Abstract
BACKGROUND The relevance of the IMPROVE-IT trial on real-life practice has not been explored in patients with ACS. METHODS A prospective Swiss cohort of 6266 patients hospitalized for ACS between 2009 and 2017 with a one-year follow-up. The primary endpoints were the ezetimibe use overall or in combination with high-intensity statin at discharge and at one year after ACS. Secondary endpoint was LDL-C target achievement at one year in a subsample of 2984 patients. Relative Ratios (RR) were used to assess changes in primary endpoints before and after the publication of IMPROVE-IT, adjusting for age, sex, diabetes, prior myocardial infarction, LDL-C and attendance to cardiac rehabilitation. RESULTS The period following the publication of the IMPROVE-IT trial was associated with a steady increase in the use of ezetimibe at discharge (from 1.8% to 3.8%, P < 0.001, adjusted RR 2.85, 95% CI 1.90-4.25) and at one year (from 5.0% to 13.8%, P < 0.001, adjusted RR 3.00, 95% CI 2.40-3.75). The combination of high-intensity statin and ezetimibe rose from 0.9% to 2.1% at discharge (P < 0.001, adjusted RR 3.35, 95% CI 1.90-5.89) and from 2.1% to 7.8% at one year (P < 0.001, adjusted RR 3.98, 95% CI 2.90-5.47). The period following the publication of the IMPROVE-IT trial was associated with an improvement of LDL-C target <1.8 mmol/L (adjusted RR 1.37, 95% CI 1.12-1.68). CONCLUSIONS After the publication of the IMPROVE-IT trial, the use of ezetimibe was increased by three-fold in a large contemporary cohort of ACS patients, concomitant with an improved LDL-C target achievement.

Abstract
BACKGROUND/AIMS: Sodium taurocholate co-transporting polypeptide (NTCP) is the receptor for the hepatitis B virus (HBV) and hepatitis D virus (HDV) entry into hepatocytes. Ezetimibe is a cholesterol-lowering drug that possesses the pharmacophore features to inhibit NTCP. This study evaluates the efficacy of ezetimibe in patients with chronic HDV infection in a nonrandomized trial. MATERIALS AND METHODS This proof of concept phase 2 trial evaluated the efficacy and safety of ezetimibe 10 mg daily in (interferon treatment-experienced or interferon ineligible) patients with chronic hepatitis D (CHD). Forty-four patients with CHD were recruited, 38 male and 6 female patients, mean age 35.2±8.7 (range 19-64). Fifteen (34%) patients were on concomitant nucleoside therapy, and cirrhosis was present in 14 subjects. The primary therapeutic endpoint was a decline in HDV RNA at one log or more from the baseline at week 12. RESULTS The mean HDV RNA level was 5.4±1.3 log10 IU/mL. HBeAg was non-reactive in 43 (98%). HBV DNA was undetectable in 28 (64%). One patient stopped treatment at week 4, and one patient did not follow-up. One log or more reduction in the HDV RNA levels was observed in 18/44 (41%) patients. No log reduction occurred in 16 patients, and 8 experienced a log increase. No adverse effects from the concomitant nucleoside analogue use or clinical cirrhosis were observed. The drug exhibited a positive safety profile. CONCLUSION Treatment of CHD patients with ezetimibe resulted in a one log reduction of viral load in 43% (18/42) of the patients who completed the 12 weeks of therapy.
