of life were assessed. RESULTS: Significant correlates of higher MAST scores were family history of alcohol abuse and earlier onset of alcoholism. Dissatisfaction with the quality of life was correlated with higher MAST scores but only in dependent from alcohol female schizophrenic patients. CONCLUSIONS: Symptoms of depression accompanying alcohol dependence did not influence MAST score.

[The influence of alcohol on the oral cavity, salivary glands and saliva]. / Wplyw alkoholu na jame ustna, slinianki oraz sline.

Ethanol diffuses rapidly into saliva during the drinking, and immediately after its salivary concentration is temporarily much higher than in plasma. Within 30 minutes, salivary ethanol concentration equilibrates with the plasma level, thus suggesting that ethanol easily penetrates the whole body, including oral cavity tissues and salivary glands. After alcohol intake, the level of acetaldehyde in saliva strikingly exceeds the level in systemic blood. From saliva, acetaldehyde and ethanol easily reach all local tissues. Damage to the oral tissues seems to be ascribed mostly to the action of acetaldehyde, although some acute effects depend on a direct action of ethanol and formation of reactive oxygen species (ROS) and fatty acid ethyl esters (FAEEs). It is known that the oral mucosal surface is the home of numerous normal flora microorganisms and is the portal of entry for the majority of pathogens. The oral cavity and salivary antimicrobial immune defense systems eliminate pathogens and prevent massive overgrowth of microorganisms. An oral defense system participate in the protection of not only oral tissues, but also in the protection of upper digestive and respiratory tracts, against a number of microbial pathogens. Saliva plays the role in the oral cavity lubrication, maintenance of mucosal and tooth integrity, esophageal physiology, digestion and gastric cytoprotection. As alcohol abuse affects the structure and function of oral cavity mucosa, salivary glands and saliva, the maintenance of oral and general health under normal conditions is seriously impaired during the drinking. The severe tissue damage occurs in particular when alcohol abuse coincides with smoking.

[The influence of atypical antipsychotics on brain functioning in schizophrenia. A proton magnetic resonance study]. / Wplyw leków antypsychotycznych atypowych na funkcjonowanie mózgu w schizofrenii w obrazie spektroskopii protonowej rezonansu magnetycznego.

INTRODUCTION: The influence of antipsychotic medication on brain alterations in proton magnetic resonance spectroscopy (1H MRS) in schizophrenia can be the explanation of many discrepancies observed in the previous papers. AIM: The aim of this study was the evaluation of antipsychotic medication effect on the metabolite levels in the brain of schizophrenic patients based on 1H MRS examination. METHODS: The group of 32 patients with a diagnosis of schizophrenia according to DSM-IV and 26 healthy controls were included into the study. The patients were examined twice--once after the period of at least 7 days without neuroleptics (baseline) and for the second time at least 4 weeks after stable doses ofneuroleptics (follow-up). 21 patients were receiving risperidone and 11--olanzapine. Proton resonance spectroscopy was performed on a 1.5 MR scanner. Each volume element (voxel) was localised in the left frontal lobe, in the left temporal lobe and in the left thalamus. Metabolite ratios: N-acetylaspartate (NAA) to creatine (Cr) and unsupressed water signal were analysed. Results. We found the significant increase of the NAA/Cr level in the thalamus in the group of patients treated with risperidone, we didn't observe similar changes in the olanzapine group. CONCLUSIONS: Our results confirm that the neuroleptic drugs, especially atypicals, modify brain metabolism measured by 1H MRS. The pattern of the changes suggest a possible neuroprotective influence of the antipsychototic treatment in schizophrenic patients. The small group of the olanzapine treated patients doses not allow to make any conclusions regarding this type of medication.

[Biomarkers of alcohol abuse. Part II. New biomarkers and their interpretation]. / Biomarkery naduzywania alkoholu. Czesc II. Nowe biomarkery oraz ich interpretacja.

