RESUMEN
OBJECTIVES: Given the high prevalence of fast-metabolizing alcohol dehydrogenase-1B*2 (ADH1B*2 ) and inactive aldehyde dehydrogenase-2*2 (ALDH2*2 ) alleles in East Asians, we evaluated how the ADH1B / ALDH2 genotypes and alcohol flushing might affect the development of alcohol dependence (AD). METHODS: We evaluated how the ADH1B / ALDH2 genotypes and self-reported alcohol flushing affected history of drinking events and withdrawal symptoms and ICD-10 criteria in 4116 Japanese AD men. RESULTS: The ADH1B*1/*1 group and ALDH2*1/*1 group were 1-5 years younger than the ADH1B*2 (+) and ALDH2*1/*2 groups, respectively, for all of the ages at onset of habitual drinking, blackouts, daytime drinking, uncontrolled drinking, withdrawal symptoms, and first treatment for AD, and the current age. Blackouts were more common in the ADH1B*1/*1 group and ALDH2*1/*1 group. Daytime drinking, uncontrolled drinking, and withdrawal symptoms, such as hand tremor, sweating, convulsions, and delirium tremens/hallucinations were more common in the ADH1B*1/*1 group. The ADH1B*1/*1 was positively associated with the ICD-10 criteria for 'tolerance' and 'withdrawal symptoms'. The ADH1B*1/*1 group and ALDH2*1/*2 group had a larger ICD-10 score. Never flushing was reported by 91.7% and 35.2% of the ALDH2*1/*1 and ALDH2*1/*2 carriers, respectively. After a 1-2-year delay in the onset of habitual drinking in the former-/current-flushing group, no differences in the ages of the aforementioned drinking milestones were found according to the flushing status. CONCLUSION: The ADH1B*1/*1 and ALDH2*1/*1 accelerated the development of drinking events and withdrawal symptoms in Japanese AD patients. ICD-10 score was larger in the ADH1B*1/*1 group and ALDH2*1/*2 group. The effects of alcohol flushing on drinking events were limited.

BACKGROUND: While accumulating evidence suggests a relation between the severity of alcohol dependence and the risk of its recurrence, the impact of dependence severity on the course of the disorder has not been carefully evaluated. The present study examined the impact of several severity indices of alcohol dependence on the drinking course after inpatient treatment. METHODS: This prospective study was conducted over a 12-month period following alcohol treatment at a specialized hospital. A total of 712 consecutively admitted alcohol-dependent patients were targeted for enrollment at the time of their hospitalization, with 637 patients registered and followed. The characteristics and severity of the subjects were assessed using multiple methods at admission, with their course after discharge followed continuously using mailed questionnaires that queried them regarding their drinking behavior. RESULTS: Greater severity of dependence, assessed using the number of ICD-10 diagnostic criteria met, was associated with a lower rate of abstinence during the study period (p = 0.035). The rate of abstinence also decreased significantly as the baseline blood gamma-glutamyl transferase value and Alcohol Dependence Scale (ADS) score increased (p = 0.031 and p = 0.0002, respectively). In multivariate Cox proportional hazards analyses, the group with the most severe ADS scores had a significantly greater risk of relapse to drinking than the group with the least severe scores (HR = 2.67, p = 0.001). Dependence severity also associated with the drinking pattern; participants in both the controlled drinking group and the abstinence group had lower ADS scores at admission and a later age at first drinking (p = 0.001 and p < 0.001, respectively) than those with poorer drinking outcomes. CONCLUSIONS: The present study showed that more severe alcohol dependence predicts a poorer course after alcohol treatment, as reflected by findings on multiple measures. These results suggest that assessing the dependence severity at the outset of treatment could be useful both in predicting treatment outcome and targeting interventions to alcohol-dependent individuals who need additional support in their recovery.

