Reducing statin dosage by a nutraceutical approach
Reducing statin dosage has been a major issue with patients and some doctor as well. In this study, the authors found a creative approach to select patients that could be adequately treated with half of their original statin dosage + smart food choices. Diabetic Patients (N=53) using statins were given a combination of fish oil (1.7g EPA + DH/day), chocolate containing plant sterols (2.2g/day) and green tea (two sachets per day). After 6 weeks of this pilot protocol the “good responders” where provide with additional supplements for 12 weeks, and their statin dosage was kept during the first 6 weeks but reduced by 50% from week 6 – week12. In the pilot phase using the supplements improved LDL-c (-13.7% ± 3.7, p=0.002) and hsCRP (-35.5% ± 5.9, p=0.03) Based on cholesterol synthesis/absorption markers the LDL-c reduction was related to a decrease in cholesterol absorption. After phase two, and with 50% of the statin dosage, no changes in the above-mentioned markers as well as cholesterol efflux or HDL particles were observed. The authors suggest that their nutraceutical approach to reduce statin dosage in patients unable to tolerate the full doses can be an alternative approach. Strategies to elucidate novel markers that characterize “good responders” will need to be explored.

The effect of statins on neuro-cognitive functions are somewhat contradictory. In this narrative review, the authors explain this Janus type of effect of statins. Reports of reversible cognitive impairment in individual statin users seem to be valid, exposure to increased statin concentrations in plasma puts these patients at risk of adverse effects including cognitive impairment. Lipophilic statins and metabolic syndrome patients are more frequently reporting CNS side effects. In larger observational studies statins were associated with a lower risk of dementia and Alzheimer’s disease and even improved cognitive loss. Starting statins in mid-life as opposed to later in life is associated with reduced cognitive decline and the authors suggest that vascular benefits could be the explanation for these early protective effects. Randomized controlled trials have not been able to provide hard evidence of the benefits that surfaced in observational trials. The authors provide a comprehensive overview of the mechanisms that explain the contradictory findings and that could help health care professionals select the patients that would be more likely to benefit as well avoid statins in patients that have a higher risk of experiencing the harmful effects. The ultimate proof will be to evaluate the appropriate patients in well-designed RCT’s. Patients with hyperlipidemia and starting in mid-life as opposed to later in life would be the appropriate population to evaluate the benefits of statin use on cognitive impairment.

Are outcomes different in statin trials with a run in phase compared to no run in phase?
Numerous statin trials have employed run in strategies to ensure proper adherence and tolerance to the study medication. Post hoc, critics have argued that this would provide less reliable information on statin safety because patient intolerant to statins would be filtered out. In this meta-analysis of statins trials with and without a run-in design the authors aimed to evaluate if there were different efficacy and safety outcomes when these compared. Although the 10 trials with a run-in phase included more randomized patients, compared to the 6 no-run in phase trials; N=6 699 vs N=903 respectively; A higher percentage of patients completed the trial when a run-in phase was used, 88% vs 78%, but this difference was not statistically significant. All other evaluated results in the two types of trials were nearly identical. The authors suggest using a run-in phase design wastes scarce clinical trials resources but they acknowledge that replicating the presented results is needed to confirm their findings.

Statins have a favorable effect on vulnerable carotid plaque features
The Dutch Rotterdam study is prospective population-based cohort of Participants > 45 years living in Ommoord a district of the city of Rotterdam Between 2007 and 2012 all participants had an ultrasound of the carotid arteries. Patients with an IMT > 2.5 mm (N=2666), were selected for this follow-up protocol and had and MRI examination of their carotid arteries. Ultimately 1740 participants were evaluated for this present analysis. Mean age 72.9 years and 46% females. The following parameters were studied: presence of calcification, lipid core, and intra-plaque hemorrhage. Statin use, and duration were extracted from pharmacy records. Statin use was associated with calcification OR 1.73(1.22-2.44) and prolonged use re-enforced this association OR 1.82 (1.00-3.33) 10 – 40 months and 1.74 (1.09-2.77) >48 months vs OR 1.65 (0.94-2.89) < 10 months. A reduced Lipid core was associated with current statin use if statins were used for <10 months and only when higher statin dosages were used (DDD> 1.33). Increased calcifications were observed in all statin users. Of note was the observation that statin discontinuation for 3 months or longer was associated with a higher presence of vulnerable components, such as increased lipid core, and intra- plaque hemorrhage, underlining the importance of continuing statins. The authors concluded that active high dose statin use was associated with a reduction of carotid plaque features associated with vulnerable plaques.
