Twenty-Eight-Day-Long Delirium Tremens.

Refractory alcohol withdrawal delirium is uncommon in day-to-day clinical practice. This case report presents a rare case of delirium tremens of unusually long duration that was complicated by the difficulty in tapering down benzodiazepines despite adding midazolam drip as well as phenobarbitone to the management regimen and excluding other possible diagnoses.

Barbiturates for the treatment of alcohol withdrawal syndrome: A systematic review of clinical trials.

PURPOSE: To perform a systematic review of the clinical trials concerning the use of barbiturates for the treatment of acute alcohol withdrawal syndrome (AWS). MATERIALS AND METHODS: A literature search of MEDLINE, EMBASE, and the Cochrane Library, together with a manual citation review was conducted. We selected English-language clinical trials (controlled and observational studies) evaluating the efficacy and safety of barbiturates compared with benzodiazepine (BZD) therapy for the treatment of AWS in the acute care setting. Data extracted from the included trials were duration of delirium, number of seizures, length of intensive care unit and hospital stay, cumulated doses of barbiturates and BZDs, and respiratory or cardiac complications. RESULTS: Seven studies consisting of 4 prospective controlled and 3 retrospective trials were identified. Results from all the included studies suggest that barbiturates alone or in combination with BZDs are at least as effective as BZDs in the treatment of AWS. Furthermore, barbiturates appear to have acceptable tolerability and safety profiles, which were similar to those of BZDs in patients with AWS. CONCLUSIONS: Although the evidence is limited, based on our findings, adding phenobarbital to a BZD-based regimen is a reasonable option, particularly in patients with BZD-refractory AWS.

Impact of adaptive functioning on readmission to alcohol detoxification among Alaska Native People.

BACKGROUND: This study examined predictors associated with readmission to detoxification in a sample of adult Alaska Native patients admitted to inpatient alcohol detoxification. Even though Alaska Native people diagnosed with alcoholism have been identified as frequent utilizers of the health care system and at elevated risk of death, little is known about factors associated with readmission to detoxification for this group. METHODS: We sought to predict readmission using a retrospective cohort study. The sample included 383 adult Alaska Native patients admitted to an inpatient detoxification unit and diagnosed with alcohol withdrawal during 2006 and 2007. Cox proportional hazard modeling was used to estimate unadjusted and adjusted associations with time to readmission within one year. RESULTS: Forty-two percent of the patients were readmitted within one year. Global Assessment Functioning (GAF; Axis V in the multi-axial diagnostic system of the Diagnostic and Statistical Manual of Mental Disorders [DSM IV]) score measured at the time of intake was associated with readmission. A one point increase in the GAF score (HR=.96, 95% CL=.94, .99, P=.002) was associated with a four percent decrease in readmission. The results also indicated that the GAF mediated the relationship between readmission and: employment and housing status. CONCLUSIONS: The GAF measures both illness severity and adaptive functioning, is part of standard behavioral health assessments, and is easy to score. Readmission rates potentially could be decreased by creating clinical protocols that account for differences in adaptive functioning and illness severity during detoxification treatment and aftercare.

[Unusual alcoholic weaning, complicated: do you check the blood phosphate?]. / Sevrage éthylique inhabituel et compliqué: avez-vous vérifié la phosphatémie?

A 65 year old alcoholic man was hospitalized because he was tired, hypotonic, with postural tremor. The neurologic symptoms increased during the first two days despite an adequate therapy for alcoholic weaning with hydratation, benzodiazepines and vitamins. A severe hypophosphatemia is diagnosed, associated with hypovitaminosis D, mild hypomagnesemia, mild hypokaliemia and a refeeding syndrome. 24 hours after the normalisation of his phosphatemia, the neurologic symptoms are adjusted.

Alcohol withdrawal syndrome.

