Adipose lipolysis is important for ethanol to induce fatty liver in the National Institute on Alcohol Abuse and Alcoholism murine model of chronic and binge ethanol feeding.

BACKGROUND AND AIMS: Alcohol-associated liver disease (ALD) pathologies include steatosis, inflammation, and injury, which may progress to fibrosis, cirrhosis, and cancer. The liver receives ~60% of fatty acids from adipose tissue triglyceride hydrolysis, but the role of this lipolytic pathway in ALD development has not been directly examined in any genetic animal models with selective inactivation of adipose lipolysis. APPROACH AND RESULTS: Using adipose-specific comparative gene identification-58 (CGI-58) knockout (FAT-KO) mice, a model of impaired adipose lipolysis, we show that mice deficient in adipose lipolysis are almost completely protected against ethanol-induced hepatic steatosis and lipid peroxidation when subjected to the National Institute on Alcohol Abuse and Alcoholism chronic and binge ethanol feeding model. This is unlikely due to reduced lipid synthesis because this regimen of ethanol feeding down-regulated hepatic expression of lipogenic genes similarly in both genotypes. In the pair-fed group, FAT-KO relative to control mice displayed increased hepatocyte injury, neutrophil infiltration, and activation of the transcription factor signal transducer and activator of transcription 3 (STAT3) in the liver; and none of these were exacerbated by ethanol feeding. Activation of STAT3 is associated with a marked increase in hepatic leptin receptor mRNA expression and adipose inflammatory cell infiltration. CONCLUSIONS: Our findings establish a critical role of adipose lipolysis in driving hepatic steatosis and oxidative stress during ALD development.

Adding Inflammatory Markers and Refining National Institute on Alcohol Abuse and Alcoholism Criteria Improve Diagnostic Accuracy for Alcohol-associated Hepatitis.

BACKGROUND & AIMS: Although histology is considered the gold standard for diagnosis of alcohol-associated hepatitis (AH), it is not required for entry into therapeutic studies if patients meet National Institute on Alcohol Abuse and Alcoholism (NIAAA) consensus criteria for probable AH. Our aim was to assess the diagnostic accuracy of NIAAA criteria against liver biopsy and to explore new criteria to enhance diagnostic accuracy for AH. METHODS: A total of 268 consecutive patients with alcohol-related liver disease with liver biopsy were prospectively included: 210 and 58 in the derivation and validation cohorts, respectively. NIAAA criteria and histological diagnosis of alcoholic steatohepatitis (ASH) were independently reviewed by clinical investigators and pathologists from Hospital Clínic and Mayo Clinic. Using biopsy-proven ASH as gold standard we determined diagnostic capability of NIAAA criteria and proposed the new improved criteria. RESULTS: In the derivation cohort, diagnostic accuracy of NIAAA for AH was modest (72%) due to low sensitivity (63%). Subjects who did not meet NIAAA with ASH at liver biopsy had lower 1-year survival compared with subjects without ASH (70% vs 90%; P < .001). NIAAAm-CRP criteria, created by adding C-reactive protein and modifying the variables of the original NIAAA, had higher sensitivity (70%), accuracy (78%), and specificity (83%). Accuracy was also higher in a sensitivity analysis in severe AH (74% vs 65%). In the validation cohort, NIAAAm-CRP and NIAAA criteria had a sensitivity of 56% vs 52% and an accuracy of 76% vs 69%, respectively. CONCLUSION: NIAAA criteria are suboptimal for the diagnosis of AH. The proposed NIAAAm-CRP criteria may improve accuracy for noninvasive diagnosis of AH in patients with alcohol-related liver disease.

Computerizing NIAAA's Best Practices for Youth Screening and Brief Intervention: A Proof-of-Concept Pilot Study of an Automated Alcohol Screening and Intervention Resource Tool.

This article reports findings from formative research on translating key elements of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and American Academy of Pediatrics Practitioner's Guide for pediatric alcohol misuse to a computerized web- and mobile-compatible format with patient risk screening and tailored decision support content. Five practitioners at an urban primary care center used a prototype computerized version of the NIAAA/American Academy of Pediatrics Practitioner's Guide with 80 adolescent patients during routine health-care visits. Practitioners reported a high level of practitioner and adolescent patient engagement and satisfaction with the prototype. Study findings indicate that computerization of the NIAAA Practitioner's Guide is feasible and well accepted by providers and adolescent patients and could be useful for addressing alcohol misuse in primary care settings.

