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

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.

Does the usual dietary intake of schizophrenia patients require supplementation with vitamins and minerals?

OBJECTIVES

The aim of the study was to assess the supply of selected vitamins and minerals in the daily food rations of patients diagnosed with schizophrenia.

METHODS

62 schizophrenia patients (32 women and 30 men aged 21-64, the mean age of women was 41.3 ± 11.2, the mean age of men was 36.1 ± 9.7) took part in the study. A 24-hour diet recall from 3 weekdays and 1 weekend day was used for quantitative assessment of the diet.

RESULTS

In the conducted research, it was shown that, despite ensuring the average supply of energy required for a given age and sex group, the food rations of patients of both sexes were characterized by a deficiency of vitamin D, folates, potassium, calcium, and also vitamins E and C, magnesium in men as well as iron and iodine in women. Excessive amounts of vitamins B2, B6, sodium, and phosphorus were found in food rations of persons of both sexes and vitamins A, B1, niacin in food rations of women and also vitamin B12 in food rations of men.

CONCLUSIONS

No supplementation of schizophrenia patients' diet is recommended; it is only justified in individual cases of patients in whom vitamin and mineral deficiencies were found on the basis of analysis of their food habits. However, it is necessary to provide each schizophrenia patient with appropriate food education that will allow them to choose products that contain all nutrients needed for proper functioning of the body, including the central nervous system.

Proton magnetic resonance spectroscopy changes in a longitudinal schizophrenia study: a pilot study in eleven patients

PURPOSE

Investigation of the longitudinal effect of schizophrenia on changes in various brain-metabolite levels and their relationships with cognitive deficits that have not been fully explained yet.

METHODS

Five years subsequent to their first examination for their first episode of schizophrenia, eleven patients from an original group of 30 were reexamined. Their cognitive functions were assessed with the Wisconsin Card Sorting Test. Magnetic resonance imaging and proton magnetic resonance spectroscopy were performed on a 1.5 T scanner. Voxels of 8 cm³ were positioned in the left frontal lobe, left temporal lobe, and the left thalamus. The study had a naturalistic design, and patients were treated with various antipsychotics.

RESULTS

No significant statistical differences between the baseline and follow-up in N-acetylaspartate (NAA:creatine plus phosphocreatine [Cr] and NAA/H₂O) levels were observed in any region of interest. We found a significant statistical correlation between 5-year difference in frontal NAA/Cr levels and duration of the last antipsychotic treatment in this period (R=0.908, P=0.012). We found a trend (P=0.068) toward lower choline-containing compounds (Cho/Cr ratio) in the temporal lobe over 5 years and a trend (P=0.079) in higher glutamate-glutamine- GABA (Glx/H₂O) levels in the left thalamus. The patients showed social and clinical improvement at follow-up examination, and there were no changes in Wisconsin Card Sorting Test results.

CONCLUSION

The observed tendency toward decline in choline ratio might have been due to decreased temporal cell density or impaired neuron-membrane or myelin functions. A tendency for higher Glx levels suggest the involvement of thalamus dysfunction in the chronic schizophrenia process. The lack of NAA decrease might have been due to effective antipsychotic treatment. Further longitudinal studies on large patient groups are required to confirm these metabolic changes in schizophrenia.

How do patients perceive ambulatory psychiatric care and what are their needs?

INTRODUCTION AND OBJECTIVE

The quality of a doctor-patient relationship plays a vital role in all fields of medicine. In the case of psychiatry, this role is special as it provides the foundation for the whole therapeutic process. The aim of this study was to investigate the patient's perspective on psychiatric visits: patient's attitudes towards the psychiatrist, patient's view of the patient-psychiatrist relationship, and the patient's needs and expectations from this relationship.

MATERIAL AND METHODS

615 psychiatric outpatients responded to the anonymous questionnaires connected with their attitudes towards the psychiatrist, evaluation of the doctor, and expectations from psychiatric care. The study was conducted in 10 out of 30 public centres for psychiatric care in north-eastern Poland.

RESULTS

Generally, the patients liked and positively evaluated their psychiatrists. Patient's liking for the doctor was connected with the feeling that the doctor also liked the patient, as well as with perceiving the doctor as competent and willing to meet the patient. The longer the treatment with a particular psychiatrist and the rarer need to consult the doctor, the more positive attitude and evaluation of the doctor patients had. According to the patients, the most significant expectations were associated with both conversation with the doctor and receiving emotional support.

