4 At-risk Drinking Addiction Drinking How much is too much?
(Heavy drinking) Addiction (Alcohol Use Disorder) Neuroplastic changes Tolerance and Withdrawal Loss of Control Functional Impairment ≥ 4 drinks per day ≥ 14 drinks per week 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

5 Drinking At-risk Drinking Addiction Abstinence
Spectrum of Alcohol Drinking Drinking At-risk Drinking (Heavy drinking) Addiction (Alcohol Use Disorder) Abstinence Return to heavy drinking (Relapse) Return to drinking (Lapse, Temporary Slip) 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

6 Liver transplantation for alcoholic liver disease: current concepts and length of sobriety.
Lim and Keeffe. Liver Transpl Oct;10(10 Suppl 2):S31-8. How often do patients with alcoholic liver disease experience relapse following liver transplantation? Are there reliable ways to predict relapse in patients prior to liver transplantation? Are 6-month mandated abstinence requirements justified by the evidence? 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

Liver transplantation for alcoholic liver disease: current concepts and length of sobriety. Lim and Keeffe. Liver Transpl Oct;10(10 Suppl 2):S31-8. How often do patients with alcoholic liver disease experience relapse following liver transplantation? Are there reliable ways to predict relapse in patients prior to liver transplantation? Are 6-month mandated abstinence requirements justified by the evidence? Approximately 15% of patients started drinking within the first 6 months (20–30% of patients resume heavy alcohol drinking within 5 years) 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

8 Liver transplantation for alcoholic liver disease: current concepts and length of sobriety.
Lim and Keeffe. Liver Transpl Oct;10(10 Suppl 2):S31-8. How often do patients with alcoholic liver disease experience relapse following liver transplantation? Are there reliable ways to predict relapse in patients prior to liver transplantation? Are 6-month mandated abstinence requirements justified by the evidence? There are few reliable predictors of relapse in alcoholic patients, whether or not they undergo liver transplantation 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

9 Liver transplantation for alcoholic liver disease: current concepts and length of sobriety.
Lim and Keeffe. Liver Transpl Oct;10(10 Suppl 2):S31-8. How often do patients with alcoholic liver disease experience relapse following liver transplantation? Are there reliable ways to predict relapse in patients prior to liver transplantation? Are 6-month mandated abstinence requirements justified by the evidence? Although not supported by all studies, abstinence of fewer than 6 months prior to transplantation may be a reasonable predictor of relapse. 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

10 20% patients showed a relapse to alcohol drinking.
Efficacy of pretransplant 6 month abstinence in 15 ALD patients who underwent LDLT Results 20% patients showed a relapse to alcohol drinking. The cumulative 1-, 3-, and 5-year relapse rates were 6.7%, 20%, and 20%. The relapse rates in patients who did and did not maintain 6 months of abstinence were 9.1% vs. 50% Efficacy of 6-month pretransplant abstinence for patients with alcoholic liver disease undergoing living donor liver transplantation.

12 Why is it so hard for an alcoholic to keep abstinence from alcohol for 6 months ?
Chronic alcohol abuse leads to dysfunction of Prefrontal cortex Mesolimbic dopamine pathway 한국간담췌외과학회 제44차 춘계학술대회 년4월1일 연세의대 정신과학교실 정 영 철

13 There are various types of “Alcohol-related Brain Damage”
Frequent concomitants of alcoholism are liver disease (steatosis, hepatitis and cirrhosis), cardiovascular disease and malnutrition. Alcohol-related CNS disorders include hepatic encephalopathy, Wernicke encephalopathy, Korsakoff syndrome, Marchiafava–Bignami disease and central pontine myelinolysis. Zahr et al. Nature Reviews Neurology (2011)

14 Graded brain-volume deficits in Alcoholism and Korsakoff’s syndrome
Healthy Control Alcohol Us Disorder AUD + Korsakoff

15 The Prefrontal cortex is vulnerable to Alcohol-related Brain Damage
Healthy Control Young AUD (30s) Old AUD (50s) (Z score) -1 -2

16 “Sub-clinical” Frontotemporal dementia
Frontotemporal dementia involve extreme changes in behavior & personality These include: Increasingly inappropriate actions Loss of empathy Lack of judgment and inhibition Apathy Repetitive compulsive behavior Lack of awareness of behavioral changes Frontotemporal dementia Alzheimer’s dementia

17 Why is it so hard for an alcoholic to keep abstinence from alcohol for 6 months ?

19 Healthy Control Drug Abuser
Cocaine METH Heroine Alcohol Neural plastic changes of Mesolimbic dopamine pathway ① During Resting state Baseline striatal [11C] raclopride binding ▼ = Dopamine D2 receptors down regulation

20 Neural plastic changes of Mesolimbic dopamine pathway ②
When Activated Placebo Methylphenidate Healthy Control Decrease in dopamine release by activation Cocaine Abuser

21 Mesolimbic Dopamine Reward Pathway is Shared by other Natural rewards
Alcohol

22 Abnormal activation of Mesolimbic dopamine pathway
Chronic alcohol abuse Abnormal activation of Mesolimbic dopamine pathway Neural plastic changes Dopamine receptor down-regulation Decrease in dopamine release by activation Tolerance of alcohol Apathy toward Natural rewards Compulsive use of alcohol

24 Disulfiram

25 Naltrexone Acamprosate Disulfiram μ Opioid antagonist NMDA antagonist
GABA agonist Disulfiram

26 Nalterxone vs. Acamprosate
Naltrexone Acamprosate Onset Rapid Slow Long term efficacy No Yes Maintain abstinence Reduce Heavy drinking Compliance /Side effects Variable Good Interaction with alcohol Hepatic impact high dose(>100mg) Dependence potential

27 How effective are anti-craving agents?
Return to Any drinking (= Maintain Abstinence) Risk difference Naltrexone - 5% ( ~ 0.00) P=0.02 Acamprosate - 9% ( ~ ) P<0.001 Disulfiram - 4% ( ~ +0.02) P=0.48 Return to Heavy drinking (= Prevent Relapse) - 9% ( ~ ) - 1% ( ~ +0.03) P=0.67 Jonas et al.