Methodology and Demographics of a Brief Adolescent Alcohol Screen Validation Study.

OBJECTIVE: The aim of this study was to determine the psychometric properties of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) 2-question alcohol screen within 16 Pediatric Emergency Care Applied Research Network pediatric emergency departments. This article describes the study methodology, sample characteristics, and baseline outcomes of the NIAAA 2-question screen. METHODS: Participants included 12- to 17-year-olds treated in one of the participating pediatric emergency departments across the United States. After enrollment, a criterion assessment battery including the NIAAA 2-question screen and other measures of alcohol, drug use, and risk behavior was self-administered by participants on a tablet computer. Two subsamples were derived from the sample. The first subsample was readministered the NIAAA 2-question screen 1 week after their initial visit to assess test-retest reliability. The second subsample is being reassessed at 12 and 24 months to examine predictive validity of the NIAAA 2-question screen. RESULTS: There were 4834 participants enrolled into the study who completed baseline assessments. Participants were equally distributed across sex and age. Forty-six percent of the participants identified as white, and 26% identified as black. Approximately one quarter identified as Hispanic. Using the NIAAA 2-question screen algorithm, approximately 8% were classified as low risk, 12% were classified as moderate risk, and 4% were classified as highest risk. Alcohol use was less likely to be reported by black participants, non-Hispanic participants, and those younger than 16 years. DISCUSSION: This study successfully recruited a large, demographically diverse sample to establish rates of the NIAAA screen risk categories across age, sex, ethnicity, and race within pediatric emergency departments.

The Impact of Alcohol Use on Frontal White Matter in HIV.

BACKGROUND: Alcohol use disorder (AUD) is prevalent among individuals diagnosed with human immunodeficiency virus (HIV), and both HIV and alcohol use have been shown to negatively affect the integrity of white matter pathways in the brain. Behavioral, functional, and anatomical impairments have been linked independently to HIV and alcohol use, and these impairments have bases in specific frontally mediated pathways within the brain. METHODS: Magnetic resonance imaging data were acquired for 37 HIV+ participants without dementia or hepatitis C. Imaging data were processed through the FreeSurfer and TraCULA pipelines to obtain 4 bilateral frontal white matter tracts for each participant. Diffusion metrics of white matter integrity along the highest probability pathway for each tract were analyzed with respect to demographics, disease-specific variables, and reported substance use. RESULTS: Significantly increased axial diffusivity (decreased axonal integrity) and a trending increase in mean diffusivity were observed along the anterior thalamic radiation (ATR) in participants with a history of AUD. A diagnosis of AUD explained over 36% of the variance in diffusivity along the ATR overall when accounting for clinical variables including nadir CD4 and age-adjusted HIV infection length. CONCLUSIONS: This study provides evidence of HIV-related associations between alcohol use and indicators of axonal integrity loss along the ATR, a frontal pathway involved in the inhibition of addictive or unwanted behaviors. Reduced axonal integrity of this pathway was greatest in HIV+ participants with an AUD, even when considering the effect of age-adjusted disease length and severity (nadir CD4). This finding implicates a potential biological mechanism linking reduced integrity of frontal white matter to the high prevalence of AUD in an HIV+ population without dementia or hepatitis C.

Differences Between Treatment-Seeking and Nontreatment-Seeking Alcohol-Dependent Research Participants: An Exploratory Analysis.