CONCLUSIONS

The key phase for forming the patient-psychiatrist relationship was the first stage of cooperation in which patients created their attitudes towards the doctor without modifying them at further stages. Thus, further studies on learning and developing the ability to establish the relationship with the patient, inspiring the patient's trust and making psychiatric appointments comfortable from the first meeting, will be highly valuable.

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.

Eating habits and nutritional status of patients with affective disorders and schizophrenia

OBJECTIVES

The aim of the study was to assess the nutritional value of the food intake in the group of men and women suffering from recurrent affective disorders and schizophrenia, and also to determine the relation between selected nutritional parameters with anthropometric indices defining the nutritional status of the subjects.

METHODS

219 persons participated in the study (61 patients with recurrent depressive disorders, 60 patients with schizophrenia and 98 healthy volunteers). A24-hour dietary recall was used in the quantitative assessment of the diet. Anthropometric and biochemical measurements as well as body composition analysis were used to assess the nutritional status.

RESULTS

It was shown that women with depression and schizophrenia had a significantly higher content of both visceral adipose tissue and subcutaneous adipose tissue as compared with the control group. A diet with a higher content of energy from protein, a higher supply of calcium promoted a lower fat content in the bodies of women suffering from depression (no such relationship was observed in the group of men). In the group of patients with schizophrenia, a diet with a lower supply of energy promoted a lower BMI value, waist circumference, lower waist-hip ratio and a lower fat content in the body.

CONCLUSIONS

An improper energy structure and an improper content of nutrients can, in the future, contribute to the development of many somatic diseases, thus leading to deterioration of life quality of subjects and preventing the maintenance of mental health.

Assessment of dietary habits and nutritional status of depressive patients, depending on place of residence

INTRODUCTION AND OBJECTIVES

An increased incidence of depressive disorders observed in recent years in the Polish and world population is a serious health problem. The aim of the study was to compare dietary habits and nutritional status of patients with recurrent depressive disorders, depending on their place of residence. Their impact on selected metabolic parameters was also considered.

MATERIAL AND METHODS

The study group comprised 96 women and 84 men reporting to the Outpatient Mental Health Clinic at the Department of Psychiatry, Medical University of Bialystok in north-eastern Poland. The average age of the women was 46.7±11.7 years, and of men 47.0±11.3 years. In the quantitative assessmentof diets, 24-hour food recall interviews were conducted. Assessment of the nutritional status of the respondents consisted of anthropometric measurements, body composition analysis and biochemical parameters.

RESULTS

It was show that the diets of female urban inhabitants were characterized by a significantly lower energy value and total fat content, compared to their rural counterparts. The food rations of men living in the city had a significantly higher energy value, protein content and total FAT, compared to rural residents. It was also noted that urban residents of both genders were characterized by a lower percentage of body fat, both visceral and subcutaneous (women), and a higher water content than rural residents.

CONCLUSIONS

The study showed dietary errors in all compared groups, regardless of place of residence, which was reflected in the nutritional status of the respondents. The results also indicated that during the declared change in dietary habits, the treatment of depressive patients should include dietary instructions in order to ensure an optimum supply of nutrients.

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.

Incidence of postpartum depression and couple relationship quality

OBJECTIVES

The childbirth constitutes a significant event in a woman's life and in the marital/ couple dyad. The changes which follow childbirth require re-organization of previous coping styles and development of new methods of adaptation, which proves difficult. The current study evaluated to what extent the development of postpartum depression symptoms in new mothers was associated with their level of satisfaction in marital relationship.

METHODS

The study included 100 women in their first month after delivery. The women completed questionnaires regarding postpartum depression (Postpartum Depression Screening Scale) and marital relationship quality (Marital Compatibility Questionnaire).

