Alcohol Use, Abuse in HIVHIV Quality of Care Advisory CommitteeThursday, December 14 Joseph Conigliaro, MD, MPH Center for Enterprise Quality and Safety University of Kentucky
Objectives • To review present data assessing the role of alcohol use and abuse among patients with HIV/AIDS • Outline potential therapeutic approaches
Alcohol Abuse/ Dependence Harmful Drinking Hazardous Drinking Non-Hazardous Drinking Tertiary Prevention Secondary Prevention Problem Drinking Primary Prevention Spectrum of Alcohol Problems
Hazardous & Safe Drinking Hazardous Drinking Men: 16 drinks/week Women: 12 drinks/week Sanchez-Craig Am J Pub Health 1995 Safe Drinking Men: 14 drinks/week Women: 7 drinks/week NIAAA 1995
Converging Epidemics • HIV/AIDS • 40,000-60,000 new cases per year • Alcohol • 110 million use • 32-40 million hazardous drinkers • 11-14 million alcohol dependent • Both • 21% hazardous drinking HIV • 32% alcohol abuse/dependence Bryant, Substance Use and Misuse 2006
Alcohol Use in VACS 3 p <0.0005 Conigliaro, et al JAIDS 2003
High Alcohol Intake • Decreases immune response - predisposes to infectious diseases and cancer. • Immune deficiencies become more pronounced as liver function and nutritional status is compromised. • Cells affected include: neutrophils, monocyte/macrophages, CD4 T lymphocytes (TH1 And TH2), and natural killer cells.
High Alcohol Intake Evidence suggests that acute alcohol consumption and binge drinking transiently suppresses immune responses and impairs host defenses Implications: Enhanced susceptibility to infectious diseases and cancer
Alcohol Abuse • Increases incidence of some cancers • Oral cavity and pharynx • Larynx • Esophagus • Liver • Moderately associated with: • Breast cancer • Colorectal cancer
Chronic Alcohol Use • Increases incidence of: • Bacterial pneumonia • Septicemia • Tuberculosis • Hepatitis C • HIV (?) • Less common diseases such as: • Meningitis • Lung abscess • Diphtheria • Cellulitis
Alcohol and HIV/AIDS • Increased viral load • Risky sexual behavior • Decreased adherence/Non adherence to antiretroviral therapy • Increased susceptibility to ADRs • Susceptibility to CNS injury • Susceptibility to immune dysfunction • Greater comorbidity (TB, HCV, Heart, Liver, Neurologic Disease)
Alcohol use among HIV infected persons affects adherence to antiretroviral therapy and may be associated with higher viral load Cook et al JGIM 2001; Samet et al JGIM 2000 Alcohol and HIV
Alcohol and HIV/AIDS • Hazardous Drinking • Reduced adherence, increased viral replication • Decreased ART utilization OR 0.65 • 2 week Adherence OR 0.46 • Viral Suppression OR 0.76 Chander et al JAIDS 2006

Alcohol/HIV and Immune Function • Chronic Binge Alcohol Consumption accelerates progression of SIV disease • More rapid disease progression to end-stage disease Bagby et al Alc Clin Exp Res 2006
Hepatitis C and Alcohol • Alcohol use may accelerate hepatitis C (HCV) • Progression to cirrhosis • Risk of hepatocellular carcinoma • Decreases response to HCV treatment • HCV Treatment Guidelines • “abstinence … before and during antiviral therapy” • “even moderate levels of consumption may accelerate disease progression”
HIV/HCV Coinfection • Common because of modes of transmission • National VA – 29% by ICD-9 codes • VACS 3 – 43% of those tested • HIV infection may accelerate • Progression of HCV infection • Alcohol induced liver damage • May complicate HCV treatment
Transaminases in Current Drinkers p<0.0005
Alcohol and HIV/AIDS • Higher incidence of Hepatocellular carcinoma • Alcohol/abuse-dependence OR 1.85 McGinnis, et al J Clin Onc 2006
Alcohol Use in HIV • Alcohol Use/Abuse/ HIV and Neuropsychological Performance • Heavy drinkers (>21 d/week) performed worse: • Psychomotor speed • Reaction time • Motor speed Durvasula et al JCEN 2006
Alcohol and HIV/AIDS • Risky sexual behavior • HIV negative/Problem Drinking • Unprotected anal intercourse Irwin et al AIDS and Behavior 2006 • HIV positive • Multiple sexual partners • Unprotected sex Cook et al Medical Care 2006
We don’t know to what extent: alcohol exacerbates HIV disease progression or HIV associated conditions alcohol mitigates effectiveness and increases toxicity of antiretroviral treatment HIV infection increases the risk of common complications of alcohol Alcohol and HIV
Median estimated survival from diagnosis 15-20 yrs (Markov modeling) twice expected survival prior to 1992 people are growing older with HIV more effective antiretroviral treatment Older people are contracting HIV infection # of persons 65 years at diagnosis has grown 10-fold in 10 years HIV/AIDS Is a Chronic Disease King et al Medical Decision Making 2000