BACKGROUND: Alcoholism is a chronic relapsing disorder with complex behavioral and functional heterogeneity. To date, attempts to characterize subgroups of alcohol-dependent (AD) individuals have largely been focused on categorical distinctions based on behaviors such as ability to abstain, age of onset, and drinking motives, but these have failed to yield predictors of treatment response and disease course. The distinction between AD individuals who are or are not interested in treatment holds significant implications for interpreting results of human laboratory studies with nontreatment seekers and clinical trials with treatment-seeking AD patients. However, despite their crucial role in alcohol-related research, these 2 groups are poorly defined. In this exploratory analysis, we attempt to better define the phenotypic differences between these 2 experimentally relevant populations. METHODS: We analyzed data from AD individuals who participated in screening protocols to evaluate their suitability for participation in either treatment or nontreatment research studies at NIAAA. Scores on individual measures from a battery of behavioral, neuropsychological, and blood laboratory measures were compared between those who presented seeking treatment for AD and those who were not seeking treatment. Differences in each measure were assessed between the 2 groups. In addition, we explored whether significant differences were apparent when drinking behavior was used as a covariate. RESULTS: Treatment seekers manifested more impairment compared to nontreatment seekers on a wide variety of measures in the following categories: alcohol drinking, personality, impulsivity, trauma/stress, cognition, aggression, mood, and liver enzyme tests. Treatment seekers endorsed a greater number of AD criteria. Several measures including elevations in liver enzyme tests remained significantly different between the 2 groups when average daily alcohol consumption per drinking day was used as a covariate. CONCLUSIONS: Treatment-seeking, compared to nontreatment-seeking AD subjects who present for alcohol-related research studies, differ in characteristics beyond the quantity of alcohol consumption. Implications of these differences with respect to clinical research for treatments of AD are discussed.

Liver Injury and Endotoxemia in Male and Female Alcohol-Dependent Individuals Admitted to an Alcohol Treatment Program.

BACKGROUND: Interactions between the liver, the gut, and the immune system are critical components of alcoholic liver disease (ALD). The aim of this study was to explore the associations between alcohol-induced liver injury, endotoxemia, and inflammation at admission and over time during abstinence, as well as to examine the sex-related differences in these parameters in alcohol-dependent individuals admitted to an alcohol treatment program. METHODS: A cohort of 48 otherwise healthy participants with alcohol use disorder, but no clinical signs of alcoholic liver injury (34 males [M]/14 females [F]) admitted to an alcohol detoxification program, was stratified into 2 groups based on baseline plasma alanine aminotransferase (ALT) levels (as a marker of liver injury). Group 1 (ALT < 40 U/l, 7M/8F) and Group 2 (ALT ≥ 40 U/l, 27M/6F) were identified. Plasma biomarkers of liver damage, endotoxemia, and inflammation were examined at baseline, day 8, and day 15 of the admission. The drinking history was also evaluated. RESULTS: Sixty-nine percent of patients had elevated ALT and other markers of liver damage, including aspartate aminotransferase and cytokeratin 18 (CK18 M65 and CK M30) at baseline, indicating the presence of mild ALD. Elevated CK18 M65:M30 ratio suggested a greater contribution of necrotic rather than apoptotic hepatocyte cell death in the liver injury observed in these individuals. Females showed greater elevations of liver injury markers compared to males, although they had fewer drinks per day and shorter lifetime duration of heavy drinking. Liver injury was associated with systemic inflammation, specifically, elevated plasma tumor necrosis factor-alpha levels. Compared to patients without liver injury, patients with mild ALD had greater endotoxemia (increased serum lipopolysaccharide levels), which decreased with abstinence and this decrease preceded the drop in CK18 M65 levels. CONCLUSIONS: The study documented the association of mild alcohol-induced liver injury and endotoxemia, which improved with 2 weeks of abstinence, in a subset of individuals admitted to an alcohol detoxification program.

Use of a crossed high alcohol preferring (cHAP) mouse model with the NIAAA-model of chronic-binge ethanol intake to study liver injury.