RESULTS

There was a significant correlation between the level of postpartum depression and relationship quality. A greater severity of postpartum depression symptoms (sleeping/ eating disturbances, anxiety/insecurity, emotional lability, mental confusion, loss of self, guilt/ shame, suicidal thoughts) occurred in women who were less satisfied with their relationship, i.e., those who experienced a decreased level of intimacy, self-fulfillment and partner similarity, as well as a deeper sense of disillusionment. Women who declared deeper satisfaction with their relationship displayed a greater sense of mental well-being. No correlation was found between the occurrence of postpartum depression and socio-demographic factors (age, education level, place of residence) and factors associated with the subjects' childbearing history (number of children, number of pregnancies, history of miscarriage, family planning, prior diagnosis of depression, type of delivery, newborn's condition following birth, infant feeding method).

CONCLUSIONS

Patients dissatisfied with the quality of their marital relationship experienced an increased severity of postpartum depression symptoms. Greater satisfaction with relationship quality was expressed by women in formalized relationships.

Neurochemical alterations in anterior cingulate cortex in bipolar disorder: a proton magnetic resonance spectroscopy study (1H-MRS)

OBJECTIVES

The aim of this study was to determine neurochemical alterations in bipolar disorder using proton magnetic resonance spectroscopy (1H-MRS).

METHODS

We investigated a group of 27 patients diagnosed with bipolar disorder (with manic and mixed episodes, depression and after remission of symptoms) and 10 healthy subjects. MR imaging and 1H-MRS were performed on a 1.5 T scanner. Voxels of 8 cm3 were positioned in the anterior cingulate, left frontal lobe and left temporal lobe. Spectral peaks of NAA (N-acetylaspartate), Glx (glutamate/glutamine/GABA complex), Cho (choline), Cr (creatine/phosphocreatine) and mI (myo-inositol) were analyzed and the ratios of these metabolites to creatine (Cr) and non-suppressed water signal were determined.

RESULTS

In the anterior cingulate cortex of patients with bipolar disorder a significantly higher Cho/H2O ratio (p = 0.029) and a trend toward higher Cho/Cr ratio values (p = 0.096) were observed as compared to healthy controls.

CONCLUSIONS

The findings of our study prove that neurochemical changes occurring in the anterior cingulate cortex of bipolar patients are related to altered choline levels.

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.

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.

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?]

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.

The effect of chronic alcohol intoxication and smoking on the output of salivary immunoglobulin A

The effect of chronic alcohol intoxication and smoking on the output of salivary immunoglobulin A (IgA) was studied in 37 volunteers: 17 male smoking patients after chronic alcohol intoxication (AS) and 20 control non-smoking male social drinkers (CNS). The DMFT index (decayed, missing, or filled teeth), gingival index and papilla bleeding index (PBI) were assessed. Concentration of IgA in saliva was determined by ELISA. Salivary flow (SF) and IgA output were significantly decreased in AS compared to CNS. There were no significant correlations between the amount of alcohol/cigarettes as well as the duration of alcohol intoxication/smoking, and SF or IgA output, nor between IgA level and SF. Gingival index was significantly higher in AS than in CNS, and was inversely correlated with IgA salivary level. The worsened periodontal state in smoking alcohol-dependent persons may result from diminished IgA protection of the oral tissues due to its decreased output.

Proton magnetic resonance spectroscopy measures related to short-term symptomatic outcome in chronic schizophrenia

INTRODUCTION

Proton magnetic resonance spectroscopy (¹H MRS) enables the evaluation of in vivo brain function. The purpose of the study was to compare ¹H MRS measurements in schizophrenic patients, who were clinical responders after short-term antipsychotic treatment, with non-responders and healthy controls.

METHODS

We investigated a group of 47 patients diagnosed with schizophrenia. Patients were examined twice--once after a period of at least 7 days without neuroleptics and the second time at least 4 weeks after therapy with stable doses of medication. The follow-up was available in 42 patients. Baseline MRS measurements of clinical responders were compared with non-responders and the group of healthy controls (N=26). We assessed the following metabolite ratios: NAA (N-acetylaspartate), Glx (complex of GABA, glutamine and glutamate), Cho (choline) and mI (myo-inositol) to creatinine (Cr) in the left frontal and temporal lobes and the thalamus.

RESULTS

Responders showed a significantly lower baseline frontal Glx/Cr level than non-responders. Both groups had a significantly lower NAA/Cr ratio in the frontal lobe than the controls, but only non-responders had a significantly lower NAA/Cr ratio in the thalamus.

