Excessive alcohol use not only causes alcoholic liver disease (ALD) but also increases the risk of liver-related mortality in patients who already have other chronic liver diseases. Screening for alcohol misuse or alcohol use disorder (AUD) among patients with underlying liver disease is essential. This clinical review covers what is known about ALD, the impact of alcohol in patients with underlying liver diseases, current management of alcohol misuse and AUD, and the management of alcohol misuse and AUD specifically in patients with liver diseases. Several treatment options for alcohol misuse and AUD exist such as psychosocial intervention and behavioral and pharmacological therapies. The strategies used in the treatment of alcohol misuse and AUD are still applicable in those who consume alcohol and have underlying liver disease. However, certain medications still need to be carefully used due to potentially worsening already compromised liver function. Screening of ongoing alcohol use in subjects with liver disease is important, and prompt intervention is needed to prevent the associated morbidity and mortality from the detrimental effects of continued alcohol use on underlying liver disease. Considering alcoholism is a complex disease, probably a multidisciplinary approach combining psychotherapy and comprehensive medical care will be the most effective. Future research could focus on identifying additional treatment options for addressing the psychotherapy component since the self-determination and will to quit drinking alcohol can play such a crucial role in promoting abstinence.
The data on the effect of smoking on non-alcoholic fatty liver disease (NAFLD) has been controversial. The aim of this study was to investigate if an association exists between serum cotinine level (a tobacco biomarker) and NAFLD prevalence in the general US population. We conducted a crosssectional analysis of data from the Third National Health and Nutrition Examination Survey (NHANES III). We included 11,003 adults aged 20–74 years who underwent ultrasonography. Of those, 4036 were identified as having NAFLD and 6967 were recognized as controls. The percentage of current smokers was significantly lower in subjects with NAFLD compared with those in controls (21.5% vs 26.0%, p<0.01). After adjustment for potential confounders, there was no association between current or former smokers with NAFLD. Additionally, no associations were observed between the levels of serum cotinine and NAFLD. No association between serum cotinine levels at each quartile level and NAFLD was observed regardless of smoking status. In this large US population-based study, we did not find an association between NAFLD and self-reported smoking status or measured serum cotinine level.
Spirochetes, a genetically and morphologically distinct group of bacteria, are thin, spiral-shaped, and highly motile. They are known causes of several human diseases such as syphilis, Lyme disease, relapsing fever, and leptospirosis. We report a case of colonic spirochetosis in a healthy patient presenting for surveillance colonoscopy. The diagnosis of intestinal spirochetosis was made accidentally during the histological examination of colonic polyps, which were removed during colonoscopy. We also performed an extensive review on intestinal spirochetosis with a focus on clinical presentation and outcomes of reported cases from the past two decades.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