An increasing number of new biomarkers of alcohol abuse appear in the literature. The most commonly used biomarkers (5-hydroxytryptophol, fatty acid ethyl esters, ethyl glucuronide, phosphatidyl ethanol, ethyl sulphate, mitochondrial aspartate aminotransferase, carbohydrate deficient transferrin, acetaldehyde adducts, beta-hexosaminidase, and sialic acid) were described. Then other known and less known biomarkers associated with alcohol abuse were described in brief (e.g. acetaldehyde, acetate, methanol, alpha-amino-n-butyric acid, dolichol, proteomics). Their sensitivity and specificity is generally higher than that of traditional biomarkers. The time of detection in biological fluids occur from one day to few months after alcohol consumption. Hence, their usefulness in clinical practice as well as in experimental studies is increasing.

[Biomarkers of alcohol abuse. Part I. Traditional biomarkers and their interpretation]. / Biomarkery naduzywania alkoholu. Czesc I. Biomarkery tradycyjne i ich interpretacja.

Approximately 15% of the Polish population abuse alcohol. Early detection of alcohol problems may prevent their further development and progression. The study reviews traditional biomarkers associated with alcohol abuse. The nature of biomarkers, their practical application and limitations in alcohol abuse detection, in assessment and monitoring of drinking, are reviewed. Despite the limited sensitivity and specificity in alcohol abuse detection, traditional biomarkers remain useful in alcohol abuse detection. They are widely available and relatively inexpensive, providing valuable data on complications of drinking and prognosis as well as on concurrent conditions affected by drinking.

Salivary Carbohydrate-Deficient Transferrin in Alcohol- and Nicotine-Dependent Males.

Serum carbohydrate-deficient transferrin (CDT), an 80 kDa glycoprotein, is one of the most commonly employed biomarkers to detect alcohol dependence. Some salivary glycoproteins such as α-amylase, clusterin, haptoglobin, light/heavy-chain immunoglobulin, and transferrin, which alter glycosylation in alcohol-dependent persons, have been suggested to be potential alcohol markers. However, their identification is based on indirect analysis of lectin glycosidic bonds and molecular weight. We investigated the CDT content in the saliva of alcohol- and nicotine-dependent men. The CDT concentration (ng/mL, ng/mg protein) was determined by an Enzyme-Linked Immunosorbent Assay (ELISA) commercial kit in 55 men: 20 healthy social drinkers (C), 10 chronic cigarette smokers (S), 10 alcohol-dependent non-smokers (A), and 15 alcohol-dependent smokers (AS). Surprisingly, there were no differences in the concentrations of CDT between the studied groups. Salivary pH was the lowest in the AS and the highest in the A group. Therefore, salivary CDT cannot be used as an alcohol dependence marker as measured by ELISA. We suggest that direct identification of glycoproteins is necessary to search for potential salivary alcohol biomarkers. Molecules smaller than 40 kDa, which easily translocate from blood to the saliva, might be preferred as salivary alcohol markers.

Effect of risperidone and olanzapine on reproductive hormones, psychopathology and sexual functioning in male patients with schizophrenia.

OBJECTIVE: To study the effect of drugs on the hypothalamo-pituitary-gonadal (HPG) axis we compared the endocrine actions of two neuroleptics with different receptor affinity profiles-risperidone and olanzapine in male schizophrenic patients. METHODS: We investigated the levels of prolactin, estradiol, testosterone, LH, FSH and testicular peptide hormone-inhibin B, and we assessed psychopathology (PANSS), sexual function (ASEX) and treatment adherence (DAI-10) in 89 male schizophrenic inpatients treated with olanzapine or risperidone administered orally. The initial and final evaluations were carried out at weeks 3 and 8 after the onset of treatment, respectively. RESULTS: At initial evaluation the mean serum prolactin and inhibin B levels were markedly higher, whereas testosterone level was lower in patients treated with risperidone, than in those treated with olanzapine. In 5 out of 50 subjects from risperidone group (10%) and in 1 from olanzapine group (2.6%) testosterone levels were below the lower limit (<241ng/ml), which reflected Leydig's cell impairment. In one patient receiving risperidone and in three receiving olanzapine, inhibin B level was below 80pg/ml, indicating Sertoli's cell dysfunction. At the final evaluation the mean serum prolactin level was markedly higher in patients taking risperidone, whereas their FSH levels were lower than in patients receiving olanzapine. In all investigated groups, except for the risperidone-hyperprolactinemic group inhibin B levels were negatively correlated with serum FSH. The mean LH, FSH, testosterone and estradiol levels were within the normal reference range at initial and final evaluation. The non-adherence to medications and ASEX scores were significantly higher in risperidone groups. Sexual dysfunction and medication non-adherence was not related to prolactin or gonadal hormone levels. CONCLUSIONS: Risperidone elicited higher PRL elevation than olanzapine. Treatment with this medication can be associated with disturbances in reproductive hormones (testosterone) and gonadotropins (FSH). The cause of olanzapine-elicited reduction of inhibin B level and the lack of negative correlation between FSH and inhibin B in patients with risperidone-induced hyperprolactinemia require further investigation. Patients receiving risperidone showed higher level of sexual dysfunction and treatment non-adherence than those treated with olanzapine.