CONCLUSIONS

Our results confirm the relationship between the glutamatergic system and pathophysiology of schizophrenia and suggest a significant value of ¹H MRS examination in the assessment of the future treatment effect.

[Functioning of the marriages applying for marital therapy]

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.

Proton magnetic resonance spectroscopy changes after antipsychotic treatment

Proton magnetic resonance spectroscopy ((1)H MRS) enables the observation of brain function in vivo. Several brain metabolites can be measured by the means of (1)H MRS: N-acetylaspartate (NAA), choline containing compounds (Cho), myo-inositol (mI) and glutamate (Glu), glutamine (Gln) and GABA (together as Glx complex or separately). (1)H MRS measures have been found to be abnormal in psychotic disorders such as schizophrenia. Here we specifically review the influence exerted by antipsychotic drugs on brain metabolism, as detected by (1)H MRS. We systematically reviewed the available literature and uncovered 27 studies, 16 before-after treatment and 11 cross-sectional. Most of them addressed the effects of antipsychotics in schizophrenia and mainly focusing on NAA alterations. Follow up studies indicated antipsychotic drugs may act by increasing NAA levels in selected brain areas (the frontal lobe and thalamus), especially during the short-time observation. This phenomenon seems to vanish after longer observation. Other studies indicated that glutamate measures are decreasing along with the duration of the disease, suggesting both a neurodegenerative process present in schizophrenic brain as well as an influence of antipsychotics. The above results were reviewed according to the most recent theories in the field accounting for the impact of antipsychotics (1)HMRS measures.

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.

The effect of chronic alcohol intoxication and smoking on the activity of oral peroxidase

Peroxidase is the most important antioxidant enzyme in saliva. Through peroxidation of thiocyanate in the presence of H₂O₂, peroxidase catalyses the formation of bacteriocidic compounds such as hypothiocyanate.The purpose of this study was to evaluate the effect of chronic alcohol intoxication and smoking on the activity of oral peroxidase (OPO). A total of 37 volunteers participated in the study. This cohort consisted of 17 male alcohol-dependent smoking patients after chronic alcohol intoxication (AS group, alcohol + smoking) (mean age: 42 years; range: 26-55) (100-700 g/day of alcohol; 10-20 cigarettes/day) and 20 control male social drinkers(CNS group, control non-smokers) with no history of alcohol abuse or smoking (mean age: 42 years; range:30-53). Salivary peroxidase activity was measured by the colorimetric method. The differences between groups were evaluated using the Mann-Whitney U test. There was significantly higher activity of OPO (p = 0.00001)and significantly lower salivary flow (SF) (p = 0.007) in alcohol-dependent smokers after chronic alcohol intoxication compared to the control group. OPO activity significantly correlated with the number of days of alcohol intoxication, but not with smoking. Gingival index (GI) was significantly higher in smoking alcohol-dependent persons than in the control group, and correlated with OPO activity. The sensitivity of the OPO test was 70% in smoking alcoholics, while specificity was 95%. The increased activity of OPO suggests chronic oxidative stress is more likely due to ethanol action than to smoking. Smoking alcohol-dependent persons have a worse periodontal status than controls. OPO activity as a marker of chronic alcohol abuse may help in the diagnosis of alcoholism.

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]

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.

Proton magnetic resonance spectroscopy study of brain metabolite changes after antipsychotic treatment

INTRODUCTION

Proton magnetic resonance spectroscopy (¹H MRS) enables the observation of brain function in vivo. The aim of our study was to evaluate the effects of antipsychotic medication on metabolite levels in the brain of schizophrenic patients based on a ¹H MRS examination.

METHODS

We examined 42 patients previously diagnosed with chronic schizophrenia twice: firstly, after the neuroleptic wash-out (baseline) and secondly, under stable medication (follow-up, after treatment). The study had a naturalistic design and several different neuroleptic medications were used during the treatment phase. The clinical evaluation, MRI and MRS procedures were performed. The group of 26 healthy controls were also examined to compare MRS results.

RESULTS

We found a significantly lower NAA/Cr (N-acetylaspartate/creatine) ratio in the frontal lobe and thalamus in patients (after the wash-out) as compared to controls. After treatment a significant decrease of the Glx/Cr ratio in the temporal lobe and a trend for an increase of the NAA/Cr ratio in the thalamus were observed.

