Thrombosis following Covid-19 vaccination: a possible role of alcohol consumption? A suggestion from the Italian Society on Alcohol

Alcohol use disorders, self-help groups as a supplement to pharmacological and psychological therapy? A retrospective study in a population with alcohol related liver disease

BACKGROUND

According to the new criteria in the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-V), the prevalence of alcohol use disorders (AUDs) is 20-30% in men and 10-15% in women worldwide.2,3 The anticraving therapy/psychotherapy combination is currently used routinely in clinical practice. However, the results after one year are unsatisfactory. Meta-analytic studies found failure rates of 57 to 75%. These percentages vary in relation to the intensity and length of the treatment. In addition, the abstinence rates gradually decrease over time. In this study, the clinical outcome of alcohol related liver disease (ALD) patients who spontaneously attended self-help groups (SHGs) (club of alcoholics in treatment - multi-family community/ alcoholics anonymous) regularly versus those who did not want to start the path or did not complete it was evaluated.

METHODS

From January 2005 to December 2010, 1337 alcohol use disorder patients affected by compensated alcohol related liver disease, were prospectively followed and retrospectively assessed. Two hundred thirty-one patients were enrolled: 74 attended self-help groups assiduously, 27 attended sporadically and 130 refused participation in SHGs.

RESULTS

Constant attendance at SHGs compared to non-attendance allows for a significant increase (<0.0001) in the period of sobriety found in the median of distribution. Frequent attendance at SHGs is effectively "preventive," reducing the fraction of relapses by about 30%. The percentage of cases of cirrhosis is significantly different (P=0.0007) between those who have regularly attended SHG meetings (about 1% of patients) and those who have never attended or only occasionally (various percentages between 21 and 31% of patients); in both groups the incidence of new cases would seem to be 0.014 cases/ year. Similar difference in percentages regarding the onset of hepatocellular carcinomas (HCCs), although with a lower level of significance (P=0.017) among those who attended regularly, 4% of patients with an incidence of 0.006 cases/ year, compared to those who have never attended or only occasionally: over 14% of patients with an incidence of 0.022 cases/year.

CONCLUSIONS

This study suggests the importance of attending SHGs not only for the long-term achievement of alcoholic abstention, but also in positively influencing the course of alcohol-related diseases.

COVID-19 and alcohol consumption: recommendations in the Omicron era

In the early stages of the pandemic, the first reports began that alcohol consumption could increase the risk of becoming infected and worsening the prognosis disease. This is for two reasons: behavioral and socio-economic factors that characterize a part of this population can be the cause of viral spread and a direct or indirect negative action of ethanol on the immune system. The data used for the preparation of these recommendations are based on a detailed analysis of the scientific literature published before March 31, 2022 (Web of Science, Scopus, Google Scholar). Furthermore, in the process of developing this work, we consulted the guidelines/position papers of the Italian Society on Alcohol and of the World Health Organization. It has been confirmed that AC is in COVID-19 era a risky behavior and that AUD and substance use disorder (SUD) patients are certainly at greater risk of contracting infection and also of having a worse course. In light of what has been said, some recommendations can be made: correctly inform the general population that AC negatively interacts with COVID-19 infection; reducing the COVID-19 risk by advocating healthy lifestyle habits (smoke, diet, physical exercise, etc.) and preferential policies in population with comorbidities; implement actions that reduce the average consumption of alcohol by avoiding hazardous/harmful consumption. Abstention is better; identify alcohol consumption through a more in-depth alcohol history, using the AUDIT; AUDs patients are frail patients deserving a complete vaccination course; suggest a period of alcoholic abstention of at least thirty days before vaccination to be maintained for the following fifteen days; promoting health education campaigns for young people in order to promote vaccination culture and correct lifestyles.