Catabolism of salivary glycoconjugates in acute ethanol intoxication.

BACKGROUND: The aim was to study the effects of a single large dose of ethanol (approximately 2.0 g/kg of body weight, as 40% vodka) on the specific activities of alpha-mannosidase, alpha-fucosidase, beta-glucuronidase, and beta-galactosidase as well as on the total protein concentration in saliva in eight healthy young volunteers. MATERIAL/METHODS: Resting whole saliva samples were collected 12 hours prior to and 36 and 108 hours after alcohol consumption. Exoglycosidase activities were assayed in the supernatants by the colorimetric method. Protein content was determined by the Lowry method. RESULTS: Thirty-six hours after alcohol consumption the specific activities of alpha-fucosidase and beta-glucuronidase were significantly higher than before drinking. The specific activity of beta-galactosidase showed a greater tendency to increase than alpha-mannosidase after the drinking session. The total protein concentration was significantly lower after alcohol consumption than at baseline, even at 108 hr. Significant inverse correlations between total protein content and the specific activities of the exoglycosidases in saliva were found after the drinking session. CONCLUSIONS: Acute ingestion of a large dose of ethanol increased the activity of salivary exoglycosidases, which might be followed by subsequent degradation of proteins in saliva. The observed changes might contribute to salivary defense system malfunction as well as to oral malodor production.

The assessment of satisfaction of energy demand and of chosen macro - and micro-element content in the daily food rations of women diagnosed with schizophrenia with varied nutritional states. / Ocena realizacji potrzeb energetycznych oraz udzialu wybranych makro- i mikroskladników w calodziennych racjach pokarmowych kobiet z rozpoznaniem schizofrenii o zróznicowanym stopniu odzywienia.

OBJECTIVES: The aim of the study was to assess the degree of satisfaction of the daily demand for energy and chosen nutrients in the diets of women with schizophrenia, depending on the nutritional state of the subjects, assessed on the basis of the chosen anthropometric and metabolic parameters. METHODS: The study covered 102 women aged 21-64 (50 women diagnosed with schizophrenia and 52 healthy volunteers) aged 21-64 years. A 24-hour diet recall was used in the quantitative nutritional assessment. The anthropometric and biochemical measurements and the body composition analysis were used in the assessment of the nutritional state. RESULTS: The food rations of patients diagnosed with schizophrenia were characterized by a significantly higher intake of saturated fatty acids and a lower intake of vitamin C, B12, folates, and sodium as compared to healthy women. It was noted at the same time that the food rations of patients from both groups provided too low amounts of polyunsaturated fatty acids, vitamin D, folates, potassium, calcium, iron, and dietary fiber. Too high intake was observed in the case of vitamin A, B2, B6, sodium, and phosphorus in both groups. Total fat body mass of women with schizophrenia was significantly correlated with intake of saturated fatty acids, whereas the visceral adipose tissue content was significantly correlated with the carbohydrate intake, and the subcutaneous adipose tissue content - with the total fat and saturated fatty acids intake. CONCLUSIONS: The diet of women diagnosed with schizophrenia did not deviate from the diet of healthy persons, although the nutritional mistakes that were made by them suggest to choose the nutritional therapy individually for each patient, after carrying out a detailed nutritional interview.
