- The Losartan Intervention For End point reduction in hypertension (LIFE) study showed superiority of losartan over atenolol for reduction of composite risk of cardiovascular death, stroke, and myocardial infarction in hypertensives with left ventricular hypertrophy. We compared hazard ratios (HR) in 4287 and 685 participants who reported intakes of 1-7 and >8 drinks/week at baseline, respectively, with those in 4216 abstainers, adjusting for gender, age, smoking, exercise, and race. Within categories, clinical baseline characteristics, numbers randomized to losartan and atenolol, and blood pressure (BP) lowering were similar on the drug regimens. Overall BP control (<140/90 mmHg) at end of follow-up was similar in the categories. Composite end point rate was lower with 1-7 (24/1000 years; HR 0.87, P<0.05) and >8 drinks/week (26/1000 years; HR 0.80, NS) than in abstainers (27/1000 years). Myocardial infarction risk was reduced in both drinking categories (HR 0.76, P<0.05 and HR 0.29, P<0.001, respectively), while stroke risk tended to increase with >8 drinks/week (HR 1.21, NS). Composite risk was significantly reduced with losartan compared to atenolol only in abstainers (HR 0.81 95% confidence interval, CI (0.68, 0.96), P<0.05), while benefits for stroke risk reduction were similar among participants consuming 1-7 drinks/week (HR 0.73, P<0.05) and abstainers (HR 0.72, P<0.01). Despite different treatment benefits, alcohol-treatment interactions were nonsignificant. In conclusion, moderate alcohol consumption does not change the marked stroke risk reduction with losartan compared to atenolol in high-risk hypertensives. Alcohol reduces the risk of myocardial infarction, while the risk of stroke tends to increase with high intake.

Journal article (peer-reviewed)abstract
- We studied the impact of smoking in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study, which showed superiority of losartan over atenolol for reduction of composite risk of cardiovascular death, stroke and myocardial infarction in hypertensives with left ventricular hypertrophy. We compared hazard ratios in 4656 never-smokers, and 3033 previous and 1499 current smokers, adjusting for gender, age, alcohol intake, exercise and race. Composite endpoint rate was higher in previous (28/1000 years), as well as current (39/1000 years) smokers than in never-smokers (21/1000 years). Composite (hazard ratio 0.78, 95% CI 0.65-0.94, p < 0.01) and stroke (hazard ratio 0.61, 95% CI 0.47-0.80], p < 0.001) risks were lower with losartan than atenolol in never-smokers, but not significantly in previous smokers. Drug regimens did not differ in current smokers (composite hazard ratio 0.99, stroke hazard ratio 0.94). Smoking-treatment interactions were non-significant, but a borderline significant trend (p = 0.05) suggested decreasing benefit of losartan vs atenolol for stroke prevention from never- to previous to current smoking status. Smoking increased cardiovascular risk markedly in the LIFE study. The benefit of losartan vs atenolol is consistent with the overall conclusion of the LIFE study, although the treatment effect appeared largest in non-smokers.

The gut microbiota contributes to a mouse model of spontaneous bile duct inflammation

- Background & Aims: A strong association between human inflammatory biliary diseases and gut inflammation has led to the hypothesis that gut microbes and lymphocytes activated in the intestine play a role in biliary inflammation. The NOD.c3c4 mouse model develops spontaneous biliary inflammation in extra- and intrahepatic bile ducts. We aimed to clarify the role of the gut microbiota in the biliary disease of NOD.c3c4 mice. Methods: We sampled cecal content and mucosa from conventionally raised (CONV-R) NOD.c3c4 and NOD control mice, extracted DNA and performed 16S rRNA sequencing. NOD.c3c4 mice were rederived into a germ free (GF) facility and compared with CONV-R NOD.c3c4 mice. NOD.c3c4 mice were also co-housed with NOD mice and received antibiotics from weaning. Results: The gut microbial profiles of mice with and without biliary disease were different both before and after rederivation (unweighted UniFrac-distance). GF NOD.c3c4 mice had less distended extra-hepatic bile ducts than CONV-R NOD.c3c4 mice, while antibiotic treated mice showed reduction of biliary infarcts. GF animals also showed a reduction in liver weight compared with CONV-R NOD.c3c4 mice, and this was also observed in antibiotic treated NOD.c3c4 mice. Co-housing of NOD and NOD. c3c4 mice indicated that the biliary phenotype was neither transmissible nor treatable by co-housing with healthy mice. Conclusions: NOD.c3c4 and NOD control mice show marked differences in the gut microbiota. GF NOD.c3c4 mice develop a milder biliary affection compared with conventionally raised NOD.c3c4 mice. Our findings suggest that the intestinal micro biota contributes to disease in this murine model of biliary inflammation. Lay summary: Mice with liver disease have a gut microflora (microbiota) that differs substantially from normal mice. In a normal environment, these mice spontaneously develop disease in their bile ducts. However, when these mice, are raised in an environment devoid of bacteria, the disease in the bile ducts diminishes. Overall this clearly indicates that the bacteria in the gut (the gut microbiota) influences the liver disease in these mice. (C) 2016 European Association for the Study of the Liver.
