The effects of Vitamin D supplementation on statin adherence
The effects of vitamin D supplementation in improving adherence to statins was explored in a secondary analysis of the long-term statin therapy in the Vitamin D Assessment (VIDA) study. A large population-based placebo controlled randomized trial to evaluate the effects of monthly vitamin D (100 000 IU) supplementation on cardiovascular disease and other health outcomes. The trial lasted from 2011 until 2015 and 2494 out of the 5110 participants were on long term statin therapy. Adherence (proportion of days covered by prescriptions >80%)and persistence (non-discontinuation of the statin therapy following an allowed 30 days gap between refills). Overall no effects on compliance were observed (RR 1.01; p=0.62) but improved persistence (RR: 1.15; p<0.02) was noted. Simvastatin users did show improved adherence as well, at 6-months (RR 1.10; p<0.01), 12-months (RR 1.09; p=0.05), and 24- months (RR 1.09; p=0.04). The authors concluded that vitamin D supplementation could increase compliance and persistence to statins, especially for simvastatin users; additional long-term studies are needed to confirm these preliminary findings.

Friedewald formula update?
Determining precise LDL-c levels is important to determine statin initiation as well as determining dosage selection. In many laboratories LDL-c is calculated using the Friedewald formula: LDL-c = Tc – HDL-c – Tg/5 (in mg/dL). The authors evaluated the accuracy of the Friedewald method with a novel formula (LDL-Cc= TC –HDL-c – TG/adjustable factor) to determine statin eligibility according to the 2013 ACC/AHA guidelines. Using data collected in the NHANES (2005–2014) cohort, 5302 US adults aged between 40 and 75 years and without history of atherosclerotic cardiovascular disease 0.2% (0.0-0.8) and 0.4% (0.3-0.6) would no longer qualify or be newly eligible for statin treatment. In patients with TG’s ≥150 mg/dl and LDL-c ≤70 mg/dl (based on the Friedewald formula) 11.6% (4.0–29.3) would become newly eligible for the statin treatment. The authors suggested that reassessment with the novel LDL-c calculating method, would lead to a small net increase for statin eligibility in patients with TG’s ≥150 mg/dl and LDL-c ≤70 mg/dl.

Novel method versus the Friedewald method for estimating low-density lipoprotein cholesterol in determination of the eligibility for statin treatment for primary prevention in the United States.Medicine (Baltimore) 2018; 97:e0612. http://www.ncbi.nlm.nih.gov/pubmed/?term=29703063 BP improvements independent of statin type or dosage
Blood pressure (BP) reductions have been observed in trials/registries where statins were evaluated. Between 2007 and 2017 the effects of different statins on BP was studied in this observational, cross sectional analysis of 987 hypertensive Italian outpatients. They were all managed in a single hypertension unit, were using statins and had a 24-hour ambulatory blood pressures recording. Patients were allocated to 4 groups: 291 (29.5%) on simvastatin 10-80 mg/d, 341 (34.5%) on atorvastatin 10-80 mg/d, 187 (18.9%) on rosuvastatin 5-40 mg/d, and 168 (17.0%) on other statins. All patients showed similar BP reducing effects, except for superior “in Clinic” (P=0.007) and “daytime“ (P=0.13) diastolic blood pressures values of the patients using simvastatin or atorvastatin compared to the individuals taking other statins. The authors suggest that the BP lowering effects of statins is a class effect, not related to either statin type or the dosage, however additional research is warranted to confirm these observational findings.

Meta-analysis on statins and liver safety or transaminase increases?
The title of this systematic review and meta-analysis is confusing because no information on liver disease of liver complications were presented. The authors did analyze the effects of statin on transaminase increases. Of note no trials with rosuvastatin and only one relatively small trial with atorvastatin was included in this analysis. What they observed is that based on the 16 included studies and 74 078 patients that participated in these clinical trials, transaminases increased and that there was a borderline dose dependent statistical significant effect. OR: 1.18 (1.01-1.93; p=0.04). Intriguingly most robust, and again of borderline significance, effects were observed for Fluvastatin; OR: 3.50 (1.07-11.53; p=0.04). Higher statin dosages (≥40 mg/day) also showed a more pronounced, but not unexpected, impact; OR: 3.62 (1.52-8.65; p=0.004). Recently the detrimental effects of transaminase increases, frequently observed in patients using statins, have been questioned. The reports of serious liver diseases related to statin use are scant and an accumulating numbers studies show improved hepatic outcomes in patients with liver disease that use HMG-CoA reductase inhibitors. The title suggests that statins can compromise liver safety, this seems incorrect as no data is presented in the article to support this. The interpretation of the title and the manner how the results are discussed could persuade doctors to limit statin use in patients with elevated transaminases, as to prevent liver damage. However the inflicted harm of not prescribing statins in (very) high risk patients, because of increased transaminase levels (e.g. DM2/MS + NAFLD/NASH), could have serious consequences in terms an increased risk of fatal and non-fatal ASCVD complications, that far outweigh the risk of serious liver damage.

Simple, effective strategies to improve statin adherence
In this qualitive review, German GP’s were interviewed to share their experience on statin adherence. In the article barriers, as well as approaches to improve long term statin adherence are presented. Socio-demographic characteristics such as low educational level and older age were seen as important hurdles for adherence by all participants. Although patients with a higher educational level were more likely to continue using taking their statins, they were more concerned about statin benefits as well. Fears of (muscle) related side effects and the effect this could have on their quality of life . GP’s were inclined not to discuss side effects with anxious patients, and as a consequence they were less frequently quizzed about complaints. However, all GP’s were convinced that less informed patients would be more vulnerable to negative media attention and non-expert opinions, factors that could not only affect statin adherence, but the doctor-patient relationship as well. A small number of GP’s were concerned that for primary prevention statins would be a substitute for lifestyle changes and were inclined to stop statins on patient’s requests. The most successful methods to improve adherence, were repeated motivation through patient education as well as patient-centered care. Some GP’s employed specific tools or strategies, such as printed therapy plans, frequently measuring LDL-c levels, checking prescription refill records. All GP’s stressed the importance of a long term therapeutic relationship to achieve guideline recommended LDL-c targets. Using a person centered approach to overcome concerns and resistance as well as to properly address perceived sided effects, were recommendations that all GP’s agreed on. This would include individual risk assessment combined with shared decision-making. The simple, straightforward advice shared in this review is helpful for clinicians managing patients where statins are indicated.
