1 WHAT S NEW UPDATE: ADDICTIONS DECEMBER 2012 Nzinga Harrison, M.D. Senior Vice President for East Coast Operations Medical Director UPDATES General Diagnostic Biological Psychological Social 1

2 Addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry. Dysfunction in these circuits leads to characteristic biological, psychological, social and spiritual manifestations... Like other chronic diseases, addiction often involves cycles of relapse and remission. Without treatment or engagement in recovery activities, addiction is progressive and can result in disability or premature death. American Society of Addiction Medicine. April 19, 2011 TIP 54: Managing Chronic Pain in Adults With or in Recovery From Substance Use Disorders Equips clinicians with practical guidance and tools for treating chronic pain in adults with a history of substance abuse. Discusses chronic pain management, including treatment with opioids, and offers information about substance abuse assessments and referrals. 2

3 Slated for publication in May 2013 Category Change Substance-Related Disorders becomes Substance Use and Addictive Disorders Gambling Disorder moved from Impulse Control Disorders NOS to this category Disorders reorganized according to substance rather than diagnosis Section III: Conditions that require further research Neurobehavioral Disorder Associated With Prenatal Alcohol Exposure Caffeine Use Disorder Internet Use Disorder Substance Abuse and Dependence combined into one disorder: Substance Use Disorder with Updated Severity Specifiers Updated Remission Specifiers 3

4 A. A problematic pattern of alcohol use leading to clinically significant impairment or distress. B. Two (or more) of the following occurring within a 12-month period: 1. Alcohol is often taken in larger amounts or over a longer period than was intended 2. There is a persistent desire or unsuccessful effort to cut down or control alcohol use 3. A great deal of time is spent in activities necessary to obtain alcohol, use the substance, or recover from its effects 4. Recurrent alcohol use resulting in a failure to fulfill major role obligations at work, school, or home (e.g., repeated absences or poor work performance related to alcohol use; substance-related absences, suspensions, or expulsions from school; neglect of children or household) 5. Continued alcohol use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance 6. Important social, occupational, or recreational activities are given up or reduced because of alcohol use 7. Recurrent alcohol use in situations in which it is physically hazardous (e.g., driving an automobile or operating a machine when impaired by substance use 8. Alcohol use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance 9. Tolerance, as defined by either or both of the following: a. A need for markedly increased amounts of alcohol to achieve intoxication or desired effect b. Markedly diminished effect with continued use of the same amount of the substance 10. Withdrawal, as manifested by either of the following: a. The characteristic withdrawal syndrome for alcohol (refer to Criteria A and B of the criteria set for Withdrawal) b. The same (or a closely related) substance is taken to relieve or avoid withdrawal symptoms 11. Craving or a strong desire or urge to use alcohol Severity Specifiers The Severity of each Substance Use Disorder is based on: - 0 criteria or 1 criterion: No diagnosis criteria: Mild Substance Use Disorder criteria: Moderate Substance Use Disorder - 6 or more criteria: Severe Substance Use Disorder Remission Specifiers Early Remission. This specifier is used if, for at least 3 months, but for less than 12 months, the individual does not meet any of the criteria 1-10 for a Substance Use Disorder (i.e. none of the criteria except for Criterion 11, Craving or a strong desire or urge to use a specific substance ). Sustained Remission. This specifier is used if none of the criteria 1-10 for a Substance Use Disorder have been met at any time during a period of 12 months or longer (i.e. none of the criteria met except for Criterion 11, Craving or a strong desire or urge to use a specific substance ). In a Controlled Environment. This additional specifier is used if the individual is in an environment where access to alcohol and controlled substances is restricted, and no criteria for a Substance Use Disorder have been met. Examples of these environments are closely supervised and substance-free jails, therapeutic communities, and locked hospital units. 4

8 History of Anti-Addiction vaccines starts nearly 40 years ago with Opiate Vaccines Advent of Methadone and Naltrexone pushed it to the background Idea revived with epidemic rise in stimulant addiction Conjugate vaccines exist for cocaine and nicotine Vaccines in development for methamphetamine and opiates Successful clinical trials Many patients do not produce a sufficient antibody response Those patients who do produce a response have excellent abstinence rates COCAINE VACCINE: TA-CD Anti-cocaine monoclonal antibody Antibodies sequester cocaine and retard its ability to get into the CNS Enzymes in blood vessel metabolize cocaine 8

