What is the treatment approach for a patient with Alcohol Use Disorder (AUD) and co-occurring Anxiety Disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria?

Treatment Approach for Alcohol Use Disorder with Co-occurring Anxiety Disorder

For patients with co-occurring Alcohol Use Disorder (AUD) and anxiety disorder, a specialized treatment approach that addresses both conditions simultaneously is essential, with benzodiazepines as the first-line treatment for alcohol withdrawal followed by integrated psychotherapy and targeted pharmacotherapy. 1, 2

Initial Assessment and Diagnosis

• Use the Alcohol Use Disorders Identification Test (AUDIT) as the gold standard screening tool to assess AUD severity 1, 2
• Apply DSM-V criteria to determine AUD severity: mild (2-3 criteria), moderate (4-5 criteria), or severe (6+ criteria) 1
• Evaluate whether anxiety disorder is independent of or concurrent with alcohol dependence, as independent disorders require specific treatment while concurrent disorders may resolve with alcohol cessation 1
• Screen for other substance use, particularly nicotine, as alcoholics tend to be heavier smokers and require more intensive support for smoking cessation 1

Management of Alcohol Withdrawal Syndrome

• Assess for alcohol withdrawal syndrome (AWS) using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar), with scores >8 indicating moderate AWS and ≥15 indicating severe AWS 1
• Administer benzodiazepines as the 'gold standard' treatment for AWS to reduce both withdrawal symptoms and the risk of seizures/delirium tremens 1
• Use short or intermediate-acting benzodiazepines (e.g., lorazepam, oxazepam) in patients with hepatic dysfunction rather than long-acting ones 1
• Limit benzodiazepine use to the initial 10-14 days of treatment due to potential for abuse, especially in patients with AUD 1

Psychotherapeutic Interventions

• Implement specialized cognitive behavioral therapy (CBT) designed to both reduce anxiety symptoms and weaken the links between anxiety and drinking motivation, which has shown superior alcohol outcomes compared to anxiety reduction alone 3, 4
• Use the FRAMES model (Feedback, Responsibility, Advice, Menu, Empathy, Self-efficacy) for brief motivational interventions as a first-line approach 5, 2
• Consider motivational enhancement therapy (MET) to strengthen commitment to change during the contemplation/preparation stage 2
• Incorporate behavioral therapy with relaxation techniques and assertive training to help patients use methods other than alcohol to alleviate anxiety 2
• Actively encourage engagement with Alcoholics Anonymous (AA) or other mutual help groups, which has demonstrated high effectiveness in maintaining abstinence 5, 2

Pharmacotherapy Options

• For patients without advanced alcoholic liver disease:

  • Naltrexone (50mg daily) to reduce relapse to heavy drinking and drinking frequency 5, 2
  • Acamprosate to help maintain abstinence, particularly in recently abstinent patients 5, 2
  • Avoid disulfiram in patients with severe ALD due to potential hepatotoxicity 1

• For patients with advanced alcoholic liver disease:

  • Baclofen represents the only alcohol pharmacotherapy tested in patients with significant liver disease, with demonstrated safety and efficacy in promoting abstinence 1, 2
  • Avoid naltrexone in patients with ALD due to potential hepatotoxicity 1, 2

• For anxiety treatment in AUD patients:

  • Consider monoamine oxidase inhibitors, tricyclic antidepressants, or non-benzodiazepine anxiolytics for panic disorder with or without agoraphobia, which are especially prevalent among alcoholics 6
  • Avoid long-term benzodiazepine use for anxiety management due to cross-tolerance with alcohol and high abuse potential in this population 6

Special Considerations for Treatment Integration

• Patients who report drinking to cope (DTC) with anxiety benefit more from specialized CBT that addresses the functional link between anxiety and alcohol use compared to treatments focused only on anxiety reduction 4
• Standard interventions for anxiety disorders or AUDs may need to be modified and combined in targeted ways to accommodate the unique needs of people with both disorders 7
• Recognize that the co-occurrence of anxiety and AUD is associated with a complex clinical presentation requiring an integrated understanding of developmental pathways 7
• Self-report scales like the Brief Scale for Anxiety (BSA) and State-Trait Anxiety Inventory (STAI-Y-2) should not be relied upon as substitutes for clinical diagnosis of anxiety disorders in AUD patients 8

Follow-up and Monitoring

• Schedule regular follow-up appointments every 1-3 months to assess progress and adjust treatment as needed 5
• Monitor for relapse triggers, particularly anxiety symptoms that may precipitate alcohol use 3, 4
• Involve family members in treatment when appropriate to strengthen support systems 2
• Emphasize that continued engagement with treatment is essential for long-term success, even after achieving initial abstinence 5