Patient Outcomes Aging Comorbid Disease (Alcohol Use/Abuse) “Primary” Disease (HIV) “Primary” Disease Treatment
Changing Profile of HIV Conditions • Lower prevalence of “HIV related conditions” • pnuemocystis, Kaposi’s, mycobacterium • Increased prevalence of “Non HIV related conditions” • hepatitis, hyperlipidemia, diabetes • now exceed HIV related conditions

Provider Awareness of Alcohol • Health care providers often do not detect alcohol problems among their patients • Assess HIV provider awareness of hazardous alcohol use and what patient characteristics are associated with provider failure to identify it
Measure % AUDIT Score 8 Last year 20 33 Drinks 6 drinks on one occasion (Binge) AUDIT 8 and/or Binge 36 Provider reports patient currently drinks too much 13 Provider Awareness of Alcohol Conigliaro, et al JAIDS 2003
Provider Awareness of Alcohol • AUDIT 8 and/or Binge and provider report of drinking too much • Kappa 0.20 • Sensitivity 22% • Specificity 95%
Provider Awareness of Alcohol • HCV Negative • 23 (12%) of 186 drinkers were recognized by provider • Kappa 0.07 • Sensitivity 12% (8% - 18%) • Specificity 94% (90% - 97%) • HCV Positive • 29 (33%) of 88 drinkers were recognized by provider • Kappa 0.28 • Sensitivity 33% (23% - 44%) • Specificity 91% (87% - 95%)
Motivational Enhancement Feedback • Specific and relative to mental, physical & psychosocial health Responsibility • Stated explicitly by CALM Advice • Simple and explicit; given as a prescription Menu of options • Patient chooses goal that matches needs & situation • Increases perceived personal choice and control Empathy • Acknowledge difficulty of change • By health care provider Self efficacy • Statements of hope and optimism • By health care provider
Motivational Enhancement • 4-sixty minute MI sessions over 12 weeks • 51 – intervention/control • Healthy Choices • Reductions in risky sexual behavior (unprotected sex) • Improved viral load • Reduced alcohol use Naar-King et al, 2006 AIDS Education and Prevention
Supporting alcohol reduction in HIV+ patients: a training for HIV care providers (1) Provider training to encourage implementation of NIAAA's BI • (a) how to screen patients for alcohol use, • (b) how to counsel to reduce using motivational interviewing; (2) Training in 4 NYC AIDS Centers to obtain preliminary data regarding impact on provider (immediate, 1- and 4- months post- training) with knowledge, attitudes, self-efficacy, collective organizational efficacy, and use of Bl (3) Preliminary data to examine impact of training on • (a) patients' alcohol reduction • (b) HIV provider organization- (i) organizational climate towards dealing with alcohol and HIV and HIV/HCV co-infection; and (ii) organization's expansion of existing alcohol reduction services and/or implementation of new services to reduce alcohol consumption Strauss National Development & Research Institutes
Interactive Computer Programs & BIs • Assess drinking status & readiness to change • Initiate provider delivered BIs • Prepare patient & provider for targeted session • Saves time • Facilitate individualized feedback immediately upon submission of data • Lower-cost & customized intervention to more drinkers • Provide anonymity, convenience
Computer Assisted Lifestyle Management (CALM) • Interactive Computer Program • Identifies hazardous drinkers • Alcohol Use Disorders Identification Test (AUDIT) • Quantity and frequency of consumption • Alcohol related consequences • Readiness to change
CALM • Delivers Brief Intervention • Patients & providers explore ETOH severity, consequences, goals & Rx barriers • Brief negotiation using FRAMES & Stages of Change • Computer intervention pulls from electronic medical record
Conclusions • Alcohol use and hazardous drinking are common among HIV/AIDS • High rates of current alcohol use • More HCV + patients have quit drinking • High prevalence of hazardous alcohol use • More HCV + drinkers are at hazardous levels • Associated with HIV disease severity, hepatic comorbidity and anemia • Associated with comorbid disease
Conclusions • Providers often unaware of alcohol use • Providers more oftenmissed alcohol problems among patients with less severe HIV and without evidence of liver disease. • Better awareness for HCV + drinkers • Patients report seldom being counseled to stop or limit alcohol use
Implications • Increased screening for alcohol use/abuse, especially in HCV + patients • Interventions targeted at alcohol use may improve health of HIV patients • Brief Interventions based on motivational interviewing promising • Use of interactive computers and provider based training
