Comorbid psychiatric diagnosis and long-term drinking outcome.

This longitudinal study of alcoholics investigated which psychiatric comorbidities among alcoholics would predict very long-term drinking outcome. Previous research has yielded inconsistent findings. We hypothesized that antisocial personality characteristics alone among psychiatric comorbidities would show an association with poorer drinking outcome. The use of multiple measures of psychopathology, a relatively large sample size, and an absence of systematic treatment matching to particular patient groups were all aspects of the current study which allowed for a comprehensive examination of this issue. The study used single and multivariate correlational analyses. The setting was an inpatient Veterans Administration alcohol dependence treatment unit and follow-up clinic. Participants were 255 adult male veterans diagnosed with alcohol dependence. The predictors were the Symptom Checklist 90 (SCL), Minnesota Multiphasic Personality Inventory (MMPI), and Psychiatric Diagnostic Interview (PDI). The outcome measure was the Clinician Rating of Drinking Scale (CRDS). The study showed that antisocial personality characteristics alone were consistently associated with a worse long-term drinking outcome. However, despite the consistent presence of a statistical association between antisocial personality characteristics and a poorer long-term drinking outcome, the small size of the relationship is a very important issue which is discussed in detail.

Mortality in male alcoholics after ten to fourteen years.

OBJECTIVE: Alcoholics frequently die prematurely. The purpose of this study was to determine: (1) whether subjects in a sample of 360 male alcoholics, followed over a period of 10-14 years, died prematurely: (2) if so, from what causes; and (3) whether such deaths are predictable from characteristics present at initial assessment. METHOD: Subjects were male veterans (N = 360) with a diagnosis of alcoholism admitted to an inpatient substance abuse treatment program at the Kansas City Veterans Affairs (VA) Medical Center during 1980-1984 who consented to participate in intake evaluations and subsequent follow-ups at 1 year and 10-14 years later. Of the 357 (99.2%) men located at the 10-14 year follow-up, 96 (26.6%) were confirmed as deceased, 255 survivors agreed to be reassessed and 6 subjects refused reassessment. Information regarding cause of death was obtained from death certificates, VA records and other sources. RESULTS: At intake, the subsequently deceased men were older, had less education, lower psychosocial functioning, more medical problems and greater psychiatric severity. Their overall death rate was 2.5 times greater than that of a reference group of men. Men in the 35-44 year age group were 5.5 times as likely to die. A statistical model utilizing measures of alcohol dependence to predict mortality from intake to 10-14 year follow-up indicated that alcoholics who limited drinking were half as likely to die whereas those who engaged in morning drinking were 2.5 times more likely to die. CONCLUSIONS: Alcoholic men, especially those in the group aged 35 to 44 years, have a significantly higher risk of premature death than a reference group of men. Men who engaged in morning drinking and could not limit drinking appeared to be at higher risk of mortality 10 years later.

The comparative validity of eleven alcoholism typologies.

OBJECTIVE: This study directly compared the clinical validity of 11 empirically defined alcoholism typologies to determine whether some typologies are clinically more valid than others. METHOD: A sample of 360 hospitalized alcoholic men were extensively evaluated at entry into the study and again 1 year later. Twenty-three measures of clinical validity were employed; 15 were postdictive and 8 were predictive. Postdictive retrospective measures obtained at entry into the study included family history, age of onset and lifetime course characteristics associated with alcoholism severity, general psychopathology and psychosocial functioning. Predictive outcome measures drawn from information obtained during the 1-year follow-up included: abstinence, alcoholism severity and clinician ratings of outcome. The measures were subjected to various statistical analyses, including factor analysis. RESULTS: We found that all of the alcoholism typologies met at least 7 of the 23 a priori measures of clinical validity. The correlations between these conceptually and methodologically disparate typologies were often striking. Exploratory factor analysis, which explained 35% of the variance, suggested three possible underlying dimensions to account for the overlap among typologies: (1) age and its correlates, including age-of-alcoholism onset; (2) "pure" alcoholism versus psychiatrically heterogeneous alcoholism that encompassed antisocial personality disorder; and (3) current severity of psychiatric distress, impairment and dysfunction. CONCLUSIONS: No single method of subtyping alcoholics clearly emerged as superior. All demonstrated some degree of predictive and postdictive clinical validity. Most methods of subtyping correlated positively with each other at moderate, but typically significant, levels.

Prediction of drinking outcomes for male alcoholics after 10 to 14 years.