CONCLUSION

Our results confirm that antipsychotic medication modifies brain metabolism measured by means of ¹H MRS. The pattern of the changes suggests a neuroprotective action of antipsychotic medication in schizophrenia.

[The influence of alcohol on the oral cavity, salivary glands and saliva]

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]

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]

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]

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.

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.

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.

[Impact of neuroleptic-induced hyperprolactinemia on sexual dysfunction in male schizophrenic patients]

Human sexual function is complex and effected in many different ways by schizophrenia and the antipsychotic drugs used in its treatment. Although not extensively researched, sexual dysfunction seems to be frequent in patients with schizophrenia, especially in men. They appear, in significant part, to be a direct consequence of dopamine antagonism, combined with indirect effects due to increased serum prolactin (PRL) concentration. All of the typical antipsychotics and risperidone can cause substantial PRL elevation. Hyperprolactinemia in male schizophrenics might decrease libido, cause anorgasmia and lead to erectile dysfunction. These sexual side effects are closely associated with the patients' willingness to take antipsychotics, and can affect compliance.

[Impact of alcohol dependence on the course and psychopathology of schizophrenia]

AIM

The study was undertaken to investigate possible influence of alcoholism on the course and psychopathology of schizophrenia.

METHOD

A representative sample of 61 subjects was selected from schizophrenic patients with a history of alcohol dependence (dual diagnosis) registered in the period of 1997-2000. They were compared with 60 control patients with a single diagnosis of schizophrenia. In two groups, with the interview and clinical scales, the onset, course and psychopathology of schizophrenia were assessed.

RESULTS

Male patients with schizophrenia and alcohol dependence had a later mean age at onset of mental illness, women--a higher rate of alcohol abuse in the family compared to the control groups. In men with dual diagnosis, the negative symptoms were less prominent. Women with schizophrenia and alcohol dependence reported more depressive symptomatology.

The effect of risperidone on metabolite measures in the frontal lobe, temporal lobe, and thalamus in schizophrenic patients. A proton magnetic resonance spectroscopy (1H MRS)

OBJECTIVE

The aim of the study was the evaluation of risperidone effect on metabolite measures in the frontal lobe, temporal lobe and thalamus in schizophrenic patients on the basis of proton magnetic resonance spectroscopy ( (1)H MRS).

METHODS

A group of 14 patients with the diagnosis of schizophrenia, according to DSM-IV, were examined in the study. The patients were examined twice, once after a period of at least 7 days without neuroleptics and for the second time at least 4 weeks after stable risperidone doses.

RESULTS

The significant differences in the metabolite levels before and after the treatment were observed only in thalamus: an increase in myoinositol (mI) and N-acetylaspartate (NAA) levels. Positive symptoms before the treatment correlated positively with NAA level in the frontal lobes and negatively in the temporal lobes. Negative symptoms before the treatment correlated positively with Glx (a common signal for GABA, glutamine and glutamate) level in the temporal lobes.

CONCLUSION

Our results seem to confirm the influence of risperidone on the brain metabolism, specifically in the region of thalamus.

[The effectiveness of psychoeducation in schizophrenic and depressive patients--preliminary report]

Earlier studies suggest that psychoeducation as a form of psychosocial care is of value in improving the patient's attitude towards mental illness as well as in reducing and delaying the relapse rates of both--psychotic and depressive disorders.

AIM

The aim of this study was the evaluation of influence of psychoeducation on clinical symptoms, quality of life and drug attitude in schizophrenic and depressive patients.

METHOD

52 patients, aged 18-50 years, hospitalized in the Department of Psychiatry of Medical Academy in Białystok, were involved in the study. They were randomly assigned into 2 groups: on medication without psychoeducation (12 schizophrenics, 12 depressive patients) and on medication and psychoeducation (16 schizophrenics and 12 depressive patients). The patients were assessed by means of BPRS, BNS, IMHC 2000, Raskin/Covi Scale, DAI-10. The assessment was performed twice--shortly after admission and before discharge from the hospital.

RESULTS

The patients in both groups showed improvement in symptoms and in quality of life. Patients on psychoeducation changed their drug attitude positively significantly more often.

CONCLUSION

Knowledge about the positive influence of medication on psychiatric symptoms helps to improve compliance and improves the course of disease.
