Background: Biological markers for chronic alcohol consumption like MCV or gammaGT or carbohydrate deficient transferrin (CDT) are useful, but far from being perfect. In patients with liver disease a reliable marker for chronic alcohol consumption as the underlying etiology is highly needed. Recently, a new ELISA based version of the carbohydrate-deficient-transferrin (CDT-TRISIALO (-)) assay has been developed, which measures asialo-, monosialo- and disialo transferrin, but excludes trisialo- transferrin; that modification suggests higher sensitivity and specificity in detecting recent alcohol consumption in patients., Aims: The study goal was to evaluate the sensitivity, specificity, positive and negative predicitive value of this new carbohydrate-deficient-transferrin assay (CDT-TRISIALO (-)) in a group of patients with liver disease and to compare the results with that of the established CDT assay (CDT-TRISIALO (+))., Patients and Methods: Our study population consisted of 110 consecutive patients (male: n = 80 [72.7 %], female: n = 30 [27.3 %]) with liver disease of the following etiologies: chronic alcohol consumption (n = 51 [46.4 %]; Out of them 30 alcohol abusing patients were assessed by cage = 1 and 21 alcohol dependent patients were assessed by cage = 2, chronic viral hepatitis (n = 33 [30.0 %]) including 25 [22.7 %] patients with chronic hepatitis C infection and 8 [7.3 %] patients with chronic hepatitis B infection), haemochromatosis (n = 4 [3.6 %]), mechanical cholestasis (n = 17 [15.5 %]) and other liver diseases (n = 5 [4.6 %] including autoimmune hepatitis (n = 2) and primary biliary cirrhosis (n = 3)). 27.3 % of our patients (n = 30) had no liver cirrhosis whereas the majority (72.7 %, n = 80) had liver cirrhosis., Results: In our population of liver disease patients the CDT-TRISIALO (-) assay had a sensitivity of 72.7 % and specificity of 58.1 % for recent alcohol consumption at the published cutoff level of 2.6 %. The positive predictive value was 34.0 % and the negative predictive value was 87.8 %. Sensitivity and specificity of the CDT-TRISIALO (+) assay at the recommended cutoff level of 4.7 % were similar, 77.3 % and 49.3 %, respectively. The positive and negative predictive values were 30.9 % and 88.1 %. CDTTRISIALO (+) and CDT-TRISIALO (-) levels increased significantly with higher Child-Pugh stages., Conclusion: The newly developed carbohydrate deficient transferrin test (CDT-TRISIALO (-)) is of no advantage as compared to the established assay (CDT-TRISIALO (+)) when used in a patient population with liver disease. In that population, normal CDT-TRISIALO (-) helps to exclude recent alcohol consumption; this results from the high negative predictive value of a normal CDT-TRISIALO (-).

Gamma-hydroxybutyric acid is a gamma-aminobutyric acid analogue which can be found in the human brain and is believed to be a neurotransmitter in the central nervous system. In animal experiments as well as in humans gamma-hydroxybutyric acid has been shown to alleviate the symptoms of the alcohol withdrawal syndrome. 299 patients, who were admitted to hospital for reasons primarily unrelated to their alcohol dependence, were treated with gamma-hydroxybutyric acid when symptoms of the alcohol withdrawal syndrome occurred. Gamma-hydroxybutyric acid was usually given at a daily dose of 50 mg/kg in 3 divided doses, the clinical course of the patients was followed for 7 days or until discharge from hospital. Patients were 214 men and 82 women aged 18-87 years. The reasons for admission to hospital were frequently internal diseases, neurological/psychiatric problems, trauma or surgery. At the start of gamma-hydroxybutyric acid treatment, tremor was present in 81% of patients, sweating in 76% and unrest in 92%. Symptoms occurred 1-72 hours after admission. The efficacy of gamma-hydroxybutyric acid to ameliorate or suppress the symptoms of the alcohol withdrawal syndrome was judged to be excellent in 57%, good in 34%, fair in 18%, insufficient in 3% of patients. Drug tolerance was judged to be excellent in 79%, good in 17%, fair in 2% and poor only in 1% of patients. Adverse events were rare and mild. It is concluded that gamma-hydroxybutyric acid is an attractive alternative to tranquilizers in the management of the alcohol withdrawal syndrome in hospital.

Concrete cross-sectional studies of the organic brain syndrome, carried out periodically, attempt to establish for the parameters evaluation of substrate damage--and different noopsychopathological rating-scales for the measurement of brain capacity impairment. Beyond the level of the purely correlative-statistical point of view of the relationship between parameter and score changes, demanding for a quantitative model which could provide not only a description, but also an explanation for such a relationship. The fact that there can only be a question here of a "quantitative causality" embracing non-specificity of toxic substances and relative to acute and chronic diffuse organic brain syndromes. It results, that quantitative causality meets the requirements of an exponential function model and that one can validate such models through correlative-statistical methods. This has already been carried out by Ball and Taylor.