9 COCAINE VACCINE: TA-CD Anti-cocaine monoclonal antibody Antibodies sequester cocaine and retard its ability to get into the CNS Enzymes in blood vessel metabolize cocaine COCAINE VACCINE: TA-CD Phase I and Phase 2A studies completed by 2005 Multisite Phase2B studies ongoing On-track to be first FDA approved addiction vaccine 9

10 COCAINE VACCINE: TA-CD Will likely be recommended in the context of a treatment program to improve compliance Vaccine doses at 0, 2, 4, 8, 12 weeks Booster shot at 6, 9, 12, 15, 18, 21, 24 months VOLUME 91 NUMBER 1 January NICOTINE VACCINE Development is of great interest to pharmaceutical industry Three pharmaceutical companies have moved vaccines forward to clinical trials UK, Switzerland GlaxoSmithKline NICOTINE VACCINE GlaxoSmithKline vaccine is most advanced: NicVAX 5 successful Phase I/II trials involving more than 475 subjects Demonstrated immunogenic, tolerable, correlation between antibody level, smoking cessation and abstinence at 12 months Requires multiple doses VOLUME 91 NUMBER 1 January

11 METHAMPHETAMINE VACCINE In Pre-clinical development Development has been difficult OPIATE VACCINE Less necessary given naltrexone, methadone Does not cover synthetic narcotics which are the fastest growing segment VOLUME 91 NUMBER 1 January Prefrontal Cortex Stimulation as Treatment for Crack-cocaine Addiction repeated transcranial Direct Current Stimulation over the left dorsolateral prefrontal cortex in the treatment of crackcocaine addiction Enzymatic therapies aimed at accelerating the metabolism of Cocaine Butyrylcholinesterase Cocaine Esterase Cocaine Hydrolase 11

12 re-engineering of human plasma butyrylcholinesterase has led to enzymes that destroy cocaine so efficiently that they prevent or interrupt drug actions in the CNS even though confined to the blood stream gene-transfer technology has made it possible to deliver such enzymes by endogenous gene transduction at high levels for periods of a year or longer after a single treatment. 12

13 SBIRT is a comprehensive, integrated, public health approach to the delivery of early intervention and treatment services for persons with substance use disorders, as well as those who are at risk of developing these disorders. Primary care centers, hospital emergency rooms, trauma centers, and other community settings provide opportunities for early intervention with at-risk substance users before more severe consequences occur. Since 2003, SAMHSA has funded seventeen (17) Medical Residency Cooperative Agreements fifteen (15) State Cooperative Agreements twelve (12) Targeted Capacity Expansion Campus Screening and Brief Intervention (SBI) Grants. MBRP offers skills in cognitive-behavioral relapse prevention integrated with mindfulness meditation Those randomized to MBRP, as compared with those in a control group, demonstrated significantly lower rates of substance use and greater decreases in craving following treatment. Individuals in MBRP did not report increased craving or substance use in response to negative affect. Psychol Addict Behav Jul 9. [Epub ahead of print] 13

14 Colorado, Washington Become First States to Legalize Recreational Marijuana Colorado's Proposition 64 to the state's constitution makes it legal for anyone over the age of 21 to possess marijuana and for businesses to sell it. A similar measure on the ballot in Washington State legalizes small amounts of marijuana for people over

15 The number of text messaging interventions designed to initiate and support behavioral health changes have been steadily increasing over the past 5 years. Messaging interventions can be tailored and adapted to an individual's needs in their natural. Psychol Addict Behav Sep 10. [Epub ahead of print] Fifty individuals enrolled in intensive outpatient substance abuse treatment completed an assessment battery relating to preferred logistics of mobile interventions, behavior change strategies, and types of messages they thought would be most helpful to them at different time points. Psychol Addict Behav Sep 10. [Epub ahead of print] Results 98% participants were potentially interested in using text messaging as a continuing care strategy. Individuals tended to prefer benefit driven over consequence driven messages Differences in the perceived benefits of change among individuals predicted message preference.