This study reports on the long-term outcomes of 360 men who were hospitalized for alcoholism during 1980 to 1984 and followed at 12 months and again 10 to 14 years later. At the 10/14-year follow-up, 96 (26.7%) men were confirmed as deceased; 255 (70.8%) men participated in the assessment/interview battery completed during baseline hospitalization. The battery consisted of psychosocial, alcohol-related, and psychiatric measures. Two distinct but highly correlated outcome measures were selected: a clinical rating scale and a factor score. Overall, predictors from baseline and 12-month follow-up included age at intake hospitalization, alcoholism severity, social stability, drinking days, and antisocial personality disorder. Approximately 37% of the assessed survivors were either totally abstinent or drinking nonabusively throughout the 10/14-year follow-up, whereas another 37% continued to drink abusively. Men who abstained or reduced alcohol intake reported better physical health at follow-up than those who continued to drink. Although our findings did not directly link alcoholism to death, they strongly indicate that chronic alcohol abuse may lead to premature death.

Efficacy of outpatient intensive treatment for drug abuse.

OBJECTIVE: Outpatient intensive treatment for drug and alcohol abuse has become an alternative approach to management of substance abuse. We evaluated the efficacy of an outpatient intensive treatment program for crack cocaine; and the impact of psychiatric diagnosis on outcome variables. METHOD: Subjects participating in an outpatient intensive treatment program underwent descriptive testing at entry and at six-month followup. Outcome variables included Addiction Severity Index composite scores and retention in treatment. RESULTS: Subjects demonstrated significant improvement in ASI scales, over time, with an interaction effect of time and scale. Minimal interaction of psychiatric diagnosis and outcome was found. CONCLUSION: Outpatient intensive treatment demonstrated efficacy in reduction of ASI composite scores. Comparison with standard outpatient treatment and inpatient treatment is needed.

Pharmacological treatment for antisocial personality disorder alcoholics: a preliminary study.

A short time ago, we reported that a subgroup of hospitalized alcoholic men with comorbid antisocial personality disorder (ASP) seemed to benefit significantly from antidepressant medication at the end of a 6-month period in a double-blind, random assignment, placebo-controlled study. In a reanalysis of those data, we divided the ASP alcoholic group (n = 29) into those who did (n = 15) and who did not (n = 14) also satisfy DSM-III-R criteria for an additional current mood and/or anxiety disorder and then compared the 6-month outcomes of these two smaller subgroups. Despite the small ns, the results for most drinking outcome measures indicated: (1) that ASP alcoholics with a current mood/anxiety disorder improved significantly more with pharmacological treatment, relative to placebo; and (2) that ASP alcoholics with no current mood/anxiety disorder failed to respond differentially to pharmacological treatment over the 6-month period. These findings suggest a possibly useful and inexpensive approach to the long-term management of a very difficult-to-treat subgroup of men substance abusers.

A double-blind, placebo-controlled study of nortriptyline and bromocriptine in male alcoholics subtyped by comorbid psychiatric disorders.

This double-blind, placebo-controlled, 6-month follow-up treatment study investigated the efficacy of bromocriptine and nortriptyline in attenuating drinking behavior and psychiatric symptoms in 216 male alcoholic patients subtyped by comorbid psychiatric disorder(s). Three well-defined subtypes were examined: alcoholism only, alcoholism + affective/anxiety disorder, and alcoholism + antisocial personality disorder. It was hypothesized that both medications would relieve negative affective symptoms associated with alcohol use and would be particularly effective for the affective/anxiety subgroup. Contrary to our predictions, the only significant effects found were with the antisocial personality disorder patients who were receiving nortriptyline. One interpretation of the results was that nortriptyline may have reduced impulsive drinking in the antisocial personality disorder subgroup by actions on serotonergic neurotransmission.

Classification of alcoholism with reference to comorbidity.

Classification of individuals with alcoholism is currently limited. The purpose of this analysis was to determine whether antisocial personality disorder and other primary psychiatric syndromes identified subgroups of alcoholics with differing characteristics. Alcoholic probands (n = 224) with alcoholism were divided into those with primary alcoholism (n = 128), antisocial alcoholism (n = 50), and secondary alcoholism (n = 46). These groups were evaluated with regard to alcohol-related symptoms and upon a variety of psychiatric signs and symptoms. The secondary alcoholism. The antisocial alcoholic and primary alcoholic groups demonstrated many similarities, but overall, the antisocial alcoholic group appeared most severe. The antisocial alcoholic group additionally exhibited a dissociation between the subjectively reported and the observed behavior. These findings support the concept of heterogeneity within the alcoholism spectrum. Longitudinal data are needed to determine whether the observed cross-sectional differences predict outcome differences.

Impact of desipramine or carbamazepine on patient retention in outpatient cocaine treatment: preliminary findings.