In susceptible patients, alcohol withdrawal syndrome (AWS) is often precipitated by other medical or surgical disorders, and AWS can adversely affect the course of these underlying conditions. Although the mortality rate of AWS has decreased over the past few decades, significant risk for morbidity and death remain if management is complicated by a variety of conditions. This review of AWS focuses on the scope of the clinical problem, historical features, pathophysiology, clinical presentation, and approaches to therapy, with particular emphasis on severe AWS that requires management in the intensive care unit.

[Treatment of alcohol withdrawal symptoms]. / Alkoholivieroitusoireiden hoito.

In the summer, alcohol consumption increases and the number of those requiring rehabilitation peaks at the end of the holiday season. Treatment of alcohol withdrawal symptoms early enough helps the patient to break the drinking cycle. Treatment of alcohol withdrawal symptoms will also prevent complications, such as convulsions and alcoholic delirium. Untreated alcoholic delirium is a life-threatening condition. Treatment aims to calm down the hyperactivity state of the autonomous nervous system, and correct electrolyte and fluid balance disturbances. Initiation of rehabilitation is determined by the severity of the patient's withdrawal symptoms. Benzodiazepines are the first-line drugs.

[Levels of emotional awareness in alcohol-dependent patients and abstinent alcoholics]. / Niveaux de conscience émotionnelle chez les sujets alcoolodépendants et abstinents.

BACKGROUND: Deficits in the communication and identifying of feelings are usually observed in addiction disorders. These dysfunctions vary according to the type of addiction and are particularly marked for alcoholic subjects. The prevalence of alexithymia evolves in a nearly linear manner according to the severity and the duration of the disorder. As the duration of alcoholism and the quantity of alcohol that is consumed increase, so will the subjects' scores of alexithymia. In addition, certain authors have observed a decrease in alexithymia in abstinent subjects. Subjects having been abstinent for a long period of time were more alexithymic than those having been abstinent for a shorter period of time. However, other studies failed to confirm these findings and did not observe an increase in the levels of alexithymia in polydrug patients. It seems however that the measures of alexithymia obtained using self evaluation tools (TAS 20) lack in precision due to the fact that, even though the subject is supposed to have a deficit in the identifying and the verbalisation of his emotional states, he is asked to do his own evaluation of the said emotional states. Hence, other tools such as the level of emotional awareness scale (LEAS) offer another approach to the measuring of alexithymia, based on the everyday situations and integrated in a general model of the differentiation of emotional states (or of emotional awareness). DESIGN OF STUDY: The purpose of the study is to describe the level of emotional differentiation of alcoholic subjects, and to evaluate the development of the emotional processes following alcohol cessation. Our sample consists of 88 subjects distributed in three groups: a group of alcoholic participants who are in the process of quitting alcohol (33 subjects), a group of alcoholic participants that have been abstinent for more than 6 months (20 subjects) and a group of control participants (35 subjects). The prevalence of alexithymia is estimated by the Toronto alexithymia scale (TAS 20) which measures three factors: the difficulty to identify one's feelings (TAS 1), the difficulty to express one's feelings (TAS 2), and thoughts which are directed towards the outside world (TAS 3). The levels of emotional consciousness are estimated by the LEAS which establishes 20 scenarios in order to measure three scores: emotional consciousness "for oneself" (LEAS 1), emotional consciousness "for others" (LEAS 2) and a total score (total LEAS). RESULTS: The results show a different level of emotional awareness and alexithymia between the three groups of participants. The alcoholic participants are less conscious of their feelings and have more difficulties identifying and expressing their feelings than the control subjects. With regards to the evolution of the emotional deficit linked to alcohol withdrawal, the abstinent subjects obtain weaker scores of alexithymia than the alcoholic subjects. However, abstinent subjects continue to present more difficulties expressing their feelings than control subjects (TAS 2). On the other hand, abstinent subjects' levels of emotional awareness are once again comparable to those of control subjects. Finally, the analysis of the correlations does not show any link between the scores of alexithymia and the scores of emotional consciousness, and this for all of the groups studied. Our major result concerns the recovery of the emotional deficit of abstinent subjects (global score of TAS 20 and the score of emotional consciousness), which underlines the importance of the implementation of therapeutic protocols that focus on the emotional awareness of alcoholic subjects.