AIMS: This study sought to compare mice bred to preferentially consume high amounts of alcohol (crossed-high alcohol preferring, cHAP) to c57BL/6 (C57) mice using a chronic-binge ethanol ingestion model to induce alcoholic liver disease (ALD). METHODS: Male C57 and cHAP mice were randomized to a Lieber-DeCarli control (LDC) diet, Lieber-DeCarli 5% (v/v) ethanol (LDE) diet or free-choice between 10% (v/v) ethanol in drinking water (EtOH-DW) and DW. After 4 weeks mice were gavaged with either 9 g/kg maltose-dextrin (LDC+MD) or 5 g/kg EtOH (LDE+Binge, EtOH-DW+Binge). Nine hours later tissue and serum were collected and analyzed. RESULTS: cHAP mice on EtOH-DW consumed significantly more ethanol than cHAP or C57 mice maintained on LDE. However, cHAP and C57 mice on the LDE+Binge regiment had greater hepatosteatosis and overall degree of liver injury compared to EtOH-DW+Binge. Changes in pro-inflammatory gene expression was more pronounced in cHAP mice than C57 mice. Analysis of liver enzymes revealed a robust induction of CYP2E1 in C57 and cHAP mice maintained on EtOH-DW+Binge or LDE+Binge. However, while C57 mice exhibited higher basal hepatic glutathione than cHAP mice, these mice appeared more susceptible to oxidative stress following LDE+Binge than cHAP counterparts. CONCLUSIONS: Despite cHAP mice consuming more total ethanol prior to gavage when maintained on EtOH-DW, LDE followed by gavage created a more severe model of ALD in both C57 and cHAP mice. These data suggest factors other than total amount of alcohol consumed affect degree of ALD development in the chronic-binge model in cHAP mice. SHORT SUMMARY: cHAP mice voluntarily consume high amounts of ethanol and exhibited hepatic injury when subject to chronic-binge ethanol feeding with the Lieber-DeCarli diet. However, hepatic injury was reduced in cHAP mice in a chronic-binge model following voluntary high ethanol consumption in drinking water.

The Utility of Including the Strengths of Underage Drinking Laws in Determining Their Effect on Outcomes.

BACKGROUND: To control underage drinking in the United States, which has been associated with an estimated 5,000 deaths and 2.6 million injuries or other harm annually, each state has developed a unique set of laws. Previous research examining these laws' effectiveness has frequently focused on the laws' existence without considering variance in sanctions, enforcement, or exemptions. METHODS: We scored 20 minimum legal drinking age 21 (MLDA-21) laws for their strengths and weaknesses based on (i) sanctions for violating the law, (ii) exceptions or exemptions affecting application, and (iii) provisions affecting the law or enforcement. We then replicated a 2009 study of the effects of 6 MLDA-21 laws in 3 different ways (using identical structural equation modeling): Study 1-8 additional years of data, no law strengths; Study 2-years from the original study, added law strengths; Study 3-additional years, law strengths, serving as an update of the 6 laws' effects. RESULTS: In all 3 studies-and the original study-keg registration laws were associated with both an unexpected significant increase (+11%, p < 0.001) in underage drinking-driver ratios and a notable 25% reduction in per capita beer consumption-opposing results that are difficult to explain. In Study 3, possession and purchase laws were associated with a significant decrease in underage drinking-driver fatal crash ratios (-4.9%, p < 0.001; -3.6%, p < 0.001, respectively). Similarly, zero tolerance and use and lose laws were associated with reductions in underage drinking-driver ratios (-2.8%, p < 0.001; -5.3%, p < 0.001, respectively). CONCLUSIONS: Including strengths and weaknesses of underage drinking laws is important when examining their effects on various outcomes as the model fit statistics indicated. We suggest that this will result in more accurate and more reliable estimates of the impact of the laws on various outcome measures.

Clinical impact of alcohol-related cirrhosis in the next decade: estimates based on current epidemiological trends in the United States.

BACKGROUND: Identifying changes in the epidemiology of liver disease is critical for establishing healthcare priorities and allocating resources to develop therapies. The projected contribution of different etiologies toward development of cirrhosis in the United States was estimated based on current publications on epidemiological data and advances in therapy. Given the heterogeneity of published reports and the different perceptions that are not always reconcilable, a critical overview rather than a formal meta-analysis of the existing data and projections for the next decade was performed. METHODS: Data from the World Health Organization Global Status Report on Alcohol and Health of 2014, Scientific Registry of Transplant Recipients from 1999 to 2012, National Institute on Alcohol Abuse and Alcoholism, and the Centers for Disease Control and Prevention were inquired to determine future changes in the epidemiology of liver disease. RESULTS: Alcohol consumption has increased over the past 60 years. In 2010, transplant-related costs for liver recipients were the highest for hepatitis C (~$124 million) followed by alcohol-related cirrhosis (~$86 million). We anticipate a significant reduction in incidence cirrhosis due to causes other than alcohol because of the availability of high efficiency antiviral agents for hepatitis C, universal and effective vaccination for hepatitis B, relative stabilization of the obesity trends in the United States, and novel, potentially effective therapies for nonalcoholic steatohepatitis. The proportion of alcohol-related liver disease is therefore likely to increase in both the population as a whole and the liver transplant wait list. CONCLUSIONS: Alcohol-related cirrhosis and alcohol-related liver disorders will be the major cause of liver disease in the coming decades. There is an urgent need to allocate resources aimed toward understanding the pathogenesis of the disease and its complications so that effective therapies can be developed.

