Understanding the role of modest alcohol consumption in patients with non-alcohol induced fatty liver disease (NAFLD) remains a significant challenge, with no clear guidance on counselling regarding alcohol use. Conventionally, the strong association of alcohol excess and development of complications related to chronic liver disease, including hepatocellular carcinoma, has led practitioners to advocate complete abstinence to those with NAFLD. New evidence published in this issue of the Red Journal challenges the historic paradigm by showing that modest, non-binge wine consumption (

Objective. To evaluate the association of alcohol consumption with risk of rheumatoid arthritis (RA) in two large prospective cohorts, the Nurses' Health Study (NHS) and Nurses' Health Study II (NHS II).

Methods. The NHS established in 1976 that enrolled 121,701 US female registered nurses. The NHSII began in 1989, enrolling 116,430 female nurses. Lifestyle and environmental exposures have been collected through biennial questionnaires. Alcohol consumption was assessed with a food frequency questionnaire completed every 4 years. The incident RA cases were identified using the connective tissue disease screening questionnaire and a medical record review. Separate Cox proportional hazards models were used to estimate hazard ratios (HRs) after adjusting for potential confounders in NHS and NHSII. Pooled HR from two cohorts was estimated using a DerSimonian and Laird random-effect model.

Results. Among 1.90 million years of person-time from 1980 to 2008, 580 incident RA cases were diagnosed in NHS, and among 1.78 million years of person-time from 1989 to 2009, 323 incident RA cases were diagnosed in NHSII. Compared to no use, the pooled multivariable adjusted HR for alcohol use of 5.0-9.9 grams/day (g/d) was 0.78 (95% CI, 0.61-1.00). For seropositive RA cases, the association appeared stronger (HR= 0.69, 95% CI: 0.50-0.95). In addition, Women who drank beer 2-4 times a week had a 31% decreased risk compared with women who never drank beer.

Conclusion. We found a modest association between long-term moderate alcohol drinking and reduced risk of RA. Future studies are needed to confirm our findings in other populations.

OBJECTIVE: To investigate the associations of smoking and alcohol consumption with disease activity and functional status in rheumatoid arthritis (RA).

METHODS: We conducted a prospective study consisting of 662 patients with RA who were followed up to 7 years from the Brigham and Women's Hospital Rheumatoid Arthritis Sequential Study. Smoking and alcohol consumption were assessed through yearly questionnaires. The disease activity and functional status were measured annually by the Disease Activity Score examined in 28 commonly affected joints using C-reactive protein (DAS28-CRP3) and the Modified Health Assessment Questionnaire (MHAQ). Linear mixed models were developed to assess the longitudinal effects of smoking and alcohol consumption on DAS28-CRP3 and MHAQ after adjustment for potential confounders. The HLA-DRB1 shared epitope (HLA-SE) by smoking and alcohol interactions were also evaluated in the analysis.

RESULTS: The median followup time of the cohort was 4 years. Current smoking was not associated with DAS28-CRP3 in our study, but was associated with a higher MHAQ than nonsmokers with seropositive RA (p = 0.05). Alcohol consumption showed an approximate J-shaped relationship with MHAQ, with the minima occurring at 5.1-10.0 g/day. Compared to no alcohol use, alcohol consumption of 5.1-10.0 g/day was associated with a significant decrease of MHAQ (p = 0.02). When stratified by HLA-SE, the effect of alcohol consumption appeared to be stronger in HLA-SE-positive RA than HLA-SE-negative RA.

CONCLUSION: We found that current smoking was associated with a worse functional status, while moderate alcohol consumption was associated with a better functional status in RA. Replications of these findings in other prospective studies are needed

AIM: To investigate the effect of alcohol on the metabolic syndrome (MS) and fatty liver in Japanese men and women.

METHODS: A cross-sectional study was conducted in a medical health checkup program at a general hospital. This study involved 18 571 Japanese men and women, 18-88 years of age, with a mean body mass index of 22.6 kg/m(2). A standardized questionnaire was administered. The total amount of alcohol consumed per week was calculated, and categorized into four grades. Fatty liver was examined by ultrasound modified criteria of the revised National Cholesterol Education Program Adult Treatment Panel III and the new International Diabetes Federation.

RESULTS: The prevalence of fatty liver decreased in men and women with light to moderate alcohol consumption, whereas the prevalence of MS was not so changed. The prevalence of fatty liver of any grade in men was lower than that in those with no or minimal alcohol consumption. In women with light to moderate alcohol consumption, prevalence of fatty liver was lower than that in women with no or minimal alcohol consumption. By logistic regression analysis, the odds ratio (OR) for MS in women with light alcohol consumption was decreased to < 1.0, but this change was not clear in men. The OR for fatty liver was clearly < 1.0 in men with any level of alcohol consumption and in women with light to moderate consumption.

CONCLUSION: Light to moderate alcohol consumption has a favorable effect for fatty liver, but not for MS in Japanese men and women.