BACKGROUND: In this study, we aim to estimate the prevalence of heated tobacco product (HTP) smokers 3 years after the launch of HTPs in Japan. METHODS: Our study, performed in February 2018 in Japan, had a cross-sectional population-based design. A total of 4,628 adult participants (2,121 men and 2,507 women) were randomly sampled from all regions of Japan. The response rate was 57.9%. Interviews were conducted by trained investigators who visited participants' homes. A survey on current (past 30 days) and lifetime tobacco use (including e-cigarettes and HTPs), as well as numerous sociodemographic factors, was conducted. RESULTS: The age-adjusted rates and estimated number of lifetime-HTP smokers were 14.1% (95% confidence interval [CI], 12.5-15.6%; 7.11 million men) and 3.7% (95% CI, 2.9-4.4%; 1.99 million women). The age-adjusted rates for current HTP smokers were 8.3% (95% CI, 7.1-9.6%; 4.21 million men) and 1.9% (95% CI, 1.3-2.4%; 1.02 million women). Multiple variables were found to be associated with a higher prevalence of current HTP use, including being male, aged 20-39 years, a current Internet user, a risky drinker, or a heavy episodic drinker. HTP use was also higher among men with 10 years or more of education, women with 15 years or less of education, and men with middle- or high-level household incomes. CONCLUSION: We concluded that HTP use has increased substantially in Japan. However, regulations for HTPs are weaker than those for combustible cigarettes in Japan. Thus, HTPs should be subjected to the same regulations as combustible tobacco products.

Coping skills training (CST) and cue exposure treatment (CET) have yielded favorable outcomes when used to treat alcoholics. We conducted 6-week inpatient programs that consisted of 9 CST group sessions (n = 117) during 2005-2009 and 9 CST group sessions plus 4 CET group sessions (n = 49) during 2009-2011 and subsequent 1-year letter therapy for Japanese alcoholic men who had relapsed and been readmitted after standard cognitive-behavioral inpatient therapy. When patients received a letter containing encouraging words every 2 weeks, they were asked to reread their CST and CET records and to respond to the letter by marking drinking days on a calendar and naming the skills on a list of the 9 CST themes and CET that were useful for maintaining abstinence during that 2-week period. The estimated percentages of achievement of 30 or fewer drinking days during the one year of letter therapy were 36.1 - 45.8%. 'Non-smoking', '2nd admission', and 'After age-limit job retirement' were significant factors in achieving good outcomes. The 'usefulness' responses for 'Increasing pleasant activities', 'CET', 'Anger management', ' Managing negative thinking', 'Problem solving', and ' Seemingly irrelevant decisions' as percentages of overall responses to the letters were significantly higher, in order of decreasing percentages, in the achiever group than in the non-achiever group, but the differences between the groups in ' Managing urges to drink', ' Drink refusal skills', ' Planning for emergencies', and ' Receiving criticism about drinking' were not significant. The odds ratios for achievement of 30 or fewer drinking days during the 1-year period increased significantly by 1.15 -1.31 fold per 10% increment in the 'usefulness' ratio for 'Increasing pleasant activities'. The difference in percentage achievement between the group treated by CST alone and the group treated by CST plus CET was not significant. In conclusion, some coping skills were more useful for relapse prevention than others in this study population, and addition of CET to CST and subsequent letter therapy did not improve outcomes.