The prevalence of harmful and hazardous alcohol consumption in older U.S. adults: data from the 2005-2008 National Health and Nutrition Examination Survey (NHANES).

BACKGROUND: Alcohol consumption and its interaction with disease, medication use, and functional status may result in serious health problems, but little information exists about the national prevalence of alcohol-related health risk in older adults. OBJECTIVE: To estimate the prevalence of harmful and hazardous alcohol use and the prevalence of consumption in excess of National Institute of Alcohol Abuse and Alcoholism (NIAAA) recommendations, in people aged 65 and older, and by sex and race/ethnicity sub-group. DESIGN: Cross-sectional, using data from the 2005-2008 National Health and Nutrition Examination Survey of the non-institutionalized U.S. population. PARTICIPANTS: One thousand and eighty-three respondents aged 65 and older who consume alcohol. MAIN MEASURES: Participants' alcohol consumption was classified as Harmful, Hazardous, or Healthwise, in the context of their specific health status, using the Alcohol-Related Problems Survey classification algorithm. KEY RESULTS: Overall, 14.5 % of older drinkers (95 % CI: 12.1 %, 16.8 %) consumed alcohol above the NIAAA's recommended limits. However, when health status was taken into account, 37.4 % of older drinkers (95 % CI: 34.9 %, 40.0 %) had Harmful consumption and 53.3 % (95 % CI: 50.1 %, 56.6 %) had either Hazardous or Harmful consumption. Among light/moderate drinkers, the proportions were 17.7 % (95 % CI: 14.7 %, 20.7 %) and 28.0 % (95 % CI: 24.8 %, 31.1 %), respectively. Male drinkers had significantly greater odds of Hazardous/Harmful consumption than female drinkers (OR = 2.14 [95 % CI: 1.77, 2.6]). Black drinkers had worse health status and significantly greater odds of Hazardous/Harmful consumption than white drinkers (OR = 1.49; 95 % CI: 1.02, 2.17), despite having no greater prevalence of drinking in excess of NIAAA-recommended limits. CONCLUSION: Most older Americans who drink are light/moderate drinkers, yet substantial proportions of such drinkers drink in a manner that is either harmful or hazardous to their health. Older adults with risky alcohol consumption are unlikely to be identified by health care providers if clinicians rely solely on whether patient consumption exceeds the NIAAA-recommended limits.

Federalizing medical campaigns against alcoholism and drug abuse.

CONTEXT: The formation of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the Special Action Office for Drug Abuse Prevention (SAODAP) in the early 1970s dramatically expanded scientific and medical efforts to control alcoholism and drug abuse in the United States. METHODS: Drawing on a variety of primary, secondary, and archival sources, this article describes the creation and early years of these agencies. FINDINGS: I show that while the agencies appeared at roughly the same time, their creation involved separate sets of issues and actors. In addition, I show that SAODAP received more money and resources, even though advocates for alcoholics mobilized a stronger lobbying campaign. CONCLUSIONS: Two factors explain this discrepancy in money and resources: (1) alcoholism was framed as a public health problem, whereas drug abuse was drawn into broader debates about crime and social decline; and (2) alcohol programs relied on congressional support, whereas drug programs found champions at high levels of the Nixon administration. These political and cultural factors help explain why current programs for illegal drugs receive more federal support, despite alcohol's greater public health burden.

Sex differences in college student adherence to NIAAA drinking guidelines.