[Diagnostics and therapy of alcohol withdrawal syndrome: focus on delirium tremens and withdrawal seizure]. / Diagnostik und Therapie des Alkoholentzugssyndroms: Fokus auf Delirium tremens und Entzugskrampfanfall.

INTRODUCTION: Delirium tremens and withdrawal seizures are serious complications of an alcohol withdrawal syndrome. This review presents the diagnostic procedures required in case of the occurrence of a withdrawal seizure and delirium tremens as well as possible treatment options including prophylactic medication regimen for alcohol withdrawal syndrome. Furthermore non-pharmacological procedures accompanying delirium tremens and a potential integration of viewing videotapes of delirium tremens in the course of alcohol-specific therapy are discussed. METHODS: A systematic literature research using Pubmed has been carried out to find recent studies and review articles dealing with alcohol withdrawal syndrome. RESULTS AND DISCUSSION: Regarding the diagnostic algorithm in case of the occurrence of a withdrawal seizure or a delirium tremens basic diagnostic procedures and special diagnostics including neuro-imaging or cerebrospinal fluid puncture depending on patients' clinical condition have to be considered. Sedatives are important in treatment of alcohol withdrawal seizures and delirium tremens as well as in the prophylaxis of alcohol withdrawal syndrome. A long-lasting prescription of anticonvulsant medication in patients suffering from withdrawal seizure should be considered critically and can be carried out only under certain conditions.

Genome-wide association study of alcohol dependence.

CONTEXT: Alcohol dependence is a serious and common public health problem. It is well established that genetic factors play a major role in the development of this disorder. Identification of genes that contribute to alcohol dependence will improve our understanding of the mechanisms that underlie this disorder. OBJECTIVE: To identify susceptibility genes for alcohol dependence through a genome-wide association study (GWAS) and a follow-up study in a population of German male inpatients with an early age at onset. DESIGN: The GWAS tested 524,396 single-nucleotide polymorphisms (SNPs). All SNPs with P < 10(-4) were subjected to the follow-up study. In addition, nominally significant SNPs from genes that had also shown expression changes in rat brains after long-term alcohol consumption were selected for the follow-up step. SETTING: Five university hospitals in southern and central Germany. PARTICIPANTS: The GWAS included 487 male inpatients with alcohol dependence as defined by the DSM-IV and an age at onset younger than 28 years and 1358 population-based control individuals. The follow-up study included 1024 male inpatients and 996 age-matched male controls. All the participants were of German descent. MAIN OUTCOME MEASURES: Significant association findings in the GWAS and follow-up study with the same alleles. RESULTS: The GWAS produced 121 SNPs with nominal P < 10(-4). These, together with 19 additional SNPs from homologues of rat genes showing differential expression, were genotyped in the follow-up sample. Fifteen SNPs showed significant association with the same allele as in the GWAS. In the combined analysis, 2 closely linked intergenic SNPs met genome-wide significance (rs7590720, P = 9.72 x 10(-9); rs1344694, P = 1.69 x 10(-8)). They are located on chromosome region 2q35, which has been implicated in linkage studies for alcohol phenotypes. Nine SNPs were located in genes, including the CDH13 and ADH1C genes, that have been reported to be associated with alcohol dependence. CONCLUSIONS: This is the first GWAS and follow-up study to identify a genome-wide significant association in alcohol dependence. Further independent studies are required to confirm these findings.

Changes in general nurses' knowledge of alcohol and substance use and misuse after education.