This is a preliminary report of a double-blind comparison of desipramine or carbamazepine to placebo among subjects participating in an outpatient cocaine treatment program. Sixty-five subjects were randomly assigned to one of the active drugs or placebo and followed until treatment completion or drop-out to determine if either drug enhanced retention in treatment and/or increased cocaine abstinence. There was no significant difference between carbamazepine or desipramine and placebo on either outcome measure in this preliminary analysis. While this is a preliminary report and does not take into account the heterogeneity of the patients in cocaine treatment, the results are consistent with those of other investigators and suggest that use of desipramine or carbamazepine may not offer any advantage in retaining cocaine-dependent patients in treatment.

Outcomes of co-morbid alcoholic men: a 1-year follow-up.

In this prospective, 1-year study, 360 males admitted to an inpatient alcoholism treatment program were administered a DSM-III compatible structured interview and subtyped by co-occurring psychiatric disorder. Forty percent satisfied diagnostic criteria for alcohol dependence while 27% met criteria for alcohol dependence and one additional psychiatric syndrome. The dually diagnosed patients were divided into: alcohol dependence plus drug abuse, alcohol dependence plus antisocial personality and alcohol dependence plus depression. These subtypes were compared on multiple dimensions at intake and at 1-year follow-up. At follow-up, all groups showed significant improvement in drinking and psychosocial functioning. The results suggest that subtyping alcoholics by co-morbid psychiatric disorders may be a good postdictor of clinical history, but a poor predictor of drinking outcome.

A comparison of familial and nonfamilial male alcoholic patients without a coexisting psychiatric disorder.

Both family history of alcoholism and the presence of additional psychiatric disorder in male alcoholic patients are associated with an earlier onset of problem drinking, greater alcoholism severity and poorer clinical outcomes. To assess the relative contribution of family history alone, a sample of 212 male alcoholics not positive for any other psychiatric disorder was selected and divided into those with a family history of alcoholism (FH+) or no family history of alcoholism (FH-) among first degree relatives. Although FH+ alcoholics reported a younger age of onset of problem drinking and greater severity of some alcohol-related sequelae, the differences were not as extensive or pronounced as those found in a previous study of a sample of psychiatrically heterogeneous patients (Penick et al., 1987). A bi-dimensional typology of alcoholism incorporating both additional psychiatric diagnoses and a positive family history of alcoholism is suggested.

Examination of Cloninger's type I and type II alcoholism with a sample of men alcoholics in treatment.

Cloninger's clinical method of classifying alcoholics into two groups (Types I and II) was examined with data obtained from 360 VA hospitalized male alcoholic patients. For operational criteria, the Cloninger clinical method of subtyping alcoholics employs age-of-onset of problem drinking and symptom-clusters supposedly associated with each subtype. Marked overlap was found between the symptom-clusters used to define the two subtypes. Ninety-one percent of the entire sample satisfied criteria for both symptom-clusters. Dividing the sample by early-onset (Type II, less than or equal to 25 years) and late-onset (Type I, greater than 26 years) alcoholism did not substantially reduce the overlap between symptom-clusters; i.e., 96% of the early-onset and 83% of the late-onset subgroups were positive for both symptom-clusters. Only 21 men (6%) could be classified when both age-of-onset and the type-appropriate symptom-cluster were used to separate patients. In hospital settings, at least, these findings suggest that the two-group clinical alcoholism typology proposed by Cloninger basically reflects the age-of-onset of problem drinking.

Alcohol withdrawal in the elderly.

The phenomenon of alcohol withdrawal has seldom been studied in subgroups of patients in withdrawal. We developed a rating scale for measuring alcohol withdrawal that we found to be reliable and valid. The scale, when applied to young (ages 21-33, N = 24) and elderly (ages 58-77, N = 26) groups of patients in alcohol withdrawal, indicated that the elderly group initially had a more severe withdrawal for which they received higher doses of chlordiazepoxide.

The stability of coexisting psychiatric syndromes in alcoholic men after one year.

Alcoholic men (N = 241) were administered a criterion-referenced, structured, DSM-III compatible, diagnostic interview while hospitalized and again 1 year later as outpatients. This interview independently evaluates the lifetime prevalence of 15 major psychiatric disorders. In addition to alcoholism, the most frequently occurring coexisting disorders were depression, antisocial personality and drug abuse. After 1 year, the number of positive syndromes declined slightly (chi = 2.0 to 1.8). However, the absolute and relative number of additional psychiatric syndromes remained stable over 1 year for the entire sample. Across individuals, the overall rates of agreement for the 15 syndromes ranged from a high of 100% to a low of 85%. Similarly, the agreement for the current and lifetime diagnoses ranged from 86 to 99%. These data indicate that a substantial portion of male alcoholics experience symptoms that are common to other psychiatric disorders. They also suggest that the endorsement of multiple psychiatric symptoms is not due simply to the acute emotional and physical distress that often accompanies a recent hospitalization for alcoholism treatment. Instead, for many male alcoholics, the symptom patterns appear to reflect additional psychiatric disorders that are stable over time and a potential target of treatment.