This paper presents a literature review as well as a study in 13 patients suffering from delusion of infestation. Symptoms found in MMPI are related to clinical experience. Our results suggest the distinction of three different groups of these patients: 1. Patients with predominantly hypochondric traits, with a distinct conviction to suffer from a severe, physical illness that is often looked at as incurable (hypochondriacal delusion of parasitosis). 2. Patients with paranoid symptoms and without hypochondric apprehensions. These patients usually hopelessly fight against their parasites, that impair their sphere of existence. Physical illness is denied. ("delusion of infestation"). 3. Patients with signs of both, hypochondrical as well as paranoid delusions ("hypochondriacal delusion of infestation").

In 34 patients suffering from delusional parasitosis the relevance of an accurate differential diagnosis with respect to pharmacological treatment was investigated. Under a psychopharmacological therapy of the delusion's additional psychiatric symptomatology in 17 patients (50%) a full remission and in other 5 patients an improvement of the delusional symptoms was observed. The unexpected high recovery-rate is explained by the fact that all of the patients with additional depression showed a reduction also of the delusional symptomatology after a treatment with antidepressants. In contrast to that, patients with organic brain syndromes underlying the delusions had a significant worse outcome, which seems to be caused by the considerable lack of effective psychopharmacological treatment of such states. The results indicate that an accurate psychiatric differential diagnosis is of great importance for the psychopharmacological therapy of patients suffering from delusional parasitosis. In this context the Viennese decision-tree for delusional syndromes is discussed.

In this study 444 chronic alcoholic patients, hospitalized at the beginning of this study, were followed up for 4 to 7 years (31). During this time 101 patients died (23.2%), with whom severeness of disease as well as the extent of social depravation could be identified as factors influencing mortality. Beginning in January of 1982 we investigated mortality of the population of a village with a similar socio-cultural background (working situation, rural population, wine-growing area). As it was possible to cooperate with the local general practitioner, who has been living and working in this village since 1946, knowing all the troubles and sorrows, we could get data of each person having died. We collected data on each dead of this village until we had 101 definitely not alcohol addicted cases as control group. For getting this number of cases we had to investigate data of 116 dead, because 15 of them met the diagnostic criteria for chronic alcoholism. Sociodemographic data, social development, diseases and causes of death were recorded in all groups of investigation. In the group of formerly hospitalized chronic alcoholic patients we found a preponderance of men as well as a significantly shorter life-time (alcoholic group: 50 +/- 9.8 years, control group 73.9 +/- 12.5 years). Besides alcohol misuse other factors influencing mortality could be elaborated (e. g. stressing or discriminating working situation, incontinuous and/or unsatisfying partnership, additional criminal acts etc.) separating the chronic alcoholic group (with former hospitalisation) from the control group in a significant way. Concerning the disease leading to death, chronic alcoholic patients more frequently had suffered from liver damage (with break of oesophagus blood vessels) as well as from auto-destructive behaviour patterns (like suicide, masked accidents) compared to the non-alcoholic group. This control group died significantly more frequent because of cardio-vascular diseases, often accompanied by cerebral deficits.

13 cases of politoxicomania that had undergone stationary treatment and, at the time of observation, were in rehabilitation, comprised the case load of this study. They were compared with 10 test persons in good state of health. In order to obtain circadine hormone profiles for melatonine, cortisol, human growth hormones (HGH) and thyroid stimulating hormones (TSH), blood samples were taken every hour from 6 pm until 7 am the following morning. The test cycle commenced with obtainment of a biochemical blood profile and a drug-oriented urine analysis. The cases were assorted into three therapy groups: Group 1: complete abstinence. Group 2: no hard drug intake. Group 3: acute relapse after a prolonged period of abstinence. This categorization (i.e. abstinence, soft or hard drug intake) was clearly mirrored by significant differences in the hormone profiles: the group of "abstinents" showed remarkably higher melatonine and cortisole levels than the acute relapsive cases. HGH and TSH profiles showed partly pathological levels which appeared unrelated, however, to the incidence of abstinence, or the manner of drug intake. Compared to the healthy control group, the test cases showed an increase of liver enzymes (Gamma-GT, SGOT, SGPT and LDH) but there was no marked difference between the 3 user categories themselves. The pathological neuroendocrine findings identified in test patients after a long period of abstinence are indicative of changes possibly based on genetic disposition rather than on abusive habits. The issue of self-inflicted damage, therefore, becomes a questionable one.