PURPOSE: This study aims to assess the impact of an education program on Australian general nurses' knowledge and competence in identifying and managing patients with alcohol and substance use and misuse, and compare findings with existing literature on mental health nurses. DESIGN AND METHODS: Pre- and posttest design without a control group. FINDINGS: The nurses' knowledge of safe drinking limits and alcohol withdrawal management improved following the education. Nevertheless, overall the nurses reported a lack of adequate knowledge and competence. Compared to mental health nurses, the nurses in this study had lower levels of knowledge and competence. PRACTICE IMPLICATIONS: We suggest several opportunities for general nurses to strengthen their knowledge and skills and the need for a comprehensive and regular education program.

Alcohol-use disorders.

Alcohol dependence and alcohol abuse or harmful use cause substantial morbidity and mortality. Alcohol-use disorders are associated with depressive episodes, severe anxiety, insomnia, suicide, and abuse of other drugs. Continued heavy alcohol use also shortens the onset of heart disease, stroke, cancers, and liver cirrhosis, by affecting the cardiovascular, gastrointestinal, and immune systems. Heavy drinking can also cause mild anterograde amnesias, temporary cognitive deficits, sleep problems, and peripheral neuropathy; cause gastrointestinal problems; decrease bone density and production of blood cells; and cause fetal alcohol syndrome. Alcohol-use disorders complicate assessment and treatment of other medical and psychiatric problems. Standard criteria for alcohol dependence-the more severe disorder-can be used to reliably identify people for whom drinking causes major physiological consequences and persistent impairment of quality of life and ability to function. Clinicians should routinely screen for alcohol disorders, using clinical interviews, questionnaires, blood tests, or a combination of these methods. Causes include environmental factors and specific genes that affect the risk of alcohol-use disorders, including genes for enzymes that metabolise alcohol, such as alcohol dehydrogenase and aldehyde dehydrogenase; those associated with disinhibition; and those that confer a low sensitivity to alcohol. Treatment can include motivational interviewing to help people to evaluate their situations, brief interventions to facilitate more healthy behaviours, detoxification to address withdrawal symptoms, cognitive-behavioural therapies to avoid relapses, and judicious use of drugs to diminish cravings or discourage relapses.

Proof-of-concept human laboratory study for protracted abstinence in alcohol dependence: effects of gabapentin.

There is a need for safe medications that can effectively support recovery by treating symptoms of protracted abstinence that may precipitate relapse in alcoholics, e.g. craving and disturbances in sleep and mood. This proof-of-concept study reports on the effectiveness of gabapentin 1200 mg for attenuating these symptoms in a non-treatment-seeking sample of cue-reactive, alcohol-dependent individuals. Subjects were 33 paid volunteers with current Diagnostic and Statistical Manual of Mental Disorders-IV alcohol dependence and a strength of craving rating 1 SD or greater for alcohol than water cues. Subjects were randomly assigned to gabapentin or placebo for 1 week and then participated in a within-subjects trial where each was exposed to standardized sets of pleasant, neutral and unpleasant visual stimuli followed by alcohol or water cues. Gabapentin was associated with significantly greater reductions than placebo on several measures of subjective craving for alcohol as well as for affectively evoked craving. Gabapentin was also associated with significant improvement on several measures of sleep quality. Side effects were minimal, and gabapentin effects were not found to resemble any major classes of abused drugs. Results suggest that gabapentin may be effective for treating the protracted abstinence phase in alcohol dependence and that a randomized clinical trial would be an appropriate next step. The study also suggests the value of cue-reactivity studies as proof-of-concept screens for potential antirelapse drugs.

Improved outcomes in patients with head and neck cancer using a standardized care protocol for postoperative alcohol withdrawal.