Pharmacological treatment of alcohol intoxication, withdrawal and dependence: a critical review.

This review critically examines the literature of the past 10 years relating to the use of drugs in treating alcohol intoxication, withdrawal and dependence. Emphasis is given to those studies that have current and potential future clinical relevance. Although research regarding the pharmacological treatment of alcohol disorders still suffers from methodological flaws and lukewarm acceptance, the recognition of this area as a legitimate and fruitful field of study is increasingly apparent.

A comparative study of familial alcoholism.

In a large multicenter study of 568 male alcoholics, structured interviews were used to compare the clinical characteristics of patients with a positive (65%) or negative (35%) family history of abusive drinking among first degree relatives. Alcoholics with a positive family history were found to have: an earlier onset of alcoholism, greater alcoholic severity, more medical and legal problems, a broader range of treatments, an increased lifetime prevalence of additional psychiatric disorders and a greater diversity of psychiatric disturbance among biological relatives. The degree of psychiatric heterogeneity in the patients roughly corresponded to the degree of psychiatric heterogeneity in their families. Assortative mating was proposed as a possible mechanism to account for clinical differences between the familial and nonfamilial alcoholic.

Lithium compliance in alcoholic males: a six month followup study.

One hundred alcoholic patients were followed at monthly outpatient clinics for 6 months. Half were assigned low to moderate doses of lithium carbonate and half to chlordiazepoxide (10 mg tid) (active placebo). Drinking behavior and medication compliance were monitored at monthly clinics. After 6 months 52% of the lithium and 44% of the chlordiazepoxide patients were medication compliant. Of the 48% remaining in the lithium group, 14% did not return for a single visit while 14% came only once. Twenty percent came to clinic regularly; however they had never taken the medication as assigned. Of the 56% non-compliant chlordiazepoxide patients, 16% did not attend a single clinic; 24% came only once or twice and the remaining 16% attended clinics regularly although they were never medication-compliant. Drinking days and the percentage of patients reporting abstinence for one or more months were determined for medication compliant patients and for patients who attended clinic regularly but who did not take medication. Data were analyzed by Kruskal-Wallis one way analysis of variance tests. While lithium and chlordiazepoxide compliant patients tended to report fewer mean drinking days per month (4.6 and 4.8 respectively) than the non-medication group (6.9) these differences were not significant; however, compared to 44% in the non-medication group, 60% of the lithium patients and 58% of the chlordiazepoxide patients reported having significantly more months of abstinence (p less than .05). These results do not show that lithium is differentially efficacious in reducing alcohol consumption.

When alcoholics drink aftershave: a study of nonbeverage alcohol consumers.

A one-year prospective study was conducted to describe nonbeverage alcohol (NBA) consumption (the use of substitutes for traditional forms of ethanol) among alcoholics. It was found that 11% of inpatient alcoholics at a veterans' hospital and 8.6% of alcoholics at a community hospital had consumed NBA. Substances consumed ranged from toiletries to organic solvents, often in quantities exceeding the theoretical lethal dose. 'Ready availability' was cited as the primary reason for consumption. Social, demographic and psychiatric parameters were then compared between 48 VA alcoholics who used NBA and 48 nonusing alcoholics. No social or demographic differences were found, but NBA drinkers drank more alcohol (P less than 0.0001), had higher global alcoholic severity scores (P less than 0.0001), more severe withdrawal symptoms (P less than 0.0001), and a higher frequency of antisocial personality disorder (P = 0.009) and drug abuse (P = 0.005). When NBA drinkers were subdivided by quantity of NBA consumption and recency of latest ingestion, no social or psychological differences were found between groups, except for more frequent and heavier illicit drug use among 'heavy' NBA consumers (P less than 0.0001).

Alcoholics who drink mouthwash: the spectrum of nonbeverage alcohol use.

Nonbeverage alcohol (NBA), or substitutes for traditional forms of beverage alcohol, includes such substances as mouthwash, aftershave lotion and alcohol-based fuels. Literature pertaining to the prevalence, clinical significance and toxicity of this practice is reviewed, using illustrative cases from a series of 48 NBA consumers. It was found that 10-15% of alcoholics hospitalized in detoxication units have consumed NBA; half of these patients are regular consumers. Addiction to NBA itself may occur. Its use is primarily related to easy accessibility, rather than social or monetary factors. Polydrug misuse and antisocial personality disorder are more frequent in NBA users, but use is not pathognomic of end-stage alcoholism. The 48 NBA users reported surprisingly few toxic symptoms from acute ingestion, perhaps because tolerance to some substances in NBA may occur. Isopropyl alcohol was the exception, reproducibly causing symptoms suggestive of severe gastritis.
