Coffee has hepatoprotective benefits in Brazilian patients with chronic hepatitis C even in lower daily consumption than in American and European populations
Abstract:The potential role of coffee as a hepatoprotective substance for chronic liver diseases has been widely discussed. Our main aim was to evaluate the effect of coffee intake regarding clinical, biochemical tests and liver biopsy data in treatment naïve patients with chronic hepatitis C. One hundred and thirty-six patients with chronic hepatitis C, diagnosed through liver biopsy, or by means of clinical, ultrasound or endoscopic signs of cirrhosis, were assessed by determination of biochemical tests, metabolic an… Show more
“…Thirty articles underwent full-length review, of which 19 articles were excluded because they were not related to hepatitis C (12 articles), did not have controls or comparison of high versus low caffeine intake (5 articles), was a letter to the editor (1 article), or was an abstract (1 article). Eleven studies were included in the qualitative analysis [16][17][18][19][20][21][22][23][24][25][26], and five studies were included in the meta-analysis [17,[21][22][23][24]. Fig.…”

The pooled OR of advanced hepatic fibrosis in patients who had higher caffeine intake was 0.39 (95% CI: 0.21-0.72) (Fig.…”

“…The liver fibrosis staging scale used to quantify the degree of liver fibrosis varied among studies. The METAVIR scoring system was used in four studies [17,21,22,24], and the Ishak score was used in one study [23]. Hepatic fibrosis was evaluated by liver biopsy in four studies [17,[22][23][24], and by the FibroSURE (BioPredictive, Paris, France) test in one study [21].…”

“…It has long been aware of the beneficial effects of coffee on serum liver enzymes and the alcoholic liver disease, but since 2009 several studies have shown that caffeine intake, especially in the form of coffee, has a protective effect on the development of hepatitis C virus (12,14,21,22) . In our previously published study (21) , we observed a reduction in liver fibrosis in patients taking higher doses of caffeine in univariate and multivariate analysis when compared to patients with lower daily intake of caffeine, but did not observe a relationship between caffeine with inflammatory activity in liver biopsy. We drew attention fact that the amount of caffeine necessary to reduce the degree of fibrosis was significantly lower than in English literature (125 mg or only 4 Brazilian cups of coffee versus 250 mg or 308 mg daily).…”
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.