OBJECTIVE: To show clinical benefit in the main outcome measures by the use of a standardized protocol for identification, characterization, and treatment of alcohol withdrawal syndrome (AWS) in postoperative patients with head and neck cancer. DESIGN: Prospective cohort study with a retrospective cohort control. SETTING: Tertiary care university. PATIENTS: A total of 26 consecutive postoperative patients with AWS were selected from among 652 patients with head and neck cancer to be enrolled in the protocol from March 2003 through March 2005. Controls consisted of 14 of 981 consecutive patients with AWS from March 2000 through December 2002. INTERVENTION: Application of a standardized care protocol. MAIN OUTCOME MEASURES: Sensitivity and specificity of preoperative screening for AWS risk, predictability of outcomes, length of stay, transfers to the intensive care unit (ICU), AWS symptoms, postoperative morbidity and mortality, doses of pharmacotherapy required, and charges. RESULTS: Protocol patients demonstrated significantly fewer AWS-related ICU transfers and less delirium and violence than preprotocol patients. Mortality, wound complications, hospital charges, and doses of benzodiazepines, clonidine, and haloperidol were not significantly different between these 2 groups. Preoperative medical history correlated poorly with AWS outcomes. Screening was 87.5% sensitive and 99.7% specific. Late enrollees to the protocol (false-negative screening results) showed many significantly worse outcomes than immediate enrollees. CONCLUSION: Use of the standardized AWS symptom-triggered protocol decreased delirium, violence, and AWS-related ICU transfers without significantly increasing hospital charges.

Phosphatidylethanol as a sensitive and specific biomarker: comparison with gamma-glutamyl transpeptidase, mean corpuscular volume and carbohydrate-deficient transferrin.

Phosphatidylethanol (PEth), a direct ethanol metabolite, is detectable in blood for more than 2 weeks after sustained ethanol intake. Our aim was to assess the usefulness of PEth [comparing sensitivity, specificity and the area under the curve (AUC)] as compared with carbohydrate-deficient transferrin (CDT), gamma-glutamyl transpeptidase (GGT) and mean corpuscular volume (MCV), calculating the results from sober patients against those from alcohol-dependent patients during withdrawal. Fifty-six alcohol-dependent patients (ICD-10 F 10.25) in detoxification, age 43 years, GGT 81 U/l, MCV 96.4 fl, %CDT 4.2, 1400 g ethanol intake in the last 7 days (median), were included in the study. Over the time of 1 year, 52 samples from 35 sober forensic psychiatric addicted in-patients [age 34 years, GGT 16 U/l, MCV 91 fl, CDT 0.5 (median)] in a closed ward were drawn and used for comparison . PEth was measured in heparinized whole blood with a high-performance liquid chromatography method. GGT, MCV and %CDT were measured using routine methods. A receiver operating characteristic curve analysis was carried out, with 'current drinking status' (sober/drinking) as the state variable and PEth, MCV, GGT and CDT as test variables. The resulting AUC was 0.974 (P < 0.0001, confidence interval 0.932-1.016) for PEth. At a cut-off of 0.36 micromol/l, the sensitivity was 94.5% and specificity 100%. The AUC for CDT, GGT and MCV were 0.931, 0.894 and 0.883, respectively. A significant Spearman's rank correlation was found between PEth and GGT (r = 0.739), CDT (r = 0.643), MVC (r = 0.639) and grams of ethanol consumed in the last 7 days (r = 0.802). Our data suggest that PEth has potential to be a sensitive and specific biomarker, having been found in previous studies to indicate longer lasting intake of higher amounts of alcohol.

A strategy of escalating doses of benzodiazepines and phenobarbital administration reduces the need for mechanical ventilation in delirium tremens.