Alcoholics have a high prevalence of nicotine dependence, and smoking is a major contributor to their high mortality. Three weeks after admission to an addiction center in Japan, 193 alcoholic men who were participating in an 11-week concurrent inpatient smoking cessation and alcohol abstinence programs filled out an anonymous self-report questionnaire regarding smoking and drinking, and 6 months after the completion of the programs, 83 patients were asked to respond to a mailed questionnaire about their smoking and drinking status. Of the 193 subjects, 73.3% were current smokers, but many were highly motivated in regard to both smoking cessation and alcohol abstinence. The subjects' scores on a 0 to 10 point scale for rating motivation and confidence in regard to smoking cessation and smoking urge were significantly correlated with each other and with their scores for motivation and confidence in regard to alcohol abstinence and drinking urge. Three weeks after admission, varenicline treatment was well-tolerated, and the varenicline group had a high rate of smoking cessation than the smoker group not treated with varenicline (67.7% vs. 44.6%, p = 0.012). Forty-six (55.4%) of the 83 subjects who were mailed the questionnaire responded, and the drinking category was 'totally abstinent' in 35 subjects (42.2%), and 'mostly abstinent' in another 4 subjects (4.8%). Seventeen (20.5%) of the 83 subjects were non-smokers before treatment, but after treatment, 23 (50.0%) of the 46 responders and 20 (51.3%) of the 'totally or mostly abstinent' 39 responders were total or almost non-smokers. The response rate of 'totally or mostly abstinent' was higher among the 17 non-smokers before treatment than among the 66 smokers before treatment (70.6% vs. 40.9%, p = 0.033), and the age-adjusted odds ratio (95% confidence interval) for the response of 'totally or mostly abstinent' was 3.30 (1.03-10.56) for the non-smokers before treatment (vs. the smokers before treatment). In conclusion, smoking status had a great impact on the drinking status of treatment-seeking alcoholic men, and smoking cessation should be recommended to smoking alcoholics.

We conducted a survey of alcohol-dependent patients at the time of their first visit and physicians in regard to the goals of treatment of alcohol dependence. There were 99 replies from patients, and replies from physicians related to 64 of the patients' replies were also received, and in 25.0% of them it was judged possible to make reducing the amount of alcohol consumed a temporary or final goal. Having a mild drinking problem, the absence of a personality disorder or mental retardation, the presence of a strong motivation in regard to treatment, etc., were cited as reasons for the physicians' judgments. In addition, the number of diagnostic criteria of the ICD-10 for dependence syndrome that applied was shown to be significantly related to the judgments regarding treatment goals. However, as for Alcohol Dependence Scale (ADS), there was no significant relationship with the treatment goal.

BACKGROUND: Growing evidence suggests that intervention for smoking cessation enhances alcohol abstinence in treatment settings for alcohol dependence. However, research in this field is rare in Asians. METHOD: We prospectively investigated the association of smoking status with drinking status using 9 surveys mailed during a 12-month period in 198 Japanese alcohol-dependent men (70 never/ex-smokers and 128 smokers) who admitted for the first time and completed a 3-month inpatient program for simultaneous alcohol abstinence and smoking cessation. RESULTS: Nonsmoking during the first month after discharge and at the end of follow-up was reported in 28.9% and 25.0% of the baseline smokers, respectively. Kaplan-Meier estimates showed that a 12-month alcohol abstinence and heavy-drinking-free status were more frequent among never/ex-smokers (45.1% and 59.8%, respectively) and baseline smokers who quit smoking during the first month after discharge (59.0% and 60.8%, respectively), compared with sustained smokers (30.0% and 41.2%, respectively). Among the baseline smokers, the multivariate odds ratio (95% confidence interval) for smoking cessation during the first month were 2.77 (1.01-7.61) for alcohol abstinence during the period and 2.50 (1.00-6.25) for use of varenicline, a smoking cessation agent, during the inpatient program. After adjusting for age, drinking profile, lifestyle, family history of heavy or problem drinking, lifetime episodes of other major psychiatric disorders, and medications at discharge, the multivariate hazard ratios (HRs) for drinking lapse were 0.57 (0.37-0.89) for the never/ex-smoking and 0.41 (0.23-0.75) for new smoking cessation groups, respectively, compared with sustained smoking, while the corresponding HRs for heavy-drinking lapse were 0.55 (0.33-0.90) and 0.47 (0.25-0.88), respectively. The HR for drinking lapse was 0.63 (0.42-0.95) for the nonsmoking group (vs. smoking) during the observation period, while the HR for heavy-drinking lapse was 0.58 (0.37-0.91) for the nonsmoking group (vs. smoking) during the observation period. Other significant variables that worsened drinking outcomes were higher daily alcohol intake prior to hospitalization, family history of heavy or problem drinking and psychiatric medications at discharge. CONCLUSION: Nonsmoking was associated with better outcomes on the drinking status of Japanese alcohol-dependent men, and a smoking cessation program may be recommended to be integrated into alcohol abstinence programs.