BACKGROUND: Exceeding nationally recommended drinking limits puts individuals at increased risk of experiencing harmful effects due to alcohol consumption. Both weekly and daily limits exist to prevent harm due to toxicity and intoxication, respectively. It remains unclear how well college students adhere to recommended limits, and whether their drinking is sensitive to the wider sex difference in weekly versus daily drinking limits. METHODS: This study used a daily-level, academic-year-long, multisite sample to describe adherence to NIAAA daily (no more than 4 drinks per day for men, 3 drinks per day for women) and weekly (no more than 14 drinks per week for men, 7 drinks per week for women) drinking guidelines, and to test for sex differences and time effects. College students (n = 992; 58% female) reported daily drinking on a biweekly basis using web-based surveys throughout their first year of college. RESULTS: Women exceeded weekly limits more frequently (15% of weeks [14 to 17%]) than men (12% [10 to 14%]). Women and men exceeded daily drinking limits similarly often (25 and 27%, respectively). In a generalized estimating equations analysis across all 18 biweekly assessments, adjusted for covariates and a linear trend over time, women were more likely to exceed weekly guidelines compared to men. Sex differences in exceeding daily limits were not significant. Over time, rates of exceeding limits declined for daily limits but only for men for weekly limits. CONCLUSIONS: Female college students are more likely to exceed weekly alcohol intake limits than men. Furthermore, trends over time suggest that college students may be maturing out of heavy episodic drinking, but women may not mature out of harmful levels of weekly drinking. The observed disparity in risk for long-term health consequences may represent a missed opportunity for education and intervention.

Fear of dying in panic attacks predicts suicide attempt in comorbid depressive illness: prospective evidence from the National Epidemiological Survey on Alcohol and Related Conditions.

CONTEXT: As a group, comorbid anxiety disorders among depressed persons have consistently been found to increase risk of suicide attempt (SA). Growing evidence supports the link between panic attacks (PAs) and suicidality, but prospective evidence is limited and the nature of the linkage remains unclear. The positive-feedback model of suicide suggests that PAs eliciting catastrophic cognitions may drive SA. OBJECTIVE: To prospectively examine the relationship between PAs, panic symptoms and suicidality in individuals meeting DSM-IV criteria for past-year major depressive episodes in a large epidemiological study. METHODS: In data on 2,864 participants of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) wave 1 and 2 surveys with depressive disorders, the associations of PAs and panic symptoms with subsequent suicidal ideation (SI) and SAs were assessed using logistic regression. RESULTS: Past-year PAs in wave 1 significantly increased odds for subsequent SI and attempt in the 3-year follow-up interval; however, in multivariate analyses, PAs were not a significant predictor, but PAs featuring fear of dying were. Further, among subjects with PAs, fear of dying during a PA increased the odds of subsequent SA sevenfold, even after controlling for comorbid disorders, demographic factors, and other PA symptoms. CONCLUSION: PAs characterized by prominent morbid catastrophic cognitions may mediate the transition to SIs and SAs in subjects with depressive episodes. Presence of these symptoms in clinical settings may serve as a warning sign for future suicidality.

Smoking and suicidality in subjects with bipolar disorder: results from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

BACKGROUND: Smoking in patients with bipolar disorder is known to be related to suicidality. This link has not been investigated, however, in community-based samples. The aim of this study is to delineate the sociodemographic and clinical characteristics of bipolar smokers and examine the relationship between these characteristics and suicidal ideation or attempts in an epidemiologic database, the National Epidemiological Survey on Alcohol and Related Conditions (NESARC). METHODS: Subjects (n = 1,643) with bipolar disorder I and II, defined by the DSM-IV criteria, who had a history of low moods lasting more than 2 weeks were included in our analysis. Current smokers, former smokers, and lifetime nonsmokers were compared in terms of demographic, clinical characteristics, and functional level. Suicidality, evaluated by a history of suicide ideation and attempts while in low mood were compared. RESULTS: Current smokers with bipolar disorder showed a greater number of DSM-IV symptoms while in acute episodes, higher rate of alcohol, and drug use disorders, as well as poorer functional levels than nonsmokers. Previous smokers displayed intermediate characteristics between current smokers and nonsmokers. The logistic regression analysis revealed that current smoking status predicted the risk of having a history of attempted suicide (Odds ratio 1.35, 95% CI: 1.05-1.76) after adjusting for age, sex, race, bipolar subtype, lifetime axis II/anxiety/alcohol use/substance use disorder; however, lifetime smoking status did not. CONCLUSIONS: The present study confirms that current cigarette smoking can predict attempted suicide in a community representative sample of people with bipolar disorder.

Alcoholic liver disease and pancreatitis: global health problems being addressed by the US National Institute on Alcohol Abuse and Alcoholism.

The review article summarizes the mission of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) with focus on the NIAAA's current and future research version for alcoholic liver disease and alcoholic pancreatitis.