OBJECTIVE: Patients with severe alcohol withdrawal and delirium tremens are frequently resistant to standard doses of benzodiazepines. Case reports suggest that these patients have a high incidence of requiring intensive care and many require mechanical ventilation. However, few data exist on treatment strategies and outcomes for these subjects in the medical intensive care unit (ICU). Our goal was a) to describe the outcomes of patients admitted to the medical ICU solely for treatment of severe alcohol withdrawal and b) to determine whether a strategy of escalating doses of benzodiazepines in combination with phenobarbital would improve outcomes. DESIGN: Retrospective cohort study. SETTING: Inner-city municipal hospital. PATIENTS: Subjects admitted to the medical ICU solely for the treatment of severe alcohol withdrawal. INTERVENTIONS: Institution of guidelines emphasizing escalating doses of diazepam in combination with phenobarbital. MEASUREMENTS AND MAIN RESULTS: Preguideline (n = 54) all subjects were treated with intermittent boluses of diazepam with an average total and maximal individual dose of 248 mg and 32 mg, respectively; 17% were treated with phenobarbital. Forty-seven percent required intubation due to inability to achieve adequate sedation and need for constant infusion of sedative-hypnotics. Intubated subjects had longer length of stay (5.6 vs. 3.4 days; p = .09) and higher incidence of nosocomial pneumonia (42 vs. 21% p = .08). Postguideline (n = 41) there were increases in maximum individual dose of diazepam (32 vs. 86 mg; p = .001), total amount of diazepam (248 vs. 562 mg; p = .001), and phenobarbital use (17 vs. 58%; p = .01). This was associated with a reduction in the need for mechanical ventilation (47 vs. 22%; p = .008), with trends toward reductions in ICU length of stay and nosocomial pneumonia. CONCLUSIONS: Patients admitted to a medical ICU solely for treatment of severe alcohol withdrawal have a high incidence of requiring mechanical ventilation. Guidelines emphasizing escalating bolus doses of diazepam, and barbiturates if necessary, significantly reduced the need for mechanical ventilation and showed trends toward reductions in ICU length of stay and nosocomial infections.

Risk factors for delirium tremens: a retrospective chart review.

A retrospective chart review was performed within an inpatient VA hospital setting in an attempt to identify risk factors for delirium tremens (DTs). Cases of delirium tremens were compared to cases where patients' alcohol withdrawal during hospitalization did not progress to DTs. Significant differences were found in regard to prior histories of DTs and laboratory values at admission. The amount and duration of benzodiazepine use during hospitalization, antipsychotic use during hospitalization, and length of hospitalization were also statistically different between the groups. While not reaching statistical significance, there were differences in reason for admission and relapse rate upon follow-up between the groups.

[Assessment of socio-demographic factors in alcohol-addicted patients recurrently treated in a detoxification unit]. / Ocena czynników socjodemograficznych u osób uzaleznionych od alkoholu wielokrotnie leczonych w oddziale detoksykacji.

The aim of the presented study was the assessment some socio-demographic factors of alcohol dependent patients more times hospitalized in Department of Toxicology in Kraków in the years 1999-2004. The repeatedly hospitalization of 334 patients (298 men and 36 women), aged from 17 to 71 years (mean 45.1 years) due the alcohol problem on the basis of clinic documentation were established. The following socio-demographics traits were taken in analysis: age, sex, marital status, place of living, education, kind of jobs, employment and others sources of money. The patients were admitted from 2 or more 29 times during 6 years. Medical history of addiction of mentioned patients was from 1 to 40 years, mean 25 years. 43.7% persons live single and 53.6% was married. The most patients live in Kraków (80%) and others near the town. The education of them: 15.0% ended high school, 28.7% "medium", 30.5% "low professional" and elementary school--13.8% of them. This factor was similar like regional data. Amount mentioned persons 25.8% worked for salary, 11.7% had own business, and 25.4% was retired, and 29.0% was unemployed. This last factor was worse liked similar from mentioned region. The kind of jobs of persons on the aspect of "social safety" was described. Among the mentioned chronic alcohol addicted persons about 18.8% of them with machines in traffic was worked (bus drivers i.e.) and 7.5% described persons in special jobs was worked (policemen, physician i.e.). The authors were suggested that mentioned factors due health services cost in Poland and propose integration of treatment of alcohol-addicted patients.

[Outpatient alcohol withdrawal]. / Der ambulante Alkoholentzug.

Indications and contraindications for an alcohol withdrawal treatment of outpatients are presented, with particular reference to the symptoms and the diagnosis of the withdrawal syndrome. The general conditions and the practical process of outpatient detoxification are outlined. At the same time the question of medication of the withdrawal syndrome is addressed.