The Inventory of Depressive Symptomatology, clinician version (IDSC), was developed by Rush et al. to evaluate the severity of major depressive episodes. The aim of the present study was to establish the interrater reliability of the Japanese version of the IDSC. A total of 16 subjects with DSMIV major depressive episode were evaluated. Two psychiatrists, who had completed a training session for evaluating the IDSC before starting this reliability study, attended systematic interview sessions with each subject to evaluate the IDSC independently, using the Japanese version of the structured interview guide for combined rating of the IDSC and the Hamilton Depression Rating Scale. The severity of the 30 IDSC items assessed by the two raters ranged from 0 to 4 for 27 items and from 0 to 3 for 3 items. The analysis of variance intraclass correlation interrater reliability values for the individual scale items ranged from 0.874 to 1.000. The present results suggest that the Japanese version of the IDSC is a potentially useful rating instrument with high interrater reliability for measuring the severity of depressive symptoms in the hands of psychiatrists with sufficient evaluation training.

BACKGROUND: The presence of large or multiple esophageal distinct iodine-unstained lesions (DIULs) is a strong predictor of field cancerization in the upper aerodigestive tract. Several risk factors for DIULs, including genetic polymorphisms of alcohol and aldehyde dehydrogenases (ADH1B, rs1229984; ALDH2, rs671), have been demonstrated in Japanese alcohol-dependent men. However, few evaluations of alcohol-dependent women have been conducted in this field. METHODS: Using multiple logistic regression models, we investigated the results of screening using esophageal iodine staining and the identification of determinants for esophageal DIULs in 472 Japanese alcohol-dependent women. RESULTS: DIULs ≥5 mm, multiple DILUs, and both characteristics were observed in 35 (7.4%), 31 (6.6%), and 16 (3.4%) patients, respectively. DIULs ≥5 mm were histologically diagnosed as low-grade intraepithelial neoplasia in 26 patients and superficial squamous cell carcinoma in 9 patients. Although the inactive heterozygous ALDH2*1/*2 genotype was more common (33.3% vs. 11.4%, p = 0.002) in the group with DIULs ≥5 mm than in the group without DIULs ≥5 mm, no significant differences in the results of a questionnaire asking about current and past facial flushing after a glass of beer were seen between the groups with and without DIULs ≥5 mm. When individuals with current or former flushing were assumed to have inactive ALDH2, the sensitivity and specificity of current or former flushing to identify the presence of inactive ALDH2 were 50.0% and 93.5%, respectively; these values were previously reported to be 88% and 92%, respectively, in a Japanese general female population. The low sensitivity in the present study suggests that a lack of alcohol flushing may play a crucial role in the development of alcohol dependence in women with inactive ALDH2. No significant differences in age, usual alcohol consumption, or smoking habits were observed according to ADH1B and ALDH2 genotypes. Multiple logistic regression analyses showed that the slow-metabolizing ADH1B*1/*1 genotype (odds ratio [95% confidence interval], 12.5 [4.82-32.4] and 9.89 [3.50-27.9]), the inactive heterozygous ALDH2*1/*2 genotype (2.94 [1.18-7.38] and 3.79 [1.40-10.3]), a lower body mass index per -1 kg/m2 (1.17 [1.02-1.35] and 1.38 [1.14-1.67]), and a mean corpuscular volume ≥106 fl (3.70 [1.56-8.81] and 3.27 [1.24-8.64]) increased the risk of DIULs ≥5 mm and multiple DIULs, respectively. The combination of ADH1B*1/*1 and ALDH2*1/*2 markedly increased the risk of esophageal DIULs ≥5 mm (39.3 [10.6-146]). CONCLUSIONS: Japanese alcohol-dependent women shared several common risk factors for esophageal squamous cell neoplasia with alcohol-dependent men, but with considerably different magnitudes.
